MERGER PROPOSAL—YOUR VOTE IS VERY IMPORTANT

 
   
LOGO   LOGO

Dear stockholders of US Ecology, Inc. and stockholders of NRC Group Holdings Corp.:

            As previously announced, the board of directors of US Ecology, Inc. ("US Ecology") and the board of directors of NRC Group Holdings Corp. ("NRCG") have each approved that certain Agreement and Plan of Merger, dated as of June 23, 2019 (as it may be amended from time to time, the "Merger Agreement"), pursuant to which ECOL Merger Sub, Inc., a wholly-owned subsidiary of US Ecology Parent, Inc. ("Holdco"), which is in turn a wholly-owned subsidiary of US Ecology, will be merged with and into US Ecology, with US Ecology as the surviving entity and continuing as the wholly-owned subsidiary of Holdco (the "ECOL Merger"), and Rooster Merger Sub, Inc., a wholly-owned subsidiary of Holdco, will be merged with and into NRCG, with NRCG as the surviving entity and continuing as the wholly-owned subsidiary of Holdco (the "NRCG Merger," and together with the ECOL Merger, the "Mergers"). Following the Mergers, Holdco will change its name to "US Ecology, Inc."

            If the transaction is completed, NRCG common stockholders will have the right to receive (1) 0.196 of a share of common stock of Holdco, par value $0.01 per share ("Holdco Common Stock") for each share of common stock of NRCG, par value $0.0001 per share ("NRCG Common Stock"), they own at the closing of the NRCG Merger, (2) any cash paid in lieu of fractional shares of Holdco Common Stock payable pursuant to the Merger Agreement and (3) any dividends or other distributions to which the holder thereof becomes entitled to upon the surrender of such shares of NRCG Common Stock. Holders of shares of NRCG 7.00% Series A Convertible Cumulative Preferred Stock, par value $0.0001 per share ("NRCG Series A Preferred Stock") will have the right to receive (1) a whole number of shares of Holdco Common Stock equal to the product of (a) the number of shares of NRCG Common Stock that such shares of NRCG Series A Preferred Stock could be converted into at the effective time of the Mergers (the "Effective Time") (including Fundamental Change Additional Shares and Accumulated Dividends (each, as defined in the Certificate of Designations, Preferences, Rights and Limitations of NRCG Series A Preferred Stock, dated as of October 17, 2018 and corrected on October 23, 2018, establishing the rights of the NRCG Series A Preferred Stock)) multiplied by (b) 0.196, (2) any cash paid in lieu of fractional shares of Holdco Common Stock payable pursuant to the Merger Agreement and (3) any dividends or other distributions to which the holder thereof becomes entitled to upon the surrender of such shares of NRCG Series A Preferred Stock. US Ecology stockholders will have the right to receive one share of Holdco Common Stock for each share of common stock of US Ecology, par value $0.01 per share ("ECOL Common Stock") they own at closing and any dividends or other distributions to which the holder thereof becomes entitled to upon the surrender of shares of ECOL Common Stock. Each holder of an outstanding warrant to purchase NRCG Common Stock (each, a "NRCG Warrant") issued pursuant to that certain Warrant Agreement, dated as of June 22, 2017 (the "NRCG Warrant Agreement"), between Continental Stock Transfer & Trust Company and NRCG, will have the right to receive a replacement warrant (each, a "Replacement Warrant") that will be exercisable for a number of shares of Holdco Common Stock equal to the product (rounded to the nearest whole number) of (1) the number of shares of NRCG Common Stock that would have been issuable upon the exercise of the NRCG Warrant immediately prior to the Effective Time and (2) 0.196, at an exercise price equal to the quotient obtained by dividing (a) the pre-NRCG Merger exercise price ($11.50 per share) by (b) 0.196.

            The exchange ratio is fixed and will not be adjusted to reflect stock price changes prior to the closing of the Mergers. Based on the closing price of ECOL Common Stock on the Nasdaq Global Select Market ("Nasdaq") of $62.74 on June 21, 2019, the last trading day before public announcement of the Mergers, the merger consideration represented approximately $12.00 of aggregate value for each share of NRCG Common Stock, based on the US Ecology volume weighted average share price over the last 15 trading days prior to the signing of the Merger Agreement. Based on the ECOL Common Stock closing price of $61.74 on September 6, 2019, the latest practicable date before the date of this document, the merger consideration represented approximately $12.10 of aggregate value for each share of NRCG Common Stock. We encourage you to obtain current market quotations of ECOL Common Stock and NRCG Common Stock before voting.

            Upon completion of the Mergers, we estimate that current US Ecology stockholders will own approximately 70% of the combined company on a fully diluted basis and then former NRCG stockholders will own approximately 30% of the combined company on a fully diluted basis. ECOL Common Stock is traded on Nasdaq under the symbol "ECOL" and NRCG Common Stock and NRCG Warrants are traded on the NYSE American LLC (the "NYSE American") under the symbol "NRCG" and "NRCG.WS," respectively. Upon completion of the NRCG Merger, NRCG Common Stock and NRCG Warrants will cease to be traded on the NYSE American. Upon completion of the ECOL Merger, ECOL Common Stock will cease to be traded on Nasdaq, but Holdco Common Stock and the Replacement Warrants will trade on Nasdaq under the symbols "ECOL" and "ECOLW", respectively.

            At the special meeting of US Ecology stockholders to be held on October 23, 2019 (the "US Ecology Special Meeting"), US Ecology stockholders will be asked to vote on a proposal to (1) adopt the Merger Agreement (the "US Ecology Merger Agreement Proposal"), (2) approve the issuance of Holdco Common Stock pursuant to the terms and conditions set forth in the Merger Agreement (the "Holdco Stock Issuance Proposal"), (3) amend and restate the Holdco charter as further described in the accompanying joint proxy statement/prospectus (the "Holdco Charter Amendment Proposal"), and (4) approve adjournments of the US Ecology Special Meeting to solicit additional proxies if there are not sufficient votes at the time of the US Ecology Special Meeting to approve the US Ecology Merger Agreement Proposal, the Holdco Stock Issuance Proposal or the Holdco Charter Amendment Proposal or to ensure that any supplement or amendment to the accompanying joint proxy statement/prospectus is timely provided to US Ecology stockholders (the "US Ecology Adjournment Proposal").

            At the special meeting of NRCG common stockholders to be held on October 22, 2019 (the "NRCG Special Meeting"), NRCG common stockholders will be asked to vote on a proposal to (1) adopt the Merger Agreement (the "NRCG Merger Agreement Proposal") and (2) approve adjournments of the NRCG Special Meeting to solicit additional proxies if there are not sufficient votes at the time of the NRCG Special Meeting to approve the NRCG Merger Agreement Proposal or to ensure that any supplement or amendment to the accompanying joint proxy statement/prospectus is timely provided to NRCG common stockholders (the "NRCG Adjournment Proposal").

            We cannot complete the Mergers unless the NRCG common stockholders and the US Ecology stockholders approve the respective proposals related to the Mergers. To the US Ecology stockholders and NRCG common stockholders, as applicable, your vote is very important, regardless of the number of shares you own. Whether or not you expect to attend the US Ecology Special Meeting or NRCG Special Meeting, as applicable, in person, please cause your shares to be voted as promptly as possible by (1) accessing the Internet website specified on your proxy card, (2) calling the toll-free number specified on your proxy card or (3) signing and returning all proxy cards (holders of common stock only) that you receive in the postage-paid envelope provided, so that your shares may be represented and voted at the US Ecology Special Meeting or the NRCG Special Meeting, as applicable.

            The US Ecology board of directors recommends that US Ecology stockholders vote "FOR" the US Ecology Merger Agreement Proposal, the Holdco Stock Issuance Proposal, the Holdco Charter Amendment Proposal and, if necessary, "FOR" the US Ecology Adjournment Proposal.

            The NRCG board of directors recommends that NRCG common stockholders vote "FOR" the NRCG Merger Agreement Proposal and, if necessary, "FOR" the NRCG Adjournment Proposal.

            Pursuant to Section 262 of the Delaware General Corporation Law ("Section 262"), notice is hereby given that, in connection with the NRCG Merger and as further explained in the accompanying joint proxy statement/prospectus, holders of NRCG Series A Preferred Stock are entitled to appraisal rights under Section 262, a copy of which is attached as Annex J to the accompanying joint proxy statement/prospectus. Any holder of NRCG Series A Preferred Stock seeking to demand appraisal of its shares of NRCG Series A Preferred Stock, or wishing to preserve its right to do so, should review carefully Section 262 and the accompanying joint proxy statement/prospectus. Additionally, notice is hereby given that (1) the anticipated effective date of the NRCG Merger is November 1, 2019 and (2) dividends on shares of NRCG Series A Preferred Stock will cease to accrue on the date immediately preceding the effective date of the NRCG Merger.

            The obligations of US Ecology and NRCG to complete the Mergers are subject to the satisfaction or waiver of several conditions set forth in the Merger Agreement. More information about US Ecology, NRCG and the Mergers is contained in the joint proxy statement/prospectus. US Ecology and NRCG encourage you to read the entire joint proxy statement/prospectus carefully, including the section entitled "Risk Factors" beginning on page 36 of the joint proxy statement/prospectus.

            We look forward to the successful completion of the Mergers.

 
   
Sincerely,   Sincerely,

QUESTIONS AND ANSWERS ABOUT THE MERGERS AND THE SPECIAL MEETINGS

        The following are brief answers to certain questions that US Ecology stockholders and NRCG stockholders may have regarding the Mergers (as defined above), the Merger Agreement (as defined above), the issuance of shares of Holdco Common Stock (as defined below) in connection with the Mergers, the special meeting of US Ecology stockholders (the "US Ecology Special Meeting"), the special meeting of NRCG common stockholders (the "NRCG Special Meeting"), and other matters to be considered at the US Ecology Special Meeting and at the NRCG Special Meeting. US Ecology and NRCG urge you to read carefully the remainder of this joint proxy statement/prospectus and additional important information contained in the annexes and exhibits to, and the documents incorporated by reference into, this joint proxy statement/prospectus because the information in this section may not provide all of the information that might be important to you in determining how to vote. See the section entitled "Where You Can Find More Information" in this joint proxy statement/prospectus.

Q:
What is the proposed transaction?

A:
As previously disclosed, on June 23, 2019, US Ecology, Holdco, ECOL Merger Sub, Rooster Merger Sub and NRCG entered into the Merger Agreement. A copy of the Merger Agreement is attached to this joint proxy statement/prospectus as Annex A.

Under the terms of the Merger Agreement, ECOL Merger Sub will merge with and into US Ecology, with US Ecology as the surviving entity and continuing as a wholly-owned subsidiary of Holdco and, simultaneously therewith, Rooster Merger Sub will merge with and into NRCG, with NRCG as the surviving entity and continuing as a wholly-owned subsidiary of Holdco.

In the ECOL Merger, each share of common stock, par value $0.01 per share, of US Ecology ("ECOL Common Stock") issued and outstanding immediately prior to the effective time of the Mergers (the "Effective Time") (other than cancelled shares) will be converted into the right to receive (1) one share of common stock, par value $0.01 per share, of Holdco ("Holdco Common Stock") and (2) any dividends or other distributions to which the holder thereof becomes entitled to upon the surrender of shares of ECOL Common Stock in accordance with the Merger Agreement. Outstanding equity awards of US Ecology will be assumed by Holdco and converted into equity awards at Holdco on a one-for-one basis as set forth in the Merger Agreement and described herein under the section entitled "The Merger Agreement—Treatment of US Ecology Stock Options, Restricted Stock Units, Performance Stock Units and Restricted Shares." Each share of ECOL Common Stock that is held by US Ecology as treasury stock or that is owned by Holdco, ECOL Merger Sub, US Ecology or any of their respective direct or indirect wholly-owned subsidiaries as of immediately prior to the Effective Time will automatically be cancelled and will cease to exist, without any conversion thereof, and no consideration will be delivered in exchange therefor.

In the NRCG Merger, each share of common stock, par value $0.0001 per share, of NRCG ("NRCG Common Stock") issued and outstanding immediately prior to the Effective Time (other than cancelled shares) will be converted into the right to receive, and become exchangeable for (1) 0.196 (the "NRCG Exchange Ratio") of a share of Holdco Common Stock for each share of NRCG Common Stock, (2) any cash in lieu of fractional shares of Holdco Common Stock payable pursuant to the Merger Agreement and (3) any dividends or other distributions to which the holder thereof becomes entitled to upon the surrender of such shares of NRCG Common Stock in accordance with the Merger Agreement. Each share of 7.00% Series A Convertible Cumulative Preferred Stock, par value $0.0001 per share, of NRCG (the "NRCG Series A Preferred Stock") issued and outstanding immediately prior to the Effective Time will be converted into the right to receive, and become exchangeable for (1) a whole number of shares of Holdco Common Stock equal to the product of (a) the number of shares of NRCG Common Stock that such share of

Q:
What is the value of the merger consideration?

A:
US Ecology stockholders will be entitled to receive one share of Holdco Common Stock for each share of ECOL Common Stock they own at the closing of the ECOL Merger, and NRCG stockholders will be entitled to receive a fixed number of shares of Holdco Common Stock for each share of NRCG Common Stock or NRCG Series A Preferred Stock (based on the number of shares of NRCG Common Stock that such share of NRCG Series A Preferred Stock could be converted into at the Effective Time (including Fundamental Change Additional Shares and Accumulated Dividends (each, as defined in the NRCG Series A Certificate of Designation))) as applicable, they own at the closing of the NRCG Merger based on the NRCG Exchange Ratio of 0.196 shares of Holdco Common Stock per share of NRCG Common Stock, rather than a number of shares of Holdco Common Stock with a particular fixed market value. Because the NRCG Exchange Ratio and the conversion mechanics are fixed and will not be adjusted to reflect any changes in the market prices of ECOL Common Stock or NRCG Common Stock, the market value of the Holdco Common Stock issued in the ECOL Merger or the NRCG Merger, as

Q:
Why is US Ecology seeking stockholder approval to amend the Holdco charter?

US Ecology stockholders are being asked to consider and vote upon a proposal to add certain provisions to the charter of Holdco that will be in effect after completion of the Mergers and that are not in the current charter of US Ecology. These provisions are proposed to be added to the proposed Holdco Amended Charter to facilitate Holdco's compliance with the U.S. citizen ownership requirements of the U.S. coastwise trade laws, which are principally contained in 46 U.S.C. Chapters 121, 505 and 551 and the related regulations and are commonly referred to collectively as the "Jones Act," following the closing of the Mergers.

Q:
What vote is required to approve each proposal at the US Ecology Special Meeting?

A:
The US Ecology Merger Agreement Proposal and the Holdco Charter Amendment Proposal each requires the affirmative vote of holders of a majority of the issued and outstanding shares of ECOL Common Stock entitled to vote on the proposal. Failures to vote, abstentions and broker non-votes will have the effect of a vote against the US Ecology Merger Agreement Proposal and the Holdco Charter Amendment Proposal.

The Holdco Stock Issuance Proposal and the US Ecology Adjournment Proposal each requires the affirmative vote of the majority of all votes cast at the US Ecology Special Meeting and entitled to vote thereon. Failures to vote, abstentions and broker non-votes will have no effect on the outcome of the Holdco Stock Issuance Proposal or the US Ecology Adjournment Proposal, assuming a quorum is present.

Q:
What vote is required to approve each proposal at the NRCG Special Meeting?

A:
The NRCG Merger Agreement Proposal requires the affirmative vote of holders of a majority of the issued and outstanding shares of NRCG Common Stock entitled to vote on the proposal. Failures to vote, abstentions and broker non-votes will have the effect of a vote against the NRCG Merger Agreement Proposal. NRCG common stockholder approval of the NRCG Merger Agreement Proposal is a condition precedent to the consummation of the Mergers.

The NRCG Adjournment Proposal requires the affirmative vote of the majority of all votes cast at the NRCG Special Meeting and entitled to vote thereon. Failures to vote, abstentions and broker non-votes will have no effect on the outcome of the NRCG Adjournment Proposal.

JFL-NRC-SES Partners, LLC ("JFL Partners"), JFL-NRCG Holdings III, LLC ("JFL Holdings III") and JFL-NRCG Holdings IV, LLC ("JFL Holdings IV" and collectively, the "JFL Entities"), are the registered holders of approximately 66% of the issued and outstanding NRCG Common Stock as of the NRCG Record Date, and have agreed, among other things, to vote their shares of NRCG Common Stock in favor of the adoption of the Merger Agreement at the NRCG Special Meeting, with certain exceptions described in this joint proxy statement/prospectus. As a result, and subject to the terms of the Support Agreement (as defined below), the approval of the NRCG Merger Agreement Proposal is effectively assured. Furthermore, at the close of business on the NRCG Record Date, approximately 70% of the issued and outstanding shares of NRCG Common Stock were directly held by NRCG's directors and executive officers and the JFL Entities. For additional information regarding the ownership of NRCG's directors, executive officers and certain stockholders, see the section entitled "Security Ownership of Certain Beneficial Owners and Management of NRCG."

Q:

A:
US Ecology Special Meeting:    Stockholders who hold shares representing at least a majority of the issued and outstanding shares of ECOL Common Stock entitled to vote at the US Ecology Special Meeting must be present in person or represented by proxy to constitute a quorum for the transaction of business at the US Ecology Special Meeting. If a quorum is not present, the US Ecology Special Meeting may be adjourned by the chairman of the US Ecology Special Meeting or the holders of a majority of shares of the ECOL Common Stock entitled to vote who are present, in person or by proxy, to another place, date, or time without notice other than announcement at the meeting, until a quorum shall be present or represented. Abstentions and broker non-votes are not included in the determination of the number of votes cast at the US Ecology Special Meeting, but abstentions and broker non-votes, if any, will be counted for purposes of determining whether a quorum is present.

A:
The NRCG Board has determined that the Merger Agreement and the transactions contemplated thereby, including the Mergers, are fair, advisable and in the best interests of NRCG and its common stockholders.

Q:
My shares are held in "street name" by my broker, bank or other nominee. Will my broker, bank or other nominee automatically vote my shares for me?

A:
No. If your shares are held in the name of a broker, bank or other nominee, you are considered the "beneficial holder" of the shares held for you in what is known as "street name." You are not the record holder of such shares. If this is the case, this joint proxy statement/prospectus has been forwarded to you by your broker, bank or other nominee. As the beneficial holder, unless your broker, bank or other nominee has discretionary authority over your shares, you generally have the right to direct your broker, bank or other nominee as to how to vote your shares. If you do not provide voting instructions, your shares will not be voted on any proposal, as your broker, bank or other nominee will not have discretionary voting authority with respect to any of the proposals described in this joint proxy statement/prospectus. This is often called a broker non-vote.

In connection with the US Ecology Special Meeting:

broker non-votes, if any, will have the same effect as a vote "AGAINST" the US Ecology Merger Agreement Proposal;

broker non-votes, if any, will have no effect on the outcome of the Holdco Stock Issuance Proposal;

broker non-votes, if any, will have the effect of a vote "AGAINST" the Holdco Charter Amendment Proposal; and

broker non-votes, if any, will have no effect on the US Ecology Adjournment Proposal.
Q:
What will happen if I fail to vote or I abstain from voting?

A:
For purposes of each of the US Ecology Special Meeting and the NRCG Special Meeting, an abstention occurs when a respective US Ecology stockholder or NRCG common stockholder either (1) attends the applicable special meeting in person and does not vote or (2) returns a proxy with an "abstain" vote.

An abstention will have the same effect as a vote "AGAINST" each of the US Ecology Merger Agreement Proposal, the Holdco Charter Amendment Proposal and the NRCG Merger Agreement Proposal, but will have no effect on the outcome of the Holdco Stock Issuance Proposal, the US Ecology Adjournment Proposal or the NRCG Adjournment Proposal.

In addition, a failure to vote altogether will have the same effect as a vote "AGAINST" each of the US Ecology Merger Agreement Proposal, the Holdco Charter Amendment Proposal and the NRCG Merger Agreement Proposal, but will have no effect on the outcome of the Holdco Stock Issuance Proposal, US Ecology Adjournment Proposal or the NRCG Adjournment Proposal.

Q:
What will happen if I return my proxy card without indicating how to vote?

A:
US Ecology Stockholders:    If you properly complete and sign your proxy card but do not indicate how your shares of ECOL Common Stock should be voted on a matter, the shares of ECOL Common Stock represented by your proxy will be voted as the US Ecology Board recommends and, therefore, "FOR" the US Ecology Merger Agreement Proposal, "FOR" the Holdco Stock Issuance Proposal, "FOR" the Holdco Charter Amendment Proposal and, if necessary, "FOR" the US Ecology Adjournment Proposal.

NRCG Common Stockholders:    If you properly complete and sign your proxy card but do not indicate how your shares of NRCG Common Stock should be voted on a matter, the shares of NRCG Common Stock represented by your proxy will be voted as the NRCG Board recommends and, therefore, "FOR" the NRCG Merger Agreement Proposal and "FOR" the NRCG Adjournment Proposal.

Q:
Can I change my vote or revoke my proxy after I have returned a proxy or voting instruction card?

A:
Yes.

If you are a holder of record of either ECOL Common Stock or NRCG Common Stock:    If you are a holder of record of either ECOL Common Stock or NRCG Common Stock, as applicable, you can change your vote or revoke your proxy at any time before your proxy is voted at your respective special meeting. You can do this in one of three ways:

timely delivering a signed written notice of revocation to the respective Secretary of US Ecology or NRCG, as applicable;

timely delivering a new, valid proxy for US Ecology or NRCG, as applicable, bearing a later date than your original proxy by submitting instructions through the Internet, by telephone or by mail as described on the applicable proxy card; or

attending your special meeting and voting in person, which will automatically cancel any proxy previously given, or you can revoke your proxy in person. Simply attending the US Ecology Special Meeting or the NRCG Special Meeting without voting will not revoke any proxy that you have previously given or change your vote.
Q:
What are the U.S. federal income tax consequences of the Mergers to U.S. holders of ECOL Common Stock, NRCG Common Stock, NRCG Warrants and NRCG Series A Preferred Stock?

A:
Consequences to U.S. holders of ECOL Common Stock, NRCG Common Stock and NRCG Series A Preferred Stock:    It is a condition to US Ecology's and NRCG's obligations to complete the Mergers that each of US Ecology and NRCG receive an opinion from Dechert LLP ("Dechert") or Jones Day to the effect that, in the case of US Ecology, the Mergers will each qualify as a "reorganization" within the meaning of Section 368(a) of the U.S. Internal Revenue Code of 1986, as amended (the "Code") or, alternatively, the Mergers together will be treated as an "exchange" described in Section 351 of the Code and, in the case of NRCG, the NRCG Merger will qualify as

Also in connection with the execution of the Merger Agreement, US Ecology entered into an Investor Agreement, dated June 23, 2019 (the "Investor Agreement"), with Holdco, the JFL Entities and, solely with respect to Section 4 thereof, NRCG, pursuant to which each of the JFL Entities agreed, among other things, to (1) a standstill for a period lasting until the earlier of (a) 120 days after the closing date of the Mergers and (b) the date that each such JFL Entity ceases to own any Holdco Common Stock and (2) lock-up restrictions for a period of 60 days from

Q:

However, the Mergers are subject to the satisfaction or waiver of certain conditions, and it is possible that factors outside the control of Holdco, NRCG and US Ecology could result in the Mergers being completed at a later time or not at all. On July 16, 2019, each of US Ecology and JFL-AIV Investors III-JA, L.P. (as the controlling stockholder of NRCG) received early termination of the waiting period under the Hart-Scott Rodino Antitrust Improvement Act of 1976, as amended, and the rules and regulations promulgated thereunder (the "HSR Act").

        It is a condition to US Ecology's and NRCG's obligations to complete the Mergers that each of US Ecology and NRCG receive an opinion from Dechert or Jones Day to the effect that, in the case of US Ecology, the Mergers will each qualify as a "reorganization" within the meaning of Section 368(a) of the Code or, alternatively, the Mergers together will be treated as an "exchange" described in Section 351 of the Code and, in the case of NRCG, the NRCG Merger will qualify as a "reorganization" within the meaning of Section 368(a) of the Code or, alternatively, the NRCG Merger, together with the ECOL Merger, will be treated as an "exchange" described in Section 351 of the Code. Assuming the Mergers are treated for U.S. federal income tax purposes as described above, a "U.S. holder" (as defined in "Material U.S. Federal Income Tax Consequences of the Mergers") of ECOL Common Stock, NRCG Common Stock or NRCG Series A Preferred Stock generally will not recognize any gain or loss for U.S. federal income tax purposes upon the exchange of shares of ECOL Common Stock, NRCG Common Stock or NRCG Series A Preferred Stock for shares of Holdco Common Stock in the ECOL Merger or the NRCG Merger, respectively, except with respect to cash received by NRCG stockholders in lieu of fractional shares of Holdco Common Stock.

        Assuming the NRCG Merger qualifies as a "reorganization" within the meaning of Section 368(a) of the Code, a U.S. holder of NRCG Warrants will not recognize gain or loss for U.S. federal income tax purposes upon the exchange of NRCG Warrants for Replacement Warrants. If the NRCG Merger does not qualify as a "reorganization" within the meaning of Section 368(a) of the Code, and, assuming the NRCG Merger, together with the ECOL Merger, will be treated as an "exchange" described in Section 351 of the Code, (1) a U.S. holder that exchanges solely NRCG Warrants for Replacement Warrants will recognize gain or loss equal to the difference between the fair market value of such Replacement Warrants and the U.S holder's tax basis in the NRCG Warrants surrendered therefor and (2) a U.S. holder that exchanges NRCG Warrants in addition to shares of NRCG Common Stock and/or NRCG Series A Preferred Stock will recognize gain (but not loss) equal to the lesser of (a) the sum of the fair market value of the Replacement Warrants and Holdco Common Stock received by such holder minus such U.S. holder's aggregate adjusted tax basis in the NRCG Warrants, NRCG

Common Stock and/or NRCG Series A Preferred Stock surrendered therefor and (b) the fair market value of the Replacement Warrants received by such U.S. holder.

Recommendation of the NRCG Board

        After careful consideration, the NRCG Board approved the Merger Agreement and determined that the Merger Agreement and the transactions contemplated thereby, including the Mergers, are fair, advisable and in the best interests of NRCG and its common stockholders. For more information regarding the factors considered by the NRCG Board in reaching its decision to approve the Merger Agreement, see the section entitled "The Mergers—NRCG's Reasons for the Mergers; Recommendation of the NRCG Board" of this joint proxy statement/prospectus.

Opinion of US Ecology's Financial Advisor

        In connection with the Mergers, US Ecology's financial advisor, BofA Securities, Inc. (referred to as "BofA Merrill Lynch"), delivered a written opinion, dated June 23, 2019, to the US Ecology Board as to the fairness, from a financial point of view and as of that date, to US Ecology of the NRCG Exchange Ratio provided for in the NRCG Merger in respect of shares of NRCG Common Stock. The full text of BofA Merrill Lynch's written opinion, dated June 23, 2019, which describes, among other things, the assumptions made, procedures followed, matters considered and limitations and qualifications on the review undertaken, is attached as Annex H to this joint proxy statement/prospectus and is incorporated by reference herein in its entirety. BofA Merrill Lynch delivered its opinion for the benefit and use of the US Ecology Board (in its capacity as such) in connection with and for purposes of its evaluation of the Mergers. BofA Merrill Lynch expressed no opinion or view as to any terms or other aspects or implications of the Mergers (other than the NRCG Exchange Ratio to the extent expressly specified in such opinion) and no opinion or view was expressed as to the relative merits of the Mergers in comparison to other strategies or transactions that might be available to US Ecology or in which US Ecology might engage or as to the underlying business decision of US Ecology to proceed with or effect the Mergers.

Opinion of NRCG's Financial Advisor

        The NRCG Board retained Evercore Group L.L.C. ("Evercore") to act as its financial advisor in connection with the Mergers. As part of this engagement, NRCG requested that Evercore evaluate the fairness, from a financial point of view, of the NRCG Exchange Ratio of 0.1960 shares of Holdco Common Stock for each share of NRCG Common Stock to be received by the holders of shares of NRCG Common Stock. At a meeting of the NRCG Board held on June 23, 2019, Evercore rendered to the NRCG Board its opinion to the effect that, as of that date and based upon and subject to the assumptions, limitations, qualifications and conditions described in Evercore's opinion, the NRCG Exchange Ratio of 0.1960 shares of Holdco Common Stock for each share of NRCG Common Stock to be received by the holders of shares of NRCG Common Stock in the NRCG Merger was fair, from a financial point of view, to such holders.

        The full text of the written opinion of Evercore, dated June 23, 2019, which sets forth, among other things, the procedures followed, assumptions made, matters considered and qualifications and limitations on the scope of review undertaken in rendering its opinion, is attached as Annex I to this joint proxy statement/prospectus and is incorporated herein by reference. NRCG encourages you to read Evercore's opinion carefully and in its entirety. Evercore's opinion was addressed to, and provided for the information and benefit of, the NRCG Board (in its capacity as such) in connection with its evaluation of the proposed Mergers. The opinion does not constitute a recommendation to the NRCG Board or to any other persons in respect of the Mergers, including as to how any holder of shares of NRCG Common Stock should vote or act in respect of the Mergers. Evercore's opinion does not address the relative merits of the Mergers as compared to other business or financial strategies that might be available to NRCG, nor does it address the underlying business decision of NRCG to engage in the Mergers.

Indebtedness Following the Mergers

        US Ecology is currently party to the Credit Agreement, dated as of April 18, 2017, by and among US Ecology, the lenders party thereto from time to time, Wells Fargo Bank, National Association, a national banking association, as administrative agent for the lenders, as swingline lender and as an issuing lender, and Bank of America, N.A., as an issuing lender (the "Existing Credit Agreement"). The Existing Credit Agreement provides for a $500 million revolving credit facility. US Ecology entered into the First Amendment, dated as of August 6, 2019, to amend the Existing Credit Facility to, among other things, permit a $400 million incremental term loan, and the First Amendment shall become effective upon the consummation of the Mergers. US Ecology is pursuing a Lender Joinder Agreement and Second Amendment which intends to amend the Credit Agreement to expand the capacity for incremental term loans by an additional $50 million and to incur a $450 million incremental term loan, which incremental term loan shall, together with borrowings under US Ecology's existing revolving credit facility, be used to refinance existing indebtedness of NRCG, to pay the fees and expenses incurred in connection with the Mergers and the transactions in connection therewith and to pay down a portion of the outstanding amount of the existing revolving credit facility.

Golden Parachute Compensation

        The Mergers do not constitute a "change of control" of US Ecology for purposes of any employment agreement, any equity grant agreement or any other compensatory arrangement of a named executive officer of US Ecology. As such, it is not anticipated that the Mergers will trigger any compensation, benefit or acceleration of vesting for any of US Ecology's named executive officers, in any case, that is based on or otherwise relates to the Mergers, whether based on a single-trigger arrangement or a double-trigger arrangement (e.g., amounts triggered by a change of control for which payment is conditioned upon the named executive officer's termination without cause or resignation for good reason, in either case, within a limited time period following the change of control). Accordingly,

Table of Contents

no amount is reportable in connection with the Mergers with respect to US Ecology's named executive officers pursuant to Item 402(t) of Regulation S-K.

Interests of US Ecology Directors and Executive Officers in the Mergers

        In considering the recommendation of the US Ecology Board, US Ecology stockholders should be aware that certain of US Ecology's executive officers and directors have interests in the Mergers that are different from, or in addition to, those of the US Ecology stockholders generally. These interests may present such executive officers and directors with actual or potential conflicts of interest. The US Ecology Board was aware of these interests during its deliberations on the merits of the Mergers and in deciding to recommend that US Ecology stockholders vote for the US Ecology proposals. For additional information on the interests of US Ecology's directors and officers in the Mergers, see the section entitled "The Mergers—Interests of US Ecology Directors and Executive Officers in the Mergers."

Interests of NRCG Directors and Executive Officers in the Mergers

        In considering the recommendation of the NRCG Board, NRCG common stockholders should be aware that certain of NRCG's directors and executive officers have interests in the Mergers that are different from, or in addition to, those of the NRCG common stockholders generally. These interests may present such directors and executive officers with actual or potential conflicts of interest. The NRCG Board was aware of these interests during its deliberations on the merits of the Mergers and in deciding to recommend that NRCG common stockholders vote for the NRCG proposals.

        These interests include the fact that: (1) certain NRCG non-employee directors are party to certain NRCG stock option agreements that provide for accelerated vesting in connection with the Mergers (estimated total intrinsic value for all NRCG non-employee directors of NRCG stock options based on the closing price per share of NRCG Common Stock on September 6, 2019, as reported on the NYSE American, and taking into account the $10.25 exercise price per share: $252,000) (see the section entitled "The Mergers—Interests of NRCG Directors and Executive Officers in the Mergers—NRCG Stock Options" for more information on the treatment of these NRCG stock options); (2) NRCG's executive officers are party to certain NRCG RSU agreements (estimated total fair market value for all NRCG executive officers of NRCG RSUs based on the closing price per share of NRCG Common Stock on September 6, 2019, as reported on the NYSE American: $4.5 million) (see the section entitled "The Mergers—Interests of NRCG Directors and Executive Officers in the Mergers—NRCG Restricted Stock Units" for more information on the treatment of NRCG RSUs; for the avoidance of doubt the NRCG RSUs held by the NRCG executive officers are being treated the same as all other NRCG RSUs in connection with the Mergers); and (3) NRCG's executive officers are party to certain agreements that provide for severance payments and the vesting of equity awards in connection with a qualifying termination of employment (estimated total value for all executive officers: $7.3 million) (see the sections entitled "The Mergers—Interests of NRCG Directors and Executive Officers in the Mergers—NRCG Employment Agreements" and "The Mergers—Interests of NRCG Directors and Executive Officers in the Mergers—Equity Acceleration Under Restricted Stock Unit Agreements" for more information on such agreements). For additional information on the interests of NRCG's directors and executive officers in the Mergers and the assumptions used in the quantifiable disclosure above, see the section entitled "The Mergers—Interests of NRCG Directors and Executive Officers in the Mergers," including the subsections to such section entitled "—Consideration for NRCG Common Stock at the Effective Time of the Mergers," "—NRCG Stock Options," "—NRCG Restricted Stock Units," "—NRCG Employment Agreements," "—Equity Acceleration Under Restricted Stock Unit Agreements," "—Employee Benefits" and "—Indemnification and Insurance."

Board of Directors of Holdco (the "Holdco Board"), Management and Certain Governance Matters Following the Mergers

        The US Ecology Board immediately prior to the Effective Time will be the Holdco Board following the Effective Time. The named executive officers of US Ecology immediately prior to the Effective Time shall be the named executive officers of Holdco following the Effective Time. The corporate headquarters for the combined company and its subsidiaries will be located at the corporate headquarters of US Ecology in Boise, Idaho.

Litigation Related to the Mergers

        Certain litigation is pending regarding the treatment of NRCG Series A Preferred Stock in the Mergers. For more information, see the section entitled "The Mergers—Litigation Related to the Mergers."

        US Ecology and NRCG, as applicable, have agreed to promptly advise the other party of any litigation commenced, or to its knowledge threatened, after the date of the Merger Agreement against such party or any of their respective directors by any stockholder of such party (on their own behalf or on behalf of such party) relating to the Merger Agreement or the transactions contemplated by the Merger Agreement (including the Mergers), and to keep the other party reasonably informed regarding any such litigation. US Ecology and NRCG, as applicable, have agreed to give the other party the opportunity to consult with such party regarding the defense or settlement of any such stockholder litigation, to consider the other party's views with respect to such stockholder litigation, and that no such settlement will be agreed to without the other party's prior written consent (which consent must not be unreasonably withheld, conditioned or delayed).

Regulatory Clearances Required for the Mergers

        US Ecology and NRCG have each agreed to take certain actions in order to obtain the regulatory clearances required to complete the Mergers. Required regulatory clearances include expiration or termination of the required waiting period under the HSR Act, following required notifications and review by either the Federal Trade Commission (the "FTC") or the Antitrust Division of the U.S. Department of Justice (the "Antitrust Division"). On July 8, 2019, each of US Ecology and JFL-AIV Investors III-JA, L.P. (as the controlling stockholder of NRCG) filed its notification under the HSR Act. On July 16, 2019, each of US Ecology and JFL-AIV Investors III-JA, L.P. (as the controlling stockholder of NRCG) received early termination of the waiting period under the HSR Act. Accordingly, the condition to the Mergers related to obtaining that clearance has been satisfied.

        The antitrust and competition laws of certain foreign countries often apply to transactions such as the Mergers, and notifications may be required when such laws are applicable. However, US Ecology and NRCG do not believe that any such foreign antitrust filings are required in connection with the Mergers, and accordingly, the obligations of US Ecology and NRCG to consummate the Mergers are not subject to conditions precedent related to any such foreign antitrust filings.

Amended and Restated Certificate of Incorporation of Holdco

        The Holdco Amended Charter will govern the rights of the stockholders of the combined company following the Effective Time and will be in substantially the same form attached as Annex E to this joint proxy statement/prospectus. Please see the section entitled "Comparison of Rights of US Ecology Stockholders, NRCG Stockholders and Holdco Stockholders" for a discussion of the Holdco Amended Charter. At the Effective Time, the Holdco Board also expects to adopt the Holdco Amended Bylaws, which will be in substantially the form attached hereto as Annex F.

Table of Contents

Completion of the Mergers

        US Ecology and NRCG are working to complete the Mergers as soon as practicable and expect the closing of the Mergers to occur in the fourth quarter of 2019. However, the Mergers are subject to the satisfaction or waiver of various conditions, and it is possible that factors outside the control of Holdco, US Ecology and NRCG could result in the Mergers being completed at a later time or not at all. There may be a substantial amount of time between the US Ecology Special Meeting, NRCG Special Meeting and the completion of the Mergers.

The Merger Agreement

Merger Consideration

        In the ECOL Merger, each share of ECOL Common Stock issued and outstanding immediately prior to the Effective Time (other than cancelled shares) will be converted into the right to receive one share of Holdco Common Stock. Outstanding equity awards of US Ecology will be exchanged for substantially similar equity awards of Holdco on a one-for-one basis. Each share of ECOL Common Stock that is held by US Ecology as treasury stock or that is owned by US Ecology, ECOL Merger Sub, or any of their respective direct or indirect wholly-owned subsidiaries immediately prior to the Effective Time will cease to be outstanding and will automatically be cancelled and will cease to exist, without any conversion thereof, and no consideration will be delivered in exchange therefor.

        In the NRCG Merger, each share of NRCG Common Stock issued and outstanding immediately prior to the Effective Time (other than cancelled shares) will be converted into the right to receive, and become exchangeable for, (1) 0.196 of a share of Holdco Common Stock for each share of NRCG Common Stock (2) any cash in lieu of fractional shares of Holdco Common Stock payable pursuant to the Merger Agreement and (3) any dividends or other distributions to which the holder thereof becomes entitled to upon the surrender of such shares of NRCG Common Stock in accordance with the Merger Agreement. Also in the NRCG Merger, each share of NRCG Series A Preferred Stock (other than shares owned by US Ecology, Holdco, Rooster Merger Sub, NRCG or any of their respective subsidiaries, which will cease to remain outstanding and will be canceled and cease to exist) will be converted into the right to receive, and become exchangeable for, (1) a whole number of shares of Holdco Common Stock equal to the product of (a) the number of shares of NRCG Common Stock that such share of NRCG Series A Preferred Stock could be converted into at the Effective Time (including Fundamental Change Additional Shares and Accumulated Dividends (each, as defined in the NRCG Series A Certificate of Designations)) multiplied by (b) the NRCG Exchange Ratio, (2) any cash in lieu of fractional shares of Holdco Common Stock payable pursuant to the Merger Agreement and (3) any dividends or other distributions to which the holder thereof becomes entitled to upon the surrender of such shares of NRCG Series A Preferred Stock in accordance with the Merger Agreement. Outstanding equity awards of NRCG will be exchanged for substantially similar equity awards of Holdco pursuant to the mechanics set forth in the Merger Agreement. In the NRCG Merger, each share of NRCG Common Stock that is held by NRCG as treasury stock or that is owned by NRCG, Rooster Merger Sub or any other subsidiary of US Ecology or NRCG immediately prior to the Effective Time will cease to be outstanding and will automatically be cancelled and will cease to exist, without any conversion thereof, and no consideration will be delivered in exchange therefor.

        At the Effective Time, US Ecology shall cause all shares of Holdco Common Stock that are issued and outstanding immediately prior to the Effective Time to be surrendered and cancelled and cease to exist, with no consideration delivered in exchange therefor.

No Solicitation of Takeover Proposal Proposals

        The Merger Agreement prohibits US Ecology, NRCG and their respective subsidiaries from soliciting or engaging in discussions or negotiations with a third-party with respect to a proposal for a

23


Table of Contents

competing transaction, including the acquisition of a significant interest in ECOL Common Stock or its assets or NRCG Common Stock or its assets. However, the respective board of directors of each of US Ecology and NRCG may, subject to certain conditions, change its recommendation to its respective stockholders, terminate the Merger Agreement and enter into an agreement with respect to a superior alternative proposal if the respective board of directors of US Ecology or NRCG determines in its reasonable good faith judgment, after consultation with its outside legal counsel and financial advisor, that the alternative proposal is more favorable from a financial point of view to US Ecology's or NRCG's stockholders, as applicable, than the transactions contemplated by the Merger Agreement.

Conditions to Completion of the Mergers

        Each party's obligation to consummate the Mergers is conditioned upon the satisfaction or waiver of each of the following:

        In addition, the obligations of each of US Ecology, Holdco, ECOL Merger Sub and Rooster Merger Sub on the one hand, and NRCG, on the other hand, to consummate the Mergers is conditioned upon the satisfaction or waiver of each of the following:

Table of Contents

Termination of the Merger Agreement

        US Ecology and NRCG may mutually agree to terminate the Merger Agreement at any time. Either US Ecology or NRCG may also terminate the Merger Agreement if the Mergers are not completed by December 23, 2019, unless extended pursuant to the Merger Agreement, and the failure of the Mergers to be consummated by such date is not caused by the terminating party's breach of any representation, warranty, covenant, or agreement set forth in the Merger Agreement. See the section entitled "The Merger Agreement—Termination of the Merger Agreement" for a discussion of these and other rights of each of US Ecology and NRCG to terminate the Merger Agreement.

Expenses and Termination Fees

        Generally, all fees and expenses incurred in connection with the Merger Agreement and the transactions contemplated by the Merger Agreement will be paid by the party incurring those expenses, subject to the specific exceptions discussed in this joint proxy statement/prospectus where (1) US Ecology may be required to pay a termination fee of $60 million to NRCG and (2) NRCG may be required to pay a termination fee of $35 million to US Ecology. In addition, US Ecology may be required to pay NRCG an expense reimbursement payment in the amount of up to $10 million if the US Ecology stockholder proposals are not approved at the US Ecology Special Meeting. See the section entitled "The Merger Agreement—Expenses and Termination Fees; Liability for Breach" of this joint proxy statement/prospectus for a discussion of the circumstances under which such termination fee and expense reimbursement payment will be required to be paid.

Support Agreement, Investor Agreement and Registration Rights Agreement

        Simultaneously with the execution of the Merger Agreement, US Ecology entered into the Support Agreement with Holdco, Rooster Merger Sub and the JFL Entities. As of each of the date of the Merger Agreement and the NRCG Record Date, the JFL Entities were the registered holders of approximately 66% of the currently issued and outstanding NRCG Common Stock. Pursuant to the Support Agreement, the JFL Entities have agreed, among other things, to vote all of their shares of NRCG Common Stock in favor of the adoption of the Merger Agreement. As a result, and subject to the Support Agreement, the approval of the NRCG Merger Agreement Proposal is effectively assured. The Support Agreement is attached hereto as Annex B.

        Also in connection with the execution of the Merger Agreement, US Ecology entered into the Investor Agreement with Holdco, the JFL Entities and, solely with respect to Section 4 thereof, NRCG, pursuant to which each of the JFL Entities agreed, among other things, to (1) a standstill for a period lasting until the earlier of (a) 120 days after the closing date of the Mergers and (b) the date the JFL Entities cease to own any Holdco Common Stock and (2) lock-up restrictions for a period of 60 days from the closing of the Mergers with respect to 1/3 of the shares held by the JFL Entities at closing of the Mergers, 90 days from the closing of the Mergers with respect to 1/3 of the shares held by the JFL Entities at closing of the Mergers and 120 days from the closing of the Mergers with respect to 1/3 of the shares held by the JFL Entities immediately following closing of the Mergers. The Investor Agreement is attached hereto as Annex C.

        In addition, in connection with the execution of the Merger Agreement, US Ecology entered into the Registration Rights Agreement with Holdco and the JFL Entities, pursuant to which US Ecology granted the JFL Entities certain demand and piggyback registration rights with respect to the registration of the Registrable Securities. The Registration Rights Agreement is attached hereto as Annex D.

        For additional information regarding the Support Agreement, Investor Agreement and Registration Rights Agreement, see the section entitled "The Mergers—Support Agreement, Investor Agreement and Registration Rights Agreement."

Accounting Treatment

        Holdco will prepare its financial statements in accordance with accounting principles generally accepted in the United States ("GAAP"). US Ecology will be treated as the acquirer for accounting purposes.

Appraisal Rights

        Under the DGCL, holders of NRCG Common Stock and ECOL Common Stock are not entitled to appraisal rights in connection with the Mergers. Under the DGCL and the Merger Agreement, holders of NRCG Series A Preferred Stock will be entitled to appraisal rights in connection with the NRCG Merger. See the section entitled "Appraisal Rights" for more information regarding appraisal rights to which holders of NRCG Series A Preferred Stock will be entitled.

Risk Factors

        In deciding how to vote your shares of ECOL Common Stock or NRCG Common Stock, you should read carefully this entire joint proxy statement/prospectus, including the documents incorporated by reference herein and the annexes and exhibits hereto, and in particular, you should read the "Risk Factors" section of this joint proxy statement/prospectus.

Listing of Holdco Common Stock; De-Listing and Deregistration of ECOL Common Stock and NRCG Common Stock and Warrants

        It is a condition to the completion of the Mergers that the shares of Holdco Common Stock to be issued to US Ecology stockholders and NRCG stockholders pursuant to the Mergers be authorized for listing on Nasdaq, subject to official notice of issuance, and US Ecology and NRCG have agreed to use their reasonable best efforts to cause such shares (including shares of Holdco Common Stock reserved for issuance upon exercise of Holdco stock options and the Replacement Warrants) to be listed on Nasdaq. Upon completion of the Mergers, shares of ECOL Common Stock currently listed on Nasdaq and shares of NRCG Common Stock and NRCG Warrants currently listed on the NYSE American will cease to be listed on their respective stock exchanges and will be subsequently deregistered under the Exchange Act. Immediately following the consummation of the Mergers, Holdco will be renamed "US Ecology, Inc." and shares of Holdco Common Stock will be listed on Nasdaq under the symbol "ECOL." The parties to the Merger Agreement intend for Holdco to list the Replacement Warrants on Nasdaq in connection with the closing of the Mergers under the symbol "ECOLW."

Comparison of Rights of US Ecology Stockholders, NRCG Stockholders and Holdco Stockholders

        US Ecology stockholders and NRCG stockholders receiving merger consideration will have rights different from their rights prior to the Effective Time once they become stockholders of Holdco due to differences between the governing corporate documents of US Ecology and NRCG, respectively, and the proposed governing corporate documents of Holdco. The Holdco Amended Charter will be substantially identical to the existing amended and restated certificate of incorporation of US Ecology (the "US Ecology Charter"), with the addition of certain provisions to adopt ownership qualifications, restrictions, requirements and procedures to facilitate Holdco's compliance with the U.S. citizenship requirements of the Jones Act. Please see the section entitled "Comparison of Rights of US Ecology Stockholders, NRCG Stockholders and Holdco Stockholders" for a discussion of these differences.

The US Ecology Special Meeting

        The US Ecology Special Meeting is scheduled to be held at the offices of US Ecology located at 101 S. Capitol Blvd., Suite 1000, Boise, Idaho 83702, on October 23, 2019 at 10:00 a.m., local time, subject to any adjournments or postponements thereof. The US Ecology Special Meeting is being held in order for US Ecology stockholders to consider and vote on:

        Only holders of record of ECOL Common Stock at the close of business on the US Ecology Record Date, are entitled to notice of, and to vote at, the US Ecology Special Meeting or any adjournments or postponements thereof. At the close of business on the US Ecology Record Date, 22,080,545 shares of ECOL Common Stock were issued and outstanding, less than 1% of which were held by US Ecology's directors and executive officers. US Ecology currently expects that US Ecology's directors and executive officers will vote their shares in favor of each proposal being submitted to a vote of the US Ecology stockholders at the US Ecology Special Meeting, although no director or executive officer has entered into any agreement obligating him or her to do so.

        You may cast one vote for each share of ECOL Common Stock you own. The US Ecology Merger Agreement Proposal and the Holdco Charter Amendment Proposal each require the affirmative vote of the holders of a majority of the issued and outstanding shares of ECOL Common Stock entitled to

27

vote on the proposal. The Holdco Stock Issuance Proposal and the US Ecology Adjournment Proposal each require the affirmative vote of the majority of all votes cast at the US Ecology Special Meeting and entitled to vote thereon. Failures to vote, abstentions and broker non-votes will have the effect of a vote against the US Ecology Merger Agreement Proposal and the Holdco Charter Amendment Proposal. Failures to vote, abstentions and broker non-votes will have no effect on the outcome of the Holdco Stock Issuance Proposal or the US Ecology Adjournment Proposal. If a quorum is not present, the US Ecology Special Meeting may be adjourned by the chairman of the US Ecology Special Meeting or the holders of a majority of shares of the ECOL Common Stock entitled to vote who are present, in person or by proxy, to another place, date, or time without notice other than announcement at the meeting, until a quorum shall be present or represented.

The NRCG Special Meeting

        The NRCG Special Meeting is scheduled to be held at 717 Texas, Suite 3300, Houston, Texas 77002, on October 22, 2019 at 9:00 a.m., local time, subject to any adjournments or postponements thereof. The NRCG Special Meeting is being held in order for NRCG common stockholders to consider and vote on:

        Only holders of record of NRCG Common Stock at the close of business on the NRCG Record Date are entitled to vote at the NRCG Special Meeting or any adjournments or postponements thereof. At the close of business on the NRCG Record Date, 38,050,385 shares of NRCG Common Stock were issued and outstanding, approximately 70% of which were directly held by NRCG's directors, executive officers and the JFL Entities.

        You may cast one vote for each share of NRCG Common Stock you own. Assuming a quorum is present, the approval of the NRCG Merger Agreement Proposal requires the affirmative vote of the holders of a majority of the issued and outstanding shares of NRCG Common Stock entitled to vote on the proposal and the approval of the NRCG Adjournment Proposal requires the affirmative vote of the majority of all votes cast at the NRCG Special Meeting and entitled to vote thereon. Failures to vote, abstentions and broker non-votes will have the effect of a vote against the NRCG Merger Agreement Proposal. Failures to vote, abstentions and broker non-votes will have no effect on the outcome of the NRCG Adjournment Proposal.

        If a quorum is not present, the NRCG Special Meeting may be adjourned by the chairman of the NRCG Special Meeting until a quorum shall be present or represented, to reconvene at the same or another place, and notice need not be given of any such adjourned meeting if the time and place thereof are announced at the meeting at which the adjournment is taken.

III ("HCAC"), acquired NRC Group Holdings, LLC ("NRC Group") pursuant to that certain Purchase Agreement, dated as of June 25, 2018, and amended on July 12, 2018 (the "2018 Purchase Agreement"), by and between JFL Partners and NRCG (f/k/a Hennessey Capital Acquisition Corp.).

COMPARATIVE HISTORICAL AND UNAUDITED PRO FORMA PER SHARE DATA

        Presented below are US Ecology's and NRCG's historical per share data for the six months ended June 30, 2019 and the year ended December 31, 2018. Holdco unaudited pro forma combined per share data for the six months ended June 30, 2019 and the year ended December 31, 2018 and NRCG unaudited pro forma equivalent per share data for the six months ended June 30, 2019 and the year ended December 31, 2018. This information should be read together with the consolidated financial statements of US Ecology and NRCG and the related notes that are incorporated by reference in this joint proxy statement/prospectus and with the unaudited pro forma combined financial data included in the section entitled "Unaudited Pro Forma Condensed Combined Financial Statements" of this joint proxy statement/prospectus. The pro forma information is presented for illustrative purposes only and is not necessarily indicative of the operating results or financial position that would have occurred if the Mergers had been completed as of the beginning of the periods presented, nor is it necessarily indicative of the future operating results or financial position of the combined company. The historical book value per share is computed by dividing total stockholders' equity (deficit) by the number of shares of common stock issued and outstanding at the end of the period. The pro forma income (loss) per share of the combined company is computed by dividing the pro forma income (loss) by the pro forma weighted average number of shares issued and outstanding. The pro forma book value per share of the combined company is computed by dividing total pro forma stockholders' equity (deficit) by the pro forma number of shares of common stock issued and outstanding at the end of the period. The NRCG unaudited pro forma equivalent per share financial information for each is computed by multiplying the Holdco unaudited pro forma combined per share amounts by the respective exchange ratio (0.196 shares of Holdco Common Stock for each share of NRCG Common Stock).

COMPARATIVE STOCK PRICE DATA AND DIVIDENDS

        Shares of ECOL Common Stock are listed on Nasdaq under the symbol "ECOL." Shares of NRCG Common Stock are listed on the NYSE American under the symbol "NRCG." The following table presents the closing price per share of ECOL Common Stock and NRCG Common Stock and the implied value of the ECOL Common Stock merger consideration and the NRCG Common Stock merger consideration on June 21, 2019, the last full trading day before public announcement that US Ecology and NRCG had entered into the Merger Agreement, and September 6, 2019, the last practicable trading day before the date of this joint proxy statement/prospectus.

  $ 61.74   $ 11.93   $ 61.74   $ 12.10  

(1)
The implied per share value of ECOL Common Stock merger consideration has been determined by multiplying the market price of one share of ECOL Common Stock on each of the dates by the US Ecology exchange ratio of 1.0 shares of Holdco Common Stock for each share of ECOL Common Stock.

(2)
The implied per share value of NRCG Common Stock merger consideration has been determined by multiplying the market price of one share of ECOL Common Stock on each of the dates by the NRCG Exchange Ratio of 0.196 of a share of Holdco Common Stock for each share of NRCG Common Stock.

        The market prices of ECOL Common Stock and NRCG Common Stock have fluctuated since the date of the announcement of the Merger Agreement and may continue to fluctuate from the date of this joint proxy statement/prospectus to the dates of the US Ecology Special Meeting and NRCG Special Meeting and the date the Mergers are completed. US Ecology stockholders and NRCG stockholders will be entitled to receive a fixed number of shares of Holdco Common Stock in the ECOL Merger and the NRCG Merger, respectively, rather than a number of shares of Holdco Common Stock with a particular fixed market value. Because the exchange ratios will not be adjusted for changes in the market price of either ECOL Common Stock or NRCG Common Stock, the market value of Holdco Common Stock that US Ecology stockholders and NRCG stockholders will have the right to receive pursuant to the Merger Agreement may vary significantly from the market value of the Holdco Common Stock that US Ecology stockholders and NRCG stockholders would receive if the Mergers were completed on the date of this joint proxy statement/prospectus. See the section entitled "Risk Factors—Risks Factors Relating to the Mergers—US Ecology stockholders and NRCG stockholders cannot be sure of the value of the merger consideration they will receive." No assurance can be given concerning the market prices of ECOL Common Stock or NRCG Common Stock before completion of the Mergers or of Holdco Common Stock after completion of the Mergers. We urge you to obtain current market quotations for ECOL Common Stock and NRCG Common Stock and to review carefully the other information contained in this joint proxy statement/prospectus or incorporated by reference into this joint proxy statement/prospectus prior to voting your shares. For more information, see the section entitled "Where You Can Find More Information."

        As of September 6, 2019, the last date before the date of this joint proxy statement/prospectus for which it was practicable to obtain this information, there were 22,080,545 shares of ECOL Common Stock outstanding and approximately 194 holders of record of ECOL Common Stock, and 38,050,385 shares of NRCG Common Stock outstanding and approximately 44 holders of record of NRCG Common Stock.

Dividends

        US Ecology has paid a quarterly dividend of $0.18 per share of ECOL Common Stock for the past several years. US Ecology most recently paid a cash dividend on July 1, 2019 of $0.18 per share. US Ecology currently expects to continue to pay quarterly cash dividends, although they remain subject to determination and declaration by the US Ecology Board. The payment of future dividends, if any, will be based on several factors, including US Ecology's financial performance, outlook and liquidity.

        Upon completion of the Mergers, any future determination regarding dividend or distribution payments will be at the discretion of the Holdco Board, subject to applicable limitations under the DGCL.

RISK FACTORS

        In addition to the other information included and incorporated by reference in this joint proxy statement/prospectus, including the matters addressed in the section entitled "Cautionary Statement Regarding Forward-Looking Statements," you should carefully consider the following risks before deciding how to vote. In addition, you should read and consider the risks associated with each of the businesses of NRCG and US Ecology because these risks will also affect the combined company. These risks can be found in the Annual Report on Form 10-K for the fiscal year ended December 31, 2018 filed on March 25, 2019, in the case of NRCG, and in the Annual Report on Form 10-K for the fiscal year ended December 31, 2018 filed on February 28, 2019, and any amendments thereto, in the case of US Ecology, as such risks may be updated or supplemented in each company's subsequently filed Quarterly Reports on Form 10-Q or Current Reports on Form 8-K, which are incorporated by reference into this joint proxy statement/prospectus. You should also read and consider the other information in this joint proxy statement/prospectus and the other documents incorporated by reference in this joint proxy statement/prospectus. See the section entitled "Where You Can Find More Information" of this joint proxy statement/prospectus.

Risk Factors Relating to the Mergers

US Ecology stockholders and NRCG stockholders cannot be sure of the value of the merger consideration they will receive.

