*	In U.S. dollars unless otherwise indicated.
⁽¹⁾	Security exempt from registration under Rule 144A of the Securities Act of 1933, as amended. These securities may be sold in certain transactions in reliance on an exemption from registration (normally to qualified institutional buyers). At October 31, 2023, the aggregate value of these securities is $816,345,128 or 74.8% of the Portfolio's net assets.
⁽²⁾	Variable rate security. The stated interest rate represents the rate in effect at October 31, 2023.
⁽³⁾	Non-income producing security.

⁽⁴⁾	For fair value measurement disclosure purposes, security is categorized as Level 3 (see Note 9).
⁽⁵⁾	Restricted security.
⁽⁶⁾	Perpetual security with no stated maturity date but may be subject to calls by the issuer.
⁽⁷⁾	Security converts to variable rate after the indicated fixed-rate coupon period.
⁽⁸⁾	Issuer is in default with respect to interest and/or principal payments.
⁽⁹⁾	Security exempt from registration under Regulation S of the Securities Act of 1933, as amended, which exempts from registration securities offered and sold outside the United States. Security may not be offered or sold in the United States except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act of 1933, as amended. At October 31, 2023, the aggregate value of these securities is $22,881,035 or 2.1% of the Portfolio's net assets.
⁽¹⁰⁾	Represents a payment-in-kind security which may pay interest in additional principal at the issuer’s discretion.
⁽¹¹⁾	Senior floating-rate loans (Senior Loans) often require prepayments from excess cash flows or permit the borrowers to repay at their election. The degree to which borrowers repay, whether as a contractual requirement or at their election, cannot be predicted with accuracy. As a result, the actual remaining maturity may be substantially less than the stated maturities shown. However, Senior Loans will typically have an expected average life of approximately two to four years. Senior Loans typically have rates of interest which are redetermined periodically by reference to a base lending rate, plus a spread. These base lending rates are primarily the Secured Overnight Financing Rate (“SOFR”) (or the London Interbank Offered Rate (“LIBOR”) for those loans whose rates reset prior to the discontinuance of LIBOR on June 30, 2023) and secondarily, the prime rate offered by one or more major United States banks (the “Prime Rate”). Base lending rates may be subject to a floor, or minimum rate. Rates for SOFR are generally 1 or 3-month tenors and may also be subject to a credit spread adjustment. Senior Loans are generally subject to contractual restrictions that must be satisfied before they can be bought or sold.

1 Significant Accounting Policies

High Income Opportunities 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 provide a high level of current income. The Portfolio also seeks growth of capital as a secondary investment objective. The Declaration of Trust permits the Trustees to issue interests in the Portfolio. At October 31, 2023, Eaton Vance High Income Opportunities Fund and Eaton Vance Floating-Rate & High Income Fund held an interest of 77.2% and 13.9%, 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.

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

Senior Floating-Rate Loans. Interests in senior floating-rate loans (Senior Loans) are valued generally at the average mean of bid and ask quotations obtained from a third party pricing service. Senior Loans, for which a valuation is not available or deemed unreliable, are fair valued by the investment adviser utilizing one or more of the valuation techniques described below to assess the likelihood that the borrower will make a full repayment of the loan underlying such Senior Loan. If the investment adviser believes that there is a reasonable likelihood of full repayment, the investment adviser will determine fair value using a matrix pricing approach that considers the yield on the Senior Loan relative to yields on other Senior Loans issued by companies of comparable credit quality. If the investment adviser believes there is not a reasonable likelihood of full repayment, the investment adviser will determine fair value using analyses that include, but are not limited to: (i) a comparison of the value of the borrower's outstanding equity and debt to that of comparable public companies; (ii) a discounted cash flow analysis; or (iii) when the investment adviser believes it is likely that a borrower will be liquidated or sold, an analysis of the terms of such liquidation or sale. In certain cases, the investment adviser will use a combination of analytical methods to determine fair value, such as when only a portion of a borrower's assets are likely to be sold. In conducting its assessment and analyses for purposes of determining fair value of a Senior Loan, the investment adviser will use its discretion and judgment in considering and appraising relevant factors. Junior Loans (i.e., subordinated loans and second lien loans) are valued in the same manner as Senior Loans.

