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.

Fund Profile

Credit Quality (% of total investments)1,2

Footnotes:

For purposes of the Fund’s rating restrictions, ratings are based on Moody’s Investors Service, Inc. (“Moody’s”), S&P Global Ratings (“S&P”) or Fitch

Ratings (“Fitch”), as applicable. If securities are rated differently by the ratings agencies, the highest rating is applied. Ratings, which are subject to

change, apply to the creditworthiness of the issuers of the underlying securities and not to the Fund or its shares. Credit ratings measure the quality of a

bond based on the issuer’s creditworthiness, with ratings ranging from AAA, being the highest, to D, being the lowest based on S&P’s measures. Ratings

of BBB or higher by S&P or Fitch (Baa or higher by Moody’s) are considered to be investment-grade quality. Credit ratings are based largely on the ratings

agency’s analysis at the time of rating. The rating assigned to any particular security is not necessarily a reflection of the issuer’s current financial

condition and does not necessarily reflect its assessment of the volatility of a security’s market value or of the liquidity of an investment in the security.

Holdings designated as “Not Rated” (if any) are not rated by the national ratings agencies stated above.

The chart includes the municipal bonds held by a trust that issues residual interest bonds, consistent with the Portfolio of Investments.

Endnotes and Additional Disclosures

1	Bloomberg 3 Year Municipal Bond Index is an unmanaged index of municipal bonds traded in the U.S. with maturities ranging from 2-4 years. Unless otherwise stated, index returns do not reflect the effect of any applicable sales charges, commissions, expenses, taxes or leverage, as applicable. It is not possible to invest directly in an index.
2	Performance results reflect the effects of leverage.
3	The shares of the Fund often trade at a discount or premium to their net asset value. The discount or premium may vary over time and may be higher or lower than what is quoted in this report. For up-to-date premium/discount information, please refer to https://funds.eatonvance.com/closed-end-fund-prices.php.
4	The Distribution Rate is calculated by dividing the Fund’s last regular distribution paid per share in the period (annualized) by the Fund’s NAV or market price (the price at which the Fund is traded on the exchange) at the end of the period. A Fund’s distributions in any period may be more or less than the net return earned by the Fund on its investments and should not be used as a measure of performance or confused with “yield” or “income.” The Fund has adopted a policy to pay common shareholders a stable monthly distribution. A portion of the Fund’s distributions may be subject to the U.S. federal alternative minimum tax. In an effort to maintain a stable distribution amount, the Fund may pay distributions consisting of amounts characterized for U.S. federal income tax purposes as exempt-interest dividends, ordinary dividends (including qualified dividends), capital gain distributions and nondividend distributions, also known as return of capital distributions. A nondividend or return of capital distribution results from a Fund distributing more than its net investment income and net realized capital gain for a given tax period and may represent a return of some or all of the money that an investor invested in the Fund’s shares, which, like other distributions, can cause the Fund’s NAV to erode. There is no assurance that the Fund will always be able to pay distributions of a particular size. With each distribution, the Fund issues a notice to shareholders and a press release containing information about the amount and sources of the distribution and related information. Notices and press releases for the last 24 months are available on our website https://www. eatonvance.com/resources/closed-end-fund-distribution-notices-19a.html. The amounts and sources of distributions are only estimates and are not provided for tax reporting purposes. The U.S. federal income tax character of distributions paid to a shareholder is reported on IRS Form 1099-DIV, which is provided to shareholders shortly after the end of each calendar year. The amount of the Fund’s distributions is determined by the investment adviser based on its current assessment of the Fund’s long-term return potential. Fund distributions may be affected by numerous factors including changes in Fund performance, the cost of financing for Funds that employ leverage, portfolio holdings, realized and projected returns, and other factors. As portfolio and market conditions change, the rate of distributions paid by the Fund could change. Shareholders should not assume that the source of any distribution from the Fund is net income or profit. Taxable-equivalent distributions are calculated using a 40.8% U.S. federal income tax rate, which reflects the maximum U.S. federal tax

rate of 37% plus the 3.8% U.S. federal Medicare surtax. Where

applicable, the calculation also includes the highest individual U.S.

state income tax rate for residents of the state for which a Fund’s

income is designed to be exempt. Local income taxes and other

applicable taxes are not considered in the calculation.

