an advisory basis, of our executive compensation as described in this proxy statement and “FOR the amendment to our 2018 Long-Term Incentive Plan. It is not expected that any additional matters will be brought before the Annual Meeting, but if other matters are properly presented, the persons named as proxies in the proxy card or their substitutes will vote in their discretion on such matters.

Voting via the Internet, mobile device, or by telephone helps save money by reducing postage and proxy tabulation costs. To vote by any of these methods, read this proxy statement, have your Notice of Internet Availability of Proxy Materials, proxy card, or voting instruction form in hand, and follow the instructions below for your preferred method of voting. Each of these voting methods is available 24 hours per day, seven days per week.

We encourage you to cast your vote by one of the following methods:

The way your Units may be voted depends on how your Units are held. If you own Units of record, meaning that your Units are represented by certificates or book entries in your name so that you appear as a unitholder on the records of American Stock Transfer & Trust Company, LLC, our transfer agent, you may vote by proxy, meaning you authorize individuals named in the proxy card to vote your Units. You may provide this authorization by voting via the Internet, mobile device, by telephone, or (if you have received paper copies of our proxy materials) by returning a proxy card. You also may participate in and vote during the Annual Meeting. If you own Units of record and you do not vote by proxy or at the Annual Meeting, your Units will not be voted.

If you own Units in street name, meaning that your Units are held by a bank, brokerage firm, or other nominee, you may instruct that institution on how to vote your shares. You may provide these instructions by voting via the Internet, mobile device, by telephone, or (if you have received paper copies of proxy materials through your bank, brokerage firm, or other nominee) by returning a voting instruction form received from that institution. You also may participate in and vote during the Annual Meeting. If you own Units in street name and do not either provide voting instructions or vote during the Annual Meeting, the institution that holds your Units cannot vote your Units at the Annual Meeting.

Voting Standard

A nominee for director shall be elected to the Board by a plurality of the votes cast, in person or by proxy, by the holders of outstanding Units, voting as a single class. The conversion ratio of preferred units to common units is currently 10-to-1, but may be adjusted to account for unpaid distributions on such preferred units as needed. Abstentions and broker nonvotes will have no effect on the outcome of the election. Broker non-votes occur when a person holding Units in street name, such as through a brokerage firm, does not provide instructions as to how to vote those common units and the broker does not then vote those Units on the unitholder’s behalf.

For all other matters proposed for a vote at the Annual Meeting, the affirmative vote of a majority of the outstanding Units present or represented by proxy and entitled to vote on the matter is

required to approve the matter. For these matters, abstentions are not counted as affirmative votes on a matter but are counted as present and entitled to vote, and broker nonvotes, if any, will have no effect on the outcome of these matters.

Revocation

If you own Units of record, you may revoke your proxy or change your voting instructions at any time before your Units are voted at the Annual Meeting by delivering to the General Partner a written notice of revocation or a duly executed proxy (via the Internet, mobile device, or telephone or by returning a proxy card) bearing a later date or by participating in and voting during the Annual Meeting. A unitholder owning Units in street name may revoke or change voting instructions by contacting the bank, brokerage firm, or other nominee holding the Units or by participating in and voting during the Annual Meeting.

Participating in the Annual Meeting

This year’s Annual Meeting will be accessible through the Internet. We are conducting a virtual online Annual Meeting so our unitholders can participate from any geographic location with Internet connectivity. We believe this enhances accessibility to our Annual Meeting for all of our unitholders and employees.

You are entitled to participate in the Annual Meeting if you were a unitholder as of the close of business on March 15, 2023, the record date, or hold a valid proxy for the meeting. To participate in the Annual Meeting, including to vote and to view the list of registered unitholders as of the record date during the meeting, unitholders of record must access the meeting website at www.proxydocs.com/CEQP and enter the control number found on the Notice of Internet Availability of Proxy Materials or on the proxy card provided to you with this Proxy Statement, or that is set forth within the body of the email sent to you with the link to this Proxy Statement. If your Units are held in street name and your Notice of Internet Availability of Proxy Materials or voting instruction form indicates that you may vote those common units through the www.proxypush.com/CEQP website, then you may access, participate in, and vote at the Annual Meeting with the control number indicated on that Notice of Internet Availability of Proxy Materials or voting instruction form. Otherwise, unitholders who hold their Units in street name should contact their bank, broker, or other nominee (preferably at least five days before the Annual Meeting) and obtain a “legal proxy” to be able to attend, participate in, or vote at the Annual Meeting.

