(4)Principal is net of repayments. Cost is net of repayments and accumulated unearned income. Negative cost is the result of the capitalized discount being greater than the principal amount outstanding on the loan.

(5)"Control" investments are defined by the 1940 Act (as defined below) as investments in which more than 25% of the voting securities are owned or where the ability to nominate greater than 50% of the board representation is maintained.

(6)"Affiliate" investments are defined by the 1940 Act as investments in which between 5% and 25% (inclusive) of the voting securities are owned and the investments are not classified as Control investments.

(7)"Non-Control/Non-Affiliate" investments are defined by the 1940 Act as investments that are neither Control investments nor Affiliate investments.

(8)Income producing through dividends or distributions.

(9)Index based floating interest rate is subject to contractual minimum interest rate. As noted in this schedule, 97% of the loans (based on the par amount) contain Secured Overnight Financing Rate ("SOFR") floors which range between 0.75% and 5.25%, with a weighted-average floor of 1.30%.

(10)Private Loan (as defined below) portfolio investment. See *Note C — Fair Value Hierarchy for Investments — Portfolio Composition* for a description of Private Loan portfolio investments.

(11)Middle Market (as defined below) portfolio investment. See *Note C — Fair Value Hierarchy for Investments — Portfolio Composition* for a description of Middle Market portfolio investments.

(12)Other Portfolio (as defined below) investment. See *Note C — Fair Value Hierarchy for Investments — Portfolio Composition* for a description of Other Portfolio investments.

(13)Investment is not a qualifying asset as defined under Section 55(a) of the 1940 Act (as defined below). Qualifying assets must represent at least 70% of total assets at the time of acquisition of any additional non-qualifying assets.

(14)Non-accrual or non-income producing debt investment.

(15)All of the Fund's portfolio investments are generally subject to restrictions on resale as "restricted securities."

(16)Effective yield as of March 31, 2026 was approximately 3.55% on the First American Treasury Obligations Fund Class Z.

(17)Maturity date is under on-going negotiations with the portfolio company and other lenders, if applicable.

(18)Investment Fair Value was determined using significant unobservable inputs, unless otherwise noted. See *Note C — Fair Value Hierarchy for Investments — Portfolio Composition* for further discussion. Negative fair value is the result of the capitalized discount on the loan or the unfunded commitment being valued below par.

(19)Investments may have a portion, or all, of their income received from Paid-in-Kind ("PIK") interest or dividends. PIK interest income and cumulative dividend income represent income not paid currently in cash. The difference between the Total Rate and PIK Rate represents the cash rate as of March 31, 2026.

(20)All portfolio company headquarters are based in the U.S., unless otherwise noted.

(21)Portfolio company headquarters are located outside of the U.S.

(22)Investment Date represents the date of initial investment in the security position.

(23)Shares/Units represent ownership in a related real estate or holding entity.

(24)Investment is not unitized. Presentation is made in percent of fully diluted ownership unless otherwise indicated.

(25)A majority of the variable rate loans in the Investment Portfolio (as defined below) bear interest at a rate that may be determined by reference to either SOFR ("SF") or an alternate base rate (commonly based on the federal funds rate or the Prime rate ("P")), which typically resets every one, three, or six months at the borrower's option. SOFR based contracts may include a credit spread adjustment (the "Adjustment") that is charged in addition to the stated spread. The Adjustment is applied when the SOFR, plus the Adjustment, exceeds the stated floor rate, as applicable. As of March 31, 2026, SOFR based contracts in the portfolio had Adjustments ranging from 0.10% to 0.26%.

(26)Each new draw or funding on the facility has a different floating rate reset date. The rate presented represents a weighted-average rate for borrowings under the facility, as of March 31, 2026.

(27)Warrants are presented in equivalent shares/units with a strike price of $0.01 per share/unit.

(28)Revolving line of credit facility permits the borrower to make an interest rate election regarding the base rate on each draw under the facility. The rate presented represents a weighted-average rate for borrowings under the facility, as of March 31, 2026.

(29)Index based floating interest rate is subject to contractual maximum base rate of 3.00%.

(30)The position is unfunded and no interest income is being earned as of March 31, 2026. The position may earn a nominal unused facility fee on committed amounts.

(31)Effective yield as of March 31, 2026 was approximately 3.28% on the Fidelity Government Portfolio Fund Class III.

(32)Index based floating interest rate is subject to contractual maximum base rate of 4.00%.

(33)The Fund has entered into an intercreditor agreement that entitles the Fund to the "last out" tranche of the first lien secured loans, whereby the "first out" tranche will receive priority as to the "last out" tranche with respect to payments of principal, interest, and any other amounts due thereunder. Therefore, the Fund receives a higher interest rate than the contractual stated interest rate of 11.80% per the credit agreement and the Consolidated Schedule of Investments above reflects such higher rate.

(2)Debt investments are income producing, unless otherwise noted by footnote (14), as described below. Equity and warrants are non-income producing, unless otherwise noted by footnote (8), as described below.

(3)*See Note C — Fair Value Hierarchy for Investments — Portfolio Composition* and Schedule 12-14 for a summary of geographic location of portfolio companies.

(4)Principal is net of repayments. Cost is net of repayments and accumulated unearned income. Negative cost is the result of the capitalized discount being greater than the principal amount outstanding on the loan.

(6)"Affiliate" investments are defined by the 1940 Act as investments in which between 5% and 25% (inclusive) of the voting securities are owned and the investments are not classified as Control investments.

(7)"Non-Control/Non-Affiliate" investments are defined by the 1940 Act as investments that are neither Control investments nor Affiliate investments.

(8)Income producing through dividends or distributions.

(9)Index based floating interest rate is subject to contractual minimum interest rate. As noted in this schedule, 97% of the loans (based on the par amount) contain SOFR floors which range between 0.75% and 5.25%, with a weighted-average floor of 1.31%.

(16)Effective yield as of December 31, 2025 was approximately 3.67% on the First American Treasury Obligations Fund Class Z.

(17)Maturity date is under on-going negotiations with the portfolio company and other lenders, if applicable.

(18)Investment Fair Value was determined using significant unobservable inputs, unless otherwise noted. See *Note C — Fair Value Hierarchy for Investments — Portfolio Composition* for further discussion. Negative fair value is the result of the capitalized discount on the loan or the unfunded commitment being valued below par.

(19)Investments may have a portion, or all, of their income received from PIK interest or dividends. PIK interest income and cumulative dividend income represent income not paid currently in cash. The difference between the Total Rate and PIK Rate represents the cash rate as of December 31, 2025.

(20)All portfolio company headquarters are based in the U.S., unless otherwise noted.

(21)Portfolio company headquarters are located outside of the U.S.

(22)Investment Date represents the date of initial investment in the security position.

(23)Shares/Units represent ownership in a related real estate or holding entity.

(24)Investment is not unitized. Presentation is made in percent of fully diluted ownership unless otherwise indicated.

(25)A majority of the variable rate loans in the Investment Portfolio bear interest at a rate that may be determined by reference to either SOFR ("SF") or an alternate base rate (commonly based on the federal funds rate or the Prime rate ("P")), which typically resets every one, three, or six months at the borrower's option. SOFR based contracts may include a credit spread adjustment (the "Adjustment") that is charged in addition to the stated spread. The Adjustment is applied when the SOFR, plus the Adjustment, exceeds the stated floor rate, as applicable. As of December 31, 2025, SOFR based contracts in the portfolio had Adjustments ranging from 0.10% to 0.26%.

(26)Each new draw or funding on the facility has a different floating rate reset date. The rate presented represents a weighted-average rate for borrowings under the facility, as of December 31, 2025.

(27)Warrants are presented in equivalent shares/units with a strike price of $0.01 per share/unit.

(28)Revolving line of credit facility permits the borrower to make an interest rate election regarding the base rate on each draw under the facility. The rate presented represents a weighted-average rate for borrowings under the facility, as of December 31, 2025.

(29)Index based floating interest rate is subject to contractual maximum base rate of 3.00%.

(30)The position is unfunded and no interest income is being earned as of December 31, 2025. The position may earn a nominal unused facility fee on committed amounts.

(31)Investment is accruing income at the fixed cash rate of 2.50% as of December 31, 2025.

(32)Index based floating interest rate is subject to contractual maximum base rate of 4.00%.

(33)The Fund has entered into an intercreditor agreement that entitles the Fund to the "last out" tranche of the first lien secured loans, whereby the "first out" tranche will receive priority as to the "last out" tranche with respect to payments of principal, interest, and any other amounts due thereunder. Therefore, the Fund receives a higher interest rate than the contractual stated interest rate of 11.80% per the credit agreement and the Consolidated Schedule of Investments above reflects such higher rate.

(34)Effective yield as of December 31, 2025 was approximately 3.42% on the Fidelity Government Portfolio Fund Class III.

**MSC INCOME FUND, INC.**

**Notes to the Consolidated Financial Statements**

**(Unaudited)**

**NOTE A — ORGANIZATION AND BASIS OF PRESENTATION**

**1. Organization**

MSC Income Fund, Inc. ("MSIF" or, together with its consolidated subsidiaries, "MSC Income" or the "Fund") is a principal investment firm primarily focused on providing debt capital to private ("Private Loan") companies owned by or in the process of being acquired by a private equity fund (its "Private Loan investment strategy"). MSC Income's portfolio investments are typically made to support leveraged buyouts, recapitalizations, growth financings, refinancings and acquisitions of companies that operate in diverse industry sectors. MSC Income seeks to partner with private equity fund sponsors in its Private Loan investment strategy and primarily invests in secured debt investments of Private Loan companies generally headquartered in the U.S.

MSC Income also maintains a portfolio of customized long-term debt and equity investments in lower middle market ("LMM") companies (its "LMM investment portfolio"), and through those investments MSC Income has partnered with entrepreneurs, business owners and management teams in co-investments with Main Street Capital Corporation ("Main Street"), a New York Stock Exchange ("NYSE") listed business development company ("BDC"), utilizing the customized "one-stop" debt and equity financing solutions provided in Main Street's LMM investment strategy (the "LMM investment strategy"). Through the LMM investment strategy, MSC Income primarily invested in secured debt investments, equity investments, warrants and other securities of LMM companies typically based in the U.S. Effective upon the MSC Income Listing (as defined below) on January 29, 2025, MSC Income changed its investment strategy for investments in new portfolio companies to be solely focused on its Private Loan investment strategy, rather than its historical focus primarily on the Private Loan investment strategy and secondarily on the LMM investment strategy (as further discussed below).

MSC Income also maintains a legacy portfolio of investments in larger middle market ("Middle Market") companies (its "Middle Market investment portfolio") and a limited portfolio of other portfolio ("Other Portfolio") investments. MSC Income's Middle Market investments are generally debt investments in companies owned by a private equity fund that were originally issued through a syndication financing process. MSC Income has generally stopped making new Middle Market investments and expects the size of its Middle Market investment portfolio to continue to decline in future periods as its existing Middle Market investments are repaid or sold. MSC Income's Other Portfolio investments primarily consist of investments that are not consistent with the typical profiles for its Private Loan, LMM or Middle Market portfolio investments, including investments in unaffiliated investment companies and private funds managed by third parties. Similar to its Middle Market investments, MSC Income has generally stopped making new Other Portfolio investments and expects the size of its Other Portfolio to continue to decline in future periods as its existing Other Portfolio investments are repaid or sold.

The "Investment Portfolio," as used herein, refers to all of MSC Income's investments in Private Loan portfolio companies, investments in LMM portfolio companies, investments in Middle Market portfolio companies and Other Portfolio investments.

MSIF was formed in November 2011 to operate as an externally managed BDC under the Investment Company Act of 1940, as amended (the "1940 Act"). MSIF has elected to be treated for U.S. federal income tax purposes as a regulated investment company ("RIC") under Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code"). As a result, MSIF generally does not pay corporate-level U.S. federal income taxes on any net ordinary taxable income or capital gains that it distributes to its stockholders.

On October 28, 2020, MSC Income's stockholders approved the appointment of MSC Adviser I, LLC (the "Adviser"), which is wholly-owned by Main Street, as MSC Income's investment adviser and administrator under an Investment Advisory and Administrative Services Agreement dated October 30, 2020 (the "Prior Investment Advisory Agreement").

On January 29, 2025, MSC Income's shares of common stock were listed on the NYSE under the ticker symbol "MSIF" (the "MSC Income Listing").

**(Unaudited)**

On January 29, 2025, in connection with the MSC Income Listing, MSC Income entered into an Amended and Restated Investment Advisory and Administrative Services Agreement (the "Advisory Agreement") with the Adviser. The Advisory Agreement was approved by the affirmative vote of the holders of a majority of MSC Income's outstanding voting securities, as defined in the 1940 Act, at a special meeting of MSC Income's stockholders held on December 11, 2024 (the "2024 Special Meeting"), and the Advisory Agreement became effective upon the MSC Income Listing. In such role, the Adviser has the responsibility to manage the business of MSC Income, including the responsibility to identify, evaluate, negotiate and structure prospective investments, make investment and portfolio management decisions, monitor its Investment Portfolio and provide ongoing administrative services.

On January 29, 2025, in connection with the MSC Income Listing, the Fund amended and restated its Articles of Amendment and Restatement, as amended, by filing new Articles of Amendment and Restatement of the Fund (the "New Articles") with the State Department of Assessments and Taxation of the State of Maryland. The New Articles revised the Fund's charter to, among other things, (i) include a provision that limits the transferability of shares of its common stock outstanding at the time of the MSC Income Listing during the 365-day period following the MSC Income Listing, (ii) reflect an amendment to delete provisions regarding restrictions and requirements applicable to its DRIP (as defined below), (iii) reflect an amendment to delete provisions prohibiting acquisitions of assets in exchange for shares of its common stock and restricting certain transactions between the Fund and the Adviser and its affiliates and (iv) delete certain provisions required by, and remove references to, the NASAA Guidelines in order to conform certain provisions of the Fund's charter more closely to provisions in the charters of other BDCs whose securities are listed and publicly-traded on a national securities exchange.

On January 30, 2025, in connection with the MSC Income Listing, MSC Income closed a follow-on public offering of 5,500,000 shares of its common stock, at the public offering price of $15.53 per share. In addition, on February 3, 2025, MSC Income issued and sold 825,000 additional shares of its common stock, at the public offering price of $15.53 per share, pursuant to the underwriters' full exercise of their overallotment option (together with the offering and sale of the 5,500,000 shares, the "MSC Income Offering"). Net of underwriting discounts and commissions and offering costs, the Fund received net cash proceeds of $90.5 million in connection with the MSC Income Offering.

MSIF has certain direct and indirect wholly-owned subsidiaries that have elected to be taxable entities (the "Taxable Subsidiaries"). The primary purpose of the Taxable Subsidiaries is to permit MSIF to hold equity investments in portfolio companies which are "pass-through" entities for tax purposes. MSIF also has certain direct and indirect wholly-owned subsidiaries formed for financing purposes (the "Structured Subsidiaries").

Unless otherwise noted or the context otherwise indicates, the terms "MSC Income" and the "Fund" refer to MSIF and its consolidated subsidiaries, which include the Taxable Subsidiaries and the Structured Subsidiaries.

**2. Basis of Presentation**

MSC Income's consolidated financial statements are prepared in accordance with generally accepted accounting principles in the United States of America ("U.S. GAAP"). The Fund is an investment company following accounting and reporting guidance in Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 946, *Financial Services—Investment Companies* ("ASC 946"). For each of the periods presented herein, MSC Income's consolidated financial statements include the accounts of MSIF and its consolidated subsidiaries. MSC Income's results of operations for the three months ended March 31, 2026 and 2025, cash flows for the three months ended March 31, 2026 and 2025 and financial position as of March 31, 2026 and December 31, 2025 are presented on a consolidated basis. The effects of all intercompany transactions between MSIF and its consolidated subsidiaries have been eliminated in consolidation.

**Notes to the Consolidated Financial Statements (Continued)**

**(Unaudited)**

The accompanying unaudited consolidated financial statements of MSC Income are presented in conformity with U.S. GAAP for interim financial information and pursuant to the requirements for reporting on Form 10-Q and Articles 6, 10 and 12 of Regulation S-X. Accordingly, certain disclosures accompanying annual consolidated financial statements prepared in accordance with U.S. GAAP are omitted. The unaudited consolidated financial statements and notes should be read in conjunction with the audited consolidated financial statements and notes thereto for the year ended December 31, 2025. In the opinion of management, the unaudited consolidated financial results included herein contain all adjustments, consisting solely of normal recurring accruals, considered necessary for the fair presentation of financial statements for the interim periods included herein. The results of operations for the three months ended March 31, 2026 are not necessarily indicative of the operating results to be expected for the full year. Financial statements prepared on a U.S. GAAP basis require management to make estimates and assumptions that affect the amounts and disclosures reported in the consolidated financial statements and accompanying notes. Such estimates and assumptions could change in the future as more information becomes known, which could impact the amounts reported and disclosed herein.

***Principles of Consolidation***

Under ASC 946, MSC Income is precluded from consolidating other entities in which MSC Income has equity investments, including those in which it has a controlling interest, unless the other entity is another investment company. An exception to this general principle in ASC 946 occurs if MSC Income holds a controlling interest in an operating company that provides all or substantially all of its services directly to MSC Income. Accordingly, as noted above, MSC Income's consolidated financial statements include the financial position and operating results for the Taxable Subsidiaries and the Structured Subsidiaries. MSC Income has determined that none of its portfolio investments qualify for this exception. Therefore, MSC Income's Investment Portfolio is carried on the Consolidated Balance Sheets at fair value (see *Note B.1. — Summary of Significant Accounting Policies — Valuation of the Investment Portfolio* below) with any adjustments to fair value recognized as "Net Unrealized Appreciation (Depreciation)" until the investment is realized, usually upon exit, resulting in any gain or loss being recognized as a "Net Realized Gain (Loss)," in both cases, on the Consolidated Statements of Operations.

