RSP PERMIAN, INC. SHAREHOLDER ALERT: Former SEC Attorney Willie Briscoe Believes the Acquisition by Concho Resources Inc. May be Unfair to Shareholders

Former United States Securities and Exchange Commission attorney Willie Briscoe is investigating potential claims against the Board of Directors of RSP Permian, Inc. ("RSP") RSPP concerning the acquisition by Concho Resources Inc. CXO. Under the terms of the agreement, valued at approximately $9.5 billion, RSP shareholders will only receive 0.320 shares of Concho common stock for each share of RSP common stock held. The consideration is significantly lower than at least one analyst's estimated value of $69.00.

If you are an affected investor, and you want to learn more about the investigation or if you have information that you believe would be helpful to our investigation of the fairness of the proposed transaction, contact Willie Briscoe at The Briscoe Law Firm, PLLC via email at shareholders@thebriscoelawfirm.com or by calling (888) 809-2750. There is no cost or fee to you.

The investigation centers on whether RSP's Board of Directors is acting in the shareholders' best interests, whether the board considered alternatives to the acquisition, and whether the board has employed an adequate process to review and act on the proposed transaction. Notably, at least one analyst with Yahoo! Finance believes the true inherent value of RSP could be as high as $69.00 per share.
