Legal Disclaimers Forward Looking Statements This presentation contains, and our officers and representatives may from time to time make, “forward-looking statements” within the meaning of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. All statements, other than statements of historical facts, included in this presentation that address activities, events, conditions or developments that Sanchez Energy Corporation (“Sancez Energy”, or the “Company”) expects, estimates, believes or anticipates will or may occur or exist in the future, including, statements related to cash flows, benefits of the joint venture with Targa, benefits of the plant design, the capacity of the plant, access to midstream assets, access to end markets, our strategy and plans, our view of the market and expected cost efficiencies, are forward-looking statements. These statements are based on certain assumptions made by the company based on management’s experience, perception of historical trends and technical analyses, current conditions, anticipated future developments and other factors believed to be appropriate and reasonable by management. When used in this presentation, words such as “will,” “potential,” “believe,” “estimate,” “intend,” “expect,” “may,” “should,” “anticipate,” “c ould,” “plan,” “predict,” “project,” “profile,” “model,” “strategy,” “future” or their negatives or the statements that include these words, are intended to identify forward-looking statements, although not all forward-looking statements contain such identifying words. In particular, statements, express or implied, concerning Sanchez Energy’s future operating results and returns, the closing or anticipated effects of the divestiture of Western Catarina midstream assets referred to herein, Sanchez Energy’s strategy and plans or view of the market, or Sanchez Energy’s ability to replace or increase reserves, increase production, generate income or cash flows are forward-looking statements. Forward-looking statements are not guarantees of performance. Although Sanchez Energy believes that the expectations reflected in its forward-looking statements are reasonable and are based on reasonable assumptions, no assurance can be given that these assumptions are accurate or that any of these expectations will be achieved (in full or at all) or will prove to have been correct. Important factors that could cause Sanchez Energy’s actual results to differ materially from the expectations reflected in its forward-looking statements include, among others: Sanchez Energy’s ability to successfully execute its business and financial strategies; Sanchez Energy’s ability to replace the reserves it produces through drilling and property acquisitions; the realized benefits of Sanchez Energy’s various acquisitions including Sanchez Energy’s Catarina acquisition referred to herein and the liabilities assumed in connection with these acquisitions; the realized benefits of Sanchez Energy’s transactions with Sanchez Production Partners LP, including with respect to the divestiture of Western Catarina midstream assets referred to herein; the extent to which Sanchez Energy’s drilling plans are successful in economically developing its acreage in, and to produce reserves and achieve anticipated production levels from, its existing and future projects; the accuracy of reserve estimates, which by their nature involve the exercise of professional judgment and may therefore be imprecise; the extent to which Sanchez Energy can optimize reserve recovery and economically develop its plays utilizing horizontal and vertical drilling, advanced completion technologies and hydraulic fracturing; Sanchez Energy’s ability to successfully execute its hedging strategy and the resulting realized prices therefrom; competition in the oil and gas exploration and production industry for employees and other personnel, equipment, materials and services and, related thereto, the availability and cost of employees and other personnel, equipment, materials and services; Sanchez Energy’s ability to access the credit and capital markets to obtain financing on terms it deems acceptable, if at all, and to otherwise satisfy its capital expenditure requirements; the availability, proximity and capacity of, and costs associated with, gathering, processing, compression and transportation facilities; the timing and extent of changes in prices for, and demand for, crude oil and condensate, natural gas liquids, natural gas and related commodities; Sanchez Energy’s ability to compete with other companies in the oil and natural gas industry; the impact of, and changes in, government policies, laws and regulations, including tax laws and regulations, environmental laws and regulations relating to air emissions, waste disposal, hydraulic fracturing and access to and use of water, laws and regulations imposing conditions and restrictions on drilling and completion operations and laws and regulations with respect to derivatives and hedging activities; developments in oil-producing and natural-gas producing countries; Sanchez Energy’s ability to effectively integrate acquired crude oil and natural gas properties into its operations, fully identify existing and potential problems with respect to such properties and accurately estimate reserves, production and costs with respect to such properties; unexpected results of litigation filed against Sanchez Energy; the extent to which Sanchez Energy’s crude oil and natural gas properties operated by others are operated successfully and economically; the use of competing energy sources and the development of alternative energy sources; the extent to which Sanchez Energy incurs uninsured losses and liabilities or losses and liabilities in excess of its insurance coverage; and the other factors described under ITEM 1A, “Risk Factors,” in Sanchez Energy’s Annual Report on Form 10-K for the fiscal year ended December 31 and any updates to those factors set forth in its subsequent Quarterly Reports on Form 10-Q or Current Reports on Form 8-K. In light of these risks, uncertainties and assumptions, the events anticipated by Sanchez Energy’s forward-looking statements may not occur, and, if any of such events do, Sanchez Energy may not have correctly anticipated the timing of their occurrence or the extent of their impact on its actual results. Accordingly, you should not place any undue reliance on any of Sanchez Energy’s forward-looking statements. Any forward-looking statement speaks only as of the date on which such statement is made and Sanchez Energy undertakes no obligation to correct or update any forward-looking statement, whether as a result of new information, future events or otherwise, except as required by applicable law. Oil and Gas Reserves The Securities and Exchange Commission (“SEC”) requires oil and gas companies, in their filings with the SEC, to disclose “proved oil and gas reserves” (i.e., quantities of oil and gas that are estimated with reasonable certainty to be economically producible) and permits oil and gas companies to disclose “probable reserves” (i.e., quantities of oil and gas that are as likely as not to be recovered) and “possible reserves” (i.e., additional quantities of oil and gas that might be recovered, but with a lower probability than probable reserves). We may use certain terms in this presentation, such as “resource potential” that the SEC’s guidelines strictly prohibit us from including in filings with the SEC. The calculation of resource potential, and any other estimates of reserves and resources that are not proved, probable or possible reserves are not necessarily calculated in accordance with SEC guidelines. Investors are urged to consider closely the disclosure in Sanchez Energy’s Annual Report on Form 10-K for the fiscal year ended December 31. Non-GAAP Measures Included in this presentation are certain non-GAAP financial measures as defined under Securities and Exchange Commission Regulation G. Investors are urged to consider closely the disclosure in Sanchez Energy’s Annual Report on Form 10-K for the fiscal year ended December 31, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K and the reconciliation to GAAP measures provided in this presentation. 2 © 2016 Sanchez Energy Corporation

Adjusted 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 deri vatives; (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 prope rties; and (10) other non-recurring items that we deem appropriate; LESS: (1) premiums on commodity derivative contracts; (2) interest income; (3)Amortization of deferred gain on Western Catarina Midstream Divestiture; and (4) 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 statemen ts, 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 co st 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. Standardized measure is calculated in accordance with Statement of Financial Accounting Standards No. 69, “Disclosures About Oil and Gas P roducing Activities,” as codified in ASC Topic 932, “Extractive Activities—Oil and Gas.” For further information regarding the calculation of the standardized measure, see “Unaudited Supplementary Information ” included in the financial statements included in our Annual Report for the fiscal year ended December 31. 32 © 2016 Sanchez Energy Corporation Explanation of Non-GAAP Measures Reconciliation of PV-10 To Standardized Measure ($MM) Reconciliation of Net Income (Loss) To Adjusted EBITDA ($M)
