Dallas, Texas — October 13, 2016 — RSP Permian, Inc. (“RSP” or the “Company”) (NYSE: RSPP) today announced that it has priced an underwritten public offering of 22,000,000 shares of its common stock at $39.75 per share. The offering was upsized to 22,000,000 shares of common stock from the original offering size of 20,000,000 shares of common stock. The Company has granted the underwriters a 30-day option to purchase up to an additional 3,300,000 shares of the Company’s common stock. Total gross proceeds (before the underwriters’ discounts and commissions and estimated offering expenses) will be approximately $874.5 million to the Company. The offering is expected to close on October 18, 2016, subject to customary closing conditions. The Company intends to use the net proceeds from this offering to fund a portion of the previously announced acquisition of Silver Hill Energy Partners, LLC and Silver Hill E&P II, LLC (the “Acquisition”). The offering is not conditioned on the consummation of the Acquisition, and if the Acquisition does not occur, the net proceeds will be used for general corporate purposes, which may include funding a portion of the Company’s 2017 capital budget.
