(10) Restricted security. Total market value of restricted securities amounts to $1,291,941, which represents 0.1% of the net assets of the Fund as of March 31, 2026.
(11) Security converts to variable rate after the indicated fixed-rate coupon period.
(12) 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.

At March 31, 2026, the aggregate value of these securities is $9,744,084 or 0.7% of the Fund's net assets.
(13) Perpetual security with no stated maturity date but may be subject to calls by the issuer.
(14) When-issued security.
(15) Affiliated fund (see Note 8).
(16) 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”) 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.
(17) TBA (To Be Announced) securities are purchased or sold on a forward commitment basis with an approximate principal amount and maturity date. The actual principal amount, which is not expected to differ significantly from the commitment amount, and maturity date are determined upon settlement.
(18) May be deemed to be an affiliated investment company (see Note 8). The rate shown is the annualized seven-day yield as of March 31, 2026.
(19) Represents investment of cash collateral received in connection with securities lending.

* 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 March 31, 2026, the aggregate value of these securities is $1,220,015,832 or 28.8% of the Fund's net assets.
(2) Weighted average fixed-rate coupon that changes/updates monthly. Rate shown is the rate at March 31, 2026.
(3) Step coupon security. Interest rate represents the rate in effect at
March 31, 2026.
(4) Variable rate security. The stated interest rate represents the rate in effect at March 31, 2026.
(5) Inverse floating-rate security whose coupon varies inversely with changes in the interest rate index. The stated interest rate represents the coupon rate in effect at March 31, 2026.
(6) All or a portion of this security was on loan at March 31, 2026. The aggregate market value of securities on loan at March 31, 2026 was $24,064,306.
(7) Security converts to variable rate after the indicated fixed-rate coupon period.
(8) Perpetual security with no stated maturity date but may be subject to calls by the issuer.
(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 March 31, 2026, the aggregate value of these securities is $75,200,067 or 1.8% of the Fund's net assets.
(10) Affiliated fund (see Note 8).
(11) May be deemed to be an affiliated company (see Note 8).
(12) Restricted security. Total market value of restricted securities amounts to $8,495,485, which represents 0.2% of the net assets of the Fund as of March 31, 2026.
(13) 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”) 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.
(14) Build America Bond. Represents taxable municipal obligation issued pursuant to the American Recovery and Reinvestment Act of 2009 or other legislation providing for the issuance of taxable municipal debt on which the issuer receives federal support.
(15) Security (or a portion thereof) has been pledged to cover collateral requirements on open derivative contracts.
(16) TBA (To Be Announced) securities are purchased or sold on a forward commitment basis with an approximate principal amount and maturity date. The actual principal amount, which is not expected to differ significantly from the commitment amount, and maturity date are determined upon settlement.
(17) May be deemed to be an affiliated investment company (see Note 8). The rate shown is the annualized seven-day yield as of March 31, 2026.
(18) Represents investment of cash collateral received in connection with securities lending.

(1) 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 March 31, 2026, such maximum potential amount for all open credit default swaps in which the Fund is the seller was $4,000,000.
(2) 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.
(3) 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  Significant Accounting Policies
Calvert Balanced Fund (Balanced), Calvert Bond Fund (Bond) and Calvert Equity Fund (Equity) (each a Fund and collectively, the Funds) are diversified series of Calvert Social Investment Fund (the Trust). The Trust is a Massachusetts business trust registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company. The investment objective of Balanced is to seek to achieve a competitive total return through an actively managed portfolio of stocks, bonds, and money market instruments which offer income and capital growth opportunity. The investment objective of Bond is to seek to provide as high a level of current income as is consistent with preservation of capital through investment in bonds and other debt securities. The investment objective of Equity is to seek growth of capital through investment in stocks believed to offer opportunities for potential capital appreciation.
Each Fund offers four classes of shares. Class A shares are generally sold subject to a sales charge imposed at time of purchase. A contingent deferred sales charge of 1.00% for Balanced and Equity and 0.75% for Bond may apply to certain redemptions of Class A shares for accounts for which no sales charge was paid, if redeemed within 12 months of purchase. Class C shares are sold without a front-end sales charge, and with certain exceptions, are charged a contingent deferred sales charge of 1.00% on shares redeemed within 12 months of purchase. Class C shares are only available for purchase through a financial intermediary. Effective November 5, 2020, Class C shares automatically convert to Class A shares eight years after their purchase as described in the Funds’ prospectus. Class I and Class R6 shares are sold at net asset value, are not subject to a sales charge and are sold only to certain eligible investors. Each class represents a pro rata interest in each Fund, but votes separately on class-specific matters and is subject to different expenses.
Each Fund applies the accounting and reporting guidance in the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946, Financial Services – Investment Companies (ASC 946). Subsequent events, if any, through the date that the financial statements were issued have been evaluated in the preparation of the financial statements.
A  Investment Valuation— Net asset value per share is determined every business day as of the close of the regular session of the New York Stock Exchange (generally 4:00 p.m. Eastern time). The Funds use independent pricing services approved by the Board of Trustees (the Board) to value their investments wherever possible. Investments for which market quotations are not available or deemed not reliable are fair valued in good faith by the Board's valuation designee.
U.S. generally accepted accounting principles (U.S. GAAP) establishes a disclosure hierarchy that categorizes the inputs to valuation techniques used to value assets and liabilities at measurement date. These inputs are summarized in the three broad levels listed below:
Level 1 – quoted prices in active markets for identical securities
Level 2 – other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.)
Level 3 – significant unobservable inputs (including each Fund's own assumptions in determining the fair value of investments)
The inputs or methodologies used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.
Valuation techniques used to value each Fund's investments by major category are as follows:
Equity Securities. Equity securities (including warrants and rights) listed on a U.S. securities exchange generally are valued at the last sale or closing price as reported by an independent pricing service on the primary market or exchange on which they are traded and are categorized as Level 1 in the hierarchy. Equity securities listed on the NASDAQ National Market System are valued at the NASDAQ official closing price and are categorized as Level 1 in the hierarchy. 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 and are categorized as Level 2 in the hierarchy.
Debt Securities. Debt securities are generally valued based on 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. Accordingly, debt securities are generally categorized as Level 2 in the hierarchy. Short-term debt securities with a remaining maturity at time of purchase of more than sixty days are valued based on valuations provided by a third party pricing service. Such securities are generally categorized as Level 2 in the hierarchy. Short-term debt securities of sufficient credit quality purchased with remaining maturities 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, and are categorized as Level 2 in the hierarchy.
Senior Floating-Rate Loans. Interests in senior floating-rate loans for which reliable market quotations are readily available are valued generally at the average mean of bid and ask quotations obtained from a third party pricing service, and are categorized as Level 2 in the hierarchy.
Venture Capital Securities. Venture capital securities for which market quotations are not readily available are generally categorized as Level 3 in the hierarchy. Venture capital equity securities are generally valued using the most appropriate and applicable method to measure fair value in light of each company’s situation. Methods may include market, income, options-pricing or cost approaches with discounts as appropriate based on assumptions of liquidation or exit risk. Examples of the market approach are subsequent rounds of financing, comparable transactions, and revenue times an industry multiple. An example of the income approach is the discounted cash flow model. Examples of the cost approach are replacement cost, salvage value, or