***Portfolio Investment Classification***

MSC Income classifies its Investment Portfolio in accordance with the requirements of the 1940 Act. Under the 1940 Act, (a) "Control" investments are defined as investments in which MSC Income owns more than 25% of the voting securities or has rights to maintain greater than 50% of the board representation, (b) "Affiliate" investments are defined as investments in which MSC Income owns between 5% and 25% (inclusive) of the voting securities and does not have rights to maintain greater than 50% of the board representation and (c) "Non-Control/Non-Affiliate" investments are defined as investments that are neither Control investments nor Affiliate investments. For purposes of determining the classification of its Investment Portfolio, MSC Income has excluded consideration of any voting securities or board appointment rights held by Main Street or any other advisory clients of the Adviser.

**NOTE B — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES**

**1. Valuation of the Investment Portfolio**

MSC Income accounts for its Investment Portfolio at fair value. As a result, MSC Income follows the provisions of ASC 820, *Fair Value Measurements and Disclosures* ("ASC 820"). ASC 820 defines fair value, establishes a framework for measuring fair value, establishes a fair value hierarchy based on the quality of inputs used to measure fair value and enhances disclosure requirements for fair value measurements. ASC 820 requires MSC Income to assume that the portfolio investment is to be sold in the principal market to independent market participants, which may be a hypothetical market. Market participants are defined as buyers and sellers in the principal market that are independent, knowledgeable and willing and able to transact.

**Notes to the Consolidated Financial Statements (Continued)**

**(Unaudited)**

MSC Income's investment strategy calls for it to invest primarily in debt securities issued by Private Loan companies. MSC Income also maintains its LMM investment portfolio and its investment strategy calls for it to invest in future follow-on investments in illiquid debt and equity securities issued by its existing LMM portfolio companies, as or if such opportunities exist. Effective on the date of the MSC Income Listing, the Fund changed its investment strategy with respect to new platform investments to be solely focused on the Private Loan investment strategy. As a result, the size of the LMM investment portfolio is expected to decrease over time as existing LMM investments are repaid or sold in the ordinary course of business. MSC Income also maintains a legacy portfolio of investments in Middle Market companies and a limited portfolio of Other Portfolio investments which are also expected to decrease over time as MSC Income is generally no longer making new Middle Market investments or Other Portfolio investments. MSC Income's portfolio investments may be subject to restrictions on resale.

Private Loan investments may include investments which have no established market or have established markets that are not active, while LMM investments and Other Portfolio investments generally have no established trading market. Middle Market portfolio investments generally have established markets that are not active. MSC Income determines in good faith the fair value of its Investment Portfolio pursuant to a valuation policy in accordance with ASC 820, with such valuation process approved by its Board of Directors and in accordance with the 1940 Act. MSC Income's valuation policies and processes are intended to provide a consistent basis for determining the fair value of MSC Income's Investment Portfolio.

For Private Loan and Middle Market portfolio investments in debt securities for which it has determined that third-party quotes or other independent pricing are not available or appropriate, MSC Income generally estimates the fair value based on the assumptions that it believes hypothetical market participants would use to value the investment in a current hypothetical sale using the yield-to-maturity model ("Yield-to-Maturity") valuation method. For LMM portfolio investments, MSC Income generally reviews external events, including private mergers, sales and acquisitions involving comparable companies, and includes these events in the valuation process by using an enterprise value waterfall ("Waterfall") valuation method for its LMM equity investments and an income approach using a Yield-to-Maturity valuation method for its LMM debt investments. For Middle Market portfolio investments in debt securities for which it has determined that third-party quotes or other independent prices are available, MSC Income primarily uses quoted prices in the valuation process. MSC Income determines the appropriateness of the use of third-party broker quotes, if any, in determining fair value based on its understanding of the level of actual transactions used by the broker to develop the quote and whether the quote was an indicative price or binding offer, the depth and consistency of broker quotes and the correlation of changes in broker quotes with underlying performance of the portfolio company and other market indices. For its Other Portfolio equity investments, MSC Income generally calculates the fair value of the investment primarily based on the net asset value ("NAV") of the investment fund and adjusts the fair value for other factors deemed relevant that would affect the fair value of the investment. All of the valuation approaches for MSC Income's portfolio investments estimate the value of the investment as if MSC Income were to sell, or exit, the investment as of the measurement date.

These valuation approaches consider the value associated with MSC Income's ability to control the capital structure of the portfolio company, as well as the timing of a potential exit. For valuation purposes, "control" portfolio investments are composed of debt and equity securities in companies for which MSC Income has a controlling interest in the equity ownership of the portfolio company or the ability to nominate a majority of the portfolio company's board of directors. For valuation purposes, "non-control" portfolio investments are generally composed of debt and equity securities in companies for which MSC Income does not have a controlling interest in the equity ownership of the portfolio company or the ability to nominate a majority of the portfolio company's board of directors.

**(Unaudited)**

Under the Waterfall valuation method, MSC Income estimates the enterprise value of a portfolio company using a combination of market and income approaches or other appropriate valuation methods, such as considering recent transactions in the equity securities of the portfolio company or third-party valuations of the portfolio company, and then performs a Waterfall calculation by allocating the enterprise value over the portfolio company's securities in order of their preference relative to one another. The enterprise value is the fair value at which an enterprise could be sold in a transaction between two willing parties, other than through a forced or liquidation sale. Typically, privately held companies are bought and sold based on multiples of earnings before interest, taxes, depreciation and amortization ("EBITDA"), cash flows, net income, revenues, or in limited cases, book value. There is no single methodology for estimating enterprise value. For any one portfolio company, enterprise value is generally described as a range of values from which a single estimate of enterprise value is derived. In estimating the enterprise value of a portfolio company, MSC Income analyzes various factors including the portfolio company's historical and projected financial results. Due to Securities and Exchange Commission ("SEC") deadlines for MSC Income's quarterly and annual financial reporting, the operating results of a portfolio company used in the current period valuation are generally the results from the period ended three months prior to such valuation date and may include unaudited, projected, budgeted or pro forma financial information and may require adjustments for non-recurring items or to normalize the operating results that may require significant judgment in determining. In addition, projecting future financial results requires significant judgment regarding future growth assumptions. In evaluating the operating results, MSC Income also analyzes the impact of exposure to litigation, loss of customers or other contingencies. After determining the appropriate enterprise value, MSC Income allocates the enterprise value to investments in order of the legal priority of the various components of the portfolio company's capital structure. In applying the Waterfall valuation method, MSC Income assumes the loans are paid-off at the principal amount in a change in control transaction and are not assumed by the buyer, which MSC Income believes is consistent with its past transaction history and standard industry practices.

Under the Yield-to-Maturity valuation method, MSC Income also uses the income approach to determine the fair value of debt securities based on projections of the discounted future free cash flows that the debt security will likely generate, including analyzing the discounted cash flows of interest and principal amounts for the debt security, as set forth in the associated loan agreements, as well as the financial position and credit risk of the portfolio company. MSC Income's estimate of the expected repayment date of its debt securities is generally the maturity date of the instrument, as MSC Income generally intends to hold its loans and debt securities to maturity. The Yield-to-Maturity analysis also considers changes in leverage levels, credit quality, portfolio company performance, changes in market-based interest rates and other factors. MSC Income will generally use the value determined by the Yield-to-Maturity analysis as the fair value for that security; however, because of MSC Income's general intent to hold its loans to maturity, the fair value will not exceed the principal amount of the debt security valued using the Yield-to-Maturity valuation method. A change in the assumptions that MSC Income uses to estimate the fair value of its debt securities using the Yield-to-Maturity valuation method could have a material impact on the determination of fair value. If there is deterioration in credit quality or if a debt security is in workout status, MSC Income may consider other factors in determining the fair value of the debt security, including the value attributable to the debt security from the enterprise value of the portfolio company or the proceeds that would most likely be received in a liquidation analysis.

Under the NAV valuation method, for an investment in an investment fund that does not have a readily determinable fair value, MSC Income measures the fair value of the investment predominately based on the NAV of the investment fund as of the measurement date and adjusts the investment's fair value for factors known to MSC Income that would affect that fund's NAV, including, but not limited to, fair values for individual investments held by the fund if MSC Income holds the same investment or for a publicly traded investment. In addition, in determining the fair value of the investment, MSC Income considers whether adjustments to the NAV are necessary in certain circumstances, based on the analysis of any restrictions on redemption of MSC Income's investment as of the measurement date, recent actual sales or redemptions of interests in the investment fund, and expected future cash flows available to equity holders, including the rate of return on those cash flows compared to an implied market return on equity required by market participants, or other uncertainties surrounding MSC Income's ability to realize the full NAV of its interests in the investment fund.

Pursuant to its internal valuation process and the requirements under the 1940 Act, MSC Income performs valuation procedures on each of its portfolio investments quarterly. In addition to its internal valuation process, in arriving at estimates of fair value for its investments in its Private Loan portfolio companies, MSC Income, among other things, consults with a nationally recognized independent financial advisory services firm (the "Financial Advisory Firm"). The Financial Advisory Firm analyzes and provides observations, recommendations and an assurance certification regarding MSC Income's determinations of the fair value of its Private Loan portfolio company investments. The Financial Advisory Firm is generally consulted relative to MSC Income's investments in each Private Loan portfolio company at least once every calendar year, and for MSC Income's investments in new Private Loan portfolio companies, at least once in the twelve-month period subsequent to the initial investment. In certain instances, MSC Income may determine that it is not cost-effective, and as a result is not in its stockholders' best interest, to consult with the Financial Advisory Firm on its investments in one or more Private Loan portfolio companies. Such instances include, but are not limited to, situations where the fair value of MSC Income's investment in a Private Loan portfolio company is determined to be insignificant relative to the total Investment Portfolio. MSC Income consulted with and received an assurance certification from the Financial Advisory Firm in arriving at its determination of fair value for its investments in a total of 15 and 13 Private Loan portfolio companies as of March 31, 2026 and 2025, respectively, representing 30% and 26% of the total Private Loan portfolio at fair value as of March 31, 2026 and 2025, respectively. A total of 60 Private Loan portfolio companies were reviewed and certified by the Financial Advisory Firm as of the end of a fiscal quarter during the trailing twelve months ended March 31, 2026, representing 83% of the total Private Loan portfolio at fair value as of March 31, 2026. Excluding its investments in Private Loan portfolio companies that, as of March 31, 2026, had not been in the Investment Portfolio for at least twelve months subsequent to the initial investment, 97% of the Private Loan portfolio at fair value was reviewed and certified by the Financial Advisory Firm during the trailing twelve months ended March 31, 2026.

For valuation purposes, all of MSC Income's Private Loan portfolio investments are non-control investments. For Private Loan portfolio investments for which it has determined that third-party quotes or other independent pricing are not available or appropriate, MSC Income generally estimates the fair value based on the assumptions that it believes hypothetical market participants would use to value such Private Loan debt investments in a current hypothetical sale using the Yield-to-Maturity valuation method and such Private Loan equity investments in a current hypothetical sale using the Waterfall valuation method.

In addition to its internal valuation process, in arriving at estimates of fair value for its investments in its LMM portfolio companies, MSC Income, among other things, consults with the Financial Advisory Firm. The Financial Advisory Firm analyzes and provides observations, recommendations and an assurance certification regarding MSC Income's determinations of the fair value of its LMM portfolio company investments. The Financial Advisory Firm is generally consulted relative to MSC Income's investments in each LMM portfolio company at least once every calendar year, and for MSC Income's investments in new LMM portfolio companies, at least once in the twelve-month period subsequent to the initial investment. In certain instances, MSC Income may determine that it is not cost-effective, and as a result is not in its stockholders' best interest, to consult with the Financial Advisory Firm on its investments in one or more LMM portfolio companies. Such instances include, but are not limited to, situations where the fair value of MSC Income's investment in a LMM portfolio company is determined to be insignificant relative to the total Investment Portfolio. MSC Income consulted with and received an assurance certification from the Financial Advisory Firm in arriving at its determination of fair value for its investments in a total of 13 and 12 LMM portfolio companies as of March 31, 2026 and 2025, respectively, representing 30% and 26% of the total LMM portfolio at fair value as of March 31, 2026 and 2025, respectively. A total of 48 LMM portfolio companies were reviewed and certified by the Financial Advisory Firm as of the end of a fiscal quarter during the trailing twelve months ended March 31, 2026, representing 96% of the total LMM portfolio at fair value as of March 31, 2026. Excluding its investments in LMM portfolio companies whose primary purpose is to own real estate for which a third-party appraisal is obtained on at least an annual basis, 99% of the LMM portfolio at fair value was reviewed and certified by the Financial Advisory Firm during the trailing twelve months ended March 31, 2026.

**Notes to the Consolidated Financial Statements (Continued)**

**(Unaudited)**

For valuation purposes, all of MSC Income's Middle Market portfolio investments are non-control investments. To the extent sufficient observable inputs are available to determine fair value, MSC Income uses observable inputs to determine the fair value of these investments through obtaining third-party quotes or other independent pricing. For Middle Market portfolio investments for which it has determined that third-party quotes or other independent pricing are not available or appropriate, MSC Income generally estimates the fair value based on the assumptions that it believes hypothetical market participants would use to value such Middle Market debt investments in a current hypothetical sale using the Yield-to-Maturity valuation method and such Middle Market equity investments in a current hypothetical sale using the Waterfall valuation method. MSC Income generally consults on a limited basis with the Financial Advisory Firm in connection with determining the fair value of its Middle Market portfolio investments due to the nature of these investments. The vast majority (86% and 85% as of March 31, 2026 and December 31, 2025, respectively) of the Middle Market portfolio investments (i) are valued using third-party quotes or other independent pricing services or (ii) MSC Income has consulted with and received an assurance certification from the Financial Advisory Firm within the last twelve months.

For valuation purposes, all of MSC Income's Other Portfolio investments are non-control investments. MSC Income's Other Portfolio investments comprised 1.1% and 1.2% of MSC Income's Investment Portfolio at fair value as of March 31, 2026 and December 31, 2025, respectively. Similar to the LMM investment portfolio, market quotations for Other Portfolio equity investments are generally not readily available. For its Other Portfolio equity investments, MSC Income generally determines the fair value of these investments using the NAV valuation method.

Due to the inherent uncertainty in the valuation process, MSC Income's determination of fair value for its Investment Portfolio may differ materially from the values that would have been determined had a ready market for the securities existed. In addition, changes in the market environment, portfolio company performance and other events that may occur over the lives of the investments may cause the gains or losses ultimately realized on these investments to be materially different than the valuations currently assigned. MSC Income determines the fair value of each individual investment and records changes in fair value as unrealized appreciation or depreciation.

MSC Income uses an internally developed portfolio investment rating system in connection with its investment oversight, portfolio management and analysis and investment valuation procedures for its Private Loan, LMM and Middle Market portfolio companies. This system takes into account both quantitative and qualitative factors of each Private Loan, LMM and Middle Market portfolio company.

Rule 2a-5 under the 1940 Act permits a BDC's board of directors to designate its executive officers or investment adviser as a valuation designee to determine the fair value for its investment portfolio, subject to the active oversight of the board. MSC Income's Board of Directors has approved policies and procedures pursuant to Rule 2a-5 (the "Valuation Procedures") and has designated the Adviser, led by a group of its executive officers, to serve as the Board of Directors' valuation designee. MSC Income believes its Investment Portfolio as of March 31, 2026 and December 31, 2025 approximates fair value as of those dates based on the markets in which it operates and other conditions in existence on those reporting dates.

**2. Use of Estimates**

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expenses during the period. Actual results may differ from these estimates under different conditions or assumptions. Additionally, as explained in *Note B.1. — Summary of Significant Accounting Policies — Valuation of the Investment Portfolio*, the consolidated financial statements include investments in the Investment Portfolio whose values have been estimated by MSC Income, pursuant to the Valuation Procedures, in the absence of readily ascertainable market values. Because of the inherent uncertainty of the Investment Portfolio valuations, those estimated values may differ materially from the values that would have been determined had a ready market for the securities existed.

**(Unaudited)**

Macroeconomic factors, including pandemics, risk of recession, inflation, supply chain constraints or disruptions, geopolitical disruptions, uncertainty with respect to the imposition of tariffs on and trade disputes with certain countries and changing market index interest rates, and the related effect on the U.S. and global economies, have impacted, and may continue to impact, the businesses and operating results of certain of MSC Income's portfolio companies. As a result of these and other current effects of macroeconomic factors, as well as the uncertainty regarding the extent and duration of their impact, the valuation of MSC Income's Investment Portfolio has and may continue to experience increased volatility.

**3. Cash and Cash Equivalents**

Cash and cash equivalents consist of cash and highly liquid investments with an original maturity of three months or less at the date of purchase. Cash and cash equivalents are carried at cost, which approximates fair value. As of March 31, 2026 and December 31, 2025, the Fund had $8.7 million and $11.1 million, respectively, of cash equivalents invested in AAA-rated money market funds pending investment in the Fund's primary investment strategies. These highly liquid investments are included in the Consolidated Schedule of Investments.

As of March 31, 2026 and December 31, 2025, cash balances totaling $5.9 million and $8.5 million, respectively, exceeded Federal Deposit Insurance Corporation insurance protection levels, subjecting the Fund to risk related to the uninsured balance.

**4. Interest, Dividend and Fee Income**

MSC Income records interest and dividend income on the accrual basis to the extent amounts are expected to be collected. Dividend income is recorded when dividends are declared by the portfolio company or at such other time that an obligation exists for the portfolio company to make a distribution. MSC Income evaluates accrued interest and dividend income periodically for collectability. When a loan or debt security becomes 90 days or more past due, and if MSC Income otherwise does not expect the debtor to be able to service its debt obligation, MSC Income will generally place the loan or debt security on non-accrual status and cease recognizing interest income on that loan or debt security until the borrower has demonstrated the ability and intent to pay contractual amounts due. If a loan or debt security's status significantly improves regarding the debtor's ability to service the debt obligation, or if a loan or debt security is sold or written off, MSC Income removes it from non-accrual status. Generally, any interest payments received for investments on non-accrual status reduce the cost basis of the investment and are not recorded as income.

As of March 31, 2026, investments on non-accrual status were $15.1 million at fair value and $55.0 million at cost and comprised 1.1% and 4.2% of MSC Income's total Investment Portfolio at fair value and cost, respectively. As of December 31, 2025, investments on non-accrual status were $13.7 million at fair value and $49.0 million at cost and comprised 1.0% and 3.9% of MSC Income's total Investment Portfolio at fair value and cost, respectively.

