Portfolio Management Discussion \| 4/30/25

***Note to Stockholders: Effective April 1, 2025, Victory Capital Management Inc. ("Victory Capital") serves as the Fund's investment adviser. See Note 8 to the Financial Statements for more information.***

On May 6, 2025, the Board of Directors of the Fund approved a plan of liquidation of the Fund. The liquidation pursuant to the plan will be submitted to Fund stockholders for approval at a Special Meeting. The Board recommends that stockholders of the Fund vote for the liquidation of the Fund at the Special Meeting. The Fund has submitted a proxy statement to the U.S. Securities and Exchange Commission with respect to the proposal to liquidate the Fund. Copies of the Fund's proxy statement will also be mailed to each stockholder of record of the Fund. Stockholders are advised to read the Fund's proxy statement when it is available because it will contain important information.

In the following interview, John (Jake) Crosby Van Roden III discusses the factors that affected the performance of the Pioneer Municipal High Income Opportunities Fund, Inc. during the 12-month period ended April 30, 2025. Mr. Van Roden, Managing Director and Director of Municipals at Victory Capital is responsible for the day-to-day management of the Fund.

| **Q** | **How did the Fund perform during the year ended April 30, 2025?** |
| **A** | Pioneer Municipal High Income Opportunities Fund, Inc. returned 3.41% at net asset value (NAV) and 12.07% at market price during the 12-month period ended April 30, 2025. During the same 12-month period, the Fund's benchmarks, the Bloomberg US Municipal High Yield Bond Index and the Bloomberg Municipal Bond Index, returned 4.35% and 1.66% at NAV, respectively. The Bloomberg US Municipal High Yield Bond Index is an unmanaged measure of the performance of lower rated municipal bonds, while the Bloomberg Municipal Bond Index is an unmanaged measure of the performance of investment-grade municipal bonds. Unlike the Fund, the two indices do not use leverage. While the use of leverage increases investment opportunity, it also increases investment risk. |
|  | During the same 12-month period, the average return at NAV of the 28 closed end funds in Morningstar's Closed End High Yield Municipal category (which may or may not be leveraged) was 3.10%, and the average return at market price of the closed-end funds within the same Morningstar category was 12.13%. The shares of the Fund were selling at a 4.79% discount to NAV on |

|  | April 30, 2025. Comparatively, the shares of the Fund were selling at a 12.14% discount to NAV on April 30, 2024. On April 30, 2025, the standardized 30-day SEC yield of the Fund's shares was 4.77%.\* |
| **Q** | **Which of the Fund's investment strategies contributed positively to performance over the period?** |
| **A** | The Fund's primary objective is to provide a high level of current income to shareholders, exempt from regular federal income tax. The Fund's income paying ability was maintained during the period through a series of thematic repositioning trades. Credit selection, was a key positive contributor to the Fund's performance. The Fund was able to sell certain lower coupon bonds and reinvest the proceeds of those sales into higher coupon bonds. In addition, the call structure of the portfolio was enhanced as short call bonds were sold and reinvested in municipal bonds with longer call dates. The Fund's credit profile favored a bias to lower quality, higher yielding securities. |
| **Q** | **Which investment strategies detracted from the Fund's benchmark-relative performance results during the 12-month period ended April 30, 2025?** |
| **A** | The Fund carries leveraged exposure to the municipal bond market. The Fund disposed of relatively illiquid tobacco MSA bonds, including zero coupon bonds, and reinvested proceeds into new issue municipal bonds and to the Commonwealth of Puerto Rico. |
| **Q** | **Did the Fund's distributions**\*\* **to shareholders change during the 12-month period ended April 30, 2025?** |
| **A** | The Fund's monthly distribution rate began the 12-month period at $0.05 per share in April 2024, and remained at that level through April 30, 2025. The Fund's distributions during the reporting period included returns of capital totaling $0.09 per share. |

|:---|:---|
| **Q** | **Did the level of leverage in the Fund change during the 12-month period April 30, 2025?** |
| **A** | The Fund employs leverage through a credit agreement. (See Note 7 in the Notes to Financial Statements.) On April 30, 2025, 11.1% of the Fund's total managed assets were financed by leverage obtained through the credit agreement, compared with 11.0% of the Fund's total managed assets financed by leverage at the start of the 12-month period on May 1, 2024. The percentage of the Fund's managed assets financed by leverage increased during the 12-month period due to the decrease in the total assets of the Fund. The interest rate on the Fund's leverage decreased by 106 basis points from May 1, 2024 to April 30, 2025. |
| **Q** | **Did the Fund have any exposure to derivatives during the twelve- month period ended April 30, 2025?** |
| **A** | The Fund's limited exposure to U.S. treasury futures had a negligible effect on benchmark relative performance. |
| **Q** | **What is your investment outlook, and how is the Fund positioned heading into its new fiscal year?** |
| **A** | The endpoint for US tariff rates will be an important driver to the domestic economy and financial markets. The outlook for that landing spot remains opaque, particularly given the lack of a clear and achievable objective for tariff policy. Consensus expectations have generally coalesced around the following: (1) the 10% universal tariff will remain but the most extreme reciprocal tariffs will not be implemented, (2) the tariffs on China will be lowered from 145% to around 60%, and (3) sectoral tariffs of 25% will remain on steel, aluminum and autos. While this may be the most likely outcome, it is far from certain, and we view the distribution of potential tariff outcomes as being skewed higher relative to the current consensus. Under this tariff scenario, the US economy could muddle through with slower, but positive, economic growth in the second half of the year. If tariffs end up materially higher than current expectations, however, a US growth recession seems likely in coming quarters. The outlook for Fed policy is similarly bimodal as the dual mandate of stable prices (inflation) and maximum employment (growth) appear to be in tension. We do not expect the Fed to preemptively ease monetary policy to prevent a tariff-driven, or |

| supply shock, recession, particularly when prices are rising sharply, but we do anticipate that the Fed would be willing to ease aggressively to reduce the severity of a recession that is clearly under way. |
| We generally expect credit stability in 2025. We believe potential policy shifts could create both credit negatives and credit positives. For example, some of these policy impacts may be felt in port issuers with broadly applied tariffs impacting bottom lines, hands-off energy policy could benefit traditional energy producing local agencies and states, while Medicaid and Medicare eligibility/reimbursement rate shifts could negatively impact smaller regional health care systems. Important to note is that these policies will take time to filter into the municipal market and will likely not be reflected until later in 2025 and beyond. Further, the stronger than expected economic growth experienced in 2024 generally has left issuers well positioned to weather policy shifts that may occur in 2025. |
| In terms of relative value, thematic trades centered around picking specific sectors will likely remain challenging in an evolving political landscape. Broadly speaking, we expect the AMT transportation sector, which includes airports and toll roads, to outperform. This sector typically is subject to Alternative Minimum Tax (AMT), but if the Tax Cuts and Jobs Act is to be renewed, it could provide a technical tailwind to the sector. There is likely room for spread compression in the sector if the tax code limits the number of individuals subject to the AMT. The prepaid gas sector is another area of interest. This sector stands to benefit from the Trump administration's promise to deregulate the energy industry and to impose tariffs on non-US energy supply. On top of the regulatory tailwind, the sector issues into the longer end of the municipal yield curve, an area we find particularly attractive in today's landscape. |
| On the opposite end of the spectrum is the healthcare/hospital sector, which performed well in 2024, but may be disadvantaged by the historically tight credit spreads with which it entered 2025. Additionally, with the potential for significant Medicare and Medicaid policy shifts, systems with high exposure to these programs could see their budgets compress. We believe the correct sector focus shifts allocations from the hospital sector |

| into the senior living subsector, specifically in systems that are less dependent on Medicaid payments from a credit fundamental standpoint. It will be necessary to remain nimble in the event that policy shifts substantially change the course for certain sectors. |
| Our goal is to invest the Fund in what we believe are fundamentally sound credits representing relative value opportunities, while maintaining an appropriate level of risk management. We also seek to avoid experiencing defaults in the Fund through our emphasis on fundamental research. We believe this steady, long-term approach remains the most effective way to identify opportunities and to help minimize the risk associated with investing in the high-yield municipal market. |

Please refer to the Schedule of Investments on pages 15 - 23 for a full listing of Fund securities.

The Fund is a diversified, closed-end fund. The Fund's primary investment objective is to provide holders with a high level of current income exempt from regular federal income tax. As a secondary investment objective, the Fund may seek capital appreciation to the extent consistent with its primary investment objective. The Fund invests in a professionally managed portfolio of municipal securities from across the United States.

All investments are subject to risk, including the possible loss of principal. In the past several years, financial markets have experienced increased volatility and heightened uncertainty. The market prices of securities may go up or down, sometimes rapidly or unpredictably, due to general market conditions, such as real or perceived adverse economic, political, or regulatory conditions, recessions, inflation, changes in interest or currency rates, lack of liquidity in the bond markets, the spread of infectious illness or other public health issues, armed conflict including Russia's military invasion of Ukraine, sanctions against Russia, other nations or individuals or companies and possible countermeasures, market disruptions caused by tariffs, trade disputes or other government actions, or adverse investor sentiment. These conditions may continue, recur, worsen or spread.

Investments in high-yield or lower-rated securities are subject to greater-than-average risk.

The Fund may invest in securities of issuers that are in default or in bankruptcy.

A portion of income may be subject to state, federal, and/or alternative minimum tax. Capital gains, if any, are subject to a capital gains tax.

When interest rates rise, the prices of debt securities held by the Fund will generally fall. Conversely, when interest rates fall the prices of debt securities held by the Fund generally will rise. A general rise in interest rates could adversely affect the price and liquidity of fixed-income securities.

The value of municipal securities can be adversely affected by changes in financial condition of municipal issuers, lower revenues, and regulatory and political developments. By concentrating in municipal securities, the Fund is more susceptible to adverse economic, political or regulatory developments than is a portfolio that invests more broadly.

Investments in the Fund are subject to possible loss due to the financial failure of the issuers of the underlying securities and the issuers' inability to meet their debt obligations.

[**Table of Contents**](#JOB_Amund_24b87121-7720-4859-9c42-d1ef94d3c34b_TOC)

The Fund may invest in illiquid securities. Illiquid securities may be difficult to dispose of at a price reflective of their value at the times when the Fund believes it is desirable to do so and the market price of illiquid securities is generally more volatile than that of more liquid securities. Illiquid securities also are more difficult to value, and investment of the Fund's assets in illiquid securities may restrict the Fund's ability to take advantage of market opportunities.

The Fund uses leverage, which entails specific risks, to seek a higher return. The Fund may source leverage through a number of methods, including through a credit agreement. Leverage generally magnifies the effect of any increase or decrease in the value of the Fund's underlying assets and creates investment risk with respect to a larger pool of assets than the Fund would otherwise have, potentially resulting in the loss of all assets. Leverage creates significant risks, including the risk that the Fund's incremental income or capital appreciation for investments purchased with the proceeds of leverage will not be sufficient to cover the cost of the leverage, which may adversely affect the return for the holders of common shares.

The Fund is required to maintain certain regulatory and other asset coverage requirements in connection with the use of leverage. In order to maintain required asset coverage levels, the Fund may be required to reduce the amount of leverage employed, alter the composition of the Fund's investment portfolio or take other actions at what might be inopportune times in the market. Such actions could reduce the net earnings or returns to stockholders over time, which is likely to result in a decrease in the market value of the Fund's shares.

Prepayment risk is the chance that an issuer may exercise its right to prepay its security, if falling interest rates prompt the issuer to do so. Forced to reinvest the unanticipated proceeds at lower interest rates, the Fund would experience a decline in income and lose the opportunity for additional price appreciation.

In accordance with the Fund's charter, the Fund intends to terminate on the close of business on August 31, 2033 (the "Termination Date"). In addition, as of a date within twelve months preceding the Termination Date, the Board of the Fund may (but is not required to) cause the Fund to conduct a tender offer to all common stockholders. In connection with the tender offer and/or termination as described in the Fund's prospectus, the Fund will incur transaction costs in connection with dispositions of portfolio securities. The Fund may be required to sell portfolio securities when it otherwise would not, including at times when market conditions are not favorable, which may cause the Fund to lose money. In connection with the tender offer and/or termination as described in the Fund's prospectus, the Fund may begin liquidating all or a portion of its portfolio, and may deviate from its investment policies and may not achieve its investment objective.

Call 1-800-710-0935 or visit www.pioneerinvestments.com or the most recent month-end performance results. Current performance may be lower or higher than the performance data quoted.

Performance data shown represents past performance. Past performance is no guarantee of future results. Investment return and market price will fluctuate, and your shares may trade below NAV due to such factors as interest rate changes and the perceived credit quality of borrowers.

Total investment return does not reflect broker sales charges or commissions. All performance is for common shares of the Fund.

Shares of closed-end funds, unlike open-end funds, are not continuously offered. There is a one-time public offering and, once issued, shares of closed-end funds are bought and sold in the open market through a stock exchange and frequently trade at prices lower than their NAV. NAV per common share is total assets less total liabilities, which include preferred shares or borrowings, as applicable, divided by the number of common shares outstanding.

When NAV is lower than market price, dividends are assumed to be reinvested at the greater of NAV or 95% of the market price.When NAV is higher, dividends are assumed to be reinvested at prices obtained through open-market purchases under the Fund's dividend reinvestment plan.

The performance table and graph do not reflect the deduction of fees and taxes that a stockholders would pay on Fund distributions or the sale of Fund shares. Had these fees and taxes been reflected, performance would have been lower.

The Bloomberg Municipal Bond Index is an unmanaged, broad measure of the municipal bond market.

\* The Fund commenced operations on August 6, 2021.

\*\* The amount of distributions made to stockholders during the period was in excess of the net investment income earned by the Fund during the period. The Fund has accumulated undistributed net investment income which is part of the Fund's net asset value ("NAV"). A portion of this accumulated net investment income was distributed to stockholders during the period. A decrease in distributions may have a negative effect on the market value of the Fund's shares.

(b) Total investment return is calculated assuming a purchase of common shares at the current net asset value or market value on the first day and a sale at the current net asset value or market value on the last day of the periods reported. Dividends and distributions, if any, are assumed for purposes of this calculation to be reinvested at prices obtained under the Fund's dividend reinvestment plan. Total investment return does not reflect brokerage commissions. Past performance is not a guarantee of future results.

(c) For the year ended April 30, 2024, the Fund's total return includes a voluntary reimbursement by the Adviser. If the Fund had not been reimbursed by the Adviser the total return would have been 5.16%.

1. Organization and Signiﬁcant Accounting Policies

Pioneer Municipal High Income Opportunities Fund, Inc. (the "Fund") is a diversified, closed-end management investment company. The Fund is organized as a Maryland corporation. Prior to commencing operations on August 6, 2021, the Fund had no operations other than matters related to its organization and registration under the Investment Company Act of 1940, as amended (the "1940 Act"). The Fund issued 5,000 common shares on June 15, 2021, 15,000,000 common shares on August 5, 2021, 1,000,000 shares on September 14, 2021, and 880,273 shares on September 21, 2021. The Fund's primary investment objective is to provide holders of the Fund's common stock ("Common Shares") with a high level of current income exempt from regular federal income tax. As a secondary investment objective, the Fund may seek capital appreciation to the extent consistent with its primary investment objective. Distributions from sources other than interest income from the Fund's portfolio of municipal securities, including capital gain distributions, are not exempt from regular federal income tax. There can be no assurance that the Fund will achieve its investment objectives.

Until April 1, 2025, Amundi Asset Management US, Inc., an indirect, wholly owned subsidiary of Amundi and Amundi's wholly owned subsidiary, Amundi USA, Inc., served as the Fund's former investment adviser ("Amundi US"). Effective April 1, 2025, Victory Capital Management Inc. ("Victory Capital") serves as the Fund's investment adviser (the "Adviser"). See Note 9.

The Fund is required to comply with Rule 18f-4 under the 1940 Act, which governs the use of derivatives by registered investment companies. Rule 18f-4 permits funds to enter into derivatives transactions (as defined in Rule 18f-4) and certain other transactions notwithstanding the restrictions on the issuance of "senior securities" under Section 18 of the 1940 Act. Rule 18f-4 requires a fund to establish and maintain a comprehensive derivatives risk management program, appoint a derivatives risk manager and comply with a relative or absolute limit on fund leverage risk calculated based on value-at-risk ("VaR"), unless the fund uses derivatives in only a limited manner (a "limited derivatives user"). The Fund is currently a limited derivatives user for purposes of Rule 18f-4.

The Fund adopted Financial Accounting Standards Board Update 2023-07, Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures (ASU 2023-07) during the period. The Fund's adoption of the new standard impacted financial statement disclosures only and did not

[**Table of Contents**](#JOB_Amund_24b87121-7720-4859-9c42-d1ef94d3c34b_TOC)

affect the Fund's financial position or results of operations. The management committee of the Adviser acts as the Fund's Chief Operations Decision Maker (CODM) who assesses performance and allocates resources with respect to the Fund. The Fund's operations constitute a single operating segment and therefore, a single reportable segment, because the Fund has a single investment strategy as disclosed in its prospectus, against which the CODM manages the business activities using information of the Fund as a whole, and assesses performance of the Fund. The financial information provided to and reviewed by the CODM is the same as that presented within the Fund's financial statements.

The Fund is an investment company and follows investment company accounting and reporting guidance under U.S. Generally Accepted Accounting Principles ("U.S. GAAP"). U.S. GAAP requires the management of the Fund to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the ﬁnancial statements, and the reported amounts of income, expenses and gain or loss on investments during the reporting period. Actual results could differ from those estimates.

The following is a summary of signiﬁcant accounting policies followed by the Fund in the preparation of its ﬁnancial statements:

---

| | |
|:---|:---|
| **A.** | **Security Valuation** |
|  | The net asset value of the Fund is computed once daily, on each day the New York Stock Exchange ("NYSE") is open, as of the close of regular trading on the NYSE. |
|  | Fixed-income securities are valued by using prices supplied by independent pricing services, which consider such factors as market prices, market events, quotations from one or more brokers, Treasury spreads, yields, maturities and ratings, or may use a pricing matrix or other fair value methods or techniques to provide an estimated value of the security or instrument. A pricing matrix is a means of valuing a debt security on the basis of current market prices for other debt securities, historical trading patterns in the market for fixed-income securities and/or other factors. Non-U.S. debt securities that are listed on an exchange will be valued at the bid price obtained from an independent third party pricing service. When independent third party pricing services are unable to supply prices, or when prices or market quotations are considered to be unreliable, the value of that security may be determined using quotations from one or more broker-dealers. |
|  | Futures contracts are generally valued at the closing settlement price established by the exchange on which they are traded. |

| | |
|:---|:---|
|  | Securities for which independent pricing services or broker-dealers are unable to supply prices or for which market prices and/or quotations are not readily available or are considered to be unreliable are valued by a fair valuation team comprised of certain personnel of the Adviser. The Adviser is designated as the valuation designee for the Fund pursuant to Rule 2a-5 under the 1940 Act. The Adviser's fair valuation team is responsible for monitoring developments that may impact fair valued securities. |
|  | Inputs used when applying fair value methods to value a security may include credit ratings, the financial condition of the company, current market conditions and comparable securities. The Adviser may use fair value methods if it is determined that a significant event has occurred after the close of the exchange or market on which the security trades and prior to the determination of the Fund's net asset value. Examples of a significant event might include political or economic news, corporate restructurings, natural disasters, terrorist activity or trading halts. Thus, the valuation of the Fund's securities may differ significantly from exchange prices, and such differences could be material. |
| **B.** | **Investment Income and Transactions** |
|  | Interest income, including interest on income-bearing cash accounts, is recorded on the accrual basis. Dividend and interest income are reported net of unrecoverable foreign taxes withheld at the applicable country rates and net of income accrued on defaulted securities. |
|  | Discounts and premiums on purchase prices of debt securities are accreted or amortized, respectively, daily, into interest income on an effective yield to maturity basis with a corresponding increase or decrease in the cost basis of the security. Premiums and discounts related to certain mortgagebacked securities are amortized or accreted in proportion to the monthly paydowns. |
|  | Interest and dividend income payable by delivery of additional shares is reclassified as PIK (payment-in-kind) income upon receipt and is included in interest and dividend income, respectively. |
|  | Security transactions are recorded as of trade date. Gains and losses on sales of investments are calculated on the identified cost method for both financial reporting and federal income tax purposes. |
| **C.** | **Federal Income Taxes** |
|  | It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to |

| distribute all of its net taxable income and net realized capital gains, if any, to its stockholders. Therefore, no provision for federal income taxes is required. As of April 30, 2025, the Fund did not accrue any interest or penalties with respect to uncertain tax positions, which, if applicable, would be recorded as an income tax expense on the Statement of Operations. The tax return filed within the prior year remains subject to examination by federal and state tax authorities. |
| The amount and character of income and capital gain distributions to stockholders are determined in accordance with federal income tax rules, which may differ from U.S. GAAP. Distributions in excess of net investment income or net realized gains are temporary over distributions for financial statement purposes resulting from differences in the recognition or classification of income or distributions for financial statement and tax purposes. Capital accounts within the financial statements are adjusted for permanent book/tax differences to reflect tax character, but are not adjusted for temporary differences. |
| At April 30, 2025, the Fund was permitted to carry forward indefinitely $88,555,184 of short-term losses and $35,969,499 of long-term losses. |
| The tax character of distributions paid during the years ended April 30, 2025 and April 30, 2024, was as follows: |

The difference between book-basis and tax-basis unrealized depreciation is primarily attributable to the tax adjustments related to wash sales and discounts on fixed income securities.

| **D.** | **Automatic Dividend Reinvestment Plan** |
|  | All stockholders whose shares are registered in their own names automatically participate in the Automatic Dividend Reinvestment Plan (the "Plan"), under which participants receive all dividends and capital gain distributions (collectively, dividends) in full and fractional shares of the Fund in lieu of cash. Stockholders may elect not to participate in the Plan. Stockholders not participating in the Plan receive all dividends and capital gain distributions in cash. Participation in the Plan is completely voluntary and may be terminated or resumed at any time without penalty by notifying Equiniti Trust Company, the agent for stockholders in administering the Plan (the "Plan Agent"), in writing prior to any dividend record date; otherwise such termination or resumption will be effective with respect to any subsequently declared dividend or other distribution. |
|  | If a stockholder's shares are held in the name of a brokerage firm, bank or other nominee, the stockholders can ask the firm or nominee to participate in the Plan on the stockholder's behalf. If the firm or nominee does not offer the Plan, dividends will be paid in cash to the stockholders of record. A firm or nominee may reinvest a stockholder's cash dividends in shares of the Fund on terms that differ from the terms of the Plan. |
|  | Whenever the Fund declares a dividend on shares payable in cash, participants in the Plan will receive the equivalent in shares acquired by the Plan Agent either (i) through receipt of additional unissued but authorized shares from the Fund or (ii) by purchase of outstanding shares on the New York Stock Exchange or elsewhere. If, on the payment date for any dividend, the net asset value per share is equal to or less than the market price per share plus estimated brokerage trading fees (market premium), the Plan Agent will invest the dividend amount in newly issued shares. The number of newly issued shares to be credited o each account will be determined by dividing the dollar amount of the dividend by the net asset value per share on the date the shares are issued, provided that the maximum discount from the then current market price per share on the date of issuance does not exceed 5%. If, on the payment date for any dividend, the net asset value per share is greater than the market value (market discount), the Plan Agent will invest the dividend amount in shares acquired in open-market purchases. There are no brokerage charges with respect to newly issued shares. However, each participant will pay a pro rata share of brokerage trading fees incurred with respect to the Plan Agent's open-market purchases. Participating in the Plan does not relieve stockholders from any federal, state or local taxes which may be due on dividends paid in |

any taxable year. Stockholders holding Plan shares in a brokerage account may be able to transfer the shares to another broker and continue to participate in the Plan.

