Exhibit

The Company estimates its Midland Basin footprint to approximate 87,600 net acres, including the pending acquisition of additional leasehold interests announced in early December 2016. The acquisition was funded predominantly with cash proceeds from recent asset divestitures and the issuance to the sellers of 13.4 million shares of SM Energy common stock. The effective date of the transaction is September 1, 2016. The Company intends to operate two rigs on this leasehold position during 2017, starting in the first quarter.
