The adviser is registered with the CFTC as a commodity pool operator with respect to its management of the Fund. As the commodity pool operator of the Fund, the adviser has claimed relief under the Commodity Exchange Act from certain reporting and recordkeeping requirements. The adviser is also registered as a commodity trading advisor.

Past performance is no guarantee of future results. Returns are historical and are calculated by determining the percentage change in net asset value (NAV) or offering price (as applicable) with all distributions reinvested. Furthermore, returns do not reflect the deduction of taxes that shareholders may have to pay on Fund distributions or upon the redemption of Fund shares. Investment return and principal value will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. Performance for periods less than or equal to one year is cumulative. Performance is for the stated time period only; due to market volatility, current Fund performance may be lower or higher than the quoted return. For performance as of the most recent month-end, please refer to eatonvance.com.

¹	J.P. Morgan EMB (JEMB) Hard Currency/Local Currency 50-50 Index is a blended index comprised of 25% J.P. Morgan Emerging Markets Bond Index (EMBI) Global Diversified, 25% J.P. Morgan Corporate Emerging Markets Bond Index (CEMBI) Broad Diversified, and 50% J.P. Morgan Government Bond Index: Emerging Markets Global Diversified (JPM GBI-EM GD) (Unhedged). J.P.

Morgan Corporate Emerging Markets Bond Index (CEMBI) Broad Diversified is an unmanaged index of USD-denominated emerging market corporate bonds. J.P. Morgan Government Bond Index: Emerging Markets Global Diversified (JPM GBI-EM GD) (Unhedged) is an unmanaged index of local-currency bonds with maturities of more than one year issued by emerging markets governments. Information has been obtained from sources believed to be reliable but J.P. Morgan does not warrant its completeness or accuracy. The Index is used with permission. The Index may not be copied, used, or distributed without J.P. Morgan’s prior written approval. Copyright 2022, J.P. Morgan Chase & Co. All rights reserved. Unless otherwise stated, index returns do not reflect the effect of any applicable sales charges, commissions, expenses, taxes or leverage, as applicable. It is not possible to invest directly in an index.
²	Total Returns at net asset value (NAV) do not include applicable sales charges. If sales charges were deducted, the returns would be lower. Total Returns shown with maximum sales charge reflect the stated maximum sales charge. Unless otherwise stated, performance does not reflect the deduction of taxes on Fund distributions or redemptions of Fund shares. Performance prior to the inception date of a class may be linked to the performance of an older class of the Fund. This linked performance is adjusted for any applicable sales charge, but is not adjusted for class expense differences. If adjusted for such differences, the performance would be different. The performance of Class A and Class I is linked to Class R6. Performance since inception for an index, if presented, is the performance since the Fund’s or oldest share class’ inception, as applicable. Performance presented in the Financial Highlights included in the financial statements is not linked.
³	Source: Fund prospectus. The expense ratios for the current reporting period can be found in the Financial Highlights section of this report. Performance reflects expenses waived and/or reimbursed, if applicable. Without such waivers and/or reimbursements, performance would have been lower.

Fund Expenses

Example

As a Fund shareholder, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchases; and (2) ongoing costs, including management fees; distribution and/or service fees; and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of Fund investing and to compare these costs with the ongoing costs of investing in other mutual funds. The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (August 1, 2023 to January 31, 2024).

Actual Expenses

The first section of the table below provides information about actual account values and actual expenses. You may use the information in this section, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first section under the heading entitled “Expenses Paid During Period” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The second section of the table below provides information about hypothetical account values and hypothetical expenses based on the actual Fund expense ratio and an assumed rate of return of 5% per year (before expenses), which is not the actual Fund return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in your Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads). Therefore, the second section of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would be higher.

	Beginning Account Value (8/1/23)	Ending Account Value (1/31/24)	Expenses Paid During Period* (8/1/23 – 1/31/24)	Annualized Expense Ratio
Actual
Class A	$1,000.00	$1,042.20	$5.49	1.07%
Class I	$1,000.00	$1,043.50	$4.21	0.82%
Class R6	$1,000.00	$1,043.80	$3.75	0.73%

Hypothetical
(5% return per year before expenses)
Class A	$1,000.00	$1,019.76	$5.43	1.07%
Class I	$1,000.00	$1,021.01	$4.17	0.82%
Class R6	$1,000.00	$1,021.47	$3.71	0.73%

Expenses are equal to the Fund’s annualized expense ratio for the indicated Class, multiplied by the average account value over the period, multiplied by 184/366 (to reflect the one-half year period). The Example assumes that the $1,000 was invested at the net asset value per share determined at the close of business on July 31, 2023.

