Adjusted EBITDA is presented in this Press Release because SemGroup believes it provides additional information with respect to its financial performance and its ability to meet future debt service, capital expenditures and working capital requirements. Adjusted EBITDA represents earnings before interest, taxes, depreciation and amortization, adjusted for selected items that SemGroup believes impact the comparability of financial results between reporting periods. Although SemGroup presents selected items that it considers in evaluating its performance, you should also be aware that the items presented do not represent all items that affect comparability between the periods presented. Variations in SemGroup's operating results are also caused by changes in volumes, prices, exchange rates, mechanical interruptions and numerous other factors. These types of variances are not separately identified in this Press Release. Because all companies do not use identical calculations, SemGroup's presentation of Adjusted EBITDA may be different from similarly titled measures of other companies. Reconciliations of net income (loss) to Adjusted EBITDA for the periods presented are included in the tables at the end of this Press Release.
