Annual Report

Commodity Futures Trading Commission Registration. The Commodity Futures Trading Commission (“CFTC”) has adopted regulations that subject registered investment companies and advisers to regulation by the CFTC if a fund invests more than a prescribed level of its assets in certain CFTC-regulated instruments (including futures, certain options and swap agreements) or markets itself as providing investment exposure to such instruments. The investment adviser has claimed an exclusion from the definition of “commodity pool operator” under the Commodity Exchange Act with respect to its management of the Fund. Accordingly, neither the Fund nor the adviser with respect to the operation of the Fund is subject to CFTC regulation. Because of its management of other strategies, the Fund’s adviser is registered with the CFTC as a commodity pool operator. The adviser is also registered as a commodity trading advisor.

Managed Distribution Plan. Pursuant to an exemptive order issued by the Securities and Exchange Commission (Order), the Fund is authorized to distribute long-term capital gains to shareholders more frequently than once per year. Pursuant to the Order, the Fund’s Board of Trustees approved a Managed Distribution Plan (MDP) pursuant to which the Fund makes monthly cash distributions to common shareholders, stated in terms of a fixed amount per common share.

The Fund currently distributes monthly cash distributions equal to $0.0651 per share in accordance with the MDP. You should not draw any conclusions about the Fund’s investment performance from the amount of these distributions or from the terms of the MDP. The MDP will be subject to regular periodic review by the Fund’s Board of Trustees and the Board may amend or terminate the MDP at any time without prior notice to Fund shareholders. However, at this time there are no reasonably foreseeable circumstances that might cause the termination of the MDP.

The Fund may distribute more than its net investment income and net realized capital gains and, therefore, a distribution may include a return of capital. A return of capital distribution does not necessarily reflect the Fund’s investment performance and should not be confused with “yield” or “income.” With each distribution, the Fund will issue a notice to shareholders and a press release containing information about the amount and sources of the distribution and other related information. The amounts and sources of distributions contained in the notice and press release are only estimates and are not provided for tax purposes. The amounts and sources of the Fund’s distributions for tax purposes will be reported to shareholders on Form 1099-DIV for each calendar year.

Fund shares are not insured by the FDIC and are not deposits or other obligations of, or guaranteed by, any depository institution. Shares are subject to investment risks, including possible loss of principal invested.

Management’s Discussion of Fund Performance^†

Economic and Market Conditions

For U.S. equity investors, the 12-month period ended December 31, 2025, was another strong year. The S&P 500® Index returned 17.88%, marking a third consecutive year of double-digit gains, supported by resilient corporate earnings, enthusiasm for artificial intelligence (AI), and the Federal Reserve’s (the Fed) shift toward monetary easing.

As the period opened in January 2025, U.S. stocks continued the momentum built in late 2024. Equity gains were driven by strong demand for AI-related technologies, robust corporate results, and expectations that the Fed would begin gradually lowering interest rates as inflation cooled. Hiring remained steady, and consumer spending continued to underpin economic activity.

In early April, however, markets experienced a sharp downturn as the administration’s new tariff announcements sparked a broad selloff. Equity indexes briefly fell into correction territory amid concerns that higher import costs could slow growth and re-accelerate inflation. Sentiment stabilized later in the month after several tariff measures were modified or paused, and investors refocused on underlying corporate strength.

By mid-year, markets regained traction. AI-related capital spending accelerated, earnings remained resilient, and inflation moderated, though not as quickly as policymakers preferred. Core inflation readings held near the upper 2% range, softening investor expectations for rapid rate cuts.

A key turning point came on September 17, when the Fed delivered its first rate cut of the year. Additional quarter-point reductions followed in October and December, bringing the federal funds rate closer to a neutral stance. While policymakers acknowledged persistent inflationary pressures, they emphasized growing softness in the labor market as justification for easing.

U.S. equities ended the year on solid footing despite a subdued December. A brief late-year pullback reflected profit-taking and uncertainty about the pace of future rate cuts, but AI-related companies and large-cap technology remained notable performance leaders. The Nasdaq Composite Index and Dow Jones Industrial Average® also delivered strong full-year gains, underscoring the durability of U.S. equity performance.

Overall, 2025 was marked by policy-driven volatility but ultimately strong results, as investors balanced tariff-related disruptions, mixed inflation data, and shifting rate expectations. Despite periods of turbulence, major U.S. equity indexes advanced meaningfully for the year, supported by corporate resilience and powerful secular trends in technology and AI.

Fund Performance

For the 12-month period ended December 31, 2025, Eaton Vance Risk-Managed Diversified Equity Income Fund (the Fund) returned 8.71% at net asset value of its common shares (NAV), underperforming its equity benchmark, the S&P 500® Index (the Index), which returned 17.88%; and outperforming its options benchmark, the Cboe S&P 500 95-110 Collar Index^SM, which returned 8.40%.

The Fund’s collared-options strategy (the options strategy) was the largest detractor from Fund performance relative to the Index during the period. The options strategy may be beneficial during times of market weakness and higher volatility, but may detract from performance relative to the Index during periods of market strength, since it seeks to buy downside protection at the expense of upside potential.

For much of the period, the Index moved higher with a few sudden pullbacks due to changing market events. Market volatility -- as measured by the Cboe Volatility Index®, or VIX -- was largely subdued during the period. However, in April 2025, equity markets experienced a historic spike in volatility, with a market sell-off attributed to the “Liberation Day” announcement of tariffs. While the Fund’s downside protection was helpful during this market pullback, the stock market’s overall strength during the period created net losses within the Fund’s options strategy.

Meanwhile, the Fund’s common stock portfolio underperformed the Index during the period, detracting from Index-relative returns.

The largest individual stock detractor from performance relative to the Index was an out-of-index position in Shift4 Payments, Inc., a supplier of integrated payment and commerce technology for merchants. Shift4 Payments’ stock fell in 2025 due to earnings misses, integration concerns around its Global Blue acquisition, valuation pressure, and broader payment-sector headwinds.

On a sector basis, stock selections in the industrials, financials and the real estate sectors detracted from Fund performance relative to the Index during the period.

The largest contributor to performance relative to the Index was an out-of-index position in Mr. Cooper Group, Inc., a leading U.S. mortgage servicer providing home loan servicing and origination solutions. The company’s stock price was supported by its merger with Rocket Companies, Inc., which is America’s largest lender.

See Endnotes and Additional Disclosures in this report.

Past performance is no guarantee of future results. Returns are historical and are calculated net of management fees and other expenses by determining the percentage change in net asset value (NAV) or market price (as applicable) with all distributions reinvested in accordance with the Fund’s Dividend Reinvestment Plan. Furthermore, returns do not reflect the deduction of taxes that shareholders may have to pay on Fund distributions or upon the sale of Fund shares. Performance at market price will differ from performance at NAV due to variations in the Fund’s market price versus NAV, which may reflect factors such as fluctuations in supply and demand for Fund shares, changes in Fund distributions, shifting market expectations for the Fund’s future returns and distribution rates, and other considerations affecting the trading prices of closed-end funds. Investment return and principal value will fluctuate so that shares, when sold, may be worth more or less than their original cost. Performance for periods less than or equal to one year is cumulative. Performance is for the stated time period only; due to market volatility, current Fund performance may be lower or higher than the quoted return. For performance as of the most recent month-end, please refer to eatonvance.com.

On a sector basis, stock selections and an underweight position in the consumer staples sector and stock selections in the health care and consumer discretionary sectors all contributed to Fund performance relative to the Index during the period.

Fund Distributions

Pursuant to an exemptive order issued by the Securities and Exchange Commission (the Order), the Fund is authorized to distribute long-term capital gains to shareholders more frequently than once per year. Pursuant to the Order, the Fund’s Board of Trustees approved a Managed Distribution Plan (MDP) pursuant to which the Fund makes monthly cash distributions to common shareholders. The Fund’s MDP had no effect on the Fund’s investment strategy during the most recent fiscal year and is not expected to have an effect in future periods, but distributions in excess of Fund returns will cause its per share NAV to erode. Investors should not draw any conclusions about the Fund’s investment performance from the amount of its distribution or from the terms of its MDP.

For the period from January 1, 2025 to December 31, 2025, the Fund made monthly distributions of $0.0651 per share. The Fund’s distributions may be comprised of amounts characterized for federal income tax purposes as qualified and non-qualified ordinary dividends, capital gains and non-dividend distributions, also known as return of capital distributions. The federal income tax character of distributions is determined after the end of the calendar year and reported to shareholders on the Internal Revenue Service’s form 1099-DIV. For additional information, see Note 2 in the Notes to Financial Statements herein.

Risk-Managed Diversified Equity Income Fund

December 31, 2025

The Fund's Investment Objectives, Principal Strategies and Principal Risks^‡

Investment Objectives. The Fund’s primary investment objective is to provide current income and gains, with a secondary objective of capital appreciation. In pursuing its investment objectives, the Fund evaluates returns on an after-tax basis, seeking to minimize and defer shareholder federal income taxes.

Principal Strategies. Under normal market conditions, the Fund’s investment program consists primarily of owning a diversified portfolio of common stocks and employing a variety of options strategies. The Fund seeks to earn high levels of tax-advantaged income and gains by (1) investing in stocks that pay dividends that qualify for favorable federal income tax treatment, (2) writing (selling) put options on individual stocks deemed attractive for purchase, and/or (3) writing (selling) stock index call options with respect to a portion of its common stock portfolio value. To reduce the Fund’s risk of loss due to a decline in the value of the general equity market, the Fund intends to purchase index put options with respect to a substantial portion of the value of its common stock holdings and stocks subject to written put options.

Under normal market conditions, the Fund invests at least 80% of its total assets in a combination of (1) dividend-paying common stocks, (2) common stocks the value of which is subject to written put options on individual stocks, and (3) common stocks the value of which is subject to written index call options. In addition, under normal market conditions, the Fund purchases index put options with respect to at least 80% of the value of its investments in common stocks. The Fund may consider investments in stocks that pay dividends that qualify for federal income taxation at rates applicable to long-term capital gains. The Fund generally intends to buy put options and write call options on one or more broad-based stock indices that the investment adviser believes collectively approximate the characteristics of its common stock portfolio (or that portion of its portfolio against which options are purchased and written). The Fund intends to buy put options and write call options primarily on the S&P 500® Index (the “S&P 500”), and may also buy put options and write call options on other domestic and foreign stock indices. The Fund’s current options strategy consists of purchasing out-of-the-money S&P 500 put options and selling out-of-the-money S&P 500 call options on all or substantially all of the value of the Fund’s common stock portfolio. Purchasing index put options provides protection against loss of principal value during periods of market weakness and selling index call options generates premium income. The Fund generally intends to purchase short-dated (generally 28-day) index put options and sell index call options of the same term, staggering roll dates across the options portfolio. The indices on which the Fund buys put options and writes call options may vary as a result of changes in the availability and liquidity of various listed index options, changes in stock portfolio holdings, the Adviser’s evaluation of equity market conditions and other factors. The buying of index put options will reduce the Fund’s cash available for distribution from other sources, including from selling put options on individual stocks and index call options.

The Fund invests primarily in common stocks of United States issuers. The Fund may invest up to 40% of its total assets in securities of foreign issuers, including securities evidenced by American Depositary Receipts (“ADRs”), Global Depositary Receipts (“GDRs”) and European Depositary Receipts (“EDRs”). The Fund may invest up to 5% of its total assets in securities of emerging market issuers. The Fund expects that its assets will normally be invested across a broad range of industries and market sectors. The Fund may not invest 25% or more of its total assets in the securities of issuers in any single industry. Eaton Vance generally considers mid-capitalization companies to be those companies having market capitalizations within the range of capitalizations for the S&P MidCap 400® Index (the “S&P MidCap 400® ”). As of December 31, 2025, the median market capitalization of companies in the S&P MidCap 400® was $7.6 billion. Market capitalizations of companies within the S&P MidCap 400® are subject to change.

During unusual market circumstances, the Fund may invest up to 100% of its assets in cash or cash equivalents temporarily, which may be inconsistent with the Fund’s investment objectives and other policies.

Principal Risks

Market Discount Risk. As with any security, the market value of the Fund’s common shares may increase or decrease from the amount initially paid for the common shares. The Fund’s common shares have traded both at a premium and at a discount relative to NAV. The shares of closed-end management investment companies frequently trade at a discount from their NAV. This is a risk separate and distinct from the risk that the Fund’s NAV may decrease.

Investment and Market Risk. An investment in the Fund’s common shares is subject to investment risk, including the possible loss of the entire principal amount invested. An investment in common shares represents an indirect investment in the securities owned by the Fund, which are generally traded on a securities exchange or in the over-the-counter markets. The value of these securities, like other market investments, may move up or down, sometimes rapidly and unpredictably. Because the Fund may sell stock index call options on a portion of its common stock portfolio value, the Fund’s appreciation potential from equity market performance may be more limited than if the Fund did not engage in selling stock index call options. Because the Fund may sell put options on individual stocks, the Fund’s exposure to loss from a decline in the value of such stocks may increase. To the extent that the individual stocks held by the Fund and/or the stocks subject to written put options decrease in value more than the index or indices on which the Fund has purchased put options, the strategy of purchasing index put options will provide only limited protection with respect to the value of the Fund’s assets and may result in worse performance for the Fund than if it did not buy index put options. The common shares at any point in time may be worth less than the original investment, even after taking into account any reinvestment of distributions.

The value of investments held by the Fund may increase or decrease in response to social, economic, political, financial, public health crises or other disruptive events (whether real, expected or perceived) in the U.S. and global markets and include events such as war, natural disasters, epidemics and pandemics, terrorism, conflicts and social unrest. These events may negatively impact broad segments of businesses and populations and may exacerbate pre-existing risks to the Fund. The frequency and magnitude of resulting changes in the value of the Fund’s investments cannot be predicted. Certain securities and other investments held by the Fund may experience increased volatility, illiquidity, or other potentially adverse effects in reaction to changing

market conditions. Monetary and/or fiscal actions taken by U.S. or foreign governments to stimulate or stabilize the global economy may not be effective and could lead to high market volatility. No active trading market may exist for certain investments held by the Fund, which may impair the ability of the Fund to sell or to realize the current valuation of such investments in the event of the need to liquidate such assets.

