The following table provides a summary of the Fund's operating results for the third quarter of 2026:

	Three Months Ended September 30,

	(dollars in thousands, except per share amounts)

Return on equity - quarter annualized (3)	9.7 %	14.6 %	(4.9) %	(34) %

The $0.2 million increase in total investment income in the third quarter of 2026 from the comparable period of the prior year was principally attributable to (i) a $0.2 million increase in dividend income, primarily due to a $1.0 million increase in dividend income from the Fund's private loan portfolio companies, partially offset by a $0.8 million decrease in dividend income from the Fund's LMM portfolio companies and (ii) a $0.1 million increase in interest income, primarily due to higher average levels of income producing investment portfolio debt investments, partially offset by the negative impact from investment portfolio debt investments on non-accrual status and a decrease in interest rates, primarily resulting from decreases in benchmark index rates on floating rate investment portfolio debt investments. These increases were partially offset by a $0.1 million decrease in fee income. The $0.2 million increase in total investment income in the third quarter of 2026 includes the impact of an increase of $0.9 million in certain income considered less consistent or non-recurring, primarily related to increases of (i) $0.7 million in such dividend income and (ii) $0.3 million in such interest income from accelerated prepayment, repricing and other activity related to certain investment portfolio debt investments, in each case when compared to the same period in 2025.

Total expenses, net of waivers, increased by $1.8 million, or 9.6%, to $20.1 million in the third quarter of 2026 from $18.3 million for the same period in 2025. This increase was principally attributable to (i) a $1.3 million increase in interest expense, (ii) a $0.9 million increase in the ending accrual for the accrued capital gains incentive fee(4) as of September 30, 2026 and (iii) a $0.5 million increase in base management fee, partially offset by a $0.8 million decrease in incentive fee on income, net of waivers. 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 as a result of the issuance of the May 2029 Notes in the first quarter of 2026 and the issuance of the September 2029 Notes in the third 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 the capital gains incentive fee accrual(4) was due to the net fair value appreciation of the Fund's investments in the third quarter of 2026. The increase in base management fee was the result of the Fund's increased average total assets. The decrease in incentive fee on income, net of waivers, was the result of (i) a $0.5 million increase in the voluntary waiver of incentive fee on income by the Adviser (defined below) and (ii) a $0.4 million decrease in the gross calculated incentive fee on income, primarily driven by a decrease in pre-incentive fee NII.

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 third quarter of 2026, a decrease from 2.0% for the third quarter of 2025.

NII related federal and state income and other tax expenses increased $0.4 million and excise tax expense increased $0.2 million in the third quarter of 2026 when compared to the same period in 2025, resulting in an increase in tax expenses included in NII of $0.6 million. The increase in NII related federal and state income and other tax expenses was due to an increase in taxable NII between the comparable periods and the increase in excise tax expense was due to an increase in undistributed taxable income as of September 30, 2026.

The $2.2 million decrease in NII in the third quarter of 2026 from the comparable period of the prior year was principally attributable to (i) the increase in total expenses, net of waivers, (which includes the capital gains incentive fee accrual(4)) and (ii) the increase in NII related tax expenses, partially offset by an increase in total investment income, each as discussed above. NII on a per share basis decreased by $0.03 per share for the third quarter of 2026 as compared to the third quarter of 2025, to $0.32 per share, reflecting the impact of the $0.02 per share capital gains incentive fee accrual(4) in the third quarter of 2026.

The $1.3 million, or $0.01 per share, decrease in ANII(1) in the third quarter of 2026 to $15.3 million, or $0.34 per share, from $16.6 million, or $0.35 per share, in the third quarter of 2025 was principally attributable to the same factors noted above for the change in NII, but excluding the impact of the $0.9 million, or $0.02 per share, increase in the capital gains incentive fee accrual.(4)

The per share changes in NII and ANII(1) in the third quarter of 2026 from the comparable period of the prior year include the impact of a 4.2% 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 third quarter of 2026 each include an increase of $0.02 per share resulting from an increase in investment income considered less consistent or non-recurring in nature compared to the third quarter of 2025, as discussed above.

