share for each of July, August and September 2026. These monthly dividends, which will be payable

pursuant to the table below, total $0.795 per share for the third quarter of 2026 and represent a 1.9%

increase from the regular monthly dividends declared for the second quarter of 2026 and a 3.9%

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

and the June 2026 supplemental dividend, Main Street will have paid $50.11 per share in cumulative

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

quarter 2026 regular monthly dividends and the June 2026 supplemental dividend, these most recent

dividend declarations represent total dividends to Main Street shareholders of $1.095 per share,

representing an annualized current yield of 7.9% based on the closing price of $55.76 per share on

May 4, 2026.

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 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).
