NON-GAAP FINANCIAL MEASURES

We believe that disclosing adjusted diluted earnings per share, which is diluted earnings per share excluding the impact from restructuring expenses, acquisition-related expenses and the acquisition inventory fair value adjustment is useful to investors as a measure of operating performance. We use this as one measure to monitor and evaluate operating performance. Adjusted diluted earnings per share is a financial measure that does not reflect United States Generally Accepted Accounting Principles (GAAP). We calculate this measure by adding back the after-tax effect of the restructuring expenses, acquisition-related expenses and the acquisition inventory fair value adjustment to net income and dividing the result by the diluted weighted average shares outstanding.

We believe that disclosing earnings before interest, taxes, depreciation and amortization (EBITDA), EBITDA excluding the impact from stock-based compensation, restructuring expenses, acquisition-related expenses and the acquisition inventory fair value adjustment (Adjusted EBITDA) and Adjusted EBITDA divided by revenue (Adjusted EBITDA margin) are useful to investors as a measure of leverage and operating performance. We use these measures to monitor and evaluate leverage and operating performance. EBITDA, Adjusted EBITDA and Adjusted EBITDA margin are financial measures that do not reflect GAAP. We calculate EBITDA by adding back interest, taxes, depreciation and amortization expense to net income. Adjusted EBITDA is calculated by adding back stock-based compensation, restructuring expenses, acquisition-related expenses and the acquisition inventory fair value adjustment to EBITDA. Adjusted EBITDA margin is calculated by dividing Adjusted EBITDA by revenue.

We believe that disclosing free cash flow is useful to investors as a measure of operating performance. We use this measure as an indicator of our strength and ability to generate cash. Free cash flow is a financial measure that does not reflect GAAP. We calculate free cash flow as net cash provided by (used in) operating activities less purchases of property and equipment and businesses, net of cash acquired, plus cash proceeds from sales of property and equipment.

Investors should consider these non-GAAP financial measures in addition to, not as a substitute for or better than, financial measures prepared in accordance with GAAP. Reconciliations of the components of these measures to the most directly comparable GAAP financial measures are included in Exhibits B, C, D, E, F and G of this earnings release.
