Eaton Vance
Tax-Managed Growth Fund 1.0
June 30, 2026
Notes to Financial Statements (Unaudited)
1 Significant Accounting Policies
Eaton Vance Tax-Managed Growth Fund 1.0 (the Fund) is a diversified series of the Eaton Vance Series Trust (the Trust). The Trust is a Massachusetts business trust registered under the Investment Company Act of 1940, as amended, as an open-end management investment company. The Fund invests its assets in interests in Tax-Managed Growth Portfolio (the Portfolio), a Massachusetts business trust, having the same investment objective and policies as the Fund. The value of the Fund's investment in the Portfolio reflects the Fund's proportionate interest in the net assets of the Portfolio (24.4% at June 30, 2026). The performance of the Fund is directly affected by the performance of the Portfolio. The financial statements of the Portfolio, including the portfolio of investments, are included elsewhere in this report and should be read in conjunction with the Fund's financial statements.
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 "Financial Services - Investment Companies."
A Investment Valuation- Valuation of securities by the Portfolio is discussed in Note 1A of the Portfolio's Notes to Financial Statements, which are included elsewhere in this report.
B Income-The Fund's net investment income or loss consists of the Fund's pro rata share of the net investment income or loss of the Portfolio, less all actual and accrued expenses of the Fund.
C 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 June 30, 2026, 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.
D Expenses-The majority of expenses of the Trust are directly identifiable to an individual fund. Expenses which are not readily identifiable to a specific fund are allocated taking into consideration, among other things, the nature and type of expense and the relative size of the funds.
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 Fund. 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 Fund shareholders and the By-laws provide that the Trust 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.
G Other-Investment transactions are accounted for on a trade date basis.
H 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.
I Interim Financial Statements-The interim financial statements relating to June 30, 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 Fund'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
It is the present policy of the Fund to make quarterly distributions of all or substantially all of its net investment income and to distribute annually all or substantially all of its net realized capital gains (reduced by available capital loss carryforwards from prior years). Distributions to shareholders are recorded on the ex-dividend date. Shareholders may reinvest income and capital gain distributions in additional shares of the Fund at the net asset value as of the ex-dividend date or, at the election of the shareholder, receive distributions in cash. 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.
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 investment adviser fee is computed at an annual rate as a percentage of the Fund's average daily net assets that are not invested in other investment companies for which EVM or its affiliates serve as investment adviser and receive an advisory fee as follows and is payable monthly:
Average Daily Net Assets Annual Fee Rate
Up to $500 million 0.5575%
$500 million but less than $1 billion 0.4950%
$1 billion but less than $1.5 billion 0.4325%
$1.5 billion but less than $7 billion 0.3700%
$7 billion but less than $10 billion 0.3575%
$10 billion but less than $15 billion 0.3450%
$15 billion but less than $20 billion 0.3325%
$20 billion but less than $25 billion 0.3225%
$25 billion but less than $30 billion 0.3125%
$30 billion but less than $35 billion 0.3020%
$35 billion but less than $45 billion 0.2970%
$45 billion and over 0.2920%
For the six months ended June 30, 2026, the Fund incurred no investment adviser fee on such assets. To the extent the Fund's assets are invested in the Portfolio, the Fund is allocated its share of the Portfolio's investment adviser fee. The Portfolio has engaged Boston Management and Research (BMR) to render investment advisory services. See Note 2 of the Portfolio's Notes to Financial Statements which are included elsewhere in this report. EVM also serves as the administrator to the Fund, but receives no compensation.
EVM provides sub-transfer agency and related services to the Fund pursuant to a Sub-Transfer Agency Support Services Agreement. For the six months ended June 30, 2026, EVM earned $37,486 from the Fund pursuant to such agreement, which is included in transfer and dividend disbursing agent fees on the Statement of Operations.
Trustees and officers of the Fund who are members of EVM's or BMR's organizations receive remuneration for their services to the Fund out of the investment adviser fee. Certain officers and Trustees of the Fund and the Portfolio are officers of the above organizations.
4 Investment Transactions
For the six months ended June 30, 2026, increases and decreases in the Fund's investment in the Portfolio aggregated $0 and $42,716,283, respectively.
Decreases in the Fund's investment in the Portfolio include distributions of securities as the result of redemptions in-kind of $37,214,764.