Issuer Risk. The value of securities held by the Fund may decline for a number of reasons that directly relate to the issuer, such as management performance, financial leverage and reduced demand for the issuer’s goods and services.

Equity Securities Risk. The value of equity securities and related instruments may decline in response to adverse changes in the economy or the economic outlook; deterioration in investor sentiment; interest rate, currency, and commodity price fluctuations; adverse geopolitical, social or environmental developments; issuer and sector-specific considerations; unexpected trading activity among retail investors; or other factors. Market conditions may affect certain types of stocks to a greater extent than other types of stocks. If the stock market declines in value, the value of the Fund’s equity securities will also likely decline. Although prices can rebound, there is no assurance that values will return to previous levels.

Limitations on Equity Market Risk Management Strategy. To manage the risk of a decline in the value of the general equity market, the Fund purchases index put options on a substantial portion of the value of its common stock holdings. As the purchaser of an index put option, the Fund would pay to the writer (seller) of the option cash (the premium), and the Fund has the right to receive from the seller the amount by which the cash value of the index is below the exercise price as of the valuation date of the option. If the Fund exercises the index put option, the seller would pay the Fund the difference between the exercise price and the value of the index. There are a number of limitations on the extent to which common shareholders of the Fund may benefit from this risk management strategy.

First, holding an index put option generally provides a hedge against a decline in the applicable index to levels below the exercise price on the option. A decline in the index to a level above the exercise price would result in the option expiring worthless if held until expiration. Generally, the Fund intends to buy index put options that are “out-of-the-money” (i.e., the exercise price generally is below the current level of the applicable index when the option is purchased). Options that are more “out-of-the-money” provide the Fund with less protection against a decline in the applicable index.

Second, there is a risk that the value of the stock indices subject to purchased put options will not correlate with the value of the Fund’s portfolio holdings. The Fund intends to buy put options on one or more broad-based stock indices that the Adviser believes collectively approximate the characteristics of the Fund’s common stock portfolio (or that portion of its portfolio against which put options are acquired). The Fund will not, however, hold stocks that fully replicate the indices on which it buys put options. Due to tax considerations, the Fund intends to generally limit the overlap between its stock holdings (and any subset thereof) and each index on which it has outstanding options positions to less than 70% on an ongoing basis. The Fund’s stock holdings will normally include stocks not included in the indices on which it buys put options. Accordingly, the value of the indices may remain flat or increase in value at times when the Fund’s portfolio holdings are decreasing in value. Similarly, the indices may decrease in value but to a lesser extent than the Fund’s portfolio holdings. In such cases, the index put options would provide only a limited hedge against a decline in the value of the Fund’s portfolio holdings and may result in worse performance for the Fund than if it did not buy index put options. The use of index put options cannot serve as a complete hedge since the price movement of the indices underlying the options will not necessarily follow the price movements of the Fund’s portfolio holdings. Correlation risks are also presented in connection with the Fund’s selling of put options on individual stocks and purchasing index puts to hedge the associated increase in market risk. Purchasing index put options with respect to single stock put options written does not protect the Fund against the risk that the stocks against which put options are written decrease in value relative to the index on which put options are purchased and may result in greater costs and losses to the Fund than a strategy that does not involve such hedging.

Third, the Fund may in certain circumstances hold stock index put options with respect to only a portion of the value of its common stock holdings, subject to the condition that, under normal market conditions, the Fund will hold index put options with respect to at least 80% of the value of its investments in common stocks. The portion of the Fund’s portfolio value against which index put options are not acquired will not benefit from this risk management strategy.

Index put options can be highly volatile instruments. This may cause options positions held to react to market changes differently than the Fund’s portfolio securities and stocks subject to written put options. A put option acquired by the Fund and not sold prior to expiration will expire worthless if the price of the index at expiration exceeds the exercise price of the option, thereby causing the Fund to lose its entire investment in the option. If restrictions on exercise were imposed, the Fund might be unable to exercise an option it had purchased. If the Fund were unable to close out an option that it had purchased, it would have to exercise the option in order to realize any profit or the option may expire worthless.

Option Strategy Risk. The Fund’s option strategy seeks to take advantage of, and its effectiveness is dependent on, a general excess of option price implied volatilities for the S&P 500 over realized index volatilities. This market observation is often attributed to an excess of natural buyers over natural sellers of S&P 500 options. There can be no assurance that this imbalance will apply in the future over specific periods or generally. It is possible that the imbalance could decrease or be eliminated by actions of investors, including the Fund, that employ strategies seeking to take advantage of the imbalance, which could have an adverse effect on the Fund’s ability to achieve its investment objectives.

Risk of Selling Index Call Options. The purchaser of an index call option has the right to any appreciation in the value of the index over the exercise price of the call option as of the valuation date of the option. Because their exercise is settled in cash, sellers of index call options such as the Fund cannot provide in advance for their potential settlement obligations by acquiring and holding the underlying securities. The Fund intends to mitigate the risks of its options activities by holding a diversified portfolio of stocks that the Fund’s investment adviser believes collectively approximate the characteristics of the

indices on which options are written. The Fund will not, however, hold stocks that fully replicate the indices on which it writes call options. Due to tax considerations, the Fund intends to generally limit the overlap between its stock holdings (and any subset thereof) and each index on which it has outstanding options positions to less than 70% on an ongoing basis. The Fund’s stock holdings will normally include stocks not included in the indices on which it writes call options. Consequently, the Fund bears the risk that the performance of its stock portfolio will vary from the performance of the indices on which it writes call options. As the writer of index call options, the Fund will forgo, during the option’s life, the opportunity to profit from increases in the value of the applicable index above the sum of the option premium received and the exercise price of the call option, but retains the risk of loss, minus the option premium received, should the value of the applicable index decline. When a call option is exercised, the Fund will be required to deliver an amount of cash determined by the excess of the value of the applicable index at contract termination over the exercise price of the option. If the value of the index increases over the option’s life, the premium income generated from selling the index call option may not be enough to compensate for the difference between the exercise price of the index call option and the increased index value. Thus, the exercise of index call options sold by the Fund may require the Fund to sell portfolio securities to generate cash at inopportune times or for unattractive prices and the Fund may lose money. The trading price of options may be adversely affected if the market for such options becomes less liquid or smaller. The Fund may close out a call option by buying the option instead of letting it expire or be exercised. There can be no assurance that a liquid market will exist when the Fund seeks to close out a call option position by buying the option.

Risks of Selling Put Options on Individual Stocks. The Fund may write put options on individual stocks that the Adviser believes are attractive for purchase at prices at or above the exercise price of the put options written. The purchaser of a put option assumes the right to sell (put) the stock to the seller of the option at a specified price (the exercise price) on or before the expiration date of the option. If the value of the stock on the option expiration date is at or below the exercise price of the option, the Fund may be obligated to purchase the stock at the exercise price. In the event of a substantial depreciation in the value of the underlying stock, the Fund may incur a substantial loss.

Options Risks Generally. A decision as to whether, when and how to use options involves the exercise of skill and judgment, and even a well-conceived and well-executed options program may be adversely affected by market behavior or unexpected events. Successful options strategies may require the anticipation of future movements in securities prices, interest rates and other economic factors. No assurances can be given that the Adviser’s judgments in this respect will be correct.

The trading price of options may be adversely affected if the market for such options becomes less liquid or smaller. The Fund may close out a written option position by buying the option instead of letting it expire or be exercised. Similarly, the Fund may close out a purchased option position by selling the option instead of holding until exercise. There can be no assurance that a liquid market will exist when the Fund seeks to close out an option position by buying or selling the option. Reasons for the absence of a liquid secondary market on an exchange include the following: (i) there may be insufficient trading interest in certain options; (ii) restrictions may be imposed by an exchange on opening transactions or closing transactions or both; (iii) trading halts, suspensions or other restrictions may be imposed with respect to particular classes or series of options; (iv) unusual or unforeseen circumstances may interrupt normal operations on an exchange; (v) the facilities of an exchange or the Options Clearing Corporation (the “OCC”) may not at all times be adequate to handle current trading volume; or (vi) one or more exchanges could, for economic or other reasons, decide or be compelled to discontinue the trading of options (or a particular class or series of options) at some future date. If trading were discontinued, the secondary market on that exchange (or in that class or series of options) would cease to exist. However, outstanding options on that exchange that had been issued by the OCC as a result of trades on that exchange would continue to be exercisable in accordance with their terms.

The Fund’s options positions will be marked to market daily. The hours of trading for options may not conform to the hours during which common stocks held by the Fund are traded. To the extent that the options markets close before the markets for securities, significant price and rate movements can take place in the securities markets that would not be reflected concurrently in the options markets. The value of index options is affected by changes in the value and dividend rates of the securities represented in the underlying index, changes in interest rates, changes in the actual or perceived volatility of the associated index and the remaining time to the options’ expiration, as well as trading conditions in the options market. Similarly, the value of single stock options is affected by changes in the value and dividend rate of the underlying stock, changes in interest rates, changes in the actual or perceived volatility of the associated stock and the remaining time to the options’ expiration, as well as options market trading conditions.

The Fund’s options transactions will be subject to limitations established by each of the exchanges, boards of trade or other trading facilities on which such options are traded. These limitations govern the maximum number of options in each class which may be written or purchased by a single investor or group of investors acting in concert, regardless of whether the options are written or purchased on the same or different exchanges, boards of trade or other trading facilities or are held or written in one or more accounts or through one or more brokers. Thus, the number of options which the Fund may write or purchase may be affected by options written or purchased by other investment advisory clients of the Adviser. An exchange, board of trade or other trading facility may order the liquidation of positions found to be in excess of these limits, and may impose certain other sanctions. The Fund will not write “naked” or uncovered call options.

To the extent that the Fund buys or writes options on indices based upon foreign stocks, the Fund generally intends to buy or sell options on broad-based foreign country and/or regional stock indices that are listed for trading in the United States or which otherwise qualify as “section 1256 contracts” under the Code. Options on foreign indices that are listed for trading in the United States or which otherwise qualify as “section 1256 contracts” under the Code may trade in substantially lower volumes and with substantially wider bid-ask spreads than other options contracts on the same or similar indices that

Gain or loss on index options not qualifying as “section 1256 contracts” under the Code would be realized upon disposition, lapse or settlement of the positions and, generally, would be treated as short-term gain or loss.

OTC Options Risks. OTC options involve risk that the issuer or counterparty will fail to perform its contractual obligations. Participants in these markets are typically not subject to credit evaluation and regulatory oversight as are members of “exchange based” markets. Options traded in OTC markets will not be issued, guaranteed or cleared by the OCC. By engaging in option transactions in these markets, the Fund may take a credit risk with regard to parties with which it trades and also may bear the risk of settlement default. These risks may differ materially from those involved in exchange-traded transactions, which generally are characterized by clearing organization guarantees, daily marking-to-market and settlement, and segregation and minimum capital requirements applicable to intermediaries. Transactions entered into directly between two counterparties generally do not benefit from these protections, which in turn may subject the Fund to the risk that a counter-party will not settle a transaction in accordance with agreed terms and conditions because of a dispute over the terms of the contract or because of a credit or liquidity problem. Such “counterparty risk” is increased for contracts with longer maturities when events may intervene to prevent settlement. The ability of the Fund to transact business with any one or any number of counterparties, the lack of any independent evaluation of the counterparties or their financial capabilities, and the absence of a regulated market to facilitate a settlement may increase the potential for losses to the Fund.

Derivatives Risk. The Fund’s exposure to derivatives involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other investments. The use of derivatives can lead to losses because of adverse movements in the price or value of the security, instrument, index, currency, commodity, economic indicator or event underlying a derivative (“reference instrument”), due to failure of a counterparty or due to tax or regulatory constraints. Derivatives may create leverage in the Fund, which represents a non-cash exposure to the underlying reference instrument. Leverage can increase both the risk and return potential of the Fund. Derivatives risk may be more significant when derivatives are used to enhance return or as a substitute for a cash investment position, rather than solely to hedge the risk of a position held by the Fund. Use of derivatives involves the exercise of specialized skill and judgment, and a transaction may be unsuccessful in whole or in part because of market behavior or unexpected events. Changes in the value of a derivative (including one used for hedging) may not correlate perfectly with the underlying reference instrument. Derivative instruments traded in over-the-counter markets may be difficult to value, may be illiquid, and may be subject to wide swings in valuation caused by changes in the value of the underlying reference instrument. If a derivative’s counterparty is unable to honor its commitments, the value of Fund shares may decline and the Fund could experience delays in (or be unable to achieve) the return of collateral or other assets held by the counterparty. The loss on derivative transactions may substantially exceed the initial investment. A derivative investment also involves the risks relating to the reference instrument underlying the investment.

Tax-Sensitive Investing Risk. The Fund may hold a security in order to achieve more favorable tax-treatment or to sell a security in order to create tax losses. The Fund’s utilization of various tax-management techniques may be curtailed or eliminated by tax legislation, regulation or interpretations. The Fund may not be able to minimize taxable distributions to shareholders and a portion of the Fund’s distributions may be taxable.

Tax Risk. Although the Fund seeks to minimize and defer the federal income taxes incurred by common shareholders in connection with their investment in the Fund, there can be no assurance that it will be successful in this regard. The tax treatment and characterization of the Fund’s distributions may change over time due to changes in the Fund’s mix of investment returns and changes in the federal tax laws, regulations and administrative and judicial interpretations, potentially with retroactive effect. The Fund’s investment program and the tax treatment of Fund distributions may be affected by U.S. Internal Revenue Service interpretations of the Internal Revenue Code of 1986, as amended, and future changes in tax laws and regulations. While the Fund generally intends to use a variety of techniques and strategies designed to minimize and defer the federal income taxes incurred by common shareholders in connection with their investment in the Fund, certain of the Fund’s investment practices are subject to complex federal income tax provisions that may, among other things, cause common shareholders to pay more tax than they otherwise would have, or to accelerate common shareholders’ recognition of taxable income or gains.

