FORWARD LOOKING STATEMENT Use of Segment Information and Non-GAAP Measures 1) The Company often provides financial metrics for each of Triangle’s three segments of operation. Revenues for each segment are disclosed in notes to the financial statements contained in the Company’s Form 10-K and Form 10-Q filings, but the sum of those unconsolidated revenues differs from Triangle’s consolidated revenues for the corresponding reporting period. Triangle’s consolidated revenues would reflect segment revenues reduced for intracompany sales (i.e. for RockPile services to Triangle’s E&P segment). Triangle also believes that unconsolidated segment revenue assists investors in measuring RockPile’s performance as a stand-alone company without eliminating, on a consolidated basis, certain revenues attributable to completion services for Triangle’s economic interests in new wells operated by Triangle. 2) EBITDA represents income before interest expense, income taxes, depreciation and amortization. EBITDA is not a calculation based upon generally accepted accounting principles in the U.S. ("GAAP"). Triangle has presented ranges of anticipated EBITDA, by segment, because it regularly reviews EBITDA by segment as a measure of the segment’s operating performance. Triangle also believes EBITDA assists investors in comparing segment performance on a consistent basis without regard to interest expense, income taxes, depreciation and amortization, which can vary significantly depending upon many factors. Most of Triangle’s consolidated interest expense relates to debt of the consolidated parent. The total of EBITDA by segment is not indicative of Triangle’s consolidated EBITDA, which reflects other matters such as (i) additional parent administrative costs, (ii) the aforementioned intracompany eliminations, and (iii) the use of the equity method, rather than consolidation, for Triangle’s investment in Caliber. The EBITDA measures presented in the Tables may not always be comparable to similarly titled measures reported by other companies due to differences in the components of the calculation.
