The $0.9 million increase in total investment income in the first quarter of 2026 from the comparable period of
the prior year was principally attributable to (i) a $2.0 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 (ii) a $0.5 million increase in fee income, primarily due to an increase in fee
income related to increased investment activity. These increases were partially offset by a $1.6 million decrease
in dividend income, primarily due to a $1.5 million decrease in dividend income from the Fund’s LMM
portfolio companies. The $0.9 million increase in total investment income in the first quarter of 2026 is after the
impact of a decrease of $0.2 million in certain income considered less consistent or non-recurring, primarily
related to decreases of (i) $0.2 million in such dividend income and (ii) $0.2 million in such interest income
from accelerated prepayment, repricing and other activity related to certain investment portfolio debt
3
investments, partially offset by a $0.2 million increase in such fee income, in each case when compared to the
same period in 2025.
Total expenses, net of waivers, increased by $0.4 million, or 2.5%, to $16.8 million in the first quarter of 2026
from $16.4 million for the same period in 2025. This increase was principally attributable to (i) a $0.7 million
increase in interest expense, (ii) a $0.3 million increase in base management fees and (iii) a $0.1 million
increase in incentive fee on income, net of waivers, partially offset by a $0.6 million decrease in the ending
accrual for the accrued capital gains incentive fee(3) as of March 31, 2026. The increase in interest expense is
primarily related to an increase in average borrowings outstanding used to fund a portion of the growth of the
Fund’s investment portfolio, partially offset by decreased weighted-average interest rates on the Credit
Facilities due to decreases in benchmark floating index interest rates and a decrease in the applicable interest
rate spread on the SPV Facility resulting from the amendment of the SPV Facility in March 2025 (with the
Credit Facilities and the SPV Facility each defined in the Liquidity and Capital Resources section below). The
increase in base management fees is primarily the result of the Fund’s increased average total assets, partially
offset by the benefit of the lower base management fee percentage for the full quarter in the first quarter of 2026
compared to the benefit for a partial quarter in the first quarter of 2025 as a result of the Fund’s entry into an
amended advisory agreement (the “Amended Advisory Agreement”) with the Adviser (defined below),
effective upon the listing of the Fund’s common stock on the New York Stock Exchange on January 29, 2025
(the “MSC Income Listing”). The increase in incentive fee on income, net of waivers, is the result of (a) an
increase in the gross calculated incentive fee on income of $1.1 million, partially offset by (b) a $1.0 million
voluntary waiver of incentive fee on income by the Adviser. The increase in the gross calculated incentive fee
on income is a result of the Amended Advisory Agreement. The reduction in the capital gains incentive fee
accrual(3) is due to the net fair value depreciation of the Fund’s investments in the first quarter of 2026.
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, decreased to 1.8% on an
annualized basis for the first quarter of 2026, from 1.9% for the first quarter of 2025, primarily due to the
benefit of the lower base management fee percentage in the first quarter of 2026 as discussed above.
The $0.5 million increase in NII in the first quarter of 2026 from the comparable period of the prior year was
principally attributable to an increase in total investment income, partially offset by an increase in total
expenses, net of waivers, each as discussed above. NII on a per share basis was $0.35 per share for the first
quarter of 2026, consistent with the first quarter of 2025.
The $0.1 million, or $0.01 per share, decrease in ANII(1) in the first quarter of 2026 to $15.6 million, or $0.34
per share, from $15.7 million, or $0.35 per share, in the first quarter of 2025 was principally attributable to the
same factors noted above for the change in NII, but excluding the impact of the $0.6 million decrease in the
capital gains incentive fee accrual.
The per share changes in NII and ANII(1) in the first quarter of 2026 from the comparable period of the prior
year include the impact of a 3.2% increase in the weighted-average shares outstanding, primarily due to shares
issued in connection with the MSC Income Listing and shares issued through the dividend reinvestment plan,
partially offset by shares repurchased by the Fund, in each case since the beginning of the comparable period of
the prior year. NII and ANII(1) on a per share basis in the first quarter of 2026 each include a decrease of $0.01
per share resulting from a decrease in investment income considered less consistent or non-recurring in nature
compared to the first quarter of 2025, as discussed above.