Tax-Managed Growth Portfolio

Notes to Financial Statements (Unaudited)
1 Significant Accounting Policies
Tax-Managed Growth Portfolio (the Portfolio) is a Massachusetts business trust registered under the Investment Company Act of 1940, as amended (the 1940 Act), as a diversified, open-end management investment company. The Portfolio's investment objective is to achieve long-term, after-tax returns for interest holders through investing in a diversified portfolio of equity securities. The Declaration of Trust permits the Trustees to issue interests in the Portfolio. At June 30, 2026, Eaton Vance Tax-Managed Growth Fund 1.0, Eaton Vance Tax-Managed Growth Fund 1.1, Eaton Vance Tax-Managed Growth Fund 1.2 and Eaton Vance Tax-Managed Equity Asset Allocation Fund held an interest of 24.4%, 44.9%, 26.3%, and 4.4% respectively, in the Portfolio.
The following is a summary of significant accounting policies of the Portfolio. The policies are in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP). The Portfolio is an investment company and follows accounting and reporting guidance in the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946 "Financial Services - Investment Companies."
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 Portfolio'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 Portfolio'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 Portfolio 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 Portfolio is informed of the ex-dividend date. Withholding taxes on foreign dividends and capital gains have been provided for in accordance with the understanding of the applicable countries' tax rules and rates. As a result of several court cases in certain countries across the European Union (EU), the Portfolio filed additional tax reclaims for previously withheld taxes on dividends earned in those countries. Income recognized, if any, for EU reclaims and interest thereon is reflected as other income in the Consolidated Statement of Operations, and any related receivable, if any, is reflected as European Union tax reclaims receivable in the Consolidated Statement of Assets and Liabilities. Any fees associated with these filings are reflected in miscellaneous expenses in the Consolidated Statement of Operations. When uncertainty exists as to the ultimate resolution of these proceedings, the likelihood of receipt of these EU reclaims, and the potential timing of payment, no amounts are reflected in the financial statements. For U.S. income tax purposes, EU reclaims received by the Portfolio, if any, may reduce the amount of foreign taxes Fund shareholders can use as tax deductions or credits on their income tax returns. In the event that EU reclaims received by the Portfolio during a fiscal year exceed foreign withholding taxes paid by the Portfolio, and the Portfolio previously passed through to its shareholders foreign taxes incurred by the Portfolio to be used as a credit or deduction on a shareholder's income tax return, the Portfolio may be required to enter into a closing agreement with the Internal Revenue Service in order to pay the associated tax liability on behalf of the Fund's shareholders.

Tax-Managed Growth Portfolio
June 30, 2026
Notes to Financial Statements (Unaudited) - continued
D Federal and Other Taxes-The Portfolio has elected to be treated as a partnership for federal tax purposes. No provision is made by the Portfolio for federal or state taxes on any taxable income of the Portfolio because each investor in the Portfolio is ultimately responsible for the payment of any taxes on its share of taxable income. Since at least one of the Portfolio's investors is a regulated investment company that invests all or substantially all of its assets in the Portfolio, the Portfolio normally must satisfy the applicable source of income and diversification requirements (under the Internal Revenue Code) in order for its investors to satisfy them. The Portfolio will allocate, at least annually among its investors, each investor's distributive share of the Portfolio's net investment income, net realized capital gains and losses and any other items of income, gain, loss, deduction or credit.
As of June 30, 2026, the Portfolio had no uncertain tax positions that would require financial statement recognition, de-recognition, or disclosure. The Portfolio 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.
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 Portfolio'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 Portfolio. Under Massachusetts law, if certain conditions prevail, interestholders in the Portfolio could be deemed to have personal liability for the obligations of the Portfolio. However, the Portfolio's Declaration of Trust contains an express disclaimer of liability on the part of Portfolio interestholders. Additionally, in the normal course of business, the Portfolio enters into agreements with service providers that may contain indemnification clauses. The Portfolio's maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Portfolio that have not yet occurred.
H Written Options-Upon the writing of a call or a put option, the premium received by the Portfolio 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 Portfolio'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 Portfolio 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 Portfolio. The Portfolio, 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 Portfolio 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 Portfolio 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 Portfolio'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 Portfolio operates as a single reportable segment, an investment company whose investment objective(s) is included in Note 1. The Portfolio's President acts as the Portfolio's Chief Operating Decision Maker (CODM), who is responsible for assessing the performance of the Portfolio's single segment and deciding how to allocate the segment's resources. To perform this function, the CODM reviews the information in the Portfolio's financial statements.
K Interim Financial Statements-The interim financial statements relating to June 30, 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 Portfolio's management, reflect all adjustments, consisting only of normal recurring adjustments, necessary for the fair presentation of the financial statements.