Fund employs RIB financing. The leverage created by RIB investments

provides an opportunity for increased income but, at the same time,

creates special risks (including the likelihood of greater price

volatility). The cost of leverage rises and falls with changes in

short-term interest rates. See “Floating Rate Notes Issued in

Conjunction with Securities Held” in the notes to the financial

statements for more information about RIB financing. RIB leverage

represents the amount of Floating Rate Notes outstanding at period

end as a percentage of Fund net assets plus Floating Rate Notes.

Fund profile subject to change due to active management.

1 Significant Accounting Policies

Eaton Vance Municipal Income 2028 Term Trust (the Trust) 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 Trust's investment objective is to provide current income exempt from regular federal income tax. The Trust has a term of fifteen years and currently intends to cease its investment operations on or about June 30, 2028 (the “Termination Date”) and thereafter liquidate and distribute its net assets to holders of the Trust’s common shares. The Trust’s term may be extended for a period of not more than 12 months from the Termination Date by a vote of the Trust’s Board of Trustees, if the Board determines it is in the best interest of the common shareholders to do so. The Trust’s term may not be extended further than a 12 month period without a common shareholder
vote.

The following is a summary of significant accounting policies of the Trust. The policies are in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP). The Trust 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.

Debt Obligations. Debt obligations are generally valued on the basis of valuations provided by third party pricing services, as derived from such services’ pricing models. Inputs to the models may include, but are not limited to, reported trades, executable bid and ask prices, broker/dealer quotations, prices or yields of securities with similar characteristics, interest rates, anticipated prepayments, benchmark curves or information pertaining to the issuer, as well as industry and economic events. The pricing services may use a matrix approach, which considers information regarding securities with similar characteristics to determine the valuation for a security. Short-term debt obligations purchased with a remaining maturity of sixty days or less for which a valuation from a third party pricing service is not readily available may be valued at amortized cost, which approximates fair value.

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 Trust’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 Trust 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 and Related Income—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. Interest income is recorded on the basis of interest accrued, adjusted for amortization of premium or accretion of discount. Dividend income is recorded on the ex-dividend date for dividends received in cash and/or securities.

C Federal and Other Taxes—The Trust’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 taxable, if any, and tax-exempt 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. The Trust intends to satisfy conditions which will enable it to designate distributions from the interest income generated by its investments in non-taxable municipal securities, which are exempt from regular federal income tax when received by the Trust, as exempt-interest dividends. The portion of such interest, if any, earned on private activity bonds issued after August 7, 1986, may be considered a tax preference item to shareholders.

As of July 31, 2026, the Trust had no uncertain tax positions that would require financial statement recognition, de-recognition, or disclosure. The Trust 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.

D Legal Fees— Legal fees and other related expenses incurred as part of negotiations of the terms and requirement of capital infusions, or that are expected to result in the restructuring of, or a plan of reorganization for, an investment are recorded as realized losses. Ongoing expenditures to protect or enhance an investment are treated as operating expenses.

E 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.

F Indemnifications—Under the Trust’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 Trust. Under Massachusetts law, if certain conditions prevail, shareholders of a Massachusetts business trust (such as the Trust) could be deemed to have personal liability for the obligations of the Trust. However, the Trust’s Declaration of Trust contains an express disclaimer of liability on the part of Trust shareholders and the By-laws provide that the Trust shall assume, upon request by the shareholder, the defense on behalf of any Trust shareholders. Moreover, the By-laws also provide for indemnification out of Trust 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 Trust enters into agreements with service providers that may contain indemnification clauses. The Trust's maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Trust that have not yet occurred.