Risks of Investing in Smaller and Mid-Sized Companies. The Fund may make investments in stocks of companies whose market capitalization is considered middle sized or “mid-cap.” Smaller and mid-sized companies are generally subject to greater price fluctuations, limited liquidity, higher transaction costs and higher investment risk than the stocks of larger, more established companies. Such companies may have limited product lines, markets or financial resources, may be dependent on a limited management group, and may lack substantial capital reserves or an established performance record. There may be generally less publicly available information about such companies than for larger, more established companies. Stocks of these companies frequently have lower trading volumes making them more volatile and potentially more difficult to value.

Foreign Investment Risk. Foreign investments can be adversely affected by political, economic and market developments abroad, including the imposition of economic and other sanctions by the United States or another country against a particular country or countries, organizations, entities and/or individuals. There may be less publicly available information about foreign issuers because they may not be subject to reporting practices, requirements or regulations comparable to those to which United States companies are subject. Adverse changes in investment regulations, capital requirements or exchange controls could adversely affect the value of the Fund’s investments. Foreign markets may be smaller, less liquid and more volatile than the major markets in the United States, and as a result, Fund share values may be more volatile. Trading in foreign markets typically involves higher expense than trading in the United States. The Fund may have difficulties enforcing its legal or contractual rights in a foreign country. Depositary receipts are subject to many of the risks associated with investing directly in foreign instruments, including the political and economic risks of the underlying issuer’s country and, in the case of depositary receipts traded on foreign markets, currency risk.

The Fund's Investment Objectives, Principal Strategies and Principal Risks^‡ — continued

Emerging Markets Investment Risk. Investment markets within emerging market countries are typically smaller, less liquid, less developed and more volatile than those in more developed markets like the United States, and may be focused in certain sectors. Emerging market securities often involve greater risks than developed market securities. The information available about an emerging market issuer may be less reliable than for comparable issuers in more developed capital markets.

Focused Investment Risk. To the extent the Fund has substantial investments in a relatively small number of securities or issuers, or a particular market, industry, group of industries, country, region, group of countries, asset class or sector the Fund’s performance will be more susceptible to any single economic, market, political, or regulatory occurrence affecting those particular securities or issuers or that particular market, industry, group of industries, country, region, group of countries, assets class, or sector than a fund that invests more broadly.

Currency Risk. Exchange rates for currencies fluctuate daily. The value of foreign investments may be affected favorably or unfavorably by changes in currency exchange rates in relation to the U.S. dollar. Currency markets generally are not as regulated as securities markets and currency transactions are subject to settlement, custodial and other operational risks.

Interest Rate Risk. The premiums from writing options and amounts available for distribution from the Fund’s options activities may decrease in declining interest rate environments. The value of the Fund’s common stock investments may also be influenced by changes in interest rates. Higher yielding stocks and stocks of issuers whose businesses are substantially affected by changes in interest rates may be particularly sensitive to interest rate risk.

Liquidity Risk. The Fund is exposed to liquidity risk when trading volume, lack of a market maker or trading partner, large position size, market conditions, or legal restrictions impair its ability to sell particular investments or to sell them at advantageous market prices. Consequently, the Fund may have to accept a lower price to sell an investment or continue to hold it or keep the position open, sell other investments to raise cash or abandon an investment opportunity, any of which could have a negative effect on the Fund’s performance. These effects may be exacerbated during times of financial or political stress.

Inflation Risk. Inflation risk is the risk that the value of assets or income from investments will be worth less in the future as inflation decreases the value of money. As inflation increases, the real value of the common shares and distributions thereon can decline.

Counterparty Risk. A financial institution or other counterparty with whom the Fund does business (such as trading or as a derivatives counterparty), or that underwrites, distributes or guarantees any instruments that the Fund owns or is otherwise exposed to, may decline in financial condition and become unable to honor its commitments. This could cause the value of Fund shares to decline or could delay the return or delivery of collateral or other assets to the Fund. Counterparty risk is increased for contracts with longer maturities.

Leverage Risk. Certain Fund transactions may give rise to leverage. Leverage can result from a non-cash exposure to an underlying reference instrument. Leverage can also result from borrowings or issuance of preferred shares. Leverage can increase both the risk and return potential of the Fund. The use of leverage may cause the Fund to maintain liquid assets or liquidate portfolio positions when it may not be advantageous to do so to satisfy its obligations. Leverage may cause the Fund’s share price to be more volatile than if it had not been leveraged, as certain types of leverage may exaggerate the effect of any increase or decrease in the value of the Fund’s portfolio securities. The Fund may not be able to adjust its use of leverage rapidly enough to respond to interest rate volatility, inflation, and other changing market conditions. As a result, the Fund’s use of leverage may have a negative impact on the Fund’s performance from time to time. The loss on leveraged investments may substantially exceed the initial investment.

Risks Associated with Active Management. The success of the Fund’s investment strategy depends on portfolio management’s successful application of analytical skills and investment judgment. Active management involves subjective decisions and there is no guarantee that such decisions will produce the desired results or expected returns.

Recent Market Conditions. Both U.S. and international markets have experienced significant volatility in recent months and years. As a result of such volatility, investment returns may fluctuate significantly. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

The U.S. government and the U.S. Federal Reserve, as well as certain foreign governments and central banks, have from time to time taken steps to support financial markets. The U.S. government and the U.S. Federal Reserve may, conversely, reduce market support activities, including by taking action intended to increase certain interest rates. This and other government intervention may not work as intended, particularly if the efforts are perceived by investors as being unlikely to achieve the desired results. Changes in government activities in this regard, such as changes in interest rate policy, can negatively affect financial markets generally, increase market volatility and reduce the value and liquidity of securities in which the Fund invests.

Some countries, including the United States, have adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with trade negotiations between the United States and China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

Regulators in the United States have proposed and adopted a number of changes to regulations involving the markets and issuers, some of which apply to the Fund. The full effect of various newly adopted regulations is not currently known. Additionally, it is not currently known whether any of the proposed regulations will be adopted. However, due to the scope of regulations being proposed and adopted, certain of these changes to regulation could limit the Fund’s ability to pursue its investment strategies or make certain investments, may make it more costly for it to operate, or adversely impact performance.

Tensions, war, or open conflict between nations, such as between Russia and Ukraine, in the Middle East, or in eastern Asia could affect the economies of many nations, including the United States. The duration of ongoing hostilities and any sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

There is widespread concern about the potential effects of global climate change on property and security values. Certain issuers, industries and regions may be adversely affected by the impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

Cybersecurity Risk. With the increased use of technologies by Fund service providers to conduct business, such as the Internet, the Fund is susceptible to operational, information security and related risks. In general, cyber incidents can result from deliberate attacks or unintentional events. Cybersecurity failures by or breaches of the Fund’s investment adviser or administrator and other service providers (including, but not limited to, the custodian or transfer agent), and the issuers of securities in which the Fund invests, may disrupt and otherwise adversely affect their business operations. This may result in financial losses to the Fund, impede Fund trading, interfere with the Fund’s ability to calculate its net asset value, interfere with the Fund’s ability to transact business or cause violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs.

Market Disruption. Global instability, war, geopolitical tensions and terrorist attacks in the United States and around the world have previously resulted, and may continue to result in market volatility and may have long-term effects on the United States and worldwide financial markets and may cause further economic uncertainties in the United States and worldwide. The Fund cannot predict the effects of significant future events on the global economy and securities markets. A similar disruption of the financial markets could impact interest rates, auctions, secondary trading, ratings, credit risk, inflation and other factors relating to the common shares.

Anti-Takeover Provisions. The Fund’s Agreement and Declaration of Trust and Amended and Restated By-Laws include provisions that could have the effect of making it more difficult to acquire control of the Fund and/or to change the composition of its Board.

General Fund Investing Risks. The Fund is not a complete investment program and there is no guarantee that the Fund will achieve its investment objectives. It is possible to lose money by investing in the Fund. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

There have been no material changes to the Fund’s investment objectives or principal investment strategies since December 31, 2024.

Risk-Managed Diversified Equity Income Fund

Notes to Financial Statements

1 Significant Accounting Policies

Eaton Vance Risk-Managed Diversified Equity Income Fund (the Fund) is a Massachusetts business trust registered under the Investment Company Act of 1940, as amended (the 1940 Act), as a diversified, closed-end management investment company. The Fund’s primary investment objective is to provide current income and gains, with a secondary objective of capital appreciation.

The following is a summary of significant accounting policies of the Fund. The policies are in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP). The Fund is an investment company and follows accounting and reporting guidance in the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946.

A Investment Valuation—The following methodologies are used to determine the market value or fair value of investments.

Equity Securities. Equity securities listed on a U.S. securities exchange generally are valued at the last sale or closing price on the day of valuation or, if no sales took place on such date, at the mean between the closing bid and ask prices on the exchange where such securities are principally traded. Equity securities listed on the NASDAQ National Market System are valued at the NASDAQ official closing price. Unlisted or listed securities for which closing sales prices or closing quotations are not available are valued at the mean between the latest available bid and ask prices.

Derivatives. U.S. exchange-traded options are valued at the mean between the bid and ask prices at valuation time as reported by the Options Price Reporting Authority. Non-U.S. exchange-traded options and over-the-counter options are valued by a third party pricing service using techniques that consider factors including the value of the underlying instrument, the volatility of the underlying instrument and the period of time until option expiration.

Foreign Securities and Currencies. Foreign securities and currencies are valued in U.S. dollars, based on foreign currency exchange rate quotations supplied by a third party pricing service. The pricing service uses a proprietary model to determine the exchange rate. Inputs to the model include reported trades and implied bid/ask spreads. The daily valuation of exchange-traded foreign securities generally is determined as of the close of trading on the principal exchange on which such securities trade. Events occurring after the close of trading on foreign exchanges may result in adjustments to the valuation of foreign securities to more accurately reflect their fair value as of the close of regular trading on the New York Stock Exchange. When valuing foreign equity securities that meet certain criteria, the Fund's Trustees have approved the use of a fair value service that values such securities to reflect market trading that occurs after the close of the applicable foreign markets of comparable securities or other instruments that have a strong correlation to the fair-valued securities.

Other. Investments in management investment companies (including money market funds) that do not trade on an exchange are valued at the net asset value as of the close of each business day.

Fair Valuation. In connection with Rule 2a-5 of the 1940 Act, the Trustees have designated the Fund’s investment adviser as its valuation designee. Investments for which valuations or market quotations are not readily available or are deemed unreliable are valued by the investment adviser, as valuation designee, at fair value using methods that most fairly reflect the security’s “fair value”, which is the amount that the Fund might reasonably expect to receive for the security upon its current sale in the ordinary course. Each such determination is based on a consideration of relevant factors, which are likely to vary from one pricing context to another. These factors may include, but are not limited to, the type of security, the existence of any contractual restrictions on the security’s disposition, the price and extent of public trading in similar securities of the issuer or of comparable companies or entities, quotations or relevant information obtained from broker/dealers or other market participants, information obtained from the issuer, analysts, and/or the appropriate stock exchange (for exchange-traded securities), an analysis of the company’s or entity’s financial statements, and an evaluation of the forces that influence the issuer and the market(s) in which the security is purchased and sold.

B Investment Transactions—Investment transactions for financial statement purposes are accounted for on a trade date basis. Realized gains and losses on investments sold are determined on the basis of identified cost.

C Income—Dividend income is recorded on the ex-dividend date for dividends received in cash and/or securities. However, if the ex-dividend date has passed, certain dividends from foreign securities are recorded as the Fund is informed of the ex-dividend date. Withholding taxes on foreign dividends and capital gains have been provided for in accordance with the Fund's understanding of the applicable countries' tax rules and rates.

D Federal and Other Taxes—The Fund’s policy is to comply with the provisions of the Internal Revenue Code applicable to regulated investment companies and to distribute to shareholders each year substantially all of its net investment income, and all or substantially all of its net realized capital gains. Accordingly, no provision for federal income or excise tax is necessary. As of December 31, 2025, the Fund had no uncertain tax positions that would require financial statement recognition, de-recognition, or disclosure. The Fund files a U.S. federal income tax return annually after its fiscal year-end, which is subject to examination by the Internal Revenue Service for a period of three years from the date of filing.

During this reporting period, the Fund adopted FASB Accounting Standards Update No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (ASU 2023-09), which requires annual disclosure of the amount of income taxes paid (net of refunds received) disaggregated by federal, state, and foreign taxes, and further disaggregated by individual jurisdiction in which income taxes paid is equal to or greater than 5% of total income taxes paid.

The adoption of ASU 2023-09 did not result in any changes to the Fund’s financial statement presentation or disclosure.

Notes to Financial Statements — continued

E Foreign Currency Translation—Investment valuations, other assets, and liabilities initially expressed in foreign currencies are translated each business day into U.S. dollars based upon current exchange rates. Purchases and sales of foreign investment securities and income and expenses denominated in foreign currencies are translated into U.S. dollars based upon currency exchange rates in effect on the respective dates of such transactions. Recognized gains or losses on investment transactions attributable to changes in foreign currency exchange rates are recorded for financial statement purposes as net realized gains and losses on investments. That portion of unrealized gains and losses on investments that results from fluctuations in foreign currency exchange rates is not separately disclosed.

F Use of Estimates—The preparation of the financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of income and expense during the reporting period. Actual results could differ from those estimates.

G Indemnifications—Under the Fund's organizational documents, its officers and Trustees may be indemnified against certain liabilities and expenses arising out of the performance of their duties to the Fund. Under Massachusetts law, if certain conditions prevail, shareholders of a Massachusetts business trust (such as the Fund) could be deemed to have personal liability for the obligations of the Fund. However, the Fund's Declaration of Trust contains an express disclaimer of liability on the part of Fund shareholders and the By-laws provide that the Fund shall assume, upon request by the shareholder, the defense on behalf of any Fund shareholders. Moreover, the By-laws also provide for indemnification out of Fund property of any shareholder held personally liable solely by reason of being or having been a shareholder for all loss or expense arising from such liability. Additionally, in the normal course of business, the Fund enters into agreements with service providers that may contain indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Fund that have not yet occurred.