Regardless of whether you plan to participate in the Annual Meeting, it is important that your Units be represented and voted at the Annual Meeting. Accordingly, we encourage you to vote in advance of the Annual Meeting.

Unitholders are able to submit questions for the Annual Meeting’s question and answer session during the meeting. Unitholders who have been provided or obtained a control number may submit a question in advance of the meeting at www.proxydocs.com/CEQP after logging in with that control number. We also will post a replay of the Annual Meeting on our investor relations website, which will be available following the meeting. Additional information regarding the rules and procedures for participating in the Annual Meeting (including any adjournment thereof) will be set forth in our meeting rules of conduct, which unitholders can view during the meeting. The meeting rules, procedures and code of conduct will be posted 15 minutes before the meeting start.

We encourage you to access the Annual Meeting before it begins. Online check-in will be available at 1:45pm CT, approximately 15 minutes before the meeting starts on May 11, 2023. If you have difficulty accessing the meeting, please call the technical support number that will be posted in your instructional email you will receive after registering to attend the Annual Meeting. We will have technicians available to assist you.

Board Skills & Diversity

Director Nominee Tenure, Skills, and Characteristics

In 2021, we established a Nominating and Governance Committee, which meets at least quarterly and reviews the performance, and contributions of existing Board members to the extent they are candidates for re-election and considers all aspects of each candidate’s qualifications and skills in the context of the Partnership’s needs at that point in time. The Nominating and Governance Committee includes, and has any search firm that it engages include, women and individuals from underrepresented racial/ethnic groups in the pool from which the Committee selects director candidates. When considering candidates as potential Board members, the Board and the Nominating and Governance Committee will evaluate the candidates’ ability to contribute to such diversity. The Board assesses its effectiveness in this regard as part of its Board and director evaluation process. Currently, of our three director nominees, one is a woman, all are independent, and two have served for five years or less. The Board’s composition also represents a balanced approach to director tenure, allowing the Board to benefit from the experience of longer-serving directors combined with fresh perspectives from newer directors. The tenure range of our Board is as follows:

Among the qualifications and skills of a candidate considered important by the Nominating and Governance Committee are:

Corporate Governance

Board Leadership

The Board is responsible for the control and direction of the Partnership. The Board represents the unitholders and its primary purpose is to build long-term unitholder value. The Board has no policy that requires that the positions of the Chairman of the Board (the Chairman) and the Chief Executive Officer (CEO) be separate or that they be held by the same individual. The Board believes that this determination should be based on circumstances existing from time to time, including the composition, skills and experience of the Board and its members, specific challenges faced by us or the industry in which it operates, and governance efficiency.

The Chair of the Board is selected by the Board and currently is our Founder and CEO, Robert G. Phillips. The Board believes that this leadership structure is appropriate given Mr. Phillips’ role in founding the Partnership and his significant ownership stake. The Board believes that this leadership structure improves the Board’s ability to focus on key policy and operational issues and helps the Partnership operate in the long-term interests of unitholders.

In addition, the independent directors on the Board have appointed a Lead Director from the Board’s independent directors, currently Warren Gfeller, in order to promote independent leadership of the Board. The lead director presides over the executive sessions of the independent directors (which occur at least once a year), chairs Board meetings in the Chair’s absence, works with management and the independent directors to approve agendas, schedules, information, and

materials for Board meetings, and is available to engage directly with major shareholders where appropriate. In addition, the lead director confers with the Chair of the Board and the independent directors and reviews, as appropriate, the annual schedule of regular Board meetings and major Board meeting agenda topics. The guidance and direction provided by the Lead Director reinforce the Board’s independent oversight of management and contribute to communication among members of the Board.

