The Gabelli ABC Fund

Notes to Financial Statements

1. Organization. The Gabelli ABC Fund (the Fund), the sole series of the Gabelli Investor Funds, Inc. (the Corporation), was incorporated on October 30, 1992 in Maryland. The Fund is a non-diversified open-end management investment company registered under the Investment Company Act of 1940, as amended (the 1940 Act). The Fund's primary objective is to achieve total returns that are attractive to investors in various market conditions without excessive risk of capital loss. The Fund commenced investment operations on May 14, 1993.

Gabelli Funds, LLC (the Adviser), with its principal offices located at One Corporate Center, Rye, New York 10580-1422, serves as investment adviser to the Fund. The Adviser makes investment decisions for the Fund and continuously reviews and administers the Fund's investment program and manages the operations of the Fund under the general supervision of the Fund's Board of Directors (the Board).

Effective September 29, 2025, Class AAA shares of the Fund were renamed Class I shares.

2. Significant Accounting Policies. As an investment company, the Fund follows the investment company accounting and reporting guidance, which is part of U.S. generally accepted accounting principles (GAAP) that may require the use of management estimates and assumptions in the preparation of its financial statements. Actual results could differ from those estimates. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements.

Security Valuation. The Board has designated the Adviser as the valuation designee (Valuation Designee) under Rule 2a-5. Portfolio securities listed or traded on a nationally recognized securities exchange or traded in the U.S. over-the-counter market for which market quotations are readily available are valued at the last quoted sale price or a market's official closing price as of the close of business on the day the securities are being valued. If there were no sales that day, the security is valued at the average of the closing bid and asked prices or, if there were no asked prices quoted on that day, then the security is valued at the closing bid price on that day. If no bid or asked prices are quoted on such day, the security is valued at the most recently available price or, if the Valuation Designee so determines, by such other method as the Valuation Designee shall determine in good faith to reflect its fair market value. For short positions, if no bid prices are quoted on that day, then the security is valued at the closing ask price on the principal market for the security on that day. Portfolio securities traded on more than one national securities exchange or market are valued according to the broadest and most representative market, as determined by the Adviser.

Portfolio securities primarily traded on a foreign market are generally valued at the preceding closing values of such securities on the relevant market, but may be fair valued pursuant to procedures established by the Valuation Designee if market conditions change significantly after the close of the foreign market, but prior to the close of business on the day the securities are being valued. Debt obligations for which market quotations are readily available are valued at the average of the latest bid and asked prices. If there were no asked prices quoted on such day, the security is valued using the closing bid price, unless the Valuation Designee determines such amount does not reflect the security's fair value, in which case these securities will be fair valued as determined by the Valuation Designee. Certain securities are valued principally using dealer quotations. Futures contracts are valued at the closing settlement price of the exchange or board of trade on which the applicable contract is traded. OTC futures and options on futures for which market quotations are readily available will be valued by quotations received from a pricing service or, if no quotations are available from a pricing service, by quotations obtained from one of more dealers in the instrument in question by the Adviser.

11

The Gabelli ABC Fund

Notes to Financial Statements (Continued)

Securities and assets for which market quotations are not readily available are fair valued as determined by the Valuation Designee. Fair valuation methodologies and procedures may include, but are not limited to: analysis and review of available financial and non-financial information about the company; comparisons with the valuation and changes in valuation of similar securities, including a comparison of foreign securities with the equivalent U.S. dollar value American Depositary Receipt securities at the close of the U.S. exchange; and evaluation of any other information that could be indicative of the value of the security.

The inputs and valuation techniques used to measure fair value of the Fund's investments are summarized into three levels as described in the hierarchy below:

Level 1 - unadjusted 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.); and
Level 3 - significant unobservable inputs (including the Board's determinations as to the fair value of investments).

A financial instrument's level within the fair value hierarchy is based on the lowest level of any input both individually and in the aggregate that is significant to the fair value measurement. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

The summary of the Fund's investments in securities and other financial instruments by inputs used to value the Fund's investments as of December 31, 2025 are as follows:

At December 31, 2025, the total value of Level 3 investments for the Fund was less than 1% of total net assets.

