Announces Third Quarter 2025 Earnings Release and Conference Call Schedule

HOUSTON, Oct. 14, 2025 /PRNewswire/ -- Main Street Capital Corporation (NYSE: MAIN) ("Main Street" or the "Company") is pleased to announce its preliminary operating results for the third quarter of 2025 and its third quarter 2025 earnings release and conference call schedule.

In commenting on the Company's preliminary operating results for the third quarter of 2025, Dwayne L. Hyzak, Main Street's Chief Executive Officer, stated, "We are pleased with our performance in the third quarter, which resulted in another quarter of strong operating results, including favorable distributable net investment income per share and a new record for net asset value per share for the thirteenth consecutive quarter, primarily driven by a significant net fair value increase of our existing lower middle market investment portfolio. Our third quarter results continued our positive performance over the last few years and resulted in an estimated return on equity of over 16% for the quarter. We look forward to sharing the full details of our results in a few weeks."

Preliminary Estimates of Third Quarter 2025 Results

Main Street's preliminary estimate of third quarter 2025 net investment income ("NII") is $0.95 to $0.99 per share, distributable net investment income ("DNII")⁽¹⁾ is $1.01 to $1.05 per share and DNII before taxes⁽²⁾ is $1.05 to $1.09 per share.

Main Street's preliminary estimate of net asset value ("NAV") per share as of September 30, 2025 is $32.74 to $32.82, representing an increase of $0.44 to $0.52 per share, or 1.3% to 1.6%, from the NAV per share of $32.30 as of June 30, 2025, with this increase after the impact of the supplemental dividend paid in September 2025 of $0.30 per share. The estimated NAV per share increase is primarily due to the net fair value increase of the existing investment portfolio and the accretive impact of equity issuances, partially offset by the net tax provision for the quarter. The net fair value increase of the existing investment portfolio is the result of net fair value increases of the existing lower middle market ("LMM") and private loan investment portfolios, partially offset by net fair value decreases of the wholly-owned asset manager and the middle market investment portfolio.

As a result of Main Street's preliminary estimates of NII, the net changes in the fair value of its investment portfolio and the net tax provision as noted above, Main Street estimates that it generated a quarterly annualized return on equity of over 16% for the third quarter of 2025.⁽³⁾

Main Street preliminarily estimates that investments on non-accrual status comprised 1.2% of the total investment portfolio at fair value and 3.6% at cost as of September 30, 2025.

Investment Portfolio Activity

The Company's third quarter 2025 operating activities include the following investment activity in the LMM and private loan investment strategies:

• $106.2 million in total LMM portfolio investments, which after aggregate repayments, return of invested equity capital and a decrease in cost basis due to realized losses on LMM portfolio investments resulted in a net increase of $61.3 million in the total cost basis of the LMM investment portfolio; and
• $113.3 million in total private loan portfolio investments, which after aggregate repayments and a decrease in cost basis due to realized losses on private loan portfolio investments resulted in a net decrease of $68.8 million in the total cost basis of the private loan investment portfolio.

Endnotes

(1)	DNII is NII 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 DNII 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, DNII is a non-U.S. GAAP measure and should not be considered as a replacement for NII and other earnings measures presented in accordance with U.S. GAAP. Instead, DNII should be reviewed only in connection with such U.S. GAAP measures in analyzing Main Street's financial performance. In order to reconcile estimated DNII per share to estimated NII per share in accordance with U.S. GAAP for the third quarter of 2025, an estimated $0.06 to $0.07 per share of non-cash compensation expenses are added back to estimated NII to calculate estimated DNII per share.
(2)	DNII before taxes is NII before taxes as determined in accordance with 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 DNII before taxes 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, and since tax expenses may include excise tax expense, which is not solely attributable to NII, and deferred taxes, which are not payable in the current period. However, DNII before taxes is a non-U.S. GAAP measure and should not be considered as a replacement for NII, NII before taxes and other earnings measures presented in accordance with U.S. GAAP. Instead, DNII before taxes should be reviewed only in connection with such U.S. GAAP measures in analyzing Main Street's financial performance. In order to reconcile estimated DNII before taxes per share to estimated NII per share in accordance with U.S. GAAP for the third quarter of 2025, an estimated $0.06 to $0.07 per share of non-cash compensation expenses and an estimated $0.03 to $0.04 per share of NII related tax expenses are added back to estimated NII to calculate estimated DNII before taxes per share.
(3)	Return on equity equals the net increase in net assets resulting from operations divided by the average quarterly total net assets.
(4)	No information contained on the Company's website or disclosed on the November 7, 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.
