Non–GAAP Reconciliation and Measures The Company presents the net present value (denoted “NPV” or “NPV10” in the presentation) of our reserves attributable to our Engineered and Contingent Locations as of December 30, 2016, which is equal to the present value, discounted at 10% per annum, of the estimated fair value of future cash flows of our these net of capital and operating costs, before deducting future income taxes. The Company has used a specified price deck and reserve classifications as described in this presentation. These assumptions do not coincide with SEC pricing or reserve classification guidelines. The Company does not believe NPV to be a “Non-GAAP financial measure,” as defined in SEC rules, since GAAP does not provide for disclosure of the Standardized Measure as of an interim date or when using non-SEC guided assumptions and the Company believes there is no directly comparable GAAP measure; therefore it is not practicable to provide a reconciliation to any GAAP measure. The Company uses NPV as an arbitrary reserve asset value measure to compare against past reserve bases and the reserve bases of other business entities. NPV should not be considered as an estimate of fair market value or as an alternative to PV-10 or Standardized Measure. The Company’s calculations of NPV are based on numerous assumptions that may change as a result of future activities or circumstances. EBITDA is defined by the Company as net income (loss) PLUS: (1) interest expense, including net losses (gains) on interest rate derivative contracts; (2) net losses (gains) on commodity derivatives; (3) net settlements received (paid) on commodity derivatives; (4) depletion, depreciation, amortization, and accretion; (5) stock-based compensation expense; (6) acquisition costs included general and administrative; (7) income tax expense (benefit); (8) loss (gain) on sale of oil and natural gas properties; (9) impairment of oil and natural gas properties; and (10) other non-recurring items that we deem appropriate; LESS: (1) premiums on commodity derivative contracts; (2) interest income; and (3) other non-recurring items that we deem appropriate. Adjusted EBITDA is used as a supplemental financial measure by our management and by external users of our financial statements, such as investors, commercial banks and others, to assess our operating performance as compared to that of other companies in our industry, without regard to financing methods, capital structure, or historical cost basis. It is also used to assess our ability to incur and service debt and fund capital expenditures. Our Adjusted EBITDA should not be considered an alternative to net income (loss), operating income (loss), cash flow provided by or used in operating activities or any other measure of financial performance or liquidity presented in accordance with GAAP. Our Adjusted EBITDA may not be comparable to similarly titled measures of another company because all companies may not calculate Adjusted EBITDA in the same manner. This presentation contains disclosure of free cash flow, which is a “non-GAAP financial measure,” as defined in SEC rules. Free cash flow is presented herein because of the wide acceptance of such measure by the investment community as financial indicators of a company’s ability to internally fund exploration and development activities. We also view the non-GAAP measure of free cash flow as a useful tool for comparisons of our financial indicators with those of peer companies that follow the full cost method of accounting. Free cash flow should not be considered as an alternative to net income or other cash flow presentations, as defined by GAAP. We have not included in this presentation forward-looking cash flows from operating activities because such information is not accessible on a forward-looking basis without an unreasonable effort. We are unable to provide a reconciliation of the forward-looking non-GAAP financial measure, free cash flow, to the most directly comparable GAAP financial measure, cash flows from operating activities, because the information necessary for a quantitative reconciliation of the forward-looking non-GAAP financial measure to the most directly comparable GAAP financial measure is not available to us without unreasonable efforts. The probable significance of providing this forward-looking non-GAAP financial measure without the directly comparable GAAP financial measure is that such GAAP financial measure may be materially different from the corresponding non-GAAP financial measure. This presentation contains disclosure of cash production expense, which is a “non-GAAP financial measure,” as defined in SEC rules. Cash production expense equals production expense minus non-cash production expenses. Cash production expense is presented herein in an attempt to assist the public in understanding the difference between production expense as will be reported in SEC filed financials. We also view the non-GAAP measure of cash production expense as a useful tool for comparisons of our financial indicators with those of peer companies. Cash production expense should not be considered as an alternative to production expense presentations, as defined by GAAP. This presentation contains disclosure of cash G&A per Boe, which is a “non -GAAP financial measure,” as defined in SEC rules. Cash G&A expense equals G&A excluding certain non-recurring acquisition and divestiture expenses and stock based compensation. Cash G&A is reported herein because this measure is commonly used by management, analysts and investors as an indicator of cost management and operating efficiency on a comparable basis from period to period. In addition, management believes cash G&A per Boe is used by analysts and others in valuation, comparison and investment recommendations of companies in the oil and gas industry to allow for analysis of G&A spend without regard to stock-based compensation programs which can vary substantially from company to company. Cash G&A per Boe should not be considered as an alternative to, or more meaningful than, total G&A per Boe as determined in accordance with U.S. GAAP and may not be comparable to other similar titled measures of other companies. We have not included in this presentation forward-looking G&A per Boe because such information is not accessible on a forward-looking basis without an unreasonable effort. We are unable to provide a reconciliation of the forward-looking non-GAAP financial measure, cash G&A per Boe, to the most directly comparable GAAP financial measure, G&A per Boe, because the information necessary for a quantitative reconciliation of the forward-looking non-GAAP financial measure to the most directly comparable GAAP financial measure is not available to us without unreasonable efforts. The probable significance of providing this forward-looking non-GAAP financial measure without the directly comparable GAAP financial measure is that such GAAP financial measure may be materially different from the corresponding non-GAAP financial measure. 46 © 2017 Sanchez Energy Corporation Explanation of Non-GAAP Measures Disclosure of Net Present Value (“NPV”)
