Missouri Public Service Commission (“MoPSC”) Approval of Settlement in Missouri-American Water Company, Inc. (“Missouri American Water”) General Rate Case
On May 7, 2025, the MoPSC issued an order (the “Order”) approving without modification the stipulation and agreement (the “Stipulation”) with respect to a general rate case filed on July 1, 2024 by Missouri American Water, a wholly owned subsidiary of American Water Works Company, Inc. (the “Company”). The Stipulation was entered into on March 17, 2025, with parties including the staff of the MoPSC and the Office of the Public Counsel. The Order approves a $63.1 million annualized increase in water and wastewater revenues as compared to Missouri American Water’s most recently revised request of $107.4 million. The annualized increase excludes $63.3 million in infrastructure surcharge mechanism revenues currently being collected by Missouri American Water. Missouri American Water’s most recently revised request included an additional request for recovery of defined infrastructure investments, which adjusted the infrastructure surcharges to $63.3 million, and, in turn, decreased the amount of incremental annualized revenue requested (excluding such surcharges) to $107.4 million.
The requested annualized revenue increase was driven primarily by $1.1 billion of capital investments completed and planned by Missouri American Water from January 2023 through May 2025. For purposes of the general rate case, Missouri American Water’s view of its rate base is $3.2 billion, and its view as to its return on equity (“ROE”) and common equity ratio (each of which has been determined based on the Order but was not disclosed therein) is 9.75% and 50.0%, respectively, which is the same ROE and common equity ratio as determined by Missouri American Water based on Missouri American Water’s view of its 2023 general rate case.
A copy of the press release issued by Missouri American Water on May 7, 2025 to announce the issuance of the Order has been filed as Exhibit 99.1 hereto and is incorporated herein by reference. References and links to websites and other information contained in this press release are not provided as active hyperlinks, and the information contained in or accessed through these hyperlinks shall not be incorporated into, or form a part of, this Current Report on Form 8-K.

Increase Driven by $1.1 Billion in Infrastructure Investments
