Item 2.01

On August 24, 2022, pursuant to the terms of the previously disclosed Agreement and Plan of Merger (the “Merger Agreement”) by and among Rattler, Diamondback Energy, Inc., a Delaware corporation (“Diamondback”), Rattler Midstream GP LLC, a Delaware limited liability company and the general partner of Rattler (the “General Partner”), and Bacchus Merger Sub Company, a Delaware corporation and wholly owned subsidiary of Diamondback (“Merger Sub”), Merger Sub merged with and into Rattler (the “Merger”), with Rattler as the surviving entity in the Merger.

Pursuant to the terms and conditions of the Merger Agreement, at the effective time of the Merger (the “Effective Time”), each issued and outstanding publicly held common unit representing a limited partner interest in Rattler (each, a “Common Unit”) (other than any Common Units owned by Diamondback and its subsidiaries) (each, a “Public Common Unit”) was converted into the right to receive 0.113 (the “Exchange Ratio”) of a share of common stock, par value $0.01 per share (“Common Stock”), of Diamondback (the “Merger Consideration”). At the Effective Time, (a) Diamondback E&P LLC, a wholly owned subsidiary of Diamondback (“E&P”), continued as a Limited Partner (as defined in the Merger Agreement) of Rattler and a holder of all of the outstanding Class B units in Rattler, (b) by virtue of the Merger, Diamondback was admitted as a Limited Partner of Rattler and a holder of all of the outstanding Common Units in Rattler, (c) the General Partner continued as the general partner of Rattler, and (d) Rattler (as the surviving entity after the Merger) continued without dissolution as a limited partnership.

In addition, on August 24, 2022, in connection with the completion of the Merger, the Partnership terminated the Rattler Midstream LP Long Term Incentive Plan (the “Rattler LTIP”). Pursuant to the terms and conditions of the Merger Agreement, at the Effective Time, each Partnership Phantom Unit (as defined in the Merger Agreement) that was outstanding immediately prior to the Effective Time was converted into an award of Parent RSUs (as defined in the Merger Agreement), was converted into an award of Parent RSUs (as defined in the Merger Agreement), as adjusted by the Exchange Ratio, and otherwise on the same terms and conditions as were applicable to the corresponding Partnership Phantom Units, including any payment timing provisions and distribution equivalent rights, as applicable.

Pursuant to the Merger Agreement, Diamondback issued approximately 4.4 million shares of Diamondback Common Stock to the holders of the Public Common Units as the Merger Consideration, as described above.

The foregoing summary of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Merger Agreement, a copy of which is filed as Exhibit 2.1 to Rattler’s Current Report on Form 8-K filed with the Securities and Exchange Commission (“SEC”) on May 16, 2022, which agreement is incorporated herein by reference.
