Main Street Announces Preliminary Estimate of Second Quarter 2026

Operating Results

Announces Second Quarter 2026 Earnings Release and Conference Call Schedule

HOUSTON – July 16, 2026 – Main Street Capital Corporation (NYSE: MAIN) (“Main Street”

or the “Company”) is pleased to announce its preliminary operating results for the second quarter

of 2026 and its second quarter 2026 earnings release and conference call schedule.

In commenting on the Company’s preliminary operating results for the second quarter of 2026,

Dwayne L. Hyzak, Main Street’s Chief Executive Officer, stated, “We are very pleased with our

performance in the second quarter, which resulted in another strong quarter of operating results,

including favorable distributable net investment income before taxes and an increase to our net

asset value per share for the sixteenth consecutive quarter. The increase in net asset value per

share was primarily driven by significant net fair value appreciation on our lower middle market

and private loan investment portfolios, including the benefit of another material realized gain in

our lower middle market portfolio. Our strong second quarter results are highlighted by a

favorable estimated return on equity of over 18% for the quarter. We look forward to sharing the

full details of our second quarter 2026 results in a few weeks.”

Preliminary Estimates of Second Quarter 2026 Results

Main Street’s preliminary estimate of second quarter 2026 net investment income (“NII”) is

$0.95 to $0.99 per share, distributable net investment income (“DNII”)(1) is $1.02 to $1.06 per

share and DNII before taxes(2) is $1.06 to $1.10 per share.

Main Street’s preliminary estimate of net asset value (“NAV”) per share as of June 30, 2026 is

$33.88 to $33.96, representing an increase of $0.42 to $0.50 per share, or 1.2% to 1.5%, from the

NAV per share of $33.46 as of March 31, 2026, with this increase after the impact of the

supplemental dividend paid in June 2026 of $0.30 per share. The estimated NAV per share

increase is primarily due to the net fair value appreciation on the investment portfolio and the

accretive impact of equity issuances, partially offset by a decrease due to the issuance of

restricted stock, the total dividends per share paid in the second quarter in excess of NII per share

and the net tax provision. The net fair value appreciation on the investment portfolio is primarily

the result of net fair value appreciation on the lower middle market (“LMM”) investment

portfolio, private loan investment portfolio and other portfolio investments, partially offset by

fair value depreciation of the wholly-owned external investment manager.

As a result of Main Street’s preliminary estimates of NII, net fair value appreciation and the net

tax provision as noted above, Main Street estimates that it generated an annualized return on

equity of over 18% for the second quarter.(3)

Main Street preliminarily estimates that investments on non-accrual status comprised 1.1% of the

total investment portfolio at fair value and 4.0% at cost as of June 30, 2026.

Investment Portfolio Activity

The Company’s second quarter 2026 operating activities include the following investment

activity in the LMM and private loan investment strategies:

•$95.7 million in total LMM portfolio investments, which after aggregate repayments and

return of invested equity capital resulted in a net decrease of $30.6 million in the total

cost basis of the LMM investment portfolio; and

•$238.9 million in total private loan portfolio investments, which after aggregate

repayments, return of invested equity capital and a decrease in cost basis due to a realized

loss resulted in a net increase of $60.2 million in the total cost basis of the private loan

investment portfolio.

Second Quarter 2026 Earnings Release and Conference Call Schedule

Main Street will release its second quarter 2026 results on Thursday, August 6, 2026, after the

financial markets close. In conjunction with the release, Main Street has scheduled a conference

call, which will be broadcast live via phone and over the Internet, on Friday, August 7, 2026, at