⁽⁹⁾	Issuer is in default with respect to interest and/or principal payments.
⁽¹⁰⁾	For fair value measurement disclosure purposes, security is categorized as Level 3 (see Note 11).
⁽¹¹⁾	Limited recourse note whose payments by the issuer are limited to amounts received by the issuer from the borrower pursuant to a loan agreement with the borrower.
⁽¹²⁾	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.

⁽¹³⁾	Step coupon security. Interest rate represents the rate in effect at January 31, 2024.
⁽¹⁴⁾	Weighted average fixed-rate coupon that changes/updates monthly. Rate shown is the rate at January 31, 2024.
⁽¹⁵⁾	Inflation-linked security whose principal is adjusted for inflation based on changes in a designated inflation index or inflation rate for the applicable country. Interest is calculated based on the inflation-adjusted principal.
⁽¹⁶⁾	Variable rate security. The stated interest rate represents the rate in effect at January 31, 2024.
⁽¹⁷⁾	Non-income producing security.
⁽¹⁸⁾	May be deemed to be an affiliated investment company. The rate shown is the annualized seven-day yield as of January 31, 2024.
⁽¹⁹⁾	Open repurchase agreement with no specific maturity date. Either party may terminate the agreement upon demand.
⁽²⁰⁾	Security (or a portion thereof) has been pledged to cover collateral requirements on open derivative contracts.

*	If the Fund is the seller of credit protection, the notional amount is the maximum potential amount of future payments the Fund could be required to make if a credit event, as defined in the credit default swap agreement, were to occur. At January 31, 2024, such maximum potential amount for all open credit default swaps in which the Fund is the seller was $33,072,000.
**	The contract annual fixed rate represents the fixed rate of interest received by the Fund (as a seller of protection) or paid by the Fund (as a buyer of protection) on the notional amount of the credit default swap contract.
***	Current market annual fixed rates, utilized in determining the net unrealized appreciation or depreciation as of period end, serve as an indicator of the market’s perception of the current status of the payment/performance risk associated with the credit derivative. The current market annual fixed rate of a particular reference entity reflects the cost, as quoted by the pricing vendor, of selling protection against default of that entity as of period end and may include upfront payments required to be made to enter into the agreement. The higher the fixed rate, the greater the market perceived risk of a credit event involving the reference entity. A rate identified as “Defaulted” indicates a credit event has occurred for the reference entity.
⁽¹⁾	Upfront payment is exchanged with the counterparty as a result of the standardized trading coupon.

1 Significant Accounting Policies

Eaton Vance Emerging Markets Debt Opportunities Fund (the Fund) is a non-diversified series of Eaton Vance Series Fund, Inc. (the Corporation). The Corporation is a Maryland corporation registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company. The Fund’s investment objective is total return. The Fund offers three classes of shares. Class A shares are generally sold subject to a sales charge imposed at time of purchase. Class I and Class R6 shares are sold at net asset value and are not subject to a sales charge. Each class represents a pro rata interest in the Fund, but votes separately on class-specific matters and (as noted below) is subject to different expenses. Realized and unrealized gains and losses and net investment income and losses, other than class-specific expenses, are allocated daily to each class of shares based on the relative net assets of each class to the total net assets of the Fund. Sub-accounting, recordkeeping and similar administrative fees payable to financial intermediaries, which are a component of transfer and dividend disbursing agent fees on the Statement of Operations, are not allocated to Class R6 shares. Each class of shares differs in its distribution plan and certain other class-specific expenses.

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.

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.