G Floating Rate Notes Issued in Conjunction with Securities Held—The Trust may invest in residual interest bonds, also referred to as inverse floating rate securities, whereby the Trust may sell a variable or fixed rate bond for cash to a Special-Purpose Vehicle (the SPV), (which is generally organized as a trust), while at the same time, buying a residual interest in the assets and cash flows of the SPV. The bond is deposited into the SPV with the same CUSIP number as the bond sold to the SPV by the Trust, and which may have been, but is not required to be, the bond purchased from the Trust (the Bond). The SPV also issues floating rate notes (Floating Rate Notes) which are sold to third-parties. The residual interest bond held by the Trust gives the Trust the right (1) to cause the holders of the Floating Rate Notes to generally tender their notes at par, and (2) to have the Bond held by the SPV transferred to the Trust, thereby terminating the SPV. Should the Trust exercise such right, it would generally pay the SPV the par amount due on the Floating Rate Notes and exchange the residual interest bond for the underlying Bond. Pursuant to generally accepted accounting principles for transfers and servicing of financial assets and extinguishment of liabilities, the Trust accounts for the transaction described above as a secured borrowing by including the Bond in its Portfolio of Investments and the Floating Rate Notes as a liability under the caption “Payable for floating rate notes issued” in its Statement of Assets and Liabilities. The Floating Rate Notes have interest rates that generally reset weekly and their holders have the option to tender their notes to the SPV for redemption at par at each reset date. Accordingly, the fair value of the payable for floating rate notes issued approximates its carrying value. If measured at fair value, the payable for floating rate notes would have been considered as Level 2 in the fair value hierarchy (see Note 6) at July 31, 2026. Interest expense related to the Trust's liability with respect to Floating Rate Notes is recorded as incurred. The SPV may be terminated by the Trust, as noted above, or by the occurrence of certain termination events as defined in the trust agreement, such as a downgrade in the credit quality of the underlying Bond, bankruptcy of or payment failure by the issuer of the underlying Bond, the inability to remarket Floating Rate Notes that have been tendered due to insufficient buyers in the market, or the failure by the SPV to obtain renewal of the liquidity agreement under which liquidity support is provided for the Floating Rate Notes up to one year. At July 31, 2026, the amount of the Trust’s Floating Rate Notes outstanding and the related collateral were $6,669,994 and $9,780,900, respectively. The interest rate on the Floating Rate Notes outstanding at July 31, 2026 was 2.23%. For the six months ended July 31, 2026, the Trust’s average settled Floating Rate Notes outstanding and the average interest rate (annualized) including fees were $6,670,000 and 2.97%, respectively.

In certain circumstances, the Trust may enter into shortfall and forbearance agreements with brokers by which the Trust agrees to reimburse the broker for the difference between the liquidation value of the Bond held by the SPV and the liquidation value of the Floating Rate Notes, as well as any shortfalls in interest cash flows. The Trust had no shortfalls as of July 31, 2026.

The Trust may also purchase residual interest bonds in a secondary market transaction without first owning the underlying bond. Such transactions are not required to be treated as secured borrowings. Shortfall agreements, if any, related to residual interest bonds purchased in a secondary market transaction are disclosed in the Portfolio of Investments.

The Trust’s investment policies and restrictions expressly permit investments in residual interest bonds. Such bonds typically offer the potential for yields exceeding the yields available on fixed rate bonds with comparable credit quality and maturity. These securities tend to underperform the market for fixed rate bonds in a rising long-term interest rate environment, but tend to outperform the market for fixed rate bonds when long-term interest rates decline. The value and income of residual interest bonds are generally more volatile than that of a fixed rate bond. The Trust’s investment policies do not allow the Trust to borrow money except as permitted by the 1940 Act. Effective August 19, 2022, the Trust began operating under Rule 18f-4 under the 1940 Act, which, among other things, governs the use of derivative investments and certain financing transactions by registered investment companies. Consistent with Rule 18f-4, the Trust may treat its investments in residual interest bonds and similar financing transactions as subject to the asset coverage requirements of Section 18 of the 1940 Act, or as derivatives transactions subject to the Trust's value-at-risk (VaR)-based limits on leverage risk. Effective October 11, 2023, the Trust has opted to treat such investments as derivatives transactions. The Trust may change this approach at any time. Residual interest bonds held by the Trust are securities exempt from registration under Rule 144A of the Securities Act of 1933.

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

I Interim Financial Statements—The interim financial statements relating to July 31, 2026 and for the six months then ended have not been audited by an independent registered public accounting firm, but in the opinion of the Trust’s management, reflect all adjustments, consisting only of normal recurring adjustments, necessary for the fair presentation of the financial statements.

2 Distributions to Shareholders and Income Tax Information

The Trust intends to make monthly distributions of net investment income to common shareholders. In addition, at least annually, the Trust 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 return of capital component. For the six months ended July 31, 2026, the amount of distributions estimated to be a tax return of capital was approximately $1,673,000. The final determination of tax characteristics of the Trust's distributions will occur at the end of the year, at which time it will be reported to the shareholders.

At January 31, 2026, the Trust, for federal income tax purposes, had deferred capital losses of $6,239,598 which would reduce its taxable income arising from future net realized gains on investment transactions, if any, to the extent permitted by the Internal Revenue Code, and thus would reduce the amount of distributions to shareholders, which would otherwise be necessary to relieve the Trust of any liability for federal income or excise tax. The deferred capital losses are treated as arising on the first day of the Trust’s next taxable year and retain the same short-term or long-term character as when originally deferred. Of the deferred capital losses at January 31, 2026, $6,204,534 are short-term and $35,064 are long-term.