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 or, in the case of preferred equity securities that are not listed or traded in the over-the-counter market, by a third party pricing service that uses various techniques that consider factors including, but not limited to, prices or yields of securities with similar characteristics, benchmark yields, broker/dealer quotes, quotes of underlying common stock, issuer spreads, as well as industry and economic events.

Derivatives. Forward foreign currency exchange contracts are generally valued at the mean of the average bid and average ask prices that are reported by currency dealers to a third party pricing service at the valuation time. Such third party pricing service valuations are supplied for specific settlement periods and the Portfolio’s forward foreign currency exchange contracts are valued at an interpolated rate between the closest preceding and subsequent settlement period reported by the third party pricing service.

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.

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—Interest income is recorded on the basis of interest accrued, adjusted for amortization of premium or accretion of discount. Fees associated with loan amendments are recognized immediately. Dividend income is recorded on the ex-dividend date for dividends received in cash and/or securities. Withholding taxes on foreign dividends have been provided for in accordance with the Portfolio’s understanding of the applicable countries’ tax rules and rates. Distributions from investment companies are recorded as dividend income, capital gains or return of capital based on the nature of the distribution.

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 October 31, 2023, 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 Forward Foreign Currency Exchange Contracts—The Portfolio may enter into forward foreign currency exchange contracts for the purchase or sale of a specific foreign currency at a fixed price on a future date. The forward foreign currency exchange contracts are adjusted by the daily exchange rate of the underlying currency and any gains or losses are recorded as unrealized until such time as the contracts have been closed. Risks may arise upon entering these contracts from the potential inability of counterparties to meet the terms of their contracts and from movements in the value of a foreign currency relative to the U.S. dollar.

I Repurchase Agreements—A repurchase agreement is the purchase by the Portfolio of securities from a counterparty in exchange for cash that is coupled with an agreement to resell those securities to the counterparty at a specified date and price. When a repurchase agreement is entered, the Portfolio typically receives securities with a value that equals or exceeds the repurchase price, including any accrued interest earned on the agreement. The value of such securities will be marked-to-market daily, and cash or additional securities will be exchanged between the parties as needed. Except in the case of a repurchase agreement entered to settle a short sale, the value of the securities delivered to the Portfolio will be at least equal to 90% of the repurchase price during the term of the repurchase agreement. The terms of a repurchase agreement entered to settle a short sale may provide that the cash purchase price paid by the Portfolio is more than the value of purchased securities that effectively collateralize the repurchase price payable by the counterparty. In the event of insolvency of the counterparty to a repurchase agreement, recovery of the repurchase price owed to the Portfolio may be delayed. Such an insolvency also may result in a loss to the extent that the value of the purchased securities decreases during the delay or that value has otherwise not been maintained at an amount at least equal to the repurchase price.

J Securities Sold Short—A short sale is a transaction in which the Portfolio sells a security it does not own in anticipation of a decline in the market value of that security. To complete such a transaction, the Portfolio must borrow the security to make delivery to the buyer with an obligation to replace such

Table of Contents

High Income Opportunities Portfolio

Notes to Financial Statements — continued

borrowed security at a later date. Until the security is replaced, the Portfolio is required to repay the lender any dividends or interest, which accrue during the period of the loan. The proceeds received from a short sale are recorded as a liability and the Portfolio records an unrealized gain or loss to the extent of the difference between the proceeds received and the value of the open short position on the day of determination. A gain, limited to the price at which the Portfolio sold the security short, or a loss, potentially unlimited as there is no upward limit on the price of a security, is recorded when the short position is terminated. Interest and dividends payable on securities sold short are recorded as an expense.

