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,” “target,” “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 benefits of the pending acquisition of Sabalo Energy, LLC, including certain interests of Shad Permian, LLC (collectively, “Shad”) acquired by Sabalo (collectively, "Sabalo") by Earthstone Energy, Inc. ("Earthstone,""ESTE"orthe"Company"),theexpectedfuturereserves,salesvolumes,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, including guidance, 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: Earthstone's ability to integrate the operations of Sabalo successfully and achieve the anticipated benefits from the Sabalo acquisition; risks relating to any unforeseen liabilities of Earthstone or Sabalo; risks related to servicing of significant debt expected to be issued in connection with the Sabalo acquisition; declines in oil, natural gas liquids (“NGLs”) 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 other 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; unforeseen technical difficulties in well drilling, completion and operation and product delivery bottlenecks; 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. The presentation contains Earthstone’s 2018 and 2019 sales volumes, production, capital expenditure and Adjusted EBITDAX guidance and such guidance after giving pro forma effect to the pending acquisition. The actual levels of production, capital expenditures, expenses and Adjusted EBITDAX may be higher or lower than these estimates due to, among other things, uncertainty in drilling schedules, changes in market demand and unanticipated delays in production. These estimates are based on numerous assumptions, including assumptions related to number of wells drilled, average spud to release times, rig count, and production rates for wells placed on production. These estimates are provided for illustration purposes only and are based on budgets and forecasts that have not been finalized. All or any of these assumptions may not prove to be accurate, which could result in actual results differing materially from estimates. If any of the rigs currently being utilized or intended to be utilized becomes unavailable for any reason, and Earthstone is not able to secure a replacement on a timely basis, we may not be able to drill, complete and place on production the expected number of wells. No assurance can be made that new wells will produce in line with historic performance, or that existing wells will continue to produce in line with expectations. Our ability to finance our 2018, 2019 and future capital budgets is subject to numerous risks and uncertainties, including reductions in our borrowing base, volatility in commodity prices and the potential for unanticipated increases in costs associated with drilling, production and transportation. In addition, our production estimates assume there will not be any new federal, state or local regulation applicable to us, or an interpretation of existing regulations, that will be materially adverse to our business. For additional discussion of the factors that may cause us not to achieve our production estimates, see Earthstone’s filings with the SEC, including its forms 10-K, 10-Q and 8-K and any amendments thereto. We do not undertake any obligation to release publicly the results of any future revisions we may make to this prospective data or to update this prospective data to reflect events or circumstances after the date of this presentation. Therefore, you are cautioned not to place undue reliance on this information. 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. Additional information regarding Earthstone’s and Sabalo’s estimated proved reserves is contained in Earthstone’s filings with the SEC. Certain estimates of proved reserves contained herein were independently prepared by Earthstone management utilizing NYMEX 5-year strip prices (future prices) for oil, natural gas and NGL’s as of October 1, 2018. Management 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. Future plugging and abandonment costs net of salvage value have been excluded from the NYMEX 5-year strip price reserves case. Actual quantities that may be ultimately recovered may differ substantially from estimates. Factors affecting ultimate recovery include the scope of the operators' ongoing drilling programs, which will be directly affected by the availability of capital, drilling and production costs, availability of drilling services and equipment, drilling results, lease expirations, transportation constraints, regulatory approvals and other factors, and actual drilling results, including geological and mechanical factors affecting recovery rates. Estimates of potential resources may also change significantly as the development of the properties underlying Earthstone's mineral interests provides additional data. This presentation also contains Earthstone’s internal estimates of its and Sabalo’s 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. Adjusted EBITDAX Earthstone uses Adjusted EBITDAX, a financial measure that is not presented in accordance with United States generally accepted accounting principles (“GAAP”). Adjusted EBITDAX is a supplemental non-GAAP financial measure that is used by Earthstone’s management team and external users of its financial statements, such as industry analysts, investors, lenders and rating agencies. Earthstone’s management team believes Adjusted EBITDAX is useful because it allows Earthstone to more effectively evaluate its operating performance and compare the results of its operations from period to period without regard to its financing methods or capital structure. Earthstone defines Adjusted EBITDAX as net income (loss) plus, when applicable, (gain) on sale of oil and gas properties; accretion; impairment expense; depletion, depreciation and amortization; exploration expense; transaction costs; interest expense; interest income; unrealized loss on mark-to-market of hedges; non-cash stock based compensation; and income tax (benefit). Earthstone excludes the foregoing items from net income (loss) in arriving at Adjusted EBITDAX because these amounts can vary substantially from company to company within their industry depending upon accounting methods and book values of assets, capital structures and the method by which the assets were acquired. Adjusted EBITDAX should not be considered as an alternative to, or more meaningful than, net income (loss) as determined in accordance with GAAP or as an indicator of Earthstone’s operating performance or liquidity. 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 costs of depreciable assets, none of which are components of Adjusted EBITDAX. Earthstone’s computation of Adjusted EBITDAX may not be comparable to other similarly titled measures of other companies or to similar measures in Earthstone’s revolving credit facility. Please see page 33 for a reconciliation of Adjusted EBITDAX to net income (loss), Earthstone’s most directly comparable financial measure calculated in accordance with GAAP, for Earthstone. PV-10 Present Value Discounted at 10% (“PV-10”) is a non-GAAP measure that differs from a measure under GAAP known as “standardized measure of discounted future net cash flows” in that PV-10 is calculated without including future income taxes. Each of Earthstone’s and Sabalo’s management believes that the presentation of the PV-10 value of their oil and natural gas properties is relevant and useful to investors because it presents the estimated discounted future net cash flows attributable to their respective estimated proved reserves independent of income tax attributes, thereby isolating the intrinsic value of the estimated future cash flows attributable to their respective reserves. Each of Earthstone’s and Sabalo’s management believes the use of a pre-tax measure provides greater comparability of assets when evaluating companies because the timing and quantification of future income taxes is dependent on company-specific factors, many of which are difficult to determine. For these reasons, each of Earthstone’s and Sabalo’s management uses and believes that the industry generally uses the PV-10 measure in evaluating and comparing acquisition candidates and assessing the potential rate of return on investments in oil and natural gas properties. PV-10 does not necessarily represent the fair market value of oil and natural gas properties. PV-10 is not a measure of financial or operational performance under GAAP, nor should it be considered in isolation or as a substitute for the standardized measure of discounted future net cash flows as defined under GAAP. 3