The cost and unrealized appreciation (depreciation) of investments of the Trust at July 31, 2026, as determined on a federal income tax basis, were as follows:

Aggregate cost	$191,693,049
Gross unrealized appreciation	$4,680,359
Gross unrealized depreciation	(476,269 )
Net unrealized appreciation	$4,204,090

3 Investment Adviser and Administration Fee and Other Transactions with Affiliates

The investment adviser and administration fee is earned by Eaton Vance Management (EVM), an indirect, wholly-owned subsidiary of Morgan Stanley, as compensation for investment advisory and administrative services rendered to the Trust. The fee is computed at an annual rate of 0.60% of the Trust’s average daily total managed assets and is payable monthly. For purposes of this calculation, total managed assets means total assets of the Trust, including any form of investment leverage, minus all accrued expenses incurred in the normal course of operations, but not excluding any liabilities or obligations attributable to investment leverage obtained through (i) indebtedness of any type (including, without limitation, borrowing through a credit facility or the issuance of debt securities or through the purchase of residual interest bonds), (ii) the issuance of preferred stock or other similar preference securities, (iii) the reinvestment of collateral received for securities loaned in accordance with the Trust’s investment objectives and policies, and/or (iv) any other means, all as determined in accordance with generally accepted accounting principles. Accrued expenses includes other liabilities other than indebtedness attributable to leverage. For the six months ended July 31, 2026, the investment adviser and administration fee was $613,881.

Trustees and officers of the Trust who are members of EVM’s organization receive remuneration for their services to the Trust out of the investment adviser and administration fee. Trustees of the Trust 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 Trust are officers of EVM.

4 Purchases and Sales of Investments

Purchases and sales of investments, other than short-term obligations and including maturities, aggregated $19,399,300 and $20,977,672, respectively, for the six months ended July 31, 2026.

5 Common Shares of Beneficial Interest

The Trust may issue common shares pursuant to its dividend reinvestment plan. Common shares issued by the Trust pursuant to its dividend reinvestment plan for the six months ended July 31, 2026 and the year ended January 31, 2026 were 6,385 and 7,637, respectively.

In November 2013, the Board of Trustees initially approved a share repurchase program for the Trust. Pursuant to the reauthorization of the share repurchase program by the Board of Trustees in March 2019, the Trust 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 Trust to purchase a specific amount of shares. There were no repurchases of common shares by the Trust for the six months ended July 31, 2026 and the year ended January 31, 2026.

6 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 July 31, 2026, the hierarchy of inputs used in valuing the Trust's investments, which are carried at fair value, were as follows:

Asset Description	Level 1	Level 2	Level 3	Total
Tax-Exempt Municipal Obligations	$ —	$190,328,490	$ —	$190,328,490
Taxable Municipal Obligations	—	12,054,589	—	12,054,589
Short-Term Investments	184,054	—	—	184,054
Total Investments	$184,054	$202,383,079	$ —	$202,567,133

Board of Trustees’ Contract Approval

Overview of the Contract Review Process

The Investment Company Act of 1940, as amended (the “1940 Act”), provides, in substance, that the investment advisory agreement between a fund and its investment adviser will continue in effect from year-to-year only if its continuation is approved on an annual basis by a vote of the fund’s board of trustees, including a majority of the trustees who are not “interested persons” of the fund (“independent trustees”), cast in person at a meeting called for the purpose of considering such approval.

At a meeting held on June 11, 2026, the Boards of Trustees/Directors (collectively, the “Board”) that oversee the registered investment companies advised by Eaton Vance Management or its affiliate, Boston Management and Research (the “Eaton Vance Funds”), including a majority of the independent trustees (the “Independent Trustees”), voted to approve the continuation of existing investment advisory agreements and sub-advisory agreements1 for each of the Eaton Vance Funds for an additional one-year period. The Board relied upon the affirmative recommendation of its Contract Review Committee, which is a committee comprised of all of the Independent Trustees. Prior to making its recommendation, the Contract Review Committee reviewed information furnished by the adviser and sub-adviser to each of the Eaton Vance Funds (including information specifically requested by the Board) for a series of meetings held between April and June 2026, as well as certain additional information provided in response to specific requests from the Independent Trustees as members of the Contract Review Committee. Members of the Contract Review Committee also considered information received at prior meetings of the Board and its committees, to the extent such information was relevant to the Contract Review Committee’s annual evaluation of the investment advisory agreements and sub-advisory agreements.

