To Our Shareholders,

For the six months ended June 30, 2024, the net asset value (NAV) total return of The GDL Fund was 2.5%, compared with a total return of 4.3% for the ICE BofA 3 Month U.S. Treasury Bill Index. The total return for the Fund’s publicly traded shares was 0.5%. The Fund’s NAV per share was $10.19, while the price of the publicly traded shares closed at $7.84 on the New York Stock Exchange (NYSE). See page 3 for additional performance information.

Enclosed are the financial statements, including the schedule of investments, as of June 30, 2024.

Investment Objective (Unaudited)

The Fund’s primary investment objective is to achieve absolute returns in various market conditions without excessive risk of capital. The Fund will seek to achieve its objective by investing primarily in merger arbitrage transactions and, to a lesser extent, in corporate reorganizations involving stubs, spin-offs, and liquidations.

As permitted by regulations adopted by the Securities and Exchange Commission, paper copies of the Fund’s annual and semiannual shareholder reports will no longer be sent by mail, unless you specifically request paper copies of the reports. Instead, the reports will be made available on the Fund’s website (www.gabelli.com), and you will be notified by mail each time a report is posted and provided with a website link to access the report. If you already elected to receive shareholder reports electronically, you will not be affected by this change and you need not take any action. To elect to receive all future reports on paper free of charge, please contact your financial intermediary, or, if you invest directly with the Fund, you may call 800-422-3554 or send an email request to info@gabelli.com.

Performance Discussion (Unaudited)

Through the first half of 2024, a total of $1.5 trillion in mergers and acquisitions (M&A) activity was announced globally, with $741 billion announced in the second quarter, representing a nearly 20% increase relative to the second quarter of 2023. Activity within the U.S. accounted for 44% of total deal making in the quarter, totaling $238 billion, stemming from 3,100 deals. Ex-U.S. deal announcements increased 32% quarter over quarter to $412 billion.

Technology, energy and power, and financials were the most active sectors in the first six months, with these three sectors contributing about 48% to total deal volumes. Notable transactions announced in the second quarter included ConocoPhillip’s all-stock transaction to acquire Marathon Oil for nearly $17 billion and International Business Machines acquisition of cloud software company, HashiCorp for $7 billion. Mega deals, or deals greater than $10 billion in value, totaled $363 billion in the first six months of the year, an increase of 70% year-over-year. While deals below $500 million in value declined 28% compared to the same period a year ago.

Overall activity announced by Private Equity buyers totaled $370 billion in the first half of the year, with $216 billion announced in the second quarter, a nearly 40% increase quarter over quarter. This total marked the fourth largest opening six-month period for deals by financial acquirers since records began in 1980.

Companies will gain further clarity into the Federal Reserve’s interest rate policy and the upcoming U.S. presidential election’s potential impact on regulatory changes, but perhaps the main issue that buyers and sellers continue to monitor is the more stringent antitrust environment. Within the U.S. the Federal Trade Commission (FTC) continued its watchful eye on deals in the six months of the year, requesting additional information from merging parties across the energy and healthcare sectors. Deals continue to close as merging parties are drafting strong merger agreements with additional time to consummate deals, in the event of regulatory delays.

The drivers for M&A activity to remain robust over the coming years include the need to compete on a global basis, acquire new technological advancements, and enter new and growing business units.

Selected holdings that contributed positively to performance for the period were: Everbridge, Inc. (2.7% of total investments as of June 30, 2024), an American enterprise software company that offers applications that provide information about critical events to help with personal safety and business continuity; Bel Fuse, Inc. (2.0%), which designs, manufactures, markets, and sells products that power, protect, and connect electronic circuits; and Equitrans Midstream, Corp. (1.6%), which has an operational focus on gas transmission and storage systems, gas gathering systems, and water services that support natural gas development and production.

Some of our weaker performing securities were: Capri Holdings, Ltd. (1.2%), which designs, markets, distributes, and retails branded women’s and men’s apparel, footwear, and accessories in the United States, Canada, Latin America, and Europe; iRobot, Corp. (No longer held as of June 30, 2024), which designs, builds, and sells robots and home innovation products in the United States, Europe, the Middle East, Africa, Japan, and internationally; and TXNM Energy, Inc. (no longer held) through its subsidiaries, provides electricity and electric services in the United States. It operates through the Public Service Company of New Mexico (PNM) and Texas-New Mexico Power Company (TNMP) segments.

Thank you for your investment in The GDL Fund.

