Item 1.01. Entry into a Material Definitive Agreement.

On September 18, 2018, Evergy, Westar, KCP&L and KCP&L Greater Missouri Operations Company, a subsidiary of Evergy (“GMO” and together with Evergy, Westar and KCP&L, the “Borrowers”) entered into a master revolving credit facility with a syndicate of banks (the “Credit Facility”) that provides for maximum borrowings of up to $2.5 billion in the aggregate, including the issuance of letters of credit and swingline loans each up to maximum aggregate amounts of $150 million. So long as there is no default or unmatured default under the Credit Facility, the Borrowers may elect to increase the Credit Facility up to an aggregate principal amount of $750 million by increasing the commitment of one or more lenders who have agreed to such increase.

The Credit Facility matures on September 18, 2023. So long as there is no default or unmatured default under the Credit Facility and subject to the accuracy of the representations and warranties in the Credit Facility as of the extension date, the Borrowers may elect to extend the Credit Facility twice for an additional one year term on each such extension date, subject to lender participation.

The Credit Facility also contains negative covenants, including one that sets the ratio of maximum allowed total indebtedness to total capitalization at 0.65 to 1.00, for each Borrower.