Notes to Financial Statements (Unaudited) — continued

net asset value. The options-pricing method treats common stock and preferred stock as call options on the enterprise value with strike price based on the preferred stock liquidation preference. Venture capital limited partnership interests are valued at the fair value reported by the general partner of the partnership, adjusted as necessary to reflect subsequent capital calls and distributions and any other available information. In some cases, adjustments may be made to account for daily pricing of material public holdings within the partnership.
Other Securities.  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 and are categorized as Level 1 in the hierarchy. Exchange-traded funds are valued at the official closing price as reported by an independent pricing service on the primary market or exchange on which they are traded and are categorized as Level 1 in the hierarchy.
Derivatives. Futures contracts are valued at unrealized appreciation (depreciation) based on the settlement price established each day by the board of trade or exchange on which they are traded and are categorized as Level 1 in the hierarchy. 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 Funds' 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 and are categorized as Level 2 in the hierarchy. Swaps 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. Future cash flows on swaps are discounted to their present value using swap rates provided by electronic data services or by broker/dealers. Swaps are categorized as Level 2 in the hierarchy.
Fair Valuation. In connection with Rule 2a-5 of the 1940 Act, the Board has designated a 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 a 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.
The values assigned to fair value investments are based on available information and do not necessarily represent amounts that might ultimately be realized. Further, due to the inherent uncertainty of valuations of such investments, the fair values may differ significantly from the values that would have been used had an active market existed, and the differences could be material.
The following tables summarize the market value of each of the Funds' holdings as of March 31, 2026, based on the inputs used to value them:

(1) None of the unobservable inputs for Level 3 assets, individually or collectively, had a material impact on the Fund.
(2) The level classification by major category of investments is the same as the category presentation in the Schedule of Investments.
For Balanced and Equity, Level 3 investments at the beginning and/or end of the period in relation to net assets were not significant and accordingly, a reconciliation of Level 3 assets for the six months ended March 31, 2026 is not presented.
B  Investment Transactions and Income— Investment transactions for financial statement purposes are accounted for on trade date. Realized gains and losses are recorded on an identified cost basis and may include proceeds from litigation. Dividend income is recorded on the ex-dividend date for dividends received in cash and/or securities or, in the case of dividends on certain foreign securities, as soon as the Fund is informed of the ex-dividend date. Non-cash dividends are recorded at the fair value of the securities received. Withholding taxes on foreign dividends and interest, if any, have been provided for in accordance with the Funds' understanding of the applicable country’s tax rules and rates. Distributions received that represent a return of capital are recorded as a reduction of cost of investments. Distributions received that represent a capital gain are recorded as a realized gain. Interest income, which includes amortization of premium and accretion of discount on debt securities, is accrued as earned. The Funds may earn certain fees in connection with their investments in senior floating-rate loans. These fees are in addition to interest payments earned and may include amendment fees, consent fees and prepayment fees, which are recorded to income as earned. 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.
C  Share Class Accounting— Realized and unrealized gains and losses and net investment income and losses (except for Bond), other than class-specific expenses, are allocated daily to each class of shares based upon the relative net assets of each class to the total net assets of each Fund. For Bond, net investment income and losses, other than class-specific expenses, is allocated daily to each class of shares based upon the ratio of the value of each class’s paid shares to the total value of all paid shares. Expenses arising in connection with a specific class are charged directly to that class. Sub-accounting, recordkeeping and similar administrative fees payable to financial intermediaries, which are a component of transfer agency fees and expenses on the Statements of Operations, are not allocated to Class R6 shares.
D  Foreign Currency Transactions— The Funds’ accounting records are maintained in U.S. dollars. For valuation of assets and liabilities on each date of net asset value determination, foreign denominations are converted into U.S. dollars using the current exchange rate. Security transactions, income and expenses are translated at the prevailing rate of exchange on the date of the event. 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.
E  Senior Floating-Rate Loans— The Funds may invest in direct debt instruments, which are interests in amounts owed to lenders or lending syndicates by corporate, governmental, or other borrowers. The Funds’ investments in loans may be in the form of participations in loans or assignments of all or a portion of loans from third parties. A loan is often administered by a bank or other financial institution (the lender) that acts as agent for all holders. The agent administers the terms of the loan, as specified in the loan agreement. The Funds may invest in multiple series or tranches of a loan, which may have varying terms and carry different associated risks. When the Funds purchase assignments from lenders, they acquire direct rights against the borrower of
50

Social Investment Fund
March 31, 2026
Notes to Financial Statements (Unaudited) — continued

the loan. When investing in a loan participation, the Funds have the right to receive payments of principal, interest and any fees to which they are entitled only from the lender selling the loan agreement and only upon receipt of such payments by the lender from the borrower. The Funds generally have no right to enforce compliance by the borrower with the terms of the loan agreement. As a result, the Funds may be subject to the credit risk of both the borrower and the lender that is issuing the participation interest.
F  Unfunded Loan Commitments— The Funds may enter into certain loan agreements all or a portion of which may be unfunded. Each Fund is obligated to fund these commitments at the borrower's discretion. The commitments, if any, are disclosed in the accompanying Schedules of Investments.
G  Futures Contracts— The Funds may enter into futures contracts to buy or sell a financial instrument for a set price at a future date. Initial margin deposits of either cash or securities as required by the broker are made upon entering into the contract. While the contract is open, daily variation margin payments are made to or received from the broker reflecting the daily change in market value of the contract and are recorded for financial reporting purposes as unrealized gains or losses by the Funds. When a futures contract is closed, a realized gain or loss is recorded equal to the difference between the opening and closing value of the contract. The risks associated with entering into futures contracts may include the possible illiquidity of the secondary market which would limit the Funds' ability to close out a futures contract prior to the settlement date, an imperfect correlation between the value of the contracts and the underlying financial instruments, or that the counterparty will fail to perform its obligations under the contracts’ terms. Futures contracts are designed by boards of trade, which are designated “contracts markets” by the Commodities Futures Trading Commission. Futures contracts trade on the contracts markets in a manner that is similar to the way a stock trades on a stock exchange, and the boards of trade, through their clearing corporations, guarantee the futures contracts against default. As a result, there is minimal counterparty credit risk to the Funds.
H  Forward Foreign Currency Exchange Contracts— The Funds 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  Credit Default Swaps— Swap contracts are privately negotiated agreements between the Funds and a counterparty. Certain swap contracts may be centrally cleared (“centrally cleared swaps”), whereby all payments made or received by the Funds 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 swaps, the Funds are 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. When the Funds are the buyer of a credit default swap contract, the Funds are 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 Funds pay 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 Funds would have spent the stream of payments and received no proceeds from the contract. When the Funds are 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 Funds are a seller of protection and a credit event occurs, the maximum potential amount of future payments that the Funds 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 Funds for the same referenced obligation. As the seller, the Funds may create economic leverage to its portfolio because, in addition to its total net assets, the Funds are 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 Funds also record 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. 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.
J  Restricted Securities— The Funds may invest in securities that are subject to legal or contractual restrictions on resale. Generally, these securities may only be sold publicly upon registration under the Securities Act of 1933 or in transactions exempt from such registration. Information regarding restricted securities (excluding Rule 144A securities) is included at the end of each Fund's Schedule of Investments.
K  Distributions to Shareholders— Distributions to shareholders are recorded by the Funds on ex-dividend date. Distributions from net investment income are declared daily and paid monthly by Bond, quarterly by Balanced and annually by Equity. Distributions from net realized capital gains, if any, are paid at least annually. Distributions are declared separately for each class of shares. Distributions are determined in accordance with income tax regulations, which
51