We appreciate your confidence and trust.

| (a) | Performance returns for periods of less than one year are not annualized. Returns represent past performance and do not guarantee future results. Investment returns and the principal value of an investment will fluctuate. The Fund’s use of leverage may magnify the volatility of net asset value changes versus funds that do not employ leverage. When shares are sold, they may be worth more or less than their original cost. Current performance may be lower or higher than the performance data presented. Visit www.gabelli.com for performance information as of the most recent month end. The ICE BofA 3 Month U.S. Treasury Bill Index is comprised of a single issue purchased at the beginning of the month and held for a full month. At the end of the month, that issue is sold and rolled into the outstanding Treasury Bill that matures closest to but not beyond three months from the re-balancing date. To qualify for selection, an issue must have settled on or before the re-balancing (month end) date. Dividends are not reinvested for the ICE BofA 3 Month U.S. Treasury Bill Index. You cannot invest directly in an index.

| (b) | Total returns and average annual returns reflect changes in the NAV per share and reinvestment of distributions at NAV on the ex-dividend date and are net of expenses. Since inception return is based on an initial NAV of $19.06.

| (c) | Total returns and average annual returns reflect changes in closing market values on the NYSE and reinvestment of distributions. Since inception return is based on an initial offering price of $20.00.

Investors should carefully consider the investment objectives, risks, charges, and expenses of the Fund before investing.

The GDL Fund

Notes to Financial Statements (Unaudited)

1. Organization. GDL Fund was organized on October 17, 2006 as a Delaware statutory trust. The Fund is a diversified closed-end management investment company registered under the Investment Company Act of 1940, as amended (the 1940 Act). The Fund commenced investment operations on January 31, 2007.

The Fund’s primary investment objective is to achieve absolute returns in various market conditions without excessive risk of capital. The Fund will seek to achieve its objective by investing primarily in merger arbitrage transactions and, to a lesser extent, in corporate reorganizations involving stubs, spin-offs, and liquidations. The Fund will invest at least 80% of its assets, under normal market conditions, in securities or hedging arrangements relating to companies involved in corporate transactions or reorganizations, giving rise to the possibility of realizing gains upon or within relatively short periods of time after the completion of such transactions or reorganizations. The principal risk associated with the Fund’s investment strategy is that certain of the proposed reorganizations in which the Fund invests may involve a longer time frame than originally contemplated or be renegotiated or terminated, in which case losses may be realized. The Fund invests all or a portion of its assets to seek short term capital appreciation. This can be expected to increase the portfolio turnover rate and cause increased brokerage commission costs. The Fund may invest a high percentage of its assets in specific sectors of the market in order to achieve a potentially greater investment return. As a result, the Fund may be more susceptible to economic, political, and regulatory developments in a particular sector of the market, positive or negative, and may experience increased volatility to the Fund’s NAV and a magnified effect in its total return.

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. 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 Board of Trustees (the Board) so determines, by such other method as the Board shall determine in good faith to reflect its fair market value. 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 Gabelli Funds, LLC (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 Board 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 securities are valued using the closing bid price, unless the Board determines such amount does not reflect the securities’ fair value, in which case these securities will be fair valued as determined by the Board. 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

14

The GDL Fund

Notes to Financial Statements (Unaudited) (Continued)

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 or more dealers in the instrument in question by the Adviser.

Securities and assets for which market quotations are not readily available are fair valued as determined by the Board. 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 — 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 June 30, 2024 is as follows:

During the six months ended June 30, 2024, the Fund did not have transfers into or out of Level 3. The Fund’s policy is to recognize transfers among levels as of the beginning of the reporting period.

Additional Information to Evaluate Qualitative Information.

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 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 the options, futures, or swap markets, entails certain execution, liquidity, hedging, tax, and 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. The enforceability of the right to offset may vary by jurisdiction.

The Fund’s derivative contracts held at June 30, 2024, 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. At June 30, 2024, the Fund held no investments in equity contract for difference swap agreements. For the six months ended June 30, 2024, the effect of equity contract for difference swap agreements can

17

Notes to Financial Statements (Unaudited) (Continued)

be found in the Statement of Operations under Net Realized and Unrealized Gain/(Loss) on Investments in securities, Securities Sold Short, Swap Contracts, Forward Foreign Exchange Contracts, and Foreign Currency within Net realized loss on swap contracts.

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 June 30, 2024 are reflected within the Schedule of Investments. The Fund’s volume of activity in forward foreign exchange contracts during the six months ended June 30, 2024 had an average monthly notional amount of approximately $3,645,750.

At June 30, 2024, 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 and under Liabilities, Unrealized depreciation on forward foreign exchange contracts. For the six months ended June 30, 2024, 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, Swap contracts, Forward Foreign Exchange Contracts, and Foreign Currency, within Net realized gain on forward foreign exchange contracts and Net change in unrealized appreciation/depreciation on forward foreign exchange contracts.