The investment adviser fee is earned by Boston Management and Research (BMR) an indirect, wholly-owned subsidiary of Morgan Stanley, as compensation for investment advisory services rendered to the Portfolio. The investment adviser fee is based upon an annual rate of the Portfolio's average daily net assets as follows and is payable monthly:
Average Daily Net Assets Annual Fee Rate
Up to $500 million 0.5575%
$500 million but less than $1 billion 0.4950%
$1 billion but less than $1.5 billion 0.4325%
$1.5 billion but less than $7 billion 0.3700%
$7 billion but less than $10 billion 0.3575%
$10 billion but less than $15 billion 0.3450%
$15 billion but less than $20 billion 0.3325%
$20 billion but less than $25 billion 0.3225%
$25 billion but less than $30 billion 0.3125%
$30 billion but less than $35 billion 0.3020%
$35 billion but less than $45 billion 0.2970%
$45 billion and over 0.2920%
For the six months ended June 30, 2026, the Portfolio's investment adviser fee amounted to $13,212,259 or 0.40% (annualized) of the Portfolio's average daily net assets. The Portfolio 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 Portfolio is reduced by an amount equal to its pro rata share of the advisory and administration fees paid by the Portfolio due to its investment in the Liquidity Fund. For the six months ended June 30, 2026, the investment adviser fee paid was reduced by $23,988 relating to the Portfolio's investment in the Liquidity Fund.
BMR has agreed to waive its advisory fee and/or reimburse the Portfolio's operating expenses to the extent that total annual operating expenses (excluding expenses such as brokerage commissions, borrowing costs, taxes or litigation expenses, indemnification expenses, and other expenses not incurred in the ordinary course of the Portfolio's business) exceed 0.43% of Portfolio's average daily net assets. The expense reimbursement with BMR terminated on January 14, 2026. Pursuant to this agreement, no operating expenses were waived and/or reimbursed for the six months ended June 30, 2026.
Officers and Trustees of the Portfolio who are members of Eaton Vance Management's (EVM) or BMR's organizations receive remuneration for their services to the Portfolio out of the investment adviser fee. Trustees of the Portfolio who are not affiliated with the investment adviser 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 Portfolio are officers of the above organizations.
3 Purchases and Sales of Investments
Purchases and sales of investments, other than short-term obligations, aggregated $731,189,142 and $796,321,148, respectively, for the six months ended June 30, 2026. In addition, investments having an aggregate market value of $93,678,397 were distributed in payment for capital withdrawals during the six months ended June 30, 2026.
4 Federal Income Tax Basis of Investments
The cost and unrealized appreciation (depreciation) of investments of the Portfolio, including open derivative contracts, at June 30, 2026, as determined on a federal income tax basis, were as follows:
Aggregate cost $1,825,300,189

5 Line of Credit
The Portfolio participates with other portfolios and funds managed by EVM and its affiliates in a $650 million unsecured revolving line of credit agreement with a group of banks, which is in effect through October 20, 2026. Borrowings are made by the Portfolio solely for temporary purposes related to redemptions and other short-term cash needs. Interest is charged to the Portfolio based on its borrowings generally at an amount above either the Secured Overnight Financing Rate (SOFR) or Federal Funds rate. In addition, a fee computed at an annual rate of 0.15% on the daily unused portion of the line of credit is allocated among the participating portfolios and funds at the end of each quarter. In connection with the renewal of the agreement in October 2025, an arrangement fee totaling $150,000 was incurred that was allocated to the participating portfolios and funds. Because the line of credit is not available exclusively to the Portfolio, it may be unable to borrow some or all of its requested amounts at any particular time. The Portfolio did not have any significant borrowings or allocated fees during the six months ended June 30, 2026.
6 Financial Instruments
The Portfolio 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 Portfolio 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. At June 30, 2025, the portfolio had sufficient cash and/or securities to cover commitments under these contracts.
The Portfolio is subject to equity price risk in the normal course of pursuing its investment objective. During the six months ended June 30, 2026, the Portfolio entered into purchased and written option contracts as a substitute for purchasing or selling securities.
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 risk June 30, 2026 was as follows:
Fair Value
Derivative Asset Derivative(1) Liability Derivative(2)
Purchased options $4,684,700 $ -
Written options  - (8,298,030)
Total $4,684,700 $(8,298,030)
(1) Statement of Assets and Liabilities location: Unaffiliated investments, at value.
(2) Statement of Assets and Liabilities location: Written options outstanding, at value.
The effect of derivative instruments (not considered to be hedging instruments for accounting disclosure purposes) on the Statement of Operations and whose primary underlying risk exposure is equity price risk for the six months ended June 30, 2026 was as follows:
Derivative Realized Gain (Loss)
on Derivatives Recognized

