2 • Realized a gain of $11.6 million on the exit of investments in Centre Technologies Holdings, LLC, a LMM portfolio company In commenting on the Fund’s operating results for the second quarter of 2026, Dwayne L. Hyzak, MSC Income’s Chief Executive Officer, stated, “We are pleased with the Fund’s performance in the second quarter, which resulted in an annualized return on equity of 15.9%. The positive results included significant net fair value appreciation of the Fund’s investment portfolio, including net fair value appreciation of both the private loan and lower middle market investment portfolios and including the benefit of a material realized gain in the Fund’s lower middle market investment portfolio. Based upon the quality of the Fund’s existing investment portfolio, together with the favorable liquidity position and the current investment pipeline, we remain excited about our future expectations for the Fund.” Second Quarter 2026 Operating Results The following table provides a summary of the Fund’s operating results for the second quarter of 2026: Three Months Ended June 30, 2026 2025 Change Change (%) (dollars in thousands, except per share amounts) Interest income $ 30,040 $ 29,349 $ 691 2% Dividend income 3,829 4,956 (1,127) (23)% Fee income 1,831 1,338 493 37% Total investment income $ 35,700 $ 35,643 $ 57 —% Net investment income $ 11,999 $ 16,307 $ (4,308) (26)% Net investment income per share $ 0.26 $ 0.35 $ (0.09) (26)% Adjusted net investment income (1) $ 14,948 $ 16,307 $ (1,359) (8)% Adjusted net investment income per share (1) $ 0.33 $ 0.35 $ (0.02) (6)% Adjusted net investment income before taxes (2) $ 16,323 $ 17,306 $ (983) (6)% Adjusted net investment income before taxes per share (2) $ 0.36 $ 0.37 $ (0.01) (3)% Net increase in net assets resulting from operations $ 29,272 $ 16,289 $ 12,983 80% Net increase in net assets resulting from operations per share $ 0.65 $ 0.35 $ 0.30 86% Return on equity - quarter annualized (4) 15.9% 9.0% 6.9% 77% The $0.1 million increase in total investment income in the second quarter of 2026 from the comparable period of the prior year was principally attributable to (i) a $0.7 million increase in interest income, primarily due to higher average levels of income producing investment portfolio debt investments, partially offset by a decrease in interest rates, primarily resulting from decreases in benchmark index rates on floating rate investment portfolio debt investments, and the negative impact from investment portfolio debt investments on non-accrual status and (ii) a $0.5 million increase in fee income, primarily due to an increase in fee income from the refinancing and prepayment of investment portfolio debt investments. These increases were partially offset by a $1.1 million decrease in dividend income, primarily due to a $0.9 million decrease in dividend income from the Fund’s LMM portfolio companies. The $0.1 million increase in total investment income in the second quarter of 2026 includes the impact of an increase of $1.4 million in certain income considered less consistent or non- recurring, primarily related to increases of (i) $0.7 million in such fee income and (ii) $0.5 million in such dividend income, in each case when compared to the same period in 2025.

