Non-GAAP Financial Measures

This release includes Adjusted EBITDA, Adjusted Free Cash Flow, Net Debt and Adjusted Net Income measures. Each of the metrics are “non-GAAP financial measures” as defined in Regulation G of the Securities Exchange Act of 1934.

Adjusted EBITDA is a supplemental non-GAAP financial measure that is used by management and external users of our financial statements, such as industry analysts, investors, lenders and rating agencies. Adjusted EBITDA is not a measure of net earnings or cash flows as determined by GAAP. We define Adjusted EBITDA as net earnings (loss) before interest, taxes, depreciation and amortization, further adjusted for (i) goodwill and/or long-lived asset impairment charges, (ii) stock-based compensation expense, (iii) restructuring charges, (iv) transaction and integration costs related to acquisitions and (v) other expenses or charges to exclude certain items that we believe are not reflective of ongoing performance of our business.

We believe Adjusted EBITDA is useful because it allows us to supplement the GAAP measures in order to more effectively evaluate our operating performance and compare the results of our operations from period to period without regard to our financing methods or capital structure. We exclude the items listed above in arriving at Adjusted EBITDA because these amounts can vary substantially from company to company within our industry depending upon accounting methods and book values of assets, capital structures and the method by which the assets were acquired. Adjusted EBITDA should not be considered as an alternative to, or more meaningful than, net income as determined in accordance with GAAP, or as an indicator of our operating performance or liquidity. Certain items excluded from Adjusted EBITDA are significant components in understanding and assessing a company’s financial performance, such as a company’s cost of capital and tax structure, as well as the historic costs of depreciable assets, none of which are components of Adjusted EBITDA. Our computations of Adjusted EBITDA may not be comparable to other similarly titled measures of other companies.

Adjusted Free Cash Flow is a supplemental non-GAAP financial measure, and we define Adjusted Free Cash Flow as Adjusted EBITDA less Gross Capital Expenditures. We use Adjusted Free Cash Flow as a financial performance measure used for planning, forecasting, and evaluating our performance. We believe that Adjusted Free Cash Flow is useful to enable investors and others to perform comparisons of current and historical performance of the Company. As a performance measure, rather than a liquidity measure, the most closely comparable GAAP measure is net income (loss).

Net Debt is a supplemental non-GAAP financial measure, and we define Net Debt as total debt less cash and cash equivalents. We use Net Debt to determine our outstanding debt obligations that would not be readily satisfied by our cash and cash equivalents on hand. We believe this metric is useful to analysts and investors in determining our leverage position since we have the ability to, and may decide to, use a portion of our cash and cash equivalents to reduce debt.

We define Adjusted Net Income (Loss) as consolidated net income (loss) adjusted for (i) goodwill and/or long-lived asset impairment charges, (ii) restructuring charges, (iii) transaction and integration costs related to acquisitions, (iv) income taxes expense which is calculated by applying our effective tax rate on unadjusted net income to adjusted pre-tax income, and (v) other expenses or charges to exclude certain items that we believe are not reflective of the ongoing performance of our business. We believe Adjusted Net Income (Loss) is useful because it allows us to exclude non-recurring items in evaluating our operating performance.

We define Adjusted Diluted Earnings (Loss) per share as the quotient of adjusted net income (loss) and diluted weighted average common shares. We believe that Adjusted Diluted Earnings (Loss) per share provides useful information to investors because it allows us to exclude non-recurring items in evaluating our operating performance on a diluted per share basis.