MSC Income holds certain debt and preferred equity instruments in its Investment Portfolio that contain PIK interest and cumulative dividend provisions. The PIK interest, computed at the contractual rate specified in each debt agreement, is periodically added to the principal balance of the debt and is recorded as interest income. Thus, the actual collection of this interest may be deferred until the time of debt principal repayment. Cumulative dividends are recorded as dividend income, and any dividends in arrears are added to the balance of the preferred equity investment. The actual collection of these dividends in arrears may be deferred until such time as the preferred equity is redeemed or sold. To maintain RIC tax treatment (see *Note B.8. — Summary of Significant Accounting Policies — Income Taxes* below), these non-cash sources of income may need to be paid out to stockholders in the form of distributions, even though MSC Income may not have collected the PIK interest and cumulative dividends in cash. MSC Income stops accruing PIK interest and cumulative dividends and writes off any accrued and uncollected interest and dividends in arrears when it determines that such PIK interest and dividends in arrears are no longer collectible. For the three months ended March 31, 2026 and 2025, (i) 7.3% and 5.8%, respectively, of MSC Income's total investment income was attributable to PIK interest income not paid currently in cash and (ii) 0.8% and 0.2%, respectively, of MSC Income's total investment income was attributable to cumulative dividend income not paid currently in cash.

MSC Income may periodically provide services, including structuring and advisory services, to its portfolio companies or other third parties. For services that are separately identifiable and evidence exists to substantiate fair value, fee income is recognized as earned, which is generally when the investment or other applicable transaction closes. Fees received in connection with debt financing transactions for services that do not meet these criteria are treated as debt origination fees and are generally deferred and accreted into income over the life of the financing.

A presentation of total investment income MSC Income earned from its Investment Portfolio in each of the periods presented is as follows:

**5. Deferred Financing Costs**

Deferred financing costs include commitment fees and other direct costs incurred in connection with arranging MSC Income's borrowings. Deferred financing costs incurred in connection with the Credit Facilities (as defined in *Note D — Debt*) are capitalized as an asset. Deferred financing costs incurred in connection with the October 2026 Notes and the May 2029 Notes (as defined in *Note D — Debt*) are reflected as a direct deduction from the principal amount outstanding.

**6. Equity Offering Costs**

The Fund's offering costs are charged against the proceeds from equity offerings when the proceeds are received.

**7. Unearned Income — Debt Origination Fees and Original Issue Discount and Discounts / Premiums to Par Value**

MSC Income capitalizes debt origination fees received in connection with financings and reflects such fees as unearned income netted against the applicable debt investments. The unearned income from the fees is accreted into income over the life of the financing.

In connection with its portfolio debt investments, MSC Income sometimes receives nominal cost warrants or warrants with an exercise price below the fair value of the underlying equity (together, "nominal cost equity") that are valued as part of the negotiation process with the particular portfolio company. When MSC Income receives nominal cost equity, it allocates its cost basis in its investment between its debt security and its nominal cost equity at the time of origination based on amounts negotiated with the particular portfolio company. The allocated amounts are based upon the fair value of the nominal cost equity, which is then used to determine the allocation of cost to the debt security. Any discount recorded on a debt investment resulting from this allocation is reflected as unearned income, which is netted against the applicable debt investment, and accreted into interest income over the life of the debt investment. The actual collection of this interest is deferred until the time of debt principal repayment.

MSC Income may also purchase debt securities at a discount or at a premium to the par value of the debt security. In the case of a purchase at a discount, MSC Income records the investment at the par value of the debt security net of the discount, and the discount is accreted into interest income over the life of the debt investment. In the case of a purchase at a premium, MSC Income records the investment at the par value of the debt security plus the premium, and the premium is amortized as a reduction to interest income over the life of the debt investment.

**(Unaudited)**

To maintain RIC tax treatment (see *Note B.8. — Summary of Significant Accounting Policies — Income Taxes* below), these non-cash sources of income may need to be paid out to stockholders in the form of distributions, even though MSC Income may not have collected the interest income. For the three months ended March 31, 2026 and 2025, 2.6% and 2.3%, respectively, of MSC Income's total investment income was attributable to interest income from the accretion of discounts associated with debt investments, net of any premium amortization.

**8. Income Taxes**

MSIF has elected to be treated for U.S. federal income tax purposes as a RIC. MSIF's taxable income includes the taxable income generated by MSIF and certain of its subsidiaries, including the Structured Subsidiaries, which are treated as disregarded entities for tax purposes. As a RIC, MSIF generally will not pay corporate-level U.S. federal income taxes on any net ordinary taxable income or capital gains that MSIF distributes to its stockholders. MSIF must generally distribute at least 90% of its "investment company taxable income" (which is generally its net ordinary taxable income and realized net short-term capital gains in excess of realized net long-term capital losses) and 90% of its tax-exempt income to maintain its RIC status (pass-through tax treatment for amounts distributed). As part of maintaining RIC status, undistributed taxable income (subject to a 4% non-deductible U.S. federal excise tax) pertaining to a given fiscal year may be distributed up to twelve months subsequent to the end of that fiscal year, provided such dividends are declared on or prior to the later of (i) the filing of the U.S. federal income tax return for the applicable fiscal year or (ii) the fifteenth day of the ninth month following the close of the year in which such taxable income was generated.

The Taxable Subsidiaries primarily hold certain equity investments for MSC Income. The Taxable Subsidiaries permit MSC Income to hold equity investments in portfolio companies which are "pass-through" entities for tax purposes and to continue to comply with the "source-of-income" requirements contained in the RIC tax provisions of the Code. The Taxable Subsidiaries are consolidated with MSC Income for U.S. GAAP financial reporting purposes, and the portfolio investments held by the Taxable Subsidiaries are included in MSC Income's consolidated financial statements as portfolio investments and recorded at fair value. The Taxable Subsidiaries are not consolidated with MSIF for income tax purposes and may generate income tax expense, or benefit, and tax assets and liabilities, as a result of their ownership of certain portfolio investments. The taxable income, or loss, of the Taxable Subsidiaries may differ from their book income, or loss, due to temporary book and tax timing differences and permanent differences. The Taxable Subsidiaries are each taxed at corporate income tax rates based on their taxable income. The income tax expense, or benefit, if any, and the related tax assets and liabilities, of the Taxable Subsidiaries are reflected in MSC Income's consolidated financial statements.

The Taxable Subsidiaries use the liability method in accounting for income taxes. Deferred tax assets and liabilities are recorded for temporary differences between the tax basis of assets and liabilities and their reported amounts in the consolidated financial statements, using statutory tax rates in effect for the year in which the temporary differences are expected to reverse. A valuation allowance is provided, if necessary, against deferred tax assets when it is more likely than not that some portion or all of the deferred tax asset will not be realized. MSC Income's net assets as included on the Consolidated Balance Sheets and Consolidated Statements of Changes in Net Assets include an adjustment to classification as a result of permanent book-to-tax differences, which include differences in the book and tax treatment of income and expenses.

Taxable income generally differs from net income for financial reporting purposes due to temporary and permanent differences in the recognition of income and expenses. Taxable income generally excludes net unrealized appreciation or depreciation, as investment gains or losses are not included in taxable income until they are realized.

**9. Net Realized Gains or Losses and Net Unrealized Appreciation or Depreciation**

Realized gains or losses are measured by the difference between the net proceeds from the sale or redemption of an investment or a financial instrument and the cost basis of the investment or financial instrument, without regard to unrealized appreciation or depreciation previously recognized, and includes investments written-off during the period net of recoveries and realized gains or losses from in-kind redemptions. Net unrealized appreciation or depreciation reflects the net change in the fair value of the Investment Portfolio and financial instruments and the reclassification of any prior period unrealized appreciation or depreciation on exited investments and financial instruments to realized gains or losses.

**10. Fair Value of Financial Instruments**

Fair value estimates are made at discrete points in time based on relevant information. These estimates may be subjective in nature and involve uncertainties and matters of significant judgment and, therefore, cannot be determined with precision. MSC Income believes that the carrying amounts of its financial instruments, consisting of cash and cash equivalents, receivables, payables and other liabilities approximate the fair values of such items due to the short-term nature of these instruments.

MSC Income's debt instruments, including all revolving and term debt, are accounted for on a historical cost basis as applicable under U.S. GAAP. As also required under U.S. GAAP, MSC Income discloses the estimated fair value of its debt obligations in *Note D — Debt.* To estimate the fair value of MSC Income's October 2026 Notes and May 2029 Notes as disclosed in *Note D — Debt*, MSC Income uses the Yield-to-Maturity valuation method based on projections of the discounted future free cash flows that the debt security will likely generate, including both the discounted cash flows of the associated interest and principal amounts for the debt security. The inputs used to value MSC Income's debt instruments for purposes of the fair value estimate disclosures in *Note D — Debt* are considered to be Level 2 according to the ASC 820 fair value hierarchy.

**11. Earnings Per Share**

Basic and diluted per share calculations, including net increase in net assets resulting from operations per share and net investment income per share, are computed utilizing the weighted-average number of shares of common stock outstanding for the period.

**12. Segments**

MSC Income operates as a single segment with a principal investment objective to maximize total return, primarily by generating current income from debt investments and, to a lesser extent, by generating current income and capital appreciation from equity and equity-related investments. The Adviser's Investment Committee and the Fund's Chief Executive Officer collectively perform the function that allocates resources and assesses performance, and thus together, serve as the Fund's chief operating decision maker (the "CODM"). Among other metrics, the CODM uses net investment income as a primary U.S. GAAP profit or loss metric used in making operating decisions, which can be found on the Consolidated Statement of Operations along with significant expenses. The measure of segment assets is reported on the Consolidated Balance Sheets as total assets.

**13. Recently Issued or Adopted Accounting Standards**

From time to time, new accounting pronouncements are issued by the FASB or other standards-setting bodies that are adopted by the Fund as of the specified effective date. The Fund believes that the impact of recently issued standards and any that are not yet effective will not have a material impact on its consolidated financial statements upon adoption.

**NOTE C — FAIR VALUE HIERARCHY FOR INVESTMENTS — PORTFOLIO COMPOSITION**

ASC 820 defines fair value, establishes a framework for measuring fair value, establishes a fair value hierarchy based on the quality of inputs used to measure fair value, and enhances disclosure requirements for fair value measurements. MSC Income accounts for its investments at fair value.

**Fair Value Hierarchy**

In accordance with ASC 820, MSC Income has categorized its investments based on the priority of the inputs to the valuation technique into a three-level fair value hierarchy. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical investments (Level 1) and the lowest priority to unobservable inputs (Level 3).

Investments recorded on MSC Income's Consolidated Balance Sheets are categorized based on the inputs to the valuation techniques as follows:

Level 1 — Investments whose values are based on unadjusted quoted prices for identical assets in an active market that MSC Income has the ability to access (examples include investments in active exchange-traded equity securities and investments in most U.S. government and agency securities).

**MSC INCOME FUND, INC.**

**Notes to the Consolidated Financial Statements (Continued)**

**(Unaudited)**

Level 2 — Investments whose values are based on quoted prices in markets that are not active or model inputs that are observable either directly or indirectly for substantially the full term of the investment. Level 2 inputs include the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Quoted prices for similar assets in active markets (for example, investments in restricted stock);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Quoted prices for identical or similar assets in non-active markets (for example, investments in thinly traded public companies);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Pricing models whose inputs are observable for substantially the full term of the investment (for example, market interest rate indices); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Pricing models whose inputs are derived principally from, or corroborated by, observable market data through correlation or other means for substantially the full term of the investment.

Level 3 — Investments whose values are based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement (for example, investments in illiquid securities issued by privately held companies). These inputs reflect management's own assumptions about the assumptions a market participant would use in pricing the investment.

As required by ASC 820, when the inputs used to measure fair value fall within different levels of the hierarchy, the level within which the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measurement in its entirety. For example, a Level 3 fair value measurement may include inputs that are observable (Levels 1 and 2) and unobservable (Level 3). Therefore, unrealized appreciation and depreciation related to such investments categorized within the Level 3 tables below may include changes in fair value that are attributable to both observable inputs (Levels 1 and 2) and unobservable inputs (Level 3).

As of March 31, 2026 and December 31, 2025, all of MSC Income's Private Loan portfolio investments consisted of illiquid securities issued by privately held companies. The fair value determination for these investments consisted of a combination of observable inputs in non-active markets for which sufficient observable inputs were not available to determine the fair value of these investments and unobservable inputs. As a result, all of MSC Income's Private Loan portfolio investments were categorized as Level 3 as of March 31, 2026 and December 31, 2025.

As of March 31, 2026 and December 31, 2025, all of MSC Income's LMM portfolio investments consisted of illiquid securities issued by privately held companies and the fair value determination for these investments primarily consisted of unobservable inputs. As a result, all of MSC Income's LMM portfolio investments were categorized as Level 3 as of March 31, 2026 and December 31, 2025.

As of March 31, 2026 and December 31, 2025, MSC Income's Middle Market portfolio investments consisted primarily of investments in secured and unsecured debt investments and independently rated debt investments. The fair value determination for these investments consisted of a combination of observable inputs in non-active markets for which sufficient observable inputs were not available to determine the fair value of these investments and unobservable inputs. As a result, all of MSC Income's Middle Market portfolio investments were categorized as Level 3 as of March 31, 2026 and December 31, 2025.

As of March 31, 2026 and December 31, 2025, all of MSC Income's Other Portfolio investments consisted of illiquid securities issued by privately held entities and the fair value determination for these investments primarily consisted of unobservable inputs. As a result, all of MSC Income's Other Portfolio investments were categorized as Level 3 as of March 31, 2026 and December 31, 2025.

As of March 31, 2026 and December 31, 2025, all money market funds included in cash and cash equivalents were valued using Level 1 inputs.

The fair value determination of each portfolio investment categorized as Level 3 required one or more of the following unobservable inputs:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Financial information obtained from each portfolio company, including unaudited statements of operations and balance sheets for the most recent period available as compared to budgeted financial information;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Current and projected financial condition of the portfolio company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Current and projected ability of the portfolio company to service its debt obligations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Type and amount of collateral, if any, underlying the investment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Current financial ratios (e.g., fixed charge coverage ratio, interest coverage ratio and net debt/EBITDA ratio) applicable to the investment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Current liquidity of the investment and related financial ratios (e.g., current ratio and quick ratio);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Pending debt or capital restructuring of the portfolio company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Projected operating results of the portfolio company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Current information regarding any offers to purchase the investment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Current ability of the portfolio company to raise any additional financing as needed;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Changes in the economic environment which may have a material impact on the operating results of the portfolio company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Internal occurrences that may have an impact (both positive and negative) on the operating performance of the portfolio company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Qualitative assessment of key management;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Contractual rights, obligations or restrictions associated with the investment; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Other factors deemed relevant.

The use of significant unobservable inputs creates uncertainty in the measurement of fair value as of the reporting date. The significant unobservable inputs used in the fair value measurement of MSC Income's LMM equity securities, which are generally valued through an average of the discounted cash flow technique and the market comparable/enterprise value technique (unless one of these approaches is determined to not be appropriate), are (i) EBITDA multiples and (ii) the weighted-average cost of capital ("WACC"). Significant increases (decreases) in EBITDA multiple inputs in isolation would result in a significantly higher (lower) fair value measurement, and significant increases (decreases) in WACC inputs in isolation would result in a significantly lower (higher) fair value measurement. The significant unobservable inputs used in the fair value measurement of MSC Income's Private Loan, LMM and Middle Market debt securities are (i) risk adjusted discount rates used in the Yield-to-Maturity valuation technique (see *Note B.1. — Summary of Significant Accounting Policies — Valuation of the Investment Portfolio*) and (ii) the percentage of expected principal recovery. Significant increases (decreases) in any of these discount rates in isolation would result in a significantly lower (higher) fair value measurement. Significant increases (decreases) in any of these expected principal recovery percentages in isolation would result in a significantly higher (lower) fair value measurement. However, due to the nature of certain investments, fair value measurements may be based on other criteria, such as third-party appraisals of collateral and fair values as determined by independent third parties, which are not presented in the tables below.

**Investment Portfolio Composition**

MSC Income's principal investment objective is to maximize its portfolio's total return, primarily by generating current income from its debt investments and, to a lesser extent, by generating current income and capital appreciation from its equity and equity-related investments, including warrants, convertible securities and other rights to acquire equity securities in a portfolio company. MSC Income seeks to achieve its investment objective primarily through its Private Loan investment strategy and secondarily through its LMM investment portfolio.

MSC Income's Private Loan investment strategy is focused on investments in secured debt in privately held companies that generally have annual revenues between $25 million and $500 million, and its Private Loan investments generally range in size from $1 million to $30 million. MSC Income's Private Loan investments primarily consist of debt securities that have primarily been originated directly by the Adviser or, to a lesser extent, through the Adviser's strategic relationships with other investment funds on a collaborative basis through investments that are often referred to in the debt markets as "club deals" because of the small lender group size. In both cases, MSC Income's Private Loan investments are typically made in a company owned by or in the process of being acquired by a private equity fund. MSC Income's Private Loan portfolio debt investments are generally secured by a first priority lien on the assets of the portfolio company and typically have a term of between three and seven years from the original investment date. MSC Income may also co-invest with Main Street and the private equity fund in the equity securities of its Private Loan portfolio companies.

**Notes to the Consolidated Financial Statements (Continued)**

**(Unaudited)**

MSC Income maintains a LMM investment portfolio with investments in secured debt and equity investments in privately held, LMM companies based in the U.S. MSC Income's LMM portfolio companies generally have annual revenues between $10 million and $150 million, and its LMM investments generally range in size from $1 million to $30 million. The LMM portfolio debt investments are generally secured by a first priority lien on the assets of the portfolio company, can include either fixed or floating interest rates and generally have a term of between five and seven years from the original investment date. MSC Income typically makes direct equity investments and/or receives nominally priced equity warrants in connection with a LMM portfolio company debt investment.