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 investment adviser fee is based upon a percentage of total daily net assets plus a percentage of total daily gross income as follows and is payable monthly:

Total Daily Net Assets	Annual Asset Rate	Daily Income Rate
Up to $500 million	0.300%	3.000%
$500 million but less than $1 billion	0.275%	2.750%
$1 billion but less than $1.5 billion	0.250%	2.500%
$1.5 billion but less than $2 billion	0.225%	2.250%
$2 billion but less than $3 billion	0.200%	2.000%
$3 billion and over	0.175%	1.750%

For the year ended October 31, 2023, the Portfolio’s investment adviser fee amounted to $5,153,891 or 0.48% of the Portfolio's average daily net assets. Pursuant to an investment sub-advisory agreement, BMR has delegated a portion of the investment management of the Portfolio to Eaton Vance Advisers International Ltd. (EVAIL), an affiliate of BMR. BMR pays EVAIL a portion of its investment adviser fee for sub-advisory services provided to the Portfolio. 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 year ended October 31, 2023, the investment adviser fee paid was reduced by $66,281 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 and including maturities, paydowns and principal repayments on Senior Loans, aggregated $398,571,309 and $296,776,471, respectively, for the year ended October 31, 2023.

4 Federal Income Tax Basis of Investments

The cost and unrealized appreciation (depreciation) of investments, including open derivative contracts, of the Portfolio at October 31, 2023, as determined on a federal income tax basis, were as follows:

Aggregate cost	$1,184,986,070
Gross unrealized appreciation	$ 8,453,602
Gross unrealized depreciation	(120,063,818)
Net unrealized depreciation	$ (111,610,216)

5 Restricted Securities

At October 31, 2023, the Portfolio owned the following securities (representing 0.5% of net assets) which were restricted as to public resale and not registered under the Securities Act of 1933 (excluding Rule 144A securities). The Portfolio has various registration rights (exercisable under a variety of circumstances) with respect to these securities. The value of these securities is determined based on valuations provided by brokers when available, or if not available, they are valued at fair value using methods determined in good faith by or at the direction of the Trustees' valuation designee.

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 forward foreign currency exchange contracts 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. A summary of obligations under these financial instruments at October 31, 2023 is included in the Portfolio of Investments. At October 31, 2023, the Portfolio had sufficient cash and/or securities to cover commitments under these contracts.

The Portfolio is subject to foreign exchange risk in the normal course of pursuing its investment objectives. Because the Portfolio holds foreign currency denominated investments, the value of these investments and related receivables and payables may change due to future changes in foreign currency exchange rates. To hedge against this risk, the Portfolio enters into forward foreign currency exchange contracts.

The Portfolio enters into forward foreign currency exchange contracts that may contain provisions whereby the counterparty may terminate the contract under certain conditions, including but not limited to a decline in the Portfolio’s net assets below a certain level over a certain period of time, which would trigger a payment by the Portfolio for those derivatives in a liability position. At October 31, 2023, the fair value of derivatives with credit-related contingent features in a net liability position was $3,673. At October 31, 2023, there were no assets pledged by the Portfolio for such liability.

The over-the-counter (OTC) derivatives in which the Portfolio invests are subject to the risk that the counterparty to the contract fails to perform its obligations under the contract. To mitigate this risk, the Portfolio has entered into an International Swaps and Derivatives Association, Inc. Master Agreement (“ISDA Master Agreement”) or similar agreement with substantially all its derivative counterparties. An ISDA Master Agreement is a bilateral agreement between the Portfolio and a counterparty that governs certain OTC derivatives and typically contains, among other things, set-off provisions in the event of a default and/or termination event as defined under the relevant ISDA Master Agreement. Under an ISDA Master Agreement, the Portfolio may, under certain circumstances, offset with the counterparty certain derivative financial instruments’ payables and/or receivables with collateral held and/or posted and create one single net payment. The provisions of the ISDA Master Agreement typically permit a single net payment in the event of default including the bankruptcy or insolvency of the counterparty. However, bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against the right of offset in bankruptcy or insolvency. Certain ISDA Master Agreements allow counterparties to OTC derivatives to terminate derivative contracts prior to maturity in the event the Portfolio’s net assets decline by a stated percentage or the Portfolio fails to meet the terms of its ISDA Master Agreements, which would cause the counterparty to accelerate payment by the Portfolio of any net liability owed to it.