Limitations on the Purchase and Sale of Futures Contracts, Certain Options, and Swaps. Subject to the guidelines of the Board, the Fund may engage in “commodity interest” transactions (generally, transactions in futures, certain options, certain currency transactions, and certain types of swaps) only for bona fide hedging or other permissible transactions in accordance with the rules and regulations of the Commodity Futures Trading Commission (CFTC). Pursuant to amendments by the CFTC to Rule 4.5 under the Commodity Exchange Act (CEA), the Adviser has filed a notice of exemption from registration as a “commodity pool operator” with respect to the Fund. The Fund and the Adviser are therefore not subject to registration or regulation as a commodity pool operator under the CEA. In addition, certain trading restrictions are now applicable to the Fund which permit the Fund to engage in commodity interest transactions that include (i) “bona fide hedging” transactions, as that term is defined and interpreted by the CFTC and its staff, without regard to the percentage of the Fund’s assets committed to margin and options premiums and (ii) non-bona fide hedging transactions, provided that the Fund does not enter into such non-bona fide hedging transactions if, immediately thereafter, either (a) the sum of the amount of initial margin deposits on the Fund’s existing futures positions or swaps positions and option or swaption premiums would exceed 5% of the market value of the Fund’s liquidating value, after taking into account unrealized profits and unrealized losses on any such transactions, or (b) the aggregate net notional value of the Fund’s commodity interest transactions would not exceed 100% of the market value of the Fund’s liquidating value, after taking into account unrealized profits and unrealized losses on any such transactions. Therefore, in order to claim the Rule 4.5 exemption, the Fund is limited in its ability to invest in commodity futures, options, and certain types of swaps (including securities futures, broad based stock index futures, and financial futures contracts). As a result, in the future the Fund will be more limited in its ability to use these instruments than in the past, and these limitations may have a negative impact on the ability of the Adviser to manage the Fund, and on the Fund’s performance.

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

19

The GDL Fund

Notes to Financial Statements (Unaudited) (Continued)

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 June 30, 2024 are reflected within the Schedule of Investments. For the six months ended June 30, 2024, the Fund incurred $12,495 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.

Series C and Series E Cumulative Preferred Shares. For financial reporting purposes only, the liquidation value of preferred shares that have a mandatory call date is classified as a liability within the Statement of Assets and Liabilities and the dividends paid on these preferred shares are included as a component of “Interest expense on preferred shares” within the Statement of Operations. Offering costs are amortized over the life of the preferred shares.

Investments in Other Investment Companies. The Fund may invest, from time to time, in shares of other investment companies (or entities that would be considered investment companies but are excluded from the definition pursuant to certain exceptions under the 1940 Act) (the Acquired Funds) in accordance with the 1940 Act and related rules. Shareholders in the Fund would bear the pro rata portion of the periodic expenses of the Acquired Funds in addition to the Fund’s expenses. For the six months ended June 30, 2024, the Fund’s pro rata portion of the periodic expenses charged by the Acquired Funds was less than one basis point.

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.

20

The GDL Fund

Notes to Financial Statements (Unaudited) (Continued)

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 June 30, 2024, the Fund held no 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.

Custodian Fee Credits and Interest Expense. When cash balances are maintained in the custody account, the Fund receives credits which are used to offset custodian fees. The gross expenses paid under the custody arrangement are included in custodian fees in the Statement of Operations with the corresponding expense offset, if any, shown as “Custodian fee credits.” When cash balances are overdrawn, the Fund is charged an overdraft fee of 110% of the 90 day U.S. Treasury Bill rate on outstanding balances. This amount, if any, would be included in the Statement of Operations.

Distributions to Shareholders. Distributions to common 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. See Series C and Series E Cumulative Preferred Shares above for discussion of GAAP treatment. The distributions on these Preferred Shares are treated as dividends for tax purposes. These differences are also 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. These reclassifications have no impact on the NAV of the Fund.

Under the Fund’s current common share distribution policy, the Fund declared and paid quarterly distributions from net investment income, capital gains, and paid-in capital. The actual sources of the distribution are determined after the end of the year. To the extent such distributions were made from current earnings and profits, they are considered ordinary income or long term capital gains. Distributions during the year may be made in excess of required distributions. That portion of a distribution that is paid-in capital (and is not sourced from net investment income or realized gains) should not be considered as the yield or total return on an investment in the Fund.

21

The GDL Fund

Notes to Financial Statements (Unaudited) (Continued)

Distributions to shareholders of the Fund’s Series C and Series E Cumulative Preferred Shares are recorded on a daily basis and are determined as described in Note 7.