        US Ecology stockholders and NRCG stockholders will be entitled to receive a fixed number of shares of Holdco Common Stock in the ECOL Merger and the NRCG Merger, respectively, rather than a number of shares of Holdco Common Stock with a particular fixed market value. The market values of ECOL Common Stock and NRCG Common Stock at the Effective Time may vary significantly from their prices on the date prior to the date the Merger Agreement was executed, the date of this joint proxy statement/prospectus or the date on which US Ecology stockholders and NRCG common stockholders vote on the proposal to adopt the Merger Agreement. Because the exchange ratios are fixed and will not be adjusted to reflect any changes in the market prices of ECOL Common Stock or NRCG Common Stock, the market value of the Holdco Common Stock issued in the ECOL Merger or the NRCG Merger, as applicable, and the ECOL Common Stock and NRCG Common Stock surrendered in the ECOL Merger and the NRCG Merger, respectively, may be higher or lower than the values of these shares on earlier dates. All of the merger consideration to be received by US Ecology stockholders and NRCG stockholders will be Holdco Common Stock (other than any cash in lieu of fractional shares received by NRCG stockholders). At the time of the special meetings, US Ecology stockholders and NRCG stockholders will not know or be able to determine the value of the Holdco Common Stock they may receive upon completion of the Mergers. Changes in the market prices of ECOL Common Stock and NRCG Common Stock may result from a variety of factors that are beyond the control of US Ecology or NRCG, including changes in their respective businesses, operations and prospects, regulatory considerations, governmental actions, and legal proceedings and other developments. Market assessments of the benefits of the Mergers, the likelihood that the Mergers will be completed and general and industry-specific market and economic conditions may also have an effect on the market price of ECOL Common Stock and NRCG Common Stock. Changes in market prices of ECOL Common Stock and NRCG Common Stock may also be caused by fluctuations and developments affecting industry-specific and general economic and market conditions and may have an adverse effect on ECOL Common Stock and NRCG Common Stock prior to the consummation of the Mergers.

        Neither US Ecology nor NRCG is permitted to terminate the Merger Agreement solely because of changes in the market prices of either party's common stock. In addition, the market values of ECOL Common Stock and NRCG Common Stock may vary significantly from the date of the special meetings to the date of the completion of the Mergers. You are urged to obtain up-to-date prices for ECOL Common Stock and NRCG Common Stock. There is no assurance that the Mergers will be completed,

36


Table of Contents

that there will not be a delay in the completion of the Mergers or that all or any of the anticipated benefits of the Mergers will be obtained.

        US Ecology and NRCG are working to complete the transactions as promptly as practicable. The parties currently expect that the Mergers will be completed during the fourth quarter of 2019, subject to the satisfaction or waiver of the conditions to the closing of the Mergers. Moreover, during the period between the special meetings and the closing of the Mergers, events, conditions or circumstances could arise that could have a material impact or effect on US Ecology, NRCG or the industries in which they operate.

The market price for Holdco Common Stock may be affected by factors different from those that historically have affected ECOL Common Stock and NRCG Common Stock.

        Upon completion of the Mergers, holders of shares of ECOL Common Stock (other than any shares held in treasury), holders of shares of NRCG Common Stock (other than any shares held in treasury) and holders of NRCG Series A Preferred Stock will become holders of shares of Holdco Common Stock. US Ecology and NRCG each have businesses that differ from each other. Accordingly, the results of operations of Holdco will be affected by some factors that are different from those currently affecting the results of operations of each of US Ecology and NRCG. For a discussion of the businesses of US Ecology and NRCG and of some important factors to consider in connection with those businesses, see the documents incorporated by reference in this joint proxy statement/prospectus and referred to under "Where You Can Find More Information" of this joint proxy statement/prospectus.

Any delay in completing the Mergers may reduce or eliminate the benefits expected to be achieved thereunder.

        The Mergers are subject to a number of conditions beyond US Ecology's and NRCG's control that may prevent, delay or otherwise materially adversely affect their completion. We cannot predict whether and when these other conditions will be satisfied. Any delay in completing the Mergers could cause the combined company not to realize, or to be delayed in realizing, some or all of the synergies and other benefits that the parties expect to achieve if the Mergers are successfully completed within their expected time frame. See the section entitled "The Merger Agreement—Conditions to Completion of the Mergers" in this joint proxy statement/prospectus.

US Ecology and NRCG will be subject to business uncertainties while the Mergers are pending, which may cause a loss of customers, suppliers, management personnel and other key employees that could adversely affect the future business and operations of the combined company.

        Uncertainty about the completion or effect of the Mergers may affect the relationship between US Ecology and NRCG and their respective customers and suppliers and may have an adverse effect on US Ecology and/or NRCG, and consequently on the combined company. These uncertainties may cause customers, suppliers and others that deal with the parties to seek to change existing business relationships with them and to delay or defer decisions concerning US Ecology or NRCG. Changes to existing business relationships, including termination or modification, could negatively affect each of US Ecology's and NRCG's revenues, earnings and cash flow, as well as the market price of its common stock.

        US Ecology and NRCG are dependent on the experience and industry knowledge of their respective officers and other key employees to execute their business plans. The combined company's success after the Mergers will depend in part upon the ability of US Ecology and NRCG to retain management personnel and other key employees. Current and prospective employees of US Ecology and NRCG may experience uncertainty about their roles within the combined company following the Mergers, which may have an adverse effect on the ability of each of US Ecology and NRCG to attract

37


Table of Contents

or retain management personnel and other key employees. If key employees depart because of issues related to the uncertainty and difficulty of integration or a desire not to remain with the businesses, the combined company's business following the consummation of the Mergers could be negatively impacted. Accordingly, no assurance can be given that the combined company will be able to attract or retain management personnel and other key employees of US Ecology and NRCG to the same extent that US Ecology and NRCG have previously been able to attract or retain their own employees. A failure by US Ecology, NRCG or, following the completion of the Mergers, the combined company to attract and retain management personnel and other key employees during the period prior to or after the completion of the Mergers could have a negative impact on their respective businesses.

US Ecology and NRCG will be subject to certain contractual restrictions while the Mergers are pending.

        The Merger Agreement restricts each of US Ecology and NRCG from making certain acquisitions and divestitures, issuing or selling securities other than pursuant to certain specified exceptions, and taking other specified actions, if outside the ordinary course of business consistent with past practice, until the earlier of the completion of the Mergers or the termination of the Merger Agreement without the consent of the other party. These restrictions may prevent US Ecology and/or NRCG from pursuing attractive business opportunities that may arise prior to the completion of the Mergers and could have the effect of delaying or preventing other strategic transactions. Adverse effects arising from the pendency of the Mergers could be exacerbated by any delays in consummation of the Mergers or the termination of the Merger Agreement. See the section entitled "The Merger Agreement—Conduct of Business Pending the Effective Time" of this joint proxy statement/prospectus.

Third parties may terminate or alter existing contracts or relationships with US Ecology or NRCG.

        NRCG has contracts with customers, suppliers, landlords, licensors, joint venture partners and other business partners which may require NRCG to obtain consent from these other parties in connection with the Mergers. If these consents cannot be obtained, the counterparties to these contracts and other third parties with which NRCG currently has relationships may have the ability to terminate, reduce the scope of or otherwise materially adversely alter their relationships with NRCG in anticipation of the Mergers, or with the combined company following the Mergers. The pursuit of such rights may result in NRCG or the combined company suffering a loss of potential future revenue or incurring liabilities in connection with a breach of such agreements and may lose rights that are material to its business. Any such disruptions could limit the combined company's ability to achieve the anticipated benefits of the Mergers. The adverse effect of such disruptions could also be exacerbated by a delay in the completion of the Mergers or the termination of the Merger Agreement.

NRCG or US Ecology may waive one or more of the closing conditions without re-soliciting stockholder approval.

        NRCG or US Ecology may determine to waive, in whole or in part, one or more of the conditions to its obligations to consummate the Mergers. NRCG or US Ecology currently expect to evaluate the materiality of any waiver and its effect on NRCG stockholders or US Ecology stockholders, as applicable, in light of the facts and circumstances at the time to determine whether any amendment of this joint proxy statement/prospectus or any re-solicitation of proxies or voting cards is required in light of such waiver. Any determination whether to waive any condition to the Mergers or as to re-soliciting stockholder approval or amending this joint proxy statement/prospectus as a result of a waiver will be made by NRCG or US Ecology, as applicable, at the time of such waiver based on the facts and circumstances as they exist at that time.

The Merger Agreement may be terminated in accordance with its terms and the Mergers may not be completed.

        If the Mergers are not completed by December 23, 2019 (or such later date if extended pursuant to the Merger Agreement), either NRCG or US Ecology may choose not to proceed with the Mergers and to terminate the Merger Agreement, and the parties can mutually decide to terminate the Merger Agreement at any time prior to the consummation of the Mergers, before or after the required NRCG and US Ecology stockholder approvals. In addition, NRCG or US Ecology may elect to terminate the Merger Agreement in certain other circumstances. If the Merger Agreement is terminated, NRCG and US Ecology may incur substantial fees in connection with termination of the Merger Agreement, will not recognize the anticipated benefits of the Mergers and each party may be adversely affected by a number of factors including the inability to pursue other beneficial opportunities and the focus of their respective managements on the Mergers for an extended period of time rather than on management opportunities or other issues. The market price of NRCG Common Stock and/or ECOL Common Stock might decline as a result of any such failures to the extent that the current market prices reflect a market assumption that the Mergers will be completed. See the section entitled "The Merger Agreement—Termination of the Merger Agreement" of this joint proxy statement/prospectus.

US Ecology and NRCG will incur significant transaction costs in connection with the Mergers.

        US Ecology and NRCG have incurred and expect to incur a number of nonrecurring costs associated with the Mergers. These costs and expenses include financial advisory, legal, accounting and other advisory fees and expenses, reorganization and restructuring costs, employee benefit-related expenses, public company filing fees and other regulatory expenses, printing expenses and other related charges. Some of these costs are payable by US Ecology and NRCG regardless of whether the Mergers are completed.

Lawsuits have been and may be filed against US Ecology and NRCG challenging the Mergers and an adverse ruling may prevent the Mergers from being completed.

        US Ecology and NRCG have been and may be targets of lawsuits, including securities class action lawsuits, derivative lawsuits and lawsuits from holders of NRCG capital stock, which could result in substantial costs and may delay or prevent the Mergers from being completed. Securities class action lawsuits and derivative lawsuits are often brought against public companies that have entered into merger agreements. Even if the lawsuits are without merit, defending against these claims can result in substantial costs and divert management time and resources. An adverse judgment could result in monetary damages, which could have a negative impact on US Ecology's and NRCG's respective liquidity and financial condition. Additionally, if a plaintiff is successful in obtaining an injunction prohibiting the closing, then that injunction may delay or prevent the Mergers from being consummated, which may adversely affect US Ecology's and NRCG's respective business, financial position and results of operation. One of the conditions to the closing of the Mergers is the absence of any laws or orders, whether temporary, preliminary, or permanent, that make illegal, enjoin, or otherwise prohibit consummation of the Mergers, the Holdco stock issuance, or the other transactions contemplated by the Merger Agreement. Consequently, if a settlement or other resolution is not reached in any such lawsuits and the plaintiffs secure injunctive or other relief prohibiting, delaying or otherwise adversely affecting the parties' ability to complete the Mergers, then such injunctive or other relief may prevent the Mergers from becoming effective within the expected time frame or at all. See the section entitled "The Mergers—Litigation Related to the Mergers" for more information, including with respect to certain litigation that is pending in connection with the Mergers.

Failure to complete the Mergers could negatively impact the stock prices and the future business and financial results of US Ecology and NRCG.

        Completion of the Mergers is not assured and is subject to risks, including the risks that approval of the transactions by US Ecology stockholders and NRCG common stockholders or by governmental entities will not be obtained or that certain other closing conditions will not be satisfied. If the Mergers are not completed, the ongoing businesses and financial results of US Ecology and/or NRCG may be adversely affected and US Ecology and/or NRCG will be subject to several risks, including the following:

        If the Mergers are not completed, US Ecology and NRCG cannot assure their respective stockholders that these risks will not materialize and will not materially adversely affect the businesses, financial results and stock prices of US Ecology or NRCG.

The Merger Agreement contains provisions that could discourage a potential competing acquirer of either US Ecology or NRCG.

        The Merger Agreement contains "no shop" provisions that generally restrict each of US Ecology's and NRCG's ability to solicit, initiate or knowingly encourage and induce, or take any other action designed to facilitate competing third-party proposals relating to a merger, reorganization or consolidation of the company or an acquisition of US Ecology or NRCG's stock or assets. In addition, each of US Ecology and NRCG generally has an opportunity to offer to modify the terms of the Merger Agreement in response to any competing acquisition proposals before the board of directors of the company that has received a third-party proposal may withdraw or qualify its recommendation with respect to the Mergers. In addition, under specified circumstances, (1) US Ecology may be required to pay a termination fee of $60 million to NRCG and (2) NRCG may be required to pay a termination fee of $35 million to US Ecology. In addition, US Ecology may be required to pay NRCG an expense reimbursement payment in the amount up to $10 million. See the sections entitled "The Merger Agreement—No Solicitation of Takeover Proposals," "The Merger Agreement—Termination of the Merger Agreement" and "The Merger Agreement—Expenses and Termination Fees; Liability for Breach" of this joint proxy statement/prospectus for a discussion of these provisions.

        These provisions could discourage a potential third-party acquirer that might have an interest in acquiring all or a significant portion of US Ecology or NRCG from considering or proposing that acquisition, even if it were prepared to pay consideration with a higher per share cash or market value than the market value of Holdco shares to be received in the Mergers or might result in a potential third-party acquirer proposing to pay a lower price to the stockholders than it might otherwise have proposed to pay because of the added expense of the termination fees and/or expense reimbursement amount that may become payable in certain circumstances.

        If the Merger Agreement is terminated and either US Ecology or NRCG determines to seek another business combination, it may not be able to negotiate a transaction with another party on terms comparable to, or better than, the terms of the Mergers.

Executive officers and directors of each of US Ecology and NRCG have certain interests in the Mergers that are different from, or in addition to, the interests of US Ecology stockholders and NRCG stockholders generally.

        US Ecology's executive officers and NRCG's executive officers negotiated the terms of the Merger Agreement. Certain directors and executive officers of US Ecology have interests in the Mergers that are in addition to their interests as US Ecology stockholders generally. For executive officers, these interests include continued employment with the combined company. For additional information on these interests, see the sections entitled "The Mergers—Interests of US Ecology Directors and Executive Officers in the Mergers."

        Immediately following the Effective Time, Holdco Board will be comprised of nine members, consisting of: Jeffrey R. Feeler, the current chairman of the US Ecology Board and president and chief executive officer of US Ecology, Joe F. Colvin, Katina Dorton, Glenn A. Eisenberg, Daniel Fox, Ronald C. Keating, Stephen A. Romano, John T. Sahlberg and Melanie Steiner. Each of these individuals is currently a director on the US Ecology Board.

        Certain directors and executive officers of NRCG have interests in the Mergers that are in addition to their interests as NRCG stockholders generally. For executive officers, these interests include continued employment with the combined company, potential severance payments and the vesting of equity awards in connection with a qualifying termination of employment. For certain non-employee directors, these interests include the treatment in the Mergers of NRCG stock option awards. The NRCG Board was aware of these interests at the time it approved the Mergers and the transactions contemplated by the Merger Agreement. These interests, including the continued employment of certain executive officers of NRCG by the combined company, may cause NRCG's directors and executive officers to view the proposal to adopt the Merger Agreement differently than you may view it. See the sections entitled "The Merger Agreement—Employee Benefits Matters" and "The Mergers—Interests of NRCG Directors and Executive Officers in the Mergers—Employee Benefits" in this joint proxy statement/prospectus for more information.

Current US Ecology stockholders and NRCG stockholders will have a reduced ownership and voting interest in Holdco after the Mergers compared to their respective interest in NRCG or US Ecology.

        Current holders of ECOL Common Stock and NRCG Common Stock have the right to vote in the election of the board of directors and on other matters affecting US Ecology and NRCG, respectively. Upon the completion of the Mergers, each NRCG stockholder and each US Ecology stockholder who receives shares of Holdco Common Stock will become a stockholder of the combined company with a percentage ownership of the combined company that is smaller than such stockholder's percentage ownership of NRCG or US Ecology, respectively. It is currently expected that the NRCG stockholders immediately prior to the Effective Time as a group will receive shares of Holdco Common Stock in connection with the Mergers constituting approximately 30% of the shares of Holdco Common Stock issued and outstanding immediately after the Mergers, and the US Ecology stockholders immediately prior to the Effective Time as a group will receive shares in the Mergers constituting approximately 70% of the shares of Holdco Common Stock immediately after the Mergers, each calculated on a fully diluted basis.

41


Table of Contents

Shares of Holdco Common Stock to be received by US Ecology stockholders in the ECOL Merger and NRCG stockholders in the NRCG Merger will have rights different from the shares of ECOL Common Stock and NRCG Common Stock, respectively.

        Upon completion of the Mergers, US Ecology stockholders and NRCG stockholders will no longer be US Ecology stockholders and/or NRCG stockholders, as applicable, but will instead be Holdco stockholders. The rights of former US Ecology stockholders and NRCG stockholders who become Holdco stockholders will be governed by the Holdco Amended Charter and the Holdco Amended Bylaws, each of which will be adopted, effective upon the Effective Time, in substantially the form attached as Annex E and Annex F, respectively, to this joint proxy statement/prospectus. The rights associated with shares of Holdco Common Stock are different from the rights associated with shares of ECOL Common Stock or NRCG Common Stock. See the section entitled "Comparison of Rights of NRCG Stockholders, US Ecology Stockholders and Holdco Stockholders" of this joint proxy statement/prospectus.

Holders of ECOL Common Stock and NRCG Common Stock will not be entitled to appraisal rights in the Mergers.

        Appraisal rights are statutory rights that, if applicable under law, enable stockholders to dissent from an extraordinary transaction, such as a merger, and to demand that the corporation pay the fair value for their shares as determined by a court in a judicial proceeding instead of receiving the consideration offered to stockholders in connection with the extraordinary transaction. Subject to certain exceptions, under the DGCL, stockholders do not have appraisal rights if the shares of stock they hold, as of the record date for determination of stockholders entitled to vote at the meeting of stockholders to act upon a merger, are among other things, listed on a national securities exchange. Because ECOL Common Stock is listed on Nasdaq, a national securities exchange, and is expected to continue to be so listed on the US Ecology Record Date, and because US Ecology stockholders will be entitled to receive shares of Holdco Common Stock in the ECOL Merger, which is expected to be listed on Nasdaq upon the Effective Time, US Ecology stockholders will not be entitled to appraisal rights in the ECOL Merger with respect to their shares of ECOL Common Stock. Because NRCG Common Stock is listed on the NYSE American, a national securities exchange, and is expected to continue to be so listed on the NRCG Record Date, and because NRCG stockholders will be entitled to receive shares of Holdco Common Stock in the NRCG Merger, which is expected to be listed on Nasdaq upon the Effective Time, NRCG stockholders will not be entitled to appraisal rights in the NRCG Merger with respect to their shares of NRCG Common Stock.

        Notwithstanding the foregoing, holders of NRCG Series A Preferred Stock will have appraisal rights, as further described in the section entitled "Appraisal Rights."

Risk Factors Relating to the Combined Company Following the Mergers

The combined company may be unable to integrate successfully the businesses of US Ecology and NRCG and realize the anticipated benefits of the Mergers.

        The success of the Mergers will depend, in large part, on the ability of the combined company to realize the anticipated benefits, including cost savings, from combining the businesses of US Ecology and NRCG. To realize these anticipated benefits, the businesses of US Ecology and NRCG must be integrated successfully. This integration will be complex and time consuming. The failure to successfully integrate and manage the challenges presented by the integration process may result in the combined company not fully achieving the anticipated benefits of the Mergers. Potential difficulties the combined

42


Table of Contents

company may encounter as part of the integration process, many of which may be beyond the control of management, include the following:

        In addition, US Ecology and NRCG have operated and, until the completion of the Mergers, will continue to operate independently. It is possible that the integration process could result in:

43


Table of Contents

The market price of Holdco Common Stock may be volatile, and holders of Holdco Common Stock could lose a significant portion of their investment due to drops in the market price of Holdco Common Stock following completion of the Mergers.

        The market price of Holdco Common Stock may be volatile, and following completion of the Mergers stockholders may not be able to resell their Holdco Common Stock at or above the price at which they acquired the Holdco Common Stock pursuant to the Merger Agreement or otherwise due to fluctuations in its market price, including changes in price caused by factors unrelated to the combined company's operating performance or prospects.

        Specific factors that may have a significant effect on the market price for Holdco Common Stock include, among others, the following:

US Ecology may not be able to obtain its preferred debt financing in connection with the Mergers on anticipated terms or at all.

        In connection with the closing of the Mergers, US Ecology intends to upsize its existing term loan under the Existing Credit Agreement from $500 million to $900 million pursuant to a proposed amendment to the Existing Credit Agreement. US Ecology expects to fund the repayment of NRCG's existing indebtedness and the payment of fees and expenses related to the Mergers using the proceeds of the upsized term loan as well as borrowings under US Ecology's existing revolving credit facility under the Existing Credit Agreement. However, there is a risk that US Ecology will not obtain the amendment to the Existing Credit Agreement on favorable terms or at all. As a result, US Ecology may need to pursue other options, which may result in less favorable financing terms that could increase costs and/or adversely impact the operations of US Ecology and the combined company following the Mergers.

The future results of the combined company will suffer if the combined company does not effectively manage its operations following the Mergers.

        The combined company's future success depends, in part, upon its ability to manage the combined businesses of US Ecology and NRCG, which will pose substantial challenges for management, including challenges related to the management and monitoring of new operations. There can be no assurances that the combined company will be successful or that it will realize the expected operating efficiencies, cost savings and other benefits currently anticipated from the Mergers.

Table of Contents

The combined company is expected to incur substantial expenses related to the Mergers and the integration of US Ecology and NRCG.

        The combined company is expected to incur substantial expenses in connection with the Mergers and the integration of US Ecology and NRCG. There are a large number of processes, policies, procedures, operations, technologies and systems that must be integrated, including purchasing, accounting, finance and payroll. While US Ecology and NRCG have assumed that a certain level of expenses would be incurred, there are many factors beyond their control that could affect the total amount or the timing of the integration expenses. Moreover, many of the expenses that will be incurred are, by their nature, difficult to estimate accurately. These expenses could, particularly in the near term, exceed the savings that the combined company expects to achieve from the elimination of duplicative expenses and the realization of economies of scale and cost savings. These integration expenses likely will result in the combined company taking significant charges against earnings following the completion of the Mergers, and the amount and timing of such charges are uncertain at present.

Holdco has no operating or financial history and the unaudited pro forma combined financial information included in this joint proxy statement/prospectus are preliminary. Therefore, the actual financial condition and results of operations of Holdco after the Mergers may differ materially from such preliminary pro forma information.

        Holdco has been recently incorporated in connection with the Mergers and has no operating history or revenues. This joint proxy statement/prospectus includes unaudited pro forma condensed combined financial statements for Holdco as of and for the year ended December 31, 2018, that combines the audited historical consolidated financial statements of US Ecology for the year ended December 31, 2018 with the audited historical financial statements of NRCG for the year ended December 31, 2018, and unaudited pro forma condensed combined financial statements for Holdco as of and for the six months ended June 30, 2019 that combines the unaudited historical consolidated financial statements of US Ecology for the six months ended June 30, 2019 with the unaudited historical financial statements of NRCG as of and for the six months ended June 30, 2019, in each case, adjusted to give effect to the Mergers, and should be read in conjunction with such financial statements and accompanying notes which are incorporated by reference in this joint proxy statement/prospectus. The unaudited pro forma condensed combined balance sheet of Holdco as of June 30, 2019 combines the audited historical balance sheets of US Ecology and NRCG as of June 30, 2019 and gives pro forma effect to the Mergers as if they had been consummated on June 30, 2019. The unaudited pro forma condensed combined statement of operations for the year ended December 31, 2018 and for the six months ended June 30, 2019 combines the US Ecology audited consolidated statements of operations and the NRCG audited statements of operations for the fiscal year ended December 31, 2018, and the US Ecology unaudited consolidated statements of operations and the NRCG unaudited statements of operations for the six months ended June 30, 2019, in each case, giving effect to the Mergers as if they had been consummated on January 1, 2018. The pro forma financial statements are presented for illustrative purposes only, are based on certain assumptions, address a hypothetical situation and reflect limited historical financial data. The pro forma financial statements do not include, among other things, estimated cost or growth synergies, adjustments related to restructuring or integration activities, future acquisitions or disposals not yet known or probable, including those that may be required by regulatory or governmental authorities in connection with the Mergers, or impacts of merger-related change in control provisions that are currently not factually supportable and/or probable of occurring. Therefore, the pro forma financial statements are presented for informational purposes only and are not necessarily indicative of what the combined company's actual financial condition or results of operations would have been had the Mergers been completed on the dates indicated. Accordingly, Holdco's business, assets, results of operations and financial condition may differ significantly from those indicated by the pro forma combined financial information included in

45

this joint proxy statement/prospectus. For more information, see the section entitled "Selected Unaudited Pro Forma Condensed Combined Financial Data" in this joint proxy statement/prospectus.

The financial forecasts of US Ecology and NRCG may not be realized, which may adversely affect the market price of Holdco Common Stock following the completion of the Mergers.

        Certain forecasts were prepared by, or at the direction of, the managements of US Ecology or NRCG, as applicable, in connection with the Mergers. None of these forecasts were prepared with a view towards public disclosure or compliance with the published guidelines of the SEC, GAAP, or the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of financial forecasts. These projections are inherently based on various estimates and assumptions that are subject to the judgment of those preparing them. These projections are also subject to significant economic, competitive, industry and other uncertainties and contingencies, all of which are difficult or impossible to predict and many of which are beyond the control of US Ecology and NRCG. There can be no assurance that US Ecology's or NRCG's financial condition or results of operations will be consistent with those set forth in such forecasts, which could have a material impact on the market price of Holdco Common Stock following the Mergers.

Subsequent to the consummation of the Mergers, Holdco's business would be adversely affected if it failed to comply with the Jones Act's restrictions on ownership of its capital stock by non-U.S. Citizens.

        A substantial portion of the operations of the standby services and environmental services provided by NRCG is conducted in the U.S. coastwise trade and is subject to the requirements of the Jones Act. As a result, following the Mergers, Holdco will be subject to the requirements of the Jones Act. The Jones Act restricts waterborne transportation of merchandise and passengers for hire by water or by land and water either directly or via a foreign port between points in the United States and certain of its island territories and possessions to U.S.-flag vessels meeting certain requirements, including that they are built in the United States, owned and controlled by U.S. Citizens (within the meaning of the Jones Act), and manned by predominantly U.S. citizen crews. NRCG is responsible for, and following the Mergers, Holdco will be responsible for, monitoring the non-U.S. Citizen ownership of their respective common stock and other equity interests to ensure compliance with the Jones Act. Following the Mergers, Holdco could lose the privilege of owning and operating vessels in the U.S. coastwise trade if non-U.S. Citizens were to own or control, in the aggregate, more than 25% of Holdco Common Stock or other equity interests in Holdco. Such a loss would have a material adverse effect on Holdco's business and results of operations. Violations of the Jones Act could result in Holdco losing eligibility to engage in the U.S. coastwise trade, the imposition of substantial penalties against Holdco, including fines and seizure and forfeiture of Holdco's vessels, and/or the temporary or permanent inability to document Holdco's vessels in the United States with coastwise endorsements, any of which could have a material adverse effect on Holdco's financial condition and results of operations. Although Holdco currently believes that it will meet the requirements to engage in the U.S. coastwise trade, and there are provisions in the Holdco Amended Charter that were designed to facilitate Holdco's compliance with these requirements, there can be no assurance that Holdco will be in compliance with the Jones Act in the future.

Subsequent to the consummation of the Mergers, repeal, amendment, suspension or non-enforcement of the Jones Act would result in additional competition for Holdco's standby services and environmental services division and could have a material adverse effect on its business.

        During the past several years, interest groups have lobbied the U.S. Congress, and legislation has been introduced, to repeal certain provisions of the Jones Act to facilitate foreign-flag vessel competition for trades and cargoes currently reserved for U.S.-flag vessels under the Jones Act. Holdco expects that continued efforts will be made to modify or repeal the Jones Act. In addition, the

46


Table of Contents

Secretary of the Department of Homeland Security may waive the requirement for using U.S.-flag vessels with coastwise endorsements in the U.S. coastwise trade in the interest of national defense. In addition, following the Mergers, Holdco's advantage as a U.S. Citizen operator of Jones Act vessels could be eroded by periodic efforts and attempts by foreign interests to circumvent certain aspects of the Jones Act. In addition, maritime transportation services are currently excluded from the General Agreement on Trade in Services ("GATS") and are the subject of reservations by the United States in the North American Free Trade Agreement ("NAFTA") and other international free trade agreements. If maritime cabotage services were included in the GATS, NAFTA or other international trade agreements, or if the restrictions contained in the Jones Act were otherwise repealed, altered or waived, the transportation of cargo and passengers between U.S. ports could be opened to foreign-flag, foreign-built vessels or foreign-owned vessels. To the extent such foreign competition is permitted from vessels built in lower-cost shipyards with promotional foreign tax incentives or favorable tax regimes and crewed by non-U.S. Citizens with lower wages and benefits than U.S. citizens, such competition could have a material adverse effect on Holdco's business, financial position, results of operations and cash flows.

Subsequent to the consummation of the Mergers, Holdco Common Stock will be subject to restrictions on ownership by non-U.S. Citizens, which could require divestiture by non-U.S. Citizen stockholders and could have a negative impact on the transferability of Holdco Common Stock, its liquidity and market value, and on a change of control of Holdco.

        Certain operations of NRCG are conducted in the U.S. coastwise trade and are governed by U.S. federal laws commonly known as the Jones Act. The Jones Act restricts the transportation of merchandise and passengers for hire by water or by land and water, either directly or via a foreign port, between points in the United States and certain of its island territories and possessions, to U.S.-flag vessels that meet certain requirements, including that they are built in the United States, owned and controlled by U.S. Citizens (within the meaning of the Jones Act), and manned by predominantly U.S. Citizen crews. Holdco could lose the privilege of owning and operating vessels in the U.S. coastwise trade and may become subject to penalties and risk seizure and forfeiture of its U.S.-flag vessels if non-U.S. Citizens were to own or control, in the aggregate, more than 25% of any class or series of the capital stock of Holdco. Such loss could have a material adverse effect on Holdco's results of operations.

        The Holdco Amended Charter authorizes with respect to any class or series of Holdco's capital stock certain rules, policies and procedures, including procedures with respect to transfer of shares, to assist in monitoring and maintaining compliance with the Jones Act's U.S. citizenship requirements, which may have an adverse effect on holders of shares of the Holdco Common Stock.

        In order to provide a reasonable margin for compliance with the Jones Act, the Holdco Amended Charter contains provisions that limit the aggregate percentage beneficial ownership by non-U.S. Citizens of any class or series of Holdco's capital stock (including the Holdco Common Stock) to 24% of the outstanding shares of each such class or series to ensure that ownership by non-U.S. Citizens will not exceed the maximum percentage permitted by the Jones Act (presently 25%).

        The aggregate percentage of non-U.S. Citizen ownership of outstanding Holdco Common Stock is expected to fluctuate based on daily trading, and may increase above the 24% maximum permitted percentage. At and during such times that the 24% maximum permitted percentage of shares of Holdco Common Stock held by non-U.S. Citizens is reached, Holdco will be unable to issue any further shares of Holdco Common Stock to non-U.S. Citizens (including any shares issuable upon exercise of the public warrants) or permit transfers of Holdco Common Stock to non-U.S. Citizens. Any issuance or transfer of shares in excess of such permitted percentage shall be ineffective against Holdco, and neither Holdco nor its transfer agent are required to register such purported issuance or transfer of shares or be required to recognize the purported transferee or owner as a stockholder of Holdco for

47


Table of Contents

any purpose whatsoever except to exercise Holdco's remedies. Any such excess shares in the hands of a non-U.S. Citizen shall not have any voting or dividend rights. In addition, Holdco, in its discretion, is entitled to redeem all or any portion of such shares most recently acquired (as determined by the Holdco Board in accordance with guidelines that are set forth in the Holdco Amended Charter), by non-U.S. Citizens, in excess of such maximum permitted percentage for such class or series at a redemption price based on a fair market value formula that is set forth in the Holdco Amended Charter, which is to be paid by the issuance of redemption warrants (the "Redemption Warrants") permitting the holders to receive shares of Holdco Common Stock in the future when the receipt thereof would not violate the Holdco Amended Charter at an exercise price of $0.01 per share. In the event that Holdco determines that Redemption Warrants would be treated by the United States Coast Guard as capital stock, or if Holdco is unable to issue the Redemption Warrants for any other reason, Holdco may redeem the excess shares with cash, promissory notes, a combination of both at the discretion of the Holdco Board or by any other means authorized or permitted under DGCL.

        As a result of these provisions, a purported stockholder who is a non-U.S. Citizen may not receive any return on its investment in any such excess shares it purportedly purchases or owns, as the case may be, and it may sustain a loss. Further, Holdco may have to incur additional indebtedness, or use available cash (if any), to fund all or a portion of such redemption, in which case Holdco's financial condition may be materially weakened. The existence and enforcement of these requirements could have an adverse impact on the liquidity or market value of Holdco's equity securities in the event that U.S. Citizens were unable to transfer shares in Holdco to non-U.S. Citizens. Furthermore, under certain circumstances, this ownership restriction could discourage, delay or prevent a change of control of Holdco.

        So that Holdco may monitor and maintain its compliance with the Jones Act following the consummation of the Mergers, provisions in the Holdco Amended Charter will permit Holdco to require that owners of any shares of Holdco capital stock provide confirmation of their citizenship. In the event that a person does not submit such documentation to us, those provisions provide Holdco with certain remedies, including the suspension of voting, dividend and distribution rights and treatment of such person as a non-U.S. Citizen unless and until Holdco receives the requested documentation confirming that such person is a U.S. Citizen. As a result of non-compliance with these provisions, an owner of the shares of Holdco Common Stock may lose significant rights associated with those shares.

        If, for any reason, Holdco is unable to effect such a redemption when such ownership of shares by non-U.S. Citizens is in excess of 25% of the Holdco Common Stock, or otherwise prevent non-U.S. Citizens in the aggregate from owning shares in excess of 25% of any class or series of Holdco capital stock, or it fails to exercise its redemption rights because it is unaware that such ownership exceeds such percentage, Holdco may be unable to comply with the Jones Act and may be required by the applicable governmental authorities to suspend its operations in the U.S. coastwise trade. Any such actions by governmental authorities would have a material adverse effect on Holdco's business, financial position, results of operations and cash flows.

The combined company will record goodwill and intangible assets that could become impaired and adversely affect its results of operations and financial condition.

        In accordance with GAAP, the Mergers will be accounted for as an acquisition of NRCG by US Ecology and will follow the acquisition method of accounting for business combinations. The assets and liabilities of NRCG will be consolidated with those of US Ecology and initially reported at their respective acquisition date fair values. The excess of the purchase price over the fair values of NRCG's assets and liabilities will be recorded as goodwill. The unaudited pro forma combined balance sheet as of June 30, 2019 reflects $459.3 million of goodwill and $389.0 million of intangible assets resulting from the Mergers, which are based on US Ecology management's preliminary fair value estimates and

48


Table of Contents

are subject to change, including due to fluctuations in the market value of ECOL Common Stock and other purchase price accounting considerations.

        The combined company will be required to assess goodwill and intangible assets for impairment at least annually. In the future the combined company may record charges against earnings resulting from impairment. Any determination requiring the write off of a significant portion of the combined company's goodwill or other intangible assets could adversely affect the combined company's results of operations and financial condition.

If the combined company is unable to manage its growth, its business and financial results could suffer.

        The combined company's future financial results will depend in part on its ability to profitably manage its core businesses, including any growth that the combined company may be able to achieve. Over the past several years, each of US Ecology and NRCG has engaged in the identification of, and competition for, growth and expansion opportunities. In order to achieve those initiatives, the combined company will need to, among other things, recruit, train, retain and effectively manage employees and expand its operations and financial control systems. If the combined company is unable to manage its businesses effectively and profitably, its business and financial results could suffer.

Other Risk Factors of NRCG and US Ecology

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

        This joint proxy statement/prospectus and the documents incorporated by reference into this joint proxy statement/prospectus contain certain forecasts and other forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 with respect to the financial condition, results of operations, business strategies, operating efficiencies or synergies, revenue enhancements, competitive positions, growth opportunities, plans and objectives of the management of each of US Ecology, NRCG and, following the Mergers, the combined company, the Mergers and the markets for Holdco Common Stock, ECOL Common Stock and NRCG Common Stock and various other matters. Statements in this joint proxy statement/prospectus and the documents incorporated by reference herein that are not historical facts are hereby identified as "forward-looking statements." These forward-looking statements relate to, among other things, future events or the future performance or operations of Holdco, US Ecology and NRCG. All statements other than historical facts may be forward-looking statements; words such as "anticipate," "believe," "could," "design," "estimate," "expect," "forecast," "goal," "guidance," "imply," "intend," "may", "objective," "opportunity," "outlook," "plan," "position," "potential," "predict," "project," "prospective," "pursue," "seek," "should," "strategy," "target," "would," "will" or other similar expressions that convey the uncertainty of future events or outcomes are used to identify forward-looking statements. Such forward-looking statements are not guarantees of future performance and are subject to risks, uncertainties and other factors, some of which are beyond the control of Holdco, US Ecology and NRCG. Factors that could cause Holdco's, US Ecology's or NRCG's actual results to differ materially from those implied in the forward-looking statements include: (1) the risk that the conditions to the closing of the transaction are not satisfied, including the risk that required approvals for the transaction from governmental authorities or the stockholders of Holdco, US Ecology or NRCG are not obtained; (2) the occurrence of any event, change or other circumstances that either could give rise to the right of one or both of US Ecology or NRCG to terminate the Merger Agreement; (3) litigation relating to the transaction; (4) uncertainties as to the timing of the consummation of the transaction and the ability of each party to consummate the transaction; (5) risks related to disruption of management time from ongoing business operations due to the proposed transaction; (6) unexpected costs, charges or expenses resulting from the proposed transaction; (7) the ability of Holdco, US Ecology and NRCG to retain and hire key personnel; (8) competitive responses to the proposed transaction and the impact of competitive services; (9) certain restrictions during the pendency of the Mergers that may impact Holdco's, US Ecology's or NRCG's ability to pursue certain business opportunities or strategic transactions; (10) the terms and availability of the indebtedness planned to be incurred in connection with the transaction to refinance NRCG's existing indebtedness; (11) potential adverse changes to business relationships resulting from the announcement or completion of the transaction; (12) the combined companies' ability to achieve the growth prospects and synergies expected from the transaction, as well as delays, challenges and expenses associated with integrating the combined companies' existing businesses; and (13) legislative, regulatory and economic developments, including changing business conditions in the industries in which Holdco, US Ecology and NRCG operate. Investors and potential investors are urged not to place undue reliance on forward-looking statements in this communication, which speak only as of this date. None of Holdco, US Ecology nor NRCG undertakes any obligation to revise or update publicly any forward-looking statement to reflect future events or circumstances. Nothing contained herein constitutes or will be deemed to constitute a forecast, projection or estimate of the future financial performance of Holdco or US Ecology, whether following the implementation of the proposed transaction or otherwise.

        Forward-looking statements are found at various places throughout this joint proxy statement/prospectus, including in the sections entitled "The Mergers" and "Risk Factors." Important factors that could cause actual results to differ materially from those indicated by such forward-looking statements include those set forth in US Ecology's and NRCG's filings with the SEC, including US Ecology's Annual Report on Form 10-K for the fiscal year ended December 31, 2018 filed on February 28, 2019,

as updated by the subsequent Quarterly Reports on Form 10-Q filed on May 6, 2019 and August 5, 2019, and NRCG's Annual Report on Form 10-K for the fiscal year ended December 31, 2018 filed on March 25, 2019, as updated by subsequent Quarterly Reports on Form 10-Q filed on May 7, 2019 and August 7, 2019. These important factors also include those set forth under "Risk Factors" in this joint proxy statement/prospectus.

        Due to these risks and uncertainties, there can be no assurance that the proposed Mergers or any other transaction described herein will in fact be completed in the manner described or at all. You should be aware that new factors may emerge from time to time and it is not possible for Holdco, US Ecology or NRCG to identify all such factors nor can Holdco, US Ecology or NRCG predict the impact of each such factor on the proposed transaction or the combined company. You should not place undue reliance on these forward-looking statements, which speak only as of the date of this document. Unless legally required, none of Holdco, US Ecology or NRCG undertakes any obligation and each expressly disclaim any such obligation, to update publicly any forward-looking statements, whether as a result of new information, future events, changed circumstances or otherwise. Furthermore, any information about the intentions of Holdco, US Ecology, NRCG or, following the Mergers, the combined company contained in any of their respective forward-looking statements reflect their intentions as of the date of such forward-looking statements, and are based upon, among other things, existing regulatory, technological, industry, competitive, economic and market conditions, and their assumptions as of such date. Holdco, US Ecology, NRCG or, following the Mergers, the combined company may change their intentions, strategies or plans at any time and without notice, based upon any changes in such factors or assumptions or otherwise.

Prospective Financial Information

        Neither US Ecology nor NRCG as a matter of course makes public projections as to future sales, earnings, or other results. However, management of each of US Ecology and NRCG, respectively, has prepared certain prospective financial information included in this joint proxy statement/prospectus. This prospective financial information was not prepared with a view toward public disclosure or with a view toward complying with the guidelines established by the American Institute of Certified Public Accountants with respect to prospective financial information or GAAP, but, in the view of the US Ecology's and NRCG's management, as applicable, was prepared on a reasonable basis, reflects the best currently available estimates and judgments, and presents, to the best of such management's knowledge and belief, the expected course of action and the expected future financial performance of US Ecology and NRCG, as applicable. However, this information is not fact and should not be relied upon as being necessarily indicative of future results of US Ecology or NRCG, and readers of this joint proxy statement/prospectus are cautioned not to place undue reliance on the prospective financial information.

        Neither US Ecology's independent auditor nor any other independent accountants, have compiled, examined, or performed any procedures with respect to the prospective financial information contained herein on behalf of US Ecology or any other person, nor have they expressed any opinion or any other form of assurance on such information or its achievability, and assume no responsibility for, and disclaim any association with, such prospective financial information.

        Neither NRCG's independent auditors, which are listed as experts below in the section entitled "Experts," nor any other independent accountants, have audited, reviewed, examined, compiled or applied agreed-upon procedures with respect to the accompanying prospective financial information contained herein on behalf of NRCG or any other person, nor have they expressed any opinion or any other form of assurance on such information or its achievability, and assume no responsibility for, and disclaim any association with such prospective financial information. The independent auditor reports of NRCG and its subsidiaries (each as listed as an expert below in the section "Experts") included or incorporated by reference in this joint proxy statement/prospectus relate to historical financial

statements. They do not extend to any prospective financial information and should not be seen to do so.

        Although presented with numerical specificity, the accompanying prospective financial information was prepared in the context of numerous variables, estimates, and assumptions that are inherently uncertain and may be beyond the control of US Ecology and NRCG, and which may prove not to have been, or to no longer be, appropriate. Although considered reasonable by US Ecology's and NRCG's management as of the date of their preparation, the prospective financial information is subject to many risks and uncertainties. Important factors that may affect actual results and cause actual results to differ materially from these projections include, but are not limited to, risks and uncertainties relating to each company's business (including its ability to achieve strategic goals, objectives, and targets over the applicable periods), industry performance, the regulatory environment, general business and economic conditions, market and financial conditions, and various risks set forth in US Ecology's and NRCG's reports filed with the SEC, and other factors described or referenced under the sections entitled "Risk Factors" and "Cautionary Statement Regarding Forward-Looking Statements" of this joint proxy statement/prospectus.

        The prospective financial information also reflects assumptions that are subject to change and are susceptible to multiple interpretations and periodic revisions based on actual results, revised prospects for each company's business, changes in general business or economic conditions, or any other transaction or event that has occurred or that may occur and that was not anticipated at the time the prospective financial information was prepared. Further, the prospective financial information does not take into account any circumstances, transactions, or events occurring after the date it was prepared. Accordingly, actual results will likely differ, and may differ materially, from those contained in the prospective financial information. There can be no assurance that these financial projections will be realized or that future financial results of US Ecology or NRCG (or, following consummation of the Mergers, the combined company) will not materially vary from these financial projections.

        Except as required by applicable securities laws, US Ecology and NRCG do not intend to, and disclaim any obligation to, make publicly available any update or other revision to the unaudited prospective financial and operating information to reflect circumstances existing since their preparation or to reflect the occurrence of unanticipated events, even in the event that any or all of the underlying assumptions are shown to be in error, including with respect to the accounting treatment of the Mergers under GAAP, or to reflect changes in general economic or industry conditions.

        No one has made or makes any representation to any stockholder regarding the validity, accuracy, or completeness of, the information included in the prospective financial information set forth below. Readers are cautioned not to place undue reliance on the accompanying prospective financial information.

THE US ECOLOGY SPECIAL MEETING

Date, Time and Place of the US Ecology Special Meeting

        The US Ecology Special Meeting will be held at 101 S. Capitol Blvd., Suite 1000, Boise, Idaho 83702, on October 23, 2019, at 10:00 a.m., local time.

Purpose of the US Ecology Special Meeting

        At the US Ecology Special Meeting, US Ecology stockholders will be asked to consider and vote upon the following proposals: (1) the US Ecology Merger Agreement Proposal, (2) the Holdco Stock Issuance Proposal, (3) the Holdco Charter Amendment Proposal and (4) the US Ecology Adjournment Proposal.

Recommendation of the US Ecology Board

        At a meeting of the US Ecology Board held on June 23, 2019, the US Ecology Board determined that the Merger Agreement and the transactions contemplated thereby, are in the best interests of US Ecology and its stockholders, and approved the Merger Agreement and the Mergers, the execution of the Merger Agreement and the consummation of the transactions contemplated thereby. Such determination, approval and recommendation were made unanimously by the US Ecology Board.

        The US Ecology Board recommends that US Ecology stockholders vote "FOR" the US Ecology Merger Agreement Proposal, the Holdco Stock Issuance Proposal, the Holdco Charter Amendment Proposal and, if necessary, the US Ecology Adjournment Proposal.

Record Date for the US Ecology Special Meeting; Stock Entitled to Vote

        Only holders of record of shares of ECOL Common Stock at the close of business on the US Ecology Record Date, will be entitled to notice of, and to vote at, the US Ecology Special Meeting and any postponements or adjournments thereof. You may cast one vote for each share of ECOL Common Stock that you owned as of the US Ecology Record Date, including (1) shares held directly in your name as the common stockholder of record and (2) shares held for you as the beneficial owner in street name through a broker, bank or other nominee.

        On the US Ecology Record Date, there were outstanding a total of 22,080,545 shares of ECOL Common Stock entitled to vote at the US Ecology Special Meeting.

Solicitation of Proxies; Revocability of Proxies

        The cost of proxy solicitation for the US Ecology Special Meeting and expenses for the filing, printing and mailing of this joint proxy statement/prospectus will be borne by US Ecology. In addition to the use of the mail, proxies may be solicited by officers and directors and regular employees of US Ecology, without additional remuneration, by personal interview, telephone, electronic communication or otherwise. US Ecology will also request brokerage firms, nominees, custodians and fiduciaries to forward proxy materials to the beneficial owners of shares held of record on the US Ecology Record Date and will provide customary reimbursement to such firms for the cost of forwarding these materials. US Ecology has retained Morrow Sodali to assist in its solicitation of proxies and has agreed to pay them a fee of up to $12,500, plus reasonable expenses, for these services.

        If you are a holder of record on the US Ecology Record Date, you have the power to revoke your proxy at any time before your proxy is voted at the US Ecology Special Meeting. You can revoke your proxy in one of four ways:

53


Table of Contents

        If you choose either of the first two methods, you must provide your notice of revocation or your new proxy to the Secretary of US Ecology prior to your shares being voted. If your shares are held in street name by your broker, bank or other nominee, you should contact them to change your vote.

Quorum

        Holders of ECOL Common Stock who hold shares representing at least a majority of the issued and outstanding shares of ECOL Common Stock entitled to vote at the US Ecology Special Meeting must be present in person or represented by proxy to constitute a quorum for the transaction of business at the US Ecology Special Meeting. If a quorum is not present, the US Ecology Special Meeting may be adjourned by the chairman of the US Ecology Special Meeting or the holders of a majority of shares of the ECOL Common Stock entitled to vote who are present, in person or by proxy, to another place, date, or time without notice other than announcement at the meeting, until a quorum shall be present or represented. Abstentions and broker non-votes are not included in the determination of the number of votes cast at the US Ecology Special Meeting, but abstentions are counted for purposes of determining whether a quorum is present.

Vote Required

        The US Ecology Merger Agreement Proposal requires the affirmative vote of holders of a majority of the issued and outstanding shares of ECOL Common Stock entitled to vote on the proposal. Failures to vote, abstentions and broker non-votes will have the effect of a vote against the proposal.

        The Holdco Stock Issuance Proposal requires the affirmative vote of the majority of all votes cast at the US Ecology Special Meeting and entitled to vote thereon. Failures to vote, abstentions and broker non-votes will have no effect on the outcome of the Holdco Stock Issuance Proposal, assuming a quorum is present.

        The Holdco Charter Amendment Proposal requires the affirmative vote of holders of a majority of the issued and outstanding shares of ECOL Common Stock entitled to vote on the proposal. Failures to vote, abstentions and broker non-votes will have the effect of a vote against the proposal.

        Approval of the US Ecology Adjournment Proposal requires the affirmative vote of the majority of all votes cast at the US Ecology Special meeting and entitled to vote thereon. Failures to vote, abstentions and broker non-votes will have no effect on the outcome of the adjournment proposal, assuming a quorum is present.

Abstentions and Broker Non-Votes

        Failures to vote, abstentions and broker non-votes will have the effect of a vote against the US Ecology Merger Agreement Proposal and the Holdco Charter Amendment Proposal. Failures to vote, abstentions and broker non-votes will have no effect on the outcome of the Holdco Stock Issuance Proposal or the US Ecology Adjournment Proposal. Shares of ECOL Common Stock represented by properly executed, timely received and unrevoked proxies will be voted in accordance with the instructions indicated thereon. If you are a US Ecology stockholder of record and you sign and return your proxy card without indicating how to vote on any particular proposal, the shares of ECOL

54


Table of Contents

Common Stock represented by your proxy will be counted as present for purposes of determining the presence of a quorum for the US Ecology Special Meeting and will be voted "FOR" that proposal. If you fail to cast a vote or deliver a proxy card, it will also make it more difficult to meet the quorum requirement with respect to organizing the meeting.

Voting Power of US Ecology's Directors and Executive Officers

        On the US Ecology Record Date, less than 1% of the outstanding ECOL Common Stock was held by US Ecology directors and executive officers. US Ecology currently expects that its directors and executive officers will vote their shares in favor of the US Ecology Merger Agreement Proposal, the Holdco Stock Issuance Proposal, the Holdco Charter Amendment Proposal and, if necessary, the US Ecology Adjournment Proposal, although no director or executive officer has entered into any agreement obligating him or her to do so.

Attending the US Ecology Special Meeting

        All holders of ECOL Common Stock, including stockholders of record and stockholders who hold shares through banks, brokers or other nominees, are invited to attend the US Ecology Special Meeting. Stockholders of record can vote in person at the US Ecology Special Meeting. If you plan to attend the special meeting, you must hold your shares in your own name or have a letter or an account statement issued by the record holder of your shares confirming your ownership, and you must bring a form of personal photo identification with you to be admitted. US Ecology reserves the right to refuse admittance to anyone without proper proof of share ownership and without proper photo identification. Even if you plan to attend the US Ecology Special Meeting, US Ecology recommends that you also submit your proxy or voting instructions by mail, or by telephone or on the Internet as described in your proxy card so that your vote will be counted if you later decide not to attend the meeting.

Voting of Proxies by Record Stockholders

        A proxy card is enclosed for use by US Ecology stockholders of record. US Ecology requests that its record stockholders sign the accompanying proxy and return it promptly in the enclosed postage-paid envelope. You may also submit a proxy to vote your shares by telephone or through the Internet. Information and applicable deadlines for submitting a proxy by telephone or through the Internet are set forth on the enclosed proxy card. Shares of US Ecology and ECOL Common Stock represented by properly executed, timely received and unrevoked proxies will be voted in accordance with the instructions indicated thereon. If you are a US Ecology stockholder of record and you sign and return your proxy card without indicating how to vote on any particular proposal, the shares of ECOL Common Stock represented by your proxy will be counted as present for purposes of determining the presence of a quorum for the US Ecology Special Meeting and will be voted "FOR" that proposal.

        As of the date hereof, US Ecology management has no knowledge of any business that will be presented for consideration at the US Ecology Special Meeting and which would be required to be set forth in this joint proxy statement/prospectus other than the matters set forth in US Ecology's accompanying Notice of Special Meeting of Stockholders. In accordance with US Ecology's bylaws and Delaware law, business transacted at the US Ecology Special Meeting will be limited to those matters set forth in such notice. Nonetheless, if any other matter is properly presented at the US Ecology Special Meeting for consideration, it is intended that the persons named in the enclosed proxy and acting thereunder will vote in accordance with their best judgment on such matter.

        Your vote is important. Whether or not you expect to attend the US Ecology Special Meeting in person, US Ecology urges you to submit a proxy to vote your shares as promptly as possible by (1) accessing the Internet website specified on your proxy card; (2) calling the toll-free number specified on your proxy card; or (3) signing and returning the enclosed proxy card in the postage-paid

envelope provided, so that your shares may be represented and voted at the US Ecology Special Meeting.

Shares Held in Street Name

        If you hold your shares of ECOL Common Stock in a stock brokerage account or if your shares are held by a broker, bank or other nominee (that is, in street name), you must provide the record holder of your shares with instructions on how to vote your shares if you wish them to be counted. Please follow the voting instructions provided by your broker, bank or other nominee. Please note that you may not vote shares held in street name by returning a proxy card directly to US Ecology or by voting in person at the US Ecology Special Meeting. Further, brokers who hold shares of ECOL Common Stock on behalf of their customers may not vote those shares without specific instructions from their customers.

        If you hold your ECOL Common Stock in street name and you do not instruct your broker on how to vote any of your shares, your broker may not vote those shares. For a discussion of the consequences of such broker non-votes, see the section entitled "The US Ecology Special Meeting—Abstentions and Broker Non-Votes" of this joint proxy statement/prospectus.

Revocability of Proxies and Changes to a US Ecology Stockholder's Vote

        If you are a holder of shares of ECOL Common Stock as of the US Ecology Record Date, you have the power to revoke your proxy at any time before your proxy is voted at the US Ecology Special Meeting. You can revoke your proxy in one of four ways:

        If you wish to change your vote at the US Ecology Special Meeting, you must vote by ballot at such meeting or if you wish to revoke any previously submitted proxy at the US Ecology Special Meeting, you must bring a written notice of revocation to the Secretary of the US Ecology Special Meeting prior to the voting at the US Ecology Special Meeting.

        If you are a US Ecology stockholder whose shares of ECOL Common Stock are held in "street name" by a broker, bank or other nominee, you may revoke your proxy or voting instructions and vote your shares in person at the US Ecology Special Meeting only in accordance with applicable rules and procedures as employed by your broker, bank or other nominee. If your shares are held in "street name" in an account at a broker, bank or other nominee, you must follow the directions you receive from your broker, bank or other nominee in order to change or revoke your proxy or voting instructions and should contact your broker, bank or other nominee to do so.

Adjournments

        Although it is not currently expected, the US Ecology Special Meeting may be adjourned for the purpose of soliciting additional proxies if US Ecology has not received sufficient proxies to constitute a quorum or sufficient votes for approval of the proposals to be presented at the US Ecology Special Meeting. If a quorum shall fail to attend the US Ecology Special Meeting, the chairman of the meeting

56


Table of Contents

or the holders of a majority of the shares of stock entitled to vote who are present, in person or by proxy, may adjourn the meeting to another place, date, or time without notice other than announcement at the meeting, until a quorum shall be present or represented.

        When a meeting is adjourned to another place, date or time, written notice need not be given of the adjourned meeting if the place, date and time thereof are announced at the meeting at which the adjournment is taken; provided however, that if the date of any adjourned meeting is more than 30 days after the date for which the meeting was originally noticed, or if a new record date is fixed for the adjourned meeting, written notice of the place, date, and time of the adjourned meeting shall be given in conformity herewith. At any adjourned meeting, any business may be transacted which might have been transacted at the original meeting.

Postponements

        At any time prior to convening the US Ecology Special Meeting, the US Ecology Board may postpone the US Ecology Special Meeting for any reason without the approval of the US Ecology stockholders. Although it is not currently expected, the US Ecology Board may postpone the US Ecology Special Meeting for the purpose of soliciting additional proxies if US Ecology has not received sufficient proxies to constitute a quorum or sufficient votes for approval of the proposals to be presented at the US Ecology Special Meeting. If the US Ecology Special Meeting is postponed, stockholders who have already sent in their proxies will be allowed to revoke them at any time prior to their use.

Stockholder List

        A list of US Ecology stockholders entitled to vote at the US Ecology Special Meeting will be available for inspection at US Ecology's principal executive offices, located at 101 S. Capitol Blvd., Suite 1000, Boise, Idaho 83702, at least ten days prior to the date of the US Ecology Special Meeting and continuing through the date thereof for any purpose germane to the US Ecology Special Meeting, between the hours of 9:00 a.m. and 4:30 p.m., local time. The list will also be available at the US Ecology Special Meeting for inspection by any US Ecology stockholder present at the US Ecology Special Meeting.

Tabulation of Votes

        A representative of US Ecology's mailing and tabulating agent, Broadridge Financial Solutions, Inc., will tabulate the votes and Wayne Ipsen, US Ecology's general counsel, will act as inspector of elections.

