Organization, Consolidation and Presentation of Financial Statements [Abstract]
ORGANIZATION AND BASIS OF PRESENTATION	ORGANIZATION AND BASIS OF PRESENTATION 1. Organization MSC Income Fund, Inc. (“MSIF” or, together with its consolidated subsidiaries, “MSC Income Fund” or the “Company”) 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”) and secondarily focused on providing customized long-term debt and equity capital solutions to lower middle market (“LMM”) companies (its “LMM investment strategy”). MSC Income Fund’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 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 United States. MSC Income Fund also seeks to partner with entrepreneurs, business owners and management teams and generally provides “one-stop” debt and equity financing solutions within its LMM investment strategy. Through its LMM investment strategy, MSC Income Fund primarily invests in secured debt investments, equity investments, warrants and other securities of LMM companies typically based in the United States. MSC Income Fund 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 Fund’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 Fund has generally stopped making new Middle Market investments and expects its Middle Market investment portfolio to continue to decline in future periods as its existing Middle Market investments are repaid or sold. MSC Income Fund’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. The “Investment Portfolio,” as used herein, refers to all of MSC Income Fund’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 business development company (“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, MSIF’s stockholders approved the appointment of MSC Adviser I, LLC (the “Adviser”), which is wholly-owned by Main Street Capital Corporation (“Main Street”), a New York Stock Exchange listed BDC, as MSIF’s investment adviser and administrator under an Investment Advisory and Administrative Services Agreement dated October 30, 2020 (the “Investment Advisory Agreement”). In such role, the Adviser has the responsibility to manage the business of MSC Income Fund, including the responsibility to identify, evaluate, negotiate and structure prospective investments, make investment and portfolio management decisions, monitor MSC Income Fund’s Investment Portfolio (as defined below) and provide ongoing administrative services. 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 “we,” “us,” “our,” the “Company” and “MSC Income Fund” refer to MSIF and its consolidated subsidiaries, which include the Taxable Subsidiaries and the Structured Subsidiaries. 2. Basis of Presentation MSC Income Fund’s consolidated financial statements are prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”). The Company 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 Fund’s consolidated financial statements include the accounts of MSIF and its consolidated subsidiaries. The Investment Portfolio as used herein, refers to all of MSC Income Fund’s investments in Private Loan portfolio companies, investments in LMM portfolio companies, investments in Middle Market portfolio companies and Other Portfolio investments. MSC Income Fund’s results of operations for the three and nine months ended September 30, 2024 and 2023, cash flows for the nine months ended September 30, 2024 and 2023, and financial position as of September 30, 2024 and December 31, 2023, are presented on a consolidated basis. The effects of all intercompany transactions between MSIF and its consolidated subsidiaries have been eliminated in consolidation. The accompanying unaudited consolidated financial statements of MSC Income Fund 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, 2023. 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 and nine months ended September 30, 2024 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 Fund is precluded from consolidating other entities in which MSC Income Fund 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 Fund holds a controlling interest in an operating company that provides all or substantially all of its services directly to MSC Income Fund. Accordingly, as noted above, MSC Income Fund’s consolidated financial statements include the financial position and operating results for the Taxable Subsidiaries and the Structured Subsidiaries. MSC Income Fund has determined that none of its portfolio investments qualify for this exception. Therefore, MSC Income Fund’s Investment Portfolio is carried on the Consolidated Balance Sheets at fair value, as discussed further in Note B.1. — Summary of Significant Accounting Policies — Valuation of the Investment Portfolio , 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 Fund 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 Fund 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 Fund 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 Fund has excluded consideration of any voting securities or board appointment rights held by Main Street or third-party investment funds advised by the Adviser.

