(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:

•

•

at the effective time of the Viper Pubco Merger (the “Viper Pubco Merger Effective Time”, which was 12:01 a.m., Eastern Time, on August 19, 2025), (A) each share of Former Viper’s Class A common stock, par value $0.000001 per share (“Former Viper Class A Common Stock”), issued and outstanding immediately prior to the Viper Pubco Merger Effective Time (other than certain excluded shares) was cancelled and automatically converted into one share of New Viper Class A Common Stock and (B) each share of Former Viper’s Class B common stock, par value $0.000001 per share (together with the Former Viper Class A Common Stock, the “Former Viper Common Stock”), issued and outstanding immediately prior to the Viper Pubco Merger Effective Time was automatically cancelled and converted into one share of New Viper’s Class B common stock, par value $0.000001 per share (“New Viper Class B Common Stock”);

•

at the Sitio Pubco Merger Effective Time, each award of restricted stock units in respect of Sitio Class A Common Stock that was outstanding immediately prior to the Sitio Pubco Merger Effective Time, whether or not subject in whole or in part to performance-based vesting conditions, vested in full, with any performance goals in respect of any incomplete performance period deemed achieved based on target performance, and was cancelled and converted into the right to receive (i) 0.4855 shares of New Viper Class A Common Stock in respect of each share subject to such restricted stock unit award and (ii) an amount in cash equal to any accrued but unpaid cash-based dividend equivalents;

•

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.

On August 19, 2025, the Mergers were consummated in accordance with the Merger Agreement (the “Closing”). In connection with the Closing, Former Viper changed its name from “Viper Energy, Inc.” to “VNOM Sub, Inc.” and New Viper changed its name from “New Cobra Pubco, Inc.” to “Viper Energy, Inc.”