Social Investment Fund
March 31, 2026
Notes to Financial Statements (Unaudited) — continued

may differ from U.S. GAAP; accordingly, periodic reclassifications are made within the Funds’ capital accounts to reflect income and gains available for distribution under income tax regulations.
L  Estimates— The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates.
M  Indemnifications— Under the Trust’s organizational document, its officers and Trustees may be indemnified against certain liabilities and expenses arising out of the performance of their duties to the Funds. Under Massachusetts law, if certain conditions prevail, shareholders of a Massachusetts business trust (such as the Trust) could be deemed to have personal liability for the obligations of the Trust. However, the Trust’s Declaration of Trust contains an express disclaimer of liability on the part of Fund shareholders and provides that the Trust shall assume, upon request by the shareholder, the defense on behalf of any Fund shareholders or former shareholders. Additionally, in the normal course of business, each Fund enters into agreements with service providers that may contain indemnification clauses. Each Fund’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against each Fund that have not yet occurred.
N  Federal and Other Taxes— No provision for federal income or excise tax is required since each Fund intends to continue to qualify as a regulated investment company under the Internal Revenue Code and to distribute substantially all of its taxable earnings.
Management has analyzed the Funds' tax positions taken for all open federal income tax years and has concluded that no provision for federal income tax is required in the Funds' financial statements. Each Fund's federal tax return is subject to examination by the Internal Revenue Service for a period of three years from the date of filing.
O  When-Issued Securities and Delayed Delivery Transactions— The Funds may purchase securities on a delayed delivery, when-issued or forward commitment basis, including TBA (To Be Announced) securities. Payment and delivery may take place after the customary settlement period for that security. At the time the transaction is negotiated, the price of the security that will be delivered is fixed. Securities purchased on a delayed delivery, when-issued or forward commitment basis are marked-to-market daily and begin earning interest on settlement date. Such security purchases are subject to the risk that when delivered they will be worth less than the agreed upon payment price. Losses may also arise if the counterparty does not perform under the contract. A forward purchase commitment may also be closed by entering into an offsetting commitment. If an offsetting commitment is entered into, the Funds will realize a gain or loss on investments based on the price established when the Funds entered into the commitment.
P  Segment Reporting— Each Fund operates as a single reportable segment, an investment company whose investment objective(s) is included in Note 1. The Funds’ President acts as each Fund's Chief Operating Decision Maker (CODM), who is responsible for assessing the performance of each Fund's single segment and deciding how to allocate the segment’s resources. To perform this function, the CODM reviews the information in the Funds’ financial statements.
Q  Interim Financial Statements— The interim financial statements relating to March 31, 2026 and for the six months then ended have not been audited by an independent registered public accounting firm, but in the opinion of the Funds’ management, reflect all adjustments, consisting only of normal recurring adjustments, necessary for the fair presentation of the financial statements.

Pursuant to an investment sub-advisory agreement, CRM has delegated the investment management of Equity to Atlanta Capital Management Company, LLC (Atlanta Capital), an affiliate of CRM and an indirect, wholly-owned subsidiary of Morgan Stanley. CRM pays Atlanta Capital a portion of its investment advisory fee for sub-advisory services provided to the Fund.
CRM has agreed to reimburse the Funds’ operating expenses to the extent that total annual operating expenses (relating to ordinary operating expenses only and excluding expenses such as brokerage commissions, acquired fund fees and expenses of unaffiliated funds, borrowing costs, taxes or litigation expenses) exceed, as a percentage of such class’s average daily net assets, the following amounts:
  Class A Class C Class I Class R6
Balanced 0.93% 1.68% 0.68% 0.64%
Bond 0.73% 1.53% 0.53% 0.46%

The administrative fee is earned by CRM as compensation for administrative services rendered to the Funds. The fee is computed at an annual rate of 0.12% of each Fund’s average daily net assets attributable to Class A, Class C, Class I and Class R6 and is payable monthly. For the six months ended March 31, 2026, CRM was paid administrative fees of $872,406, $2,500,915 and $2,851,326 for Balanced, Bond and Equity, respectively.
Each 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, each Fund pays Eaton Vance Distributors, Inc. (EVD), an affiliate of CRM and the Funds' principal underwriter, a distribution and service fee at a rate per annum of its average daily net assets attributable to Class A shares for distribution services and facilities provided to the Funds by EVD, as well as for personal services and/or the maintenance of shareholder accounts. Distribution and service fee rates for Class A shares are as follows:

