HOUSTON, November 4, 2025 – Main Street Capital Corporation (NYSE: MAIN) (“Main Street”) is

pleased to announce that its Board of Directors declared regular monthly cash dividends of $0.26 per

share for each of January, February and March 2026. These monthly dividends, which will be payable

pursuant to the table below, total $0.78 per share for the first quarter of 2026 and represent a 2.0%

increase from the regular monthly dividends declared for the fourth quarter of 2025 and a 4.0%

increase from the regular monthly dividends paid in the first quarter of 2025. Since its October 2007

initial public offering, Main Street has periodically increased the amount of its regular monthly

dividends paid per share and has never reduced its regular monthly dividend amount per share.

Summary of First Quarter 2026 Regular Monthly Dividends

Declared	Ex-Dividend Date	Record Date	Payment Date	Amount Per Share
11/3/2025	1/8/2026	1/8/2026	1/15/2026	$0.26

In addition to the regular monthly dividends for the first quarter of 2026, the Board of Directors

declared a supplemental cash dividend of $0.30 per share payable in December 2025. This

supplemental cash dividend, which will be payable as set forth in the table below, will be paid out of

Main Street’s undistributed taxable income (taxable income in excess of dividends paid) as of

September 30, 2025.

Supplemental Cash Dividend Payable in December 2025

Declared	Ex-Dividend Date	Record Date	Payment Date	Amount Per Share
11/3/2025	12/22/2025	12/22/2025	12/29/2025	$0.30

Including all dividends declared to date, including the first quarter 2026 regular monthly dividends and

the December 2025 supplemental dividend, Main Street will have paid $47.935 per share in

cumulative cash dividends since its October 2007 initial public offering at $15.00 per share. Including

the first quarter 2026 regular monthly dividends and the December 2025 supplemental dividend, these

most recent dividend declarations represent total dividends to Main Street shareholders of $1.08 per

share, representing an annualized current yield of 7.6% based on the closing price of $57.16 per share

on November 3, 2025.

The final determination of the tax attributes for dividends each year are made after the close of the tax

year. The final tax attributes for 2025 and 2026 dividends are currently expected to include a

combination of ordinary taxable income and qualified dividends and may include capital gains and

return of capital.

Main Street maintains a dividend reinvestment and direct stock purchase plan (the “Plan”). The

dividend reinvestment feature of the Plan (the “DRIP”) provides for the reinvestment of dividends on

behalf of Main Street’s registered stockholders who hold their shares with Main Street’s transfer agent

and registrar, Equiniti Trust Company, LLC, or certain brokerage firms that have elected to participate

in the DRIP. Under the DRIP, if Main Street declares a dividend, registered stockholders who have not

“opted out” of the DRIP by the dividend record date will have their dividend automatically reinvested

into additional shares of Main Street common stock. The direct stock purchase feature of the Plan (the

“DSPP”) provides investors with a convenient and economical method to purchase shares of Main

Street common stock. More information about the Plan (including the DSPP prospectus) can be found

on the Main Street website (https://ir.mainstcapital.com/dividend-reinvestment-and-direct-stock-

purchase-plan).