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 1. Valuation of the Investment Portfolio MSC Income Fund accounts for its Investment Portfolio at fair value. As a result, MSC Income Fund 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 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. MSC Income Fund’s portfolio strategy calls for it to invest primarily in debt securities issued by Private Loan companies and illiquid debt and equity securities issued by LMM companies. MSC Income Fund also maintains a legacy portfolio of investments in Middle Market companies and a limited portfolio of Other Portfolio investments. MSC Income Fund’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 Fund 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 Fund’s valuation policies and processes are intended to provide a consistent basis for determining the fair value of MSC Income Fund’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 Fund 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 Fund 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 methodology (“Waterfall”) 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 Fund primarily uses quoted prices in the valuation process. MSC Income Fund 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 Fund generally calculates the fair value of the investment primarily based on the net asset value (“NAV”) of the 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 Fund’s portfolio investments estimate the value of the investment as if MSC Income Fund were to sell, or exit, the investment as of the measurement date. These valuation approaches consider the value associated with MSC Income Fund’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 Fund 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 Fund 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. Under the Waterfall valuation method, MSC Income Fund 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 Fund analyzes various factors including the portfolio company’s historical and projected financial results. Due to SEC deadlines for MSC Income Fund’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 Fund also analyzes the impact of exposure to litigation, loss of customers or other contingencies. After determining the appropriate enterprise value, MSC Income Fund 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 Fund 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 Fund believes is consistent with its past transaction history and standard industry practices. Under the Yield-to-Maturity valuation method, MSC Income Fund 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 Fund’s estimate of the expected repayment date of its debt securities is generally the maturity date of the instrument, as MSC Income Fund 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 Fund will generally use the value determined by the Yield-to-Maturity analysis as the fair value for that security; however, because of MSC Income Fund’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 Fund 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 Fund 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 Fund 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 Fund that would affect that fund’s NAV, including, but not limited to, fair values for individual investments held by the fund if MSC Income Fund holds the same investment or for a publicly traded investment. In addition, in determining the fair value of the investment, MSC Income Fund considers whether adjustments to the NAV are necessary in certain circumstances, based on the analysis of any restrictions on redemption of MSC Income Fund’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 Fund’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 Fund 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 Fund, 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 and recommendations and an assurance certification regarding MSC Income Fund’s determinations of the fair value of its Private Loan portfolio company investments. The Financial Advisory Firm is generally consulted relative to MSC Income Fund’s investments in each Private Loan portfolio company at least once every calendar year, and for MSC Income Fund’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 Fund 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 Fund’s investment in a Private Loan portfolio company is determined to be insignificant relative to the total Investment Portfolio. MSC Income Fund 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 17 and 14 Private Loan portfolio companies during the three months ended September 30, 2024 and 2023, respectively, representing 24% and 21% of the total Private Loan portfolio at fair value as of September 30, 2024 and 2023, respectively. A total of 58 Private Loan portfolio companies were reviewed and certified by the Financial Advisory Firm during the trailing twelve months ended September 30, 2024, representing 78% of the total Private Loan portfolio at fair value as of September 30, 2024. Excluding its investments in Private Loan portfolio companies that, as of September 30, 2024, had not been in the Investment Portfolio for at least twelve months subsequent to the initial investment and its investments in Private Loan portfolio companies that were not reviewed because the investment is valued based upon third-party quotes or other independent pricing, 96% of the Private Loan portfolio at fair value was reviewed and certified by the Financial Advisory Firm during the trailing twelve months ended September 30, 2024. For valuation purposes, all of MSC Income Fund’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 Fund 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 Fund, 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 Fund’s determinations of the fair value of its LMM portfolio company investments. The Financial Advisory Firm is generally consulted relative to MSC Income Fund’s investments in each LMM portfolio company at least once every calendar year, and for MSC Income Fund’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 Fund 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 Fund’s investment in a LMM portfolio company is determined to be insignificant relative to the total Investment Portfolio. MSC Income Fund 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 12 LMM portfolio companies during each of the three months ended September 30, 2024 and 2023, representing 22% and 25% of the total LMM portfolio at fair value as of September 30, 2024 and 2023, respectively. A total of 48 LMM portfolio companies were reviewed and certified by the Financial Advisory Firm during the trailing twelve months ended September 30, 2024, representing 93% of the total LMM portfolio at fair value as of September 30, 2024. Excluding its investments in LMM portfolio companies that, as of September 30, 2024, had not been in the Investment Portfolio for at least twelve months subsequent to the initial investment or 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 September 30, 2024. For valuation purposes, all of MSC Income Fund’s Middle Market portfolio investments are non-control investments. To the extent sufficient observable inputs are available to determine fair value, MSC Income Fund 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 Fund 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 Fund 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 (94% and 97% as of September 30, 2024 and December 31, 2023, respectively) of the Middle Market portfolio investments (i) are valued using third-party quotes or other independent pricing services or (ii) MSC Income Fund 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 Fund’s Other Portfolio investments are non-control investments. MSC Income Fund’s Other Portfolio investments comprised 2.2% and 2.3% of MSC Income Fund’s Investment Portfolio at fair value as of September 30, 2024 and December 31, 2023, 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 Fund generally determines the fair value of these investments using the NAV valuation method. Due to the inherent uncertainty in the valuation process, MSC Income Fund’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 Fund determines the fair value of each individual investment and records changes in fair value as unrealized appreciation or depreciation. MSC Income Fund 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 Fund’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 Main Street’s and the Adviser’s executive officers, to serve as the Board of Directors’ valuation designee. MSC Income Fund believes its Investment Portfolio as of September 30, 2024 and December 31, 2023 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 Fund pursuant to valuation policies and procedures approved and overseen by MSC Income Fund’s Board of Directors, 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. Macroeconomic factors, including pandemics, risk of recession, inflation, supply chain constraints or disruptions, geopolitical disruptions 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 Fund’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 Fund’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 September 30, 2024 and December 31, 2023, the Company had $31.2 million and $20.8 million, respectively, of cash equivalents invested in AAA-rated money market funds pending investment in the Company’s primary investment strategies. These highly liquid investments are included in the Consolidated Schedule of Investments. As of September 30, 2024 and December 31, 2023, cash balances totaling $16.5 million and $9.0 million, respectively, exceeded Federal Deposit Insurance Corporation insurance protection levels, subjecting the Company to risk related to the uninsured balance. 4. Interest, Dividend and Fee Income MSC Income Fund 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 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 MSC Income Fund otherwise does not expect the debtor to be able to service its debt obligation, MSC Income Fund 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 Fund removes it from non-accrual status. As of September 30, 2024, investments on non-accrual status comprised 2.6% of MSC Income Fund’s total Investment Portfolio at fair value and 6.5% at cost. As of December 31, 2023, investments on non-accrual status comprised 1.1% of MSC Income Fund’s total Investment Portfolio at fair value and 4.0% at cost. MSC Income Fund 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 (as discussed in Note B.7. — 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 Fund may not have collected the PIK interest and cumulative dividends in cash. MSC Income Fund 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 September 30, 2024 and 2023, (i) 6.7% and 4.6%, respectively, of MSC Income Fund’s total investment income was attributable to PIK interest income not paid currently in cash and (ii) 0.1% of MSC Income Fund’s total investment income in each period was attributable to cumulative dividend income not paid currently in cash. For the nine months ended September 30, 2024 and 2023, (i) 5.4% and 3.9%, respectively, of MSC Income Fund’s total investment income was attributable to PIK interest income not paid currently in cash and (ii) 0.1% of MSC Income Fund’s total investment income in each period was attributable to cumulative dividend income not paid currently in cash. MSC Income Fund 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 Fund received from its Investment Portfolio in each of the periods presented is as follows: Three Months Ended Nine Months Ended 2024 2023 2024 2023 (dollars in thousands) Interest, fee and dividend income: Interest income $ 30,236 $ 29,400 $ 88,154 $ 86,791 Dividend income 2,485 2,399 8,964 7,862 Fee income 756 552 4,255 1,973 Total interest, fee and dividend income $ 33,477 $ 32,351 $ 101,373 $ 96,626 5. Deferred Financing Costs Deferred financing costs include commitment fees and other direct costs incurred in connection with arranging MSC Income Fund’s borrowings. Deferred financing costs incurred in connection with MSC Income Fund’s multi-year revolving Credit Facilities (as defined in Note D — Debt ) have been capitalized as an asset. Deferred financing costs incurred in connection with the Series A Notes (as defined in Note D — Debt ) are reflected as a direct deduction from the principal amount outstanding. 6. Unearned Income—Debt Origination Fees and Original Issue Discount and Discounts / Premiums to Par Value MSC Income Fund 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 Fund 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 Fund 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 Fund 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 Fund 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 Fund 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. To maintain RIC tax treatment (as discussed in Note B.7. — 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 Fund may not have collected the interest income. For the three months ended September 30, 2024 and 2023, 3.0% and 2.6%, respectively, and for the nine months ended September 30, 2024 and 2023, 2.8% and 2.6%, respectively, of MSC Income Fund’s total investment income was attributable to interest income from the accretion of discounts associated with debt investments, net of any premium amortization. 7. 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 Fund. The Taxable Subsidiaries permit MSC Income Fund 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 Fund for U.S. GAAP financial reporting purposes, and the portfolio investments held by the Taxable Subsidiaries are included in MSC Income Fund’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 Fund’s consolidated financial statements. The

FAIR VALUE HIERARCHY FOR INVEST

FAIR VALUE HIERARCHY FOR INVESTMENTS—PORTFOLIO COMPOSITION	9 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUE HIERARCHY FOR INVESTMENTS—PORTFOLIO COMPOSITION	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 Fund accounts for its investments at fair value. Fair Value Hierarchy In accordance with ASC 820, MSC Income Fund 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 Fund’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 Fund has the ability to access (examples include investments in active exchange-traded equity securities and investments in most U.S. government and agency securities). 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: • Quoted prices for similar assets in active markets (for example, investments in restricted stock); • Quoted prices for identical or similar assets in non-active markets (for example, investments in thinly traded public companies); • Pricing models whose inputs are observable for substantially the full term of the investment (for example, market interest rate indices); and • 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 September 30, 2024 and December 31, 2023, MSC Income Fund’s Private Loan portfolio investments primarily consisted of investments in secured 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 Fund’s Private Loan portfolio investments were categorized as Level 3 as of September 30, 2024 and December 31, 2023. As of September 30, 2024 and December 31, 2023, all of MSC Income Fund’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 Fund’s LMM portfolio investments were categorized as Level 3 as of September 30, 2024 and December 31, 2023. As of September 30, 2024 and December 31, 2023, MSC Income Fund’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 Fund’s Middle Market portfolio investments were categorized as Level 3 as of September 30, 2024 and December 31, 2023. As of September 30, 2024 and December 31, 2023, MSC Income Fund’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 Fund’s Other Portfolio investments were categorized as Level 3 as of September 30, 2024 and December 31, 2023. As of September 30, 2024 and December 31, 2023, 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: • 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 numbers; • Current and projected financial condition of the portfolio company; • Current and projected ability of the portfolio company to service its debt obligations; • Type and amount of collateral, if any, underlying the investment; • Current financial ratios (e.g., fixed charge coverage ratio, interest coverage ratio and net debt/EBITDA ratio) applicable to the investment; • Current liquidity of the investment and related financial ratios (e.g., current ratio and quick ratio); • Pending debt or capital restructuring of the portfolio company; • Projected operating results of the portfolio company; • Current information regarding any offers to purchase the investment; • Current ability of the portfolio company to raise any additional financing as needed; • Changes in the economic environment which may have a material impact on the operating results of the portfolio company; • Internal occurrences that may have an impact (both positive and negative) on the operating performance of the portfolio company; • Qualitative assessment of key management; • Contractual rights, obligations or restrictions associated with the investment; and • 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 Fund’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 Fund’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. The following tables provide a summary of the significant unobservable inputs used to fair value MSC Income Fund’s Level 3 portfolio investments as of September 30, 2024 and December 31, 2023: Type of Fair Value as of September 30, (in thousands) Valuation Technique Significant Range(3) Weighted-Average Median(3) Equity investments $ 244,788 Discounted cash flow WACC 11.3% - 22.6% 14.5 % 15.0 % Market comparable / Enterprise value EBITDA multiple (1) 4.0x - 9.2x (2) 7.0x 6.5x Debt investments $ 879,495 Discounted cash flow Risk adjusted discount factor (5) 9.8% - 17.5% (2) 13.6 % 12.9 % Expected principal recovery percentage 0.2% - 100.0% 99.7 % 100.0 % Debt investments $ 38,344 Market approach Third-party quote 27.5 - 99.0 83.1 91.5 Total Level 3 investments $ 1,162,627 _____________________ (1) EBITDA may include proforma adjustments and/or other add-backs based on specific circumstances related to each investment.

