Amendment: SEC Form SCHEDULE 13D/A filed by Sitio Royalties Corp.

Item 2(e) of the Schedule 13D is hereby amended and restated in its entirety as follows: On September 25, 2024, the SEC accepted an offer by OCM LP to resolve an investigation involving Sections 13(d) and 16(a) of the Securities Exchange Act of 1934 (the "Exchange Act") and Rules 13d-2 and 16a-3 thereunder, which require certain investors, like the Reporting Persons, that beneficially own the registered equity securities of a public company to file reports with the SEC of their beneficial ownership in the equity of the company, including changes in their beneficial ownership, within specified timeframes. OCM LP cooperated immediately and fully with the SEC's investigation, and, without admitting or denying the SEC's findings, in a settled proceeding agreed to cease and desist from committing or causing any violations and any future violations of Sections 13(d) and 16(a) of the Exchange Act and Rules 13d-2 and 16a-3 thereunder and to pay a $375,000 penalty.

Item 4 of the Schedule 13D is hereby amended and supplemented as follows: On June 2, 2025, Sitio Royalties Corp., a Delaware corporation ("Sitio") and Sitio Royalties Operating Partnership, LP, a Delaware limited partnership and a subsidiary of Sitio ("Sitio Opco"), entered into an Agreement and Plan of Merger, dated as of June 2, 2025, (the "Merger Agreement") with Viper Energy, Inc., a Delaware corporation ("Viper"), Viper Energy Partners LLC, a Delaware limited liability company ("Viper Opco"), New Cobra Pubco, Inc., a Delaware corporation and a wholly owned subsidiary of Viper ("New Parent"), Cobra Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of New Parent ("Viper Merger Sub"), and Scorpion Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of New Parent ("Sitio Merger Sub"). Pursuant to the terms of the Merger Agreement, Viper will acquire Sitio in an all-equity transaction through: (i) the merger of Viper Merger Sub with and into Viper, with Viper continuing as the surviving corporation and a wholly owned subsidiary of New Parent, (ii) the merger of Sitio Merger Sub with and into Sitio, with Sitio continuing as the surviving corporation and a wholly owned subsidiary of New Parent, and (iii) the merger of Sitio Opco with and into Viper Opco, with Viper Opco continuing as the surviving entity, in each case on the terms set forth in the Merger Agreement (collectively, the "Mergers"). Concurrently with the execution and delivery of the Merger Agreement, on June 2, 2025, Source Energy Leasehold LP, Source Energy Permian II, LLC, Permian Mineral Acquisitions, LP, and Sierra Energy Royalties, LLC entered into a Voting and Support Agreement (the "Voting and Support Agreement"), with the Issuer and Viper, pursuant to which the Reporting Persons have agreed, until the Voting and Support Agreement terminates in accordance with its terms (the "Lock-Up Period"), to vote their shares of Class A Common Stock and their shares of Class C Common Stock and Partnership Units, as applicable, in favor of the matters to be voted upon in connection with the Mergers, subject to the terms and conditions set forth in the Voting and Support Agreement. In addition, during the Lock-Up Period, the Reporting Persons shall not transfer their shares of Class A Common Stock or their shares of Class C Common Stock and Partnership Units, subject to certain customary exceptions. The foregoing description of the Voting and Support Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Voting and Support Agreement which is attached hereto as Exhibit 99.2 and is incorporated herein by reference.

Item 5(a) of the Schedule 13D is hereby amended and restated as follows: The information set forth on lines 11 and 13 of each cover page hereto is incorporated by reference into this Item 5(a). The percentages used in this Amendment No 2. are calculated based on (i) 77,517,671 Class A Shares outstanding as of May 2, 2025, as reported in the Issuers 10-Q filed May 7, 2025, as increased by (ii) 15,443,610 Class A Shares issuable upon conversion of Class C Shares beneficially owned by the Reporting Persons (including those underlying the Allocation Rights).

The Reporting Persons have not effected any transactions related to the Common Stock during the past 60 days.

Not applicable.

The Brookfield Reporting Persons, which previously reported together with the Oaktree Reporting Persons, have been determined to no longer act together with the Oaktree Reporting Persons, and therefore have ceased to be the beneficial owners of more than five percent of the securities covered by this Amendment No. 2.