Director Independence

Because we are a limited partnership, the listing standards of the NYSE do not require that we have a majority of independent directors on the Board, nor that the Partnership establish or maintain a Nominating and Governance Committee or Compensation Committee of the Board. We are, however, required to have an Audit Committee consisting of at least three members, all of whom are required to be independent as defined by the NYSE. The Board has determined that, Warren Gfeller, Janeen Judah, David Lumpkins, Angela Minas, Gary Reaves, John Sherman, Frances Vallejo, and Clay Williams qualify as independent pursuant to independence standards established by the NYSE as set forth in Section 303A.02 of the NYSE Listed Company Manual. To be considered an independent director under the NYSE listing standards, the Board must affirmatively determine that a director has no material relationship with us other than as a director. In making this determination, the Board adheres to all of the specific tests for independence included in the NYSE listing standards and considers all other facts and circumstances it deems necessary or advisable.

A director need not be a member of the General Partner or a Limited Partner; however, a majority of the Directors comprising the Board of Directors must meet the independence standards required of directors who serve on a board of directors established by the Securities Exchange Act of 1934 (the “Exchange Act”) and the rules and regulations of the U.S. Securities and Exchange Commission (the “Commission”) thereunder and by the National Securities Exchange on which the common units are listed or admitted to trading (or if no such National Securities Exchange, the NYSE).

Risk Oversight

The Partnership faces a number of risks, including environmental and regulatory risks, and others, such as the impact of competition. Management is responsible for the day-to-day management of risks the Partnership faces, while the Board, as a whole and through its committees, has responsibility for the oversight of risk management. In fulfilling its risk oversight role, the Board must determine whether risk management processes designed and implemented by our management are adequate and functioning as designed. Senior management regularly delivers presentations to the Board on strategic matters, operations, risk management and other matters, and is available to address any questions or concerns raised by the Board.

Our board committees assist the Board in fulfilling its oversight responsibilities in certain areas of risk. The Audit Committee assists with risk management oversight including in the areas of financial reporting, internal controls and compliance with legal and regulatory requirements and our risk management policy related to our commodity price risk management activities. The Compensation Committee assists the Board with risk management related to our compensation policies and programs. The Sustainability Committee assists the Board on matters relating to sustainability, which include environmental risks and opportunities, social responsibility and impacts, employee, contractor and community health and safety, and activities related to stakeholder engagement and community investment. The Finance Committee assists the Board in fulfilling its oversight responsibilities across the principal areas of corporate finance and financial risk management. The Nominating and Governance Committee assists the Board on matters related to the evaluation of the Board and its standing committees, succession planning of the CEO and key executive officers and oversight responsibilities regarding the governance of the Partnership.

Oversight of Cybersecurity Risk

As with any key operational risk, the Company has a robust governance structure around cybersecurity. Our program is governed at the Board level through the Audit Committee where our Senior Vice President of Internal Audit, Technology and Implementation Services provides quarterly updates to the committee and executive management. Internally, a Cybersecurity Steering Committee, which is represented by a cross-section of leaders, meets on a frequent basis and is responsible for developing the Company’s cybersecurity goals and objectives, reviewing the results of penetration testing and drills, and monitoring current trends and threats. Our framework extends to all stakeholders at the Company where our goal is to protect privacy, equipment and sensitive information in both the corporate network and throughout our field operations.

Risk Assessment in Compensation Programs

During the year our Compensation Committee conducted an analysis of potential risks posed by the Company’s compensation program, asking, in essence, whether the program might encourage the executive officers to take unnecessary or excessive risks, or whether the program might encourage the manipulation of reported earnings. As part of its analysis, the Compensation Committee also considered mitigating factors and controls. Based on its analysis, the Compensation Committee determined that our compensation program is unlikely to motivate inappropriate risk-taking.