In connection with its evaluation of the investment advisory agreements and sub-advisory agreements, the Board (directly or through one or more of its committees) considered various information relating to the Eaton Vance Funds. This included information applicable to all or groups of the Eaton Vance Funds, which is referenced immediately below, and information applicable to the particular Eaton Vance Fund covered by this report (each Eaton Vance Fund is referred to below as a “fund”). (For funds that invest through one or more underlying portfolios, references to “each fund” in this section may include information that was considered at the portfolio-level.)

Information about Fees, Performance and Expenses

• A report from an independent data provider comparing advisory and other fees paid by each fund to such fees paid by comparable funds, as identified by the independent data provider (“comparable funds”);

• A report from an independent data provider comparing each fund’s total expense ratio (and its components) to those of comparable funds;

During the various meetings of the Board and its committees over the course of the year leading up to the June 11, 2026 meeting, the Board and its committees received information from portfolio managers and other investment professionals of the adviser and sub-advisers of the funds regarding investment and performance matters, and considered various investment and trading strategies used in pursuing the funds’ investment objectives. The Board and its committees also received information regarding risk management techniques employed in connection with the management of the funds. The Board and its committees evaluated issues pertaining to industry and regulatory developments, compliance procedures, fund governance, and other issues with respect to the funds, and received and participated in reports and presentations provided by the adviser, sub-advisers, and certain other service providers, with respect to such matters. In addition to the formal meetings of the Board and its committees, the Independent Trustees met in executive sessions and held regular video or telephone conferences to discuss, among other topics, matters relating to the continuation of investment advisory agreements and sub-advisory agreements.

Each of the Contract Review Committee and the Board was advised throughout the contract review process by Kirkland & Ellis LLP, independent legal counsel for the Independent Trustees. The members of the Contract Review Committee and the members of the Board, with the advice of such counsel, exercised their own business judgment in determining the material factors to be considered in evaluating each investment advisory agreement and sub-advisory agreement and the weight to be given to each such factor. The conclusions reached with respect to each investment advisory agreement and sub-advisory agreement were based on a comprehensive evaluation of all the information provided and not any single factor. Moreover, each member of the Contract Review Committee and Board may have placed varying emphasis on particular factors in reaching conclusions with respect to each investment advisory agreement and sub-advisory agreement. In evaluating each investment advisory agreement and sub-advisory agreement, including the fee structures and other terms contained in such agreements, the members of the Contract Review Committee and Board were also informed by multiple years of analysis and discussion with the adviser and sub-adviser to each of the Eaton Vance Funds.

Results of the Contract Review Process

Based on its consideration of the foregoing, and such other information it deemed relevant, including the factors and conclusions described below, the Contract Review Committee concluded that the continuation of the investment advisory and administrative agreement between Eaton Vance Municipal Income 2028 Term Trust (the “Fund”) and Eaton Vance Management (the “Adviser”), including its fee structure, is in the interests of shareholders and, therefore, recommended to the Board approval of the agreement. Based on the recommendation of the Contract Review Committee, the Board, including a majority of the Independent Trustees, voted to approve continuation of the investment advisory and administrative agreement for the Fund.

Nature, Extent and Quality of Services

In considering whether to approve the investment advisory and administrative agreement for the Fund, the Board evaluated the nature, extent and quality of services provided to the Fund by the Adviser.

The Board considered the Adviser’s management capabilities and investment processes in light of the types of investments held by the Fund, including the education and experience of the investment professionals who provide services to the Fund. In particular, the Board considered, where relevant, the abilities and experience of the Adviser’s investment professionals in analyzing factors such as credit risk, tax efficiency, and special considerations relevant to investing in municipal bonds. The Board considered the Adviser’s municipal bond team, which includes investment professionals and credit specialists who provide services to the Fund. The Board also considered information regarding the management of the Fund’s portfolio in the context of the target term structure and noted the Adviser’s experience with this structure. The Board also took into account the resources dedicated to portfolio management and other services, the compensation methods of the Adviser and other factors, including the reputation and resources of the Adviser to recruit and retain highly qualified research, advisory and supervisory investment professionals. In addition, the Board considered the time and attention devoted to the Eaton Vance Funds, including the Fund, by senior management, as well as the infrastructure, operational capabilities and support staff in place to assist in the portfolio management and operations of the Fund, including the provision of administrative services. The Board also considered the business-related and other risks to which the Adviser or its affiliates may be subject in managing the Fund. The Board considered the deep experience of the Adviser and its affiliates with managing and operating funds organized as exchange-listed closed-end funds, such as the Fund. In this regard, the Board considered, among other things, the Adviser’s and its affiliates’ experience with implementing leverage arrangements, monitoring and assessing trading price discounts and premiums and adhering to the requirements of securities exchanges.

