Slide 14 — Antero Resources Non-GAAP Measures

Antero Resources Non-GAAP Measures 14 14 14 Antero Resources (NYSE: AR) Adjusted EBITDAX: Adjusted EBITDAX as defined by the Company represents income or loss, including noncontrolling interests, before interest expense, interest income, unrealized gains or losses from commodity derivatives, but including net cash receipts or payments on derivative instruments included in derivative gains or losses other than proceeds from derivative monetizations, amortization of deferred revenue, VPP, income taxes, impairment of property and equipment, depletion, depreciation, amortization, and accretion, exploration expense, equity-based compensation expense, contract termination, loss contingency, transaction fees, gain or loss on sale of assets, loss on convertible note inducement, equity in earnings of and dividends from unconsolidated affiliates and Martica-related adjustments. The GAAP financial measure nearest to Adjusted EBITDAX is net income or loss including noncontrolling interest that will be reported in Antero’s condensed consolidated financial statements. While there are limitations associated with the use of Adjusted EBITDAX described below, management believes that this measure is useful to an investor in evaluating the Company’s financial performance because it: • is widely used by investors in the oil and natural gas industry to measure operating performance without regard to items excluded from the calculation of such term, which may vary substantially from company to company depending upon accounting methods and the book value of assets, capital structure, and the method by which assets were acquired, among other factors; • helps investors to more meaningfully evaluate and compare the results of Antero’s operations from period to period by removing the effect of its capital and legal structure from its consolidated operating structure; and • is used by management for various purposes, including as a measure of Antero’s operating performance, in presentations to the Company’s board of directors, and as a basis for strategic planning and forecasting. Adjusted EBITDAX is also used by the board of directors as a performance measure in determining executive compensation. There are significant limitations to using Adjusted EBITDAX as a measure of performance, including the inability to analyze the effects of certain recurring and non-recurring items that materially affect the Company’s net income or loss, the lack of comparability of results of operations of different companies, and the different methods of calculating Adjusted EBITDAX reported by different companies. In addition, Adjusted EBITDAX provides no information regarding a company’s capital structure, borrowings, interest costs, capital expenditures, and working capital movement or tax position. Adjusted Free Cash Flow: Adjusted Free Cash Flow is a measure of financial performance not calculated under GAAP and should not be considered in isolation or as a substitute for cash flow from operating, investing, or financing activities, as an indicator of cash flow, or as a measure of liquidity. The Company defines Adjusted Free Cash Flow as Net Cash Provided by Operating Activities, less Net Cash Used in Investing Activities, which includes drilling and completion capital and leasehold capital, plus payments for derivative monetizations, less proceeds from asset sales and less distributions to non-controlling interests in Martica, plus transaction expenses. Adjusted Free Cash Flow is a useful indicator of the Company’s ability to internally fund its activities and to service or incur additional debt and estimate return of capital. There are significant limitations to using Adjusted Free Cash Flow as a measure of performance, including the inability to analyze the effect of certain recurring and non-recurring items that materially affect the Company’s net income, the lack of comparability of results of operations of different companies and the different methods of calculating Adjusted Free Cash Flow reported by different companies. Adjusted Free Cash Flow does not represent funds available for discretionary use because those funds may be required for debt service, land acquisitions and lease renewals, other capital expenditures, working capital, income taxes, exploration expenses, and other commitments and obligations.