The $18.1 million net increase in net assets resulting from operations in the third quarter of 2026 represents an $8.4 million decrease from the third quarter of 2025. This decrease was primarily the result of (i) a $6.0 million lower net fair value increase of the Fund's portfolio investments resulting from the net impact of net realized gains/losses and net unrealized appreciation/depreciation, with the lower increase resulting from a net fair value increase of $5.2 million in the third quarter of 2026 compared to a net fair value increase of $11.2 million in the comparable period of the prior year, (ii) a $2.2 million decrease in NII as discussed above and (iii) a $0.2 million increase in the net tax provision on the net fair value change of the portfolio investments, resulting from a net tax provision of $1.4 million in the third quarter of 2026 compared to a net tax provision of $1.2 million in the comparable period of the prior year. The $5.2 million net fair value increase in the third quarter of 2026 was the result of net unrealized appreciation (including the reversal of net unrealized depreciation recognized in prior periods due to the net realized loss in the quarter) of $9.0 million, partially offset by a net realized loss of $3.9 million. The $11.2 million net fair value increase in the third quarter of 2025 was the result of net unrealized appreciation of $21.0 million, partially offset by a net realized loss of $9.9 million. The $3.9 million net realized loss from investments for the third quarter of 2026 was primarily the result of (i) a $9.4 million realized loss on the restructure of a private loan investment, (ii) a $6.4 million realized loss on the full exit of a LMM portfolio investment, (iii) a $0.5 million realized loss on the partial exit of a private loan portfolio investment and (iv) a $0.4 million realized loss on the full exit of a middle market investment, partially offset by (i) an $11.0 million realized gain on the full exit of a private loan investment, (ii) a $0.7 million realized gain on the partial exit of an other portfolio investment and (iii) a $0.6 million realized gain on a distribution from a private loan portfolio investment.

The following table provides a summary of the total net unrealized appreciation of $9.0 million for the third quarter of 2026:

	Three Months Ended September 30, 2026
	Private Loan	LMM (a)	Middle Market	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	$ (2.5)	$ 6.1	$ 0.4	$ (0.7)	$ 3.3
Net unrealized appreciation (depreciation) relating to portfolio investments	4.1	2.5	(0.6)	(0.3)	5.7
Total net unrealized appreciation (depreciation) relating to portfolio investments	$ 1.6	$ 8.6	$ (0.2)	$ (1.0)	$ 9.0

(a) Includes unrealized appreciation on 25 LMM portfolio investments and unrealized depreciation on 18 LMM portfolio investments.

Investment Portfolio Information as of September 30, 2026(5)

The following table provides a summary of the investments in the Fund's private loan portfolio and LMM portfolio as of September 30, 2026:

	September 30, 2026
	Private Loan	LMM (a)
	(dollars in millions)
Number of portfolio companies	81	53
Fair value	$ 843.8	$ 503.0
Cost	$ 849.6	$ 388.1
Debt investments as a % of portfolio (at cost)	90.5 %	72.5 %
Equity investments as a % of portfolio (at cost)	9.5 %	27.5 %
% of debt investments at cost secured by first priority lien	99.5 %	99.9 %
Weighted-average annual effective yield (b)	10.5 %	12.7 %
Average EBITDA (c)	$ 36.3	$ 13.5

(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 September 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 September 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 three LMM portfolio companies, as EBITDA is not a meaningful valuation metric for the Fund's investments in these portfolio companies, and those portfolio companies whose primary operations have ceased and only residual value remains.

The Fund's total investment portfolio at fair value consists of approximately 61.2% private loan, 36.5% LMM, 1.4% middle market and 0.9% other portfolio investments.

The fair value of the Fund's LMM portfolio company equity investments was 218% 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 2.6 to 1.0 and a median total EBITDA to senior interest expense ratio of 2.9 to 1.0. Including all debt that is junior in priority to the Fund's debt position, these median ratios were 2.6 to 1.0 and 2.9 to 1.0, respectively.(5)(6)

As of September 30, 2026, the Fund's investment portfolio also included:

Middle market portfolio investments in seven portfolio companies, collectively totaling $19.8 million in fair value and $38.9 million in cost basis, which comprised 1.4% and 3.0% of the Fund's investment portfolio at fair value and cost, respectively; and
Other portfolio investments in seven entities across four investment managers, collectively totaling $12.2 million in fair value and $11.1 million in cost basis, which comprised 0.9% of the Fund's investment portfolio at both fair value and cost.

As of September 30, 2026, investments on non-accrual status comprised 1.4% of the total investment portfolio at fair value and 5.2% at cost, and the Fund's total portfolio investments at fair value were 107% of the related cost basis.

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(4). 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 the capital gains incentive fee(4) and any tax expenses included in NII. 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)	Return on equity equals the net increase in net assets resulting from operations divided by the average quarterly total net assets.

(4)	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 date of the listing of the Fund's common stock on the New York Stock Exchange on January 29, 2025 (the "MSC Income Listing") 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 MSC Income Listing date through the applicable period ended. However, any capital gains incentive fee accrued related to the unrealized appreciation is neither earned nor payable to the Adviser until such time that it is realized, and assuming at the end of a calendar year such incentive fee capital gain exists excluding any cumulative unrealized appreciation (in each case, net of any related net income tax expense or benefit). 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 third quarter of 2026, the Fund increased the accrual on the capital gains incentive fee by $0.9 million. For further discussion, see Note J — Related Party Transactions and Arrangements in the notes to the consolidated financial statements included in Item 1. Consolidated Financial Statements of the Fund's Quarterly Report on Form 10-Q to be filed with the SEC on November 6, 2026.

(5)	Portfolio company financial information has not been independently verified by MSC Income.

(6)	These credit statistics exclude portfolio companies on non-accrual status and portfolio companies for which EBITDA is not a meaningful metric.