As of September 30, 2024 and December 31, 2023, MSC Income Fund's investments at fair value were categorized as follows in the fair value hierarchy for ASC 820 purposes: Fair Value Measurements (in thousands) As of September 30, 2024 Fair Value Quoted Prices in Significant Other Significant Private Loan portfolio investments $ 679,863 $ — $ — $ 679,863 LMM portfolio investments 411,030 — — 411,030 Middle Market portfolio investments 46,062 — — 46,062 Other Portfolio investments 25,672 — — 25,672 Total investments $ 1,162,627 $ — $ — $ 1,162,627 Fair Value Measurements (in thousands) As of December 31, 2023 Fair Value Quoted Prices in Significant Other Significant Private Loan portfolio investments $ 595,326 $ — $ — $ 595,326 LMM portfolio investments 386,956 — — 386,956 Middle Market portfolio investments 85,990 — — 85,990 Other Portfolio investments 24,623 — — 24,623 Total investments $ 1,092,895 $ — $ — $ 1,092,895 Investment Portfolio Composition MSC Income Fund’s principal investment objective is to maximize its investment portfolio’s total return by generating current income from its debt investments and 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 Fund seeks to achieve its investment objective primarily through its Private Loan and LMM investment strategies. MSC Income Fund’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 $20 million. MSC Income Fund’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 Fund’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 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 MSC Income Fund’s LMM investment strategy is focused on investments in secured debt and equity in privately held, LMM companies based in the United States. MSC Income Fund’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 $20 million. The LMM debt investments are typically secured by a first priority lien on the assets of the portfolio company, can include either fixed or floating interest rate terms and generally have a term of between five MSC Income Fund also maintains a legacy portfolio of investments in Middle Market companies. MSC Income Fund’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 Fund has generally stopped making new Middle Market investments and expects its Middle Market investment portfolio to continue to decline in future periods as its existing Middle Market investments are repaid or sold. MSC Income Fund’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 MSC Income Fund’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 Fund may incur indirect fees and expenses to third party managers. For Other Portfolio investments, MSC Income Fund generally receives distributions related to the assets held by the portfolio company. Those assets are typically expected to be realized over a five 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 and nine months ended September 30, 2024 and 2023, MSC Income Fund did not record investment income from any single portfolio company in excess of 10% of total investment income. The following tables provide a summary of MSC Income Fund’s investments in the Private Loan, LMM and Middle Market portfolios as of September 30, 2024 and December 31, 2023 (this information excludes Other Portfolio investments, which are discussed further below). As of September 30, 2024 Private Loan LMM (a) Middle Market (dollars in millions) Number of portfolio companies 84 55 11 Fair value $ 679.9 $ 411.0 $ 46.1 Cost $ 700.0 $ 340.5 $ 73.0 Debt investments as a % of portfolio (at cost) 95.6 % 70.8 % 88.9 % Equity investments as a % of portfolio (at cost) 4.4 % 29.2 % 11.1 % % of debt investments at cost secured by first priority lien 99.9 % 99.9 % 99.9 % Weighted-average annual effective yield (b) 12.7 % 13.2 % 14.1 % Average EBITDA (c) $ 33.2 $ 10.0 $ 44.3 ___________________ (a) As of September 30, 2024, MSC Income Fund had equity ownership in all of its LMM portfolio companies, and the average fully diluted equity ownership in those portfolio companies was 9%. (b) The weighted-average annual effective yields were computed using the effective interest rates for all debt investments as of September 30, 2024, including amortization of deferred debt origination fees and accretion of original issue discount but excluding fees payable upon repayment of the debt instruments and any debt investments on non-accrual status, and are weighted based upon the principal amount of each applicable debt investment as of September 30, 2024. The weighted-average annual effective yield on MSC Income Fund’s debt portfolio as of September 30, 2024 including debt investments on non-accrual status was 12.1% for its Private Loan portfolio, 11.8% for its LMM portfolio and 9.4% for its Middle Market portfolio. The weighted-average annual effective yield is not reflective of what an investor in shares of MSC Income Fund’s common stock will realize on its investment because it does not reflect MSC Income Fund’s utilization of debt capital in its capital structure, MSC Income Fund’s expenses or any sales load paid by an investor. (c) The average EBITDA is calculated using a weighted-average for the Private Loan and Middle Market portfolios and a simple average for the LMM portfolio. These calculations exclude certain portfolio companies, including two Private Loan portfolio companies, two LMM portfolio companies and one Middle Market portfolio company, as EBITDA is not a meaningful valuation metric for MSC Income 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. As of December 31, 2023 Private Loan LMM (a) Middle Market (dollars in millions) Number of portfolio companies 78 50 16 Fair value $ 595.3 $ 387.0 $ 86.0 Cost $ 586.4 $ 315.7 $ 114.7 Debt investments as a % of portfolio (at cost) 94.1 % 70.2 % 93.1 % Equity investments as a % of portfolio (at cost) 5.9 % 29.8 % 6.9 % % of debt investments at cost secured by first priority lien 100.0 % 99.9 % 100.0 % Weighted-average annual effective yield (b) 13.1 % 13.0 % 13.0 % Average EBITDA (c) $ 30.5 $ 8.8 $ 74.2 ___________________ (a) As of December 31, 2023, MSC Income Fund had equity ownership in all of its LMM portfolio companies, and the average fully diluted equity ownership in those portfolio companies was 9%. (b) The weighted-average annual effective yields were computed using the effective interest rates for all debt investments as of December 31, 2023, including amortization of deferred debt origination fees and accretion of original issue discount but excluding fees payable upon repayment of the debt instruments 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, 2023. The weighted-average annual effective yield on MSC Income Fund’s debt portfolio as of December 31, 2023 including debt investments on non-accrual status was 12.6% for its Private Loan portfolio, 13.0% for its LMM portfolio and 9.9% for its Middle Market portfolio. The weighted-average annual effective yield is not reflective of what an investor in shares of MSC Income Fund’s common stock will realize on its investment because it does not reflect MSC Income Fund’s utilization of debt capital in its capital structure, MSC Income Fund’s expenses or any sales load paid by an investor. (c) The average EBITDA is calculated using a weighted-average for the Private Loan and Middle Market portfolios and a simple average for the LMM portfolio. These calculations exclude certain portfolio companies, including one Private Loan portfolio company, as EBITDA is not a meaningful valuation metric for MSC Income Fund’s investment in this portfolio company, and those portfolio companies whose primary purpose is to own real estate. For the three months ended September 30, 2024 and 2023, MSC Income Fund achieved an annualized total return on investments of 10.5% and 12.0%, respectively. For the nine months ended September 30, 2024 and 2023, MSC Income Fund achieved an annualized total return on investments of 12.4% and 12.9%, respectively. For the year ended December 31, 2023, MSC Income Fund achieved a total return on investments of 13.6%. Total return on investments is calculated using the interest, dividend and fee income, as well as the realized and unrealized change in fair value of the Investment Portfolio for the specified period. MSC Income Fund’s total return on investments is not reflective of what an investor in shares of MSC Income Fund’s common stock will realize on its investment because it does not reflect MSC Income Fund ’ s utilization of debt capital in its capital structure, MSC Income Fund ’ s expenses or any sales load paid by an investor. As of September 30, 2024, MSC Income Fund had Other Portfolio investments in six entities, spread across four investment managers, collectively totaling $25.7 million in fair value and $19.1 million in cost basis and which comprised 2.2% and 1.7% of MSC Income Fund’s Investment Portfolio at fair value and cost, respectively. As of December 31, 2023, MSC Income Fund had Other Portfolio investments in six entities, spread across four investment managers, collectively totaling $24.6 million in fair value and $21.5 million in cost basis and which comprised 2.3% and 2.1% of MSC Income Fund’s Investment Portfolio at fair value and cost, respectively.