Each Fund also has in effect a distribution plan for Class C shares (Class C Plan) pursuant to Rule 12b-1 under the 1940 Act. Pursuant to the Class C Plan, each Fund pays EVD amounts equal to 0.75% per annum of its average daily net assets attributable to Class C shares for providing ongoing distribution services and facilities to the Funds. In addition, pursuant to the Class C Plan, each Fund also makes payments of service fees to EVD, financial intermediaries and other persons in amounts equal to 0.25% per annum of its average daily net assets attributable to that class. Service fees paid or accrued are for personal services and/or the maintenance of shareholder accounts. Distribution and service fees for Balanced, Bond and Equity paid or accrued for the six months ended March 31, 2026 amounted to $1,124,956, $365,282 and $2,303,302, respectively, for Class A shares and $236,589, $46,705 and $410,316, respectively, for Class C shares.
The Funds were informed that EVD received $40,436, $12,045 and $29,497 for Balanced, Bond and Equity, respectively, as their portion of the sales charge on sales of Class A shares for the six months ended March 31, 2026. The Funds were informed that Morgan Stanley affiliated broker-dealers, which may be deemed to be affiliates of CRM and EVD, also received a portion of the sales charge on sales of Class A shares for the six months ended March 31, 2026 in the amount of $6,510, $1,540 and $4,609 for Balanced, Bond and Equity, respectively.
For the six months ended March 31, 2026, the Funds were also informed that EVD received the following amounts of contingent deferred sales charges paid by Class A and Class C shareholders:
  Balanced Bond Equity

Eligible Trustees may participate in a Deferred Compensation Plan (the Plan). Amounts deferred under the Plan are treated as though equal dollar amounts had been invested in shares of the Funds or other Calvert funds selected by the Trustees. The Funds purchase shares of the funds selected equal to the dollar amounts deferred under the Plan, resulting in an asset equal to the deferred compensation liability. Obligations of the Plan are paid solely from the Funds’ assets. Trustees’ fees are allocated to each of the Calvert funds served. Salaries and fees of officers and Trustees of the Funds who are employees of CRM or its affiliates are paid by CRM.

4  Distributions to Shareholders and Income Tax Information
At September 30, 2025, Bond Fund, for federal income tax purposes, had deferred capital losses of $245,437,301 which would reduce the Fund’s 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, can be carried forward for an unlimited period, and retain the same short-term or long-term character as when originally deferred. Of the deferred capital losses at September 30, 2025, $49,729,689 are short-term and $195,707,612 are long-term.
The cost and unrealized appreciation (depreciation) of investments, including open derivative contracts, of the Funds at March 31, 2026, as determined on a federal income tax basis, were as follows:
  Balanced Bond Equity
Aggregate cost $1,094,296,554 $4,681,893,611 $2,020,841,048
Gross unrealized appreciation $383,731,705 $21,858,281 $1,859,651,413
Gross unrealized depreciation (46,429,019) (98,758,895) (95,669,420)
Net unrealized appreciation (depreciation) $337,302,686 $(76,900,614) $1,763,981,993
5  Financial Instruments
The Funds may trade in financial instruments with off-balance sheet risk in the normal course of their investing activities. These financial instruments may include forward foreign currency exchange 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 a 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 March 31, 2026 is included in each Fund’s Schedule of Investments. At March 31, 2026, Balanced and Bond had sufficient cash and/or securities to cover commitments under these contracts. At March 31, 2026, there were no obligations outstanding under these financial instruments for Equity.
In the normal course of pursuing their investment objectives, Balanced and Bond are subject to the following risks:
Credit Risk: During the six months ended March 31, 2026, Bond Fund entered into credit default swap contracts 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: During the six months ended March 31, 2026, Balanced and Bond entered into forward foreign currency exchange contracts to seek to hedge against fluctuations in currency exchange rates.
Interest Rate Risk: During the six months ended March 31, 2026, Balanced and Bond entered into futures contracts to hedge interest rate risk and to manage duration.
Balanced and Bond enter into forward foreign currency exchange contracts and Bond 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 March 31, 2026, for Balanced and Bond, the fair value of derivatives with credit-related contingent features in a net liability position was $3,572 and $844,934, respectively. The aggregate fair value of assets pledged as collateral by Bond for such liability was $4,691,915 at March 31, 2026.
The over-the-counter (OTC) derivatives in which Balanced and Bond invest are subject to the risk that the counterparty to the contract fails to perform its obligations under the contract. To mitigate this risk, each Fund has entered into an International Swaps and Derivatives Association, Inc. Master Agreement (“ISDA Master Agreement”) with its derivative counterparty. The ISDA Master Agreement is a bilateral agreement between a Fund and the 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 ISDA Master Agreement. Under the 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. The ISDA Master Agreement allows the counterparty 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 Agreement, which would cause the counterparty to accelerate payment by the Fund of any net liability owed to it. The carrying amount of the liability for cash collateral due to brokers at March 31, 2026 approximated its fair value. If measured at fair value, such liability would have been considered Level 2 in the fair value hierarchy (see Note 1A) at March 31, 2026.
The collateral requirements for derivatives traded under the 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 the 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. Collateral pledged for the benefit of a 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 Statements of Assets and Liabilities. Securities pledged by a Fund as collateral, if any, are identified as such in the Schedule of Investments.

6  Securities Lending
To generate additional income, the Funds may lend their securities pursuant to a securities lending agency agreement with State Street Bank and Trust Company (SSBT), the securities lending agent. Security loans are subject to termination by the Funds at any time and, therefore, are not considered illiquid investments. The Funds require that the loan be continuously collateralized by either cash or securities in an amount at least equal to the market value of the securities on loan. The market value of securities loaned is determined daily and any additional required collateral is delivered to the Funds on the next business day. Cash collateral is generally invested in a money market fund registered under the 1940 Act that is managed by an affiliate of SSBT. Any gain or loss in the market price of the loaned securities that might occur and any interest earned or dividends declared during the term of the loan would accrue to the account of the Funds. Income earned on the investment of collateral, net of broker rebates and other expenses incurred by the securities lending agent, is split between the Funds and the securities lending agent based on agreed upon contractual terms. Non-cash collateral, if any, is held by the lending agent on behalf of a Fund and cannot be sold or re-pledged by the Fund; accordingly, such collateral is not reflected in the Statements of Assets and Liabilities.
The risks associated with lending portfolio securities include, but are not limited to, possible delays in receiving additional collateral or in the recovery of the loaned securities, possible loss of rights to the collateral should the borrower fail financially, as well as risk of loss in the value of the collateral or the value of the investments made with the collateral. The securities lending agent shall indemnify the Funds in the case of default of any securities borrower.
At March 31, 2026, the total value of securities on loan, including accrued interest, and the total value of collateral received were as follows:
  Balanced Bond
Securities on Loan $6,422,838 $24,164,063
Collateral Received:    
Cash 6,449,000 4,674,698
U.S. government and/or agencies securities  — 19,951,389
Total Collateral Received $6,449,000 $24,626,087
The following tables provide a breakdown of securities lending transactions accounted for as secured borrowings, the obligations by class of collateral pledged, and the remaining contractual maturity of those transactions as of March 31, 2026.

