We are investigating possible breaches of fiduciary duty and other violations of law by the board of directors of Rattler Midstream LP (“Rattler” or the “Company”) (NASDAQ: RTLR), in connection with the proposed merger of the Company with Diamondback Energy, Inc. (“Diamondback”) (NASDAQ: FANG).  Under the terms of the merger agreement, the Company’s unitholders will receive 0.113 units of Diamondback for each unit of Rattler common unit owned, representing implied per-share merger consideration of approximately $15.08 based upon Diamondback’s May 13, 2022 closing price of $133.43.

Weiss Law is investigating whether (i) Rattler’s board of directors acted in the best interests of Company unitholders in agreeing to the proposed transaction, (ii) the per-unit merger consideration adequately compensates Rattler’s unitholders, and (iii) all information regarding the sales process and valuation of the transaction will be fully and fairly disclosed.