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 (including options on securities, indices and foreign currencies) 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. Futures contracts are valued at the closing settlement price established by the board of trade or exchange on which they are traded. 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 Fund’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. Non-deliverable bond forward contracts are generally valued based on the current price of the underlying bond as provided by a third party pricing service and current interest rates. Swaps and options on swaps (“swaptions”) are normally valued using valuations provided by a third party pricing service. Such pricing service valuations are based on the present value of fixed and projected floating rate cash flows over the term of the swap contract, and in the case of credit default swaps, based on credit spread quotations obtained from broker/dealers and expected default recovery rates determined by the pricing service using proprietary models. In the case of total return swaps, the pricing service valuations are based on the value of the underlying index or instrument and reference interest rate. Future cash flows on swaps are discounted to their present value using swap rates provided by electronic data services or by broker/dealers. Alternatively, swaptions may be valued at the valuation provided by a broker/dealer (usually the counterparty to the option), so determined using similar techniques as those employed by the 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 Directors have designated the Fund’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 Fund 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.

Emerging Markets Debt Opportunities Fund

January 31, 2024

Notes to Financial Statements (Unaudited) — continued

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. Inflation adjustments to the principal amount of inflation-adjusted bonds and notes are reflected as interest income. Deflation adjustments to the principal amount of an inflation-adjusted bond or note are reflected as reductions to interest income to the extent of interest income previously recorded on such bond or note. Dividend income is recorded on the ex-dividend date for dividends received in cash and/or securities. Withholding taxes on foreign interest and capital gains have been provided for in accordance with the Fund’s understanding of the applicable countries’ tax rules and rates.

D 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.

In addition to the requirements of the Internal Revenue Code, the Fund may also be subject to local taxes on the recognition of capital gains in certain countries. In determining the daily net asset value, the Fund estimates the accrual for such taxes, if any, based on the unrealized appreciation on certain portfolio securities and the related tax rates. Taxes attributable to unrealized appreciation are included in the change in unrealized appreciation (depreciation) on investments. Capital gains taxes on securities sold are included in net realized gain (loss) on investments.

As of January 31, 2024, 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.

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 Unfunded Loan Commitments—The Fund may enter into certain loan agreements all or a portion of which may be unfunded. The Fund is obligated to fund these commitments at the borrower's discretion. These commitments, if any, are disclosed in the accompanying Portfolio of Investments.

G 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.

H Indemnifications—The Corporation’s Articles of Incorporation provide that no Director or officer of the Corporation shall be liable, to the fullest extent permitted by Maryland law and the 1940 Act, to the Corporation or to its shareholders for money damages. 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.

I Futures Contracts—Upon entering into a futures contract, the Fund is required to deposit with the broker, either in cash or securities, an amount equal to a certain percentage of the contract amount (initial margin). Subsequent payments, known as variation margin, are made or received by the Fund each business day, depending on the daily fluctuations in the value of the underlying security, and are recorded as unrealized gains or losses by the Fund. Gains (losses) are realized upon the expiration or closing of the futures contracts. Should market conditions change unexpectedly, the Fund may not achieve the anticipated benefits of the futures contracts and may realize a loss. Futures contracts have minimal counterparty risk as they are exchange traded and the clearinghouse for the exchange is substituted as the counterparty, guaranteeing counterparty performance.

J Forward Foreign Currency Exchange and Non-Deliverable Bond Forward Contracts—The Fund 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. While forward foreign currency exchange contracts are privately negotiated agreements between the Fund and a counterparty, certain contracts may be “centrally cleared”, whereby all payments made or received by the Fund pursuant to the contract are with a central clearing party (CCP) rather than the original counterparty. The CCP guarantees the performance of the original parties to the contract. Upon entering into centrally cleared contracts, the Fund is required to deposit with the CCP, either in cash or securities, an amount of initial margin determined by the CCP, which is subject to adjustment. For centrally cleared contracts, the daily change in valuation is recorded as a receivable or payable for variation margin and settled in cash with the CCP daily. The Fund may also enter into non-deliverable bond forward contracts for the purchase or sale of a bond denominated in a non-deliverable foreign currency at a fixed price on a future date. For non-deliverable bond forward contracts, unrealized gains and losses, based on changes in the value of the contract, and realized gains and losses are accounted for as described above. Risks may arise upon entering these contracts

Notes to Financial Statements (Unaudited) — continued

from the potential inability of counterparties to meet the terms of their contracts and, in the case of forward foreign currency exchange contracts, from movements in the value of a foreign currency relative to the U.S. dollar. In the case of centrally cleared contracts, counterparty risk is minimal due to protections provided by the CCP.