7  Line of Credit
The Funds participate with other portfolios and funds managed by EVM and its affiliates, including CRM, in a $650 million unsecured revolving line of credit agreement with a group of banks, which is in effect through October 20, 2026. Borrowings are made by the Funds solely for temporary purposes related to redemptions and other short-term cash needs. Interest is charged to each Fund based on its borrowings generally at an amount above either the Secured Overnight Financing Rate (SOFR) or Federal Funds rate. In addition, a fee computed at an annual rate of 0.15% on the daily unused portion of the line of credit is allocated among the participating portfolios and funds at the end of each quarter. In connection with the renewal of the agreement in October 2025, an arrangement fee 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 Funds, a Fund may be unable to borrow some or all of its requested amounts at any particular time.
Balanced, Bond and Equity had no borrowings pursuant to their line of credit during the six months ended March 31, 2026.
8  Affiliated Investments
During the six months ended March 31, 2026, Bond invested a portion of its assets in notes (the Notes) issued by Calvert Impact Capital, Inc. (CIC), pursuant to exemptive relief granted by the U.S. Securities and Exchange Commission (the SEC). There are certain potential points of affiliation between the Funds and CIC. CRM has licensed use of the Calvert name to CIC and provides other types of support. An officer of CRM's affiliate serves on the CIC Board.
Also, a Fund may invest in companies that are considered affiliated companies because the Fund has a direct or indirect ownership of, control of, or voting power of 5 percent or more of the outstanding voting shares of the company, or the company is under common ownership or control with the Fund. At March 31, 2026, the value of each Fund’s investment in the Notes and affiliated companies and in funds that may be deemed to be affiliated was $95,165,717, $490,636,557 and $130,031,347 for Balanced, Bond and Equity, respectively, which represents 7.0%, 11.5% and 3.4% of net assets for Balanced, Bond and Equity, respectively.

Notes to Financial Statements (Unaudited)

1  Significant Accounting Policies
Calvert Conservative Allocation Fund (Conservative), Calvert Moderate Allocation Fund (Moderate) and Calvert Growth Allocation Fund (Growth) (each a Fund and collectively, the Funds) are diversified series of Calvert Social Investment Fund (the Trust). The Trust is a Massachusetts business trust registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company. The investment objective of Conservative is to seek current income and capital appreciation, consistent with the preservation of capital. The investment objective of Moderate is to seek long-term capital appreciation and growth of income, with current income a secondary objective. The investment objective of Growth is to seek long-term capital appreciation. Each Fund is a "fund-of-funds" that invests primarily in a combination of other Calvert equity and income funds (the Underlying Funds). The financial statements of the Underlying Funds are available free of charge at www.calvert.com.
Each Fund offers four classes of shares. Class A shares are generally sold subject to a sales charge imposed at time of purchase. A contingent deferred sales charge of 1.00% may apply to certain redemptions of Class A shares for accounts for which no sales charge was paid, if redeemed within 12 months of purchase. Class C shares are sold without a front-end sales charge, and with certain exceptions, are charged a contingent deferred sales charge of 1.00% on shares redeemed within 12 months of purchase. Class C shares are only available for purchase through a financial intermediary. Effective November 5, 2020, Class C shares automatically convert to Class A shares eight years after their purchase as described in the Funds’ prospectus. Class I and Class R6 shares are sold at net asset value, are not subject to a sales charge and are sold only to certain eligible investors. Each class represents a pro rata interest in each Fund, but votes separately on class-specific matters and is subject to different expenses.
Each Fund applies the accounting and reporting guidance in the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946, Financial Services – Investment Companies (ASC 946). Subsequent events, if any, through the date that the financial statements were issued have been evaluated in the preparation of the financial statements.
A  Investment Valuation— Net asset value per share is determined every business day as of the close of the regular session of the New York Stock Exchange (generally 4:00 p.m. Eastern time). The Funds use independent pricing services approved by the Board of Trustees (the Board) to value their investments wherever possible. Investments for which market quotations are not available or deemed not reliable are fair valued in good faith by the Board's valuation designee.
U.S. generally accepted accounting principles (U.S. GAAP) establishes a disclosure hierarchy that categorizes the inputs to valuation techniques used to value assets and liabilities at measurement date. These inputs are summarized in the three broad levels listed below:
Level 1 – quoted prices in active markets for identical securities
Level 2 – other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.)
Level 3 – significant unobservable inputs (including each Fund's own assumptions in determining the fair value of investments)
The inputs or methodologies used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.
Valuation techniques used to value each Fund’s investments by major category are as follows:
Other Securities. Investments in the Underlying Funds and in money market funds are valued at the net asset value as of the close of each business day and are categorized as Level 1 in the hierarchy. Valuation methodologies and policies of the Underlying Funds are included in their financial statements, which are available upon request.
Derivatives. Futures contracts are valued at unrealized appreciation (depreciation) based on the settlement price established each day by the board of trade or exchange on which they are traded and are categorized as Level 1 in the hierarchy.
Fair Valuation. In connection with Rule 2a-5 of the 1940 Act, the Board has designated a 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 a 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.
The values assigned to fair value investments are based on available information and do not necessarily represent amounts that might ultimately be realized. Further, due to the inherent uncertainty of valuations of such investments, the fair values may differ significantly from the values that would have been used had an active market existed, and the differences could be material.

B  Investment Transactions and Income— Investment transactions for financial statement purposes are accounted for on trade date. Realized gains and losses are recorded on an identified cost basis and may include proceeds from litigation. Distributions from the Underlying Funds are recorded on the ex-dividend date. Distributions received that represent a return of capital are recorded as a reduction of cost of investments. Distributions received that represent a capital gain are recorded as a realized gain. Interest income is accrued as earned. Expenses included in the accompanying financial statements reflect the expenses of each Fund and do not include any expenses associated with the Underlying Funds.
C  Share Class Accounting— 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 upon the relative net assets of each class to the total net assets of each Fund. Expenses arising in connection with a specific class are charged directly to that class. Sub-accounting, recordkeeping and similar administrative fees payable to financial intermediaries, which are a component of transfer agency fees and expenses on the Statements of Operations, are not allocated to Class R6 shares.
D  Futures Contracts— The Funds may enter into futures contracts to buy or sell a financial instrument for a set price at a future date. Initial margin deposits of either cash or securities as required by the broker are made upon entering into the contract. While the contract is open, daily variation margin payments are made to or received from the broker reflecting the daily change in market value of the contract and are recorded for financial reporting purposes as unrealized gains or losses by the Funds. When a futures contract is closed, a realized gain or loss is recorded equal to the difference between the opening and closing value of the contract. The risks associated with entering into futures contracts may include the possible illiquidity of the secondary market which would limit the Funds' ability to close out a futures contract prior to the settlement date, an imperfect correlation between the value of the contracts and the underlying financial instruments, or that the counterparty will fail to perform its obligations under the contracts’ terms. Futures contracts are designed by boards of trade, which are designated “contracts markets” by the Commodities Futures Trading Commission. Futures contracts trade on the

