QUALITY SYSTEMS, INC. REPORTS RECORD FISCAL 2011 FOURTH QUARTER AND
YEAR-END RESULTS

Strong Quarterly and Year-end Results Reflect Onset of Stimulus Incentives

     IRVINE, Calif. ... May 26, 2011 ... Quality Systems, Inc. (NASDAQ:QSII) announced today results for its fiscal 2011 fourth quarter and year ended March 31, 2011.

     The Company reported record net revenues of $97.1 million for the fiscal 2011 fourth quarter, up 24 percent from the $78.5 million reported in the comparable period a year ago. For the 2011 fourth quarter, net income reached $18.6 million, an increase of 42 percent when compared with net income of $13.1 million for the same period last year. Fully diluted earnings per share were $0.64 in the fiscal 2011 fourth quarter, a 42 percent increase, versus $0.45 fully diluted earnings per share for the fiscal 2010 fourth quarter.

     Revenue for the fiscal year ended March 31, 2011 reached $353.4 million, rising 21 percent when compared with fiscal 2010 revenue of $291.8 million. Net income for fiscal year 2011 was $61.6 million, an increase of 27 percent versus net income of $48.4 million for the 2010 fiscal year. Fully diluted earnings per share increased to $2.12 for fiscal year 2011, up from $1.68 earned during fiscal year 2010, an increase of 26 percent.

     The record fourth quarter and year end results were positively impacted by the onset of the stimulus plan.

     “The last quarter of our fiscal year marked the first full quarter under the stimulus plan of The American Recovery and Reinvestment Act (ARRA). As we have stated, we spent much time preparing all facets of our organization for this important point in time. As we enter the front-end of the stimulus — where regulations are finalized, meaningful use standards have been established and our products certified — the rubber is hitting the road as it relates to benefitting from the stimulus,” explained Steven T. Plochocki, Quality Systems’ chief executive officer.

     “Decisions are being made with more clarity and certainty in a timely manner, which is obviously reflected in our results and will bode well for us over the next few years of the stimulus.

SAFE HARBOR PROVISIONS FOR FORWARD-LOOKING STATEMENTS

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. Among the important factors that could cause actual results to differ materially from those indicated by such forward-looking statements are: the volume and timing of systemssales 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; impact of incentive payments under The American Recovery and Reinvestment Act on sales and the ability of the Company to meet continued certification requirements; 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 upgradereleases; 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.
