Filing of Rate Request with the Missouri Public Service Commission (the “MoPSC”) by Missouri-American Water Company (“Missouri American Water”)
On July 1, 2026 , Missouri American Water, a wholly owned subsidiary of American Water Works Company, Inc. (the “Company”), announced that it filed with the MoPSC a request for new water and wastewater rates. The request seeks annualized incremental revenue of approximately $179 million, excluding infrastructure surcharges of approximately $32 million, of which $18 million remains subject to approval. The request is based on a return on equity of 10.50% and a capital structure with an equity component of 50.3% and a long-term debt component of 49.7%. The requested annualized incremental revenue is driven primarily by approximately $1.6 billion of incremental capital investments completed and planned by Missouri American Water from June 2025 through May 2028, the forecasted future test period. Missouri American Water anticipates that new rates will take effect in June 2027. Pursuant to statutory requirements, Missouri American Water will implement subsequent rate adjustments following the conclusion of the future test year based on required reconciliations, subject to regulatory approval.

Exhibit 99.1
Missouri American Water Files Rate Request Driven by Approximately $1.6 Billion in Investments to Provide Safe, Clean, Reliable and Affordable Service
Request supports continued infrastructure investments in water and wastewater
systems serving more than 1.7 million people in 30 counties
ST. LOUIS, MO., July 1, 2026 – Missouri American Water today filed a request with the Missouri Public Service Commission (MoPSC) for new rates to support approximately $1.6 billion in water and wastewater system investments from June 2025 through May 2028. The request reinforces the company's commitment to implementing critical system upgrades and continuing to improve water quality and reliability for its more than 1.7 million people served statewide.
“We strategically plan and invest in our water and wastewater systems to help ensure they continue meeting the needs of our customers and communities,” said Rich Svindland, President of Missouri American Water. “These investments strengthen service reliability and enhance water quality—from treatment to tap—while reflecting our employees’ ongoing commitment to the health and safety of the communities we proudly serve.”
The proposed rate change will support the company's continuing infrastructure investments from June 2025 to May 2028 to modernize and strengthen its water and wastewater systems in communities across Missouri. These investments will include the replacement of approximately 140 miles of aging water and wastewater pipeline, upgrading of storage tanks, wells, pumping stations, hydrants, meters and wastewater plants, as well as ongoing replacement of lead service lines and improvements to treatment facilities to address regulatory requirements, including PFAS and other contaminants of emerging concern.
Investments include:
•St. Louis County: The relocation and replacement of the South Plant intake at a higher elevation mitigates flood risk, while raw water pump replacements, emergency power generation and replacement of aging pump components improve operating efficiency and reduce service disruptions during extreme weather.
•Jefferson City: Construction of a new filter and chemical feed building renews critical infrastructure past its useful life and enhances water quality and treatment efficiency.
•St. Joseph: Water treatment plant expansion including a new clarifier and filters, rehabilitation of treatment units and upgrades to chemical feed system improves service reliability, safety, and efficiency.
•Joplin: Construction of a new carbon feed system, well site treatment upgrades and filter backwash improvements will increase safety and help maintain consistent water quality and service reliability.
•Wastewater Treatment Investments: Treatment equipment upgrade, lift station construction and treatment enhancements will improve treatment reliability and efficiency, while helping to meet environmental compliance.
If the company’s proposed rates are approved as filed with the MoPSC today, the water bill for the average residential customer in St. Louis County using 5,900 gallons per month would increase by approximately $23 per month. The water bill for the average residential customer outside of St. Louis County using 4,500 gallons per month would increase by about $15 per month. The request updates residential wastewater rates to support continued investment with modest increases for lower usage customers and larger adjustments that help align higher-usage and unmetered customers with the cost of service.
Missouri American Water remains committed to affordability and offers programs to assist income-eligible customers, including its H2O Help to Others assistance program, budget billing options and flexible payment plans. More details can be found on the company’s customer service webpage.

The rate request is the first step in an extensive MoPSC review process that can take up to 11 months. Customers will have multiple opportunities to provide input, including submitting written comments and attending public input hearings scheduled by the MoPSC. All rate changes require MoPSC approval. If approved, the company’s new rates could take effect in June 2027.