In connection with the MSC Income Listing, the Fund changed its investment strategy with respect to new platform investments to be solely focused on the Private Loan investment strategy. As a result, the size of the Fund's LMM investment portfolio is expected to decrease over time as existing LMM investments are repaid or sold in the ordinary course of business. The Fund does, however, plan to continue executing follow-on investments in its existing LMM portfolio companies going forward in accordance with its existing SEC order for co-investment exemptive relief.

MSC Income also maintains a legacy portfolio of investments in Middle Market companies. MSC Income's Middle Market investments are generally debt investments in companies owned by a private equity fund that were originally issued through a syndication financing process. MSC Income has generally stopped making new Middle Market investments and expects the size of its Middle Market investment portfolio to continue to decline in future periods as its existing Middle Market investments are repaid or sold. MSC Income's Middle Market debt investments generally range in size from $1 million to $20 million, are generally secured by a first priority lien on the assets of the portfolio company and typically have an expected duration of between three and seven years from the original investment date.

MSC Income's Other Portfolio investments primarily consist of investments that are not consistent with the typical profiles for its Private Loan, LMM or Middle Market portfolio investments, including investments in unaffiliated investment companies and private funds managed by third parties. In the Other Portfolio, MSC Income may incur indirect fees and expenses in connection with investments managed by third parties, such as investments in other investment companies or private funds. For Other Portfolio investments, MSC Income generally receives distributions related to the assets held by the portfolio company. Those assets are typically expected to be realized over a five to ten-year period. Similar to its Middle Market investments, the Fund has generally stopped making new Other Portfolio investments and expects the size of its Other Portfolio to continue to decline in future periods as existing Other Portfolio investments are repaid or sold.

Based upon MSC Income's liquidity and capital structure management activities, MSC Income's Investment Portfolio may also periodically include short-term portfolio investments that are atypical of MSC Income's Private Loan and LMM portfolio investments in that they are intended to be a short-term deployment of capital. Those assets are typically expected to be realized in one year or less. These short-term portfolio investments are not expected to be a significant portion of the overall Investment Portfolio.

Investment income, consisting of interest, dividends and fees, can fluctuate dramatically due to various factors, including the level of new investment activity, repayments of debt investments or sales of equity interests. Investment income in any given year could also be highly concentrated among several portfolio companies. For the three months ended March 31, 2026 and 2025, MSC Income did not record investment income from any single portfolio company in excess of 10% of total investment income.

A summary of MSC Income's Private Loan and LMM portfolio investments as of March 31, 2026 and December 31, 2025 is as follows (this information excludes Middle Market and Other Portfolio investments, which are discussed further below):

| Weighted-average annual effective yield (b) | 10.5% | 12.6% |
| Average EBITDA (c) | $30.6 | $12.1 |

___________________

(a)As of March 31, 2026, MSC Income had equity ownership in all of its LMM portfolio companies, and the average fully diluted equity ownership in those portfolio companies was 8%.

(b)The weighted-average annual effective yields were computed using the effective interest rates for all debt investments as of March 31, 2026, including amortization of deferred debt origination fees and accretion of original issue discount but excluding fees payable upon repayment of the debt investments and any debt investments on non-accrual status, and are weighted based upon the principal amount of each applicable debt investment as of March 31, 2026. The weighted-average annual effective yield on MSC Income's debt portfolio as of March 31, 2026, including debt investments on non-accrual status, was 10.1% for its Private Loan portfolio investments and 11.9% for its LMM portfolio investments. The weighted-average annual effective yield is not reflective of what an investor in shares of MSC Income's common stock will realize on their investment because it does not reflect changes in the market value of MSC Income's stock, MSC Income's utilization of debt capital in its capital structure, MSC Income's expenses or any sales load paid by an investor.

(c)The average EBITDA is calculated using a weighted-average for Private Loan portfolio companies and a simple average for LMM portfolio companies. These calculations exclude certain portfolio companies, including four Private Loan portfolio companies and three LMM portfolio companies, as EBITDA is not a meaningful valuation metric for MSC Income's investments in these portfolio companies, and those portfolio companies whose primary purpose is to own real estate and those portfolio companies whose primary operations have ceased and only residual value remains.

The weighted-average annual effective yield on MSC Income's debt portfolio as of December 31, 2025, including debt investments on non-accrual status, was 10.3% for its Private Loan portfolio investments and 11.7% for its LMM portfolio investments. The weighted-average annual effective yield is not reflective of what an investor in shares of MSC Income's common stock will realize on their investment because it does not reflect changes in the market value of MSC Income's stock, MSC Income's utilization of debt capital in its capital structure, MSC Income's expenses or any sales load paid by an investor.

For the three months ended March 31, 2026 and 2025, MSC Income achieved an annualized total return on investments of 9.8% and 10.6%, respectively. For the year ended December 31, 2025, MSC Income achieved a total return on investments of 13.9%. Total return on investments equals the total interest, dividend and fee income plus realized and unrealized changes in the fair value of the Investment Portfolio divided by the average quarterly Investment Portfolio balance at cost, in each case for the specified period. MSC Income's total return on investments is not reflective of what an investor in shares of MSC Income's common stock will realize on their investment because it does not reflect changes in the market value of MSC Income's stock, MSC Income's utilization of debt capital in its capital structure, MSC Income's expenses or any sales load paid by an investor.

As of March 31, 2026, MSC Income had Middle Market portfolio investments in eight portfolio companies, collectively totaling $23.0 million in fair value and $40.3 million in cost basis, which comprised 1.7% and 3.1% of MSC Income's Investment Portfolio at fair value and cost, respectively.

**Unconsolidated Significant Subsidiaries**

In accordance with Rules 3-09 and 4-08(g) of Regulation S-X, MSC Income must determine which of its unconsolidated controlled portfolio companies, if any, are considered "significant subsidiaries." In evaluating its unconsolidated controlled portfolio companies in accordance with Regulation S-X, there are two tests that MSC Income must utilize to determine if any of MSC Income's Control investments (as defined in *Note A — Organization and Basis of Presentation*), including those unconsolidated portfolio companies defined as Control investments in which MSC Income does not own greater than 50% of the voting securities nor have rights to maintain greater than 50% of the board representation, are considered significant subsidiaries: the investment test and the income test. The investment test is generally measured by dividing the fair value of MSC Income's investment in the Control investment by the fair value of MSC Income's total investments. The income test is generally measured by dividing the absolute value of the combined sum of total investment income, net realized gain (loss) and net unrealized appreciation (depreciation) from the relevant Control investment for the period being tested by the absolute value of MSC Income's change in net assets resulting from operations for the same period. Rules 3-09 and 4-08(g) of Regulation S-X require MSC Income to include (1) separate audited financial statements of an unconsolidated majority-owned subsidiary (Control investments in which MSC Income owns greater than 50% of the voting securities) in an annual report and (2) summarized financial information of a Control investment in a quarterly report, respectively, if certain thresholds of the investment or income tests are exceeded and the unconsolidated portfolio company qualifies as a significant subsidiary.

As of March 31, 2026 and December 31, 2025, MSC Income had no single investment that qualified as a significant subsidiary under either the investment or income tests.

**(Unaudited)**

**SPV Facility**

MSC Income, through MSIF Funding, LLC ("MSIF Funding"), a wholly-owned Structured Subsidiary that primarily holds debt investments, maintains a special purpose vehicle revolving credit facility dated February 3, 2021 (as amended, the "SPV Facility") with JPMorgan Chase Bank, National Association ("JPM"), as administrative agent, and U.S. Bank, N.A., as collateral agent and collateral administrator, JPM and other financial institutions as lenders and MSIF as portfolio manager.

As of March 31, 2026, the SPV Facility included (i) total commitments of $300.0 million, (ii) an accordion feature with the right to request an increase of total commitments and borrowing availability up to $450.0 million and (iii) a revolving period through February 2029 and a final maturity date in February 2030. As of March 31, 2026, advances under the SPV Facility bore interest at a rate equal to the applicable SOFR in effect, plus a margin of 2.20%. MSIF Funding also pays a commitment fee of 0.75% on the average daily unused amount of the financing commitments until February 2029. The SPV Facility is secured by a first lien on the assets of MSIF Funding. Borrowing availability under the SPV Facility is subject to certain leverage and borrowing base limitations, covenants, reporting and other requirements customary for similar credit facilities.

As of March 31, 2026, the interest rate for borrowings on the SPV Facility was 5.86%. The average interest rate for borrowings under the SPV Facility was 5.86% and 7.24% for the three months ended March 31, 2026 and 2025, respectively. As of March 31, 2026, MSC Income was in compliance with all financial covenants of the SPV Facility.

**Corporate Facility**

MSC Income maintains a senior secured revolving credit agreement dated March 6, 2017 (as amended, the "Corporate Facility") with EverBank, as administrative agent, and with EverBank and other financial institutions as lenders.

As of March 31, 2026, the Corporate Facility included (i) total commitments of $245.0 million from a diversified group of seven lenders, (ii) an accordion feature with the right to request an increase in commitments under the facility from new and existing lenders on the same terms and conditions as the existing commitments up to $300.0 million of total commitments and (iii) a revolving period through November 2028 and a final maturity date in May 2029, with two one-year extension options subject to lender approval.

Borrowings under the Corporate Facility bear interest, subject to MSC Income's election, at a rate equal to (i) SOFR plus 2.05% or (ii) the base rate plus 1.05%. The base rate is defined as the higher of (a) the Prime rate, (b) the federal funds rate plus 0.5% or (c) SOFR plus 1.0%. Additionally, MSC Income pays an unused commitment fee of 0.25% on the unused lender commitments if 50% or more of the lender commitments are being used and an unused commitment fee of 0.375% on the unused lender commitments if less than 50% of the lender commitments are being used.

(2)Not annualized.

(3)Unless otherwise noted, operating expenses include interest, base management fees, incentive fees and general and administrative expenses.

(4)For the three months ended March 31, 2026, total investment return is based on the purchase of stock at the current market price on January 1, 2026 and a sale at the current market price on March 31, 2026 and assumes reinvestment of dividends at prices obtained by MSC Income's DRIP during the period. For the three months ended March 31, 2025, total investment return is based on the purchase of stock in the MSC Income Offering at the public offering price of $15.53 and a sale at the market price on March 31, 2025 and assumes reinvestment of dividends at prices obtained by MSC Income's DRIP during the period.

**NOTE F — DIVIDENDS, DISTRIBUTIONS AND TAXABLE INCOME**

MSC Income currently pays regular dividends to its stockholders and periodically pays supplemental dividends to its stockholders. Future dividends, if any, will be determined by its Board of Directors on a quarterly basis.

MSIF has elected to be treated for U.S. federal income tax purposes as a RIC. MSIF's taxable income includes the taxable income generated by MSIF and certain of its subsidiaries, including the Structured Subsidiaries, which are treated as disregarded entities for tax purposes. As a RIC, MSIF generally will not pay corporate-level U.S. federal income taxes on any net ordinary taxable income or capital gains that MSIF distributes to its stockholders. MSIF must generally distribute at least 90% of its "investment company taxable income" (which is generally its net ordinary taxable income and realized net short-term capital gains in excess of realized net long-term capital losses) and 90% of its tax-exempt income to maintain its RIC status (pass-through tax treatment for amounts distributed). As part of maintaining RIC status, undistributed taxable income (subject to a 4% non-deductible U.S. federal excise tax) pertaining to a given fiscal year may be distributed up to twelve months subsequent to the end of that fiscal year, provided such dividends are declared on or prior to the later of (i) filing of the U.S. federal income tax return for the applicable fiscal year or (ii) the fifteenth day of the ninth month following the close of the year in which such taxable income was generated.

The determination of the tax attributes for MSC Income's distributions is made annually, based upon its taxable income for the full year and distributions paid for the full year. Therefore, a determination made on an interim basis may not be representative of the actual tax attributes of distributions for a full year. Ordinary dividend distributions from a RIC do not qualify for the 20% maximum tax rate (plus a 3.8% Medicare surtax, if applicable) on dividend income from domestic corporations and qualified foreign corporations, except to the extent that the RIC received the income in the form of qualifying dividends from domestic corporations and qualified foreign corporations. The tax attributes for distributions will generally include both ordinary income and qualified dividends, but may also include either one or both of capital gains and return of capital.

________________

(1)MSIF's taxable income for each period is an estimate and will not be finally determined until MSIF files its tax return for each year. Therefore, the final taxable income, and the taxable income earned in each period and carried forward for distribution in the following period, may be different than this estimate.

The Taxable Subsidiaries primarily hold certain equity investments for MSC Income. The Taxable Subsidiaries permit MSC Income to hold equity investments in portfolio companies which are "pass-through" entities for tax purposes and to continue to comply with the "source-of-income" requirements contained in the RIC tax provisions of the Code. The Taxable Subsidiaries are consolidated with MSIF for U.S. GAAP financial reporting purposes, and the portfolio investments held by the Taxable Subsidiaries are included in MSC Income's consolidated financial statements as portfolio investments and recorded at fair value. The Taxable Subsidiaries are not consolidated with MSIF for income tax purposes and may generate income tax expense, or benefit, and tax assets and liabilities, as a result of their ownership of certain portfolio investments. The taxable income, or loss, of the Taxable Subsidiaries may differ from their book income, or loss, due to temporary book and tax timing differences and permanent differences. The Taxable Subsidiaries are each taxed at corporate income tax rates based on their taxable income. The income tax expense, or benefit, if any, and the related tax assets and liabilities, of the Taxable Subsidiaries are reflected in MSC Income's consolidated financial statements.

The income tax provision for MSC Income is generally composed of (i) deferred tax expense (benefit), which is primarily the result of the net activity relating to the portfolio investments held in the Taxable Subsidiaries, including changes in loss carryforwards, changes in net unrealized appreciation or depreciation and other temporary book-tax differences, and (ii) current tax expense, which is primarily the result of current U.S. federal income and state taxes relating to net currently taxable activity relating to the portfolio investments held in the Taxable Subsidiaries and excise taxes on MSC Income's estimated undistributed taxable income. The income tax expense, or benefit, and the related tax assets and liabilities generated by the Taxable Subsidiaries, if any, are reflected in MSC Income's Consolidated Statements of Operations. MSC Income's provision for income taxes was comprised of the following for the three months ended March 31, 2026 and 2025:

The net deferred tax liability as of March 31, 2026 and December 31, 2025 was $5.8 million and $5.0 million, respectively, with the change primarily related to changes in net unrealized appreciation or depreciation, changes in loss carryforwards and other temporary book-tax differences relating to portfolio investments held by the Taxable Subsidiaries. As of March 31, 2026, for U.S. federal income tax purposes, the Taxable Subsidiaries had a net operating loss carryforward, which is not subject to expiration and will carryforward indefinitely until utilized. The Taxable Subsidiaries have net capital loss carryforwards from prior years which, if unused, will expire in various taxable years 2029 through 2031. Additionally, the Taxable Subsidiaries have interest expense limitation carryforwards which have an indefinite carryforward period. In addition, as of March 31, 2026, for U.S. federal income tax purposes, MSIF had net capital loss carryforwards totaling $5.1 million available to offset future capital gains at the RIC level in any taxable year, to the extent available and permitted by U.S. federal income tax law, which are not subject to expiration as long as MSIF maintains its RIC status.

**NOTE G — SHARE REPURCHASES**

Following the MSC Income Listing, the Fund entered into a share repurchase plan (the "10b5-1 Repurchase Plan") to repurchase up to $65.0 million in the aggregate of shares of the Fund's common stock in the open market for a twelve-month period beginning in March 2025, at times when the market price per share of the Fund's common stock traded below the most recently reported NAV per share of the Fund's common stock by certain pre-determined levels (including any updates, corrections or adjustments publicly announced by the Fund to any previously announced NAV per share). The repurchases of shares of the Fund's common stock pursuant to the 10b5-1 Repurchase Plan were intended to satisfy the conditions of Rule 10b5-1 and Rule 10b-18 under the Exchange Act and were otherwise subject to applicable law, including Regulation M, which may prohibit purchases under certain circumstances. The 10b5-1 Repurchase Plan expired in March 2026 in accordance with its terms.

Following the MSC Income Listing, Main Street also entered into a share purchase plan (the "Main Street Share Purchase Plan") to purchase up to $20.0 million in the aggregate of shares of the Fund's common stock in the open market for a twelve-month period beginning in March 2025, with terms and conditions substantially similar to the Fund's 10b5-1 Repurchase Plan for shares of the Fund's common stock, and daily purchases under the two plans were split pro rata (or as close thereto as reasonably possible) between the Fund and Main Street based on the respective plan sizes. The Main Street Share Purchase Plan expired in March 2026 in accordance with its terms.

A summary of the shares repurchased by the Fund under the 10b5-1 Repurchase Plan during the three months ended March 31, 2026 is as follows:

(1)Includes broker commissions.

(2)The 10b5-1 Repurchase Plan expired on March 31, 2026; upon expiration, $37.4 million of the total $65 million amount authorized to be repurchased under the 10b5-1 Repurchase Plan expired without being utilized.

**NOTE H — DIVIDEND REINVESTMENT PLAN**

The Fund's dividend reinvestment plan (as amended, the "DRIP") provides for the reinvestment of dividends on behalf of the Fund's registered stockholders who hold their shares with the Fund's transfer agent and registrar, or certain brokerage firms that have elected to participate in the DRIP, unless a stockholder has elected to receive dividends in cash. As a result, if the Fund declares a cash dividend, its registered stockholders (or stockholders holding shares through participating brokerage firms) who have not properly "opted out" of the DRIP will have their cash dividend automatically reinvested into additional shares of the Fund's common stock. The share requirements of the DRIP may be satisfied through the issuance of new shares of common stock, or through open market purchases of common stock by the DRIP plan administrator. Newly issued shares will be valued based upon the final closing price of the Fund's common stock reported on the NYSE on the trading day immediately preceding the dividend payment date for each dividend. Shares purchased in the open market to satisfy the DRIP requirements will be valued based upon the average price of the applicable shares purchased by the DRIP plan administrator, before any associated brokerage or other costs. The DRIP is administered by the Fund's transfer agent.

