Offer Letter, dated December 3, 2020

On behalf of Evergy, Inc. (the “Company”), I am pleased to offer you the position of President and Chief Executive Officer of the Company, reporting to the Company’s Board of Directors (the “Board”), working at the Company’s headquarters located at 1200 Main Street in Kansas City, Missouri. Your employment with the Company will commence as soon as practicable, but in no event later than the earlier of February 2, 2021, or three weeks following the release date by your current employer, but not earlier than January 4, 2021. For purposes of this letter (the “Offer Letter”), the date on which your employment with the Company commences is referred to as your “Employment Start Date.” Beginning on your Employment Start Date and at all times during your employment with the Company, you will also serve as a member of the Board. The details of the Company’s offer to you are outlined below:

Inducement Cash Bonus. You will receive an inducement cash bonus of One Million Two Hundred Fifty Thousand Dollars ($1,250,000) (the “Inducement Cash Bonus”), subject to applicable taxes, deductions and withholdings, payable to you on your Employment Start Date. Should you (i) fail to establish your principal residence (or are not under contract for such residence) within the Company’s service territory in the greater Kansas City metropolitan area (as defined by the Company) by July 6, 2021, or (ii) resign from the Company for any reason other than death, “disability” (as defined in the LTIP), or “Good Reason” (as defined in the CIC Agreement, defined below) on or before the first anniversary of your Employment Start Date, you must repay to the Company the Inducement Cash Bonus. No portion of the Inducement Cash Bonus will be subject to any Company clawback policy, as may be in effect from time to time, and may only be forfeited as provided herein.

Inducement Equity Award. You will receive an inducement equity award of restricted stock awards (“RSAs”) granted under the LTIP (the “Inducement Equity Award”). The number of RSAs comprising the Inducement Equity Award will be calculated by dividing Three Million Dollars ($3,000,000) by the closing price of a share of the Company’s stock on the date of your execution of this Offer Letter or, if you execute this Offer Letter on a day during which stock exchanges are closed, the nearest preceding closing price, rounded to the nearest whole share. The Inducement Equity Award shall be granted in three substantially equal RSA awards. The date of grant of your Inducement Equity Award will be your Employment Start Date and such RSA awards shall become vested in accordance with the following schedule, assuming your continued employment by the Company through each applicable vesting date: the first RSA award shall vest on December 31, 2021; the second RSA award shall vest on December 31, 2022; and the third RSA award shall vest on December 31, 2023. The Inducement Equity Award will be subject to the terms and conditions, including any vesting exceptions, in the LTIP and the Company’s standard form of time-based vesting RSA agreement, copies of which have been provided to you; provided however, the Inducement Equity Award shall fully vest in the event of your termination by the Company without Cause or your resignation for Good Reason prior to the applicable vesting dates. In addition to the vesting conditions relating to your continuous employment by the Company, should you fail to establish your principal residence (or are not under contract for such residence) within the Company’s service territory in the greater Kansas City metropolitan area (as defined by the Company) by July 6, 2021, you will forfeit the entire Inducement Equity Award. No portion of the Inducement Equity Award shall be subject to any

other Company clawback policy, as may be in effect from time to time, and may only be forfeited as provided herein. You will be entitled to make a Section 83(b) election, in your sole discretion, with respect to one or more of the Inducement Equity Awards within 30 days following the grant date. It is the intent of the parties that any dividends otherwise payable pursuant to the RSAs shall either be retained and accumulated during the vesting period, or if paid, shall be subject to repayment if the underlying RSA award is forfeited. Any such final determination with respect to dividends shall be reflected in the RSA award agreements. In the event that you make a Section 83(b) election and applicable withholding obligations cannot be met by solely retention of the Inducement Cash Bonus, you will be obligated to use your own funds to meet such shortfall and remit such shortfall amount to the Company in advance of the date you file such Section 83(b) election.

Base Annual Salary. Your initial base annual salary will be One Million Dollars ($1,000,000) per annum, prorated to reflect the portion of the year during which you are an employee of the Company, and will be paid in accordance with the Company’s normal payroll procedures, subject to applicable taxes, deductions and withholdings. Your base annual salary after 2021 is subject to review and increase by the compensation committee of the Board (the “Compensation Committee”).

Your initial target award under the AIP is one hundred twenty-five percent (125%) of your base annual salary (the “Target AIP”). The amount of any future target awards made to you under the AIP will be determined by the Compensation Committee, based on an evaluation of your performance and that of the Company and other evaluative factors relating to comparative levels of pay at the Company’s peer group for similar positions, experience levels and responsibilities, but your Target AIP shall not be less than one hundred twenty-five percent (125%) of your base annual salary. Payment of awards for which you are eligible under the AIP will be subject to the terms and conditions of the AIP and is dependent on performance against pre-established goals and objectives approved annually by the Compensation Committee. Your AIP award for 2021 shall not be subject to proration.

Annual Equity Awards (Long-Term Incentives). You will also be eligible to participate in the Evergy, Inc. Long-Term Incentive Plan (the “LTIP”). Your initial annual equity award under the LTIP, to be granted in 2021, will have a grant date value equal to four hundred twenty-five percent (425%) of your base annual salary (the “Target LTIP”) and will be granted at the same time, and under the same terms, that annual equity awards under the LTIP are granted to other executives of the Company.[1] The value any future annual equity awards made to you will be determined by the Compensation Committee based on an evaluation of your performance and that of the Company and other evaluative factors relating to comparative levels of pay at the Company’s peer group for similar positions, experience levels and responsibilities, but your Target LTIP shall not be less than four hundred twenty-five percent (425%) of your base annual salary. Any annual equity award granted to you will be subject to the terms of the applicable award agreement and the LTIP, including vesting requirements, as approved by the Compensation Committee.

1 At this time, the 2021 LTIP grants are expected to be structured in tranches. One-fourth (1/4) of the equity award will be comprised of time-based restricted stock units (“RSUs”) which will become fully vested on the third anniversary of such RSU’s grant date, assuming your continued employment by the Company through such date. The other three-fourths (3/4) of the equity award will consist of performance-based RSUs that will become vested on the third anniversary of such RSU’s grant date, based on the achievement of certain performance goals established by the Compensation Committee.

Participation in Executive Severance Plan. Effective as of your Employment Start Date, you will participate in the Evergy, Inc. Executive Severance Plan (the “Severance Plan”), pursuant to which, in the event of a “Qualifying Termination” (as defined in the Severance Plan; provided however, such definition shall include your resignation for “Good Reason,” as defined in the CIC Agreement, without the CIC requirement), you will be entitled to the benefits described therein for the Chief Executive Officer. If you experience such a Qualifying Termination during the two-year period beginning on your Employment Start Date, then, in addition to the cash payments you are eligible to receive pursuant to Section 3(a) of the Severance Plan (or any successor provision), you will receive an additional payment equal to the difference between (A) the cash payments that you would have received pursuant to Sections 3(a)(i), (ii), (iii)(C), and (iv) of the CIC Agreement, if any, if you had become eligible for such payments during a “Post-Effective Period” under such agreement and, (B) the cash payments you are eligible to receive under Section 3(a) of the Severance Plan (or any successor provision). Any severance pursuant to this paragraph due to a Good Reason resignation shall be an obligation arising under this Offer Letter though determined by, and subject to the various terms and conditions of, the Severance Plan as if a Qualifying Termination thereunder included a Good Reason resignation. The parties agree that the Severance Plan is not amended, nor needs to be amended, to provide such benefits.