**E.** **Risks** 

---

| |
|:---|
| The value of securities held by the Fund may go up or down, sometimes rapidly or unpredictably, due to general market conditions, such as real or perceived adverse economic, political or regulatory conditions, recessions, the spread of infectious illness or other public health issues, inflation, changes in interest rates, armed conflict such as between Russia and Ukraine or in the Middle East, sanctions against Russia, other nations or individuals or companies and possible countermeasures, lack of liquidity in the bond markets or adverse investor sentiment. In the past several years, financial markets have experienced increased volatility, depressed valuations, decreased liquidity and heightened uncertainty. These conditions may continue, recur, worsen or spread. Inflation and interest rates may increase. These circumstances could adversely affect the value and liquidity of the Fund's investments and negatively impact the Fund's performance. |
| Some sectors of the economy and individual issuers have experienced or may experience particularly large losses. Periods of extreme volatility in the financial markets, reduced liquidity of many instruments, increased government debt, inflation, and disruptions to supply chains, consumer demand and employee availability, may continue for some time. Following Russia's invasion of Ukraine, Russian securities lost all, or nearly all, their market value. Other securities or markets could be similarly affected by past or future political, geopolitical or other events or conditions. |
| Governments and central banks, including the U.S. Federal Reserve, have taken extraordinary and unprecedented actions to support local and global economies and the financial markets. These actions have resulted in significant expansion of public debt, including in the U.S. The consequences of high public debt, including its future impact on the economy and securities markets, may not be known for some time. |
| The U.S. and other countries are periodically involved in disputes over trade and other matters, which may result in tariffs, investment restrictions and adverse impacts on affected companies and securities. For example, the U.S. has imposed tariffs and other trade barriers on Chinese exports, has restricted sales of certain categories of goods to China, and has established barriers to investments in China. Trade disputes may adversely affect the economies of the U.S. and its trading partners, as well as companies directly or indirectly affected and |

| financial markets generally. If the political climate between the U.S. and China does not improve or continues to deteriorate, if China enters into military conflict with Taiwan, the Philippines or another neighbor, or if other geopolitical conflicts develop or get worse, economies, markets and individual securities may be severely affected both regionally and globally, and the value of the Fund's assets may go down. |
| At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making the Fund more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors. |
| Under normal circumstances, the Fund will invest substantially all of its assets in municipal securities. The municipal bond market can be susceptible to unusual volatility, particularly for lower-rated and unrated securities. Liquidity can be reduced unpredictably in response to overall economic conditions or credit tightening. Municipal issuers may be adversely affected by rising health care costs, increasing unfunded pension liabilities, and by the phasing out of federal programs providing financial support. Unfavorable conditions and developments relating to projects financed with municipal securities can result in lower revenues to issuers of municipal securities, potentially resulting in defaults. Issuers often depend on revenues from these projects to make principal and interest payments. The value of municipal securities can also be adversely affected by changes in the financial condition of one or more individual municipal issuers or insurers of municipal issuers, regulatory and political developments, tax law changes or other legislative actions, and by uncertainties and public perceptions concerning these and other factors. Municipal securities may be more susceptible to down-grades or defaults during recessions or similar periods of economic stress. Financial difficulties of municipal issuers may continue or get worse. To the extent the Fund invests significantly in a single state (including New York and California), city, territory (including Puerto Rico), or region, or in securities the payments on which are dependent upon a single project or source of revenues, or that relate to a sector or industry, including tobacco settlement bond revenues, industrial development revenues, health care facilities, education, transportation, special revenues and pollution control, the Fund will be more susceptible to associated risks and developments. |
| The Fund invests primarily in below investment grade (high yield) municipal securities. Debt securities, loans rated below investment grade are commonly referred to as "junk bonds" and are considered speculative with respect to the issuer's capacity to pay interest and repay principal. These securities involve greater risk of loss, are subject |

| to greater price volatility, and may be less liquid and more difficult to value, especially during periods of economic uncertainty or change, than higher rated debt securities. |
| The market prices of the Fund's fixed income securities may fluctuate significantly when interest rates change. The value of your investment will generally go down when interest rates rise. A rise in rates tends to have a greater impact on the prices of longer term or duration securities. For example, if interest rates increase by 1%, the value of a Fund's portfolio with a portfolio duration of ten years would be expected to decrease by 10%, all other things being equal. A general rise in interest rates could adversely affect the price and liquidity of fixed income securities. The maturity of a security may be significantly longer than its effective duration. A security's maturity and other features may be more relevant than its effective duration in determining the security's sensitivity to other factors affecting the issuer or markets generally, such as changes in credit quality or in the yield premium that the market may establish for certain types of securities (sometimes called "credit spread"). In general, the longer its maturity the more a security may be susceptible to these factors. When the credit spread for a fixed income security goes up, or "widens", the value of the security will generally go down. |
| If an issuer or guarantor of a security held by the Fund or a counterparty to a financial contract with the Fund defaults on its obligation to pay principal and/or interest, has its credit rating downgraded or is perceived to be less creditworthy, or the credit quality or value of any underlying assets declines, the value of your investment will typically decline. Changes in actual or perceived creditworthiness may occur quickly. The Fund could be delayed or hindered in its enforcement of rights against an issuer, guarantor or counterparty. |
| With the increased use of technologies such as the Internet to conduct business, the Fund is susceptible to operational, information security and related risks. While the Adviser has established business continuity plans in the event of, and risk management systems to prevent, limit or mitigate, such cyber-attacks, there are inherent limitations in such plans and systems, including the possibility that certain risks have not been identified. Furthermore, the Fund cannot control the cybersecurity plans and systems put in place by service providers to the Fund such as the Fund's custodian and accounting agent, and the Fund's transfer agent. In addition, many beneficial owners of Fund shares hold them through accounts at broker-dealers, retirement platforms and other financial market participants over which neither the Fund nor the Adviser exercises control. Each of these may in turn rely on service providers to |

them, which are also subject to the risk of cyber-attacks. Cybersecurity failures or breaches at the Adviser or the Fund's service providers or intermediaries have the ability to cause disruptions and impact business operations, potentially resulting in financial losses, interference with the Fund's ability to calculate its net asset value, impediments to trading, the inability of Fund stockholders to effect share purchases or sales or receive distributions, loss of or unauthorized access to private stockholder information and violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, or additional compliance costs. Such costs and losses may not be covered under any insurance. In addition, maintaining vigilance against cyber-attacks may involve substantial costs over time, and system enhancements may themselves be subject to cyber-attacks.

2. Investment Advisory Agreement

The Adviser manages the Fund's portfolio. Until April 1, 2025, Amundi US served as the Adviser. Management fees payable under the Fund's Investment Management Agreement with Amundi US were calculated daily and paid monthly at the annual rate of 0.80% of the Fund's average daily managed assets. "Managed assets" means (a) the total assets of the Fund, including any form of investment leverage, minus (b) all accrued liabilities incurred in the normal course of operations, which shall not include any liabilities or obligations attributable to investment leverage obtained through (i) indebtedness of any type (including, without limitation, borrowing through a credit facility or the issuance of debt securities), (ii) the issuance of preferred stock or other similar preference securities, and/or (iii) any other means. For the year ended April 30, 2025, the management fee (excluding waivers and/or assumption of expenses) was 0.80% of the Fund's average daily managed assets, which was equivalent to 0.90% of the Fund's average daily net assets.

Effective April 1, 2025, Victory Capital serves as the Adviser under an interim investment advisory agreement (the "Interim Advisory Agreement") (see note 8). The Interim Advisory Agreement will be in effect until the earlier of (i) stockholder approval of a new investment advisory agreement with Victory Capital or (ii) 150 days after April 1, 2025 (August 29, 2025). The terms of the Interim Advisory Agreement (including fees) are substantially the same as the terms of the Fund's investment advisory agreement with Amundi US. Investment advisory fees payable under the Interim Advisory Agreement will be held in escrow during the term of the Interim Advisory Agreement. At the end of the 150-day period, Victory Capital will be paid the lesser of (a) its costs incurred in performing its services under the Interim Investment Advisory Agreement and (b) the

Effective April 1, 2025 the Adviser has contractually agreed to reimburse expenses so that total annual fund operating expenses (excluding certain items such as interest, taxes, brokerage commissions) do not exceed 2.10%. These expense limitations are in effect through April 1, 2028.

In addition, under the management and administration agreements, certain other services and costs, including accounting, regulatory reporting and insurance premiums, are paid by the Fund as administrative reimbursements Reflected on the Statement of Assets and Liabilities is $154,018 in management fees payable to the Adviser at April 30, 2025.

3. Compensation of Directors and Officers

The Fund paid an annual fee to its Directors. Except for the chief compliance officer, the Fund did not pay any salary or other compensation to its officers. The Fund paid a portion of the chief compliance officer's compensation for his services as the Fund's chief compliance officer. The Adviser paid the remaining portion of the chief compliance officer's compensation. For the year ended April 30, 2025, the Fund paid $8,818 in Officers' and Directors' compensation, which is reflected on the Statement of Operations as Officers'and Directors' fees.

In addition, the Fund reimbursed the transfer agent for out-of-pocket expenses incurred by the transfer agent related to stockholder communications activities such as proxy and statement mailings and outgoing phone calls.

5. Additional Disclosures about Derivative Instruments and Hedging Activities

The Fund's use of derivatives may enhance or mitigate the Fund's exposure to the following risks:

7. Credit Agreement

The Fund has entered into a credit facility (the "Credit Agreement") with The Bank of New York Mellon. There is a $75,000,000 borrowing limit under the Credit Agreement. The outstanding loans under the Credit Agreement bear interest at a rate equal to the Overnight Bank Funding Rate plus 0.95% per annum.

At April 30, 2025, the Fund had a borrowing outstanding under the credit agreement totaling $26,000,000. The interest rate charged at April 30, 2025 was 5.28%. During the year ended April 30, 2025, the average daily balance under the Credit Agreement was $26,000,000 at an average interest rate of 5.77%. Interest expense of $1,499,139 in connection with the Credit Agreement is included on the Statement of Operations.

Borrowings under the Credit Agreement are subject to certain limitations, including (a) that the outstanding amount of the loans under the Credit Agreement cannot exceed the lesser of (i) $75,000,000 and (ii) the sum of the collateral value of all "Eligible Securities" (which consist of nondistressed U.S. municipal bonds, with certain concentration limits) over which The Bank of New York Mellon has a first lien, divided by the "Margin" (which ranges from 120% to 200% depending on the rating of the

Eligible Security) and (b) any limitations imposed by applicable law, including the Investment Company Act of 1940, as amended.

The Credit Agreement renews on a daily basis in perpetuity. The Bank of New York Mellon may, at any time, deliver to the Fund a termination notice, which becomes effective 180 days after its receipt by the Fund.

The Fund was required to maintain 300% asset coverage with respect to amounts outstanding under the Credit Agreement. Asset coverage is calculated by subtracting the Fund's total liabilities not including the credit agreement, from the Fund's total assets and dividing such amount by the principal amount of the borrowing outstanding.

8. Reorganization

Effective April 1, 2025, Amundi US, the Fund's former investment adviser, was combined with Victory Capital Holdings, Inc., the parent company of Victory Capital (the "Transaction").

In connection with the Transaction, Fund stockholders were asked to approve a new investment advisory agreement with Victory Capital (the "New Advisory Agreement") at a special meeting originally scheduled for March 26, 2025 (the "Postponed Meeting"). The Fund postponed its meeting because it had not obtained a sufficient number of votes to approve the New Advisory Agreement.

Because stockholders did not approve the New Advisory Agreement prior to the closing of the Transaction, the Fund entered into an interim investment advisory agreement (the "Interim Advisory Agreement") with Victory Capital, which was approved by the Board and took effect upon the closing of the Transaction. The Interim Advisory Agreement allows Victory Capital to manage each Fund for up to 150 days following the closing of the Transaction (August 29, 2025). Please see Note 2. for additional information regarding the Interim Advisory Agreement.

After considering various options for the Fund, the Board has approved,and recommends that stockholders vote for, the liquidation of the Fund.

The Fund has filed a proxy statement with the U.S. Securities and Exchange Commission ("SEC") with respect to the proposal to liquidate the Fund. Copies of the Fund's proxy statement will be mailed to each stockholder of record of the Fund. Stockholders are advised to read the Fund's proxy statement because it contains important information. The proxy statement and other documents filed by the Fund are available free of charge on the SEC website, www.sec.gov.

[**Table of Contents**](#JOB_Amund_24b87121-7720-4859-9c42-d1ef94d3c34b_TOC)

In light of the Board's approval of a plan of liquidation for the Fund and its recommendation that stockholders of the Fund vote for liquidation pursuant to the plan, the Postponed Meeting will not be rescheduled.

9. Subsequent Events

On May 6, 2025, the Board of the Fund amended the Fund's bylaws to remove Article II, Section 13. That repealed Article II, Section 13 made the Fund subject to the Maryland Control Share Acquisition Act, which had the effect of limiting the voting rights in certain circumstances of a person who acquires more than a certain level of ownership of the Fund's common stock.

A monthly distribution was declared on May 5, 2025 of $0.0500 per common share payable May 30, 2025, to common stockholders of record on May 16, 2025.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and the Stockholders of Pioneer Municipal High Income Opportunities Fund, Inc.:

------

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying statement of assets and liabilities of Pioneer Municipal High Income Opportunities Fund, Inc. (the "Fund"), including the schedule of investments, as of April 30, 2025, and the related statement of operations and statement of cash flows for the year then ended, the statements of changes in net assets and the financial highlights for each of the two years in the period then ended, and the related notes. In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund as of April 30, 2025, and the results of its operations and cash flows for the year then ended, and the changes in net assets and financial highlights for each of the two years in the period then ended in conformity with accounting principles generally accepted in the United States of America. The financial highlights for the year ended April 30, 2023 and the period from August 6, 2021 (commencement of operations) through April 30, 2022 were audited by other auditors. Those auditors expressed an unqualified opinion on those financial highlights in their report dated June 27, 2023.

Basis for Opinion

These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on the Fund's financial statements and financial highlights based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits 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 and financial highlights are free of material misstatement, whether due to error or fraud. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the

effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, 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 and financial highlights. 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 and financial highlights. Our procedures included confirmation of securities owned as of April 30, 2025, by correspondence with the custodian 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.

Investment Objectives, Principal Investment Strategies and Principal Risks (unaudited)

CHANGES OCCURRING DURING MOST RECENT FISCAL YEAR

During the Fund's most recent fiscal year, there were no material changes to the Fund's investment objectives or policies that have not been approved by stockholders or in the principal risk factors associated with investment in the Fund.

INVESTMENT OBJECTIVES

The Fund's primary investment objective is to provide its common stockholders with a high level of current income exempt from regular federal income tax. As a secondary investment objective, the Fund may seek capital appreciation to the extent consistent with its primary investment objective. Distributions from sources other than interest income from the Fund's portfolio of municipal securities, including capital gain distributions, are not exempt from regular federal income tax. There can be no assurance that the Fund will achieve its investment objectives.

The Fund's investment objectives may be changed without stockholder approval. The Fund will provide notice prior to implementing any change to its investment objectives.

PRINCIPAL INVESTMENT STRATEGIES

Normally, the Fund invests at least 80% of its net assets (plus the amount of borrowings, if any, for investment purposes) in securities issued by or on behalf of states, counties, municipalities, territories and possessions of the United States and the District of Columbia and their authorities, political subdivisions, agencies and instrumentalities, the interest on which is exempt from regular federal income tax ("municipal securities"). Derivative instruments that provide exposure to municipal securities or have similar economic characteristics may be used to satisfy the Fund's 80% policy.

The Fund may invest without limit in debt securities of any credit quality, including those rated below investment grade (known as "high yield" or "junk" bonds) or, if unrated, of equivalent credit quality as determined by the Adviser. The Adviser expects that the Fund will invest mainly in securities that are below investment grade. Debt securities rated below investment grade are speculative, tend to be less liquid and are more difficult to value than higher grade securities. The Fund's investments in securities rated below investment grade may include securities that are in default. The Fund may invest in debt securities, loans or preferred stock rated below investment grade or, if unrated, of equivalent credit quality as

48Pioneer Municipal High Income Opportunities Fund, Inc. \| Annual \| 4/30/25

------

[**Table of Contents**](#JOB_Amund_24b87121-7720-4859-9c42-d1ef94d3c34b_TOC)

determined by the Adviser. Such investments may include credit obligations and related instruments of issuers that are insolvent or of issuers that either are in default or are likely to default.

Municipal securities are generally issued to finance public works such as housing, hospitals, schools, mass transportation projects, airports, bridges, highways, and water and sewer works. Municipal securities may be issued to repay outstanding obligations, to raise funds for general operating expenses, or to make loans to other institutions and facilities. They also may be issued by or on behalf of public authorities to finance various privately operated facilities which are expected to benefit the municipality and its residents, such as business, manufacturing, housing, sports and pollution control, as well as public facilities such as airports, mass transit systems, ports and parking. Municipal security issuances may be small, with the securities issued to one or a small number of institutional investors such as the Fund.

The Adviser considers both broad economic factors and issuer specific factors in selecting a portfolio designed to achieve the Fund's investment objectives. In assessing the appropriate maturity and rating weighting of the Fund's portfolio, the Adviser considers a variety of factors that are expected to influence economic activity and interest rates, as well as other economic fundamentals at national, state and regional levels. These factors include fundamental economic indicators, such as the rates of economic growth and inflation, Federal Reserve monetary policy and the relative value of the U.S. dollar compared to other currencies. Once the Adviser determines the preferable portfolio characteristics, the Adviser selects individual securities based upon the terms of the securities (such as yields compared to U.S. Treasuries or comparable issues), liquidity, rating, diversification and perceived risk. The Adviser also employs fundamental research, an evaluation of the obligor based on its financial statements and operations, to assess an obligor's credit quality, taking into account financial condition, future capital needs and potential for change in rating. In making these portfolio decisions, the Adviser relies on the knowledge, experience and judgment of its staff and the staff of its affiliates who have access to a wide variety of research.

In selecting securities to buy and sell, the Adviser considers a security's income and return prospects relative to perceived risk. In making decisions with respect to specific municipal securities, the Adviser employs a disciplined approach, driven primarily by in-depth credit research conducted by the Adviser's investment staff. The Adviser attempts to identify municipal securities available at attractive valuations relative to the Adviser's evaluation of the obligor's creditworthiness and, with respect to private activity bonds, expectations of the revenue supporting the

bonds. The Adviser assesses a security's income, return and risk characteristics as well as a security's impact on the overall income, return and risk characteristics of the Fund. In making this assessment, the Adviser takes into account various factors including the credit quality, maturity, sensitivity to interest rates and the expected after-tax income of the security under consideration and of the Fund's other holdings.

The Adviser anticipates investment opportunities in municipal securities funding projects that involve traditional infrastructure (e.g., bridges, highways, mass transit, and water and sewer), as well as projects that involve social infrastructure. Social infrastructure is broadly defined by the Adviser as the development, construction, improvement or maintenance of facilities that support social services or are intended to improve the quality of life of a community. Types of social infrastructure include education (such as charter schools, other educational facilities and programs, and expansion of internet access), health care (such as hospitals and other medical or dental services), retirement living (such as continuing care retirement facilities and other communities for older adults), and affordable housing, as well as projects with environmental purposes (such as waste disposal and the reduction of pollution or resource use).

The extent to which the Fund invests in specific market segments and project types will depend on the availability of such securities and their income, return and risk characteristics relative to those of other holdings, as well as other portfolio management considerations including diversification and overall credit and interest rate risk.

The Fund's 80% investment policy may not be changed without stockholder approval. The Fund's other investment strategies and policies may be changed from time to time without stockholder approval, unless specifically stated otherwise.

**Portfolio investments. The Fund may invest in a broad range of issuers and segments of the municipal debt securities market. Municipal securities include general obligation bonds, revenue bonds, tax and revenue anticipation notes, bond anticipation notes, tax-exempt commercial paper, municipal leases, participation certificates and custodial receipts. General obligation bonds are backed by the full faith and credit of the issuing entity. Revenue bonds are typically used to fund particular projects, such as those relating to education, health care, transportation and utilities, that are expected to produce income sufficient to make the payments on the bonds, since they are not backed by the full taxing power of the municipality. Housing authority bonds are used primarily to fund low to middle income residential projects and may be backed by the payments made on the underlying mortgages. Tax and revenue anticipation notes are**

generally issued in order to finance short-term cash needs or, occasionally, to finance construction. Tax and revenue anticipation notes are expected to be repaid from taxes or designated revenues in the related period, and they may or may not be general obligations of the issuing entity. Bond anticipation notes are issued with the expectation that their principal and interest will be paid out of proceeds from renewal notes or bonds and may be issued to finance such items as land acquisition, facility acquisition and/or construction and capital improvement projects.

