Investment objective

The Fund seeks maximum long-term capital growth through capital appreciation.

Market review

The healthcare sector continued to experience significant challenges during the Fund’s fiscal year ended March 31, 2023. At the beginning of the period, biotechnology companies underperformed as investors turned away from this subsector amid fears of slowing global economic growth and recession in the US. Managed care companies performed strongly as these companies tend to better weather inflationary pressure while many healthcare suppliers and medical device companies struggled with staffing shortages and supply chain disruptions early in the fiscal year. Persistent concerns about rising inflation and interest rate increases by the US Federal Reserve contributed to profit taking in the sector. Major events such as merger-and-acquisitions news about Amgen’s acquisition of Horizon Therapeutics PLC following bids from Sanofi and Johnson & Johnson, and strong earnings and promising clinical trials results were bright spots in the sector during the period.

Contributors to the Fund’s relative performance were:

· holdings in biotechnology

· favorable stock selection in the bluechip medical products sector.

Portfolio management review
Delaware Healthcare Fund

Within the Fund

For the fiscal year ended March 31, 2023, Delaware Healthcare Fund declined, although it outperformed its benchmark, the Russell 3000^®Healthcare Index. The Fund’s Institutional Class shares declined 2.73%. The Fund’s Class A shares declined 2.58% at net asset value (NAV) and declined 8.56% at maximum offer price. These figures reflect all distributions reinvested. During the same period, the benchmark declined 4.84%. For complete, annualized performance of Delaware Healthcare Fund, please see the table on page 4.

Among sectors, the Fund’s holdings in biotechnology contributed the most to relative performance as a result of both favorable asset allocation and stock selection. Shares of Regeneron Pharmaceuticals Inc. outperformed for the period after the company announced positive data from late phase trials of chronic obstructive pulmonary disease (COPD) drug Dupixent, which the company had developed in partnership with Sanofi. Shares of Seagen Inc., also in the biotechnology sector, rose following the announcement that Pfizer would acquire the company. Shares of Viking Therapeutics Inc. rose sharply at the end of the period. Viking Therapeutics, which focuses on treating metabolic and endocrine disorders, released positive early-stage study results for the subcutaneous use of its experimental weight loss drug. Weight loss drugs have become popular recently, and these results show promise for potential future revenue sources in the company’s pipeline. Conversely, the Fund’s overweight position in Arcus Biosciences Inc. detracted from relative performance after it announced mixed results in trials for its lung cancer drug.

Elsewhere, the Fund’s underweight positioning in the small- to mid-cap medical products sector also contributed to relative performance. Within the sector, the Fund’s underweight to Edwards Lifesciences Corp., Danaher Corp, and Intuitive Surgical Inc. was favorable in terms of asset allocation as all these companies underperformed for the fiscal year. On the negative side, the Fund’s overweight position in Illumina Inc. detracted from relative performance. Shares declined in May 2022 after a jury ruled against Illumina in a patent infringement case and the company guided to softer-than-predicted quarterly results. While the patent infringement case carries some risk to earnings, Illumina is expected to appeal and may have multiple ways to potentially mitigate the impact. We believe Illumina remains a leader in genome-analysis technology and trades at a discount to its intrinsic value.

While an underweight position in the pharmaceutical contract research and healthcare information technology (IT) sector also contributed to relative performance during the period, we do not find any companies within the sector that meet our investment criteria.

Favorable stock selection drove performance in the blue-chip medical products sector. The Fund’s underweight stance in Johnson & Johnson and Medtronic PLC was favorable in terms of asset allocation. The Fund’s overweight position in Amgen Inc. also added to relative performance due to positive earnings results and continued progress in the company’s pipeline. Conversely, overweight positions in Roche Holding AG and Chugai Pharmaceutical Co. Ltd. detracted from relative performance. Shares of Roche declined in May 2022 following the failure of a

Table of Contents

phase 3 trial for its lung cancer drug Tecentriq. Despite this near-term underperformance, we believe Roche has a strong pipeline and trades at a discount to its intrinsic value. Shares of Chugai underperformed due to earnings results that slightly underwhelmed and a lack of near-term catalysts. Chugai is among the strongest franchises in Japan and is also partnered with Roche. This allows Chugai to benefit from both companies’ pipelines and we find this positive. As such, we believe Chugai continues to have an attractive platform of hemophilia and oncology drugs.

The Fund used derivatives, foreign currency exchange contracts, during the fiscal year. However, these had a minimal effect on performance.

As global healthcare investors, we think that short-term legislative risks and judicial action could possibly overshadow what we view as the positive long-term fundamentals of the sector and specific companies. In our opinion, there are tremendous long-term opportunities in the global healthcare asset class. The baby-boomer generation in America is aging, implying expanding demand for healthcare products and services for decades to come. At the same time, middle classes in countries with emerging economies (notably India and China) are growing rapidly, creating big appetites for Western-style medicine. We remain positive on the sector and its potential for growth.

We believe healthcare remains one of the few growth sectors in the US economy. We continue to see what we view as many attractive opportunities in the healthcare sector, particularly within biotechnology sector, where we see potential for continued innovation in cancer treatments and gene-therapy technology. We remain overweight in the biotechnology sector, particularly in small- to mid-cap companies, where we see potential for technological breakthroughs.

We continue putting a premium on disciplined, intensive research when analyzing investment opportunities for the Fund and tend to favor companies that exhibit such traits as:

· proven competitiveness

· seasoned management teams

· stock valuations that are discounted meaningfully from our estimates of intrinsic value.

These characteristics are part of our daily considerations as we follow our conservative, stock-by-stock approach to the Fund’s portfolio management.

¹Returns reflect the reinvestment of all distributions and are presented both with and without the applicable sales charges described below. Returns do not reflect the deduction of taxes the shareholder would pay on Fund distributions or redemptions of Fund shares.

Expense limitations were in effect for certain classes during some or all of the periods shown in the “Fund and benchmark performance” table. Expenses for each class are listed in the “Fund expense ratios” table on page 5. Performance would have been lower had expense limitations not been in effect.

Class A shares are sold with a maximum front-end sales charge of 5.75%, and have an annual distribution and service (12b-1) fee of 0.25% of average daily net assets.

Performance for Class A shares, excluding sales charges, assumes that no front-end sales charge applied.

Class C shares are sold with a contingent deferred sales charge (CDSC) of 1.00% if redeemed during the first 12 months. They are also subject to an annual 12b-1 fee of 1.00% of average daily net assets. Performance for Class C shares, excluding sales charges, assumes either that CDSCs did not apply or that the investment was not redeemed.

Class R shares are available only for certain retirement plan products. They are sold without a sales charge and have an annual 12b-1 fee of 0.50% of average daily net assets.

Institutional Class shares are not subject to a sales charge and are offered for sale

exclusively to certain eligible investors. In addition, Institutional Class shares pay no 12b-1 fee.

Narrowly focused investments may exhibit higher volatility than investments in multiple industry sectors.

Healthcare companies are subject to extensive government regulation and their profitability can be affected by restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure, and malpractice or other litigation.

International investments entail risks including fluctuation in currency values, differences in accounting principles, or economic or political instability. Investing in emerging markets can be riskier than investing in established foreign markets due to increased volatility, lower trading volume, and higher risk of market closures. In many emerging markets, there is substantially less publicly available information and the available information may be incomplete or misleading. Legal claims are generally more difficult to pursue.

“Non-diversified” funds may allocate more of their net assets to investments in single securities than “diversified” funds. Resulting adverse effects may subject these funds to greater risks and volatility.

The disruptions caused by natural disasters, pandemics, or similar events could prevent the Fund from executing advantageous investment decisions in a timely manner and could negatively impact the Fund’s ability to achieve its investment objective and the value of the Fund’s investments.

²The Fund’s expense ratios, as described in the most recent prospectus, are disclosed in the following “Fund expense ratios” table. The expense ratios below may differ from the expense ratios in the “Financial highlights” since they are based on different time periods and the expense ratios in the prospectus include acquired fund fees and expenses, if any. See Note 2 in “Notes to financial statements” for additional details. Please see the “Financial highlights” section in this report for the most recent expense ratios.

Disclosure of Fund expenses

For the six-month period from October 1, 2022 to March 31, 2023 (Unaudited)

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments, reinvested dividends, or other distributions; redemption fees; and exchange fees; and (2) ongoing costs, including management fees; distribution and service (12b-1) fees; and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire six-month period from October 1, 2022 to March 31, 2023.

Actual expenses

The first section of the table shown, “Actual Fund return,” provides information about actual account values and actual expenses. You may use the information in this section of the table, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first section under the heading entitled “Expenses Paid During Period” to estimate the expenses you paid on your account during this period.

Hypothetical example for comparison purposes

The second section of the table shown, “Hypothetical 5% return,” provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads), redemption fees, or exchange fees. Therefore, the second section of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. The Fund’s expenses shown in the table reflect fee waivers in effect and assume reinvestment of all dividends and distributions.

*“Expenses Paid During Period” are equal to the Fund’s annualized expense ratio, multiplied by the average account value over the period, multiplied by 182/365 (to reflect the one-half year period).

^†Because actual returns reflect only the most recent six-month period, the returns shown may differ significantly from fiscal year returns.

In addition to the Fund’s expenses reflected above, the Fund also indirectly bears its portion of the fees and expenses of any investment companies (Underlying Funds) in which it invests. The table above does not reflect the expenses of any Underlying Funds.