3 Total expenses, net of waivers, increased by $4.0 million, or 21.8%, to $22.3 million in the second quarter of 2026 from $18.3 million for the same period in 2025. This increase was principally attributable to (i) a $2.9 million increase in the ending accrual for the accrued capital gains incentive fee(3) as of June 30, 2026, (ii) a $1.2 million increase in interest expense and (iii) a $0.4 million increase in base management fees, partially offset by a $0.6 million decrease in incentive fee on income, net of waivers. The increase in the capital gains incentive fee accrual(3) was due to the net fair value appreciation of the Fund’s investments in the second quarter of 2026. The increase in interest expense was primarily related to (i) an increase in average borrowings outstanding used to fund a portion of the growth of the Fund’s investment portfolio and (ii) an increased weighted-average interest rate on the Fund’s unsecured debt obligations, driven by the issuance of the May 2029 Notes in the first quarter of 2026, partially offset by a decreased weighted-average interest rate on the Credit Facilities due to decreases in benchmark floating index interest rates (with the May 2029 Notes and the Credit Facilities each defined in the Liquidity and Capital Resources section below). The increase in base management fees was primarily the result of the Fund’s increased average total assets. The decrease in incentive fee on income, net of waivers, was the result of (a) a decrease in the gross calculated incentive fee on income of $0.3 million, primarily driven by a decrease in pre-incentive NII, and (b) a $0.3 million voluntary waiver of incentive fee on income by the Adviser (defined below). The Fund’s ratio of total non-interest operating expenses, excluding incentive fees, net of waivers, as a percentage of quarterly average total assets, or the Operating Expenses to Assets Ratio, was 1.9% on an annualized basis for the second quarter of 2026, consistent with the second quarter of 2025. The $4.3 million decrease in NII in the second quarter of 2026 from the comparable period of the prior year was principally attributable to an increase in total expenses, net of waivers, partially offset by an increase in total investment income, each as discussed above. NII on a per share basis decreased by $0.09 per share for the second quarter of 2026 as compared to the second quarter of 2025, to $0.26 per share, reflecting the impact of the $0.07 per share capital gains incentive fee accrual(3) in the second quarter of 2026. The $1.4 million, or $0.02 per share, decrease in ANII(1) in the second quarter of 2026 to $14.9 million, or $0.33 per share, from $16.3 million, or $0.35 per share, in the second quarter of 2025 was principally attributable to the same factors noted above for the change in NII, but excluding the impact of the $2.9 million increase in the capital gains incentive fee accrual.(3) The per share changes in NII and ANII(1) in the second quarter of 2026 from the comparable period of the prior year include the impact of a 3.6% decrease in the weighted-average shares outstanding, primarily due to shares repurchased by the Fund, partially offset by shares issued through the dividend reinvestment plan, in each case since the beginning of the comparable period of the prior year. NII and ANII(1) on a per share basis in the second quarter of 2026 each include an increase of $0.03 per share resulting from an increase in investment income considered less consistent or non-recurring in nature compared to the second quarter of 2025, as discussed above.

4 The $29.3 million net increase in net assets resulting from operations in the second quarter of 2026 represents a $13.0 million increase from the second quarter of 2025. This increase was primarily the result of an $18.1 million increase in the net fair value change of the Fund’s portfolio investments resulting from the net impact of net realized gains/losses and net unrealized appreciation/depreciation, with the increase resulting from a net fair value increase of $19.0 million in the second quarter of 2026 compared to a net fair value increase of $0.9 million in the comparable period of the prior year, partially offset by (i) a $4.3 million decrease in NII as discussed above and (ii) a $0.8 million increase in the net tax provision on the net fair value change of the portfolio investments, resulting from a net tax provision of $1.7 million in the second quarter of 2026 compared to a net tax provision of $0.9 million in the comparable period of the prior year. The $19.0 million net fair value increase in the second quarter of 2026 was the result of a net realized gain of $9.9 million and net unrealized appreciation (including the reversal of net fair value appreciation recognized in prior periods due to the net realized gain in the quarter) of $9.1 million. The $0.9 million net fair value increase in the second quarter of 2025 was the result of a net realized gain of $4.8 million, partially offset by net unrealized depreciation of $3.9 million. The $9.9 million net realized gain from investments for the second quarter of 2026 was primarily the result of an $11.6 million realized gain on the full exit of a LMM portfolio investment, partially offset by a $1.9 million realized loss on the restructure of a private loan portfolio investment. The following table provides a summary of the total net unrealized appreciation of $9.1 million for the second quarter of 2026: Three Months Ended June 30, 2026 PrivateLoan LMM (a) MiddleMarket Other Total (in millions) Accounting reversals of net unrealized (appreciation) depreciation recognized in prior periods due to net