In addition to the regular monthly dividends for the second quarter of 2023, the Board of Directors declared a supplemental cash dividend of $0.175 per share payable in March 2023. 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 December 31, 2022.

Including all dividends declared to date, including the second quarter 2023 regular monthly dividend and the March 2023 supplemental dividend, Main Street will have paid $36.645 per share in cumulative cash dividends since its October 2007 initial public offering at $15.00 per share.

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 2023 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, American Stock Transfer and Trust Company, 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).