The $13.2 million net increase in net assets resulting from operations in the first quarter of 2026 represents a
$2.7 million decrease from the first quarter of 2025. This decrease was primarily the result of (i) a $2.5 million
increase in net tax provision on the net fair value change of the portfolio investments resulting from a net tax
provision of $0.1 million in the first quarter of 2026 compared to a net tax benefit of $2.4 million in the
comparable period of the prior year and (ii) a $0.6 million decrease in the net fair value change of the Fund’s
4
portfolio investments resulting from the net impact of net realized gains/losses and net unrealized appreciation/
depreciation, with the decrease resulting from a net fair value decrease of $2.9 million in the first quarter of
2026 compared to a net fair value decrease of $2.3 million in the comparable period of the prior year, partially
offset by a $0.5 million increase in NII as discussed above. The $2.9 million net fair value decrease in the first
quarter of 2026 was the result of a net realized loss of $0.2 million and net unrealized depreciation (including
the reversal of net fair value depreciation recognized in prior periods due to the net realized loss in the quarter)
of $2.6 million. The $2.3 million net fair value decrease in the first quarter of 2025 was the result of a net
realized loss of $21.1 million, partially offset by net unrealized appreciation of $18.8 million. The $0.2 million
net realized loss from investments for the first quarter of 2026 was primarily the result of $3.7 million of
realized losses on the full exits of two private loan portfolio investments, partially offset by a $3.1 million
realized gain on the full exit of a private loan portfolio investment and a net realized gain on other private loan
portfolio investments.
The following table provides a summary of the total net unrealized depreciation of $2.6 million for the first
quarter of 2026:

(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 March 31, 2026, including amortization of deferred debt origination fees and accretion of
original issue discount but excluding fees payable upon repayment of the debt investments and any debt
investments on non-accrual status, and are weighted based upon the principal amount of each applicable
debt investment as of March 31, 2026.
(c)The average EBITDA (Earnings Before Interest, Taxes, Depreciation and Amortization) is calculated using
a weighted-average for private loan portfolio companies and a simple average for LMM portfolio
companies. These calculations exclude certain portfolio companies, including four private loan portfolio
companies and three LMM portfolio companies, as EBITDA is not a meaningful valuation metric for the
Fund’s investments in these portfolio companies, and those portfolio companies whose primary purpose is
to own real estate and those portfolio companies whose primary operations have ceased and only residual
value remains.
The Fund’s total investment portfolio at fair value consists of approximately 60% private loan, 37% LMM, 2%
middle market and 1% other portfolio investments.
The fair value of the Fund’s LMM portfolio company equity investments was 204% 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 2.5 to
6
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 2.6 to 1.0 and 2.9 to 1.0, respectively.(5)(6)
As of March 31, 2026, the Fund’s investment portfolio also included:
•Middle market portfolio investments in eight portfolio companies, collectively totaling $23.0 million in fair
value and $40.3 million in cost basis, which comprised 1.7% and 3.1% of the Fund’s investment portfolio at
fair value and cost, respectively; and
•Other portfolio investments in seven entities, spread across four investment managers, collectively totaling
$15.6 million in fair value and $13.4 million in cost basis, which comprised 1.1% and 1.0% of the Fund’s
investment portfolio at fair value and cost, respectively.
As of March 31, 2026, investments on non-accrual status comprised 1.1% of the total investment portfolio at
fair value and 4.2% at cost, and the Fund’s total portfolio investments at fair value were 106% of the related
cost basis.

(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 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) the
Fund’s cumulative change in net fair value, including both (i) the cumulative net realized gain/loss and (ii)
the cumulative net unrealized appreciation/depreciation (in both cases, net of any related cumulative net
income tax expense or benefit), minus (b) the aggregate amount of any previously paid capital gains
incentive fee, in each case from the MSC Income Listing date through the applicable period ended.
However, any capital gains incentive fee accrued related to the unrealized appreciation is neither earned nor
payable to the Adviser until such time that it is realized, and assuming at the end of a calendar year such
incentive fee capital gain exists excluding any cumulative unrealized appreciation (in each case, net of any
related net income tax expense or benefits). If the calculation results in an increase in the accrual compared
to the previous quarter, the Fund records an increase to the capital gains incentive fee accrual. If the
calculation results in a decrease to the estimated incentive fee on capital gains when compared to the
previous quarter, the accrual for the incentive fee on capital gains is reduced to the extent of such decrease.
For the first quarter of 2026, the Fund reduced the accrual on the capital gains incentive fee by $0.6 million.