Notes to Financial Statements (Unaudited) — continued

contracts markets in a manner that is similar to the way a stock trades on a stock exchange, and the boards of trade, through their clearing corporations, guarantee the futures contracts against default. As a result, there is minimal counterparty credit risk to the Funds.
E  Distributions to Shareholders— Distributions to shareholders are recorded by the Funds on ex-dividend date. Distributions from net investment income are declared and paid quarterly for Conservative and Moderate and annually for Growth. Distributions from net realized capital gains, if any, are paid at least annually. Distributions are declared separately for each class of shares. Distributions are determined in accordance with income tax regulations, which may differ from U.S. GAAP; accordingly, periodic reclassifications are made within the Funds’ capital accounts to reflect income and gains available for distribution under income tax regulations.
F  Estimates— The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates.
G  Indemnifications— Under the Trust’s organizational document, its officers and Trustees may be indemnified against certain liabilities and expenses arising out of the performance of their duties to the Funds. Under Massachusetts law, if certain conditions prevail, shareholders of a Massachusetts business trust (such as the Trust) could be deemed to have personal liability for the obligations of the Trust. However, the Trust’s Declaration of Trust contains an express disclaimer of liability on the part of Fund shareholders and provides that the Trust shall assume, upon request by the shareholder, the defense on behalf of any Fund shareholders or former shareholders. Additionally, in the normal course of business, each Fund enters into agreements with service providers that may contain indemnification clauses. Each Fund’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against each Fund that have not yet occurred.
H  Federal and Other Taxes— No provision for federal income or excise tax is required since each Fund intends to continue to qualify as a regulated investment company under the Internal Revenue Code and to distribute substantially all of its taxable earnings.
Management has analyzed the Fund's tax positions taken for all open federal income tax years and has concluded that no provision for federal income tax is required in the Fund's financial statements. Each Fund's federal tax return is subject to examination by the Internal Revenue Service for a period of three years from the date of filing.
I  Segment Reporting— Each Fund operates as a single reportable segment, an investment company whose investment objective(s) is included in Note 1. The Funds’ President acts as each Fund's Chief Operating Decision Maker (CODM), who is responsible for assessing the performance of each Fund's single segment and deciding how to allocate the segment’s resources. To perform this function, the CODM reviews the information in the Funds’ financial statements.
J  Interim Financial Statements— The interim financial statements relating to March 31, 2026 and for the six months then ended have not been audited by an independent registered public accounting firm, but in the opinion of the Funds' management, reflect all adjustments, consisting only of normal recurring adjustments, necessary for the fair presentation of the financial statements.
2  Related Party Transactions
Calvert Research and Management (CRM), an indirect, wholly-owned subsidiary of Morgan Stanley, provides investment advisory services to the Funds. CRM does not receive compensation from the Funds for performing investment advisory services. CRM does, however, receive a fee for investment advisory services provided to the Underlying Funds.
The Funds 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. Each Fund’s expenses are reduced by an amount equal to its pro rata share of the advisory and administration fees incurred by each Fund due to its investment in the Liquidity Fund. For the six months ended March 31, 2026, expenses reimbursed by CRM for Conservative, Moderate and Growth were $605, $594 and $989, respectively, relating to each Fund’s investment in the Liquidity Fund.
For Growth, CRM has agreed to reimburse the Fund’s operating expenses to the extent that total annual operating expenses (relating to ordinary operating expenses only and excluding expenses such as brokerage commissions, acquired fund fees and expenses, borrowing costs, taxes or litigation expenses) exceed 0.43%, 1.18%, 0.18% and 0.14% for Class A, Class C, Class I and Class R6, respectively, of such class’s average daily net assets. For Growth, the expense reimbursement agreement with CRM may be changed or terminated after February 1, 2027. For the six months ended March 31, 2026, CRM waived and/or reimbursed expenses of $16,763 for Growth. CRM serves as the administrator of the Funds, but receives no compensation.
Each 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, each Fund pays Eaton Vance Distributors, Inc. (EVD), an affiliate of CRM and the Funds' principal underwriter, 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 Funds by EVD, as well as for personal services and/or the maintenance of shareholder accounts. Each Fund also has in effect a distribution plan for Class C shares (Class C Plan) pursuant to Rule 12b-1 under the 1940 Act. Pursuant to the Class C Plan, each Fund pays EVD amounts equal to 0.75% per annum of its average daily

Notes to Financial Statements (Unaudited) — continued

net assets attributable to Class C shares for providing ongoing distribution services and facilities to the Funds. In addition, pursuant to the Class C Plan, each Fund also makes payments of service fees to EVD, financial intermediaries and other persons in amounts equal to 0.25% per annum of its average daily net assets attributable to that class. Service fees paid or accrued are for personal services and/or the maintenance of shareholder accounts. Distribution and service fees for Conservative, Moderate and Growth paid or accrued for the six months ended March 31, 2026 amounted to $211,355, $369,283 and $363,815, respectively, for Class A shares and $46,580, $78,737 and $81,225, respectively, for Class C shares.
The Funds were informed that EVD received $9,292, $16,070 and $28,411 for Conservative, Moderate and Growth, respectively, as their portion of the sales charge on sales of Class A shares for the six months ended March 31, 2026.
For the six months ended March 31, 2026, the Funds were also informed that EVD received the following amounts of contingent deferred sales charges paid by Class A and Class C shareholders:
  Conservative Moderate Growth
Class A $(1) $195 $1,340
Class C 252 222 303
    
(1) Amount is less than $100.
Eaton Vance Management (EVM), an affiliate of CRM, provides sub-transfer agency and related services to the Funds pursuant to a Sub-Transfer Agency Support Services Agreement. For the six months ended March 31, 2026, sub-transfer agency fees and expenses incurred to EVM amounted to $14,728, $27,008 and $30,446 for Conservative, Moderate and Growth, respectively, and are included in transfer agency fees and expenses on the Statements of Operations.
Each Trustee of the Funds who is not an employee of CRM or its affiliates receives an annual fee of $250,000, an annual Committee fee ranging from $8,500 to $16,500 depending on the Committee, and may receive a fee of $10,000 for special meetings. The Board chair receives an additional $75,000 ($55,000 prior to January 1, 2026) annual fee, Committee chairs receive an additional $20,000 annual fee and the special equities liaison receives an additional $2,500 annual fee. Eligible Trustees may participate in a Deferred Compensation Plan (the Plan). Amounts deferred under the Plan are treated as though equal dollar amounts had been invested in shares of the Funds or other Calvert funds selected by the Trustees. The Funds purchase shares of the funds selected equal to the dollar amounts deferred under the Plan, resulting in an asset equal to the deferred compensation liability. Obligations of the Plan are paid solely from the Funds' assets. Trustees’ fees are allocated to each of the Calvert funds served. Salaries and fees of officers and Trustees of the Funds who are employees of CRM or its affiliates are paid by CRM.
3  Investment Activity
During the six months ended March 31, 2026, the cost of purchases and proceeds from sales of investments, other than short-term securities, were as follows:
  Conservative Moderate Growth
Purchases $31,672,290 $66,622,039 $74,127,552
Sales 34,146,270 66,421,154 67,326,351
4  Distributions to Shareholders and Income Tax Information
At September 30, 2025, Conservative, for federal income tax purposes, had deferred capital losses of $2,686,904 which would reduce the Fund’s 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, can be carried forward for an unlimited period, and retain the same short-term or long-term character as when originally deferred. Of the deferred capital losses at September 30, 2025, $2,686,904 are short-term.

