Main Street Announces Preliminary Estimate of Fourth Quarter 2024 Operating
Results
Announces Federal Tax Treatment of 2024 Dividends
Announces Fourth Quarter and Full Year 2024 Earnings Release and Conference Call
Schedule
HOUSTON January 16, 2025 – Main Street Capital Corporation (NYSE: MAIN) (“Main Street” or the
“Company”) is pleased to announce its preliminary operating results for the fourth quarter of 2024, the
federal tax treatment of its dividends paid in 2024 and its fourth quarter and full year 2024 earnings release
and conference call schedule.
In commenting on the Company’s preliminary operating results for the fourth quarter of 2024, Dwayne L.
Hyzak, Main Street’s Chief Executive Officer, stated, “We are extremely pleased with our continued strong
performance in the fourth quarter, which closed another record year for Main Street across several key
financial metrics. Our preliminary operating results highlight that our fourth quarter performance resulted in
another quarter of strong operating results, including favorable distributable net investment income per
share and significant net realized gains and net unrealized appreciation, which resulted in an estimated
record return on equity of over 25% for the fourth quarter. We are extremely pleased with our fourth quarter
and full year 2024 results and look forward to sharing the full details of our results in a few weeks.”
Preliminary Estimates of Fourth Quarter 2024 Results
Main Street’s preliminary estimate of fourth quarter 2024 net investment income (“NII”) is $1.01 to $1.03
per share and distributable net investment income (“DNII”) is $1.07 to $1.09 per share.(1)
Main Street’s preliminary estimate of net asset value (“NAV”) per share as of December 31, 2024 is $31.62
to $31.68, representing an increase of $1.05 to $1.11 per share, or 3.4% to 3.6%, from the NAV per share of
$30.57 as of September 30, 2024, with this increase after the impact of the supplemental dividend paid in
December 2024 of $0.30 per share. The estimated increase in NAV per share is primarily due to the net fair
value increase on the investment portfolio resulting from the net unrealized appreciation and the net realized
gain on portfolio investments, including an increase in the fair value of the wholly-owned asset manager, the
accretive impact of equity issuances during the quarter and the net tax benefit for the quarter.
As a result of Main Street’s preliminary estimates of NII, net changes in the fair market value of its
investment portfolio and the net tax benefit as noted above, Main Street estimates that it generated a
quarterly annualized return on equity of over 25% for the fourth quarter of 2024(2) and actual return on
equity of over 19% for the full year.(2)
Main Street preliminarily estimates that investments on non-accrual status comprised 0.9% of the total
investment portfolio at fair value and 3.5% at cost as of December 31, 2024.
Investment Portfolio Activity
The Company’s fourth quarter 2024 operating activities include the following investment activity in the
lower middle market (LMM), private loan and middle market investment strategies:
$167.6 million in total LMM portfolio investments, which after aggregate repayments of debt
investments, return of invested equity capital and a decrease in cost basis due to realized losses
resulted in a net increase of $11.4 million in the total cost basis of the LMM investment portfolio;
$108.0 million in total private loan portfolio investments, which after aggregate repayments of  debt
investments and a decrease in cost basis due to a realized loss resulted in a net increase of $6.7
million in the total cost basis of the private loan investment portfolio; and
a net decrease of $25.2 million in the total cost basis of the middle market investment portfolio.
Federal Tax Treatment of 2024 Dividends
Main Street has posted information regarding the U.S. federal income tax characteristics of its dividends
paid in 2024 on its website under “2024 Form 1099 Information” (https://www.mainstcapital.com/investors/
listed-securities-information/tax-information).(3) Main Street paid dividends totaling $4.11 per share in 2024,
with approximately 31% of such dividends taxed as qualified dividends and approximately 69% taxed as
ordinary income. Qualified dividends paid to non-corporate taxpayers (including individuals) qualify for
favorable tax treatment under the Internal Revenue Code (“IRC”) and, for 2024, will generally be subject to
a maximum 20% U.S. federal income tax rate (plus a 3.8% Medicare surtax, if applicable).
Federal Tax Treatment of 2024 Dividends – Non-U.S. Shareholders
Non-U.S. resident and foreign corporation shareholders (“Non-U.S. Shareholders”) in a Regulated
Investment Company (“RIC”), such as Main Street, are exempt from U.S. withholding tax on both “interest-
related” dividends and short-term capital gains in accordance with the IRC Sections 871(k) and 881(e). In
addition, Non-U.S. Shareholders in a RIC are also exempt from U.S. withholding tax on long-term capital
gains. Main Street paid dividends totaling $4.11 per share in 2024, with approximately 36% of such
dividends relating to “interest-related” dividends and short-term capital gains. See the “Tax Treatment of
2024 Dividends for Non-U.S. Shareholders” posted on Main Street’s website for more details (https://
www.mainstcapital.com/investors/listed-securities-information/tax-information).(3)
To the extent Non-U.S. Shareholder taxes were withheld on dividends distributed, this information may be
considered in connection with any claims for refund on taxes made with the U.S. Internal Revenue Service.
Non-U.S. Shareholders should contact their tax advisor with any questions regarding this information.

End Notes
(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, which includes both share-based compensation expenses and
deferred compensation expense or benefit. Main Street believes presenting distributable net
investment income per share is useful and appropriate supplemental disclosure for analyzing its
financial performance, since share-based compensation does not require settlement in cash and
deferred compensation expense or benefit does 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 and other earnings
measures presented in accordance with U.S. GAAP. Instead, distributable net investment income
should be reviewed only in connection with such U.S. GAAP measures in analyzing Main
Street’s financial performance. In order to reconcile estimated distributable net investment
income per share to estimated net investment income per share in accordance with U.S. GAAP
for the fourth quarter of 2024, an estimated $0.05 to $0.06 per share of non-cash compensation
expenses are added back to calculate estimated distributable net investment income per share.
(2)Return on equity equals the net increase in net assets resulting from operations divided by the
average quarterly total net assets.
(3)No information contained on the Company’s website or disclosed on the February 28, 2025
conference call, including the webcast and the archived versions, is incorporated by reference in
this press release or any of the Company’s filings with the SEC, and you should not consider that
information to be part of this press release or any other such filing.
