Rhea-AI Filing Summary

Viper Energy, Inc. (VNOM) disclosed a series of merger-related filings and corporate charter documents. The company references an S-4 (File No. 333-288431) initially filed June 30, 2025 and declared effective July 18, 2025, which includes a definitive Joint Information Statement/Proxy Statement/Prospectus describing the Mergers and the Merger Agreement. The filing incorporates by reference an Agreement and Plan of Merger dated June 2, 2025 among Former Viper, Viper Opco, Sitio, Sitio Opco, New Viper, Viper Merger Sub and Sitio Merger Sub, and cites an 8-K filed June 4, 2025.

Positive

S-4 declared effective on July 18, 2025, indicating the prospectus/proxy statement was accepted by the SEC
Comprehensive documentation referenced: merger agreement, amended charter and bylaws, and assignment agreement are included or incorporated by reference

Negative

No financial terms or closing confirmation are present in the excerpt to assess economic impact
No shareholder vote results or effective date of the mergers are included in the provided text

Insights

TL;DR: The filing documents a completed proxy/prospectus process and a June 2, 2025 merger agreement central to VNOM's corporate transaction.

The filing explicitly notes an S-4 declared effective July 18, 2025, and incorporation by reference of an Agreement and Plan of Merger dated June 2, 2025 and related 8-K dated June 4, 2025. Those items indicate that the company has undertaken a structured disclosure process for a multi-party merger involving Former Viper, Viper Opco, Sitio entities and newly formed merger subsidiaries. The referenced amended charter and bylaws and assignment and assumption agreement are typical post-closing corporate governance and contractual housekeeping documents. Absent specific financial terms, shareholder vote outcomes, or closing confirmations in the provided text, material economic impact cannot be assessed further from this excerpt.

TL;DR: Governance documents and prospectus inclusion show legal and disclosure steps taken for a significant corporate combination.

The content lists an Amended and Restated Certificate of Incorporation and Second Amended and Restated Bylaws for Former Viper, implying governance changes accompanying the merger process. The inclusion of a Form of Assignment and Assumption Agreement and embedded Inline XBRL cover page points to formalized transfer of obligations and adherence to filing technical requirements. The direct references to exhibits and incorporated 8-Ks are consistent with thorough SEC disclosure practices for a material transaction; however, the excerpt contains no specifics on shareholder approvals, effective merger closing, or financial terms to evaluate governance or valuation implications further.

(f/k/a New Cobra Pubco, Inc.) (“New Viper”), Cobra Merger Sub, Inc., a Delaware corporation (“Viper Merger Sub”), and Scorpion Merger Sub, Inc., a Delaware corporation (“Sitio Merger Sub”).

The Merger Agreement provides for, among other things, the acquisition of Sitio by Former Viper in an all-equity transaction through: (i) the merger of Sitio Merger Sub with and into Sitio, with Sitio continuing as the surviving corporation and a wholly owned subsidiary of New Viper (the “Sitio Pubco Merger”), (ii) the merger of Viper Merger Sub with and into Former Viper, with Former Viper continuing as the surviving corporation and a wholly owned subsidiary of New Viper (the “Viper Pubco Merger” and, together with the Sitio Pubco Merger, the “Pubco Mergers”), and (iii) the merger of Sitio Opco with and into Viper Opco, with Viper Opco continuing as the surviving entity (the “Opco Merger” and, together with the Pubco Mergers, the “Mergers”), in each case on the terms set forth in the Merger Agreement.

As a result of the Mergers, among other things:

•

immediately prior to the Sitio Pubco Merger Effective Time, each award of restricted securities consisting of a number of common units representing limited partnership interests in Sitio Opco (“Sitio Opco Units”) and an equivalent number of shares of Sitio Class C Common Stock (each, a “Sitio Opco Unit Award”) that was outstanding immediately prior to the Sitio Pubco Merger Effective Time vested in full and each Sitio Opco Unit and share of Sitio Class C Common Stock subject to such Sitio Opco Unit Award was treated as described above and below, as if such Sitio Opco Unit and share of Sitio Class C Common Stock was not subject to such Sitio Opco Unit Award;

•

at the Viper Pubco Merger Effective Time, each award of restricted stock units in respect of Former Viper Class A Common Stock that was outstanding immediately prior to the Viper Pubco Merger Effective Time, whether or not subject in whole or in part to performance-based vesting conditions, was cancelled and converted into a corresponding award in respect of the same number of shares of New Viper Class A Common Stock, subject to the same terms and conditions as were applicable to the award immediately prior to the Viper Pubco Merger Effective Time; and

•

following the Pubco Mergers, at the effective time of the Opco Merger (the “Opco Merger Effective Time”, which was 12:02 a.m., Eastern Time, on August 19, 2025), (A) each Sitio Opco Unit held by Former Viper, Sitio, New Viper, or any of their wholly owned subsidiaries immediately prior to the Opco Merger Effective Time was converted into 0.4855 common units representing limited liability company membership interests in Viper Opco (the “Viper Opco Units”) and (B) each other Sitio Opco Unit issued and outstanding immediately prior to the Opco Merger Effective Time (other than certain excluded units) was converted into the right to receive (i) 0.4855 Viper Opco Units and (ii) 0.4855 shares of New Viper Class B Common Stock.