The collateral requirements for derivatives traded under an ISDA Master Agreement are governed by a Credit Support Annex to the ISDA Master Agreement. Collateral requirements are determined at the close of business each day and are typically based on changes in market values for each transaction under an ISDA Master Agreement and netted into one amount for such agreement. Generally, the amount of collateral due from or to a counterparty is subject to a

minimum transfer threshold amount before a transfer is required, which may vary by counterparty. Collateral pledged for the benefit of the Portfolio and/or counterparty is held in segregated accounts by the Portfolio’s custodian and cannot be sold, re-pledged, assigned or otherwise used while pledged. The portion of such collateral representing cash, if any, is reflected as deposits for derivatives collateral and, in the case of cash pledged by a counterparty for the benefit of the Portfolio, a corresponding liability on the Statement of Assets and Liabilities. Securities pledged by the Portfolio as collateral, if any, are identified as such in the Portfolio of Investments.

The fair value of open derivative instruments (not considered to be hedging instruments for accounting disclosure purposes) and whose primary underlying risk exposure is foreign exchange risk at October 31, 2023 was as follows:

	Fair Value
Derivative	Asset Derivative	Liability Derivative

⁽¹⁾	Statement of Assets and Liabilities location: Receivable for forward foreign currency exchange contracts.
⁽²⁾	Statement of Assets and Liabilities location: Payable for open forward foreign currency exchange contracts.

The Portfolio's derivative assets and liabilities at fair value by type, which are reported gross in the Statement of Assets and Liabilities, are presented in the table above. The following tables present the Portfolio's derivative assets and liabilities by counterparty, net of amounts available for offset under a master netting agreement and net of the related collateral received by the Portfolio for such assets and pledged by the Portfolio for such liabilities as of October 31, 2023.

The average notional amount of forward foreign currency exchange contracts (based on the absolute value of notional amounts of currency purchased and currency sold) outstanding during the year ended October 31, 2023, which is indicative of the volume of this derivative type, was approximately $20,831,000.

7 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 22, 2024. In connection with the renewal of the agreement on October 24, 2023, the borrowing limit was decreased from $725 million. 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 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 2023, 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 year ended October 31, 2023.

8 Affiliated Investments

At October 31, 2023, the value of the Portfolio's investment in funds that may be deemed to be affiliated was $37,843,239, which represents 3.5% of the Portfolio's net assets. Transactions in such investments by the Portfolio for the year ended October 31, 2023 were as follows:

Name	Value, beginning of period	Purchases	Sales proceeds	Net realized gain (loss)	Change in unrealized appreciation (depreciation)	Value, end of period	Dividend income	Shares, end of period
Short-Term Investments
Liquidity Fund	$37,909,716	$420,330,355	$(420,396,832)	$ —	$ —	$37,843,239	$2,059,660	37,843,239

9 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 October 31, 2023, 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
Asset-Backed Securities	$ —	$ 18,800,846	$ —	$ 18,800,846
Common Stocks	3,878,904	—	1,380,162	5,259,066
Convertible Bonds	—	8,820,395	—	8,820,395
Corporate Bonds	—	937,978,972	—	937,978,972
Preferred Stocks	3,932,030	—	—	3,932,030
Senior Floating-Rate Loans	—	56,293,184	—	56,293,184
Miscellaneous	—	45,180	4,402,942	4,448,122

10 Risks and Uncertainties

Credit Risk

The Portfolio primarily invests in lower rated and comparable quality unrated high yield securities. These investments have different risks than investments in debt securities rated investment grade. Risk of loss upon default by the borrower is significantly greater with respect to such debt than with other debt securities because these securities are generally unsecured and are more sensitive to adverse economic conditions, such as recession or increasing interest rates, than are investment grade issuers.

Report of Independent Registered Public Accounting Firm

To the Trustees and Investors of High Income Opportunities Portfolio:

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying statement of assets and liabilities of High Income Opportunities Portfolio (the “Portfolio"), including the portfolio of investments, as of October 31, 2023, the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, the financial highlights for each of the five years in the period then ended, and the related notes. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Portfolio as of October 31, 2023, and the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements and financial highlights are the responsibility of the Portfolio’s management. Our responsibility is to express an opinion on the Portfolio’s financial statements and financial highlights based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Portfolio in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement, whether due to error or fraud. The Portfolio is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Portfolio’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. Our procedures included confirmation of securities and senior loans owned as of October 31, 2023, by correspondence with the custodian, brokers, and agent banks; when replies were not received from brokers and agent banks, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

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 8, 2023, 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 exclusively comprised of 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 formal meetings held between April and June 2023, as well as certain additional information provided in response to specific requests from the Independent Trustees as members of the Contract Review Committee.