**MSC INCOME FUND, INC.**

**Notes to the Consolidated Financial Statements (Continued)**

**(Unaudited)**

(1)This table excludes a commitment related to one additional Other Portfolio investment for which the investment period has expired and the remaining commitment may only be drawn to pay fund expenses or for follow-on investments in existing portfolio companies. The Fund does not expect any material future capital to be called on its commitment to this investment to pay fund expenses, and based on representations from the fund manager, the Fund does not expect any further capital will be called on its commitment for follow-on investments. As a result, the Fund has excluded this commitment from this table.

MSC Income will fund its unfunded commitments from the same sources it uses to fund its investment commitments that are funded at the time they are made (which are typically through existing cash and cash equivalents and borrowings under the Credit Facilities). MSC Income follows a process to manage its liquidity and ensure that it has available capital to fund its unfunded commitments as necessary. MSC Income had no unrealized appreciation or depreciation on the outstanding unfunded commitments as of March 31, 2026.

MSC Income may, from time to time, be involved in litigation arising out of its operations in the normal course of business or otherwise. Furthermore, third parties may seek to impose liability on MSC Income in connection with the activities of its portfolio companies. While the outcome of any current legal proceedings cannot at this time be predicted with certainty, MSC Income does not expect any current matters will materially affect its financial condition or results of operations; however, there can be no assurance whether any pending or future legal proceedings will have a material adverse effect on MSC Income's financial condition or results of operations in any future reporting period.

 **NOTE J — RELATED PARTY TRANSACTIONS**

**1. Advisory Agreements and Conditional Expense Reimbursement Waivers**

On October 30, 2020, MSC Income entered into the Prior Investment Advisory Agreement with the Adviser. On January 29, 2025, in connection with the MSC Income Listing, MSC Income entered into the Advisory Agreement with the Adviser. The Advisory Agreement was approved by the affirmative vote of the holders of a majority of MSC Income's outstanding voting securities, as defined in the 1940 Act, at the 2024 Special Meeting, and the Advisory Agreement became effective upon the MSC Income Listing. The Advisory Agreement is effective for an initial two-year term commencing upon the date of the MSC Income Listing on January 29, 2025.

*Prior Investment Advisory Agreement*

Pursuant to the Prior Investment Advisory Agreement, MSC Income paid the Adviser a base management fee and incentive fees as compensation for the services described above. The base management fee was calculated at an annual rate of 1.75% of MSC Income's average gross assets. The term "gross assets" meant total assets of MSC Income as disclosed on MSC Income's Consolidated Balance Sheets. "Average gross assets" were calculated based on MSC Income's gross assets at the end of the two most recently completed calendar quarters. The base management fee was payable quarterly in arrears. The base management fee was expensed as incurred.

The incentive fee under the Prior Investment Advisory Agreement consisted of two parts. The first part, referred to as the subordinated incentive fee on income, was calculated and payable quarterly in arrears based on Pre-Incentive Fee Net Investment Income (as defined below) for the immediately preceding quarter. The subordinated incentive fee on income was equal to 20.0% of MSC Income's Pre-Incentive Fee Net Investment Income for the immediately preceding quarter, expressed as a quarterly rate of return on adjusted capital at the beginning of the most recently completed calendar quarter, exceeding 1.875% (or 7.5% annualized), subject to a "catch up" feature (as described below).

**MSC INCOME FUND, INC.**

**Notes to the Consolidated Financial Statements (Continued)**

**(Unaudited)**

For this purpose, "Pre-Incentive Fee Net Investment Income" meant interest income, dividend income and any other income (including any other fees such as commitment, origination, structuring, diligence and consulting fees or other fees that MSC Income receives from portfolio companies) accrued during the calendar quarter, minus MSC Income's operating expenses for the quarter (including the management fee, expenses payable under any proposed administration agreement and any interest expense and dividends paid on any issued and outstanding preferred stock, but excluding taxes and the incentive fee). Pre-Incentive Fee Net Investment Income included, in the case of investments with a deferred interest feature (such as original issue discount debt instruments and PIK interest and zero coupon securities), accrued income that MSC Income had not yet received in cash. Pre-Incentive Fee Net Investment Income did not include any realized capital gains, realized capital losses or unrealized capital appreciation or depreciation. For purposes of this fee, adjusted capital meant cumulative gross proceeds generated from sales of MSC Income's common stock (including proceeds from MSC Income's DRIP) reduced for non-liquidating distributions, other than distributions of profits, paid to MSC Income's stockholders and amounts paid for share repurchases pursuant to MSC Income's share repurchase program. The subordinated incentive fee on income was expensed in the quarter in which it was incurred.

The calculation of the subordinated incentive fee on income for each quarter was as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• No subordinated incentive fee on income was payable to the Adviser in any calendar quarter in which MSC Income's Pre-Incentive Fee Net Investment Income did not exceed the hurdle rate of 1.875% (or 7.5% annualized) on adjusted capital;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 100% of MSC Income's Pre-Incentive Fee Net Investment Income, if any, that exceeded the hurdle rate but was less than or equal to 2.34375% in any calendar quarter (9.375% annualized) was payable to the Adviser. This portion of the subordinated incentive fee on income was referred to as the "catch up" and was intended to provide the Adviser with an incentive fee of 20.0% on all of MSC Income's Pre-Incentive Fee Net Investment Income as if the hurdle rate did not apply when the Pre-Incentive Fee Net Investment Income exceeded 2.34375% (9.375% annualized) in any calendar quarter; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• For any quarter in which MSC Income's Pre-Incentive Fee Net Investment Income exceeded 2.34375% (9.375% annualized), the subordinated incentive fee on income equaled 20.0% of the amount of MSC Income's Pre-Incentive Fee Net Investment Income, as the hurdle rate and catch-up had been achieved.

The second part of the incentive fee, referred to as the incentive fee on capital gains, was an incentive fee on realized capital gains earned from the portfolio of MSC Income and was determined and payable in arrears as of the end of each calendar year (or upon termination of the Prior Investment Advisory Agreement). This fee equaled 20.0% of MSC Income's incentive fee capital gains, which equaled MSC Income's realized capital gains on a cumulative basis from inception, calculated as of the end of each calendar year, computed net of all realized capital losses and unrealized capital depreciation on a cumulative basis, less the aggregate amount of any previously paid capital gain incentive fees. At the end of each reporting period, MSC Income estimated the incentive fee on capital gains and accrued the fee based on a hypothetical liquidation of its portfolio. Therefore, the accrual included both net realized gains and net unrealized gains (the net unrealized difference between the fair value and the par value of its portfolio), if any. The incentive fee accrued pertaining to the unrealized gain was neither earned nor payable to the Adviser until such time it was realized.

Pursuant to the Prior Investment Advisory Agreement, MSC Income was required to pay or reimburse the Adviser for administrative services expenses, which included all costs and expenses related to MSC Income's day-to-day administration and management not related to advisory services, whether such administrative services were performed by a third-party service provider or the Adviser or its affiliates (to the extent performed by the Adviser or its affiliates, the "Internal Administrative Services"). Internal Administrative Services included, but were not limited to, the cost of an Adviser's personnel performing accounting and compliance functions and other administrative services on behalf of MSC Income.

On January 1, 2022, the Adviser assumed responsibility of certain administrative services that were previously provided for MSC Income by a third-party sub-administrator. After December 31, 2021, the Adviser continued to waive reimbursement of all Internal Administrative Services expenses, except for the cost of the services previously provided by the sub-administrator.

*Advisory Agreement (post-MSC Income Listing)*

Effective on the date of the MSC Income Listing and pursuant to the Advisory Agreement, MSC Income pays the Adviser a base management fee and incentive fees as compensation for investment management services under the Advisory Agreement. The base management fee is calculated at an annual rate of 1.5% of the Fund's average total assets (including cash and cash equivalents), payable quarterly in arrears, and is calculated based on the average value of the Fund's total assets (including cash and cash equivalents) at the end of the two most recently completed calendar quarters. The determination of total assets reflects changes in the fair value of portfolio investments reflecting both unrealized appreciation and unrealized depreciation. All or any part of base management fee not taken as to any quarter is deferred without interest and may be taken in such other quarter as the Adviser shall determine, unless the Adviser permanently waives in writing receipt of such base management fee, in which event the Fund shall forever be relieved of the obligation to pay such base management fee for such quarter. The base management fee for any partial quarter is appropriately pro-rated.

Under the Advisory Agreement, the base management fee will be reduced to an annual rate of (i) 1.25% of the average value of the Fund's total assets (including cash and cash equivalents) commencing with the first full calendar quarter following the date on which the aggregate fair value of the Fund's investments in its LMM portfolio companies falls below 20% of the Fund's total investment portfolio at fair value and (ii) 1.00% of the average value of the Fund's total assets (including cash and cash equivalents) commencing with the first full calendar quarter following the date on which the aggregate fair value of the Fund's investments in its LMM portfolio companies falls below 7.5% of the Fund's total Investment Portfolio at fair value.

The incentive fee under Advisory Agreement consists of two parts: (1) a subordinated incentive fee on income and (2) an incentive fee on capital gains. The incentive fee under the Advisory Agreement for any partial quarter is appropriately pro-rated.

The first part of the incentive fee under the Advisory Agreement, referred to as the subordinated incentive fee on income, is calculated and payable quarterly in arrears based on the Fund's pre-incentive fee net investment income for the immediately preceding quarter. The payment of the subordinated incentive fee on income is subject to pre-incentive fee net investment income for the previous quarter, expressed as a quarterly rate of return on net assets of the Fund at the beginning of the most recently completed calendar quarter, exceeding 1.5% (6.0% annualized), subject to a "catch up" feature (as described below). For this purpose, pre-incentive fee net investment income means interest income, dividend income and any other income (including any other fees, such as commitment, origination, structuring, diligence and consulting fees or other fees that the Fund receives from portfolio companies) accrued during the calendar quarter, minus the Fund's operating expenses for the quarter (including the base management fee, administrative services expenses, the expenses payable under any other administration or similar agreement and any interest expense and dividends paid on any issued and outstanding preferred stock and any income tax expense on the Fund's net investment income and any excise tax, but excluding any income tax expense or benefit on the Fund's realized capital gains, realized capital losses or unrealized capital appreciation or depreciation and the incentive fee). Pre-incentive fee net investment income includes, in the case of investments with a deferred interest feature (such as original issue discount debt instruments with payment-in-kind interest and zero coupon securities), accrued income that the Fund has not yet received in cash. Pre-incentive fee net investment income does not include any realized capital gains, realized capital losses or unrealized capital appreciation or depreciation, or any income tax expense or benefit related to such items. The calculation of the subordinated incentive fee on income for each quarter is as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.No subordinated incentive fee on income is payable to the Adviser in any calendar quarter in which the Fund's pre-incentive fee net investment income does not exceed the hurdle rate of 1.5% (or 6.0% annualized);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.50% of the Fund's pre-incentive fee net investment income, if any, that exceeds the hurdle rate but is less than or equal to 2.307692% in any calendar quarter (9.230769% annualized) is payable to the Adviser. This portion of the subordinated incentive fee on income is referred to as the "catch up" and is intended to provide the Adviser with an incentive fee of 17.5% on all of the Fund's pre-incentive fee net investment income as if the hurdle rate did not apply when the pre-incentive fee net investment income exceeds 2.307692% (9.230769% annualized) in any calendar quarter; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.For any quarter in which the Fund's pre-incentive fee net investment income exceeds 2.307692% (9.230769% annualized), the subordinated incentive fee on income equals 17.5% of the amount of the Fund's pre-incentive fee net investment income, as the hurdle rate and catch-up have been achieved.

The second part of the incentive fee under the Advisory Agreement, referred to as the incentive fee on capital gains, is an incentive fee on realized capital gains earned on liquidated investments from the Fund's Investment Portfolio, net of any income tax expense associated with such realized capital gains, and is determined and payable in arrears as of the end of each calendar year (or upon termination of the Advisory Agreement). This fee equals:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (a) 17.5% of the Fund's incentive fee capital gains, which equals the Fund's realized capital gains (net of any related income tax expense) on a cumulative basis from the date of the MSC Income Listing, calculated as of the end of each calendar year thereafter (or upon termination of the Advisory Agreement), computed net of (1) all realized capital losses on a cumulative basis (net of any related income tax benefit) from the date of the MSC Income Listing, and (2) unrealized capital depreciation (net of any related income tax benefit) on a cumulative basis from the date of the MSC Income Listing, less

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) the aggregate amount of any previously paid capital gain incentive fees from the date of the MSC Income Listing. For purposes of calculating each component of the Fund's incentive fee capital gains under the Advisory Agreement, (1) the cost basis for any investment held by the Fund as of the date of the MSC Income Listing is deemed to be the fair value for such investment as of the most recent quarter end immediately prior to the date of the MSC Income Listing and, with respect to any investment acquired by the Fund subsequent to the date of the MSC Income Listing, the cost basis equals the cost basis of such investment as reflected in the Fund's financial statements and (2) the income tax expense or benefit associated with all investments is measured from the most recent quarter end immediately prior to the date of the MSC Income Listing through the date of any such calculation.

The Fund accrues the incentive fee on capital gains on a quarterly basis by following a formula consistent with the cash payment formula required under the Advisory Agreement above. However, in addition to the Fund's net realized capital gains and unrealized losses (or fair value depreciation) (in part (a) of the formula above), the Fund's unrealized capital gains (or fair value appreciation) (net of any related income tax expense) on a cumulative basis from the date of the MSC Income Listing are also included in the calculation. If the calculation results in an increase in the accrual compared to the previous quarter, the Fund records an increase to the capital gains incentive fee accrual. If the calculation results in a decrease to the estimated incentive fee on capital gains when compared to the previous quarter, the accrual for the incentive fee on capital gains is reduced to the extent of such decrease. For the first quarter of 2026, such calculation resulted in a reduction to the capital gains incentive fee accrual from $2.8 million as of December 31, 2025 to $2.1 million as of March 31, 2026. As such, the Fund reduced the accrual on the capital gains incentive fee by $0.6 million. However, as of March 31, 2026 no capital gains incentive fees were currently contractually payable.

A summary of MSC Income's base management fee, subordinated incentive fee on income, waiver of the subordinated incentive fee on income and incentive fee on capital gains for the three months ended March 31, 2026 and 2025 is as follows:

**(Unaudited)**

Under the Advisory Agreement, the waivers under the Prior Investment Advisory Agreement of Internal Administrative Services expenses, except for the cost of the services previously provided by the former sub-administrator, were memorialized as a quarterly cap on the Fund's obligation to reimburse the Adviser for "Internal Administrative Expenses." MSC Income is not required to reimburse the Adviser for Internal Administrative Expenses in an amount that exceeds on a quarterly basis the product obtained by multiplying (x) the value of MSC Income's total assets at the end of each calendar quarter by (y) the applicable "Annual Basis Point Rate" set forth in the below table:

---

|:---|:---|
| **Total Assets** | **Annual Basis Point Rate** |
| $0 - $500 million | 6.000 |
| Over $500 million - $1.25 billion | 5.125 |
| Greater than $1.25 billion | 4.500 |

**2. Indemnification**

The Prior Investment Advisory Agreement and the Advisory Agreement provide that the Adviser, any sub-adviser and their respective officers, directors, managers, partners, shareholders, members (and their shareholders or members, including the owners of their shareholders or members), agents, employees, controlling persons and any other person or entity affiliated with or acting on behalf of the Adviser or any sub-adviser, as applicable (each an "Indemnified Party" and, collectively, the "Indemnified Parties") will not be liable to MSC Income for any action taken or omitted to be taken by the Adviser or any sub-adviser in connection with the performance of any of their duties or obligations as an investment adviser of the Fund (except to the extent specified in Section 36(b) of the 1940 Act concerning loss resulting from a breach of fiduciary duty (as the same is finally determined by judicial proceedings) with respect to the receipt of compensation for services), and that MSC Income will indemnify, defend and protect Indemnified Parties and hold them harmless from and against all losses, damages, liabilities, costs and expenses (including reasonable attorneys' fees and amounts reasonably paid in settlement) incurred by the Indemnified Parties in connection with the performance of their duties as an investment adviser of the Fund, to the extent such losses, damages, liabilities, costs and expenses are not fully reimbursed by insurance, and to the extent that such indemnification would not be inconsistent with the Maryland General Corporation Law, the 1940 Act, the Fund's charter and other applicable law if, among other things, (i) the Indemnified Party has determined, in good faith, that the course of conduct which caused the loss or liability was in the best interests of the Fund, (ii) the Indemnified Party was acting on behalf of or performing services for the Fund, (iii) such liability or loss was not the result of negligence, willful misfeasance, bad faith, or misconduct by the Indemnified Party and (iv) such indemnification or agreement to hold harmless is recoverable only out of the Fund's net assets and not from stockholders.

**3. Co-Investment**

In the ordinary course of business, MSC Income enters into transactions with other parties that may be considered related party transactions. MSC Income has implemented certain policies and procedures, both written and unwritten, to ensure that it does not engage in any prohibited transactions with any persons affiliated with MSC Income. If such affiliations are found to exist, MSC Income seeks the Board of Directors and/or appropriate Board of Directors committee review and approval for such transactions and otherwise comply with, or seek, orders for exemptive relief from the SEC, as appropriate.

**(Unaudited)**

MSC Income has received an exemptive order from the SEC permitting co-investments among MSC Income, Main Street and other advisory clients of the Adviser in certain negotiated transactions where co-investing would otherwise be prohibited under the 1940 Act. MSC Income has made co-investments, and in the future intends to continue to make co-investments with Main Street and other advisory clients of the Adviser, in accordance with the conditions of the order. Because the Adviser is wholly-owned by Main Street and is not managing MSC Income's investment activities as its sole activity, this may provide the Adviser an incentive to allocate opportunities to other participating advisory clients instead of MSC Income. However, both MSC Income and the Adviser have adopted policies and procedures pursuant to the order to manage this conflict and ensure that investment opportunities are allocated in a manner that is fair and equitable considering each investor's interests, including oversight of the co-investment program by the independent members of MSC Income's and Main Street's boards of directors and their required approval of certain co-investment transactions thereunder. Additional information regarding the operation of the co-investment program is set forth in the order granting exemptive relief, which may be reviewed on the SEC's website at www.sec.gov. In addition to the co-investment program described above, MSC Income also co-invests in certain investment transactions where price is the only negotiated point by MSC Income and its affiliates.