Appreciation (Depreciation) on
Derivatives Recognized in Income(2)
Purchased options $ - $(247,193)
Written options 226,307 634,713

(1) Statement of Operations location: Net realized gain (loss) - Investment transactions and Written options, respectively.
(2) Statement of Operations location: Change in unrealized appreciation (depreciation) - Investments and Written options, respectively.
The average number of purchased and written options contracts outstanding during the six months ended June 30, 2026, which is indicative of the volume of these derivative types, were approximately 451 and 1,576 contracts, respectively.

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 June 30, 2026, the hierarchy of inputs used in valuing the Portfolio'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 $6,980,909,229* $     - $     - $6,980,909,229

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 the policies and practices of each fund's adviser and sub-adviser with respect to trading, including their processes for seeking best execution of portfolio transactions;
• Information about the allocation of brokerage transactions and the benefits, if any, received by the adviser and sub-adviser to each fund as a result of brokerage allocation, including, as applicable, information concerning the acquisition of research through client commission arrangements and policies with respect to "soft dollars";

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 agreement between Eaton Vance Tax-Managed Growth Fund 1.0 (the "Fund") and Eaton Vance Management ("EVM"), as well as the investment advisory agreement between Tax-Managed Growth Portfolio (the "Portfolio"), the portfolio in which the Fund invests, and Boston Management and Research ("BMR") (EVM, with respect to the Fund, and BMR, with

respect to the Portfolio, are each referred to herein as the "Adviser"), including their respective fee structures, are in the interests of shareholders and, therefore, recommended to the Board approval of each 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 agreements for the Fund and the Portfolio (together, the "investment advisory agreements").
Nature, Extent and Quality of Services
In considering whether to approve the investment advisory agreements for the Fund and the Portfolio, the Board evaluated the nature, extent and quality of services provided to the Fund and to the Portfolio by the applicable Adviser.
The Board considered each Adviser's management capabilities and investment processes in light of the types of investments held by the Fund and the Portfolio, including the education and experience of the investment professionals who provide services to the Fund and the Portfolio. The Board specifically noted that each Adviser has devoted extensive resources to in-house equity research and also draws upon independent research available from third-party sources. The Board considered the experience of each Adviser's investment professionals in managing funds that seek to maximize after-tax returns. The Board also took into account the resources dedicated to portfolio management and other services, the compensation methods of each 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 and the Portfolio, 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 and the Portfolio, including the provision of administrative services. The Board also considered the business-related and other risks to which each Adviser or its affiliates may be subject in managing the Fund and the Portfolio.
The Board noted that, under the terms of the investment advisory agreement of the Fund, EVM may invest assets of the Fund directly in securities, for which it would receive a fee, or in the Portfolio, for which it receives no separate fee but for which BMR receives an advisory fee from the Portfolio. The Board considered the potential benefits to the Fund of the ability to make direct investments, such as an improved ability to manage the Fund's general market exposures, either by investing in specific securities or through the use of certain derivatives.
The Board considered the compliance programs of each 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 each 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 EVM and its affiliates, including transfer agency and accounting services.
After consideration of the foregoing factors, among others, the Board concluded that the nature, extent and quality of services provided by each Adviser, taken as a whole, are appropriate and consistent with the terms of the applicable investment advisory 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 an appropriate benchmark index. 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 higher 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 lower than its primary performance benchmark index for the three-year period. The Board concluded that the performance of the Fund was satisfactory.
Management Fees and Expenses
The Board considered contractual fee rates payable by the Portfolio and 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 factors that had an impact on 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 each 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 each Adviser and relevant affiliates thereof in providing investment advisory and administrative services to the Fund, to the Portfolio 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 each 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 each Adviser and its affiliates are not excessive.

Board of Trustees' Contract Approval - continued
The Board also considered direct and indirect fall-out benefits received by each Adviser and its affiliates in connection with their respective relationships with the Fund, the Portfolio 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 applicable Adviser and its affiliates, on the one hand, and the Fund and the Portfolio, on the other hand, can expect to realize benefits from economies of scale as the assets of the Fund and the Portfolio 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 concluded that the structure of the advisory fees, which include breakpoints at several asset levels, will allow the Fund and the Portfolio to continue to benefit from any economies of scale in the future.
