NEW YORK, Nov. 20, 2013 /PRNewswire/ -- Pomerantz Grossman Hufford Dahlstrom & Gross LLP is investigating claims on behalf of investors of Quality Systems, Inc. ("Quality Systems" or the "Company") (NASDAQ: QSII).  Such investors are advised to contact Lesley F. Portnoy at lfportnoy@pomlaw.com or 888-476-6529, ext. 223.

The investigation concerns whether Quality Systems and certain of its officers and/or directors have violated Sections 10(b) and 20(a) of the Securities Exchange Act of 1934

On July 26, 2012, a mere three days after the Company affirmed its prior guidance, the Company suddenly announced that its earnings per share had precipitously declined and, as a result, it was retracting its guidance. Quality Systems disclosed that, compared to the year-ago quarter, its net income had declined 18% and its EPS had declined 19%, and thus, it was "not affirming our previous guidance nor providing revised guidance."

On this news, shares of Quality Systems fell from $23.36 per share to $15.95 per share, or 33%, on July 26, 2012.