**4. Other Related Party Transactions**

A summary of Main Street's purchases of shares of MSC Income's common stock, each of which was purchased pursuant to the Main Street Share Purchase Plan, during the three months ended March 31, 2026 is as follows:

(1)Includes broker commissions.

(2)The Main Street Share Purchase Plan expired on March 31, 2026; upon expiration, $11.5 million of the total $20 million amount authorized to be purchased under the Main Street Share Purchase Plan expired without being utilized.

On January 20, 2025, in connection with Main Street's potential acquisition in excess of 3% of the Fund's outstanding common stock as a result of any purchases of shares of the Fund's common stock pursuant to the Main Street Share Purchase Plan or otherwise, the Fund entered into a Fund of Funds Investment Agreement with Main Street (the "Main Street Fund of Funds Agreement"). The Main Street Fund of Funds Agreement provides for the acquisition of shares of the Fund's common stock by Main Street, and the Fund's sale of such shares to Main Street, in a manner consistent with the requirements of Rule 12d1-4 under the 1940 Act.

As of March 31, 2026, Main Street owned 2,025,220 shares of MSC Income's common stock. Each issuance and sale of MSC Income shares by MSC Income to Main Street, either individually or through approval of the Main Street Share Purchase Plan, was unanimously approved by the Board of Directors, including each director who is not an "interested person," as such term is defined in Section 2(a)(19) of the 1940 Act, of the Fund or the Adviser. In addition, certain of Main Street's officers and employees own shares of MSC Income and therefore have direct pecuniary interests in MSC Income.

On February 26, 2026, MSC Income and Main Street entered into the Main Street Facility. The Main Street Facility was unanimously approved by the Board of Directors, including each director who is not an "interested person," as such term is defined in Section 2(a)(19) of the 1940 Act, of the Fund or the Adviser. For more information on the Main Street Facility, including key terms and financial covenants, refer to *Note D — Debt*.

The Fund's management has evaluated subsequent events through the date of issuance of the consolidated financial statements, and identified the following to report:

In May 2026, the Board of Directors approved a change to its regular dividend payment frequency from quarterly to monthly beginning in July 2026. Additionally, MSC Income declared regular monthly dividends of $0.11 per share for each month of July, August and September 2026, or total regular monthly dividends of $0.33 per share for the third quarter of 2026, and a supplemental dividend of $0.03 per share, payable in September 2026, resulting in total dividends declared for the third quarter of 2026 of $0.36 per share.

**ORGANIZATION**

MSC Income Fund, Inc. ("MSIF" or, together with its consolidated subsidiaries, "MSC Income" or the "Fund") is a principal investment firm primarily focused on providing debt capital to private ("Private Loan") companies owned by or in the process of being acquired by a private equity fund (its "Private Loan investment strategy"). MSC Income's portfolio investments are typically made to support leveraged buyouts, recapitalizations, growth financings, refinancings and acquisitions of companies that operate in diverse industry sectors. The Fund seeks to partner with private equity fund sponsors in its Private Loan investment strategy and primarily invests in secured debt investments of Private Loan companies generally headquartered in the U.S.

MSC Income also maintains a portfolio of customized long-term debt and equity investments in lower middle market ("LMM") companies (its "LMM investment portfolio"), and through those investments the Fund has partnered with entrepreneurs, business owners and management teams in co-investments with Main Street Capital Corporation ("Main Street"), a New York Stock Exchange ("NYSE") listed business development company ("BDC"), utilizing the customized "one-stop" debt and equity financing solutions provided in Main Street's LMM investment strategy (the "LMM investment strategy"). Through the LMM investment strategy, MSC Income primarily invested in secured debt investments, equity investments, warrants and other securities of LMM companies typically based in the U.S. Effective upon the MSC Income Listing (as defined below) on January 29, 2025, MSC Income changed its investment strategy for investments in new portfolio companies to be solely focused on its Private Loan investment strategy, rather than its historical focus primarily on the Private Loan investment strategy and secondarily on the LMM investment strategy (as further discussed below).

------

<u>[Table of contents](#i67b2a34b0c294631ad7f17e74adf23d3_7)</u>

MSC Income also maintains a legacy portfolio of investments in larger middle market ("Middle Market") companies (its "Middle Market investment portfolio") and a limited portfolio of other portfolio ("Other Portfolio") investments. MSC Income's Middle Market investments are generally debt investments in companies owned by a private equity fund that were originally issued through a syndication financing process. MSC Income has generally stopped making new Middle Market investments and expects the size of its Middle Market investment portfolio to continue to decline in future periods as its existing Middle Market investments are repaid or sold. MSC Income's Other Portfolio investments primarily consist of investments that are not consistent with the typical profiles for its Private Loan, LMM or Middle Market portfolio investments, including investments in unaffiliated investment companies and private funds managed by third parties. Similar to its Middle Market investments, MSC Income has generally stopped making new Other Portfolio investments and expects the size of its Other Portfolio to continue to decline in future periods as its existing Other Portfolio investments are repaid or sold.

The "Investment Portfolio," as used herein, refers to all of MSC Income's investments in Private Loan portfolio companies, investments in LMM portfolio companies, investments in Middle Market portfolio companies and Other Portfolio investments.

MSIF was formed in November 2011 to operate as an externally managed BDC under the Investment Company Act of 1940, as amended (the "1940 Act"). MSIF has elected to be treated for U.S. federal income tax purposes as a regulated investment company ("RIC") under Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code"). As a result, MSIF generally does not pay corporate-level U.S. federal income taxes on any net ordinary taxable income or capital gains that it distributes to its stockholders.

On October 28, 2020, MSC Income's stockholders approved the appointment of MSC Adviser I, LLC (the "Adviser"), which is wholly-owned by Main Street, as MSC Income's investment adviser and administrator under an Investment Advisory and Administrative Services Agreement dated October 30, 2020 (the "Prior Investment Advisory Agreement").

On January 29, 2025, MSC Income's shares of common stock were listed on the NYSE under the ticker symbol "MSIF" (the "MSC Income Listing").

On January 29, 2025, in connection with the MSC Income Listing, MSC Income entered into an Amended and Restated Investment Advisory and Administrative Services Agreement (the "Advisory Agreement") with the Adviser. The Advisory Agreement was approved by the affirmative vote of the holders of a majority of MSC Income's outstanding voting securities, as defined in the 1940 Act, at a special meeting of MSC Income's stockholders held on December 11, 2024, and the Advisory Agreement became effective upon the MSC Income Listing. In such role, the Adviser has the responsibility to manage the business of MSC Income, including the responsibility to identify, evaluate, negotiate and structure prospective investments, make investment and portfolio management decisions, monitor its Investment Portfolio and provide ongoing administrative services.

On January 29, 2025, in connection with the MSC Income Listing, the Fund amended and restated its Articles of Amendment and Restatement, as amended, by filing new Articles of Amendment and Restatement of the Fund (the "New Articles") with the State Department of Assessments and Taxation of the State of Maryland. The New Articles revised the Fund's charter to, among other things, (i) include a provision that limits the transferability of shares of its common stock outstanding at the time of the MSC Income Listing during the 365-day period following the MSC Income Listing, (ii) reflect an amendment to delete provisions regarding restrictions and requirements applicable to its dividend reinvestment plan, (iii) reflect an amendment to delete provisions prohibiting acquisitions of assets in exchange for shares of its common stock and restricting certain transactions between the Fund and the Adviser and its affiliates and (iv) delete certain provisions required by, and remove references to, the NASAA Guidelines in order to conform certain provisions of the Fund's charter more closely to provisions in the charters of other BDCs whose securities are listed and publicly-traded on a national securities exchange.

On January 30, 2025, in connection with the MSC Income Listing, MSC Income closed a follow-on public offering of 5,500,000 shares of its common stock, at the public offering price of $15.53 per share. In addition, on February 3, 2025, MSC Income issued and sold 825,000 additional shares of its common stock, at the public offering price of $15.53 per share, pursuant to the underwriters' full exercise of their overallotment option (together with the offering and sale of the 5,500,000 shares, the "MSC Income Offering"). Net of underwriting discounts and commissions and offering costs, the Fund received net cash proceeds of $90.5 million in connection with the MSC Income Offering.

MSIF has certain direct and indirect wholly-owned subsidiaries that have elected to be taxable entities (the "Taxable Subsidiaries"). The primary purpose of the Taxable Subsidiaries is to permit MSIF to hold equity investments in portfolio companies which are "pass-through" entities for tax purposes. MSIF also has certain direct and indirect wholly-owned subsidiaries formed for financing purposes (the "Structured Subsidiaries").

Unless otherwise noted or the context otherwise indicates, the terms "MSC Income" and the "Fund" refer to MSIF and its consolidated subsidiaries, which include the Taxable Subsidiaries and the Structured Subsidiaries.

**OVERVIEW OF THE BUSINESS**

MSC Income's principal investment objective is to maximize the Investment Portfolio's total return, primarily by generating current income from debt investments and, to a lesser extent, by generating current income and capital appreciation from equity and equity-related investments, including warrants, convertible securities and other rights to acquire equity securities in a portfolio company. MSC Income seeks to achieve its investment objective primarily through its Private Loan investment strategy and its LMM investment portfolio. MSC Income's Private Loan investment strategy involves investments in companies that generally have annual revenues between $25 million and $500 million and annual earnings before interest, tax, depreciation and amortization expenses ("EBITDA") between $7.5 million and $50 million. MSC Income's LMM investment portfolio consists of investments in companies that generally have annual revenues between $10 million and $150 million and annual EBITDA between $3 million and $20 million. MSC Income's Private Loan and LMM investments generally range in size from $1 million to $30 million.

Private Loan investments primarily consist of debt securities that have primarily been originated directly by the Adviser or, to a lesser extent, through the Adviser's strategic relationships with other investment funds on a collaborative basis through investments that are often referred to in the debt markets as "club deals" because of the small lender group size. In both cases, MSC Income's Private Loan investments are typically made in a company owned by or in the process of being acquired by a private equity fund. The Fund's Private Loan portfolio debt investments are generally secured by a first priority lien on the assets of the portfolio company and typically have a term of between three and seven years from the original investment date. The Fund may also co-invest with Main Street and the private equity fund in the equity securities of its Private Loan portfolio companies.

MSC Income has also historically sought to fill the financing gap for LMM businesses, which, historically, have had limited access to financing from commercial banks and other traditional sources. The underserved nature of the LMM created the opportunity for MSC Income to meet the financing needs of LMM companies while also negotiating favorable transaction terms and equity participation. MSC Income's ability to invest across a company's capital structure, from secured loans to equity securities, allowed it to offer portfolio companies a comprehensive suite of financing options, or a "one-stop" financing solution. MSC Income's LMM portfolio debt investments are generally secured by a first priority lien on the assets of the portfolio company and typically have a term of between five and seven years from the original investment date.

In connection with the MSC Income Listing, the Fund's Board of Directors and the Adviser decided to change its investment strategy with respect to new platform investments to be solely focused on the Fund's Private Loan investment strategy. As a result, the size of the Fund's LMM investment portfolio is expected to decrease over time as its existing LMM investments are repaid or sold in the ordinary course of business. The Fund does, however, plan to continue executing follow-on investments in its existing LMM portfolio companies going forward in accordance with its existing SEC order for co-investment exemptive relief.

MSC Income's Middle Market investments are generally debt investments in companies owned by a private equity fund that were originally issued through a syndication financing process. MSC Income has generally stopped making new Middle Market investments and expects the size of its Middle Market investment portfolio to continue to decline in future periods as existing Middle Market investments are repaid or sold. MSC Income's Middle Market debt investments generally range in size from $1 million to $20 million, are generally secured by a first priority lien on the assets of the portfolio company and typically have an expected duration of between three and seven years from the original investment date.

MSC Income's Other Portfolio investments primarily consist of investments that are not consistent with the typical profiles for its Private Loan, LMM or Middle Market portfolio investments, including investments in unaffiliated investment companies and private funds managed by third parties. In the Fund's Other Portfolio, it may incur indirect fees and expenses in connection with investments managed by third parties. Similar to MSC Income's Middle Market investments, the Fund has generally stopped making new Other Portfolio investments and expects the size of its Other Portfolio to continue to decline in future periods as existing Other Portfolio investments are repaid or sold.

<u>[Table of contents](#i67b2a34b0c294631ad7f17e74adf23d3_7)</u>

Subject to changes in MSC Income's cash and overall liquidity, it may in the future invest in short-term portfolio investments that are atypical of its Private Loan and LMM portfolio investments in that they would be intended to be a short-term deployment of capital. These assets would be expected to be realized in one year or less and would not be expected to be a significant portion of MSC Income's overall Investment Portfolio.

MSC Income's portfolio investments are generally made through MSIF, the Taxable Subsidiaries and the Structured Subsidiaries. MSIF, the Taxable Subsidiaries and the Structured Subsidiaries share the same investment strategies and criteria. An investor's return in MSIF will depend, in part, on the Taxable Subsidiaries' and the Structured Subsidiaries' investment returns as they are wholly-owned subsidiaries of MSIF.

The level of new portfolio investment activity will fluctuate from period to period based upon MSC Income's view of the current economic fundamentals, its ability to identify new investment opportunities that meet its investment criteria, its ability to consummate the identified opportunities and its available liquidity. The level of new investment activity, and associated interest and fee income, will directly impact future investment income. In addition, the level of dividends paid by portfolio companies and the portion of the Fund's portfolio debt investments on non-accrual status will directly impact future investment income. While MSC Income intends to grow its portfolio and its investment income over the long term, growth and operating results may be more limited during depressed economic periods. However, the Fund intends to appropriately manage its cost structure and liquidity position based on applicable economic conditions and investment outlook. The level of realized gains or losses and unrealized appreciation or depreciation on investments will also fluctuate depending upon portfolio activity, economic conditions and the performance of individual portfolio companies. The changes in realized gains and losses and unrealized appreciation or depreciation could have a material impact on the Fund's operating results.

MSC Income has received an exemptive order from the SEC permitting co-investments among it, Main Street and other advisory clients of the Adviser in certain negotiated transactions where co-investing would otherwise be prohibited under the 1940 Act. MSC Income has made co-investments with, and in the future intends to continue to make co-investments with, Main Street and other advisory clients of the Adviser, in accordance with the conditions of the order. Because the Adviser is wholly-owned by Main Street and is not managing MSC Income's investment activities as its sole activity, this may provide the Adviser an incentive to allocate opportunities to Main Street or its other advisory clients instead of MSC Income. However, both MSC Income and the Adviser have adopted policies and procedures pursuant to the order to manage this conflict and ensure that investment opportunities are allocated in a manner that is fair and equitable considering each investor's interests, including oversight of the co-investment program by the independent members of MSC Income's and Main Street's boards of directors and their required approval of certain co-investment transactions thereunder. In addition to the co-investment program described above, MSC Income also co-invests in certain investment transactions where price is the only negotiated point by the Fund and its affiliates.

(b)The weighted-average annual effective yields were computed using the effective interest rates for all debt investments as of March 31, 2026, including amortization of deferred debt origination fees and accretion of original issue discount but excluding fees payable upon repayment of the debt investments and any debt investments on non-accrual status, and are weighted based upon the principal amount of each applicable debt investment as of March 31, 2026. The weighted-average annual effective yield on the Fund's debt portfolio as of March 31, 2026, including debt investments on non-accrual status, was 10.1% for the Private Loan portfolio investments and 11.9% for the LMM portfolio investments. The weighted-average annual effective yield is not reflective of what an investor in shares of MSC Income's common stock will realize on their investment because it does not reflect changes in the market value of MSC Income's stock, MSC Income's utilization of debt capital in its capital structure, MSC Income's expenses or any sales load paid by an investor.

(c)The average EBITDA is calculated using a weighted-average for Private Loan portfolio companies and a simple average for LMM portfolio companies. These calculations exclude certain portfolio companies, including four Private Loan portfolio companies and three LMM portfolio companies, as EBITDA is not a meaningful valuation metric for the Fund's investments in these portfolio companies, and those portfolio companies whose primary purpose is to own real estate and those portfolio companies whose primary operations have ceased and only residual value remains.

(a)As of December 31, 2025, MSC Income had equity ownership in all of its LMM portfolio companies, and the average fully diluted equity ownership in those portfolio companies was 8%.

(b)The weighted-average annual effective yields were computed using the effective interest rates for all debt investments as of December 31, 2025, including amortization of deferred debt origination fees and accretion of original issue discount but excluding fees payable upon repayment of the debt investments and any debt investments on non-accrual status, and are weighted based upon the principal amount of each applicable debt investment as of December 31, 2025. The weighted-average annual effective yield on the Fund's debt portfolio as of December 31, 2025, including debt investments on non-accrual status, was 10.3% for the Private Loan portfolio investments and 11.7% for the LMM portfolio investments. The weighted-average annual effective yield is not reflective of what an investor in shares of MSC Income's common stock will realize on their investment because it does not reflect changes in the market value of MSC Income's stock, MSC Income's utilization of debt capital in its capital structure, MSC Income's expenses or any sales load paid by an investor.

(c)The average EBITDA is calculated using a weighted-average for Private Loan portfolio companies and a simple average for LMM portfolio companies. These calculations exclude certain portfolio companies, including four Private Loan portfolio companies and three LMM portfolio companies, as EBITDA is not a meaningful valuation metric for the Fund's investments in these portfolio companies, and those portfolio companies whose primary purpose is to own real estate and those portfolio companies whose primary operations have ceased and only residual value remains.

For the three months ended March 31, 2026 and 2025, MSC Income achieved an annualized total return on investments of 9.8% and 10.6%, respectively. For the year ended December 31, 2025, MSC Income achieved a total return on investments of 13.9%. Total return on investments equals the total interest, dividend and fee income plus realized and unrealized changes in the fair value of the Investment Portfolio divided by the average quarterly Investment Portfolio balance at cost, in each case for the specified period. MSC Income's total return on investments is not reflective of what an investor in shares of MSC Income's common stock will realize on their investment because it does not reflect changes in the market value of MSC Income's stock, MSC Income's utilization of debt capital in its capital structure, MSC Income's expenses or any sales load paid by an investor.