realized (gains / income) losses recognized during the current period $ 1.3 $ (11.9) $ — $ — $ (10.6) Net unrealized appreciation (depreciation) relating to portfolio investments 11.2 10.3 (1.6) (0.2) 19.7 Total net unrealized appreciation (depreciation) relating to portfolio investments $ 12.5 $ (1.6) $ (1.6) $ (0.2) $ 9.1 (a)Includes unrealized appreciation on 27 LMM portfolio investments and unrealized depreciation on 17 LMM portfolio investments. Liquidity and Capital Resources As of June 30, 2026, the Fund had aggregate liquidity of $210.5 million, including (i) $28.1 million in cash and cash equivalents and (ii) $182.4 million of aggregate unused capacity under the Fund’s corporate revolving credit facility (the “Corporate Facility”) and the Fund’s special purpose vehicle revolving credit facility (the “SPV Facility” and, together with the Corporate Facility, the “Credit Facilities”), which the Fund maintains to support its investment and operating activities. Several details regarding the Fund’s capital structure as of June 30, 2026 are as follows: • The SPV Facility included $300.0 million in total commitments plus an accordion feature that allows the Fund to request an increase in the total commitments under the facility to up to $450.0 million. • $249.0 million in outstanding borrowings under the SPV Facility, with an interest rate of 5.9% based on the applicable Secured Overnight Financing Rate (“SOFR”) effective for the contractual reset date of July 1, 2026. • The Corporate Facility included $245.0 million in total commitments from a diversified group of seven participating lenders, plus an accordion feature that allows the Fund to request an increase in the total commitments under the facility to up to $300.0 million.

5 • $113.0 million in outstanding borrowings under the Corporate Facility, with an interest rate of 5.7% based on the applicable SOFR effective for the contractual reset date of July 1, 2026. • $150.0 million of unsecured notes outstanding that bear interest at a rate of 4.04% per year (the “October 2026 Notes”). The October 2026 Notes mature on October 30, 2026 and may be redeemed in whole or in part at any time at the Fund’s option subject to certain make-whole provisions. • $150.0 million of May 2029 Notes outstanding that bear interest at a rate of 6.34% per year. The May 2029 Notes mature on May 31, 2029 and may be redeemed in whole or in part at any time at the Fund’s option subject to certain make-whole provisions. • The Fund maintains an investment grade rating from Kroll Bond Rating Agency, LLC (“KBRA”) of BBB- with a stable outlook. • The Fund’s net asset value totaled $748.8 million, or $16.51 per share. • The Fund’s debt-to-equity ratio was 0.88x as of June 30, 2026. Share Purchase Plan In August 2026, the Fund’s board of directors authorized a share repurchase plan pursuant to which the Fund may repurchase up to $20.0 million of shares of its common stock for a period beginning in September 2026 and ending in February 2027, at times when the market price per share of the common stock is trading below the most recently reported net asset value per share of the common stock by certain pre-determined levels. Pursuant to such authorization, the Fund intends to enter into a share repurchase plan (the “Fund Rule 10b5-1 Stock Repurchase Plan”) to facilitate the repurchase of up to the full $20.0 million of shares of its common stock authorized under the share repurchase program. The repurchases of any shares pursuant to the Fund Rule 10b5-1 Stock Repurchase Plan will be implemented in accordance with Rule 10b5-1 and Rule 10b-18 under the Securities Exchange Act of 1934 (the “Exchange Act”). In August 2026, Main Street Capital Corporation (NYSE: MAIN) (“Main Street”), parent company of the Adviser, authorized a plan pursuant to which Main Street may purchase up to $20.0 million of shares of the Fund’s common stock in the open market during the same time period, pursuant to the terms of a share purchase plan (the “Main Street Rule 10b5-1 Stock Purchase Plan”) that Main Street intends to enter into in connection with the Fund Rule 10b5-1 Stock Repurchase Plan. The purchases of any shares pursuant to the Main Street Rule 10b5-1 Stock Purchase Plan will be implemented in accordance with Rule 10b5-1 and Rule 10b-18 under the Exchange Act. The terms and conditions of the Fund Rule 10b5-1 Stock Repurchase Plan and of the Main Street Rule 10b5-1 Purchase Plan will be substantially similar. Subject to the limitations under Rule 10b-18 under the Exchange Act and market conditions, the Fund expects that the aggregate amount of shares (i) repurchased under the Fund Rule 10b5-1 Stock Repurchase Plan and (ii) purchased under the Main Street Rule 10b5-1 Purchase Plan on any single trading day will be split among the Fund and Main Street on a pro rata basis (or as close thereto as reasonably possible) based upon the proportion of the aggregate $40.0 million repurchase/purchase commitment represented by the respective share repurchase/purchase program. There is no assurance that the Fund will repurchase or Main Street will purchase any shares of the Fund’s common stock at any specific discount levels or in any specific amounts under the Fund Rule 10b5-1 Stock Repurchase Plan or the Main Street Rule 10b5-1 Purchase Plan, as applicable. There is also no assurance that the market price of the Fund’s shares of common stock, either absolutely or relative to net asset value per share, will increase as a result of any share repurchases/ purchases, or that the Fund Rule 10b5-1 Stock Repurchase Plan or the Main Street Rule 10b5-1 Purchase Plan will enhance stockholder value over the long term.

