Graymark Announces 1-for-4 Reverse Stock Split

OKLAHOMA CITY, May 25, 2011 /PRNewswire/ -- Graymark Healthcare, Inc. (NASDAQ: GRMH), the nation's second largest provider of diagnostic sleep services and an innovator in comprehensive care for obstructive sleep apnea (OSA), reported that its Board of Directors approved a 1-for-4 reverse stock split, which will be effective after the close of the market on June 3, 2011.

The 1-for-4 reverse stock split will automatically convert all shares of the company's stock issued and outstanding to one new share of common stock, par value $0.0001 per share. The reverse stock split, which was approved by the company's shareholders on February 1, 2011, will reduce the number of shares of the company's outstanding common stock from approximately 34.1 million, as of the filing date of the company's most recent Quarterly Report on Form 10-Q, to approximately 8.5 million.

No fractional shares will be issued in connection with the reverse stock split. The company will round up to the next whole share in lieu of issuing factional shares that would have been issued in the reverse split. For a 20 trading day period immediately following the reverse split, Graymark's common stock will trade on a post-split basis on the NASDAQ Capital Market under the trading symbol "GRMHD" as an interim symbol to denote the reverse split. After this 20 trading day period, Graymark's common stock will resume trading on the NASDAQ Capital Market under the symbol "GRMH." In addition, the common stock will also trade under a new CUSIP number effective June 6, 2011.
