Main Street Issues Reminder Regarding Upcoming Dividend Activity

HOUSTON, Dec. 6, 2018 /PRNewswire/ -- As previously announced on October 11, 2018, Main Street Capital Corporation (NYSE: MAIN) ("Main Street") will pay a semi-annual supplemental cash dividend of $0.275 per share in December 2018, which is in addition to Main Street's previously announced regular monthly cash dividends of $0.195 per share to be paid in each of December 2018 and January, February and March 2019. Consistent with prior periods with several dividends in close proximity, Main Street is issuing this reminder with respect to its upcoming dividend activity since there are multiple ex-dividend and payment dates in December 2018.

Each of Main Street's December 2018 and January 2019 regular monthly dividends and December 2018 semi-annual supplemental dividend will be payable as set forth below to stockholders who hold shares through the trading day immediately preceding the ex-dividend date for such dividend.

Summary of Upcoming Dividend Activity

Declared	Ex-Dividend Date	Record Date	Payment Date	Amount Per Share
7/31/2018	11/19/2018	11/20/2018	12/14/2018	$0.195
10/10/2018	12/17/2018	12/18/2018	12/27/2018	$0.275
10/30/2018	12/28/2018	12/31/2018	1/15/2019	$0.195
Aggregate total payable in December 2018 and January 2019:				$0.665 (1)


(1)	Additionally, Main Street has previously declared regular monthly dividends of $0.195 per share payable on February 15, 2019 and March 15, 2019 to stockholders of record on January 18, 2019 and February 21, 2019, respectively.

Including all dividends declared to date, Main Street will have paid $24.82 per share in cumulative dividends since its October 2007 initial public offering at $15.00 per share. The combination of the current regular monthly dividend rate of $0.195 per share and the current semi-annual supplemental dividend rate of $0.275 per share equates to annualized cash dividends of $2.89 per share. As previously discussed by Main Street on its third quarter 2018 earnings conference call, it is Main Street's current intention to fully absorb its semi-annual supplemental dividends into its regular monthly dividends, and in the process maintain and grow its total combined dividends, by gradually reducing its semi-annual supplemental dividends while increasing its regular monthly dividends over multiple years beginning in 2019.
