2 Disclaimer Forward Looking Statements This presentation contains “forward-looking statements.” Forward-looking statements are based on current expectations and include any statement that does not directly relate to a current or historical fact. Such statements include those relating to pending acquisitions and associated costs, acreage, production, reserves, and other matters; drilling locations and potential drilling activities; production and sales volumes; proved, probable and possible reserves; operating and administrative costs; future operating or financial results; cash flow and anticipated liquidity; business strategy; future dividend policies and other matters. These forward-looking statements may generally, but not always, be identified by words such as “estimated”, “projected”, “potential”, “anticipated”, “forecasted” or other words that convey the uncertainty of future events or outcomes. Although we believe the expectations and forecasts reflected in these and other forward-looking statements are reasonable, we can give no assurance they will prove to have been correct. These statements are based on current plans and assumptions and are subject to a number of risks and uncertainties as further outlined in our Forms 10-K and 10-Q. Therefore, the actual results may differ materially from the expectations, estimates or assumptions expressed in or implied by any forward-looking statement, and we caution readers not to place undue reliance on these forward looking statements, which speak only as of the date of this presentation. In particular, the pending acquisition disclosed in this presentation may not be consummated or, if it is, may be consummated upon materially different terms than currently anticipated and set forth in this presentation, including, for instance, as a consequence of the exercise of preferential purchase rights held by third parties which may dramatically reduce the acreage, reserves and production acquired. We undertake no obligation to update these forward looking statements to reflect events or circumstances occurring after the date of this presentation. Current SEC rules regarding oil and gas reserves information allow oil and gas companies to disclose in filings with the SEC not only proved reserves, but also probable and possible reserves that meet the SEC’s definitions of such terms. We disclose only proved reserves in our filings with the SEC. Our proved reserves as of June 30, 2021, were estimated by our independent petroleum engineering firm. In this presentation, proved reserves associated with acquired properties and probable and possible reserves, have been estimated by the Company’s internal staff of engineers. Estimates of probable and possible reserves are by their nature more speculative than estimates of proved reserves and are subject to greater uncertainties, and accordingly the likelihood of recovering those reserves is subject to substantially greater risk. We also disclose proved and unproved drilling locations in this presentation. Actual locations drilled and quantities that may be ultimately recovered from the Company’s interest may differ substantially from these estimates. There is no commitment by the Company to drill all of the drilling locations that have been attributed these quantities. Factors affecting ultimate recovery include the scope of the Company’s drilling program, which will be directly affected by the decisions of the operators of our properties, availability of capital, drilling and production costs, availability of drilling and completion services and equipment, drilling results, agreement terminations, regulatory approvals and actual drilling results, including geological and mechanical factors affecting recovery rates. Estimates of reserves may change significantly as development of the Company’s oil and gas assets provides additional data. Adjusted EBITDA is a non-GAAP financial measure that is used as a supplemental financial measure by our management and by external users of our financial statements, 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 costs 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 flows provided by (used in) operating activities or any other measure of financial performance or liquidity presented in accordance with U.S. 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. The Company defines Adjusted EBITDA as net income (loss) plus interest expense, income tax expense (benefit), depreciation, depletion and amortization (DD&A), stock-based compensation, other amortization and accretion, ceiling test impairment and other impairments, unrealized loss (gain) on change in fair value of derivatives, and other non-cash expense (income) items.

19 N o n - G A A P R e c o n c i l i a t i o n Adjusted EBITDA Reconciliation Adjusted EBITDA is a non-GAAP financial measure that is used as a supplemental financial measure by our management and by external users of our financial statements, 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 costs 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 flows provided by (used in) operating activities or any other measure of financial performance or liquidity presented in accordance with U.S. 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. The Company defines Adjusted EBITDA as net income (loss) plus interest expense, income tax expense (benefit), depreciation, depletion and amortization (DD&A), stock- based compensation, other amortization and accretion, ceiling test impairment and other impairments, unrealized loss (gain) on change in fair value of derivatives, and other non-cash expense (income) items.