Delaware Healthcare Fund

March 31, 2023

Delaware Group^® Equity Funds IV (Trust) is organized as a Delaware statutory trust and offers 10 series. These financial statements and the related notes pertain to Delaware Healthcare Fund (Fund). The Trust is an open-end investment company. The Fund is considered nondiversified under the Investment Company Act of 1940, as amended (1940 Act), and offers Class A, Class C, Class R, and Institutional Class shares. Class A shares are sold with a maximum front-end sales charge of 5.75%. There is no front-end sales charge when you purchase $1 million or more of Class A shares. However, if Delaware Distributors, L.P. (DDLP) paid your financial intermediary a commission on your purchase of $1 million or more of Class A shares, you will have to pay a Limited CDSC of 1.00% if you redeem these shares within the first 18 months after your purchase, unless a specific waiver of the Limited CDSC applies. Class C shares have no upfront sales charge, but are sold with a contingent deferred sales charge (CDSC) of 1.00%, which will be incurred if redeemed during the first 12 months. Class R and Institutional Class shares are not subject to a sales charge and are offered for sale exclusively to certain eligible investors.

1. Significant Accounting Policies

The Fund follows accounting and reporting guidance under Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946, Financial Services — Investment Companies. The following accounting policies are in accordance with US generally accepted accounting principles (US GAAP) and are consistently followed by the Fund.

Security Valuation — Equity securities and exchange-traded funds (ETFs), except those traded on the Nasdaq Stock Market LLC (Nasdaq), are valued at the last quoted sales price as of the time of the regular close of the New York Stock Exchange on the valuation date. Equity securities and ETFs traded on the Nasdaq are valued in accordance with the Nasdaq Official Closing Price, which may not be the last sales price. If, on a particular day, an equity security or ETF does not trade, the mean between the bid and the ask prices will be used, which approximates fair value. Equity securities listed on a foreign exchange are normally valued at the last quoted sales price on the valuation date. Open-end investment companies, other than ETFs, are valued at their published net asset value (NAV). Foreign currency exchange contracts are valued at the mean between the bid and the ask prices, which approximates fair value. Interpolated values are derived when the settlement date of the contract is an interim date for which quotations are not available. Generally, other securities and assets for which market quotations are not readily available are valued at fair value as determined in good faith by the Fund's valuation designee, Delaware Management Company (DMC). Subject to the oversight of the Trust's Board of Trustees (Board), DMC, as valuation designee, has adopted policies and procedures to fair value securities for which market quotations are not readily available consistent with the requirements of Rule 2a-5 under the 1940 Act. In determining whether market quotations are readily available or fair valuation will be used, various factors will be taken into consideration, such as market closures or suspension of trading in a security. Restricted securities and private placements are valued at fair value.

Table of Contents

Federal and Foreign Income Taxes — No provision for federal income taxes has been made as the Fund intends to continue to qualify for federal income tax purposes as a regulated investment company under Subchapter M of the Internal Revenue Code of 1986, as amended, and make the requisite distributions to shareholders. The Fund evaluates tax positions taken or expected to be taken in the course of preparing the Fund’s tax returns to determine whether the tax positions are “more-likely-than-not” of being sustained by the applicable tax authority. Tax positions not deemed to meet the “more-likely-than-not” threshold are recorded as a tax benefit or expense in the current year. Management has analyzed the Fund’s tax positions taken or expected to be taken on the Fund’s federal income tax returns through the year ended March 31, 2023, and for all open tax years (years ended March 31, 2020–March 31, 2022), and has concluded that no provision for federal income tax is required in the Fund’s financial statements. In regard to foreign taxes only, the Fund has open tax years in certain foreign countries in which it invests that may date back to the inception of the Fund. If applicable, the Fund recognizes interest accrued on unrecognized tax benefits in interest expense and penalties in "Other" on the “Statement of operations.” During the year ended March 31, 2023, the Fund did not incur any interest or tax penalties.

Foreign Currency Transactions — Transactions denominated in foreign currencies are recorded at the prevailing exchange rates on the valuation date. The value of all assets and liabilities denominated in foreign currencies is translated daily into US dollars at the exchange rate of such currencies against the US dollar. Transaction gains or losses resulting from changes in exchange rates during the reporting period or upon settlement of the foreign currency transaction are reported in operations for the current period. The Fund generally does not bifurcate that portion of realized gains and losses on investments which is due to changes in foreign exchange rates from that which is due to changes in market prices. These gains and losses are included on the “Statement of operations” under “Net realized gain (loss) on investments.” The Fund reports certain foreign currency related transactions as components of realized gains (losses) for financial reporting purposes, whereas such components are treated as ordinary income (loss) for federal income tax purposes.

Derivative Financial Instruments — The Fund may invest in various derivative financial instruments. These instruments are used to obtain exposure to a security, commodity, index, market, and/or other assets without owning or taking physical custody of securities, commodities and/or other referenced assets or to manage market, equity, credit, interest rate, foreign currency exchange rate, commodity and/or other risks. Derivative financial instruments may give rise to a form of economic leverage and involve risks, including the imperfect correlation between the value of a derivative financial instrument and the underlying asset, possible default of the counterparty to the transaction or illiquidity of the instrument. Pursuant to Rule 18f-4 under the 1940 Act, among other things, the Fund must either use derivative financial instruments with

embedded leverage in a limited manner or comply with an outer limit on fund leverage risk based on value-at-risk. The Fund's successful use of a derivative financial instrument depends on the investment adviser's ability to predict pertinent market movements accurately, which cannot be assured. The use of these instruments may result in losses greater than if they had not been used, may limit the amount of appreciation the Fund can realize on an investment and/or may result in lower distributions paid to shareholders. The Fund's investments in these instruments, if any, are discussed in detail in the Notes to financial statements.

Segregation and Collateralizations — In certain cases, based on requirements and agreements with certain exchanges and third-party broker-dealers, the Fund may deliver or receive collateral in connection with certain investments (e.g., futures contracts, foreign currency exchange contracts, options written, securities with extended settlement periods, and swaps). Certain countries require that cash reserves be held while investing in companies incorporated in that country. These cash reserves and cash collateral that has been pledged/received to cover obligations of the Fund under derivative contracts, if any, will be reported separately on the "Statement of assets and liabilities" as cash collateral due to/from broker. Securities collateral pledged for the same purpose, if any, is noted on the "Schedule of investments."

Use of Estimates — The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the fair value of investments, the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates and the differences could be material.

Other — Expenses directly attributable to the Fund are charged directly to the Fund. Other expenses common to various funds within the Delaware Funds by Macquarie^® (Delaware Funds) are generally allocated among such funds on the basis of average net assets. Management fees and certain other expenses are paid monthly. Security transactions are recorded on the date the securities are purchased or sold (trade date) for financial reporting purposes. Costs used in calculating realized gains and losses on the sale of investment securities are those of the specific securities sold. Dividend income is recorded on the ex-dividend date and interest income is recorded on an accrual basis. Income and capital gain distributions from any investment companies (Underlying Funds) in which the Fund invests are recorded on the ex-dividend date. Foreign dividends are also recorded on the ex-dividend date or as soon after the ex-dividend date that the Fund is aware of such dividends, net of all tax withholdings, a portion of which may be reclaimable. Withholding taxes and reclaims on foreign dividends have been recorded in accordance with the Fund’s understanding of the applicable country’s tax rules and rates. The Fund declares and pays dividends from net investment income and distributions from net realized gain on investments, if any, at least annually. The Fund may distribute more frequently, if necessary for tax purposes. Dividends and distributions, if any, are recorded on the ex-dividend date.

Table of Contents

The Fund receives earnings credits from its transfer agent when positive cash balances are maintained, which may be used to offset transfer agent fees. If the amount earned is greater than $1, the expenses paid under this arrangement are included on the “Statement of operations” under “Dividend disbursing and transfer agent fees and expenses” with the corresponding expenses offset included under “Less expenses paid indirectly.”

2. Investment Management, Administration Agreements, and Other Transactions with Affiliates

In accordance with the terms of its investment management agreement, the Fund pays DMC, a series of Macquarie Investment Management Business Trust and the investment manager, an annual fee which is calculated daily and paid monthly at the rates of 0.85% on the first $500 million of average daily net assets of the Fund, 0.80% on the next $500 million, 0.75% on the next $1.5 billion, and 0.70% on average daily net assets in excess of $2.5 billion.

DMC has contractually agreed to waive all or a portion of its investment advisory fees and/or pay/reimburse expenses (excluding any distribution and service (12b-1) fees, taxes, interest, acquired fund fees and expenses, short sale dividend and interest expenses, brokerage fees, certain insurance costs, and non-routine expenses or costs, including, but not limited to, those relating to reorganizations, litigation, conducting shareholder meetings, and liquidations), in order to prevent total annual fund operating expenses from exceeding 0.96% of the Fund’s average daily net assets from July 29, 2022 through March 31, 2023.* These waivers and reimbursements may only be terminated by agreement of DMC and the Fund. The waivers and reimbursements are accrued daily and received monthly.

DMC entered into Sub-Advisory Agreements on behalf of the Fund with Macquarie Funds Management Hong Kong Limited and Macquarie Investment Management Global Limited, each of which is an affiliate of DMC (“Affiliated Sub-Advisor”). Pursuant to the terms of the relevant Sub-Advisory Agreement, the investment sub-advisory fee is paid by DMC to each Affiliated Sub-Advisor based on the extent to which an Affiliated Sub-Advisor provides services to the Fund.

Delaware Investments Fund Services Company (DIFSC), an affiliate of DMC, provides fund accounting and financial administrative oversight services to the Fund. For these services, DIFSC’s fees are calculated daily and paid monthly, based on the aggregate daily net assets of all funds within the Delaware Funds at the following annual rates: 0.00475% of the first $35 billion; 0.0040% of the next $10 billion; 0.0025% of the next $45 billion; and 0.0015% of aggregate average daily net assets in excess of $90 billion (Total Fee). Each fund in the Delaware Funds pays a minimum of $4,000, which, in aggregate, is subtracted from the Total Fee. Each fund then pays its portion of the remainder of the Total Fee on a relative NAV basis. This amount is included on the “Statement of operations” under “Accounting and administration expenses.” For the year ended March 31, 2023, the Fund paid $28,804 for these services.

