Main Street Paying an Aggregate of $0.355 per Share in Regular Monthly and Supplemental Semi-Annual Cash Dividends in July 2013

HOUSTON, June 27, 2013 /PRNewswire/ -- As previously announced on May 13, 2013, Main Street Capital Corporation (NYSE: MAIN) ("Main Street") will pay a special, or supplemental semi-annual, cash dividend of $0.20 per share in July 2013, which is in addition to Main Street's regular monthly dividends of $0.155 per share to be paid in each of July, August and September 2013.  The purpose of this press release is to serve as a reminder with respect to the July 2013 dividend activity and related dates and to avoid potential confusion related thereto.

Main Street's July and August regular monthly and supplemental semi-annual cash dividends will be payable as set forth below to stockholders who hold such shares through the trading day immediately preceding the respective ex-dividend date. 

The July 2013 supplemental semi-annual dividend will be paid out of Main Street's undistributed taxable income (or "spillover income"), or taxable net income in excess of dividends paid, as of June 30, 2013.  As previously discussed in the May 13, 2013 press release, which can be found on Main Street's website at www.mainstcapital.com, Main Street estimates that the supplemental semi-annual dividend represents a payout of approximately one-sixth of Main Street's estimated spillover income as of March 31, 2013.

Based on the regular monthly dividends declared for the third quarter of 2013 and the $0.20 per share supplemental semi-annual cash dividend payable in July 2013, Main Street will have paid $9.96 per share in cumulative dividends since its October 2007 initial public offering. The combination of the current regular monthly dividend rate of $0.155 per share and the current supplemental semi-annual dividend rate of $0.20 per share  equate to annualized cash dividends of $2.26 per share, or an annualized yield of 8.4% based on Main Street's current share price.
