Important Disclosure Regarding Non-GAAP Measures EBITDA and Adjusted EBITDA are not measures calculated in accordance with GAAP. EBITDA and Adjusted EBITDA are supplemental non-GAAP financial measures that are used by management and external users of our consolidated financial statements, such as industry analysts, investors, lenders and rating agencies. We define EBITDA as net income excluding net interest expense, income tax and depreciation and amortization. We define Adjusted EBITDA as EBITDA excluding (gain) loss on debt extinguishment and stock-based compensation. Our management believes EBITDA and Adjusted EBITDA are useful, because they allow management to more effectively evaluate our operating performance and compare the results of our operations from period to period without regard to financing methods or capital structure, or other items that impact comparability of financial results from period to period. EBITDA and Adjusted EBITDA should not be considered as alternatives to, or more meaningful than, net income or any other measure as determined in accordance with GAAP. Our computations of EBITDA and Adjusted EBITDA may not be comparable to other similarly titled measures of other companies. We present EBITDA and Adjusted EBITDA, because we believe they provide useful information regarding the factors and trends affecting our business. 21