$20 billion; 0.011% of the next $5 billion; 0.007% of the next $5 billion; 0.004% of the next $20 billion; 0.002% of the next $25 billion; and 0.0015% of average daily net assets in excess of $75 billion. The fees payable to DIFSC under the shareholder services agreement described above are allocated among all retail funds in the Delaware Funds on a relative NAV basis. This amount is included on the “Statement of operations” under “Dividend disbursing and transfer agent fees and expenses.” For the year ended March 31, 2023, the Fund paid $398,371 for these services. Pursuant to a sub-transfer agency agreement between DIFSC and BNY Mellon Investment Servicing (US) Inc. (BNYMIS), BNYMIS provides certain sub-transfer agency services to the Fund. Sub-transfer agency fees are paid by the Fund and are also included on the “Statement of operations” under “Dividend disbursing and transfer agent fees and expenses.” The fees that are calculated daily and paid as invoices are received on a monthly or quarterly basis.

For the year ended March 31, 2023, DDLP earned $84,878 for commissions on sales of the Fund’s Class A shares. For the year ended March 31, 2023, DDLP received gross CDSC commissions of $3,342 and $1,175 on redemptions of the Fund’s Class A and Class C shares, respectively, and these commissions were entirely used to offset upfront commissions previously paid by DDLP to broker/dealers on sales of those shares.

Trustees’ fees include expenses accrued by the Fund for each Trustee’s retainer and meeting fees. Certain officers of DMC, DIFSC, and DDLP are officers and/or Trustees of the Trust. These officers and Trustees are paid no compensation by the Fund.

In addition to the management fees and other expenses of the Fund, the Fund indirectly bears the investment management fees and other expenses of any Underlying Funds, including ETFs in which it invests. The amount of these fees and expenses incurred indirectly by the Fund will vary based upon the expense and fee levels of any Underlying Funds and the number of shares that are owned of any Underlying Funds at different times.

*The aggregate contractual waiver period covering this report is from July 29, 2022 through July 29, 2023.

3. Investments

For the year ended March 31, 2023, the Fund made purchases and sales of investment securities other than short-term investments as follows:

Purchases		$	22,362,478
Sales			97,894,963

The tax cost of investments includes adjustments to net unrealized appreciation (depreciation) which may not necessarily be the final tax cost basis adjustments but which approximate the tax basis unrealized gains and losses that may be realized and distributed to shareholders. At March 31, 2023, the cost and unrealized appreciation (depreciation) of investments for federal income tax purposes for the Fund were as follows:

Cost of investments	$	638,299,994
Aggregate unrealized appreciation of investments	$	345,293,738
Aggregate unrealized depreciation of investments		(158,388,733	)
Net unrealized appreciation of investments	$	186,905,005

US GAAP defines fair value as the price that the Fund would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date under current market conditions. A three-level hierarchy for fair value measurements has been established based upon the transparency of inputs to the valuation of an asset or liability. Inputs may be observable or unobservable and refer broadly to the assumptions that market participants would use in pricing the asset or liability. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the reporting entity’s own assumptions about the assumptions that market participants would use in pricing the asset or liability based on the best information available under the circumstances. The Fund's investment in its entirety is assigned a level based upon the observability of the inputs which are significant to the overall valuation. The three-level hierarchy of inputs is summarized as follows:

Level 1 –

Inputs are quoted prices in active markets for identical investments. (Examples: equity securities, open-end investment companies, futures contracts, and exchange-traded options contracts)

Level 2 –

Other observable inputs, including, but not limited to: quoted prices for similar assets or liabilities in markets that are active, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks, and default rates) or other market-corroborated inputs. (Examples: debt securities, government securities, swap

3. Investments (continued)

	contracts, foreign currency exchange contracts, foreign securities utilizing international fair value pricing, broker-quoted securities, and fair valued securities)

Level 3 –	Significant unobservable inputs, including the Fund's own assumptions used to determine the fair value of investments. (Examples: broker-quoted securities and fair valued securities)

Level 3 investments are valued using significant unobservable inputs. The Fund may also use an income-based valuation approach in which the anticipated future cash flows of the investment are discounted to calculate fair value. Discounts may also be applied due to the nature or duration of any restrictions on the disposition of the investments. Valuations may also be based upon current market prices of securities that are comparable in coupon, rating, maturity, and industry. The derived value of a Level 3 investment may not represent the value which is received upon disposition and this could impact the results of operations.

The following table summarizes the valuation of the Fund's investments by fair value hierarchy levels as of March 31, 2023:

	Level 1		Level 2		Level 3			Total
Securities
Assets:
Common Stocks
Biotechnology	$	265,268,318	$	4,761,391	$	—	¹	$	270,029,709

Total Value of Securities	$	733,509,359	$	91,695,640	$	—		$	825,204,999

¹The security that has been valued at zero on the "Schedule of investments" is considered to be Level 3 investments in this table.

During the year ended March 31, 2023, there were no transfers into or out of Level 3 investments. The Fund’s policy is to recognize transfers into or out of Level 3 investments based on fair value at the beginning of the reporting year.

A reconciliation of Level 3 investments is presented when the Fund has a significant amount of Level 3 investments at the beginning or end of the year in relation to the Fund’s net assets. Management has determined not to provide a reconciliation of Level 3 investments as the Level 3 investments were not considered significant to the Fund’s net assets at the beginning or

Table of Contents

end of the year. Management has determined not to provide additional disclosure on Level 3 inputs since the Level 3 investments were not considered significant to the Fund’s net assets at the end of the year.

4. Dividend and Distribution Information

Income and long-term capital gain distributions are determined in accordance with federal income tax regulations, which may differ from US GAAP. Additionally, distributions from net gains on foreign currency transactions and net short-term gains on sales of investment securities are treated as ordinary income for federal income tax purposes. The tax character of dividends and distributions paid during the years ended March 31, 2023 and 2022 were as follows:

	Year ended
	3/31/23		3/31/22
Ordinary income	$	1,167,433	$	7,946,243
Long-term capital gains		74,625,081		46,619,401
Total	$	75,792,514	$	54,565,644

5. Components of Net Assets on a Tax Basis

As of March 31, 2023, the components of net assets on a tax basis were as follows:

Shares of beneficial interest	$	620,873,477
Undistributed ordinary income		3,695,545
Undistributed long-term capital gains		4,579,417
Unrealized appreciation (depreciation) of investments and foreign currencies		186,931,806
Net assets	$	816,080,245

The differences between book basis and tax basis components of net assets are primarily attributable to tax deferral of losses on wash sales and tax treatment of securities no longer considered passive foreign investment companies.

For financial reporting purposes, capital accounts are adjusted to reflect the tax character of permanent book/tax differences. Results of operations and net assets were not affected by these reclassifications. For the year ended March 31, 2023, the Fund had no reclassifications.

Table of Contents

was allocated across the Participants based on a weighted average of the respective net assets of each Participant. The Participants were permitted to borrow up to a maximum of one-third of their net assets under the Agreement. Each Participant was individually, and not jointly, liable for its particular advances, if any, under the line of credit. The line of credit available under the Agreement expired on October 31, 2022.

On October 31, 2022, the Fund, along with the other Participants, entered into an amendment to the Agreement for a $355,000,000 revolving line of credit to be used as described above. It operates in substantially the same manner as the original Agreement. Under the amendment to the Agreement, the Participants are charged an annual commitment fee of 0.15%, which is allocated across the Participants based on a weighted average of the respective net assets of each Participant. The line of credit available under the Agreement expires on October 30, 2023.

The Fund had no amounts outstanding as of March 31, 2023, or at any time during the year then ended.

8. Derivatives

US GAAP requires disclosures that enable investors to understand: (1) how and why an entity uses derivatives; (2) how they are accounted for; and (3) how they affect an entity’s results of operations and financial position.

Foreign Currency Exchange Contracts — The Fund may enter into foreign currency exchange contracts as a way of managing foreign exchange rate risk. The Fund may enter into these contracts to fix the US dollar value of a security that it has agreed to buy or sell for the period between the date the trade was entered into and the date the security is delivered and paid for. The Fund may also enter into these contracts to hedge the US dollar value of securities it already owns that are denominated in foreign currencies. In addition, the Fund may enter into these contracts to facilitate or expedite the settlement of portfolio transactions. The change in value is recorded as an unrealized gain or loss. When the contract is closed, a realized gain or loss is recorded equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed.

The use of foreign currency exchange contracts does not eliminate fluctuations in the underlying prices of the securities, but does establish a rate of exchange that can be achieved in the future. Although foreign currency exchange contracts limit the risk of loss due to an unfavorable change in the value of the hedged currency, they also limit any potential gain that might result should the value of the currency change favorably. In addition, the Fund could be exposed to risks if the counterparties to the contracts are unable to meet the terms of their contracts. The Fund’s maximum risk of loss from counterparty credit risk is the value of its currency exchanged with the counterparty. The risk is generally mitigated by having a netting arrangement between the Fund and the counterparty and by the posting of collateral by the counterparty to the Fund to cover the Fund’s exposure to the counterparty. No foreign currency exchange contracts were outstanding at March 31, 2023.

		Long Derivative Volume				Short Derivative Volume
Foreign currency exchange contracts (average notional value)		$	—			$	95,270

9. Securities Lending

The Fund, along with other funds in the Delaware Funds, may lend its securities pursuant to a security lending agreement (Lending Agreement) with The Bank of New York Mellon (BNY Mellon). At the time a security is loaned, the borrower must post collateral equal to the required percentage of the market value of the loaned security, including any accrued interest. The required percentage is: (1) 102% with respect to US securities and foreign securities that are denominated and payable in US dollars; and (2) 105% with respect to foreign securities. With respect to each loan, if on any business day the aggregate market value of securities collateral plus cash collateral held is less than the aggregate market value of the securities which are the subject of such loan, the borrower will be notified to provide additional collateral by the end of the following business day, which, together with the collateral already held, will be not less than the applicable initial collateral requirements for such security loan. If the aggregate market value of securities collateral and cash collateral held with respect to a security loan exceeds the applicable initial collateral requirement, upon the request of the borrower, BNY Mellon must return enough collateral to the borrower by the end of the following business day to reduce the value of the remaining collateral to the applicable initial collateral requirement for such security loan. As a result of the foregoing, the value of the collateral held with respect to a loaned security on any particular day, may be more or less than the value of the security on loan. The collateral percentage with respect to the market value of the loaned security is determined by the security lending agent.