How You Can Reduce the Number of Copies of US Ecology's Proxy Materials You Receive

        Some brokers, banks and other nominee record holders may be participating in the practice of "householding" proxy statements and annual reports. This means that only one copy of this joint proxy statement/prospectus may have been sent to multiple stockholders in your household.

        If you are eligible for householding, but you and other stockholders of record with whom you share an address currently receive multiple copies of the proxy materials, or if you hold stock in more than one account, and, in either case, you wish to receive only a single copy of the proxy materials for your household, please contact your broker.

        If you participate in householding and wish to receive a separate copy of the proxy materials, or if you do not wish to continue to participate in householding and prefer to receive separate copies of the proxy materials in the future, please contact your broker or US Ecology. Direct your written request to Wayne R. Ipsen, Secretary, 101 S. Capitol Blvd., Suite 1000, Boise, Idaho, 83702; Telephone: (208) 331-8400.

        Beneficial owners can request information about householding from their banks, brokers, or other nominees.

US ECOLOGY PROPOSALS

US Ecology Proposal 1: US Ecology Merger Agreement Proposal

        US Ecology is asking its stockholders to approve the proposal to adopt the Merger Agreement.

        Under the terms of the Merger Agreement, ECOL Merger Sub will merge with and into US Ecology, with US Ecology as the surviving entity and continuing as a wholly-owned subsidiary of Holdco and, simultaneously therewith, Rooster Merger Sub will merge with and into NRCG, with NRCG as the surviving entity and continuing as a wholly-owned subsidiary of Holdco.

        In the ECOL Merger, each share of ECOL Common Stock issued and outstanding immediately prior to the Effective Time (other than cancelled shares) will be converted into the right to receive (1) one share of Holdco Common Stock and (2) any dividends or other distributions to which the holder thereof becomes entitled to upon the surrender of shares of ECOL Common Stock in accordance with the Merger Agreement. Outstanding equity awards of US Ecology will be assumed by Holdco and converted into equity awards at Holdco on a one-for-one basis as set forth in the Merger Agreement and described herein under the section entitled "The Merger Agreement—Treatment of US Ecology Stock Options, Restricted Stock Units, Performance Stock Units and Restricted Shares." Each share of ECOL Common Stock that is held by US Ecology as treasury stock or that is owned by Holdco, ECOL Merger Sub, US Ecology or any of their respective direct or indirect wholly-owned subsidiaries as of immediately prior to the Effective Time will automatically be cancelled and will cease to exist, without any conversion thereof, and no consideration will be delivered in exchange therefor.

        In the NRCG Merger, each share of NRCG Common Stock issued and outstanding immediately prior to the Effective Time (other than cancelled shares) will be converted into the right to receive, and become exchangeable for (1) the NRCG Exchange Ratio (0.196) of a share of Holdco Common Stock for each share of NRCG Common Stock, (2) any cash in lieu of fractional shares of Holdco Common Stock payable pursuant to the Merger Agreement and (3) any dividends or other distributions to which the holder thereof becomes entitled to upon the surrender of such shares of NRCG Common Stock in accordance with the Merger Agreement. Each share of NRCG Series A Preferred Stock issued and outstanding immediately prior to the Effective Time will be converted into the right to receive, and become exchangeable for (1) a whole number of shares of Holdco Common Stock equal to the product of (a) the number of shares of NRCG Common Stock that such share of NRCG Series A Preferred Stock could be converted into at the Effective Time (including Fundamental Change Additional Shares and Accumulated Dividends (each as defined in the NRCG Series A Certificate of Designations)) multiplied by (b) the NRCG Exchange Ratio, (2) any cash in lieu of fractional shares of Holdco Common Stock payable pursuant to the Merger Agreement and (3) any dividends or other distributions to which the holder thereof becomes entitled to upon the surrender of such shares of NRCG Series A Preferred Stock in accordance with the Merger Agreement. In the NRCG Merger, each share of NRCG Common Stock or NRCG Series A Preferred Stock that is owned by NRCG, Rooster Merger Sub or any of their respective direct or indirect wholly-owned subsidiaries immediately prior to the Effective Time will automatically be cancelled and will cease to exist, without any conversion thereof, and no consideration will be delivered in exchange therefor.

        Also at the Effective Time, US Ecology shall cause all shares of Holdco Common Stock that are issued and outstanding immediately prior to the Effective Time to be surrendered and cancelled and cease to exist, with no consideration delivered in exchange therefor.

        At the Effective Time, in respect of each NRCG Warrant issued pursuant to the NRCG Warrant Agreement, unless otherwise elected by the holder of any such NRCG Warrant, Holdco will issue a Replacement Warrant that complies with and satisfies the applicable terms and conditions under the NRCG Warrant Agreement to each holder of an NRCG Warrant providing that such Replacement Warrant will be exercisable for a number of shares of Holdco Common Stock equal to the product

Table of Contents

(rounded to the nearest whole number) of (1) the number of shares of NRCG Common Stock that would have been issuable upon the exercise of the NRCG Warrant immediately prior to the Effective Time and (2) the NRCG Exchange Ratio, at an exercise price equal to the quotient obtained by dividing (a) the pre-NRCG Merger exercise price ($11.50 per share) by (b) the NRCG Exchange Ratio. Following the closing of the Mergers, Holdco will comply with all terms and conditions set forth in each such Replacement Warrant.

        Outstanding shares of NRCG equity awards will be converted into equity awards of Holdco pursuant to the mechanics set forth in the Merger Agreement and described herein under the section entitled "The Merger Agreement—Treatment of NRCG Stock Options and Restricted Stock Units."

        For a summary and more detailed information regarding this proposal, see the information about the Mergers and the Merger Agreement throughout this joint proxy statement/prospectus, including the information set forth in sections entitled "The Mergers" and "The Merger Agreement" of this joint proxy statement/prospectus. A copy of the Merger Agreement is attached as Annex A to this joint proxy statement/prospectus.

US Ecology Proposal 2: Holdco Stock Issuance Proposal

As summarized in "US Ecology Proposal 1: The US Ecology Merger Agreement Proposal," in connection with the closing of the Mergers, Holdco will issue shares of Holdco Common Stock to NRCG and US Ecology stockholders pursuant to the Merger Agreement. Upon completion of the Mergers, and subject to the terms and conditions of the Merger Agreement, each share of NRCG Common Stock and ECOL Common Stock issued and outstanding immediately prior to the Effective Time will be converted into the right to receive, in accordance with the Merger Agreement, a number of shares of Holdco Common Stock as described in the section entitled "The Merger Agreement—Terms of the Mergers; Merger Consideration." In addition, in connection with the Mergers, Holdco will issue current holders of NRCG Warrants the Replacement Warrants, which may in the future be exercised to obtain shares of Holdco Common Stock as described in the section entitled "Description of Holdco Replacement Warrants."

Recommendation of the US Ecology Board

        The US Ecology Board recommends that US Ecology stockholders vote "FOR" the Holdco Stock Issuance Proposal.

US Ecology Proposal 3: Holdco Charter Amendment Proposal

        US Ecology stockholders are being asked to consider and vote upon a proposal to add certain provisions to the charter of Holdco that will be in effect after completion of the Mergers and that are not in the current charter of US Ecology. Upon the adoption of the Holdco Amended Charter, the new Holdco charter will be substantially identical to the existing US Ecology charter, with the addition of certain provisions to adopt ownership qualifications, restrictions, requirements and procedures to facilitate Holdco's compliance with the U.S. citizenship requirements of the Jones Act. A copy of the Holdco Amended Charter marked against the existing US Ecology charter is attached hereto as Annex E.

        Upon the consummation of the Mergers, Holdco will be subject to the requirements of the Jones Act. The Jones Act restricts transportation of merchandise by water, or by land and water, either directly or via a foreign port between points in the United States and certain of its island territories and possessions to U.S. flag vessels that meet certain requirements, including that they are built in the United States, owned and controlled by U.S. Citizens (within the meaning of the Jones Act), and manned by predominantly U.S. Citizen crews.

        Under the Jones Act, a corporation (such as Holdco) is deemed a U.S. Citizen if (1) it is organized under the laws of the United States or a state, (2) the chief executive officer, by whatever title, and the chairman of the board of directors of the corporation are U.S. Citizens, (3) not more than a minority of the number of the directors necessary to constitute a quorum of the board of directors are non-U.S. Citizens, and (4) at least 75% of the ownership and voting power of each class or series of the corporation's stock is owned and controlled by U.S. Citizens. The Jones Act specifies that ownership of at least 75% of the equity interest by U.S. Citizens means ownership free from any trust or fiduciary obligations in favor of, or any agreement, arrangement or understanding or other means by which more than 25% of the voting power or control of the corporation may be exercised directly or indirectly by or on behalf of, non-U.S. Citizens. These citizenship requirements apply at each tier in the Holdco ownership chain, which means that they must be satisfied by each person that contributes to Holdco's eligibility as a U.S. Citizen, and each person that contributes to the eligibility of such other person as a U.S. Citizen at each tier of ownership.

        In order to assist Holdco in facilitating compliance with the Jones Act following the closing of the Mergers, the proposed Holdco Amended Charter includes in Article Eighth provisions (1) limiting the ownership of any class or series of Holdco capital stock by non-U.S. Citizens to 24% (so as to allow a margin of safety under the statutory maximum of 25%), (2) prohibiting the transfer of shares of Holdco capital stock if doing so would cause Holdco to exceed the 24% non-U.S. Citizen ownership threshold (the "Excess Shares" as defined in the proposed Holdco Amended Charter), (3) authorizing the redemption of Excess Shares, (4) suspending the right to vote and to receive dividends and distributions for such Excess Shares, (5) establishing procedures for the redemption of Excess Shares including providing notice and setting the redemption price, (6) authorizing Holdco to make citizenship determinations with respect to the holders of its capital stock, (7) requiring holders (including

61


Table of Contents

beneficial holders) of Holdco capital stock to submit information to establish the citizenship of such holder, and (8) generally authorizing the Holdco Board to take appropriate action to monitor and maintain compliance with the ownership requirements of the Jones Act. In addition to the foregoing, the adoption of the Holdco Amended Charter would change the name of Holdco for "US Ecology Parent, Inc." to "US Ecology, Inc."

        US Ecology is requesting that US Ecology stockholders approve the Holdco Charter Amendment Proposal. Approval of this proposal requires the affirmative vote of the holders of a majority of the issued and outstanding shares of ECOL Common Stock entitled to vote at the US Ecology Special Meeting.

        Pursuant to the Merger Agreement, approval of this proposal by US Ecology stockholders is a condition to the consummation of the Mergers. If this proposal is not approved, the Mergers will not be consummated.

        A failure to vote, a broker non-vote or an abstention will have the same effect as a vote "AGAINST" the Holdco Charter Amendment Proposal.

Recommendation of the US Ecology Board

        The US Ecology Board recommends that US Ecology stockholders vote "FOR" the Holdco Charter Amendment Proposal.

US Ecology Proposal 4: The US Ecology Adjournment Proposal

        US Ecology is asking its stockholders to approve the proposal to adjourn the US Ecology Special Meeting to another time and place if necessary to permit solicitation of additional proxies if there are not sufficient votes to approve US Ecology Merger Agreement Proposal, the Holdco Stock Issuance Proposal or the Holdco Charter Amendment Proposal or to ensure that any supplement or amendment to the accompanying joint proxy statement/prospectus is timely provided to US Ecology stockholders.

        US Ecology is requesting that US Ecology stockholders approve the US Ecology Adjournment Proposal. Approval of this proposal requires the affirmative vote of the holders of a majority of all votes cast at the US Ecology Special Meeting and entitled to vote thereon.

        Failures to vote, abstentions and broker non-votes will have no effect on the outcome of the US Ecology Adjournment Proposal, assuming a quorum is present.

THE NRCG SPECIAL MEETING

Date, Time and Place of the NRCG Special Meeting

        The NRCG Special Meeting will be held at 717 Texas, Suite 3300, Houston, Texas 77002, on October 22, 2019, at 9:00 a.m., local time.

Purpose of the NRCG Special Meeting

        At the NRCG Special Meeting, NRCG common stockholders will be asked to consider and vote upon the following proposals: (1) the NRCG Merger Agreement Proposal and (2) the NRCG Adjournment Proposal.

Recommendation of the NRCG Board

        At a meeting of the NRCG Board held on June 23, 2019, the NRCG Board determined that the Merger Agreement and the transactions contemplated thereby, are in the best interests of NRCG and its common stockholders, and approved the Merger Agreement and the Mergers, the execution of the Merger Agreement and the consummation of the transactions contemplated thereby. Such determination, approval and recommendation were made by eight of the nine directors on the NRCG Board.

        The NRCG Board recommends that NRCG common stockholders vote "FOR" the NRCG Merger Agreement Proposal and, if necessary, the NRCG Adjournment Proposal.

Record Date for the NRCG Special Meeting; Stock Entitled to Vote

        Only holders of record of shares of NRCG Common Stock at the close of business on the NRCG Record Date will be entitled to vote at the NRCG Special Meeting and any postponements or adjournments thereof. You may cast one vote for each share of NRCG Common Stock that you owned as of the NRCG Record Date, including (1) shares held directly in your name as the common stockholder of record and (2) shares held for you as the beneficial owner in street name through a broker, bank or other nominee.

        On the NRCG Record Date, there were outstanding a total of 38,050,385 shares of NRCG Common Stock entitled to vote at the NRCG Special Meeting.

Solicitation of Proxies; Revocability of Proxies

        The cost of proxy solicitation for the NRCG Special Meeting and expenses for the filing, printing and mailing of this joint proxy statement/prospectus will be borne by NRCG. In addition to the use of the mail, proxies may be solicited by officers and directors and regular employees of NRCG, without additional remuneration, by personal interview, telephone, electronic communication or otherwise. NRCG will also request brokerage firms, nominees, custodians and fiduciaries to forward proxy materials to the beneficial owners of shares held of record on the NRCG Record Date and will provide customary reimbursement to such firms for the cost of forwarding these materials.

        If you are a holder of record of NRCG Common Stock on the NRCG Record Date, you have the power to revoke your proxy at any time before your proxy is voted at the NRCG Special Meeting. You can revoke your proxy in one of four ways:

63


Table of Contents

        If you choose either of the first two methods, you must provide your notice of revocation or your new proxy to the General Counsel of NRCG prior to your shares being voted. If your shares are held in street name by your broker, bank or other nominee, you should contact them to change your vote.

Quorum

        Stockholders who hold shares representing at least a majority of the issued and outstanding shares of NRCG Common Stock entitled to vote at the NRCG Special Meeting must be present in person or represented by proxy to constitute a quorum for the transaction of business at the NRCG Special Meeting. If a quorum is not present, the NRCG Special Meeting may be adjourned by the chairman of the NRCG Special Meeting to another place, date, or time without notice other than announcement at the meeting, until a quorum shall be present or represented. Abstentions and broker non-votes will be counted for purposes of determining whether a quorum is present at the NRCG Special Meeting. As a result of the Support Agreement, and subject to the terms thereof, holders of a majority of the issued and outstanding shares of NRCG Common Stock entitled to vote at the NRCG Special Meeting have agreed to vote their shares in favor of the NRCG Merger Agreement Proposal and the presence of a quorum is effectively assured.

Vote Required

        Approval of the NRCG Merger Agreement Proposal requires the affirmative vote of holders of a majority of the issued and outstanding shares of NRCG Common Stock entitled to vote on the proposal. Failures to vote, abstentions and broker non-votes will have the effect of a vote against the NRCG Merger Agreement Proposal.

        Approval of the NRCG Adjournment Proposal requires the affirmative vote of the majority of all votes cast at the NRCG Special Meeting and entitled to vote thereon. Failures to vote, abstentions and broker non-votes will have no effect on the outcome of the NRCG Adjournment Proposal, assuming a quorum is present.

Abstentions and Broker Non-Votes

        Failures to vote, abstentions and broker non-votes will have the effect of a vote against the NRCG Merger Agreement Proposal. Failures to vote, abstentions and broker non-votes will have no effect on the outcome of the NRCG Adjournment Proposal. Shares of NRCG Common Stock represented by properly executed, timely received and unrevoked proxies will be voted in accordance with the instructions indicated thereon. If you are a NRCG common stockholder of record and you sign and return your proxy card without indicating how to vote on any particular proposal, the shares of NRCG Common Stock represented by your proxy will be counted as present for purposes of determining the presence of a quorum for the NRCG Special Meeting and will be voted "FOR" that proposal. If you fail to cast a vote or deliver a proxy card, it will also make it more difficult to meet the quorum requirement with respect to organizing the meeting.

Voting Power of NRCG Directors and Executive Officers

        On the NRCG Record Date, approximately 70% of the outstanding NRCG Common Stock was directly held by NRCG directors and executive officers and the JFL Entities.

Attending the NRCG Special Meeting

        All holders of NRCG Common Stock, including stockholders of record and stockholders who hold shares through banks, brokers or other nominees, are invited to attend the NRCG Special Meeting. Common stockholders of record can vote in person at the NRCG Special Meeting. If you plan to attend the NRCG Special Meeting, you must hold your shares in your own name or have a letter or an account statement issued by the record holder of your shares confirming your ownership, and you must bring a form of personal photo identification with you to be admitted. NRCG reserves the right to refuse admittance to anyone without proper proof of share ownership and without proper photo identification. Even if you plan to attend the NRCG Special Meeting, NRCG recommends that you also submit your proxy or voting instructions by mail, or by telephone or on the Internet as described in your proxy card so that your vote will be counted if you later decide not to attend the meeting.

Voting of Proxies by Record Stockholders

        A proxy card is enclosed for use by NRCG common stockholders of record. NRCG requests that its record common stockholders sign the accompanying proxy and return it promptly in the enclosed postage-paid envelope. You may also submit a proxy to vote your shares by telephone or through the Internet. Information and applicable deadlines for submitting a proxy by telephone or through the Internet are set forth on the enclosed proxy card. Shares of NRCG Common Stock represented by properly executed, timely received and unrevoked proxies will be voted in accordance with the instructions indicated thereon. If you are a NRCG common stockholder of record and you sign and return your proxy card without indicating how to vote on any particular proposal, the shares of NRCG Common Stock represented by your proxy will be counted as present for purposes of determining the presence of a quorum for the NRCG Special Meeting and will be voted "FOR" that proposal.

        As of the date hereof, NRCG management has no knowledge of any business that will be presented for consideration at the NRCG Special Meeting and which would be required to be set forth in this joint proxy statement/prospectus other than the matters set forth in NRCG's accompanying Notice of Special Meeting of Common Stockholders. In accordance with NRCG's bylaws and Delaware law, business transacted at the NRCG Special Meeting will be limited to those matters set forth in such notice. Nonetheless, if any other matter is properly presented at the NRCG Special Meeting for consideration, it is intended that the persons named in the enclosed proxy and acting thereunder will vote in accordance with their best judgment on such matter.

        Your vote is important. Whether or not you expect to attend the NRCG Special Meeting in person, NRCG urges you to submit a proxy to vote your shares as promptly as possible by (1) accessing the Internet website specified on your proxy card; (2) calling the toll-free number specified on your proxy card; or (3) signing and returning the enclosed proxy card in the postage-paid envelope provided, so that your shares may be represented and voted at the NRCG Special Meeting.

Shares Held in Street Name

        If you hold your shares of NRCG Common Stock in a stock brokerage account or if your shares are held by a broker, bank or other nominee (that is, in street name), you must provide the record holder of your shares with instructions on how to vote your shares if you wish them to be counted. Please follow the voting instructions provided by your broker, bank or other nominee. Please note that you may not vote shares held in street name by returning a proxy card directly to NRCG or by voting in person at the NRCG Special Meeting. Further, brokers who hold shares of NRCG Common Stock on behalf of their customers may not vote those shares without specific instructions from their customers.

        If you hold your NRCG Common Stock in street name and you do not instruct your broker on how to vote any of your shares, your broker may not vote those shares. For a discussion of the

65


Table of Contents

consequences of such broker non-votes, see the section entitled "The NRCG Special Meeting—Abstentions and Broker Non-Votes" of this joint proxy statement/prospectus.

Revocability of Proxies and Changes to a NRCG Common Stockholder's Vote

        If you are a holder of shares of NRCG Common Stock as of the NRCG Record Date, you have the power to revoke your proxy at any time before your proxy is voted at the NRCG Special Meeting. You can revoke your proxy in one of four ways:

        If you wish to change your vote at the NRCG Special Meeting, you must vote by ballot at such meeting or if you wish to revoke any previously submitted proxy at the NRCG Special Meeting, you must bring a written notice of revocation to the general counsel of NRCG at the NRCG Special Meeting prior to the voting at the NRCG Special Meeting.

        If you are a NRCG common stockholder whose shares of NRCG Common Stock are held in "street name" by a broker, bank or other nominee, you may revoke your proxy or voting instructions and vote your shares in person at the NRCG Special Meeting only in accordance with applicable rules and procedures as employed by your broker, bank or other nominee. If your shares are held in "street name" in an account at a broker, bank or other nominee, you must follow the directions you receive from your broker, bank or other nominee in order to change or revoke your proxy or voting instructions and should contact your broker, bank or other nominee to do so.

Adjournments

        Although it is not currently expected, the NRCG Special Meeting may be adjourned for the purpose of soliciting additional proxies if NRCG has not received sufficient proxies to constitute a quorum or sufficient votes for approval of the proposals to be presented at the NRCG Special Meeting. For more information see the section entitled "The NRCG Special Meeting—Quorum." If a quorum shall fail to attend the NRCG Special Meeting, the chairman of the meeting may adjourn the meeting to reconvene at the same or some other place.

        When a meeting is adjourned to another place, date or time, notice need not be given of the adjourned meeting if the place, date and time thereof are announced at the meeting at which the adjournment is taken; provided however, that if the date of any adjourned meeting is more than 30 days after the date for which the meeting was originally noticed, or if a new record date is fixed for the adjourned meeting, written notice of the place, date, and time of the adjourned meeting shall be given in conformity herewith. At any adjourned meeting, any business may be transacted which might have been transacted at the original meeting.

Postponements

        At any time prior to convening the NRCG Special Meeting, the NRCG Board may postpone the NRCG Special Meeting for any reason without the approval of the NRCG common stockholders. Although it is not currently expected, the NRCG Board may postpone the NRCG Special Meeting for

66


Table of Contents

the purpose of soliciting additional proxies if NRCG has not received sufficient proxies to constitute a quorum or sufficient votes for approval of the proposals to be presented at the NRCG Special Meeting. If the NRCG Special Meeting is postponed, NRCG common stockholders who have already sent in their proxies will be allowed to revoke them at any time prior to their use.

Stockholder List

        A list of NRCG common stockholders entitled to vote at the NRCG Special Meeting will be available for inspection at NRCG's principal executive offices, located at 952 Echo Lane, Suite 460, Houston, TX 77024, at least ten days prior to the date of the NRCG Special Meeting and continuing through the date thereof for any purpose germane to the NRCG Special Meeting, between the hours of 9:00 a.m. and 4:30 p.m., local time.

How You Can Reduce the Number of Copies of US Ecology's Proxy Materials You Receive

        Some brokers, banks and other nominee record holders may be participating in the practice of "householding" proxy statements and annual reports. This means that only one copy of this joint proxy statement/prospectus may have been sent to multiple NRCG common stockholders in your household.

        If you are eligible for householding, but you and other NRCG common stockholders of record with whom you share an address currently receive multiple copies of the proxy materials, or if you hold stock in more than one account, and, in either case, you wish to receive only a single copy of the proxy materials for your household, please contact your broker.

        If you participate in householding and wish to receive a separate copy of the proxy materials, or if you do not wish to continue to participate in householding and prefer to receive separate copies of the proxy materials in the future, please contact your broker or NRC Group Holdings Corp., 952 Echo Lane, Suite 460, Houston, Texas 77024, Attention: General Counsel.

        Beneficial owners can request information about householding from their banks, brokers, or other nominees.

NRCG PROPOSALS

NRCG Proposal 1: The NRCG Merger Agreement Proposal

        NRCG is asking its common stockholders to approve the proposal to adopt the Merger Agreement.

        Under the terms of the Merger Agreement, ECOL Merger Sub will merge with and into US Ecology, with US Ecology as the surviving entity and continuing as a wholly-owned subsidiary of Holdco and, simultaneously therewith, Rooster Merger Sub will merge with and into NRCG, with NRCG as the surviving entity and continuing as a wholly-owned subsidiary of Holdco.

        In the ECOL Merger, each share of ECOL Common Stock issued and outstanding immediately prior to the Effective Time (other than cancelled shares) will be converted into the right to receive (1) one share of Holdco Common Stock and (2) any dividends or other distributions to which the holder thereof becomes entitled to upon the surrender of shares of ECOL Common Stock in accordance with the Merger Agreement. Outstanding equity awards of US Ecology will be assumed by Holdco and converted into equity awards at Holdco on a one-for-one basis as set forth in the Merger Agreement and described herein under the section entitled "The Merger Agreement—Treatment of US Ecology Stock Options, Restricted Stock Units, Performance Stock Units and Restricted Shares." Each share of ECOL Common Stock that is held by US Ecology as treasury stock or that is owned by Holdco, ECOL Merger Sub, US Ecology or any of their respective direct or indirect wholly-owned subsidiaries as of immediately prior to the Effective Time will automatically be cancelled and will cease to exist, without any conversion thereof, and no consideration will be delivered in exchange therefor.

        In the NRCG Merger, each share of NRCG Common Stock issued and outstanding immediately prior to the Effective Time (other than cancelled shares) will be converted into the right to receive, and become exchangeable for (1) the NRCG Exchange Ratio (0.196) of a share of Holdco Common Stock for each share of NRCG Common Stock, (2) any cash in lieu of fractional shares of Holdco Common Stock payable pursuant to the Merger Agreement and (3) any dividends or other distributions to which the holder thereof becomes entitled to upon the surrender of such shares of NRCG Common Stock in accordance with the Merger Agreement. Each share of NRCG Series A Preferred Stock issued and outstanding immediately prior to the Effective Time will be converted into the right to receive, and become exchangeable for (1) a whole number of shares of Holdco Common Stock equal to the product of (a) the number of shares of NRCG Common Stock that such share of NRCG Series A Preferred Stock could be converted into at the Effective Time (including Fundamental Change Additional Shares and Accumulated Dividends (each as defined in the NRCG Series A Certificate of Designations)) multiplied by (b) the NRCG Exchange Ratio, (2) any cash in lieu of fractional shares of Holdco Common Stock payable pursuant to the Merger Agreement and (3) any dividends or other distributions to which the holder thereof becomes entitled to upon the surrender of such shares of NRCG Series A Preferred Stock in accordance with the Merger Agreement. In the NRCG Merger, each share of NRCG Common Stock or NRCG Series A Preferred Stock that is owned by NRCG, Rooster Merger Sub or any of their respective direct or indirect wholly-owned subsidiaries immediately prior to the Effective Time will automatically be cancelled and will cease to exist, without any conversion thereof, and no consideration will be delivered in exchange therefor.

        Also at the Effective Time, US Ecology shall cause all shares of Holdco Common Stock that are issued and outstanding immediately prior to the Effective Time to be surrendered and cancelled and cease to exist, with no consideration delivered in exchange therefor.

        At the Effective Time, in respect of each NRCG Warrant issued pursuant to the NRCG Warrant Agreement, unless otherwise elected by the holder of any such NRCG Warrant, Holdco will issue a Replacement Warrant that complies with and satisfies the applicable terms and conditions under the NRCG Warrant Agreement to each holder of an NRCG Warrant providing that such Replacement

69


Table of Contents

Warrant will be exercisable for a number of shares of Holdco Common Stock equal to the product (rounded to the nearest whole number) of (1) the number of shares of NRCG Common Stock that would have been issuable upon the exercise of the NRCG Warrant immediately prior to the Effective Time and (2) the NRCG Exchange Ratio, at an exercise price equal to the quotient obtained by dividing (a) the pre-NRCG Merger exercise price ($11.50 per share) by (b) the NRCG Exchange Ratio. Following the closing of the Mergers, Holdco will comply with all terms and conditions set forth in each such Replacement Warrant.

        Outstanding shares of NRCG equity awards will be converted into equity awards of Holdco pursuant to the mechanics set forth in the Merger Agreement and described herein under the section entitled "The Merger Agreement—Treatment of NRCG Stock Options and Restricted Stock Units."

        For a summary and more detailed information regarding this proposal, see the information about the Mergers and the Merger Agreement throughout this joint proxy statement/prospectus, including the information set forth in sections entitled "The Mergers" and "The Merger Agreement" of this joint proxy statement/prospectus. A copy of the Merger Agreement is attached as Annex A to this joint proxy statement/prospectus.

        Pursuant to the Merger Agreement, approval of this proposal by NRCG common stockholders is a condition to the consummation of the Mergers. If this proposal is not approved, the Mergers will not be consummated.

        NRCG is requesting that NRCG common stockholders approve the proposal to adopt the Merger Agreement. Approval of this proposal requires the affirmative vote of the holders of a majority of the issued and outstanding shares of NRCG Common Stock entitled to vote as of the record date for the NRCG Special Meeting.

        A failure to vote, a broker non-vote or an abstention will have the same effect as a vote "AGAINST" the NRCG Merger Agreement Proposal.

Recommendation of the NRCG Board

        The NRCG Board recommends that NRCG common stockholders vote "FOR" the NRCG Merger Agreement Proposal.

NRCG Proposal 2: The NRCG Adjournment Proposal

        NRCG is asking its common stockholders to approve the proposal to adjourn the NRCG Special Meeting to another time and place if necessary to permit solicitation of additional proxies if there are not sufficient votes to approve the NRCG Merger Agreement Proposal or to ensure that any supplement or amendment to this joint proxy statement/prospectus is timely provided to NRCG common stockholders.

        NRCG is requesting that NRCG common stockholders approve the NRCG Adjournment Proposal. Approval of this proposal requires the affirmative vote of the majority of all votes cast at the NRCG Special Meeting and entitled to vote thereon.

THE MERGERS

        The following is a description of the material aspects of the Mergers, including the Merger Agreement. While we believe that the following description covers the material terms of the Mergers, the description may not contain all of the information that is important to you. We encourage you to read this joint proxy statement/prospectus carefully and in its entirety, including the Merger Agreement which is attached as Annex A to this joint proxy statement/prospectus, for a more complete understanding of the Mergers.

Effects of the Mergers

        Upon the terms and subject to the conditions of the Merger Agreement and in accordance with the DGCL, at the Effective Time, ECOL Merger Sub, a wholly-owned subsidiary of Holdco and a party to the Merger Agreement, will merge with and into US Ecology. US Ecology will survive the ECOL Merger as a wholly-owned subsidiary of Holdco. Upon the terms and subject to the conditions of the Merger Agreement and in accordance with the DGCL, at the Effective Time, Rooster Merger Sub, a wholly-owned subsidiary of Holdco and a party to the Merger Agreement, will merge with and into NRCG. NRCG will survive the NRCG Merger as a wholly-owned subsidiary of Holdco. As a result, among other things, Holdco will become the ultimate parent of US Ecology, NRCG and their respective subsidiaries as a result of the Mergers. The Mergers will become effective at the time at which the certificates of merger have been duly filed with the Secretary of State of the State of Delaware or at any later date or time mutually agreed to in writing by US Ecology and NRCG and specified in the certificates of merger in accordance with the DGCL.

        At the Effective Time, each issued and outstanding share of ECOL Common Stock (other than shares owned by Holdco, ECOL Merger Sub, US Ecology or any of their respective subsidiaries, which will automatically be cancelled and will cease to exist, without any conversion thereof, and no consideration will be delivered in exchange therefor) will be converted into the right to receive (1) 1.00 share of Holdco Common Stock and (2) any dividends or other distributions to which the holder thereof becomes entitled to upon the surrender of such shares of ECOL Common Stock.

        Also at the Effective Time, each issued and outstanding share of NRCG Common Stock (other than shares owned by US Ecology, Holdco, Rooster Merger Sub or NRCG, which will automatically be cancelled and will cease to exist, without any conversion thereof, and no consideration will be delivered in exchange therefor) will be converted into the right to receive, and become exchangeable for, (1) 0.196 of a share of Holdco Common Stock for each share of NRCG Common Stock, (2) any cash paid in lieu of fractional shares of Holdco Common Stock payable pursuant to the Merger Agreement and (3) any dividends or other distributions to which the holder thereof becomes entitled to upon the surrender of such shares of NRCG Common Stock.

        In addition, at the Effective Time, each share of NRCG Series A Preferred Stock (other than shares owned by US Ecology, Holdco, Rooster Merger Sub, NRCG or any of their respective subsidiaries, which will cease to remain outstanding and will be canceled and cease to exist) will be converted into the right to receive, and become exchangeable for, (1) a whole number of shares of Holdco Common Stock equal to the product of (a) the number of shares of NRCG Common Stock that such share of NRCG Series A Preferred Stock could be converted into at the Effective Time (including, for the avoidance of doubt, the applicable Fundamental Change Additional Shares and Accumulated Dividends, each as defined in the NRCG Series A Certificate of Designations) multiplied by (b) the NRCG Exchange Ratio, (2) any cash paid in lieu of fractional shares of Holdco Common Stock payable pursuant to the Merger Agreement and (3) any dividends or other distributions to which the holder thereof becomes entitled to upon the surrender of such shares of NRCG Series A Preferred Stock.

        The exchange ratios are fixed and will not be adjusted to reflect stock price changes prior to the closing of the Mergers.

        US Ecology and NRCG are working to complete the Mergers as soon as practicable and expect the closing of the Mergers to occur in the fourth quarter of 2019. However, the Mergers are subject to the satisfaction or waiver of certain conditions, and it is possible that factors outside the control of Holdco, US Ecology and NRCG could result in the Mergers being completed at a later time or not at all.

Background of the Mergers

        The NRCG Board and the US Ecology Board, together with their respective management teams, each regularly review their respective results of operations, competitive positions, business opportunities and potential transactions, including strategic alternatives and transactions that would strengthen their respective competitive positions; further strategic objectives and business opportunities; and enhance stockholder value.

        On October 17, 2018, all of the outstanding equity interests of NRC Group were acquired from JFL Partners by HCAC (the "SPAC Transaction"). HCAC was a special purpose acquisition company formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses. In connection with the closing of the SPAC Transaction, HCAC changed its name to "NRC Group Holdings Corp.," and the ticker symbol for its outstanding common stock and warrants trading on the NYSE American exchange changed to "NRCG" and "NRCG.WS," respectively.

        Prior to the closing of the SPAC Transaction, the business and assets of what is now NRCG were owned by JFL Partners or other investment affiliates of J.F. Lehman & Company, LLC ("JFLCo"), including the JFL Entities. Upon the closing of the SPAC Transaction, the JFL Entities beneficially owned approximately 67% of NRCG.

        Prior to the SPAC Transaction, from as early as 2014, JFLCo and its investment affiliates explored potential strategic transactions that would have a substantial impact on the business and stockholder base of the then existing businesses of NRCG. Such potential strategic transactions included high-level preliminary discussions between representatives of JFLCo and its investment affiliates and US Ecology in 2016 and 2017 regarding a potential transaction involving US Ecology and certain of the businesses now owned by NRCG. However, those discussions never involved discussions of any valuation of the businesses and never progressed beyond the preliminary stages.

        On March 2, 2019, James Baumgardner, chairman of the NRCG Board, had telephonic discussions with each of Jeffrey Feeler, chairman of the US Ecology Board and president and chief executive officer of US Ecology, and Simon Bell, executive vice president and chief operating officer of US Ecology, regarding general trends in the industry affecting each of US Ecology and NRCG. The individuals also discussed whether there would be any interest in exploring a potential strategic transaction involving US Ecology and NRCG. JFL Partners nominated Mr. Baumgardner to serve as a member of the NRCG Board pursuant to the NRCG Investor Rights Agreement (as defined herein). In addition, Mr. Baumgardner is a member of the Operating Executive Board of JFLCo, a position he has held since February 2018.

        On March 7, 2019, the US Ecology Board held a regularly scheduled meeting at which Mr. Feeler informed the US Ecology Board on his conversation with Mr. Baumgardner.

        On March 15, 2019, Mr. Feeler contacted Mr. Baumgardner and requested a meeting to further explore NRCG's business, growth opportunities and initial thinking regarding a potential strategic transaction.

        On March 14, 2019, Mr. Feeler, Mr. Bell and other senior representatives of US Ecology met to discuss the business of NRCG and potential strategic fit with US Ecology. At this meeting, it was determined that more information was needed and Mr. Feeler committed to reach out to Mr. Baumgardner to arrange a meeting.

        On March 18, 2019, Mr. Feeler met with Mr. Baumgardner and Glenn Shor, a member of the NRCG Board, to gain a better understanding of NRCG's business, growth opportunities and initial thinking regarding a potential strategic transaction between NRCG and US Ecology. Preliminary, high-level expectations on the valuation of NRCG were discussed, but the parties did not negotiate or agree to any specific valuation. The parties also discussed the possibility that such a transaction may involve mostly ECOL Common Stock as consideration. In addition to serving as a member of the NRCG Board, Mr. Shor is also a partner at JFLCo.

        On March 21, 2019, NRCG and US Ecology executed a confidentiality agreement, providing for the confidential treatment of information of NRCG provided to US Ecology in connection with the parties' exploration of a potential strategic transaction. On March 25, 2019, NRCG and US Ecology executed a confidentiality agreement, providing for the confidential treatment of information of US Ecology provided to NRCG in connection with the parties' exploration of a potential strategic transaction. Following the execution of these confidentiality agreements and through the signing of the Merger Agreement, each of NRCG and US Ecology and their respective advisors, and, with respect to US Ecology, its financing sources, conducted due diligence on the other party.

        On March 25, 2019, US Ecology management telephonically met with representatives of Houlihan Lokey, a financial advisor to US Ecology ("Houlihan"), and Wells Fargo, the administrative agent and a lender under US Ecology's existing credit facility, to discuss a possible strategic transaction involving US Ecology and NRCG.

        On April 1, 2019, certain senior management of US Ecology, including Mr. Feeler; Eric Gerratt, executive vice president, chief financial officer and treasurer, Mr. Bell, executive vice president and chief operating officer; Andrew Marshall, executive vice president of regulatory compliance and safety; Matt Dahl, vice president, corporate planning and development; and a representative of Houlihan, met with Mr. Shor, as well as C. Alexander Harman, a member of the NRCG Board and a partner at JFLCo; Christian Swinbank, a member of the NRCG Board and chief executive officer and president of NRCG; and Joseph Peterson, chief financial officer of NRCG, conducted an informal management meeting to provide an overview of NRCG's business, growth opportunities, strategic plans and other background information. The parties discussed the strategic rationale for a potential strategic transaction, but there was no discussion regarding valuation.

        On April 2, 2019, US Ecology management met with representatives of Houlihan and Wells Fargo to debrief on the matters discussed at the April 1, 2019 meeting.

        On April 3, 2019, the NRCG Board held its regularly scheduled quarterly meeting at NRCG's headquarters in Houston, Texas. During an executive session of the NRCG Board, that included only the non-management members of the NRCG Board, Mr. Shor informed the NRCG Board of his and the other NRCG Board members' and NRCG management's preliminary discussions with US Ecology and that during those preliminary discussions US Ecology had expressed interest in a potential strategic transaction with NRCG, but that material terms, such as price and the specific form and type of consideration, had not yet been discussed, other than the fact that US Ecology indicated that at least part, if not all, of the proposed consideration would likely consist of ECOL Common Stock. Mr. Shor reminded the NRCG Board that US Ecology had evaluated and expressed interest in a potential strategic transaction with certain businesses of NRC Group in the past, including prior to NRC Group's consummation of the SPAC Transaction. After deliberations, the NRCG Board directed Mr. Shor to continue to explore on a preliminary basis a potential strategic transaction with US Ecology.

        Over the course of the next two weeks, as directed by the NRCG Board, Messrs. Baumgardner, Shor and Harman and certain officers of NRCG continued to engage in discussions with representatives of US Ecology regarding a potential strategic transaction.

        On April 10, 2019, Messrs. Feeler, Bell and Dahl and representatives of Houlihan met with Mr. Shor to discuss other potential strategic transactions involving US Ecology.

Table of Contents

        On April 13, 2019, Mr. Feeler and Mr. Baumgardner met to discuss the potential structure and consideration mix for a strategic transaction involving US Ecology and NRCG.

        On April 15, 2019, Mr. Dahl met with representatives of BofA Merrill Lynch to discuss a potential strategic transaction involving US Ecology. US Ecology subsequently engaged BofA Merrill Lynch as an additional financial advisor in connection with the potential transaction involving US Ecology and NRCG.

        Between April 16 and 19, 2019, representatives of US Ecology, in consultation with Houlihan, BofA Merrill Lynch and Dechert, legal counsel to US Ecology, prepared a non-binding indication of interest (the "US Ecology IOI") with respect to US Ecology's proposed acquisition of NRCG. Mr. Feeler individually briefed members of the US Ecology Board regarding the potential opportunity involving a strategic transaction involving NRCG.

        Additionally, in the morning of April 19, 2019, representatives of NRCG management, Mr. Shor, Jones Day, NRCG's regular legal counsel, and Evercore, financial advisor to NRCG, had a telephonic meeting regarding the potential strategic transaction. During that conversation, the parties discussed the potential mix of consideration that could be included in a potential strategic transaction.

        On April 19, 2019, following meetings with its advisors, US Ecology submitted to NRCG the US Ecology IOI to acquire all of the outstanding equity of NRCG for a proposed purchase price of $11.05 per share of NRCG Common Stock, representing, in US Ecology's view, an overall enterprise value of NRCG of $892 million, with the consideration payable in shares of ECOL Common Stock. The proposed purchase price represented a premium of approximately 30.5% to the $8.47 per share closing price of NRCG Common Stock on April 18, 2019, the last trading day prior to the date of the US Ecology IOI. The US Ecology IOI did not address whether the purchase price would be in the form of a fixed or variable exchange ratio. In addition, the US Ecology IOI stated that US Ecology's proposal was subject to, among other things, US Ecology's satisfactory completion of confirmatory due diligence.

        On April 23, 2019, the NRCG Board held a special telephonic meeting to discuss the US Ecology IOI. Mr. Shor reviewed the principal terms of the proposal, noting that the proposal reflected a premium to the then current trading price of NRCG Common Stock of 30.5%. Following discussion of the proposal, Mr. Baumgardner reminded the NRCG Board that he previously served in numerous senior management roles at US Ecology, including serving as president, chief executive officer, chief operating officer, chief financial officer and a member of the board of directors, until his departure in 2012. Mr. Baumgardner indicated that he no longer had any direct or indirect interests, economic or otherwise, in US Ecology and that he had not had any economic interests in US Ecology for a number of years. After deliberations, representatives of Jones Day provided an overview of the fiduciary duties of the NRCG Board and other relevant considerations in evaluating a potential strategic transaction with US Ecology.

        After deliberations, the NRCG Board determined to continue to explore a potential strategic transaction with US Ecology, including to (1) engage in confirmatory due diligence of US Ecology, since the consideration proposed by US Ecology was proposed to comprised solely of shares of ECOL Common Stock and (2) continue to provide information to US Ecology and its representatives, including access to NRCG management, so that US Ecology could perform its confirmatory due diligence. In addition, in order to facilitate the evaluation and negotiation of a potential strategic transaction with US Ecology, the NRCG Board unanimously resolved to create a transaction committee of the NRCG Board (the "Transaction Committee"), to be comprised of Messrs. Baumgardner, Shor and Harman. Such individuals were appointed because of their knowledge of the operations of NRCG and the industry in which it operates, as well as their extensive experience in negotiating strategic transactions. The NRCG Board also appointed Mr. Shor as chairman of the Transaction Committee. The NRCG Board also resolved to formally engage Jones Day as outside legal counsel in connection

with the potential transaction. From its formation on April 23, 2019 through the date on which the Merger Agreement was executed, the Transaction Committee led the evaluation and negotiation on behalf of NRCG for the proposed transaction with US Ecology.

        On April 24, 2019, Messrs. Baumgardner and Feeler spoke by telephone regarding the structure and timeline for the potential transaction involving US Ecology and NRCG.

        On April 25, 2019, at the direction of the Transaction Committee, NRCG formally engaged Evercore to assist it in exploring and negotiating the potential strategic transaction with US Ecology. The Transaction Committee requested that Evercore provide an analysis of exchange ratio mechanics and the use of collar provisions in strategic transactions involving stock consideration, including an overview of collar provisions, so that the Transaction Committee could further assess whether such a provision would be beneficial to NRCG stockholders.

        On May 6, 2019, Evercore provided the Transaction Committee with a summary presentation outlining exchange ratio mechanics and the use of collar provisions, which included an analysis of floating and fixed collar provisions. The analysis noted that collar provisions attempted to minimize the effects of changes in the value of the stock consideration between announcement of the transaction and closing, meaning that while a collar could mitigate the effects on NRCG stockholders of a decrease in the value of ECOL Common Stock prior to closing, it would also limit the ability of NRCG stockholders to benefit from any increase in the value of ECOL Common Stock during such period. After deliberation and discussion, because the Transaction Committee determined that a transaction involving US Ecology and NRCG would likely be viewed favorably by the public markets, the Transaction Committee determined that it would not seek to negotiate for a collar provision so that NRCG stockholders would be able to benefit from any increase in the value of ECOL Common Stock following announcement of the transaction.

        Also on May 6, 2019, Messrs. Feeler, Gerratt and Dahl, together with representatives of Houlihan and BofA Merrill Lynch, met with Messrs. Swinbank and Shor over dinner at the WasteExpo conference in Las Vegas, Nevada to discuss, among other things, the potential strategic transaction between US Ecology and NRCG.

        On May 11, 2019, Mr. Baumgardner contacted Mr. Feeler to discuss the potential strategic transaction involving US Ecology and NRCG, and advised Mr. Feeler that the NRCG Board anticipated an update from US Ecology regarding the status of US Ecology's due diligence, US Ecology's financing commitments and deal certainty in the following seven to ten days.

        On May 14 to May 15, 2019, senior management from NRCG and US Ecology met in Park City, Utah for in-person due diligence meetings. NRCG's financial advisor, Evercore, and US Ecology's financial advisors, Houlihan and BofA Merrill Lynch, also attended these meetings. At those meetings, senior management from each of NRCG and US Ecology presented an overview of their respective businesses. During the remainder of the week of May 13, 2019, senior management from NRCG and US Ecology also toured certain significant operating sites of each of the companies.

        In the afternoon of May 15, 2019, the Transaction Committee had a meeting to discuss the status of the potential strategic transaction with US Ecology. Also present were certain officers of NRCG and representatives of Jones Day. At that meeting, the Transaction Committee noted that NRCG's confirmatory due diligence on US Ecology was substantially complete, that management meetings had been held, and that no issues were identified. The Transaction Committee also directed representatives of Evercore to inform US Ecology's financial advisors that NRCG expected US Ecology to deliver an updated indication of interest with an updated valuation for NRCG reflecting US Ecology's substantial completion of confirmatory due diligence prior to NRCG's upcoming NRCG Board meeting, which was scheduled to occur immediately after NRCG's annual stockholders meeting on May 30, 2019. Following that meeting, representatives of Evercore communicated such expectation to representatives of BofA Merrill Lynch.

        On May 20, 2019, representatives of US Ecology, NRCG and the JFL Entities participated in a call to discuss financial due diligence matters, including certain financial forecasts prepared by US Ecology management summarized in the section entitled "The Mergers—Certain Financial Forecasts Prepared by US Ecology Management." Representatives of US Ecology's and NRCG's financial advisors also attended this call.

        Also on May 20, 2019, Messrs. Feeler and Shor met in person to discuss the potential strategic transaction. At the meeting, Mr. Feeler provided US Ecology's proposed timeline for the potential strategic transaction, including US Ecology's expectation of when the potential strategic transaction could be consummated.

        Also on May 20, 2019, the US Ecology Board held a regularly scheduled meeting. At that meeting, Messrs. Feeler and Dahl updated the US Ecology Board on discussions with representatives of NRCG regarding US Ecology's potential acquisition of NRCG. At that meeting, US Ecology's financial advisors provided the US Ecology Board with an overview of NRCG. Messrs. Feeler and Dahl also discussed with the US Ecology Board the strategic rationale and financial basis for combining the companies.

        In the evening of May 24, 2019, representatives of Dechert and Jones Day had a telephonic meeting to discuss the potential strategic transaction and the timing of the preparation of a draft merger agreement. During that meeting, the parties discussed generally the scope of representations and warranties and certain Jones Act-related considerations in connection with a merger transaction involving US Ecology and NRCG.

        On May 29, 2019, Mr. Feeler telephoned Mr. Shor to inform him that US Ecology was still interested in pursuing a potential strategic transaction with NRCG, but that it needed more time to revise its proposal and anticipated providing its updated valuation to NRCG during the first week of June.

        On May 30, 2019, the NRCG Board held a regularly scheduled in-person meeting following NRCG's annual stockholders' meeting. At that meeting, the NRCG Board reviewed NRCG's operations and financial performance. Also at that meeting, Mr. Shor provided an update on the status of due diligence related to the potential strategic transaction with US Ecology, noting that the parties had conducted in-person meetings in mid-May. Mr. Shor also informed the NRCG Board that the Transaction Committee expected to receive an updated proposal, as well as a draft merger agreement, from US Ecology the following week. The NRCG Board also discussed other opportunities available to NRCG, including potential acquisitions. Later that day, following the NRCG Board meeting, Mr. Shor called a representative of Houlihan to provide an update.

        In the morning of May 31, 2019, representatives of Dechert and Jones Day had a telephonic meeting to discuss the timeline for the delivery of the initial draft merger agreement and the status of legal due diligence.

        In the afternoon of May 31, 2019, the Transaction Committee, together with certain officers of NRCG and representatives of Jones Day, held a telephonic meeting to discuss the status of the proposed transaction with US Ecology. At that meeting, Mr. Shor provided an update on the status of due diligence, document requests and negotiations related to the strategic potential transaction. Representatives of Jones Day provided an update, based on their discussions with representatives of Dechert, on the potential timing for receiving an initial draft of the merger agreement from US Ecology. In addition, the Transaction Committee noted that the US Ecology IOI did not specify whether the exchange ratio to be proposed by US Ecology would be a fixed exchange ratio, a fixed value based on a collar, or some other mechanism. The Transaction Committee reviewed the materials provided by Jones Day and Evercore on exchange ratio mechanics. The Transaction Committee noted that while it would consider the mechanics and structure ultimately proposed by US Ecology in the context of the overall deal terms proposed, the Transaction Committee had a preference for a fixed

76


Table of Contents

exchange ratio so that NRCG stockholders would have the opportunity to participate in any increase in the value of ECOL Common Stock between the announcement and closing of any potential transaction. Also on May 31, 2019, representatives of Dechert spoke with representatives of Richards, Layton & Finger, P.A ("Richards Layton"), which was later engaged as Delaware counsel to US Ecology, regarding various matters pertaining to the transaction structure that would be reflected in the draft merger agreement.

        On June 2, 2019, in accordance with US Ecology's directives, representatives of BofA Merrill Lynch informed representatives of Evercore that US Ecology did not intend to increase its current proposed per share purchase price which, in light of US Ecology's due diligence on NRCG's capital structure, US Ecology still believed represented an increased enterprise value compared to the US Ecology IOI and that, as such, its proposal was to acquire all of the outstanding equity of NRCG based on an implied value of $11.05 per share of NRCG Common Stock at a fixed exchange ratio based on such price per share of NRCG Common Stock and the volume weighted average price of ECOL Common Stock from the date of the US Ecology IOI until the date on which the definitive merger agreement was signed. The proposed purchase price represented a premium of approximately 32.0% to the $8.37 closing price of NRCG Common Stock on May 31, 2019, the last trading day prior to such conversation. Later that evening, US Ecology's position was confirmed by representatives of Houlihan and Mr. Shor. In that conversation, Mr. Shor stated that NRCG was not prepared to further engage in a potential strategic transaction at that valuation.

        On June 4, 2019, Mr. Harman received an unsolicited email communication from a former NRCG executive who had been contacted by a representative of Company A inquiring whether the JFL Entities would be interested in selling its interests in NRCG. The proposal set forth in the email communication from Company A was not for all of the outstanding equity interests in NRCG but limited to only the shares of NRCG Common Stock held by the JFL Entities.

        Also on June 4, 2019, representatives of the JFL Entities had a telephonic meeting with a representative of Company A regarding Company A's proposal. In those discussions, Company A indicated that it was highly interested in pursuing an acquisition of NRCG and may be willing to acquire not only the shares of NRCG Common Stock held by the JFL Entities but, alternatively, all of the outstanding equity interests of NRCG.

        On June 5, 2019, Mr. Shor met with a representative from Houlihan and informed him that a strategic third-party had expressed interest in acquiring interests in NRCG for cash, but that NRCG would be willing to reengage with US Ecology if US Ecology increased its proposed valuation to at least $12.00 per share of NRCG Common Stock.

        In the morning of June 6, 2019, the Transaction Committee, together with certain officers of NRCG and representatives of Jones Day, held a telephonic meeting. At that meeting, the Transaction Committee noted that US Ecology had not been willing to increase its proposed valuation of NRCG and that the Transaction Committee did not believe US Ecology's proposed valuation of $11.05 per share of NRCG Common Stock was adequate. Mr. Harman also informed the Transaction Committee of the unsolicited proposal that the JFL Entities, in their capacity as a stockholder of NRCG, had received from Company A. Mr. Harman informed the Transaction Committee that the JFL Entities were willing to delay making any independent decision on a transaction with Company A until after the Transaction Committee had fully explored a potential strategic transaction with US Ecology. After deliberation, the Transaction Committee resolved to inform US Ecology of the unsolicited proposal from Company A and that the Transaction Committee would be willing to continue to explore a potential strategic transaction exclusively with US Ecology so long as US Ecology increased its proposed valuation to at least $12.00 per share of NRCG Common Stock.

77

        Later that day, Mr. Dahl and a representative from Houlihan telephoned Mr. Shor to inform him that US Ecology was willing to increase its proposed purchase price to an implied value of $12.00 per share of NRCG Common Stock in exchange for JFL Partners waiving its right to any remaining payment obligations (up to $25.0 million) from NRCG under Section 5.18(b) of the 2018 Purchase Agreement, exclusivity through June 24, 2019 and an agreement by NRCG to devote the resources required to promptly address US Ecology's outstanding due diligence requests. The revised proposed purchase price represented a premium of approximately 49.8% to the $8.01 per share closing price of NRCG Common Stock on June 5, 2019, the last trading day prior to the date on which US Ecology increased its proposal.

        In the evening of June 6, 2019, Dechert delivered to Jones Day an initial draft merger agreement, which reflected comments from Richards Layton. The initial draft merger agreement provided that each outstanding share of NRCG Common Stock and NRCG Series A Preferred Stock (taking into account the applicable Fundamental Change Additional Shares, as defined in the NRCG Series A Certificate of Designations), would be exchanged for shares of ECOL Common Stock based on a fixed exchange ratio to be agreed upon between US Ecology and NRCG.

        The initial draft merger agreement contemplated that concurrently with entry into the merger agreement, certain stockholders of NRCG, including all stockholders that are investment affiliates of JFLCo, would enter into a support agreement with US Ecology, which, among other things, would require such stockholders to vote their shares of NRCG Common Stock in favor of adoption of the merger agreement and against alternative transactions. In addition to the support agreement, the initial draft merger agreement contemplated that such stockholders would also enter into an agreement whereby the shares of ECOL Common Stock to be received by them in the potential transaction would be subject to lock-up provisions for a period of time following the closing. In addition, the initial merger agreement contemplated that JFL Partners would waive its right to receive post-closing payments of up to $25 million related to certain remaining contractual obligations of NRCG contemplated by the SPAC Transaction.

        From June 6, 2019 through the date on which the Merger Agreement was executed, Dechert and Jones Day negotiated the terms of the Merger Agreement.

        On June 7, 2019, NRCG and US Ecology executed an exclusivity agreement that granted US Ecology exclusivity to negotiate a strategic transaction with NRCG through 11:59 p.m. Boise, Idaho time on June 24, 2019. Also on June 7, 2019, the Transaction Committee, together with certain officers of NRCG and representatives of Jones Day, held a telephonic meeting to discuss the status of the proposed transaction with US Ecology. Mr. Shor provided the Transaction Committee with an update regarding the mutual due diligence performed by each of NRCG and US Ecology, and he indicated that each of NRCG and US Ecology continued to meet all reasonable due diligence requests made by or on behalf of the other party, including providing access to requested documents and participating in telephonic discussions. Representatives of Jones Day provided the Transaction Committee with a summary regarding the material terms in the initial draft merger agreement, open items and potential changes to such terms. The Transaction Committee then deliberated on the open items and potential changes. The Transaction Committee also noted that US Ecology had proposed a fixed exchange ratio. After reviewing the materials previously provided by Jones Day and Evercore as to various structures and mechanics with respect to exchange ratios, the Transaction Committee determined to accept the fixed exchange ratio structure proposed by US Ecology, as that structure would provide NRCG stockholders with the opportunity to participate in any increase in value of ECOL Common Stock between announcement and closing of any proposed transaction.

        At that meeting, the Transaction Committee also resolved to discuss with US Ecology its willingness to appoint one specified member of the NRCG Board to the US Ecology Board following the completion of the proposed transaction.

78


Table of Contents

        In addition, at that meeting, the Transaction Committee discussed the fact that the initial draft merger agreement provided for the exchange, pursuant to the merger, of all of the outstanding shares of NRCG Series A Preferred Stock into common stock of the surviving corporation. Following such discussion, the Transaction Committee resolved to engage Delaware counsel to advise on the potential transaction and to review and analyze the terms of the merger agreement in relation to the NRCG Series A Preferred Stock.

        Later that day on June 7, 2019, representatives of Jones Day and Dechert had a call to discuss at a high level certain of the provisions included in the initial draft merger agreement, including the treatment of the NRCG Series A Preferred Stock, under Delaware law and the NRCG Series A Certificate of Designations.

