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).