The tax character of distributions paid during the year ended December 31, 2023, was as follows:

|  | Common |
Distributions paid from: |  |  |  |
Ordinary income (inclusive of short term capital gains) |  | $ | 2,305,651 |
Net long term capital gains |  |  | 518,763 |
Return of capital |  |  | 3,066,974 |
Total distributions paid |  | $ | 5,891,388 |

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.

The following summarizes the tax cost of investments and derivatives and the related net unrealized appreciation at June 30, 2024:

|  |  |  | Gross |  | Gross |  |
|  | Cost/ |  | Unrealized |  | Unrealized |  | Net Unrealized
|  | (Proceeds) |  | Appreciation |  | Depreciation |  | Appreciation
Investments and other derivative instruments |  | $146,502,297 |  | $9,770,880 |  | $(7,826,304) |  | $1,944,576

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. For the six months ended June 30, 2024, the Fund did not incur any income tax, interest, or penalties. As of June 30, 2024, 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.

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 base fee, computed weekly and paid monthly, equal on an annual basis to 0.50% of the value of the Fund’s average weekly managed assets. Managed assets consist of all of the assets of the Fund without deduction for borrowings, repurchase transactions, and other leveraging techniques, the liquidation value of any outstanding preferred shares, or other liabilities except for certain ordinary course expenses. In addition, the Fund may pay the Adviser an annual performance fee at a calendar year end if the Fund’s total return on its managed assets during the year exceeds the total return of the 3 Month U.S. Treasury Bill Index (the T-Bill Index) during the same period. For every four basis points that the Fund’s total return exceeds the T-Bill Index, the Fund will accrue weekly and pay annually a one basis point performance fee up to a maximum performance fee of 150 basis points. Under the performance fee arrangement, the annual rate of the total fees paid to the Adviser can range

22

The GDL Fund

Notes to Financial Statements (Unaudited) (Continued)

from 0.50% to 2.00% of the average weekly managed assets. During the six months ended June 30, 2024, the Fund did not accrue a performance fee. In accordance with the Advisory Agreement, the Adviser provides a continuous investment program for the Fund’s portfolio and oversees the administration of all aspects of the Fund’s business and affairs.

There was a reduction in the advisory fee paid to the Adviser relating to Bel Fuse, Inc., i.e., unsupervised assets, of the Fund with respect to which the Adviser transferred dispositive and voting control to the Fund’s Proxy Voting Committee. During the six months ended June 30, 2024, the Fund’s Proxy Voting Committee exercised control and discretion over all rights to vote or consent, and exercised dispositive control, with respect to such securities (Bel Fuse), and the Adviser reduced its fee with respect to such securities by $7,858.

4. Portfolio Securities. Purchases and sales of securities during the six months ended June 30, 2024, other than short term securities and U.S. Government obligations, aggregated to $199,959,494 and $160,042,101, respectively. Purchases and sales of U.S. Government Obligations for the six months ended June 30, 2024, aggregated $156,551,827 and $226,439,205, respectively.

5. Transactions with Affiliates and Other Arrangements. During the six months ended June 30, 2024, the Fund paid $39,222 in brokerage commissions on security trades to G.research, LLC, an affiliate of the Adviser.

During the six months ended June 30, 2024, 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 $1,561.

The cost of calculating the Fund’s NAV per share is a Fund expense pursuant to the Advisory Agreement between the Fund and the Adviser. 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 six months ended June 30, 2024, the Fund accrued $22,500 in accounting fees in the Statement of Operations.

As per the approval of the Board, the Fund compensates officers of the Fund, who are employed by the Fund and are not employed by the Adviser (although the officers may receive incentive based variable compensation from affiliates of the Adviser). For the six months ended June 30, 2024, the Fund accrued $125,409 in payroll expenses in the Statement of Operations.

The Fund pays retainer and per meeting fees to Independent Trustees and certain Interested Trustees, plus specified amounts to the Lead Trustee and Audit Committee Chairman. Trustees are also reimbursed for out of pocket expenses incurred in attending meetings. Trustees who are directors or employees of the Adviser or an affiliated company receive no compensation or expense reimbursement from the Fund.

6. Line of Credit. The Fund participates in an unsecured line of credit, which expires on June 25, 2025 and may be renewed annually, of up to $75,000,000 under which it may borrow up to one-third 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 six months ended June 30, 2024, there were no borrowings outstanding under the line of credit.