As of September 30, 2024 and December 31, 2023, MSC Income Fund had no portfolio investment that was greater than 10% of the Investment Portfolio at fair value. Unconsolidated Significant Subsidiaries In accordance with Rules 3-09 and 4-08(g) of Regulation S-X, MSC Income Fund 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 Fund must utilize to determine if any of MSC Income Fund’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 Fund 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 MSC Income Fund’s investment in the Control Investment by the value of MSC Income Fund’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 Fund’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 Fund to include (1) separate audited financial statements of an unconsolidated majority-owned subsidiary (Control Investments in which MSC Income Fund 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 September 30, 2024 and December 31, 2023, MSC Income Fund had no single investment that qualified as a significant subsidiary under either the investment or income tests.

In connection with the Corporate Facility, MSIF has made customary representations and warranties and is required to comply with various covenants, reporting requirements and other customary requirements for similar credit facilities. Effective April 27, 2023, the reference rate under the Corporate Facility was amended from LIBOR to SOFR plus an applicable credit spread adjustment of 0.10%.

DIVIDENDS, DISTRIBUTIONS AND TAXABLE INCOME	9 Months Ended

Income Tax Disclosure [Abstract]
DIVIDENDS, DISTRIBUTIONS AND TAXABLE INCOME	DIVIDENDS, DISTRIBUTIONS AND TAXABLE INCOME MSC Income Fund currently pays quarterly dividends to its stockholders. Future quarterly dividends, if any, will be determined by its Board of Directors on a quarterly basis. MSC Income Fund paid or accrued dividends to its common stockholders of $14.5 million, or $0.18 per share, during the three months ended September 30, 2024, and $43.7 million, or $0.545 per share, during the nine months ended September 30, 2024, compared to $14.0 million, or $0.175 per share, during the three months ended September 30, 2023, and $42.0 million, or $0.525 per share, during the nine months ended September 30, 2023. 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 Fund’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. Listed below is a reconciliation of “Net increase in net assets resulting from operations” to taxable income and to total distributions declared to common stockholders for the nine months ended September 30, 2024 and 2023. Nine Months Ended September 30, 2024 2023 (estimated, dollars in thousands) Net increase in net assets resulting from operations $ 36,089 $ 44,869 Net unrealized (appreciation) depreciation 24,656 (30,415) Income tax provision 6,150 3,189 Pre-tax book income not consolidated for tax purposes (9,867) (676) Book income and tax income differences, including debt origination, structuring fees, dividends, realized gains and changes in estimates (9,989) 20,099 Estimated taxable income (1) 47,039 37,066 Taxable income earned in prior year and carried forward for distribution in current year 14,745 20,674 Taxable income earned prior to period end and carried forward for distribution next period (32,538) (29,705) Dividend accrued as of period end and paid in the following period 14,478 14,002 Total distributions accrued or paid to common stockholders $ 43,724 $ 42,037 ________________ (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 Fund. The Taxable Subsidiaries permit MSC Income Fund 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 Fund’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 Fund’s consolidated financial statements. The income tax provision for MSC Income Fund is generally composed of (i) deferred tax expense, 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 and excise taxes on MSC Income Fund’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 Fund’s Consolidated Statements of Operations. MSC Income Fund’s provision for income taxes was comprised of the following for the three and nine months ended September 30, 2024 and 2023: Three Months Ended September 30, Nine Months Ended September 30, 2024 2023 2024 2023 (dollars in thousands) Current tax expense (benefit): Federal $ 761 $ (39) $ 1,145 $ 15 State 397 337 810 565 Excise 491 133 570 374 Total current tax expense 1,649 431 2,525 954 Deferred tax expense (benefit): Federal 652 292 3,395 2,533 State 133 (750) 230 (298) Total deferred tax expense (benefit) 785 (458) 3,625 2,235 Total income tax provision (benefit) $ 2,434 $ (27) $ 6,150 $ 3,189 The net deferred tax liability as of September 30, 2024 and December 31, 2023 was $6.9 million and $3.3 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.

Share-Based Payment Arrangement [Abstract]
SHARE REPURCHASES	SHARE REPURCHASES Under the terms of its share repurchase program, MSC Income Fund offers to purchase shares at the NAV per share on the repurchase date. The amount of shares of MSC Income Fund’s common stock to be repurchased during any calendar quarter may be equal to the lesser of (i) the number of shares of common stock MSC Income Fund could repurchase with the proceeds it received from the issuance of common stock under MSC Income Fund’s dividend reinvestment plan or (ii) 2.5% of the weighted-average number of shares of common stock outstanding in the prior four calendar quarters. Repurchase offers are currently limited to the number of shares of common stock MSC Income Fund can repurchase with 90% of the cash retained as a result of issuances of common stock under its dividend reinvestment plan. At the discretion of the Board of Directors, MSC Income Fund may also use cash on hand, cash available from borrowings and cash from the sale of investments as of the end of the applicable period to repurchase shares. MSC Income Fund’s Board of Directors may amend, suspend or terminate the share repurchase program upon 30 days’ notice. In addition to its share repurchase program, beginning in the second quarter of 2023, MSC Income Fund began periodically offering to complete modified Dutch auction tender offers (“Dutch Auction Tenders”), pursuant to which MSC Income Fund offered to purchase up to a specified amount of shares of its common stock at the lowest clearing purchase price elected by participating stockholders within a specified range that allowed MSC Income Fund to purchase the maximum amount offered. In such Dutch Auction Tenders all shares purchased are purchased at the clearing purchase price. SEC rules permit MSC Income Fund to increase the number of shares accepted for purchase in any Dutch Auction Tender by up to 2% of MSC Income Fund’s outstanding shares without amending the offer. MSC Income Fund has no obligation to continue to offer Dutch Auction Tenders in the future. On February 5, 2024, MSC Income Fund commenced a modified “Dutch Auction” tender offer (the “February 2024 Dutch Auction Tender Offer”) pursuant to the Offer to Purchase, dated February 5, 2024, which expired on March 4, 2024. Pursuant to the February 2024 Dutch Auction Tender Offer, MSC Income Fund repurchased 357,143 shares on March 8, 2024 at a price of $7.00 per share for an aggregate cost of $2.5 million, excluding fees and expenses related to the February 2024 Dutch Auction Tender Offer. On May 17, 2024, MSC Income Fund commenced a modified “Dutch Auction” tender offer (the “May 2024 Dutch Auction Tender Offer”) pursuant to the Offer to Purchase, dated May 17, 2024, which expired on June 20, 2024. Pursuant to the May 2024 Dutch Auction Tender Offer, MSC Income Fund repurchased 333,333 shares on June 25, 2024 at a price of $6.00 per share for an aggregate cost of $2.0 million, excluding fees and expenses related to the May 2024 Dutch Auction Tender Offer. For the three months ended September 30, 2024 and 2023, MSC Income Fund funded $4.0 million and $4.2 million, respectively, for shares of its common stock tendered for repurchase under the share repurchase program. For the three months ended September 30, 2024, MSC Income Fund did not tender any shares of its common stock for repurchase through its Dutch auction tender offers. For the three months ended September 30, 2023, MSC Income Fund funded $2.8 million for shares of its common stock tendered for repurchase through its Dutch auction tender offers. For the nine months ended September 30, 2024 and 2023, MSC Income Fund funded $12.3 million and $12.5 million, respectively, for shares of its common stock tendered for repurchase under the share repurchase program. For the nine months ended September 30, 2024 and 2023, MSC Income Fund funded $4.5 million and $5.1 million, respectively, for shares of its common stock tendered for repurchase through its Dutch auction tender offers.

