1 Significant Accounting Policies

Stock 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 capital appreciation by investing in a diversified portfolio of equity securities. The Declaration of Trust permits the Trustees to issue interests in the Portfolio. At June 30, 2025, Eaton Vance Stock Fund and Eaton Vance Balanced Fund held an interest of 13.4% and 86.6%, 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.

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.**

**Foreign Currencies. Foreign 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.**

**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 Portfolio's understanding of the applicable countries' tax rules and rates.

D Federal 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, 2025, 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—Other assets and liabilities initially expressed in foreign currencies are translated each business day into U.S. dollars based upon current exchange rates. 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.

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 Segment Reporting—FASB Accounting Standards Update No. 2023-07, *Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures,* (ASU 2023-07), requires incremental disclosures related to a public entity's reportable segments. The Portfolio operates as a single reportable segment, an investment company whose investment objective(s) is included in Note 1. In connection with ASU 2023-07, 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.

I Interim Financial Statements—The interim financial statements relating to June 30, 2025 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.

2 Investment Adviser Fee and Other Transactions with Affiliates

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 fee is computed at an annual rate as a percentage of the Portfolio's average daily net assets as follows and is payable monthly:

---

| | |
|:---|:---|
| **Average Daily Net Assets** | &nbsp;&nbsp;&nbsp;&nbsp;**Annual Fee Rate** |
| Up to $500 million | &nbsp;&nbsp;&nbsp;&nbsp;0.600% |
| $500 million but less than $1 billion | &nbsp;&nbsp;&nbsp;&nbsp;0.575% |
| $1 billion but less than $2.5 billion | &nbsp;&nbsp;&nbsp;&nbsp;0.550% |
| $2.5 billion but less than $5 billion | &nbsp;&nbsp;&nbsp;&nbsp;0.530% |
| $5 billion and over | &nbsp;&nbsp;&nbsp;&nbsp;0.515% |

---

For the six months ended June 30, 2025, the Portfolio's investment adviser fee amounted to $2,125,359 or 0.59% (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, 2025, the investment adviser fee paid was reduced by $2,295 relating to the Portfolio's investment in the Liquidity Fund.

Trustees and officers of the Portfolio who are members of BMR's organization 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 organization.

3 Purchases and Sales of Investments

Purchases and sales of investments, other than short-term obligations, aggregated $160,476,834 and $185,978,261, respectively, for the six months ended June 30, 2025.

4 Federal Income Tax Basis of Investments

The cost and unrealized appreciation (depreciation) of investments of the Portfolio at June 30, 2025, as determined on a federal income tax basis, were as follows:

---

| | |
|:---|:---|
| **Aggregate cost** | &nbsp;&nbsp;**$413902956** |
| Gross unrealized appreciation | &nbsp;&nbsp;$356021004 |
| Gross unrealized depreciation | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1573732) |
| **Net unrealized appreciation** | &nbsp;&nbsp;**$354447272** |

---

5 Line of Credit

The Portfolio participates with other portfolios and funds managed by BMR and its affiliates in a $650 million unsecured revolving line of credit agreement with a group of banks, which is in effect through October 21, 2025. 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 2024, an arrangement fee of $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, 2025.

6 Affiliated Investments

At June 30, 2025, the value of the Portfolio's investment in funds that may be deemed to be affiliated was $1,847,148, which represents 0.2% of the Portfolio's net assets. Transactions in such investments by the Portfolio for the six months ended June 30, 2025 were as follows:

---

| | | | | | | | | |
|:---|:---|:---|:---|:---|:---|:---|:---|:---|
| **Name** | **Value,<br> beginning<br> of period** | **Purchases** | **Sales<br> proceeds** | **Net realized<br> gain (loss)** | **Change in<br> unrealized<br> appreciation<br> (depreciation)** | **Value, end<br> of period** | **Dividend<br> income** | **Shares,<br> end of period** |

7 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.

Eaton Vance

Stock Fund

June 30, 2025

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 12, 2025, 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 agreements<sup>1</sup> 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 2025, 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;

• A report from an independent data provider comparing the investment performance of each fund to the investment performance of comparable funds and, as applicable, benchmark indices, over various time periods;

• In certain instances, data regarding investment performance relative to customized groups of peer funds and blended indices identified by the adviser in consultation with the Portfolio Management Committee of the Board (a committee exclusively comprised of Independent Trustees);

• Comparative information concerning the fees charged and services provided by the adviser and sub-adviser to each fund in managing other accounts (which may include other funds, collective investment trusts and institutional accounts) with the same or substantially similar investment objective as the fund and with a significant overlap in holdings based on criteria set by the Board, if any;

• Profitability analyses on a fund-by-fund basis for the adviser and its affiliates and for each sub-adviser not affiliated with the adviser;

*Information about Portfolio Management and Trading*

• Descriptions of the investment management services provided to each fund, as well as each of the funds' investment strategies and policies;

• The procedures and processes used by the adviser to determine the value of fund assets, including, when necessary, the determination of "fair value" by the adviser in its role as each fund's valuation designee and actions taken to monitor and test the effectiveness of such procedures and processes;

• 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";

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 Stock Fund (the "Fund") and Eaton Vance Management ("EVM"), as well as the investment advisory agreement between Stock 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 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 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. 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, as well as the ability, in many cases, to exchange an investment among different funds without incurring additional sales charges.

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, 2024. 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 higher than its 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, 2024, 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.

The Board also considered direct or indirect fall-out benefits received by each Adviser and its affiliates in connection with their respective relationships with the Fund and the Portfolio, including the benefits of research services that may be available to each Adviser as a result of securities transactions effected for the Fund and the Portfolio and other investment advisory clients.

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.
