Eaton VanceTax-Managed Buy-WriteStrategy Fund (EXD)

Semiannual ReportJune 30, 2021

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

and Parametric Portfolio Associates LLC (Parametric), sub-adviser to the Fund, are registered with the CFTC as commodity pool

operators. The adviser and Parametric are also registered as commodity trading advisors.

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 $0.0708 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.

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 otherexpenses by determining the percentage change in net asset value (NAV) or market price (as applicable) with all distributionsreinvested in accordance with the Fund’s Dividend Reinvestment Plan. Performance at market price will differ from performance atNAV due to variations in the Fund’s market price versus NAV, which may reflect factors such as fluctuations in supply and demand forFund shares, changes in Fund distributions, shifting market expectations for the Fund’s future returns and distribution rates, and otherconsiderations 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 thequoted return.

1 Significant Accounting Policies

Eaton Vance Tax-Managed Buy-Write Strategy 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 currentincome and gains, with a secondary objective of capital appreciation. In pursuing its investment objectives, the Fund evaluates returns on an after-taxbasis, seeking to minimize and defer shareholder federal income taxes. The Fund’s investment strategy consists of owning a diversified portfolio of commonstocks and selling covered index call options (a “buy-write strategy”).

The following is a summary of significant accounting policies of the Fund. The policies are in conformity with accounting principles generally accepted inthe United States of America (U.S. GAAP). The Fund is an investment company and follows accounting and reporting guidance in the Financial AccountingStandards 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 nosales took place on such date, at the mean between the closing bid and ask prices on the exchange where such securities are principally traded. Equitysecurities listed on the NASDAQ Global or Global Select Market generally are valued at the NASDAQ official closing price. Unlisted or listed securities forwhich 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 PriceReporting Authority. Non-U.S. exchange-traded options and over-the-counter options are valued by a third party pricing service using techniques thatconsider factors including the value of the underlying instrument, the volatility of the underlying instrument and the period of time until option expiration.

Affiliated Fund. The Fund may invest in Eaton Vance Cash Reserves Fund, LLC (Cash Reserves Fund), an affiliated investment company managed byEaton Vance Management (EVM). While Cash Reserves Fund is not a registered money market mutual fund, it conducts all of its investment activities inaccordance with the requirements of Rule 2a-7 under the 1940 Act. Investments in Cash Reserves Fund are valued at the closing net asset value per uniton the valuation day. Cash Reserves Fund generally values its investment securities based on available market quotations provided by a third party pricingservice.

Fair Valuation. Investments for which valuations or market quotations are not readily available or are deemed unreliable are valued at fair value usingmethods determined in good faith by or at the direction of the Trustees of the Fund in a manner that most fairly reflects the security’s “fair value”, which isthe amount that the Fund might reasonably expect to receive for the security upon its current sale in the ordinary course. Each such determination is basedon 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, thetype of security, the existence of any contractual restrictions on the security’s disposition, the price and extent of public trading in similar securities of theissuer or of comparable companies or entities, quotations or relevant information obtained from broker/dealers or other market participants, informationobtained from the issuer, analysts, and/or the appropriate stock exchange (for exchange-traded securities), an analysis of the company’s or entity’s financialstatements, 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 losseson 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.

D Federal Taxes — The Fund’s policy is to comply with the provisions of the Internal Revenue Code applicable to regulated investment companies and todistribute 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 June 30, 2021, the Fund had no uncertain tax positions that would require financial statement recognition, de-recognition, or disclosure. The Fundfiles 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 ofthree years from the date of filing.

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

F Indemnifications — Under the Fund’s organizational documents, its officers and Trustees may be indemnified against certain liabilities and expensesarising out of the performance of their duties to the Fund. Under Massachusetts law, if certain conditions prevail, shareholders of a Massachusetts businesstrust (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 anexpress disclaimer of liability on the part of Fund shareholders and the By-laws provide that the Fund shall assume, upon request by the shareholder, thedefense on behalf of any Fund shareholders. Moreover, the By-laws also provide for indemnification out of Fund property of any shareholder held personallyliable solely by reason of being or having been a shareholder for all loss or expense arising from such liability. Additionally, in the normal course ofbusiness, the Fund enters into agreements with service providers that may contain indemnification clauses. The Fund’s maximum exposure under thesearrangements is unknown as this would involve future claims that may be made against the Fund that have not yet occurred.

