HOUSTON, Nov. 3, 2026 /PRNewswire/ — Main Street Capital Corporation (NYSE: MAIN) (“Main Street”) is pleased to announce that its Board of Directors declared regular monthly cash dividends of $0.27 per share for each of January, February and March 2027. These monthly dividends, which will be payable pursuant to the table below, total $0.81 per share for the first quarter of 2027 and represent a 1.9% increase from the regular monthly dividends declared for the fourth quarter of 2026 and a 3.8% increase from the regular monthly dividends paid in the first quarter of 2026. 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.

In addition to the regular monthly dividends for the first quarter of 2027, the Board of Directors declared a supplemental cash dividend of $0.30 per share payable in December 2026. 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, 2026.

Including all dividends declared to date, including the first quarter 2027 regular monthly dividends and the December 2026 supplemental dividend, Main Street will have paid $52.315 per share in cumulative cash dividends since its October 2007 initial public offering at $15.00 per share. Including the first quarter 2027 regular monthly dividends and the December 2026 supplemental dividend, these most recent dividend declarations represent total dividends to Main Street shareholders of $1.11 per share, representing an annualized current yield of 7.9% based on the closing price of $56.30 per share on November 2, 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 and 2027 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).