Municipal securities include municipal lease obligations, which are undivided interests issued by a state or municipality in a lease or installment purchase contract which generally relates to equipment or facilities. In some cases, payments under municipal leases do not have to be made unless money is specifically approved for that purpose by an appropriate legislative body.

Although municipal securities are issued by qualifying issuers, payments of principal and interest on municipal securities may be derived solely from revenues from certain facilities, mortgages or private industries, and may not be backed by the issuers themselves. These securities include participation or other interests in municipal securities issued or backed by banks, insurance companies and other financial institutions.

The Fund purchases municipal securities the interest on which, in the opinion of bond counsel at the time the securities are issued, is exempt from regular federal income tax. There is no guarantee that this opinion is correct, and there is no assurance that the IRS will agree with bond counsel's opinion. If the IRS determines that an issuer of a municipal security has not complied with applicable requirements, interest from the security could become subject to regular federal income tax, possibly retroactively to the date the security was issued, and the value of the security could decline significantly and a portion of the distributions to Fund stockholders could be recharacterized as taxable. Future litigation or legislation could adversely affect the tax treatment of municipal securities held by the Fund.

The Fund may invest in municipal securities of any maturity. Municipal securities with longer maturities are generally more volatile than other fixed income securities with shorter maturities. The Fund may invest 25% or more of its assets in issuers in any one or more states or in the same economic sector or similar project type (such as projects relating to health care, education, transportation, and utilities).

The Fund may invest without limit in debt securities of any credit quality, including "high yield" municipal obligations. For this purpose, "high yield" municipal obligations are municipal obligations rated at the time of

purchase Ba or lower by Moody's or BB or lower by S&P or unrated securities determined by the Adviser to be of comparable credit quality. The Adviser expects that the Fund will invest mainly in securities that are below investment grade. Municipal securities of below investment grade quality are regarded as having predominantly speculative characteristics with respect to the issuer's capacity to pay interest and repay principal, and are commonly referred to as "junk bonds." The Fund may invest in securities in any rating category, including those in default, and in debtor-in-possession financings. The Fund may invest in debt securities, loans or preferred stock rated below investment grade or, if unrated, of equivalent credit quality as determined by the Adviser. Such investments may include credit obligations and related instruments of issuers that are insolvent or of issuers that either are in default or are likely to default.

Interest income from certain types of municipal securities in which the Fund may invest generally may be subject to the federal alternative minimum tax (the "AMT"). The Fund may not be suitable for investors subject to the AMT. The rate of interest paid on municipal securities normally is lower than the rate of interest paid on taxable securities.

The Fund's investments may have fixed or variable principal payments and all types of interest rate payment and reset terms, including fixed and floating rates, inverse floating rate, zero coupon, contingent, deferred and payment in kind and auction rate features.

The Fund also may invest in subordinated securities, asset-backed securities of any rating, and may hold cash or other short-term investments. A holder of securities that are subordinated or "junior" to more senior securities of an issuer is entitled to payment after the holders of more senior securities of the issuer. The Fund's investments may include mortgage-backed instruments, the underlying assets of which allow for balloon payments (where a substantial portion of a mortgage loan balance is paid at maturity, which can shorten the average life of the mortgage-backed instrument) or negative amortization payments (where, as a result of a payment cap, payments on a mortgage loan are less than the amount of principal and interest owed, with excess amounts added to the outstanding principal balance, which can extend the average life of the mortgage-backed instrument).

The Fund may invest up to 20% of its net assets in taxable investments, including securities of other investment companies (including mutual funds, exchange-traded funds and closed-end funds), commercial paper, U.S. government securities, U.S. or foreign bank instruments and repurchase agreements.

The Fund may invest in securities and instruments that are not income-producing for purposes of seeking capital appreciation or managing risk or other portfolio characteristics.

**Municipal securities. Municipal securities are often issued to obtain funds for various public purposes, including refunding outstanding obligations, funding for general operating expenses and lending to other public institutions and facilities. Municipal securities also include certain "private activity bonds" or industrial development bonds, which are issued by or on behalf of public authorities to provide financing aid to acquire sites or construct or equip facilities within a municipality for privately or publicly owned corporations. The two principal classifications of municipal securities are "general obligations" and "revenue obligations." General obligations are secured by the issuer's pledge of its full faith and credit for the payment of principal and interest, although the characteristics and enforcement of general obligations may vary according to the law applicable to the particular issuer. Revenue obligations, which include, but are not limited to, private activity bonds, certificates of participation and certain municipal notes, are not backed by the credit and taxing authority of the issuer and are payable solely from the revenues derived from a particular facility or class of facilities or, in some cases, from the proceeds of a special excise or other specific revenue source. The obligations of the issuer of a revenue obligation may, in addition, be backed by a letter of credit from a bank, a guarantee from another issuer or insurance. The credit rating assigned to municipal securities may reflect the existence of these guarantees, letters of credit or other credit enhancement features. General obligations and revenue obligations may be issued in a variety of forms, including commercial paper, fixed, variable and floating rate securities, tender option bonds, auction rate bonds, zero coupon bonds, deferred interest bonds and capital appreciation bonds. In addition to general obligations and revenue obligations, there are a variety of hybrid and special types of municipal securities.**

One or a small number of institutional investors such as the Fund may purchase an entire issue of municipal securities. Thus, the issue may not be said to be publicly offered. Unlike some securities that are not publicly offered, a secondary market exists for many municipal securities that were not publicly offered initially and such securities may be readily marketable.

Although distributions of interest income from the Fund's municipal securities are generally exempt from regular federal income tax, distributions from other sources, including capital gain distributions, and any gains on the sale of your common shares are not. You should consult

your tax adviser as to whether the AMT applies to you and as to whether you will be subject to state and local taxes on your distributions from the Fund.

From time to time, proposals have been introduced before Congress for the purpose of restricting or eliminating the federal income tax exemption for interest on municipal securities. The Fund cannot predict what legislation, if any, may be proposed in the future in Congress regarding the federal income tax status of interest on municipal securities. Such proposals, if enacted, might materially and adversely affect the Fund.

The Fund may invest in municipal securities that are collateralized by the proceeds from class action or other litigation against the tobacco industry. Payment by tobacco industry participants of such proceeds is spread over several years, and the collection and distribution of such proceeds to the issuers of municipal securities is dependent upon the financial health of such tobacco industry participants, which cannot be assured. Additional litigation, government regulation or prohibition on the sales of tobacco products, or the seeking of protection under the bankruptcy laws, could adversely affect the tobacco industry, which, in turn, could have an adverse affect on tobacco-related municipal securities.

**Municipal leases and certificates of participation. The Fund may invest in municipal leases and certificates of participation in such leases. A municipal lease is an obligation in the form of a lease or installment purchase that is issued by a state or local government to acquire equipment and facilities. Income from such obligations is generally exempt from state and local taxes in the state of issuance. Municipal leases frequently involve special risks not normally associated with general obligations or revenue obligations. Leases and installment purchase or conditional sale contracts (which normally provide for title to the leased asset to pass eventually to the governmental issuer) have evolved as a means for governmental issuers to acquire property and equipment without meeting the constitutional and statutory requirements for the issuance of debt. The debt issuance limitations are deemed to be inapplicable because of the inclusion in many leases or contracts of "non-appropriation" clauses that relieve the governmental issuer of any obligation to make future payments under the lease or contract unless money is appropriated for such purpose by the appropriate legislative body on a yearly or other periodic basis. In addition, such leases or contracts may be subject to the temporary abatement of payments in the event the issuer is prevented from maintaining occupancy of the leased premises or utilizing the leased equipment. Although the obligations may be secured by the leased equipment or facilities, the disposition of the property in the event of non-appropriation or foreclosure might prove difficult, time consuming and costly, and result in a delay in**

recovering, or the failure to fully recover, the Fund's original investment. To the extent that the Fund invests in unrated municipal leases or participates in such leases, the credit quality and risk of cancellation of such unrated leases will be monitored on an ongoing basis.

A certificate of participation represents an undivided interest in an unmanaged pool of municipal leases, installment purchase agreements or other instruments. The certificates are typically issued by a municipal agency, a trust or other entity that has received an assignment of the payments to be made by the state or political subdivision under such leases or installment purchase agreements. Such certificates provide the Fund with the right to a pro rata undivided interest in the underlying municipal securities. In addition, such participations generally provide the Fund with the right to demand payment, on not more than seven days' notice, of all or any part of the Fund's participation interest in the underlying municipal securities, plus accrued interest.

Certain municipal lease obligations and certificates of participation may be deemed to be illiquid. Other municipal lease obligations and certificates of participation acquired by the Fund may be determined by the Adviser, pursuant to guidelines adopted by the Board, to be liquid securities. In determining the liquidity of municipal lease obligations and certificates of participation, the Adviser will consider a variety of factors, including: (i) the willingness of dealers to bid for the obligation; (ii) the number of dealers willing to purchase or sell the obligation and the number of other potential buyers; (iii) the frequency of trades or quotes for the obligation; and (iv) the nature of the marketplace trades. In addition, the Adviser will consider factors unique to particular lease obligations and certificates of participation affecting the marketability thereof. These include the general creditworthiness of the issuer, the importance to the issuer of the property covered by the lease and the likelihood that the marketability of the obligation will be maintained throughout the time the obligation is held by the Fund.

**Municipal notes. Municipal securities in the form of notes generally are used to provide for short-term capital needs, in anticipation of an issuer's receipt of other revenues or financing, and typically have maturities of up to three years. Such instruments may include tax anticipation notes, revenue anticipation notes, bond anticipation notes, tax and revenue anticipation notes and construction loan notes. Tax anticipation notes are issued to finance the working capital needs of governments. Generally, they are issued in anticipation of various tax revenues, such as income, sales, property, use and business taxes, and are payable from these specific future taxes. Revenue anticipation notes are issued in expectation of receipt of other kinds of revenue, such as federal revenues available under**

federal revenue sharing programs. Bond anticipation notes are issued to provide interim financing until long-term bond financing can be arranged. In most cases, the long-term bonds then provide the funds needed for repayment of the notes. Tax and revenue anticipation notes combine the funding sources of both tax anticipation notes and revenue anticipation notes. Construction loan notes are sold to provide construction financing. Mortgage notes insured by the Federal Housing Authority secure these notes; however, the proceeds from the insurance may be less than the economic equivalent of the payment of principal and interest on the mortgage note if there has been a default. The anticipated revenues from taxes, grants or bond financing generally secure the obligations of an issuer of municipal notes. An investment in such instruments, however, presents a risk that the anticipated revenues will not be received or that such revenues will be insufficient to satisfy the issuer's payment obligations under the notes or that refinancing will be otherwise unavailable.

**Tax-exempt commercial paper. Issues of commercial paper typically represent short-term, unsecured, negotiable promissory notes. These obligations are issued by state and local governments and their agencies to finance the working capital needs of municipalities or to provide interim construction financing and are paid from general revenues of municipalities or are refinanced with long-term debt. In most cases, tax-exempt commercial paper is backed by letters of credit, lending agreements, note repurchase agreements or other credit facility agreements offered by banks or other institutions.**

**Pre-refunded municipal securities. The principal of and interest on pre-refunded municipal securities are no longer paid from the original revenue source for the securities. Instead, the source of such payments is typically an escrow fund consisting of U.S. government securities. The assets in the escrow fund are derived from the proceeds of refunding bonds issued by the same issuer as the pre-refunded municipal securities. Issuers of municipal securities use this advance refunding technique to obtain more favorable terms with respect to securities that are not yet subject to call or redemption by the issuer. For example, advance refunding enables an issuer to refinance debt at lower market interest rates, restructure debt to improve cash flow or eliminate restrictive covenants in the indenture or other governing instrument for the pre-refunded municipal securities. However, except for a change in the revenue source from which principal and interest payments are made, the pre-refunded municipal securities remain outstanding on their original terms until they mature or are redeemed by the issuer.**

#### Private activity bonds. Private activity bonds, formerly referred to as industrial development bonds, are issued by or on behalf of public
56Pioneer Municipal High Income Opportunities Fund, Inc. \| Annual \| 4/30/25

[**Table of Contents**](#JOB_Amund_24b87121-7720-4859-9c42-d1ef94d3c34b_TOC)

authorities to obtain funds to provide privately operated housing facilities, airport, mass transit or port facilities, sewage disposal, solid waste disposal or hazardous waste treatment or disposal facilities and certain local facilities for water supply, gas or electricity. Other types of private activity bonds, the proceeds of which are used for the construction, equipment, repair or improvement of privately operated industrial or commercial facilities, may constitute municipal securities, although the current federal tax laws place substantial limitations on the size of such issues. The Fund's distributions of its interest income from private activity bonds may subject certain investors to the AMT.

**Tender option bonds. A tender option bond is a municipal security (generally held pursuant to a custodial arrangement) having a relatively long maturity and bearing interest at a fixed rate substantially higher than prevailing short-term, tax-exempt rates. The bond is typically issued with the agreement of a third party, such as a bank, broker-dealer or other financial institution, which grants the security holders the option, at periodic intervals, to tender their securities to the institution and receive the face value thereof. As consideration for providing the option, the financial institution receives periodic fees equal to the difference between the bond's fixed coupon rate and the rate, as determined by a remarketing or similar agent at or near the commencement of such period, that would cause the securities, coupled with the tender option, to trade at par on the date of such determination. Thus, after payment of this fee, the security holder effectively holds a demand obligation that bears interest at the prevailing short-term, tax-exempt rate. However, an institution will not be obligated to accept tendered bonds in the event of certain defaults or a significant downgrade in the credit rating assigned to the issuer of the bond. The liquidity of a tender option bond is a function of the credit quality of both the bond issuer and the financial institution providing liquidity. Tender option bonds are deemed to be liquid unless, in the opinion of the Adviser, the credit quality of the bond issuer and the financial institution is deemed, in light of the Fund's credit quality requirements, to be inadequate and the bond would not otherwise be readily marketable. The Fund intends to invest in tender option bonds the interest on which will, in the opinion of bond counsel, counsel for the issuer of interests therein or counsel selected by the Adviser, be exempt from regular federal income tax. However, because there can be no assurance that the IRS will agree with such counsel's opinion in any particular case, there is a risk that the Fund will not be considered the owner of such tender option bonds and thus will not be entitled to treat such interest as exempt from such tax. Additionally, the federal income tax treatment of certain other aspects of these investments, including the proper tax treatment of tender option bonds and the associated fees in relation to various regulated investment**

company tax provisions, is unclear. The Fund intends to manage its portfolio in a manner designed to eliminate or minimize any adverse impact from the tax rules applicable to these investments.

**Auction rate securities. The Fund may invest in auction rate securities. Auction rate securities include auction rate municipal securities and auction rate preferred securities issued by closed-end investment companies that invest primarily in municipal securities (collectively, "auction rate securities"). Provided that the auction mechanism is successful, auction rate securities usually permit the holder to sell the securities in an auction at par value at specified intervals. The dividend is reset by a "Dutch" auction in which bids are made by broker-dealers and other institutions for a certain amount of securities at a specified minimum yield. The dividend rate set by the auction is the lowest interest or dividend rate that covers all securities offered for sale. While this process is designed to permit auction rate securities to be traded at a value equal to the liquidation preference, there is some risk that an auction will fail due to insufficient demand for the securities. The Fund will take the time remaining until the next scheduled auction date into account for the purpose of determining the securities' duration. The Fund's investments in auction rate securities of closed-end funds are subject to the limitations prescribed by the 1940 Act.**

**Illiquid securities. The Fund may invest in bonds or other municipal securities that lack a secondary trading market or are otherwise considered illiquid. Liquidity of a security relates to the ability easily to dispose of the security and the price to be obtained upon disposition of the security, which may be less than would be obtained for a comparable, more liquid security. The Fund may invest without limit in illiquid investments due to the closed-end fund structure. Such investments may affect the Fund's ability to realize its net asset value in the event of a voluntary or involuntary liquidation of its assets.**

**Structured securities. The Fund may invest in structured securities. The value of the principal and/or interest on such securities is determined by reference to changes in the value of specific currencies, interest rates, commodities, indices or other financial indicators ("reference") or the relative change in two or more references. The interest rate or the principal amount payable upon maturity or redemption may be increased or decreased depending upon changes in the reference. The terms of the structured securities may provide, in certain circumstances, that no principal is due at maturity and, therefore, may result in a loss of the Fund's investment. Changes in the interest rate or principal payable at maturity may be a multiple of the changes in the value of the reference. Consequently, structured securities may entail a greater degree of market risk than other types of fixed income securities.**

[**Table of Contents**](#JOB_Amund_24b87121-7720-4859-9c42-d1ef94d3c34b_TOC)

**Insured municipal securities. The Fund may invest in "insured" municipal securities, which are securities for which scheduled payments of interest and principal are guaranteed by a private (non-governmental) insurance company. The insurance only entitles the Fund to receive at maturity the face or par value of the securities held by the Fund. The insurance does not guarantee the market value of the municipal securities or the value of the shares of the Fund. The Fund may utilize new issue or secondary market insurance. A bond issuer who wishes to increase the credit rating of a security purchases a new issue insurance policy. By paying a premium and meeting the insurer's underwriting standards, the bond issuer is able to obtain a high credit rating (usually, Aaa from Moody's or AAA from S&P) for the issued security. Such insurance is likely to increase the purchase price and resale value of the security. New issue insurance policies are non-cancelable and continue in force as long as the bonds are outstanding. A secondary market insurance policy is purchased by an investor subsequent to a bond's original issuance and generally insures a particular bond for the remainder of its term.**

**Standby commitments. In order to enhance the liquidity of municipal securities, the Fund may acquire the right to sell a security to another party at a guaranteed price and date. Such a right to resell may be referred to as a "standby commitment" or "liquidity put," depending on its characteristics. The aggregate price which the Fund pays for securities with standby commitments may be higher than the price which otherwise would be paid for the securities. Standby commitments may not be available or may not be available on satisfactory terms. Standby commitments may involve letters of credit issued by domestic or foreign banks supporting the other party's ability to purchase the security. The right to sell may be exercisable on demand or at specified intervals and may form part of a security or be acquired separately by the Fund.**

Because the period prior to the put date is generally less than 365 days, the Fund generally values the municipal securities subject to standby commitments at amortized cost. The Board has adopted procedures pursuant to which the Adviser may determine that amortized cost represents the fair value of these securities. The exercise price of the standby commitments is expected to approximate such amortized cost. Consequently, no separate value is assigned to standby commitments for purposes of determining the Fund's net asset value. The cost of a standby commitment is carried as unrealized depreciation from the time of purchase until it is exercised or expires. Since the value of a standby commitment is dependent on the ability of the standby commitment writer to meet its obligation to repurchase, the Fund's policy is to enter into standby commitment transactions only with banks, brokers or dealers that present a

minimal risk of default. However, this policy reduces, but does not eliminate, the risk of default by the standby commitment writer.

**U.S. government securities. The Fund may invest in U.S. government securities. U.S. government securities are obligations of, or guaranteed by, the U.S. government, its agencies or government-sponsored entities. U.S. government securities include obligations: directly issued by or supported by the full faith and credit of the U.S. government, like Treasury bills, notes and bonds and Government National Mortgage Association (GNMA) certificates; supported by the right of the issuer to borrow from the U.S. Treasury, like those of the Federal Home Loan Banks (FHLBs); supported by the discretionary authority of the U.S. government to purchase the agency's securities like those of the Federal National Mortgage Association (FNMA); or supported only by the credit of the issuer itself, like the Tennessee Valley Authority. U.S. government securities include issues by non-governmental entities (like financial institutions) that carry direct guarantees from U.S. government agencies as part of government initiatives in response to the market crisis or otherwise. U.S. government securities include zero coupon securities that make payments of interest and principal only upon maturity and which therefore tend to be subject to greater volatility than interest-bearing securities with comparable maturities. Although the U.S. government guarantees principal and interest payments on securities issued by the U.S. government and some of its agencies, such as securities issued by the GNMA, this guarantee does not apply to losses resulting from declines in the market value of these securities. Some of the U.S. government securities that the Fund may hold are not guaranteed or backed by the full faith and credit of the U.S. government, such as those issued by FNMA and the Federal Home Loan Mortgage Corporation (FHLMC).**

**Debtor-in-possession financings. The Fund may participate in or acquire debtor-in-possession financings (commonly known as "DIP financings"). DIP financings are arranged when an entity seeks the protections of the bankruptcy court under Chapter 11 of the U.S. bankruptcy code. These financings allow the entity to continue its business operations while reorganizing under Chapter 11. Such financings constitute senior liens on unencumbered security (i.e., security not subject to other creditors' claims). There is a risk that the entity will not emerge from Chapter 11 and be forced to liquidate its assets under Chapter 7 of the U.S. Bankruptcy Code. In the event of liquidation, the Fund's only recourse would be against the property securing the DIP financing.**

**Investments in mortgage-backed, asset-backed and other securities. The Fund may invest in mortgage-backed securities. Mortgage-backed securities may be issued by private issuers, by government-sponsored entities such as**

FNMA or FHLMC or by agencies of the U.S. government, such as GNMA. Mortgage-backed securities represent direct or indirect participation in, or are collateralized by and payable from, mortgage loans secured by real property. The commercial mortgages underlying certain commercial mortgage-backed securities generally allow all or a substantial portion of the loan balance to be paid at maturity, commonly known as a balloon payment. Some mortgage loans restrict periodic adjustments by limiting changes in the borrower's monthly principal and interest payments rather than limiting interest rate changes. These payment caps may result in negative amortization, where payments are less than the amount of principal and interest owed, with excess amounts added to the outstanding principal balance, which can extend the average life of the mortgage-backed securities.

The Fund may invest in asset-backed securities and in securities issued by entities, such as trusts, whose underlying assets are municipal securities. The Fund may invest in collateralized debt obligations (CDOs), which include collateralized bond obligations (CBOs), collateralized loan obligations (CLOs) and other similarly structured securities. A CDO is a trust backed by a pool of fixed income securities. The trust typically is split into two or more portions, called tranches, which vary in credit quality and yield. Lower tranches pay higher interest rates but represent lower degrees of credit quality and are more sensitive to the rate of defaults in the pool of obligations. Certain CDOs may use derivatives, such as credit default swaps, to create synthetic exposure to assets rather than holding such assets directly.

