•Net decrease of $17.6 million in the total cost basis of the middle market investment portfolio

In commenting on the Company’s operating results for the second quarter of 2025, Dwayne L. Hyzak, Main

Street’s Chief Executive Officer, stated, “We are pleased with our performance in the second quarter, which

resulted in another quarter of strong operating results highlighted by an annualized return on equity of 17.1%,

favorable levels of net investment income per share and distributable net investment income per share and

another record for net asset value per share primarily driven by a significant net fair value increase, which

includes the benefits of the largest realized gain in Main Street’s history. We believe that these continued strong

results demonstrate the sustainable strength of our overall platform, the benefits of our differentiated and

diversified investment strategies, the unique contributions of our asset management business and the continued

underlying strength and quality of our portfolio companies, particularly those in our highly unique lower middle

market investment strategy.”

Mr. Hyzak continued, “Our continued positive performance allowed us to increase the total dividends paid to

our shareholders in the second quarter by 2.9% over the prior year, continuing our trend of increasing the

dividends paid to our shareholders over the past few years, while also continuing to generate distributable net

investment income per share which exceeds the total dividends paid to our shareholders in the second quarter.

Our strong second quarter performance resulted in the declaration of another $0.30 per share supplemental

dividend to be paid in September 2025, representing our sixteenth consecutive quarterly supplemental dividend,

to go with the ten increases to our regular monthly dividends declared since the fourth quarter of 2021. We

remain confident that our diversified lower middle market and private loan investment strategies, together with

the benefits of our asset management business, our cost efficient operating structure and conservative capital

structure, will allow us to continue to deliver superior results for our shareholders.”

Second Quarter 2025 Operating Results

The following table provides a summary of our operating results for the second quarter of 2025:

Three Months Ended June 30,
2025 2024 Change ($) Change (%)
(in thousands, except per share amounts)
Interest income $100,857 $100,031 $826 1%

3

The $11.8 million increase in total investment income in the second quarter of 2025 from the comparable period

of the prior year was principally attributable to (i) an $11.2 million increase in dividend income, primarily due

to an $11.5 million increase in dividend income from our LMM portfolio companies and a $0.6 million increase

in dividend income from our private loan portfolio companies, partially offset by a $0.5 million decrease in

dividend income from our External Investment Manager (as defined in the External Investment Manager

section below) and (ii) a $0.8 million increase in interest income, primarily due to higher average levels of

income producing investment portfolio debt investments, partially offset by an increase in investments on non-

accrual status and a decrease in interest rates on floating rate investment portfolio debt investments, primarily

resulting from decreases in benchmark index rates. The $11.8 million increase in total investment income in the

second quarter of 2025 is after the impact of an increase of $3.0 million in certain income considered less

consistent or non-recurring, primarily related to (i) a $3.0 million increase in such dividend income and (ii) a

$0.7 million increase in such interest income from accelerated prepayment, repricing and other activity related

to certain investment portfolio debt investments, partially offset by a $0.7 million decrease in such fee income,

in each case when compared to the same period in 2024.

Total cash expenses(4) increased $4.6 million, or 11.6%, to $44.5 million in the second quarter of 2025 from

$39.9 million for the same period in 2024. This increase in total cash expenses was principally attributable to (i)

a $3.4 million increase in interest expense, (ii) a $0.7 million increase in cash compensation expenses(4) and (iii)

a $0.5 million increase in general and administrative expense. The increase in interest expense is primarily

related to (i) an increase in average borrowings outstanding used to fund a portion of the growth of our

investment portfolio and (ii) an increased weighted-average interest rate on our debt obligations resulting from

the issuance of the June 2027 Notes (as defined in the Liquidity and Capital Resources section below) and the

repayment of certain notes at maturity in May 2024, partially offset by a decreased weighted-average interest

rate on our Credit Facilities (as defined in the Liquidity and Capital Resources section below) due to decreases

in benchmark index rates and decreases to the applicable margin rates related to the amendments of our Credit

Facilities in April 2025.

Non-cash compensation expenses(4) increased $1.2 million in the second quarter of 2025 from the comparable

period of the prior year, primarily driven by (i) a $0.6 million increase in deferred compensation expense and

(ii) a $0.5 million increase in share-based compensation.

Our Operating Expenses to Assets Ratio (which includes non-cash compensation expenses(4)) on an annualized

basis was 1.4% for the second quarter of 2025, an increase from 1.3% for the second quarter of 2024.

Excise tax expense increased $0.5 million and net investment income related federal and state income and other

tax expenses increased $1.2 million in the second quarter of 2025 compared to the same period in 2024. The

increase in excise tax is due to the increase in undistributed taxable income as of June 30, 2025 and the increase

in net investment income related federal and state income and other tax expenses is due to an increase in taxable

net investment income between the relevant periods.

