UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

FOR EARTHSTONE ENERGY, INC.

Earthstone Energy, Inc., a Delaware corporation (“Earthstone” or the “Company”), Earthstone Energy Holdings, LLC, a Delaware limited liability company (“EEH”), Lynden USA Inc., a Utah corporation (“Lynden”), Lynden USA Operating, LLC, a Texas limited liability company (“Lynden Sub”), Bold Energy Holdings, LLC, a Texas limited liability company (“Bold Holdings”), and Bold Energy III LLC, a Texas limited liability company (“Bold”), entered into a contribution agreement dated as of November 7, 2016 and as amended on March 21, 2017 (the “Contribution Agreement”). The purpose of the Contribution Agreement was to provide for, among other things described below, the business combination between EEH and Bold, which owns significant developed and undeveloped oil and natural gas properties in the Midland Basin of Texas (the “Transaction”).

The Transaction was structured in a manner commonly known as an “Up-C.” Under this structure and the Contribution Agreement, (i) Earthstone recapitalized its common stock into two classes – Class A common stock, $0.001 par value per share (the “Class A Common Stock”), and Class B common stock, $0.001 par value per share (the “Class B Common Stock”), and all of Earthstone’s existing outstanding common stock, $0.001 par value per share (the “Common Stock”), was recapitalized on a one-for-one basis for Class A Common Stock (the “Recapitalization”); (ii) Earthstone transferred all of its membership interests in Earthstone Operating, LLC, Sabine River Energy, LLC, EF Non-Op, LLC and Earthstone Legacy Properties, LLC (formerly Earthstone GP, LLC) and $36,071 in cash from the sale of Class B Common Stock to Bold Holdings (collectively, the “Earthstone Assets”) to EEH, in exchange for 16,791,296 membership units of EEH (the “EEH Units”); (iii) Lynden transferred all of its membership interests in Lynden Sub to EEH in exchange for 5,865,328 EEH Units; (iv) Bold Holdings transferred all of its membership interests in Bold to EEH in exchange for 36,070,828 EEH Units and purchased 36,070,828 shares of Class B Common Stock issued by Earthstone for $36,071; and (v) Earthstone granted an aggregate of 150,000 fully vested shares of Class A Common Stock under Earthstone’s 2014 Long-Term Incentive Plan, as amended (the “Plan”), to certain employees of Bold. Each EEH Unit held by Bold Holdings or its permitted transferees, together with one share of Class B Common Stock, are convertible into Class A Common Stock on a one-for-one basis.

The Transaction closed on May 9, 2017 and Bold Holdings owned approximately 61.3% of the outstanding shares of Class A Common Stock, on a fully diluted, as converted basis. The EEH Units and the shares of Class B Common Stock issued to Bold Holdings were not registered under the Securities Act of 1933, as amended (the “Securities Act”), but were issued by EEH and Earthstone in reliance on the exemption provided under Section 4(a)(2) of the Securities Act.

The Class A Common Stock is listed on the New York Stock Exchange (the “NYSE”) under the symbol “ESTE.” The closing sale price of the Common Stock on May 9, 2017 was $13.58 per share.

As previously disclosed in its Current Report on Form 8-K filed on May 24, 2016 with the Securities and Exchange Commission (the
“SEC”), on May 18, 2016, Earthstone completed the acquisition (the “Lynden Acquisition”) of Lynden Energy Corp. (“Lynden Corp.”). Earthstone filed a Form 8-K/A on June 3, 2016 for the purpose of providing unaudited pro forma condensed combined financial statements giving effect to Lynden Acquisition, as required by Item 9.01(b) of Form 8-K.

The following unaudited pro forma condensed combined financial information as of March 31, 2017 and for the three months then ended is derived from the historical consolidated financial statements of Earthstone and Bold, and has been adjusted to reflect the acquisition of Bold by Earthstone. Certain of Bold’s historical amounts have been reclassified to conform to Earthstone’s financial statement presentation. The unaudited pro forma condensed combined balance sheet as of March 31, 2017 gives effect to the Transaction as if it had occurred on March 31, 2017. The unaudited pro forma condensed combined statements of operations for the three months ended March 31, 2017 and for the year ended December 31, 2016 give effect to the Transaction and Lynden Acquisition as if they had occurred on January 1, 2016.

