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. 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 systems 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 timing, cost and success or failure of new product
and service introductions, development and product upgrade releases; undetected
errors or bugs in software; 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 Quality Systems' 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.
