QUALITY SYSTEMS REPORTS RECORD FISCAL 2011 THIRD QUARTER RESULTS;
INCREASES QUARTERLY DIVIDEND

Company Well Positioned as First Year of Stimulus Incentives Kick in

     IRVINE, Calif. ... January 28, 2011 ... Quality Systems, Inc. (NASDAQ:QSII) announced today the results of operations for its fiscal 2011 third quarter ended December 31, 2010.

     The Company reported record net revenues of $91.9 million for the fiscal 2011 third quarter, an increase of 23 percent from the $75.0 million reported in the same period a year ago. The Company reported net income of $17.5 million, up 33 percent versus net income of $13.2 million for the comparable period last year. Fully diluted earnings per share were $0.60 in the fiscal 2011 third quarter; rising 33 percent when compared with $0.46 fully diluted earnings per share for the third quarter of fiscal 2010.

     Quality Systems, Inc. also announced that the Company’s Board of Directors increased the cash dividend by five cents ($0.05), or 17 percent, to Thirty-Five Cents ($0.35) per share on the Company’s outstanding shares of Common Stock, payable to shareholders of record as of March 17, 2011, with an anticipated distribution date of April 5, 2011. The $0.35 per share cash dividend is pursuant to the Company’s current policy to pay a regular quarterly dividend on the Company’s outstanding shares of Common Stock, subject to further Board review and approval, and establishment of record and distribution dates by the Board prior to the declaration and payment of each such quarterly dividend.

     “We are very pleased with the Company’s third quarter performance. Our entire organization has worked very hard preparing for the first year of incentives provided under The American Recovery and Reinvestment Act (ARRA). The team is ready to witness the fruits of their labor,” noted Steven T. Plochocki, Quality Systems’ chief executive officer.

     “As we said for the past 22 months since the bill was first introduced, there were levels of uncertainty and speculation, but once certification was announced in October 2010 and the regulations for Stage 1 Meaningful Use were finalized, the path became very clear. We are in a very positive position to take advantage of the benefits stemming from the first year of the stimulus incentives. Additionally, the Board’s declaration to increase our quarterly dividend is indicative of the Company’s strength in the marketplace and optimism about the future. We remain very encouraged by the industry opportunity before us, and confident in the certified electronic health solutions we bring to the physician, dental and hospital marketplaces,” Plochocki concluded.

This news release may contain forward-looking statements within the meaning of the federal securities laws. Statements regarding future events, developments, the Company’s future performance, as well as management’s expectations, beliefs, intentions, plans, estimates or projections relating to the future (including, without limitation, statements concerning revenue and net income), are forward-looking statements within the meaning of these laws and involve a number of risks and uncertainties. Management believes that these forward looking statements are reasonable and are based on reasonable assumptions and forecasts, however, undue reliance should not be placed on such statements that speak only as of the date hereof. Moreover, these forward-looking statements are subject to a number of risks and uncertainties, some of which are outlined below. As a result, actual results may vary materially from those anticipated by the forward-looking statements.

sales and installations; length of sales cycles and the installation process; the possibility that products will not achieve or sustain market acceptance; seasonal patterns of sales and customer buying behavior; the development by competitors of new or superior technologies; the timing, cost and success or failure of new product and service introductions, development and product upgrade releases; undetected errors or bugs in software; product liability; changing economic, political or regulatory influences in the health-care industry; changes in product-pricing policies; availability of third-party products and components; competitive pressures including product offerings, pricing and promotional activities; the Company’s ability or inability to attract and retain qualified personnel; possible regulation of the Company’s software by the U.S. Food and Drug Administration; uncertainties concerning threatened, pending and new litigation against the Company including related professional services fees; uncertainties concerning the amount and timing of professional fees incurred by the Company generally; changes of accounting estimates and assumptions used to prepare the prior periods’ financial statements; general economic conditions; and the risk factors detailed from time to time in the Company’s periodic reports and registration statements filed with the Securities and Exchange Commission.

A significant portion of the Company’s quarterly sales of software product licenses and computer hardware is concluded in the last month of the fiscal quarter, generally with a concentration of such revenues earned in the final ten business days of that month. Due to these and other factors, the Company’s revenues and operating results are very difficult to forecast. A major portion of the Company’s costs and expenses, such as personnel and facilities, are of a fixed nature and, accordingly, a shortfall or decline in quarterly and/or annual revenues typically results in lower profitability or losses. As a result, comparison of the Company’s period-to-period financial performance is not necessarily meaningful and should not be relied upon as an indicator of future performance. The Company undertakes no obligation to publicly update any forward-looking statements, whether as a result of new information, future events or otherwise.
