Item 1.01.      Entry into a Material Definitive Agreement.

On June 29, 2018, 4C Acquisition, LLC (“4CA”) and Navajo Transitional Energy Company (“NTEC”) entered into an asset purchase agreement (the “Agreement”) providing for the purchase by NTEC of 4CA’s 7% interest in Units 4 and 5 (the “Interest”) of the Four Corners Power Plant near Farmington, New Mexico (“Four Corners”). 4CA is a wholly-owned subsidiary of Pinnacle West Capital Corporation (“Pinnacle West”). See “Four Corners - Asset Purchase Agreement and Coal Supply Matters” in Part I, Item 2 of the Pinnacle West/Arizona Public Service Company (“APS”) Quarterly Report on Form 10-Q for the quarter ended March 31, 2018 (the “10-Q”) for information about the contractual and other circumstances leading to NTEC’s purchase of the Interest.

Completion of the purchase is subject to the receipt of approval by the Federal Energy Regulatory Commission, which is currently pending and is expected in the near future. NTEC will purchase the Interest at 4CA’s book value, approximately $70 million, and will pay 4CA the purchase price over a period of four years pursuant to a secured interest-bearing promissory note. In connection with the purchase by NTEC, Pinnacle West will guarantee certain obligations that NTEC will have to the other owners of Four Corners, such as NTEC’s 7% share of capital expenditures and operating and maintenance expenses. Pinnacle West’s guarantee will be secured by a portion of APS’s payments to be owed to NTEC under NTEC’s agreement to supply coal to the Four Corners owners.

The Agreement was signed concurrent with the settlement of a dispute under the coal supply agreement between NTEC and the Four Corners owners. (For additional information about the dispute, see “Four Corners Coal Supply Agreement - Arbitration” in Note 8 of Combined Notes to Condensed Consolidated Financial Statements in the 10-Q.)