General. The Fund uses recognized industry pricing services - approved by the Board and unaffiliated with the Adviser - to value most of its securities, and uses broker quotes provided by market makers of securities not valued by these and other recognized pricing sources. Several different pricing feeds are received to value domestic equity securities, international equity securities, preferred equity securities, and fixed income securities. The data within these feeds are ultimately sourced from major stock exchanges and trading systems where these securities trade. The prices supplied by external sources are checked by obtaining quotations or actual transaction prices from market participants. If a price obtained from the pricing source is deemed unreliable, prices will be sought from another pricing service or from a broker/dealer that trades that security or similar securities.

Fair Valuation. Fair valued securities may be common or preferred equities, warrants, options, rights, or fixed income obligations. Where appropriate, Level 3 securities are those for which market quotations are not available, such as securities not traded for several days, or for which current bids are not available, or which are restricted as to transfer. When fair valuing a security, factors to consider include recent prices of comparable securities that are publicly traded, reliable prices of securities not publicly traded, the use of valuation models, current analyst reports, valuing the income or cash flow of the issuer, or cost if the preceding factors do not apply. A significant change in the unobservable inputs could result in a lower or higher value in Level 3 securities. The circumstances of Level 3 securities are frequently monitored to determine if fair valuation measures continue to apply.

The Adviser reports quarterly to the Board the results of the application of fair valuation policies and procedures. These may include backtesting the prices realized in subsequent trades of these fair valued securities to fair values previously recognized.

Derivative Financial Instruments. The Fund may engage in various portfolio investment strategies by investing in derivative financial instruments for the purposes of increasing the income of the Fund, hedging against changes in the value of its portfolio securities and in the value of securities it intends to purchase, or hedging

The Gabelli ABC Fund

Notes to Financial Statements (Continued)

against a specific transaction with respect to either the currency in which the transaction is denominated or another currency. Investing in certain derivative financial instruments, including participation in currencies options, futures, or swap markets, entails certain execution, liquidity, hedging, tax, securities, interest, credit, or currency market risks. Losses may arise if the Adviser's prediction of movements in the direction of the securities, foreign currency, and interest rate markets is inaccurate. Losses may also arise if the counterparty does not perform its duties under a contract, or, in the event of default, the Fund may be delayed in or prevented from obtaining payments or other contractual remedies owed to it under derivative contracts. The creditworthiness of the counterparties is closely monitored in order to minimize these risks. Participation in derivative transactions involves investment risks, transaction costs, and potential losses to which the Fund would not be subject absent the use of these strategies. The consequences of these risks, transaction costs, and losses may have a negative impact on the Fund's ability to pay distributions.

Collateral requirements differ by type of derivative. Collateral requirements are set by the broker or exchange clearing house for exchange traded derivatives, while collateral terms are contract specific for derivatives traded over-the-counter. Securities pledged to cover obligations of the Fund under derivative contracts are noted in the Schedule of Investments. Cash collateral, if any, pledged for the same purpose will be reported separately in the Statement of Assets and Liabilities.

The Fund's policy with respect to offsetting is that, absent an event of default by the counterparty or a termination of the agreement, the master agreement does not result in an offset of reported amounts of financial assets and financial liabilities in the Statement of Assets and Liabilities across transactions between the Fund and the applicable counterparty. Therefore the Fund reflects derivative assets and liabilities any related collateral gross on the statement of assets and liabilities. The enforceability of the right to offset may vary by jurisdiction.

The Fund's derivative contracts held at December 31, 2025, if any, are not accounted for as hedging instruments under GAAP and are disclosed in the Schedule of Investments together with the related counterparty.

Swap Agreements. The Fund may enter into equity contract for difference swap transactions for the purpose of increasing the income of the Fund. The use of swaps is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio security transactions. In an equity contract for difference swap, a set of future cash flows is exchanged between two counterparties. One of these cash flow streams will typically be based on a reference interest rate combined with the performance of a notional value of shares of a stock. The other will be based on the performance of the shares of a stock. Depending on the general state of short term interest rates and the returns on the Fund's portfolio securities at the time an equity contract for difference swap transaction reaches its scheduled termination date, there is a risk that the Fund will not be able to obtain a replacement transaction or that the terms of the replacement will not be as favorable as on the expiring transaction.