<u>[Table of contents](#i67b2a34b0c294631ad7f17e74adf23d3_7)</u>

As of March 31, 2026, MSC Income had Middle Market portfolio investments in eight portfolio companies, collectively totaling $23.0 million in fair value and $40.3 million in cost basis, which comprised 1.7% and 3.1% of the Investment Portfolio at fair value and cost, respectively. As of December 31, 2025, MSC Income had Middle Market portfolio investments in eight portfolio companies, collectively totaling $23.3 million in fair value and $39.8 million in cost basis, which comprised 1.7% and 3.2% of the Investment Portfolio at fair value and cost, respectively.

As of March 31, 2026, MSC Income had Other Portfolio investments in seven entities, spread across four investment managers, collectively totaling $15.6 million in fair value and $13.4 million in cost basis, which comprised 1.1% and 1.0% of the Investment Portfolio at fair value and cost, respectively. As of December 31, 2025, MSC Income had Other Portfolio investments in six entities, spread across four investment managers, collectively totaling $15.5 million in fair value and $13.7 million in cost basis, which comprised 1.2% and 1.1% of the Investment Portfolio at fair value and cost, respectively.

**CRITICAL ACCOUNTING POLICIES**

The preparation of financial statements and related disclosures in conformity with generally accepted accounting principles in the United States of America ("U.S. GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and contingent assets and liabilities as of the date of the financial statements, and revenues and expenses during the periods reported. Actual results could materially differ from those estimates. Critical accounting policies are those that require management to make subjective or complex judgments about the effect of matters that are inherently uncertain and may change in subsequent periods. Changes that may be required in the underlying assumptions or estimates in these areas could have a material impact on MSC Income's current and future financial condition and results of operations.

Management has discussed the development and selection of each critical accounting policy and estimate with the Audit Committee of the Board of Directors. MSC Income's critical accounting policies and estimates include the Investment Portfolio Valuation and Revenue Recognition policies described below. MSC Income's significant accounting policies are described in greater detail in *Note B — Summary of Significant Accounting Policies* in the notes to the consolidated financial statements included in *Item 1. Consolidated Financial Statements* of this Quarterly Report on Form 10-Q.

***Investment Portfolio Valuation***

The most significant determination inherent in the preparation of MSC Income's consolidated financial statements is the valuation of the Investment Portfolio and the related amounts of unrealized appreciation and depreciation. The Fund considers this determination to be a critical accounting estimate, given the significant judgments and subjective measurements required. As of both March 31, 2026 and December 31, 2025, the Fund's Investment Portfolio valued at fair value represented 97% of its total assets. MSC Income is required to report its investments at fair value. The Fund follows the provisions of Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 820, *Fair Value Measurements and Disclosures* ("ASC 820"). ASC 820 defines fair value, establishes a framework for measuring fair value, establishes a fair value hierarchy based on the quality of inputs used to measure fair value and enhances disclosure requirements for fair value measurements. ASC 820 requires the Fund to assume that the portfolio investment is to be sold in the principal market to independent market participants, which may be a hypothetical market. Market participants are defined as buyers and sellers in the principal market that are independent, knowledgeable and willing and able to transact. See *Note B.1. — Summary of Significant Accounting Policies — Valuation of the Investment Portfolio* in the notes to the consolidated financial statements included in *Item 1. Consolidated Financial Statements* of this Quarterly Report on Form 10-Q for a detailed discussion of the Valuation Procedures (as defined below).

Due to the inherent uncertainty in the valuation process, MSC Income's determination of fair value for the Investment Portfolio may differ materially from the values that would have been determined had a ready market for the securities existed. In addition, changes in the market environment, portfolio company performance and other events that may occur over the lives of the investments may cause the gains or losses ultimately realized on these investments to be materially different than the valuations currently assigned. MSC Income determines the fair value of each individual investment and records changes in fair value as unrealized appreciation or depreciation.

Rule 2a-5 under the 1940 Act permits a BDC's board of directors to designate its executive officers or investment adviser as a valuation designee to determine the fair value for its investment portfolio, subject to the active oversight of the board. MSC Income's Board of Directors has approved policies and procedures pursuant to Rule 2a-5 (the "Valuation Procedures") and designated the Adviser, led by a group of its executive officers, to serve as the Board of Directors' valuation designee thereunder. MSC Income believes the Investment Portfolio as of March 31, 2026 and December 31, 2025 approximates fair value as of those dates based on the markets in which the Fund operates and other conditions in existence on those reporting dates.

***Revenue Recognition***

*Interest and Dividend Income*

MSC Income records interest and dividend income on the accrual basis to the extent amounts are expected to be collected. Dividend income is recorded as dividends are declared by the portfolio company or at the point an obligation exists for the portfolio company to make a distribution. The Fund evaluates accrued interest and dividend income periodically for collectability. When a loan or debt security becomes 90 days or more past due, and if the Fund otherwise does not expect the debtor to be able to service its debt obligation, it will generally place the loan or debt security on non-accrual status and cease recognizing interest income on that loan or debt security until the borrower has demonstrated the ability and intent to pay contractual amounts due. If a loan or debt security's status significantly improves regarding the debtor's ability to service the debt obligation, or if a loan or debt security is sold or written off, the Fund removes it from non-accrual status. Generally, any interest payments received for investments on non-accrual status reduce the cost basis of the investment and are not recorded as income.

*Fee Income*

MSC Income may periodically provide services, including structuring and advisory services, to portfolio companies or other third parties. For services that are separately identifiable and evidence exists to substantiate fair value, fee income is recognized as earned, which is generally when the investment or other applicable transaction closes. Fees received in connection with debt financing transactions for services that do not meet these criteria are treated as debt origination fees and are generally deferred and accreted into income over the life of the financing.

*Payment-in-Kind ("PIK") Interest and Cumulative Dividends*

MSC Income holds certain debt and preferred equity instruments in its Investment Portfolio that contain PIK interest and cumulative dividend provisions. The PIK interest, computed at the contractual rate specified in each debt agreement, is periodically added to the principal balance of the debt and is recorded as interest income. Thus, the actual collection of this interest may be deferred until the time of debt principal repayment. Cumulative dividends are recorded as dividend income, and any dividends in arrears are added to the balance of the preferred equity investment. The actual collection of these dividends in arrears may be deferred until such time as the preferred equity is redeemed or sold. To maintain RIC tax treatment (see *Note B.8. — Summary of Significant Accounting Policies — Income Taxes* in the notes to the consolidated financial statements included in *Item 1. Consolidated Financial Statements* of this Quarterly Report on Form 10-Q), these non-cash sources of income may need to be paid out to stockholders in the form of distributions, even though MSC Income may not have collected the PIK interest and cumulative dividends in cash. MSC Income stops accruing PIK interest and cumulative dividends and writes off any accrued and uncollected interest and dividends in arrears when it determines that such PIK interest and dividends in arrears are no longer collectible. For the three months ended March 31, 2026 and 2025, (i) 7.3% and 5.8%, respectively, of MSC Income's total investment income was attributable to PIK interest income not paid currently in cash and (ii) 0.8% and 0.2%, respectively, of MSC Income's total investment income was attributable to cumulative dividend income not paid currently in cash.

**INVESTMENT PORTFOLIO COMPOSITION**

A summary of the composition of MSC Income's total combined Private Loan, LMM and Middle Market portfolio investments at cost and fair value by type of investment as a percentage of the total combined Private Loan, LMM and Middle Market portfolio investments as of March 31, 2026 and December 31, 2025 is as follows (this information excludes Other Portfolio investments, which are discussed above):

---

| | | |
|:---|:---|:---|
| **Cost:** | **March 31, 2026** | **December 31, 2025** |
| First lien debt | 85.6% | 85.1% |
| Equity | 13.9 | 14.7 |
| Second lien debt | 0.3 |  |
| Equity warrants | 0.2 | 0.2 |
| Other |  |  |

The Fund's Private Loan, LMM and Middle Market portfolio investments carry a number of risks, including: (1) investing in companies which may have limited operating histories and financial resources; (2) holding investments that generally are not publicly traded and which may be subject to legal and other restrictions on resale; and (3) other risks common to investing in below investment-grade debt and equity investments in the Investment Portfolio. See *Item 1A. Risk Factors* contained in Part II of this Form 10-Q for further information.

**PORTFOLIO ASSET QUALITY**

The Adviser utilizes an internally developed investment rating system to rate the performance of each Private Loan, LMM and Middle Market portfolio company and to monitor the expected level of returns on each of the Private Loan, LMM and Middle Market investments in relation to the expectations for the portfolio company. The investment rating system takes into consideration various factors, including, but not limited to, each investment's expected level of returns, the collectability of the Fund's debt investments and the ability to receive a return of the invested capital in the Fund's equity investments, comparisons to competitors and other industry participants, the portfolio company's future outlook and other factors that are deemed to be significant to the portfolio company.

As of March 31, 2026, investments on non-accrual status were $15.1 million at fair value and $55.0 million at cost and comprised 1.1% and 4.2% of MSC Income's total Investment Portfolio at fair value and cost, respectively. As of December 31, 2025, investments on non-accrual status were $13.7 million at fair value and $49.0 million at cost and comprised 1.0% and 3.9% of MSC Income's total Investment Portfolio at fair value and cost, respectively.

The operating results of the Fund's portfolio companies are impacted by changes in the broader fundamentals of the U.S. economy. In periods during which the U.S. economy contracts, it is likely that the financial results of small to mid-sized companies, like those in which the Fund invests, could experience deterioration or limited growth from current levels, which could ultimately lead to difficulty in meeting their debt service requirements, to an increase in defaults on debt investments or in realized losses on investments and to difficulty in maintaining historical dividend payment rates and unrealized appreciation on the Fund's equity investments. Consequently, the Fund can provide no assurance that the performance of certain portfolio companies will not be negatively impacted by future economic cycles or other conditions, which could also have a negative impact on the Fund's future results.

(a)Pursuant to the Advisory Agreement, the incentive fee on capital gains is determined and payable to the Adviser in arrears, if any, as of the end of each calendar year. This fee equals (a) 17.5% of the Fund's incentive fee capital gain, which is calculated as the Fund's (i) cumulative net realized gains (net of any related net income tax expense), minus (ii) cumulative unrealized depreciation (net of any related income tax benefit, and excluding any unrealized appreciation), minus (b) the aggregate amount of any previously paid capital gains incentive fee, in each case from the MSC Income Listing date through the applicable calendar year ended. In accordance with U.S. GAAP, at the end of each reporting period, the Fund estimates the capital gains incentive fee and adjusts the accrual for the fee based upon a hypothetical liquidation of its investment portfolio at the then current fair value. Therefore, the calculation of the accrual equals (a) the Fund's cumulative change in net fair value, including both (i) the cumulative net realized gain/loss and (ii) the cumulative net unrealized appreciation/depreciation (in both cases, net of any related cumulative net income tax expense or benefit), minus (b) the aggregate amount of any previously paid capital gains incentive fee, in each case from the MSC Income Listing date through the applicable period ended. However, any capital gains incentive fee accrued related to the unrealized appreciation is neither earned nor payable to the Adviser until such time that it is realized, and assuming at the end of a calendar year such incentive fee capital gain exists excluding any cumulative unrealized appreciation (in each case, net of any related net income tax expense or benefits). If the calculation results in an increase in the accrual compared to the previous quarter, the Fund records an increase to the capital gains incentive fee accrual. If the calculation results in a decrease to the estimated incentive fee on capital gains when compared to the previous quarter, the accrual for the incentive fee on capital gains is reduced to the extent of such decrease. For the first quarter of 2026, the Fund reduced the accrual on the capital gains incentive fee by $0.6 million. See *Note J — Related Party Transactions and Arrangements* in the notes to the consolidated financial statements included in Item 1. Consolidated Financial Statements of this Quarterly Report on Form 10-Q.

(b)Adjusted net investment income is net investment income as determined in accordance with U.S. GAAP, excluding the impact of the capital gains incentive fee. MSC Income believes presenting adjusted net investment income and the related per share amounts is useful and appropriate supplemental disclosure for analyzing the Fund's financial performance since the calculation of the capital gains incentive fee is based on realized gains and losses and unrealized fair value appreciation and depreciation, none of which are included in net investment income. However, adjusted net investment income is a non-U.S. GAAP measure and should not be considered as a replacement for net investment income or other earnings measures presented in accordance with U.S. GAAP and should be reviewed only in connection with such U.S. GAAP measures in analyzing MSC Income's financial performance. A reconciliation of net investment income in accordance with U.S. GAAP to adjusted net investment income is detailed in the table above.

(c)Adjusted net investment income before taxes is net investment income as determined in accordance with U.S. GAAP, excluding the impact of any tax expenses included in net investment income and the capital gains incentive fee. MSC Income believes presenting adjusted net investment income before taxes and the related per share amounts is useful and appropriate supplemental disclosure for analyzing the Fund's financial performance since (i) the calculation of the capital gains incentive fee is based on realized gains and losses and unrealized fair value appreciation and depreciation, none of which are included in net investment income and (ii) tax expenses included in net investment income may include (a) excise tax expense, which is not solely attributable to net investment income, and (b) deferred taxes, which are not payable in the current period. However, adjusted net investment income before taxes is a non-U.S. GAAP measure and should not be considered as a replacement for net investment income, net investment income before taxes or other earnings measures presented in accordance with U.S. GAAP and should be reviewed only in connection with such U.S. GAAP measures in analyzing MSC Income's financial performance. A reconciliation of net investment income in accordance with U.S. GAAP to adjusted net investment income before taxes is detailed in the table above.

*Investment Income*

Total investment income for the three months ended March 31, 2026 was $34.1 million, a 3% increase from the $33.2 million for the corresponding period of 2025. A summary of the changes in the comparable period activity is as follows:

---

| | | | | | |
|:---|:---|:---|:---|:---|:---|
| | **Three Months Ended<br>March 31,** | **Three Months Ended<br>March 31,** | **Net Change** | **Net Change** | |

| Dividend income | 3538 | 5142 | (1604) | (31)% | (b) |
| Fee income | 1170 | 661 | 509 | 77% | (c) |
| &nbsp;&nbsp;&nbsp;Total investment income | $34087 | $33227 | $860 | 3% | (d) |

---

_________________

(a)The increase in interest income was principally attributable to higher average levels of income producing Investment Portfolio debt investments, partially offset by a decrease in interest rates, primarily resulting from decreases in benchmark index interest rates on floating rate Investment Portfolio debt investments.

(b)The decrease in dividend income was primarily a result of a $1.5 million decrease in dividend income from the Fund's LMM portfolio companies.

(c)The increase in fee income was primarily due to a $0.3 million increase in fees related to increased investment activity.

(d)The increase in total investment income is after the impact of a net decrease of $0.2 million in certain income considered less consistent or non-recurring, primarily related to decreases of (i) $0.2 million in such dividend income and (ii) $0.2 million in such interest income from accelerated prepayment, repricing and other activity related to certain Investment Portfolio debt investments, partially offset by a $0.2 million increase in such fee income.

*Expenses*

Total expenses, net of expense waivers for the three months ended March 31, 2026 were $16.8 million, a 2% increase from $16.4 million in the corresponding period of 2025. A summary of the changes in the comparable period activity is as follows:

---

| | | | | | |
|:---|:---|:---|:---|:---|:---|
| | **Three Months Ended<br>March 31,** | **Three Months Ended<br>March 31,** | **Net Change** | **Net Change** | |

| General and administrative | 1039 | 1027 | 12 | 1% |  |
| Internal administrative services expenses | 186 | 174 | 12 | 7% |  |
| &nbsp;&nbsp;&nbsp;Total expenses before expense waivers | 17831 | 16439 | 1392 | 8% |  |
| Waiver of incentive fee on income | (985) |  | (985) | NM | (c) |
| &nbsp;&nbsp;&nbsp;Total expenses, net of expense waivers | $16846 | $16439 | $407 | 2% |  |

---

_________________

(a)The increase in interest expense was primarily related to an increase in weighted-average outstanding borrowings used to fund the growth of the Fund's Investment Portfolio, partially offset by decreased weighted-average interest rates on the Credit Facilities (as defined in the *Liquidity and Capital Resources* section below) due to (i) decreases in benchmark floating index interest rates and (ii) a decrease to the applicable interest rate spread resulting from the amendment of the SPV Facility in March 2025 (as defined in the *Liquidity and Capital Resources* section below).

------

<u>[Table of contents](#i67b2a34b0c294631ad7f17e74adf23d3_7)</u>

(b)The increase in base management fees was primarily the result of the Fund's increased average total assets, partially offset by the benefit of the lower base management fee percentage for the full quarter in the first quarter of 2026 compared to the benefit for a partial quarter in the first quarter of 2025 as a result of the Fund's entry into the Advisory Agreement with the Adviser, effective upon the MSC Income Listing.

(c)The increase in incentive fee on income, net of waivers, is the result of an increase in the gross calculated incentive fee on income of $1.1 million, partially offset by a $1.0 million voluntary permanent waiver of incentive fee on income by the Adviser. The increase in the gross calculated incentive fee on income is a result of changes to the incentive fee on income calculation under the Advisory Agreement.

(d)The reduction in the capital gains incentive fee accrual is due to the net fair value depreciation of the Fund's investments in the first quarter of 2026.

*Net Investment Income*

Net investment income for the three months ended March 31, 2026 increased to $16.2 million, or $0.35 per share, compared to $15.7 million, or $0.35 per share, in the corresponding period of 2025. The increase in net investment income was primarily attributable to an increase in total investment income, partially offset by an increase in total expenses, net of waivers, each as discussed above. Net investment income on a per share basis includes the impact of a 3% increase in the weighted-average shares outstanding compared to the three months ended March 31, 2025, primarily due to shares issued through the MSC Income Offering and shares issued through the dividend reinvestment plan, partially offset by shares repurchased by the Fund, in each case since the beginning of the comparable period of the prior year. Net investment income on a per share basis for the three months ended March 31, 2026 includes a $0.01 per share decrease in investment income considered less consistent or non-recurring in nature when compared to prior year.

