Management Comments

Mr. Robert J. Anderson, President and CEO of Earthstone, commented, “We achieved strong second quarter results and continue building towards what we believe will be an exceptional year for Earthstone.Our team executed and delivered these strong results while successfully integrating the assets from our IRM Acquisition into our operations and actively pursuing additional acquisitions such as the recently closed Eagle Ford and Tracker acquisitions. Our growing cash flow combined with our solid balance sheet has positioned us to be able to execute an active acquisition strategy this year that is significantly increasing our scale while expanding our opportunities for greater efficiency and profitable growth.The series of accretive acquisitions that we have announced so far this year substantially increase our production and add about 120 high-graded drilling locations while only minimally impacting our leverage levels and total G&A costs.As we fully integrate the assets acquired in the Tracker Acquisition and execute on our two-rig drilling program, we expect that our results in 2022 will further demonstrate the meaningful benefits of our consolidation strategy.”

As of June 30, 2021, we had $0.5 million in cash and $241.4 million of long-term debt outstanding under our senior secured revolving credit facility (our “Credit Facility”) with a borrowing base of $475 million. With the $233.6 million of undrawn borrowing base capacity and $0.5 million in cash, we had total liquidity of approximately $234.1 million. Adjusted for the closing of the Tracker Acquisition on July 20, 2021, we had an estimated $0.5 million in cash and $301.0 million of long-term debt outstanding under our Credit Facility with a borrowing base of $550 million. With the $249.0 million of undrawn borrowing base capacity and $0.5 million in cash, we had total liquidity of approximately $249.5 million on a combined basis. Through June 30, 2021, we had incurred $32.6 million of our estimated $130-$140 million in capital expenditures for 2021. We expect to fund our remaining 2021 capital expenditures with cash flow from operations while any excess will be used to pay down debt.

Earthstone Energy, Inc.
Non-GAAP Financial Measures
Unaudited

The non-GAAP financial measures of Adjusted Diluted Shares, Adjusted EBITDAX, Adjusted Net Income, All-In Cash Costs, Free Cash Flow, Adjusted Working Capital Deficit and Operating Margin per Boe, as defined and presented below, are intended to provide readers with meaningful information that supplements our financial statements prepared in accordance with accounting principles generally accepted in the United States (“GAAP”). Further, these non-GAAP measures should only be considered in conjunction with financial statements and disclosures prepared in accordance with GAAP and should not be considered in isolation or as a substitute for GAAP measures, such as net income or loss, operating income or loss or any other GAAP measure of financial position or results of operations. Adjusted EBITDAX and Adjusted Net Income are presented herein and reconciled from the GAAP measure of net (loss) income because of their wide acceptance by the investment community as a financial indicator.

I. Adjusted Diluted Shares

We define “Adjusted Diluted Shares” as the weighted average shares of Class A Common Stock - Diluted outstanding plus the weighted average shares of Class B Common Stock outstanding.

Our Adjusted Diluted Shares measure provides a comparable per share measurement when presenting results such as Adjusted EBITDAX and Adjusted Net Income that include the interests of both Earthstone and the noncontrolling interest. Adjusted Diluted Shares is used in calculating several metrics that we use as supplemental financial measurements in the evaluation of our business, none of which should be considered as an alternative to, or more meaningful than, net income as an indicator of operating performance.

Adjusted Diluted Shares for the periods indicated:

	Three Months Ended		Six Months Ended
	June 30,		June 30,
	2021	2020	2021	2020
Class A Common Stock - Diluted	44,127,718	29,858,162	43,457,043	29,677,795
Class B Common Stock	34,409,867	35,059,412	34,455,755	35,145,179
Adjusted Diluted Shares	78,537,585	64,917,574	77,912,798	64,822,974

II. Adjusted EBITDAX

The non-GAAP financial measure of Adjusted EBITDAX (as defined below), as calculated by us below, is intended to provide readers with meaningful information that supplements our financial statements prepared in accordance with GAAP. Further, this non-GAAP measure should only be considered in conjunction with financial statements and disclosures prepared in accordance with GAAP and should not be considered in isolation or as a substitute for GAAP measures, such as net income or loss, operating income or loss or any other GAAP measure of financial position or results of operations. Adjusted EBITDAX is presented herein and reconciled from the GAAP measure of net (loss) income because of its wide acceptance by the investment community as a financial indicator.