K Purchased Options—Upon the purchase of a call or put option, the premium paid by the Fund 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 Fund’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 risk that the issuer or counterparty will fail to perform its contractual obligations.

L Written Options—Upon the writing of a call or a put option, the premium received by the Fund is included in the Statement of Assets and Liabilities 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 Fund’s policies on investment valuations discussed above. Premiums received from writing options that expire are treated as realized gains. Premiums received from writing options that 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. The Fund, as a writer of an option, may have no control over whether the underlying instrument may be sold (call) or purchased (put) and, as a result, bears the market risk of an unfavorable change in the price of the instrument underlying the written option. The Fund may also bear the risk of not being able to enter into a closing transaction if a liquid secondary market does not exist.

M Interest Rate Swaps—Swap contracts are privately negotiated agreements between the Fund and a counterparty. Certain swap contracts may be centrally cleared. Pursuant to interest rate swap agreements, the Fund either makes floating-rate payments to the counterparty (or CCP in the case of centrally cleared swaps) based on a benchmark interest rate in exchange for fixed-rate payments or the Fund makes fixed-rate payments to the counterparty (or CCP in the case of a centrally cleared swap) in exchange for payments on a floating benchmark interest rate. Payments received or made, including amortization of upfront payments/receipts, if any (which are amortized over the life of the swap contract), are recorded as realized gains or losses. During the term of the outstanding swap agreement, changes in the underlying value of the swap are recorded as unrealized gains or losses. For centrally cleared swaps, the daily change in valuation is recorded as a receivable or payable for variation margin and settled in cash with the CCP daily. The value of the swap is determined by changes in the relationship between two rates of interest. The Fund is exposed to credit loss in the event of non-performance by the swap counterparty. In the case of centrally cleared swaps, counterparty risk is minimal due to protections provided by the CCP. Risk may also arise from movements in interest rates.

N Credit Default Swaps—When the Fund is the buyer of a credit default swap contract, the Fund is entitled to receive the par (or other agreed-upon) value of a referenced debt obligation (or basket of debt obligations) from the counterparty (or CCP in the case of a centrally cleared swap) to the contract if a credit event by a third party, such as a U.S. or foreign corporate issuer or sovereign issuer, on the debt obligation occurs. In return, the Fund pays the counterparty a periodic stream of payments over the term of the contract provided that no credit event has occurred. If no credit event occurs, the Fund would have spent the stream of payments and received no proceeds from the contract. When the Fund is the seller of a credit default swap contract, it receives the stream of payments, but is obligated to pay to the buyer of the protection an amount up to the notional amount of the swap and in certain instances take delivery of securities of the reference entity upon the occurrence of a credit event, as defined under the terms of that particular swap agreement. Credit events are contract specific but may include bankruptcy, failure to pay, restructuring, obligation acceleration and repudiation/moratorium. If the Fund is a seller of protection and a credit event occurs, the maximum potential amount of future payments that the Fund could be required to make would be an amount equal to the notional amount of the agreement. This potential amount would be partially offset by any recovery value of the respective referenced obligation, or net amount received from the settlement of a buy protection credit default swap agreement entered into by the Fund for the same referenced obligation. As the seller, the Fund may create economic leverage to its portfolio because, in addition to its total net assets, the Fund is subject to investment exposure on the notional amount of the swap. The interest fee paid or received on the swap contract, which is based on a specified interest rate on a fixed notional amount, is accrued daily as a component of unrealized appreciation (depreciation) and is recorded as realized gain upon receipt or realized loss upon payment. The Fund also records an increase or decrease to unrealized appreciation (depreciation) in an amount equal to the daily valuation. For centrally cleared swaps, the daily change in valuation is recorded as a receivable or payable for variation margin and settled in cash with the CCP daily. All upfront payments and receipts, if any, are amortized over the life of the swap contract as realized gains or losses. Those upfront payments or receipts for non-centrally cleared swaps are recorded as other assets or other liabilities, respectively, net of amortization. For financial reporting purposes, unamortized upfront payments or receipts, if any, are netted with unrealized appreciation or depreciation on swap contracts to determine the market value of swaps as presented in Notes 8 and 11. These transactions involve certain risks, including the risk that the seller may be unable to fulfill the transaction. In the case of centrally cleared swaps, counterparty risk is minimal due to protections provided by the CCP.