        In the morning of June 9, 2019, the US Ecology Board held a telephonic meeting on the status of a potential strategic transaction involving NRCG. After an update from US Ecology management, representatives of Dechert reviewed with the US Ecology Board the US Ecology Board members' responsibilities in considering a strategic transaction with NRCG, including their fiduciary duties under applicable law. In addition, representatives of Dechert provided a high-level overview of the initial draft of the merger agreement, and discussed with the US Ecology Board certain other legal aspects of the potential transaction with NRCG. Also at this meeting, BofA Merrill Lynch reviewed with the US Ecology Board certain preliminary financial analyses and information related to the proposed transaction.

        On June 10, 2019, Jones Day delivered to Dechert a revised draft merger agreement. The revised draft merger agreement indicated that only JFL Partners and its affiliates would enter into a support agreement, and that any such support agreement would need to contain termination provisions consistent with the merger agreement.

        Also on June 10, 2019, NRCG engaged Morris, Nichols, Arsht & Tunnell LLP ("Morris Nichols") as Delaware counsel in connection with the proposed transaction.

        On June 11, 2019, members of the Transaction Committee, along with certain officers of NRCG and representatives of Jones Day, held a telephonic meeting to discuss the proposed transaction, including the treatment of the NRCG Series A Preferred Stock under the revised draft merger agreement, Delaware law and the NRCG Series A Certificate of Designations.

        On June 12, 2019, the Transaction Committee, together with certain officers of NRCG and representatives of Jones Day, held a telephonic meeting to discuss the status of negotiations with US Ecology. During that meeting the Transaction Committee and representatives of Jones Day reported on the status of the mutual due diligence being performed by each of US Ecology and NRCG. Representatives of Jones Day also provided an overview of open points in the revised draft merger agreement. Following the overview from Jones Day, the Transaction Committee engaged in active discussion regarding the proposed transaction, the need for closing certainty following the signing of the proposed merger agreement, and the need for NRCG to continue to operate its business in the ordinary course prior to consummation of the proposed transaction without undue restriction under the merger agreement.

        In the afternoon of June 13, 2019, representatives of Dechert and Jones Day had a telephonic meeting to negotiate the revised draft merger agreement. Among other things, the parties discussed (1) NRCG's right to a fee in the event that the merger agreement were terminated because the proposed transaction failed to be approved by US Ecology's stockholders or due to a breach by US Ecology of its representations, warranties or covenants in the merger agreement, (2) the size of any termination fee, (3) US Ecology's obligations with respect to seeking antitrust approval, (4) the US Ecology's Board ability to change its recommendation, (5) the timing of closing, (6) post-closing governance matters and (7) the proposed transaction structure. Representatives of Dechert also stated

79


Table of Contents

that they did not believe US Ecology was willing to add a member to the US Ecology Board designated by NRCG. In addition, the representatives of Dechert stated that US Ecology and Dechert were still determining whether the transaction would need to include a newly-formed parent company and a merger of US Ecology with a newly created subsidiary in order to effect the necessary changes under the Jones Act with respect to US Ecology's governing documents.

        In the morning of June 15, 2019, the US Ecology Board held a telephonic meeting on the status of the potential transaction involving NRCG. Mr. Feeler noted, among other things, that NRCG had requested a seat on the US Ecology Board, which request was being evaluated in the context of other transaction points, such as a post-closing lock-up agreement with certain stockholders of NRCG, together with a registration rights agreement so that US Ecology could better manage any post-transaction sale of merger consideration received by those stockholders through an underwritten offering.

        On June 16, 2019, Dechert delivered to Jones Day a revised draft merger agreement, which reflected input from Richards Layton and K&L Gates LLP, maritime counsel to US Ecology.

        In the morning of June 17, 2019, the Transaction Committee, together with certain officers of NRCG and representatives of Jones Day, held a telephonic meeting to discuss the revised draft merger agreement as well as the status of negotiations with US Ecology generally. Representatives of Jones Day provided an overview of the open points in the revised draft merger agreement. The Transaction Committee engaged in an active discussion regarding the proposed transaction. Mr. Shor provided the Transaction Committee with an update regarding the proposed transaction, including an update about the expected timing of receipt from US Ecology of the proposed support agreement, as well as an investor agreement containing certain lock-up and standstill provisions and a registration rights agreement containing registration rights in favor of stockholders subject to the lock-up. Mr. Shor noted that US Ecology was proposing the registration rights agreement so that US Ecology would be able to manage, through an underwritten offering, any post-transaction sale of stock consideration received in the transaction by the JFL Entities. Mr. Shor informed the Transaction Committee that US Ecology was not willing to consider NRCG's proposal that one specified member of the NRCG Board serve on the US Ecology Board following the completion of the proposed transaction.

        Later that day, representatives of Jones Day and Dechert held a telephonic meeting to discuss and negotiate certain provisions of the revised draft merger agreement that continued to remain open.

        In the evening of June 17, 2019, Dechert delivered a draft support agreement and a draft investor agreement to Jones Day. During the period from June 17, 2019 to June 23, 2019, drafts of the support agreement and investor agreement were exchanged and negotiated by representatives of Jones Day and Dechert. Among other things, the investor agreement provided that (1) JFL Partners and its affiliates would be prevented from selling or otherwise disposing of the shares of stock consideration received in the transaction for at least 180 days following consummation of the transaction, (2) JFL Partners and its affiliates would be subject to a standstill provision with respect to US Ecology for at least 180 days following the merger, and (3) JFL Partners would waive any rights it may have to up to $25.0 million of additional consideration in connection with the SPAC Transaction.

        In the evening of June 19, 2019, Dechert delivered a draft registration rights agreement and debt commitment letter to Jones Day. During the period from June 19, 2019 to June 23, 2019, drafts of the registration rights agreement and debt commitment letter were exchanged and negotiated by representatives of Jones Day and Dechert.

        Also in the evening of June 19, 2019, Jones Day delivered a draft of the NRCG disclosure letter to Dechert. During the period from June 19, 2019 to June 23, 2019, drafts of the NRCG disclosure letter were exchanged and negotiated by NRCG, US Ecology and their respective legal counsel.

        On June 20, 2019, Messrs. Feeler, Dahl and Shor had multiple conversations regarding NRCG representation on the post-closing US Ecology Board, lock-up arrangements and other stockholder considerations.

        In the morning of June 20, 2019, the Transaction Committee, together with certain officers of NRCG and representatives of Jones Day, held a telephonic meeting to discuss the status of negotiations with US Ecology. Mr. Shor reported to the Transaction Committee his understanding that certain investment affiliates of JFLCo appeared to have reached agreement with US Ecology as to the material terms of the support agreement, investor agreement and registration rights agreement. The Transaction Committee, together with certain officers of NRCG and representatives of Jones Day, discussed NRCG's position with respect to the open points in the revised draft merger agreement.

        Following the Transaction Committee meeting, Jones Day delivered to Dechert a revised draft merger agreement.

        Later in the day on June 20, 2019, the NRCG Board held a special telephonic meeting to discuss the proposed transaction and the status of negotiations with US Ecology. Certain senior management of NRCG and representatives of Jones Day also participated. Mr. Shor reviewed with the NRCG Board the history of negotiations with US Ecology and the terms of US Ecology's proposal, including the fact that US Ecology's proposal was for $12.00 per share of NRCG Common Stock. Following deliberations, representatives of Jones Day indicated to the NRCG Board that (1) the negotiations between US Ecology and NRCG had been customary for the size and scope of the proposed transaction, and (2) there were a few open points in the revised draft merger agreement, but that those issues were not insurmountable and were likely to be resolved soon. Additionally, representatives of Jones Day discussed with the NRCG Board a detailed summary of the terms of the proposed draft merger agreement.

        In the evening of June 21, 2019, in accordance with the directives of NRCG and US Ecology, representatives of Evercore and BofA Merrill Lynch discussed on behalf of NRCG and US Ecology, respectively, the implied value of the fixed exchange ratio for the proposed transaction. As directed by US Ecology, the representatives of BofA Merrill Lynch informed the representatives of Evercore of US Ecology's position that, in light of the June 6 revised proposal, the fixed exchange ratio should be based solely on the closing price of ECOL Common Stock on June 21, 2019. This would result in a fixed exchange ratio of 0.191. Based on the closing prices of NRCG Common Stock and ECOL Common Stock on June 21, 2019 of $8.83 per share and $62.74 per share, respectively, the proposed exchange ratio implied a purchase price of $12.00 per share of NRCG Common Stock, which represented a premium of approximately 35.9% to the closing price of NRCG Common Stock on June 21, 2019. As directed by NRCG, representatives of Evercore countered, on behalf of NRCG, that the fixed exchange ratio should be based on the volume-weighted average price of ECOL Common Stock since the US Ecology IOI, resulting in a the fixed exchange ratio of 0.2008. Based on the closing prices of NRCG Common Stock and ECOL Common Stock on that day, the exchange ratio communicated by Evercore implied a purchase price of $12.60 per share of NRCG Common Stock, which represented a premium of approximately 42.7% to the closing price NRCG Common Stock on June 21, 2019.

        In the early morning of June 22, 2019, the Transaction Committee, together with certain officers of NRCG and representatives of Jones Day and Evercore, held a telephonic meeting to discuss the status of negotiations with US Ecology. Representatives of Jones Day informed the Transaction Committee as to the remaining open points in the draft merger agreement, including as to (1) the amount of the reverse termination fee or expense reimbursement that would be payable to NRCG in the event that the proposed transaction was not consummated due to US Ecology's stockholders rejecting the proposed transaction, (2) US Ecology's financing and the potential effect on the timing of closing, and (3) the final exchange ratio. After deliberations, the Transaction Committee directed Mr. Baumgardner

81


Table of Contents

to discuss the fixed exchange ratio directly with Mr. Feeler. Further, the Transaction Committee directed representatives of Jones Day to agree on behalf of NRCG that (1) US Ecology would not have to close the proposed transaction prior to October 1, 2019 to allow for US Ecology to finalize its financing, and (2) the expense reimbursement payable by US Ecology in the event of a failure of approval of the proposed transactions by US Ecology's stockholders would be equal to NRCG's fees and expenses, capped at 1% of NRCG's enterprise value.

        Following that meeting, on June 22, 2019, Mr. Baumgardner telephoned Mr. Feeler to discuss the fixed exchange ratio and the remaining open points related to the proposed transaction. Mr. Feeler also had a telephonic meeting with Mr. Shor to discuss the open points related to the investor agreement and registration rights agreement. Mr. Feeler informed Mr. Shor that US Ecology would make a best and final proposal on all these matters to NRCG later that day.

        In the early afternoon of June 22, 2019, Mr. Feeler communicated to Mr. Shor that US Ecology's final proposal was (1) a fixed exchange ratio of 0.194, (2) a condition that without US Ecology's approval, closing of the transaction could not occur prior to October 1, 2019, and would need to occur on the first business day of a month and all conditions to closing, including as to the accuracy of NRCG's representations and warranties and whether a material adverse effect had occurred, would be tested only at closing, and (3) expense reimbursement for NRCG of up to 1% of its enterprise value in the event that the merger agreement was terminated because US Ecology stockholders failed to approve the transaction. Based on the closing prices of NRCG and ECOL Common Stock on June 21, 2019, the proposed 0.194 exchange ratio implied a purchase price of $12.17 per share of NRCG Common Stock, which represented a premium of approximately 37.8% to the closing price of NRCG Common Stock on June 21, 2019.

        Following receipt of US Ecology's final proposal, the Transaction Committee, together with certain officers of NRCG and representatives of Jones Day and Evercore, held a telephonic meeting to discuss US Ecology's final proposal. After discussion and deliberation, the Transaction Committee resolved to accept US Ecology's final proposal on merger agreement terms, but directed Mr. Baumgardner to discuss the fixed exchange ratio directly with Mr. Feeler and to seek an increase in the fixed exchange ratio to 0.196. Based on the closing prices of NRCG Common Stock and ECOL Common Stock on June 21, 2019, a 0.196 exchange ratio implied a purchase price of $12.30 per share of NRCG Common Stock, which represented a premium of approximately 39.3% to the closing price of NRCG Common Stock on June 21, 2019 and based on the ECOL Common Stock average share price over the last 15-trading days represented a price of $12.00 per share of NRCG Common Stock.

        Following that meeting, Mr. Baumgardner telephoned Mr. Feeler to discuss US Ecology's final proposal. Mr. Baumgardner informed Mr. Feeler that NRCG would accept US Ecology's final proposal provided the fixed exchange ratio was 0.196, which Mr. Feeler accepted, subject to US Ecology Board approval.

        Following that discussion, in the afternoon of June 22, 2019, Dechert delivered to Jones Day a revised draft merger agreement. In order to accommodate the changes required by the Jones Act to be incorporated into US Ecology's governing documents, the revised draft merger agreement also contemplated that a new parent company (Holdco) would be formed and that each of US Ecology and NRCG would merge with a subsidiary of such new parent.

        Following discussions and negotiations among representatives of Dechert and Jones Day through the afternoon and evening of June 22, 2019, Jones Day sent a revised draft merger agreement to Dechert. Shortly thereafter, representatives of Dechert telephoned representatives of Jones Day to discuss the revised draft merger agreement. From June 22, 2019 through execution of the Merger Agreement, representatives of Jones Day and Dechert finalized the merger agreement.

        In the morning of June 23, 2019, the US Ecology Board held a telephonic meeting to consider and vote on the proposed final Merger Agreement. At that meeting, US Ecology management provided an overview of management's rationale for the proposed transaction and a summary of the due diligence activities conducted by or on behalf of US Ecology and the key due diligence findings. US Ecology management also updated the US Ecology Board regarding its negotiations with the management of NRCG and requested approval for the NRCG Exchange Ratio of 0.196. At the meeting, representatives of Dechert presented to the US Ecology Board on certain due diligence matters and representatives of K&L Gates provided an overview of maritime laws that would apply to US Ecology following the completion of the Mergers. Representatives of Dechert provided an overview of the structure of the proposed transaction and a summary of the material terms of the Merger Agreement, as well as the revisions to the Merger Agreement since the June 9, 2019 meeting of the US Ecology Board.

        Following the presentation from Dechert, BofA Merrill Lynch reviewed its financial analysis of the NRCG Exchange Ratio provided for in the NRCG Merger in respect of shares of NRCG Common Stock and rendered an oral opinion, confirmed by delivery of a written opinion dated June 23, 2019, to the US Ecology Board to the effect that, as of that date and based on and subject to various assumptions made, procedures followed, matters considered and limitations and qualifications described in the opinion, the NRCG Exchange Ratio provided for in the NRCG Merger in respect of shares of NRCG Common Stock was fair, from a financial point of view, to US Ecology.

        Following an executive session of the independent directors of US Ecology, the discussions described above and considering each of the factors described below in "The Mergers—Reasons for the Merger; Recommendation of the Board of Directors," the US Ecology Board unanimously approved the Merger Agreement and the transactions contemplated thereby, and recommended that US Ecology's stockholders vote to adopt the Merger Agreement, approve the issuance of shares of Holdco Common Stock in connection with the Mergers and approve an amendment to the charter of Holdco to include certain provisions intended to facilitate Holdco's compliance with the U.S. citizenship requirements of the Jones Act that are not included in the current charter of US Ecology.

        In the afternoon of June 23, 2019, the Transaction Committee held a telephonic meeting. The purpose of the meeting was for the Transaction Committee to consider and vote on its recommendation to the NRCG Board regarding the proposed final draft Merger Agreement. Certain officers of NRCG and representatives of Jones Day, Morris Nichols and Evercore also participated in the meeting. Representatives of Jones Day reviewed the responsibilities of the Transaction Committee. Representatives of Jones Day also reviewed the fiduciary duties of the NRCG Board. As part of that presentation, representatives of Jones Day noted for the Transaction Committee the record of events that led up to the meeting. Representatives of Jones Day also presented a summary of the principal terms of the proposed final draft Merger Agreement.

        Following the presentation from Jones Day, representatives of Evercore presented Evercore's financial analysis with respect to the proposed transaction, including a review of the methodologies used in performing such analysis, and a draft fairness opinion prepared by Evercore. Representatives of Evercore then verbally informed the Transaction Committee that it was Evercore's opinion that, as of that date and based upon and subject to the assumptions, limitations, qualifications and conditions described in the draft fairness opinion, the fixed exchange ratio equal to 0.196 contemplated in the proposed final draft Merger Agreement, was fair, from a financial point of view, to the holders of NRCG Common Stock.

        Following the conclusion of the various presentations described above, the Transaction Committee unanimously recommended that the NRCG Board approve the final Merger Agreement, the Support Agreement, the Investor Agreement and the Registration Rights Agreement and recommend that the NRCG common stockholders adopt the Merger Agreement.

        Following the conclusion of the meeting of the Transaction Committee, the NRCG Board held a telephonic meeting. The purpose of the meeting was for the NRCG Board to consider and vote on the approval of the proposed final Merger Agreement and recommend that NRCG common stockholders adopt the proposed final Merger Agreement. Certain officers of NRCG and representatives of Evercore, Jones Day and Morris Nichols also participated in the meeting. Mr. Shor informed the NRCG Board that the Transaction Committee had just concluded a meeting at which the Transaction Committee reviewed the terms of the proposed Merger Agreement, including a presentation on the same by Jones Day, and reviewed a financial analysis and fairness opinion prepared by Evercore noting that, as of that date and based upon and subject to the assumptions, limitations, qualifications and conditions described in the draft fairness opinion, the fixed exchange ratio equal to 0.196 contemplated in the proposed final draft Merger Agreement was in Evercore's opinion fair, from a financial point of view, to the holders of NRCG Common Stock. Mr. Shor stated that following those presentations, and after deliberations, the Transaction Committee unanimously recommended that the NRCG Board approve the proposed final Merger Agreement, the Support Agreement, the Investor Agreement and the Registration Rights Agreement and recommend that NRCG common stockholders adopt the Merger Agreement. Representatives of Jones Day provided the NRCG Board with the same presentation that it gave to the Transaction Committee, as described above.

        Following the presentation from Jones Day, the NRCG Board discussed the treatment of the NRCG Series A Preferred Stock as contemplated by the proposed Merger Agreement, under Delaware law, and the governing documents of NRCG.

        After such discussion, representatives of Evercore provided the NRCG Board with the same presentation that it gave to the Transaction Committee, as described above. Additionally, Evercore provided the NRCG Board with a written opinion to the effect that, as of that date and based upon and subject to the assumptions, limitations, qualifications and conditions described in such written opinion, the fixed exchange ratio equal to 0.196 contemplated in the proposed final draft Merger Agreement was fair, from a financial point of view, to the holders of NRCG Common Stock, as more fully described in the section entitled "The Mergers—Opinion of NRCG's Financial Advisor." Following such presentation, representatives of Evercore responded to various questions from the members of the NRCG Board regarding its financial analysis and fairness opinion.

        Following the conclusion of the various presentations, the discussions described above and considering each of the factors described below in "The Mergers—Reasons for the Merger; Recommendation of the Board of Directors," including a discussion of the risks and benefits of NRCG continuing to operate as an independent public company in its current configuration, pursuing acquisitions as an independent public company and pursuing alternative strategic transactions with strategic or financial buyers, the NRCG Board determined that the Merger Agreement is fair to and in the best interests of NRCG and holders of NRCG Common Stock. The NRCG Board approved the Merger Agreement, the Support Agreement, the Investor Agreement and the Registration Rights Agreement and resolved to recommend that holders of NRCG Common Stock approve the Merger Agreement, by a vote of eight to one, with John Rapaport, the NRCG Series A Preferred Stock director designee, dissenting.

        Prior to dissenting, Mr. Rapaport expressed his concern as to the treatment of the NRCG Series A Preferred Stock as contemplated by the proposed Merger Agreement and indicated that he would prefer to have more time to assess that proposed structure as well as the financial analysis prepared by Evercore. The remaining directors carefully considered the concern and preferences of Mr. Rappaport. After deliberations, including noting the extensive and involved work performed by the Transaction Committee and the analysis provided by Evercore, Jones Day and Morris Nichols, each of the other directors voted in favor of approving the Merger Agreement and determined that the NRCG Merger contemplated by the Merger Agreement is in the best interests of NRCG and the holders of NRCG Common Stock.

US Ecology's Reasons for the Mergers; Recommendation of the US Ecology Board

        As part of its ongoing efforts to strengthen US Ecology's competitive position, further strategic objectives and business opportunities and enhance stockholder value, the US Ecology Board and management team regularly evaluates various potential strategic opportunities for US Ecology. In considering potential strategic opportunities, the US Ecology Board takes into account various factors, including potential synergy opportunities, geographic diversification, integration and likelihood that such opportunities could be executed and be value enhancing for US Ecology's stockholders.

        In evaluating the Mergers, the US Ecology Board consulted with US Ecology's management and legal and financial advisors and, in reaching its decision to approve the Merger Agreement and recommend the adoption by US Ecology stockholders of the US Ecology Merger Agreement Proposal, the Holdco Stock Issuance Proposal and the Holdco Charter Amendment Proposal, the US Ecology Board considered a number of factors (which are not in any relative order of importance) and a substantial amount of information, including the following:

        The US Ecology Board also weighed the factors described above against a number of risks and other factors identified in its deliberations as weighing negatively against the Mergers:

Table of Contents

        The US Ecology Board also was apprised of certain interests in the Mergers of US Ecology's directors and executive officers that may be different from, or in addition to, the interests of US Ecology's stockholders generally as discussed in "The Mergers—Interests of US Ecology Directors and Executive Officers."

        In reaching its decision to approve and declare advisable the Merger Agreement, the Mergers and the other transactions contemplated by the Merger Agreement and recommend that US Ecology stockholders vote in favor of the US Ecology Merger Agreement Proposal, the US Ecology Board held multiple meetings, consulted with US Ecology's senior management and its outside legal and financial advisors, and considered the business, assets and liabilities, results of operations, financial performance, strategic direction and prospects of US Ecology and NRCG. The US Ecology Board concluded that the potentially negative factors associated with the proposed Mergers were significantly outweighed by the potential benefits that it expected US Ecology to achieve as a result of the Mergers. After weighing the various factors described above, the US Ecology Board unanimously voted in favor of the adoption of the Merger Agreement and determined that the Mergers were in the best interests of US Ecology and its stockholders.

        This discussion of the information and factors considered by the US Ecology Board in reaching its conclusions and recommendation summarizes the material factors considered by the US Ecology Board, but is not intended to be exhaustive. In view of the wide variety of factors considered in connection with its evaluation of the Merger Agreement and the transactions contemplated thereby and the complexity of these matters, the US Ecology Board did not find it practicable, and did not attempt, to

quantify, rank or assign any relative or specific weights to the various factors that it considered in reaching its determination to approve the Merger Agreement and to recommend that US Ecology stockholders vote in favor of the US Ecology Merger Agreement Proposal, the Holdco Stock Issuance Proposal and the Holdco Charter Amendment Proposal.

        The US Ecology Board conducted an overall review of the factors described above and considered the factors overall to be favorable to and to support its determination. In considering the factors described above, individual members of the US Ecology Board may have given differing weights to different factors.

        This explanation of the US Ecology Board's reasons for recommending the adoption of the Merger Agreement and other information presented in this section is forward-looking in nature and, therefore, should be read in light of the factors described in the section entitled "Cautionary Statement Regarding Forward-Looking Statements."

        The US Ecology Board determined that the Mergers are fair to and in the best interests of US Ecology and its stockholders and approved the Merger Agreement. The US Ecology Board recommends that US Ecology stockholders vote "FOR" the US Ecology Merger Agreement Proposal, the Holdco Stock Issuance Proposal and the Holdco Charter Amendment Proposal.

Opinion of US Ecology's Financial Advisor

        US Ecology engaged BofA Merrill Lynch as a financial advisor in connection with the Mergers. BofA Merrill Lynch is an internationally recognized investment banking firm which is regularly engaged in the valuation of businesses and securities in connection with mergers and acquisitions, negotiated underwritings, secondary distributions of listed and unlisted securities, private placements and valuations for corporate and other purposes. US Ecology selected BofA Merrill Lynch to act as a financial advisor in connection with the Mergers on the basis of BofA Merrill Lynch's experience in similar transactions, its reputation in the investment community and its familiarity with US Ecology and its business.

        At the June 23, 2019 meeting of the US Ecology Board held to evaluate the Mergers, BofA Merrill Lynch rendered an oral opinion, confirmed by delivery of a written opinion dated June 23, 2019, to the US Ecology Board to the effect that, as of that date and based on and subject to various assumptions made, procedures followed, matters considered and limitations and qualifications described in the opinion, the NRCG Exchange Ratio provided for in the NRCG Merger in respect of shares of NRCG Common Stock was fair, from a financial point of view, to US Ecology.

        The full text of BofA Merrill Lynch's written opinion, dated June 23, 2019, delivered to the US Ecology Board is attached as Annex H to this joint proxy statement/prospectus and is incorporated by reference herein in its entirety. The written opinion sets forth, among other things, the assumptions made, procedures followed, matters considered and limitations and qualifications on the review undertaken by BofA Merrill Lynch in rendering its opinion. The following summary of BofA Merrill Lynch's opinion is qualified in its entirety by reference to the full text of the opinion. BofA Merrill Lynch delivered its opinion for the benefit and use of the US Ecology Board (in its capacity as such) in connection with and for purposes of its evaluation of the Mergers. BofA Merrill Lynch expressed no opinion or view as to any terms or other aspects or implications of the Mergers (other than the NRCG Exchange Ratio to the extent expressly specified in such opinion) and no opinion or view was expressed as to the relative merits of the Mergers in comparison to other strategies or transactions that might be available to US Ecology or in which US Ecology might engage or as to the underlying business decision of US Ecology to proceed with or effect the Mergers. BofA Merrill Lynch expresses

96


Table of Contents

no opinion or recommendation as to how any securityholder should vote or act in connection with the Mergers or any other matter.

        In connection with its opinion, BofA Merrill Lynch, among other things:

        In arriving at its opinion, with the consent of US Ecology, BofA Merrill Lynch assumed and relied upon, without independent verification, the accuracy and completeness of the financial and other information and data publicly available or provided to or otherwise reviewed by or discussed with BofA Merrill Lynch and relied upon the assurances of the managements of US Ecology and NRCG that they were not aware of any facts or circumstances that would make such information or data inaccurate or misleading in any material respect. Based on the assessments of the management of US Ecology as to the relative likelihood of achieving the future financial results reflected in the NRCG forecasts and the

97


Table of Contents

US Ecology-NRCG forecasts, BofA Merrill Lynch relied, at the direction of US Ecology, on the US Ecology-NRCG forecasts in evaluating NRCG for purposes of its analyses and opinion. With respect to the US Ecology-NRCG forecasts, the US Ecology forecasts and the synergies, BofA Merrill Lynch was advised by US Ecology, and BofA Merrill Lynch assumed, at the direction of US Ecology, that they were reasonably prepared on bases reflecting the best currently available estimates and good faith judgments of the management of US Ecology as to, and were a reasonable basis upon which to evaluate, the future financial performance of NRCG and US Ecology, such synergies and the other matters covered thereby. At the direction of US Ecology, BofA Merrill Lynch also relied on the assessments of the management of US Ecology as to US Ecology's ability to achieve the synergies and BofA Merrill Lynch assumed that such synergies would be realized in the amounts and at the times projected.

        At the direction of US Ecology, BofA Merrill Lynch relied upon the assessments of the management of US Ecology as to, among other things, (i) the potential impact on NRCG and US Ecology of certain market, seasonal, cyclical, competitive, geopolitical and macroeconomic and other trends and developments in and prospects for, and governmental, regulatory and legislative matters relating to or otherwise affecting, the environmental, waste and industrial services industry and the markets and geographic regions in which NRCG and US Ecology operate, (ii) certain accounting matters relating to NRCG, including with respect to NRCG's internal controls over financial reporting and remediation of material weaknesses in such controls, (iii) matters relating to prior acquisitions and predecessor companies of NRCG and US Ecology, as applicable, including as to financial aspects involved, ongoing obligations, if any, integration and other financial effects, (iv) existing and future agreements and arrangements involving, and the ability to attract, retain and/or replace, key employees, third-party contractors and other commercial relationships of NRCG and US Ecology, including as to pending and contemplated multi-year, non-recurring and other projects, and (v) the ability to integrate the operations of NRCG and US Ecology. BofA Merrill Lynch assumed, with the consent of US Ecology, that there would be no developments with respect to any such matters that would have an adverse effect on NRCG, US Ecology, Holdco or the Mergers (including the contemplated benefits thereof) or that otherwise would be meaningful in any respect to BofA Merrill Lynch's analyses or opinion.

        BofA Merrill Lynch did not make and was not provided with any independent evaluation or appraisal of the assets or liabilities (contingent, off-balance sheet, accrued, derivative or otherwise) of NRCG, US Ecology, Holdco or any other entity, nor did BofA Merrill Lynch make any physical inspection of the properties or assets of NRCG, US Ecology, Holdco or any other entity. BofA Merrill Lynch was not requested to make, and did not make, an independent evaluation of, and BofA Merrill Lynch expressed no opinion or view as to, any pending or potential litigation, claims or governmental, regulatory or other proceedings, actions or investigations or possible unasserted claims or other contingent liabilities affecting NRCG, US Ecology, Holdco or any other entity. BofA Merrill Lynch did not evaluate the solvency or fair value of NRCG, US Ecology, Holdco or any other entity under any state, federal or other laws relating to bankruptcy, insolvency or similar matters. BofA Merrill Lynch assumed, at the direction of US Ecology, that the Mergers would be consummated in accordance with their respective terms and in compliance with all applicable laws, documents and other requirements, without waiver, modification or amendment of any material term, condition or agreement, and that, in the course of obtaining the necessary governmental, regulatory and other approvals, consents, releases and waivers for the Mergers, no delay, limitation, restriction or condition, including any divestiture requirements or amendments or modifications, would be imposed or occur that would have an adverse effect on NRCG, US Ecology, Holdco or the Mergers (including the contemplated benefits thereof) or that otherwise would be meaningful in any respect to BofA Merrill Lynch's analyses or opinion. BofA Merrill Lynch also assumed, at the direction of US Ecology, that the Mergers would qualify for federal income tax purposes as reorganizations under the provisions of Section 368(a) or together as an exchange within the meaning of Section 351 of the Code and otherwise would qualify for the tax

treatment contemplated by the Merger Agreement. BofA Merrill Lynch further assumed, at the direction of US Ecology, that the final executed Merger Agreement would not differ in any material respect from the draft reviewed by BofA Merrill Lynch.

        BofA Merrill Lynch expressed no opinion or view as to any terms or other aspects or implications of the Mergers (other than the NRCG Exchange Ratio to the extent expressly specified in its opinion), including, without limitation, the form or structure of the Mergers or any terms, aspects or implications of the amended and restated certificate of incorporation of Holdco or any support agreement, investor agreement, registration rights agreement or other agreements, arrangements or understandings entered into in connection with, related to or contemplated by the Mergers or otherwise. BofA Merrill Lynch's opinion was limited to the fairness, from a financial point of view, to US Ecology of the NRCG Exchange Ratio provided for in the NRCG Merger in respect of shares of NRCG Common Stock and no opinion or view was expressed with respect to any consideration received in connection with the Mergers by the holders of any class of securities, creditors or other constituencies of any party. In addition, BofA Merrill Lynch expressed no opinion or view with respect to the fairness (financial or otherwise) of the amount, nature or any other aspect of any compensation or other consideration to any of the officers, directors or employees of any party to the Mergers or any related entities, or class of such persons, relative to the NRCG Exchange Ratio or otherwise. Furthermore, BofA Merrill Lynch expressed no opinion or view as to the relative merits of the Mergers in comparison to other strategies or transactions that might be available to US Ecology or in which US Ecology might engage or as to the underlying business decision of US Ecology to proceed with or effect the Mergers. BofA Merrill Lynch did not express any opinion as to what the value of Holdco Common Stock actually would be when issued or the prices at which Holdco Common Stock, ECOL Common Stock, NRCG Common Stock or any other securities may trade or otherwise be transferable at any time, including following announcement or consummation of the Mergers. BofA Merrill Lynch also expressed no opinion or view with respect to accounting, tax, legal, regulatory or similar matters, including, without limitation, as to tax or other consequences of the Mergers or otherwise or changes in, or the impact of, accounting standards or tax and other laws, regulations and governmental and legislative policies affecting US Ecology, NRCG, Holdco or the Mergers, as to which BofA Merrill Lynch understood such advice was obtained as deemed necessary from qualified professionals, and BofA Merrill Lynch relied, at the direction of US Ecology, upon the assessments of representatives of US Ecology and NRCG as to such matters. In addition, BofA Merrill Lynch expressed no opinion or recommendation as to how any securityholder should vote or act in connection with the Mergers or any other matter.

        BofA Merrill Lynch's opinion was necessarily based on financial, economic, monetary, market and other conditions and circumstances as in effect on, and the information made available to BofA Merrill Lynch as of, the date of BofA Merrill Lynch's opinion. As the US Ecology Board was aware, the credit, financial and stock markets have experienced and continue to experience volatility and BofA Merrill Lynch expressed no opinion or view as to any potential effects of such volatility on US Ecology, NRCG, Holdco or the Mergers. It should be understood that subsequent developments may affect BofA Merrill Lynch's opinion, and BofA Merrill Lynch does not have any obligation to update, revise or reaffirm its opinion. The issuance of BofA Merrill Lynch's opinion was approved by a fairness opinion review committee of BofA Merrill Lynch. Except as described in this summary, US Ecology imposed no other instructions or limitations on the investigations made or procedures followed by BofA Merrill Lynch in rendering its opinion.

        In connection with its opinion, BofA Merrill Lynch performed a variety of financial and comparative analyses, including those described below. The summary of the analyses below and certain factors considered is not a comprehensive description of all analyses undertaken or factors considered by BofA Merrill Lynch. The preparation of a financial opinion or analysis is a complex process involving various determinations as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances and, therefore, a financial opinion

and analyses are not readily susceptible to summary description. BofA Merrill Lynch believes that the analyses and factors summarized below must be considered as a whole and in context. BofA Merrill Lynch further believes that selecting portions of its analyses and factors or focusing on information presented in tabular format, without considering all analyses and factors or the narrative description of the analyses and factors, could create a misleading or incomplete view of the processes underlying BofA Merrill Lynch's analyses and opinion.

        In performing its financial analyses, BofA Merrill Lynch considered industry performance, general business and economic conditions and other matters, many of which are beyond the control of US Ecology and NRCG. The estimates of the future performance of NRCG and US Ecology and other estimates in or underlying BofA Merrill Lynch's analyses are not necessarily indicative of actual values or actual future results, which may be significantly more or less favorable than those estimates or those suggested by such analyses. These analyses were prepared solely as part of BofA Merrill Lynch's analysis of the fairness, from a financial point of view, to US Ecology of the NRCG Exchange Ratio provided for in the NRCG Merger in respect of shares of NRCG Common Stock and were provided to the US Ecology Board in connection with the delivery of BofA Merrill Lynch's opinion. The analyses do not purport to be appraisals or to reflect the prices at which a company might actually be sold or the prices at which any securities have traded or may trade at any time in the future. Accordingly, the estimates used in, and the reference ranges resulting from, any particular analysis described below are inherently subject to substantial uncertainty and should not be taken as the views of BofA Merrill Lynch regarding the actual value of NRCG, US Ecology or otherwise.

        The type and amount of consideration payable in the Mergers was determined through negotiations between US Ecology and NRCG, rather than by any financial advisor, and was approved by the US Ecology Board. The decision of US Ecology to enter into the Merger Agreement was solely that of the US Ecology Board. BofA Merrill Lynch's opinion and analyses were only one of many factors considered by the US Ecology Board in its evaluation of the Mergers and should not be viewed as determinative of the views of the US Ecology Board, US Ecology management or any other person with respect to the Mergers or the NRCG Exchange Ratio.

Financial Analyses

        The discussion set forth below under this heading "—Financial Analyses" is a summary of the material financial analyses provided by BofA Merrill Lynch in connection with its opinion, dated June 23, 2019, to the US Ecology Board. The financial analyses summarized below include information presented in tabular format. In order to fully understand the financial analyses performed by BofA Merrill Lynch, the tables must be read together with the text of each summary. The tables alone do not constitute a complete description of the financial analyses performed by BofA Merrill Lynch. Considering the data set forth in the tables below without considering the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of the financial analyses performed by BofA Merrill Lynch. Future results may differ from those described and such differences may be material. The order in which the financial analyses summarized below appear does not necessarily reflect the relative importance or weight given to such analyses. For purposes of the financial analyses described below, implied per share equity value reference ranges, other than high and low stock prices and stock price targets, are rounded to the nearest $0.05. In calculating implied exchange ratio reference ranges as reflected in such analyses, BofA Merrill Lynch (a) compared the low-end of the approximate implied per share equity value reference ranges derived for NRCG from such analyses to the high-end of the approximate implied per share equity value reference ranges derived for US Ecology from such analyses in order to calculate the low-end of the implied exchange ratio reference ranges and (b) compared the high-end of the approximate implied per share equity value reference ranges derived for NRCG from such analyses to the low-end of the approximate implied per share equity value

        BofA Merrill Lynch reviewed, among other information and to the extent meaningful, enterprise values, calculated as fully diluted equity values based on closing stock prices on June 21, 2019 plus total debt, preferred equity and non-controlling interests (as applicable) and less cash and cash equivalents and marketable securities (as applicable), as a multiple of calendar year 2019 and calendar year 2020 estimated earnings before interest, taxes, depreciation and amortization, inclusive of stock-based compensation expense and excluding certain non-recurring items, as applicable (referred to as "adjusted EBITDA"). Financial data of the selected companies were based on publicly available research analysts' estimates, public filings and other publicly available information and calendarized (as applicable) for comparative purposes. Financial data of NRCG was based on the US Ecology-NRCG forecasts, publicly available research analysts' estimates and public filings.

        The overall low to high calendar year 2019 and calendar year 2020 estimated adjusted EBITDA multiples observed for the NRCG selected companies were 6.9x to 11.5x (with an overall mean of 8.8x and median of 8.0x) and 6.3x to 10.9x (with an overall mean of 8.0x and median of 7.3x), respectively, with low to high calendar year 2019 and calendar year 2020 estimated adjusted EBITDA multiples for the selected environmental services companies of 6.9x to 11.5x (with a mean of 10.1x and a median of 10.7x) and 6.3x to 10.9x (with a mean of 9.2x and a median of 9.6x), respectively, and low to high calendar year 2019 and calendar year 2020 estimated adjusted EBITDA multiples for the selected industrial services companies of 7.0x to 9.2 (with a mean of 7.9x and a median of 7.7x) and 6.8x to 7.5x (with a mean of 7.1x and a median of 7.0x), respectively.

        BofA Merrill Lynch then applied selected ranges derived from the selected companies of calendar year 2019 and calendar year 2020 estimated adjusted EBITDA multiples of 7.5x to 10.5x and 7.0x to

        BofA Merrill Lynch reviewed, among other information, enterprise values, calculated as fully diluted equity values based on closing stock prices on June 21, 2019 plus total debt, preferred equity and non-controlling interests (as applicable) and less cash and cash equivalents and marketable securities (as applicable), as a multiple of calendar year 2019 and calendar year 2020 estimated adjusted EBITDA. Financial data of the selected companies were based on publicly available research analysts' estimates, public filings and other publicly available information and calendarized (as applicable) for comparative purposes. Financial data of US Ecology was based on the US Ecology forecasts, publicly available research analysts' estimates and public filings.

        The overall low to high calendar year 2019 and calendar year 2020 estimated adjusted EBITDA multiples observed for the US Ecology selected companies were 6.9x to 16.9x (with an overall mean of 12.5x and median of 11.5x) and 6.3x to 15.6x (with an overall mean of 11.6x and median of 10.9x), respectively, with low to high calendar year 2019 and calendar year 2020 estimated adjusted EBITDA multiples for the selected environmental services companies of 6.9x to 11.5x (with a mean of 10.1x and a median of 10.7x) and 6.3x to 10.9x (with a mean of 9.2x and a median of 9.6x), respectively, and low to high calendar year 2019 and calendar year 2020 estimated adjusted EBITDA multiples for the selected waste services companies of 11.1x to 16.9 (with a mean of 13.9x and a median of 13.6x) and 10.5x to 15.6x (with a mean of 12.9x and a median of 12.6x), respectively.

        BofA Merrill Lynch then applied selected ranges derived from the selected companies of calendar year 2019 and calendar year 2020 estimated adjusted EBITDA multiples of 10.5x to 13.5x and 9.5x to 12.5x, respectively, to corresponding data of US Ecology based on the US Ecology forecasts. This analysis indicated approximate implied per share equity value reference ranges for US Ecology, based on calendar year 2019 and calendar year 2020 estimated adjusted EBITDA, of $51.45 to $70.15 and $47.90 to $67.45, respectively.

        Utilizing the approximate implied per share equity value reference ranges derived for NRCG and US Ecology described above, BofA Merrill Lynch calculated the following approximate implied

exchange ratio reference ranges, as compared to the NRCG Exchange Ratio provided for in the NRCG Merger in respect of shares of NRCG Common Stock:

Approximate Implied Exchange Ratio
Reference Ranges Based On:
   
  NRCG Exchange Ratio
FY 2019E Adjusted EBITDA   FY 2020E Adjusted EBITDA
0.120x - 0.282x   0.138x - 0.306x   0.196x

        No company used in the analyses is identical or directly comparable to NRCG or US Ecology. Accordingly, an evaluation of the results of this analysis is not entirely mathematical. Rather, the analyses involve complex considerations and judgments concerning differences in financial and operating characteristics and other factors that could affect the public trading or other values of the companies to which NRCG and US Ecology were compared.

        Discounted Cash Flow Analyses.    BofA Merrill Lynch performed separate discounted cash flow analyses of NRCG and US Ecology.

        NRCG.    BofA Merrill Lynch performed a discounted cash flow analysis of NRCG by calculating the estimated present value (as of June 30, 2019) of the standalone unlevered, after-tax free cash flows that NRCG was forecasted to generate during the second half of the fiscal year ending December 31, 2019 through the full fiscal year ending December 31, 2023 based on the US Ecology-NRCG forecasts. BofA Merrill Lynch calculated terminal values for NRCG by applying a selected range of adjusted EBITDA exit multiples of 8.5x to 10.0x to NRCG's terminal year estimated adjusted EBITDA. The cash flows and terminal values were then discounted to present value (as of June 30, 2019) using a selected range of discount rates of 7.25% to 8.75%. This analysis indicated an approximate implied per share equity value reference range for NRCG of $14.25 to $17.60.

        US Ecology.    BofA Merrill Lynch performed a discounted cash flow analysis of US Ecology by calculating the estimated present value (as of June 30, 2019) of the standalone unlevered, after-tax free cash flows that US Ecology was forecasted to generate during the second half of the fiscal year ending December 31, 2019 through the full fiscal year ending December 31, 2023 based on the US Ecology forecasts. For purposes of this analysis, stock-based compensation was treated as a cash expense. BofA Merrill Lynch calculated terminal values for US Ecology by applying a selected range of adjusted EBITDA exit multiples of 10.5x to 12.0x to US Ecology's terminal year estimated adjusted EBITDA. The cash flows and terminal values were then discounted to present value (as of June 30, 2019) using a selected range of discount rates of 6.50% to 8.25%. This analysis indicated an approximate implied per share equity value reference range for US Ecology of $61.05 to $76.05.

        Utilizing the approximate implied per share equity value reference ranges derived for NRCG and US Ecology described above, BofA Merrill Lynch calculated the following approximate implied exchange ratio reference range, as compared to the NRCG Exchange Ratio provided for in the NRCG Merger in respect of shares of NRCG Common Stock:

Approximate Implied Exchange Ratio Reference Range
  NRCG Exchange Ratio

0.187x - 0.288x

  0.196x

Certain Additional Information

        BofA Merrill Lynch observed certain additional information that was not considered part of its financial analyses for its opinion but was noted for informational purposes, including the following:

        Relative Contributions.    BofA Merrill Lynch reviewed the relative contributions of US Ecology and NRCG to, among other things, the combined company's calendar years 2019 through 2021 estimated

103


Table of Contents

adjusted EBITDA, without taking into account potential synergies anticipated by US Ecology management to result from the Mergers, based on the US Ecology forecasts and US Ecology-NRCG forecasts. This review indicated overall implied relative equity contributions of US Ecology and NRCG, taking into account the standalone capital structures of US Ecology and NRCG, of approximately 61.5% to 63.8% and 36.2% to 38.5%, respectively, to the combined company's estimated adjusted EBITDA during calendar years 2019 through 2021 and an approximate implied overall exchange ratio reference range based on such relative contributions of 0.251x to 0.274x. BofA Merrill Lynch noted that, based on the NRCG Exchange Ratio, the pro forma ownership of holders of ECOL Common Stock and NRCG Common Stock in the combined company upon consummation of the Mergers would be approximately 69.7% and 30.3%, respectively.

        Has/Gets.    BofA Merrill Lynch reviewed the illustrative pro forma impact of the Mergers on the implied per share equity value of US Ecology based on the US Ecology forecasts and the US Ecology-NRCG forecasts and utilizing the methodologies described above under "—Discounted Cash Flow Analyses," after taking into account the potential synergies and costs to achieve such synergies anticipated by US Ecology management to result from the Mergers, which indicated that the Mergers could have a positive impact on the implied per share equity value of US Ecology relative to US Ecology's implied per share equity value on a standalone basis.

        Other.    BofA Merrill Lynch also observed the following:

Miscellaneous

        US Ecology has agreed to pay BofA Merrill Lynch for its services as financial advisor to US Ecology in connection with the Mergers an aggregate fee of $7 million, of which a portion was payable upon delivery of BofA Merrill Lynch's opinion and $6 million is contingent upon consummation of the Mergers. BofA Merrill Lynch and certain of its affiliates also expect to participate in the financing for the Mergers, including acting as joint lead arranger in connection with a debt refinancing, for which services BofA Merrill Lynch and its affiliates will receive an aggregate fee currently estimated to be approximately $3 million. US Ecology also has agreed to reimburse BofA Merrill Lynch for its expenses

incurred in connection with BofA Merrill Lynch's engagement and to indemnify BofA Merrill Lynch, any controlling person of BofA Merrill Lynch and each of their respective directors, officers, employees, agents and affiliates against specified liabilities, including liabilities under U.S. federal securities laws.

        BofA Merrill Lynch and its affiliates comprise a full service securities firm and commercial bank engaged in securities, commodities and derivatives trading, foreign exchange and other brokerage activities, and principal investing as well as providing investment, corporate and private banking, asset and investment management, financing and financial advisory services and other commercial services and products to a wide range of companies, governments and individuals. In the ordinary course of their businesses, BofA Merrill Lynch and its affiliates may invest on a principal basis or on behalf of customers or manage funds that invest, make or hold long or short positions, finance positions or trade or otherwise effect transactions in equity, debt or other securities or financial instruments (including derivatives, bank loans or other obligations) of US Ecology, Holdco, NRCG, JFLCo and/or certain of their respective affiliates and/or portfolio companies, as the case may be.

        BofA Merrill Lynch and its affiliates in the past have provided, currently are providing, and in the future may provide, investment banking, commercial banking and other financial services to US Ecology and have received or in the future may receive compensation for the rendering of these services, including having acted or acting as co-lead arranger and joint bookrunner for, and as a lender (including a letter of credit lender) to, US Ecology under its revolving credit facility. From June 1, 2017 through May 31, 2019, BofA Merrill Lynch and its affiliates derived aggregate revenues from US Ecology and/or certain of its affiliates of approximately $2 million for investment and corporate banking services. BofA Merrill Lynch and its affiliates did not provide investment and corporate banking services to NRCG from which BofA Merrill Lynch and its affiliates derived revenues from June 1, 2017 through May 31, 2019; during the same period, BofA Merrill Lynch and its affiliates derived aggregate revenues of less than $500,000 for investment and corporate banking services to JFLCo and/or certain of its portfolio companies.

Opinion of NRCG's Financial Advisor

        The NRCG Board retained Evercore to act as its financial advisor in connection with the Mergers. As part of this engagement, the NRCG Board requested that Evercore evaluate the fairness, from a financial point of view, of the NRCG Exchange Ratio of 0.1960 shares of Holdco Common Stock for each share of NRCG Common Stock to be received by the holders of shares of NRCG Common Stock. At a meeting of the NRCG Board held on June 23, 2019, Evercore rendered to the NRCG Board its opinion to the effect that, as of June 23, 2019 and based upon and subject to the assumptions, limitations, qualifications and conditions described in Evercore's opinion, the NRCG Exchange Ratio of 0.1960 shares of Holdco Common Stock for each share of NRCG Common Stock to be received by the holders of shares of NRCG Common Stock in the NRCG Merger was fair, from a financial point of view, to such holders.

        The full text of the written opinion of Evercore, dated June 23, 2019, which sets forth, among other things, the procedures followed, assumptions made, matters considered and qualifications and limitations on the scope of review undertaken in rendering its opinion, is attached as Annex I to this joint proxy statement/prospectus and is incorporated herein by reference. NRCG encourages you to read Evercore's opinion carefully and in its entirety. Evercore's opinion was addressed to, and provided for the information and benefit of, the NRCG Board (in its capacity as such) in connection with its evaluation of the proposed Mergers. The opinion does not constitute a recommendation to the NRCG Board or to any other persons in respect of the Mergers, including as to how any holder of shares of NRCG Common Stock should vote or act in respect of the Mergers. Evercore's opinion does not address the relative merits of the Mergers as compared to other business or financial strategies that

105


Table of Contents

might be available to NRCG, nor does it address the underlying business decision of NRCG to engage in the Mergers.

        In connection with rendering its opinion, Evercore, among other things:

        Set forth below is a summary of the material financial analyses reviewed by Evercore with the NRCG Board on June 23, 2019 in connection with rendering its opinion. The following summary, however, does not purport to be a complete description of the analyses performed by Evercore. The order of the analyses described and the results of these analyses do not represent relative importance or weight given to these analyses by Evercore. Except as otherwise noted, the following quantitative information, to the extent that it is based on market data, is based on market data that existed on or before June 21, 2019 (the last full trading date prior to the rendering of Evercore's opinion), and is not necessarily indicative of current market conditions.

        For purposes of its analyses and reviews, Evercore considered general business, economic, market and financial conditions, industry sector performance, and other matters, as they existed and could be evaluated as of the date of its opinion, many of which are beyond the control of NRCG. The estimates contained in Evercore's analyses and reviews, and the ranges of valuations resulting from any particular analysis or review, are not necessarily indicative of actual values or predictive of future results or values, which may be significantly more or less favorable than those suggested by Evercore's analyses

and reviews. In addition, analyses and reviews relating to the value of companies, businesses or securities do not purport to be appraisals or to reflect the prices at which companies, businesses or securities actually may be sold. Accordingly, the estimates used in, and the results derived from, Evercore's analyses and reviews are inherently subject to substantial uncertainty.

        The following summary of Evercore's financial analyses includes information presented in tabular format. In order to fully understand the analyses, the tables should be read together with the full text of each summary. The tables are not intended to stand alone and alone do not constitute a complete description of Evercore's financial analyses. Considering the tables below without considering the full narrative description of Evercore's financial analyses, including the methodologies and assumptions underlying such analyses, could create a misleading or incomplete view of such analyses.

Summary of Evercore's Financial Analyses

Discounted Cash Flow Analysis

NRCG

        Evercore performed a discounted cash flow analysis of NRCG under a perpetuity growth rate methodology and an EBITDA multiple methodology, to calculate the estimated present value of the standalone, unlevered, after-tax free cash flows, defined as net operating profit after tax, plus depreciation and amortization, less changes in net working capital and capital expenditures, that NRCG was forecasted to generate during NRCG's second quarter to fourth quarter 2019 and during fiscal years 2020 through 2023, based on the NRCG forecasts.

        Perpetuity Growth Rate Methodology.    Using the perpetuity growth rate methodology, Evercore calculated terminal values for NRCG by applying perpetuity growth rates of 2.0% to 3.0%, which range was selected based on Evercore's professional judgment and experience, to a terminal year estimate of the unlevered, after-tax free cash flows that NRCG was forecasted to generate based on the NRCG forecasts. The cash flows and terminal values in each case were then discounted to present value as of March 31, 2019 using discount rates ranging from 9.0% to 10.0%, which were based on an estimate of NRCG's weighted average cost of capital and the mid-year cash flow discounting convention. In calculating implied enterprise values, Evercore included the present value of tax savings from NRCG's estimated usage of net operating losses. Based on this range of implied enterprise values, NRCG's estimated net debt (calculated as total debt less cash and cash equivalents) as of March 31, 2019, and the number of fully diluted shares of NRCG Common Stock, in each case as provided by NRCG's management, this analysis indicated a range of implied equity values per share of NRCG Common Stock of $12.84 to $16.91.

        EBITDA Multiple Methodology.    Using the EBITDA multiple methodology, Evercore calculated terminal values for NRCG by applying terminal multiples of 8.00x to 10.00x, which range was selected based on Evercore's professional judgment and experience, to NRCG's Adjusted EBITDA in fiscal year 2023 based on the NRCG forecasts. The cash flows and terminal values in each case were then discounted to present value as of March 31, 2019 using discount rates ranging from 9.0% to 10.0%, which were based on an estimate of NRCG's weighted average cost of capital, and the mid-year cash flow discounting convention. In calculating implied enterprise values, Evercore included the present value of tax savings from NRCG's estimated usage of net operating losses. Based on this range of implied enterprise values, NRCG's estimated net debt (calculated as total debt less cash and cash equivalents) as of March 31, 2019, and the number of fully diluted shares of NRCG Common Stock, in each case as provided by NRCG's management, this analysis indicated a range of implied equity values per share of NRCG Common Stock of $15.35 to $19.83.

US Ecology

        Evercore performed a discounted cash flow analysis of US Ecology under a perpetuity growth rate methodology and an EBITDA multiple methodology to calculate the estimated present value of the standalone, unlevered, after-tax free cash flows, defined as net operating profit after tax, plus depreciation and amortization, less changes in net working capital and capital expenditures, that US Ecology was forecasted to generate during US Ecology's second quarter to fourth quarter 2019 and during fiscal years 2020 through 2023 based on the US Ecology forecasts.

        Perpetuity Growth Rate Methodology.    Using the perpetuity growth rate methodology, Evercore calculated terminal values for US Ecology by applying perpetuity growth rates of 2.0% to 3.0%, which range was selected based on Evercore's professional judgment and experience, to a terminal year estimate of the unlevered, after-tax free cash flows that US Ecology was forecasted to generate based on the US Ecology forecasts. The cash flows and terminal values in each case were then discounted to present value as of March 31, 2019 using discount rates ranging from 8.0% to 9.0%, which were based on an estimate of US Ecology's weighted average cost of capital and the mid-year cash flow discounting convention. Based on this range of implied enterprise values, US Ecology's estimated net debt (calculated as total debt less cash and cash equivalents) as of March 31, 2019, and the number of fully diluted shares of ECOL Common Stock, in each case as provided by US Ecology's management and approved for Evercore's use by NRCG, this analysis indicated a range of implied equity values per share of ECOL Common Stock of $53.63 to $78.00.

        EBITDA Multiple Methodology.    Using the EBITDA multiple methodology, Evercore calculated terminal values for US Ecology by applying terminal multiples of 9.0x to 12.0x, which range was selected based on Evercore's professional judgment and experience, to US Ecology's estimated Adjusted EBITDA in fiscal year 2023 based on the US Ecology forecasts. The cash flows and terminal values in each case were then discounted to present value as of March 31, 2019 using discount rates ranging from 8.0% to 9.0%, which were based on an estimate of US Ecology's weighted average cost of capital and the mid-year cash flow discounting convention. Based on this range of implied enterprise values, US Ecology's estimated net debt (calculated as total debt less cash and cash equivalents) as of March 31, 2019, and the number of fully diluted shares of ECOL Common Stock, in each case as provided by US Ecology's management and approved for Evercore's use by NRCG, this analysis indicated a range of implied equity values per share of ECOL Common Stock of $70.22 to $97.17.

Implied Relative Equity Value per Share

        Evercore calculated an implied exchange ratio reference range by dividing the low end of each implied share price reference range for NRCG by the high end of each implied share price reference range for US Ecology indicated by the discounted cash flow analyses and by dividing the high end of each implied share price reference range for NRCG by the low end of each implied share price reference range for US Ecology indicated by the discounted cash flow analyses. This analysis indicated an implied exchange ratio reference range of 0.1646 to 0.3152 shares of Holdco Common Stock for each share of NRCG Common Stock when applied to the implied share price reference ranges calculated using the perpetuity growth methodology, and indicated an implied exchange ratio reference range of 0.1580 to 0.2824 shares of Holdco Common Stock for each share of NRCG Common Stock when applied to the implied share price reference ranges calculated using the EBITDA multiple methodology, in each case as compared to the NRCG Exchange Ratio of 0.1960 shares of Holdco Common Stock for each share of NRCG Common Stock.

Selected Public Company Trading Analysis

        Evercore reviewed and compared certain financial information of NRCG and US Ecology to corresponding financial multiples and ratios for the following selected publicly traded companies in the environmental services and waste industries (the "selected companies"):

        For each of the selected companies, Evercore calculated (i) enterprise value (defined as equity market capitalization plus total debt, plus preferred equity and minority interest, less cash and cash equivalents) as a multiple of estimated 2019 EBITDA ("2019E EBITDA") based on closing share prices as of June 21, 2019 ("Price"), (ii) Price as a multiple of estimated 2019 earnings per share ("2019E EPS") and (iii) Price as a multiple of estimated 2019 earnings per share, on a normalized tax adjusted basis of 27.0% ("2019E Tax Adjusted EPS"). Estimated financial data of the selected companies (other than NRCG and US Ecology, which were based on the Forecasts), were based on publicly available research analysts' estimates.

        This analysis indicated the following:

Benchmark
  High   Low   Mean   Median  

2019E Adjusted EBITDA

    16.9x     7.3x     11.6x     11.2x  

Price/2019E EPS

    38.8x     14.2x     26.5x     26.9x  

Price/2019E Tax Adjusted EPS

    41.6x     15.6x     28.6x     28.0x  

NRCG

        2019E Adjusted EBITDA.    Based on the multiples it derived for the selected companies and based on its professional judgment and experience, Evercore applied an enterprise value/2019E EBITDA multiple reference range of 7.50x to 11.50x to NRCG's estimated 2019E Adjusted EBITDA based on the NRCG forecasts. In calculating implied enterprise values, Evercore included the present value of tax savings from NRCG's estimated usage of net operating losses. Based on this range of implied enterprise values, and NRCG's estimated net debt (calculated as total debt less cash and cash equivalents) as of March 31, 2019 and the number of fully diluted shares of NRCG Common Stock, in each case as provided by NRCG's management, this analysis indicated a range of implied equity values per share of NRCG Common Stock of $9.78 to $17.06.

