Description of Business and Basis of Presentation	Description of Business and Basis of Presentation Organization and Nature of Operations Magnolia Oil & Gas Corporation (either individually or together with its consolidated subsidiaries, as the context requires, the “Company” or “Magnolia”) is an independent oil and natural gas company engaged in the acquisition, development, exploration, and production of oil, natural gas, and natural gas liquid (“NGL”) reserves. The Company’s oil and natural gas properties are located primarily in the Karnes and Giddings areas in South Texas where the Company primarily targets the Eagle Ford Shale and Austin Chalk formations. Magnolia’s objective is to generate stock market value over the long term through steady organic production growth, high full cycle operating margins, an efficient capital program with short economic paybacks, significant free cash flow after capital expenditures, and effective reinvestment of free cash flow. Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) and the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial reporting. Accordingly, certain disclosures normally included in an Annual Report on Form 10-K have been omitted. The consolidated financial statements and related notes included in this Quarterly Report should be read in conjunction with the Company’s consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the period ended December 31, 2024 (the “2024 Form 10-K”). Except as disclosed herein, there have been no material changes to the information disclosed in the notes to the consolidated financial statements included in the Company’s 2024 Form 10-K. In the opinion of management, all normal, recurring adjustments and accruals considered necessary to present fairly, in all material respects, the Company’s interim financial results have been included. Operating results for the periods presented are not necessarily indicative of expected results for the full year. The consolidated financial statements include the accounts of the Company and its subsidiaries after elimination of intercompany transactions and balances. The Company’s interests in oil and natural gas exploration and production ventures and partnerships are proportionately consolidated. The Company reflects a noncontrolling interest representing the interest owned by the Magnolia LLC Unit Holders through their ownership of Magnolia LLC Units in the consolidated financial statements. The noncontrolling interest is presented as a component of equity. See Note 10—Stockholders’ Equity for further discussion of the noncontrolling interest. Segment Information The Company operates in one reportable segment engaged in the acquisition, development, exploration, and production of oil and natural gas properties (“Operating segment”). Magnolia’s operations are conducted predominantly in one geographic area of the United States. The Operating segment sells oil, natural gas, and NGLs which are disaggregated on the Company’s consolidated statements of operations. The profit or loss metric used to evaluate segment performance is net income reported on the Company’s consolidated statements of operations. The measure of segment assets is reported on the Company’s consolidated balance sheets as Total Assets. Significant segment expenses are the same as those in the consolidated statements of operations.
