Share-Based Payment Arrangement [Abstract]

Main Street accounts for its share-based compensation plans using the fair value method, as prescribed by ASC 718, Compensation—Stock Compensation. Accordingly, for restricted stock awards (“RSAs”), Main Street measured the grant date fair value based upon the market price of its common stock on the date of the grant and amortizes the fair value of the awards as share-based compensation expense over the requisite service period, which is generally the vesting term.

Main Street’s Board of Directors approves the issuance of shares of restricted stock to Main Street employees pursuant to the Main Street Capital Corporation 2022 Equity and Incentive Plan (the “Equity and Incentive Plan”). These shares generally vest over a three-year period from the grant date. The fair value is expensed over the service period, starting on the grant date. The following table summarizes the restricted stock issuances approved by Main Street’s Board of Directors under the Equity and Incentive Plan, net of shares forfeited, if any, and the remaining shares of restricted stock available for issuance as of December 31, 2022.

As of December 31, 2022, the following table summarizes the restricted stock issued to Main Street’s non-employee directors and the remaining shares of restricted stock available for issuance pursuant to the Main Street Capital Corporation 2022 Non-Employee Director Restricted Stock Plan. These shares are granted upon appointment or election to

the board and vest on the day immediately preceding the annual meeting of stockholders following the respective grant date and are expensed over such service period.