Cash collateral received by the Fund is generally invested in an individual separate account. The investment guidelines permit each separate account to hold certain securities that would be considered eligible securities for a money market fund. Cash collateral received is generally invested in government securities; certain obligations issued by government sponsored enterprises; repurchase agreements collateralized by US Treasury securities; obligations issued by the central government of any Organization for Economic Cooperation and Development (OECD) country or its agencies, instrumentalities, or establishments; obligations of supranational organizations; commercial paper, notes, bonds, and other debt obligations; certificates of deposit, time deposits, and other bank obligations; certain money market funds; and

Table of Contents

asset-backed securities. The Fund can also accept US government securities and letters of credit (non-cash collateral) in connection with securities loans.

In the event of default or bankruptcy by the lending agent, realization and/or retention of the collateral may be subject to legal proceedings. In the event the borrower fails to return loaned securities and the collateral received is insufficient to cover the value of the loaned securities and provided such collateral shortfall is not the result of investment losses, the lending agent has agreed to pay the amount of the shortfall to the Fund or, at the discretion of the lending agent, replace the loaned securities. The Fund continues to record dividends or interest, as applicable, on the securities loaned and is subject to changes in value of the securities loaned that may occur during the term of the loan. The Fund has the right under the Lending Agreement to recover the securities from the borrower on demand. With respect to security loans collateralized by non-cash collateral, the Fund receives loan premiums paid by the borrower. With respect to security loans collateralized by cash collateral, the earnings from the collateral investments are shared among the Fund, the security lending agent, and the borrower. The Fund records security lending income net of allocations to the security lending agent and the borrower.

The Fund may incur investment losses as a result of investing securities lending collateral. This could occur if an investment in the collateral investment account defaulted or became impaired. Under those circumstances, the value of the Fund's cash collateral account may be less than the amount the Fund would be required to return to the borrowers of the securities and the Fund would be required to make up for this shortfall.

At the year ended March 31, 2023, the Fund had no securities out on loan.

10. Credit and Market Risk

The global outbreak of COVID-19 has resulted in travel restrictions, closed international borders, enhanced health screenings at ports of entry and elsewhere, disruption of and delays in healthcare service preparation and delivery, prolonged quarantines, cancellations, supply chain disruptions, and lower consumer demand, as well as general concern and uncertainty. The impact of COVID-19, and other infectious illness outbreaks that may arise in the future, could adversely affect the economies of many nations or the entire global economy, individual issuers and capital markets in ways that cannot necessarily be foreseen. In addition, the impact of infectious illnesses in emerging market countries may be greater due to generally less established healthcare systems. Public health crises caused by the COVID-19 outbreak may exacerbate other pre-existing political, social and economic risks in certain countries or globally. The duration of the outbreak, its full economic impact and ongoing effects at the macro-level and on individual businesses are unpredictable and may result in significant and prolonged effects on a Fund's performance.

Investments in equity securities in general are subject to market risks that may cause their prices to fluctuate over time. Fluctuations in the value of equity securities in which the Fund invests will cause the NAV of the Fund to fluctuate.

Notes to financial statements

Delaware Healthcare Fund

10. Credit and Market Risk (continued)

The Fund invests a significant portion of its assets in small companies and may be subject to certain risks associated with ownership of securities of such companies. Investments in small-sized companies may be more volatile than investments in larger companies for a number of reasons, which include limited financial resources or a dependence on narrow product lines.

Some countries in which the Fund may invest require governmental approval for the repatriation of investment income, capital, or the proceeds of sales of securities by foreign investors. In addition, if there is deterioration in a country’s balance of payments or for other reasons, a country may impose temporary restrictions on foreign capital remittances abroad.

The securities exchanges of certain foreign markets are substantially smaller, less liquid, and more volatile than the major securities markets in the US. Consequently, acquisition and disposition of securities by the Fund may be inhibited. In addition, a significant portion of the aggregate market value of equity securities listed on the major securities exchanges in emerging markets is held by a smaller number of investors. This may limit the number of shares available for acquisition or disposition by the Fund.

The Fund is a nondiversified fund that concentrates its investments in the healthcare industry and is subject to the risks associated with that industry. The value of the Fund’s shares will be affected by factors particular to the healthcare and related sectors (such as government regulation) and may fluctuate more widely than that of a fund that invests in a broad range of industries.

The Fund may invest up to 15% of its net assets in illiquid securities, which may include securities with contractual restrictions on resale, securities exempt from registration under Rule 144A promulgated under the Securities Act of 1933, as amended, and other securities which may not be readily marketable. The relative illiquidity of these securities may impair the Fund from disposing of them in a timely manner and at a fair price when it is necessary or desirable to do so. While maintaining oversight, the Board has delegated to DMC the day-to-day functions of determining whether individual securities are liquid for purposes of the Fund’s limitation on investments in illiquid securities. Securities eligible for resale pursuant to Rule 144A, which are determined to be liquid, are not subject to the Fund’s 15% limit on investments in illiquid securities. Rule 144A securities have been identified on the "Schedule of investments."

11. Contractual Obligations

The Fund enters into contracts in the normal course of business that contain a variety of indemnifications. The Fund's maximum exposure under these arrangements is unknown. However, the Fund has not had prior claims or losses pursuant to these contracts. Management has reviewed the Fund's existing contracts and expects the risk of loss to be remote.

12. New Regulatory Pronouncement

In October 2022, the Securities and Exchange Commission (SEC) adopted a rule and form amendments relating to tailored shareholder reports for mutual funds and ETFs; and fee information in investment company advertisements. The rule and form amendments will require mutual funds and ETFs to transmit streamlined shareholder reports that highlight key information to investors. The rule amendments will require that certain more in-depth information be made available online and available for delivery free of charge to investors on request. The amendments became effective in January 2023 and there is an 18-month transition period after the effective date of the amendment with a compliance date of July 2024.

13. Subsequent Events

Management has determined that no material events or transactions occurred subsequent to March 31, 2023, that would require recognition or disclosure in the Fund's financial statements.

We conducted our audits of these financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our procedures included confirmation of securities owned as of March 31, 2023 by correspondence with the custodian and transfer agents.

Board of trustees and officers addendum

Delaware Funds by Macquarie^®

A mutual fund is governed by a Board of Trustees (“Trustees”), which has oversight responsibility for the management of a fund’s business affairs. Trustees establish procedures and oversee and review the performance of the investment manager, the distributor, and others who perform services for the fund. The independent fund trustees, in particular, are advocates for shareholder interests. Each trustee has served in that capacity since he or she was elected to or appointed to the Board of Trustees, and will continue to serve until his or her retirement or the election of a new trustee in his or her place. The following is a list of the Trustees and Officers with certain background and related information.

Market review

Though the overwhelming trend was to the downside, there was significant volatility throughout the fiscal period ended March 31, 2023, as the markets tried to understand and price peak inflation and the corresponding aggressive US Federal Reserve moves juxtaposed against stubborn employment and wage and manufacturing data that had yet to roll over. Continued strength in these measures led the Fed to reiterate its higher-and-hold interest rate policy instead of pivoting to a more dovish stance. As labor markets remained tight, the talk of peak

inflation continued to be offset by the growing concern of a hard landing due to the stress of tighter financial conditions. As rates continued to move higher, housing affordability rolled over with mortgage rates more than doubling off their lows, causing affordability to sink precipitously. The downdraft continued as focus began to shift from the macroeconomic concerns to corporate earnings degradation and the ultimate impact on how earnings and earnings growth should be appropriately priced, given the new higher interest rate environment.

The final volatility-inducing event of the 12-month period occurred early in March 2023 when the banking sector came under intense scrutiny, particularly at regional banks, due to mismatches in assets and liabilities caused by the Fed’s aggressive tightening cycle. Though there were two bank casualties in the US, a contagion was averted when the Fed stepped in with the announcement of a new emergency liquidity facility while protecting the uninsured deposits at those institutions in need. All of this changed the narrative to the expectation of an aggressive Fed pivot, which provided a significant tailwind once again to the equity markets, particularly larger capitalization growth stocks.

Within the Fund

For the fiscal year ended March 31, 2023, Delaware Mid Cap Growth Equity Fund underperformed its benchmark, the Russell 2500 Growth Index. The Fund’s Institutional Class shares returned -27.05%. The Fund’s Class A shares returned -27.22% at net asset value and -31.41% at maximum offer price. These figures reflect all distributions reinvested. During the same period, the benchmark returned -10.35%. For complete, annualized performance of Delaware Mid Cap Growth Equity Fund, please see the table on page 5.

Following is a discussion about performance during the period from December 5, 2022 (when the firm’s current portfolio management team began serving as the investment manager for the Fund) to March 31, 2023.

With the litany of uncertainties presented in the macroeconomic environment, we remain vigilant in our fundamental research, maintaining a concentrated portfolio of profitable, lower-debt companies that we think can grow throughout a market and economic cycle. Sector overweight and underweight positions are primarily a by-product of bottom-up stock selection, with notable overweight positions in information technology (IT), communication services, consumer discretionary, and healthcare and notable underweight positions in industrials, materials, and financials. The portfolio had no exposure to the energy, utilities, and real estate sectors, all of which contributed to performance during the period we managed the Fund, while the overweight allocation to IT provided the largest relative sector contribution to outperformance.