Equity [Abstract]
DIVIDEND REINVESTMENT PLAN	DIVIDEND REINVESTMENT PLAN MSC Income Fund’s dividend reinvestment plan (the “DRIP”) provides for the reinvestment of dividends on behalf of its stockholders. As a result, if MSC Income Fund declares a cash dividend, its stockholders who have “opted in” to the DRIP will have their cash dividend automatically reinvested into additional shares of MSC Income Fund common stock. The number of shares of common stock to be issued to a stockholder under the DRIP shall be determined by dividing the total dollar amount of the distribution payable to such stockholder by a price per share of common stock determined by MSC Income Fund’s Board of Directors or a committee thereof, in its sole discretion, that is (i) not less than the NAV per share of common stock determined in good faith by the Board of Directors or a committee thereof, in its sole discretion, within 48 hours prior to the payment of the distribution and (ii) not more than 2.5% greater than the NAV per share as of such date. Summarized DRIP information for the nine months ended September 30, 2024 and 2023 is as follows: Nine Months Ended September 30, 2024 2023 (dollars in thousands) DRIP participation $ 13,578 $ 13,864 Shares issued for DRIP 1,706,763 1,767,289

The Company 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 Company does not expect any further capital will be called on its commitment for follow on investments. As a result, the Company has excluded those commitments from this table. MSC Income Fund 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 Fund follows a process to manage its liquidity and ensure that it has available capital to fund its unfunded commitments as necessary. MSC Income Fund had no unrealized appreciation or depreciation on the outstanding unfunded commitments as of September 30, 2024. MSC Income Fund 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 try to impose liability on MSC Income Fund 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 Fund 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 legal proceedings will have a material adverse effect on MSC Income Fund’s financial condition or results of operations in any future reporting period.

Related Party Transactions [Abstract]
RELATED PARTY TRANSACTIONS	RELATED PARTY TRANSACTIONS 1. Advisory Agreements and Conditional Expense Reimbursement Waivers On October 30, 2020, MSC Income Fund entered into the Investment Advisory Agreement with the Adviser, which states that the Adviser will oversee the management of MSC Income Fund’s activities and is responsible for making investment decisions with respect to, and providing day‑to‑day management and administration of, MSC Income Fund’s Investment Portfolio. The Investment Advisory Agreement was most recently re-approved by the Board of Directors, including a majority of members who are not “interested” persons (as defined by the 1940 Act) of MSC Income Fund or the Adviser, on July 17, 2024. Pursuant to the Investment Advisory Agreement, MSC Income Fund pays the Adviser a base management fee and incentive fees as compensation for the services described above. The base management fee is calculated at an annual rate of 1.75% of MSC Income Fund’s average gross assets. The term “gross assets” means total assets of MSC Income Fund as disclosed on MSC Income Fund’s Consolidated Balance Sheets. “Average gross assets” are calculated based on MSC Income Fund’s gross assets at the end of the two most recently completed calendar quarters. The base management fee is payable quarterly in arrears. The base management fee is expensed as incurred. The incentive fee under the Investment Advisory Agreement consists of two parts. The first part, referred to as the subordinated incentive fee on income, is 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 is equal to 20.0% of MSC Income Fund’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). 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 MSC Income Fund receives from portfolio companies) accrued during the calendar quarter, minus MSC Income Fund’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 includes, 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 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. For purposes of this fee, adjusted capital means cumulative gross proceeds generated from sales of MSC Income Fund’s common stock (including proceeds from MSC Income Fund’s DRIP) reduced for non-liquidating distributions, other than distributions of profits, paid to MSC Income Fund’s stockholders and amounts paid for share repurchases pursuant to MSC Income Fund’s share repurchase program. The subordinated incentive fee on income is expensed in the quarter in which it is incurred. The calculation of the subordinated incentive fee on income for each quarter is as follows: • No subordinated incentive fee on income shall be payable to the Adviser in any calendar quarter in which MSC Income Fund’s Pre-Incentive Fee Net Investment Income does not exceed the hurdle rate of 1.875% (or 7.5% annualized) on adjusted capital; • 100% of MSC Income Fund’s Pre-Incentive Fee Net Investment Income, if any, that exceeds the hurdle rate but is less than or equal to 2.34375% in any calendar quarter (9.375% annualized) shall be 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 20.0% on all of MSC Income 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 2.34375% (9.375% annualized) in any calendar quarter; and • For any quarter in which MSC Income Fund’s Pre-Incentive Fee Net Investment Income exceeds 2.34375% (9.375% annualized), the subordinated incentive fee on income shall equal 20.0% of the amount of MSC Income Fund’s Pre-Incentive Fee Net Investment Income, as the hurdle rate and catch-up will have been achieved. The second part of the incentive fee, referred to as the incentive fee on capital gains, is an incentive fee on realized capital gains earned from the portfolio of MSC Income Fund and is determined and payable in arrears as of the end of each calendar year (or upon termination of the Investment Advisory Agreement). This fee equals 20.0% of MSC Income Fund’s incentive fee capital gains, which equals MSC Income Fund’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 Fund estimates the incentive fee on capital gains and accrues the fee based on a hypothetical liquidation of its portfolio. Therefore, the accrual includes 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 is neither earned nor payable to the Adviser until such time it is realized. For the three months ended September 30, 2024 and 2023, MSC Income Fund incurred base management fees of $5.3 million and $5.0 million, respectively. For the three months ended September 30, 2024 and 2023, MSC Income Fund incurred subordinated incentive fees on income of $2.1 million and $2.6 million, respectively. For each of the three months ended September 30, 2024 and 2023, MSC Income Fund did not incur any capital gains incentive fees. For the nine months ended September 30, 2024 and 2023, MSC Income Fund incurred base management fees of $15.5 million and $14.8 million, respectively. For the nine months ended September 30, 2024 and 2023, MSC Income Fund incurred subordinated incentive fees on income of $9.4 million and $8.9 million, respectively. For each of the nine months ended September 30, 2024 and 2023, MSC Income Fund did not incur any capital gains incentive fees. Pursuant to the Investment Advisory Agreement, MSC Income Fund is required to pay or reimburse the Adviser for administrative services expenses, which include all costs and expenses related to MSC Income Fund’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 include, but are not limited to, the cost of an Adviser’s personnel performing accounting and compliance functions and other administrative services on behalf of MSC Income Fund. The Adviser waived reimbursement of all Internal Administrative Services expenses from October 30, 2020 through December 31, 2021. On January 1, 2022, the Adviser assumed responsibility of certain administrative services that were previously provided for MSC Income Fund 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. For the three months ended September 30, 2024 and 2023, MSC Income Fund incurred Internal Administrative Services expenses before expense waivers of $2.4 million and $2.2 million, respectively. For the three months ended September 30, 2024 and 2023, the Adviser waived the reimbursements of Internal Administrative Services expenses of $2.2 million and $2.0 million, respectively. For the nine months ended September 30, 2024 and 2023, MSC Income Fund incurred Internal Administrative Services expenses before expense waivers of $7.2 million and $6.8 million, respectively. For the nine months ended September 30, 2024 and 2023, the Adviser waived the reimbursements of Internal Administrative Services expenses of $6.7 million and $6.3 million, respectively. Waived Internal Administrative Services expenses are permanently waived and are not subject to future reimbursement. 2. Offering Costs In accordance with MSC Income Fund’s previous investment advisory agreement with the previous investment adviser (“HMS Adviser”), MSC Income Fund reimbursed HMS Adviser for any offering costs that were paid on MSC Income Fund’s behalf, which consisted of, among other costs, actual legal, accounting, bona fide out-of-pocket itemized and detailed due diligence costs, printing, filing fees, transfer agent costs, postage, escrow fees, advertising and sales literature and other costs incurred in connection with the offering of MSC Income Fund’s common stock, including through MSC Income Fund’s DRIP. HMS Adviser was responsible for the payment of offering costs to the extent they exceeded 1.5% of the aggregate gross stock offering proceeds. Pursuant to the transaction whereby the Adviser became the investment adviser to MSC Income Fund, HMS Adviser agreed to permanently waive reimbursement of organizational and offering expenses except for $0.6 million which remained payable to HMS Adviser and would be reimbursed as part of future issuances of common stock by MSC Income Fund. For the three months ended June 30, 2023, MSC Income Fund reimbursed HMS Adviser $0.1 million in connection with stock issuances. MSC Income Fund’s reimbursement obligation to HMS Adviser for organizational and offering expenses was fully repaid as of June 30, 2023. 3. Indemnification The Investment Advisory Agreement provides that the Adviser and its officers, directors, controlling persons and any other person or entity affiliated with it acting as MSC Income Fund’s agent are entitled to indemnification (including reasonable attorneys’ fees and amounts reasonably paid in settlement) for any liability or loss suffered by such indemnitee, and such indemnitee will be held harmless for any loss or liability suffered by MSC Income Fund, if (i) the indemnitee has determined, in good faith, that the course of conduct which caused the loss or liability was in MSC Income Fund’s best interests, (ii) the indemnitee was acting on behalf of or performing services for MSC Income Fund, (iii) the liability or loss suffered was not the result of negligence, willful malfeasance, bad faith or misconduct by the indemnitee or an affiliate thereof acting as MSC Income Fund’s agent and (iv) the indemnification or agreement to hold the indemnitee harmless is only recoverable out of MSC Income Fund’s net assets and not from MSC Income Fund’s stockholders. 4. Co-Investment In the ordinary course of business, MSC Income Fund enters into transactions with other parties that may be considered related party transactions. MSC Income Fund 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 Fund. If such affiliations are found to exist, MSC Income Fund 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. MSC Income Fund has received an exemptive order from the SEC permitting co-investments among MSC Income Fund, Main Street and other funds and clients advised by the Adviser in certain negotiated transactions where co-investing would otherwise be prohibited under the 1940 Act. MSC Income Fund has made co-investments, and in the future intends to continue to make co-investments with Main Street and other funds and clients advised by the Adviser, in accordance with the conditions of the order. The order requires, among other things, that the Adviser and Main Street consider whether each such investment opportunity is appropriate for MSC Income Fund, Main Street and the other funds and clients advised by the Adviser, as applicable, and if it is appropriate, to propose an allocation of the investment opportunity between such parties. Because the Adviser is wholly-owned by Main Street and is not managing MSC Income Fund’s investment activities as its sole activity, this may provide the Adviser an incentive to allocate opportunities to other participating funds and clients instead of MSC Income Fund. However, the Adviser has policies and procedures in place to manage this conflict, including oversight by the independent members of the Board of Directors. 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 Fund also co-invests in syndicated deals and other transactions where price is the only negotiated point by MSC Income Fund and its affiliates. 5. Other Related Party Transactions On August 1, 2024, the Company sold 250,627 shares of its common stock to Main Street at $7.98 per share, the price at which the Company issued new shares in connection with reinvestments of the August 1, 2024 dividend pursuant to the DRIP, for total proceeds to the Company of $2.0 million. The issuance and sale were made pursuant to the exemption from registration under Section 4(a)(2) of the Securities Act and were 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 Company or the Adviser.

