28 Coal Generation ▪ Since 2018, we have retired nearly 2,500 MW of fossil fuel generation ▪ Retirements planned: ▪ Oak Creek Units 7-8: 611 MW (targeting end of 2027)* ▪ Weston Unit 3: 328 MW (expected end of 2031) ▪ Enhancing fuel flexibility (gas blending) at Oak Creek Power the Future units and Weston Unit 4** ▪ Evaluating the future of Columbia Units 1 and 2 ▪ Exploring conversion of both units to natural gas ▪ By end of 2030, we expect to use coal only as a backup fuel. We plan to eliminate coal as an energy source by end of 2032 *The decision to keep the Oak Creek units available will better position us to serve customers with safe, reliable and affordable energy on the hottest and coldest days of the year. The Oak Creek units will serve as a bridge until new dispatchable generation begins coming online, which is expected in late 2027. **Filed for acquisition of an additional 165 MW of Weston 4 for an estimated investment of $150 million. Pending regulatory approval.
29 * We have paused our near-term reduction goals due to a combination of factors, including tightened energy supply requirements in the Midwest power market and the need to serve our customers with reliable and affordable energy. However, our long-term goal to achieve net carbon neutral electric generation by 2050 remains intact, aligned with global emissions pathways aimed at limiting warming to 1.5°C.

Adjusted earnings per share exclude, as applicable, (1) a one-time reduction in income tax expense related to a revaluation of our deferred taxes as a result of the Tax Cuts and Jobs Act of 2017; (2) costs related to the acquisition of Integrys Energy Group; (3) the results of operations of Integrys and its subsidiaries; (4) the additional shares of WEC Energy Group common stock that were issued as part of the acquisition; (5) a non-cash charge related to the ICC’s disallowance of certain capital costs; (6) losses associated with the ICC disallowance related to its review of the 2016 Qualifying Infrastructure Plant (QIP) capital investments under the QIP rider; and (7) a charge reflecting an agreement on the terms of a proposed settlement PGL and NSG reached with the Illinois Attorney General that, if approved by the ICC, would resolve all open Illinois rider reconciliation proceedings. None of these items are indicative of WEC Energy Group’s operating performance. Therefore, WEC Energy Group believes that the presentation of adjusted earnings per share is relevant and useful to investors to understand the company’s operating performance. Management uses such measures internally to evaluate the company’s performance and manage its operations. **2024 adjusted earnings per share does not add due to rounding.