H Written Options—Upon the writing of a call or a put option, the premium received by the Fund is included in the Statement of Assets and Liabilities as a liability. The amount of the liability is subsequently marked-to-market to reflect the current market value of the option written, in accordance with the Fund’s policies on investment valuations discussed above. Premiums received from writing options which expire are treated as realized gains. Premiums received from writing options which are exercised or are closed are added to or offset against the proceeds or amount paid on the transaction to determine the realized gain or loss. When an index option is exercised, the Fund is required to deliver an amount of cash determined by the excess of the exercise price of the option over the value of the index (in the case of a put) or the excess of the value of the index over the exercise price of the option (in the case of a call) at contract termination. If a put option on a security is exercised, the premium reduces the cost basis of the securities purchased by the Fund. The Fund, as a writer of an option, may have no control over whether the underlying securities or other assets may be sold (call) or purchased (put) and, as a result, bears the market risk of an unfavorable change in the price of the securities or other assets underlying the written option. The Fund may also bear the risk of not being able to enter into a closing transaction if a liquid secondary market does not exist.

I Purchased Options—Upon the purchase of a call or put option, the premium paid by the Fund is included in the Statement of Assets and Liabilities as an investment. The amount of the investment is subsequently marked-to-market to reflect the current market value of the option purchased, in accordance with the Fund’s policies on investment valuations discussed above. Premiums paid for purchasing options that expire are treated as realized losses. Premiums paid for purchasing options that are exercised or closed are added to the amounts paid or offset against the proceeds on the underlying investment transaction to determine the realized gain or loss. As the purchaser of an index option, the Fund has the right to receive a cash payment equal to any depreciation in the value of the index below the exercise price of the option (in the case of a put) or equal to any appreciation in the value of the index over the exercise price of the option (in the case of a call) as of the valuation date of the option. The risk associated with purchasing options is limited to the premium originally paid. Purchased options traded over-the-counter involve risk that the issuer or counterparty will fail to perform its contractual obligations.

J Segment Reporting—The Fund operates as a single reportable segment, an investment company whose investment objective(s) is included in Note 1. The Fund’s President acts as the Fund's Chief Operating Decision Maker (CODM), who is responsible for assessing the performance of the Fund's single segment and deciding how to allocate the segment’s resources. To perform this function, the CODM reviews the information in the Fund’s financial statements.

2 Distributions to Shareholders and Income Tax Information

Subject to its Managed Distribution Plan, the Fund makes monthly distributions from its cash available for distribution, which consists of the Fund’s dividends and interest income after payment of Fund expenses, net option premiums and net realized and unrealized gains on stock investments. The Fund intends to distribute all or substantially all of its net realized capital gains. Distributions are recorded on the ex-dividend date. Distributions to shareholders are determined in accordance with income tax regulations, which may differ from U.S. GAAP. As required by U.S. GAAP, only distributions in excess of tax basis earnings and profits are reported in the financial statements as a return of capital. Permanent differences between book and tax accounting relating to distributions are reclassified to paid-in capital. For tax purposes, distributions from short-term capital gains are considered to be from ordinary income. Distributions in any year may include a substantial return of capital component.

Notes to Financial Statements — continued

The tax character of distributions declared for the years ended December 31, 2025 and December 31, 2024 was as follows:

	Year Ended December 31,
	2025	2024
Long-term capital gains	$24,054,146	$30,372,308
Tax return of capital	$28,522,010	$20,750,130

During the year ended December 31, 2025, distributable earnings was increased by $2,311,813 and paid-in capital was decreased by $2,311,813 due to differences between book and tax accounting, primarily for net operating losses. These reclassifications had no effect on the net assets or net asset value per share of the Fund.

As of December 31, 2025, the components of distributable earnings (accumulated loss) on a tax basis were as follows:

Net unrealized appreciation	$ 316,389,937
Distributable earnings	$316,389,937

The cost and unrealized appreciation (depreciation) of investments, including open derivative contracts, of the Fund at December 31, 2025, as determined on a federal income tax basis, were as follows:

Aggregate cost	$336,549,673
Gross unrealized appreciation	$ 325,379,301
Gross unrealized depreciation	(8,989,364)
Net unrealized appreciation	$316,389,937

3 Investment Adviser Fee and Other Transactions with Affiliates

The investment adviser fee is earned by Eaton Vance Management (EVM), an indirect, wholly-owned subsidiary of Morgan Stanley, as compensation for investment advisory services rendered to the Fund. The fee is computed at an annual rate of 1.00% of the Fund’s average daily gross assets, as defined in the investment advisory agreement, and is payable monthly. For purposes of this calculation, gross assets represent net assets plus obligations attributable to investment leverage. During the year ended December 31, 2025, the Fund had no obligations attributable to investment leverage. For the year ended December 31, 2025, the investment adviser fee amounted to $6,454,939. The Fund may invest in a money market fund, the Institutional Class of the Morgan Stanley Institutional Liquidity Funds - Government Portfolio (the “Liquidity Fund”), an open-end management investment company managed by Morgan Stanley Investment Management Inc., a wholly-owned subsidiary of Morgan Stanley. The investment adviser fee paid by the Fund is reduced by an amount equal to its pro rata share of the advisory and administration fees paid by the Fund due to its investment in the Liquidity Fund. For the year ended December 31, 2025, the investment adviser fee paid was reduced by $7,714 relating to the Fund’s investment in the Liquidity Fund. EVM also serves as administrator of the Fund, but receives no compensation.

Trustees and officers of the Fund who are members of EVM’s organization receive remuneration for their services to the Fund out of the investment adviser fee. Trustees of the Fund who are not affiliated with EVM may elect to defer receipt of all or a percentage of their annual fees in accordance with the terms of the Trustees Deferred Compensation Plan. Certain officers and Trustees of the Fund are officers of EVM.

4 Purchases and Sales of Investments

Purchases and sales of investments, other than short-term obligations, aggregated $266,913,456 and $347,170,404, respectively, for the year ended December 31, 2025.

5 Common Shares of Beneficial Interest and Shelf Offering

The Fund may issue common shares pursuant to its dividend reinvestment plan. There were no common shares issued by the Fund for the years ended December 31, 2025 and December 31, 2024.

Table of Contents

Eaton Vance

Risk-Managed Diversified Equity Income Fund

December 31, 2025

Notes to Financial Statements — continued

In August 2012, the Board of Trustees initially approved a share repurchase program for the Fund. Pursuant to the reauthorization of the share repurchase program by the Board of Trustees in March 2019, the Fund is authorized to repurchase up to 10% of its common shares outstanding as of the last day of the prior calendar year at market prices when shares are trading at a discount to net asset value. The share repurchase program does not obligate the Fund to purchase a specific amount of shares. There were no repurchases of common shares by the Fund for the years ended December 31, 2025 and December 31, 2024.

In November 2021, the Fund filed an automatically effective shelf registration statement (the “2021 Registration Statement”) and a prospectus supplement, pursuant to the 2021 Registration Statement, relating to the offer and sale of up to an additional 9,600,000 common shares of the Fund under the Fund’s then current equity shelf offering program. As of November 2024, the offering of unsold shares pursuant to the 2021 Registration Statement has been terminated. During the years ended December 31, 2025 and December 31, 2024, there were no shares sold by the Fund pursuant to its then current shelf offering.

6 Financial Instruments

The Fund may trade in financial instruments with off-balance sheet risk in the normal course of its investing activities. These financial instruments may include written options and may involve, to a varying degree, elements of risk in excess of the amounts recognized for financial statement purposes. The notional or contractual amounts of these instruments represent the investment the Fund has in particular classes of financial instruments and do not necessarily represent the amounts potentially subject to risk. The measurement of the risks associated with these instruments is meaningful only when all related and offsetting transactions are considered. A summary of obligations under these financial instruments at December 31, 2025 is included in the Portfolio of Investments. At December 31, 2025, the Fund had sufficient cash and/or securities to cover commitments under these contracts.

The Fund is subject to equity price risk in the normal course of pursuing its investment objectives. The Fund pursues a “collared” options strategy which consists of buying S&P 500 index put options below the current value of the index and writing S&P 500 index call options above the current value of the index with the same expiration. The strategy uses the premium income from the written call options to buy an equal number of put options. In buying put options on an index, the Fund in effect, acquires protection against decline in the value of the applicable index below the exercise price in exchange for the option premium paid. In writing index call options, the Fund in effect, sells potential appreciation in the value of the applicable index above the exercise price. The Fund retains the risk of lost appreciation, minus the premium received, should the price of the underlying index rise above the exercise price. Under normal market conditions, the Fund’s use of option collars is expected to provide a more consistent level of market exposure and market protection.

The fair value of open derivative instruments (not considered to be hedging instruments for accounting disclosure purposes) and whose primary underlying risk exposure is equity price risk at December 31, 2025 was as follows:

	Fair Value
Derivative	Asset Derivative⁽¹⁾	Liability Derivative⁽²⁾
Purchased options	$ 1,321,669	$ —
Written options	—	(1,312,390)
Total	$1,321,669	$(1,312,390)

At December 31, 2025, the value of the Fund's investment in funds that may be deemed to be affiliated was $1,435,004, which represents 0.2% of the Fund's net assets. Transactions in such investments by the Fund for the year ended December 31, 2025 were as follows:

Name	Value, beginning of period	Purchases	Sales proceeds	Net realized gain (loss)	Change in unrealized appreciation (depreciation)	Value, end of period	Dividend income	Shares, end of period
Short-Term Investments
Liquidity Fund	$4,185,156	$148,025,833	$(150,775,985)	$ —	$ —	$1,435,004	$222,568	1,435,004

8 Fair Value Measurements

Under generally accepted accounting principles for fair value measurements, a three-tier hierarchy to prioritize the assumptions, referred to as inputs, is used in valuation techniques to measure fair value. The three-tier hierarchy of inputs is summarized in the three broad levels listed below.

•	Level 1 – quoted prices in active markets for identical investments
•	Level 2 – other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.)
•	Level 3 – significant unobservable inputs (including a fund's own assumptions in determining the fair value of investments)

In cases where the inputs used to measure fair value fall in different levels of the fair value hierarchy, the level disclosed is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

At December 31, 2025, the hierarchy of inputs used in valuing the Fund’s investments and open derivative instruments, which are carried at fair value, were as follows:

Asset Description	Level 1	Level 2	Level 3	Total
Common Stocks:
Communication Services	$ 97,387,961	$ —	$ —	$ 97,387,961

Report of Independent Registered Public Accounting Firm

To the Trustees and Shareholders of Eaton Vance Risk-Managed Diversified Equity Income Fund:

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying statement of assets and liabilities of Eaton Vance Risk-Managed Diversified Equity Income Fund (the "Fund"), including the portfolio of investments, as of December 31, 2025, the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, the financial highlights for each of the five years in the period then ended, and the related notes (collectively referred to as the “financial statements and financial highlights”). In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Fund as of December 31, 2025, and the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

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 December 31, 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.

We have served as the auditor of one or more Eaton Vance investment companies since 1959.

Dividend Reinvestment Plan

The Fund offers a dividend reinvestment plan (Plan) pursuant to which shareholders automatically have distributions reinvested in common shares (Shares) of the Fund unless they elect otherwise through their investment dealer. On the distribution payment date, if the NAV per Share is equal to or less than the market price per Share plus estimated brokerage commissions, then new Shares will be issued. The number of Shares shall be determined by the greater of the NAV per Share or 95% of the market price. Otherwise, Shares generally will be purchased on the open market by Equiniti Trust Company, LLC, the Plan agent (Agent). Distributions subject to income tax (if any) are taxable whether or not Shares are reinvested.

If your Shares are in the name of a brokerage firm, bank, or other nominee, you can ask the firm or nominee to participate in the Plan on your behalf. If the nominee does not offer the Plan, you will need to request that the Fund's transfer agent re-register your Shares in your name or you will not be able to participate.

The Agent’s service fee for handling distributions will be paid by the Fund. Plan participants will be charged their pro rata share of brokerage commissions on all open-market purchases.

Plan participants may withdraw from the Plan at any time by writing to the Agent at the address noted on the following page. If you withdraw, you will receive Shares in your name for all Shares credited to your account under the Plan. If a participant elects by written notice to the Agent to sell part or all of his or her Shares and remit the proceeds, the Agent is authorized to deduct a $5.00 fee plus brokerage commissions from the proceeds.

If you wish to participate in the Plan and your Shares are held in your own name, you may complete the form on the following page and deliver it to the Agent. Any inquiries regarding the Plan can be directed to the Agent at 1-866-439-6787.

Management and Organization

Fund Management. The Board of Trustees of the Fund (the “Board”) is responsible for the overall management and supervision of the affairs of the Fund. The Board members and officers of the Fund are listed below. Except as indicated, each individual has held the office shown or other offices in the same company for the last five years. Each Trustee holds office until the annual meeting for the year in which his or her term expires and until his or her successor is elected and qualified, subject to a prior death, resignation, retirement, disqualification or removal. Under the terms of the Fund’s current Trustee retirement policy, an Independent Trustee must retire and resign as a Trustee on the earlier of: (i) the first day of July following his or her 76th birthday; or (ii), with limited exception, December 31st of the 20th year in which he or she has served as a Trustee. However, if such retirement and resignation would cause the Fund to be out of compliance with Section 16 of the 1940 Act or any other regulations or guidance of the Securities and Exchange Commission, then such retirement and resignation will not become effective until such time as action has been taken for the Fund to be in compliance therewith. The “noninterested Trustees” consist of those Trustees who are not “interested persons” of the Fund, as that term is defined under the 1940 Act. The business address of each Board member and officer is One Post Office Square, Boston, Massachusetts 02109. As used below, “BMR” refers to Boston Management and Research, “EV” refers to EV LLC, “EVM” refers to Eaton Vance Management, “MSIM” refers to Morgan Stanley Investment Management Inc. and “EVD” refers to Eaton Vance Distributors, Inc. EV is the trustee of each of EVM and BMR. Each of EVM, BMR, EVD and EV are indirect, wholly owned subsidiaries of Morgan Stanley. Each officer affiliated with EVM may hold a position with other EVM affiliates that is comparable to his or her position with EVM listed below. Each Trustee oversees 123 funds in the Eaton Vance fund complex (including both funds and portfolios in a hub and spoke structure).