IT remained the largest sector allocation in the Fund. Overweight to this outperforming sector was a positive; however, poor stock selection offset the overweight, resulting in negative relative performance to the benchmark during the period we managed the Fund. Monolithic Power Systems Inc., which designs, develops, and markets integrated power semiconductor and power delivery architecture solutions, was an overweight outperformer in the Fund’s portfolio for the period. It announced a revenue beat in the first quarter of 2023 and maintained guidance for the second quarter in line with Wall Street

Table of Contents

expectations, and we purchased the stock during the period.

Healthcare, the third-largest sector allocation in the benchmark and a notable overweight in the Fund, detracted from relative performance because of stock selection, which offset a minor contribution from the sector’s overweight allocation. A positive standout during the period we managed the Fund was West Pharmaceutical Services Inc., a leading manufacturer in the design and production of technologically advanced, high-quality, integrated containment and delivery systems for injectable medicines. We researched and followed West for several years, though had not been comfortable with the risk-reward potential given the valuation of the stock over time. The market pullback in 2022 gave us the valuation opportunity we were waiting for to initiate a position in the portfolio. West has deftly navigated the stepdown from its COVID-19-induced accelerated product demand while increasing production capacity and maintaining focus on product development that suits the needs of the new biologic therapies coming to market. We added incrementally to the position early in the first quarter of 2023 as the valuation multiple climbed back to pre-2022 levels by quarter end.

CoStar Group Inc., a real estate data, analytics, and online marketplace, was a significant relative detractor to performance during the reporting period in the industrials sector yet remained the second-largest position in the Fund. There is always a bit of handwringing when CoStar announces guidance for the upcoming year, and 2023 was no exception. The company guided well below consensus expectations due to its investments in expanding its revenue model into the residential real estate market with the launch of Homes.com, which is expected to roll out mid-year. We strongly believe that management can navigate into this market with the same, if not better, success as its launch of Apartments.com, which in the fourth quarter of 2022 announced net new bookings growth of more than 170% year over year. We held steady on our position size in the portfolio throughout the period.

The financials sector experienced tremendous pressure in the first quarter of 2023 as news of Silicon Valley Bank’s (SVB’s) tenuous capital situation came into focus with unexpected and alarming rapidity. Fears of contagion and potential bank runs became widespread within days, bringing the entirety of the financial sector down as bank capital structures were fully scrutinized. While we didn’t own SVB, we did have exposure to two regional banks that suffered at the hands of the market. Though First Republic Bank’s capital situation was much different than that of SVB, the market treated the stock in a similar fashion, selling off more than 80% in the quarter, leading First Republic to be the largest single relative detractor to performance within the portfolio for the quarter. We sold the name as judiciously as possible, as we believe the landscape for regional banks has elevated scrutiny, increased potential for unknown risks, and a higher likelihood for increased regulation.

The energy sector is just over a 5% allocation to the benchmark, and we continue to have no exposure in this sector, which contributed positive relative sector allocation performance during the period we managed the Fund. We remain wary of the business models within the energy sector, in which companies have tended to spend with reckless, cyclical abandon and not for the longer-term viability and profile of their businesses. Recently, however, there has been an interesting change in that dynamic, as shareholders have spoken, and managements have listened to

Portfolio management review

the desire for more capital discipline. We continue to research potential names for the Fund’s portfolio.

Finally, overweight allocations to both consumer discretionary and communication services, coupled with strong stock selection in each sector, were positive for the period we managed the Fund. No exposure to the underperforming real estate sector contributed to relative outperformance in the period, and our cash position was an incremental contributor for the Fund in the period.

Given the macro backdrop, the turmoil evident in the banking sector, and the volatility in the market, we remain measured in our portfolio management approach. We now believe that the coming recessionary environment may be more certain and prolonged than we once expected. We are keenly aware that stock prices may not accurately reflect the true intrinsic value nor potential growth opportunity of companies for a full market cycle. In this environment, we are focused on earnings risk while continuously mindful that the price you pay for a stock can provide opportunity for returns over time as well as a margin of safety in an environment full of uncertainties. We have uncovered many company-specific opportunities as we filter through the mid-cap growth universe with the lens of holding names for three to five years. The idea of reshoring is of particular interest to us now. The production problems of the pandemic only served to intensify the corporate trend to diversify supply chains. From an investment perspective, the word automation resonates with us, from manufacturing to transportation to delivery.

We continue to look for opportunities to invest in companies that we believe have sound capital structures and the ability to grow throughout business and economic cycles, not because of the cycle. These business models have a product or service that appears durable to us, coupled with capital structure and management teams that allow them to execute competitively in any market environment. We continue to seek opportunities in business and consumer technology, innovation in life sciences, the green energy revolution, and other areas that we think should continue to grow, regardless of the economic cycle. While stock picking is always key to our process and performance, we think it will be paramount in this environment as we seek to manage valuation risk in the Fund’s portfolio while investing in what we view as durable, secular growth companies.

Expense limitations were in effect for certain classes during some or all of the periods shown in the “Fund and benchmark performance” table. Expenses for each class are listed on the “Fund expense ratios” table on page 6. Performance would have been lower had expense limitations not been in effect.

Class A shares are sold with a maximum front-end sales charge of 5.75%, and have an annual distribution and service (12b-1) fee of 0.25% of average daily net assets. The Board has adopted a formula for calculating 12b-1 plan fees for the Fund’s Class A shares. The Fund’s Class A shares are currently subject to a blended 12b-1 fee equal to the sum of: (i) 0.10% of average daily net assets representing shares acquired prior to June 1, 1992, and (ii) 0.25% of average daily net assets representing shares acquired on or after June 1, 1992. All Class A shares currently bear 12b-1 fees at the same rate, the blended rate, currently 0.25% of average daily net

assets, based on the formula described above. This method of calculating Class A 12b-1 fees may be discontinued at the sole discretion of the Board. Performance for Class A shares, excluding sales charges, assumes that no front-end sales charge applied.

Class R shares are available only for certain retirement plan products. They are sold without a sales charge and have an annual 12b-1 fee of 0.50% of average daily net assets.

Institutional Class shares are not subject to a sales charge and are offered for sale exclusively to certain eligible investors. In addition, Institutional Class shares pay no 12b-1 fee.

Class R6 shares are available only to certain investors. In addition, Class R6 shares do not pay any service fees, sub-accounting fees, and/or sub-transfer agency fees to any brokers, dealers, or other financial intermediaries. Class R6 shares pay no 12b-1 fee.

Investments in small and/or medium-sized companies typically exhibit greater risk and higher volatility than larger, more established companies.

Risk is increased in a concentrated portfolio since it holds a limited number of securities with each investment having a greater effect on the overall performance.

Notes to financial statements

Delaware Mid Cap Growth Equity Fund

March 31, 2023

Delaware Group^® Equity Funds IV (Trust) is organized as a Delaware statutory trust and offers 10 series. These financial statements and the related notes pertain to Delaware Mid Cap Growth Equity Fund (formerly, Delaware Smid Cap Growth Fund) (Fund). Effective April 28, 2023, the name of Delaware Smid Cap Growth Fund changed to Delaware Mid Cap Growth Equity Fund. The Trust is an open-end investment company. The Fund is considered diversified under the Investment Company Act of 1940, as amended (1940 Act), and offers Class A, Class C, Class R, Institutional Class, and Class R6 shares. Class A shares are sold with a maximum front-end sales charge of 5.75%. There is no front-end sales charge when you purchase $1 million or more of Class A shares. However, if Delaware Distributors, L.P. (DDLP) paid your financial intermediary a commission on your purchase of $1 million or more of Class A shares, you will have to pay a Limited CDSC of 1.00% if you redeem these shares within the first 18 months after your purchase, unless a specific waiver of the Limited CDSC applies. Class C shares have no upfront sales charge, but are sold with a contingent deferred sales charge (CDSC) of 1.00%, which will be incurred if redeemed during the first 12 months. Class R, Institutional Class, and Class R6 shares are not subject to a sales charge and are offered for sale exclusively to certain eligible investors. In addition, Class R6 shares do not pay any service fees, sub-accounting fees, and/or sub-transfer agency fees to any brokers, dealers, or other financial intermediaries.

1. Significant Accounting Policies

Security Valuation — Equity securities and exchange-traded funds (ETFs), except those traded on the Nasdaq Stock Market LLC (Nasdaq), are valued at the last quoted sales price as of the time of the regular close of the New York Stock Exchange on the valuation date. Equity securities and ETFs traded on the Nasdaq are valued in accordance with the Nasdaq Official Closing Price, which may not be the last sales price. If, on a particular day, an equity security or ETF does not trade, the mean between the bid and the ask prices will be used, which approximates fair value. Open-end investment companies, other than ETFs, are valued at their published net asset value (NAV). Generally, other securities and assets for which market quotations are not readily available are valued at fair value as determined in good faith by the Fund’s valuation designee, Delaware Management Company (DMC). Subject to the oversight of the Trust’s Board of Trustees (Board), DMC, as valuation designee, has adopted policies and procedures to fair value securities for which market quotations are not readily available consistent with the requirements of Rule 2a-5 under the 1940 Act. In determining whether market quotations are readily available or fair valuation will be used, various factors will be taken into consideration, such as market closures or suspension of trading in a security. Restricted securities and private placements are valued at fair value.

the requisite distributions to shareholders. The Fund evaluates tax positions taken or expected to be taken in the course of preparing the Fund’s tax returns to determine whether the tax positions are “more-likely-than-not” of being sustained by the applicable tax authority. Tax positions not deemed to meet the “more-likely-than-not” threshold are recorded as a tax benefit or expense in the current year. Management has analyzed the Fund’s tax positions taken or expected to be taken on the Fund’s federal income tax returns through the year ended March 31, 2023, and for all open tax years (years ended March 31, 2020 – March 31, 2022), and has concluded that no provision for federal income tax is required in the Fund’s financial statements. If applicable, the Fund recognizes interest accrued on unrecognized tax benefits in interest expense and penalties in “Other” on the “Statement of operations.” During the year ended March 31, 2023, the Fund did not incur any interest or tax penalties.

