Kentucky Public Service Commission (“ KPSC”) Issuance of Final Order in Kentucky-American Water Company (“ Kentucky American Water”) General Rate Case

On December 16, 2025, the KPSC issued a final order (the “ Order”) approving the adjustment of base rates requested in a general rate case originally filed on May 16, 2025 by Kentucky American Water, a wholly owned subsidiary of American Water Works Company, Inc. (the “ Company”). The Order approved an $18.2 million annualized increase in water system revenues, excluding infrastructure surcharges of $9.9 million, based on an authorized return on equity (“ ROE”) of 9.70%, authorized rate base of $667.0 million, and a capital structure with a common equity component of 52.26% and a non-equity component of 47.74%, as compared to an authorized ROE of 9.70%, an authorized rate base of $489.4 million, and a capital structure with a common equity component of 52.22% and a non-equity component of 47.78%, all as approved in Kentucky American Water’s last general rate case effective May 3, 2024. The Order also terminated Kentucky-American Water’s Qualified Infrastructure Program (“ QIP”) rider and included the costs and investments of the QIP in approved base rates. The requested annualized revenue increase was driven primarily by approximately $212 million of capital investments completed and planned by Kentucky American Water from February 2025 through December 2026. The new rates are effective as of December 16, 2025.