*Adjusted Net Investment Income*

Adjusted net investment income for the three months ended March 31, 2026 decreased 1% to $15.6 million, or $0.34 per share, compared to $15.7 million, or $0.35 per share, in the corresponding period of 2025. The decrease in adjusted net investment income was primarily due to the same factors discussed above for the change in net investment income, but excluding the impact of the decrease in the capital gains incentive fee accrual. The decrease in adjusted net investment income per share reflects (i) the decrease in adjusted net investment income after the impact of the increase in weighted-average shares outstanding for the three months ended March 31, 2026 and (ii) a $0.01 per share decrease in investment income considered less consistent or non-recurring in nature, in both cases as discussed above.

*Net Realized Loss*

A summary of the primary components of the total net realized loss on investments of $0.2 million for the three months ended March 31, 2026 is as follows:

*Income Taxes*

MSC Income's income taxes include excise tax expense at MSIF and federal and state income and other tax expenses at the Taxable Subsidiaries. MSIF has elected to be treated for U.S. federal income tax purposes as a RIC. MSIF's taxable income includes the taxable income generated by MSIF and certain of its subsidiaries, including the Structured Subsidiaries, which are treated as disregarded entities for tax purposes. As a result of its investment activities and dividend policy and activities, MSIF incurs federal excise tax on its estimated undistributed taxable income. The Taxable Subsidiaries incur federal and state income and other taxes related to net investment income resulting from the Taxable Subsidiaries' investment activities. The excise tax expense decrease for the three months ended March 31, 2026 when compared to the prior year is due to a reduction in the estimated undistributed taxable income at MSIF, which is taxed at a 4% rate. The net investment income related federal and state income and other tax expenses increase for the three months ended March 31, 2026 when compared to the prior year is due to increases in taxable net investment income at the Taxable Subsidiaries.

The Taxable Subsidiaries also incur taxes on realized gains (losses) and unrealized appreciation (depreciation). These taxes will change over time due to changes in the valuations of portfolio investments and realized gains and losses, in each case, on investments owned by the Taxable Subsidiaries.

*Net Increase in Net Assets Resulting from Operations*

The net increase in net assets resulting from operations for the three months ended March 31, 2026 was $13.2 million, or $0.29 per share, compared with $15.9 million, or $0.36 per share, for the three months ended March 31, 2025. The tables above provide a summary of the reasons for the change in net increase in net assets resulting from operations for the three months ended March 31, 2026 as compared to the three months ended March 31, 2025.

***LIQUIDITY AND CAPITAL RESOURCES***

*Cash Flows*

For the three months ended March 31, 2026, MSC Income realized a net decrease in cash and cash equivalents of $5.1 million, which is the net result of $18.4 million of cash used in operating activities and $13.3 million of cash provided by financing activities.

The $18.4 million of cash used in operating activities resulted primarily from cash uses totaling $73.7 million for the funding of new and follow-on portfolio investments, partially offset by (i) cash proceeds totaling $41.6 million from the repayments of debt investments and sales of and return of capital from equity investments, (ii) cash flows generated from operating profits earned totaling $12.9 million, which is net investment income, excluding the non-cash effects of deferred taxes, the accretion of unearned income, PIK interest income, cumulative dividends and the amortization expense for deferred financing costs and (iii) $1.0 million in net cash uses related to changes in other assets and liabilities.

------

<u>[Table of contents](#i67b2a34b0c294631ad7f17e74adf23d3_7)</u>

The $13.3 million of cash provided by financing activities principally consisted of $150.0 million in net cash proceeds from the issuance of the May 2029 Notes (as defined below), partially offset by (i) $103.0 million in net cash repayments on the Credit Facilities, (ii) $16.8 million in cash dividends paid to stockholders, (iii) $16.0 million for the repurchases of common stock and (iv) $0.9 million for the payment of deferred financing costs.

*Share Repurchases*

See *Note G — Share Repurchases* in the notes to the consolidated financial statements included in *Item 1. Consolidated Financial Statements* of this Quarterly Report on Form 10-Q for a description of the 10b5-1 Repurchase Plan and shares repurchased thereunder during the three months ended March 31, 2026.

*Capital Resources*

As of March 31, 2026, MSC Income had $15.6 million in cash and cash equivalents and $194.4 million of unused capacity under the Credit Facilities (as defined below), which the Fund maintains to support investment and operating activities. As of March 31, 2026, the Fund's net asset value ("NAV") totaled $719.5 million, or $15.87 per share.

As of March 31, 2026, MSC Income had $83.0 million outstanding and $162.0 million of undrawn commitments under its floating rate multi-year revolving credit facility (the "Corporate Facility") and, through MSIF Funding, had $267.0 million outstanding and $33.0 million of undrawn commitments under its special purpose vehicle revolving credit facility (the "SPV Facility"), both of which approximated fair value. Availability under the Credit Facilities is subject to certain leverage and borrowing base limitations, covenants, reporting and other requirements customary for similar credit facilities.

On February 26, 2026, Main Street provided MSC Income with a revolving line of credit pursuant to an Unsecured Revolving Promissory Note (as amended, restated or otherwise modified, the "Main Street Facility" and, together with the SPV Facility and the Corporate Facility, the "Credit Facilities"), which currently provides for borrowings up to $30.0 million. Borrowings under the Main Street Facility bear interest at a rate of SOFR plus 4.5%, subject to a 2.0% SOFR floor and mature in December 2029. Available borrowings under the Main Street Facility are subject to a 0.25% non-use fee. The borrowings under the Main Street Facility are unsecured. As of March 31, 2026, there were no borrowings outstanding under the Main Street Facility.

For further information on the Credit Facilities, including key terms and financial covenants, refer to *Note D — Debt* in the notes to the consolidated financial statements included in *Item 1. Consolidated Financial Statements* of this Quarterly Report on Form 10-Q.

In March 2026, the Fund issued $150.0 million in aggregate principal amount of 6.34% Series A Notes due May 2029 (the "May 2029 Notes"). The outstanding aggregate principal amount of the May 2029 Notes was $150.0 million as of March 31, 2026. For more information on the May 2029 Notes, including key terms and financial covenants, refer to *Note D — Debt* in the notes to the consolidated financial statements included in *Item 1. Consolidated Financial Statements* of this Quarterly Report on Form 10-Q.

In October 2021, the Fund issued $77.5 million in aggregate principal amount of 4.04% Senior Notes due 2026 (the "October 2026 Notes"), and an additional $72.5 million in aggregate principal amount of October 2026 Notes in January 2022. The outstanding aggregate principal amount of the October 2026 Notes was $150.0 million as of both March 31, 2026 and December 31, 2025. For more information on the October 2026 Notes, including key terms and financial covenants, refer to *Note D — Debt* in the notes to the consolidated financial statements included in *Item 1. Consolidated Financial Statements* of this Quarterly Report on Form 10-Q.

On January 30, 2025, the Fund closed a follow-on public offering of 5,500,000 shares of its common stock, at the public offering price of $15.53 per share, in connection with the MSC Income Listing. In addition, on February 3, 2025, the Fund issued and sold 825,000 additional shares of its common stock, at the public offering price of $15.53 per share, pursuant to the underwriters' full exercise of their overallotment option. Net of underwriting discounts and commissions and offering costs, the Fund received net cash proceeds of $90.5 million in connection with the follow-on public equity offering.

MSC Income periodically invests excess cash balances into marketable securities. The primary investment objective of marketable securities is to generate incremental cash returns on excess cash balances prior to utilizing those funds for investment in Private Loan and LMM portfolio investments. Marketable securities generally consist of money market funds and certificates of deposit with financial institutions.

<u>[Table of contents](#i67b2a34b0c294631ad7f17e74adf23d3_7)</u>

If MSC Income's common stock trades below NAV per share, the Fund will generally not be able to issue additional common stock at the market price, unless the stockholders approve such a sale and the Board of Directors makes certain determinations. At the 2025 Annual Meeting of Stockholders, MSC Income received approval from its stockholders to have the flexibility, with the approval of the Board of Directors, to offer and sell shares of its common stock at a price below the current NAV per share until September 9, 2026. The Fund may also seek such authorization at future annual or special meetings of stockholders. Any decision to sell shares of MSC Income's common stock below the then current NAV per share of the common stock would be subject to the determination by the Board of Directors that such issuance is in the Fund's and its stockholders' best interests.

In order to satisfy the Code requirements applicable to a RIC, MSC Income intends to distribute to its stockholders, after consideration and application of its ability under the Code to carry forward certain excess undistributed taxable income from one tax year into the next tax year, substantially all of the Fund's taxable income.

In addition, as a BDC, MSC Income is allowed to borrow amounts such that its asset coverage ratio, or BDC asset coverage ratio, of its total assets to its total senior securities, which includes borrowings and any preferred stock the Fund may issue in the future, of at least 200% (or 150% if certain requirements are met). On January 29, 2025, the Board of Directors, including a "required majority" (as such term is defined in Section 57(o) of the 1940 Act) of the Board of Directors, approved the application of the reduced BDC asset coverage ratio. As a result the BDC asset coverage ratio requirement applicable to MSC Income decreased from 200% to 150% effective January 29, 2026. As of March 31, 2026, the Fund's BDC asset coverage ratio was 211%.

Although MSC Income has been able to secure access to additional liquidity, including through the Credit Facilities, the Master Note Purchase Agreement dated October 22, 2021 governing the October 2026 Notes (the "October 2026 Note Purchase Agreement") and the Master Note Purchase Agreement dated March 12, 2026 governing the May 2029 Notes (the "May 2029 Note Purchase Agreement"), there is no assurance that debt or equity capital will be available to the Fund in the future on favorable terms, or at all.

*Recently Issued or Adopted Accounting Standards*

From time to time, new accounting pronouncements are issued by the FASB or other standards-setting bodies that are adopted by MSC Income as of the specified effective date. The Fund believes that the impact of recently issued standards and any that are not yet effective will not have a material impact on its consolidated financial statements upon adoption. For a description of recently issued or adopted accounting standards, see *Note B.13. — Summary of Significant Accounting Policies — Recently Issued or Adopted Accounting Standards* in the notes to the consolidated financial statements included in *Item 1. Consolidated Financial Statements* of this Quarterly Report on Form 10-Q.

*Inflation*

Inflation has not historically had a significant effect on the Fund's results of operations in any of the reporting periods presented herein. However, the Fund's portfolio companies have experienced, specifically including over the last few years, as a result of recent geopolitical events, uncertainty with respect to the imposition of tariffs on and trade disputes with certain countries, supply chain and labor issues, and may continue to experience, the increasing impacts of inflation on their operating results, including periodic escalations in their costs for labor, raw materials and third-party services and required energy consumption. These issues and challenges related to inflation are receiving significant attention from the Fund's investment teams and the management teams of its portfolio companies as they work to manage these growing challenges. Prolonged or more severe impacts of inflation to portfolio companies could continue to affect their operating profits and, thereby, increase their borrowing costs, and as a result negatively impact their ability to service their debt obligations and/or reduce their available cash for distributions. In addition, these factors could have a negative effect on the fair value of investments in these portfolio companies. The combined impacts therefrom in turn could negatively affect the Fund's results of operations.

*Off-Balance Sheet Arrangements*

MSC Income may be a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financial needs of its portfolio companies. These instruments include commitments to extend credit and fund equity capital and involve, to varying degrees, elements of liquidity and credit risk in excess of the amount recognized in the Consolidated Balance Sheets. As of March 31, 2026, MSC Income had a total of $115.9 million in outstanding commitments comprised of (i) 59 investments with commitments to fund revolving loans that had not been fully drawn or term loans with additional commitments not yet funded and (ii) three investments with equity capital commitments that had not been fully called.

_________________

(1)Future interest payments on the Credit Facilities have not been included, as these amounts fluctuate over time depending on the current interest rates and amounts outstanding.

*Related Party Transactions and Agreements*

MSC Income has entered into agreements with the Adviser and/or certain of its affiliates and other parties whereby the Fund pays certain fees and reimbursements to these entities. In addition, the Fund makes payments to the Adviser for certain services that include the identification, execution and management of investments and also the management of day-to-day operations provided by the Adviser, pursuant to various agreements that MSC Income has entered into. See *Note J — Related Party Transactions* in the notes to the consolidated financial statements included in *Item 1. Consolidated Financial Statements* of this Quarterly Report on Form 10-Q for additional information regarding these related party transactions and agreements.

*Recent Developments*

In May 2026, the Board of Directors approved a change to its regular dividend payment frequency from quarterly to monthly beginning in July 2026. Additionally, MSC Income declared regular monthly dividends of $0.11 per share for each month of July, August and September 2026, or total regular monthly dividends of $0.33 per share for the third quarter of 2026, and a supplemental dividend of $0.03 per share, payable in September 2026, resulting in total dividends declared for the third quarter of 2026 of $0.36 per share.

**Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK**

MSC Income is subject to financial market risks, including changes in interest rates, and changes in interest rates may affect both the Fund's interest expense on the debt outstanding under the Credit Facilities and the interest income from portfolio investments. The Fund's risk management systems and procedures are designed to identify and analyze risk, to set appropriate policies and limits and to continually monitor these risks. The Fund's investment income will be affected by changes in various interest rate indices, including SOFR and Prime rates, to the extent that any debt investments include floating interest rates. See *Risk Factors — Risks Related to MSC Income's Business and Structure — MSC Income is subject to risks associated with the interest rate environment and changes in interest rates will affect its cost of capital, net investment income and the value of its investments.* and *Risk Factors — Risks Related to Leverage — Because MSC Income borrows money, the potential for gain or loss on amounts invested in MSC Income is magnified and may increase the risk of such investment.* included in the Fund's Annual Report on Form 10-K for the fiscal year ended December 31, 2025 for more information regarding risks associated with debt investments and borrowings that utilize SOFR or Prime as a reference rate.

The majority of MSC Income's debt investments are made with either fixed interest rates or floating rates that are subject to contractual minimum interest rates for the term of the investment. As of March 31, 2026, 77% of MSC Income's Investment Portfolio debt investments (at cost) bore interest at floating rates, 97% of which were subject to contractual minimum interest rates. As of March 31, 2026, 46% of MSC Income's debt obligations bore interest at fixed rates. MSC Income's interest expense will be affected by changes in the published SOFR in connection with the Credit Facilities; however, the interest rates on the outstanding October 2026 Notes and May 2029 Notes are fixed for the life of such debt. As of March 31, 2026, MSC Income had not entered into any interest rate hedging arrangements. Due to the Fund's limited use of derivatives, it has claimed an exclusion from the definition of the term "commodity pool operator" under the Commodity Exchange Act and, therefore, is not subject to registration or regulation as a pool operator thereunder. The Fund operates, and expects to continue to operate, as a "limited derivatives user" under Rule 18f-4 under the 1940 Act.

The approximate annualized increase or decrease in the components of net investment income due to hypothetical base rate changes in interest rates, assuming no changes in the Fund's investments and borrowings as of March 31, 2026, is as follows:

(1)The pro forma changes in the incentive fee on income expense are calculated pursuant to the terms set forth in the Advisory Agreement based upon the incentive fee on income expense for the first quarter of 2026, net of the voluntary permanent incentive fee on income waiver for the first quarter of 2026, in each case on an annualized basis, as adjusted for the pro forma change in pre-incentive fee net investment income resulting from the assumed interest income and interest expense changes reflected in the table, with no other changes in investment income or expenses and with the voluntary permanent incentive fee on income waiver assumed to remain at the first quarter of 2026 annualized amount. There is no guarantee that any incentive fee on income waivers will occur in the future, and any such waivers are entirely at the discretion of the Adviser.

Although MSC Income believes that this analysis is indicative of the impact of interest rate changes to net investment income as of March 31, 2026, the analysis does not take into consideration future changes in the credit market, credit quality or other business or economic developments that could affect net investment income. Accordingly, MSC Income can offer no assurances that actual results would not differ materially from the analysis above. The hypothetical results assume that all SOFR and Prime rate changes would be effective on the first day of the period. However, the contractual SOFR and Prime rate reset dates would vary throughout the period. The majority of the Fund's investments are based on contracts which reset quarterly, while the Corporate Facility and the SPV Facility reset on a monthly and quarterly basis, respectively. The hypothetical results would also be impacted by the changes in the amount of outstanding debt under the Credit Facilities (with an increase (decrease) in the debt outstanding under the Credit Facilities resulting in an (increase) decrease in the hypothetical interest expense).

**Item 4. CONTROLS AND PROCEDURES**

As of the end of the period covered by this Quarterly Report on Form 10-Q, MSC Income carried out an evaluation, under the supervision and with the participation of its management, including the Chief Executive Officer, President, Chief Financial Officer, General Counsel and Chief Accounting Officer, of the effectiveness of the design and operation of disclosure controls and procedures (as defined in Rule 13a-15 of the Exchange Act). Based on that evaluation, MSC Income's Chief Executive Officer, President, Chief Financial Officer, General Counsel and Chief Accounting Officer have concluded that the current disclosure controls and procedures are effective in timely alerting them of material information relating to MSC Income that is required to be disclosed in the reports the Fund files or submits under the Exchange Act. There have been no changes in MSC Income's internal control over financial reporting that occurred during the quarter ended March 31, 2026 that have materially affected, or are reasonably likely to materially affect, the Fund's internal control over financial reporting.

**PART II—OTHER INFORMATION**

**Item 1. LEGAL PROCEEDINGS**

MSC Income, the Adviser and/or Main Street may, from time to time, be involved in litigation arising out of the Fund's operations in the normal course of business or otherwise. Furthermore, third parties may seek to impose liability on the Fund, the Adviser and/or Main Street in connection with the activities of the Fund's portfolio companies. While the outcome of any current legal proceedings cannot at this time be predicted with certainty, MSC Income does not expect any current matters will materially affect the Fund's, the Adviser's or Main Street's financial condition or results of operations; however, there can be no assurance whether any pending or future legal proceedings will have a material adverse effect on the Fund's, the Adviser's or Main Street's financial condition or results of operations in any future reporting period.

**Item 1A. RISK FACTORS**

You should carefully consider the risks described below and all other information contained in this Quarterly Report on Form 10-Q, including MSC Income's interim consolidated financial statements and the related notes thereto, before making a decision to purchase MSC Income's securities. The risks and uncertainties described below are not the only ones facing the Fund.