        2019E EPS.    Based on the multiples it derived for the selected companies and based on its professional judgment and experience, Evercore applied a Price/2019E EPS multiple reference range of 20.00x to 25.00x to NRCG's estimated 2019E EPS based on the NRCG forecasts. Based on this range of implied equity values and the number of fully diluted shares of NRCG Common Stock, as provided

Table of Contents

by NRCG's management, this analysis indicated a range of implied equity values per share of NRCG Common Stock of $9.91 to $11.96.

        2019E Normalized Tax Adjusted EPS.    Based on the multiples it derived for the selected companies and based on its professional judgment and experience, Evercore applied a Price/2019E Normalized Tax Adjusted EPS multiple reference range of 23.50x to 28.00x to NRCG's estimated 2019E Normalized Tax Adjusted EPS based on the NRCG forecasts. In calculating implied equity values, Evercore included the present value of tax savings from NRCG's estimated usage of net operating losses. Based on this range of implied equity values and the number of fully diluted shares of NRCG Common Stock, as provided by NRCG's management, this analysis indicated a range of implied equity values per share of NRCG Common Stock of $9.20 to $10.87.

US Ecology

        2019E Adjusted EBITDA.    Based on the multiples it derived for the selected companies and based on its professional judgment and experience, Evercore applied an enterprise value/2019E EBITDA multiple reference range of 10.0x to 12.0x to US Ecology's estimated 2019E Adjusted EBITDA based on the US Ecology forecasts. Based on this range of implied enterprise values, and US Ecology's estimated net debt (calculated as total debt less cash and cash equivalents) as of March 31, 2019 and the number of fully diluted shares of ECOL Common Stock, in each case as provided by US Ecology's management and approved for Evercore's use by NRCG, this analysis indicated a range of implied equity values per share of ECOL Common Stock of $51.89 to $64.99.

        2019E EPS.    Based on the multiples it derived for the selected companies and based on its professional judgment and experience, Evercore applied a Price/2019E EPS multiple reference range of 23.0x to 27.0x to US Ecology's estimated 2019E EPS based on the US Ecology forecasts. Based on this range of implied equity values, and the number of fully diluted shares of ECOL Common Stock, as provided by US Ecology's management and approved for Evercore's use by NRCG management, this analysis indicated a range of implied equity values per share of ECOL Common Stock of $55.83 to $65.54.

        2019E Normalized Tax Adjusted EPS.    Based on the multiples it derived for the selected companies and based on its professional judgment and experience, Evercore applied a Price/2019E Normalized Tax Adjusted EPS multiple reference range of 23.5x to 28.0x to US Ecology's estimated Normalized Tax Adjusted EPS based on the US Ecology forecasts. Based on this range of implied equity values and the number of fully diluted shares of ECOL Common Stock, as provided by US Ecology's management and approved for Evercore's use by NRCG, this analysis indicated a range of implied equity values per share of ECOL Common Stock of $57.04 to $67.97.

Implied Relative Equity Value per Share

        Evercore calculated an implied exchange ratio reference range by dividing the low end of each implied share price reference range for NRCG by the high end of each implied share price reference range for US Ecology indicated by the trading multiples analyses and by dividing the high end of each implied share price reference range for NRCG by the low end of each implied share price reference range for US Ecology indicated by the trading multiples analyses. This analysis indicated (i) an implied exchange ratio reference range of 0.1505 to 0.3288 shares of Holdco Common Stock for each share of NRCG Common Stock when applied to the implied share price reference ranges calculated using the enterprise value/2019E EBITDA multiple, (ii) an implied exchange ratio reference range of 0.1513 to 0.2142 shares of Holdco Common Stock for each share of NRCG Common Stock when applied to the implied share price reference ranges calculated using the Price/2019E EPS multiple, and (iii) an implied exchange ratio reference range of 0.1353 to 0.1905 shares of Holdco Common Stock for each share of NRCG Common Stock when applied to the implied share price reference ranges calculated using the

Price/2019E Tax Adjusted EPS multiple, in each case as compared to the NRCG Exchange Ratio of 0.1960 shares of Holdco Common Stock for each share of NRCG Common Stock.

        Although none of the selected companies is directly comparable to NRCG, Evercore selected these companies because they are publicly traded in the environmental services and/or waste companies that Evercore, in its professional judgment and experience, considered generally relevant to NRCG for purposes of its financial analyses. In evaluating the selected companies, Evercore made judgments and assumptions with regard to general business, economic and market conditions affecting the selected companies and other matters, as well as differences in the selected companies' financial, business and operating characteristics. Accordingly, an evaluation of the results of this analysis is not entirely mathematical. Rather, this analysis involves complex considerations and judgments regarding many factors that could affect the relative values of the selected companies and the multiples derived from the selected companies. Mathematical analysis, such as determining the mean or median, is not in itself a meaningful method of using the data of the selected companies.

        For each selected transaction, Evercore calculated the implied enterprise value (defined as the target company's implied equity value based on the consideration paid in the applicable transaction plus total debt, plus preferred equity and minority interest, less cash and cash equivalents) as a multiple of last twelve-month EBITDA for the target company at the time of the announcement of the applicable transaction ("LTM EBITDA"). Estimated financial data of the selected transactions were based on publicly available information at the time of announcement of the relevant transaction.

        This analysis indicated the following:

Benchmark
  High   Low   Mean   Median  

LTM EBITDA—Environmental and Facilities Services

    19.7x     6.6x     11.3x     10.2x  

LTM EBITDA—Sanitation Services

    11.5x     7.1x     9.0x     8.8x  

        Based on the multiples it derived from the selected transactions and based on its professional judgment and experience, Evercore selected a reference range of enterprise value to LTM EBITDA multiples of 8.0x to 12.0x and applied this range of multiples to NRCG's LTM EBITDA as of March 31, 2019 based on the financial results for NRCG provided by NRCG's management. Based on this range of implied enterprise values, NRCG's estimated net debt (calculated as total debt less cash and cash equivalents) as of March 31, 2019, and the number of fully diluted shares of NRCG Common Stock, in each case as provided by NRCG's management, this analysis indicated a range of implied equity values per share of NRCG Common Stock of $7.48 to $14.60.

Implied Relative Equity Value per Share

        Evercore calculated an implied exchange ratio reference range by dividing each of the low end and the high end of the implied share price reference range for NRCG indicated by the selected transactions analysis by $62.74, which reflects the closing share price of ECOL Common Stock as of June 21, 2019. This analysis indicated an implied exchange ratio reference range of 0.1193 to 0.2327 shares of Holdco Common Stock for each share of NRCG Common Stock, as compared to the NRCG Exchange Ratio of 0.1960 shares of Holdco Common Stock for each share of NRCG Common Stock.

        Although none of the target companies or businesses reviewed in the selected transactions analysis is directly comparable to NRCG and none of the selected transactions is directly comparable to the Mergers, Evercore selected these transactions because they involve companies or businesses that Evercore, in its professional judgment and experience, considered generally relevant to NRCG for purposes of its financial analyses. In evaluating the selected transactions, Evercore made judgments and assumptions with regard to general business, economic and market conditions and other factors existing at the time of the selected transactions, and other matters, as well as differences in financial, business and operating characteristics and other factors relevant to the target companies or businesses in the selected transactions. Accordingly, an evaluation of the results of this analysis is not entirely mathematical. Rather, this analysis involves complex considerations and judgments regarding many factors that could affect the relative values of the target companies or businesses in the selected transactions and the multiples derived from the selected transactions. Mathematical analysis, such as determining the mean or median, is not in itself a meaningful method of using the data of the selected transactions.

Other Factors

        Evercore also noted certain other factors, which were not considered material to its financial analyses with respect to its opinion, but were referenced for informational purposes only, including, among other things, the following:

        Using publicly available information, Evercore reviewed 64 all-stock transactions and announced bids for control of U.S. public targets with an aggregate transaction value between $500 million and $1.5 billion announced since January 1, 2010. Using publicly available information, Evercore calculated the premiums paid as the percentage by which the per share consideration paid or proposed to be paid in each such transaction exceeded the closing market prices per share of the target companies one day, one week and one month prior to announcement of each transaction.

        This analysis indicated the following:

        Based on the results of this analysis and its professional judgment and experience, Evercore applied a premium range of 20.0% to 40.0% to the closing price per share of NRCG Common Stock of $8.83 as of June 21, 2019. This analysis indicated a range of implied equity values per share of NRCG Common Stock of $10.60 to $12.36.

Implied Relative Equity Value per Share

        Evercore calculated an implied exchange ratio reference range by dividing each of the low end and the high end of the implied share price reference range for NRCG indicated by the premiums paid analysis by $62.74, which reflects the closing share price of ECOL Common Stock as of June 21, 2019. This analysis indicated an implied exchange ratio reference range of 0.1689 to 0.1970 shares of Holdco Common Stock for each share of NRCG Common Stock, as compared to the NRCG Exchange Ratio of 0.1960 shares of Holdco Common Stock for each share of NRCG Common Stock.

Equity Research Analyst Price Targets

NRCG

        Evercore reviewed selected public market trading price targets for the shares of NRCG Common Stock prepared and published by equity research analysts that were publicly available as of June 21, 2019, the last full trading day prior to the delivery by Evercore of its opinion to the NRCG Board. These price targets reflect analysts' estimates of the future public market trading price of the shares of NRCG Common Stock at the time the price target was published. As of June 21, 2019, the range of selected equity research analyst price targets per share of NRCG Common Stock was $12.00 to $15.00. Public market trading price targets published by equity research analysts do not necessarily reflect current market trading prices for the shares of NRCG Common Stock and these target prices and the analysts' earnings estimates on which they were based are subject to risk and uncertainties, including factors affecting the financial performance of NRCG and future general industry and market conditions.

US Ecology

        Evercore reviewed selected public market trading price targets for the shares of ECOL Common Stock prepared and published by equity research analysts that were publicly available as of June 21, 2019, the last full trading day prior to the delivery by Evercore of its opinion to the NRCG Board. These price targets reflect analysts' estimates of the future public market trading price of the shares of ECOL Common Stock at the time the price target was published. As of June 21, 2019, the range of selected equity research analyst price targets per share of ECOL Common Stock was $59.00 to $72.00. Public market trading price targets published by equity research analysts do not necessarily reflect current market trading prices for the shares of ECOL Common Stock and these target prices and the analysts' earnings estimates on which they were based are subject to risk and uncertainties, including factors affecting the financial performance of US Ecology and future general industry and market conditions.

Implied Relative Equity Value per Share

        Evercore calculated an implied exchange ratio reference range by dividing the low end of the implied share price reference range for NRCG by the high end of the implied share price reference range for US Ecology indicated by the analyst price targets analysis and by dividing the high end of the implied share price reference range for NRCG by the low end of the implied share price reference range for US Ecology indicated by the analyst price targets analysis. This analysis indicated an implied exchange ratio reference range of 0.1667 to 0.2542 shares of Holdco Common Stock for each share of NRCG Common Stock, as compared to the NRCG Exchange Ratio of 0.1960 shares of Holdco Common Stock for each share of NRCG Common Stock.

Last 52-Week Trading Range

NRCG

        Evercore reviewed historical trading prices of shares of NRCG Common Stock during the twelve month period ended June 21, 2019, noting that the low and high closing prices during such period ranged from $6.65 to $10.26 per share of NRCG Common Stock, respectively.

US Ecology

        Evercore reviewed historical trading prices of shares of ECOL Common Stock during the twelve month period ended June 21, 2019, noting that the low and high closing prices during such period ranged from $54.63 to $76.55 per share of ECOL Common Stock, respectively.

Implied Relative Equity Value per Share

        Evercore calculated an implied exchange ratio reference range by dividing the low end of the implied share price reference range for NRCG by the high end of the implied share price reference range for US Ecology indicated by the 52-week trading range analysis and by dividing the high end of the implied share price reference range for NRCG by the low end of each implied share price reference range for US Ecology indicated by the 52-week trading range analysis. This analysis indicated an implied exchange ratio reference range of 0.0869 to 0.1878 shares of Holdco Common Stock for each share of NRCG Common Stock, as compared to the NRCG Exchange Ratio of 0.1960 shares of Holdco Common Stock for each share of NRCG Common Stock.

Historical Share Price Ratio

        Evercore reviewed the historical share price ratio of shares of NRCG Common Stock to shares of ECOL Common Stock since October 17, 2018, by dividing the closing price for shares of NRCG Common Stock by the closing price for shares of ECOL Common Stock as of the end of each trading day during this period. This indicated a three-year ratio reference range of 0.0969 to 0.1717 shares of Holdco Common Stock for each share of NRCG Common Stock, as compared to the NRCG Exchange Ratio of 0.1960 shares of Holdco Common Stock for each share of NRCG Common Stock.

Miscellaneous

        The foregoing summary of Evercore's financial analyses does not purport to be a complete description of the analyses or data presented by Evercore to the NRCG Board. In connection with the review of the Mergers by the NRCG Board, Evercore performed a variety of financial and comparative analyses for purposes of rendering its opinion. The preparation of a fairness opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. Selecting portions of the analyses or of the summary described above, without considering the analyses as a whole, could create an incomplete view of the processes underlying Evercore's opinion. In arriving at its fairness determination, Evercore considered the results of all the analyses and did not draw, in isolation, conclusions from or with regard to any one analysis or factor considered by it for purposes of its opinion. Rather, Evercore made its determination as to fairness on the basis of its professional judgment and experience after considering the results of all the analyses. In addition, Evercore may have given various analyses and factors more or less weight than other analyses and factors, and may have deemed various assumptions more or less probable than other assumptions. As a result, the ranges of valuations resulting from any particular analysis or combination of analyses described above should not be taken to be the view of Evercore with respect to the actual value of the shares of NRCG Common Stock. Rounding may result in total sums set forth in this section not equaling the total of the figures shown.

        Evercore prepared these analyses for the purpose of providing an opinion to the NRCG Board as to the fairness, from a financial point of view, of the NRCG Exchange Ratio of 0.1960 shares of Holdco Common Stock for each share of NRCG Common Stock to be received by holders of shares of NRCG Common Stock in the NRCG Merger. These analyses do not purport to be appraisals or to necessarily reflect the prices at which the business or securities actually may be sold. Any estimates contained in these analyses are not necessarily indicative of actual future results, which may be significantly more or less favorable than those suggested by such estimates. Accordingly, estimates used in, and the results derived from, Evercore's analyses are inherently subject to substantial uncertainty, and Evercore assumes no responsibility if future results are materially different from those forecasted in such estimates.

Table of Contents

        Evercore's financial advisory services and its opinion were provided for the information and benefit of the NRCG Board (in its capacity as such) in connection with its evaluation of the proposed Mergers. The issuance of Evercore's opinion was approved by an Opinion Committee of Evercore.

        Evercore did not recommend any specific amount of consideration to the NRCG Board or NRCG's management or that any specific amount of consideration constituted the only appropriate consideration in the NRCG Merger for the holders of NRCG Common Stock.

        Pursuant to the terms of Evercore's engagement letter with NRCG, NRCG has agreed to pay Evercore a fee for its services in the amount of approximately $3 million, of which $1 million was paid upon delivery of Evercore's opinion, and the balance of which will be payable contingent upon the consummation of the Mergers. NRCG has also agreed to reimburse Evercore for its expenses and to indemnify Evercore against certain liabilities arising out of its engagement.

        During the two-year period prior to the date of its opinion, Evercore and its affiliates have not been engaged to provide financial advisory or other services to NRCG, and Evercore has not received any compensation from NRCG during such period. In addition, during the two-year period prior to the date of its opinion, Evercore and its affiliates have not been engaged to provide financial advisory or other services to US Ecology, and Evercore has not received any compensation from US Ecology during such period. Evercore may provide financial advisory or other services to NRCG, US Ecology and Holdco in the future, and in connection with any such services Evercore may receive compensation.

        Evercore and its affiliates engage in a wide range of activities for its and their own accounts and the accounts of customers, including corporate finance, mergers and acquisitions, equity sales, trading and research, private equity, placement agent, asset management and related activities. In connection with these businesses or otherwise, Evercore and its affiliates and/or its or their respective employees, as well as investment funds in which any of them may have a financial interest, may at any time, directly or indirectly, hold long or short positions and may trade or otherwise effect transactions for their own accounts or the accounts of customers, in debt or equity securities, senior loans and/or derivative products or other financial instruments of or relating to NRCG or its affiliates, US Ecology, Holdco, potential parties to the Mergers and/or any of their respective affiliates or persons that are competitors, customers or suppliers of NRCG, US Ecology or Holdco.

        NRCG engaged Evercore to act as a financial advisor based on Evercore's qualifications, experience and reputation. Evercore is an internationally recognized investment banking firm and regularly provides fairness opinions to its clients in connection with mergers and acquisitions, leveraged buyouts and valuations for corporate and other purposes.

Certain Financial Forecasts Prepared by US Ecology Management

        US Ecology does not, as a matter of course, publicly disclose forecasts or projections as to future performance, earnings or other results, other than previously disclosed guidance for fiscal year 2019, given the inherent difficulty of predicting financial performance for future periods and the possibility that the underlying assumptions and estimates may prove not to be appropriate. However, in the course of evaluating the Mergers and negotiating the Merger Agreement, US Ecology management shared with NRCG and made available to the US Ecology Board certain unaudited financial projections and estimates of future financial and operating performance for US Ecology for fiscal years 2019 through 2023 (1) assuming organic growth but excluding growth from potential mergers and acquisitions activities (the "US Ecology Organic Growth Projections") and (2) assuming organic growth and potential growth from potential mergers and acquisitions activities, not including the Mergers (the "US Ecology Projections Including Inorganic Growth" and, together with the US Ecology Organic Growth Projections, the "US Ecology Unaudited Financial Projections"). The US Ecology Unaudited

116


Table of Contents

Financial Projections were prepared in May 2019 in connection with US Ecology's evaluation of a potential strategic transaction with NRCG.

        In addition, US Ecology management used the portion of the NRCG Unaudited Financial Projections (as defined below) shared with US Ecology by NRCG's management to prepare certain unaudited financial projections and estimates of future financial and operating performance of NRCG for fiscal years 2019 through 2023 (the "US Ecology-Prepared NRCG Unaudited Financial Projections"). The US Ecology-Prepared NRCG Unaudited Financial Projections were prepared in May and June 2019 in connection with the US Ecology's evaluation of a potential strategic transaction with NRCG.

        The US Ecology Unaudited Financial Projections and the US Ecology-Prepared NRCG Unaudited Financial Projections were reviewed by the US Ecology Board in connection with its review and evaluation of the Mergers, and also were provided to BofA Merrill Lynch, which was instructed by US Ecology to use and rely upon the US Ecology Organic Growth Projections and the US Ecology-Prepared NRCG Unaudited Financial Projections for purposes of its financial analyses and opinion to the US Ecology Board, as described in the section entitled "The Mergers—Opinion of US Ecology's Financial Advisor." The US Ecology Unaudited Financial Projections also were provided to NRCG in connection with its evaluation of the Mergers, and also were provided to NRCG's financial advisor, Evercore, in connection with the proposed Mergers.

        The US Ecology Unaudited Financial Projections and the US Ecology-Prepared NRCG Unaudited Financial Projections were prepared by US Ecology management on a standalone basis without giving effect to the transactions contemplated by the Merger Agreement, and therefore the US Ecology Unaudited Financial Projections and the US Ecology-Prepared NRCG Unaudited Financial Projections do not give effect to the Mergers and the other transactions contemplated by the Merger Agreement or any changes to US Ecology's or NRCG's, as applicable, operations or strategy that may be implemented after the consummation of the Mergers, including any costs incurred in connection with the Mergers and the other transactions contemplated by the Merger Agreement. Furthermore, the US Ecology Unaudited Financial Projections and the US Ecology-Prepared NRCG Unaudited Financial Projections do not take into account the effect of a failure of the transactions contemplated by the Merger Agreement to be completed and should not be viewed in that context.

        Neither the US Ecology Unaudited Financial Projections nor the US Ecology-Prepared NRCG Unaudited Financial Projections summarized below were prepared for purposes of public disclosure, nor were they prepared on a basis designed to comply with the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of "prospective financial information," or GAAP. US Ecology's independent auditor, which is listed as an expert below in the section entitled "Experts," did not compile, examine, or perform any procedures with respect to the US Ecology Unaudited Financial Projections or the US Ecology-Prepared NRCG Unaudited Financial Projections, and has not expressed any opinion or any other form of assurance on such information or its achievability, and assumes no responsibility for, and disclaims any association with, such projections.

        Although presented with numerical specificity, the US Ecology Unaudited Financial Projections and the US Ecology-Prepared NRCG Unaudited Financial Projections were prepared in the context of numerous variables, estimates, and assumptions that are inherently uncertain and may be beyond the control of US Ecology, and which may prove not to have been, or to no longer be, appropriate. Although considered reasonable by US Ecology's management as of the date of their preparation, the US Ecology Unaudited Financial Projections and the US Ecology-Prepared NRCG Unaudited Financial Projections are subject to many risks and uncertainties. Important factors that may affect actual results

and cause actual results to differ materially from these projections include, but are not limited to, risks and uncertainties relating to US Ecology's or NRCG's, as applicable, business (including such company's ability to achieve strategic goals, objectives, and targets over the applicable periods), industry performance, the regulatory environment, general business and economic conditions, market and financial conditions, and various risks set forth in US Ecology's reports filed with the SEC with respect to the US Ecology Unaudited Financial Projections and in NRCG's reports filed with the SEC with respect to the US Ecology-Prepared NRCG Unaudited Financial Projections, and other factors described or referenced under the sections entitled "Risk Factors" and "Cautionary Statement Regarding Forward-Looking Statements" of this joint proxy statement/prospectus.

        The US Ecology Unaudited Financial Projections and the NRCG-Prepared US Ecology Unaudited Financial Projections (as defined below) also reflect assumptions that are subject to change and are susceptible to multiple interpretations and periodic revisions based on actual results, revised prospects for US Ecology's or NRCG's business, as applicable, changes in general business or economic conditions, or any other transaction or event that has occurred or that may occur and that was not anticipated at the time the US Ecology Unaudited Financial Projections or the US Ecology-Prepared NRCG Unaudited Financial Projections were prepared. Further, the US Ecology Unaudited Financial Projections and the US Ecology-Prepared NRCG Unaudited Financial Projections do not take into account any circumstances, transactions, or events occurring after the date they were prepared. Accordingly, actual results will likely differ, and may differ materially, from those contained in the US Ecology Unaudited Financial Projections and the US Ecology-Prepared NRCG Unaudited Financial Projections. There can be no assurance that these financial projections will be realized or that future financial results of US Ecology (or, following consummation of the Mergers, the combined company) or NRCG, as applicable, will not materially vary from these financial projections.

Readers are cautioned not to place undue reliance on the US Ecology Unaudited Financial Projections or the US Ecology-Prepared NRCG Unaudited Financial Projections.

        The US Ecology Unaudited Financial Projections and the US Ecology-Prepared NRCG Unaudited Financial Projections include certain non-GAAP financial measures, including Adjusted EBITDA and Unlevered Free Cash Flow. Non-GAAP financial measures should not be considered in isolation from, or a substitute for, financial information presented in compliance with GAAP, and non-GAAP financial measures as used by US Ecology management in preparing the US Ecology Unaudited Financial Projections and the US Ecology-Prepared NRCG Unaudited Financial Projections may not be comparable to similarly titled amounts used by other companies.

Certain Financial Forecasts Prepared by NRCG Management

        NRCG does not, as a matter of course, publicly disclose forecasts or projections as to future performance, earnings or other results, other than previously disclosed guidance for fiscal year 2019, given the inherent difficulty of predicting financial performance for future periods and the possibility that the underlying assumptions and estimates may prove not to be appropriate. However, in the course of evaluating the Mergers and negotiating the Merger Agreement, NRCG management made available to the NRCG Board certain unaudited financial projections and estimates of future financial and operating performance for NRCG for fiscal years 2019 through 2023 (the "NRCG Unaudited Financial Projections"). The NRCG Unaudited Financial Projections were initially prepared in February 2019 in connection with certain financing-related activities.

        In addition, NRCG management used the US Ecology Projections Including Inorganic Growth shared with NRCG by US Ecology's management to prepare certain unaudited financial projections and estimates of future financial and operating performance of US Ecology for the last three quarters of fiscal year 2019 through fiscal year 2023 (the "NRCG-Prepared US Ecology Unaudited Financial Projections"). The NRCG-Prepared US Ecology Unaudited Financial Projections were prepared in May 2019 in connection with NRCG's evaluation of a potential strategic transaction with US Ecology.

        The NRCG Unaudited Financial Projections and the NRCG-Prepared US Ecology Unaudited Financial Projections were reviewed by the NRCG Board in connection with its review and evaluation of the Mergers, and also were provided to Evercore, which relied upon the NRCG Unaudited Financial Projections, the NRCG-Prepared US Ecology Unaudited Financial Projections and the US Ecology Projections Including Inorganic Growth for purposes of its financial analyses and opinion to the NRCG Board, as described in the section entitled "The Mergers—Opinion of NRCG's Financial Advisor." The NRCG Unaudited Financial Projections for the fiscal years 2019 through 2022 were also provided to US Ecology in connection with its evaluation of the Mergers, and also were provided to US Ecology's financial advisor, BofA Merrill Lynch, in connection with the proposed Mergers.

        The NRCG Unaudited Financial Projections and the NRCG-Prepared US Ecology Unaudited Financial Projections were prepared by NRCG management on a standalone basis without giving effect to the transactions contemplated by the Merger Agreement, and therefore the NRCG Unaudited Financial Projections and the NRCG-Prepared US Ecology Unaudited Financial Projections do not give effect to the Mergers and the other transactions contemplated by the Merger Agreement or any changes to NRCG's or US Ecology's, as applicable, operations or strategy that may be implemented after the consummation of the Mergers, including any costs incurred in connection with the Mergers and the other transactions contemplated by the Merger Agreement. Furthermore, the NRCG Unaudited Financial Projections do not take into account the effect of a failure of the transactions contemplated by the Merger Agreement to be completed and should not be viewed in that context.

        Neither the NRCG Unaudited Financial Projections nor the NRCG-Prepared US Ecology Unaudited Financial Projections summarized below were prepared for purposes of public disclosure, nor were they prepared on a basis designed to comply with the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of "prospective financial information," or GAAP. NRCG's independent auditors, which are listed as experts below in the section entitled "Experts," did not audit, review, examine, compile, or apply agreed-upon procedures with respect to the NRCG Unaudited Financial Projections or the NRCG-Prepared US Ecology Unaudited Financial Projections, and have not expressed any opinion or any other form of assurance on such information or its achievability, and assume no responsibility for, and disclaim any association with such projections.

Although considered reasonable by NRCG's management as of the date of their preparation, the NRCG Unaudited Financial Projections are subject to many risks and uncertainties. Important factors that may affect actual results and cause actual results to differ materially from these projections include, but are not limited to, risks and uncertainties relating to NRCG's business (including its ability to achieve strategic goals, objectives, and targets over the applicable periods), industry performance, the regulatory environment, general business and economic conditions, market and financial conditions, and various risks set forth in NRCG's reports filed with the SEC with respect to NRCG and US Ecology's reports filed with the SEC with respect to the NRCG-Prepared US Ecology Unaudited Financial Projections, and other factors described or referenced in the sections entitled "Risk Factors" and "Cautionary Statement Regarding Forward-Looking Statements" of this joint proxy statement/prospectus.

Indebtedness Following the Mergers

        US Ecology is currently party to the Credit Agreement, dated as of April 18, 2017, by and among US Ecology, the lenders party thereto from time to time, Wells Fargo Bank, National Association, a national banking association, as administrative agent for the lenders, as swingline lender and as an issuing lender, and Bank of America, N.A., as an issuing lender (the "Existing Credit Agreement"). The Existing Credit Agreement provides for a $500 million revolving credit facility. US Ecology entered into the First Amendment, dated as of August 6, 2019, to amend the Existing Credit Facility to, among other things, permit a $400 million incremental term loan, and the First Amendment shall become effective upon the consummation of the Mergers. US Ecology is pursuing a Lender Joinder Agreement and Second Amendment which intends to amend the Credit Agreement to expand the capacity for incremental term loans by an additional $50 million and to incur a $450 million incremental term loan, which incremental term loan shall, together with borrowings under US Ecology's existing revolving credit facility, be used to refinance existing indebtedness of NRCG, to pay the fees and expenses incurred in connection with the Mergers and the transactions in connection therewith and to pay down a portion of the outstanding amount of the existing revolving credit facility.

Interests of US Ecology Directors and Executive Officers in the Mergers

        In considering the recommendation of the US Ecology Board with respect to the proposal to adopt the Merger Agreement, US Ecology stockholders should be aware that executive officers and directors of US Ecology may have certain interests in the Mergers that may be different from, or in addition to, the interests of US Ecology stockholders generally. In particular, the Holdco Board after the Mergers is expected to be identical of the US Ecology Board immediately prior to the Mergers. It is currently expected that the compensation to be paid to outside directors of Holdco will be identical

123


Table of Contents

to the compensation paid to US Ecology directors immediately prior to the Effective Time. In addition, the named executed officers of Holdco after the Mergers are expected to be the named executed officers of US Ecology immediately prior to the Mergers. It is currently expected that the compensation to be paid to the named executive officers of Holdco will be identical to the compensation paid to US Ecology named executive officers immediately prior to the Effective Time. See the section entitled "—Holdco Board, Management and Certain Governance Matters Following the Mergers." The US Ecology Board was aware of these potentially differing interests and considered them, among other matters, in reaching its decision to adopt the Merger Agreement and approve the Mergers and to recommend that US Ecology common stockholders vote in favor of the US Ecology Merger Agreement Proposal, the Holdco Stock Issuance Proposal and the Holdco Charter Amendment Proposal.

Interests of NRCG Directors and Executive Officers in the Mergers

        In considering the recommendation of the NRCG Board with respect to the proposal to adopt the Merger Agreement, NRCG common stockholders should be aware that NRCG's executive officers and directors may have interests in the Mergers that may be different from, or in addition to, the interests of NRCG common stockholders generally, including (1) the acceleration of vesting of NRCG's stock options, (2) the assumption of NRCG RSUs by Holdco, (3) potential severance payments and the vesting of equity awards in connection with a qualifying termination of employment and (4) ongoing indemnification and insurance obligations by Holdco, each as further summarized in the subsections below. The NRCG Board was aware of these potentially differing interests summarized below and considered them, among other matters, in reaching its decision to adopt the Merger Agreement and approve the Mergers and to recommend that NRCG common stockholders vote in favor of adopting the Merger Agreement.

        Set forth below are the descriptions of the interests of the NRCG directors and executive officers in the Mergers.

Consideration for NRCG Common Stock at the Effective Time of the Mergers

        At the Effective Time of the Mergers, the outstanding capital stock beneficially owned by the executive officers and directors of NRCG will be converted into the right to receive the same merger consideration on the same terms and conditions as the other NRCG stockholders.

NRCG Stock Options

        As of the Effective Time, each NRCG stock option that is outstanding as of immediately prior to the Effective Time, whether or not then vested or exercisable, shall be automatically assumed by Holdco and shall be converted into a fully vested and immediately exercisable option to acquire that number of whole shares of Holdco Common Stock equal to the product (rounded down to the nearest whole share) of (1) the number of shares of NRCG Common Stock subject to such NRCG stock option as of immediately prior to the Effective Time and (2) the NRCG Exchange Ratio, at an exercise price per share of Holdco Common Stock (rounded up to the nearest whole cent) equal to the quotient obtained by dividing (i) the exercise price per share of NRCG Common Stock of such NRCG stock option as of immediately prior to the Effective Time by (ii) the NRCG Exchange Ratio; provided, that the exercise price and the number of shares of Holdco Common Stock subject to such replacement option shall be determined in a manner consistent with the requirements of Section 409A of the Code. Each such replacement option shall have, and shall be subject to, substantially the same terms and conditions (other than vesting) as applied to the corresponding NRCG stock option immediately prior to the Effective Time, with such revisions as Holdco in its good faith discretion determines are necessary to reflect (1) the conversion of the applicable NRCG stock option into a replacement Holdco stock option, (2) the fact that such NRCG stock option is exercisable for shares of Holdco Common Stock and (3) the NRCG Merger. Based on the NRCG stock option holdings as of September 6, 2019,

the number and value of NRCG stock options held by each of NRCG's non-employee directors is set forth below. All such NRCG stock options have an exercise price of $10.25 per share and are unvested as of September 6, 2019 with the first vesting date to occur in accordance with its terms on October 17, 2019 if the Mergers have not been consummated by that time. None of NRCG's executive officers held NRCG stock options as of September 6, 2019.

NRCG Restricted Stock Units

        As of the Effective Time, each NRCG RSU that is outstanding as of immediately prior to the Effective Time shall be automatically assumed by Holdco and shall be converted into a RSU of Holdco covering that number of whole shares of Holdco Common Stock equal to the product (rounded to the nearest whole number) of (1) one and (2) the NRCG Exchange Ratio. Each such Holdco replacement RSU shall have, and be subject to, substantially the same terms and conditions that were applicable to the corresponding NRCG RSU immediately before the Effective Time, with such revisions as Holdco in its good faith discretion determines are necessary to reflect (1) the conversion of the applicable NRCG RSU into a Holdco replacement RSU and (2) the NRCG Merger. No NRCG RSU shall become vested solely by reason of the execution of the Merger Agreement or the consummation of the transactions contemplated by the Merger Agreement. Based on the NRCG RSU holdings as of September 6, 2019, the number and value of NRCG RSUs held by each of NRCG's executive officers is set forth below.

NRCG Employment Agreements

        Christian Swinbank entered into an employment agreement with NRC Group on July 18, 2018. Pursuant to this agreement, if (1) Mr. Swinbank's employment with NRCG ends on account of a Termination Without Cause or a Termination With Good Reason (each, as defined below), in each case, within 24 months following a change in control or (2) Mr. Swinbank's employment with NRCG ends on account of a Termination Without Cause within three months prior to a Change in Control,

125


Table of Contents

Mr. Swinbank will be entitled to receive severance compensation in an amount equal to 200% multiplied by the sum of his base salary plus his target annual bonus.

        Joseph Peterson entered into an employment agreement with NRC Group on June 22, 2018. Pursuant to this agreement, if (1) Mr. Peterson's employment with NRCG ends on account of a Termination Without Cause or a Termination With Good Reason, in each case, within 24 months following a change in control or (2) during the three-month period preceding a Change in Control, Mr. Peterson's employment with NRCG ends on account of a Termination Without Cause in anticipation of a Change in Control transaction that the NRCG Board is actively considering and that is ultimately consummated, Mr. Peterson will be entitled to receive severance compensation in an amount equal to 200% multiplied by the sum of his base salary plus his target annual bonus.

        Such severance compensation is payable to each of Messrs. Swinbank and Peterson in equal installments over the 24-month period immediately following the applicable executive's termination of employment and is contingent upon timely execution and non-revocation of a general release of claims in favor of NRCG. The NRCG Merger will be a "change in control" for purposes of each executive's employment agreement.

        Additionally, if either executive's employment with NRCG ends on account of a Termination Without Cause or a Termination With Good Reason at any time, he will be entitled to reimbursement for the full amount of his COBRA premium payments for up to eighteen months. The executives' employment agreements also include an obligation not to compete with NRCG or solicit NRCG's employees or customers, in each case, while employed by NRCG and for a period of eighteen months following their termination of employment. If any amounts payable to Messrs. Swinbank or Peterson pursuant to his employment agreement would be subject to an excise tax under Section 4999 of the Internal Revenue Code, then either (1) the payments will be reduced by the amount needed to avoid triggering such excise tax, or (2) there will be no reduction of the payments, depending on which alternative leaves the executive in the best after-tax position.

        For purposes of the executives' employment agreements described above, the following definitions apply:

Equity Acceleration Under Restricted Stock Unit Agreements

        Each of Messrs. Swinbank and Peterson is party to an RSU agreement with NRCG dated as of April 5, 2019. As described above in the section entitled "—NRCG Restricted Stock Units" of this joint proxy statement/prospectus, each of the executive's RSUs will be assumed by and converted into Holdco RSUs in connection with the Mergers. However, the RSU agreements provide that if, after receiving such a replacement award, the executive experiences a termination of employment with NRCG or a subsidiary or any of their successors as a result of a termination without Cause or a termination by the executive for Good Reason (each as defined below), in any case, that occurs within two years following the change in control and during the remaining vesting period for the replacement award, such replacement award will become fully vested and payable upon such termination of employment. The NRCG Merger will be a "change in control" for purposes of each executive's RSU agreement.

        For purposes of the executives' RSU agreements described above, the following definitions apply:

Litigation Related to the Mergers

        On July 23, 2019, SBTS, LLC ("SBTS") filed a complaint captioned SBTS, LLC vs. NRC Group Holdings Corp. et al. (Civil Action No. 2019-0566-JTL), in the Court of Chancery of the State of Delaware (the "Court of Chancery") against NRCG, NRC Group and US Ecology (the "Complaint"). In the Complaint, SBTS alleges that (1) the exchange (the "Preferred Exchange") of the NRCG Series A Preferred Stock pursuant to the Merger Agreement breaches certain provisions of the NRCG Series A Certificate of Designations, (2) the Preferred Exchange would violate Section 242 of the DGCL, (3) SBTS would suffer irreparable harm if NRCG and US Ecology are not enjoined from consummating the transactions contemplated by the Merger Agreement and (4) US Ecology had knowledge of the relevant sections of the NRCG Series A Certificate of Designations and still required the Merger Agreement to include the Preferred Exchange.

        In the Complaint, SBTS requests that the Court of Chancery (1) render a declaratory judgment that (a) the terms of the Merger Agreement violate certain provisions of the NRCG Series A Certificate of Designations, (b) the removal of the NRCG Series A Preferred Stock designee from the NRCG Board violates NRCG's Certificate of Incorporation and the NRCG Series A Certificate of Designations, and (c) the terms of the Merger Agreement violate Section 242 of the DGCL, (2) enjoin NRCG from convening a vote of its common stockholders to adopt the Merger Agreement, (3) enjoin NRCG and US Ecology from consummating the transactions contemplated by the Merger Agreement, (4) find US Ecology liable for tortious interference with a contract and award SBTS the damages caused by US Ecology's actions, (5) award SBTS costs and expenses in connection with the action and (6) grant SBTS any such further relief as justice and its cause may require. The parties filed cross motions for summary judgment and, on September 11, 2019, the Court of Chancery granted the motions for summary judgment filed by NRCG, NRC Group and US Ecology, thereby dismissing with prejudice all of the claims asserted by SBTS against NRCG, NRC Group and US Ecology.

        US Ecology and NRCG, as applicable, have agreed to promptly advise the other party of any litigation commenced, or to its knowledge threatened, after the date of the Merger Agreement against such party or any of their respective directors by any stockholder of such party (on their own behalf or on behalf of such party) relating to the Merger Agreement or the transactions contemplated by the Merger Agreement (including the Mergers), and to keep the other party reasonably informed regarding any such litigation. US Ecology and NRCG, as applicable, have agreed to give the other party the opportunity to consult with such party regarding the defense or settlement of any such stockholder litigation, to consider the other party's views with respect to such stockholder litigation, and that no such settlement will be agreed to without the other party's prior written consent (which consent must not be unreasonably withheld, conditioned or delayed).

Regulatory Clearances Required for the Mergers

        Under the HSR Act, US Ecology and NRCG must file notifications with the FTC and the Antitrust Division and observe a mandatory pre-merger waiting period before completing the Mergers. On July 8, 2019, each of US Ecology and JFL-AIV Investors III-JA, L.P. (on behalf of NRCG) filed its notification under the HSR Act. On July 16, 2019, each of US Ecology and JFL-AIV Investors III-JA, L.P. (as the controlling stockholder of NRCG) received early termination of the waiting period under the HSR Act. Accordingly, the condition to the Mergers related to obtaining that clearance has been satisfied.

129


Table of Contents

        US Ecology and NRCG cannot assure you that the FTC, the Antitrust Division or private parties will not initiate actions to challenge the Mergers before or after they are completed. Any such challenge to the Mergers could result in a court order enjoining the Mergers or in restrictions or conditions that would have a material adverse effect on the combined company if the Mergers are completed. Such restrictions and conditions could include requiring the divestiture or spin-off of assets or businesses. Under the terms of the Merger Agreement, each of US Ecology, and NRCG are required to use reasonable best efforts to expeditiously take, or cause to be taken, all actions, and to do, or cause to be done and to assist and cooperate with the other parties in doing, all things necessary, proper or advisable to consummate and make effective, and to satisfy all conditions to the transactions contemplated by the Merger Agreement. However, nothing in the Merger Agreement will require US Ecology to take any action, including disposing or transferring assets, licensing any technology or IP, holding separate any assets or operations of US Ecology and NRCG, that would, or would reasonably be expected to, result in a material reduction in the value (including any reasonably anticipated economic benefit to be received by Holdco and its subsidiaries, taken as a whole), measured either individually or in the aggregate, of US Ecology, NRCG and the combined companies, expected from the Mergers.

        No additional stockholder approval is expected to be required or sought for any decision by US Ecology or NRCG to agree to any terms and conditions necessary to resolve any regulatory objections to the Mergers.

Amended and Restated Certificate of Incorporation and Bylaws of Holdco

        Following the completion of the Mergers, the Holdco Amended Charter will be in substantially the same form attached as Annex E to this joint proxy statement/prospectus and the Holdco Amended Bylaws will be in substantially the same form attached as Annex F to this joint proxy statement/prospectus. Please see the section entitled "Comparison of Rights of US Ecology Stockholders, NRCG Stockholders and Holdco Stockholders" for a discussion of the Holdco Amended Charter.

Support Agreement, Investor Agreement and Registration Rights Agreement

Support Agreement

        Simultaneously with the execution of the Merger Agreement, US Ecology entered into the Support Agreement with Holdco, Rooster Merger Sub and the JFL Entities. As of each of the date of the Merger Agreement and the NRCG Record Date, the JFL Entities were the registered holders of approximately 66% of the currently issued and outstanding NRCG Common Stock. Pursuant to the Support Agreement, each of the JFL Entities agreed, during the term of the Support Agreement, to (1) appear at any NRCG common stockholders meeting or otherwise cause all of the shares of NRCG Common Stock owned by the JFL Entities entitled to vote thereat, as applicable, to be counted as present thereat for purposes of calculating a quorum, and (2) vote or cause to be voted (including by proxy or written consent, if applicable) all such shares entitled to vote thereat, as applicable, (a) in favor of the NRCG Merger Agreement Proposal, (b) in favor of the NRCG Adjournment Proposal, (c) against any action or proposal in favor of a Takeover Proposal (as defined in the Merger Agreement), without regard to the terms of such Takeover Proposal, and (d) against any action, proposal, transaction, agreement or amendment of NRCG's governing documents, in each case which would reasonably be expected to (i) result in a breach of any covenant, representation or warranty or any other obligation or agreement of NRCG contained in the Merger Agreement, or of the JFL Entities contained in the Support Agreement, or (ii) prevent, impede, interfere with, delay, postpone, or adversely affect the consummation of the transactions contemplated by the Merger Agreement, including the NRCG Merger. In addition, during the term of the Support Agreement, each of the JFL Entities appointed each of Jeffrey R. Feeler and Wayne R. Ipsen (or any other person acting as Chief Executive Officer or General Counsel of US Ecology and any designee thereof) and each of them

individually, as its proxy and attorney-in-fact, with full power of substitution and resubstitution, to vote or act by written consent during the term of the Support Agreement with respect to any and all of the shares of NRCG Common Stock held by the JFL Entities in accordance with the Support Agreement. As a result, and subject to the terms of the Support Agreement, the approval of the NRCG Merger Agreement Proposal is effectively assured.

        In addition, in the Support Agreement, each of the JFL Entities agreed, and agreed to cause its controlled affiliates (which, for the avoidance of doubt, does not include NRCG) and its and their representatives, not to take any action which, if it were taken by NRCG or its representatives, would violate the no shop provisions of the Merger Agreement. The Support Agreement (and the obligations of the JFL Entities thereunder) will terminate upon the earlier to occur of (1) the termination of the Merger Agreement in accordance with its terms, (2) the Effective Time, (3) such date that a Company Adverse Recommendation Change has been made in connection with determining that an Intervening Event (each as defined in the Merger Agreement) has occurred and (4) the termination of the Support Agreement by mutual written consent of the parties.

        The Support Agreement is attached hereto as Annex B.

Investor Agreement

        In connection with the execution of the Merger Agreement, US Ecology entered into the Investor Agreement with Holdco, the JFL Entities and, solely with respect to Section 4 thereof, NRCG, pursuant to which each of the JFL Entities agreed, among other things, to (1) a standstill for a period lasting until the earlier of (a) 120 days after the closing date of the Mergers and (b) the date the JFL Entities cease to own any Holdco Common Stock and (2) lock-up restrictions for a period of 60 days from the closing of the Mergers with respect to 1/3 of the shares held by the JFL Entities at closing of the Mergers, 90 days from the closing of the Mergers with respect to 1/3 of the shares held by the JFL Entities at closing of the Mergers and 120 days from the closing of the Mergers with respect to 1/3 of the shares held by the JFL Entities immediately following closing of the Mergers.

        In addition, pursuant to the Investor Agreement, JFL Partners irrevocably and unconditionally waived, effective immediately prior to the Effective Time, but subject to the consummation of the Mergers, any entitlement to any payment from NRCG pursuant to Section 5.18(b) of the 2018 Purchase Agreement. Section 5.18(b) of the 2018 Purchase Agreement contemplates the payment by NRCG to JFL Partners of up to $25.0 million upon the satisfaction of certain conditions set forth therein.

        The Investor Agreement is attached hereto as Annex C.

Registration Rights Agreement

        In connection with the execution of the Merger Agreement, US Ecology entered into the Registration Rights Agreement with Holdco and the JFL Entities. Under the Registration Rights Agreement, US Ecology agreed, as soon as reasonably practicable within 60 days after the Effective Time, to file with the SEC a shelf registration statement under the Securities Act on Form S-3 that covers all of the Registrable Securities (as defined in the Registration Rights Agreement) then held by the JFL Entities for a public offering to be made on a delayed or continuous basis pursuant to Rule 415 under the Securities Act and to use reasonable best efforts to cause such shelf registration statement to become effective immediately or as promptly thereafter as practicable. Pursuant to the Registration Rights Agreement, US Ecology granted the JFL Entities certain demand and piggyback registration rights with respect to the Registrable Securities. Any demand registration or demand takedown directed by the JFL Entities pursuant to the Registration Rights Agreement will be an underwritten offering, and US Ecology will have discretion to select a managing underwriter or underwriters to administrator the offering reasonably acceptable to the JFL Entities; provided, that the

131

JFL Entities agreed in advance that BofA Securities, Inc. is an acceptable managing underwriter or underwriter to administer such underwritten offering.

        The Registration Rights Agreement is attached hereto as Annex D.

Appraisal Rights

        Under the DGCL, holders of ECOL Common Stock and NRCG Common Stock are not entitled to appraisal rights in connection with the Mergers. Under the DGCL and the Merger Agreement, holders of NRCG Series A Preferred Stock are entitled to appraisal rights in connection with the NRCG Merger. See the section entitled "Appraisal Rights" of this joint proxy statement/prospectus.

Listing of Holdco Common Stock

        It is a condition to the completion of the Mergers that the shares of Holdco Common Stock to be issued to US Ecology stockholders or NRCG stockholders in the Mergers be authorized for listing on Nasdaq, subject to official notice of issuance, and Holdco, US Ecology and NRCG have agreed to use their reasonable best efforts to cause such shares (including shares of Holdco Common Stock reserved for issuance upon exercise of Holdco stock options and the Replacement Warrants) to be listed on Nasdaq. It is expected that following the Mergers, Holdco Common Stock will trade on Nasdaq under the symbol "ECOL." Following the Mergers, Holdco will be required to file periodic reports with the SEC with respect to Holdco Common Stock. In addition, the parties to the Merger Agreement intend for Holdco to list the Replacement Warrants on Nasdaq under the symbol "ECOLW" in connection with the closing of the Mergers.

Delisting and Deregistration of ECOL Common Stock

        If the Mergers are completed, ECOL Common Stock will be delisted from Nasdaq. US Ecology will no longer be required to file periodic reports with the SEC with respect to ECOL Common Stock. However, Holdco will be required to file periodic reports with the SEC with respect to Holdco Common Stock. However, Holdco Common Stock will be listed on Nasdaq and Holdco will be required to file periodic reports with the SEC.

Delisting and Deregistration of NRCG Securities

        If the Mergers are completed, NRCG Common Stock and NRCG Warrants will be delisted from the NYSE American and the NRCG Common Stock and NRCG Warrants will be deregistered under the Exchange Act. NRCG will no longer be required to file periodic reports with the SEC with respect to NRCG Common Stock or NRCG Warrants.

        To the extent requested by US Ecology, prior to the Effective Time, NRCG has agreed to cooperate with US Ecology and use its reasonable best efforts to take, or cause to be taken, all actions, and do or cause to be done all things, reasonably necessary, proper or advisable on its part under applicable laws and the rules and policies of the NYSE American to enable the delisting of the shares of NRCG Common Stock and NRCG Warrants from the NYSE American and the deregistration of the shares of NRCG Common Stock under the Exchange Act as promptly as practicable after the Effective Time, and in any event no more than ten days after the Effective Time.

The rights and obligations of US Ecology and NRCG are governed by the express terms and conditions of the Merger Agreement and not by this summary or any other information contained in this joint proxy statement/prospectus.

The Merger Agreement contains representations and warranties by each of the parties to the Merger Agreement.

        Accordingly, the representations and warranties and other provisions of the Merger Agreement should not be read alone, but instead should be read together with the information provided elsewhere in this joint proxy statement/prospectus and in the documents incorporated by reference into this joint proxy statement/prospectus. See the section entitled "Where You Can Find More Information" of this joint proxy statement/prospectus.

        This summary is qualified in its entirety by reference to the Merger Agreement.

Terms of the Mergers; Merger Consideration

        The Merger Agreement provides that, on the terms and subject to the conditions set forth in the Merger Agreement and in accordance with the DGCL, at the Effective Time, ECOL Merger Sub, a Delaware corporation and wholly-owned subsidiary of Holdco, will merge with and into US Ecology, and Rooster Merger Sub, a Delaware corporation and wholly-owned subsidiary of Holdco, will merge with and into NRCG. US Ecology and NRCG will be the surviving corporations in the Mergers and each will become a wholly-owned subsidiary of Holdco. Following the Mergers, Holdco intends to contribute all of the equity interests of NRCG to US Ecology so that, after such contribution, NRCG will be a wholly-owned subsidiary of US Ecology.

        At the Effective Time, each issued and outstanding share of ECOL Common Stock (other than shares owned by Holdco, ECOL Merger Sub, US Ecology or any of their respective subsidiaries, which will cease to remain outstanding and will be canceled and cease to exist) will be converted into the right to receive (1) 1.00 share of Holdco Common Stock and (2) any dividends or other distributions to which the holder thereof becomes entitled to upon the surrender of such shares of ECOL Common Stock

        At the Effective Time, each issued and outstanding share of NRCG Common Stock (other than shares owned by US Ecology, Holdco, Rooster Merger Sub, NRCG or any of their respective

133


Table of Contents

subsidiaries, which will cease to remain outstanding and will be canceled and cease to exist) will be converted into the right to receive, and become exchangeable for, (1) 0.196 of a share of Holdco Common Stock for each share of NRCG Common Stock, (2) any cash in lieu of fractional shares of Holdco Common Stock payable pursuant to the Merger Agreement and (3) any dividends or other distributions to which the holder thereof becomes entitled to upon the surrender of such shares of NRCG Common Stock in accordance with the Merger Agreement. Also at the Effective Time, each share of NRCG Series A Preferred Stock (other than shares owned by US Ecology, Holdco, Rooster Merger Sub, NRCG or any of their respective subsidiaries, which will cease to remain outstanding and will be canceled and cease to exist) will be converted into the right to receive, and become exchangeable for, (1) a whole number of shares of Holdco Common Stock equal to the product of (a) the number of shares of NRCG Common Stock that such share of NRCG Series A Preferred Stock could be converted into at the Effective Time (including, for the avoidance of doubt, the applicable Fundamental Change Additional Shares and Accumulated Dividends, each as defined in the NRCG Series A Certificate of Designations) multiplied by (b) the NRCG Exchange Ratio, (2) cash paid in lieu of fractional shares of Holdco Common Stock payable pursuant to the Merger Agreement and (3) any dividends or other distributions to which the holder thereof becomes entitled to upon the surrender of such shares of NRCG Series A Preferred Stock.

        Holdco will not issue fractional shares of Holdco Common Stock pursuant to the Merger Agreement. Instead, each holder of NRCG Common Stock or NRCG Series A Preferred Stock who otherwise would have been entitled to receive a fraction of a share of Holdco Common Stock will be entitled to receive a cash payment in lieu thereof in an amount (rounded to the nearest whole cent) equal to such fractional amount multiplied by an amount equal to the average of the daily volume weighted average price per share of ECOL Common Stock on Nasdaq (as such daily volume weighted average price per share is reported by Bloomberg L.P. or, if not reported therein, in another authoritative source mutually selected by US Ecology and NRCG) calculated for the five consecutive business days ending on the second full business day immediately prior to (and not including) the closing date of the Mergers.

        If, at any time from the date of the Merger Agreement until the Effective Time, any change in the number of issued and outstanding shares of NRCG capital stock or US Ecology capital stock (specifically excluding the issuance of additional shares of NRCG Common Stock or ECOL Common Stock as permitted by the Merger Agreement) shall occur by reason of any reclassification, recapitalization, stock split (including a reverse stock split), or combination, exchange, readjustment of shares, or similar transaction, or any stock dividend or distribution paid in stock, the amount of Holdco Common Stock to be issued as merger consideration in the Mergers and any other amounts payable pursuant to the Merger Agreement shall be appropriately adjusted to reflect such change.

NRCG Warrants

        At the Effective Time, and in accordance with the terms of each NRCG Warrant that is issued and outstanding immediately prior to the Effective Time, unless otherwise elected by the holder of any such NRCG Warrant, Holdco shall issue a Replacement Warrant that complies with and satisfies the applicable terms and conditions under the NRCG Warrant Agreement to each holder thereof providing that such replacement shall be exercisable for a number of shares of Holdco Common Stock equal to the product (rounded to the nearest whole number) of (1) the number of NRCG Common Stock that would have been issuable upon exercise of the warrants outstanding immediately prior to the Effective Time and (2) the NRCG Exchange Ratio, at an exercise price per share of Holdco Common Stock (rounded to the nearest whole cent) equal to the quotient obtained by dividing (a) $11.50 by (b) the NRCG Exchange Ratio.

134


Table of Contents

Completion of the Mergers

        Unless the parties agree otherwise, the closing of the Mergers will take place at 12:01 a.m., Boise, Idaho time, on the first business day of the calendar month after all conditions to the completion of the Mergers have been satisfied or waived. Notwithstanding the foregoing, unless otherwise agreed by US Ecology and NRCG in writing, the closing of the Mergers shall not occur prior to October 1, 2019. The Mergers will be effective when the parties file the certificates of merger with the Secretary of State of the State of Delaware in accordance with the DGCL, or at such later time as the parties agree and specify in the certificates of merger.

Exchange of Shares in the Mergers

        At or prior to the Effective Time, US Ecology will appoint an exchange agent to handle the exchange of shares of ECOL Common Stock, NRCG Common Stock and NRCG Series A Preferred Stock for shares of Holdco Common Stock in connection with the Mergers. At the Effective Time, shares of ECOL Common Stock, NRCG Common Stock and NRCG Series A Preferred Stock will be converted into the right to receive shares of Holdco Common Stock without the need for any action by the holders of ECOL Common Stock, NRCG Common Stock or NRCG Series A Preferred Stock.

        As promptly as reasonably practicable (but in no event later than ten business days) after the Effective Time, Holdco will cause the exchange agent to mail to each holder of record of ECOL Common Stock, NRCG Common Stock and NRCG Series A Preferred Stock a notice of the closing of the Mergers and a letter of transmittal specifying, among other things, that delivery shall be effected, and risk of loss and title shall pass, only upon proper delivery of the certificates or book-entry shares representing such ECOL Common Stock, NRCG Common Stock or NRCG Series A Preferred Stock, as applicable, to the exchange agent.

        After the Effective Time, shares of ECOL Common Stock, NRCG Common Stock and NRCG Series A Preferred Stock will no longer be outstanding, will be automatically canceled and will cease to exist and each certificate, if any, that previously represented shares of ECOL Common Stock, NRCG Common Stock or NRCG Series A Preferred Stock will represent only the right to receive the merger consideration as described above, any cash in lieu of fractional shares of Holdco Common Stock and any dividends or other distributions to which the holders are entitled with a record date after the Effective Time. With respect to such shares of Holdco Common Stock deliverable upon the surrender of ECOL Common Stock, NRCG Common Stock and NRCG Series A Preferred Stock, until holders of such ECOL Common Stock, NRCG Common Stock and NRCG Series A Preferred Stock have surrendered such ECOL Common Stock, NRCG Common Stock or NRCG Series A Preferred Stock, as applicable, to the exchange agent for exchange, those holders will not receive dividends or other distributions with respect to such shares of Holdco Common Stock with a record date after the Effective Time.

        At the Effective Time, US Ecology shall cause all shares of Holdco Common Stock that are issued and outstanding immediately prior to the Effective Time to be surrendered and cancelled and cease to exist, with no consideration delivered in exchange therefor.

