Use of Segment Information and Non-GAAP Measures

(1)         Adjusted-EBITDA represents income before interest expense, income taxes, depreciation and amortization, other non-cash items, and non-recurring items. Adjusted-EBITDA is not a calculation based upon generally accepted accounting principles in the U.S. (“GAAP”). Triangle has presented Adjusted-EBITDA by segment because it regularly reviews Adjusted-EBITDA by segment as a measure of the segment’s operating performance. Triangle also believes Adjusted-EBITDA assists investors in comparing segment performance on a consistent basis without regard to interest expense, income taxes, depreciation and amortization, other non-cash items, and non-recurring items 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 Adjusted-EBITDA by segment is not indicative of Triangle’s consolidated Adjusted-EBITDA, which reflects other matters such as (i) additional parent administrative costs, (ii) intracompany eliminations, and (iii) the use of the equity method, rather than consolidation, for Triangle’s investment in Caliber.  The Adjusted-EBITDA measures presented in the “Reconciliation Tables” may not always be comparable to similarly titled measures reported by other companies due to differences in the components of the calculation.

We believe that net income before income taxes is the performance measure calculated and presented in accordance with GAAP that is most directly comparable to Adjusted-EBITDA. Net income before income taxes will be significantly affected by consolidated interest expense and full-cost pool amortization.  Such amortization varies with changes in proved reserves, well costs during the year, and future plans in developing proved undeveloped reserves.

(2)         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 stand-alone 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 RPES services to Triangle’s E&P segment).

Triangle also believes that stand-alone segment revenue assists investors in measuring RPES’s and CLBR’s performance as stand-alone companies without eliminating, on a consolidated basis, certain revenues attributable to completion services for Triangle’s economic interests in new wells operated by Triangle.

(3)         Adjusted net income (loss) is defined as net income (loss) applicable to common stockholders Adjusted to exclude certain charges or amounts in order to provide users of this financial information with additional meaningful comparisons between current results and the results of prior periods. We present this measure because (i) it is consistent with the manner in which the Company’s performance is measured relative to the performance of its peers, (ii) this measure is more comparable to earnings estimates provided by securities analysts, and (iii) charges or amounts excluded cannot be reasonably estimated and guidance provided by the company excludes information regarding these types of items. These Adjusted amounts are not a measure of financial performance under GAAP. We believe that net income (loss) is the performance measure calculated and presented in accordance with GAAP that is most directly comparable to Adjusted net income (loss).