O Swaptions—A purchased swaption contract grants the Fund, in return for payment of the purchase price, the right, but not the obligation, to enter into a new swap agreement or to shorten, extend, cancel or otherwise modify an existing swap agreement, at some designated future time on specified terms. When the Fund purchases a swaption, the premium paid to the writer is recorded as an investment and subsequently marked-to-market to reflect the current value of the swaption. A written swaption gives the Fund the obligation, if exercised by the purchaser, to enter into a swap contract according to the

Table of Contents

Eaton Vance

Emerging Markets Debt Opportunities Fund

January 31, 2024

Notes to Financial Statements (Unaudited) — continued

terms of the underlying agreement. When the Fund writes a swaption, the premium received by the Fund is recorded as a liability and subsequently marked-to-market to reflect the current value of the swaption. When a swaption is exercised, the cost of the swap is adjusted by the amount of the premium paid or received. When a swaption expires or an unexercised swaption is closed, a gain or loss is recognized in the amount of the premium paid or received, plus the cost to close. The Fund’s risk for purchased swaptions is limited to the premium paid. The writer of a swaption bears the risk of unfavorable changes in the preset terms of the underlying swap contract. Purchased swaptions traded over-the-counter involve risk that the issuer or counterparty will fail to perform its contractual obligations.

P Repurchase Agreements—A repurchase agreement is the purchase by the Fund 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 Fund 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 Fund 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 Fund 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 Fund 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.

Q Securities Sold Short—A short sale is a transaction in which the Fund 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 Fund must borrow the security to make delivery to the buyer with an obligation to replace such borrowed security at a later date. Until the security is replaced, the Fund 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 Fund 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 Fund 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.

R Interim Financial Statements—The interim financial statements relating to January 31, 2024 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 monthly 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. Distributions to shareholders are recorded on the ex-dividend date. Distributions are declared separately for each class of shares. Shareholders may reinvest income and capital gain distributions in additional shares of the same class 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. For the six months ended January 31, 2024, management estimates that a portion of distributions for the period will be a tax return of capital. The final determination of tax characteristics of the Fund’s distributions will occur at the end of the year and will be reported to the shareholders.

At July 31, 2023, the Fund, for federal income tax purposes, had deferred capital losses of $35,678,190 which would reduce its taxable income arising from future net realized gains on investment transactions, if any, to the extent permitted by the Internal Revenue Code, and thus would reduce the amount of distributions to shareholders, which would otherwise be necessary to relieve the Fund of any liability for federal income or excise tax. The deferred capital losses are treated as arising on the first day of the Fund’s next taxable year and retain the same short-term or long-term character as when originally deferred. Of the deferred capital losses at July 31, 2023, $35,678,190 are long-term.

Additionally, at July 31, 2023, the Fund had a late year ordinary loss of $51,362,465 which it has elected to defer to the following taxable year pursuant to income tax regulations. Late year ordinary losses represent certain specified losses realized in that portion of a taxable year after October 31 that are treated as ordinary for tax purposes plus ordinary losses attributable to that portion of a taxable year after December 31.

The cost and unrealized appreciation (depreciation) of investments, including open derivative contracts, of the Fund at January 31, 2024, as determined on a federal income tax basis, were as follows:

Aggregate cost	$1,737,937,493
Gross unrealized appreciation	$ 63,693,701
Gross unrealized depreciation	(93,423,585)
Net unrealized depreciation	$ (29,729,884)

3 Investment Adviser and Administration Fee and Other Transactions with Affiliates

The investment adviser and administration fee is earned by Eaton Vance Management (EVM), an indirect, wholly-owned subsidiary of Morgan Stanley, as compensation for investment advisory and administrative services rendered to the Fund. The fee is computed at an annual rate as a percentage of average daily net assets as follows and is payable monthly:

Average Daily Net Assets	Annual Fee Rate
Up to $500 million	0.650%
$500 million but less than $1.0 billion	0.625%
$1.0 billion but less than $2.5 billion	0.600%
$2.5 billion but less than $5.0 billion	0.580%
$5.0 billion and over	0.565%

For the six months ended January 31, 2024, the investment adviser and administration fee amounted to $4,920,167 or 0.62% (annualized) of the Fund’s average daily net assets. The Fund 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 and administration fee paid by the Fund is reduced by an amount equal to its pro rata share of the advisory and administration fees paid by the Fund due to its investment in the Liquidity Fund. For the six months ended January 31, 2024, the investment adviser and administration fee paid was reduced by $101,080 relating to the Fund’s investment in the Liquidity Fund.