Potential Conflicts of Interest

As a diversified global financial services firm, Morgan Stanley, the parent company of the investment adviser, engages in a broad spectrum of activities, including financial advisory services, investment management activities, lending, commercial banking, sponsoring and managing private investment funds, engaging in broker-dealer transactions and principal securities, commodities and foreign exchange transactions, research publication and other activities. In the ordinary course of its business, Morgan Stanley is a full-service investment banking and financial services firm and therefore engages in activities where Morgan Stanley’s interests or the interests of its clients may conflict with the interests of a Fund or Portfolio, if applicable, (collectively for the purposes of this section, “Fund” or “Funds”). Morgan Stanley advises clients and sponsors, manages or advises other investment funds and investment programs, accounts and businesses (collectively, together with any new or successor funds, programs, accounts or businesses sponsored, managed, or advised by the investment adviser or one of its investment adviser affiliates, the “Affiliated Investment Accounts”) with a wide variety of investment objectives that in some instances may overlap or conflict with a Fund’s investment objectives and present conflicts of interest. In addition, Morgan Stanley, the investment adviser and/or the investment adviser’s investment adviser affiliates may also from time to time create new or successor Affiliated Investment Accounts that may compete with a Fund and present similar conflicts of interest. The discussion below enumerates certain actual, apparent and potential conflicts of interest. There is no assurance that conflicts of interest will be resolved in favor of Fund shareholders and, in fact, they may not be. The conflicts herein do not purport to be a complete list or explanation of the conflicts associated with the financial or other interests the investment adviser or its affiliates may have now or in the future. Conflicts of interest not described below may also exist. References to the investment adviser in this section include a Fund’s affiliated sub-adviser (if any) unless otherwise noted.

The discussions below with respect to actual, apparent and potential conflicts of interest may be applicable to or arise from the Affiliated Investment Accounts managed by the investment adviser’s investment adviser affiliates whether or not specifically identified.

Material Non-Public and Other Information. It is expected that confidential or material non-public information regarding an investment or potential investment opportunity may become available to the investment adviser. If such information becomes available, the investment adviser may be precluded (including by applicable law or internal policies or procedures) from pursuing an investment or disposition opportunity with respect to such investment or disposition opportunity including for an extended period of time. The investment adviser may also from time to time be subject to contractual “stand-still” obligations and/or confidentiality obligations that may restrict its ability to transact in certain investments on the Fund’s behalf. In addition, the investment adviser may be precluded from disclosing such information to an investment team, even in circumstances in which the information would be beneficial if disclosed. Therefore, the investment team may not be provided access to material non-public information in the possession of Morgan Stanley that might be relevant to an investment decision to be made on behalf of the Fund, and the investment team may initiate a transaction or sell an investment that, if such information had been known to it, may not have been undertaken. In addition, certain members of the investment team may be recused from certain investment-related discussions so that such members do not receive information that would limit their ability to perform functions of their employment with the investment adviser or its affiliates unrelated to that of the Fund. Furthermore, access to information held by certain parts of Morgan Stanley may be subject to third party confidentiality obligations and to information barriers established by Morgan Stanley designed to manage potential conflicts of interest and regulatory restrictions, including, without limitation, joint transaction restrictions pursuant to the 1940 Act. Accordingly, the investment adviser’s ability to source investments from, or invest alongside, other business units within Morgan Stanley may be limited and there can be no assurance that the investment adviser will be able to source any investments from any one or more parts of the Morgan Stanley network.

The investment adviser may restrict its investment decisions and activities on behalf of the Fund in various circumstances, including because of applicable regulatory requirements or information held by the investment adviser, the investment adviser’s investment adviser affiliates or Morgan Stanley. The investment adviser might not engage in transactions or other activities for, or enforce certain rights in favor of, the Fund due to Morgan Stanley’s activities outside the Fund. Furthermore, Morgan Stanley could have an interest that is different from, and potentially adverse to, that of the Fund, which may impede the Fund from participating in certain opportunities. In instances where trading of an investment is restricted, the investment adviser may not be able to purchase or sell such investment on behalf of the Fund including for an extended period of time, resulting in the Fund’s inability to participate in certain desirable transactions. This inability to buy or sell an investment could have an adverse effect on the Fund’s portfolio due to, among other things, changes in an investment’s value during the period its trading is restricted.

Morgan Stanley has established certain information barriers and other policies designed to address the sharing of information between different businesses within Morgan Stanley. As a result of information barriers, the investment adviser, in certain instances, will not have access, or will have limited access, to certain information and personnel in other areas of Morgan Stanley and, in such instances, will not manage the Fund with the benefit of the information held by such other areas. Morgan Stanley, due to its access to and knowledge of funds, markets and securities based on its various businesses, may make decisions based on information or take (or refrain from taking) actions with respect to interests in investments of the kind held (directly or indirectly) by the Fund in a manner that may be adverse to the Fund, and will not have any obligation or other duty to share information with the investment adviser.

In other instances, Morgan Stanley personnel, including personnel of the investment adviser, will have access to information and personnel of its affiliates. For example, the investment adviser may, in certain instances, share information with its affiliates regarding due diligence of companies and other investment-related due diligence. The investment adviser may face conflicts of interest in determining whether to engage in the sharing of information with its affiliates. Information sharing may limit or restrict the ability of the investment adviser to engage in or otherwise effect transactions on behalf of the Fund (including purchasing or selling securities that the investment adviser may otherwise have purchased or sold for the Fund in the absence of the sharing of information). Also, it may adversely affect the Fund's investments, ability to invest in, or divest from, a company or engage in transactions or otherwise disadvantage the Fund. In managing conflicts of interest that arise because of the foregoing, the investment adviser generally will be subject to fiduciary requirements. The investment adviser may also implement internal information barriers or ethical walls or other internal information sharing protocols, and the conflicts described herein with respect to information barriers and otherwise with respect to Morgan Stanley and the investment adviser will also apply

internally within the investment adviser. As a result, the Fund may not be permitted to transact in (e.g., dispose of a security in whole or in part) during periods when it otherwise would have been desirable and able to do so, which could adversely affect the Fund. Other investors in the security that are not subject to such restrictions may be able to transact in the security during such periods. There may also be circumstances in which, as a result of information held by certain portfolio management teams in the investment adviser, the investment adviser limits an activity or transaction for the Fund, including if the Fund is managed by a portfolio management team other than the team holding such information.

Morgan Stanley and its personnel will not be under any obligation or other duty to share certain information with the investment adviser or personnel involved in decision-making for Affiliated Investment Accounts (including the Fund), as applicable, and the investment adviser may make investment decisions for the Fund that differ from those the investment adviser would have made if Morgan Stanley, or other parts, of the investment adviser had provided such information, and the Fund be disadvantaged as a result thereof. Additionally, different portfolio management teams within the investment adviser may make decisions based on information or take (or refrain from taking) actions with respect to Affiliated Investment Accounts they advise in a manner different than or adverse to the Fund.

Investments by Morgan Stanley and its Affiliated Investment Accounts. In serving in multiple capacities to Affiliated Investment Accounts, Morgan Stanley, including the investment adviser and its investment teams, may have obligations to other clients or investors in Affiliated Investment Accounts, the fulfillment of which may not be in the best interests of the Fund or its shareholders. An investment team may have obligations to Affiliated Investment Accounts managed by both the investment adviser and one or more of the investment adviser’s investment adviser affiliates. The Fund’s investment objectives may overlap with the investment objectives of certain Affiliated Investment Accounts. As a result, the members of an investment team may face conflicts in the allocation of investment opportunities among the Fund and other investment funds, programs, accounts and businesses advised by or affiliated with the investment adviser or its investment adviser affiliates. Certain Affiliated Investment Accounts may provide for higher management or incentive fees or greater expense reimbursements or overhead allocations, all of which may contribute to this conflict of interest and create an incentive for the investment adviser to favor such other accounts.

Morgan Stanley currently invests and plans to continue to invest on its own behalf and on behalf of its Affiliated Investment Accounts in a wide variety of investment opportunities globally. Morgan Stanley and its Affiliated Investment Accounts, to the extent consistent with applicable law and policies and procedures, will be permitted to invest in investment opportunities without making such opportunities available to the Fund. Subject to the foregoing, Morgan Stanley may offer investments that fall into the investment objectives of an Affiliated Investment Account to such account or make such investment on its own behalf, even though such investment also falls within the Fund’s investment objectives. The Fund may invest in opportunities that Morgan Stanley and/or one or more Affiliated Investment Accounts has declined, and vice versa. All of the foregoing may reduce the number of investment opportunities available to the Fund and may create conflicts of interest in allocating investment opportunities. Investors should note that the conflicts inherent in making such allocation decisions may not always be resolved to the Fund’s advantage. There can be no assurance that the Fund will have an opportunity to participate in certain opportunities that fall within their investment objectives. The interests of Morgan Stanley in an investment or a company may present certain conflicts of interest with respect to an investment by the Fund in the same investment or the Fund's participation in a transaction with such company.

To the extent the investment adviser utilizes quantitative models or risk management or optimization investment techniques, the decision on when to initiate a purchase or sale transaction may differ, and be done for different reasons, than the investment adviser or its affiliates take on Affiliated Investment Accounts on the same securities when not utilizing such techniques. This could create conflicts of interest, and it is possible that one or more accounts managed by the investment adviser will achieve investment results that are substantially more or less favorable than those results achieved by the Fund.

To seek to reduce potential conflicts of interest and to attempt to allocate such investment opportunities in a fair and equitable manner, the investment adviser has implemented allocation policies and procedures. These policies and procedures are intended to give all clients of the investment adviser, including the Fund, fair access to investment opportunities consistent with the requirements of organizational documents, investment strategies, applicable laws and regulations, and the fiduciary duties of the investment adviser. Each client of the investment adviser that is subject to the allocation policies and procedures, including the Fund, is assigned an investment team and portfolio manager(s) by the investment adviser. The investment team and portfolio managers review investment opportunities and will decide with respect to the allocation of each opportunity considering various factors and in accordance with the allocation policies and procedures. The allocation policies and procedures are subject to change. Investors should note that the conflicts inherent in making such allocation decisions may not always be resolved to the advantage of the Fund.

It is possible that Morgan Stanley or an Affiliated Investment Account, including another Morgan Stanley Fund, will invest in or advise (in the case of Morgan Stanley) a company that is or becomes a competitor of a company of which the Fund holds an investment. Such investment could create a conflict between the Fund, on the one hand, and Morgan Stanley or the Affiliated Investment Account, on the other hand. In such a situation, Morgan Stanley may also have a conflict in the allocation of its own resources to the portfolio investment. Furthermore, certain Affiliated Investment Accounts will be focused primarily on investing in other funds which may have strategies that overlap and/or directly conflict and compete with the Fund.

In addition, certain investment professionals who are involved in the Fund’s activities remain responsible for the investment activities of other Affiliated Investment Accounts managed by the investment adviser and its affiliates, and they will devote time to the management of such investments and other newly created Affiliated Investment Accounts (whether in the form of funds, separate accounts or other vehicles), as well as their own investments. In

addition, in connection with the management of investments for other Affiliated Investment Accounts, members of Morgan Stanley and its affiliates may serve on the boards of directors of or advise companies which may compete with the Fund’s portfolio investments. Moreover, these Affiliated Investment Accounts managed by Morgan Stanley and its affiliates may pursue investment opportunities that may also be suitable for the Fund.

It should be noted that Morgan Stanley may, directly or indirectly, make large investments in certain of its Affiliated Investment Accounts, and accordingly Morgan Stanley’s investment in the Fund may not be a determining factor in the outcome of any of the foregoing conflicts. Nothing herein restricts or in any way limits the activities of Morgan Stanley, including its ability to buy or sell interests in, or provide financing to, equity and/or debt instruments, funds or portfolio companies, for its own accounts or for the accounts of Affiliated Investment Accounts or other investment funds or clients in accordance with applicable law.

Different clients of the investment adviser and its affiliates, including the Fund, may invest in (1) different classes of securities of the same issuer (including, without limitation, different parts of an issuer's capital structure), depending on the respective clients’ investment objectives and policies and/or (2) the same class of securities of the same issuer while seeking different investment objectives or executing different investment strategies (such as long-term v. short-term investment horizons), and the investment adviser may face conflicts with respect to the interests involved. As a result, the investment adviser and its affiliates, at times, will seek to satisfy fiduciary obligations to certain clients owning one / the same class of securities of a particular issuer by pursuing or enforcing rights on behalf of those clients with respect to such (class of) securities, and those activities may have an adverse effect on another client which owns a different class of securities of such issuer. For example, if one client holds debt securities of an issuer and another client holds equity securities of the same issuer, if the issuer experiences financial or operational challenges, the investment adviser and its affiliates may seek a liquidation of the issuer on behalf of the client that holds the debt securities, whereas the client holding the equity securities may benefit from a reorganization of the issuer. Thus, in such situations, the actions taken by the investment adviser or its affiliates on behalf of one client can negatively impact securities held by another client. Alternatively, for example, if a client owns a security while seeking short-term capital appreciation that investment adviser may vote proxies or engage with the issuer (as applicable) in pursuit of that goal – which could negatively impact clients who hold the same security but are seeking long-term capital appreciation. These conflicts also exist as between the investment adviser’s clients, including the Fund, and the Affiliated Investment Accounts managed by the investment adviser’s investment adviser affiliates.

In addition, in certain circumstances, the investment adviser restricts, limits or reduces the amount of the Fund’s investment, or restricts the type of governance or voting rights it acquires or exercises, where the Fund (potentially together with Morgan Stanley) exceeds a certain ownership interest, or possesses certain degrees of voting or control or has other interests.

The investment adviser and its affiliates may give advice and recommend securities to other clients which may differ from advice given to, or securities recommended or bought for, the Fund even though such other clients’ investment objectives may be similar to those of the Fund and the investment adviser may make decisions for the Fund that may be more beneficial to one type of shareholder than another.

