[SCHEDULE 13G/A] Sitio Royalties Corp. SEC Filing

Rhea-AI Filing Summary

Sitio Royalties Corp.'s Schedule 13G/A is filed by multiple Blackstone-related entities and Stephen A. Schwarzman to disclose holdings in the issuer's Class A Common Stock (CUSIP 82983N108). The filing states that, following the Merger Agreement dated June 2, 2025, on August 19, 2025 Sitio's Class C common stock was cancelled and Opco units converted into: 0.4855 LLC units in Viper Energy Partners LLC and 0.4855 shares of Class B common stock of Viper Energy, Inc. Each Reporting Person's cover page reports 0.00 shares beneficially owned and 0.0% of the Class A class. The statement disclaims that most Reporting Persons are beneficial owners of the Class A shares and clarifies organizational relationships among the Blackstone entities.

Positive

• Clear disclosure that each Reporting Person reports 0.00 shares and 0.0% ownership of Class A Common Stock
• Merger conversion terms explicitly stated: each Opco unit converted into 0.4855 LLC units in Viper Energy Partners LLC and 0.4855 Class B shares of Viper Energy, Inc.
• Comprehensive mapping of organizational relationships among Blackstone entities and signatories, improving transparency

Negative

• None.

Insights

Financial Analyst

TL;DR Reporting shows Blackstone-related parties disclose no beneficial ownership of Sitio Class A stock after the merger; conversion mechanics are specified.

The filing is primarily a compliance disclosure: it documents the corporate reorganization resulting from the merger and the conversion formula for Opco units into Viper equity units and Class B shares. The reported 0.00 shares and 0.0% holdings across multiple filing entities indicate no retained Class A exposure by these reporting persons. For analysts, the material item is the conversion ratio (0.4855/0.4855) which determines post-closing economic and governance allocation for former Opco holders.

Corporate Governance Expert

TL;DR Filing clarifies ownership structure and expressly disclaims beneficial ownership by parent and affiliated entities.

The document carefully maps the chain of control among Blackstone entities and includes an explicit disclaimer that most Reporting Persons do not claim beneficial ownership of Class A shares. This is a standard governance disclosure to avoid Section 13(d) implications. The signatures from authorized signatories across entities demonstrate internal coordination and formal acknowledgement of the post-merger capital structure.