The effect of derivative instruments (not considered to be hedging instruments for accounting disclosure purposes) on the Statements of Operations and whose primary underlying risk exposure is interest rate risk for the six months ended March 31, 2026 was as follows:
Statements of Operations Caption Conservative Moderate
Net realized gain (loss):    
Futures contracts $214,621 $176,850
Total $214,621 $176,850
Change in unrealized appreciation (depreciation):    
Futures contracts $(331,652) $(272,783)
Total $(331,652) $(272,783)
The average notional cost of futures contracts outstanding during the six months ended March 31, 2026, which are indicative of the volume of these derivative types, were approximately as follows:
  Conservative Moderate
Futures contracts — long $5,904,000 $4,843,000
6  Line of Credit
The Funds participate with other portfolios and funds managed by EVM and its affiliates, including CRM, in a $650 million unsecured revolving line of credit agreement with a group of banks, which is in effect through October 20, 2026. Borrowings are made by the Funds solely for temporary purposes related to redemptions and other short-term cash needs. Interest is charged to each Fund based on its borrowings generally at an amount above either the Secured Overnight Financing Rate (SOFR) or Federal Funds rate. In addition, a fee computed at an annual rate of 0.15% on the daily unused portion of the line of credit is allocated among the participating portfolios and funds at the end of each quarter. In connection with the renewal of the agreement in October 2025, an arrangement fee 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 Funds, a Fund may be unable to borrow some or all of its requested amounts at any particular time.
At March 31, 2026, Growth had a balance outstanding pursuant to this line of credit of $230,000, at an annual interest rate of 4.64%. Based on the short-term nature of the borrowings under the line of credit and variable interest rate, the carrying value of the borrowings approximated its fair value at March 31, 2026. If measured at fair value, borrowings under the line of credit would have been considered as Level 2 in the fair value hierarchy (see Note 1A) at March 31, 2026.
Conservative and Growth did not have any significant borrowings or allocated fees during the six months ended March 31, 2026. Average borrowings and the weighted average annual interest rate (excluding fees) for Moderate for the six months ended March 31, 2026 were $1,661,484 and 4.66%.
7  Affiliated Investments
At March 31, 2026, the value of each Fund’s investment in affiliated funds, including funds that may be deemed to be affiliated, was $220,031,618, $371,564,728 and $348,682,359 for Conservative, Moderate and Growth, respectively, which represents 100.2%, 100.0% and 100.1% of net assets for Conservative, Moderate and Growth, respectively. Transactions in such investments by the Funds for the six months ended March 31, 2026 were as follows:

1  Significant Accounting Policies
Calvert Focused Value Fund (the Fund) is a diversified series of Calvert Social Investment Fund (the Trust). The Trust is a Massachusetts business trust registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company. The investment objective of the Fund is total return.
The Fund offers four classes of shares. Class A shares are generally sold subject to a sales charge imposed at time of purchase. A contingent deferred sales charge of 1.00% may apply to certain redemptions of Class A shares for accounts for which no sales charge was paid, if redeemed within 12 months of purchase. Class C shares are sold without a front-end sales charge, and with certain exceptions, are charged a contingent deferred sales charge of 1.00% on shares redeemed within 12 months of purchase. Class C shares are only available for purchase through a financial intermediary. Class C shares automatically convert to Class A shares eight years after their purchase as described in the Fund's prospectus. Class I and Class R6 shares are sold at net asset value, are not subject to a sales charge and are sold only to certain eligible investors. Each class represents a pro rata interest in the Fund, but votes separately on class-specific matters and is subject to different expenses.
The Fund applies the accounting and reporting guidance in the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946, Financial Services – Investment Companies (ASC 946). Subsequent events, if any, through the date that the financial statements were issued have been evaluated in the preparation of the financial statements.
A  Investment Valuation— Net asset value per share is determined every business day as of the close of the regular session of the New York Stock Exchange (generally 4:00 p.m. Eastern time). The Fund uses independent pricing services approved by the Board of Trustees (the Board) to value its investments wherever possible. Investments for which market quotations are not available or deemed not reliable are fair valued in good faith by the
Board’s valuation designee.
U.S. generally accepted accounting principles (U.S. GAAP) establishes a disclosure hierarchy that categorizes the inputs to valuation techniques used to value assets and liabilities at measurement date. These inputs are summarized in the three broad levels listed below:
Level 1 - quoted prices in active markets for identical securities
Level 2 - other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.)
Level 3 - significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments)
The inputs or methodologies used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.
Valuation techniques used to value the Fund’s investments by major category are as follows:
Equity Securities. Equity securities (including warrants and rights) listed on a U.S. securities exchange generally are valued at the last sale or closing price as reported by an independent pricing service on the primary market or exchange on which they are traded and are categorized as Level 1 in the hierarchy. Equity securities listed on the NASDAQ National Market System are valued at the NASDAQ official closing price and are categorized as Level 1 in the hierarchy. 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 and are categorized as Level 2 in the hierarchy. The daily valuation of exchange-traded foreign securities generally is determined as of the close of trading on the principal exchange on which such securities trade. Events occurring after the close of trading on foreign exchanges may result in adjustments to the valuation of foreign securities to more accurately reflect their fair value as of the close of regular trading on the New York Stock Exchange. When valuing foreign equity securities that meet certain criteria, the Fund’s Board has approved the use of a fair value service that values such securities to reflect market trading that occurs after the close of the applicable foreign markets of comparable securities or other instruments that have a strong correlation to the fair-valued securities. Such securities are categorized as Level 2 in the hierarchy.
Other Securities.  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 and are categorized as Level 1 in the hierarchy.
Fair Valuation. In connection with Rule 2a-5 of the 1940 Act, the Board has 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.
The values assigned to fair value investments are based on available information and do not necessarily represent amounts that might ultimately be realized. Further, due to the inherent uncertainty of valuations of such investments, the fair values may differ significantly from the values that would have been used had an active market existed, and the differences could be material.

