This combined Current Report on Form 8-K is being filed by Great Plains Energy Incorporated (“Great Plains Energy”) and Kansas City Power & Light Company (“KCP&L”). KCP&L is a wholly-owned subsidiary of Great Plains Energy and represents a significant portion of its assets, liabilities, revenues, expenses and operations. Thus, all information contained in this report relates to, and is filed by, Great Plains Energy. Information that is specifically identified in this report as relating solely to Great Plains Energy does not relate to, and is not filed by, KCP&L. KCP&L makes no representation as to that information.

Section 8 - Other Events

As previously disclosed, on May 29, 2016, Great Plains Energy and Westar Energy, Inc., a Kansas corporation (“Westar”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) by and among Great Plains Energy, Westar and, from and after its accession thereto, GP Star, Inc., a Kansas corporation and a wholly owned subsidiary of Great Plains Energy.

On June 28, 2016, Great Plains Energy, KCP&L and Westar, and certain of their respective affiliates, filed a joint merger application with the Kansas Corporation Commission (“KCC”) seeking approval of the transactions contemplated by the Merger Agreement. After public hearings and briefing on the matter, on April 19, 2017 the KCC issued an order denying the joint merger application and rejecting Great Plains Energy’s application to acquire Westar. We are evaluating the statements made by the KCC at the public meeting and its written order and are considering next steps in this process.