Board Evaluation

On an annual basis we conduct a comprehensive Board self-evaluation to assess the effectiveness of our Board, committees, and members. The Board conducts annual evaluations through the use of both individual interviews by the Lead Director with each Board member and a written questionnaire completed by all Board members that covers a broad range of matters relating to governance, meetings, materials, and other agenda topics.

The Board and senior executives then review and discuss the evaluation results and any actions to be taken. The results are used to inform Board and committee composition and refreshment, including potential expansion and refinement of the attributes and experience criteria for Board membership, and to address the evolving needs of the Company. The evaluation aims (1) to find opportunities where the Board and committees can improve their performance and effectiveness, (2) to assess any need to evolve the composition and expertise of the Board, and (3) to assure that our Board and committees are operating in accordance with our Corporate Governance Guidelines, committee charters and best practices.

Code of Ethics

Crestwood is committed to running an ethical business, which is supported by our clearly articulated policies and rigorous management systems and processes. We have adopted a Code of Business Conduct and Ethics that outlines our guiding principles and expectations, which can be found at www.crestwoodlp.com/investors/governance.

Each officer, director and employee is responsible for upholding our standards for ethics and integrity as set forth in the Code. Every two years all directors and employees are required to complete ethics training on our Code.

Any employee witnessing a violation of the Code is asked to report their concern through our independent Ethics Hotline, which is available 24 hours a day, seven days a week. All employees receive regular communication about the hotline to ensure that everyone knows their reporting options and understands Crestwood’s commitment to ethics and integrity. Our compliance team takes all concerns seriously and follows the necessary protocols and processes to quickly resolve them. We maintain absolute anonymity, to the extent possible, and empower any employee reporting a violation to discuss their concern without fear of retaliation.

We track the number of requests made and the length of time from reporting to resolution to evaluate the success of the hotline. Any ethics violations and results of the whistleblower hotline are reported to the Audit Committee by our Chief Compliance Officer, who also shares quarterly general ethics updates with the Board.

Corporate Governance Guidelines

The Board has adopted a robust set of Corporate Governance Guidelines that addresses the goals and expectations with respect to key corporate governance matters. The Guidelines address the following topics:

Director Common Unit Ownership Guidelines

Directors who are not also executive officers of the Company are required to hold common units with a value equal to five times the amount of the annual retainer paid to directors. Until such guideline is met, a director is required to retain 100% of all vested equity awards under the Company’s director compensation program.

Communications with Directors

Parties wishing to send written communications to the Board, other than sales-related communications, should send a letter addressed to the member or members of the Board to whom the communication is directed, care of the Corporate Secretary, 811 Main St., Suite 3400, Houston, Texas 77002. All such communications will be forwarded to the Board member or members specified.

Director Attendance at Annual Meetings

The Company does not have a formal policy with respect to director attendance at annual unitholder meetings. In 2022, all members of the Board were in attendance at the annual meeting.

Please visit our investor relations website at www.crestwoodlp.com/investors, “Governance,” for additional information on our corporate governance.

Board Meetings and Committees

The Board meets in regularly scheduled sessions and holds special meetings and acts by unanimous written consent whenever circumstances require such meetings. Our independent directors meet in executive session at least once a year. During 2022, there were 13 total meetings of the Board. All incumbent directors attended at least 97% of the aggregate of the meetings of the Board and committees on which they served occurring during 2022.

The Board has established an Audit Committee, a Compensation Committee, a Finance Committee, a Nominating and Governance Committee and a Sustainability Committee, each of which is comprised entirely of directors who meet the applicable independence requirements of the NYSE rules. The committees keep the Board informed of their actions and provide assistance to the Board in fulfilling its oversight responsibility to unitholders. The table below provides current board membership information as well as committee meeting information for the last fiscal year.

Committee Oversight

Director Nominations

Pursuant to Section 13.4(b)(vi) of our Partnership Agreement, nominations of persons for election of directors to the Board may be made at an annual meeting of the Partnership (a) by or at the direction of a majority of the directors then in office or (b) by a limited partner (i.e. a unitholder) or group of limited partners (a “limited partner group”), that holds or beneficially owns, and has continuously held without interruption for the prior two years, at least 10% of the outstanding common units or outstanding preferred units that on a converted basis represent at least 10% of the outstanding common units, or any combination thereof.