The investment adviser and its affiliates manage long and short portfolios. The simultaneous management of long and short portfolios creates conflicts of interest in portfolio management and trading in that opposite directional positions may be taken in client accounts, including client accounts managed by the same investment team, and creates risks such as: (i) the risk that short sale activity could adversely affect the market value of long positions in one or more portfolios (and vice versa) and (ii) the risks associated with the trading desk receiving opposing orders in the same security simultaneously. The investment adviser and its affiliates have adopted policies and procedures that are reasonably designed to mitigate these conflicts. In certain circumstances, the investment adviser invests on behalf of itself in securities and other instruments that would be appropriate for, held by, or may fall within the investment guidelines of its clients, including the Fund. At times, the investment adviser may give advice or take action for its own accounts that differs from, conflicts with, or is adverse to advice given or action taken for any client.

From time to time, conflicts also arise due to the fact that certain securities or instruments may be held in some client accounts, including the Fund, but not in others, or that client accounts may have different amounts of holdings in certain securities or instruments. In addition, due to differences in the investment strategies or restrictions among client accounts, the investment adviser may take action with respect to one account that differs from the action taken with respect to another account. In some cases, a client account may compensate the investment adviser based on the performance of the securities held by that account or pay a higher overall fee rate. The existence of such a performance based fee or higher fee rates may create additional conflicts of interest for the investment adviser in the allocation of management time, resources and investment opportunities. The investment adviser has adopted several policies and procedures designed to address these potential conflicts including a code of ethics and policies that govern the investment adviser’s trading practices, including, among other things, the aggregation and allocation of trades among clients, brokerage allocations, cross trades and best execution.

In addition, at times an investment team will give advice or take action with respect to the investments of one or more clients that is not given or taken with respect to other clients with similar investment programs, objectives, and strategies. Accordingly, clients with similar strategies will not always hold the same securities or instruments or achieve the same performance. The investment adviser’s investment teams also advise clients with conflicting programs, objectives or strategies. These conflicts also exist as between the investment adviser’s clients, including the Fund, and the Affiliated Investment Accounts managed by the investment adviser’s investment adviser affiliates.

From time to time, the investment adviser or its affiliates may provide opportunities to Affiliated Investment Accounts (including potentially the Fund) or other clients to make investments in companies (such as in equity, debt or other securities issued by companies) or to engage in transactions involving companies (such as refinancing, restructuring or other transactions) in which certain Affiliated Investment Accounts (including potentially the Fund) or other clients have already invested. These investments can create conflicts of interest, including those associated with the assets of the Fund potentially providing value to, or otherwise supporting the investments of, other Affiliated Investment Accounts or other clients and potentially diluting or otherwise adversely affecting the Fund previously invested in the company.

Morgan Stanley and its affiliates maintain separate trading desks that operate independently of each other and do not share information with the investment adviser. The Morgan Stanley and affiliate trading desks may compete against the investment adviser trading desks when implementing buy and sell transactions, possibly causing certain Affiliated Investment Accounts to pay more or receive less for a security than other Affiliated Investment Accounts.

Investments by Separate Investment Departments. For the investment adviser and certain of its investment adviser affiliates, the entities and individuals that provide investment-related services can differ by client, investment function, or business line (each, an “Investment Department” and collectively, the “Investment Departments”). Nonetheless, Investment Departments (with certain exceptions) can engage in discussions and share information and resources with another Investment Department (or a team within the other Investment Department) regarding investment-related matters. The sharing of information and resources between the Investment Departments is designed to further increase the knowledge and effectiveness of each Investment Department. However, an investment team’s decisions as to the use of shared research and participation in discussions with another Investment Department could adversely impact a client. Certain investment teams within one Investment Department could make investment decisions and execute trades together with investment teams within other Investment Departments. Other investment teams make investment decisions and execute trades independently. This could cause the quality and price of execution, and the performance of investments and accounts, to vary. Internal policies and procedures set forth the guidelines under which securities and securities trades can be crossed, aggregated, and coordinated between accounts serviced by different Investment Departments. Internal policies and procedures take into consideration a variety of factors, including the primary market in which such security trades. If a security or securities trade is ineligible for crossing, aggregation, or other coordinated trading, then each Investment Department will execute such trades independently of the other.

Payments to Broker-Dealers and Other Financial Intermediaries. The investment adviser, Eaton Vance Distributors, Inc. (the “Distributor”) and/or their affiliates may pay compensation, out of their own funds and not as an expense of the Fund, to certain Financial Intermediaries (which may include affiliates of the investment adviser and the Distributor), including recordkeepers and administrators of various deferred compensation plans, in connection with the sale, distribution, marketing and retention of shares of the Fund and/or shareholder servicing. For example, the investment adviser or the Distributor may pay additional compensation to a Financial Intermediary for, among other things, promoting the sale and distribution of Fund shares, providing access to various programs, mutual fund platforms or preferred or recommended mutual fund lists that may be offered by a Financial Intermediary, granting the Distributor access to a Financial Intermediary’s financial advisors and consultants, providing assistance in the ongoing education and training of a Financial Intermediary’s financial personnel, furnishing marketing support, maintaining share balances and/or for sub-accounting, recordkeeping, administrative, shareholder or transaction processing services. Such payments are in addition to any distribution fees, shareholder servicing fees and/or transfer agency fees that may be payable by the Fund. The additional payments may be based on various factors, including level of sales (based on gross or net sales or some specified minimum sales or some other similar criteria related to sales of the Fund and/or some or all other Morgan Stanley Funds), amount of assets invested by the Financial Intermediary’s customers (which could include current or aged assets of the Fund and/or some or all other Morgan Stanley Funds), the Fund’s advisory fee, some other agreed upon amount or other measures as determined from time to time by the investment adviser and/or the Distributor. The amount of these payments may be different for different Financial Intermediaries. In certain cases, payments to broker-dealers and other Financial Intermediaries may be shared by and among the investment adviser, the Distributor and their affiliates.

The prospect of receiving, or the receipt of, additional compensation, as described above, by Financial Intermediaries may provide such Financial Intermediaries and their financial advisors and other salespersons with an incentive to favor sales of shares of the Fund over other investment options with respect to which these Financial Intermediaries do not receive additional compensation (or receives lower levels of additional compensation). These payment arrangements, however, will not change the price that an investor pays for shares of the Fund or the amount that the Fund receives to invest on behalf of an investor. Investors may wish to take such payment arrangements into account when considering and evaluating any recommendations relating to Fund shares and should review carefully any disclosures provided by Financial Intermediaries as to their compensation.

The additional compensation received by a given Financial Intermediary from the investment adviser and/or the Distributor may vary from the additional compensation received by the Financial Intermediary in respect of an Affiliated Investment Account managed by an affiliate of the investment adviser or principally underwritten by an affiliate of the Distributor. In such circumstances, differences in the prospect of receiving, or the receipt of, additional compensation, as described above, by Financial Intermediaries may provide such Financial Intermediaries and their financial advisors and other salespersons with an incentive to favor sales of shares of one Affiliated Investment Account over other investment options with respect to which these Financial Intermediaries do not receive additional compensation (or receives lower levels of additional compensation).

Morgan Stanley Trading and Principal Investing Activities. Notwithstanding anything to the contrary herein, Morgan Stanley will generally conduct its sales and trading businesses, publish research and analysis, and render investment advice without regard for the Fund’s holdings, although these activities could have an adverse impact on the value of one or more of the Fund’s investments, or could cause Morgan Stanley to have an interest in one or more portfolio investments that is different from and potentially adverse to that of the Fund. Furthermore, from time to time, the investment adviser or its affiliates may

invest “seed” capital in a Fund, typically to enable such Fund to commence investment operations and/or achieve sufficient scale, as further described below. The investment adviser and its affiliates may hedge such seed capital exposure by investing in derivatives or other instruments expected to produce offsetting exposure. Such hedging transactions, if any, would occur outside of such Fund.

Morgan Stanley’s sales and trading, financing and principal investing businesses (whether or not specifically identified as such, and including Morgan Stanley’s trading and principal investing businesses) will not be required to offer any investment opportunities to the Fund. These businesses may encompass, among other things, principal trading activities as well as principal investing.

Morgan Stanley’s sales and trading, financing and principal investing businesses have acquired or invested in, and in the future may acquire or invest in, minority and/or majority control positions in equity or debt instruments of diverse public and/or private companies. Such activities may put Morgan Stanley in a position to exercise contractual, voting or creditor rights, or management or other control with respect to securities or loans of portfolio investments or other issuers, and in these instances Morgan Stanley may, in its discretion and subject to applicable law, act to protect its own interests or interests of clients, and not the Fund’s interests.

Subject to the limitations of applicable law, the Fund may purchase from or sell assets to, or make investments in, companies in which Morgan Stanley has or may acquire an interest, including as an owner, creditor or counterparty.

Morgan Stanley’s Investment Banking and Other Commercial Activities. Morgan Stanley advises clients on a variety of mergers, acquisitions, restructuring, bankruptcy and financing transactions. Morgan Stanley may act as an advisor to clients, including other investment funds that may compete with the Fund and with respect to investments that the Fund may hold. Morgan Stanley may give advice and take action with respect to any of its clients or proprietary accounts that may differ from the advice given, or may involve an action of a different timing or nature than the action taken, by the Fund. Morgan Stanley may give advice and provide recommendations to persons competing with the Fund and/or any of the Fund’s investments that are contrary to the Fund’s best interests and/or the best interests of any of its investments.

Morgan Stanley could be engaged in financial advising, whether on the buy-side or sell-side, or in financing or lending assignments that could result in Morgan Stanley’s determining in its discretion or being required to act exclusively on behalf of one or more third parties, which could limit the Fund’s ability to transact with respect to one or more existing or potential investments. Morgan Stanley may have relationships with third-party funds, companies or investors who may have invested in or may look to invest in portfolio companies, and there could be conflicts between the Fund’s best interests, on the one hand, and the interests of a Morgan Stanley client or counterparty, on the other hand.

To the extent that Morgan Stanley advises companies in financial restructurings outside of, prior to or after filing for protection under Chapter 11 of the U.S. Bankruptcy Code or similar laws in other jurisdictions, the investment adviser’s flexibility in making investments in such restructurings on the Fund’s behalf, or participating on steering committees and other committees in connection with existing investments, may be limited.

Morgan Stanley could provide investment banking services to competitors of portfolio companies, as well as to private equity and/or private credit funds; such activities may present Morgan Stanley with a conflict of interest vis-a-vis the Fund’s investment and may also result in a conflict in respect of the allocation of investment banking resources to portfolio companies.

To the extent permitted by applicable law, Morgan Stanley may provide a broad range of financial services to companies in which the Fund invests, including strategic and financial advisory services, interim acquisition financing and other lending and underwriting or placement of securities, and Morgan Stanley generally will be paid fees (that may include warrants or other securities) for such services. Morgan Stanley will not share any of the foregoing interest, fees and other compensation received by it (including, for the avoidance of doubt, amounts received by the investment adviser) with the Fund, and any advisory fees payable will not be reduced thereby.

Morgan Stanley may be engaged to act as a financial advisor to a company in connection with the sale of such company, or subsidiaries or divisions thereof, may represent potential buyers of businesses through its mergers and acquisition activities and may provide lending and other related financing services in connection with such transactions. Morgan Stanley’s compensation for such activities is usually based upon realized consideration and is usually contingent, in substantial part, upon the closing of the transaction. Under these circumstances, the Fund may be precluded from participating in a transaction with or relating to the company being sold or participating in any financing activity related to merger or acquisition.

The involvement or presence of Morgan Stanley in the investment banking and other commercial activities described above (or the financial markets more broadly) may restrict or otherwise limit investment opportunities that may otherwise be available to the Fund. For example, issuers may hire and compensate Morgan Stanley to provide underwriting, financial advisory, placement agency, brokerage services or other services and, because of limitations imposed by applicable law and regulation, the Fund may be prohibited from buying or selling securities issued by those issuers or participating in related transactions or otherwise limited in its ability to engage in such investments.

In addition, in situations where the investment adviser is required to aggregate its positions with those of other Morgan Stanley business units for position limit calculations, the investment adviser may have to refrain from making investments due to the positions held by other Morgan Stanley business units or their clients. There may be other situations where the investment adviser refrains from making an investment or refrains from taking certain actions related to the management of such investment due to, among other reasons, additional disclosure obligations, regulatory requirements, policies, and reputational risk, or the investment adviser may limit purchases or sales of securities in respect of which Morgan Stanley is engaged in an underwriting or other distribution capacity.

Morgan Stanley’s Marketing Activities. Morgan Stanley is engaged in the business of underwriting, syndicating, brokering, administering, servicing, arranging and advising on the distribution of a wide variety of securities and other investments in which the Fund may invest. Subject to the restrictions of the 1940 Act, including Sections 10(f) and 17(e) thereof, the Fund may invest in transactions in which Morgan Stanley acts as underwriter, placement agent, syndicator, broker, administrative agent, servicer, advisor, arranger or structuring agent and receives fees or other compensation from the sponsors of such products or securities. Any fees earned by Morgan Stanley in such capacity will not be shared with the investment adviser or the Fund. Certain conflicts of interest, in addition to the receipt of fees or other compensation, would be inherent in these transactions. Moreover, the interests of one of Morgan Stanley’s clients with respect to an issuer of securities in which the Fund has an investment may be adverse to the investment adviser’s or the Fund’s best interests. In conducting the foregoing activities, Morgan Stanley will be acting for its other clients and will have no obligation to act in the investment adviser’s or the Fund’s best interests. Due to the restrictions of the 1940 Act, the Fund may be restricted from participating in certain transactions in which Morgan Stanley acts as underwriter, placement agent, syndicator, broker, administrative agent, servicer, advisor, arranger or structuring agent, including transactions that would otherwise be beneficial to the Fund.

Client Relationships. Morgan Stanley has existing and potential relationships with a significant number of corporations, institutions and individuals. In providing services to its clients, Morgan Stanley may face conflicts of interest with respect to activities recommended to or performed for such clients, on the one hand, and the Fund, its shareholders or the entities in which the Fund invests, on the other hand. In addition, these client relationships may present conflicts of interest in determining whether to offer certain investment opportunities to the Fund.

In acting as principal or in providing advisory and other services to its other clients, Morgan Stanley may engage in or recommend activities with respect to a particular matter that conflict with or are different from activities engaged in or recommended by the investment adviser on the Fund’s behalf.