23

The GDL Fund

Notes to Financial Statements (Unaudited) (Continued)

7. Capital. The Fund is authorized to issue an unlimited number of common shares of beneficial interest (par value $0.001). The Board has authorized the repurchase of the Fund’s common shares on the open market when its shares are trading at a discount of 7.5% or more (or such other percentage as the Board may determine from time to time) from the NAV per share. During the six months ended June 30, 2024 and the year ended December 31, 2023, the Fund repurchased and retired 177,045 and 966,858 common shares in the open market at investments of $1,400,701 and $7,660,676, and an average discounts of approximately 22.21% and 21.68%, respectively, from its NAV.

The Fund has an effective shelf registration authorizing an additional $200 million of common or preferred shares.

The Fund’s Declaration of Trust, as amended, authorizes the issuance of an unlimited number of shares of $0.001 par value Preferred Shares. The Preferred Shares are senior to the common shares and result in the financial leveraging of the common shares. Such leveraging tends to magnify both the risks and opportunities to common shareholders.

The Series C Preferred paid distributions at an annualized rate of 4.00% on the $50 per share liquidation preference for the quarterly dividend periods ended on or prior to March 26, 2019 (Year 1). On February 22, 2019, the Fund’s Board announced a reset fixed dividend rate of 4.00% that will apply for the next eight quarterly dividend periods (Year 2 and Year 3). On March 1, 2021, the Board continued the 4.00% dividend rate for Series C Preferred through the mandatory redemption date of March 26, 2025. On March 26, 2020, 1,935,093 Series C Preferred were put back to the Fund at the liquidation value of $96,754,650, plus accumulated and unpaid dividends. At June 30, 2024, there were 688,932 Series C Preferred outstanding and accrued distributions amounted to $15,310. On March 28, 2022, the Fund issued 3,500,000 shares of Series E Cumulative Term Preferred Shares (Series E Preferred), receiving $34,750,000 after the deduction of offering expenses of $250,000. The Series E Preferred has a liquidation value of $10 per share, and paid dividends at the rate of 4.00% per annum of the $10 per share liquidation preference for the dividend period beginning with the date of original issuance and ending on June 26, 2022 and the three dividend periods thereafter, and 4.25% per annum of the $10 per share liquidation preference for all subsequent dividend periods. The Board of Trustees increased the dividend rate on the Series E Preferred Shares to an annual rate of 5.20% effective January 19, 2023. The Series E Preferred Shares were callable at the Fund’s option on March 26, 2024 and have a mandatory redemption date of March, 26, 2025. On March 27, 2023, 667,500 shares of Series E Preferred were put back to the Fund at their liquidation preference of $10 per share plus accrued and unpaid dividends. On March 27, 2024, 1,545,500 shares of Series E Preferred were put back to the Fund at their liquidation preference of $10 per share plus accrued and unpaid dividends. At June 30, 2024, there were 1,287,000 Series E Preferred outstanding and accrued distributions amounted to $688.

Dividends on the Preferred Shares are cumulative. The Fund is required by the 1940 Act and by the Fund’s Statement of Preferences to meet certain asset coverage tests with respect to the Preferred Shares. If the Fund fails to meet these requirements and does not correct such failure, the Fund may be required to redeem, in part or in full, the Preferred Shares at the respective redemption prices per share plus an amount equal to the accumulated and unpaid dividends whether or not declared on such shares in order to meet these requirements. Additionally, failure to meet the foregoing asset coverage requirements could restrict the Fund’s ability to pay dividends to common shareholders and could lead to sales of portfolio securities at inopportune times. The income received on the Fund’s assets may vary in a manner unrelated to the fixed and variable

24

The GDL Fund

Notes to Financial Statements (Unaudited) (Continued)

rates, which could have either a beneficial or detrimental impact on net investment income and gains available to common shareholders.

The holders of Preferred Shares generally are entitled to one vote per share held on each matter submitted to a vote of shareholders of the Fund and will vote together with holders of common stock as a single class. The holders of Preferred Shares voting together as a single class also have the right currently to elect two Trustees and under certain circumstances are entitled to elect a majority of the Board of Trustees. In addition, the affirmative vote of a majority of the votes entitled to be cast by holders of all outstanding shares of the preferred shares, voting as a single class, will be required to approve any plan of reorganization adversely affecting the preferred shares, and the approval of two-thirds of each class, voting separately, of the Fund’s outstanding voting stock must approve the conversion of the Fund from a closed-end to an open-end investment company. The approval of a majority (as defined in the 1940 Act) of the outstanding preferred shares and a majority (as defined in the 1940 Act) of the Fund’s outstanding voting securities are required to approve certain other actions, including changes in the Fund’s investment objectives or fundamental investment policies.