The $4.3 million increase in net investment income and the $5.5 million increase in distributable net investment

income(1) in the second quarter of 2025 from the comparable period of the prior year were both principally

attributable to the increase in total investment income, partially offset by increased expenses and excise tax and

net investment income related taxes, each as discussed above. Net investment income per share increased by

$0.02 per share and distributable net investment income(1) per share increased by $0.03 per share for the second

quarter of 2025 as compared to the second quarter of 2024, to $0.99 per share and $1.06 per share, respectively.

These increases include the impact of a 3.6% increase in the weighted-average shares outstanding compared to

the second quarter of 2024, primarily due to shares issued since the beginning of the comparable period of the

prior year through our (i) at-the-market (“ATM”) equity issuance program, (ii) dividend reinvestment plan and

(iii) equity incentive plans. Net investment income and distributable net investment income(1) on a per share

basis in the second quarter of 2025 include a net increase of $0.02 per share and $0.03 per share, respectively,

resulting from an increase in investment income and an increase in non-cash deferred compensation expenses,

4

in both cases considered less consistent or non-recurring in nature compared to the second quarter of 2024, as

discussed above.

The $122.5 million net increase in net assets resulting from operations in the second quarter of 2025 represents

a $19.8 million increase from the second quarter of 2024. This increase was primarily the result of (i) a $7.0

million increase in the net fair value change of our 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 $33.5 million in the second quarter of 2025 compared to a net fair value increase of $26.5

million in the prior year, (ii) an $8.6 million benefit from the change in the net tax provision/benefit on the net

fair value change of our portfolio investments resulting from a net tax benefit of $0.9 million in the second

quarter of 2025 compared to a net tax provision of $7.7 million in the prior year and (iii) a $4.3 million increase

in net investment income as discussed above. The $33.5 million net fair value increase in the second quarter of

2025 was the result of a net realized gain of $52.4 million, partially offset by net unrealized depreciation

(including the reversal of net fair value appreciation in prior periods on the net realized gain) of $19.0 million.

The $26.5 million net fair value increase in the second quarter of 2024 was the result of a net realized gain of

$3.4 million and net unrealized appreciation of $23.0 million. The $52.4 million net realized gain from

investments for the second quarter of 2025 was primarily the result of (i) a $55.6 million realized gain on the

full exit of a LMM portfolio investment, (ii) $6.2 million of realized gains on the partial exits of two other

portfolio investments and (iii) a $5.2 million realized gain on the full exit of a private loan portfolio investment,

partially offset by (i) an $8.5 million realized loss on the full exit of a private loan portfolio investment and (ii) a

$6.2 million realized loss on the restructure of a private loan portfolio investment.

The following table provides a summary of the total net unrealized depreciation of $19.0 million for the second

quarter of 2025:

Three Months Ended June 30, 2025
LMM (a) Private<br><br>Loan Middle<br><br>Market Other Total

LMM portfolio investments.

Investment Portfolio Information as of June 30, 2025(5)

The following table provides a summary of the investments in our LMM portfolio and private loan portfolio as

of June 30, 2025:

As of June 30, 2025
LMM (a) Private Loan
(dollars in millions)
Number of portfolio companies 88 87
Fair value $2,668.8 $1,920.3
Cost $2,105.0 $1,958.0
Debt investments as a % of portfolio (at cost) 70.1% 94.7%
Equity investments as a % of portfolio (at cost) 29.9% 5.3%
% of debt investments at cost secured by first priority lien 99.3% 99.9%
Weighted-average annual effective yield (b) 12.8% 11.4%
Average EBITDA (c) $10.4 $32.5

___________________________

(a)We had equity ownership in all of our LMM portfolio companies, and our average fully diluted equity

ownership in those portfolio companies was 38%.

6

(b)The weighted-average annual effective yields were computed using the effective interest rates for all debt

investments as of June 30, 2025, 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 June 30, 2025.

(c)The average EBITDA (Earnings Before Interest, Taxes, Depreciation and Amortization) is calculated using

a simple average for the LMM portfolio and a weighted-average for the private loan portfolio. These

calculations exclude certain portfolio companies, including six LMM portfolio companies and six private

loan portfolio companies, as EBITDA is not a meaningful valuation metric for our 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 fair value of our LMM portfolio company equity investments was 197% of the cost of such equity

investments, and our LMM portfolio companies had a median net senior debt (senior interest-bearing debt

through our 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 2.9 to 1.0. Including all debt that is junior in priority to our debt

position, these median ratios were 2.7 to 1.0 and 2.8 to 1.0, respectively.(5)(6)

As of June 30, 2025, our investment portfolio also included:

•Middle market portfolio investments in 12 portfolio companies, collectively totaling $108.7 million in fair

value and $134.2 million in cost basis, which comprised 2.1% and 3.1% of our investment portfolio,

respectively;

•Other portfolio investments in 32 entities, spread across 12 investment managers, collectively totaling

$122.7 million in fair value and $126.0 million in cost basis, which comprised 2.4% and 2.9% of our

investment portfolio at fair value and cost, respectively; and

•Our investment in the External Investment Manager, with a fair value of $272.6 million and a cost basis of

$29.5 million, which comprised 5.4% and 0.7% of our investment portfolio at fair value and cost,

respectively.