During the various meetings of the Board and its committees over the course of the year leading up to the June 8, 2023 meeting, the Board received information from portfolio managers and other investment professionals of the advisers 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 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 Eaton Vance Management, Boston Management and Research and fund sub-advisers, with respect to such matters. In addition to the formal meetings of the Board and its committees, the Independent Trustees held regular teleconferences to discuss, among other topics, matters relating to the continuation of investment advisory agreements and sub-advisory agreements.

The Contract Review Committee was advised throughout the contract review process by Goodwin Procter LLP, independent legal counsel for the Independent Trustees. The members of the Contract Review Committee, 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 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 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 High Income Opportunities Fund (the “Fund”) and Eaton Vance Management (“EVM”), as well as the investment advisory agreement between High Income Opportunities 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”), and the sub-advisory agreement between EVM and Eaton Vance Advisers International

Ltd. (the “Sub-adviser”), an affiliate of the Advisers, with respect to the Fund, and the sub-advisory agreement between BMR and the Sub-adviser, with respect to the Portfolio, 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”) and the sub-advisory agreements for the Fund and the Portfolio (together, the “sub-advisory agreements”).

Nature, Extent and Quality of Services

In considering whether to approve the investment advisory agreements and sub-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 and the Sub-adviser, respectively.

The Board considered each Adviser’s and the Sub-adviser’s management capabilities and investment processes in light of the types of investments held by the Fund and the Portfolio, including the education, experience and number of investment professionals and other personnel who provide portfolio management, investment research, and similar services to the Fund and the Portfolio. Regarding each Adviser, the Board considered the Adviser’s responsibilities with respect to oversight of the Sub-adviser. The Board also considered the abilities and experience of each Adviser’s investment professionals in analyzing special considerations relevant to investing in high-yield debt. With respect to the Sub-adviser, the Board considered the abilities and experience of the Sub-adviser’s investment professionals in analyzing factors such as special considerations relevant to investing in global high yield debt and foreign markets. The Board considered the international investment capabilities of the Sub-adviser, which is based in London, and the benefits to the Fund and the Portfolio of having portfolio management services involving investments in international securities provided by investment professionals located abroad. 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 each 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, including the Sub-adviser. The Board considered compliance and reporting matters regarding, among other things, personal trading by investment professionals, disclosure of portfolio holdings, late trading, frequent trading, portfolio valuation, business continuity and the allocation of investment opportunities. The Board also considered the responses of each Adviser and its affiliates to requests in recent years from 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 and the Sub-adviser, taken as a whole, are appropriate and consistent with the terms of the applicable investment advisory agreement and the applicable sub-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 appropriate benchmark indices. 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, 2022. 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 primary and secondary benchmark indexes 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, 2022, as compared to those of comparable funds, before and after giving effect to any undertaking to waive fees or reimburse expenses. The Board also received and considered information about the services offered and the fee rates charged by the Adviser and/or Sub-adviser to other types of accounts with investment objectives and strategies that are substantially similar to and/or managed in a similar investment style as the Portfolio. In this regard, the Board received information about the differences in the nature and scope of services the Adviser and/or Sub-adviser provide to the Portfolio as compared to other types of accounts and the material differences in compliance, reporting and other legal burdens and risks to the Adviser and/or Sub-adviser as between the Portfolio and other types of accounts. The Board also considered factors that had an impact on the Fund’s total expense ratio relative to comparable funds.

Board of Trustees’ Contract Approval — continued

After considering the foregoing information, and in light of the nature, extent and quality of the services provided by each Adviser and the Sub-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, including the Sub-adviser, 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, including the Sub-adviser, are deemed not to be excessive.