Any eligible unitholders or limited partner group that wishes to submit a director nomination for the 2023 Annual Meeting must deliver written notice thereof to the General Partner at 811 Main Street, Suite 3400, Houston, Texas 77002. The written notice must comply with Section 13.4(b)(vi)(A)(2) of our Partnership Agreement and the procedures set forth in Section 13.4(b)(vi)(C) of our Partnership Agreement, including the information requirements included in 13.4(b)(vi)(A)(2) of our Partnership Agreement. The Chairman designated by the General Partner pursuant to Section 13.10 of our Partnership Agreement shall have the power and duty to (a) determine whether a nomination was made in accordance with the above procedures and (b) declare that such nomination shall be disregarded if any proposed nomination was not made in compliance with Section 13.4(b) of our Partnership Agreement.

If each member of the limited partner group (or a qualified representative of each member) does not appear at the annual meeting to present a nomination, such nomination shall be disregarded notwithstanding that proxies in respect of such vote may have been received by the General Partner or the Partnership. To be considered a qualified representative of a member of the limited partner group, a person must be a duly authorized officer, manager or partner of such limited partner or must be authorized by a writing executed by such limited partner or an electronic transmission delivered by such limited partner to act for such limited partner as proxy at the meeting of limited partners and such person must produce such writing or electronic transmission, or a reliable reproduction of the writing or electronic transmission at the meeting of limited partners.

Compensation of Directors

Officers of the General Partner who also serve as directors, such as Mr. Phillips, do not receive additional compensation. All of the non-employee directors except for Mr. Reaves receives cash compensation of $100,000 per year for serving on the Board. The Lead Director, Audit Committee chairperson, Finance Committee chairperson, Compensation Committee chairperson, Nominating and Governance Committee chairperson and Sustainability Committee chairperson each receive additional cash compensation of $20,000 per year. In August 2022, the Compensation Committee approved additional annual compensation in the amount of $10,000 be paid to any non-employee director that serves on three or more board committees. All cash compensation is paid to the non-employee directors in quarterly installments. Additionally, each non-employee director receives an annual grant of restricted units under our long-term incentive plan equal to approximately $110,000 in value that vests on the first anniversary of the date of issuance. Each grant compensates for future performance, and generally no portion of a restricted unit vests until the year after it is granted. If a director leaves the Board prior to a vest date for any reason other than a Change of Control (as defined under our long-term incentive plan), death or Permanent Disability, he or she will forfeit all or any portion of the restricted units that has not previously vested, unless vesting is otherwise accelerated at the discretion of the Compensation Committee. If the director’s service relationship ends due to a Change of Control or the director’s death or Permanent Disability, then the forfeiture restrictions lapse and the award vests in full. Permanent Disability means the director’s inability, with or without reasonable accommodation, by reason of illness, incapacity, or other disability, to perform his or her duties, as determined by the Board for a cumulative total of 180 days in any 12-month period. Each non-employee director is reimbursed for out-of-pocket expenses in connection with attending meetings of the Board or committees.

The following table sets forth, for the year ended December 31, 2022, all compensation reportable for directors who served during 2022, as determined by SEC rules.

Director Compensation for 2022

Sustainability Strategy Highlights in 2022

Carbon Management Plan

Carbon management is a leading component of our three-year sustainability strategy. Published in January 2022, our carbon management plan outlines near-term emissions reduction activities that we intend to implement and highlights not only a series of commitments, but also the mechanisms for achievement of those commitments as we continue to expand our leading Gathering and Processing asset portfolio. In 2022, we made significant strides in executing upon key deliverables outlined in the carbon management plan.

Crestwood’s ESG Journey: 2018-2022

While we have always had ESG ingrained in our values, Crestwood formalized its ESG governance framework in September 2018, which included establishing a Sustainability Committee and dedicated ESG function to provide oversight and integrate sustainability further into the organization.