Unrealized gains related to swaps are reported as an asset and unrealized losses are reported as a liability in the Statement of Assets and Liabilities. The change in value of swaps, including the accrual of periodic amounts of interest to be received or paid on swaps, is reported as unrealized gain or loss in the Statement of Operations. A realized gain or loss is recorded upon receipt or payment of a periodic payment or termination of swap agreements. During the year ended December 31, 2025, the Fund held no investments in equity contract for difference swap agreements.

Notes to Financial Statements (Continued)

Forward Foreign Exchange Contracts. The Fund may engage in forward foreign exchange contracts for the purpose of hedging a specific transaction with respect to either the currency in which the transaction is denominated or another currency as deemed appropriate by the Adviser. Forward foreign exchange contracts are valued at the forward rate and are marked-to-market daily. The change in market value is included in unrealized appreciation/depreciation on forward foreign exchange contracts. When the contract is closed, the Fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed.

The use of forward foreign exchange contracts does not eliminate fluctuations in the underlying prices of the Fund's portfolio securities, but it does establish a rate of exchange that can be achieved in the future. Although forward foreign exchange contracts limit the risk of loss due to a decline in the value of the hedged currency, they also limit any potential gain that might result should the value of the currency increase. Forward foreign exchange contracts at December 31, 2025 are reflected within the Schedule of Investments. The Fund's volume of activity in forward foreign exchange contracts during the year ended December 31, 2025 had an average monthly notional amount of approximately $11,675,018.

At December 31, 2025, the value of forward foreign exchange contracts can be found in the Statement of Assets and Liabilities under Assets, Unrealized appreciation on forward foreign exchange contracts. For the year ended December 31, 2025, the effect of forward foreign exchange contracts can be found in the Statement of Operations under Net Realized and Unrealized Gain/(Loss) on Investments in Securities, Securities Sold Short, Forward Foreign Exchange Contracts, and Foreign Currency, within Net realized loss on forward foreign exchange contracts and Net change in unrealized appreciation/depreciation on forward foreign exchange contracts.

Securities Sold Short. The Fund entered into short sale transactions. Short selling involves selling securities that may or may not be owned and, at times, borrowing the same securities for delivery to the purchaser, with an obligation to replace such borrowed securities at a later date. The proceeds received from short sales are recorded as liabilities and the Fund records an unrealized gain or loss to the extent of the difference between the proceeds received and the value of an open short position on the day of determination. The Fund records a realized gain or loss when the short position is closed out. By entering into a short sale, the Fund bears the market risk of an unfavorable change in the price of the security sold short. Dividends on short sales are recorded as an expense by the Fund on the ex-dividend date and interest expense is recorded on the accrual basis. The broker retains collateral for the value of the open positions, which is adjusted periodically as the value of the position fluctuates. Securities sold short and details of collateral at December 31, 2025 are reflected within the Schedule of Investments. For the year ended December 31, 2025, the Fund incurred $1,163 in service fees related to its investment positions sold short and held by the broker. These amounts are included in the Statement of Operations under Expenses, Service fees for securities sold short.

Foreign Currency Translations. The books and records of the Fund are maintained in U.S. dollars. Foreign currencies, investments, and other assets and liabilities are translated into U.S. dollars at current exchange rates. Purchases and sales of investment securities, income, and expenses are translated at the exchange rate prevailing on the respective dates of such transactions. Unrealized gains and losses that result from changes in foreign exchange rates and/or changes in market prices of securities have been included in unrealized appreciation/depreciation on investments and foreign currency translations. Net realized foreign currency gains and losses resulting from changes in exchange rates include foreign currency gains and losses between trade date and settlement date on investment securities transactions, foreign currency transactions, and the difference between the amounts of interest and dividends recorded on the books of the Fund and the amounts actually

received. The portion of foreign currency gains and losses related to fluctuation in exchange rates between the initial purchase trade date and subsequent sale trade date is included in realized gain/(loss) on investments.