The Board also considered direct or indirect fall-out benefits received by each Adviser and its affiliates, including the Sub-adviser, 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 or the Sub-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. The Board reviewed data summarizing the increases and decreases in the assets of the Fund and of all Eaton Vance Funds as a group over various time periods, and evaluated the extent to which the total expense ratio of the Fund and the profitability of each Adviser and its affiliates may have been affected by such increases or decreases. 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.

Liquidity Risk Management Program

The Fund has implemented a written liquidity risk management program (Program) and related procedures to manage its liquidity in accordance with Rule 22e-4 under the Investment Company Act of 1940, as amended (Liquidity Rule). The Liquidity Rule defines “liquidity risk” as the risk that a fund could not meet requests to redeem shares issued by the fund without significant dilution of the remaining investors’ interests in the fund. The Fund’s Board of Trustees/Directors has designated the investment adviser to serve as the administrator of the Program and the related procedures. The administrator has established a Liquidity Risk Management Oversight Committee (Committee) to perform the functions necessary to administer the Program. As part of the Program, the administrator is responsible for identifying illiquid investments and categorizing the relative liquidity of the Fund’s investments in accordance with the Liquidity Rule. Under the Program, the administrator assesses, manages, and periodically reviews the Fund’s liquidity risk, and is responsible for making certain reports to the Fund’s Board of Trustees/Directors and the Securities and Exchange Commission (SEC) regarding the liquidity of the Fund’s investments, and to notify the Board of Trustees/Directors and the SEC of certain liquidity events specified in the Liquidity Rule. The liquidity of the Fund’s portfolio investments is determined based on a number of factors including, but not limited to, relevant market, trading and investment-specific considerations under the Program.

At a meeting of the Fund’s Board of Trustees/Directors on June 7, 2023, the Committee provided a written report to the Fund’s Board of Trustees/
Directors pertaining to the operation, adequacy, and effectiveness of implementation of the Program, as well as the operation of the highly liquid investment minimum (if applicable) for the period January 1, 2022 through December 31, 2022 (Review Period). The Program operated effectively during the Review Period, supporting the administrator’s ability to assess, manage and monitor Fund liquidity risk, including during periods of market volatility and net redemptions. During the Review Period, the Fund met redemption requests on a timely basis.

There can be no assurance that the Program will achieve its objectives in the future. Please refer to the Fund’s prospectus for more information regarding the Fund’s exposure to liquidity risk and other principal risks to which an investment in the Fund may be subject.

IMPORTANT NOTICES

Delivery of Shareholder Documents. The Securities and Exchange Commission (SEC) permits funds to deliver only one copy of shareholder documents, including prospectuses, proxy statements and shareholder reports, to fund investors with multiple accounts at the same residential or post office box address. This practice is often called “householding” and it helps eliminate duplicate mailings to shareholders. Eaton Vance, or your financial intermediary, may household the mailing of your documents indefinitely unless you instruct Eaton Vance, or your financial intermediary, otherwise. If you would prefer that your Eaton Vance documents not be householded, please contact Eaton Vance at 1-800-262-1122, or contact your financial intermediary. Your instructions that householding not apply to delivery of your Eaton Vance documents will typically be effective within 30 days of receipt by Eaton Vance or your financial intermediary.

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

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

Tailored Shareholder Reports. Effective January 24, 2023, the SEC adopted rule and form amendments to require open-end mutual funds and ETFs to transmit concise and visually engaging streamlined annual and semiannual reports to shareholders that highlight key information. Other information, including financial statements, will no longer appear in a streamlined shareholder report but must be available online, delivered free of charge upon request, and filed on a semiannual basis on Form N-CSR. The rule and form amendments have a compliance date of July 24, 2024. At this time, management is evaluating the impact of these amendments on the shareholder reports for the Eaton Vance Funds.

The Pre-Approval Policies establish a framework intended to assist the audit committee in the proper discharge of its pre-approval responsibilities. As a general matter, the Pre-Approval Policies (i) specify certain types of audit, audit-related, tax, and other services determined to be pre-approved by the audit committee; and (ii) delineate specific procedures governing the mechanics of the pre-approval process, including the approval and monitoring of audit and non-audit service fees. Unless a service is specifically pre-approved under the Pre-Approval Policies, it must be separately pre-approved by the Audit Committee.

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