Basis of Presentation

The condensed consolidated financial statements include the accounts of the Company and its subsidiaries after all significant intercompany balances and transactions have been eliminated upon consolidation. The Company hasone reportable segment, the upstream segment.

On March 5, 2024, the Company exercised certain of its demand rights, pursuant to a registration rights agreement initially entered into on June 23, 2014, as amended and restated on May 9, 2018 and November 10, 2023, and on March 8, 2024, completed a public offering of approximately 13.23 million shares of Viper’s Class A common stock at a price of $35.00 per share for proceeds, net of underwriters’ discount, of approximately $451 million. After this offering, the Company owned less than 50% of Viper’s combined outstanding Class A common stock and Class B common stock, resulting in Viper no longer being a controlled company under the Nasdaq rules.

As of June 30, 2025, the Company owned approximately 54% of Viper’s combined outstanding Class A common stock and Class B common stock. The Company determined, in each case, that it controls the activities of Viper in accordance with the guidance for variable interest entities in Accounting Standards Codification (“ASC”) Topic 810, “Consolidation,” and therefore continues to consolidate Viper in the Company’s financial statements at June 30, 2025. See further discussion of the Company’s determination that Viper is a variable interest entity (“VIE”) in Note 2—Summary of Significant Accounting Policies. The results of operations attributable to the non-controlling interest in Viper are presented within equity and net income and are shown separately from the equity and net income attributable to the Company.

These condensed consolidated financial statements have been prepared by the Company without audit, pursuant to the rules and regulations of the SEC. They reflect all adjustments that are, in the opinion of management, necessary for a fair statement of the results for interim periods, on a basis consistent with the annual audited financial statements. All such adjustments are of a normal recurring nature. Certain information, accounting policies and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been omitted pursuant to SEC rules and regulations, although the Company believes the disclosures are adequate to make the information presented not misleading. This Quarterly Report on Form 10–Q should be read in conjunction with the Company’s most recent Annual Report on Form 10–K for the fiscal year ended December 31, 2024, which contains a summary of the Company’s significant accounting policies and other disclosures.