Foreign Securities. The Fund may directly purchase securities of foreign issuers. Investing in securities of foreign issuers involves special risks not typically associated with investing in securities of U.S. issuers. The risks include possible revaluation of currencies, the inability to repatriate funds, less complete financial information about companies, and possible future adverse political and economic developments. Moreover, securities of many foreign issuers and their markets may be less liquid and their prices more volatile than securities of comparable U.S. issuers.

Foreign Taxes. The Fund may be subject to foreign taxes on income, gains on investments, or currency repatriation, a portion of which may be recoverable. The Fund will accrue such taxes and recoveries as applicable, based upon its current interpretation of tax rules and regulations that exist in the markets in which it invests.

Restricted Securities. The Fund may invest up to 15% of its net assets in securities for which the markets are restricted. Restricted securities include securities whose disposition is subject to substantial legal or contractual restrictions. The sale of restricted securities often requires more time and results in higher brokerage charges or dealer discounts and other selling expenses than the sale of securities eligible for trading on national securities exchanges or in the over-the-counter markets. Restricted securities may sell at a price lower than similar securities that are not subject to restrictions on resale. Securities freely saleable among qualified institutional investors under special rules adopted by the SEC may be treated as liquid if they satisfy liquidity standards established by the Board. The continued liquidity of such securities is not as well assured as that of publicly traded securities, and accordingly the Board will monitor their liquidity. At December 31, 2025, the Fund did not hold any restricted securities.

Securities Transactions and Investment Income. Securities transactions are accounted for on the trade date with realized gain/(loss) on investments determined by using the identified cost method. Interest income (including amortization of premium and accretion of discount) is recorded on an accrual basis. Premiums and discounts on debt securities are amortized using the effective yield to maturity method or amortized to earliest call date, if applicable. Dividend income is recorded on the ex-dividend date, except for certain dividends from foreign securities that are recorded as soon after the ex-dividend date as the Fund becomes aware of such dividends. The Fund owns real-estate investment trusts (REITs), and the distributions received from REITs may be classified as dividends, capital gains, or return of capital.

Determination of Net Asset Value and Calculation of Expenses. Certain administrative expenses are common to, and allocated among, various affiliated funds. Such allocations are made on the basis of the Fund's average net assets or other criteria directly affecting the expenses as determined by the Adviser pursuant to procedures established by the Board.

In calculating the NAV per share of each class, investment income, realized and unrealized gains and losses, redemption fees, and expenses other than class specific expenses are allocated daily to each class of shares based upon the proportion of net assets of each class at the beginning of each day. Distribution expenses are borne solely by the class incurring the expense.

Distributions to Shareholders. Distributions to shareholders are recorded on the ex-dividend date. Distributions to shareholders are based on income and capital gains as determined in accordance with federal income tax regulations, which may differ from income and capital gains as determined under GAAP. These differences are

17

The Gabelli ABC Fund

Notes to Financial Statements (Continued)

primarily due to differing treatments of income and gains on various investment securities and foreign currency transactions held by the Fund, timing differences, and differing characterizations of distributions made by the Fund. Distributions from net investment income for federal income tax purposes include net realized gains on foreign currency transactions. These book/tax differences are either temporary or permanent in nature. To the extent these differences are permanent, adjustments are made to the appropriate capital accounts in the period when the differences arise. Permanent differences were primarily due to utilization of tax equalization. These reclassifications have no impact on the NAV of the Fund. For the year ended December 31, 2025, reclassifications were made to increase paid-in capital by $693,535, with an offsetting adjustment to total distributable earnings.

The tax character of distributions paid during the years ended December 31, 2025 and 2024 was as follows:

Year ended

2025

Ordinary income $ 12,711,109 $ 16,443,940
Net long term capital gains 6,422,807 4,517,861
Total distributions paid $ 19,133,916 $ 20,961,801

Provision for Income Taxes. The Fund intends to continue to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code of 1986, as amended (the Code). It is the policy of the Fund to comply with the requirements of the Code applicable to regulated investment companies and to distribute substantially all of its net investment company taxable income and net capital gains. Therefore, no provision for federal income taxes is required.

