Disclaimer Forward-Looking Statements This presentation contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Statements that are not strictly historical statements constitute forward-looking statements and may often, but not always, be identified by the use of such words such as “expects,” “believes,” “intends,” “anticipates,” “plans,” “estimates,” “guidance,” “potential,” “possible,” or “probable” or statements that certain actions, events or results “may,” “will,” “should,” or “could” be taken, occur or be achieved. The forward-looking statements include statements about the expected future reserves, production, financial position, business strategy, revenues, earnings, costs, capital expenditures and debt levels of the Company, and plans and objectives of management for future operations. Forward-looking statements are based on current expectations and assumptions and analyses made by Earthstone and its management in light of experience and perception of historical trends, current conditions and expected future developments, as well as other factors appropriate under the circumstances. However, whether actual results and developments will conform to expectations is subject to a number of material risks and uncertainties, including but not limited to: risks relating to any unforeseen liabilities; declines in oil, natural gas liquids or natural gas prices; the level of success in exploration, development and production activities; adverse weather conditions that may negatively impact development or production activities; the timing of exploration and development expenditures; inaccuracies of reserve estimates or assumptions underlying them; revisions to reserve estimates as a result of changes in commodity prices; impacts to financial statements as a result of impairment write-downs; risks related to level of indebtedness and periodic redeterminations of the borrowing base under the Company’s credit agreement; Earthstone’s ability to generate sufficient cash flows from operations to meet the internally funded portion of its capital expenditures budget; Earthstone’s ability to obtain external capital to finance exploration and development operations and acquisitions; the ability to successfully complete any potential asset acquisitions and the risks related thereto; the impacts of hedging on results of operations; uninsured or underinsured losses resulting from oil and natural gas operations; Earthstone’s ability to replace oil and natural gas reserves; and any loss of senior management or key technical personnel. Earthstone’s 2017 Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, recent current reports on Form 8-K and any amendments of such filings, and other Securities and Exchange Commission (“SEC”) filings discuss some of the important risk factors identified that may affect Earthstone’s business, results of operations, and financial condition. Earthstone undertakes no obligation to revise or update publicly any forward-looking statements except as required by law. Industry and Market Data This presentation has been prepared by Earthstone and includes market data and other statistical information from third-party sources, including independent industry publications, government publications or other published independent sources. Although Earthstone believes these third-party sources are reliable as of their respective dates, Earthstone has not independently verified the accuracy or completeness of this information. Some data are also based on Earthstone’s good faith estimates, which are derived from its review of internal sources as well as the third-party sources described above. 2


 
Disclaimer Oil and Gas Reserves The SEC generally permits oil and gas companies, in filings made with the SEC, to disclose estimated proved reserves, which are estimates of reserve quantities that geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing economic and operating conditions, and certain probable and possible reserves that meet the SEC’s definitions for such terms. Earthstone discloses only estimated proved reserves in its filings with the SEC. Earthstone’s estimated proved reserves as of December 31, 2017 contained in this presentation were prepared by Cawley, Gillespie & Associates, Inc., an independent engineering firm (“CG&A”), and comply with definitions promulgated by the SEC. Additional information on Earthstone’s estimated proved reserves is contained in Earthstone’s filings with the SEC. This presentation also contains Earthstone’s internal estimates of its potential drilling locations, which may prove to be incorrect in a number of material ways. The actual number of locations that may be drilled may differ substantially. Certain estimates of proved reserves contained herein were independently prepared by CG&A utilizing NYMEX 5-year strip prices (future prices) for oil, natural gas and NGL’s as of December 31, 2017. Management believes that utilizing an alternate pricing case better represents the value of the reserves and are better aligned with fair value of reserves. Management also believes the alternate pricing case is useful to investors because it uses future prices and not historical prices in its planning and strategic decision making. In addition to using NYMEX 5-year strip prices, future plugging and abandonment costs net of salvage value have been excluded from the NYMEX 5-year strip price reserves case. 3

Reconciliation of Non-GAAP Financial Measure – Adjusted EBITDAX Adjusted EBITDAX (as defined below) is presented herein and reconciled from the GAAP measure of net income because of its wide acceptance by the investment community as a financial indicator. We define “Adjusted EBITDAX” as net income plus accretion of asset retirement obligations; depletion, depreciation and amortization; interest expense, net; (gain) on sale of oil and gas properties; unrealized loss on hedges; non-cash stock-based compensation; and income tax (benefit). Our Adjusted EBITDAX measure provides additional information that may be used to better understand our operations. Adjusted EBITDAX is one of several metrics that we use as a supplemental financial measurement in the evaluation of our business and should not be considered as an alternative to, or more meaningful than, the GAAP measure of net income as an indicator of operating performance. Certain items excluded from Adjusted EBITDAX are significant components in understanding and assessing a company’s financial performance, such as a company’s cost of capital and tax structure, as well as the historic cost of depreciable and depletable assets. Adjusted EBITDAX, as used by us, may not be comparable to similarly titled measures reported by other companies. We believe that Adjusted EBITDAX is a widely followed measure of operating performance and is one of many metrics used by our management team and by other users of our consolidated financial statements. For example, Adjusted EBITDAX can be used to assess our operating performance and return on capital in comparison to other independent exploration and production companies without regard to financial or capital structure and to assess the financial performance of our assets and our Company without regard to capital structure or historical cost basis. The following table provides a reconciliation of Net income to Adjusted EBITDAX for the six months ended June 30, 2018: ($000's) Q1-Q2 2018 Net income $13,663 (Gain) on sale of oil and gas properties (512) Accretion 84 Depletion, depreciation and amortization 20,520 Interest expense, net 1,223 Unrealized loss on MTM of hedges 6,858 Non-cash stock based compensation 4,013 Income tax (benefit) (53) Adjusted EBITDAX $45,796 30


 
Non-GAAP Financial Measure – PV-10 PV-10 is derived from the Standardized Measure of discounted future net cash flows, which is the most directly comparable GAAP financial measure. PV-10 is a computation of the Standardized Measure on a pre-tax basis. PV-10 is equal to the Standardized Measure at the applicable date, before deducting future income taxes, discounted at 10%. We believe that the presentation of PV-10 is relevant and useful to investors because it presents the discounted future net cash flows attributable to our estimated net proved reserves prior to taking into account future corporate income taxes, and it is a useful measure for evaluating the relative monetary significance of our oil and natural gas properties. Further, investors may utilize the measure as a basis for comparison of the relative size and value of our reserves to other companies. We use this measure when assessing the potential return on investment related to our oil and natural gas properties. PV-10, however, is not a substitute for the Standardized Measure. Our PV-10 measure and the Standardized Measure do not purport to present the fair value of our oil and natural gas reserves. Earthstone’s proved reserves as of December 31, 2017 were independently estimated by CG&A utilizing NYMEX 5-year strip prices as of December 31, 2017 (Oil – $59.55, $56.19, $53.76, $52.29, $51.67 / Gas - $2.84, $2.81, $2.82, $2.85, $2.89). 31