As of June 30, 2025, investments on non-accrual status comprised 2.1% of the total investment portfolio at fair

value and 5.0% at cost, and our total portfolio investments at fair value were 117% of the related cost basis.

External Investment Manager

MSC Adviser I, LLC is our wholly-owned portfolio company and registered investment adviser that provides

investment management services to external parties (the “External Investment Manager”). We share employees

with the External Investment Manager and allocate costs related to such shared employees and other operating

expenses to the External Investment Manager. The total contribution of the External Investment Manager to our

net investment income consists of the combination of the expenses we allocate to the External Investment

Manager and the dividend income we earn from the External Investment Manager. During the second quarter of

2025, the External Investment Manager earned $5.7 million of management fee income, a decrease of $0.2

million from the second quarter of 2024, and incentive fees of $3.7 million, a decrease of $0.4 million from the

second quarter of 2024. In addition, we allocated $5.9 million of total expenses to the External Investment

Manager, consistent with the second quarter of 2024. The combination of the dividend income we earned from

the External Investment Manager and expenses we allocated to it resulted in a total contribution to our net

investment income of $8.7 million, representing a decrease of $0.5 million from the second quarter of 2024.

The External Investment Manager ended the second quarter of 2025 with total assets under management of $1.6

billion.

Endnotes

(1)Distributable net investment income is net investment income as determined in accordance with U.S.

Generally Accepted Accounting Principles, or U.S. GAAP, excluding the impact of non-cash compensation

expenses.(4) Main Street believes presenting distributable net investment income and the related per share

amount is useful and appropriate supplemental disclosure for analyzing its financial performance since non-

cash compensation expenses(4) do not result in a net cash impact to Main Street upon settlement. However,

distributable net investment income is a non-U.S. GAAP measure and should not be considered as a

replacement for net investment income or other earnings measures presented in accordance with U.S. GAAP

and should be reviewed only in connection with such U.S. GAAP measures in analyzing Main Street’s

financial performance. A reconciliation of net investment income in accordance with U.S. GAAP to

distributable net investment income is detailed in the financial tables included with this press release.

(2)Return on equity equals the net increase in net assets resulting from operations divided by the average

quarterly total net assets.

(3)Net investment income and distributable net investment income for 2024 and the first quarter of 2025

necessary to present the comparable year-to-date amounts for the six months ended June 30, 2025 have been

revised to include the impact of excise tax and net investment income related federal and state income and

other tax expenses previously included within the total income tax provision. This correction was

determined to be immaterial to any impacted prior periods and had no impact on net increases in or net

assets resulting from operations or the related per share amounts.

(4)Non-cash compensation expenses consist of (i) share-based compensation and (ii) deferred compensation

expense or benefit, both of which are non-cash in nature. Share-based compensation does not require

settlement in cash. Deferred compensation expense or benefit does not result in a net cash impact to Main

Street upon settlement. The appreciation (depreciation) in the fair value of deferred compensation plan

assets is reflected in Main Street’s Consolidated Statements of Operations as unrealized appreciation

(depreciation) and an increase (decrease) in compensation expenses, respectively. Cash compensation

expenses are total compensation expenses as determined in accordance with U.S. GAAP, less non-cash

compensation expenses. Total cash expenses are total expenses, as determined in accordance with U.S.

GAAP, excluding non-cash compensation expenses. Main Street believes presenting cash compensation

expenses, non-cash compensation expenses and total cash expenses is useful and appropriate supplemental

disclosure for analyzing its financial performance since non-cash compensation expenses do not result in a

net cash impact to Main Street upon settlement. However, cash compensation expenses, non-cash

compensation expenses and total cash expenses are non-U.S. GAAP measures and should not be considered

as a replacement for compensation expenses, total expenses 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 Main Street’s financial performance. A reconciliation of compensation expenses and total

expenses in accordance with U.S. GAAP to cash compensation expenses, non-cash compensation expenses

and total cash expenses is detailed in the financial tables included with this press release.

(5)Portfolio company financial information has not been independently verified by Main Street.

(6)These credit statistics exclude portfolio companies on non-accrual status and portfolio companies for which

EBITDA is not a meaningful metric.