At December 31, 2025, the components of accumulated earnings/losses on a tax basis were as follows:

Net unrealized appreciation on investments, foreign currency translations, and forward foreign exchange contracts $ 38,507,777
Other temporary differences* (579,060 )
Total $ 37,928,717
* Other temporary differences are due to short positions.

The Fund is permitted to carry capital losses forward for an unlimited period. Capital losses that are carried forward will retain their character as either short term or long term capital losses.

At December 31, 2025, the temporary difference between book basis and tax basis net unrealized appreciation on investments was primarily due to deferral of losses from wash sales for tax purposes and tax treatment of constructive sales and basis adjustments on investments in partnerships.

The Fund is required to evaluate tax positions taken or expected to be taken in the course of preparing the Fund's tax returns to determine whether the tax positions are "more-likely-than-not" of being sustained by the applicable tax authority. Income tax and related interest and penalties would be recognized by the Fund as tax expense in the Statement of Operations if the tax positions were deemed not to meet the more-likely-than-not threshold. During the year ended December 31, 2025, the Fund did not incur any income tax, interest, or penalties. As of December 31, 2025, the Adviser has reviewed all open tax years and concluded that there was no impact to the Fund's net assets or results of operations. The Fund's federal and state tax returns for the prior three fiscal years remain open, subject to examination. On an ongoing basis, the Adviser will monitor the Fund's tax positions to determine if adjustments to this conclusion are necessary.

Recent Accounting Pronouncement. During the reporting period, the Fund adopted Accounting Standards Update 2023-09, Income Taxes (Topic 740)-Improvements to Income Tax Disclosures ("ASU 2023-09"). The amendment enhances income tax disclosures by requiring greater disclosure of income taxes paid by jurisdiction. During the reporting period, the Fund paid less than 1% in foreign or U.S. federal, state or local income taxes.

3. Investment Advisory Agreement and Other Transactions. The Fund has entered into an investment advisory agreement (the Advisory Agreement) with the Adviser which provides that the Fund will pay the Adviser a fee, computed daily and paid monthly, at the annual rate of 0.50% of the value of its average daily net assets. In accordance with the Advisory Agreement, the Adviser provides a continuous investment program for the Fund's portfolio, oversees the administration of all aspects of the Fund's business and affairs, and pays the compensation of all Officers and Directors of the Fund who are affiliated persons of the Adviser.

4. Distribution Plan. The Fund's Board has adopted a distribution plan (the Plan) for the Advisor Class Shares pursuant to Rule 12b-1 under the 1940 Act. Under the Advisor Class Share Plan, payment is authorized to G.distributors, LLC (the Distributor), an affiliate of the Adviser, at an annual rate of 0.25% of the average daily net assets of the Advisor Class Shares, the annual limitation under the Plan. Such payments are accrued daily and paid monthly.

5. Portfolio Securities. Purchases and sales of securities during the year ended December 31, 2025, other than short term securities and U.S. Government obligations, aggregated $343,789,022 and $333,839,301, respectively.

6. Transactions with Affiliates and Other Arrangements. During the year ended December 31, 2025, the Fund paid $131,021 in brokerage commissions on security trades to G.research, LLC, an affiliate of the Adviser.

During the year ended December 31, 2025, the Fund received credits from a designated broker who agreed to pay certain Fund operating expenses. The amount of such expenses paid through this directed brokerage arrangement during this period was $8,344.

The Gabelli ABC Fund

Notes to Financial Statements (Continued)

The cost of calculating the Fund's NAV per share is a Fund expense pursuant to the Advisory Agreement. Under the sub-administration agreement with Bank of New York Mellon, the fees paid include the cost of calculating the Fund's NAV. The Fund reimburses the Adviser for this service. During the year ended December 31, 2025, the Fund accrued $45,000 in accounting fees in the Statement of Operations.

As of December 31, 2025, the Fund's Adviser and its affiliates beneficially owned greater than 47% of the voting securities of the Fund. This includes accounts for which the affiliates of the Adviser have voting control but disclaim pecuniary interest.