Subsequent Events [Abstract]
SUBSEQUENT EVENTS	SUBSEQUENT EVENTS Our management has evaluated subsequent events through the date of issuance of the consolidated financial statements, and identified the following to report: On November 1, 2024, the Company repurchased 512,730 shares of its common stock validly tendered and not withdrawn on the terms set forth in the tender offer statement on Schedule TO and Offer to Purchase filed with the SEC on September 26, 2024. The shares were repurchased at a price of $7.74 per share, which was the Company’s NAV per share as of November 1, 2024, for an aggregate purchase price of $4.0 million (an amount equal to 90% of the proceeds the Company received from the issuance of shares under the Company’s DRIP from the November 1, 2024 dividend payment). On November 8, 2024, the Company entered into an amendment to the Corporate Facility to, among other things: (i) extend the revolving period from September 2025 to November 2028, (ii) extend the final maturity date from March 2026 to May 2029 and (iii) reduce the interest rate, subject to MSC Income Fund’s election to (a) SOFR plus 2.05% or (b) the base rate plus 1.05%. On November 13, 2024, the Board of Directors declared a quarterly dividend of $0.18 per share payable on January 31, 2025 to stockholders of record as of December 31, 2024. The Company has scheduled a special meeting of stockholders on December 2, 2024 to consider a series of proposals that the Company believes will position it to potentially effect a listing of the Company’s shares of common stock on a national securities exchange (such as the New York Stock Exchange) (a “Listing”) if and when market conditions make it desirable to do so and it is otherwise in the Company’s best interest. On November 13, 2024, the Board of Directors, including the independent directors, unanimously approved suspending the Company’s share repurchase program in anticipation of a Listing and the opportunity for enhanced liquidity a Listing is expected to provide the Company’s stockholders. The share repurchase program will ultimately terminate upon a Listing.

General Description of Registrant [Abstract]
Investment Objectives and Practices [Text Block]	OVERVIEW OF OUR BUSINESS Our principal investment objective is to maximize our investment portfolio’s total return by generating current income from our debt investments and current income and capital appreciation from our equity and equity-related investments, including warrants, convertible securities and other rights to acquire equity securities in a portfolio company. We seek to achieve our investment objective through our Private Loan and LMM investment strategies. Our 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. Our LMM investment strategy involves investments in companies that generally have annual revenues between $10 million and $150 million and annual EBITDA between $3 million and $20 million. Our Private Loan and LMM investments generally range in size from $1 million to $20 million. Private Loan investments primarily consist of debt securities that have primarily been originated directly by our Adviser or, to a lesser extent, through our 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. Our Private Loan investments are typically made in a company owned by or in the process of being acquired by a private equity fund. Our 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. We may also co-invest with Main Street and the private equity fund in the equity securities of our Private Loan portfolio companies. We also seek 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 creates the opportunity for us to meet the financing needs of LMM companies while also negotiating favorable transaction terms and equity participation. Our ability to invest across a company’s capital structure, from secured loans to equity securities, allows us to offer portfolio companies a comprehensive suite of financing options, or a “one-stop” financing solution. We believe that providing customized, “one-stop” financing solutions is important and valuable to LMM portfolio companies. We generally seek to partner directly with entrepreneurs, management teams and business owners in making our LMM investments. Our LMM portfolio debt investments are generally secured by a first lien on the assets of the portfolio company and typically have a term of between five and seven years from the original investment date. We also maintain a legacy portfolio of investments in larger middle market (“Middle Market”) companies (our “Middle Market investment portfolio”). Our Middle Market investments are generally debt investments in companies owned by private equity funds that were originally issued through a syndication financing process. We have generally stopped making new Middle Market investments and expect our Middle Market investment portfolio to continue to decline in future periods as existing Middle Market investments are repaid or sold. Our 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. Our other portfolio (“Other Portfolio”) investments primarily consist of investments that are not consistent with the typical profiles for our Private Loan, LMM or Middle Market portfolio investments, including investments in unaffiliated investment companies and private funds managed by third parties. In our Other Portfolio, we may incur indirect fees and expenses to third party managers. The “Investment Portfolio,” as used herein, refers to all of our Private Loan portfolio investments, LMM portfolio investments, Middle Market portfolio investments and Other Portfolio investments. Our 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 our view of the current economic fundamentals, our ability to identify new investment opportunities that meet our investment criteria, and our ability to consummate the identified opportunities and our 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 our portfolio debt investments on non-accrual status will directly impact future investment income. While we intend to grow our portfolio and our investment income over the long term, our growth and our operating results may be more limited during depressed economic periods. However, we intend to appropriately manage our cost structure and liquidity position based on applicable economic conditions and our investment outlook. The level of realized gains or losses and unrealized appreciation or depreciation on our investments will also fluctuate depending upon portfolio activity, economic conditions and the performance of our individual portfolio companies. The changes in realized gains and losses and unrealized appreciation or depreciation could have a material impact on our operating results. We have received an exemptive order from the SEC permitting co-investments among us, Main Street and other funds and clients advised by our Adviser in certain negotiated transactions where co-investing would otherwise be prohibited under the 1940 Act. We have made co-investments with, and in the future intend to continue to make co-investments with Main Street and other funds and clients advised by our Adviser, in accordance with the conditions of the order. The order requires, among other things, that we and our Adviser consider whether each such investment opportunity is appropriate for us, Main Street and the other funds and clients advised by our Adviser, as applicable, and if it is appropriate, to propose an allocation of the investment opportunity between such parties. Because our Adviser is wholly-owned by Main Street and is not managing our investment activities as its sole activity, this may provide our Adviser an incentive to allocate opportunities to Main Street, other participating funds and other clients instead of us. However, both we and our Adviser have policies and procedures in place to manage this conflict, including oversight by the independent members of our Board of Directors. In addition to the co-investment program described above, we also co-invest in syndicated deals and other transactions where price is the only negotiated point by us and our affiliates.

