Rattler Midstream LP Investigation

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.