The Fund pays retainer and per meeting fees to Directors not affiliated with the Adviser, plus specified amounts to the Lead Director and Audit Committee Chairman. Directors are also reimbursed for out of pocket expenses incurred in attending meetings. Directors who are directors or employees of the Adviser or an affiliated company receive no compensation or expense reimbursement from the Fund.

7. Line of Credit. The Fund participates in an unsecured and uncommitted line of credit, which expires on February 25, 2026 and may be renewed annually, of up to $150,000,000 under which it may borrow up to 10% of its net assets from the bank for temporary borrowing purposes. Borrowings under this arrangement bear interest at a floating rate equal to the higher of the Overnight Federal Funds Rate plus 135 basis points or the Overnight Bank Funding Rate plus 135 basis points in effect on that day. This amount, if any, would be included in "Interest expense" in the Statement of Operations. During the year ended December 31, 2025, there were no borrowings under the line of credit.

8. Capital Stock. The Fund offers Class I Shares and Advisor Class Shares to investors without a front-end sales charge. Effective September 29, 2025, Class AAA shares of the Fund were renamed Class I shares. Class I Shares are available directly through the Distributor or through the Fund's transfer agent. Advisor Class Shares are available through registered broker-dealers or other financial intermediaries that have entered into appropriate selling agreements with the Distributor.

The Fund imposes a redemption fee of 2.00% on all classes of shares that are redeemed or exchanged on or before the seventh day after the date of a purchase. The redemption fee is deducted from the proceeds otherwise payable to the redeeming shareholders and is retained by the Fund as an increase in paid-in capital. The redemption fees retained by the Fund during the years ended December 31, 2025 and 2024, if any, can be found in the Statement of Changes in Net Assets under Redemption Fees.

ReFlow Services, LLC. The Fund may participate in the ReFlow Services, LLC liquidity program (ReFlow), which is designed to provide an alternative liquidity source for funds experiencing redemptions. To pay cash to shareholders who redeem their shares on a given day, a fund typically must hold cash in its portfolio, liquidate portfolio securities, or borrow money. ReFlow provides participating funds with another source of cash by standing ready to purchase shares from a fund up to the amount of the fund's net redemptions on a given day, cumulatively limited to 3% of the outstanding voting shares of a fund. ReFlow generally redeems those shares (in cash or in-kind) when the Fund experiences net sales, at the end of a maximum holding period determined by ReFlow, at other times at ReFlow's discretion, or at the direction of the participating fund. In return for this service, a participating fund will pay a fee to ReFlow at a rate determined by a daily auction with other participating mutual funds. This fee, if any, is shown in the Statement of Operations.

During the year ended December 31, 2025 the Fund did not utilize ReFlow.

9. Indemnifications. The Fund enters into contracts that contain a variety of indemnifications. The Fund's maximum exposure under these arrangements is unknown. However, the Fund has not had prior claims or losses pursuant to these contracts. Management has reviewed the Fund's existing contracts and expects the risk of loss to be remote.

10. Segment Reporting. The Fund's Principal Executive Officer and Principal Financial Officer act as the Fund's chief operating decision maker (CODM), as defined in ASC Topic 280, assessing performance and making decisions about resource allocation. The CODM has determined that the Fund has a single operating segment based on the fact that the CODM monitors the operating results of the Fund as a whole and the Fund's long-term strategic asset allocation is guided by the Fund's investment objective and principal investment strategies, and executed by the Fund's portfolio management team, comprised of investment professionals employed by the Adviser. The financial information provided to and reviewed by the CODM is consistent with that presented in the Fund's Schedule of Investments, Statements of Operations and Changes in Net Assets and Financial Highlights.

11. Subsequent Events. On February 25, 2026, the Fund renewed the unsecured and uncommitted line of credit, which expires on April 30, 2026, of up to $150,000,000 under which it may borrow up to 10% of its net assets from the bank for temporary borrowing purposes.

Management has evaluated the impact on the Fund of all subsequent events occurring through the date the financial statements were issued and has determined that there were no other subsequent events requiring recognition or disclosure in the financial statements.

