**To Our Stockholders,**

For the six months ended March 31, 2026, the net asset value (NAV) total return of The Gabelli Convertible and Income Securities Fund was 0.7%, compared to the total return of 0.7% for the Bloomberg Government/ Credit Bond Index. The total return for the Fund's publicly traded shares was 9.6%. The Fund's NAV per share was $4.14, while the price of the publicly traded shares closed at $4.28 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 March 31, 2026.

**Investment Objective (Unaudited)**

The Gabelli Convertible and Income Securities Fund is a diversified, closed-end management investment company whose primary investment objective is to seek a high level of total return through a combination of current income and capital appreciation.

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)**

During the first fiscal quarter we saw an increase in volatility after a strong 2025. There was a rotation out of AI related names, which had been an important factor in prior performance, but proved to be a headwind to start the year. Convertibles moved higher in the second fiscal quarter, led by breakout performance from a few large equity sensitive issues. Changing interest rate expectations and the implications of the Iran war led to some quarter end weakness, but the market outperformed its underlying equities, which were down through March. This relative outperformance is a typical characteristic of converts in times of volatility and is a key component of the risk adjusted equity exposure we seek for the fund.

Convertible issuance was quite strong in 2025 and that continued through the first half of the fiscal year. Following up on a record year, the first calendar quarter saw a greater pace of issuance in 2026. While this has been a welcome sight for convertible investors, some pricing has been driven by arbitrage demand, leading to lower coupons and higher premiums. We are participating in these issues where appropriate but continue to build our portfolio around balanced convertibles that we believe have asymmetrical upside potential.

At current levels the convertible market offers a YTM of 3.2% and a 36% premium to conversion value. Our portfolio offers a 2.5% YTM at a 29% conversion premium. Sensitivity to moves in underlying equities has increased slightly with the market delta now at 61. GCV's convertible portfolio is slightly more equity sensitive with a delta of 67.At quarter end our portfolio was 24% equity sensitive, 75% total return, and 1% fixed income equivalent. This compares to the market at 41% equity, 32% total return, and 27% fixed income equivalent.

We have managed convertibles through multiple market cycles and remain optimistic about the possibilities of the asset class this year. Our focus on the total return segment of the market allows us to position the portfolio cautiously while participating when the market moves higher. We continue to look for opportunities for equity upside, particularly when market volatility creates attractive entry points.

Top contributors to the portfolio for the first half of 2026 included Lumentum Holdings Inc. 0.375% of '32 (2.3% of net assets as of March 31, 2026), Nova Ltd. 0.0% of '30 (0.9%), and Cohu Inc. 1.5% of '31 (2.0%).

Detractors from performance included Shift4 Payments Inc. (1.1%), Eos Energy Enterprises 1.75% of '31 (no longer held), and Centrus Energy Corp. 0.0% of '32 (1.1%).

Thank you for your investment in The Gabelli Convertible and Income Securities Fund Inc.

We appreciate your confidence and trust.

(a) The Fund's fiscal year ends on September 30.

(b) Performance returns for periods of less than one year are not annualized. Performance 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 Bloomberg Government/Credit Bond Index is a market value weighted index that tracks the performance of fixed rate, publicly placed, dollar denominated obligations. The Lipper Convertible Securities Fund Average reflects the average performance of open-end funds classified in this particular category. Dividends and interest income are considered reinvested. You cannot invest directly in an index.

(c) Total returns and average annual returns reflect changes in the NAV per share, reinvestment of distributions at NAV on the ex-dividend date, and adjustments for rights offerings and are net of expenses. Since inception return is based on an initial NAV of $10.00.

(d) Total returns and average annual returns reflect changes in closing market values on the NYSE, reinvestment of distributions, and adjustments for rights offerings. Since inception return is based on an initial offering price of $11.25 on March 31, 1995.

(e) Since inception return is from March 31, 1995 when the Fund converted to closed-end status; before this date, the Fund had no operating history on the NYSE.

(f) From June 30, 1989, the date closest to the Fund's inception for which data is available.