F-1

The unaudited pro forma condensed combined financial statements reflect pro forma adjustments based on available information and certain assumptions that Earthstone believes are reasonable which include the following:

• Earthstone’s acquisitions of Bold and Lynden are accounted for using the acquisition method of accounting for business combinations;

• Liabilities are recognized for transaction related costs;

• Depreciation, depletion and amortization and accretion expense are adjusted due to the fair value adjustments to oil and gas properties and asset retirement obligations in connection with the Transaction and the Lynden Acquisition;

• Estimated tax impacts of the pro forma adjustments; and

• In the case of the unaudited pro forma condensed combined financial statements of operations data, the Lynden Acquisition as described in Note 3 to the historical consolidated financial statements of Earthstone’s Annual Report on Form 10-K for the year ended December 31, 2016.

Assumptions and estimates underlying the pro forma adjustments are more fully described in the accompanying notes, which should be read in conjunction with the unaudited pro forma condensed combined financial statements.

The unaudited pro forma condensed combined financial information does not purport to represent what Earthstone’s financial position would have been had the Transaction actually been consummated on March 31, 2017, or what Earthstone’s financial position would have been had the Transaction and the Lynden Acquisition actually been consummated on January 1, 2016. The unaudited pro forma condensed combined financial information is not indicative of Earthstone’s future financial position or results of operations and does not reflect future events that may occur after the Transaction, including, but not limited to, the anticipated realization of ongoing savings from operating efficiencies, or offsetting unforeseen incremental costs. The unaudited pro forma condensed combined financial statements have been derived from and should be read in conjunction with the historical consolidated financial statements and accompanying notes contained in the Earthstone Annual Report on Form 10-K for the year ended December 31, 2016, Earthstone’s Quarterly Report on Form 10-Q for the three months ended March 31, 2017 incorporated herein by reference, and the historical financial statements of Bold as of December 31, 2016 and for the three years then ended, and as of March 31, 2017 and the three months then ended included in this report.

The unaudited pro forma condensed combined financial statements were prepared using the acquisition method of accounting for business combinations with Earthstone treated as the acquiring entity. Accordingly, the aggregate value of the consideration paid by Earthstone to complete the Transaction was allocated to the assets acquired and liabilities assumed from the Transaction based upon their estimated fair values on the closing date of the Transaction. Earthstone has not completed the detailed valuations necessary to estimate the fair value of the assets acquired and the liabilities assumed in the Transaction and the related allocations of purchase price, nor has Earthstone identified all adjustments necessary to conform Bold’s accounting policies to Earthstone’s accounting policies. Additionally, a final determination of the fair value of assets acquired and liabilities assumed in the Transaction will be based on the actual net tangible and intangible assets and liabilities of Bold that existed as of the closing date of the Transaction. Accordingly, the pro forma purchase price adjustments presented herein are preliminary, and may not reflect any final purchase price adjustments. Earthstone estimated the fair value of Bold’s assets and liabilities based on preliminary work performed by third-party valuation specialists. As the final valuations are performed, increases or decreases in the fair value of relevant balance sheet amounts will result in adjustments that may result in material differences from the information presented herein.

Below is the unaudited pro forma condensed combined financial information and related notes thereto which give effect to the Transaction and the Lynden Acquisition. The following unaudited pro forma condensed combined financial information sets forth:

(i) Pro forma adjustments giving effect to the Transaction and the Lynden Acquisition as if such transactions had been completed on January 1, 2016, the beginning of the earliest period presented, for purposes of the unaudited pro forma condensed combined statements of operations. The pro forma adjustments made are (1) directly attributable to the Transaction and the Lynden Acquisition, (2) factually supportable, and (3) expected to have a continuing impact on the consolidated results, and

(ii) Earthstone and Lynden Corp. have fiscal year ends on December 31 and June 30, respectively.