6 Investment Portfolio Information as of June 30, 2026(5) The following table provides a summary of the investments in the Fund’s private loan portfolio and LMM portfolio as of June 30, 2026: June 30, 2026 Private Loan LMM (a) (dollars in millions) Number of portfolio companies 81 55 Fair value $ 848.5 $ 503.9 Cost $ 856.3 $ 397.6 Debt investments as a % of portfolio (at cost) 92.9% 71.1% Equity investments as a % of portfolio (at cost) 7.1% 28.9% % of debt investments at cost secured by first priority lien 99.5% 99.9% Weighted-average annual effective yield (b) 10.4% 12.7% Average EBITDA (c) $ 32.9 $ 13.1 (a)The Fund had equity ownership in all of its LMM portfolio companies, and the Fund’s average fully diluted equity ownership in those portfolio companies was 8%. (b)The weighted-average annual effective yields were computed using the effective interest rates for all debt investments as of June 30, 2026, including amortization of deferred debt origination fees and accretion of original issue discount but excluding fees payable upon repayment of the debt investments and any debt investments on non-accrual status, and are weighted based upon the principal amount of each applicable debt investment as of June 30, 2026. (c)The average EBITDA (Earnings Before Interest, Taxes, Depreciation and Amortization) is calculated using a weighted-average for the private loan portfolio companies and a simple average for the LMM portfolio companies. These calculations exclude certain portfolio companies, including three private loan portfolio companies and four LMM portfolio companies, as EBITDA is not a meaningful valuation metric for the Fund’s investments in these portfolio companies, and those portfolio companies whose primary operations have ceased and only residual value remains. The Fund’s total investment portfolio at fair value consists of approximately 61% private loan, 36% LMM, 2% middle market and 1% other portfolio investments. The fair value of the Fund’s LMM portfolio company equity investments was 202% of the related cost basis of such equity investments, and the Fund’s LMM portfolio companies had a median net senior debt (senior interest-bearing debt through the Fund’s debt position less cash and cash equivalents) to EBITDA ratio of 2.7 to 1.0 and a median total EBITDA to senior interest expense ratio of 3.0 to 1.0. Including all debt that is junior in priority to the Fund’s debt position, these median ratios were 2.7 to 1.0 and 2.9 to 1.0, respectively.(5)(6) As of June 30, 2026, the Fund’s investment portfolio also included: • Middle market portfolio investments in eight portfolio companies, collectively totaling $21.9 million in fair value and $40.8 million in cost basis, which comprised 1.6% and 3.1% of the Fund’s investment portfolio at fair value and cost, respectively; and • Other portfolio investments in seven entities, spread across four investment managers, collectively totaling $15.2 million in fair value and $13.2 million in cost basis, which comprised 1.1% and 1.0% of the Fund’s investment portfolio at fair value and cost, respectively.