**The Gabelli Convertible and Income Securities Fund Inc.**

**Notes to Financial Statements (Unaudited)**

**1. Organization.** The Gabelli Convertible and Income Securities Fund(the Fund) was incorporated on December 19, 1988 in Maryland. The Fund is a diversified closed-end management investment company registered under the Investment Company Act of 1940, as amended (the 1940 Act). The investment objective is to seek a high level of total return through a combination of current income and capital appreciation by investing in convertible securities. The Fund commenced investment operations on July 3, 1989. At a special meeting of stockholders held on February 17, 1995, the Board of Directors (the Board) voted to approve the conversion of the Fund to closed-end status, effective March 31, 1995. On February 15, 2023, the Board approved a change of the fiscal year end of the Fund from December 31 to September 30, effective as of September 30, 2023. This report reflects the activity of the Fund for the six months ended March 31, 2026.

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 Funds' investment program and manages the operations of the Fund under the general supervision of the Fund's Board.

**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. 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 securities are valued using the closing bid price, unless the Valuation Designee determines such amount does not reflect the securities' 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 or more dealers in the instrument in question by the Adviser.

**The Gabelli Convertible and Income Securities Fund Inc.**

**Notes to Financial Statements (Unaudited) (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 March 31, 2026 is as follows:

---

(a) Please refer to the Schedule of Investments for the industry classifications of these portfolio holdings.

***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.

**The Gabelli Convertible and Income Securities Fund Inc.**

**Notes to Financial Statements (Unaudited) (Continued)**

***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.

***Series G and Series H Cumulative Preferred Stock.*** For financial reporting purposes only, the liquidation value of preferred stock that has a mandatory call date is classified as a liability within the Statement of Assets and Liabilities and the dividends paid on this preferred stock are included as a component of "Interest expense on preferred stock" within the Statement of Operations. Offering costs are amortized over the life of the preferred stock.

***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

**Notes to Financial Statements (Unaudited) (Continued)**

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 March 31, 2026, 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.

***Custodian Fee Credits.*** 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."

***Distributions to Stockholders.*** Distributions to common stockholders are recorded on the ex-dividend date. Distributions to stockholders 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 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. These reclassifications have no impact on the NAV of the Fund.

The Fund declares and pays quarterly distributions from net investment income, capital gains, and paid-in capital. The actual source of the distribution is determined after the end of the year. Distributions during the year may be made in excess of required distributions. To the extent such distributions are made from current earnings and profits, they are considered ordinary income or long term capital gains. Distributions sourced from paid-in capital should not be considered as dividend yield or the total return from an investment in the Fund. The Board will continue to monitor the Fund's distribution level, taking into consideration the Fund's NAV and the financial market environment. The Fund's distribution policy is subject to modification by the Board at any time.

Distributions to stockholders of the Fund's 5.20% Series H Cumulative Preferred Stock (Series H Preferred) are recorded on a daily basis and are determined as described in Note 7.

**The Gabelli Convertible and Income Securities Fund Inc.**

**Notes to Financial Statements (Unaudited) (Continued)**

The tax character of distributions paid during the fiscal year ended September 30, 2025 was as follows:

---

| | |
|:---|:---|
| **Distributions paid from:** |  |
| Ordinary income (inclusive of short term capital gains) | $9421315 |
| Return of capital | 112471 |
| Total distributions paid | $9533786 |

---

***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 the related net unrealized appreciation at March 31, 2026:

---

| | | | | |
|:---|:---|:---|:---|:---|
|  | **Cost** | **Gross<br> Unrealized<br> Appreciation** | **Gross<br> Unrealized<br> Depreciation** | **Net<br> Unrealized<br> Appreciation** |
| Investments | $80227477 | $12067970 | $(3148155) | $8919815 |

---

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 six months ended March 31, 2026, the Fund did not incur any income tax, interest, or penalties. As of March 31, 2026, 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.

**5. Transactions with Affiliates and Other Arrangements.** During the six months ended March 31, 2026, 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 $657.

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, 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 March 31, 2026, 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). During the six months ended March 31, 2026, the Fund accrued $47,825 in payroll expenses in the Statement of Operations.

The Fund pays each Independent Trustee and certain Interested Trustees retainers and per meeting fees, 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 and uncommitted line of credit of up to $10,000,000 under which it may borrow from the bank for temporary borrowing purposes. Borrowings under this arrangement bear interest at a floating rate based on equal to the higher of the Federal Funds Effective Rate or one-month Secured Overnight Financing Rate (SOFR) 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 March 31, 2026, there were no borrowings under the line of credit.

