Insights

Securities Analyst

TL;DR Insiders disposed of all holdings in Sitio via merger consideration, eliminating their beneficial ownership.

The filing documents a complete disposition of reported Class A and Class C shares and corresponding partnership units on 08/19/2025 tied to the merger with Viper Energy, Inc. The transaction reduces the reporting parties' post-transaction holdings to zero and is recorded as an S (sale/disposition) code. Holdings were held directly by Source Energy Permian II, LLC and affiliated Source/Oaktree entities are disclosed as indirect managers with disclaimers of beneficial ownership except for pecuniary interest. For investors, this is a technical ownership update reflecting the legal exchange of issuer securities for merger consideration; the Form 4 contains no separate cash sale details or prices.

Corporate Governance Expert

TL;DR The filing shows corporate insiders relinquished equity due to a merger, with layered entity disclosures and disclaimers.

The report lists multiple related reporting entities (Source, Sierra, Source Energy, FIE, and Oaktree-affiliated managers) and explains direct versus indirect holding relationships and disclaimers. It also confirms that each Sitio Royalties OP unit plus a Class C share is exchangeable for one Class A share, and that all reported securities were exchanged under the merger agreement dated June 2, 2025. The disclosure follows Section 16 reporting requirements and clarifies chain-of-ownership but does not provide merger consideration specifics beyond the exchange mechanics.