Principal Investments. There may be situations in which the Fund’s interests may conflict with the interests of one or more general accounts of Morgan Stanley and its affiliates or accounts managed by Morgan Stanley or its affiliates. This may occur because these accounts hold public and private debt and equity securities of many issuers which may be or become portfolio companies, or from whom portfolio companies may be acquired.

Transactions with Portfolio Companies of Affiliated Investment Accounts. The companies in which the Fund may invest may be counterparties to or participants in agreements, transactions or other arrangements with portfolio companies or other entities of portfolio investments of Affiliated Investment Accounts (for example, a company in which the Fund invests may retain a company in which an Affiliated Investment Account invests to provide services or may acquire an asset from such company or vice versa). Certain of these agreements, transactions and arrangements involve fees, servicing payments, rebates and/or other benefits to Morgan Stanley or its affiliates. For example, portfolio entities may, including at the encouragement of Morgan Stanley, enter into agreements regarding group procurement and/or vendor discounts. Morgan Stanley and its affiliates may also participate in these agreements and may realize better pricing or discounts as a result of the participation of portfolio entities. To the extent permitted by applicable law, certain of these agreements may provide for commissions or similar payments and/or discounts or rebates to be paid to a portfolio entity of an Affiliated Investment Account, and such payments or discounts or rebates may also be made directly to Morgan Stanley or its affiliates. Under these arrangements, a particular portfolio company or other entity may benefit to a greater degree than the other participants, and the Morgan Stanley Funds, investment vehicles and accounts (which may or may not include the Fund) that own an interest in such entity will receive a greater relative benefit from the arrangements than the Morgan Stanley Funds, investment vehicles or accounts that do not own an interest therein. Fees and compensation received by portfolio companies of Affiliated Investment Accounts in relation to the foregoing will not be shared with a Fund or offset advisory fees payable.

Investments in Portfolio Investments of Other Funds. To the extent permitted by applicable law, when the Fund invests in certain companies or other entities, other funds affiliated with the investment adviser may have made or may be making an investment in such companies or other entities. Other funds that have been or may be managed by the investment adviser may invest in the companies or other entities in which the Fund has made an investment. Under such circumstances, the Fund and such other funds may have conflicts of interest (e.g., over the terms, exit strategies and related matters, including the exercise of remedies of their respective investments). If the interests held by the Fund are different from (or take priority over) those held by such other funds, the investment adviser may be required to make a selection at the time of conflicts between the interests held by such other funds and the interests held by the Fund.

Investments in Morgan Stanley Funds and Other Funds. To the extent permitted by applicable law, the Fund may invest in a fund affiliated with the investment adviser or its affiliates or a fund advised by the investment adviser or its affiliates. In connection with any such investments, an investing Fund, to the extent permitted by the 1940 Act, will pay all advisory, administrative and/or Rule 12b-1 fees applicable to the investment. Investments by a Fund in a fund affiliated with the investment adviser or its affiliates or a fund advised by the investment adviser or its affiliates present potential conflicts of interest, including potential incentives to invest in smaller or newer funds to increase asset levels or provide greater viability. The investment adviser voluntarily waives advisory fees of a Fund associated with investments by the Fund in a fund advised by the investment adviser or its affiliates which will reduce, but will not eliminate, these types of conflicts.

Potential Conflicts of Interest — continued

The Affiliated Investment Accounts (including the Funds) may, individually or in the aggregate, own a substantial percentage of a Fund. Further, the Adviser, its affiliates, or another entity (i.e., a seed investor) may invest in the Funds at or near the establishment of such Funds, which may facilitate the Funds achieving a specified size or scale. The Adviser and/or its affiliates may make payments to an investor that contributes seed capital to a Fund. Such payments may continue for a specified period of time and/or until a specified dollar amount is reached, and will be made from the assets of the Adviser and/or such affiliates (and not the applicable Fund). Seed investors may contribute all or a majority of the assets in a Fund. There is a risk that such seed investors may redeem their investments in the Fund, particularly after payments from the Adviser and/or its affiliates have ceased. Such redemptions could negatively impact a Fund’s liquidity, expenses and market price of its shares, as applicable.

Allocation of Expenses. Expenses may be incurred that are attributable to the Fund and one or more other Affiliated Investment Accounts (including in connection with issuers in which the Fund and such other Affiliated Investment Accounts have overlapping investments). The allocation of such expenses among such entities raises potential conflicts of interest. The investment adviser and its affiliates intend to allocate such common expenses among the Fund and any such other Affiliated Investment Accounts on a pro rata basis or in such other manner as the investment adviser deems to be fair and equitable or in such other manner as may be required by applicable law.

Temporary Investments. To more efficiently invest short-term cash balances held by the Fund, the investment adviser may invest such balances on an overnight “sweep” basis in shares of one or more money market funds or other short-term vehicles. It is anticipated that the investment adviser to these money market funds or other short-term vehicles may be the investment adviser (or an affiliate) to the extent permitted by applicable law, including Rule 12d1-1 under the 1940 Act. In such a case, the affiliated investment adviser may receive asset-based fees in respect of the Fund’s investment (which will reduce the net return realized by the Fund).

Transactions with Affiliates. The investment adviser and any investment sub-adviser might purchase securities from underwriters or placement agents in which a Morgan Stanley affiliate is a member of a syndicate or selling group, as a result of which an affiliate might benefit from the purchase through receipt of a fee or otherwise. Neither the investment adviser nor any investment sub-adviser will purchase securities on behalf of the Fund from an affiliate that is acting as a manager of a syndicate or selling group. Purchases by the investment adviser on behalf of the Fund from an affiliate acting as a placement agent must meet the requirements of applicable law. Furthermore, Morgan Stanley may face conflicts of interest when a Fund uses service providers affiliated with Morgan Stanley because Morgan Stanley receives greater overall fees when they are used.

Affiliated Indexes. Affiliates of the investment adviser develop, own and operate indexes (“Indexes”), and may continue to do so in the future, based on investment and trading strategies and concepts developed by the investment adviser or its affiliates (“Adviser Strategies”). Some of the Funds seek to track the performance of the Indexes. The investment adviser manages Accounts which track the same Indexes used by the Funds or which are based on the same, or substantially similar, Adviser Strategies that are used in the operation of the Indexes and the Funds. The operation of the Indexes, the Funds and the Accounts in this manner gives rise to potential conflicts of interest. For example, Accounts that track the same Indexes used by the Funds may engage in purchases and sales of securities prior to when the Index and the Funds engage in similar transactions because such Accounts may be managed and rebalanced on an ongoing basis, whereas the Funds’ portfolios are only rebalanced on a periodic or other basis subsequent to the rebalancing of the Index.

The investment adviser has adopted policies and procedures that are designed to address potential conflicts that arise in connection with the operation of the Indexes, the Funds and the Accounts. The investment adviser has established certain information barriers and other policies designed to address the sharing of information between different businesses within the investment adviser, including with respect to personnel responsible for constructing and maintaining the Indexes and those involved in decision-making for the Funds.

Valuation of the Fund’s Investments. The investment adviser performs certain valuation services related to securities and other assets held by the Fund and performs such services in accordance with its valuation policies. The investment adviser will face a conflict with respect to valuation of the Fund’s investments generally because of the effect of such valuations on the investment adviser’s fees and other compensation and performance of the Fund.

Proxy Voting by the Adviser. The investment adviser has implemented processes designed to prevent conflicts of interest from influencing proxy voting decisions that it makes on behalf of advisory clients, including the Funds, and to help ensure that such decisions are made in accordance with its fiduciary obligations to its clients. Notwithstanding such proxy voting processes, proxy voting decisions made by the investment adviser in respect of securities held by the Fund may benefit the interests of Morgan Stanley and/or accounts other than the Fund. Further, the investment adviser may make different proxy voting decisions in respect of the same security held by clients with different investment objectives or strategies.

Potential Conflict of Interest Related to Use of Sub-Adviser(s). To the extent the Fund’s investment adviser engages affiliated and/or unaffiliated sub-advisers, the investment adviser generally expects to compensate the sub-adviser out of the advisory fee it receives from the Fund, which creates an incentive for the investment adviser to select sub-adviser(s) with lower fee rates or to select affiliated sub-adviser(s). In addition, a sub-adviser may have interests and relationships that create actual or potential conflicts of interest related to their management of Fund assets allocated to or managed by the sub-adviser. These conflicts may be similar to or different from the conflicts described herein related to Morgan Stanley and its investment advisory affiliates. For additional information about potential conflicts of interest for each sub-adviser(s) can be found in the relevant sub-adviser’s Form ADV. A copy of Part 1 and Part 2 of a sub-adviser’s Form ADV is available on the SEC’s website (www.adviserinfo.sec.gov).

Electronic Communication Networks and Alternative Trading Systems. The investment adviser’s affiliate(s) have ownership interests in and/or board seats on electronic communication networks (“ECNs”) or other alternative trading systems (“ATSs”). In certain instances the investment adviser’s affiliate(s) could be deemed to control one or more of such ECNs or ATSs based on the level of such ownership interests and whether such affiliates are represented on the

board of such ECNs or ATSs. Consistent with its fiduciary obligation to seek best execution, the Adviser may, from time to time, directly or indirectly, effect client trades through ECNs or other ATSs in which the Firm’s affiliates have or could acquire an interest or board seat. These affiliates might receive an indirect economic benefit based upon their ownership in the ECNs or other ATSs. The investment adviser will, directly or indirectly, execute through an ECN or other ATSs in which an affiliate has an interest only in situations where the Firm or the broker dealer through whom it is accessing the ECN or ATS reasonably believes such transaction will be in the best interest of its clients and the requirements of applicable law have been satisfied.

General Process for Potential Conflicts. All of the transactions described above involve the potential for conflicts of interest between the investment adviser, related persons of the investment adviser and/or their clients. The Advisers Act, the 1940 Act and ERISA impose certain requirements designed to decrease the possibility of conflicts of interest between an investment adviser and its clients. In some cases, transactions may be permitted subject to fulfillment of certain conditions. Certain other transactions may be prohibited. In addition, the investment adviser has instituted policies and procedures designed to prevent conflicts of interest from arising and, when they do arise, to ensure that it effects transactions for clients in a manner that is consistent with its fiduciary duty to its clients and in accordance with applicable law. The investment adviser seeks to ensure that potential or actual conflicts of interest are appropriately resolved taking into consideration the overriding best interests of the client.

IMPORTANT NOTICES

Delivery of Shareholder Documents. The Securities and Exchange Commission (SEC) permits funds to deliver only one copy of shareholder documents, including prospectuses, proxy statements and shareholder reports, to fund investors with multiple accounts at the same residential or post office box address. This practice is often called “householding” and it helps eliminate duplicate mailings to shareholders. Equiniti Trust Company, LLC (“EQ”), the closed-end funds transfer agent, or your financial intermediary, may household the mailing of your documents indefinitely unless you instruct EQ, or your financial intermediary, otherwise. If you would prefer that your Eaton Vance documents not be householded, please contact EQ or your financial intermediary. Your instructions that householding not apply to delivery of your Eaton Vance documents will typically be effective within 30 days of receipt by EQ or your financial intermediary.

Portfolio Holdings. Each Eaton Vance Fund and its underlying Portfolio(s) (if applicable) files a schedule of portfolio holdings on Part F to Form N-PORT with the SEC. Certain information filed on Form N-PORT may be viewed on the Eaton Vance website at www.eatonvance.com, by calling Eaton Vance at 1-800-262-1122 or in the EDGAR database on the SEC’s website at www.sec.gov.

Proxy Voting. From time to time, funds are required to vote proxies related to the securities held by the funds. The Eaton Vance Funds or their underlying Portfolios (if applicable) vote proxies according to a set of policies and procedures approved by the Funds’ and Portfolios’ Boards. You may obtain a description of these policies and procedures and information on how the Funds or Portfolios voted proxies relating to portfolio securities during the most recent 12-month period ended June 30, without charge, upon request, by calling 1-800-262-1122 and by accessing the SEC’s website at www.sec.gov. You may also access proxy voting information for the Eaton Vance Funds or their underlying Portfolios at www.eatonvance.com/
proxyvoting.

Share Repurchase Program. The Fund’s Board of Trustees has approved a share repurchase program authorizing the Fund to repurchase up to 10% of its common shares outstanding as of the last day of the prior calendar year in open-market transactions at a discount to net asset value. The repurchase program does not obligate the Fund to purchase a specific amount of shares. The Fund’s repurchase activity, including the number of shares purchased, average price and average discount to net asset value, is disclosed in the Fund’s annual and semi-annual reports to shareholders.

Additional Notice to Shareholders. If applicable, a Fund may also redeem or purchase its outstanding preferred shares in order to maintain compliance with regulatory requirements, borrowing or rating agency requirements or for other purposes as it deems appropriate or necessary.

Closed-End Fund Information. Eaton Vance closed-end funds make fund performance data and certain information about portfolio characteristics available on the Eaton Vance website shortly after the end of each month. Other information about the funds is available on the website. The funds’ net asset value per share is readily accessible on the Eaton Vance website. Portfolio holdings for the most recent month-end are also posted to the website approximately 30 days following the end of the month. This information is available at www.eatonvance.com on the fund information pages under “Closed-End Funds & Term Trusts.”

Item 2. Code of Ethics

The registrant (sometimes referred to as the “Fund”) has adopted a code of ethics applicable to its Principal Executive Officer, Principal Financial Officer and Principal Accounting Officer. The registrant undertakes to provide a copy of such code of ethics to any person upon request, without charge, by calling 1-800-262-1122. The registrant has not amended the code of ethics as described in Form N-CSR during the period covered by this report. The registrant has not granted any waiver, including an implicit waiver, from a provision of the code of ethics as described in Form N-CSR during the period covered by this report.

Item 3. Audit Committee Financial Expert

The registrant’s Board of Trustees has determined that George J. Gorman, an “independent” Trustee, is an “audit committee financial expert” serving on its audit committee. Under applicable securities laws, a person who is determined to be an audit committee financial expert will not be deemed an “expert” for any purpose, including without limitation for the purposes of Section 11 of the Securities Act of 1933, as a result of being designated or identified as an audit committee financial expert. The designation or identification of a person as an audit committee financial expert does not impose on such person any duties, obligations, or the liabilities that are greater than the duties, obligations, and liabilities imposed on such person as a member of the audit committee and Board of Trustees in the absence of such designation or identification.

