• Sitio Opco units converted into Viper Opco units and New Viper Class B shares, creating continuity of economic interest

Insights

Corporate Transactions Analyst

TL;DR: Insider holdings were converted and canceled under a completed all-equity merger; meaningful ownership reclassification occurred.

The reported transactions stem entirely from the Merger Agreement consummated 08/19/2025. Performance-based RSUs vested and converted at a fixed Exchange Ratio into New Viper equity, and vested partnership units converted into Viper Opco units plus Class B stock equivalents. Class C common shares were canceled without consideration, reducing legacy capital structure complexity. For investors this represents a corporate control change and reallocation of equity from Sitio instruments into New Viper/Viper Opco instruments rather than open-market dispositions.

Securities Governance Specialist

TL;DR: The filing documents internal corporate reorganization of equity holdings tied to the merger, not voluntary insider sales.

The Form 4 clarifies that the reporting person’s changes are consequences of merger mechanics: vesting, conversion, and cancellations prescribed by the Merger Agreement dated 06/02/2025. The cancellation of Class C shares with no consideration is notable from a governance perspective because it eliminates that share class for holders in the transaction. The disclosure is procedural and material to ownership tracking post-merger.