**Subordinated securities. The Fund may invest in securities that are subordinated or "junior" to more senior securities of the issuer. The investor in a subordinated security of an issuer is entitled to payment after other holders of debt in that issuer.**

**Zero coupon securities. The Fund may invest in zero coupon securities. Zero coupon securities are debt instruments that do not pay interest during the life of the security but are issued at a discount from the amount the investor will receive when the issuer repays the amount borrowed (the face value). The discount approximates the total amount of interest that would be paid at an assumed interest rate.**

**Derivatives. The Fund may, but is not required to, invest without limit in synthetic municipal securities and other structured securities, inverse floating rate obligations, credit default swaps and other derivatives. Credit default swaps can be used to acquire or to transfer the credit risk of a security or index of securities without buying or selling the security or securities comprising the relevant index. A derivative is a security or**

instrument whose value is determined by reference to the value or the change in value of one or more securities, currencies, indices or other financial instruments. The Fund may use derivatives for a variety of purposes, including:

• In an attempt to hedge against adverse changes in the market prices of securities, interest rates or currency exchange rates

• As a substitute for purchasing or selling securities

• To attempt to increase the Fund's return as a non-hedging strategy that may be considered speculative

• To manage portfolio characteristics (for example, the duration or credit quality of the Fund's portfolio)

• As a cash flow management technique

The Fund may choose not to make use of derivatives for a variety of reasons, and any use may be limited by applicable law and regulations. Derivative instruments are valued based on their mark-to market value in accordance with the Adviser's valuation procedures adopted pursuant to Rule 2a-5 under the 1940 Act.

**Other investment companies. The Fund may invest in the securities of other investment companies to the extent that such investments are consistent with the Fund's investment objectives and principal investment strategies and permissible under the 1940 Act. Subject to the limitations on investment in other investment companies, the Fund may invest in**

exchange-traded funds ("ETFs"). The Fund does not currently intend to invest in investment companies that are not registered under the 1940 Act.

**Repurchase agreements. In a repurchase agreement, the Fund purchases securities from a broker/dealer or a bank, called the counterparty, upon the agreement of the counterparty to repurchase the securities from the Fund at a later date, and at a specified price, which is typically higher than the purchase price paid by the Fund. The securities purchased serve as the Fund's collateral for the obligation of the counterparty to repurchase the securities. If the counterparty does not repurchase the securities, the Fund is entitled to sell the securities, but the Fund may not be able to sell them for the price at which they were purchased, thus causing a loss. Additionally, if the counterparty becomes insolvent, there is some risk that the Fund will not have a right to the securities, or the immediate right to sell the securities.**

**Reverse repurchase agreements. The Fund may enter into reverse repurchase agreements, which involve the sale of securities held by the Fund subject to its agreement to repurchase the securities at an agreed-upon date or upon demand and at a price reflecting a market rate of interest. Reverse repurchase agreements are subject to the Fund's limitation on borrowings and may be entered into only with banks or securities dealers or their affiliates. While a reverse repurchase agreement is outstanding, the Fund will maintain the segregation, either on its records or with the Fund's custodian, of cash or other liquid securities, marked to market daily, in an amount at least equal to its obligations under the reverse repurchase agreement.**

Reverse repurchase agreements involve the risk that the buyer of the securities sold by the Fund might be unable to deliver them when the Fund seeks to repurchase. If the buyer of securities under a reverse repurchase agreement files for bankruptcy or becomes insolvent, the buyer or trustee or receiver may receive an extension of time to determine whether to enforce the Fund's obligation to repurchase the securities, and the Fund's use of the proceeds of the reverse repurchase agreement may effectively be restricted pending such decision.

**Use of leverage by the Fund. The Fund anticipates using leverage in order to pursue its investment objectives. The Fund may use leverage to the extent permitted by the 1940 Act. The Fund may source leverage initially and throughout the life of the Fund through a number of methods including through borrowings, issuing preferred shares, which have seniority over the common shares, the issuance of debt securities, entering into reverse repurchase agreements (effectively a borrowing), and investing in residual interest certificates of tender option bond trusts, also called inverse**

floating rate securities, that have the economic effect of leverage because the Fund's investment exposure to the underlying bonds held by the trust have been effectively financed by the trust's issuance of floating rate certificates. The sources of leverage will vary depending on market conditions. The Fund anticipates using such leverage in an aggregate amount equal to approximately 30% of the Fund's managed assets, if current market conditions persist. The Fund initially intends to leverage its assets through borrowings from banks and other financial institutions. It is expected that these borrowings will be made pursuant to a revolving credit facility established with a bank or other financial institution. Under the 1940 Act, the Fund is generally not permitted to incur indebtedness unless immediately after such borrowing the Fund has asset coverage of at least 300% of the aggregate outstanding principal balance of indebtedness. The fees and expenses attributed to leverage, including all offering expenses, will be borne by holders of common shares.

The Fund may not be leveraged at all times, and the amount of leverage, if any, may vary depending on a variety of factors, including the Adviser's outlook for interest rates and credit markets and the costs that the Fund would incur as a result of such leverage. The Fund's leveraging strategy may not be successful. By leveraging its investment portfolio, the Fund creates an opportunity for increased net income or capital appreciation. However, the use of leverage also creates risks for the Fund's stockholders, including the likelihood of greater volatility of the Fund's net asset value and market price. There is a risk that fluctuations in the interest rates on any leverage may adversely affect the return to the Fund's stockholders. If the return on the securities purchased with such funds is not sufficient to cover the cost of leverage, the return on the Fund will be less than if leverage had not been used, and therefore the amount available for distribution to the Fund's stockholders as dividends and other distributions will be reduced. Because the fees paid to the Adviser will be calculated on the basis of the Fund's managed assets (which include the proceeds of leverage), the fees will be higher when leverage is utilized, giving the Adviser an incentive to utilize leverage. The Fund generally will not utilize leverage if it anticipates that it would result in a lower return to the Fund's common stockholders over time.

If the Fund uses leverage, associated costs will be borne by common stockholders through a reduction of the NAV of the Fund's common shares. Costs associated with leverage would likely include legal fees, audit fees, rating agency fees, structuring fees, commitment fees, and a usage (borrowing) fee. If the Fund issues preferred shares or debt, holders of preferred shares and holders of any debt issued by the Fund would not bear

the advisory fee. Therefore, common stockholders bear the portion of the advisory fee attributable to the assets purchased with the proceeds of leverage.

**Limited term and eligible tender offer. In accordance with the Fund's charter, the Fund intends to terminate on the close of business on August 31, 2033 (the "Termination Date"); provided, that if the Board of Directors (the "Board") believes that it is in the best interests of the Fund to do so, the Fund may extend the Termination Date: (i) once for up to one year (i.e., up to August 31, 2034), and (ii) once for up to an additional six months (i.e., up to February 28, 2035 (which date shall then become the Termination Date)), in each case upon the affirmative vote of a majority of the entire Board and without stockholder approval. In determining whether to extend the Termination Date, the Board may consider the inability to sell the Fund's assets in a time frame consistent with termination due to lack of market liquidity or other extenuating circumstances. Additionally, the Board may determine that market conditions are such that it is reasonable to believe that, with an extension, the Fund's remaining assets will appreciate and generate income in an amount that, in the aggregate, is meaningful relative to the cost and expense of continuing the operation of the Fund.**

Beginning one year before the Termination Date (the "wind-down period"), the Fund may begin liquidating all or a portion of the Fund's portfolio, and may deviate from its investment policies and may not achieve its investment objectives. In addition, within twelve months preceding the Termination Date, the Board may (but is not required to) cause the Fund to conduct an Eligible Tender Offer. An Eligible Tender Offer would consist of a tender offer to all common stockholders to purchase common shares of the Fund at a price equal to the net asset value ("NAV") per common share on the expiration date of the tender offer. The Board has established that, following an Eligible Tender Offer, the Fund must have at least $100 million of net assets to ensure the continued viability of the Fund (the "Termination Threshold").

In an Eligible Tender Offer, the Fund will offer to purchase all common shares held by each common stockholder; provided, that if the number of properly tendered common shares would result in the Fund's net assets totaling less than the Termination Threshold, the Eligible Tender Offer will be terminated and no common shares will be repurchased pursuant to the Eligible Tender Offer. Instead, the Fund will begin (or continue) liquidating its portfolio and proceed to terminate on or before the Termination Date. The Adviser will pay all costs and expenses associated with the making of an Eligible Tender Offer, other than brokerage and related transaction costs associated with disposition of portfolio investments in connection with the

Pioneer Municipal High Income Opportunities Fund, Inc. \| Annual \| 4/30/2565

[**Table of Contents**](#JOB_Amund_24b87121-7720-4859-9c42-d1ef94d3c34b_TOC)

Eligible Tender Offer, which will be borne by the Fund and its stockholders. An Eligible Tender Offer would be made, and common stockholders would be notified thereof, in accordance with the requirements of the Investment Company Act of 1940 (the "1940 Act"), the Securities Exchange Act of 1934 (the "Exchange Act") and the applicable tender offer rules thereunder (including Rule 13e-4 and Regulation 14E under the Exchange Act).

If the number of properly tendered common shares would result in the Fund's net assets totaling greater than the Termination Threshold, all common shares properly tendered and not withdrawn will be purchased by the Fund pursuant to the terms of the Eligible Tender Offer. Following the completion of the Eligible Tender Offer, the Board may eliminate the Termination Date upon the affirmative vote of a majority of the Board and without stockholder approval and provide for the Fund's perpetual existence. In making a decision to eliminate the Termination Date to provide for the Fund's perpetual existence, the Board will take such actions with respect to the continued operations of the Fund as it deems to be in the best interests of the Fund, based on market conditions at such time, the extent of common stockholder participation in the Eligible Tender Offer and all other factors deemed relevant by the Board in consultation with the Adviser, taking into account that the Adviser may have a potential conflict of interest in seeking to convert to a perpetual fund.

The Fund is not a so called "target date" or "life cycle" fund whose asset allocation becomes more conservative over time as its target date, often associated with retirement, approaches. In addition, the Fund is not a "target term" fund whose investment objective is to return its original NAV on the Termination Date. The Fund's investment objectives and policies are not designed to seek to return to investors that purchase common shares in this offering their initial investment of $20.00 per common share on the Termination Date or in an Eligible Tender Offer, and such investors and investors that purchase common shares after the completion of this offering may receive more or less than their original investment upon termination or in an Eligible Tender Offer.

Upon its termination, the Fund will distribute substantially all of its net assets to common stockholders, after paying or otherwise providing for all charges, taxes, expenses and liabilities, whether due or accrued or anticipated, of the Fund, as may be determined by the Board.

PRINCIPAL RISKS

**General. The Fund is a diversified, closed-end management investment company designed primarily as a long-term investment and not as a trading tool. The Fund is not a complete investment program and should be considered only as an addition to an investor's existing portfolio of**

66Pioneer Municipal High Income Opportunities Fund, Inc. \| Annual \| 4/30/25

------

[**Table of Contents**](#JOB_Amund_24b87121-7720-4859-9c42-d1ef94d3c34b_TOC)

investments. Due to uncertainty inherent in all investments, there can be no assurance that the Fund will achieve its investment objectives.

**Market price of shares. Common shares of closed-end funds frequently trade at a price lower than their NAV. This is commonly referred to as "trading at a discount." This characteristic of shares of closed-end funds is a risk separate and distinct from the risk that the Fund's NAV may decrease. Both long and short-term investors, including investors who sell their shares within a relatively short period after completion of the initial public offering, will be exposed to this risk. The Fund is designed primarily for long-term investors and should not be considered a vehicle for trading purposes.**

Whether investors will realize a gain or loss upon the sale of the Fund's Common Shares will depend upon whether the market value of the shares at the time of sale is above or below the price the investor paid, taking into account transaction costs, for the shares and is not directly dependent upon the Fund's NAV. Because the market value of the Fund's shares will be determined by factors such as the relative demand for and supply of the shares in the market, general market conditions and other factors beyond the control of the Fund, the Fund cannot predict whether its common shares will trade at, below or above NAV, or below or above the initial offering price for the shares.

**Limited term risk. Unless the limited term provision of the Fund's Charter is amended by the Board and stockholders in accordance with Maryland law and the Fund's Charter, or unless the Fund completes an Eligible Tender Offer and converts to perpetual existence, the Fund intends to terminate on or about the Termination Date (as such date may be extended by the Board in accordance with the Fund's Charter). The Fund is not a so called "target date" or "life cycle" fund whose asset allocation becomes more conservative over time as its target date, often associated with retirement, approaches. In addition, the Fund is not a "target term" fund whose investment objective is to return its original NAV on the Termination Date. The Fund's investment objectives and policies are not designed to seek to return to investors that purchase common shares in this offering their initial investment of $20.00 per share on the Termination Date or in an Eligible Tender Offer, and such investors and investors that purchase shares after the completion of this offering may receive more or less than their original investment upon termination or in an Eligible Tender Offer.**

Because the assets of the Fund will be liquidated in connection with the termination, the Fund will incur transaction costs in connection with dispositions of portfolio securities. The Fund does not limit its investments to securities having a maturity date prior to the Termination Date and may

Pioneer Municipal High Income Opportunities Fund, Inc. \| Annual \| 4/30/2567

------

[**Table of Contents**](#JOB_Amund_24b87121-7720-4859-9c42-d1ef94d3c34b_TOC)

be required to sell portfolio securities when it otherwise would not, including at times when market conditions are not favorable, which may cause the Fund to lose money. In particular, the Fund's portfolio may still have large exposures to illiquid securities as the Termination Date approaches, and losses due to portfolio liquidation may be significant. During the wind-down period, beginning one year before the Termination Date, the Fund may begin liquidating all or a portion of the Fund's portfolio, and may deviate from its investment policies and may not achieve its investment objectives. During the wind-down period, the Fund's portfolio composition may change as more of its portfolio holdings are called or sold and portfolio holdings are disposed of in anticipation of liquidation. The disposition of portfolio investments by the Fund could cause market prices of such instruments, and hence the NAV and market price of the common shares, to decline. In addition, disposition of portfolio investments will cause the Fund to incur increased brokerage and related transaction expenses. The Fund may receive proceeds from the disposition of portfolio investments that are less than the valuations of such investments by the Fund. Rather than reinvesting the proceeds of matured, called or sold securities, the Fund may invest such proceeds in short-term or other lower yielding securities or hold the proceeds in cash, which may adversely affect its performance and the market price of the common shares. The Fund may distribute the proceeds in one or more liquidating distributions prior to the final liquidation, which may cause fixed expenses to increase when expressed as a percentage of assets under management. Upon a termination, it is anticipated that the Fund will have distributed substantially all of its net assets to common stockholders, although securities for which no market exists or securities trading at depressed prices, if any, may be placed in a liquidating trust. Such a liquidating trust will not register as an investment company under the 1940 Act. As a result, the holders of the interests in the liquidating trust will not receive the protections under the 1940 Act that are afforded to investors in registered investment companies. Stockholders will bear the costs associated with establishing and maintaining a liquidating trust, if necessary. Securities placed in a liquidating trust may be held for an indefinite period of time until they can be sold or pay out all of their cash flows. Additionally, the tax treatment of the liquidating trust's assets may differ from the tax treatment applicable to such assets when held by the Fund. To the extent the costs associated with a liquidating trust exceed the value of the remaining securities, the liquidating trust trustees may determine to dispose of the remaining securities in a manner of their choosing. The Fund cannot predict the amount, if any, of securities that will be required to be placed in a liquidating trust.

If the Fund conducts an Eligible Tender Offer, the Fund may be required to dispose of portfolio investments in connection with any reduction in the Fund's outstanding leverage necessary in order to maintain the Fund's desired leverage ratios following a tender offer. The risks related to the disposition of securities in connection with the Fund's termination also would be present in connection with the disposition of securities in connection with an Eligible Tender Offer. In addition, the Fund's purchase of tendered common shares pursuant to a tender offer will have tax consequences for tendering stockholders and may have tax consequences for non-tendering stockholders. All common stockholders remaining after a tender offer will be subject to proportionately higher expenses due to the reduction in the Fund's total assets. The reduction in the Fund's total assets may also result in less investment flexibility, reduced diversification and greater volatility for the Fund and the common shares, and may have an adverse effect on the Fund's investment performance.

The Adviser may have a conflict of interest in recommending to the Board that the Termination Date be eliminated and the Fund have a perpetual existence. The Fund is not required to conduct additional tender offers following an Eligible Tender Offer and conversion to perpetual existence. Therefore, remaining common stockholders may not have another opportunity to participate in a tender offer. Shares of closed-end management investment companies frequently trade at a discount from their NAV, and as a result remaining stockholders may only be able to sell their common shares at a discount to NAV.

**Market risk. The market prices of securities or other assets held by the Fund may go up or down, sometimes rapidly or unpredictably, due to general market conditions, such as real or perceived adverse economic, political, or regulatory conditions, political instability, recessions, inflation, changes in interest or currency rates, lack of liquidity in the bond markets, the spread of infectious illness or other public health issues, weather or climate events, armed conflict, market disruptions caused by tariffs, trade disputes, sanctions or other government actions, or other factors or adverse investor sentiment. If the market prices of the Fund's securities and assets fall, the value of your investment will go down. A change in financial condition or other event affecting a single issuer or market may adversely impact securities markets as a whole.**

Changes in market conditions may not have the same impact on all types of securities. The value of securities may also fall due to specific conditions that affect a particular sector of the securities market or a particular issuer. In the past decade, financial markets throughout the world have experienced increased volatility, depressed valuations, decreased liquidity and heightened uncertainty. Governmental and non-governmental issuers

[**Table of Contents**](#JOB_Amund_24b87121-7720-4859-9c42-d1ef94d3c34b_TOC)

have defaulted on, or been forced to restructure, their debts. These conditions may continue, recur, worsen or spread. Events that have contributed to these market conditions include, but are not limited to, major cybersecurity events; geopolitical events (including wars, terror attacks and economic sanctions); measures to address budget deficits; downgrading of sovereign debt; changes in oil and commodity prices; dramatic changes in currency exchange rates; global pandemics; and public sentiment. Some sectors of the economy and individual issuers have experienced or may experience particularly large losses. Periods of extreme volatility in the financial markets; reduced liquidity of many instruments; increased government debt, inflation and disruptions to supply chains, consumer demand and employee availability, may continue for some time.

Raising the ceiling on U.S. government debt has become increasingly politicized. Any failure to increase the total amount that the U.S. government is authorized to borrow could lead to a default on U.S. government obligations, with unpredictable consequences for economies and markets in the U.S. and elsewhere. Inflation and interest rates may increase. These circumstances could adversely affect the value and liquidity of the Fund's investments and negatively impact the Fund's performance. In addition, inflation, rising interest rates, global supply chain disruptions and other market events could adversely affect the companies or issuers in which the Fund invests. Following Russia's invasion of Ukraine, Russian securities lost all, or nearly all, their market value. Other securities or markets could be similarly affected by past or future political, geopolitical or other events or conditions.

Governments and central banks, including the U.S. Federal Reserve, have taken extraordinary and unprecedented actions to support local and global economies and the financial markets. These actions have resulted in significant expansion of public debt, including in the U.S. The consequences of high public debt, including its future impact on the economy and securities markets, may not be known for some time. U.S. Federal Reserve or other U.S. or non-U.S. governmental or central bank actions, including increases or decreases in interest rates, or contrary actions by different governments, could negatively affect financial markets generally, increase market volatility and reduce the value and liquidity of securities in which the Fund invests. Policy and legislative changes in the U.S. and in other countries are affecting many aspects of financial regulation, and these and other events affecting global markets, such as the United Kingdom's exit from the European Union (or Brexit), potential trade imbalances with China or other countries, or sanctions or other government actions against Russia, other nations or individuals or companies (or their countermeasures), may contribute to decreased liquidity and increased volatility in the financial

[**Table of Contents**](#JOB_Amund_24b87121-7720-4859-9c42-d1ef94d3c34b_TOC)

markets. The impact of these changes on the markets, and the implications for market participants, may not be fully known for some time.

The U.S. and other countries are periodically involved in disputes over trade and other matters, which may result in tariffs, investment restrictions and adverse impacts on affected companies and securities. For example, the U.S. has imposed tariffs and other trade barriers on Chinese exports, has restricted sales of certain categories of goods to China, and has established barriers to investments in China. Trade disputes may adversely affect the economies of the U.S. and its trading partners, as well as companies directly or indirectly affected and financial markets generally. The U.S. government has prohibited U.S. persons, such as the Fund, from investing in Chinese companies designated as related to the Chinese military. The Chinese government is involved in a longstanding dispute with Taiwan that has included threats of invasion. If the political climate between the U.S. and China does not improve or continues to deteriorate, if China were to attempt unification of Taiwan by force, or if other geopolitical conflicts develop or get worse, economies, markets and individual securities may be severely affected both regionally and globally, and the value of the Fund's assets may go down.

Economies and financial markets throughout the world are increasingly interconnected. Economic, financial or political events, trading and tariff arrangements, armed conflict such as between Russia and Ukraine or in the Middle East, terrorism, natural disasters, infectious illness or public health issues, cybersecurity events, supply chain disruptions, sanctions against Russia, other nations or individuals or companies and possible countermeasures, and other circumstances in one country or region could have profound impacts on other countries or regions and on global economies or markets. As a result, whether or not the Fund invests in securities of issuers located in or with significant exposure to the countries or regions directly affected, the value and liquidity of the Fund's investments may be negatively affected. The Fund may experience a substantial or complete loss on any security or derivative position.

**Municipal securities risk. The municipal bond market can be susceptible to unusual volatility, particularly for lower-rated and unrated securities. Liquidity can be reduced unpredictably in response to overall economic conditions or credit tightening. Issuers of municipal securities tend to derive a significant portion of their revenue from taxes, particularly property and income taxes, and decreases in personal income levels and property values and other unfavorable economic factors, such as a general economic recession, adversely affect municipal securities. Municipal issuers may also be adversely affected by rising health care costs, increasing unfunded pension liabilities and by the phasing out of federal programs**

Pioneer Municipal High Income Opportunities Fund, Inc. \| Annual \| 4/30/2571

[**Table of Contents**](#JOB_Amund_24b87121-7720-4859-9c42-d1ef94d3c34b_TOC)

providing financial support. Where municipal securities are issued to finance particular projects, especially those relating to education, health care, transportation, housing, water or sewer and utilities, issuers often depend on revenues from those projects to make principal and interest payments. Adverse conditions and developments in those sectors can result in lower revenues to issuers of municipal securities, potentially resulting in defaults, and can also have an adverse effect on the broader municipal securities market. To the extent the Fund invests significantly in a single state, or in securities the payments on which are dependent upon a single project or source of revenues, or that relate to a sector or industry, including health care facilities, education, special revenues and housing, the Fund will be more susceptible to associated risks and developments.