        "Superior Proposal" means a bona fide written takeover proposal with respect to the applicable party or its subsidiaries (except that, for purposes of this definition, each reference in the definition of "takeover proposal" to "15%" shall be "50%"), that such party's board determines in good faith (after consultation with outside legal counsel and such party's financial advisor) is more favorable from a financial point of view to the holders of NRCG Common Stock or ECOL Common Stock, as applicable, than the transactions contemplated by the Merger Agreement, taking into account: (1) all financial considerations; (2) the anticipated timing, conditions (including any financing condition or the reliability of any debt or equity funding commitments) and prospects for completion of such takeover proposal; (3) the other terms and conditions of such takeover proposal and the implications thereof on such party, including relevant legal, regulatory, and other aspects of such takeover proposal deemed relevant by the NRCG Board or the US Ecology Board, as applicable; and (4) any revisions to the terms of the Merger Agreement and the Mergers proposed by US Ecology, in each case as the NRCG Board or the US Ecology Board, as applicable, has determined is appropriate in the exercise of its fiduciary duties.

        The Merger Agreement requires that NRCG and US Ecology, as applicable, promptly, and in any event no later than 24 hours, after such party receives (1) any takeover proposal, (2) any inquiry that would reasonably be expected to lead to a takeover proposal, or (3) any request for non-public information relating to NRCG or US Ecology, as applicable, or their respective subsidiaries in contemplation of a takeover proposal in respect of such party or its subsidiaries, to notify the other party in writing of any of the foregoing occurrences, the identity of the party making such request and the material terms and conditions of the takeover proposal. The applicable party will keep the other party fully informed, on a current basis (and in any event within 24 hours) of the status and material terms of any such takeover proposal, indication or request, including any material amendments or proposed amendments as to price and other material terms thereof. The applicable party shall promptly provide the other party with any non-public information concerning such party or such party's subsidiaries that it provided to any third-party in connection with any takeover proposal which was not previously provided to the other party.

Changes in Board Recommendations

        Each of the NRCG Board and the US Ecology Board has agreed that it will not (1) make, withdraw, amend, modify, or materially qualify, in a manner adverse to the other party, NRCG Board

recommendation or the US Ecology Board recommendation, as applicable, (2) fail to include the NRCG Board recommendation or US Ecology Board recommendation, as applicable, in this joint proxy statement/prospectus, (3) recommend a takeover proposal with respect to NRCG or US Ecology, as applicable, (4) fail to recommend against acceptance of any tender offer or exchange offer for shares of NRCG Common Stock or ECOL Common Stock, as applicable (that would, in the case of US Ecology, have the effect of precluding the Mergers) within ten days after the commencement of such offer, (5) fail to reaffirm (publicly, if so requested by NRCG or US Ecology, as applicable, which request shall only be made once per takeover proposal) the NRCG Board recommendation or the US Ecology Board recommendation within ten business days after the date any takeover proposal (or any material modification thereto) is first publicly disclosed, (6) cause or permit NRCG or US Ecology, as applicable, to enter into an alternative acquisition agreement or (7) resolve or agree to do any of the foregoing (each, a "NRCG Adverse Recommendation Change" or "US Ecology Adverse Recommendation Change," as applicable).

        Notwithstanding the restrictions described above, at any time prior to obtaining the relevant stockholder approval, the NRCG Board or US Ecology Board, as applicable, may, in response to any takeover proposal, make a NRCG Adverse Recommendation Change or US Ecology Adverse Recommendation Change, as applicable, if (1) the NRCG Board or US Ecology Board, as applicable, has determined in good faith, after consultation with its outside financial advisors and outside legal counsel, that such takeover proposal constitutes, or would reasonably expected to result in, a superior proposal, (2) the NRCG Board or US Ecology Board, as applicable, provides the other party four business days prior written notice of its intention to take such action, which notice expressly states that such party has a received a takeover proposal and such party's board of directors (or a committee thereof) intends to declare a superior proposal and intends to effect a NRCG Adverse Recommendation Change or a US Ecology Recommendation Change, as applicable, and shall include the current version of the proposed agreement and the identity of the third-party making such Superior Proposal, (3) during the four business days following such written notice, board of directors effecting the recommendation change and its representatives shall have negotiated in good faith with the other party regarding any revisions to the terms of the transactions contemplated by the Merger Agreement proposed by the other party in response to such takeover proposal so that the takeover proposal ceases to constitute a superior proposal and (4) at the end of the four business day period described in clause (3), the US Ecology Board or the NRCG Board (or a committee thereof), as applicable, concludes in good faith, after consultation with its outside legal counsel and financial advisor, that the takeover proposal continues to be a superior proposal. Any material amendment or modification to any takeover proposal requires an additional notice under clause (2) above and the negotiation period described in clause (3) above will be extended an additional two days from the date of receipt of such additional notice.

        In addition, at any time prior to obtaining the relevant stockholder approval, the NRCG Board or US Ecology Board, as applicable, may make a NRCG Adverse Recommendation Change or US Ecology Adverse Recommendation Change, as applicable, if (1) such board of directors determines that an "intervening event" (as defined in the section entitled "The Merger Agreement—Changes in Board Recommendations" of this joint proxy statement/prospectus) has occurred and is continuing and (2) such board of directors determines in good faith (after consultation with outside counsel) that the failure to make a NRCG Adverse Recommendation Change or a US Ecology Adverse Recommendation Change, as applicable, in response to such intervening event would constitute a breach of its fiduciary duties under applicable law; provided that (a) the NRCG Board or the US Ecology Board has given the other party at least four business days prior written notice of its intention to take such action and specifying in reasonable detail the circumstances related to such determination and (b) prior to effecting a NRCG Adverse Recommendation Change or a US Ecology Adverse Recommendation Change, the applicable party shall have negotiated, and have caused its representatives to negotiate, in good faith with the other party during such notice period, to enable such party to revise the terms of the Merger Agreement, such that the failure to make a NRCG Adverse Recommendation Change or a US Ecology Adverse Recommendation Change, as applicable, would not constitute a breach of its fiduciary duties under applicable law.

Table of Contents

        "Intervening event" means with respect to US Ecology or NRCG, as applicable, any material event, circumstance, change, effect, development, or condition effecting such party that has occurred or arose after the date of the Merger Agreement and that was not known to, nor reasonably foreseeable by, any member of such party's board of directors (assuming, for such purpose, reasonable consultation with the executive officers of such party), as of or prior to the date of the Merger Agreement and did not result from or arise out of the announcement or pendency of, or any actions required to be taken by such party (or to be refrained from being taken by such party) pursuant to, the Merger Agreement. In no event shall the following events, circumstances, or changes in circumstances constitute an intervening event: (1) the receipt, existence, or terms of a takeover proposal or any matter relating thereto or consequence thereof or any inquiry, proposal, offer, or transaction from any third-party relating to or in connection with a transaction of the nature described in the definition of "takeover proposal" (which, for the purposes of the intervening event definition, shall be read without reference to the percentage thresholds set forth in the definition thereof); or (2) any change in the price, or change in trading volume, of the NRCG Common Stock or ECOL Common Stock (provided, however, that the exception to this clause (2) shall not apply to the underlying causes giving rise to or contributing to such change or prevent any of such underlying causes from being taken into account in determining whether an intervening event has occurred).

Efforts to Obtain Required Stockholder Votes

        Under the terms of the Merger Agreement, NRCG and US Ecology have agreed that the NRCG Board and the US Ecology Board will each call, hold and convene a meeting of its common stockholders promptly after the declaration of effectiveness of the registration statement, of which this joint proxy statement/prospectus forms a part, by the SEC. NRCG and US Ecology have also agreed that the NRCG Board and the US Ecology Board will each use its reasonable best efforts to call, give notice of, convene and hold its respective special meetings on the same date.

        US Ecology and NRCG have also agreed to use their respective reasonable best efforts to obtain the requisite stockholder votes to consummate the Mergers. The US Ecology Board and the NRCG Board have each approved the Merger Agreement and declared the Merger Agreement and the transactions contemplated thereby, including the Mergers, advisable to and in the best interests of US Ecology and NRCG and their respective stockholders, as applicable, and adopted resolutions directing that the Merger Agreement be submitted to the US Ecology stockholders and the NRCG common stockholders, respectively, for their consideration as the US Ecology Special Meeting or the NRCG Special Meeting, as applicable.

        Unless the Merger Agreement is terminated prior to the date of the US Ecology Special Meeting, US Ecology must submit the US Ecology Merger Agreement Proposal, the Holdco Stock Issuance Proposal and the Holdco Charter Amendment Proposal to a stockholder vote even if the US Ecology Board no longer recommends that stockholders vote in favor of such proposals. Unless the Merger Agreement is terminated prior to the date of the NRCG Special Meeting, NRCG must submit the NRCG Merger Agreement Proposal to a stockholder vote even if the NRCG Board no longer recommends that stockholders vote in favor of such proposal.

Efforts to Complete the Mergers

        Each party to the Merger Agreement has agreed to use its reasonable best efforts to take all appropriate actions and to do all things reasonably necessary to consummate and make effective the transactions contemplated by the Merger Agreement, including using reasonable best efforts to obtain all waivers, permits, consents, approvals, authorizations, qualifications and orders of all governmental entities and parties to contracts with US Ecology, NRCG or any of their respective subsidiaries that may be or become necessary for the performance of obligations pursuant to the Merger Agreement and the consummation of the transactions thereunder.

Table of Contents

        Each of NRCG and US Ecology has agreed to make all filings required under the HSR Act with respect to the Mergers as promptly as reasonably practicable. In the case of the required Notification and Report Form under the HSR Act, each of US Ecology and JFL-AIV Investors III-JA, L.P. (on behalf of NRCG) filed its notification under the HSR Act on July 8, 2019. On July 16, 2019, each of US Ecology and JFL-AIV Investors III-JA, L.P. (as the controlling stockholder of NRCG) received early termination of the waiting period under the HSR Act. Accordingly, the condition to the Mergers related to obtaining that clearance has been satisfied.

        Notwithstanding the foregoing, US Ecology will not be required to (1) dispose or transfer any asset, including those of NRCG or the US Ecology; (2) license or otherwise make available to any person, any technology or other intellectual property of NRCG or US Ecology; (3) hold separate any assets or operations (either before or after the closing date) of NRCG or US Ecology; or (4) change or modify any course of conduct or otherwise making any commitment (to any governmental entity or otherwise) regarding future operations of US Ecology or NRCG's business to obtain any approval or clearance from any governmental or to prevent the initiation of any legal action by any governmental authority under the HSR Act or any other antitrust law or to prevent the entry of any decree, judgment, injunction (preliminary or permanent), or any order that would otherwise make the Merger Agreement, Mergers, or any contingent agreements unlawful if such action would result in any material reduction in the value (including any reasonably anticipated economic benefit to be received by Holdco and its subsidiaries, taken as a whole), measured either individually or in the aggregate of US Ecology, NRCG and the combined business, expected from the Mergers.

Governance Matters After the Mergers

        Immediately following the Effective Time, the board and executive officers of Holdco will be the board and executive officers of US Ecology immediately prior to the Mergers.

Employee Benefits Matters

        Each employee of NRCG or any of its subsidiaries who continues employment with Holdco or any of its subsidiaries following the closing date of the Mergers (each a "continuing employee") will continue to receive, through the date which is 12 months after the Effective Time (or if earlier, the date of such employee's termination of employment) an annual base salary or hourly wage rate, an annual target cash bonus opportunity amount (excluding equity-based compensation), and other employee benefits (excluding any equity and equity-based, change in control, retention, retiree welfare and defined benefit retirement benefits) that are, in the aggregate, substantially comparable to the annual base salary or hourly wage rate, annual target cash bonus opportunity amount (excluding equity-based compensation), and other employee benefits (excluding any equity and equity-based, change in control, retention, retiree welfare and defined benefit retirement benefits) provided by NRCG and its subsidiaries to such continuing employee on the date of the Merger Agreement, in any case, to the extent consistent with the terms of the governing plan documents. This obligation shall not apply to any continuing employee who is covered by a collective bargaining agreement or similar agreement.

        With respect to any "employee benefit plan" maintained by US Ecology or any of its subsidiaries (but excluding any retiree welfare plans or programs maintained by US Ecology or any of its subsidiaries, any defined benefit retirement plans or programs maintained by US Ecology or any of its subsidiaries, and any equity or equity-based compensation arrangements maintained by US Ecology or any of its subsidiaries) in which any continuing employees will be offered participation, effective as of the Effective Time, and subject to the terms of the governing plan documents, US Ecology shall, or shall cause the NRCG surviving company to, credit all service of the continuing employees with NRCG or any of its subsidiaries, as the case may be as if such service were with US Ecology, for purposes of eligibility to participate (but not for purposes of vesting or benefit accrual, except for vacation, if applicable) for full or partial years of service in any such US Ecology benefit plan; provided, that such

145

service shall not be credited to the extent that: (1) such crediting would result in a duplication of benefits; or (2) such service was not credited under the corresponding NRCG employee benefit plan.

Treatment of US Ecology Stock Options, Restricted Stock Units, Performance Stock Units and Restricted Shares

US Ecology Stock Options

        As of the Effective Time, each US Ecology stock option that is outstanding as of immediately prior to the Effective Time, whether or not then vested or exercisable, shall be automatically assumed by Holdco and shall be converted into an option to acquire the same number of shares of Holdco Common Stock as the number of shares of ECOL Common Stock subject to such US Ecology stock option as of immediately prior to the Effective Time, at the same exercise price per share of Holdco Common Stock as the exercise price per share of ECOL Common Stock of such US Ecology stock option as of immediately prior to the Effective Time; provided, that the exercise price and the number of shares of Holdco Common Stock subject to such replacement option shall be determined in a manner consistent with the requirements of Section 409A of the Code. Each such replacement option shall have, and shall be subject to, substantially the same terms and conditions as applied to the corresponding US Ecology stock option immediately prior to the Effective Time (including vesting, repurchase or other applicable restrictions). No US Ecology stock option shall become vested solely by reason of the execution of the Merger Agreement or the consummation of the transactions contemplated by the Merger Agreement.

US Ecology Restricted Stock Units

        As of the Effective Time, each US Ecology RSU that is outstanding as of immediately prior to the Effective Time shall be automatically assumed by Holdco and shall be converted into a RSU of Holdco covering the same number of shares of Holdco Common Stock as the number of shares of ECOL Common Stock covered by such US Ecology RSU as of immediately prior to the Effective Time. Each such replacement RSU shall have, and be subject to, substantially the same terms and conditions that were applicable to the corresponding US Ecology RSU immediately before the Effective Time. No US Ecology RSU shall become vested solely by reason of the execution of the Merger Agreement or the consummation of the transactions contemplated by the Merger Agreement.

US Ecology Performance Stock Units

        As of the Effective Time, each US Ecology PSU that is outstanding as of immediately prior to the Effective Time shall be automatically assumed by Holdco and shall be converted into a PSU of Holdco covering the same number of shares of Holdco Common Stock as the number of shares of ECOL Common Stock covered by such US Ecology PSU as of immediately prior to the Effective Time. Each such replacement PSU shall have, and be subject to, substantially the same terms and conditions that were applicable to the corresponding US Ecology PSU immediately before the Effective Time. No US Ecology PSU shall become vested solely by reason of the execution of the Merger Agreement or the consummation of the transactions contemplated by the Merger Agreement.

US Ecology Restricted Shares

        As of the Effective Time, each restricted share of ECOL Common Stock that is outstanding as of immediately prior to the Effective Time shall be assumed by Holdco and shall be converted into one share of restricted Holdco Common Stock. Each such replacement restricted share shall have, and be subject to, substantially the same terms and conditions as were applicable to the corresponding US Ecology restricted share immediately before the Effective Time. No US Ecology restricted share shall

146

become vested solely by reason of the execution of the Merger Agreement or the consummation of the transactions contemplated by the Merger Agreement.

Treatment of NRCG Stock Options and Restricted Stock Units

NRCG Stock Options

        As of the Effective Time, each NRCG stock option that is outstanding as of immediately prior to the Effective Time, whether or not then vested or exercisable, shall be automatically assumed by Holdco and shall be converted into a fully vested and immediately exercisable option to acquire that number of whole shares of Holdco Common Stock equal to the product (rounded down to the nearest whole share) of (1) the number of shares of NRCG Common Stock subject to such NRCG stock option as of immediately prior to the Effective Time and (2) the NRCG Exchange Ratio, at an exercise price per share of Holdco Common Stock (rounded up to the nearest whole cent) equal to the quotient obtained by dividing (a) the exercise price per share of NRCG Common Stock of such NRCG stock option as of immediately prior to the Effective Time by (b) the NRCG Exchange Ratio; provided, that the exercise price and the number of shares of Holdco Common Stock subject to such replacement option shall be determined in a manner consistent with the requirements of Section 409A of the Code. Each such replacement option shall have, and shall be subject to, substantially the same terms and conditions (other than vesting) as applied to the corresponding NRCG stock option immediately prior to the Effective Time, with such revisions as Holdco in its good faith discretion determines are necessary to reflect (1) the conversion of the applicable NRCG stock option into a replacement Holdco stock option, (2) the fact that such NRCG stock option is exercisable for shares of Holdco Common Stock and (3) the NRCG Merger.

NRCG Restricted Stock Units

        As of the Effective Time, each NRCG RSU that is outstanding as of immediately prior to the Effective Time shall be automatically assumed by Holdco and shall be converted into a RSU of Holdco covering that number of whole shares of Holdco Common Stock equal to the product (rounded to the nearest whole number) of (1) one and (2) the NRCG Exchange Ratio. Each such replacement RSU shall have, and be subject to, substantially the same terms and conditions that were applicable to the corresponding NRCG RSU immediately before the Effective Time, with such revisions as US Ecology in its good faith discretion determines are necessary to reflect (1) the conversion of the applicable NRCG RSU into a Holdco replacement RSU and (2) the NRCG Merger. No NRCG RSU shall become vested solely by reason of the execution of the Merger Agreement or the consummation of the transactions contemplated by the Merger Agreement.

Treatment of Equity Plans

        In connection with the closing of the Mergers, Holdco will assume each of the US Ecology, Inc. Omnibus Incentive Plan (the "ECOL Omnibus Plan"), the American Ecology Corporation 2008 Stock Option Incentive Plan (the "ECOL Option Plan") and the NRC Group Holdings Corp. 2018 Equity and Incentive Compensation Plan (the "NRCG Equity Plan"). The ECOL Option Plan and the NRCG Equity Plan will be assumed by Holdco solely for the purpose of replacing outstanding equity awards of US Ecology and NRCG with substantially similar equity awards of Holdco, as contemplated by the Merger Agreement. Similarly, the ECOL Omnibus Plan will be assumed by Holdco for the purpose of granting such replacement equity awards of Holdco as contemplated by the Merger Agreement; however, Holdco may also grant any future equity awards unrelated to the Mergers under the ECOL Omnibus Plan.

        Holdco will assume the ECOL Omnibus Plan and restate it as the US Ecology Parent, Inc. Omnibus Incentive Plan (the "Holdco Omnibus Plan") with substantially the same terms as those of

147


Table of Contents

the ECOL Omnibus Plan, except that the equity awards granted under the Holdco Omnibus Plan will be in respect of Holdco Common Stock. All awards granted under the ECOL Omnibus Plan that are assumed by Holdco at the Effective Time as contemplated by the Merger Agreement will be treated as if they were granted under the Holdco Omnibus Plan. The following general description of the material terms of the Holdco Omnibus Plan is qualified in its entirety by reference to the Holdco Omnibus Plan, which is filed as Annex G to this joint proxy statement/prospectus. In the event of any inconsistency between this summary and the Holdco Omnibus Plan, the Holdco Omnibus Plan will control.

        Administration—The Holdco Omnibus Plan will be administered by the Compensation Committee of the Holdco Board (the "Compensation Committee"). The Compensation Committee will have full and final authority in its discretion to (1) select the employees, non-employee directors and consultants who will receive awards, provided that awards granted to non-employee directors will be subject to ratification by the full Holdco Board; (2) determine the type or types of awards to be granted; (3) determine the number of shares to which an award will relate, the terms and conditions of any award (including, but not limited to, restrictions as to vesting, performance goals, transferability or forfeiture, exercisability or settlement and waivers or accelerations thereof, and waivers of or modifications to performance goals) and all other matters to be determined in connection with an award; (4) determine the exercise price, base price or purchase price (if any) of an award; (5) determine whether, to what extent, and under what circumstances an award may be cancelled, forfeited or surrendered; (6) determine how a leave of absence will impact an award, (7) determine whether, and to certify that, performance goals to which an award is subject are satisfied; (8) correct any defect or supply any omission or reconcile any inconsistency in the Holdco Omnibus Plan; (9) adopt, amend and rescind rules, regulations, guidelines, forms of agreements and instruments relating to the Holdco Omnibus Plan as it may deem necessary or advisable; (10) construe and interpret the Holdco Omnibus Plan; and (11) make all other determinations as it may deem necessary or advisable for the administration of the Holdco Omnibus Plan.

        Eligibility—Any person who serves as an employee or consultant to Holdco or any of its subsidiaries, as well as any of the non-employee directors of Holdco, will be eligible to receive awards under the Holdco Omnibus Plan.

        Limitation on Shares Available—The total number of shares available for awards under the Holdco Omnibus Plan will be 1,500,000, less the total number of shares issued under the ECOL Omnibus Plan. As of September 6, 2019, 627,983 shares were issued under the ECOL Omnibus Plan and 872,307 shares will be available for awards under the Holdco Omnibus Plan. For purposes of determining the number of shares available for awards, each award that is denominated in shares will count against this limit based on the number of shares underlying the award rather than any lesser number of shares that may be issued in settlement of the award. Any shares tendered by a participant in payment of an exercise price for or settlement of an award or the tax liability with respect to an award, will not be available for future awards under the Holdco Omnibus Plan. Any shares subject to an award or portion thereof that is cancelled or forfeited or otherwise does not result in the issuance of all shares subject thereto will again be available for grant under the Holdco Omnibus Plan. Shares may be reserved or made available from Holdco's authorized and unissued shares or from treasury shares. Shares issued on account of the assumption or substitution of outstanding grants from an acquired company will not reduce the number of shares available for awards. For the avoidance of doubt, shares of ECOL Common Stock issued pursuant to awards granted under the ECOL Omnibus Plan that are assumed by Holdco as contemplated by the Merger Agreement and converted to be in respect of Holdco Common Stock will be treated as if they were issued under the Holdco Omnibus Plan and will reduce the number of shares available for issuance under the Holdco Omnibus Plan.

Table of Contents

        Types of Awards—Under the Holdco Omnibus Plan, Holdco may grant awards of restricted stock, performance stock, options, stock appreciation rights ("SARs"), RSUs, PSUs and other stock-based awards or cash awards.

        Options.    Options give a participant the right to purchase a specified number of shares from Holdco for a specified time period at a fixed exercise price. Options granted may be either incentive stock options ("ISOs") or non-qualified stock options. The price at which an underlying share may be purchased will not be less than the fair market value of one share on the date of grant, or, in the case of an ISO granted to a ten-percent stockholder, less than 110% of the fair market value of a share on the date of grant. The Compensation Committee may grant options that have a term of up to ten (10) years, or, in the case of an ISO granted to a 10% stockholder, five years. The award agreement will specify the exercise price, term, vesting requirements, including any performance goals, and any other terms and conditions applicable to the option.

        Stock Appreciation Rights.    A grant of a SAR entitles a participant to receive, upon exercise of the SAR, the excess of (1) the fair market value of one share on the date of exercise, over (2) the per share base price of the SAR. No payment from the participant is required upon the exercise of a SAR. Each award agreement will specify the number of SARs granted, the base price of the SAR (which will not be less than 100% of the fair market value of a share on the date of grant), the time or times at which a SAR may be exercised in whole or in part, the method of exercise, the method of settlement, the method by which shares will be delivered or deemed to be delivered to a participant, the term of the SAR (which will not be greater than ten (10) years) and any other terms and conditions of the SAR.

        Restricted Stock.    An award of restricted stock is a grant of a specified number of shares to the participant, which shares are subject to forfeiture upon the happening of specified events during the restriction period. Each award of restricted stock will specify the duration of the restriction period, the conditions under which the shares may be forfeited, and the amount, if any, the participant must pay to receive the shares. During the restriction period, unless otherwise specified in an award agreement, the participant will have all of the rights of a stockholder with respect to the restricted stock, including the right to vote the shares and to receive dividends with respect to the shares.

        Performance Stock.    An award of performance stock is a grant of a specified number of shares to the participant subject to the achievement of performance goals during a specified performance period and subject to forfeiture upon the occurrence of specified events during the restriction period. Each award agreement will specify the duration of the performance period and restriction period (if any), performance goals applicable to the performance stock, the conditions under which the performance stock may be forfeited and the amount (if any) that the participant must pay to receive the performance stock. Unless otherwise provided in an award agreement, during the specified performance period the participant will not have the right to receive or accumulate dividends paid on or with respect to performance stock. However, the participant will have the right to receive dividends paid after the expiration of the performance period with respect to earned shares, whether or not such shares are subject to further restrictions.

        Restricted Stock Units.    A RSU award is a grant of the right to receive a payment in shares or cash, or a combination thereof, equal to the fair market value of one share on the expiration of the specified restriction period. During the restriction period, the participant will have no rights as a stockholder with respect to shares underlying RSUs. Each award agreement with respect to RSUs will specify the duration of the restriction period, if any, and/or each installment thereof and the conditions under which such award may be forfeited.

        Performance Stock Units.    A PSU award is a grant of the right to receive a payment in shares or cash, or a combination thereof, equal to the fair market value of one share (with or without a performance multiplier) on the expiration of the specified restriction period conditioned on the achievement of performance goals. During the restriction period, the participant will have no rights as a stockholder with respect to shares underlying PSUs. Each award agreement with respect to PSUs will specify the duration of the performance period and the restriction period, if any, the performance goals applicable to the PSUs and the conditions under which the PSUs may be forfeited.

        Other Stock-Based Awards.    The Compensation Committee may grant under the Holdco Omnibus Plan, subject to applicable law, any other type of award that is payable in, or valued in whole or in part by reference to, shares, and that is determined by the Compensation Committee to be consistent with the purposes of the Holdco Omnibus Plan. Such awards may include deferred shares or share purchase awards, as well as an outright grant of shares that are not subject to any vesting or other forfeiture conditions. Other stock-based awards will be subject to additional terms as determined by the Compensation Committee, in its sole discretion, consistent with the Holdco Omnibus Plan.

        Cash-based Awards.    Under the Holdco Omnibus Plan, the Compensation Committee may grant cash-based awards in such amounts and subject to such terms and conditions as it may determine consistent with the Holdco Omnibus Plan. Each cash-based award will specify a payment amount or payment range. Cash-based awards may be based on the attainment of performance goals.

        Effect of a Termination of Employment or Other Service—Unless otherwise provided in an award agreement or an effective employment, consulting, severance or similar agreement between a participant and Holdco or one of its subsidiaries, or as otherwise may be determined by the Compensation Committee, upon a participant's termination of employment or other service (1) at any time, due to death or disability or (2) within twenty-four (24) months following a change in control, without cause or by the participant for good reason, the unvested portion of each award held by the participant will vest in full, with any applicable performance goals being deemed to have been achieved at target or, if greater, actual levels, and any restricted period, if applicable, will lapse and such award will be settled (if necessary). If the participant holds an award of options or SARs, the award will remain exercisable by the participant or the participant's beneficiary or legal representative for ninety (90) days following the participant's termination.

        Unless otherwise provided in an award agreement or an effective employment, consulting, severance or similar agreement between a participant and Holdco or one of its subsidiaries, or as otherwise may be determined by the Compensation Committee, upon a participant's termination of employment or other service for any reason other than those specified in the immediately preceding paragraph, the unvested portion of each award held by the participant will cease to vest and will be forfeited with no further compensation due. If the participant holds an award of options or SARs, the vested portion of such award will remain exercisable for thirty (30) days following the participant's termination unless the termination was for cause, in which case options or SARs that were vested but unexercised will also be forfeited upon such termination.

        Qualifying Performance-Based Compensation—Under the Holdco Omnibus Plan, Holdco's Compensation Committee may, but is not required to, grant awards that will qualify as "performance-based compensation" under Section 162(m) of the Code in order to preserve the deductibility of such awards paid to a "covered employee" (as defined in Section 162(m) of the Code) for federal income tax purposes. Participants granted a qualifying performance-based compensation award are only entitled to receive payment to the extent that the participant satisfies pre-established performance goals, as set by Holdco's Compensation Committee, during a specified performance period. Any specified performance period will not be less than one year. Notwithstanding the foregoing, no awards granted on or after the Effective Time are intended to be a qualifying performance-based compensation award (other than certain awards granted by ECOL and assumed by Holdco in connection with the Mergers).

        Performance Goals—In the discretion of the Compensation Committee, the vesting, earning or settlement of any award may be conditioned upon the achievement of specified performance goals that are substantially uncertain to be met during the specified performance period at the time such goals are established. Performance goals may be described in terms of company-wide objectives or objectives that are related to the performance of the individual participant or a subsidiary, division, department or function within the company or subsidiary in which the participant is employed or to which the participant provides services. Performance goals may be measured on an absolute or relative basis.

150


Table of Contents

Relative performance may be measured by a group of peer companies, by a financial market index or by another external measure. Performance goals may be based upon: specified levels of or increases in return on capital, equity or assets; earnings measures/ratios (on a gross, net, pre-tax or post-tax basis), including diluted earnings per share, total earnings, operating earnings, earnings growth, earnings before interest and taxes (EBIT) and earnings before interest, taxes, depreciation and amortization (EBITDA); net economic profit; net income; operating income; safety and/or environmental record; sales; sales growth; gross margin; direct margin; share price (including but not limited to growth measures and total stockholder return), operating profit; operating efficiency; costs; per period or cumulative cash flow (including but not limited to operating cash flow and free cash flow) or cash flow return on investment (which equals net cash flow divided by total capital); inventory turns; financial return ratios; enterprise value; economic value added or other value added measurements; revenue; market share; balance sheet measurements such as receivable turnover; improvement in or attainment of expense levels; improvement in or attainment of working capital levels; debt reduction; strategic innovation, including but not limited to entering into, substantially completing, or receiving payments under, relating to, or deriving from a joint development agreement, licensing agreement, or similar agreement; completion of acquisitions, business expansion or divestitures; implementation of critical projects or related milestones; achievement of operational or efficiency milestones; customer or employee satisfaction; individual objectives; any financial or other measurement deemed appropriate by the Compensation Committee as it relates to the results of operations or other measurable progress; and any combination of any of the foregoing criteria. If the Compensation Committee determines that a change in Holdco's business, operations, corporate structure or capital structure of the company or a subsidiary, or other events or circumstances render the performance goals unsuitable, then the Compensation Committee may modify such performance goals and/or the related minimum, target, maximum and/or other acceptable levels of achievement as may be deemed appropriate and equitable.

        Changes in Capitalization and Change in Control—In the event that the Compensation Committee determines that any stock dividend, recapitalization, forward split or reverse split, reorganization, merger, consolidation, spin-off, combination, repurchase or share exchange, extraordinary or unusual cash distribution or other similar corporate transaction or event, affects Holdco's shares such that an adjustment is appropriate in order to prevent dilution or enlargement of the rights of participants in the Holdco Omnibus Plan, then the Compensation Committee will proportionately and equitably adjust any or all of (1) the number and kind of shares which may thereafter be issued in connection with awards, (2) the number and kind of shares issuable in respect of outstanding awards, (3) the aggregate number and kind of shares available for issuance, and (4) the exercise price or grant price relating to any award or, if deemed appropriate, make provision for a cash payment with respect to any outstanding award.

        Unless otherwise provided in an award agreement or an effective employment, consulting, severance or similar agreement, a change in control will not, in and of itself, accelerate the vesting, settlement or exercisability of outstanding awards. Notwithstanding the foregoing (and unless otherwise provided in an award agreement or an effective employment, consulting, severance or similar agreement), if, in connection with a change in control, (1) the successor corporation (or its parent) does not assume an outstanding award or does not agree to substitute or replace such award with an award involving the ordinary common shares of such successor corporation (or its parent) on terms and conditions that preserve the rights of the applicable participant with respect to such award, (2) the securities of Holdco or the successor corporation after the change in control will not be publicly traded on a U.S. securities exchange or (3) the change in control is not approved by a majority of incumbent directors immediately prior to such change in control, the Compensation Committee, in its sole discretion, may take one or more of the following actions with respect to all, some or any such awards: (a) accelerate the vesting, settlement and, if applicable, exercisability of such awards such that the awards are fully vested, settled and, if applicable, exercisable (effective immediately prior to such change in control); provided that awards subject to performance-based vesting conditions will be paid

151


Table of Contents

or settled in full based on the greater of the actual or target level (or, in the case of a change in control described in clause (2), maximum level) of achievement of the applicable performance goals through the date of the change in control; (b) cancel outstanding options or SARs in exchange for a cash payment in an amount equal to the excess, if any, of the fair market value of the options or SARs unexercised as of the date of the change in control over the exercise price or base price, as the case may be, of such shares (provided that any option or SAR with an exercise price or base price, as the case may be, that equals or exceeds the fair market value of one share on the date of the change in control will be cancelled with no payment due); or (c) take such other actions as the Compensation Committee deems appropriate to preserve the rights of participants with respect to their awards. The determination of the Compensation Committee with respect to any action taken in connection with a change in control will be conclusive and binding upon each participant.

        Amendment and Termination—The Holdco Board may amend, alter, suspend, discontinue or terminate the Holdco Omnibus Plan without the consent of any participant or stockholders, except that any such amendment, alteration, suspension, discontinuation or termination will be subject to the approval of the stockholders if (1) such action would increase the number of shares available for awards, (2) such action results in the repricing, replacement or cash buyout/repurchase of any option, SAR or other award, or (3) stockholder approval is required by applicable law or regulation or the rules of any stock exchange on which the shares may then be listed. Notwithstanding the foregoing, without the consent of an affected participant, no amendment, alteration, suspension, discontinuation or termination of the Holdco Omnibus Plan may materially adversely affect the rights of a participant under any outstanding award, except insofar as any such action is necessary to ensure compliance with applicable law or regulation or the listing requirements of an applicable securities exchange, including, without limitation, Sections 162(m) or 409A of the Code. Unless earlier terminated, the Holdco Omnibus Plan will terminate on April 7, 2025.

Employee Benefits Actions between Signing of Merger Agreement and Completion of Mergers

        Under the terms of the Merger Agreement, NRCG may not, without the prior consent of US Ecology (which consent shall not be unreasonably withheld, conditioned or delayed) increase the compensation or benefits of any of its directors, officers, employees or consultants, other than (1) increases in compensation for non-officer employees in the ordinary course of business consistent with past practice, provided that such increases are not, in the aggregate, material to NRCG or any of its Subsidiaries, (2) as required by the terms of any NRCG employee benefit plan as in effect as of immediately prior to the date of the Merger Agreement, or (3) as required by law. In addition, NRCG may not, without the prior written consent of US Ecology (which consent shall not be unreasonably withheld, conditioned or delayed) (a) promote any officers or employees of NRCG or its subsidiaries, except in connection with NRCG's annual or quarterly compensation review cycle or as the result of the termination or resignation of any officer or employee, (b) hire or terminate other than for cause (or provide a notice of termination other than for cause to) any officer, employee or consultant whose annualized total compensation exceeds $150,000, or (c) establish, adopt, enter into, materially amend, terminate, or materially modify any NRCG employee benefit plan except as required by law or by the terms of any NRCG employee benefit plan in effect as of the signing of the Merger Agreement.

Other Covenants and Agreements

        The Merger Agreement contains certain other covenants and agreements, including covenants relating to:

152


Table of Contents

        Under the Merger Agreement, following the completion of the Mergers, the combined company will assume all rights to indemnification, advancement of expenses and exculpation from liabilities for acts or omissions occurring at or prior to the Effective Time existing in favor of the current or former directors and officers of NRCG. Following completion of the Mergers, Holdco will obtain a "tail" officers' and directors insurance policy for the benefit of the officers and directors of NRCG and its subsidiaries prior to the Effective Time. The policy will be in place for six years after the Mergers and provide coverage that is at least the same coverage and amounts and containing terms and conditions that are not less advantageous to the indemnified parties than the terms of the directors' and officers' liability insurance policy maintained by NRCG as of the signing of the Merger Agreement. However, Holdco will not be required to expend in any one year an amount in excess of 300% of the last annual premium paid by NRCG at the time the Merger Agreement was signed. In the event the premium exceeds 300% of the last annual premium at the time the Merger Agreement was signed, Holdco will be obligated to obtain an insurance policy with the greatest coverage available for a cost equal to 300% of the annual premium at the time the Merger Agreement was signed.

Conditions to Completion of the Mergers

        Each party's obligation to consummate the Mergers is conditioned upon the satisfaction (or, to the extent permitted by applicable law, waiver by such party) at or prior to the closing of the Mergers of each of the following:

153

Termination of the Merger Agreement

        The Merger Agreement may be terminated at any time prior to the Effective Time, even after the receipt of the required stockholder approvals, under the following circumstances:

156


Table of Contents

        In the event of a valid termination of the Merger Agreement, written notice will be given by the terminating party to the other party specifying the reasons for such termination. In the event of a valid termination of the Merger Agreement, the Merger Agreement will be terminated and will become void and have no effect, without any liability or obligation on the part of any party, except that certain provisions regarding termination fees and other general matters will survive such termination. The termination of the Merger Agreement will not affect the obligations of the parties contained in the confidentiality agreements between NRCG and US Ecology dated March 23, 2019 and March 25, 2019.

Expenses and Termination Fees; Liability for Breach

        Each party shall pay all fees and expenses incurred by it in connection with the Mergers and the other transactions contemplated by the Merger Agreement, provided, however that the parties will share equally all fees and expenses incurred in connection with the HSR Act.

        NRCG will be obligated to pay a termination fee of $35 million to US Ecology if:

157


Table of Contents

        US Ecology will be obligated to pay a termination fee of $60 million to NRCG if:

        In addition, if the Merger Agreement is terminated by US Ecology or NRCG because the US Ecology requisite stockholder vote is not obtained, then US Ecology shall pay to NRCG up to $10.0 million of the reasonable and documented out-of-pocket fees and expenses of NRCG incurred in connection with or related to the authorization, preparation, negotiation, execution and performance of the Merger Agreement and the transactions contemplated thereby

Amendments, Extensions and Waivers

        The Merger Agreement may be amended or supplemented by the parties to the Merger Agreement at any time before or after the receipt of the approvals of the NRCG common stockholders and US Ecology stockholders required to consummate the Mergers. Notwithstanding the foregoing, after approval of the Merger Agreement by the NRCG common stockholders and/or US Ecology stockholders, there may not be, without further approval of such stockholders, any amendment or supplement to the Merger Agreement which by applicable law or in accordance with any applicable self-regulatory organization would require stockholder approval.

        At any time prior to the Effective Time, any party may (1) extend the time for performance of any obligations or other acts of the other party or parties, (2) waive any inaccuracies in the representations and warranties of the other party or parties contained in the Merger Agreement or any document delivered under the Merger Agreement and (3) unless otherwise prohibited by applicable law, waive compliance by the other parties with any of the agreements or conditions contained in the Merger Agreement

158


Table of Contents

Parties in Interest

        Nothing in the Merger Agreement, express or implied, confers upon any person other than the parties (and their respective successors and permitted assigns) any right, benefit or remedy of any nature whatsoever under or by reason of the Merger Agreement, except that for six years from the Effective Time, the combined company will indemnify each present (as of the Effective Time) and former director and officer of NRCG or its subsidiaries (in each case, when acting in such capacity) against all claims, losses, liabilities, damages, judgments, inquiries, fines and reasonable fees, costs and expenses incurred in connection with any action pertaining to matters existing or occurring at or prior to the Effective Time. In addition, the Merger Agreement contains certain provisions in favor of potential debt financing sources in connection with the US Ecology debt financing contemplated by the Merger Agreement. For more information, see the section entitled "The Mergers—Indebtedness Following the Mergers."

        For additional information regarding indemnification of directors and officers, see the section entitled "The Merger Agreement—Other Covenants and Agreements" of this joint proxy statement/prospectus.

Specific Performance

        NRCG and US Ecology have agreed in the Merger Agreement that irreparable damage would occur in the event that any of the provisions of the Merger Agreement were not performed in accordance with their specific terms or were otherwise breached. To that end, the parties agreed that each will be entitled to an injunction or injunctions to prevent actual or threatened breaches of the Merger Agreement and to enforce specifically the performance of terms and provisions of the Merger Agreement. The parties further waived the defense of adequacy of remedies at law as a prerequisite to obtaining equitable relief.

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE MERGERS

        The following is a general discussion of the U.S. federal income tax consequences of the Mergers to U.S. holders of ECOL Common Stock, NRCG Common Stock, NRCG Warrants and NRCG Series A Preferred Stock.

        This discussion is based on the Code, applicable U.S. Treasury regulations, administrative interpretations and court decisions, each as in effect as of the date of this joint proxy statement/prospectus and all of which are subject to change, possibly with retroactive effect. Any such change could affect the validity of this discussion. This discussion addresses only holders of ECOL Common Stock, NRCG Series A Preferred Stock, NRCG Warrants and NRCG Common Stock that hold their stock as a capital asset within the meaning of Section 1221 of the Code (generally, property held for investment). This discussion does not address any non-income taxes or any foreign, state or local tax consequences including any unearned income Medicare contribution tax pursuant to the Health Care and Reconciliation Act of 2010, or to holders subject to special rules, including, without limitation:

        For purposes of this discussion, a "U.S. holder" is a beneficial owner of ECOL Common Stock, NRCG Series A Preferred Stock, NRCG Warrants or NRCG Common Stock that is:

        If a partnership (or an entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds ECOL Common Stock, NRCG Series A Preferred Stock, NRCG Warrants or NRCG Common Stock, the tax treatment of a partner will generally depend on the status of the partner and the activities of the partnership. Partners of partnerships holding ECOL Common Stock, NRCG

Series A Preferred Stock, NRCG Warrants or NRCG Common Stock should consult their own tax advisors.

        THE FOLLOWING DISCUSSION DOES NOT PURPORT TO BE A COMPLETE ANALYSIS OR DISCUSSION OF ALL OF THE POTENTIAL TAX CONSEQUENCES OF THE MERGERS. PLEASE CONSULT YOUR OWN TAX ADVISORS AS TO THE SPECIFIC TAX CONSEQUENCES TO YOU OF THE MERGERS, INCLUDING TAX RETURN REPORTING REQUIREMENTS AND THE APPLICABILITY AND EFFECT OF U.S. FEDERAL, STATE, LOCAL AND FOREIGN INCOME AND OTHER TAX LAWS IN LIGHT OF YOUR PARTICULAR CIRCUMSTANCES.

General

        US Ecology and NRCG intend that, for U.S. federal tax purposes, the Mergers will qualify as a "reorganization" within the meaning of Section 368(a) of the Code or, alternatively the NRCG Merger, together with the ECOL Merger, will be treated as an "exchange" described in Section 351 of the Code. It is a condition to US Ecology's and NRCG's obligations to complete the Mergers that each of US Ecology and NRCG receive an opinion from Dechert or Jones Day, dated as of the closing date, to the effect that, in the case of US Ecology, the Mergers will each qualify as a "reorganization" within the meaning of Section 368(a) of the Code or, alternatively, the Mergers together will be treated as an "exchange" described in Section 351 of the Code and, in the case of NRCG, the NRCG Merger will qualify as a "reorganization" within the meaning of Section 368(a) of the Code or, alternatively, the NRCG Merger, taken together with the ECOL Merger, will be treated as an "exchange" described in Section 351 of the Code.

        These opinions will be based on customary assumptions and representations from US Ecology and NRCG, as well as certain covenants and undertakings by Holdco, US Ecology, NRCG, Rooster Merger Sub and ECOL Merger Sub. If any of the assumptions, representations, covenants or undertakings is incorrect, incomplete or inaccurate or is violated, the validity of the opinions described above may be affected and the tax consequences of the Mergers could differ, perhaps substantially, from those described in this joint proxy statement/prospectus.

        An opinion of counsel represents counsel's best legal judgement but is not binding on the Internal Revenue Service (the "IRS") or any court, so there can be no certainty that the IRS will not challenge the conclusions reflected in the opinion or that a court would not sustain such a challenge. Neither US Ecology nor NRCG intends to obtain a ruling from the IRS regarding the qualification of each of the Mergers as a "reorganization" within the meaning of Section 368(a) of the Code nor of the treatment of the Mergers together as an "exchange" described in Section 351 of the Code. If the IRS were to successfully challenge the treatment of the Mergers described above, the tax consequences could differ, perhaps substantially, from those described in this joint proxy statement/prospectus. The following discussion assumes the receipt and accuracy of the opinions described above.

U.S. Federal Income Tax Consequences of the Mergers to U.S. Holders of ECOL Common Stock, NRCG Series A Preferred Stock, NRCG Warrants and NRCG Common Stock

Exchange of ECOL Common Stock, NRCG Series A Preferred Stock and NRCG Common Stock for Holdco Common Stock

        Subject to the discussions below relating to the receipt of cash in lieu of fractional shares of Holdco Common Stock payable pursuant to the Merger Agreement and the exchange of NRCG

161


Table of Contents

Warrants, a U.S. holder of ECOL Common Stock, NRCG Series A Preferred Stock or NRCG Common Stock that receives shares of Holdco Common Stock in connection with the Mergers:

Cash in Lieu of Fractional Shares

        A U.S. holder that receives cash in lieu of a fractional share of Holdco Common Stock generally will be treated as having received such fractional share as merger consideration and then as having received the cash in exchange for such fractional share. Gain or loss generally will be recognized based on the difference between the amount of cash received in lieu of the fractional share and the tax basis allocated to such fractional share of Holdco Common Stock.

        Any gain (or loss) with respect to a fractional share recognized by a U.S. holder generally will be long-term capital gain (or loss) if the U.S. holder's shares of NRCG Series A Preferred Stock or NRCG Common Stock exchanged for the merger consideration are held as a capital asset by the U.S. holder and, as of the Effective Time, the holding period for such shares is greater than one year, which generally includes the holding period of capital assets exchanged for those shares in a prior transaction treated as a "reorganization" within the meaning of Section 368(a) of the Code or an "exchange" described in Section 351 of the Code.

        U.S. holders that acquired different blocks of NRCG Common Stock or NRCG Series A Preferred Stock at different times or different prices should consult their tax advisor regarding the manner in which gain or loss should be determined in their specific circumstances.

Exchange of NRCG Warrants for Replacement Warrants

        If the NRCG Merger qualifies as a "reorganization" within the meaning of Section 368(a) of the Code, a U.S. holder of NRCG Warrants that receives Replacement Warrants in connection with the NRCG Merger will:

        If the NRCG Merger does not qualify as a "reorganization" within the meaning of Section 368(a) of the Code and, assuming the NRCG Merger, together with the ECOL Merger, will be treated as an

162


Table of Contents

"exchange" described in Section 351 of the Code, a U.S. holder that exchanges solely NRCG Warrants for Replacement Warrants in the NRCG Merger will:

Exchange of NRCG Warrants and NRCG Common Stock and/or NRCG Series A Preferred Stock for Replacement Warrants and Holdco Common Stock

        If the NRCG Merger does not qualify as a "reorganization" within the meaning of Section 368(a) of the Code and, assuming the NRCG Merger, together with the ECOL Merger, will be treated as an "exchange" described in Section 351 of the Code, a U.S. holder that exchanges NRCG Warrants in addition to NRCG Common Stock and/or NRCG Series A Preferred Stock for Replacement Warrants and Holdco Common Stock in the NRCG Merger will:

        U.S. holders of NRCG Warrants are urged to consult with their own tax advisors as to the specific tax consequences to you of the Mergers.

Information Reporting and Backup Withholding

        Certain U.S. holders of NRCG Common Stock or NRCG Series A Preferred Stock may be subject to information reporting and backup withholding of U.S. federal income tax with respect to any cash received in lieu of fractional shares of Holdco Common Stock pursuant to the Mergers. Backup withholding will not apply, however, to a U.S. holder that furnishes a correct taxpayer identification number and certifies that it is not subject to backup withholding on IRS Form W-9 or is otherwise exempt from backup withholding and provides proof of the applicable exemption. Backup withholding is not an additional tax and any amounts withheld will be allowed as a refund or credit against the U.S. holder's U.S. federal income tax liability, if any, provided that such U.S. holder timely furnishes the required information to the IRS.

ACCOUNTING TREATMENT

        Holdco will prepare its financial statements in accordance with GAAP. The Mergers will be accounted for using the acquisition method of accounting with US Ecology being considered the acquirer of NRCG for accounting purposes under Accounting Standards Codification Topic 805, Business Combinations ("ASC 805"). This means that US Ecology will allocate the purchase consideration to the fair value of NRCG tangible and intangible assets and liabilities at the acquisition date, with the excess purchase consideration being recorded as goodwill. Under the acquisition method of accounting, goodwill is not amortized but is tested for impairment at least annually.

        US Ecology was determined to be the accounting acquirer based on an assessment of the criteria outlined in ASC 805 and the facts and circumstances specific to the Mergers, including that, following the closing of the Mergers, (1) stockholders of US Ecology are expected to own a majority of the voting interests of Holdco, (2) the composition of the Holdco Board will be identical to the US Ecology Board immediately prior to the closing of the Mergers and (3) the composition of the management team of Holdco will be identical to the composition of the management team of the US Ecology immediately prior to the closing of the Mergers. As a result, the historical financial statements of US Ecology will become the historical financial statements of Holdco.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

        The unaudited pro forma condensed combined balance sheet as of June 30, 2019, combines the historical consolidated balance sheets of US Ecology and NRCG, giving effect to the Mergers as if they had occurred on June 30, 2019. The unaudited pro forma condensed combined statement of operations for the six months ended June 30, 2019 and for the year ended December 31, 2018 combine the historical consolidated statements of operations of US Ecology and NRCG, giving effect to the Mergers as if they had occurred on January 1, 2018, the first day of the fiscal year ended December 31, 2018. The historical financial statements of US Ecology and NRCG, which are included elsewhere or incorporated by reference in this joint proxy statement/prospectus have been adjusted in the unaudited pro forma condensed combined financial statements to give pro forma effect to events that are (i) directly attributable to the Mergers, (ii) factually supportable, and (iii) with respect to the statements of operations, expected to have a continuing impact on the combined company's results.

        The unaudited pro forma condensed combined financial statements give effect to the Mergers. The unaudited pro forma condensed combined financial statements have been prepared by US Ecology in accordance with the regulations of the SEC. Based on a comprehensive review of the requirements of ASC 805, Business Combinations, US Ecology management concluded that US Ecology is the accounting acquirer based on a number of factors, including (i) stockholders of US Ecology are expected to own a majority of the voting rights of Holdco, (ii) the composition of the Holdco Board will be identical to the US Ecology Board immediately prior to the closing of the Mergers and (iii) the composition of the management team of Holdco will be identical to the composition of the management team of the US Ecology immediately prior to the closing of the Mergers. As a result, the historical financial statements of US Ecology will become the historical financial statements of Holdco. The Mergers are considered a business combination and therefore the unaudited pro forma condensed combined financial statements have been prepared using the acquisition method of accounting under GAAP. Under the acquisition method of accounting for purposes of these unaudited pro forma condensed combined financial statements, management of US Ecology and NRCG have determined a preliminary estimated purchase price, calculated as described in Note 2 to these unaudited pro forma condensed combined financial statements. The NRCG assets acquired and liabilities assumed in connection with the Mergers are recorded at their estimated acquisition date fair values. A final determination of these estimated fair values will be based on the actual net assets of NRCG that exist as of the date of completion of the Mergers.

        The unaudited pro forma condensed combined financial statements are based on the assumptions and adjustments that are described in the accompanying notes and have been presented for informational purposes only. The unaudited pro forma condensed combined financial statements and pro forma adjustments have been prepared based on preliminary estimates of fair value of assets acquired and liabilities assumed using estimates and assumptions that US Ecology believes are reasonable based on the information that is currently available to it. Differences between these preliminary estimates and the final acquisition accounting will occur and those differences could have a material impact on the accompanying unaudited pro forma condensed combined financial statements and the combined company's future results of operations and financial position. The actual amounts recorded as of the completion of the Mergers may differ materially from the information presented in these unaudited pro forma combined financial statements as a result of the amount of cash used by NRCG operations prior to the closing of the Mergers, changes in the fair value of a share of NRCG Common Stock, the timing of the closing of the Mergers, and other changes in NRCG assets and liabilities that occur prior to the completion of the Mergers.

        The unaudited pro forma condensed combined financial statements do not give effect to the potential impact of current financial conditions, regulatory matters, operating efficiencies, synergies or other savings or expenses that may be associated with the integration of the two companies. The

unaudited pro forma condensed combined financial statements have been prepared for illustrative purposes only and are not necessarily indicative of the financial position or results of operations in future periods or the results that actually would have been realized had US Ecology and NRCG been a combined company during the specified periods.

NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

NOTE 1. DESCRIPTION OF TRANSACTION AND BASIS OF PRO FORMA PRESENTATION

Description of Transaction

        On June 23, 2019, US Ecology, Holdco, ECOL Merger Sub, Rooster Merger Sub and NRCG entered into the Merger Agreement. Under the terms of the Merger Agreement, ECOL Merger Sub will merge with and into US Ecology, with US Ecology as the surviving entity and continuing as a wholly-owned subsidiary of Holdco and, simultaneously therewith, Rooster Merger Sub will merge with and into NRCG, with NRCG as the surviving entity and continuing as a wholly-owned subsidiary of Holdco.

        In the ECOL Merger, each share of ECOL Common Stock issued and outstanding immediately prior to the Effective Time (other than cancelled shares) will be converted into the right to receive (1) one share of Holdco Common Stock and (2) any dividends or other distributions to which the holder thereof becomes entitled to upon the surrender of shares of ECOL Common Stock in accordance with the Merger Agreement. Outstanding equity awards of US Ecology will be assumed by Holdco and converted into equity awards at Holdco on a one-for-one basis as set forth in the Merger Agreement and described herein under the section entitled "The Merger Agreement—Treatment of US Ecology Stock Options, Restricted Stock Units, Performance Stock Units and Restricted Shares." Each share of ECOL Common Stock that is held by US Ecology as treasury stock or that is owned by Holdco, ECOL Merger Sub, US Ecology or any of their respective direct or indirect wholly-owned subsidiaries as of immediately prior to the Effective Time will automatically be cancelled and will cease to exist, without any conversion thereof, and no consideration will be delivered in exchange therefor.

        In the NRCG Merger, each share of NRCG Common Stock issued and outstanding immediately prior to the Effective Time (other than cancelled shares) will be converted into the right to receive, and become exchangeable for (1) 0.196 of a share of Holdco Common Stock for each share of NRCG Common Stock, (2) any cash in lieu of fractional shares of Holdco Common Stock payable pursuant to the Merger Agreement and (3) any dividends or other distributions to which the holder thereof becomes entitled to upon the surrender of such shares of NRCG Common Stock in accordance with the Merger Agreement. Each share of NRCG Series A Preferred Stock issued and outstanding immediately prior to the Effective Time will be converted into the right to receive, and become exchangeable for (1) a whole number of shares of Holdco Common Stock equal to the product of (a) the number of shares of NRCG Common Stock that such share of NRCG Series A Preferred Stock could be converted into at the Effective Time (including Fundamental Change Additional Shares and Accumulated Dividends (each as defined in the NRCG Series A Certificate of Designation)) multiplied by (b) the NRCG Exchange Ratio, (2) any cash in lieu of fractional shares of Holdco Common Stock payable pursuant to the Merger Agreement and (3) any dividends or other distributions to which the holder thereof becomes entitled to upon the surrender of such shares of NRCG Series A Preferred Stock in accordance with the Merger Agreement. In the NRCG Merger, each share of NRCG Common Stock or NRCG Series A Preferred Stock that is owned by NRCG, Rooster Merger Sub or any of their respective direct or indirect wholly-owned subsidiaries immediately prior to the Effective Time will automatically be cancelled and will cease to exist, without any conversion thereof, and no consideration will be delivered in exchange therefor.

        Also at the Effective Time, US Ecology shall cause all shares of Holdco Common Stock that are issued and outstanding immediately prior to the Effective Time to be surrendered and cancelled and cease to exist, with no consideration delivered in exchange therefor.

        At the Effective Time and by virtue of the NRCG Merger, in exchange for each outstanding NRCG Warrant issued pursuant to the NRCG Warrant Agreement, between Continental Stock Transfer & Trust Company and NRCG, unless otherwise elected by the holder of any such NRCG Warrant, Holdco will issue a Replacement Warrant that complies with and satisfies the applicable terms

170


Table of Contents

and conditions under the Warrant Agreement to each holder of an NRCG Warrant providing that such Replacement Warrant will be exercisable for a number of shares of Holdco Common Stock equal to the product (rounded to the nearest whole number) of (1) the number of shares of NRCG Common Stock that would have been issuable upon the exercise of the NRCG Warrant immediately prior to the Effective Time and (2) the NRCG Exchange Ratio, at an exercise price equal to the quotient obtained by dividing (a) the pre-NRCG Merger exercise price ($11.50 per share) by (b) the NRCG Exchange Ratio. Following the closing of the Mergers, Holdco will comply with all terms and conditions set forth in each such Replacement Warrant.

        Outstanding shares of NRCG equity awards will be converted into equity awards of Holdco pursuant to the mechanics set forth in the Merger Agreement and described herein under the section entitled "The Merger Agreement—Treatment of NRCG Stock Options and Restricted Stock Units."

        In addition, US Ecology intends to incur a new $450.0 million seven-year term loan (the "Term Loan"), the proceeds of which will be used to immediately repay NRCG's existing term loan and revolving credit facility and to pay transaction fees and expenses associated with the Mergers, with the remaining proceeds used to pay down US Ecology's existing revolving credit facility. The Term Loan is anticipated to bear interest at a base rate plus 1.25% or LIBOR plus 2.25% (with a step-up to base rate plus 1.50% or LIBOR plus 2.50% in the event US Ecology does not have a BB (with a stable or better outlook) or better from S&P and Ba2 (with a stable or better outlook) or better from Moody's), at US Ecology's option. Interest only payments are due either quarterly or on the last day of any interest period (or, if such interest period extends over three months, at the end of each three month interval during such interest period), as applicable. The Term Loan is subject to amortization in equal quarterly installments in an aggregate annual amount equal to 1.00% of the original principal amount of the Term Loan with the remainder due at maturity. The debt financing is expected to close simultaneously with the closing of the transactions contemplated under the Merger Agreement.