The Series A Notes bear a fixed interest rate of 4.04% per year and will mature on October 30, 2026, unless redeemed, purchased or prepaid prior to such date by the Company in accordance with their terms. Interest on the Series A Notes is due semiannually on April 30 and October 30 of each year. The Series A Notes may be redeemed in whole or in part at any time or from time to time at MSC Income Fund’s option at par plus accrued interest to the prepayment date and, if applicable, a make-whole premium. In addition, MSC Income Fund is obligated to offer to prepay the Series A Notes at par plus accrued and unpaid interest up to, but excluding, the date of prepayment, if certain change in control events occur. In the event that a Below Investment Grade Event (as defined in the Note Purchase Agreement) occurs, the Series A Notes will bear interest at a fixed rate of 5.04% per year from the date of the occurrence of the Below Investment Grade Event to and until the date on which the Below Investment Grade Event ends. The Series A Notes are general unsecured obligations of MSIF that rank pari passu with all outstanding and future unsecured unsubordinated indebtedness issued by MSIF.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	9 Months Ended
	Sep. 30, 2024
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation MSC Income Fund’s consolidated financial statements are prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”). The Company 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 Fund’s consolidated financial statements include the accounts of MSIF and its consolidated subsidiaries. The Investment Portfolio as used herein, refers to all of MSC Income Fund’s investments in Private Loan portfolio companies, investments in LMM portfolio companies, investments in Middle Market portfolio companies and Other Portfolio investments. MSC Income Fund’s results of operations for the three and nine months ended September 30, 2024 and 2023, cash flows for the nine months ended September 30, 2024 and 2023, and financial position as of September 30, 2024 and December 31, 2023, are presented on a consolidated basis. The effects of all intercompany transactions between MSIF and its consolidated subsidiaries have been eliminated in consolidation. The accompanying unaudited consolidated financial statements of MSC Income Fund 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, 2023. 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 and nine months ended September 30, 2024 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	Principles of Consolidation Under ASC 946, MSC Income Fund is precluded from consolidating other entities in which MSC Income Fund 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 Fund holds a controlling interest in an operating company that provides all or substantially all of its services directly to MSC Income Fund. Accordingly, as noted above, MSC Income Fund’s consolidated financial statements include the financial position and operating results for the Taxable Subsidiaries and the Structured Subsidiaries. MSC Income Fund has determined that none of its portfolio investments qualify for this exception. Therefore, MSC Income Fund’s Investment Portfolio is carried on the Consolidated Balance Sheets at fair value, as discussed further in Note B.1. — Summary of Significant Accounting Policies — Valuation of the Investment Portfolio , 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 and Valuation of the Investment Portfolio	Portfolio Investment Classification MSC Income Fund 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 Fund 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 Fund 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 Fund has excluded consideration of any voting securities or board appointment rights held by Main Street or third-party investment funds advised by the Adviser. Valuation of the Investment Portfolio MSC Income Fund accounts for its Investment Portfolio at fair value. As a result, MSC Income Fund 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 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. MSC Income Fund’s portfolio strategy calls for it to invest primarily in debt securities issued by Private Loan companies and illiquid debt and equity securities issued by LMM companies. MSC Income Fund also maintains a legacy portfolio of investments in Middle Market companies and a limited portfolio of Other Portfolio investments. MSC Income Fund’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 Fund 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 Fund’s valuation policies and processes are intended to provide a consistent basis for determining the fair value of MSC Income Fund’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 Fund 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 Fund 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 methodology (“Waterfall”) 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 Fund primarily uses quoted prices in the valuation process. MSC Income Fund 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 Fund generally calculates the fair value of the investment primarily based on the net asset value (“NAV”) of the 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 Fund’s portfolio investments estimate the value of the investment as if MSC Income Fund were to sell, or exit, the investment as of the measurement date. These valuation approaches consider the value associated with MSC Income Fund’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 Fund 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 Fund 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. Under the Waterfall valuation method, MSC Income Fund 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 Fund analyzes various factors including the portfolio company’s historical and projected financial results. Due to SEC deadlines for MSC Income Fund’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 Fund also analyzes the impact of exposure to litigation, loss of customers or other contingencies. After determining the appropriate enterprise value, MSC Income Fund 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 Fund 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 Fund believes is consistent with its past transaction history and standard industry practices. Under the Yield-to-Maturity valuation method, MSC Income Fund 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 Fund’s estimate of the expected repayment date of its debt securities is generally the maturity date of the instrument, as MSC Income Fund 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 Fund will generally use the value determined by the Yield-to-Maturity analysis as the fair value for that security; however, because of MSC Income Fund’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 Fund 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 Fund 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 Fund 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 Fund that would affect that fund’s NAV, including, but not limited to, fair values for individual investments held by the fund if MSC Income Fund holds the same investment or for a publicly traded investment. In addition, in determining the fair value of the investment, MSC Income Fund considers whether adjustments to the NAV are necessary in certain circumstances, based on the analysis of any restrictions on redemption of MSC Income Fund’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 Fund’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 Fund 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 Fund, 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 and recommendations and an assurance certification regarding MSC Income Fund’s determinations of the fair value of its Private Loan portfolio company investments. The Financial Advisory Firm is generally consulted relative to MSC Income Fund’s investments in each Private Loan portfolio company at least once every calendar year, and for MSC Income Fund’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 Fund 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 Fund’s investment in a Private Loan portfolio company is determined to be insignificant relative to the total Investment Portfolio. MSC Income Fund 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 17 and 14 Private Loan portfolio companies during the three months ended September 30, 2024 and 2023, respectively, representing 24% and 21% of the total Private Loan portfolio at fair value as of September 30, 2024 and 2023, respectively. A total of 58 Private Loan portfolio companies were reviewed and certified by the Financial Advisory Firm during the trailing twelve months ended September 30, 2024, representing 78% of the total Private Loan portfolio at fair value as of September 30, 2024. Excluding its investments in Private Loan portfolio companies that, as of September 30, 2024, had not been in the Investment Portfolio for at least twelve months subsequent to the initial investment and its investments in Private Loan portfolio companies that were not reviewed because the investment is valued based upon third-party quotes or other independent pricing, 96% of the Private Loan portfolio at fair value was reviewed and certified by the Financial Advisory Firm during the trailing twelve months ended September 30, 2024. For valuation purposes, all of MSC Income Fund’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 Fund 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 Fund, 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 Fund’s determinations of the fair value of its LMM portfolio company investments. The Financial Advisory Firm is generally consulted relative to MSC Income Fund’s investments in each LMM portfolio company at least once every calendar year, and for MSC Income Fund’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 Fund 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 Fund’s investment in a LMM portfolio company is determined to be insignificant relative to the total Investment Portfolio. MSC Income Fund 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 12 LMM portfolio companies during each of the three months ended September 30, 2024 and 2023, representing 22% and 25% of the total LMM portfolio at fair value as of September 30, 2024 and 2023, respectively. A total of 48 LMM portfolio companies were reviewed and certified by the Financial Advisory Firm during the trailing twelve months ended September 30, 2024, representing 93% of the total LMM portfolio at fair value as of September 30, 2024. Excluding its investments in LMM portfolio companies that, as of September 30, 2024, had not been in the Investment Portfolio for at least twelve months subsequent to the initial investment or 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 September 30, 2024. For valuation purposes, all of MSC Income Fund’s Middle Market portfolio investments are non-control investments. To the extent sufficient observable inputs are available to determine fair value, MSC Income Fund 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 Fund 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 Fund 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 (94% and 97% as of September 30, 2024 and December 31, 2023, respectively) of the Middle Market portfolio investments (i) are valued using third-party quotes or other independent pricing services or (ii) MSC Income Fund 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 Fund’s Other Portfolio investments are non-control investments. MSC Income Fund’s Other Portfolio investments comprised 2.2% and 2.3% of MSC Income Fund’s Investment Portfolio at fair value as of September 30, 2024 and December 31, 2023, 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 Fund generally determines the fair value of these investments using the NAV valuation method. Due to the inherent uncertainty in the valuation process, MSC Income Fund’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 Fund determines the fair value of each individual investment and records changes in fair value as unrealized appreciation or depreciation. MSC Income Fund 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 Fund’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 Main Street’s and the Adviser’s executive officers, to serve as the Board of Directors’ valuation designee. MSC Income Fund believes its Investment Portfolio as of September 30, 2024 and December 31, 2023 approximates fair value as of those dates based on the markets in which it operates and other conditions in existence on those reporting dates.
Use of Estimates	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 Fund pursuant to valuation policies and procedures approved and overseen by MSC Income Fund’s Board of Directors, 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. Macroeconomic factors, including pandemics, risk of recession, inflation, supply chain constraints or disruptions, geopolitical disruptions 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 Fund’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 Fund’s Investment Portfolio has and may continue to experience increased volatility.
Cash and Cash Equivalents	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 September 30, 2024 and December 31, 2023, the Company had $31.2 million and $20.8 million, respectively, of cash equivalents invested in AAA-rated money market funds pending investment in the Company’s primary investment strategies. These highly liquid investments are included in the Consolidated Schedule of Investments.
Interest	Interest, Dividend and Fee Income MSC Income Fund 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 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 MSC Income Fund otherwise does not expect the debtor to be able to service its debt obligation, MSC Income Fund 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 Fund removes it from non-accrual status.
Dividend	MSC Income Fund 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 (as discussed in Note B.7. — Summary of Significant Accounting Policies — Income Taxes
Fee Income	MSC Income Fund 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.
Deferred Financing Costs	Deferred Financing Costs Deferred financing costs include commitment fees and other direct costs incurred in connection with arranging MSC Income Fund’s borrowings. Deferred financing costs incurred in connection with MSC Income Fund’s multi-year revolving Credit Facilities (as defined in Note D — Debt ) have been capitalized as an asset. Deferred financing costs incurred in connection with the Series A Notes (as defined in Note D — Debt ) are reflected as a direct deduction from the principal amount outstanding.
Unearned Income—Debt Origination Fees and Original Issue Discount and Discounts / Premiums to Par Value	Unearned Income—Debt Origination Fees and Original Issue Discount and Discounts / Premiums to Par Value MSC Income Fund 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 Fund 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 Fund 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 Fund 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 Fund 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 Fund 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. To maintain RIC tax treatment (as discussed in Note B.7. — Summary of Significant Accounting Policies — Income Taxes
Income Taxes	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 Fund. The Taxable Subsidiaries permit MSC Income Fund 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 Fund for U.S. GAAP financial reporting purposes, and the portfolio investments held by the Taxable Subsidiaries are included in MSC Income Fund’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 Fund’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 Fund’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.
Net Realized Gains or Losses and Net Unrealized Appreciation or Depreciation	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.
Fair Value of Financial Instruments	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 Fund 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 Fund’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 Fund discloses the estimated fair value of its debt obligations in Note D — Debt. To estimate the fair value of MSC Income Fund’s Series A Notes as disclosed in Note D — Debt , MSC Income Fund 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 Fund’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.