The Board considered the compliance programs of the Adviser and relevant affiliates thereof. The Board considered compliance and reporting matters regarding, among other things, personal trading by investment professionals, disclosure of portfolio holdings, compliance with policies and procedures, portfolio valuation, business continuity and the allocation of investment opportunities. The Board also considered relevant examinations of the Adviser and its affiliates by regulatory authorities, such as the Securities and Exchange Commission and the Financial Industry Regulatory Authority.

The Board considered other administrative services provided or overseen by Eaton Vance Management and its affiliates, including transfer agency and accounting services. The Board evaluated the benefits to shareholders of investing in a fund that is a part of a large fund complex offering exposure to a variety of asset classes and investment disciplines.

After consideration of the foregoing factors, among others, the Board concluded that the nature, extent and quality of services provided by the Adviser, taken as a whole, are appropriate and consistent with the terms of the investment advisory and administrative agreement.

Fund Performance

The Board compared the Fund’s investment performance to that of comparable funds identified by an independent data provider (the peer group), as well as appropriate benchmark indices, and assessed the Fund’s performance on the basis of total return and current income return. The Board’s review included comparative performance data with respect to the Fund for the one-, three-, five- and ten-year periods ended December 31, 2025. In this regard, the Board noted that the performance of the Fund was lower than the median performance of the Fund’s peer group for the three-year period. The Board also noted that the performance of the Fund was higher than its primary and secondary performance benchmark indexes for the three-year period. The Board considered, among other things, the Adviser’s efforts to generate competitive levels of tax-exempt current income through investments that, relative to its comparable funds, focus on higher quality municipal bonds with longer maturities. On the basis of the foregoing, the performance of the Fund over other periods, and other relevant information provided by the Adviser in response to requests from the Contract Review Committee, the Board concluded that the performance of the Fund was satisfactory.

Management Fees and Expenses

The Board considered contractual fee rates payable by the Fund for advisory and administrative services (referred to collectively as “management fees”). As part of its review, the Board considered the Fund’s management fees and total expense ratio for the one-year period ended December 31, 2025, as compared to those of comparable funds, before and after giving effect to any undertaking to waive fees or reimburse expenses. The Board also considered certain factors identified by management in response to requests from the Contract Review Committee regarding the Fund’s total expense ratio relative to comparable funds.

After considering the foregoing information, and in light of the nature, extent and quality of the services provided by the Adviser, the Board concluded that the management fees charged for advisory and related services are reasonable.

Profitability and “Fall-Out” Benefits

The Board considered the level of profits realized by the Adviser and relevant affiliates thereof in providing investment advisory and administrative services to the Fund and to all Eaton Vance Funds as a group. The Board considered the level of profits realized without regard to marketing support or other payments by the Adviser and its affiliates to third parties in respect of distribution or other services.

The Board concluded that, in light of the foregoing factors and the nature, extent and quality of the services rendered, the profits realized by the Adviser and its affiliates are not excessive.

The Board also considered direct and indirect fall-out benefits received by the Adviser and its affiliates in connection with their respective relationships with the Fund and the other Eaton Vance Funds, including, among other things, fees for trading, distribution and/or shareholder servicing and for transaction processing and reporting platforms used by securities lending agent(s), and research received by each Adviser generated from commission dollars spent on funds’ portfolio trading.

Economies of Scale

In reviewing management fees and profitability, the Board also considered the extent to which the Adviser and its affiliates, on the one hand, and the Fund, on the other hand, can expect to realize benefits from economies of scale as the assets of the Fund increase. The Board acknowledged the difficulty in accurately measuring the benefits resulting from economies of scale, if any, with respect to the management of any specific fund or group of funds. To assist in the evaluation of the sharing of any economies of scale, the Board received data for recent years showing asset levels, Adviser profitability and total expense ratios. Based upon the foregoing, the Board concluded that the Fund currently shares in the benefits from economies of scale, if any, when they are realized by the Adviser. The Board also considered the fact that the Fund is not continuously offered and that the Fund’s assets are not expected to increase materially in the foreseeable future. Accordingly, the Board did not find that the implementation of breakpoints in the advisory fee schedule is warranted at this time.

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.