Class Accounting — Investment income, common expenses, and realized and unrealized gain (loss) on investments are allocated to the various classes of the Fund on the basis of daily net assets of each class. Distribution expenses relating to a specific class are charged directly to that class. Class R6 shares will not be allocated any expenses related to service fees, sub-accounting fees, and/or sub-transfer agency fees paid to brokers, dealers, or other financial intermediaries.

Other — Expenses directly attributable to the Fund are charged directly to the Fund. Other expenses common to various funds within the Delaware Funds by Macquarie^® (Delaware Funds) are generally allocated among such funds on the basis of average net assets. Management fees and certain other expenses are paid monthly. Security transactions are recorded on the date the securities are purchased or sold (trade date) for financial reporting purposes. Costs used in calculating realized gains and losses on the sale of investment securities are those of the specific securities sold. Dividend income is recorded on the ex-dividend date and interest income is recorded on an accrual basis. Taxable non-cash dividends are recorded as dividend income. Income and capital gain distributions from any investment companies (Underlying Funds) in which the Fund invests are recorded on the ex-dividend date. Distributions received from investments in real estate investment trusts (REITs) are recorded as dividend income on the ex-dividend date, subject to reclassification upon notice of the character of such distributions by the issuer. The Fund declares and pays dividends from net investment income and distributions from net realized gain on investments, if any, at least annually. The Fund may distribute more frequently, if necessary for tax purposes. Dividends and distributions, if any, are recorded on the ex-dividend date.

2. Investment Management, Administration Agreements, and Other Transactions with Affiliates

In accordance with the terms of its investment management agreement, the Fund pays DMC, a series of Macquarie Investment Management Business Trust and the investment manager, an annual fee which is calculated daily and paid monthly at the rates of 0.75% on the first $500 million of average daily net assets of the Fund, 0.70% on the next $500 million, 0.65% on the next $1.5 billion, and 0.60% on average daily net assets in excess of $2.5 billion.

DMC entered into Sub-Advisory Agreements on behalf of the Fund with Macquarie Funds Management Hong Kong Limited and Macquarie Investment Management Global Limited, each of which is an affiliate of DMC (“Affiliated Sub-Advisor”). Pursuant to the terms of the relevant Sub-Advisory Agreement, the investment sub-advisory fee is paid by DMC to each Affiliated Sub- Advisor based on the extent to which an Affiliated Sub-Advisor provides services to the Fund.

DIFSC is also the transfer agent and dividend disbursing agent of the Fund. For these services, DIFSC’s fees are calculated daily and paid monthly, based on the aggregate daily net assets of the retail funds within the Delaware Funds at the following annual rates: 0.014% of the first $20 billion; 0.011% of the next $5 billion; 0.007% of the next $5 billion; 0.004% of the next $20 billion; 0.002% of the next $25 billion; and 0.0015% of average daily net assets in excess of $75 billion. The fees payable to DIFSC under the shareholder services agreement described above are allocated among all retail funds in the Delaware Funds on a relative NAV basis. This amount is included on the “Statement of operations” under “Dividend disbursing and transfer agent fees and expenses.” For the year ended March 31, 2023, the Fund paid $1,193,870 for these services. Pursuant to a sub-transfer agency agreement between DIFSC and BNY Mellon Investment Servicing (US) Inc. (BNYMIS), BNYMIS provides certain sub-transfer agency

services to the Fund. Sub-transfer agency fees are paid by the Fund and are also included on the “Statement of operations” under “Dividend disbursing and transfer agent fees and expenses.” The fees that are calculated daily and paid as invoices are received on a monthly or quarterly basis.

Pursuant to a distribution agreement and distribution plan, the Fund pays DDLP, the distributor and an affiliate of DMC, an annual 12b-1 fee of 0.25%, 1.00%, and 0.50% of the average daily net assets of the Class A, Class C, and Class R shares, respectively. The Board has adopted a formula for calculating 12b-1 fees for the Fund’s Class A shares. The total 12b-1 fees to be paid by Class A shareholders of the Fund will be the sum of: (i) 0.10% of average daily net assets representing shares acquired prior to June 1, 1992, and (ii) 0.25% of average daily net assets representing shares acquired on or after June 1, 1992. All Class A shareholders bear 12b-1 fees at the same rate, the blended rate, currently 0.25% of average daily net assets, based upon the allocation described above. This method of calculating Class A 12b-1 fees may be discontinued at the sole discretion of the Board. The fees are calculated daily and paid monthly. Institutional Class and Class R6 shares do not pay a 12b-1 fee.

For the year ended March 31, 2023, DDLP earned $42,474 for commissions on sales of the Fund’s Class A shares. For the year ended March 31, 2023, DDLP received gross CDSC commissions of $75,586 and $5,375 on redemptions of the Fund’s Class A and Class C shares, respectively, and these commissions were entirely used to offset upfront commissions previously paid by DDLP to broker/dealers on sales of those shares.

Cross trades for the year ended March 31, 2023 were executed by the Fund pursuant to procedures adopted by the Board designed to ensure compliance with Rule 17a-7 under the 1940 Act. Cross trading is the buying or selling of portfolio securities between funds of investment companies, or between a fund of an investment company and another entity, that are or could be considered affiliates by virtue of having a common investment advisor (or affiliated

investment advisors), common directors/trustees and/or common officers. At its regularly scheduled meetings, the Board reviews such transactions for compliance with the procedures adopted by the Board. Pursuant to these procedures, for the year ended March 31, 2023, the Fund engaged in Rule 17a-7 securities sales of $15,384,785 which resulted in realized gain of $3,812,734. The Fund did not engage in Rule 17a-7 securities purchases for the year ended March 31, 2023.

3. Investments

For the year ended March 31, 2023, the Fund made purchases and sales of investment securities other than short-term investments as follows:

Purchases		$	2,503,299,861
Sales			3,224,973,280

Table of Contents

Cost of investments	$	1,469,190,556
Aggregate unrealized appreciation of investments	$	95,630,348
Aggregate unrealized depreciation of investments		(67,316,549	)
Net unrealized appreciation of investments	$	28,313,799

US GAAP defines fair value as the price that the Fund would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date under current market conditions. A three-level hierarchy for fair value measurements has been established based upon the transparency of inputs to the valuation of an asset or liability. Inputs may be observable or unobservable and refer broadly to the assumptions that market participants would use in pricing the asset or liability. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the reporting entity’s own assumptions about the assumptions that market participants would use in pricing the asset or liability based on the best information available under the circumstances. The Fund’s investment in its entirety is assigned a level based upon the observability of the inputs which are significant to the overall valuation. The three-level hierarchy of inputs is summarized as follows:

Level 1 – Inputs are quoted prices in active markets for identical investments. (Examples: equity securities, open-end investment companies, futures contracts, and exchange-traded options contracts)

Level 2 – Other observable inputs, including, but not limited to: quoted prices for similar assets or liabilities in markets that are active, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks, and default rates) or other market-corroborated inputs. (Examples: debt securities, government securities, swap contracts, foreign currency exchange contracts, foreign securities utilizing international fair value pricing, broker-quoted securities, and fair valued securities)

Level 3 – Significant unobservable inputs, including the Fund’s own assumptions used to determine the fair value of investments. (Examples: broker-quoted securities and fair valued securities)

3. Investments (continued)

upon current market prices of securities that are comparable in coupon, rating, maturity, and industry. The derived value of a Level 3 investment may not represent the value which is received upon disposition and this could impact the results of operations.

The following table summarizes the valuation of the Fund’s investments by fair value hierarchy levels as of March 31, 2023:

	Level 1
Securities
Assets:
Common Stocks	$	1,492,467,019
Short-Term Investments		5,037,336
Total Value of Securities	$	1,497,504,355

4. Dividend and Distribution Information

Income and long-term capital gain distributions are determined in accordance with federal income tax regulations, which may differ from US GAAP. Additionally, distributions from net short-term gains on sales of investment securities are treated as ordinary income for federal income tax purposes. The tax character of dividends and distributions paid during the years ended March 31, 2023 and 2022 were as follows:

	Year ended
		3/31/23		3/31/22
Ordinary income	$	—	$	221,884,395
Long-term capital gains		271,423,392		724,960,952
Total	$	271,423,392	$	946,845,347

Table of Contents

5. Components of Net Assets on a Tax Basis

As of March 31, 2023, the components of net assets on a tax basis were as follows:

Shares of beneficial interest	$	2,416,950,500
Qualified late year loss deferrals		(2,557,631	)
Capital loss carryforwards		(942,974,283	)
Unrealized appreciation (depreciation) of investments		28,313,799
Net assets	$	1,499,732,385

The differences between book basis and tax basis components of net assets are primarily attributable to tax deferral of losses on wash sales.

Qualified late year losses represent ordinary losses realized from January 1, 2023 through March 31, 2023 and capital losses realized from November 1, 2022 through March 31, 2023, that in accordance with federal income tax regulations, the Fund has elected to defer and treat as having arisen in the following fiscal year.

For financial reporting purposes, capital accounts are adjusted to reflect the tax character of permanent book/tax differences. Reclassifications are primarily due to tax treatment of net operating losses. Results of operations and net assets were not affected by these reclassifications. For the year ended March 31, 2023, the adjustments were to increase total distributable earnings and decrease paid-in capital in excess of par by $22,240,189.

At March 31, 2023, the Fund has capital loss carryforwards available to offset future realized capital gains as follows:

	Loss carryforward character
	Short-term		Long-term		Total
$	482,129,162	$	460,845,121	$	942,974,283

7. Line of Credit

The Fund, along with certain other funds in the Delaware Funds (Participants), was a participant in a $355,000,000 revolving line of credit (Agreement) intended to be used for temporary or emergency purposes as an additional source of liquidity to fund redemptions of investor shares. Under the Agreement, the Participants were charged an annual commitment fee of 0.15%, which was allocated across the Participants based on a weighted average of the respective net assets of each Participant. The Participants were permitted to borrow up to a maximum of one-third of their net assets under the Agreement. Each Participant was individually, and not jointly, liable for its particular advances, if any, under the line of credit. The line of credit available under the Agreement expired on October 31, 2022.

