Share Repurchase Program

On July 31, 2017, the Board of Directors approved a $50 million share repurchase program, which will primarily be used to offset dilution caused by the issuance and exercise of stock options and other equity compensation. The Company expects to complete this share repurchase program in fiscal 2017.

Important Information Regarding Non-GAAP Financial Measures

The Company presents non-GAAP financial measures, including Adjusted Net Income, Adjusted EBITDA, Adjusted Diluted EPS, Adjusted SG&A, Adjusted Income Taxes, Adjusted Operating Income and Adjusted Gross Profit, in this press release as management uses these measures in assessing our operating performance, and we believe they are helpful to investors, securities analysts and other interested parties, in evaluating the performance of companies in our industry. We also believe that these non-GAAP financial measures are useful to management and investors, securities analysts and other interested parties as measures of our comparative operating performance from period to period. These non-GAAP financial measures are not measurements of financial performance under GAAP. They should not be considered as alternatives to cash flow from operating activities, as measures of liquidity, or as alternatives to net income as a measure of our operating performance or any other measures of performance derived in accordance with GAAP. The methods used by the Company to calculate its non-GAAP financial measures may differ significantly from methods used by other companies to compute similar measures. As a result, any non-GAAP financial measures presented herein may not be comparable to similar measures

provided by other companies. Please see the schedules to this press release for additional information and reconciliations of such non-GAAP financial measures to the nearest GAAP measure. With respect to our expectations under “Full Year 2017 Outlook” above, for Adjusted Diluted EPS a reconciliation to the closest corresponding GAAP financial measure is not available without unreasonable efforts on a forward-looking basis due to the high variability, complexity and low visibility with respect to litigation expenses excluded from this non-GAAP financial measure. We expect the variability of these charges to have a potentially unpredictable, and potentially significant, impact on our future GAAP financial results.