We define “Adjusted EBITDAX” as net (loss) income plus, when applicable, accretion of asset retirement obligations; impairment expense; depreciation, depletion and amortization; interest expense, net; transaction costs; (gain) loss on sale of oil and gas properties, net; rig termination expense; exploration expense; unrealized loss (gain) on derivative contracts; stock-based compensation (non-cash); and income tax (benefit) expense.

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, net (loss) 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

11

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 (loss) income to Adjusted EBITDAX for the periods indicated:

($000s, except per Boe data)	Three Months Ended				Six Months Ended

(2)Represents reported sales volumes.

(3)Barrels of oil equivalent have been calculated on the basis of six thousand cubic feet (Mcf) of natural gas equals one barrel of oil equivalent (Boe).

III. Adjusted Net Income

We define “Adjusted Net Income” as net (loss) income plus, when applicable, unrealized loss (gain) on derivative contracts; impairment expense; (gain) loss on sale of oil and gas properties; write-off of deferred financing costs; transaction costs; and the associated changes in estimated income tax.

Our Adjusted Net Income measure provides additional information that may be used to further understand our operations. Adjusted Net Income 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, net (loss) income as an indicator of operating performance. Certain items excluded from Adjusted Net Income 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 Net Income, as used by us, may not be comparable to similarly titled measures reported by other companies. We believe that Adjusted Net Income 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 Net Income 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.

IV. All-In Cash Costs

We define “All-In Cash Costs” as lease operating expenses plus production and ad valorem taxes, interest expense, net, and general and administrative expense (excluding stock-based compensation).

Our All-In Cash Costs measure provides additional information that may be used to further understand our total cost of production. We use All-In Cash Costs as a supplemental financial measurement in the evaluation of our operational performance. We believe that investors benefit from having access to the same financial measures that our management uses in evaluating our results. All-In Cash Costs should not be considered as an alternative to, or more meaningful than, net (loss) income as an indicator of operating performance. All-In Cash Costs, as used by us, may not be comparable to similarly titled measures reported by other companies.

All-In Cash Costs for the periods indicated:

($000s, except per Boe data)	Three Months Ended				Six Months Ended
	June 30,				June 30,
	2021		2020		2021		2020
Lease operating expense	$	11,747	$	5,588	$	22,596	$	14,927

All-In Cash Costs per Boe	$	11.65	$	10.11	$	12.12	$	11.62

(1)Represents reported sales volumes.

(2)Barrels of oil equivalent have been calculated on the basis of six thousand cubic feet (Mcf) of natural gas equals one barrel of oil equivalent (Boe).

V. Free Cash Flow

Free Cash Flow is a measure that we use as an indicator of our ability to fund our development activities. We define Free Cash Flow as Adjusted EBITDAX (defined above), less interest expense, less accrual-based capital expenditures.

Management believes that Free Cash Flow, which measures our ability to generate additional cash from our business operations, is an important financial measure for use in evaluating the Company's financial performance. Free Cash Flow should be considered in addition to, rather than as a substitute for, consolidated net income as a measure of our performance and net cash provided by operating activities as a measure of our liquidity.

Free Cash Flow for the periods indicated:

($000s)	Three Months Ended				Six Months Ended
	June 30,				June 30,
	2021		2020		2021		2020
Adjusted EBITDAX	$	53,668	$	39,846	$	97,511	$	78,049

Capital expenditures (accrual basis)	(22,820)		(3,238)		(32,621)		(45,064)
Free Cash Flow	$	28,447	$	35,323	$	60,272	$	29,964

VI. Operating Margin per Boe and Operating Margin per Boe (including realized hedge settlements)

Operating Margin per Boe is a non-GAAP financial measure that we use to evaluate our operating performance on a per Boe basis. We define Operating Margin per Boe as average realized price per Boe minus lease operating expense per BOE and production and ad valorem taxes per Boe. Operating Margin per Boe (including realized hedge settlements) is calculated as the sum of Operating Margin per Boe and Realized hedge settlements per Boe.

Our Operating Margin per Boe measure provides additional information that may be used to further understand our operating margins. We use Operating Margin per Boe as a supplemental financial measurement in the evaluation of our operational performance. We believe that investors benefit from having access to the same financial measures that our management uses in evaluating our results. Operating Margin per Boe should not be considered as an alternative to, or more meaningful than, net (loss) income as an indicator of operating performance. Operating Margin per Boe, as used by us, may not be comparable to similarly titled measures reported by other companies.