The Fund had no amounts outstanding as of March 31, 2023, or at any time during the year then ended.

8. Securities Lending

Table of Contents

Notes to financial statements
Delaware Mid Cap Growth Equity Fund

8. Securities Lending (continued)

The Fund may incur investment losses as a result of investing securities lending collateral. This could occur if an investment in the collateral investment account defaulted or became impaired. Under those circumstances, the value of the Fund’s cash collateral account may be less than the amount the Fund would be required to return to the borrowers of the securities and the Fund would be required to make up for this shortfall.

At the year ended March 31, 2023, the Fund had no securities out on loan.

9. Credit and Market Risk

Table of Contents

infectious illnesses in emerging market countries may be greater due to generally less established healthcare systems. Public health crises caused by the COVID-19 outbreak may exacerbate other pre-existing political, social and economic risks in certain countries or globally. The duration of the outbreak, its full economic impact and ongoing effects at the macro-level and on individual businesses are unpredictable and may result in significant and prolonged effects on a Fund’s performance.

The Fund invests in growth stocks (such as those in the technology sector), which reflect projections of future earnings and revenue. These prices may rise or fall dramatically depending on whether those projections are met. These companies’ stock prices may be more volatile, particularly over the short term.

The Fund invests a significant portion of its assets in small- and mid-sized companies and may be subject to certain risks associated with ownership of securities of such companies. Investments in small- or mid-sized companies may be more volatile than investments in larger companies for a number of reasons, which include limited financial resources or a dependence on narrow product lines.

The Fund invests in REITs and is subject to the risks associated with that industry. If the Fund holds real estate directly or receives rental income directly from real estate holdings, its tax status as a regulated investment company may be jeopardized. There were no direct real estate holdings during the year ended March 31, 2023. The Fund’s REIT holdings are also affected by interest rate changes, particularly if the REITs it holds use floating rate debt to finance their ongoing operations.

The Fund may invest up to 15% of its net assets in illiquid securities, which may include securities with contractual restrictions on resale, securities exempt from registration under Rule 144A promulgated under the Securities Act of 1933, as amended, and other securities which may not be readily marketable. The relative illiquidity of these securities may impair the Fund from disposing of them in a timely manner and at a fair price when it is necessary or desirable to do so. While maintaining oversight, the Board has delegated to DMC the day-to-day functions of determining whether individual securities are liquid for purposes of the Fund’s limitation on investments in illiquid securities. Securities eligible for resale pursuant to Rule 144A, which are determined to be liquid, are not subject to the Fund’s 15% limit on investments in illiquid securities. As of March 31, 2023, there were no Rule 144A securities held by the Fund.

10. Contractual Obligations

The Fund enters into contracts in the normal course of business that contain a variety of indemnifications. The Fund’s maximum exposure under these arrangements is unknown.

Table of Contents

Notes to financial statements
Delaware Mid Cap Growth Equity Fund

10. Contractual Obligations (continued)

However, the Fund has not had prior claims or losses pursuant to these contracts. Management has reviewed the Fund’s existing contracts and expects the risk of loss to be remote.

11. New Regulatory Pronouncement

12. Subsequent Events

Effective April 28, 2023, the name of Delaware Smid Cap Growth Fund changed to Delaware Mid Cap Growth Equity Fund.

Management has determined that no other material events or transactions occurred subsequent to March 31, 2023, that would require recognition or disclosure in the Fund’s financial statements.

Report of independent
registered public accounting firm

To the Board of Trustees of Delaware Group^® Equity Funds IV and Shareholders of Delaware Mid Cap Growth Equity Fund

Opinion on the Financial Statements

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Delaware Mid Cap Growth Equity Fund (formerly, Delaware Smid Cap Growth Fund) (one of the funds constituting Delaware Group® Equity Funds IV, referred to hereafter as the “Fund”) as of March 31, 2023, the related statement of operations for the year ended March 31, 2023, the statements of changes in net assets for each of the two years in the period ended March 31, 2023, including the related notes, and the financial highlights for each of the five years in the period ended March 31, 2023 (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund as of March 31, 2023, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period ended March 31, 2023 and the financial highlights for each of the five years in the period ended March 31, 2023 in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our procedures included confirmation of securities owned as of March 31, 2023 by correspondence with the custodian, transfer agents and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

Significant Fund event

Market review

Positive returns for the market during the stub period of early December 2022 through March 31, 2023 were a welcome relief from the sharp market correction in calendar year 2022. After fizzling out at the end of December, small-cap growth stocks staged a strong rally at the beginning of calendar 2023 coincident with a move downward in the US government 10-year Treasury bond rate.

The Fund's strategy broadened during the period we managed it to include more exposure to what we view as attractive growth companies in sectors such as industrials, communication services, financials, and energy.

Portfolio management review

Delaware Small Cap Growth Fund

The rally lasted through early February, which also corresponded with a reversal in the 10-year Treasury. The same issues that caused the weakness in 2022 surfaced in February as the US Federal Reserve’s determination to snuff out inflation led to interest rate hikes in February and March, and the consequent recession fears raised alarm over earnings for 2023. The collapse of Silicon Valley Bank and the contagion it caused throughout the banking system was the final blow. The latter issue had a more pronounced impact on small-cap stocks, which resulted in underperformance versus their mid-cap and large-cap peers. Small-cap growth stocks, however, fared better than small-cap value stocks, which have a heavier concentration of financial companies.

Within the Fund

For the fiscal year ended March 31, 2023, Delaware Small Cap Growth Fund underperformed its benchmark, the Russell 2000 Growth Index. The Fund’s Institutional Class shares returned -25.58%. The Fund’s Class A shares returned -25.76% at net asset value and -30.02% at maximum offer price. These figures reflect all distributions reinvested. During the same period, the benchmark returned -10.60%. For complete, annualized performance of Delaware Small Cap Growth Fund, please see the table on page 4.

The strongest sector gains versus the benchmark included consumer discretionary, technology, financials, and consumer staples.

The Fund strategy broadened during the period we managed it, to include more exposure to what we view as attractive growth companies in sectors such as industrials, communication services, financials, and energy. Accordingly, the number of holdings increased to a level above 50. These moves were designed to dampen some of the excess volatility of the portfolio while maintaining attractive growth dynamics. Funding for changes in the portfolio came from a few mid-cap holdings as well as reductions in the weightings of other stocks.

On Holding AG, Wingstop Inc., Floor & Décor Holdings Inc., and Boot Barn Inc. led gains in the consumer discretionary sector. Consumer spending has remained quite resilient during this period of rising interest rates and inflation, with market share winners like those mentioned above thriving. We reduced a substantial overweight in this sector somewhat to reflect the strong performance of the stocks in the face of rising concerns over the economy.

In consumer staples, cosmetic company e.l.f. Beauty Inc. has been the standout in the Fund and remains a top holding. The technology sector has also performed well as earnings for growth companies have held up much better than the cyclicals. Leading contributors in the recent period included Lattice Semiconductor Corp. and DoubleVerify Holdings Inc. Cybersecurity software and communications equipment holdings have been added to the sector.

The industrials sector performance was slightly negative during the period that we managed the Fund, as investor reaction toward cyclical sectors seemed to sway with each economic datapoint. The portfolio was underweight industrials, which was the main reason for slight sector underperformance.

Clean Harbors Inc., a provider of environmental remediation and industrial waste management services, is a new position in the Fund and was a strong contributor for the period we managed the Fund.

Healthcare continued its struggles to separate itself from macroeconomic pressures. While there were some improvements in procedure volumes, inflation, and labor pressures, each remained more of a headwind than hoped this far out from the worst of COVID-19. In addition, financing fears are accelerating, which put pressure on the less profitable segments, like biotech. The Fund’s portfolio underperformed the healthcare sector due to poor stock selection on a couple of holdings. In particular, medical device manufacturer Inari Medical Inc. was a significant detractor as it faced competitive and valuation concerns.

*The benchmark lifetime returns are calculated using the Fund’s inception date.

**Total return for the report period presented in the table differs from the return in “Financial highlights.” The total return presented in the above table is calculated based on the net asset value (NAV) at which shareholder transactions were processed. The total return presented in “Financial highlights” is calculated in the same manner but also takes into account certain adjustments that are necessary under US generally accepted accounting principles required in the annual report.

Class A shares are sold with a maximum front-end sales charge of 5.75%, and have an annual distribution and service (12b-1) fee of 0.25% of average daily net assets. Performance for Class A shares, excluding sales charges, assumes that no front-end sales charge applied.

Table of Contents

Class R shares are available only for certain retirement plan products. They are sold without a sales charge and have an annual 12b-1 fee of 0.50% of average daily net assets.

Institutional Class shares are not subject to a sales charge and are offered for sale exclusively to certain eligible investors. In addition, Institutional Class shares pay no (12b-1) fee.

Investments in small and/or medium-sized companies typically exhibit greater risk and higher volatility than larger, more established companies.

Risk is increased in a concentrated portfolio since it holds a limited number of securities with each investment having a greater effect on the overall performance.

Actual expenses

Hypothetical example for comparison purposes

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads), redemption fees, or exchange fees. Therefore, the second section of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. The Fund's expenses shown in the table reflect fee waivers in effect and assume reinvestment of all dividends and distributions.

