SAFE HARBOR PROVISIONS FOR FORWARD-LOOKING STATEMENTS

This news release may contain forward-looking statements within the meaning of the federal securities laws, including but not limited to, statements regarding future events, developments in the healthcare sector and regulatory framework, 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, net income, and earnings per share). Risks and uncertainties exist that may cause the results to differ materially from those set forth in these forward-looking statements. Factors that could cause the anticipated results to differ from those described in the forward-looking statements and additional risks and uncertainties are set forth in Part I, Item A of our most recent Annual Report on Form 10-K and subsequently filed Quarterly Reports on Form 10-Q, including but not limited to: 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; impact of incentive payments under The American Recovery and Reinvestment Act on sales and the ability of the Company to meet continued certification requirements; uncertainties related to the future impact of U.S. tax reform; the impact of governmental and regulatory agency investigations; 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; changes of accounting estimates and assumptions used to prepare the prior periods' financial statements; disruptions caused by acquisitions of companies, products, or technologies; and general economic conditions. A significant portion of the Company's quarterly sales of software product licenses and computer hardware is concluded in the last month of a 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. These forward-looking statements speak only as of the date hereof. The Company undertakes no obligation to publicly update any forward-looking statements, whether as a result of new information, future events or otherwise.

USE OF NON-GAAP FINANCIAL MEASURES

This news release contains certain non-GAAP (Generally Accepted Accounting Principles) financial measures, which are provided only as supplemental information. Investors should consider these non-GAAP financial measures only in conjunction with the comparable GAAP financial measures. These non-GAAP measures are not in accordance with or a substitute for U.S. GAAP. Pursuant to the requirements of Regulation G, the Company has provided a reconciliation of non-GAAP financial measures to the most directly comparable financial measure in the accompanying financial tables. Other companies may calculate non-GAAP measures differently than Quality Systems, which limits comparability between companies. The Company believes that its presentation of non-GAAP diluted earnings per share provides useful supplemental information to investors and management regarding the Company's financial condition and results. The presentation of non-GAAP financial information is not intended to be considered in isolation or as a substitute for, or superior to, financial information prepared and presented in accordance with GAAP. The Company calculates non-GAAP diluted earnings per share by excluding net acquisition costs, amortization of acquired intangible assets, amortization of deferred debt issuance costs, restructuring costs, net securities litigation defense costs, share-based compensation, and other non-run-rate expenses from GAAP income before provision for income taxes. The Company utilizes a normalized non-GAAP tax rate to provide better consistency across the interim reporting periods within a given fiscal year by eliminating the effects of non-recurring and period-specific items, which can vary in size and frequency, and which are not necessarily reflective of the Company’s longer-term operations.

The normalized non-GAAP tax rate applied to each quarter of fiscal year 2017 and each quarter of fiscal 2018 through December 31, 2017 is 30.5%. The determination of this rate is based on the consideration of both historic and projected financial results. The Company has not adjusted its non-GAAP tax rate for the three and nine months ended December 31, 2017 following the enactment of the new tax reform legislation on December 22, 2017. We have not yet fully assessed the impact of the tax reform legislation on the fiscal 2018 non-GAAP tax rate and may adjust it in the fiscal 2018 fourth quarter as additional information becomes available and further analysis is completed based on the expected long-term impact of the tax reform legislation in conjunction with any other significant events occur that may materially affect this rate, such as merger and acquisition activity, changes in business outlook, or other changes in expectations regarding tax regulations.

The Company’s future period guidance in this release includes adjustments for items not indicative of the Company’s core operations. Such adjustments are generally expected to be of a nature similar to those adjustments applied to the Company’s historic GAAP financial results in the determination of the Company’s non-GAAP diluted earnings per share. Such adjustments, however, may be affected by changes in ongoing assumptions and judgments as to the items that are excluded in the calculation of non-GAAP adjusted net income and adjusted diluted earnings per share, as described in this release. The exact amount and probable significance of these adjustments, including net acquisition costs, net securities litigation defense costs, and other non-run-rate expenses, are not currently determinable without unreasonable efforts, but may be significant. These items cannot be reliably quantified or forecasted due to the combination of their historic and expected variability. It is therefore not practicable to reconcile this non-GAAP guidance to the most comparable GAAP measures.