Fair Value Measurement	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 Fund accounts for its investments at fair value. Fair Value Hierarchy In accordance with ASC 820, MSC Income Fund 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 Fund’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 Fund has the ability to access (examples include investments in active exchange-traded equity securities and investments in most U.S. government and agency securities). 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: • Quoted prices for similar assets in active markets (for example, investments in restricted stock); • Quoted prices for identical or similar assets in non-active markets (for example, investments in thinly traded public companies); • Pricing models whose inputs are observable for substantially the full term of the investment (for example, market interest rate indices); and • 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 September 30, 2024 and December 31, 2023, MSC Income Fund’s Private Loan portfolio investments primarily consisted of investments in secured 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 Fund’s Private Loan portfolio investments were categorized as Level 3 as of September 30, 2024 and December 31, 2023. As of September 30, 2024 and December 31, 2023, all of MSC Income Fund’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 Fund’s LMM portfolio investments were categorized as Level 3 as of September 30, 2024 and December 31, 2023. As of September 30, 2024 and December 31, 2023, MSC Income Fund’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 Fund’s Middle Market portfolio investments were categorized as Level 3 as of September 30, 2024 and December 31, 2023. As of September 30, 2024 and December 31, 2023, MSC Income Fund’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.

(b) The weighted-average annual effective yields were computed using the effective interest rates for all debt investments as of September 30, 2024, including amortization of deferred debt origination fees and accretion of original issue discount but excluding fees payable upon repayment of the debt instruments and any debt investments on non-accrual status, and are weighted based upon the principal amount of each applicable debt investment as of September 30, 2024. The weighted-average annual effective yield on MSC Income Fund’s debt portfolio as of September 30, 2024 including debt investments on non-accrual status was 12.1% for its Private Loan portfolio, 11.8% for its LMM portfolio and 9.4% for its Middle Market portfolio. The weighted-average annual effective yield is not reflective of what an investor in shares of MSC Income Fund’s common stock will realize on its investment because it does not reflect MSC Income Fund’s utilization of debt capital in its capital structure, MSC Income Fund’s expenses or any sales load paid by an investor. (c) The average EBITDA is calculated using a weighted-average for the Private Loan and Middle Market portfolios and a simple average for the LMM portfolio. These calculations exclude certain portfolio companies, including two Private Loan portfolio companies, two LMM portfolio companies and one Middle Market portfolio company, as EBITDA is not a meaningful valuation metric for MSC Income 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.

The weighted-average annual effective yield is not reflective of what an investor in shares of MSC Income Fund’s common stock will realize on its investment because it does not reflect MSC Income Fund’s utilization of debt capital in its capital structure, MSC Income Fund’s expenses or any sales load paid by an investor. (c) The average EBITDA is calculated using a weighted-average for the Private Loan and Middle Market portfolios and a simple average for the LMM portfolio. These calculations exclude certain portfolio companies, including one Private Loan portfolio company, as EBITDA is not a meaningful valuation metric for MSC Income Fund’s investment in this portfolio company, and those portfolio companies whose primary purpose is to own real estate.
