Item 8.01.    Other Events.
Missouri Public Service Commission (the “MoPSC”) Approval of “Black Box” Settlement in Missouri-American Water Company, Inc. (“Missouri American Water”) General Rate Case
On May 3, 2023, the MoPSC issued an order (the “Order”) approving the March 3, 2023 joint “black box” settlement of the general rate case filed by Missouri American Water, a wholly owned subsidiary of American Water Works Company, Inc. (the “Company”). The Order approves a $44.3 million annualized increase in water and wastewater revenues, excluding $50.7 million in previously approved infrastructure surcharges. The new water and wastewater rates are expected to be effective by May 31, 2023. The original filing, made on July 1, 2022, requested a $105.1 million increase in annualized water and wastewater revenues, excluding $40.2 million in previously approved infrastructure surcharges. Subsequent to the original filing, Missouri American Water filed an additional request for recovery of defined infrastructure investments, which adjusted the infrastructure surcharges to $50.7 million, and, in turn, the amount of the incremental annualized revenue in the general rate case decreased to $94.6 million.
The requested annualized revenue increase was driven primarily by $770 million of incremental capital investments since the 2021 general rate case. For purposes of the general rate case, Missouri American Water’s view of its rate base is $2.3 billion, and its view as to its return on equity (“ROE”) and long-term debt ratio (each of which is based on the Order but was not disclosed therein) is 9.75% and 50.0%, respectively, compared to an ROE of 9.55% and long-term debt ratio of 50.0%, each of which was based on Missouri American Water’s view of its 2021 general rate case.
A copy of the press release issued by Missouri American Water on May 3, 2023 to announce the issuance of the MoPSC’s order has been filed as Exhibit 99.1 hereto and is incorporated herein by reference.