The unaudited pro forma condensed combined balance sheet as of March 31, 2017 has been derived from:

• the unaudited historical condensed consolidated balance sheet of Earthstone as of March 31, 2017; and

• the unaudited historical condensed consolidated balance sheet of Bold as of March 31, 2017.

F-2

The unaudited pro forma condensed combined statement of operations for the three months ended March 31, 2017 has been derived from:

• the unaudited historical consolidated statement of operations of Earthstone for the three months ended March 31, 2017; and

• the unaudited historical consolidated statement of operations of Bold for the three months ended March 31, 2017.

The unaudited pro forma condensed combined statement of operations for the year ended December 31, 2016 has been derived from:

• the audited historical consolidated statement of operations of Earthstone for the year ended December 31, 2016;

• the unaudited historical condensed consolidated interim statement of income (loss) and comprehensive income (loss) of Lynden Corp. for the three months ended March 31, 2016; and

• the audited historical consolidated statement of operations of Bold for the year ended December 31, 2016.

EARTHSTONE ENERGY INC.

NOTES TO THE UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

Note 1.  Basis of Presentation

Financial Accounting Standards Board (“FASB”)’s Accounting Standards Codification (“ASC”) 805, Business Combinations (“ASC 805”), requires, among other things, that assets acquired and liabilities assumed be recognized at their fair values, as determined in accordance with ASC 820, Fair Value Measurements, as of the acquisition date. In addition, the applicable accounting literature requires that consideration transferred be measured at the closing date of the acquisition, which may be different than the amount of consideration assumed in this unaudited pro forma condensed combined financial information.

The historical consolidated financial statements have been adjusted in the unaudited pro forma condensed combined financial statements to give effect to pro forma events that are (1) directly attributable to the Lynden Acquisition and the Transaction, (2) factually supportable and (3) with respect to the pro forma condensed combined statements of operations expected to have a continuing impact on the consolidated results following the business combination. The pro forma adjustments that are described in the accompanying notes and are based on available information and certain assumptions that Earthstone believes are reasonable; however, actual results may differ from those reflected in these statements. The unaudited pro forma condensed combined statements do not purport to represent what Earthstone’s financial position or results of operations would have been if the Lynden Acquisition and the Transaction had occurred on the dates indicated above, nor are they indicative of Earthstone’s future financial position or results of operations. Certain information normally included in financial statements and the accompanying notes prepared has been condensed or omitted. These unaudited pro forma condensed combined financial statements should be read in conjunction with the historical financial statements and related notes of Earthstone and Bold for the periods presented.

Under the acquisition method of accounting for business combinations, the assets acquired and liabilities assumed will be recorded as of the completion of the Transaction, primarily at their respective fair values and added to those of Earthstone. The results of operations of Bold will be reflected in the financial statements and reported results of operations of Earthstone from the date of the completion of the acquisition and Earthstone’s financial statements will not be retroactively restated to reflect the historical financial position or results of operations of Bold.

Note 2. Accounting Policies and Presentation

The unaudited pro forma condensed combined balance sheet as of March 31, 2017 and the unaudited pro forma condensed combined statements of operations for the three months ended March 31, 2017 and the year ended December 31, 2016 have been compiled in a manner consistent with the accounting policies adopted by Earthstone. Certain reclassifications and adjustments have been made to Bold’s historical financial information presented herein to conform to Earthstone’s historical presentation.

Note 3.  Preliminary Purchase Price Allocation

The preliminary allocation of the total purchase price in the Transaction is based upon management’s estimates of and assumptions related to the fair value of assets to be acquired and liabilities to be assumed as of March 31, 2017 using currently available information. Because the unaudited pro forma condensed combined financial information has been prepared based on these preliminary estimates, the final purchase price allocation and the resulting effect on financial position and results of operations may differ significantly from the pro forma amounts included herein.

The preliminary purchase price allocation is subject to change due to several factors, including but not limited to changes in the estimated fair value of Bold’s assets acquired and liabilities assumed as of the closing date of the Transaction, which could result from changes in future oil and natural gas commodity prices, reserve estimates, interest rates, as well as other factors.

The consideration transferred, fair value of assets acquired and liabilities assumed by us as follows (in thousands, except unit and share amounts and stock price):