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 January 31, 2024, EVM earned $4,656 from the Fund pursuant to such agreement, which is included in transfer and dividend disbursing agent fees on the Statement of Operations. The Fund was informed that Eaton Vance Distributors, Inc. (EVD), an affiliate of EVM and the Fund's principal underwriter, received $2,008 as its portion of the sales charge on sales of Class A shares for the six months ended January 31, 2024. EVD also received distribution and service fees from Class A shares (see Note 4).

Directors and officers of the Fund who are members of EVM’s organization receive remuneration for their services to the Fund out of the investment adviser and administration fee. Directors of the Fund who are not affiliated with EVM may elect to defer receipt of all or a percentage of their annual fees in accordance with the terms of the Directors Deferred Compensation Plan. Certain officers and Directors of the Fund are officers of EVM.

4 Distribution Plan

The Fund has in effect a distribution plan for Class A shares (Class A Plan) pursuant to Rule 12b-1 under the 1940 Act. Pursuant to the Class A Plan, the Fund pays EVD a distribution and service fee of 0.25% per annum of its average daily net assets attributable to Class A shares for distribution services and facilities provided to the Fund by EVD, as well as for personal services and/or the maintenance of shareholder accounts. Distribution and service fees paid or accrued to EVD for the six months ended January 31, 2024 amounted to $87,786 for Class A shares.

Distribution and service fees are subject to the limitations contained in the Financial Industry Regulatory Authority Rule 2341(d).

5 Contingent Deferred Sales Charges

Class A shares may be subject to a 0.75% contingent deferred sales charge (CDSC) if redeemed within 12 months of purchase (depending on the circumstances of purchase). Generally, the CDSC is based upon the lower of the net asset value at date of redemption or date of purchase. No charge is levied on shares acquired by reinvestment of dividends or capital gain distributions. For the six months ended January 31, 2024, the Fund was informed that EVD received no CDSCs paid by Class A shareholders.

At January 31, 2024, Eaton Vance Strategic Income Fund (formerly, Eaton Vance Short Duration Strategic Income Fund) and donor advised funds (established and maintained by a public charity) managed by EVM owned in the aggregate 10.9% of the value of the outstanding shares of the Fund.

8 Financial Instruments

The Fund may trade in financial instruments with off-balance sheet risk in the normal course of its investing activities. These financial instruments may include written options, forward foreign currency exchange contracts, non-deliverable bond forward contracts, futures contracts and swap 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 Fund 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 January 31, 2024 is included in the Portfolio of Investments. At January 31, 2024, the Fund had sufficient cash and/or securities to cover commitments under these contracts.

In the normal course of pursuing its investment objective, the Fund is subject to the following risks:

Credit Risk: The Fund enters into credit default swaps and swaptions to manage certain investment risks and/or to enhance total return or as a substitute for the purchase or sale of securities.

Foreign Exchange Risk: The Fund engages in forward foreign currency exchange contracts and currency options to enhance total return, to seek to hedge against fluctuations in currency exchange rates and/or as a substitute for the purchase or sale of securities or currencies.

Interest Rate Risk: The Fund utilizes various interest rate derivatives including non-deliverable bond forward contracts, interest rate futures contracts and interest rate swaps to enhance total return, to seek to hedge against fluctuations in interest rates, and/or to change the effective duration of its portfolio.

The Fund enters into over-the-counter (OTC) derivatives that may contain provisions whereby the counterparty may terminate the contract under certain conditions, including but not limited to a decline in the Fund’s net assets below a certain level over a certain period of time, which would trigger a payment by the Fund for those derivatives in a liability position. At January 31, 2024, the fair value of derivatives with credit-related contingent features in a net liability position was $7,189,304. The aggregate fair value of assets pledged as collateral by the Fund for such liability was $26,681,740 at January 31, 2024.

