Insights

Financial Analyst

TL;DR: Director disposed of all Sitio Class A shares as part of an all-equity merger; insider ownership in Sitio is now zero.

The Form 4 documents a non-sale disposition of 68,675 Sitio Class A shares by director Claire Harvey dated 08/19/2025, occurring through the Merger Agreement with New Viper. The filing clarifies the corporate transaction mechanics: Pubco Mergers and the downstream merger of operating partnerships resulted in conversion of deferred restricted stock units into New Viper Class A shares at a 0.4855 exchange ratio. This report only records the disposition of Sitio securities and does not reflect any separate market sales by the reporting person. For investors, the filing confirms completion of the specified merger steps and the equity conversion terms disclosed.

Corporate Governance Expert

TL;DR: Filing confirms merger closing and vesting/cancellation of Sitio RSUs with conversion into New Viper equity.

The disclosure is procedural and compliant with Section 16 reporting: it records the automatic vesting and cancellation of deferred restricted stock units upon effectiveness of the Sitio Pubco Merger and the conversion mechanics into New Viper shares. The reporting person’s Sitio Class A beneficial ownership is reported as zero post-transaction, reflecting the corporate reorganization rather than an open-market disposition. The Form 4 serves as confirmation of transaction execution and the equity treatment described in the Merger Agreement.