There may be less public information available on municipal issuers or projects than other issuers, and valuing municipal securities may be more difficult. In addition, the secondary market for municipal securities is less well developed and liquid than other markets, and dealers may be less willing to offer and sell municipal securities in times of market turbulence. Changes in the financial condition of one or more individual municipal issuers (or one or more insurers of municipal issuers), or one or more defaults by municipal issuers or insurers, can adversely affect liquidity and valuations in the overall market for municipal securities. The value of municipal securities can also be adversely affected by regulatory and political developments affecting the ability of municipal issuers to pay interest or repay principal, actual or anticipated tax law changes or other legislative actions, and by uncertainties and public perceptions concerning these and other factors. Municipal securities may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. Financial difficulties of municipal issuers may continue or get worse, particularly in the event of political, economic or market turmoil or a recession.

The rate of interest paid on municipal securities normally is lower than the rate of interest paid on fully taxable securities. Some municipal securities, such as general obligation issues, are backed by the issuer's taxing authority, while other municipal securities, such as revenue issues, are backed only by revenues from certain facilities or other sources and not by the issuer itself. The payment of principal and interest on private activity and industrial development revenue bonds is solely dependent on the ability of the facility's user to meet its financial obligations and the pledge, if any, of the facility or other property as security for payment.

The municipal market can be susceptible to unusual volatility, particularly for lower-rated and unrated securities.

[**Table of Contents**](#JOB_Amund_24b87121-7720-4859-9c42-d1ef94d3c34b_TOC)

**Taxable investment risk. Although distributions of interest income from the Fund's tax-exempt securities are generally exempt from regular federal income tax, distributions from other sources, including capital gain distributions, and any gains on the sale of your shares are not. In addition, the interest on the Fund's municipal securities could become subject to regular federal income tax or the AMT due to noncompliant conduct by issuers, unfavorable legislation or litigation, or adverse interpretations by regulatory authorities. You should consult a tax Adviser about whether the AMT applies to you and about state and local taxes on your Fund distributions.**

**"High yield" or "junk" bond risk. Debt securities that are below investment grade, called "junk bonds," are speculative, have a higher risk of default or are already in default, tend to be less liquid and are more difficult to value than higher grade securities and may involve major risk of exposure to adverse conditions and negative sentiments. These securities have a higher risk of issuer default because, among other reasons, issuers of junk bonds often have more debt in relation to total capitalization than issuers of investment grade securities. Junk bonds tend to be volatile and more susceptible to adverse events and negative sentiments. These risks are more pronounced for securities that are already in default. The Fund may not receive interest payments on defaulted securities and may incur costs to protect its investment. In addition, defaulted securities involve the substantial risk that principal will not be repaid. Changes in economic conditions or developments regarding the individual issuer are more likely to cause price volatility and weaken the capacity of such securities to make principal and interest payments than is the case for higher grade debt securities. The value of lower-quality debt securities often changes in response to issuer, political, or economic developments and can decline significantly over short as well as long periods of time or during periods of general or regional economic difficulty. Junk bonds may also be less liquid than higher-rated securities, which means that the Fund may have difficulty selling them at times, and it may have to apply a greater degree of judgment in establishing a price for purposes of valuing Fund shares. Junk bonds generally are issued by less creditworthy issuers. Issuers of junk bonds may have a larger amount of outstanding debt securities relative to their assets than issuers of investment grade bonds. In the event of an issuer's bankruptcy, claims of other creditors may have priority over the claims of junk bond holders, leaving few or no assets available to repay junk bond holders. The Fund may incur expenses to the extent necessary to seek recovery upon default or to negotiate new terms with a defaulting issuer. Junk bonds frequently have redemption features that permit an issuer to repurchase the security from the Fund before it matures. If the**

issuer redeems junk bonds, the Fund may have to invest the proceeds in bonds with lower yields and may lose income.

**Interest rate risk. The market prices of the Fund's fixed income securities may fluctuate significantly when interest rates change. The value of your investment will generally go down when interest rates rise. A rise in rates tends to have a greater impact on the prices of longer term or duration securities. For example, if interest rates increase by 1%, the value of a Fund's portfolio with a portfolio duration of ten years would be expected to decrease by 10%, all other things being equal. A general rise in interest rates could adversely affect the price and liquidity of fixed income securities. The maturity of a security may be significantly longer than its effective duration. A security's maturity and other features may be more relevant than its effective duration in determining the security's sensitivity to other factors affecting the issuer or markets generally, such as changes in credit quality or in the yield premium that the market may establish for certain types of securities (sometimes called "credit spread"). In general, the longer its maturity the more a security may be susceptible to these factors. When the credit spread for a fixed income security goes up, or "widens," the value of the security will generally go down.**

Rising interest rates can lead to increased default rates, as issuers of floating rate securities find themselves faced with higher payments. Unlike fixed rate securities, floating rate securities generally will not increase in value if interest rates decline. Changes in interest rates also will affect the amount of interest income the Fund earns on its floating rate investments.

**Credit risk. If an issuer or guarantor of a security held by the Fund or a counterparty to a financial contract with the Fund defaults on its obligation to pay principal and/or interest, has its credit rating downgraded or is perceived to be less creditworthy, or the credit quality or value of any underlying assets declines, the value of your investment will typically decline. Changes in actual or perceived creditworthiness may occur quickly. The Fund could be delayed or hindered in its enforcement of rights against an issuer, guarantor or counterparty.**

**Prepayment or call risk. Many issuers have a right to prepay their securities. If interest rates fall, an issuer may exercise this right. If this happens, the Fund will not benefit from the rise in market price that normally accompanies a decline in interest rates, and will be forced to reinvest prepayment proceeds at a time when yields on securities available in the market are lower than the yield on the prepaid security. The Fund also may lose any premium it paid on the security.**

#### Extension risk. During periods of rising interest rates, the average life of certain types of securities may be extended because of slower than

------

[**Table of Contents**](#JOB_Amund_24b87121-7720-4859-9c42-d1ef94d3c34b_TOC)

expected principal payments. This may lock in a below market interest rate, increase the security's duration and reduce the value of the security.

**Risk of illiquid investments. Certain securities and derivatives held by the Fund may be impossible or difficult to purchase, sell or unwind. Illiquid securities and derivatives also may be difficult to value. Liquidity risk may be magnified in an environment of rising interest rates or widening credit spreads. During times of market turmoil, there have been, and may be, no buyers or sellers for securities in entire asset classes. If the Fund is forced to sell an illiquid asset or unwind a derivatives position, the Fund may suffer a substantial loss or may not be able to sell at all.**

**Portfolio selection risk. The Adviser's judgment about the quality, relative yield, relative value or market trends affecting a particular sector or region, market segment, security, industry or about interest rates or other market factors may prove to be incorrect or may not produce the desired results, or there may be imperfections, errors or limitations in the models, tools and information used by the Adviser.**

**Small and mid-size issuers risk. Compared with those of larger municipal issuers, securities of small and mid-size municipal issuers may experience sharper swings in market values, have limited liquidity, be harder to value or to sell at the times and prices the Adviser thinks appropriate, and offer greater potential for gain and loss.**

**Risks of subordinated securities. A holder of securities that are subordinated or "junior" to more senior securities of an issuer is entitled to payment after holders of more senior securities of the issuer. Subordinated securities are more likely to suffer a credit loss than non-subordinated securities of the same issuer, any loss incurred by the subordinated securities is likely to be proportionately greater, and any recovery of interest or principal may take more time. As a result, even a perceived decline in creditworthiness of the issuer is likely to have a greater impact on subordinated securities than more senior securities.**

**Debtor-in-possession financings risk. Debtor-in-possession financings are loans to a debtor-in-possession in a proceeding under the U.S. Bankruptcy Code that have been approved by the bankruptcy court. These financings allow the entity to continue its business operations while reorganizing under Chapter 11 of the U.S. Bankruptcy Code. Debtor-in-possession financings can provide creditors with varying levels of protection, as they may carry super-priority repayment status, be secured by a lien on the borrower's otherwise unencumbered assets, or be secured by a junior lien on the borrower's encumbered assets. These financings are subject to the risk that the borrower will not emerge successfully from the bankruptcy/reorganization proceedings and will be forced to liquidate its**

assets. In the event of liquidation, the Fund's only recourse will be against the property securing the debtor-in-possession loan and any remaining unencumbered assets, which might be insufficient to repay the debtor-in-possession loan in full.

**U.S. Treasury obligations risk. The market value of direct obligations of the U.S. Treasury may vary due to changes in interest rates. In addition, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund's investments in obligations issued by the U.S. Treasury to decline.**

**U.S. government agency obligations risk. The Fund invests in obligations issued by agencies and instrumentalities of the U.S. government. Government-sponsored entities such as the Federal National Mortgage Association ("FNMA"), the Federal Home Loan Mortgage Corporation ("FHLMC") and the Federal Home Loan Banks ("FHLBs"), although chartered or sponsored by Congress, are not funded by congressional appropriations and the debt and mortgage-backed securities issued by them are neither guaranteed nor issued by the U.S. government. The maximum potential liability of the issuers of some U.S. government obligations may greatly exceed their current resources, including any legal right to support from the U.S. government. Such debt and mortgage-backed securities are subject to the risk of default on the payment of interest and/or principal, similar to debt of private issuers. Although the U.S. government has provided financial support to FNMA and FHLMC in the past, there can be no assurance that it will support these or other government-sponsored entities in the future.**

**Mortgage-related and asset-backed securities risk. The value of mortgage-related securities, including commercial mortgage-backed securities, collateralized mortgage-backed securities, credit risk transfer securities, and asset-backed securities, will be influenced by factors affecting the assets underlying such securities. As a result, during periods of declining asset value, difficult or frozen credit markets, swings in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. Mortgage-backed securities tend to be more sensitive to changes in interest rate than other types of debt securities. These securities are also subject to interest rate, prepayment and extension risks. Some of these securities may receive little or no collateral protection from the underlying assets and are thus subject to the risk of default. The risk of such defaults is generally higher in the case of mortgage-backed investments offered by non-governmental issuers and those that include so-called "sub-prime" mortgages. The structure of some of these securities may be complex and there may be less available**

information than for other types of debt securities. Upon the occurrence of certain triggering events or defaults, the Fund may become the holder of underlying assets at a time when those assets may be difficult to sell or may be sold only at a loss.

**Risks of investing in collateralized debt obligations. Investment in a collateralized debt obligation (CDO) is subject to the credit, subordination, interest rate, valuation, prepayment, extension and other risks of the obligations underlying the CDO and the tranche of the CDO in which the Fund invests. CDOs are subject to liquidity risk. CDOs carry additional risks including, but not limited to: (i) the possibility that distributions from collateral securities will not be adequate to make interest or other payments; (ii) the risk that the collateral may default or decline in value or be downgraded, if rated by a nationally recognized statistical rating organization; (iii) the structure and complexity of the transaction and the legal documents could lead to disputes among investors regarding the characterization of proceeds; (iv) the investment return achieved by the Fund could be significantly different than those predicted by financial models; (v) the lack of a readily available secondary market for CDOs; (vi) the risk of forced "fire sale" liquidation due to technical defaults such as coverage test failures; and (vii) the CDO's manager may perform poorly. In addition, investments in CDOs may be characterized by the Fund as illiquid securities. CDOs may be highly leveraged (which could make them highly volatile). Synthetic CDOs are also subject to the risks of investing in derivatives, such as credit default swaps, and leverage risk. The Fund may invest in or be exposed to CDOs that are sometimes referred to as "covenant-lite" obligations, which generally are debt obligations that lack financial maintenance covenants or possess fewer or contingent financial maintenance covenants and other financial protections for lenders and investors. These "covenant-lite" obligations typically are particularly subject to the risks associated with investments in loans.**

**Risks of instruments that allow for balloon payments or negative amortization payments. Certain debt instruments allow for balloon payments or negative amortization payments. Such instruments permit the borrower to avoid paying currently a portion of the interest accruing on the instrument. While these features make the debt instrument more affordable to the borrower in the near term, they increase the risk that the borrower will be unable to make the resulting higher payment or payments that become due at the maturity of the loan.**

**Derivatives risk. Using synthetic municipal securities, inverse floating rate obligations, credit default swaps and other derivatives can increase Fund losses and reduce opportunities for gains when market prices, interest rates or the derivative instruments themselves behave in a way not anticipated**

Pioneer Municipal High Income Opportunities Fund, Inc. \| Annual \| 4/30/2577

[**Table of Contents**](#JOB_Amund_24b87121-7720-4859-9c42-d1ef94d3c34b_TOC)

by the Fund. Using derivatives may increase the volatility of the Fund's net asset value and may not provide the result intended. Derivatives may have a leveraging effect on the Fund. Some derivatives have the potential for unlimited loss, regardless of the size of the Fund's initial investment. Derivatives are generally subject to the risks applicable to the assets, rates, indices or other indicators underlying the derivative. Changes in a derivative's value may not correlate well with the referenced asset or metric. The Fund also may have to sell assets at inopportune times to satisfy its obligations. Derivatives may be difficult to sell, unwind or value, and the counterparty may default on its obligations to the Fund. Use of derivatives may have different tax consequences for the Fund than an investment in the underlying security, and such differences may affect the amount, timing and character of income distributed to stockholders. The U.S. government and foreign governments have adopted and implemented or are in the process of adopting and implementing regulations governing derivatives markets, including mandatory clearing of certain derivatives, margin and reporting requirements. The ultimate impact of the regulations remains unclear. Additional regulation of derivatives may make them more costly, limit their availability or utility, otherwise adversely affect their performance or disrupt markets.

**Synthetic municipal securities risk. The tax-exempt character of the interest paid on tender option bonds, bond receipts and similar synthetic municipal securities, a type of derivative instrument, is based on the tax-exempt income stream from the collateral. In addition to the risks of investing in municipal securities and in derivatives generally, investments in synthetic municipal securities are subject to the risk that income derived from such securities is deemed to be taxable.**

**Risks of investing in inverse floating rate obligations. The interest rate on inverse floating rate obligations will generally decrease as short-term interest rates increase, and increase as short-term rates decrease. Due to their leveraged structure, the sensitivity of the market value of an inverse floating rate obligation to changes in interest rates is generally greater than a comparable long-term bond issued by the same issuer and with similar credit quality, redemption and maturity provisions. Inverse floating rate obligations may be volatile and involve leverage risk.**

**Credit default swap risk. Credit default swap contracts, a type of derivative instrument, involve special risks and may result in losses to the Fund. Credit default swaps may in some cases be illiquid, and they increase credit risk since the Fund has exposure to the issuer of the referenced obligation and either the counterparty to the credit default swap or, if it is a cleared transaction, the brokerage firm through which the trade was cleared and the clearing organization that is the counterparty to that trade.**

**Structured securities risk Structured securities may behave in ways not anticipated by the Fund, or they may not receive the tax, accounting or regulatory treatment anticipated by the Fund.**

**Leverage risk. When the Fund uses leverage through issuing preferred shares or borrowing or otherwise engages in transactions that have a leveraging effect on the Fund's portfolio, the value of the Fund will be more volatile and all other risks will tend to be compounded. This is because leverage generally magnifies the effect of any increase or decrease in the value of the Fund's underlying assets or creates investment risk with respect to a larger pool of assets than the Fund would otherwise have, potentially resulting in the loss of all assets. Engaging in such transactions may cause the Fund to liquidate positions when it may not be advantageous to do so. New derivatives regulations require the Fund, to the extent it uses derivatives to a material extent, to, among other things, comply with certain overall limits on leverage. These regulations may limit the ability of the Fund to pursue its investment strategies and may not be effective to mitigate the Fund's risk of loss from derivatives.**

The Fund may use financial leverage on an ongoing basis for investment purposes by borrowing from banks through a revolving credit facility and by engaging in certain other forms of leverage, including investments in inverse floating rate securities. The fees and expenses attributed to leverage, including any increase in the management fees, will be borne by holders of common shares. Since the Adviser's fee is based on a percentage of the Fund's managed assets, its fee will be higher if the Fund is leveraged, and the Adviser will thus have an incentive to leverage the Fund.

**Risks of zero coupon bonds, payment in kind, deferred and contingent payment securities. These securities may be more speculative and may fluctuate more in value than securities which pay income periodically and in cash. In addition, although the Fund receives no periodic cash payments on such securities, the Fund is deemed for tax purposes to receive income from such securities, which applicable tax rules require the Fund to distribute to stockholders. Such distributions may be taxable when distributed to stockholders.**

**Repurchase agreement risk. In the event that the other party to a repurchase agreement defaults on its obligations, the Fund may encounter delay and incur costs before being able to sell the security. Such a delay may involve loss of interest or a decline in price of the security. In addition, if the Fund is characterized by a court as an unsecured creditor, it would be at risk of losing some or all of the principal and interest involved in the transaction.**

[**Table of Contents**](#JOB_Amund_24b87121-7720-4859-9c42-d1ef94d3c34b_TOC)

**Market segment risk. To the extent the Fund emphasizes, from time to time, investments in a market segment, the Fund will be subject to a greater degree to the risks particular to that segment, and may experience greater market fluctuation than a fund without the same focus.**

**Valuation risk. Nearly all of the Fund's investments are valued using a fair value methodology. The sales price the Fund could receive for any particular portfolio investment may differ from the Fund's valuation of the investment, particularly for illiquid securities and securities that trade in thin or volatile markets. These differences may increase significantly and affect Fund investments more broadly during periods of market volatility. The ability to value the Fund's investments may also be impacted by technological issues and/or errors by pricing services or other third party service providers.**

**Cybersecurity risk. Cybersecurity failures by and breaches of the Fund's Adviser, transfer agent, custodian, Fund accounting agent or other service providers may disrupt Fund operations, interfere with the Fund's ability to calculate its NAV, prevent Fund stockholders from purchasing or selling shares or receiving distributions or receiving timely information regarding the Fund or their investment in the Fund, cause loss of or unauthorized access to private stockholder information, and result in financial losses to the Fund and its stockholders, regulatory fines, penalties, reputational damage, or additional compliance costs. New ways to carry out cyber attacks continue to develop. Therefore, there is a chance that some risks have not been identified or prepared for, or that an attack may not be detected, which puts limitations on the Fund's ability to plan for or respond to a cyber attack.**

**Cash management risk. The value of the investments held by the Fund for cash management or temporary defensive purposes may be affected by market risks, changing interest rates and by changes in credit ratings of the investments. To the extent that the Fund has any uninvested cash, the Fund would be subject to credit risk with respect to the depository institution holding the cash. If the Fund holds cash uninvested, the Fund will not earn income on the cash and the Fund's yield will go down. During such periods, it may be more difficult for the Fund to achieve its investment objectives.**

**Anti-takeover provisions. The Fund's Charter and Bylaws include provisions that are designed to limit the ability of other entities or persons to acquire control of the Fund for short-term objectives, including by converting the Fund to open-end status or changing the composition of the Board, that may be detrimental to the Fund's ability to achieve its primary investment objective of seeking to provide its common stockholders with a**

high level of current income exempt from regular federal income tax. These provisions include staggered terms of service for the Directors, advance notice requirements for stockholder proposals, and super-majority voting requirements for certain transactions with affiliates, open-ending the Fund or a merger, liquidation, asset sale or similar transaction.

Exclusive forum provisions. The Fund's Bylaws designate the Circuit Court for Baltimore City, Maryland as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by the Fund's stockholders and provide that claims relating to causes of action under the United States federal securities laws may only be brought in the United States District Court for the District of Maryland, Northern Division, which could limit stockholders' ability to obtain a favorable judicial forum for disputes with the Fund or its directors, officers or the Fund's agents, if any, and could discourage lawsuits against the Fund and its directors, officers and agents, if any.

The Fund's Bylaws provide that, unless the Fund consents in writing to the selection of an alternative forum, the Circuit Court for Baltimore City, Maryland, or, if that court does not have jurisdiction, the United States District Court for the District of Maryland, Northern Division, will be the sole and exclusive forum for (a) any Internal Corporate Claim, as such term is defined in the MGCL, (b) any derivative action or proceeding brought on the Fund's behalf (other than actions arising under federal securities laws), (c) any action asserting a claim of breach of any duty owed by any of the Fund's directors, officers or other agents to the Fund or to the Fund's stockholders, (d) any action asserting a claim against the Fund or any of the Fund's directors, officers or other agents arising pursuant to any provision of the MGCL or the Fund's Charter or Bylaws or (e) any other action asserting a claim against the Fund or any of the Fund's directors, officers or other agents that is governed by the internal affairs doctrine. Furthermore, the Fund's Bylaws provide that, unless the Fund consents in writing to the selection of an alternative forum, the United States District Court for the District of Maryland, Northern Division shall, to the fullest extent permitted by law, be the sole and exclusive forum for the resolution of any claim arising under the United States federal securities laws.

These exclusive forum provisions may limit the ability of the Fund's stockholders to bring a claim in a judicial forum that such stockholders find favorable for disputes with the Fund or the Fund's directors, officers, or agents, if any, which may discourage such lawsuits against the Fund and the Fund's directors, officers, and agents, if any. Alternatively, if a court were to find the choice of forum provisions contained in the Fund's Bylaws to be inapplicable or unenforceable in an action, the Fund may incur additional costs associated with resolving such action in other jurisdictions,

which could materially adversely affect the Fund's business, financial condition, and operating results.

Please note that there are many other factors that could adversely affect your investment and that could prevent the Fund from achieving its goals.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

INVESTMENT RESTRICTIONS

The following are the Fund's fundamental investment restrictions. These restrictions, along with the Fund's investment objectives, may not be changed without the approval of the holders of a majority of the Fund's outstanding voting securities (which for this purpose and under the 1940 Act means the lesser of (i) 67% of the common shares represented at a meeting at which more than 50% of the outstanding common shares are represented or (ii) more than 50% of the outstanding common shares).

The Fund may not:

(1) The Fund may not borrow money except as permitted by (i) the 1940 Act, or interpretations or modifications by the SEC, SEC staff or other authority of competent jurisdiction, or (ii) exemptive or other relief or permission from the SEC, SEC staff or other authority of competent jurisdiction.