**7. Capital.** The charter permits the Fund to issue 998,000,000 shares of common stock (par value $0.001). The Board has authorized the repurchase of up to 500,000 shares of common stock on the open market when the shares are trading at a discount of 10% or more (or such other percentage as the Board may determine from time to time) from the NAV of the shares. During the six months ended March 31, 2026 and the fiscal year ended September 30, 2025, the Fund did not repurchase any shares of its common stock in the open market.

For the six months ended March 31, 2026 and the fiscal year ended September 30, 2025, transactions in common stock were as follows:

As of March 31, 2026, the Fund had an effective shelf registration available through September 30, 2027, which authorizes issuance of $125 million in common or preferred shares.

The Fund's Articles of Incorporation authorize the issuance of up to 1,995,000 shares of $0.001 par value Preferred Stock. The Preferred Stock is senior to the common stock and results in the financial leveraging of

**The Gabelli Convertible and Income Securities Fund Inc.**

**Notes to Financial Statements (Unaudited) (Continued)**

the common stock. Such leveraging tends to magnify both the risks and opportunities to common stockholders. Dividends on shares of the Preferred Stock are cumulative. The Fund is required by the 1940 Act and by the Fund's Articles Supplementary to meet certain asset coverage tests with respect to the Preferred Stock. 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 Series G Preferred at the redemption price of $10 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 stockholders 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 rates, which could have either a beneficial or detrimental impact on net investment income and gains available to common stockholders.

On December 29, 2022, the Fund issued 1,500,000 shares of Series G 5.20% Cumulative Preferred Stock, receiving $14,898,306 after the deduction of offering expenses of $101,694. The Series G Preferred has a liquidation value of $10 per share and an annual dividend rate of 5.20%. On December 26, 2023, 860,000 shares of Series G Preferred were put back to the Fund at their liquidation preference of $10 per share. On June 26, 2025, the Fund redeemed all outstanding Series G Preferred at the liquidation preference of $10 per share.

On June 26, 2025, the Fund issued 607,500 shares of Series H 5.20% Cumulative Preferred Stock (Series H Preferred), receiving $6,075,000 after deduction of estimated offering expenses. The Series H Preferred has a liquidation value of $10 per share and an annual dividend rate of 5.20%. The Series H Preferred are subject to mandatory redemption on September 26, 2027. The Series H Preferred are not subject to optional redemption unless such redemption is necessary, in the judgment of the Board, to maintain the Fund's status as a regulated investment company under Subchapter M of the Internal Revenue Code of 1986, as amended. The Fund will also redeem all or any part of the outstanding Series H Preferred that holders have properly tendered for redemption during each sixty day period prior to June 26, 2026, and March 26, 2027, at the liquidation preference, plus any accumulated and unpaid dividends.

The holders of preferred stock generally are entitled to one vote per share held on each matter submitted to a vote of stockholders of the Fund and will vote together with holders of common stock as a single class. The holders of Series H Preferred voting together as a single class also have the right currently to elect two Directors and, under certain circumstances, are entitled to elect a majority of the Board. In addition, the affirmative vote of a majority of the votes entitled to be cast by holders of all outstanding shares of the preferred stock, voting as a single class, will be required to approve any plan of reorganization adversely affecting the preferred stock, 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 stock 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.

**8. Significant Shareholder.** As of March 31, 2026, 9.5% of common shares and 0.0% of the preferred shares were beneficially owned by the Adviser and its affiliates, including 25% or greater holders' managed accounts for which the affiliates of the Adviser have voting control but disclaim pecuniary interest.

**9. Convertible Securities Concentration.** The Fund will invest at least 80% of its net assets, under normal market conditions, in a combination of convertible securities and income producing securities (the 80%

**The Gabelli Convertible and Income Securities Fund Inc.**

**Notes to Financial Statements (Unaudited) (Continued)**

Policy). The Fund expects to continue its practice of focusing on convertible securities to the extent attractive opportunities are available. The 80% Policy may be changed without stockholder approval. However, the Fund has adopted a policy to provide stockholders with notice at least sixty days prior to the implementation of any change in the 80% Policy.

**10. 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.

**11. 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.

**12. Subsequent Events.** 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 subsequent events requiring recognition or disclosure in the financial statements.

**The Gabelli Convertible and Income Securities Fund Inc.**

**Certifications**

The Fund reports to the SEC on Form N-CSR which contains certifications by the Fund's principal executive officer and principal financial officer that relate to the Fund's disclosure in such reports and that are required by Rule 30a-2(a) under the 1940 Act.