Notes to Financial Statements (Unaudited) — continued

G 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 asa liability. The amount of the liability is subsequently marked-to-market to reflect the current market value of the option written, in accordance with theFund’s policies on investment valuations discussed above. Premiums received from writing options which expire are treated as realized gains. Premiumsreceived from writing options which are exercised or are closed are added to or offset against the proceeds or amount paid on the transaction to determinethe 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 exerciseprice 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 caseof 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, asa 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 bearthe risk of not being able to enter into a closing transaction if a liquid secondary market does not exist.

H Interim Financial Statements — The interim financial statements relating to June 30, 2021 and for the six months then ended have not been audited byan independent registered public accounting firm, but in the opinion of the Fund’s management, reflect all adjustments, consisting only of normal recurringadjustments, necessary for the fair presentation of the financial statements.

2 Distributions to Shareholders and Income Tax Information

Subject to its Managed Distribution Plan, the Fund intends to make monthly distributions from its net investment income, net capital gain (which is theexcess of net long-term capital gain over net short-term capital loss) and other sources. The Fund intends to distribute all or substantially all of its netrealized capital gains. Distributions are recorded on the ex-dividend date. Distributions to shareholders are determined in accordance with income taxregulations, 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 thefinancial statements as a return of capital. Permanent differences between book and tax accounting relating to distributions are reclassified to paid-incapital. For tax purposes, distributions from short-term capital gains are considered to be from ordinary income. Distributions in any year may include asubstantial return of capital component. For the six months ended June 30, 2021, the amount of distributions estimated to be a tax return of capital wasapproximately $4,134,000. The final determination of tax characteristics of the Fund’s distributions will occur at the end of the year, at which time it willbe reported to the shareholders.

At December 31, 2020, the Fund, for federal income tax purposes, had deferred capital losses of $35,520,175 which would reduce its taxable incomearising from future net realized gains on investment transactions, if any, to the extent permitted by the Internal Revenue Code, and thus would reduce theamount of distributions to shareholders, which would otherwise be necessary to relieve the Fund of any liability for federal income or excise tax. Thedeferred capital losses are treated as arising on the first day of the Fund’s next taxable year and retain the same short-term or long-term character as whenoriginally deferred. Of the deferred capital losses at December 31, 2020, $18,358,299 are short-term and $17,161,876 are long-term.

The cost and unrealized appreciation (depreciation) of investments, including open derivative contracts, of the Fund at June 30, 2021, as determined on afederal income tax basis, were as follows:

Aggregate cost $57,628,793

Gross unrealized appreciation $55,560,266

Gross unrealized depreciation (1,033,101)

Net unrealized appreciation $54,527,165

3 Investment Adviser and Administration Fee and Other Transactions with Affiliates

The investment adviser and administration fee is earned by EVM as compensation for investment advisory and administrative services rendered to theFund. On March 1, 2021, Morgan Stanley acquired Eaton Vance Corp. (the “Transaction”) and EVM became an indirect, wholly-owned subsidiary ofMorgan Stanley. In connection with the Transaction, the Fund entered into a new investment advisory and administrative agreement (the “NewAgreement”) with EVM, which took effect on March 1, 2021. The Fund’s prior fee reduction agreement was incorporated into the New Agreement.Pursuant to the New Agreement (and the Fund’s investment advisory and administrative agreement and related fee reduction agreement in effect prior toMarch 1, 2021), the fee is computed at an annual rate of 1.00% of the Fund’s average daily net assets and is payable monthly. For the six months endedJune 30, 2021, the investment adviser and administration fee amounted to $530,614.

Pursuant to an investment sub-advisory agreement, EVM has delegated a portion of the investment management of the Fund to Parametric PortfolioAssociates LLC (Parametric), an affiliate of EVM and, effective March 1, 2021, an indirect wholly-owned subsidiary of Morgan Stanley. In connection withthe Transaction, EVM entered into a new sub-advisory agreement with Parametric, which took effect on March 1, 2021. EVM pays Parametric a portion ofits investment adviser and administration fee for sub-advisory services provided to the Fund. The Fund may invest its cash in Cash Reserves Fund. EVMdoes not currently receive a fee for advisory services provided to Cash Reserves Fund.