(2) The Fund may not engage in the business of underwriting the securities of other issuers except as permitted by (i) the 1940 Act, or interpretations or modifications by the SEC, SEC staff or other authority of competent jurisdiction, or (ii) exemptive or other relief or permission from the SEC, SEC staff or other authority of competent jurisdiction.

Effects of Leverage

The following table is furnished in response to requirements of the Securities and Exchange Commission. It is designed to illustrate the effects of leverage on common share total return, assuming investment portfolio total returns (consisting of income and changes in the value of investments held in the Fund's portfolio) of -10%, -5%, 0%, 5% and 10%. The table below reflects the Fund's borrowings under a credit agreement and certain other forms of leverage, including investments in inverse floating rate securities, as of April 30, 2025 as a percentage of the Fund's total assets (which includes the assets attributable to such leverage), the annual rate of interest on the borrowings as of April 30, 2025, and the annual return that the Fund's portfolio must experience (net of expenses) in order to cover such costs. The information below does not reflect the Fund's use of certain other forms of economic leverage achieved through the use of other instruments or transactions not considered to be senior securities under the 1940 Act, if any.

The assumed investment portfolio returns in the table below are hypothetical figures and are not necessarily indicative of the investment portfolio returns experienced or expected to be experienced by the Fund. Your actual returns may be greater or less than those appearing below. In addition, actual expenses associated with borrowings by the Fund may vary frequently and may be significantly higher or lower than the rate used for the example below.

---

| | |
|:---|:---|
| &nbsp;&nbsp;Borrowings under credit agreement and investments in inverse floating rate securities as a percentage of total managed assets (including assets attributable to borrowings) | 11.11% |
| &nbsp;&nbsp;Annual effective interest rate payable by Fund on borrowings | &nbsp;&nbsp;&nbsp;5.28% |
| &nbsp;&nbsp;Annual return Fund portfolio must experience (net of expenses) to cover interest rate on borrowings | &nbsp;&nbsp;&nbsp;0.59% |
| &nbsp;&nbsp;Common share total return for (10.00)% assumed portfolio total return | &nbsp;&nbsp;(11.91)% |
| &nbsp;&nbsp;Common share total return for (5.00)% assumed portfolio total return | &nbsp;&nbsp;&nbsp;&nbsp;(6.28)% |
| &nbsp;&nbsp;Common share total return for 0.00% assumed portfolio total return | &nbsp;&nbsp;&nbsp;&nbsp;(0.66)% |
| &nbsp;&nbsp;Common share total return for 5.00% assumed portfolio total return | &nbsp;&nbsp;&nbsp;4.97% |
| &nbsp;&nbsp;Common share total return for 10.00% assumed portfolio total return | 10.59% |

---

Common share total return is composed of two elements - investment income net of the Fund's expenses, including any interest/dividends on assets resulting from leverage, and gains or losses on the value of the securities the Fund owns. As required by Securities and Exchange Commission rules, the table assumes that the Fund is more likely to suffer capital losses than to enjoy capital appreciation. For example, to assume a

total return of 0%, the Fund must assume that the income it receives on its investments is entirely offset by losses in the value of those investments.

This table reflects hypothetical performance of the Fund's portfolio and not the performance of the Fund's common shares, the value of which will be determined by market forces and other factors.

Should the Fund elect to add additional leverage to its portfolio, the potential benefits of leveraging the Fund's shares cannot be fully achieved until the proceeds resulting from the use of leverage have been received by the Fund and invested in accordance with the Fund's investment objective and principal investment strategies. The Fund's willingness to use additional leverage, and the extent to which leverage is used at any time, will depend on many factors, including, among other things, the Adviser assessment of the yield curve environment, interest rate trends, market conditions and other factors.

Approval of Renewal of Investment Management Agreement with Amundi Asset Management US, Inc. and Approval of Interim Investment Advisory Agreement with Victory Capital Management Inc.

Effective April 1, 2025, Amundi Asset Management US, Inc. ("Amundi US"), the Fund's previous investment adviser, has been contributed to Victory Capital Holdings, Inc. ("Victory Capital Holdings"), the parent company of Victory Capital Management Inc. ("Victory Capital") (the "Transaction"). As a result of the Transaction, the Fund's investment advisory agreement with Amundi US (the "Amundi US Investment Advisory Agreement") terminated automatically on April 1, 2025.

In connection with the Transaction, the Fund's Board of Directors (the "Board" or the "Directors") approved a new investment advisory agreement with Victory Capital (the "New Investment Advisory Agreement") at a Board meeting held on December 16, 2024, subject to approval by the Fund's stockholders. As of May 1, 2025, the Fund's stockholders had not approved the New Investment Advisory Agreement.

At the December 16, 2024 Board meeting, the Board also approved an interim investment advisory agreement with Victory Capital (the "Interim Investment Advisory Agreement") to take effect upon the closing of the Transaction in the event that additional time was needed to solicit stockholder approval of the New Investment Advisory Agreement.

The Board's considerations in approving the New Investment Advisory Agreement and the Interim Investment Advisory Agreement are discussed below.

Board Evaluation of the New Investment Advisory Agreement and Interim Investment Advisory Agreement

The Board evaluated the Transaction and the New Investment Advisory Agreement and Interim Investment Advisory Agreement for the Fund.

At in-person meetings held on May 14-15, 2024, July 22-23, 2024, September 16-17, 2024, November 12-13, 2024, and December 16, 2024, the Board met to consider the Transaction, including the plan to contribute Amundi US to Victory Capital Holdings in exchange for Amundi Asset Management S.A.S. ("Amundi") becoming a significant shareholder of Victory Capital Holdings, and to establish a long-term reciprocal distribution partnership between Amundi and Victory Capital. The Board was advised that the Transaction, if completed, would constitute a change

of control under the 1940 Act that would result in the termination of the Amundi US Investment Advisory Agreement.

At these meetings, which included meetings of the full Board and separate meetings of the Independent Directors, and at video conferences of the Independent Directors held on May 23, 2024, June 24, 2024, August 19, 2024, October 29, 2024 and December 9, 2024, the Board or the Independent Directors, as the case may be, considered, among other things, whether it would be in the best interests of the Fund and its stockholders to approve the New Investment Advisory Agreement. To assist the Board in its consideration of the New Investment Advisory Agreement and the anticipated impacts of the Transaction on the Fund and its stockholders, Victory Capital provided materials and information about Victory Capital, including its financial condition and asset management capabilities and organization, and Victory Capital and Amundi provided materials and information about the proposed Transaction between Victory Capital and Amundi.

To assist the Board in its consideration of the New Investment Advisory Agreement, Victory Capital provided extensive information to the Board regarding the Transaction and the investment advisory services to be provided by Victory Capital under the New Investment Advisory Agreement. Before and during the December 16, 2024 meeting, the Board sought additional information as it deemed necessary and appropriate. In connection with their consideration of the New Investment Advisory Agreement, the Independent Directors worked with their independent legal counsel to prepare requests for additional information that were submitted to Victory Capital and Amundi US. The Board's requests for information sought information relevant to the Board's consideration of the New Investment Advisory Agreement and other anticipated impacts of the Transaction on the Fund and its stockholders. In addition, the Board formed a Transaction Sub-Committee, comprised solely of Independent Directors, to assist the Board in its consideration of the New Investment Advisory Agreement and the Transaction. The Board and the Transaction Sub-Committee met with senior management representatives of Victory Capital and Amundi US on numerous occasions to discuss various aspects of the Transaction, to review information provided to assist the Board in its consideration of the New Investment Advisory Agreement and the Transaction, and to make supplemental due diligence requests for additional information from Victory Capital and Amundi US with respect to the New Investment Advisory Agreement and the Transaction. Victory Capital and Amundi US provided documents and information in response to the requests from the Board and the Transaction Sub-Committee, as well as

made presentations to, and responded to questions from, the Board and the Transaction Sub-Committee at various meetings.

Prior to voting on the New Investment Advisory Agreement, the Independent Directors reviewed the Transaction and the New Investment Advisory Agreement with representatives of Amundi US and Victory Capital, counsel to the Fund and counsel to the Independent Directors. The Independent Directors also reviewed the Transaction and the New Investment Advisory Agreement with their counsel in private sessions at which no representatives of Amundi US, Victory Capital or counsel to the Fund were present.

The Board's evaluation of the New Investment Advisory Agreement reflected the information provided specifically in connection with its review of the New Investment Advisory Agreement, as well as, where relevant, information that was previously furnished to the Board in connection with the renewal of the Amundi US Investment Advisory Agreement at in-person meetings held on September 17, 2024 and at other Board meetings throughout the prior year.

Among other things, the Directors considered:

expense limitation in effect at the time of: (1) the original waiver or expense reimbursement; or (2) recoupment, after giving effect to the recoupment amount;

Certain of these considerations are discussed in more detail below.

The Directors also requested, obtained and considered the following information in connection with their evaluation of the Transaction and the New Investment Advisory Agreement for the Fund: (i) memoranda provided by Fund counsel that summarized the legal standards and other considerations that are relevant to the Directors in their deliberations regarding the New Investment Advisory Agreement; and (ii) the Fund's advisory fees and total expense ratios, the financial statements of Victory Capital, a profitability analysis provided by Victory Capital, and an analysis from Victory Capital as to possible economies of scale. The Directors further considered, materials provided in connection with their review of the Amundi US Investment Advisory Agreement, including, for the Fund, information regarding the qualifications of the investment management teams for the Fund, as well as the level of investment by the Fund's portfolio managers in the Fund. In addition, the Directors considered the information provided at regularly scheduled meetings throughout the year regarding the Fund's performance and risk attributes, including

------

[**Table of Contents**](#JOB_Amund_24b87121-7720-4859-9c42-d1ef94d3c34b_TOC)

through meetings with investment management personnel, and took into account other information related to the Fund provided to the Directors at regularly scheduled meetings.

At the December 16, 2024, meeting, based on their evaluation of the information provided by Victory Capital and Amundi US, the Directors including the Independent Directors voting separately, approved the New Investment Advisory Agreement and the Interim Investment Advisory Agreement for the Fund. In considering the New Investment Advisory Agreement for the Fund, the Directors considered various factors that they determined were relevant, including the factors described below. The Directors did not identify any single factor as the controlling factor in their determinations. The Directors considered the same factors with respect to the Interim Investment Advisory Agreement for the Fund.

Nature, Extent and Quality of Services.

The Directors considered the nature, extent and quality of the services that had been provided by Amundi US to the Fund and that were expected to be provided by Victory Capital to the Fund following the consummation of the Transaction, taking into account the investment objective(s) and principal investment strategies of the Fund.

The Board considered information provided by Victory Capital regarding its business and operating structure, scale of operations, leadership and reputation. The Board also considered the capabilities, resources, and personnel of Victory Capital, in order to determine whether Victory Capital was capable of providing the same level of investment management services provided to the Fund by Amundi US. The Board received information regarding Victory Capital's plans to integrate Amundi US investment personnel into Victory Capital as members of Pioneer Investments, a Victory Capital investment franchise. The Board noted that it had considered the qualifications of the portfolio managers at Amundi US at its September 17, 2024 Meeting.

The Directors considered Victory Capital's representation that there would be no change to the investment approach under which the Fund would be managed under the New Investment Advisory Agreement.

The Board considered the non-investment resources, infrastructure and personnel of Victory Capital that would be involved in Victory Capital's services to the Fund, including Victory Capital's compliance, risk management, cybersecurity and legal resources and personnel. The Board also reviewed information provided by Victory Capital related to its business, legal, and regulatory affairs, including information regarding the resources available to Victory Capital to provide the services specified

Pioneer Municipal High Income Opportunities Fund, Inc. \| Annual \| 4/30/2591

------

[**Table of Contents**](#JOB_Amund_24b87121-7720-4859-9c42-d1ef94d3c34b_TOC)

under the New Investment Advisory Agreement. The Board also considered Victory Capital's financial condition, and noted that Victory Capital was expected to be able to provide a high level of service to the Fund and continuously invest and re-invest in its investment management business.

The Directors considered that Amundi US previously supervised and monitored the performance of the Fund's service providers and provided the Fund with personnel (including Fund officers) and other resources that are necessary for the Fund's business management and operations, and considered the personnel and resources that Victory Capital proposed to provide with respect to such services. The Directors also considered that, as administrator, Amundi US was responsible for the administration of the Fund's business and other affairs and that, post-Transaction, Victory Capital would be responsible for the administration of the Fund's business and other affairs. The Directors considered that the fees Victory Capital would charge for administration services are higher than the fees that Amundi US received as reimbursement for services rendered, and considered Victory Capital's explanation of the reasons for the differences in administration fees charged by Victory Capital and Amundi US as well as the expense limitation arrangements proposed to be implemented for the Fund for at least three years following the completion of the Transaction.

The Directors considered that the terms and conditions of the New Investment Advisory Agreement were substantially similar to the terms and conditions of the Amundi US Investment Advisory Agreement, except for different execution dates, effective dates and termination dates. The Directors considered that the terms of the Interim Investment Advisory Agreement (including fees) also are substantially the same as the terms of the Amundi US Investment Advisory Agreement, that the Interim Investment Agreement allows Victory Capital to manage each Fund for up to 150 days following the closing of the Transaction, and that investment advisory fees payable under the Interim Investment Advisory Agreement will be held in escrow during the term of the Interim Investment Advisory Agreement.

The Directors received and considered information regarding the Victory Funds' key service providers, including custody, transfer agency and administration service providers, the fees charged by such service providers as compared to the fees charged by the Fund's current service providers, and Victory Capital's plans to propose the transition from certain of the Fund's current service providers to the Victory Funds' service providers following the consummation of the Transaction.

The Directors considered that Victory Capital had advised the Board that, notwithstanding the above, the Transaction was not expected to have a

------

[**Table of Contents**](#JOB_Amund_24b87121-7720-4859-9c42-d1ef94d3c34b_TOC)

material adverse impact on the nature, scope and overall quality of services provided to the Fund and its stockholders, including investment advisory, risk management, administrative, compliance, legal and other services, as a result of the Transaction. In that regard, the Directors considered the statements by representatives of Victory Capital that they did not foresee major changes in the day-to-day investment management operations of the Fund as a direct result of the Transaction, and also considered the risk management, legal and compliance services that Victory Capital would provide with respect to the Fund.

Based on these considerations, the Directors concluded that the nature, extent and quality of services that are proposed to be provided by Victory Capital to the Fund would be satisfactory and consistent with the terms of the Investment Advisory Agreement.

Performance of the Fund

In considering the Fund's performance, the Directors regularly reviewed and discussed throughout the year data prepared by Amundi US and information comparing the Fund's performance with the performance of its peer group of funds, as classified by Morningstar, Inc. (Morningstar), and with the performance of the Fund's benchmark index. The Directors also regularly considered the Fund's returns at market value relative to its peers, as well as the discount at which the Fund's shares may trade on the New York Stock Exchange compared to its net asset value per share. They also discussed the Fund's performance with Amundi US on a regular basis. The Directors' regular reviews and discussions factored into the Directors' deliberations concerning the approval of the New Investment Advisory Agreement.

In addition, the Board considered that the Fund's portfolio managers were expected to continue to act as portfolio managers of the Fund following the consummation of the Transaction as members of Pioneer Investments, a Victory Capital investment franchise. The Board also considered that no changes were proposed to the Fund's investment objective(s) or principal investment strategies in connection with the Transaction and the New Investment Advisory Agreement.

Advisory Fee and Expenses

The Directors noted that the advisory fee rate payable by the Fund was identical under the Amundi US Investment Advisory Agreement and the New Investment Advisory Agreement. The Directors considered information received in connection with the Directors' consideration of the renewal of the Amundi US Investment Advisory Agreement at in-person meetings held on September 17, 2024 showing the fees and expenses of the Fund in

[**Table of Contents**](#JOB_Amund_24b87121-7720-4859-9c42-d1ef94d3c34b_TOC)

comparison to the advisory fees and expense ratios of a peer group of funds selected on the basis of criteria determined by the Independent Directors for this purpose using data provided by Strategic Insight Mutual Fund Research and Consulting, LLC (Strategic Insight), an independent third party. The peer group comparisons referred to below are organized in quintiles. Each quintile represents one-fifth of the peer group. In all peer group comparisons referred to below, first quintile is most favorable to the Fund's shareowners.

The Directors considered that the Fund's advisory fee (based on managed assets) for the Fund's fiscal year ended March 31, 2024 was in the second quintile relative to the advisory fees paid by other funds in its Strategic Insight peer group for the comparable period. The Directors considered that the expense ratio (based on managed assets) of the Fund's common stock for the most recent fiscal year was in the first quintile (including investment-related expenses) and in the fourth quintile (excluding investment-related expenses), in each case relative to its Strategic Insight peer group for the comparable period. The Directors noted Amundi US's explanation of the reasons that the expense ratio of the Fund's common stock was in the fourth quintile (excluding investment-related expenses) relative to its Strategic Insight peer group.

The Directors also considered Victory Capital's contractual commitment under the expense limitation agreement to waive fees and/or reimburse expenses for at least three years after the closing of the Transaction, so that the Fund's total net annual operating expenses (excluding certain customary items) does not exceed the lower of (i) the total net annual operating expenses associated with investing in the Fund after application of expense limitation arrangements currently in effect for the Fund, if any, or (ii) the total net annual operating expenses of the Fund as of the end of the Fund's most recent fiscal year, at the time the Transaction closes. The Directors considered that the expense limitation agreement permits Victory Capital to recoup advisory fees waived and expenses reimbursed for up to two years after the fiscal year in which the waiver or reimbursement took place, subject to the lesser of any operating expense limitation in effect at the time of: (1) the original waiver or expense reimbursement; or (2) recoupment, after giving effect to the recoupment amount.

The Directors also considered that Victory Capital does not manage closed-end funds except for the Pioneer closed-end funds.

The Directors concluded that the advisory fee payable by the Fund to Victory Capital under the New Investment Advisory Agreement was reasonable in relation to the nature and quality of the services to be provided by Victory Capital.

Profitability

The Directors considered information provided by Victory Capital regarding the estimated profitability of Victory Capital with respect to the advisory services proposed to be provided by Victory Capital to the Fund, including the methodology used by Victory Capital in allocating certain of its costs to the management of the Fund. The Directors also considered Victory Capital's profit margins in connection with the overall operation of the Fund. The Board considered the investments Victory Capital expected to make to support and grow the Pioneer funds brand and the costs to integrate the Amundi US/Pioneer Funds business into Victory Capital. The Board also considered information regarding Victory Capital's profit margins with respect to the funds it currently manages. The Board considered Victory Capital's representation that the fully integrated Amundi US/Pioneer Funds business, including investments to support ongoing growth, was expected to have a positive impact on Victory Capital's overall financial profitability. The Directors considered Victory Capital's profit margins in comparison to the limited industry data available and noted that the profitability of any adviser was affected by numerous factors, including its organizational structure and method for allocating expenses. The Directors concluded that Victory Capital's estimated profitability with respect to the management of the Fund was not unreasonable.

Economies of Scale

The Directors considered the extent to which Victory Capital may realize economies of scale or other efficiencies in managing and supporting the Fund. Since the Fund is a closed-end fund that has not raised additional capital, the Directors concluded that economies of scale were not a relevant consideration in the renewal of the investment advisory agreement.

Other Benefits

The Directors considered the other benefits that Victory Capital may enjoy from its relationship with the Fund. The Directors considered the character and amount of fees to be paid by the Fund, other than under the New Investment Advisory Agreement, for services to be provided by Victory Capital and its affiliates. The Directors further considered the revenues and profitability of Victory Capital's businesses other than the Fund business. To the extent applicable, the Directors also considered the potential benefits to the Fund and to Victory Capital and its affiliates from the use of "soft" commission dollars generated by the Fund to pay for research and brokerage services.

[**Table of Contents**](#JOB_Amund_24b87121-7720-4859-9c42-d1ef94d3c34b_TOC)

The Directors noted that the completion of the Transaction would result in a long-term reciprocal distribution partnership between Amundi and Victory Capital, and that Victory Capital may benefit from Amundi's ability to market the services of Victory Capital globally, including in an increase of the overall scale of Victory Capital. The Directors considered that the Transaction, if completed, would significantly increase Victory Capital's assets under management and expand Victory Capital's investment capabilities. The Directors considered that this increased size and diversification could facilitate Victory Capital's continued investment in its business and products, which Victory Capital would be able to leverage across a broader base of assets. The Directors considered that Victory Capital and the Fund are expected to receive reciprocal intangible benefits from the relationship, including mutual brand recognition. The Directors concluded that any such benefits received by Victory Capital as a result of its relationship with the Fund were reasonable.

Conclusion

After consideration of the factors described above as well as other factors, the Directors, including the Independent Directors, concluded that the New Investment Advisory Agreement and the Interim Investment Advisory Agreement for the Fund, including the fees payable thereunder, were fair and reasonable and voted to approve the New Investment Advisory Agreement and the Interim Investment Advisory Agreement.

PIONEER FUNDS

APPROVAL OF AUDIT, AUDIT-RELATED, TAX AND OTHER SERVICES

PROVIDED BY THE INDEPENDENT AUDITOR

SECTION I - POLICY PURPOSE AND APPLICABILITY

The Pioneer Funds recognize the importance of maintaining the independence of their outside auditors. Maintaining independence is a shared responsibility involving Amundi Asset Management US, Inc., the audit committee and the independent auditors.

The Funds recognize that a Fund's independent auditors: 1) possess knowledge of the Funds, 2) are able to incorporate certain services into the scope of the audit, thereby avoiding redundant work, cost and disruption of Fund personnel and processes, and 3) have expertise that has value to the Funds. As a result, there are situations where it is desirable to use the Fund's independent auditors for services in addition to the annual audit and where the potential for conflicts of interests are minimal. Consequently, this policy, which is intended to comply with Rule 210.2-01(C)(7), sets forth guidelines and procedures to be followed by the Funds when retaining the independent audit firm to perform audit, audit-related tax and other services under those circumstances, while also maintaining independence.

Approval of a service in accordance with this policy for a Fund shall also constitute approval for any other Fund whose pre-approval is required pursuant to Rule 210.2-01(c)(7)(ii).

In addition to the procedures set forth in this policy, any non-audit services that may be provided consistently with Rule 210.2-01 may be approved by the Audit Committee itself and any pre-approval that may be waived in accordance with Rule 210.2-01(c)(7)(i)(C) is hereby waived.

Selection of a Fund's independent auditors and their compensation shall be determined by the Audit Committee and shall not be subject to this policy.