The OTC derivatives in which the Fund 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 Fund 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 Fund 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 Fund 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 Fund’s net assets decline by a stated percentage or the Fund fails to meet the terms of its ISDA Master Agreements, which would cause the counterparty to accelerate payment by the Fund 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 Fund and/or counterparty is held in segregated accounts by the Fund’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 Fund, a corresponding liability on the Statement of Assets and Liabilities. Securities pledged by the Fund as collateral, if any, are identified as such in the Portfolio of Investments. The carrying amount of the liability for cash collateral due to brokers at January 31, 2024 approximated its fair value. If measured at fair value, such liability would have been considered as Level 2 in the fair value hierarchy (see Note 11) at January 31, 2024.

The average notional cost of futures contracts and average notional amounts of other derivative contracts outstanding during the six months ended January 31, 2024, which are indicative of the volume of these derivative types, were approximately as follows:

Futures Contracts — Short	Forward Foreign Currency Exchange Contracts*	Non-Deliverable Bond Forward Contracts	Purchased Swaptions	Swap Contracts
$545,267,000	$1,096,314,000	$20,161,000	$115,500,000	$1,072,584,000

*	The average notional amount for forward foreign currency exchange contracts is based on the absolute value of notional amounts of currency purchased and currency sold.

The average principal amount of purchased and written currency options contracts outstanding during the six months ended January 31, 2024, which are indicative of the volume of these derivative types, were approximately $51,581,000 and $3,155,000, respectively.

9 Line of Credit

The Fund 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 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 Fund solely for temporary purposes related to redemptions and other short-term cash needs. Interest is charged to the Fund 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 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 Fund, it may be unable to borrow some or all of its requested amounts at any particular time. The Fund did not have any significant borrowings or allocated fees during the six months ended January 31, 2024.

10 Affiliated Investments

At January 31, 2024, the value of the Fund's investment in funds that may be deemed to be affiliated was $44,668,583, which represents 2.5% of the Fund's net assets. Transactions in such investments by the Fund for the six months ended January 31, 2024 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

11 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 January 31, 2024, the hierarchy of inputs used in valuing the Fund's investments and open derivative instruments, which are carried at fair value, were as follows:

Asset Description	Level 1	Level 2	Level 3	Total
Convertible Bonds	$ —	$ 17,383,223	$ —	$ 17,383,223

12 Risks and Uncertainties

Risks Associated with Foreign Investments

Foreign investments can be adversely affected by political, economic and market developments abroad, including the imposition of economic and other sanctions by the United States or another country. There may be less publicly available information about foreign issuers because they may not be subject to reporting practices, requirements or regulations comparable to those to which United States companies are subject. Foreign markets may be smaller, less liquid and more volatile than the major markets in the United States. Trading in foreign markets typically involves higher expense than trading in the United States. The Fund may have difficulties enforcing its legal or contractual rights in a foreign country. Securities that trade or are denominated in currencies other than the U.S. dollar may be adversely affected by fluctuations in currency exchange rates.

Emerging market securities often involve greater risks than developed market securities. Investment markets within emerging market countries are typically smaller, less liquid, less developed and more volatile than those in more developed markets like the United States, and may be focused in certain economic sectors. The information available about an emerging market issuer may be less reliable than for comparable issuers in more developed capital markets. Governmental actions can have a significant effect on the economic conditions in emerging market countries. It may be more difficult to make a claim or obtain a judgment in the courts of these countries than it is in the United States. The possibility of fraud, negligence, undue influence being exerted by an issuer or refusal to recognize ownership exists in some emerging markets. Disruptions due to work stoppages and trading improprieties in foreign securities markets have caused such markets to close. Emerging market securities are also subject to speculative trading, which contributes to their volatility.

Economic data as reported by sovereign entities may be delayed, inaccurate or fraudulent. In the event of a default by a sovereign entity, there are typically no assets to be seized or cash flows to be attached. Furthermore, the willingness or ability of a sovereign entity to restructure defaulted debt may be limited. Therefore, losses on sovereign defaults may far exceed the losses from the default of a similarly rated U.S. debt issuer.

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.
