Disclaimer Second Quarter 2026 Earnings Presentation 2 FORWARD LOOKING STATEMENTS The information in this presentation includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. All statements, other than statements of present or historical fact included in this presentation, regarding the consummation of the acquisition of WildFire and the transactions contemplated thereby (the “WildFire Acquisition”), the expected synergies of the WildFire Acquisition, Magnolia’s share repurchase program, Magnolia’s strategy, future operations, financial position, estimated revenues and losses, projected costs, prospects, plans and objectives of management are forward looking statements. When used in this presentation, the words could, should, will, may, believe, anticipate, intend, estimate, expect, project, the negative of such terms and other similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain such identifying words. These forward-looking statements are based on management’s current expectations and assumptions about future events. Except as otherwise required by applicable law, Magnolia disclaims any duty to update any forward-looking statements, all of which are expressly qualified by the statements in this section, to reflect events or circumstances after the date of this presentation. Magnolia cautions you that these forward-looking statements are subject to all of the risks and uncertainties, most of which are difficult to predict and many of which are beyond the control of Magnolia, incident to the development, production, gathering and sale of oil, natural gas and natural gas liquids. In addition, Magnolia cautions you that the forward looking statements contained in this presentation are subject to the following factors: (i) the expected timetable for completing the WildFire Acquisition, the results, effects and benefits of the WildFire Acquisition, future opportunities for Magnolia, other plans and expectations with respect to the WildFire Acquisition, and the anticipated impact of the WildFire Acquisition on Magnolia’s results of operations, financial position, growth opportunities and competitive position; (ii) the market prices of oil, natural gas, NGLs, and other products or services; (iii) the supply and demand for oil, natural gas, NGLs, and other products or services, including impacts of actions taken by OPEC and other state-controlled oil companies; (iv) the outcome of any legal proceedings that may be instituted against Magnolia; (v) Magnolia’s ability to realize the anticipated benefits of its acquisitions, which may be affected by, among other things, competition and the ability of Magnolia to grow and manage growth profitably; (vi) legislative, regulatory, or policy changes, including those following the change in presidential administrations; (vii) geopolitical and business conditions in key regions of the world; (viii) cybersecurity threats, including increased use of artificial intelligence technologies; and (ix) the possibility that Magnolia may be adversely affected by other economic, business, and/or competitive factors, including inflation. Should one or more of the risks or uncertainties described in this presentation occur, or should underlying assumptions prove incorrect, actual results and plans could differ materially from those expressed in any forward-looking statements. Additional information concerning these and other factors that may impact the operations and projections discussed herein can be found in Magnolia’s filings with the SEC, including its Annual Report on Form 10-K for the fiscal year ended December 31, 2025. Magnolia’s SEC filings are available publicly on the SEC’s website at www.sec.gov. NON-GAAP FINANCIAL MEASURES This presentation includes non-GAAP financial measures, including adjusted net income, free cash flow, adjusted EBITDAX, adjusted cash operating costs, adjusted cash operating margin, adjusted operating income margin and return on capital employed. Magnolia believes these metrics are useful because they allow Magnolia to more effectively evaluate its operating performance and compare the results of its operations from period to period and against its peers without regard to accounting methods or capital structure. Magnolia does not consider these non-GAAP measures in isolation or as an alternative to similar financial measures determined in accordance with GAAP. The computations of these non-GAAP measures may not be comparable to other similarly titled measures of other companies. Adjusted net income and adjusted EBITDAX should not be considered an alternative to, or more meaningful than, net income as determined in accordance with GAAP. Certain items excluded from free cash flow, adjusted net income, adjusted EBITDAX, adjusted cash operating costs, adjusted cash operating margin, adjusted operating income margin and return on capital employed are significant components in understanding and assessing a company’s financial performance and should not be construed as an inference that its results will be unaffected by unusual or non-recurring terms. As performance measures, adjusted net income, adjusted EBITDAX, adjusted cash operating costs, adjusted cash operating margin, adjusted operating income margin and return on capital employed may be useful to investors in facilitating comparisons to others in the Company’s industry because certain items can vary substantially in the oil and gas industry from company to company depending upon accounting methods, book value of assets, and capital structure, among other factors. Management believes excluding these items facilitates investors and analysts in evaluating and comparing the underlying operating and financial performance of our business from period to period by eliminating differences caused by the existence and timing of certain expense and income items that would not otherwise be apparent on a GAAP basis. As a liquidity measure, management believes free cash flow is useful for investors and widely accepted by those following the oil and gas industry as financial indicators of a company’s ability to generate cash to internally fund drilling and completion activities, fund acquisitions, and service debt. Our presentation of adjusted net income, adjusted EBITDAX, free cash flow, adjusted cash operating costs, adjusted cash operating margin, adjusted operating income margin and return on capital employed may not be comparable to similar measures of other companies in our industry. Reconciliations of non-GAAP measures included herein to the nearest corresponding GAAP measure are included in this presentation. INDUSTRY AND MARKET DATA This presentation has been prepared by Magnolia and includes market data and other statistical information from sources believed by Magnolia to be reliable, including independent industry publications, governmental publications or other published independent sources. Some data is also based on the good faith estimates of Magnolia, which are derived from its review of internal sources as well as the independent sources described above. Although Magnolia believes these sources are reliable, it has not independently verified the information and cannot guarantee its accuracy and completeness.