Basis of Pro Forma Presentation

        The unaudited pro forma condensed combined financial statements use the historical financial statements of US Ecology and NRCG, which are prepared in accordance with GAAP, and include pro forma adjustments to present the pro forma financial position and results of operations of the combined company pursuant to the rules and regulations of Article 11 of Regulation S-X of the SEC. The historical financial statements of US Ecology and NRCG have only been adjusted to show pro forma effects that are (i) directly attributable to the Mergers, (ii) factually supportable, and (iii) with respect to the statements of operations, expected to have a continuing impact on the combined company's results.

        The unaudited pro forma condensed combined balance sheet as of June 30, 2019, combines the historical consolidated balance sheets of US Ecology and NRCG, giving effect to the Mergers as if they had occurred on June 30, 2019. The unaudited pro forma condensed combined statements of operations for the six months ended June 30, 2019 and for the year ended December 31, 2018 combine the historical consolidated statements of operations of US Ecology and NRCG, giving effect to the Mergers as if they had occurred on January 1, 2018, the first day of the fiscal year ended December 31, 2018. Based on the terms of the Mergers, US Ecology's management has concluded that US Ecology is the acquiring company for accounting purposes and the Mergers will be accounted for as a business combination in accordance with GAAP. Accordingly, the assets and liabilities of US Ecology will be reported as of the Effective Time of the Mergers at their respective historical carrying values and the acquired net assets of NRCG will be recorded as of the Effective Time of the Mergers at their fair values. For the purpose of these unaudited pro forma condensed combined financial statements, management of US Ecology has determined a preliminary estimated purchase price for the business combination, and such amount has been calculated as described in Note 2 to these unaudited pro forma condensed combined financial statements. The net assets acquired in connection with the

171


Table of Contents

Mergers are at their estimated fair values. A final determination of these estimated fair values will be based on the actual net acquired assets of NRCG as of the Effective Time of the Mergers.

        The unaudited pro forma condensed combined financial information has been compiled in a manner consistent with the accounting policies adopted by US Ecology as disclosed in US Ecology's audited consolidated financial statements as of and for the year ended December 31, 2018 and US Ecology's unaudited condensed consolidated financial statements as of and for the six months ended June 30, 2019.

        NRCG is an "emerging growth company" as defined in the JOBS Act. Section 107 of the JOBS Act provides that an emerging growth company can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards. An emerging growth company can therefore delay the adoption of certain accounting standards until those standards would otherwise apply to private companies, which is generally one year later than public companies.

        US Ecology's net sales presented in the unaudited pro forma condensed combined statement of operations for the six months ended June 30, 2019 and for the year ended December 31, 2018 have been accounted for under the provisions of ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). Due to its emerging growth company status, Topic 606 will be effective for NRCG's fiscal year 2019 and interim periods thereafter. NRCG's management has completed its preliminary assessment of the financial statement impact of Topic 606 and does not expect it to have a material impact on its financial position or results of operations. Accordingly, no adjustment to NRCG's net sales in the unaudited pro forma condensed combined statement of income for the six months ended June 30, 2019 and for the year ended December 31, 2018 has been made.

        US Ecology's operating and financing lease liabilities and corresponding right-of-use assets presented in the unaudited pro forma condensed combined balance sheet as of June 30, 2019 have been accounted for under the provisions of ASU No. 2016-02, Leases (Topic 842), as amended. Due to its emerging growth company status, Topic 842 will be effective for NRCG's annual and interim periods beginning after December 15, 2019. NRCG's management has completed its preliminary assessment of the financial statement impact of Topic 842, resulting in the pro forma recognition of operating and financing lease liabilities and corresponding right-of-use assets of $35.1 million as of June 30, 2019.

        After taking into account NRCG's pro forma adoption of Topic 606 and Topic 842, as well as reclassifications set forth in Note 4, a preliminary analysis indicates that US Ecology's remaining accounting policies are similar in all material respects to those of NRCG. Upon completion of the acquisition, or as more information becomes available, US Ecology will perform a more detailed review of NRCG's accounting policies. As a result of that review, differences could be identified between the accounting policies of the two companies that, when conformed, could have a material impact on the combined financial information.

        Certain reclassifications have been reflected in the pro forma adjustments to conform NRCG's presentation to US Ecology's in the unaudited pro forma condensed combined balance sheet and statements of operations. Note 4 sets forth additional information about reclassifications and adjustments necessary to conform NRCG's financial statements to the accounting policies and presentation used by US Ecology.

NOTE 2. CALCULATION OF ESTIMATED MERGER CONSIDERATION AND PRELIMINARY PURCHASE PRICE ALLOCATION

        The fair value of the merger consideration to be transferred upon completion of the Mergers will include (1) the fair value of Holdco Common Stock to be issued to NRCG stockholders, (2) the fair value of NRCG Warrants that will be exchanged for Replacement Warrants, (3) the fair value attributable to the precombination service period of NRCG replacement RSUs that will be exchanged

172

for replacement Holdco RSUs (4) the fair value of NRCG stock options that will be exchanged for replacement Holdco stock options and (5) Holdco's repayment of NRCG's interest bearing debt, as provided for in the Merger Agreement and in connection with the consummation of the Mergers. The estimated merger consideration is as follows:

Table of Contents

(2)
The estimated fair value of Holdco Common Stock of $59.13 per share as of August 28, 2019, is based on the closing price of ECOL Common Stock on August 28, 2019.

(3)
The estimated fair value of Replacement Warrants of $10.20 per share as of August 28, 2019, was based on the closing price of NRCG Warrants (NYSE: NRCG.WS) of $2.00 on August 28, 2019 divided by the exchange ratio of 0.196.

(4)
The estimated fair value of Holdco replacement RSUs of $59.13 per share as of August 28, 2019, is based on the closing price of ECOL Common Stock on August 28, 2019.

(5)
The estimated fair value of the assumed vested replacement stock options of $9.91 per option as of August 28, 2019 was calculated under the Black-Scholes option pricing model, with the following weighted-average assumptions: strike price of $52.30 per option based on original strike price of $10.25 per option divided by the exchange ratio of 0.196, dividend yield of 1.2%; expected volatility of 30%; average risk-free interest rate of 1.42%; and an expected term of 5.4 years.

        The actual number of shares of Holdco Common Stock issued to NRCG stockholders upon the completion of the Mergers will be based on the actual number of shares of NRCG Common Stock issued and outstanding at the Effective Time of the Mergers, and the valuation of those shares will be based on the per share price of Holdco Common Stock at that time. Likewise, the number of NRCG Warrants, NRCG stock options and NRCG RSUs that will be converted into Replacement Warrants, Holdco stock options and Holdco RSUs upon completion of the Mergers will be based on the actual number of awards that are outstanding at the Effective Time of the Mergers, and the valuation of these awards will also utilize the estimated per share price of Holdco Common Stock at that time. Accordingly, the total purchase price for the Mergers could differ from the amount in the unaudited pro forma condensed combined financial statements, and that difference could be material. A 10% increase (decrease) to the Holdco Common Stock price would increase (decrease) the purchase price by $55.3 million, with a corresponding change to goodwill. Therefore, the estimated consideration expected to be transferred reflected in these unaudited pro forma condensed combined financial statements does not purport to represent what the actual consideration transferred will be when the Mergers are completed.

        Under the acquisition method of accounting, the total purchase price and the acquired tangible and intangible assets and assumed liabilities of NRCG are recorded based on their estimated fair values as of the Effective Time of the Mergers. The excess of the consideration paid over the estimated fair values of net assets acquired will be recorded as goodwill on the unaudited condensed combined consolidated balance sheet.

The final total accounting consideration and amounts allocated to NRCG's assets and liabilities could differ materially from the preliminary amounts presented in these unaudited pro forma condensed combined financial statements. Accounting consideration could decrease based on the market price of Holdco Common Stock which would have a corresponding decrease in the amount of goodwill that would result from the Mergers. A decrease in the fair value of NRCG's assets or an increase in the fair value of NRCG's liabilities from the preliminary valuations presented would result in a dollar-for-dollar corresponding increase in the amount of goodwill that will result from the Mergers.

        Depreciation related to the property and equipment assets is reflected as a pro forma adjustment in the unaudited pro forma condensed combined statements of operations based on the estimated useful lives above and as further described in Note 4(e). The property and equipment assets and related deprecation are preliminary and are based on preliminary valuations prepared by third-party advisors and reviewed by management. If the value of the property and equipment assets is higher than the amounts included in these unaudited pro forma condensed combined financial statements, it may result in higher depreciation expense than is presented in the unaudited pro forma condensed combined statement of operations. Any such increases could be material, and could result in Holdco's actual future financial condition and results of operations differing materially from those presented in the unaudited pro forma condensed combined financial statements.

        Identified intangible assets are required to be measured at fair value and these acquired assets could include assets that are not intended to be used or sold or that are intended to be used in a manner other than their highest and best use. For purposes of these unaudited pro forma condensed combined financial statements, US Ecology assumed that all assets will be used in a manner that represents the highest and best use of those assets. Preliminary identified intangible assets in the unaudited pro forma condensed combined financial information consist of the following:

The preliminary fair value of noncontractual customer relationships was estimated under an income approach using the "multi-period excess earnings" method which considers the net cash flows expected to be generated by the intangible asset by excluding any cash flows related to contributory assets. The incremental after-tax cash flows attributable to

Table of Contents

(2)
The preliminary fair value of contractual customer relationships was estimated under an income approach using the "lost profits" method which considers the loss of economic profits under a hypothetical condition where the intangible asset does not exist and needs to be re-created. Cash flows are calculated both including and excluding the intangible asset and the difference in cash flows is discounted to a present value. Significant assumptions used to estimate the preliminary fair value of contractual customer relationships under this method include the estimated financial performance without the contractual customer relationships in place, the estimated time needed to re-create the contractual customer relationships, the estimated customer attrition rate and the concluded discount rate.

(3)
The preliminary fair value of amortizing permits and licenses was estimated under a cost approach which considers the cost to acquire a similar or substitute asset of equivalent utility. Significant assumptions used to estimate the preliminary fair value of amortizing permits and licenses under this method include the labor costs, advisory fees, and other expenses estimated to be incurred to obtain the permits and licenses.

(4)
The preliminary fair value of tradenames was estimated under a combination of an income approach and a market approach using the "relief-from-royalty" method which considers the market-based royalty a company would pay to enjoy the benefits of the tradename in lieu of actual ownership of the tradename. The hypothetical stream of royalty payments is then discounted to a present value. Significant assumptions used to estimate the preliminary fair value of tradenames under this method include the estimated royalty rate and the concluded discount rate.

(5)
The preliminary fair value of nonamortizing permits and licenses was estimated under the "multi-period excess earnings" method as previously discussed. Significant assumptions used to estimate the preliminary fair value of nonamortizing permits and licenses under this method include the estimated contributory asset charges and the concluded discount rate.

        Amortization related to the identified intangible assets is reflected as a pro forma adjustment in the unaudited pro forma condensed combined statements of operations based on the estimated useful lives above and as further described in Note 4(d). The identified intangible assets and related amortization are preliminary and are based on preliminary valuations prepared by third-party advisors and reviewed by management. As discussed above, the amount that will ultimately be allocated to identified intangible assets and the related amount of amortization, may differ materially from this preliminary allocation. In addition, the amortization impacts will ultimately be based upon the periods in which the associated economic benefits or detriments are expected to be derived. Therefore, the amount of amortization following the Mergers may differ significantly between periods based upon the final value assigned and amortization methodology used for each identified intangible asset.

        Subject to the rights, if any, of the holders of any series of Holdco preferred stock if and when issued and subject to applicable law, each holder of Holdco Common Stock will be entitled to one vote per share on any matter to be voted upon by Holdco stockholders; provided, however, that holders of shares of Holdco Common Stock will have cumulative voting in connection with the election of directors, which means that holders will be entitled to as many votes as shall equal the number of votes which (except for this provision on cumulative voting) such holder would be entitled to cast for the election of directors with respect to such holder's shares of stock multiplied by the number of directors to be elected by such holder, and such holder may cast all of such votes for a single director or may distribute them among the number to be voted for, or for any two or more of them as such holder may see fit.

Dividends

        Subject to the rights, if any, of holders of any series of outstanding Holdco preferred stock, if and when issued and subject to applicable law, holders of Holdco Common Stock will be entitled to receive dividends when, as and if declared by the Holdco Board out of funds legally available for payment.

Liquidation Rights

        Subject to the rights, if any, of holders of any series of outstanding Holdco preferred stock, if and when issued and subject to applicable law, in the event of any liquidation, dissolution or winding up of the affairs of Holdco, whether voluntary or involuntary, the holders of shares of Holdco Common Stock will be entitled to share ratably in all assets remaining after the payment of creditors.

Preemptive Rights

        The shares of Holdco Common Stock to be issued at the Effective Time will be validly issued, fully paid and non-assessable. Holders of Holdco Common Stock will not have preemptive, conversion, redemption or sinking fund rights.

Nasdaq Listing

        After giving effect to the Holdco Amended Charter and the transactions contemplated by the Merger Agreement, Holdco will change its name to "US Ecology, Inc." and Holdco Common Stock will be listed on Nasdaq under the symbol "ECOL." In addition, the parties to the Merger Agreement intend for Holdco to list the Replacement Warrants on Nasdaq under the symbol "ECOLW" in connection with the closing of the Mergers.

Holdco Preferred Stock

General

        Under the Holdco Amended Charter, the Holdco Board will be authorized to issue up to 1,000,000 shares of Holdco preferred stock, par value $0.01 per share. Holdco will also be able to issue, from time to time in one or more series, the terms of which may be determined at the time of issuance by the Holdco Board, without further action by Holdco stockholders, shares of Holdco preferred stock and such shares may include voting rights, preferences as to dividends, liquidation and conversion rights, redemption rights and sinking fund provisions. The shares of each series of Holdco preferred stock will have preferences, limitations and relative rights, including voting rights, identical with those of other shares of the same series and, except to the extent provided in the description of such series, of those of other series of Holdco preferred stock.

        After giving effect to the Holdco Amended Charter, the issuance of any Holdco preferred stock could adversely affect the rights of the holders of Holdco Common Stock and, therefore, reduce the value of the Holdco Common Stock. If and when the Holdco Amended Charter becomes effective, the ability of the Holdco Board to issue Holdco preferred stock could discourage, delay or prevent a takeover or change in control.

Other

        If and when the Holdco Amended Charter becomes effective, Holdco's issuance of Holdco preferred stock could decrease the amount of earnings and assets available for distribution to the holders of Holdco Common Stock or could adversely affect the rights and powers, including voting rights, of the holders of Holdco Common Stock. The issuance of Holdco preferred stock could have the effect of decreasing the market price of Holdco Common Stock.

Restrictions on Holdco Stock Ownership and Purchase of Capital Stock by Non-U.S. Citizens Under the Holdco Amended Charter

        Certain of NRCG's operations are, and following the Mergers, certain of Holdco's operations will be, conducted in the U.S. coastwise trade and are governed by the Jones Act, which is principally contained in 46 U.S.C. Chapters 121, 505 and 551 and the related regulations. The Jones Act restricts the transportation of merchandise and passengers for hire by water or by land and water, either directly or via a foreign port between points in the United States and certain of its island territories and possessions, to U.S.-flag vessels that meet certain requirements, including that they are built in the United States, owned and controlled by U.S. Citizens (within the meaning of the Jones Act), and manned by predominantly U.S. Citizen crews. Should Holdco fail to satisfy the requirements of the Jones Act to be a U.S. Citizen after the consummation of the Mergers, Holdco would be prohibited from operating its vessels in the U.S. coastwise trade during the period of such non-compliance. In addition, Holdco could be subject to substantial fines and Holdco's vessels could be subject to seizure and forfeiture for violations of the Jones Act.

Table of Contents

        The following is a summary of the restrictions (the "Maritime Restrictions") in Article Eighth of the Holdco Amended Charter. This summary is qualified in its entirety by reference to the full text of the Holdco Amended Charter.

General Restriction on Ownership of Shares by non-U.S. Citizens

        In order to protect Holdco's eligibility as a U.S. Citizen, the Holdco Amended Charter restricts the record or beneficial ownership or control of shares of each class or series of Holdco's capital stock, which includes Holdco Common Stock, by non-U.S. Citizens to no more than 24% in the aggregate of the total issued and outstanding shares of such class or series. Holdco refers to such percentage restriction on ownership by non-U.S. Citizens of any class or series of shares of Holdco's capital stock as the "Permitted Percentage" and any such shares owned by non-U.S. Citizens in excess of the Permitted Percentage as "Excess Shares." The Holdco Amended Charter provides that a person will not be deemed to be the beneficial owner of shares of Holdco's capital stock, if the Holdco Board determines that such person is not the beneficial owner of such shares for the purposes of the Jones Act. All references to beneficial ownership of shares and the derivative phrases thereof in this summary of the Maritime Restrictions include record ownership of shares and the ability to control shares.

Restriction on Transfers of Excess Shares

        The Maritime Restrictions provide that no shares of any class or series of the capital stock of Holdco may be transferred to a non-U.S. Citizen or a holder of record that will hold such shares for or on behalf of a non-U.S. Citizen if, upon completion of such transfer, the number of shares of such class or series beneficially owned by all non-U.S. Citizens in the aggregate would exceed the Permitted Percentage for such class or series. Any transfer or purported transfer of beneficial ownership of any shares of any class or series of capital stock of Holdco, the effect of which would be to cause one or more non-U.S. Citizens in the aggregate to beneficially own shares of any class or series of capital stock of Holdco in excess of the Permitted Percentage for such class or series, shall, to the fullest extent permitted by law, be void ab initio and ineffective, and, to the extent that Holdco or its transfer agent (if any) knows that such transfer or purported transfer would, if completed, be in violation of the restrictions on transfers to non-U.S. Citizens set forth in the Maritime Restrictions, neither Holdco nor its transfer agent (if any) shall register such transfer or purported transfer on the stock transfer records of Holdco and neither Holdco nor its transfer agent (if any) shall recognize the transferee or purported transferee thereof as a stockholder of Holdco for any purpose whatsoever (including for purposes of voting, dividends and other distributions) except to the extent necessary to effect any remedy available to Holdco under the Maritime Restrictions. In no event shall any such registration or recognition make such transfer or purported transfer effective unless the Holdco Board (or any duly authorized committee thereof, or any officer of Holdco who shall have been duly authorized by the Holdco Board or any such committee thereof) shall have expressly and specifically authorized the same.

        In connection with any purported transfer of shares of any class or series of the capital stock of Holdco, any transferee or proposed transferee of shares and, if such transferee or proposed transferee is acting as a fiduciary or nominee for a beneficial owner, such beneficial owner, may be required by Holdco or its transfer agent to deliver (1) certification (which may include as part thereof a form of affidavit) upon which Holdco and its transfer agent shall be entitled to rely conclusively stating whether such transferee or proposed or purported transferee or, if such transferee or proposed transferee is acting as custodian, nominee, purchaser representative or in any other capacity for a beneficial owner, whether such beneficial owner, is a U.S. Citizen, and (2) such other documentation and information concerning its citizenship under the Maritime Restrictions as Holdco may request in its sole discretion. Registration and recognition of any transfer of shares may be denied by Holdco upon refusal to furnish any of the foregoing citizenship certifications, documentation or information requested by Holdco. Each proposed transferor of such shares shall reasonably cooperate with any requests from Holdco to

190


Table of Contents

facilitate the transmission of requests for such citizenship certifications and such other documentation and information to the proposed transferee and such proposed transferee's responses thereto.

        Notwithstanding any of the Maritime Restrictions, Holdco shall be entitled to rely, without limitation, on the stock transfer and other stockholder records of Holdco (and its transfer agent) for the purposes of preparing lists of stockholders entitled to vote at meetings, determining the validity and authority of proxies, and otherwise conducting votes of stockholders.

Excess Shares

        If on any date, including, without limitation, any record date (each, an "Excess Share Date"), the number of shares of any class or series of capital stock of Holdco beneficially owned by all non-U.S. Citizens in the aggregate should exceed the Permitted Percentage with respect to such class or series of capital stock, irrespective of the date on which such event becomes known to Holdco (such shares in excess of the Permitted Percentage, the "Excess Shares"), then the shares of such class or series of capital stock of Holdco that constitute Excess Shares for purposes of the Maritime Restrictions shall be (1) those shares that have been acquired by or become beneficially owned by non-U.S. Citizens, starting with the most recent acquisition of beneficial ownership of such shares by a non-U.S. Citizen and including, in reverse chronological order of acquisition, all other acquisitions of beneficial ownership of such shares by non-U.S. Citizens from and after the acquisition of beneficial ownership of such shares by a non-U.S. Citizen that first caused such Permitted Percentage to be exceeded, or (2) those shares beneficially owned by non-U.S. Citizens that exceed the Permitted Percentage as the result of any repurchase or redemption by Holdco of shares of its capital stock, starting with the most recent acquisition of beneficial ownership of such shares by a non-U.S. Citizen and going in reverse chronological order of acquisition; provided, however, that: (a) Holdco shall have the power to determine, in its sole discretion, those shares of such class or series that constitute Excess Shares in accordance with the provisions of the Maritime Restrictions; (b) Holdco may, in its sole discretion, rely on any documentation provided by non-U.S. Citizens with respect to the date and time of their acquisition of beneficial ownership of Excess Shares; (c) if the acquisition of beneficial ownership of more than one Excess Share occurs on the same date and the time of acquisition is not definitively established, then the order in which such acquisitions shall be deemed to have occurred on such date shall be determined by lot or by such other method as Holdco may, in its sole discretion, deem appropriate; (d) Excess Shares that result from a determination that a beneficial owner has ceased to be a U.S. Citizen shall be deemed to have been acquired, for purposes of the Maritime Restrictions, as of the date that such beneficial owner ceased to be a U.S. Citizen; and (e) Holdco may adjust upward to the nearest whole share the number of shares of such class or series deemed to be Excess Shares. Any determination made by Holdco pursuant to the Maritime Restrictions as to which shares of any class or series of Holdco's capital stock constitute Excess Shares of such class or series shall be conclusive and shall be deemed effective as of the applicable Excess Share Date for such class or series.

Redemption of Excess Shares

        To the extent that the above ownership and transfer restrictions would be ineffective for any reason, the Maritime Restrictions provide that, to prevent the percentage of aggregate shares of any class or series of Holdco's capital stock owned by non-U.S. Citizens from exceeding the Permitted Percentage, Holdco, by action of the Board of Directors (or any duly authorized committee thereof), in its sole discretion, will have the power (but not the obligation) to redeem all or any number of such Excess Shares, unless such redemption is not permitted under applicable law.

        Until such Excess Shares are redeemed or they are no longer Excess Shares, the holders of such shares will not be entitled to any voting rights with respect to such shares and Holdco will pay any dividends or distributions with respect to such shares into a segregated account. Full voting, distribution and dividend rights will be restored to such Excess Shares (and any dividends or distributions paid into

191


Table of Contents

a segregated account will be paid to holders of record of such shares), promptly after the time and to the extent that such shares have ceased to be Excess Shares, unless such shares have already been redeemed by Holdco.

        If the Holdco Board (or any duly authorized committee thereof) determines to redeem Excess Shares, the per share redemption price (the "Redemption Price") for each Excess Share shall be paid by the issuance of one Redemption Warrant (as defined below) for each Excess Share; provided, however, that if (1) Holdco determines that a Redemption Warrant would be treated as capital stock under the Jones Act or (2) Holdco is prevented from legally issuing Redemption Warrants under applicable law, then the Redemption Price shall be paid, as determined by the Holdco Board (or any duly authorized committee thereof) in its sole discretion, (a) in cash (by wire transfer or bank or cashier's check), (b) by the issuance of Redemption Notes (as defined below), (c) by any combination of cash and Redemption Notes, or (d) by any other means authorized or permitted under the DGCL.

        With respect to the portion of the Redemption Price being paid in whole or in part by cash and/or by the issuance of Redemption Notes, such portion of the Redemption Price shall be an amount equal to, in the case of cash, or a principal amount equal to, in the case of Redemption Notes, the sum of (1) the fair market value of such Excess Share as of the date of redemption of such Excess Share plus (2) an amount equal to the amount of any dividend or any other distribution (upon liquidation or otherwise) declared in respect of such Excess Share prior to the date on which such Excess Share is called for redemption and which amount has been paid into a segregated account by Holdco.

        Written notice of the redemption of the Excess Shares containing the information set forth in the Maritime Restrictions, together with a letter of transmittal to accompany certificates, if any, representing the Excess Shares that have been called for redemption, shall be given either by hand delivery or by overnight courier service or by first-class mail, postage prepaid, to each holder of record of the Excess Shares to be redeemed, at such holder's last known address as the same appears on the stock register of Holdco (the "Redemption Notice"), unless such notice is waived in writing by any such holders.

192


Table of Contents

        The date on which the Excess Shares shall be redeemed (the "Redemption Date") shall be the later of (1) the date specified in the Redemption Notice sent to the record holder of the Excess Shares (which shall not be earlier than the date of such notice), and (2) the date on which Holdco has irrevocably deposited in trust with a paying agent or set aside for the benefit of such record holder consideration sufficient to pay the Redemption Price to such record holders of such Excess Shares in Redemption Warrants, cash and/or Redemption Notes.

        Each Redemption Notice to each holder of record of the Excess Shares to be redeemed shall specify (1) the Redemption Date (as determined pursuant to the Maritime Restrictions), (2) the number and the class or series of shares of capital stock to be redeemed from such holder as Excess Shares (and, to the extent such Excess Shares are certificated, the certificate number(s) representing such Excess Shares), (3) the Redemption Price and the manner of payment thereof, (4) the place where certificates for such Excess Shares (if such Excess Shares are certificated) are to be surrendered for cancellation, (5) any instructions as to the endorsement or assignment for transfer of such certificates (if any) and the completion of the accompanying letter of transmittal, and (6) the fact that all right, title and interest in respect of the Excess Shares to be redeemed (including, without limitation, voting, dividend and distribution rights) shall cease and terminate on the Redemption Date, except for the right to receive the Redemption Price, without interest.

        On and after the Redemption Date, all right, title and interest in respect of the Excess Shares selected for redemption (including, without limitation, voting and dividend and distribution rights) shall forthwith cease and terminate, such Excess Shares shall no longer be deemed to be outstanding shares for any purpose, including, without limitation, for purposes of voting or determining the total number of shares entitled to vote on any matter properly brought before the stockholders for a vote thereon or receiving any dividends or distributions (and may be either cancelled or held by Holdco as treasury stock), and the holders of record of such Excess Shares shall thereafter be entitled only to receive the Redemption Price, without interest.

        Upon surrender of the certificates (if any) for any Excess Shares so redeemed in accordance with the requirements of the Redemption Notice and the accompanying letter of transmittal (and otherwise in proper form for transfer as specified in the Redemption Notice), the holder of record of such Excess Shares shall be entitled to payment of the Redemption Price. In case fewer than all the shares represented by any such certificate are redeemed, a new certificate (or certificates), to the extent such shares were certificated, shall be issued representing the shares not redeemed, without cost to the holder of record. On the Redemption Date, to the extent that dividends or other distributions (upon liquidation or otherwise) with respect to the Excess Shares selected for redemption were paid into a segregated account, then, to the fullest extent permitted by applicable law, such amounts shall be released to Holdco upon the completion of such redemption.

        Nothing in the Maritime Restrictions will prevent the recipient of a Redemption Notice from transferring its shares before the Redemption Date if such transfer is otherwise permitted under the Maritime Restrictions and applicable law and the recipient provides notice of such proposed transfer to Holdco along with the documentation and information required under the Maritime Restrictions establishing that such proposed transferee is a U.S. Citizen to the satisfaction of Holdco in its sole discretion before the Redemption Date. If such conditions are met, the Board of Directors (or any duly authorized committee thereof) will withdraw the Redemption Notice related to such shares, but otherwise the redemption thereof will proceed on the Redemption Date in accordance with the Maritime Restrictions and the Redemption Notice.

Permitted Actions by Holdco to Enforce the Maritime Restrictions

        Holdco has the power to determine the citizenship of the beneficial owners and the transferees or proposed transferees (and, if such transferees or proposed transferees are acting as fiduciaries or

193


Table of Contents

nominees for any beneficial owners, the citizenship of such beneficial owners) of any class or series of Holdco's capital stock and to require confirmation from time to time of the citizenship of the beneficial owners of any shares of its capital stock. As a condition to acquiring and having beneficial ownership of any shares of its capital stock, every beneficial owner of Holdco's shares must comply with certain provisions in the Maritime Restrictions concerning citizenship, which are summarized below. Holdco has the right under the Maritime Restrictions to require additional reasonable proof of the citizenship of beneficial owners, transferees or proposed transferees (and any beneficial owners for whom such transferees or proposed transferees are acting as fiduciaries or nominees) of any shares of its capital stock, and the determination of Holdco at any time as to the citizenship of such persons is conclusive.

        The Maritime Restrictions require that promptly upon a beneficial owner's acquisition of beneficial ownership of 5% or more of the outstanding shares of any class or series of capital stock of Holdco, and at such other times as Holdco may determine by written notice to such beneficial owner, such beneficial owner must provide to Holdco a written statement or an affidavit, as specified by Holdco, stating the name and address of such beneficial owner, the number of shares of each class or series of capital stock of Holdco beneficially owned by such beneficial owner as of a recent date, the legal structure of such beneficial owner, a statement as to whether such beneficial owner is a U.S. Citizen, and such other information and documents required by the U.S. Coast Guard or the U.S. Maritime Administration under the Jones Act, including 46 C.F.R. part 355. In addition, under the Maritime Restrictions, a beneficial owner is required to provide such a written statement or affidavit when Holdco determines, in its sole discretion, that the citizenship status of such beneficial owner may have changed or that it is necessary under the Jones Act for Holdco to confirm Holdco's citizenship status.

        Under the Maritime Restrictions, when a beneficial owner of any shares of Holdco's capital stock ceases to be a U.S. Citizen, such beneficial owner is required to provide to Holdco, as promptly as practicable but in no event less than five business days after the date such beneficial owner becomes aware that it is no longer a U.S. Citizen, a written statement, stating the name and address of such beneficial owner, the number of shares of each class or series of its capital stock beneficially owned by such beneficial owner as of a recent date, the legal structure of such beneficial owner, and a statement as to such change in status of such beneficial owner to a non-U.S. Citizen.

        The Maritime Restrictions require that, promptly after becoming a beneficial owner, every beneficial owner must provide, or authorize such beneficial owner's broker, dealer, custodian, depositary, nominee or similar agent with respect to the shares of each class or series of Holdco's capital stock beneficially owned by such beneficial owner to provide, to Holdco such beneficial owner's address. A beneficial owner of Holdco's capital stock is also required by the Maritime Restrictions to provide promptly upon request Holdco with a written statement or an affidavit, as specified by Holdco, stating the name and address of such beneficial owner, together with reasonable documentation of the date and time of such beneficial owner's acquisition of beneficial ownership of the shares of any class or series of capital stock of Holdco specified by Holdco in its request.

        In the event that Holdco requests the documentation described above and a beneficial owner fails to provide it by the specified date, the Maritime Restrictions provide for the suspension of the voting rights of such beneficial owner's shares of Holdco's capital stock and for the payment of dividends and distributions (upon liquidation or otherwise) with respect to those shares into a segregated account until the requested documentation is submitted in form and substance reasonably satisfactory to Holdco (subject to the other Maritime Restrictions). In addition, Holdco, upon approval by the Board of Directors (or any duly authorized committee thereof) in its sole discretion, has the power to treat such beneficial owner as a non-U.S. Citizen unless and until Holdco receives the requested documentation confirming that such beneficial owner is a U.S. Citizen.

        In the event that Holdco requests a transferee or proposed transferee (and, if such transferee or proposed transferee is acting as a fiduciary or nominee for a beneficial owner, such beneficial owner)

194


Table of Contents

of, shares of any class or series of Holdco's capital stock to provide the documentation described above, and such person fails to submit it in form and substance reasonably satisfactory to Holdco by the specified date, Holdco, acting through its Board of Directors (or any duly authorized committee thereof, or any officer of Holdco who shall have been duly authorized by the Board of Directors or any such committee thereof), will have the power, in its sole discretion, to refuse to accept any application to transfer ownership of such shares (if any) or to register such shares on the stock transfer records of Holdco and may prohibit and/or void such transfer, including by placing a stop order with Holdco's transfer agent, until such requested documentation is submitted and Holdco is satisfied that the proposed transfer of shares will not result in Excess Shares.

        Certificates representing shares of any class or series of Holdco's capital stock will bear legends concerning the Maritime Restrictions. Within a reasonable time after the issuance or transfer of uncertificated shares of Holdco's capital stock, Holdco will give notice, in writing or by electronic transmission, of the Maritime Restrictions.

Maritime Restrictions Severable

        The Maritime Restrictions are intended to be severable. If any one or more of the Maritime Restrictions is held to be invalid, illegal or unenforceable, the Holdco Amended Charter provides that the validity, legality or enforceability of any other provision will not be affected.

Summary of Requirements to be a U.S. Citizen

        The following is a summary of the requirements to be a U.S. Citizen within the meaning of the Jones Act. Each holder and potential purchaser of Holdco stock should consult its own counsel as to whether it is a U.S. Citizen or a non-U.S. Citizen before purchasing Holdco stock. The Jones Act specifies that ownership of at least 75% of the equity interest by U.S. Citizens means ownership free from any trust or fiduciary obligations in favor of, or any agreement, arrangement or understanding or other means by which more than 25% of the voting power or control of the corporation may be exercised directly or indirectly by or on behalf of, non-U.S. Citizens. In addition, these citizenship requirements apply at each tier in Holdco's ownership chain, which means that they must be satisfied by each person that contributes to Holdco's eligibility as a U.S. Citizen, and each person that contributes to the eligibility of such other person as a U.S. Citizen at each tier of ownership. For entities of a kind not described below, citizenship requirements may vary.

195


Table of Contents

        If Holdco should fail to comply with the above described ownership requirements, Holdco's vessels could lose their ability to engage in U.S. coastwise trade. To assist Holdco with compliance with these requirements, the Holdco Amended Charter will:

        All potential investors will be required to certify to Holdco if it is a U.S. Citizen before investing in Holdco Common Stock. If you or a proposed transferee cannot or do not make such certification, or a sale of stock to you or a transfer of your stock would result in the ownership by non-U.S. Citizens of 24% or more of Holdco Common Stock, such person may not be allowed to purchase or transfer Holdco Common Stock, or such purchase or transfer may be reversed or the shares so purchased or transferred may be redeemed under the proposed Holdco Amended Charter. All certificates representing the shares of Holdco Common Stock will bear legends referring to the foregoing restrictions. Within a reasonable time after the issuance or transfer of uncertificated shares of Holdco's capital stock, Holdco will give notice, in writing or by electronic transmission, of the Maritime Restrictions.

DESCRIPTION OF HOLDCO REPLACEMENT WARRANTS

        At the closing of the NRCG Merger, Holdco will issue a Replacement Warrant in respect of each outstanding NRCG Warrant that will be exercisable for a number of shares of Holdco Common Stock equal to the product (rounded up to the nearest whole number) of (1) the number of shares of NRCG Common Stock that would have been issuable upon the exercise of the NRCG Warrant immediately prior to the Effective Time and (2) the NRCG Exchange Ratio, at an exercise price equal to the quotient obtained by dividing (a) the pre-NRCG Merger exercise price ($11.50 per share) by (b) the NRCG Exchange Ratio (the "Replacement Warrant Exercise Price"). Each Replacement Warrant will entitle the registered holder thereof to purchase Holdco Common Stock at the Replacement Warrant Exercise Price, subject to adjustment as discussed below, at any time. Replacement Warrants will be exercisable only for a whole number of shares of Holdco Common Stock. No fractional shares will be issued upon exercise of the Replacement Warrants. The Replacement Warrants will expire upon October 17, 2023, or earlier upon redemption or liquidation. The Replacement Warrants are expected to be listed on Nasdaq under the symbol "ECOLW."

        Holdco will not be obligated to deliver any shares of Holdco Common Stock pursuant to the exercise of a Replacement Warrant and will have no obligation to settle a Replacement Warrant exercise unless a registration statement under the Securities Act with respect to the Holdco Common Stock underlying the Replacement Warrants is then effective and a prospectus relating thereto is current, subject to Holdco satisfying its obligations described below with respect to registration. No Replacement Warrant will be exercisable for cash or on a cashless basis, and Holdco will not be obligated to issue any Holdco Common Stock to holders seeking to exercise their Replacement Warrants, unless the issuance of the Holdco Common Stock upon such exercise is registered or qualified under the securities laws of the state of the exercising holder, unless an exemption is available. In the event that the conditions in the two immediately preceding sentences are not satisfied with respect to a Replacement Warrant, the holder of such Replacement Warrant will not be entitled to exercise such Replacement Warrant and such Replacement Warrant may have no value and expire worthless.

        In no event will Holdco be required to issue cash, securities or other compensation in exchange for the Replacement Warrants in the event that Holdco is unable to register or qualify the shares underlying the Replacement Warrants under the Securities Act or applicable state securities laws. If the issuance of the shares upon exercise of the Replacement Warrants is not so registered or qualified, the holder of such Replacement Warrant shall not be entitled to exercise such Replacement Warrant and such Replacement Warrant may have no value and expire worthless. In such event, holders who acquired their Replacement Warrants as part of a purchase of units will have paid the full unit purchase price solely for the shares of Holdco Common Stock included in the units.

        Notwithstanding the above, if Holdco Common Stock is at the time of any exercise of a Replacement Warrant not listed on a national securities exchange such that it satisfies the definition of a "covered security" under Section 18(b)(1) of the Securities Act, Holdco may, at its option, require holders of Replacement Warrants who exercise their Replacement Warrants to do so on a "cashless basis" in accordance with Section 3(a)(9) of the Securities Act and, in the event Holdco so elects, Holdco will not be required to file or maintain in effect a registration statement or register or qualify the shares under blue sky laws.

        Once the Replacement Warrants become exercisable, Holdco may call the Replacement Warrants for redemption:

197


Table of Contents

        If and when the Replacement Warrants become redeemable by Holdco, Holdco may not exercise its redemption right if the issuance of shares of Holdco Common Stock upon exercise of the Replacement Warrants is not exempt from registration or qualification under applicable state blue sky laws or Holdco is unable to effect such registration or qualification. Holdco will use its best efforts to register or qualify such shares of Holdco Common Stock under the blue sky laws of the state of residence in those states in which the Replacement Warrants were offered by Holdco.

        The last of the redemption criteria discussed above was established to prevent a redemption call unless there is at the time of the call a significant premium to the Replacement Warrant exercise price. If the foregoing conditions are satisfied and Holdco issues a notice of redemption of the Replacement Warrants, each Replacement Warrant holder will be entitled to exercise his, her or its Replacement Warrant prior to the scheduled redemption date. However, the price of the Holdco Common Stock may fall below the Redemption Trigger Price as well as the Replacement Warrant Exercise Price.

        If Holdco calls the Replacement Warrants for redemption as described above, Holdco's management will have the option to require any holder that wishes to exercise his, her or its Replacement Warrant to do so on a "cashless basis." In determining whether to require all holders to exercise their Replacement Warrants on a "cashless basis," Holdco's management will consider, among other factors, Holdco's cash position, the number of Replacement Warrants that are outstanding and the dilutive effect on Holdco's stockholders of issuing the maximum number of shares of Holdco Common Stock issuable upon the exercise of Holdco's Replacement Warrants. If Holdco's management takes advantage of this option, all holders of Replacement Warrants would pay the exercise price by surrendering their Replacement Warrants for that number of shares of Holdco Common Stock equal to the quotient obtained by dividing (1) the product of the number of shares of Holdco Common Stock underlying the Replacement Warrants, multiplied by the difference between the exercise price of the Replacement Warrants and the "fair market value" (defined below) by (2) the fair market value. The "fair market value" shall mean the average reported last sale price of the Holdco Common Stock for the ten trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of Replacement Warrants. If Holdco's management takes advantage of this option, the notice of redemption will contain the information necessary to calculate the number of shares of Holdco Common Stock to be received upon exercise of the Replacement Warrants, including the fair market value in such case. Requiring a cashless exercise in this manner will reduce the number of shares to be issued and thereby lessen the dilutive effect of a Replacement Warrant redemption. Holdco believes this feature is an attractive option to Holdco if Holdco does not need the cash from the exercise of the Replacement Warrants.

        A holder of a Replacement Warrant may notify Holdco in writing in the event it elects to be subject to a requirement that such holder will not have the right to exercise such Replacement Warrant, to the extent that after giving effect to such exercise, such person (together with such person's affiliates), to the Replacement Warrant agent's actual knowledge, would beneficially own in excess of 4.9% or 9.8% (or such other amount as a holder may specify) of the shares of Holdco Common Stock outstanding immediately after giving effect to such exercise.

        If the number of outstanding shares of Holdco Common Stock is increased by a stock dividend payable in shares of Holdco Common Stock, or by a split-up of shares of Holdco Common Stock or other similar event, then, on the effective date of such stock dividend, split-up or similar event, the

198


Table of Contents

number of shares of Holdco Common Stock issuable on exercise of each Replacement Warrant will be increased in proportion to such increase in the outstanding shares of Holdco Common Stock. A rights offering to holders of Holdco Common Stock entitling holders to purchase shares of Holdco Common Stock at a price less than the fair market value will be deemed a stock dividend of a number of shares of Holdco Common Stock equal to the product of (1) the number of shares of Holdco Common Stock actually sold in such rights offering (or issuable under any other equity securities sold in such rights offering that are convertible into or exercisable for Holdco Common Stock) multiplied by (2) one minus the quotient of (i) the price per share of Holdco Common Stock paid in such rights offering divided by (ii) the fair market value. For these purposes (1) if the rights offering is for securities convertible into or exercisable for Holdco Common Stock, in determining the price payable for Holdco Common Stock, there will be taken into account any consideration received for such rights, as well as any additional amount payable upon exercise or conversion and (2) fair market value means the volume weighted average price of Holdco Common Stock as reported during the ten trading day period ending on the trading day prior to the first date on which the shares of Holdco Common Stock trade on the applicable exchange or in the applicable market, regular way, without the right to receive such rights.

        In addition, if Holdco, at any time while the Replacement Warrants are outstanding and unexpired, pays a dividend or makes a distribution in cash, securities or other assets to the holders of Holdco Common Stock on account of such shares of Holdco Common Stock (or other shares of Holdco capital stock into which the Replacement Warrants are convertible), other than (1) as described above or (2) certain ordinary cash dividends then the Replacement Warrant exercise price will be decreased, effective immediately after the effective date of such event, by the amount of cash and/or the fair market value of any securities or other assets paid on each share of Holdco Common Stock in respect of such event.

        If the number of outstanding shares of Holdco Common Stock is decreased by a consolidation, combination, reverse stock split or reclassification of shares of Holdco Common Stock or other similar event, then, on the effective date of such consolidation, combination, reverse stock split, reclassification or similar event, the number of shares of Holdco Common Stock issuable on exercise of each Replacement Warrant will be decreased in proportion to such decrease in outstanding shares of Holdco Common Stock.

        Whenever the number of shares of Holdco Common Stock purchasable upon the exercise of the Replacement Warrants is adjusted, as described above, the Replacement Warrant exercise price will be adjusted by multiplying the Replacement Warrant exercise price immediately prior to such adjustment by a fraction (1) the numerator of which will be the number of shares of Holdco Common Stock purchasable upon the exercise of the Replacement Warrants immediately prior to such adjustment, and (2) the denominator of which will be the number of shares of Holdco Common Stock so purchasable immediately thereafter.

        In case of any reclassification or reorganization of the outstanding shares of Holdco Common Stock (other than those described above or that solely affects the par value of such shares of Holdco Common Stock), or in the case of any merger or consolidation of Holdco with or into another corporation (other than a consolidation or merger in which Holdco is the continuing corporation and that does not result in any reclassification or reorganization of Holdco's outstanding shares of Holdco Common Stock), or in the case of any sale or conveyance to another corporation or entity of the assets or other property of Holdco as an entirety or substantially as an entirety in connection with which Holdco is dissolved, the holders of the Replacement Warrants will thereafter have the right to purchase and receive, upon the basis and upon the terms and conditions specified in the Replacement Warrants and in lieu of the shares of Holdco Common Stock immediately theretofore purchasable and receivable upon the exercise of the rights represented thereby, the kind and amount of shares of stock or other securities or property (including cash) receivable upon such reclassification, reorganization, merger or

199

consolidation, or upon a dissolution following any such sale or transfer, that the holder of the Replacement Warrants would have received if such holder had exercised their Replacement Warrants immediately prior to such event. However, if such holders were entitled to exercise a right of election as to the kind or amount of securities, cash or other assets receivable upon such consolidation or merger, then the kind and amount of securities, cash or other assets for which each Replacement Warrant will become exercisable will be deemed to be the weighted average of the kind and amount received per share by such holders in such consolidation or merger that affirmatively make such election, and if a tender, exchange or redemption offer has been made to and accepted by such holders (other than a tender, exchange or redemption offer made by Holdco in connection with redemption rights held by stockholders as provided for in the charter) under circumstances in which, upon completion of such tender or exchange offer, the maker thereof, together with members of any group (within the meaning of Rule 13d-5(b)(1) under the Exchange Act) of which such maker is a part, and together with any affiliate or associate of such maker (within the meaning of Rule 12b-2 under the Exchange Act) and any members of any such group of which any such affiliate or associate is a part, own beneficially (within the meaning of Rule 13d-3 under the Exchange Act) more than 50% of the outstanding shares of Holdco Common Stock, the holder of a Replacement Warrant will be entitled to receive the highest amount of cash, securities or other property to which such holder would actually have been entitled as a stockholder if such Replacement Warrant holder had exercised the Replacement Warrant prior to the expiration of such tender or exchange offer, accepted such offer and all of the Holdco Common Stock held by such holder had been purchased pursuant to such tender or exchange offer, subject to adjustments (from and after the consummation of such tender or exchange offer) as nearly equivalent as possible to the adjustments provided for in the warrant agreement, to be dated as of the closing date of the Mergers, between Holdco and the warrant agent, with respect to the Replacement Warrants (the "Replacement Warrant Agreement"). Additionally, if less than 70% of the consideration receivable by the holders of Holdco Common Stock in such a transaction is payable in the form of Holdco Common Stock in the successor entity that is listed for trading on a national securities exchange or is quoted in an established over-the-counter market, or is to be so listed for trading or quoted immediately following such event, and if the registered holder of the Replacement Warrant properly exercises the Replacement Warrant within 30 days following public disclosure of such transaction, the Replacement Warrant exercise price will be reduced based on the per share consideration minus the Black-Scholes warrant value of the Replacement Warrant in order to determine and realize the option value component of the Replacement Warrant. This formula is to compensate the Replacement Warrant holder for the loss of the option value portion of the Replacement Warrant due to the requirement that the Replacement Warrant holder exercise the Replacement Warrant within 30 days of the event. The Black-Scholes model is an accepted pricing model for estimating fair market value where no quoted market price for an instrument is available.

        The Replacement Warrants are expected to be issued in registered form under the Replacement Warrant Agreement. The Replacement Warrant Agreement will provide that the terms of the Replacement Warrants may be amended without the consent of any holder to cure any ambiguity or correct any defective provision, but will require the approval by the holders of at least 65% of the then outstanding Replacement Warrants to make any change that adversely affects the interests of the registered holders of Replacement Warrants.

        The Replacement Warrants will be exercisable upon surrender of the Replacement Warrant certificate on or prior to the expiration date at the offices of the Replacement Warrant agent, with the exercise form on the reverse side of the Replacement Warrant certificate completed and executed as indicated, accompanied by full payment of the exercise price (or on a cashless basis, if applicable), by certified or official bank check payable to Holdco, for the number of Replacement Warrants being exercised. The Replacement Warrant holders do not have the rights or privileges of holders of Holdco Common Stock and any voting rights until they exercise their Replacement Warrants and receive shares of Holdco Common Stock. After the issuance of shares of Holdco Common Stock upon exercise of the

200


Table of Contents

Replacement Warrants, each holder will be entitled to one vote for each share held of record on all matters to be voted on by stockholders.

        No fractional shares will be issued upon exercise of the Replacement Warrants. If, upon exercise of the Replacement Warrants, a holder would be entitled to receive a fractional interest in a share, Holdco will, upon exercise, round down to the nearest whole number of shares of Holdco Common Stock to be issued to the Replacement Warrant holder.

        In order to protect Holdco's eligibility as a U.S. Citizen in case that ownership of Holdco Common Stock by non-U.S. Citizens exceeds the maximum percentage permitted by the Jones Act (presently 25%), the Holdco Amended Charter and the Holdco Amended Bylaws will contain provisions that limit the maximum aggregate percentage of ownership by non-U.S. Citizens of the Holdco Common Stock to 24% of the outstanding shares of Holdco Common Stock. At and during such time that the 24% maximum permitted percentage of ownership by Non-U.S. Citizens is reached with respect to shares of Holdco Common Stock, Holdco will be unable to permit the exercise of any Replacement Warrants by non-U.S. Citizens. If a holder of the Replacement Warrants that is a non-U.S. Citizen is unable to exercise such Replacement Warrants, it may have to wait to exercise such Replacement Warrants until such time that the 24% maximum permitted percentage of ownership by Non-U.S. Citizens is not reached with respect to shares of Holdco Common Stock or may have to sell such Replacement Warrants to a U.S. Citizen who is able to exercise the Replacement Warrants.

COMPARISON OF RIGHTS OF US ECOLOGY STOCKHOLDERS, NRCG STOCKHOLDERS AND HOLDCO STOCKHOLDERS

        US Ecology, NRCG and Holdco are incorporated under the laws of the State of Delaware and, accordingly, the rights of the US Ecology stockholders, NRCG stockholders and Holdco stockholders are currently governed by the DGCL. Upon completion of the Mergers, Holdco will continue to be a Delaware corporation and will continue to be governed by the DGCL.

        Upon completion of the Mergers, US Ecology stockholders and NRCG stockholders will become Holdco stockholders, and the current certificate of incorporation of Holdco will be amended and restated as of the Effective Time in substantially the form of the Holdco Amended Charter attached as Annex E to this joint proxy statement/prospectus. The current bylaws of Holdco will be amended and restated at the Effective Time in substantially the form of the Holdco Amended Bylaws attached as Annex F to this joint proxy statement/prospectus. Following the Mergers, the rights of the former US Ecology stockholders and the former NRCG stockholders will thereafter be governed by the DGCL and by the Holdco Amended Charter and the Holdco Amended Bylaws.

        The following description summarizes some of the expected material differences among the rights of the US Ecology stockholders, NRCG stockholders and Holdco stockholders, but is not a complete summary of all those material differences, or a complete description of the specific provisions referred to in this summary. Furthermore, the identification of some of the differences in the rights as material is not intended to indicate that other differences do not exist. Stockholders should read carefully the relevant provisions of the DGCL and the certificates of incorporation and bylaws of US Ecology, NRCG and Holdco.

        Pursuant to Section 262, holders of shares of NRCG Series A Preferred Stock who do not wish to accept the merger consideration in respect of such shares of NRCG Series A Preferred Stock pursuant to the Merger Agreement may elect to have the "fair value" of their shares of NRCG Series A Preferred Stock (exclusive of any element of value arising from the accomplishment or expectation of the merger) judicially determined and paid in cash, together with interest, if any, to be paid upon the amount determined to be the fair value, in lieu of receiving the applicable merger consideration. A holder of shares of NRCG Series A Preferred Stock may exercise these appraisal rights only by complying strictly with Section 262. Failure to follow precisely any of the statutory procedures may result in a termination or waiver of appraisal rights.

        The following is a brief summary of the statutory procedures to be followed by holders of NRCG Series A Preferred Stock in order to perfect appraisal rights under Section 262. This summary is not intended to be complete, and is qualified in its entirety by reference to Section 262, the full text of which is included as Annex J to this joint proxy statement/prospectus.

        Any holder of NRCG Series A Preferred Stock seeking to demand appraisal of its shares of NRCG Series A Preferred Stock, or wishing to preserve its right to do so, should review carefully Section 262 and is urged to consult a legal advisor.

        All references in this summary to a "stockholder" are to the record holder of shares of NRCG Series A Preferred Stock unless otherwise indicated. A person having a beneficial interest in shares of NRCG Series A Preferred Stock held of record in the name of another person, such as a bank, broker or other nominee, must act promptly to cause the record holder to follow properly the steps summarized below and in a timely manner to perfect appraisal rights.

        Under Section 262, if a proposed merger is to be submitted for approval at a meeting of stockholders, as in the case of NRCG Special Meeting, a constituent corporation must, not less than 20 days prior to the meeting, notify each of its stockholders entitled to appraisal rights that appraisal rights are available and include in the notice a copy of Section 262. This joint proxy statement/prospectus constitutes such notice to holders of NRCG Series A Preferred Stock, and a copy of Section 262, as in effect with respect to the NRCG Merger, is included as Annex J to this joint proxy statement/prospectus.

        A stockholder wishing to exercise appraisal rights under Section 262 must:

211


Table of Contents

All demands for appraisal should be delivered to:

NRC Group Holdings Corp.
952 Echo Lane, Suite 460
Houston, Texas
Attn: General Counsel

        A demand for appraisal must be executed by or for the stockholder of record and must reasonably inform NRCG of the identity of the stockholder of record and that such stockholder intends thereby to demand appraisal of his, her or its shares of NRCG Series A Preferred Stock. If the shares of NRCG Series A Preferred Stock are owned of record by a person in a fiduciary capacity, such as a trustee, guardian or custodian, the demand should be executed in that capacity. If the shares are owned of record by more than one person, as in a joint tenancy or tenancy in common, the demand should be executed by or on behalf of all of the owners. An authorized agent, including an agent for two or more joint owners, may execute a demand for appraisal on behalf of a stockholder; however, the agent must identify the record owner or owners and expressly disclose the fact that, in executing the demand, the agent is acting as agent for such owner or owners. A record owner, such as a bank or broker, who holds shares as nominee for several beneficial owners may exercise appraisal rights with respect to the shares held for one or more beneficial owners while not exercising these rights with respect to the shares held for one or more other beneficial owners. In that case, the demand should set forth the number of shares as to which appraisal is sought, and where no number of shares is expressly mentioned, the demand will be presumed to cover all shares held in the name of the record owner.

        A demand for appraisal must be made by the holder of record of NRCG Series A Preferred Stock and cannot be made by the beneficial owner. Stockholders who hold their shares of NRCG Series A Preferred Stock in brokerage accounts or other nominee forms and who wish to exercise appraisal rights are urged to consult with their brokers or other nominees to determine appropriate procedures for making a demand for appraisal.

        Within ten days after the date upon which the NRCG Merger becomes effective, the surviving corporation in the NRCG Merger must give written notice of the date that the NRCG Merger has become effective to each stockholder who has complied with Section 262.

        Within 120 days after the date upon which the NRCG Merger becomes effective, the surviving corporation in the NRCG Merger, or any stockholder who has complied with Section 262 and who is otherwise entitled to appraisal rights, may file a petition in the Delaware Court of Chancery (the "Court of Chancery") demanding a determination of the value of the shares of NRCG Series A Preferred Stock held by all the dissenting stockholders that have properly demanded appraisal. A person who is the beneficial owner of shares of NRCG Series A Preferred Stock held in a voting trust or by a nominee on behalf of such person may, in such person's own name, file the petition described in the previous sentence. Any dissenting stockholder desiring to file a petition is advised to file on a timely basis. The failure to file a petition timely could nullify any previous written demand for appraisal. The surviving corporation in the NRCG Merger is under no obligation to file any such petition and stockholders seeking to exercise appraisal rights should not assume that such corporation will file such a petition or that such corporation will initiate any negotiations with respect to the fair value of such shares. Stockholders who desire to have their shares appraised should initiate any petitions necessary for the perfection of their appraisal rights within the time periods and in the manner prescribed in Section 262.

        At any time within 60 days after the date upon which the NRCG Merger becomes effective, any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party shall have the right to withdraw such stockholder's demand for appraisal and to accept the merger consideration in respect of such stockholder's shares of NRCG Series A Preferred Stock. Any attempt to withdraw such demand made more than 60 days after the date upon which the NRCG

212


Table of Contents

Merger becomes effective will require the written approval of the surviving corporation in the NRCG Merger and no appraisal proceeding before the Court of Chancery as to any stockholder will be dismissed without the approval of the Court of Chancery, which approval may be conditioned upon any terms the Court of Chancery deems just. If the surviving corporation in the NRCG Merger does not approve a stockholder's request to withdraw a demand for appraisal when its approval is required or if the Court of Chancery does not approve the dismissal of an appraisal proceeding, the stockholder would be entitled to receive only the appraised value determined in any such appraisal proceeding. This value could be higher or lower than, or the same as, the value of the merger consideration to which such stockholder would be entitled to in respect of his, her or its shares of NRCG Series A Preferred Stock in the NRCG Merger.

        Within 120 days after the date upon which the NRCG Merger becomes effective, any stockholder who has complied with Section 262 to that point in time shall be entitled to receive from NRCG, upon written request, a statement setting forth the aggregate number of shares not voted in favor of adopting the Merger Agreement and with respect to which demands for appraisal have been received and the aggregate number of holders of such shares. A person who is the beneficial owner of shares of NRCG Series A Preferred Stock held in a voting trust or by a nominee on behalf of such person may, in such person's own name, request from the surviving corporation in the NRCG Merger the statement described in the previous sentence. Each written statement shall be mailed within ten days after the stockholder's written request for such statement is received by the surviving corporation in the NRCG Merger or within ten days after expiration of the period for delivery of demands for appraisal under Section 262, whichever is later.