Item 4. Principal Accountant Fees and Services

(a) –(d)

The following table presents the aggregate fees billed to the registrant for the registrant’s fiscal years ended December 31, 2024 and December 31, 2025 by the registrant’s principal accountant, Deloitte & Touche LLP (“D&T”), for professional services rendered for the audit of the registrant’s annual financial statements and fees billed for other services rendered by D&T during such periods.


Fiscal Years Ended	12/31/24		12/31/25
Audit Fees	$	59,400	$	56,900
Audit-Related Fees⁽¹⁾	$	0	$	0
Tax Fees⁽²⁾	$	0	$	0
All Other Fees⁽³⁾	$	0	$	0

Total	$	59,400	$	56,900

⁽¹⁾	Audit-related fees consist of the aggregate fees billed for assurance and related services that are reasonably related to the performance of the audit of the registrant’s financial statements and are not reported under the category of audit fees.

⁽²⁾	Tax fees consist of the aggregate fees billed for professional services rendered by the principal accountant relating to tax compliance, tax advice, and tax planning and specifically include fees for tax return preparation and other related tax compliance/planning matters.

⁽³⁾	All other fees consist of the aggregate fees billed for products and services provided by the principal accountant other than audit, audit-related, and tax services.

(e)(1) The registrant’s audit committee has adopted policies and procedures relating to the pre-approval of services provided by the registrant’s principal accountant (the “Pre-Approval Policies”). The Pre-Approval Policies establish a framework intended to assist the audit committee in the proper discharge of its pre-approval responsibilities. As a general matter, the Pre-Approval Policies (i) specify certain types of audit, audit-related, tax, and other services determined to be pre-approved by the audit committee; and (ii) delineate specific procedures governing the mechanics of the pre-approval process, including the approval and monitoring of audit and non-audit service fees. Unless a service is specifically pre-approved under the Pre-Approval Policies, it must be separately pre-approved by the audit committee.

The Pre-Approval Policies and the types of audit and non-audit services pre-approved therein must be reviewed and ratified by the registrant’s audit committee at least annually. The registrant’s audit committee maintains full responsibility for the appointment, compensation, and oversight of the work of the registrant’s principal accountant.

(e)(2) No services described in paragraphs (b)-(d) above were approved by the registrant’s audit committee pursuant to the “de minimis exception” set forth in Rule 2-01(c)(7)(i)(C) of Regulation S-X.

(f) Not applicable.

(g) The following table presents (i) the aggregate non-audit fees (i.e., fees for audit-related, tax, and other services) billed to the registrant by D&T for the registrant’s fiscal years ended December 31, 2024 and December 31, 2025; and (ii) the aggregate non-audit fees (i.e., fees for audit-related, tax, and other services) billed to the Eaton Vance organization by D&T for the same time periods.

⁽¹⁾	The investment adviser to the registrant, as well as any of its affiliates that provide ongoing services to the registrant, are subsidiaries of Morgan Stanley.

(h) The registrant’s audit committee has considered whether the provision by the registrant’s principal accountant of non-audit services to the registrant’s investment adviser and any entity controlling, controlled by, or under common control with the adviser that provides ongoing services to the registrant that were not pre-approved pursuant to Rule 2-01(c)(7)(ii) of Regulation S-X is compatible with maintaining the principal accountant’s independence.

(i) Not applicable.

Item 12. Disclosure of Proxy Voting Policies and Procedures for Closed-End Management Investment Companies

The Board of the Fund has adopted a proxy voting policy and procedure (the “Fund Policy”), pursuant to which the trustees have delegated proxy voting responsibility to the Fund’s investment adviser and adopted the investment adviser’s proxy voting policies and procedures (the “Policies”) which are described below. The trustees will review the Policies annually. In the event that a conflict of interest arises between the Fund’s shareholders and the investment adviser, the administrator, or any of their affiliates or any affiliate of the Fund, the investment adviser will generally refrain from voting the proxies related to the companies giving rise to such conflict until it consults with the Board, or any committee, sub-committee or group of independent trustees identified by the Board, which will instruct the investment adviser on the appropriate course of action. If the Board Members are unable to meet and the failure to vote a proxy would have a material adverse impact on the Fund, the investment adviser may vote such proxy, provided that it discloses the existence of the material conflict to the Chairperson of the Fund’s Board as soon as practicable and to the Board at its next meeting.

The Policies are designed to promote accountability of a company’s management to its shareholders and to align the interests of management with those shareholders. An independent proxy voting service (“Agent”), currently Institutional Shareholder Services, Inc., has been retained to assist in the voting of proxies through the provision of vote analysis, implementation and recordkeeping and disclosure services. The investment adviser will generally vote proxies through the Agent. The Agent is required to vote all proxies in accordance with customized proxy voting guidelines (the “Guidelines”) and/or refer them back to the investment adviser pursuant to the Policies.

The Agent is required to establish and maintain adequate internal controls and policies in connection with the provision of proxy voting services, including methods to reasonably ensure that its analysis and recommendations are not influenced by a conflict of interest. The Guidelines include voting guidelines for matters relating to, among other things, the election of directors, approval of independent auditors, executive compensation, corporate structure and anti-takeover defenses. The investment adviser may cause the Fund to abstain from voting from time to time where it determines that the costs associated with voting a proxy outweigh the benefits derived from exercising the right to vote or it is unable to access or access timely ballots or other proxy information, among other stated reasons. The Agent will refer Fund proxies to the investment adviser for instructions under circumstances where, among others: (1) the application of the Guidelines is unclear; (2) a particular proxy question is not covered by the Guidelines; or (3) the Guidelines require input from the investment adviser. When a proxy voting issue has been referred to the investment adviser, the analyst (or portfolio manager if applicable) covering the company subject to the proxy proposal determines the final vote (or decision not to vote) and the investment adviser’s Proxy Administrator (described below) instructs the Agent to vote accordingly for securities held by the Fund. Where more than one analyst covers a particular company and the recommendations of such analysts voting a proposal conflict, the investment adviser’s Global Proxy Group (described below) will review such recommendations and any other available information related to the proposal and determine the manner in which it should be voted, which may result in different recommendations for the Fund that may differ from other clients of the investment adviser.

The investment adviser has appointed a Proxy Administrator to assist in the coordination of the voting of client proxies (including the Fund’s) in accordance with the Guidelines and the Policies. The investment adviser and its affiliates have also established a Global Proxy Group. The Global Proxy Group develops the investment adviser’s positions on all major corporate issues, creates the Guidelines and oversees the proxy voting process. The Proxy Administrator maintains a record of all proxy questions that have been referred by the Agent, all applicable recommendations, analysis and research received and any resolution of the matter. Before instructing the Agent to vote contrary to the Guidelines or the recommendation of the Agent, the Proxy Administrator will provide the Global Proxy Group with the Agent’s recommendation for the proposal along with any other relevant materials, including the basis for the analyst’s recommendation. The Proxy Administrator will then instruct the Agent to vote the proxy in the manner determined by the Global Proxy Group. A similar process will be followed if the Agent has a conflict of interest with respect to a proxy. The investment adviser will report to the Fund’s Board any votes cast contrary to the Guidelines or Agent recommendations, as applicable, no less than annually.

The investment adviser’s Global Proxy Group is responsible for monitoring and resolving possible material conflicts with respect to proxy voting. Because the Guidelines are predetermined and designed to be in the best interests of shareholders, application of the Guidelines to vote client proxies should, in most cases, adequately address any possible conflict of interest. The investment adviser will monitor situations that may result in a conflict of interest between any of its clients and the investment adviser or any of its affiliates by maintaining a list of significant existing and prospective corporate clients. The Proxy Administrator will compare such list with the names of companies of which he or she has been referred a proxy statement (the “Proxy Companies”). If a company on the list is also a Proxy Company, the Proxy Administrator will report that fact to the Global Proxy Group. If the Proxy Administrator intends to instruct the Agent to vote in a manner inconsistent with the Guidelines, the Global Proxy Group will first determine, in consultation with legal counsel if necessary, whether a material conflict exists. If it is determined that a material conflict exists, the investment adviser will seek instruction on how the proxy should be voted from the Fund’s Board, or any committee or subcommittee identified by the Board. If a matter is referred to the Global Proxy Group, the decision made and basis for the decision will be documented by the Proxy Administrator and/or Global Proxy Group.

Information on how the Fund voted proxies relating to portfolio securities during the most recent 12 month period ended June 30 is available (1) without charge, upon request, by calling 1-800-262-1122, and (2) on the Securities and Exchange Commission’s website at http://www.sec.gov.

Item 13. Portfolio Managers of Closed-End Management Investment Companies

Eaton Vance Management (“EVM” or “Eaton Vance”) is the investment adviser of the Fund. Charles B. Gaffney and Douglas R. Rogers, CFA, CMT are responsible for the overall and day-to-day management of the Fund’s investments. Messrs. Gaffney and Rogers are Vice Presidents of Eaton Vance, have managed other Eaton Vance portfolios for more than five years, and have been portfolio managers of the Fund since May 2023.

Potential for Conflicts of Interest. It is possible that conflicts of interest may arise in connection with a portfolio manager’s management of the Fund’s investments on the one hand and the investments of other accounts for which a portfolio manager is responsible on the other. For example, a portfolio manager may have conflicts of interest in allocating management time, resources and investment opportunities among the Fund and other accounts he advises. In addition, due to differences in the investment strategies or restrictions between the Fund and the other accounts, the portfolio manager may take action with respect to another account that differs from the action taken with respect to the Fund. In some cases, another account managed by a portfolio manager may compensate the investment adviser based on the performance of the securities held by that account. The existence of such a performance based fee may create additional conflicts of interest for the portfolio manager in the allocation of management time, resources and investment opportunities. Whenever conflicts of interest arise, the portfolio manager will endeavor to exercise his discretion in a manner that he or she believes is equitable to all interested persons. EVM has adopted several policies and procedures designed to address these potential conflicts including a code of ethics and policies that govern the investment adviser’s trading practices, including among other things the aggregation and allocation of trades among clients, brokerage allocations, cross trades and best execution.

Compensation Structure for EVM

The compensation structure of Eaton Vance and its affiliates that are investment advisers (for purposes of this section “Eaton Vance”) is based on a total reward system of base salary and incentive compensation, which is paid either in the form of cash bonus, or for employees meeting the specified deferred compensation eligibility threshold, partially as a cash bonus and partially as mandatory deferred compensation. Deferred compensation granted to Eaton Vance employees is generally granted as a mix of deferred cash awards under the Investment Management Alignment Plan (IMAP) and equity-based awards in the form of stock units. The portion of incentive compensation granted in the form of a deferred compensation award and the terms of such awards are determined annually by the Compensation, Management Development and Succession Committee of Morgan Stanley.

Base salary compensation. Generally, portfolio managers receive base salary compensation based on the level of their position with the adviser.

Incentive compensation. In addition to base compensation, portfolio managers may receive discretionary year-end compensation. Incentive compensation may include:

•

Cash bonus

•

Deferred compensation:

•

A mandatory program that defers a portion of incentive compensation into restricted stock units or other awards based on Morgan Stanley common stock or other plans that are subject to vesting and other conditions.

•

IMAP is a cash-based deferred compensation plan designed to increase the alignment of participants’ interests with the interests of clients. For eligible employees, a portion of their deferred compensation is mandatorily deferred into IMAP on an annual basis. Awards granted under IMAP are notionally invested in referenced funds available pursuant to the plan, which are funds advised by MSIM and its affiliates that are investment advisers. Portfolio managers are required to notionally invest a minimum of 40% of their account balance in the designated funds that they manage and are included in the IMAP notional investment fund menu.

•

Deferred compensation awards are typically subject to vesting over a multi-year period and are subject to cancellation through the payment date for competition, cause (i.e., any act or omission that constitutes a breach of obligation to the Funds, including failure to comply with internal compliance, ethics or risk management standards, and failure or refusal to perform duties satisfactorily, including supervisory and management duties), disclosure of proprietary information, and solicitation of employees or clients. Awards are also subject to clawback through the payment date if an employee’s act or omission (including with respect to direct supervisory responsibilities) causes a restatement of the firm’s consolidated financial results, constitutes a violation of the firm’s global risk management principles, policies and standards, or causes a loss of revenue associated with a position on which the employee was paid and the employee operated outside of internal control policies.

Eaton Vance compensates employees based on principles of pay-for-performance, market competitiveness and risk management. Eligibility for, and the amount of any, discretionary compensation is subject to a multi-dimensional process. Specifically, consideration is given to one or more of the following factors, which can vary by portfolio management team and circumstances:

•

Revenue and profitability of the business and/or each fund/account managed by the portfolio manager

•

Individual contribution and performance

•

Contribution to client objectives

•

Revenue and profitability of the firm

•

Return on equity and risk factors of both the business units and Morgan Stanley

•

Assets managed by the portfolio manager

•

External market conditions

•

New business development and business sustainability

•

Team, product and/or Eaton Vance performance

•

The pre-tax investment performance of the funds/accounts managed by the portfolio manager⁽¹⁾ (which may, in certain cases, be measured against the applicable benchmark(s) and/or peer group(s) over one, three and five-year periods),⁽²⁾ provided that for funds that are tax-managed or otherwise have an objective of after-tax returns, performance net of taxes will be considered

Further, the firm’s Global Incentive Compensation Discretion Policy requires compensation managers to consider only legitimate, business related factors when exercising discretion in determining variable incentive compensation, including adherence to Morgan Stanley’s core values, conduct, disciplinary actions in the current performance year, risk management and risk outcomes.

(1)	Generally, this is total return performance, provided that consideration may also be given to relative risk- adjusted performance.

(2)

When a fund’s peer group as determined by Lipper or Morningstar is deemed by the relevant Eaton Vance Chief Investment Officer, or in the case of the sub-advised Funds, the Director of Product Development and Sub-Advised Funds, not to provide a fair comparison, performance may instead be evaluated primarily against a custom peer group or market index.
