Item 2.01 Completion of Acquisition or Disposition of Assets.

On July 19, 2018, Concho Resources Inc., a Delaware corporation (“Concho”), completed its previously announced acquisition of the Company, pursuant to that certain Agreement and Plan of Merger (the “Merger Agreement”), dated as of March 27, 2018, by and among Concho, Green Merger Sub Inc., a Delaware corporation and a wholly-owned subsidiary of Concho (“Merger Sub”), and the Company. Pursuant to the Merger Agreement, Merger Sub merged with and into the Company, with the Company continuing as the surviving corporation and a wholly-owned subsidiary of Concho (the “Merger”).

As a result of the Merger, each share of common stock, par value $0.01 per share, of the Company issued and outstanding immediately prior to the effective time of the Merger (the “Effective Time”) (excluding certain Excluded Shares (as defined in the Merger Agreement)) was converted into the right to receive from Concho 0.320 of a fully-paid and nonassessable share of common stock, par value $0.001 per share, of Concho (“Concho Shares”).

The issuance of Concho Shares in connection with the Merger was registered under the Securities Act of 1933, as amended (the “Securities Act”), pursuant to Concho’s registration statement on Form S-4 (File No. 333-224354), declared effective by the Securities and Exchange Commission (the “SEC”) on June 6, 2018. The joint proxy statement/prospectus (the “Joint Proxy Statement/Prospectus”) included in the registration statement contains additional information about the Merger.

The foregoing description of the Merger and the Merger Agreement and the transactions contemplated thereby is not complete and is subject to and qualified in its entirety by reference to the Merger Agreement, a copy of which was included as Annex A to the Joint Proxy Statement/Prospectus, and is incorporated by reference in this Current Report on Form 8-K.

In connection with the completion of the Merger, the Company notified the New York Stock Exchange (“NYSE”) that each outstanding share of the Company’s common stock was converted into the right to receive Concho Shares and requested that NYSE withdraw the listing of the Company’s common stock. Upon the Company’s request, NYSE filed a notification of removal from listing on Form 25 with the SEC with respect to the delisting of the Company’s common stock. The Company’s common stock ceased being traded prior to the opening of the market on July 19, 2018, and will no longer be listed on NYSE.