Notes to financial statements

Delaware Small Cap Growth Fund

March 31, 2023

Delaware Group^®Equity Funds IV (Trust) is organized as a Delaware statutory trust and offers 10 series. These financial statements and the related notes pertain to Delaware Small Cap Growth Fund (Fund). The Trust is an open-end investment company. The Fund is considered diversified under the Investment Company Act of 1940, as amended (1940 Act), and offers Class A, Class C, Class R, and Institutional Class shares. Class A shares are sold with a maximum front-end sales charge of 5.75%. There is no front-end sales charge when you purchase $1 million or more of Class A shares. However, if Delaware Distributors, L.P. (DDLP) paid your financial intermediary a commission on your purchase of $1 million or more of Class A shares, you will have to pay a Limited CDSC of 1.00% if you redeem these shares within the first 18 months after your purchase, unless a specific waiver of the Limited CDSC applies. Class C shares have no upfront sales charge, but are sold with a contingent deferred sales charge (CDSC) of 1.00%, which will be incurred if redeemed during the first 12 months. Class R and Institutional Class shares are not subject to a sales charge and are offered for sale exclusively to certain eligible investors.

1. Significant Accounting Policies

Security Valuation — Equity securities and exchange-traded funds (ETFs), except those traded on the Nasdaq Stock Market LLC (Nasdaq), are valued at the last quoted sales price as of the time of the regular close of the New York Stock Exchange on the valuation date. Equity securities and ETFs traded on the Nasdaq are valued in accordance with the Nasdaq Official Closing Price, which may not be the last sales price. If, on a particular day, an equity security or ETF does not trade, the mean between the bid and the ask prices will be used, which approximates fair value. Open-end investment companies, other than ETFs, are valued at their published net asset value (NAV). Generally, other securities and assets for which market quotations are not readily available are valued at fair value as determined in good faith by the Fund's valuation designee, Delaware Management Company (DMC). Subject to the oversight of the Trust's Board of Trustees (Board), DMC, as valuation designee, has adopted policies and procedures to fair value securities for which market quotations are not readily available consistent with the requirements of Rule 2a-5 under the 1940 Act. In determining whether market quotations are readily available or fair valuation will be used, various factors will be taken into consideration, such as market closures or suspension of trading in a security. Restricted securities and private placements are valued at fair value.

Federal Income Taxes — No provision for federal income taxes has been made as the Fund intends to continue to qualify for federal income tax purposes as a regulated investment company under Subchapter M of the Internal Revenue Code of 1986, as amended, and make the requisite distributions to shareholders. The Fund evaluates tax positions taken or expected to be taken in the course of preparing the Fund's tax returns to determine whether the tax positions

Table of Contents

are “more-likely-than-not” of being sustained by the applicable tax authority. Tax positions not deemed to meet the “more-likely-than-not” threshold are recorded as a tax benefit or expense in the current year. Management has analyzed the Fund's tax positions taken or expected to be taken on the Fund's federal income tax returns through the year ended March 31, 2023, and for all open tax years (years ended March 31, 2020 – March 31, 2022), and has concluded that no provision for federal income tax is required in the Fund's financial statements. If applicable, the Fund recognizes interest accrued on unrecognized tax benefits in interest expense and penalties in “Other” on the “Statement of operations.” During the year ended March 31, 2023, the Fund did not incur any interest or tax penalties.

Other — Expenses directly attributable to the Fund are charged directly to the Fund. Other expenses common to various funds within the Delaware Funds by Macquarie^®(Delaware Funds) are generally allocated among such funds on the basis of average net assets. Management fees and certain other expenses are paid monthly. Security transactions are recorded on the date the securities are purchased or sold (trade date) for financial reporting purposes. Costs used in calculating realized gains and losses on the sale of investment securities are those of the specific securities sold. Dividend income is recorded on the ex-dividend date and interest income is recorded on an accrual basis. Income and capital gain distributions from any investment companies (Underlying Funds) in which the Fund invests are recorded on the ex-dividend date. Distributions received from investments in real estate investment trusts (REITs) are recorded as dividend income on the ex-dividend date, subject to reclassification upon notice of the character of such distributions by the issuer. The Fund declares and pays dividends from net investment income and distributions from net realized gain on investments, if any, at least annually. The Fund may distribute more frequently, if necessary for tax purposes. Dividends and distributions, if any, are recorded on the ex-dividend date.

2. Investment Management, Administration Agreements, and Other Transactions with Affiliates

In accordance with the terms of its investment management agreement, the Fund pays DMC, a series of Macquarie Investment Management Business Trust and the investment manager, an annual fee which is calculated daily and paid monthly at the rates of 0.75% on the first $500 million of average daily net assets of the Fund, 0.70% on the next $500 million, 0.65% on the next $1.5 billion, and 0.60% on average daily net assets in excess of $2.5 billion.

DMC has contractually agreed to waive all or a portion of its investment advisory fees and/or pay/reimburse expenses (excluding any distribution and service (12b-1) fees, taxes, interest, acquired fund fees and expenses, short sale dividend and interest expenses, brokerage fees, certain insurance costs, and non-routine expenses or costs, including, but not limited to, those relating to reorganizations, litigation, conducting shareholder meetings, and liquidations), in order to prevent total annual fund operating expenses from exceeding 0.89% of the Fund's average daily net assets from January 31, 2023 through March 31, 2023.* Prior to January 31, 2023, DMC contractually agreed to waive all or a portion of its management fee and/or pay/reimburse expenses in order to prevent total annual fund operating expenses from exceeding 1.05% of the Fund's average daily net assets. These waivers and reimbursements may only be terminated by agreement of DMC and the Fund. The waivers and reimbursements are accrued daily and received monthly.

Table of Contents

above are allocated among all retail funds in the Delaware Funds on a relative NAV basis. This amount is included on the “Statement of operations” under “Dividend disbursing and transfer agent fees and expenses.” For the year ended March 31, 2023, the Fund paid $92,583 for these services. Pursuant to a sub-transfer agency agreement between DIFSC and BNY Mellon Investment Servicing (US) Inc. (BNYMIS), BNYMIS provides certain sub-transfer agency services to the Fund. Sub-transfer agency fees are paid by the Fund and are also included on the “Statement of operations” under “Dividend disbursing and transfer agent fees and expenses.” The fees are calculated daily and paid as invoices are received on a monthly or quarterly basis.

As provided in the investment management agreement, the Fund bears a portion of the cost of certain resources shared with DMC, including the cost of internal personnel of DMC and/or its affiliates that provide legal and regulatory reporting services to the Fund. For the year ended March 31, 2023, the Fund paid $4,366 for internal legal and regulatory reporting services provided by DMC and/or its affiliates’ employees. This amount is included on the “Statement of operations” under “Legal fees.” For the year ended March 31, 2023, DDLP earned $5,024 for commissions on sales of the Fund’s Class A shares. For the year ended March 31, 2023, DDLP received gross CDSC commissions of $21 and $888 on redemptions of the Fund’s Class A and Class C shares, respectively, and these commissions were entirely used to offset upfront commissions previously paid by DDLP to broker/dealers on sales of those shares.

In addition to the management fees and other expenses of the Fund, the Fund indirectly bears the investment management fees and other expenses of any Underlying Funds, including ETFs, in which it invests. The amount of these fees and expenses incurred indirectly by the Fund will vary based upon the expense and fee levels of any Underlying Funds and the number of shares that are owned of any Underlying Funds at different times.

*The aggregate contractual waiver period covering this report is from January 31, 2023 through July 29, 2024.

A reconciliation of Level 3 investments is presented when the Fund has a significant amount of Level 3 investments at the beginning or end of the year in relation to the Fund's net assets. During the year ended March 31, 2023, there were no Level 3 investments.

4. Dividend and Distribution Information

Income and long-term capital gain distributions are determined in accordance with federal income tax regulations, which may differ from US GAAP.

The tax character of dividends and distributions paid during the years ended March 31, 2023 and 2022 were as follows:

	Year ended
	3/31/23		3/31/22
Ordinary income	$	—	$	12,143,076

5. Components of Net Assets on a Tax Basis

As of March 31, 2023, the components of net assets on a tax basis were as follows:

Shares of beneficial interest	$	196,584,336
Qualified late year loss deferrals		(251,302	)
Capital loss carryforwards		(81,203,216	)
Net unrealized appreciation of investments and foreign currencies		4,207,861
Net assets	$	119,337,679

The differences between book basis and tax basis components of net assets are primarily attributable to tax deferral of losses on wash sales.

For federal income tax purposes, capital loss carryforwards may be carried forward and applied against future capital gains. At March 31, 2023, the Fund has capital loss carryforwards available to offset future realized capital gains as follows:

on whether those projections are met. These companies’ stock prices may be more volatile, particularly over the short term.

The Fund may invest up to 15% of its net assets in illiquid securities, which may include securities with contractual restrictions on resale, securities exempt from registration under Rule 144A promulgated under the Securities Act of 1933, as amended, and other securities which may not be readily marketable. The relative illiquidity of these securities may impair the Fund from disposing of them in a timely manner and at a fair price when it is necessary or desirable to do so. While maintaining oversight, the Board has delegated to DMC, the day-to-day functions of determining whether individual securities are liquid for purposes of the Fund's limitation on investments in illiquid securities. Securities eligible for resale pursuant to Rule 144A, which are determined to be liquid, are not subject to the Fund's 15% limit on investments in illiquid securities. As of March 31, 2023, there were no Rule 144A securities held by the Fund.

10. Contractual Obligations

11. Subsequent Events

Management has determined that no material events or transactions occurred subsequent to March 31, 2023, that would require recognition or disclosure in the Fund's financial statements.

Report of independent

registered public accounting firm

To the Board of Trustees of Delaware Group^®Equity Funds IV and Shareholders of Delaware Small Cap Growth Fund

Opinion on the Financial Statements

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Delaware Small Cap Growth Fund (one of the funds constituting Delaware Group^®Equity Funds IV, referred to hereafter as the “Fund”) as of March 31, 2023, the related statement of operations for the year ended March 31, 2023, the statements of changes in net assets for each of the two years in the period ended March 31, 2023, including the related notes, and the financial highlights for each of the five years in the period ended March 31, 2023 (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund as of March 31, 2023, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period ended March 31, 2023 and the financial highlights for each of the five years in the period ended March 31, 2023 in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our procedures included confirmation of securities owned as of March 31, 2023 by correspondence with the custodian, transfer agents and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.