To the Shareholders of The Gabelli ABC Fund

and the Board of Directors of Gabelli Investor Funds, Inc.

Opinion on the Financial Statements

We have audited the accompanying statement of assets and liabilities of Gabelli Investor Funds, Inc. (the "Corporation") (comprising The Gabelli ABC Fund (the "Fund")), including the schedule of investments, as of December 31, 2025, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, the financial highlights for each of the five years in the period then ended and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund comprising Gabelli Investor Funds, Inc. at December 31, 2025, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and its financial highlights for each of the five years in the period then ended, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

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

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

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of December 31, 2025 by correspondence with the custodian, brokers and others; when replies were not received from brokers or others, we performed other auditing procedures. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

We have served as the auditor of one or more Gabelli Funds investment companies since 1992.

Liquidity Risk Management Program (Unaudited)

In accordance with Rule 22e-4 under the 1940 Act,the Fund has established a liquidity risk management program (the LRM Program) to govern its approach to managing liquidity risk. The LRM Program is administered by the Liquidity Committee (the Committee), which is comprised of members of Gabelli Funds, LLC management. The Board has designated the Committee to administer the LRM Program.

The LRM Program's principal objectives include supporting the Fund's compliance with limits on investments in illiquid assets and mitigating the risk that the Fund will be unable to meet its redemption obligations in a timely manner. The LRM Program also includes elements that support the management and assessment of liquidity risk, including an annual assessment of factors that influence the Fund's liquidity and the monthly classification and re-classification of certain investments that reflect the Committee's assessment of their relative liquidity under current market conditions.

At a meeting of the Board held on May 15, 2024, the Board received a written report from the Committee regarding the design and operational effectiveness of the LRM Program. The Committee determined, and reported to the Board, that the LRM Program is reasonably designed to assess and manage the Fund's liquidity risk and has operated adequately and effectively since its implementation. The Committee reported that there were no liquidity events that impacted the Fund or its ability to timely meet redemptions without dilution to existing shareholders. The Committee noted that the Fund is primarily invested in highly liquid securities and, accordingly, continues to be exempt from the requirement to determine a "highly liquid investment minimum" as defined in the Rule 22e-4. Because of that continued qualification for the exemption, the Fund has not adopted a "highly liquid investment minimum" amount. The Committee further noted that while changes to the LRM Program were made during the Review Period and reported to the Board, no material changes were made to the LRM Program as a result of the Committee's annual review.

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

2025 TAX NOTICE TO SHAREHOLDERS (Unaudited)

For the year ended December 31, 2025, the Fund paid to shareholders ordinary income distributions (comprised of net investment income and short term capital gains) totaling $0.3339 and $0.3037 per share for Class I and Advisor Class Shares, respectively, and long term capital gains totaling $6,422,807 or the maximum allowable. The distributions of long term capital gains have been designated as a capital gain dividend by the Fund's Board of Directors. For the year ended December 31, 2025, 32.55% of the ordinary income distribution qualifies for the dividends received deduction available to corporations. The Fund designates 38.63% of the ordinary income distribution as qualified dividend income pursuant to the Jobs and Growth Tax Relief Reconciliation Act of 2003.

U.S. Government Income:

The percentage of the ordinary income distribution paid by the Fund during the year ended December 31, 2025 which was derived from U.S. Treasury securities was 47.02%. Such income is exempt from state and local tax in all states. However, many states, including New York and California, allow a tax exemption for a portion of the income earned only if a mutual fund has invested at least 50% of its assets at the end of each quarter of the Fund's fiscal year in U.S. Government securities. The Fund did not meet this strict requirement in 2025. The percentage of U.S. Government securities held as of December 31, 2025 was 44.1%. Due to the diversity in state and local tax law, it is recommended that you consult your personal tax adviser as to the applicability of the information provided to your specific situation.

All designations are based on financial information available as of the date of this annual report and, accordingly, are subject to change. For each item, it is the intention of the Fund to designate the maximum amount permitted under the Internal Revenue Code and the regulations thereunder.