14



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 adviserand administration 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 inaccordance with the terms of the Trustees Deferred Compensation Plan. For the six months ended June 30, 2021, no significant amounts have beendeferred. 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 $1,806,366 and $7,367,142, respectively, for the six months endedJune 30, 2021.

5 Common Shares of Beneficial Interest

The Fund may issue common shares pursuant to its dividend reinvestment plan. Common shares issued by the Fund pursuant to its dividend reinvestmentplan for the six months ended June 30, 2021 were 3,019. There were no common shares issued by the Fund for the year ended December 31, 2020.In November 2013, the Board of Trustees initially approved a share repurchase program for the Fund. Pursuant to the reauthorization of the sharerepurchase 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 thelast 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 notobligate the Fund to purchase a specific amount of shares. There were no repurchases of common shares by the Fund for the six months ended June 30,2021 and the year ended December 31, 2020.

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 mayinclude written options and may involve, to a varying degree, elements of risk in excess of the amounts recognized for financial statement purposes. Thenotional or contractual amounts of these instruments represent the investment the Fund has in particular classes of financial instruments and do notnecessarily represent the amounts potentially subject to risk. The measurement of the risks associated with these instruments is meaningful only when allrelated and offsetting transactions are considered. A summary of obligations under these financial instruments at June 30, 2021 is included in the Portfolioof Investments. At June 30, 2021, 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 writes index call options above the currentvalue of the index to generate premium income. In writing index call options, the Fund in effect, sells potential appreciation in the value of the applicableindex above the exercise price in exchange for the option premium received. The Fund retains the risk of loss, minus the premium received, should theprice of the underlying index decline.

The fair value of open derivative instruments (not considered to be hedging instruments for accounting disclosure purposes) and whose primary underlyingrisk exposure is equity price risk at June 30, 2021 was as follows:

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, isused 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 lowestlevel input that is significant to the fair value measurement in its entirety. The inputs or methodology used for valuing securities are not necessarily anindication of the risk associated with investing in those securities.

At June 30, 2021, the hierarchy of inputs used in valuing the Fund’s investments and open derivative instruments, which are carried at value, were asfollows:

Asset Description Level 1 Level 2 Level 3 Total

Common Stocks $114,316,340* $ — $ — $114,316,340

Short-Term Investments — 113,398 — 113,398

9 Risks and Uncertainties

Pandemic Risk

An outbreak of respiratory disease caused by a novel coronavirus was first detected in China in late 2019 and subsequently spread internationally. Thiscoronavirus has resulted in closing borders, enhanced health screenings, changes to healthcare service preparation and delivery, quarantines,cancellations, disruptions to supply chains and customer activity, as well as general concern and uncertainty. Health crises caused by outbreaks, such asthe coronavirus outbreak, may exacerbate other pre-existing political, social and economic risks and disrupt normal market conditions and operations. Theimpact of this outbreak has negatively affected the worldwide economy, the economies of individual countries, individual companies, and the market ingeneral, and may continue to do so in significant and unforeseen ways, as may other epidemics and pandemics that may arise in the future. Any suchimpact could adversely affect the Fund’s performance, or the performance of the securities in which the Fund invests.

Joint Special Meeting of Shareholders (Unaudited)

The Fund held a Joint Special Meeting of Shareholders (the “Special Meeting”) with certain other Eaton Vance closed-end funds on January 7, 2021 andadjourned until January 22, 2021 for the following purpose: approval of a new investment advisory agreement with EVM (“Proposal 1”) and approval of anew investment sub-advisory agreement with Parametric Portfolio Associates LLC (“Proposal 2”). The shareholder meeting results are as follows:

Number of Shares(1)

For Against Abstain(2)Broker

Non-Votes(2)

Proposal 1 4,589,542 136,912 362,601 0

Proposal 2 4,567,634 146,558 374,861 0

(1) Fractional shares were voted proportionately.(2) All shares that were voted and votes to abstain were counted towards establishing a quorum, as were broker non-votes. (Broker non-votes are shares for which a

broker returns a proxy but for which (i) the beneficial owner has not voted and (ii) the broker holding the shares does not have discretionary authority to vote onthe particular matter.) Abstentions and broker non-votes had the effect of a negative vote on each Proposal. Broker non-votes were not expected with respect toeach Proposal because brokers are required to receive instructions from the beneficial owners or persons entitled to vote in order to submit proxies.
