Item 5.04	Temporary Suspension of Trading Under Registrant's Employee Benefit Plans.

On May 2, 2018, in accordance with Section 306 of the Sarbanes-Oxley Act of 2002 and Rule 104 of Regulation BTR, Great Plains Energy sent a notice to its directors and executive officers notifying them of a blackout period that (a) Great Plains Energy intends to impose with respect to the Great Plains Energy common stock investment alternative (the Great Plains Energy Stock Fund) for the Great Plains Energy Incorporated 401(k) Savings Plan (the Great Plains Energy Plan) and (b) Westar Energy, Inc. (Westar) intends to impose with respect to the Westar Energy Stock Fund (the Westar Stock Fund) investment alternative in the Westar Energy, Inc. Employees’ 401(k) Savings Plan (the Westar Plan), in each case in connection with the closing of the anticipated Merger referred to below, and certain trading prohibitions that the directors and executive officers will be subject to during the blackout period.

As previously announced, pursuant to an Agreement and Plan of Merger (Merger Agreement) by and among Great Plains Energy, Westar, Monarch Energy Holding, Inc. (Monarch) and King Energy, Inc., a wholly owned subsidiary of Monarch (Merger Sub), and subject to the satisfaction or waiver of certain conditions, (a) Great Plains Energy will merge with and into Monarch with Monarch continuing as the surviving corporation and (b) Merger Sub will merge with and into Westar with Westar continuing as the surviving corporation and as a wholly owned subsidiary of Monarch (collectively, the Merger). Following the closing of the Merger, it is anticipated that (i) the Great Plains Energy Plan will be maintained for Great Plains Energy employees, but the Great Plains Energy Stock Fund investment alternative will be replaced with a Monarch common stock investment alternative, and (ii) the Westar Plan will be maintained for Westar employees, but the Westar Stock Fund investment alternative will be replaced with a Monarch common stock investment alternative. Upon the closing of the Merger, Great Plains Energy employees who currently have investments in the Great Plains Energy Stock Fund in the Great Plains Energy Plan and Westar employees who currently have investments in the Westar Stock Fund in the Westar Plan will each hold shares of Monarch common stock received as consideration in the Merger. As a result, after the closing of the Merger, the blackout to be imposed will also restrict the trading of Monarch common stock held pursuant to the Great Plains Energy Plan and the Westar Plan.

On May 1, 2018, Great Plains Energy received notice from the administrator of the Great Plains Energy Plan that several days prior to the closing of the Merger, the Great Plains Energy Stock Fund under the Great Plains Energy Plan will close to new investments and there will be a limited blackout period during which transactions in Great Plains Energy common stock held in the Great Plains Energy Stock Fund will not be permitted. Similarly, Westar has advised Great Plains Energy that Westar received notice from the administrator of the Westar Plan that several days prior to closing of the Merger, the Westar Stock Fund will close to new investments and there will be a limited blackout period during which transactions in the Westar Stock Fund will not be permitted. In each case, the blackout period is expected to commence several days prior to the closing of the Merger, and could last up to 14 days, including a period of time after the closing of the Merger. At this time, Great Plains Energy is unable to determine the closing date of the Merger and therefore the exact dates for the blackout period cannot be determined. A follow-up communication will be sent to the participants in the Great Plains Energy Plan as soon as the closing date is identified and the exact dates for the blackout period are known.

During the blackout period and for a period of two years after the ending date of the blackout period, holders of Great Plains Energy common stock and Monarch common stock and other interested parties may obtain information about the blackout period, including its actual beginning and ending dates, without charge, by sending a written request to:


•	Prior to the closing of the Merger: Great Plains Energy Incorporated, 1200 Main Street, Kansas City, Missouri 64105, Attention: General Counsel or by calling 816-556-2335.


•	Following the closing of the Merger: Monarch Energy Holding, Inc., 1200 Main Street, Kansas City, Missouri 64105, Attention: General Counsel or by calling 816-556-2335.

A copy of the notice that was sent by Great Plains Energy to its directors and executive officers is attached hereto as Exhibit 99.2 and is incorporated herein by reference.
