Operational Update

·                  E&P current production of approximately 4,300 Boepd net produced volumes based on a 21-day average

·                  Targeting $10.0 - $10.5 million AFE costs in McKenzie County before any realized benefit from RockPile or Caliber

Reconciliation of Segment Net Income (Loss) to adjusted-EBITDA

*E&P Adj.-EBITDA does not include TPC (parent company) cash G&A expense of $1.3 million

·                  E&P stand-alone adjusted-EBITDA(1)(2)

·                  RPES stand-alone adjusted-EBITDA(1)(2)

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 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 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.
