Iowa Utilities Commission (“ IUC”) Issuance of Final Order in Iowa-American Water Company (“ Iowa American Water”) General Rate Case

On May 21, 2025, the IUC issued a final order (the “ Order”) approving the adjustment of base rates requested in a general rate case originally filed on May 1, 2024 by Iowa American Water, a wholly owned subsidiary of American Water Works Company, Inc. (the “ Company”). The Order approved a $12.7 million annualized increase in water and wastewater system revenues, excluding infrastructure surcharges of $0.9 million, based on an authorized return on equity (“ ROE”) of 9.60%, authorized rate base of $262.1 million, and a capital structure with a common equity component of 52.57% and a long-term debt component of 47.43%, as compared to an authorized ROE of 9.60%, an authorized rate base of $144.7 million, and a capital structure with a common equity component of 52.28% and a long-term debt component of 47.72%, all as approved in Iowa American Water’s last general rate case effective October 27, 2021. The requested annualized revenue increase was driven primarily by over $157 million of capital investments made and expected to be made by Iowa American Water through March 2026. Interim rates in this case became effective May 11, 2024. The effective date for new rates will be established by the IUC after Iowa American Water files for rates that reflect the Order and the IUC completes its review of that filing.
