NEWS RELEASE FOR IMMEDIATE RELEASE

Evergy Announces Upsize and Pricing of Offering of Convertible Notes Due 2027

Kansas City, Mo., December 5, 2023 — Evergy, Inc. (NASDAQ: EVRG) (“Evergy” or the “Company”) announced the pricing of its private offering of $1,200,000,000 aggregate principal amount of its convertible notes due 2027 (the “Notes”) in a private placement to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), reflecting an upsize of $100 million over the previously announced offering size. The Company also granted the initial purchasers of the Notes an option to purchase, within a 13-day period beginning on, and including, the initial closing date of the offering, up to an additional $200,000,000 aggregate principal amount of the Notes. The sale of the Notes to the initial purchasers is expected to settle on or about December 7, 2023, subject to customary closing conditions, and is expected to result in approximately $1,180.9 million in net proceeds to the Company, after deducting the initial purchasers’ discount and estimated offering expenses payable by the Company (assuming no exercise of the initial purchasers’ option to purchase additional Notes).

The Notes will bear interest at a rate of 4.50% per year, payable semiannually in arrears on June 15 and December 15 of each year, beginning on June 15, 2024, and will mature on December 15, 2027, unless earlier repurchased or converted. The initial conversion rate for the Notes is 16.1809 shares of the Company’s common stock per $1,000 principal amount of Notes (which is equivalent to an initial conversion price of approximately $61.80 per share and which represents a premium of approximately 22.5% over the $50.45 per share last reported sale price of the Company’s common stock on December 4, 2023). Prior to September 15, 2027, the Notes may be converted at the option of the holders only upon the occurrence of specified events and during certain periods, and thereafter until the close of business on the business day immediately preceding the maturity date, the Notes may be converted at any time. The Company will satisfy any conversion by paying cash up to the aggregate principal amount of the Notes to be converted and by paying or delivering, as the case may be, cash, shares of the Company’s common stock, or a combination of cash and shares of the Company’s common stock, at its election, in respect of the remainder, if any, of its conversion obligation in excess of the aggregate principal amount of the Notes being converted. The Company may not redeem the Notes prior to the maturity date. The Notes will be senior unsecured obligations of the Company.

The Company intends to use the net proceeds from the offering (i) to repay the $500 million outstanding under the Company’s unsecured term loan facility due 2024, (ii) to repay a portion of its commercial paper borrowings and (iii) for general corporate purposes.

The offer and sale of the Notes are not being registered under the Securities Act, or the securities laws of any other jurisdiction. The Notes may not be offered or sold in the United States except in transactions exempt from, or not subject to, the registration requirements of the Securities Act and any applicable state securities laws.

This press release shall not constitute an offer to sell or the solicitation of an offer to buy the Notes nor shall there be any sale of these securities in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of such jurisdiction. Any offers of the Notes will be made only by means of a private offering memorandum. The Notes and any shares of the Company’s common stock issuable upon conversion thereof have not been registered under the Securities Act or the securities laws of any other jurisdiction and may not be offered or sold in the United States without registration or an applicable exemption from registration requirements. The Notes being offered have not been approved or disapproved by any regulatory authority, nor has any such authority passed upon the accuracy or adequacy of the private offering memorandum.
