NEWS RELEASE

Evergy Announces 2023 Results, Declares Quarterly Dividend and Issues 2024 Guidance

KANSAS CITY, MO., February 29, 2024 – Evergy, Inc. (NASDAQ: EVRG) today announced full year 2023 GAAP earnings of $731.3 million, or $3.17 per share, compared to GAAP earnings of $752.7 million, or $3.27 per share, for the full year 2022. Fourth quarter 2023 GAAP earnings were $58.0 million, or $0.25 per share, compared to earnings of $7.5 million, or $0.03 per share, for the fourth quarter of 2022.

Evergy’s full year 2023 adjusted earnings (non-GAAP) and adjusted earnings per share (non-GAAP) were $815.6 million and $3.54, respectively, compared to $853.8 million and $3.71 in 2022. Adjusted earnings (non-GAAP) and adjusted earnings per share (non-GAAP) are reconciled to GAAP earnings in the financial table included in this release.

Fourth quarter 2023 adjusted earnings (non-GAAP) and adjusted earnings per share (non-GAAP) were $61.1 million and $0.27, respectively, compared to $68.6 million and $0.30, respectively, in fourth quarter 2022. Adjusted earnings (non-GAAP) and adjusted earnings per share (non-GAAP) are reconciled to GAAP earnings in the financial table included in this release.

Full year 2023 adjusted earnings (non-GAAP) per share were driven by higher interest expense, higher depreciation and amortization, unfavorable weather compared to the prior year, partially offset by lower operations and maintenance expense, tax items, and higher corporate owned life insurance proceeds.

“In 2023, we advanced our strategic objectives of affordability, reliability and sustainability. The Kansas rate case settlement delivered significant benefits for customers and enhanced our regional rate competitiveness, we achieved a nearly 10% improvement in reliability, and we furthered our responsible energy transition with the addition of the Persimmon Creek wind farm,” said David Campbell, Evergy president and chief executive officer. “Our financial results reflect challenges from the higher interest rate environment, regulatory lag, and mild weather at the end of the year, partially offset by company-wide efforts to manage costs, which resulted in 12% lower adjusted O&M relative to 2022. Looking ahead, we remain laser-focused on operational and financial execution and advancing constructive regulatory policies to help ensure that Kansas and Missouri are competitive in attracting investment capital and well-positioned to capitalize on historic economic development opportunities.”

NEWS RELEASE

Adjusted earnings (non-GAAP) and adjusted EPS (non-GAAP) are intended to aid an investor’s overall understanding of results. Management believes that adjusted earnings (non-GAAP) provides a meaningful basis for evaluating Evergy’s operations across periods because it excludes certain items that management does not believe are indicative of Evergy’s ongoing performance or that can create period to period earnings volatility.

Adjusted earnings (non-GAAP) and adjusted EPS (non-GAAP) are used internally to measure performance against budget and in reports for management and the Evergy Board. Adjusted earnings (non-GAAP) and adjusted EPS (non-GAAP) are financial measures that are not calculated in accordance with GAAP and may not be comparable to other companies’ presentations or more useful than the GAAP information provided elsewhere in this report.