12 MSC INCOME FUND, INC.Endnotes (1) ANII is NII as determined in accordance with U.S. Generally Accepted Accounting Principles, or U.S. GAAP, excluding the impact of the capital gains incentive fee(3). MSC Income believes presenting ANII and the related per share amount is useful and appropriate supplemental disclosure for analyzing the Fund’s financial performance since the calculation of the capital gains incentive fee is based on realized gains and losses and unrealized fair value appreciation and depreciation, none of which are included in NII. However, ANII is a non-U.S. GAAP measure and should not be considered as a replacement for NII or other earnings measures presented in accordance with U.S. GAAP and should be reviewed only in connection with such U.S. GAAP measures in analyzing MSC Income’s financial performance. A reconciliation of NII in accordance with U.S. GAAP to ANII is detailed in the financial tables included with this press release. (2) ANII before taxes is NII as determined in accordance with U.S. GAAP, excluding the impact of any tax expenses included in NII and the capital gains incentive fee(3). MSC Income believes presenting ANII before taxes and the related per share amount is useful and appropriate supplemental disclosure for analyzing the Fund’s financial performance since (i) the calculation of the capital gains incentive fee is based on realized gains and losses and unrealized fair value appreciation and depreciation, none of which are included in NII, and (ii) tax expenses included in NII may include (a) excise tax expense, which is not solely attributable to NII, and (b) deferred taxes, which are not payable in the current period. However, ANII before taxes is a non-U.S. GAAP measure and should not be considered as a replacement for NII, NII before taxes or other earnings measures presented in accordance with U.S. GAAP and should be reviewed only in connection with such U.S. GAAP measures in analyzing MSC Income’s financial performance. A reconciliation of NII in accordance with U.S. GAAP to ANII before taxes is detailed in the financial tables included with this press release. (3) Pursuant to the Fund’s amended advisory agreement, the incentive fee on capital gains is determined and payable to the Adviser in arrears, if any, as of the end of each calendar year. This fee equals (a) 17.5% of the Fund’s incentive fee capital gain, which is calculated as the Fund’s (i) cumulative net realized gains (net of any related net income tax expense), minus (ii) cumulative unrealized depreciation (net of any related income tax benefit, and excluding any unrealized appreciation), minus (b) the aggregate amount of any previously paid capital gains incentive fee, in each case from the MSC Income Listing date through the applicable calendar year ended. In accordance with U.S. GAAP, at the end of each reporting period, the Fund estimates the capital gains incentive fee and adjusts the accrual for the fee based upon a hypothetical liquidation of its investment portfolio at the then current fair value. Therefore, the calculation of the accrual equals (a) 17.5% of the Fund’s cumulative change in net fair value, including both (i) the cumulative net realized gain/loss and (ii) the cumulative net unrealized appreciation/depreciation (in both cases, net of any related cumulative net income tax expense or benefit), minus (b) the aggregate amount of any previously paid capital gains incentive fee, in each case from the date of the listing of the Fund’s common stock on the New York Stock Exchange on January 29, 2025 through the applicable period ended. However, any capital gains incentive fee accrued related to the unrealized appreciation is neither earned nor payable to the Adviser until such time that it is realized, and assuming at the end of a calendar year such incentive fee capital gain exists excluding any cumulative unrealized appreciation (in each case, net of any related net income tax expense or benefits). If the calculation results in an increase in the accrual compared to the previous quarter, the Fund records an increase to the capital gains incentive fee accrual. If the calculation results in a decrease to the estimated incentive fee on capital gains when compared to the previous quarter, the accrual for the incentive fee on capital gains is reduced to the extent of such decrease. For the second quarter of 2026, the Fund increased the accrual on the capital gains incentive fee by $2.9 million. For further discussion, see Note I — Related Party Transactions and Arrangements in the notes to the consolidated financial statements included in Item 1. Consolidated Financial Statements and Supplementary Data of the Fund’s Quarterly Report on Form 10-Q to be filed with the SEC on August 7, 2026.