**Stockholder Meeting – May 11, 2026 – Final Results**

The Fund's Annual Meeting of Stockholders was held on May 11, 2026. At that meeting, common and preferred stockholders, voting together as a single class, re-elected Vincent D. Enright, Anthonie C. van Ekris, and Salvatore J. Zizza as Directors of the Fund, with 13,202,620 votes, 13,202,994 votes, and 13,198,965 votes cast in favor of these Directors, and 487,066 votes, 486,692 votes, and 490,721 votes withheld for these Directors, respectively.

**Item 11.** **Statement Regarding Basis for Approval of Investment Advisory Contract.**

At its meeting on February 11, 2026 the Board of Directors (Board) of the Fund approved the continuation of the investment advisory agreement with the Adviser for the Fund on the basis of the recommendation by the trustees who are not interested persons of the Fund (the Independent Board Members). The following paragraphs summarize the material information and factors considered by the Independent Board Members as well as their conclusions relative to such factors.

**Nature, Extent and Quality of Services.** The Independent Board Members considered information regarding the portfolio managers, the depth of the analyst pool available to the Adviser and the portfolio managers, the scope of supervisory, administrative, stockholder and other services supervised or provided by the Adviser and the absence of significant service problems reported to the Board. The Independent Board Members noted the experience, length of service and reputation of the portfolio managers.

**Investment Performance.** The Independent Board Members reviewed the performance of the Fund for the one, three, five and ten year periods ended December 31, 2025 against a peer group of eighteen other convertible and total return income oriented funds selected by the Adviser (the "Adviser Peer Group"). The Independent Board Members noted that the Fund's performance was in the first quartile for the one-year period, the third quartile for the three- and ten-year periods, and fourth quartile for the five-year period for the Adviser Peer Group. The Independent Board Members discussed these comparative performance results, noted the Fund's stronger recent performance.

**Profitability.** The Independent Board Members reviewed summary data regarding the profitability of the Fund to the Adviser both with an administrative overhead charge and without such charge. The Board also reviewed materials showing that a portion of the Fund's portfolio transactions was executed by the Adviser's affiliated broker, resulting in incremental profits to the broker.

**Economies of Scale.** The Independent Board Members considered the major elements of the Adviser's cost structure and the relationship of those elements to potential economies of scale. The Independent Board Members noted that the Fund was a closed-end fund and unlikely to realize any economies of scale potentially available through growth in the absence of additional offerings.

**Sharing of Economies of Scale.** The Independent Board Members noted that the investment advisory fee schedule for the Fund does not take into account any potential economies of scale that may develop.

**Service and Cost Comparisons.** The Independent Board Members compared the expense ratios of the investment advisory fee, other expenses, and total expenses of the Fund to similar expense ratios of the Adviser Peer Group and noted that the advisory fee includes substantially all administrative services of the Fund as well as investment advisory services of the Adviser. The Independent Board Members noted that the Fund's effective management fee and total expense ratio were above average, but noted that the Fund's size was below average within the applicable peer groups. The Independent Board Members also noted the effective management fee relative to other funds in the Adviser Peer Group that utilized leverage noting that the Fund's effective management fee was below the average of such funds. The Independent Board Members were presented with information comparing the advisory fee to the fee for other types of accounts managed by the Adviser.

**Conclusions.** The Independent Board Members concluded that the Fund enjoyed highly experienced portfolio management services, good ancillary services and an acceptable performance record within its relatively conservative stance, particularly with respect to long-term performance. The Independent Board Members also concluded that the Fund's expense ratios were acceptable in light of the Fund's size, and that, in part due to the Fund's structure as a closed-end fund, economies of scale were not a significant factor in their thinking. The Independent Board Members did not view the potential profitability of ancillary services as material to their decision. On the basis of the foregoing and without assigning particular weight to any single conclusion, the Independent Board Members determined to recommend continuation of the Advisory Agreement to the full Board.

Based on a consideration of all these factors in their totality, the Board Members, including all of the Independent Board Members, determined that the Fund's advisory fee was appropriate in light of the quality of services provided and in light of the other factors described above that the Board deemed relevant. Accordingly, the Board Members determined to approve the continuation of the Fund's Advisory Agreement. The Board Members based their decision on evaluations of all these factors as a whole and did not consider any one factor as all-important or controlling.