        Upon the filing of any such petition by a stockholder, service of a copy thereof shall be made upon the surviving corporation in the NRCG Merger. If a petition for appraisal is duly filed by a stockholder and a copy thereof is delivered to the surviving corporation in the NRCG Merger, such corporation shall, within 20 days after such service, file with the office of the Register in Chancery in which the petition was filed a duly verified list containing the names and addresses of all stockholders who have demanded payment for their shares and with whom agreement as to the value of their shares has not been reached by such corporation. The Court of Chancery is empowered to conduct a hearing on the petition to determine those stockholders who have complied with Section 262 and who have become entitled to appraisal rights. The Court of Chancery may require the stockholders who demanded appraisal of their shares and who hold stock represented by certificates to submit their stock certificates to the Register in Chancery for notation thereon of the pendency of the appraisal proceedings, and if any stockholder fails to comply with such direction, the Court of Chancery may dismiss the proceedings as to such stockholder.

        After determining which stockholders are entitled to an appraisal, the Court of Chancery will appraise the shares of NRCG Series A Preferred Stock, determining their fair value exclusive of any element of value arising from the accomplishment or expectation of the NRCG Merger, together with interest, if any, to be paid upon the amount determined to be the fair value. Unless the Court of Chancery in its discretion determines otherwise for good cause shown, interest from the date upon which the NRCG Merger becomes effective through the date of payment of the judgment shall be compounded quarterly and shall accrue at 5% over the Federal Reserve discount rate (including any surcharge) as established from time to time during the period between the date upon which the NRCG Merger becomes effective and the date of payment of the judgment. In determining fair value, the Court of Chancery is to take into account all relevant factors. The fair value of their shares as determined under Section 262 could be greater than, the same as, or less than the merger consideration that holders of NRCG Series A Preferred Stock would receive in the NRCG Merger. NRCG does not anticipate offering more than the applicable merger consideration to any stockholder exercising appraisal rights and reserves the right to assert, in any appraisal proceeding, that, for purposes of Section 262, the "fair value" of shares of NRCG Series A Preferred Stock is less than the

213


Table of Contents

merger consideration that holders of NRCG Series A Preferred Stock would receive in the NRCG Merger.

        Upon application by the surviving corporation or by any holder of NRCG Series A Preferred Stock entitled to participate in the appraisal proceeding, the Court of Chancery may, in its discretion, proceed to trial upon the appraisal prior to the final determination of the stockholders entitled to an appraisal. Any holder of shares of NRCG Series A Preferred Stock whose name appears on the verified list and who has submitted such stockholder's stock certificates, if any, to the Delaware Register in Chancery, if such is required, may participate fully in all proceedings until it is finally determined that such stockholder is not entitled to appraisal rights.

        The Court of Chancery will direct the payment of the fair value of the shares, together with interest, if any, by the surviving corporation in the NRCG Merger to the stockholders entitled thereto. Payment shall be so made to each such stockholder, in the case of holders of uncertificated stock forthwith, and in the case of holders of shares represented by certificates upon the surrender to the surviving corporation in the NRCG Merger of the certificates representing such stock.

        The costs of the proceedings may be determined by the Court of Chancery and taxed upon the parties as the Court of Chancery deems equitable in the circumstances. However, costs do not include attorneys' or expert witnesses' fees. Upon application of a stockholder, the Court of Chancery may order that all or a portion of the expenses incurred by any stockholder in connection with the appraisal proceeding be charged pro rata against the value of all of the shares entitled to appraisal. These expenses may include, without limitation, reasonable attorneys' fees and the fees and expenses of experts.

        Any stockholder who has demanded appraisal rights will not, from and after the date upon which the NRCG Merger becomes effective, be entitled to vote shares subject to that demand for any purpose or to receive payment of dividends or any other distribution with respect to those shares, other than with respect to payment as of a record date prior to the date upon which the NRCG Merger becomes effective. If no petition for appraisal is filed within 120 days after the date upon which the NRCG Merger becomes effective, or if the stockholder otherwise fails to perfect, successfully withdraws or loses such holder's right to appraisal, then the right of such stockholder to appraisal will cease and such stockholder will be entitled to receive the merger consideration in respect of his, her or its shares of NRCG Series A Preferred Stock pursuant to the Merger Agreement.

        Failure to strictly follow the steps required by Section 262 for perfecting appraisal rights will result in the loss of appraisal rights, in which event holders of NRCG Series A Preferred Stock will be entitled to receive the merger consideration in respect of their shares of NRCG Series A Preferred Stock pursuant to the Merger Agreement. In view of the complexity of the provisions of Section 262, any stockholder considering exercising its appraisal rights under Section 262 is urged to consult his, her or its own legal advisor.

US Ecology Stockholders

        Under Section 262, US Ecology stockholders are not entitled to appraisal rights in connection with the Mergers.


LEGAL MATTERS

        The validity of the securities being offered by this document will be passed upon by Dechert. U.S. federal income tax consequences relating to the Mergers will also be passed upon by Dechert and/or Jones Day.

        With respect to the unaudited interim financial information for the periods ended March 31, 2019 and 2018 and June 30, 2019 and 2018, which is incorporated herein by reference, Deloitte & Touche LLP, an independent registered public accounting firm, have applied limited procedures in accordance with the standards of the Public Company Accounting Oversight Board (United States) for a review of such information.

        Section 2.06.    Appraisal Rights.     Notwithstanding any provision of this Agreement to the contrary, including Section 2.01, shares of Company Series A Preferred Stock issued and outstanding immediately prior to the Effective Time (other than shares of Company Series A Preferred Stock cancelled in accordance with Section 2.01(b)(i)(2)) and held by a holder who is entitled to demand and has properly exercised appraisal rights of such shares in accordance with Section 262 of the DGCL (such shares of Company Series A Preferred Stock being referred to collectively as the "Dissenting Shares" until such time as such holder fails to perfect or otherwise waives, withdraws, or loses such holder's appraisal rights under the DGCL with respect to such shares) shall not be converted into a right to receive the Preferred Merger Consideration, but instead shall be entitled to only such rights as are granted by Section 262 of the DGCL; provided, however, that if, after the Effective Time, such holder fails to perfect, waives, withdraws, or loses such holder's right to appraisal pursuant to Section 262 of the DGCL or if a court of competent jurisdiction shall determine that such holder is not entitled to the relief provided by Section 262 of the DGCL, such shares of Company Series A Preferred Stock shall be treated as if they had been converted as of the Effective Time into the right to receive the Preferred Merger Consideration in accordance with Section 2.01(b)(ii)(2), without interest thereon, upon surrender of such Certificate formerly representing such share or transfer of such Book-Entry Share, as the case may be. The Company shall provide Parent and Holdco prompt written notice of any demands received by the Company for appraisal of shares of Company Series A Preferred Stock, any waiver or withdrawal of any such demand, and any other demand, notice, or instrument delivered to the Company prior to the Effective Time that relates to such demand, and Parent and Holdco shall have the opportunity and right to direct all negotiations and proceedings with respect to such demands. Except with the prior written consent of Parent and Holdco, the Company shall not make any payment with respect to, or settle, or offer to settle, any such demands.


        
Section 2.07.    Adjustments.     Without limiting the other provisions of this Agreement, if at any time during the period between the date of this Agreement and the Effective Time, any change in the outstanding shares of Company Capital Stock or any capital stock of Parent shall occur (specifically excluding the issuance of additional shares of capital stock of the Company or Parent as permitted by this Agreement, including Section 5.02(c)) by reason of any reclassification, recapitalization, stock split (including a reverse stock split), or combination, exchange, readjustment of shares, or similar transaction, or any stock dividend or distribution paid in stock, the Common Merger Consideration, the Preferred Merger Consideration and any other amounts payable pursuant to this Agreement shall be appropriately adjusted to reflect such change; provided, however, that this sentence shall not be construed to permit Parent, Holdco or the Company to take any action with respect to its securities that is prohibited by the terms of this Agreement.


        
Section 2.08.    Withholding Rights.     Each of the Exchange Agent, Parent, Holdco, Rooster Merger Sub, Parent Merger Sub, the Rooster Surviving Corporation and the Parent Surviving Corporation shall be entitled to deduct and withhold from the consideration otherwise payable to any Person pursuant to this Agreement such amounts as may be required to be deducted and withheld with respect to the making of such payment under any Tax Laws. To the extent that amounts are so deducted and withheld by the Exchange Agent, Parent, Holdco, Rooster Merger Sub, Parent Merger Sub, the Rooster Surviving Corporation or the Parent Surviving Corporation, as the case may be, such amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which the Exchange Agent, Parent, Holdco, Rooster Merger Sub, Parent Merger Sub, the Rooster Surviving Corporation or the Parent Surviving Corporation, as the case may be, made such deduction and withholding.


        
Section 2.09.    Lost Certificates.     If any Certificate or Parent Certificate shall have been lost, stolen, or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate or Parent Certificate to be lost, stolen, or destroyed and, if required by Holdco, the posting by such Person of a bond, in such reasonable amount as Holdco may direct, as indemnity against any

A-17

claim that may be made against it with respect to such Certificate, the Exchange Agent will issue, in exchange for such lost, stolen, or destroyed Certificate or Parent Certificate, the Merger Consideration or Parent Merger Consideration, as applicable, to be paid in respect of the shares of Company Common Stock, Company Series A Preferred Stock or Parent Common Stock formerly represented by such Certificate as contemplated under this Article II.

Section 8.10.    Severability.     The provisions of this Agreement shall be deemed severable and if any term or provision of this Agreement is invalid, illegal, or unenforceable in any jurisdiction, such invalidity, illegality, or unenforceability shall not affect any other term or provision of this Agreement or invalidate or render unenforceable such term or provision in any other jurisdiction. Upon such determination that any term or other provision is invalid, illegal, or unenforceable, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the greatest extent possible.

No assignment shall relieve the assigning party of any of its obligations hereunder.


        
Section 8.12.    Remedies.     Except as otherwise provided in this Agreement, any and all remedies expressly conferred upon a party to this Agreement will be cumulative with, and not exclusive of, any other remedy contained in this Agreement, at Law, or in equity. The exercise by a party to this Agreement of any one remedy will not preclude the exercise by it of any other remedy.


        
Section 8.13.    Specific Performance.     The parties hereto agree that the rights of each party to consummate the transactions contemplated by this Agreement, including the Mergers, are special, unique and of extraordinary character and that irreparable damage would occur if any provision of this Agreement are not performed in accordance with the terms hereof or are otherwise breached, and that the parties shall be entitled to an injunction or injunctions to prevent breaches or threatened breaches of this Agreement or to enforce specifically the performance of the terms and provisions hereof in the Court of Chancery of the State of Delaware (or in the event (but only in the event) that such court does not have subject matter jurisdiction over such Legal Action, in the United States District Court for the District of Delaware) without necessity of posting a bond or other form of security. In the event that any action or proceeding should be brought in equity to enforce the provisions of this Agreement, no party shall allege, and each party hereby waives the defense, that there is an adequate remedy at Law.


        
Section 8.14.    Counterparts; Effectiveness.     This Agreement may be executed in any number of counterparts, all of which will be one and the same agreement. This Agreement will become effective when each party to this Agreement shall have received counterparts signed by all of the other parties.

        NOW, THEREFORE, in consideration of the premises and the mutual covenants of the parties hereto, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

        3.
    Piggyback Registrations.     If at any time Company proposes to register under the Securities Act the issuance or sale of any of its securities, whether or not for sale for its own account and other than pursuant to a Demand Registration or Demand Takedown, on a form and in a manner which would permit registration of the Registrable Securities held by the Holders for sale to the public under the Securities Act, the Company shall give written notice of the proposed registration to the Holders not later than five (5) calendar days prior to the filing thereof. Each Holder shall have the right to request that all or any part of its Registrable Securities be included in such registration. Each Holder can make such a request by giving written notice to the Company within two (2) calendar days after the receipt of such notice by the Holders; provided, however, that if the registration is an Underwritten Offering and the managing underwriters of such offering determine that the aggregate amount of securities of the Company which the Company and all Holders propose to include in such registration statement exceeds the maximum amount of securities that may be sold without having a material adverse effect on the success of the offering, including without limitation the selling price and other terms of such offering, the Company shall include in such registration, first, the securities that the Company proposes to sell, second, the Registrable Securities of such Holders, pro rata among all such Holders on the basis of the relative percentage of Registrable Securities owned by all Holders who have requested that securities owned by them be so included (it being further agreed and understood, however, that such underwriters shall have the right to eliminate entirely the participation of the Holders), and third, the comparable securities of any additional holders of the Company's securities, pro rata among all such holders on the basis of the relative percentage of such securities held by each of them. Registrable Securities proposed to be registered and sold pursuant to an Underwritten Offering for the account of any Holder shall be sold to the prospective underwriters selected or approved by the Company and on the terms and subject to the conditions of one or more underwriting agreements negotiated between the Company and the prospective underwriters. Any Holder who holds Registrable Securities being registered in any offering shall have the right to receive a copy of the form of underwriting agreement and shall have an opportunity to hold discussions with the lead underwriter of the terms of such underwriting agreement. The Company may withdraw any registration statement under this Section 3 at any time before it becomes effective, or postpone or terminate the offering of securities, without obligation or liability to any Holder.

In addition, the Company shall:

        Section 2.
    Annual Meetings.     The Annual Meetings of Stockholders shall be held on the third Saturday of May of each year at 10:00 a.m. or at such other date and time as may be designated by the Board of Directors; provided, however, that should said day fall upon a legal holiday, the annual meeting of stockholders shall be held at the same time on the next day thereafter ensuing which is a full business day. At each annual meeting directors shall be elected, and any other proper business may be transacted.


        Section 3.

Business transacted at any special meeting of stockholders shall be limited to the purposes stated in the notice of the meeting.


        Section 4.
    Notice of Meetings.     Written notice of the place, date, and time of all meetings of the stockholders shall be given, not less than ten (10) nor more than sixty (60) days before the date on which the meeting is to be held, to each stockholder entitled to vote at such meeting, except as otherwise provided herein or as required from time to time by the Delaware General Corporation Law or the Certificate of Incorporation.


        Section 5.
    Quorum; Adjournment.     At any meeting of the stockholders, the holders of a majority of all of the shares of the stock entitled to vote at the meeting, present in person or by proxy, shall constitute a quorum for all purposes, unless or except to the extent that the presence of a larger number may be required by law or the Certificate of Incorporation. If a quorum shall fail to attend any meeting, the chairman of the meeting or the holders of a majority of the shares of stock entitled to vote who are present, in person or by proxy, may adjourn the meeting to another place, date, or time without notice other than announcement at the meeting, until a quorum shall be present or represented.

        When a meeting is adjourned to another place, date or time, written notice need not be given of the adjourned meeting if the place, date and time thereof are announced at the meeting at which the

F-4


Table of Contents

adjournment is taken; provided, however, that if the date of any adjourned meeting is more than thirty (30) days after the date for which the meeting was originally noticed, or if a new record date is fixed for the adjourned meeting, written notice of the place, date, and time of the adjourned meeting shall be given in conformity herewith. At any adjourned meeting, any business may be transacted which might have been transacted at the original meeting.


        Section 6.
    Proxies and Voting.     At any meeting of the stockholders, every stockholder entitled to vote may vote in person or by proxy authorized by an instrument in writing filed in accordance with the procedure established for the meeting.

        Each stockholder shall have one vote for every share of stock entitled to vote which is registered in his name on the record date for the meeting, except as otherwise provided herein or required by law or the Certificate of Incorporation.

        All voting, except where otherwise provided herein or required by law or the Certificate of Incorporation, may be by a voice vote; provided, however, that upon demand therefor by a stockholder entitled to vote or such stockholder's proxy, a stock vote shall be taken. Every stock vote shall be taken by ballots, each of which shall state the name of the stockholder or proxy voting and such other information as may be required under the procedure established for the meeting.

        The stock list shall also be kept at the place of the meeting during the whole time thereof and shall be open to the examination of any such stockholder who is present. This list shall presumptively determine the identity of the stockholders entitled to vote at the meeting and the number of shares held by each of them.


        Section 8.
    Actions by Stockholders.     Unless otherwise provided in the Certificate of Incorporation, any action required to be taken at any annual or special meeting of stockholders of the Corporation, or any action which may be taken at any annual or special meeting of such stockholders, may be taken without a meeting, without prior notice and without a vote, if a consent in writing, setting forth the action so taken, shall be signed by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted. Prompt notice of the taking of the corporate action without a meeting by less than unanimous written consent shall be given to those stockholders who have not consented in writing.


        Section 9.
    Record Date.     In order that the Corporation may determine the stockholders entitled to consent to corporate action in writing without a meeting, the Board of Directors may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board of Directors, and which date shall not be more than ten (10) days after the date upon which the resolution fixing the record date is adopted by the Board of Directors. Any stockholder of record seeking to have the stockholders authorize or take corporate action by written consent shall, by written notice to the Secretary, request the Board of Directors to fix a record date. The Board of Directors shall promptly, but in all events within ten (10) days after the date on which such a request is

F-5


Table of Contents

received, adopt a resolution fixing the record date. If no record date has been fixed by the Board of Directors within ten (10) days after the date on which such a request is received, the record date for determining stockholders entitled to consent to corporate action in writing without a meeting, when no prior action by the Board of Directors is required by applicable law, shall be the first date on which a signed written consent setting forth the action taken or proposed to be taken is delivered to the Corporation by delivery to its registered office in the State of Delaware, its principal place of business, or any officer or agent of the Corporation having custody of the book in which proceedings of stockholders meetings are recorded. Delivery shall be by hand or by certified or registered mail, return receipt requested. If no record date has been fixed by the Board of Directors and prior action by the Board of Directors is required by applicable law, the record date for determining stockholders entitled to consent to corporate action in writing without a meeting shall be at the close of business on the date on which the Board of Directors adopts the resolution taking such prior action.

        In the event of the delivery to the Corporation of a written consent or consents purporting to authorize or take corporate action and/or related revocations (each such written consent and related revocation is referred to in this paragraph as a "Consent"), the Secretary of the Corporation shall provide for the safe-keeping of such Consent and shall conduct such reasonable investigation as he deems necessary or appropriate for the purpose of ascertaining the validity of such consent and all matters incident thereto, including, without limitation, whether stockholders having the requisite voting power to authorize or take the action specified in the Consent have given consent; provided, however, that if the corporate action to which the Consent relates is the removal or replacement of one or more members of the Board of Directors, the Secretary of the Corporation shall designate two persons, who shall not be members of the Board of Directors or officers or employees of the Corporation, to serve as Inspectors with respect to such Consent and such Inspectors shall discharge the functions of the Secretary of the Corporation under this paragraph. If after such investigation the Secretary or the Inspectors (as the case may be) shall determine that the Consent is valid, that fact shall be certified on the records of the Corporation for the purpose of recording the proceedings of meetings of the stockholders, and the Consent shall be filed with such records, at which time the Consent shall become effective as stockholder action.

        In conducting the investigation required by this Section 9, the Secretary or the Inspectors (as the case may be) may, but are not required to (i) at the expense of the Company, retain any necessary or appropriate professional advisors, and such other personnel as they may deem necessary or appropriate to assist them and (ii) allow any officers and representatives of the Company, stockholders soliciting consents or revocations, and any other interested parties to propose challenges and pose questions relating to the preliminary results of such investigation following the availability of such preliminary results.

ARTICLE III

BOARD OF DIRECTORS

        Section 1.    Duties and Powers.     The business of the Corporation shall be managed by or under the direction of the Board of Directors which may exercise all such powers of the Corporation and do all such lawful acts and things as are not by law or by the Certificate of Incorporation or by these Bylaws directed or required to be exercised or done by the stockholders.


        Section 2.

If a quorum shall not be present at any meeting of the Board of Directors, the directors present thereat may adjourn the meeting from time to time, without notice other than announcement at the meeting, until a quorum shall be present.

        Section 7.    Actions of Board Without a Meeting.    Unless otherwise provided by the Certificate of Incorporation or these Bylaws, any action required or permitted to be taken at any meeting of the Board of Directors or of any committee thereof may be taken without a meeting if all members of the Board of Directors or committee, as the case may be, consent thereto in writing, and the writing or writings are filed with the minutes of proceedings of the Board of Directors or committee.

        Section 8.    Meetings by Means of Conference Telephone.    Unless otherwise provided by the Certificate of Incorporation or these Bylaws, members of the Board of Directors of the Corporation, or any committee designated by the Board of Directors, may participate in a meeting of the Board of Directors or such committee by means of a conference telephone or similar communications equipment by means of which all persons participating in the meeting can hear each other, and participation in a meeting pursuant to this Section 8 shall constitute presence in person at such meeting.

        Section 1.    Purpose of the Plan.     The purpose of the US Ecology Parent, Inc.

        Section 8.    Change in Control.     Unless otherwise provided in an Award Agreement or an effective employment, consulting, severance or similar agreement with the Company or a Subsidiary, a Change in Control shall not, in and of itself, accelerate the vesting, settlement or exercisability of outstanding Awards. Notwithstanding the foregoing and unless otherwise provided in an Award Agreement or an effective employment, consulting, severance or similar agreement with the Company or a Subsidiary, if (i) the successor corporation (or its parent) does not agree to assume an outstanding Award or does not agree to substitute or replace such Award with an award involving the ordinary shares of such successor corporation (or its parent) on terms and conditions necessary to preserve the rights of the applicable Participant with respect to such Award, (ii) the securities of the Company or the successor corporation will not be publicly traded on a U.S. securities exchange or (iii) the Change in Control is not approved by a majority of the Incumbent Directors immediately prior to such Change in Control, the Committee, in its sole discretion, may take one or more of the following actions with respect to all, some or any such Awards: (a) accelerate the vesting, settlement and, if applicable, exercisability of such Awards such that the Awards are fully vested, settled and, if applicable, exercisable (effective immediately prior to such Change in Control); provided that Awards subject to performance-based vesting conditions shall be paid or settled in full based on the actual level of achievement of the

G-15


Table of Contents

applicable Performance Goals through the date of the Change in Control or, if doing so would result in the Participant's receipt of a larger payment or settlement amount, using the applicable target (or, in the case of a Change in Control described in clause (ii), maximum) level of achievement through the date of such Change in Control rather than such actual level of achievement; (b) cancel outstanding Options or SARs in exchange for a cash payment in an amount equal to the excess, if any, of the Fair Market Value of the Shares underlying the unexercised portion of the Option or SAR as of the date of the Change in Control over the exercise price or grant price, as the case may be, of such portion, provided that any Option or SAR with an exercise price or grant price, as the case may be, that equals or exceeds the Fair Market Value of the Shares on the date of the Change in Control shall be cancelled with no payment due the Participant; or (c) take such other actions as the Committee deems appropriate to preserve the rights of Participants with respect to their Awards. The judgment of the Committee with respect to any matter referred to in this Section shall be conclusive and binding upon each Participant without the need for any amendment to the Plan. Notwithstanding the foregoing, no Award that constitutes "non-qualified deferred compensation" (within the meaning of Section 409A of the Code) shall be payable upon the occurrence of a Change in Control unless such Change in Control satisfies the requirements of Treasury Regulation Section 1.409A-3(i)(5). In addition to the actions described above, and without the consent of any Participant, effective upon the occurrence of a Change in Control, the Committee may, in its sole discretion, terminate all Awards granted under the Plan that are treated as "non-qualified deferred compensation" under Section 409A of the Code and settle such shares for a cash payment equal to the Fair Market Value of such Shares or any benchmark, if any, provided that (1) such Change in Control satisfies the requirements of Treasury Regulation Section 1.409A-3(i)(5) and (2) all other arrangements that would be aggregated with such Awards under Section 409A of the Code are terminated and liquidated within 30 days before or 12 months after such Change in Control.


        Section 9.
    Adjustments upon Changes in Capitalization.     


        Section 10.
    Termination and Amendment.     

G-16


Table of Contents


        Section 11.
    No Right to Award, Employment or Service.     No Employee, Consultant or Non-Employee Director shall have any claim to be granted any Award under the Plan, and there is no obligation that the terms of Awards be uniform or consistent among Participants. Neither the Plan nor any action taken hereunder shall be construed as giving any Participant any right to be retained in the employ or service of the Company or any Subsidiary. For purposes of this Plan, a transfer of employment or service between the Company and its Subsidiaries shall not be deemed a termination of employment or service; provided, however, that individuals employed by, or otherwise providing services to, an entity that ceases to be a Subsidiary shall be deemed to have incurred a termination of employment or service, as the case may be, as of the date such entity ceases to be a Subsidiary unless such individual becomes an employee of, or service provider to, the Company or another Subsidiary as of the date of such cessation.


        Section 12.
    Taxes.     Each Participant must make appropriate arrangement for the payment of any taxes relating to an Award granted hereunder. The Company or any Subsidiary is authorized to withhold from any payment relating to an Award under the Plan, including from a distribution of Shares or any payroll or other payment to a Participant, amounts of withholding and other taxes due in connection with any transaction involving an Award, and to take such other action as the Committee may deem advisable to enable the Company and Participants to satisfy obligations for the payment of withholding taxes and other tax obligations relating to any Award. This authority shall include the ability to withhold or receive Shares or other property and to make cash payments in respect thereof in satisfaction of a Participant's tax obligations and to require the Participant to enter into elections in respect of taxes. Withholding of taxes in the form of Shares with respect to an Award shall not occur at a rate that exceeds the minimum required statutory federal and state withholding rates. Participants who are subject to the reporting requirements of Section 16 of the Exchange Act shall have the right to pay all or a portion of any withholding or other taxes due in connection with an Award by directing the Company to withhold Shares that would otherwise be received in connection with such Award up to the minimum required withholding amount.


        Section 13.
    Limits on Transferability; Beneficiaries.     No Award or other right or interest of a Participant under the Plan shall be pledged, encumbered, or hypothecated to, or in favor of, or subject to any lien, obligation, or liability of such Participant to, any party, other than the Company or any Subsidiary, or assigned or transferred by such Participant otherwise than by will or the laws of descent

G-17

and distribution, and such Awards and rights shall be exercisable during the lifetime of the Participant only by the Participant or his or her guardian or legal representative. Notwithstanding the foregoing, except as provided in Section 6.1(f)(v), the Committee may, in its discretion, provide that Awards or other rights or interests of a Participant granted pursuant to the Plan be transferable, without consideration, to immediate family members (i.e., children, grandchildren or spouse), to trusts for the benefit of such immediate family members and to partnerships in which such family members are the only partners. The Committee may attach to such transferability feature such terms and conditions as it deems advisable. In addition, a Participant may, in the manner established by the Committee, designate a beneficiary (which may be a natural person or a trust) to exercise the rights of the Participant, and to receive any distribution, with respect to any Award upon the death of the Participant. A beneficiary, guardian, legal representative or other Person claiming any rights under the Plan from or through any Participant shall be subject to all terms and conditions of the Plan and any Award Agreement applicable to such Participant, except as otherwise determined by the Committee, and to any additional restrictions deemed necessary or appropriate by the Committee.


        Section 14.
    Securities Law Requirements.     


        Section 15.
    Code Section 409A.     The Plan and all Awards are intended to comply with, or be exempt from, Code Section 409A and all regulations, guidance, compliance programs and other interpretative authority thereunder, and all provisions of the Plan, including, without limitation, Sections 6, 8 and 9, and any Award Agreement shall be applied and interpreted in a manner consistent therewith. Notwithstanding anything contained herein to the contrary, in the event any Award is subject to Code Section 409A, the Committee may, in its sole discretion and without a Participant's prior consent, amend the Plan and/or Awards, adopt policies and procedures, or take any other actions as deemed appropriate by the Committee to (i) exempt the Plan and/or any Award from the application of Code Section 409A, (ii) preserve the intended tax treatment of any such Award or (iii) comply with the requirements of Code Section 409A. In the event that a Participant is a "specified employee" within the meaning of Code Section 409A, and a payment or benefit provided for under the Plan would be subject to additional tax under Code Section 409A if such payment or benefit is paid within six (6) months after such Participant's separation from service (within the meaning of Code Section 409A), then such payment or benefit shall not be paid (or commence) during the six (6) month period immediately following such Participant's separation from service except as provided in the immediately following sentence. In such an event, any payments or benefits that would otherwise have been made or provided during such six (6) month period and which would have incurred such additional tax under Code Section 409A shall instead be paid to the Participant in a lump-sum

G-18


Table of Contents

payment, without interest, on the earlier of (i) the first business day of the seventh month following such Participant's separation from service or (ii) the tenth business day following such Participant's death. Notwithstanding the foregoing, none of the Company, its Affiliates or their respective directors, officers, employees or advisors will be held liable for any taxes, interest or other amounts owed by any Participant as a result of the application of Code Section 409A.


        Section 16.
    Recoupment.     Any Award granted pursuant to the Plan shall be subject to mandatory repayment by the Participant to the Company pursuant to the terms of any Company "clawback" or recoupment policy.


        Section 17.
    Foreign Participants.     In order to facilitate the making of any grant or combination of grants under this Plan, the Committee may provide for such special terms for Awards to Participants who are foreign nationals, or who are employed by or perform services for the Company or any Subsidiary outside of the United States of America, as the Committee may consider necessary or appropriate to accommodate differences in local law, tax policy or custom. Moreover, the Committee may approve such supplements to, or amendments, restatements or alternative versions of, this Plan as it may consider necessary or appropriate for such purposes without thereby affecting the terms of this Plan as in effect for any other purpose, provided that no such supplements, amendments, restatements or alternative versions shall include any provisions that are inconsistent with the terms of this Plan, as then in effect, unless this Plan could have been amended to eliminate such inconsistency without further approval by the stockholders of the Company.


        Section 18.
    Termination.     Unless earlier terminated, the Plan shall terminate on April 7, 2025, and no Awards under the Plan shall thereafter be granted; provided that no such termination shall impact Awards that were granted prior to such termination.


        Section 19.
    Fractional Shares.     The Company will not be required to issue any fractional Shares pursuant to the Plan. The Committee may provide for the elimination of fractions and settlement of such fractional Shares in cash.


        Section 20.
    Non-Exclusivity of Plan.     Nothing in the Plan shall be construed in any way as limiting the authority of the Committee, the Board, the Company or any Subsidiary or Affiliate to establish any other cash or equity annual or incentive compensation plan or as limiting the authority of any of the foregoing to issue Shares or pay cash bonuses or other supplemental or additional cash or equity incentive compensation to any service provider to the Company, its Subsidiaries or Affiliates, whether or not such person is a Participant in this Plan and regardless of how the number of Shares or the amount of such bonuses or other cash or equity compensation is determined.


        Section 21.
    Discretion.     In exercising, or declining to exercise, any grant of authority or discretion hereunder, the Committee may consider or ignore such factors or circumstances and may accord such weight to such factors and circumstances as the Committee alone and in its sole judgment deems appropriate and without regard to the effect such exercise, or declining to exercise such grant of authority or discretion, would have upon the affected Participant, any other Participant, any Employee, Consultant or Non-Employee Director, the Company, any Subsidiary, any Affiliate of the Company, any stockholder or any other Person.


        Section 22.
    Governing Law.     To the extent that Federal laws do not otherwise control, the validity and construction of the Plan and any Award Agreement entered into thereunder shall be construed and enforced in accordance with the laws of the State of Delaware, but without giving effect to the choice of law principles thereof.


        Section 23.
    Effective Date.     The Plan shall become effective upon the Effective Date.

("NRC Group") pursuant to which, among other things, NRC Group Merger Sub will be merged with and into NRC Group (the "NRC Group Merger") and each outstanding share of the common stock, par value $0.0001 per share, of NRC Group ("NRC Group Common Stock") will be converted into the right to receive 0.196 (such exchange ratio, the "Common Exchange Ratio") of a share of the common stock, par value $0.01 per share, of HoldCo ("HoldCo Common Stock"). The Agreement also provides for, among other things, (i) the conversion of all outstanding shares of 7.00% Series A Convertible Cumulative Preferred Stock of NRC Group into the right to receive shares of HoldCo Common Stock as specified in the Agreement, and (ii) the merger of US Ecology Merger Sub with and into US Ecology (the "US Ecology Merger" and, together with the NRC Group Merger, the "Mergers") pursuant to which each outstanding share of the common stock, par value $0.01 per share, of US Ecology ("US Ecology Common Stock") will be converted into the right to receive one share of HoldCo Common Stock. The terms and conditions of the Mergers and the other transactions contemplated by the Agreement (collectively, the "Transaction") are more fully set forth in the Agreement.

You have requested our opinion as to the fairness, from a financial point of view, to US Ecology of the Common Exchange Ratio provided for in the NRC Group Merger in respect of shares of NRC Group Common Stock.

In connection with this opinion, we have, among other things:

(i)
reviewed certain publicly available business and financial information relating to NRC Group and US Ecology;

(ii)
reviewed certain internal financial and operating information with respect to the business, operations and prospects of NRC Group furnished to or discussed with us by the management of NRC Group, including certain financial forecasts and estimates relating to NRC Group prepared by the management of NRC Group (such forecasts and estimates, the "NRC Group Forecasts"), reviewed certain financial forecasts and estimates relating to NRC Group prepared by the management of US Ecology (such forecasts and estimates, the "US Ecology-NRC Group Forecasts"), and discussed with the management of US Ecology its assessments as to the relative likelihood of achieving the future financial results reflected in the NRC Group Forecasts and the US Ecology-NRC Group Forecasts;

(iii)
reviewed certain internal financial and operating information with respect to the business, operations and prospects of US Ecology furnished to or discussed with us by the management of US Ecology, including certain financial forecasts and estimates relating to US Ecology prepared by the management of US Ecology (such forecasts and estimates, the "US Ecology Forecasts");

(iv)
reviewed certain estimates provided by the management of US Ecology as to the amount and timing of potential cost savings and revenue enhancements anticipated by such management to result from the Transaction (collectively, the "Synergies");

(v)
discussed the past and current business, operations, financial condition and prospects of NRC Group with members of the senior managements of NRC Group and US Ecology, and discussed the past and current business, operations, financial condition and prospects of US Ecology with members of the senior management of US Ecology;

(ix)
reviewed a draft, provided to us on June 23, 2019, of the Agreement; and

In arriving at our opinion, with the consent of US Ecology, we have assumed and relied upon, without independent verification, the accuracy and completeness of the financial and other information and data publicly available or provided to or otherwise reviewed by or discussed with us and have relied upon the assurances of the managements of US Ecology and NRC Group that they are not aware of any facts or circumstances that would make such information or data inaccurate or misleading in any material respect. Based on the assessments of the management of US Ecology as to the relative likelihood of achieving the future financial results reflected in the NRC Group Forecasts and the US Ecology-NRC Group Forecasts, we have relied, at the direction of US Ecology, on the US Ecology-NRC Group Forecasts in evaluating NRC Group for purposes of our analyses and opinion. With respect to the US Ecology-NRC Group Forecasts, the US Ecology Forecasts and the Synergies, we have been advised by US Ecology, and we have assumed, at the direction of US Ecology, that they have been reasonably prepared on bases reflecting the best currently available estimates and good faith judgments of the management of US Ecology as to, and are a reasonable basis upon which to evaluate, the future financial performance of NRC Group and US Ecology, the Synergies and the other matters covered thereby. At the direction of US Ecology, we also have relied on the assessments of the management of US Ecology as to US Ecology's ability to achieve the Synergies and have assumed that such Synergies will be realized in the amounts and at the times projected.

At the direction of US Ecology, we have relied upon the assessments of the managements of US Ecology as to, among other things, (i) the potential impact on NRC Group and US Ecology of certain market, seasonal, cyclical, competitive, geopolitical and macroeconomic and other trends and developments in and prospects for, and governmental, regulatory and legislative matters relating to or otherwise affecting, the environmental, waste and industrial services industry and the markets and geographic regions in which NRC Group and US Ecology operate, (ii) certain accounting matters relating to NRC Group, including with respect to NRC Group's internal controls over financial reporting and remediation of material weaknesses in such controls, (iii) matters relating to prior

acquisitions and predecessor companies of NRC Group and US Ecology, as applicable, including as to financial aspects involved, ongoing obligations, if any, integration and other financial effects, (iv) existing and future agreements and arrangements involving, and the ability to attract, retain and/or replace, key employees, third-party contractors and other commercial relationships of NRC Group and US Ecology, including as to pending and contemplated multi-year, non-recurring and other projects, and (v) the ability to integrate the operations of NRC Group and US Ecology. We have assumed, with the consent of US Ecology, that there will be no developments with respect to any such matters that would have an adverse effect on NRC Group, US Ecology, HoldCo or the Transaction (including the contemplated benefits thereof) or that otherwise would be meaningful in any respect to our analyses or opinion.

We have not made or been provided with any independent evaluation or appraisal of the assets or liabilities (contingent, off-balance sheet, accrued, derivative or otherwise) of NRC Group, US Ecology, HoldCo or any other entity, nor have we made any physical inspection of the properties or assets of NRC Group, US Ecology, HoldCo or any other entity. We have not been requested to make, and we have not made, an independent evaluation of, and we express no opinion or view as to, any pending or potential litigation, claims or governmental, regulatory or other proceedings, actions or investigations or possible unasserted claims or other contingent liabilities affecting NRC Group, US Ecology, HoldCo or any other entity. We have not evaluated the solvency or fair value of NRC Group, US Ecology, HoldCo or any other entity under any state, federal or other laws relating to bankruptcy, insolvency or similar matters. We have assumed, at the direction of US Ecology, that the Transaction will be consummated in accordance with its terms and in compliance with all applicable laws, documents and other requirements, without waiver, modification or amendment of any material term, condition or agreement, and that, in the course of obtaining the necessary governmental, regulatory and other approvals, consents, releases and waivers for the Transaction, no delay, limitation, restriction or condition, including any divestiture requirements or amendments or modifications, will be imposed or occur that would have an adverse effect on NRC Group, US Ecology, HoldCo or the Transaction (including the contemplated benefits thereof) or that otherwise would be meaningful in any respect to our analyses or opinion. We also have assumed, at the direction of US Ecology, that the Transaction will qualify for federal income tax purposes as a reorganization under the provisions of Section 368(a) or an exchange within the meaning of Section 351 of the Internal Revenue Code of 1986, as amended, and otherwise will qualify for the tax treatment contemplated by the Agreement. We further have assumed, at the direction of US Ecology, that the final executed Agreement will not differ in any material respect from the draft reviewed by us.

We express no opinion or view as to any terms or other aspects or implications of the Transaction (other than the Common Exchange Ratio to the extent expressly specified herein), including, without limitation, the form or structure of the Transaction or any terms, aspects or implications of the amended and restated certificate of incorporation of HoldCo or any support agreement, investor agreement, registration rights agreement or other agreements, arrangements or understandings entered into in connection with, related to or contemplated by the Transaction or otherwise. Our opinion is limited to the fairness, from a financial point of view, to US Ecology of the Common Exchange Ratio provided for in the NRC Group Merger in respect of shares of NRC Group Common Stock and no opinion or view is expressed with respect to any consideration received in connection with the Transaction by the holders of any class of securities, creditors or other constituencies of any party. In addition, no opinion or view is expressed with respect to the fairness (financial or otherwise) of the amount, nature or any other aspect of any compensation or other consideration to any of the officers,

directors or employees of any party to the Transaction or any related entities, or class of such persons, relative to the Common Exchange Ratio or otherwise. Furthermore, no opinion or view is expressed as to the relative merits of the Transaction in comparison to other strategies or transactions that might be available to US Ecology or in which US Ecology might engage or as to the underlying business decision of US Ecology to proceed with or effect the Transaction. We are not expressing any opinion as to what the value of HoldCo Common Stock actually will be when issued or the prices at which HoldCo Common Stock, US Ecology Common Stock, NRC Group Common Stock or any other securities may trade or otherwise be transferable at any time, including following announcement or consummation of the Transaction. We also are not expressing any opinion or view with respect to accounting, tax, legal, regulatory or similar matters, including, without limitation, as to tax or other consequences of the Transaction or otherwise or changes in, or the impact of, accounting standards or tax and other laws, regulations and governmental and legislative policies affecting US Ecology, NRC Group, HoldCo or the Transaction, as to which we understand such advice has been obtained as deemed necessary from qualified professionals, and we have relied, at the direction of US Ecology, upon the assessments of representatives of US Ecology and NRC Group as to such matters. In addition, we express no opinion or recommendation as to how any securityholder should vote or act in connection with the Transaction or any other matter.

We have acted as a financial advisor to US Ecology in connection with the Transaction and will receive a fee for our services, of which a portion is payable upon delivery of this opinion and the principal portion is contingent upon consummation of the Transaction. We and certain of our affiliates also expect to participate in the financing for the Transaction, including acting as joint lead arranger in connection with a debt refinancing, for which services we and our affiliates will receive significant compensation. In addition, US Ecology has agreed to reimburse our expenses and indemnify us against certain liabilities arising out of our engagement.

We and our affiliates comprise a full service securities firm and commercial bank engaged in securities, commodities and derivatives trading, foreign exchange and other brokerage activities, and principal investing as well as providing investment, corporate and private banking, asset and investment management, financing and financial advisory services and other commercial services and products to a wide range of companies, governments and individuals. In the ordinary course of our businesses, we and our affiliates may invest on a principal basis or on behalf of customers or manage funds that invest, make or hold long or short positions, finance positions or trade or otherwise effect transactions in equity, debt or other securities or financial instruments (including derivatives, bank loans or other obligations) of US Ecology, HoldCo, NRC Group, J.F. Lehman & Company, LLC, a significant investor of NRC Group, and/or certain of their respective affiliates and/or portfolio companies, as the case may be.

We and our affiliates in the past have provided, currently are providing, and in the future may provide, investment banking, commercial banking and other financial services to US Ecology and have received or in the future may receive compensation for the rendering of these services, including having acted or acting as co-lead arranger and joint bookrunner for, and as a lender (including a letter of credit lender) to, US Ecology under its revolving credit facility.

It is understood that this letter is for the benefit and use of the Board of Directors of US Ecology (in its capacity as such) in connection with and for purposes of its evaluation of the Transaction.

The Board of Directors
NRC Group Holdings Corp.
952 Echo Lane, Suite 460
Houston, Texas 77024

Members of the Board of Directors:

        We understand that NRC Group Holdings Corp. (the "Company") proposes to enter into an Agreement and Plan of Merger, dated as of June 23, 2019 (the "Merger Agreement"), with US Ecology, Inc. ("Parent"), US Ecology Parent, Inc. ("Holdco"), Rooster Merger Sub, Inc., a wholly owned subsidiary of Holdco ("Rooster Merger Sub"), and ECOL Merger Sub, Inc., a wholly owned subsidiary of Holdco ("Parent Merger Sub"), Pursuant to the Merger Agreement, (a) Parent Merger Sub will merge with and into Parent, with Parent continuing as the surviving corporation and as a wholly owned subsidiary of Holdco (the "Parent Merger") and (b) Rooster Merger Sub will merge with and into the Company, with the Company continuing as the surviving corporation and as a wholly owned subsidiary of Holdco (the "Rooster Merger", and together with the Parent Merger, the "Mergers"). As a result of the Parent Merger, each share of Parent Common Stock (as defined in the Merger Agreement), other than Cancelled Parent Common Shares (as defined in the Merger Agreement), will be converted into, and become exchangeable for one share of common stock, par value $0.01 of Holdco ("Holdco Common Stock"). As a result of the Rooster Merger, (i) each outstanding share of common stock, par value $0.0001 per share, of the Company (the "Company Common Stock"), other than Cancelled Common Shares (as defined in the Merger Agreement) will be converted into, and exchangeable for, 0.1960 shares (the "Common Exchange Ratio") of Holdco Common Stock and (ii) each share of 7.00% Series A Convertible Cumulative Preferred Stock (the "Company Series A Preferred Stock"), other than Cancelled Series A Preferred Shares (as defined in the Merger Agreement) and Dissenting Shares, will be converted into, and become exchangeable for, that number of shares of Holdco Common Stock equal to the product of (1) that number of shares of Company Common Stock that such share of Company Series A Preferred Stock could be converted into at the Effective Time (including, for the avoidance of doubt, the applicable Fundamental Change Additional Shares (as defined in the Merger Agreement) and any accumulated and unpaid dividends) multiplied by (2) by the Common Exchange Ratio. The terms and conditions of the Mergers are more fully set forth in the Merger Agreement.

        The Board of Directors of the Company (the "Board of Directors") has asked us whether, in our opinion, the Common Exchange Ratio in the Rooster Merger is fair, from a financial point of view, to the holders of Company Common Stock.

        In connection with rendering our opinion, we have, among other things:

        For purposes of our analysis and opinion, we have assumed and relied upon the accuracy and completeness of the financial and other information publicly available, and all of the information supplied or otherwise made available to, discussed with, or reviewed by us, without any independent verification of such information (and have not assumed responsibility or liability for any independent verification of such information), and have further relied upon the assurances of the management of the Company, Parent and Holdco that they are not aware of any facts or circumstances that would make such information inaccurate or misleading. With respect to the Forecasts, including the Synergies, we have assumed with your consent that they have been reasonably prepared on bases reflecting the best currently available estimates and good faith judgments of the management of the Company as to the future financial performance of the Company, Parent and Holdco and the other matters covered thereby. We have relied, at the direction of the Company, on the assessments of the management of the Company as to Holdco's ability to achieve the Synergies and have been advised by the Company, and have assumed with your consent, that the Synergies will be realized in the amounts and at the times projected. We express no view as to the Forecasts, including Synergies, or the assumptions on which they are based.

        For purposes of our analysis and opinion, we have assumed, in all respects material to our analysis, that, in each case, the final executed Merger Agreement will not differ from the draft Merger Agreement reviewed by us, that the representations and warranties of each party contained in the Merger Agreement are true and correct, that each party will perform all of the covenants and agreements required to be performed by it under the Merger Agreement, and that all conditions to the consummation of the Mergers will be satisfied without waiver or modification thereof. We have further assumed, in all respects material to our analysis, that all governmental, regulatory or other consents, approvals or releases necessary for the consummation of the Mergers will be obtained without any delay, limitation, restriction or condition that would have an adverse effect on the Company, Parent, Holdco or the contemplated benefits to the holders of the Company Common Stock of the Mergers.

        We have not conducted a physical inspection of the properties or facilities of the Company, Parent or Holdco and have not made or assumed any responsibility for making any independent valuation or appraisal of the assets or liabilities (including any contingent, derivative or other off-balance sheet assets and liabilities) of the Company, Parent or Holdco, nor have we been furnished with any such valuations or appraisals, nor have we evaluated the solvency or fair value of the Company, Parent or

Holdco under any state or federal laws relating to bankruptcy, insolvency or similar matters. Our opinion is necessarily based upon information made available to us as of the date hereof and financial, economic, market and other conditions as they exist and as can be evaluated on the date hereof. It is understood that subsequent developments may affect this opinion and that we do not have any obligation to update, revise or reaffirm this opinion.

        We express no opinion with respect to any matter other than the fairness to the holders of the Company Common Stock, from a financial point of view, of the Common Exchange Ratio in the Rooster Merger. We do not express any view on, and our opinion does not address, the fairness of the proposed transaction to, or any consideration received in connection therewith by, the holders of any other class of securities, creditors or other constituencies of the Company, nor as to the fairness of the amount or nature of any compensation to be paid or payable to any of the officers, directors or employees of the Company, or any class of such persons, whether relative to the Common Exchange Ratio or otherwise. We have not been asked to, nor do we express any view on, and our opinion does not address, any other term or aspect of the Merger Agreement or the Mergers, including, without limitation, the structure or form of the Mergers, or any term or aspect of any other agreement or instrument contemplated by the Merger Agreement or entered into or amended in connection with the Merger Agreement. Our opinion does not address the relative merits of the Mergers as compared to other business or financial strategies that might be available to the Company, nor does it address the underlying business decision of the Company to engage in the Mergers. We do not express any view on, and our opinion does not address, what the value of Holdco Common Stock actually will be when issued or the prices at which the Company Common Stock, common stock of Parent or Holdco Common Stock will trade at any time, including following announcement or consummation of the Mergers. In arriving at our opinion, we were not authorized to solicit, and did not solicit, interest from any third-party with respect to the acquisition of any or all of the Company Common Stock or any business combination or other extraordinary transaction involving the Company. Our opinion does not constitute a recommendation to the Board of Directors or to any other persons in respect of the Mergers, including as to how any holder of shares of the Company Common Stock should vote or act in respect of the Mergers. We are not legal, regulatory, accounting or tax experts and have assumed the accuracy and completeness of assessments by the Company and its advisors with respect to legal, regulatory, accounting and tax matters.

        We have acted as financial advisor to the Board of Directors in connection with the Mergers and will receive a fee for our services payable upon rendering this opinion. The Company has also agreed to reimburse our expenses and to indemnify us against certain liabilities arising out of our engagement. During the two year period prior to the date hereof, Evercore Group L.L.C. and its affiliates have not been engaged to provide financial advisory or other services to the Company and we have not received any compensation from the Company during such period. In addition, during the two year period prior to the date hereof, Evercore Group L.L.C. and its affiliates have not been engaged to provide financial advisory or other services to Parent and we have not received any compensation from Parent during such period. We may provide financial advisory or other services to the Company, Parent and Holdco in the future, and in connection with any such services we may receive compensation.

        Evercore Group L.L.C. and its affiliates engage in a wide range of activities for our and their own accounts and the accounts of customers, including corporate finance, mergers and acquisitions, equity sales, trading and research, private equity, placement agent, asset management and related activities. In connection with these businesses or otherwise, Evercore Group L.L.C. and its affiliates and/or our or their respective employees, as well as investment funds in which any of them may have a financial interest, may at any time, directly or indirectly, hold long or short positions and may trade or otherwise effect transactions for their own accounts or the accounts of customers, in debt or equity securities, senior loans and/or derivative products or other financial instruments of or relating to the Company,

ANNEX J

SECTION 262 OF THE DELAWARE GENERAL CORPORATION LAW RIGHTS OF APPRAISAL

        (a)   Any stockholder of a corporation of this State who holds shares of stock on the date of the making of a demand pursuant to subsection (d) of this section with respect to such shares, who continuously holds such shares through the effective date of the merger or consolidation, who has otherwise complied with subsection (d) of this section and who has neither voted in favor of the merger or consolidation nor consented thereto in writing pursuant to § 228 of this title shall be entitled to an appraisal by the Court of Chancery of the fair value of the stockholder's shares of stock under the circumstances described in subsections (b) and (c) of this section. As used in this section, the word "stockholder" means a holder of record of stock in a corporation; the words "stock" and "share" mean and include what is ordinarily meant by those words; and the words "depository receipt" mean a receipt or other instrument issued by a depository representing an interest in 1 or more shares, or fractions thereof, solely of stock of a corporation, which stock is deposited with the depository.

        (b)   Appraisal rights shall be available for the shares of any class or series of stock of a constituent corporation in a merger or consolidation to be effected pursuant to § 251 (other than a merger effected pursuant to § 251(g) of this title), § 252, § 254, § 255, § 256, § 257, § 258, § 263 or § 264 of this title:

J-1


Table of Contents

        (c)   Any corporation may provide in its certificate of incorporation that appraisal rights under this section shall be available for the shares of any class or series of its stock as a result of an amendment to its certificate of incorporation, any merger or consolidation in which the corporation is a constituent corporation or the sale of all or substantially all of the assets of the corporation. If the certificate of incorporation contains such a provision, the provisions of this section, including those set forth in subsections (d), (e), and (g) of this section, shall apply as nearly as is practicable.

        (d)   Appraisal rights shall be perfected as follows:

J-2


Table of Contents

        (e)   Within 120 days after the effective date of the merger or consolidation, the surviving or resulting corporation or any stockholder who has complied with subsections (a) and (d) of this section hereof and who is otherwise entitled to appraisal rights, may commence an appraisal proceeding by filing a petition in the Court of Chancery demanding a determination of the value of the stock of all such stockholders. Notwithstanding the foregoing, at any time within 60 days after the effective date of the merger or consolidation, any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party shall have the right to withdraw such stockholder's demand for appraisal and to accept the terms offered upon the merger or consolidation. Within 120 days after the effective date of the merger or consolidation, any stockholder who has complied with the requirements of subsections (a) and (d) of this section hereof, upon written request, shall be entitled to receive from the corporation surviving the merger or resulting from the consolidation a statement setting forth the aggregate number of shares not voted in favor of the merger or consolidation (or, in the case of a merger approved pursuant to § 251(h) of this title, the aggregate number of shares (other than any excluded stock (as defined in § 251(h)(6)d. of this title)) that were the subject of, and were not tendered into, and accepted for purchase or exchange in, the offer referred to in § 251(h)(2)), and, in either case, with respect to which demands for appraisal have been received and the aggregate number of holders of such shares. Such written statement shall be mailed to the stockholder within 10 days after such stockholder's written request for such a statement is received by the surviving or resulting corporation or within 10 days after expiration of the period for delivery of demands for appraisal under subsection (d) of this section hereof, whichever is later. Notwithstanding subsection (a) of this section, a person who is the beneficial owner of shares of such stock held either in a voting trust or by a nominee on behalf of such person may, in such person's own name, file a petition or request from the corporation the statement described in this subsection.

        (f)    Upon the filing of any such petition by a stockholder, service of a copy thereof shall be made upon the surviving or resulting corporation, which shall within 20 days after such service file in the office of the Register in Chancery in which the petition was filed a duly verified list containing the names and addresses of all stockholders who have demanded payment for their shares and with whom agreements as to the value of their shares have not been reached by the surviving or resulting corporation. If the petition shall be filed by the surviving or resulting corporation, the petition shall be accompanied by such a duly verified list. The Register in Chancery, if so ordered by the Court, shall give notice of the time and place fixed for the hearing of such petition by registered or certified mail to the surviving or resulting corporation and to the stockholders shown on the list at the addresses therein

J-3

stated. Such notice shall also be given by 1 or more publications at least 1 week before the day of the hearing, in a newspaper of general circulation published in the City of Wilmington, Delaware or such publication as the Court deems advisable. The forms of the notices by mail and by publication shall be approved by the Court, and the costs thereof shall be borne by the surviving or resulting corporation.

        (g)   At the hearing on such petition, the Court shall determine the stockholders who have complied with this section and who have become entitled to appraisal rights. The Court may require the stockholders who have demanded an appraisal for their shares and who hold stock represented by certificates to submit their certificates of stock to the Register in Chancery for notation thereon of the pendency of the appraisal proceedings; and if any stockholder fails to comply with such direction, the Court may dismiss the proceedings as to such stockholder. If immediately before the merger or consolidation the shares of the class or series of stock of the constituent corporation as to which appraisal rights are available were listed on a national securities exchange, the Court shall dismiss the proceedings as to all holders of such shares who are otherwise entitled to appraisal rights unless (1) the total number of shares entitled to appraisal exceeds 1% of the outstanding shares of the class or series eligible for appraisal, (2) the value of the consideration provided in the merger or consolidation for such total number of shares exceeds $1 million, or (3) the merger was approved pursuant to § 253 or § 267 of this title.

        (h)   After the Court determines the stockholders entitled to an appraisal, the appraisal proceeding shall be conducted in accordance with the rules of the Court of Chancery, including any rules specifically governing appraisal proceedings. Through such proceeding the Court shall determine the fair value of the shares exclusive of any element of value arising from the accomplishment or expectation of the merger or consolidation, together with interest, if any, to be paid upon the amount determined to be the fair value. In determining such fair value, the Court shall take into account all relevant factors. Unless the Court in its discretion determines otherwise for good cause shown, and except as provided in this subsection, interest from the effective date of the merger through the date of payment of the judgment shall be compounded quarterly and shall accrue at 5% over the Federal Reserve discount rate (including any surcharge) as established from time to time during the period between the effective date of the merger and the date of payment of the judgment. At any time before the entry of judgment in the proceedings, the surviving corporation may pay to each stockholder entitled to appraisal an amount in cash, in which case interest shall accrue thereafter as provided herein only upon the sum of (1) the difference, if any, between the amount so paid and the fair value of the shares as determined by the Court, and (2) interest theretofore accrued, unless paid at that time. Upon application by the surviving or resulting corporation or by any stockholder entitled to participate in the appraisal proceeding, the Court may, in its discretion, proceed to trial upon the appraisal prior to the final determination of the stockholders entitled to an appraisal. Any stockholder whose name appears on the list filed by the surviving or resulting corporation pursuant to subsection (f) of this section and who has submitted such stockholder's certificates of stock to the Register in Chancery, if such is required, may participate fully in all proceedings until it is finally determined that such stockholder is not entitled to appraisal rights under this section.

        (i)    The Court shall direct the payment of the fair value of the shares, together with interest, if any, by the surviving or resulting corporation to the stockholders entitled thereto. Payment shall be so made to each such stockholder, in the case of holders of uncertificated stock forthwith, and the case of holders of shares represented by certificates upon the surrender to the corporation of the certificates representing such stock. The Court's decree may be enforced as other decrees in the Court of Chancery may be enforced, whether such surviving or resulting corporation be a corporation of this State or of any state.

        (j)    The costs of the proceeding may be determined by the Court and taxed upon the parties as the Court deems equitable in the circumstances. Upon application of a stockholder, the Court may order all or a portion of the expenses incurred by any stockholder in connection with the appraisal

proceeding, including, without limitation, reasonable attorney's fees and the fees and expenses of experts, to be charged pro rata against the value of all the shares entitled to an appraisal.

        (k)   From and after the effective date of the merger or consolidation, no stockholder who has demanded appraisal rights as provided in subsection (d) of this section shall be entitled to vote such stock for any purpose or to receive payment of dividends or other distributions on the stock (except dividends or other distributions payable to stockholders of record at a date which is prior to the effective date of the merger or consolidation); provided, however, that if no petition for an appraisal shall be filed within the time provided in subsection (e) of this section, or if such stockholder shall deliver to the surviving or resulting corporation a written withdrawal of such stockholder's demand for an appraisal and an acceptance of the merger or consolidation, either within 60 days after the effective date of the merger or consolidation as provided in subsection (e) of this section or thereafter with the written approval of the corporation, then the right of such stockholder to an appraisal shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery shall be dismissed as to any stockholder without the approval of the Court, and such approval may be conditioned upon such terms as the Court deems just; provided, however that this provision shall not affect the right of any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party to withdraw such stockholder's demand for appraisal and to accept the terms offered upon the merger or consolidation within 60 days after the effective date of the merger or consolidation, as set forth in subsection (e) of this section.

        (l)    The shares of the surviving or resulting corporation to which the shares of such objecting stockholders would have been converted had they assented to the merger or consolidation shall have the status of authorized and unissued shares of the surviving or resulting corporation.