**Approval of Renewal of Investment Management Agreement with Amundi Asset Management US, Inc. and Approval of Interim Investment Advisory Agreement with Victory Capital Management Inc.** 

------

Effective April 1, 2025, Amundi Asset Management US, Inc. ("Amundi US"), the Fund's previous investment adviser, has been contributed to Victory Capital Holdings, Inc. ("Victory Capital Holdings"), the parent company of Victory Capital Management Inc. ("Victory Capital") (the "Transaction"). As a result of the Transaction, the Fund's investment advisory agreement with Amundi US (the "Amundi US Investment Advisory Agreement") terminated automatically on April 1, 2025. In connection with the Transaction, the Fund's Board of Directors (the "Board" or the "Directors") approved a new investment advisory agreement with Victory Capital (the "New Investment Advisory Agreement") at a Board meeting held on December 16, 2024, subject to approval by the Fund's stockholders. As of May 1, 2025, the Fund's stockholders had not approved the New Investment Advisory Agreement. At the December 16, 2024 Board meeting, the Board also approved an interim investment advisory agreement with Victory Capital (the "Interim Investment Advisory Agreement") to take effect upon the closing of the Transaction in the event that additional time was needed to solicit stockholder approval of the New Investment Advisory Agreement. The Board's considerations in approving the New Investment Advisory Agreement and the Interim Investment Advisory Agreement are discussed below.

#### Board Evaluation of the New Investment Advisory Agreement and Interim Investment Advisory Agreement
The Board evaluated the Transaction and the New Investment Advisory Agreement and Interim Investment Advisory Agreement for the Fund. At in-person meetings held on May 14-15, 2024, July 22-23, 2024, September 16-17, 2024, November 12-13, 2024, and December 16, 2024, the Board met to consider the Transaction, including the plan to contribute Amundi US to Victory Capital Holdings in exchange for Amundi Asset Management S.A.S. ("Amundi") becoming a significant shareholder of Victory Capital Holdings, and to establish a long-term reciprocal distribution partnership between Amundi and Victory Capital. The Board was advised that the Transaction, if completed, would constitute a change of control under the 1940 Act that would result in the termination of the Amundi US Investment Advisory Agreement.

At these meetings, which included meetings of the full Board and separate meetings of the Independent Directors, and at video conferences of the Independent Directors held on May 23, 2024, June 24, 2024, August 19, 2024, October 29, 2024 and December 9, 2024, the Board or the Independent Directors, as the case may be, considered, among other things, whether it would be in the best interests of the Fund and its stockholders to approve the New Investment Advisory Agreement. To assist the Board in its consideration of the New Investment Advisory Agreement and the anticipated impacts of the Transaction on the Fund and its stockholders, Victory Capital provided materials and information about Victory Capital, including its financial condition and asset management capabilities and organization, and Victory Capital and Amundi provided materials and information about the proposed Transaction between Victory Capital and Amundi.

To assist the Board in its consideration of the New Investment Advisory Agreement, Victory Capital provided extensive information to the Board regarding the Transaction and the investment advisory services to be provided by Victory Capital under the New Investment Advisory Agreement. Before and during the December 16, 2024 meeting, the Board sought additional information as it deemed necessary and appropriate. In connection with their consideration of the New Investment Advisory Agreement, the Independent Directors worked with their independent legal counsel to prepare requests for additional information that were submitted to Victory Capital and Amundi US. The Board's requests for information sought information relevant to the Board's consideration of the New Investment Advisory Agreement and other anticipated impacts of the Transaction on the Fund and its stockholders. In addition, the Board formed a Transaction Sub-Committee, comprised solely of Independent Directors, to assist the Board in its consideration of the New Investment Advisory Agreement and the Transaction. The Board and the Transaction Sub- Committee met with senior management representatives of Victory Capital and Amundi US on numerous occasions to discuss various aspects of the Transaction, to review information provided to assist the Board in its consideration of the New Investment Advisory Agreement and the

------

Transaction, and to make supplemental due diligence requests for additional information from Victory Capital and Amundi US with respect to the New Investment Advisory Agreement and the Transaction. Victory Capital and Amundi US provided documents and information in response to the requests from the Board and the Transaction Sub-Committee, as well as made presentations to, and responded to questions from, the Board and the Transaction Sub-Committee at various meetings.

Prior to voting on the New Investment Advisory Agreement, the Independent Directors reviewed the Transaction and the New Investment Advisory Agreement with representatives of Amundi US and Victory Capital, counsel to the Fund and counsel to the Independent Directors. The Independent Directors also reviewed the Transaction and the New Investment Advisory Agreement with their counsel in private sessions at which no representatives of Amundi US, Victory Capital or counsel to the Fund were present.

The Board's evaluation of the New Investment Advisory Agreement reflected the information provided specifically in connection with its review of the New Investment Advisory Agreement, as well as, where relevant, information that was previously furnished to the Board in connection with the renewal of the Amundi US Investment Advisory Agreement at inperson meetings held on September 17, 2024 and at other Board meetings throughout the prior year.

Among other things, the Directors considered:

(i) that, in the Transaction, Amundi US would be contributed to Victory Capital in exchange for shares of Victory Capital Holdings issued to Amundi without Amundi becoming a controlling stockholder of Victory Capital Holdings, and that Victory Capital and Amundi would establish a longterm reciprocal distribution partnership;

(ii) representations by Victory Capital regarding the reputation, experience, financial strength and resources of Victory Capital and its investment franchises;

(iii) that Victory Capital has informed the Board that the Transaction was not expected to have a material adverse impact on the nature, scope and overall quality of services provided to the Fund and its stockholders, including investment management, risk management, administrative, compliance, legal and other services;

(iv) that Victory Capital informed the Board that the portfolio managers of the Fund were expected to continue to act as portfolio managers of the Fund following the consummation of the Transaction as members of Pioneer Investments, a planned Victory Capital investment franchise, managing the Fund using the same investment approach under which the Fund was previously managed, and the Board considered the historical investment performance record of the Fund under such investment approach;

(v) the non-investment resources, infrastructure and personnel of Victory Capital that would be involved in Victory Capital's services to the Fund, including Victory Capital's legal and operational structure, risk management, administrative, legal, compliance and cybersecurity functions;

(vi) that the Fund's contractual advisory fee rate would remain the same and would not increase by virtue of the New Investment Advisory Agreement;

(vii) the terms and conditions of the New Investment Advisory Agreement, including that the New Investment Advisory Agreement was substantially identical to the Amundi US Investment Advisory Agreement;

(viii) the terms of the Interim Investment Advisory Agreement (including fees) also are substantially the same as the terms of the Amundi US Investment Advisory Agreement, that the Interim Investment Agreement allows Victory Capital to manage each Fund for up to 150 days following the closing of the Transaction, and that investment advisory fees payable under the Interim Investment Advisory Agreement will be held in escrow during the term of the Interim Investment Advisory Agreement;

(ix) that the Directors had recently approved the continuance of the Amundi US Investment Advisory Agreement with Amundi US at an inperson meeting held on September 17, 2024 and, in connection with the Directors' review of the Amundi US Investment Advisory Agreement, received and considered full comparative fee and expense data;

------

(x) Victory Capital's plans to propose to transition from certain of the Fund's current service providers, including fund administration, to the Victory Funds' service providers following the consummation of the Transaction

(xi) that Victory Capital had agreed with the Board that, for at least three years after the Transaction closes, Victory Capital would waive fees and/or reimburse expenses so that the Fund's total net annual operating expenses (excluding certain customary items) does not exceed the lower of (i) the total net annual operating expenses associated with investing in the Fund after application of expense limitation arrangements currently in effect for the Fund, if any, or (ii) the total net annual operating expenses of the Fund as of the end of the Fund's most recent fiscal year at the time of the Transaction close, and that the contractual expense limitation agreement permits Victory Capital to recoup advisory fees waived and expenses reimbursed for up to two years after the fiscal year in which the waiver or reimbursement took place, subject to the lesser of any operating expense limitation in effect at the time of: (1) the original waiver or expense reimbursement; or (2) recoupment, after giving effect to the recoupment amount;

(xii) that Victory Capital did not expect to propose any changes to the investment objective(s) of the Fund or any changes to the principal investment strategies of the Fund as a result of the Transaction;

(xiii) that Victory Capital had acquired and integrated several investment management companies;

(xiv) the potential benefits to the stockholders of the Fund, including continuity of portfolio management and operating efficiencies due to the greater scale of Victory Capital that may be achieved from the Transaction;

(xv) that Victory Capital and Amundi would each derive benefits from the Transaction and that, as a result, they had a financial interest in the matters that were being considered;

(xvi) that Victory Capital and Amundi had agreed to conduct, and use reasonable best efforts to cause their affiliates to conduct, their respective businesses in compliance with Section 15(f) of the 1940 Act so as not to impose an "unfair burden" on the Fund; and

(xvii) that the Fund would not bear the costs of obtaining stockholder approval of the New Investment Advisory Agreement, including proxy solicitation costs, legal fees and the costs of printing and mailing the proxy statement, regardless of whether the Transaction is consummated. Certain of these considerations are discussed in more detail below.

The Directors also requested, obtained and considered the following information in connection with their evaluation of the Transaction and the New Investment Advisory Agreement for the Fund: (i) memoranda provided by Fund counsel that summarized the legal standards and other considerations that are relevant to the Directors in their deliberations regarding the New Investment Advisory Agreement; and (ii) the Fund's advisory fees and total expense ratios, the financial statements of Victory Capital, a profitability analysis provided by Victory Capital, and an analysis from Victory Capital as to possible economies of scale. The Directors further considered, materials provided in connection with their review of the Amundi US Investment Advisory Agreement, including, for the Fund, information regarding the qualifications of the investment management teams for the Fund, as well as the level of investment by the Fund's portfolio managers in the Fund. In addition, the Directors considered the information provided at regularly scheduled meetings throughout the year regarding the Fund's performance and risk attributes, including through meetings with investment management personnel, and took into account other information related to the Fund provided to the Directors at regularly scheduled meetings.

At the December 16, 2024, meeting, based on their evaluation of the information provided by Victory Capital and Amundi US, the Directors including the Independent Directors voting separately, approved the New Investment Advisory Agreement and the Interim Investment Advisory Agreement for the Fund. In considering the New Investment Advisory Agreement for the Fund, the Directors considered various factors that they determined were relevant, including the factors described below. The Directors did not identify any single factor as the controlling factor in their determinations. The Directors considered the same factors with respect to the Interim Investment Advisory Agreement for the Fund.

------

#### Nature, Extent and Quality of Services.
The Directors considered the nature, extent and quality of the services that had been provided by Amundi US to the Fund and that were expected to be provided by Victory Capital to the Fund following the consummation of the Transaction, taking into account the investment objective(s) and principal investment strategies of the Fund.

The Board considered information provided by Victory Capital regarding its business and operating structure, scale of operations, leadership and reputation. The Board also considered the capabilities, resources, and personnel of Victory Capital, in order to determine whether Victory Capital was capable of providing the same level of investment management services provided to the Fund by Amundi US. The Board received information regarding Victory Capital's plans to integrate Amundi US investment personnel into Victory Capital as members of Pioneer Investments, a Victory Capital investment franchise. The Board noted that it had considered the qualifications of the portfolio managers at Amundi US at its September 17, 2024 Meeting.

The Directors considered Victory Capital's representation that there would be no change to the investment approach under which the Fund would be managed under the New Investment Advisory Agreement.

The Board considered the non-investment resources, infrastructure and personnel of Victory Capital that would be involved in Victory Capital's services to the Fund, including Victory Capital's compliance, risk management, cybersecurity and legal resources and personnel. The Board also reviewed information provided by Victory Capital related to its business, legal, and regulatory affairs, including information regarding the resources available to Victory Capital to provide the services specified under the New Investment Advisory Agreement. The Board also considered Victory Capital's financial condition, and noted that Victory Capital was expected to be able to provide a high level of service to the Fund and continuously invest and re-invest in its investment management business.

The Directors considered that Amundi US previously supervised and monitored the performance of the Fund's service providers and provided the Fund with personnel (including Fund officers) and other resources that are necessary for the Fund's business management and operations, and considered the personnel and resources that Victory Capital proposed to provide with respect to such services. The Directors also considered that, as administrator, Amundi US was responsible for the administration of the Fund's business and other affairs and that, post-Transaction, Victory Capital would be responsible for the administration of the Fund's business and other affairs. The Directors considered that the fees Victory Capital would charge for administration services are higher than the fees that Amundi US received as reimbursement for services rendered, and considered Victory Capital's explanation of the reasons for the differences in administration fees charged by Victory Capital and Amundi US as well as the expense limitation arrangements proposed to be implemented for the Fund for at least three years following the completion of the Transaction.

The Directors considered that the terms and conditions of the New Investment Advisory Agreement were substantially similar to the terms and conditions of the Amundi US Investment Advisory Agreement, except for different execution dates, effective dates and termination dates. The Directors considered that the terms of the Interim Investment Advisory Agreement (including fees) also are substantially the same as the terms of the Amundi US Investment Advisory Agreement, that the Interim Investment Agreement allows Victory Capital to manage each Fund for up to 150 days following the closing of the Transaction, and that investment advisory fees payable under the Interim Investment Advisory Agreement will be held in escrow during the term of the Interim Investment Advisory Agreement.

The Directors received and considered information regarding the Victory Funds' key service providers, including custody, transfer agency and administration service providers, the fees charged by such service providers as compared to the fees charged by the Fund's current service providers, and Victory Capital's plans to propose the transition from certain of the Fund's current service providers to the Victory Funds' service providers following the consummation of the Transaction.

The Directors considered that Victory Capital had advised the Board that, notwithstanding the above, the Transaction was not expected to have a material adverse impact on the nature, scope and overall quality of services provided to the Fund and its stockholders, including investment advisory, risk management, administrative, compliance, legal and other services, as a

------

result of the Transaction. In that regard, the Directors considered the statements by representatives of Victory Capital that they did not foresee major changes in the day-to-day investment management operations of the Fund as a direct result of the Transaction, and also considered the risk management, legal and compliance services that Victory Capital would provide with respect to the Fund.

Based on these considerations, the Directors concluded that the nature, extent and quality of services that are proposed to be provided by Victory Capital to the Fund would be satisfactory and consistent with the terms of the Investment Advisory Agreement.

#### Performance of the Fund
In considering the Fund's performance, the Directors regularly reviewed and discussed throughout the year data prepared by Amundi US and information comparing the Fund's performance with the performance of its peer group of funds, as classified by Morningstar, Inc. (Morningstar), and with the performance of the Fund's benchmark index. The Directors also regularly considered the Fund's returns at market value relative to its peers, as well as the discount at which the Fund's shares may trade on the New York Stock Exchange compared to its net asset value per share. They also discussed the Fund's performance with Amundi US on a regular basis. The Directors' regular reviews and discussions factored into the Directors' deliberations concerning the approval of the New Investment Advisory Agreement.

In addition, the Board considered that the Fund's portfolio managers were expected to continue to act as portfolio managers of the Fund following the consummation of the Transaction as members of Pioneer Investments, a Victory Capital investment franchise. The Board also considered that no changes were proposed to the Fund's investment objective(s) or principal investment strategies in connection with the Transaction and the New Investment Advisory Agreement.

#### Advisory Fee and Expenses
The Directors noted that the advisory fee rate payable by the Fund was identical under the Amundi US Investment Advisory Agreement and the New Investment Advisory Agreement. The Directors considered information received in connection with the Directors' consideration of the renewal of the Amundi US Investment Advisory Agreement at in-person meetings held on September 17, 2024 showing the fees and expenses of the Fund in comparison to the advisory fees and expense ratios of a peer group of funds selected on the basis of criteria determined by the Independent Directors for this purpose using data provided by Strategic Insight Mutual Fund Research and Consulting, LLC (Strategic Insight), an independent third party. The peer group comparisons referred to below are organized in quintiles. Each quintile represents one-fifth of the peer group. In all peer group comparisons referred to below, first quintile is most favorable to the Fund's shareowners.

The Directors considered that the Fund's advisory fee (based on managed assets) for the Fund's fiscal year ended March 31, 2024 was in the second quintile relative to the advisory fees paid by other funds in its Strategic Insight peer group for the comparable period. The Directors considered that the expense ratio (based on managed assets) of the Fund's common stock for the most recent fiscal year was in the first quintile (including investment-related expenses) and in the fourth quintile (excluding investment-related expenses), in each case relative to its Strategic Insight peer group for the comparable period. The Directors noted Amundi US's explanation of the reasons that the expense ratio of the Fund's common stock was in the fourth quintile (excluding investment-related expenses) relative to its Strategic Insight peer group.

The Directors also considered Victory Capital's contractual commitment under the expense limitation agreement to waive fees and/or reimburse expenses for at least three years after the closing of the Transaction, so that the Fund's total net annual operating expenses (excluding certain customary items) does not exceed the lower of (i) the total net annual operating expenses associated with investing in the Fund after application of expense limitation arrangements currently in effect for the Fund, if any, or (ii) the total net annual operating expenses of the Fund as of the end of the Fund's most recent fiscal year, at the time the Transaction closes. The Directors considered that the expense limitation agreement permits Victory Capital to recoup advisory fees waived and expenses reimbursed for up to two years after the fiscal year in which the waiver or reimbursement took

------

place, subject to the lesser of any operating expense limitation in effect at the time of: (1) the original waiver or expense reimbursement; or (2) recoupment, after giving effect to the recoupment amount. The Directors also considered that Victory Capital does not manage closedend funds except for the Pioneer closed-end funds. The Directors concluded that the advisory fee payable by the Fund to Victory Capital under the New Investment Advisory Agreement was reasonable in relation to the nature and quality of the services to be provided by Victory Capital.

#### Profitability
The Directors considered information provided by Victory Capital regarding the estimated profitability of Victory Capital with respect to the advisory services proposed to be provided by Victory Capital to the Fund, including the methodology used by Victory Capital in allocating certain of its costs to the management of the Fund. The Directors also considered Victory Capital's profit margins in connection with the overall operation of the Fund. The Board considered the investments Victory Capital expected to make to support and grow the Pioneer funds brand and the costs to integrate the Amundi US/Pioneer Funds business into Victory Capital. The Board also considered information regarding Victory Capital's profit margins with respect to the funds it currently manages. The Board considered Victory Capital's representation that the fully integrated Amundi US/Pioneer Funds business, including investments to support ongoing growth, was expected to have a positive impact on Victory Capital's overall financial profitability. The Directors considered Victory Capital's profit margins in comparison to the limited industry data available and noted that the profitability of any adviser was affected by numerous factors, including its organizational structure and method for allocating expenses. The Directors concluded that Victory Capital's estimated profitability with respect to the management of the Fund was not unreasonable.

#### Economies of Scale
The Directors considered the extent to which Victory Capital may realize economies of scale or other efficiencies in managing and supporting the Fund. Since the Fund is a closed-end fund that has not raised additional capital, the Directors concluded that economies of scale were not a relevant consideration in the renewal of the investment advisory agreement.

#### Other Benefits
The Directors considered the other benefits that Victory Capital may enjoy from its relationship with the Fund. The Directors considered the character and amount of fees to be paid by the Fund, other than under the New Investment Advisory Agreement, for services to be provided by Victory Capital and its affiliates. The Directors further considered the revenues and profitability of Victory Capital's businesses other than the Fund business. To the extent applicable, the Directors also considered the potential benefits to the Fund and to Victory Capital and its affiliates from the use of "soft" commission dollars generated by the Fund to pay for research and brokerage services.

The Directors noted that the completion of the Transaction would result in a long-term reciprocal distribution partnership between Amundi and Victory Capital, and that Victory Capital may benefit from Amundi's ability to market the services of Victory Capital globally, including in an increase of the overall scale of Victory Capital. The Directors considered that the Transaction, if completed, would significantly increase Victory Capital's assets under management and expand Victory Capital's investment capabilities. The Directors considered that this increased size and diversification could facilitate Victory Capital's continued investment in its business and products, which Victory Capital would be able to leverage across a broader base of assets. The Directors considered that Victory Capital and the Fund are expected to receive reciprocal intangible benefits from the relationship, including mutual brand recognition. The Directors concluded that any such benefits received by Victory Capital as a result of its relationship with the Fund were reasonable.

#### Conclusion
After consideration of the factors described above as well as other factors, the Directors, including the Independent Directors, concluded that the New Investment Advisory Agreement and the Interim Investment Advisory Agreement for the Fund, including the fees payable thereunder, were fair and reasonable and voted to approve the New Investment Advisory Agreement and the Interim Investment Advisory Agreement.

ITEM 12. DISCLOSURE OF PROXY VOTING POLICIES AND PROCEDURES FOR CLOSED-END MANAGEMENT INVESTMENT COMPANIES. (Unaudited)

A closed-end management investment company that is filing an annual report on this Form N-CSR must, unless it invests exclusively in non-voting securities, describe the policies and procedures that it uses to determine how to vote proxies relating to portfolio securities, including the procedures that the company uses when a vote presents a conflict between the interests of its shareholders, on the one hand, and those of the company's investment adviser; principal underwriter; or any affiliated person (as defined in Section 2(a)(3) of the Investment Company Act of 1940 (15 U.S.C. 80a-2(a)(3)) and the rules thereunder) of the company, its investment adviser, or its principal underwriter, on the other. Include any policies and procedures of the company's investment adviser, or any other third party, that the company uses, or that are used on the company's behalf, to determine how to vote proxies relating to portfolio securities.

------

![LOGO](g940378g0704023647578.jpg)

#### H-12 PROXY VOTING

#### BACKGROUND AND RISKS
Voting rights associated with security ownership are closely related to the discretionary asset management services VCM provides to its clients. Therefore, VCM should be capable of accepting and exercising voting authority on behalf of clients with the same standard of care, skill, prudence, and diligence it is subject to when exercising its investment authority on behalf of clients. Further, in order to exercise voting authority on behalf of clients, VCM must comply with Rule 206(4)-6 of the Advisers Act (the "proxy rule") and Rule 14Ad-1 of the Securities and Exchange Act of 1934 (the "proxy reporting rule"). The proxy rule requires VCM to adopt and implement written policies and procedures designed to ensure it votes securities in the best interest of clients including managing material conflicts of interest between VCM and its clients, to disclose to clients a summary of its proxy voting policies and procedures, how they may obtain a copy of these procedures, and information about how VCM voted their securities. The proxy reporting rule requires certain investment managers to report their proxy voting record annually on Form N-PX with respect to certain votes on executive compensation.

