HMS Income Fund Declares 2.25% Special Stock Dividend

HOUSTON – September 13, 2012 – HMS Income Fund, Inc. (“HMS Income Fund”), a business development company sponsored by Hines and sub-advised by Main Street Capital Partners, LLC, a subsidiary of Main Street Capital Corporation (NYSE: MAIN), today declared a special stock dividend of approximately 2.25 shares of HMS Income Fund’s common stock per 100 shares of common stock. The board of directors approved the stock dividend in light of the performance of HMS Income Fund’s portfolio. “The purpose of this special stock dividend was to ensure that HMS Income Fund’s net asset value (“NAV”) per share does not exceed its current offering price, after deduction of selling commissions and dealer manager fees, as required by the Investment Company Act of 1940,” said Ryan Sims, chief financial officer for HMS Income Fund.

Sims also said that the special stock dividend increased the number of shares outstanding as of the issue date, thereby reducing NAV per share, “however, because the stock dividend was issued to all existing stockholders in proportion to their holdings, the reduction in NAV per share as a result of the stock dividend was offset exactly by the increase in the number of shares owned by each investor. As the overall value of an investor’s position is not reduced as a result of the special stock dividend, the board of directors determined that its payment was not dilutive to existing stockholders.” Sims added that the stock dividend it is not expected to represent a taxable dividend because it did not change any stockholder’s proportionate interest in HMS Income Fund.