Notes to Financial Statements (Unaudited) — continued

The following table summarizes the market value of the Fund's holdings as of March 31, 2026, based on the inputs used to value them:
Asset Description Level 1 Level 2 Level 3 Total
Common Stocks $12,130,344(1) $ — $ — $12,130,344
Short-Term Investments 117,782  —  — 117,782
Total Investments $12,248,126 $ — $ — $12,248,126
    
(1) The level classification by major category of investments is the same as the category presentation in the Schedule of Investments.
B  Investment Transactions and Income— Investment transactions for financial statement purposes are accounted for on trade date. Realized gains and losses are recorded on an identified cost basis and may include proceeds from litigation. Dividend income is recorded on the ex-dividend date for dividends received in cash and/or securities or, in the case of dividends on certain foreign securities, as soon as the Fund is informed of the ex-dividend date. Non-cash dividends are recorded at the fair value of the securities received. Withholding taxes on foreign dividends, if any, have been provided for in accordance with the Fund’s understanding of the applicable country’s tax rules and rates. Distributions received that represent a return of capital are recorded as a reduction of cost of investments. Distributions received that represent a capital gain are recorded as a realized gain.
C  Share Class Accounting— 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 upon the relative net assets of each class to the total net assets of the Fund. Expenses arising in connection with a specific class are charged directly to that class. Sub-accounting, recordkeeping and similar administrative fees payable to financial intermediaries, which are a component of transfer agency fees and expenses on the Statement of Operations, are not allocated to Class R6 shares.
D  Foreign Currency Transactions— The Fund’s accounting records are maintained in U.S. dollars. For valuation of assets and liabilities on each date of net asset value determination, foreign denominations are converted into U.S. dollars using the current exchange rate. Security transactions, income and expenses are translated at the prevailing rate of exchange on the date of the event. 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.
E  Distributions to Shareholders— Distributions to shareholders are recorded by the Fund on ex-dividend date. Distributions from net investment income and distributions from net realized capital gains, if any, are paid at least annually. Distributions are declared separately for each class of shares. Distributions are determined in accordance with income tax regulations, which may differ from U.S. GAAP; accordingly, periodic reclassifications are made within the Fund's capital accounts to reflect income and gains available for distribution under income tax regulations.
F  Estimates— The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates.
G  Indemnifications— Under the Trust’s organizational document, its officers and Trustees may be indemnified against certain liabilities and expenses arising out of the performance of their duties to the Fund. Under Massachusetts law, if certain conditions prevail, shareholders of a Massachusetts business trust (such as the Trust) could be deemed to have personal liability for the obligations of the Trust. However, the Trust’s Declaration of Trust contains an express disclaimer of liability on the part of Fund shareholders and provides that the Trust shall assume, upon request by the shareholder, the defense on behalf of any Fund shareholders or former shareholders. 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.
H  Federal and Other Taxes— No provision for federal income or excise tax is required since the Fund intends to qualify as a regulated investment company under the Internal Revenue Code and to distribute substantially all of its taxable earnings. Management has analyzed the Fund's tax positions taken for all open federal income tax years and has concluded that no provision for federal income tax is required in the Fund's financial statements. A Fund's federal tax return is subject to examination by the Internal Revenue Service for a period of three years from the date of filing.
I  Segment Reporting— The Fund operates as a single reportable segment, an investment company whose investment objective(s) is included in Note 1. The Fund’s President acts as the Fund's Chief Operating Decision Maker (CODM), who is responsible for assessing the performance of the Fund's single segment and deciding how to allocate the segment’s resources. To perform this function, the CODM reviews the information in the Fund’s financial statements.
J  Interim Financial Statements— The interim financial statements relating to March 31, 2026 and for the six months then ended have not been audited by an independent registered public accounting firm, but in the opinion of the Fund's management, reflect all adjustments, consisting only of normal recurring adjustments, necessary for the fair presentation of the financial statements.

4  Distributions to Shareholders and Income Tax Information
The cost and unrealized appreciation (depreciation) of investments of the Fund at March 31, 2026, as determined on a federal income tax basis, were as follows:
Aggregate cost $10,252,217
Gross unrealized appreciation $2,342,784
Gross unrealized depreciation (346,875)
Net unrealized appreciation $1,995,909
5  Securities Lending
To generate additional income, the Fund may lend its securities pursuant to a securities lending agency agreement with State Street Bank and Trust Company (SSBT), the securities lending agent. Security loans are subject to termination by the Fund at any time and, therefore, are not considered illiquid investments. The Fund requires that the loan be continuously collateralized by either cash or securities in an amount at least equal to the market value of the securities on loan. The market value of securities loaned is determined daily and any additional required collateral is delivered to the Fund on the next business day. Cash collateral is generally invested in a money market fund registered under the 1940 Act that is managed by an affiliate of SSBT. Any gain or loss in the market price of the loaned securities that might occur and any interest earned or dividends declared during the term of the loan would accrue to the account of the Fund. Income earned on the investment of collateral, net of broker rebates and other expenses incurred by the securities lending agent, is split between the Fund and the securities lending agent based on agreed upon contractual terms. Non-cash collateral, if any, is held by the lending agent on behalf of the Fund and cannot be sold or re-pledged by the Fund; accordingly, such collateral is not reflected in the Statement of Assets and Liabilities.
The risks associated with lending portfolio securities include, but are not limited to, possible delays in receiving additional collateral or in the recovery of the loaned securities, possible loss of rights to the collateral should the borrower fail financially, as well as risk of loss in the value of the collateral or the value of the investments made with the collateral. The securities lending agent shall indemnify the Fund in the case of default of any securities borrower.
The Fund did not have any securities on loan at March 31, 2026.
6  Line of Credit
The Fund participates with other portfolios and funds managed by EVM and its affiliates, including CRM, in a $650 million unsecured revolving line of credit agreement with a group of banks, which is in effect through October 20, 2026. Borrowings are made by the Fund solely for temporary purposes related to redemptions and other short-term cash needs. Interest is charged to the Fund based on its borrowings generally at an amount above either the Secured Overnight Financing Rate (SOFR) or Federal Funds rate. In addition, a fee computed at an annual rate of 0.15% on the daily unused portion of the line of credit is allocated among the participating portfolios and funds at the end of each quarter. In connection with the renewal of the agreement in October 2025, an arrangement fee 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 had no borrowings outstanding pursuant to its line of credit at March 31, 2026. The Fund did not have any significant borrowings or allocated fees during the six months ended March 31, 2026.
7  Affiliated Investments