Inability to accept and exercise voting authority on behalf of clients or failure to comply with the proxy rule or proxy reporting rule could result in violations of securities law, breach of fiduciary duty, client harm, or damage to VCM's reputation.

#### POLICY
VCM will establish policies and procedures and retain resources necessary to ensure it is capable of exercising voting authority on behalf of clients according to the same standard of care with which it exercises investment authority. Because VCM will exercise voting authority, it will comply with the proxy rule and the proxy reporting rule and must vote securities in the best interest of clients.

For purposes of this policy, voting in the best interest of clients means using complete and accurate information to vote with the objective of increasing the long-term economic value of client assets. Similar to investment decision making, voting decisions are qualitative in nature and VCM will consider a variety of factors to arrive at vote decisions. Further a voting decision in the same security may be different between clients for the same reasons VCM clients are invested in different securities. For example, client agreements, investment strategies, or specific investment franchise views on ballot proposals may cause the same security to be voted in a different manner across VCM's client base.

1 \| Page

------

![LOGO](g940378g0704023647578.jpg)

VCM will vote all securities over which it has authority, provided the client has voting rights and there is sufficient time and information available to make informed decisions. VCM will take reasonable steps to obtain appropriate and timely information.

In situations where voting may impact the ability to trade a security (e.g., shareblocking), VCM will not vote unless it determines that voting is in a client's best interest.

For a copy of the guidelines (as defined below) please visit VCM's website at <u>https://investor.vcm.com/policies</u>. To obtain information on specific proxies voted by VCM, clients may contact their VCM client manager or email an inquiry to <u>client_service_team@vcm.com</u>.

VCM will create, maintain, and retain appropriate records related to voting client securities.

#### LIST OF REQUIRED CONTROLS
• Proxy Voting Committee (the "committee")

• Client Investment Management Agreements ("IMAs")

• Third-party proxy firm ("proxy firm")

• M-19 Vendor Due Diligence and Oversight ("vendor oversight policy")

• Proxy voting guidelines

• Annual committee guideline review

• Form ADV, Part 2A

• M-13 Record Retention and Destruction, Appendix A ("recordkeeping requirements")

#### CONTROL IMPLEMENTATION PROCEDURES
• The committee will consist of members with experience related to the functional areas applicable to voting client securities including responsible investing, investment management, operations, and compliance. The committee is responsible for exercising VCM's fiduciary responsibilities related to voting client securities including voting in the best interests of clients and identifying and managing conflicts of interest. The committee will be active, keep a charter, and maintain records that demonstrate adequate execution of its responsibilities.

------

![LOGO](g940378g0704023647578.jpg)

• When a client enters into an advisory relationship with VCM, proxy voting roles and responsibilities between the client and VCM will be fully disclosed. Responsibilities delegated to VCM will be communicated to the committee and the committee will be responsible for implementing voting requirements in accordance with each IMA.

• In order to support its fiduciary duty related to voting client securities and comply with the proxy rule and proxy reporting rule, VCM will retain, and the committee will oversee a third-party proxy advisory firm ("proxy firm") to provide both administrative and advisory services related to voting client securities. In relation to the proxy reporting rule, the proxy firm will provide draft filings in the appropriate format. The Business Owner of this policy is responsible for ensuring the accuracy of the filing. The Compliance Owner is responsible for ensuring the report is filed in a timely manner and complies with the proxy reporting rule. Selection and ongoing oversight of the proxy firm will be conducted in accordance with the vendor oversight policy. The Sponsor, as defined in the vendor oversight policy, must be a member of the committee. Currently, VCM retains Institutional Shareholder Services Inc. as its proxy firm.

• The committee will adopt written proxy voting guidelines authored by the proxy firm ("guidelines"). These guidelines can be used as standing instructions on how the proxy firm must vote ballots provided that the committee must:

• Have the ability to customize the guidelines.

• Retain the ability to override the guidelines on individual ballot proposals at the client level.

• Review the guidelines at least annually, implement customizations based on this review, and submit a written memo to the compliance committee documenting the results of the annual review that includes the name of the proxy firm, links to the specific guidelines adopted, and a description of customizations made.

• Make the memo available to clients upon request.

------

![LOGO](g940378g0704023647578.jpg)

• The purpose of the guidelines is 1) to benefit from the specialized expertise related to voting securities provided by the proxy firm and to provide an independent source to resolve conflicts of interest identified between VCM and its clients. For the first purpose, the committee will take into account the guidelines but will have ultimate responsibility for voting decisions. The committee will, in its discretion, rely on additional sources such as portfolio manager input to ensure the voting decisions it makes are in the best interest of specific clients. If the guidelines are silent on any pending ballot proposal, the committee will exercise its voting responsibility with due care and document the rationale for the vote decision. For the second purpose, if the committee identifies a conflict of interest between VCM and clients, the committee must vote in accordance with the guidelines unless the rationale for deviating from guidelines has unanimous consent from the committee and is put in writing, including an analysis of how the conflict of interest is eliminated, mitigated, or disclosed.

• The proxy firm will provide technology-based platform that provides operational controls over voting securities that include, at minimum, ballot reconciliation, casting complete ballots in a timely manner and in accordance with adopted written guidelines, ability to adjust or override a vote based on committee input, and reporting capabilities that support compliance with the proxy reporting rule and VCM's need to oversee the proxy firm and report internally and externally. The committee is responsible for ensuring these controls are operating as intended though must, at minimum, develop reporting designed to ensure all eligible client accounts are properly set up and configured on the proxy firm's platform and that the proxy firm is voting securities in accordance with the guidelines and this policy. Such reports should be reviewed by the committee at regular intervals and any exceptions should be referred to the LCR department.

• The disclosures required under the proxy rule will be contained in VCM's Form ADV, Part 2A and will be delivered to clients at the time and frequency required by regulation.

• The committee will be familiar with the recordkeeping requirements related to voting client securities and will maintain records and ensure the proxy firm maintains records for the required periods.

#### Potential conflicts of interest
When a portfolio manager is responsible for the management of more than one account, the potential arises for the portfolio manager to favor one account over another. The principal types of potential conflicts of interest that may arise are discussed below. For the reasons outlined below, Amundi US does not believe that any material conflicts are likely to arise out of a portfolio manager's responsibility for the management of the fund as well as one or more other accounts. Although Amundi US has adopted procedures that it believes are reasonably designed to detect and prevent violations of the federal securities laws and to mitigate the potential for conflicts of interest to affect its portfolio management decisions, there can be no assurance that all conflicts will be identified or that all procedures will be effective in mitigating the potential for such risks. Generally, the risks of such conflicts of interest are increased to the extent that a portfolio manager has a financial incentive to favor one account over another. Amundi US has structured its compensation arrangements in a manner that is intended to limit such potential for conflicts of interest. See "Compensation of Portfolio Managers" below.

• A portfolio manager could favor one account over another in allocating new investment opportunities that have limited supply, such as initial public offerings and private placements. If, for example, an initial public offering that was expected to appreciate in value significantly shortly after the offering was allocated to a single account, that account may be expected to have better investment performance than other accounts that did not receive an allocation of the initial public offering. Generally, investments for which there is limited availability are allocated based upon a range of factors including available cash and consistency with the accounts' investment objectives and policies. This allocation methodology necessarily involves some subjective elements but is intended over time to treat each client in an equitable and fair manner. Generally, the investment opportunity is allocated among participating accounts on a pro rata basis. Although Amundi US believes that its practices are reasonably designed to treat each client in an equitable and fair manner, there may be instances where a fund may not participate, or may participate to a lesser degree than other clients, in the allocation of an investment opportunity.

------

• A portfolio manager could favor one account over another in the order in which trades for the accounts are placed. If a portfolio manager determines to purchase a security for more than one account in an aggregate amount that may influence the market price of the security, accounts that purchased or sold the security first may receive a more favorable price than accounts that made subsequent transactions. The less liquid the market for the security or the greater the percentage that the proposed aggregate purchases or sales represent of average daily trading volume, the greater the potential for accounts that make subsequent purchases or sales to receive a less favorable price. When a portfolio manager intends to trade the same security on the same day for more than one account, the trades typically are "bunched," which means that the trades for the individual accounts are aggregated and each account receives the same price. There are some types of accounts as to which bunching may not be possible for contractual reasons (such as directed brokerage arrangements). Circumstances may also arise where the trader believes that bunching the orders may not result in the best possible price. Where those accounts or circumstances are involved, Amundi US will place the order in a manner intended to result in as favorable a price as possible for such client.

• A portfolio manager could favor an account if the portfolio manager's compensation is tied to the performance of that account to a greater degree than other accounts managed by the portfolio manager. If, for example, the portfolio manager receives a bonus based upon the performance of certain accounts relative to a benchmark while other accounts are disregarded for this purpose, the portfolio manager will have a financial incentive to seek to have the accounts that determine the portfolio manager's bonus achieve the best possible performance to the possible detriment of other accounts. Similarly, if Amundi US receives a performance-based advisory fee, the portfolio manager may favor that account, whether or not the performance of that account directly determines the portfolio manager's compensation.

• A portfolio manager could favor an account if the portfolio manager has a beneficial interest in the account, in order to benefit a large client or to compensate a client that had poor returns. For example, if the portfolio manager held an interest in an investment partnership that was one of the accounts managed by the portfolio manager, the portfolio manager would have an economic incentive to favor the account in which the portfolio manager held an interest.

• If the different accounts have materially and potentially conflicting investment objectives or strategies, a conflict of interest could arise. For example, if a portfolio manager purchases a security for one account and sells the same security for another account, such trading pattern may disadvantage either the account that is long or short. In making portfolio manager assignments, Amundi US seeks to avoid such potentially conflicting situations. However, where a portfolio manager is responsible for accounts with differing investment objectives and policies, it is possible that the portfolio manager will conclude that it is in the best interest of one account to sell a portfolio security while another account continues to hold or increase the holding in such security.

#### Compensation of portfolio managers
Amundi US has adopted a system of compensation for portfolio managers that seeks to align the financial interests of the portfolio managers with those of shareholders of the accounts (including Pioneer funds) the portfolio managers manage, as well as with the financial performance of Amundi US. The compensation program for all Amundi US portfolio managers includes a base salary (determined by the rank and tenure of the employee) and an annual bonus program, as well as customary benefits that are offered generally to all full-time employees. Base compensation is fixed and normally reevaluated on an annual basis. Amundi US seeks to set base compensation at market rates, taking into account the experience and responsibilities of the portfolio manager. The bonus plan is intended to provide a competitive level of annual bonus compensation that is tied to the portfolio manager achieving superior investment performance and align

------

the interests of the investment professional with those of shareholders, as well as with the financial performance of Amundi US. Any bonus under the plan is completely discretionary, with a maximum annual bonus that may be in excess of base salary. The annual bonus is based upon a combination of the following factors:

• **Quantitative investment performance.** The quantitative investment performance calculation is based on pre-tax investment performance of all of the accounts managed by the portfolio manager (which includes the fund and any other accounts managed by the portfolio manager) over a one-year period (20% weighting) and four-year period (80% weighting), measured for periods ending on December 31. The accounts, which include the fund, are ranked against a group of mutual funds with similar investment objectives and investment focus (60%) and a securities market index measuring the performance of the same type of securities in which the accounts invest (40%), which, in the case of the fund, is the Bloomberg Municipal Bond Index and the Bloomberg U.S. Municipal High Yield Bond Index. As a result of these two benchmarks, the performance of the portfolio manager for compensation purposes is measured against the criteria that are relevant to the portfolio manager's competitive universe.

• **Qualitative performance.** The qualitative performance component with respect to all of the accounts managed by the portfolio manager includes objectives, such as effectiveness in the areas of teamwork, leadership, communications and marketing, that are mutually established and evaluated by each portfolio manager and management.

• **Amundi US results and business line results.** Amundi US's financial performance, as well as the investment performance of its investment management group, affect a portfolio manager's actual bonus by a leverage factor of plus or minus (+/–) a predetermined percentage.

The quantitative and qualitative performance components comprise 80% and 20%, respectively, of the overall bonus calculation (on a pre-adjustment basis). A portion of the annual bonus is deferred for a specified period and may be invested in one or more Pioneer funds.

Certain portfolio managers participate in other programs designed to reward and retain key contributors. Portfolio managers also may participate in a deferred compensation program, whereby deferred amounts are invested in one or more Pioneer funds or collective investment trusts or other unregistered funds with similar investment objectives, strategies and policies.

**CODE OF CONDUCT** 

**FOR PRINCIPAL EXECUTIVE OFFICER AND PRINCIPAL FINANCIAL OFFICER** 

**I.** **Covered Officers/Purpose of the Code** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**A.** This Code of Conduct (the "Code") applies to the Principal Executive Officer and Principal Financial Officer of the Funds, and the "Covered Officers", each of whom is set forth in Exhibit A, for the purpose of promoting:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. Honest and ethical conduct, including the ethical handling of actual or apparent conflicts of interest between
personal and professional relationships;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. Full, fair, accurate, timely and understandable disclosure in reports and documents that a registrant files
with, or submits to, the Securities and Exchange Commission ("SEC") and in other public communications made by the Trusts;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. Compliance with applicable laws and governmental rules and regulations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. The prompt internal reporting of violations of the Code to an appropriate person or persons identified in the
Code; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5. Accountability for adherence to the Code.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**B.** Each Covered Officer should adhere to a high standard of business ethics and should be sensitive to situations that may give rise to actual as well as apparent conflicts of interest.

------

**II.** **Covered Officers Should Handle Ethically Any Actual or Apparent Conflicts of Interest** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**A. Overview.** A "conflict of interest" occurs when a Covered Officer's private interest interferes with the interests of, or his or her service to, the Trusts. For example, a conflict of interest would arise if a Covered Officer, or a member of his family, receives improper personal benefits as a result of his or her position with the Trusts.

Certain conflicts of interest that could arise out of the relationships between Covered Officers and the Trusts already are subject to conflict of interest provisions in the Investment Company Act of 1940 ("Investment Company Act") and the Investment Advisers Act of 1940 ("Investment Advisers Act"). For example, Covered Officers may not individually engage in certain transactions (such as the purchase or sale of securities or other property) with the Trusts because of their status as "affiliated persons" of the Trusts. The Trusts' and their investment adviser's compliance programs and procedures are designed to prevent, or identify and correct, violations of these provisions. This Code does not, and is not intended to, repeat or replace these programs and procedures, and such conflicts fall outside of the parameters of this Code.

Although typically not presenting an opportunity for improper personal benefit, conflicts may arise or result from the contractual relationship between the Trusts and the investment adviser and the administrator, whose officers or employees also serve as Covered Officers. As a result, this Code recognizes that the Covered Officers will, in the normal course of their duties (whether formally for the Trusts or for the adviser or the administrator, or for both), be involved in establishing policies and implementing decisions that will have different effects on the adviser, the administrator and the Trusts. The participation of the Covered Officers in such activities is inherent in the contractual relationship between the adviser, the administrator and the Trusts and is consistent with the performance by the Covered Officers of their duties as officers of the Trusts. Thus, if performed in conformity with the provisions of the Investment Company Act and the Investment Advisers Act, such activities will be deemed to have been handled ethically. In addition, it is recognized by each Trust's Board of Trustees (the "Board") that the Covered Officers may also be officers or employees of one or more other investment companies covered by this or other codes.

Other conflicts of interest are covered by the Code, even if such conflicts of interest are not subject to provisions in the Investment Company Act or the Investment Advisers Act. Section C describes the types of conflicts of interest that are covered under this Code, but Covered Officers should keep in mind that these examples are not exhaustive. The overarching principle is that the personal interest of a Covered Officer should not be placed improperly before the interest of the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**B. Obligations of Covered Officers.** Each Covered Officer must:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. Not use his personal influence or personal relationships improperly to influence investment decisions or
financial reporting by the Trusts whereby the Covered Officer would benefit personally to the detriment of the Trusts;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. Not cause the Trusts to take action, or fail to take action, for the individual personal benefit of the Covered
Officer rather than the benefit of the Trusts;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. Report at least annually outside business affiliations or other relationships (*e.g.,* officer, director,
governor, trustee, part-time employment) other than his or her relationship to the Trusts, the investment adviser and the administrator.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**C. Conflicts of interest.** When a Covered Person becomes aware of a situation that could involve a conflict of interest, or that could reasonably be considered an appearance of a conflict of interest, the Covered Person should disclose this matter to the Chief Compliance Officer. For purposes of this Code, the Chief Compliance Officer shall be the Chief Compliance Officer of Victory Capital Management Inc. ("VCM"). Examples of these include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. Service as a director on the board of any public or private company; The receipt, as an officer of the Trusts,
of any gift in excess of $100;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. The receipt of any entertainment from any company with which the Trusts have current or prospective business
dealings, unless such entertainment is business-related, reasonable in cost, appropriate as to time and place, and not so frequent as to raise any question of impropriety;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. Any ownership interest in, or any consulting or employment relationship with, any of the Trusts' service
providers, other than their investment adviser, principal underwriter, administrator or any affiliated person thereof;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. A direct or indirect financial interest in commissions, transaction charges or spreads paid by the Trusts for
effecting portfolio transactions or for selling or redeeming shares other than an interest arising from the Covered Officer's employment, such as compensation or equity ownership.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**D. Conflicts of interest not specifically enumerated.** It is impractical to attempt to list in this Code all possible situations that could result in a conflict of interest. If a proposed transaction, interest, personal activity, or investment raises any concerns, questions or doubts, a Covered Officer should consult with the Chief Compliance Officer before engaging in such transaction or investment or pursuing such interest or activity. The Chief Compliance Officer shall review the facts and circumstances of the actual or potential conflict of interest in accordance with Section IV of these Procedures.

**III.** **Disclosure and Compliance** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. Each Covered Officer should familiarize himself or herself with the disclosure requirements generally applicable to the Trusts.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. Each Covered Officer should not knowingly misrepresent, or cause others to misrepresent, facts about the Trusts to others, whether within or outside the Trusts, including to the Trusts' Trustees and auditors, and to governmental regulators and self-regulatory organizations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C. Each Covered Officer should, to the extent appropriate within his or her area of responsibility, consult with other officers and employees of the Trusts, the adviser and the administrator with the goal of promoting full, fair, accurate, timely and understandable disclosure in the reports and documents the Trusts file with, or submit to, the SEC and in other public communications made by the Trusts.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**D.** It is the responsibility of each Covered Officer to promote compliance with the standards and restrictions imposed by applicable laws, rules and regulations.

**IV.** **Reporting and Accountability** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**A. Responsibilities and conduct.** Each Covered Officer must

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. Upon adoption of the Code (or thereafter as applicable, upon becoming a Covered Officer), affirm in writing to
the appropriate Board that he or she has received, read, and understands the Code;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. Annually thereafter affirm to the appropriate Board that he or she has complied with the requirements of the
Code;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. Not retaliate against any other Covered Officer or any employee of the Trusts or their affiliated persons for
reports of potential violations that are made in good faith; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. Notify the Chief Compliance Officer promptly if he or she knows of any violation of this Code. Failure to do so
is itself a violation of this Code.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**B. Chief Compliance Officer.** The Chief Compliance Officer is responsible for applying this Code to specific situations in which questions are presented under it and has the authority to interpret this Code in any particular situation. Based on its review, the Chief Compliance Officer shall advise the Covered Officer that the proposed transaction, investment, interest or activity: (i) would not violate this Code; (ii) would not violate this Code only if conducted in a particular manner and/or subject to certain conditions or safeguards; or (iii) would violate the Code and is, therefore, prohibited.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**C. Waivers.** A Covered Officer may request a waiver from a provision of this Code if there is a reasonable likelihood that a contemplated action would not involve an actual conflict of interest that this Code is designed to prevent. The Audit and Risk Oversight Committee of the Board (the "Committee") shall review and act upon any request for a waiver from any provision of the Code. The Committee shall disclose any waiver from a provision of the Code to the extent required by SEC rules or any other policy of the Trusts or VCM.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**D. Enforcing the Code of Conduct.** The Trusts will adhere to the following procedures in investigating and enforcing this Code:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. The Chief Compliance Officer will take all appropriate action to investigate any potential violations reported
to him or her;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. If, after such investigation, the Chief Compliance Officer believes that no violation has occurred, no further
action is required;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. Any matter that the Chief Compliance Officer believes is a violation shall be reported to the Committee; and

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. If the Committee concurs that a violation has occurred, it will inform the Board and make a recommendation of
appropriate courses of action. The Board will consider and take appropriate action regarding the violation. The Board may among other things, notify VCM, the Trust's administrator, or their Boards of Directors; recommend the assessment of a
monetary penalty against the Covered Person; issue a formal written reprimand to, or recommend the dismissal of, the Covered Officer; require additional training by the violator; or recommend modifications to the Trust's policies and
procedures.

**V.** **Other Policies and Procedures** 

This Code shall be the sole code of conduct adopted by the Trusts for purposes of Section 406 of the Sarbanes-Oxley Act and the rules and forms applicable to registered investment companies relating to that section. Insofar as other policies or procedures of the Trusts, the Trusts' investment adviser, principal underwriter, or other service providers govern or purport to govern the behavior or activities of the Covered Officers who are subject to this Code, they are superseded by this Code to the extent that they overlap or conflict with the provisions of this Code. The Codes of Ethics under Rule 17j-1 under the Investment Company Act, and any insider trading policies are separate policies of the Trusts, VCM, any sub-adviser or the principal underwriter that apply to the Covered Officers and others, and are not part of this Code.

**VI.** **Amendments** 

Any amendments to this Code, other than amendments to Exhibit A, must be approved or ratified by a majority vote of the Board, including a majority of the Trustees who are not "interested persons" (as defined in the Investment Company Act) (the "Independent Trustees"). Any changes to this Code will, to the extent required, will be disclosed as provided by SEC rules.

**VII.** **Confidentiality** 

All reports and records prepared or maintained pursuant to this Code will be considered confidential and shall be maintained and protected accordingly. Except as otherwise required by law or this Code, such matters shall not be disclosed to anyone other than officers and Trustees of the Trust, the Trusts' investment adviser, administrator or sub-administrator, counsel to the Trusts or counsel to the Independent Trustees.

**VIII.** **Internal Use** 

The Code is intended solely for the internal use by the Trusts and does not constitute an admission, by or on behalf of the Trusts, as to any fact, circumstance, or legal conclusion.
