American Water Works Company, Inc. 8-K

What Happened
American Water Works Company, Inc. (AWK) announced that the West Virginia Public Service Commission (WVPSC) issued an amended order on March 5, 2026 approving a base rate adjustment for its subsidiary West Virginia American Water. The order authorizes an annualized increase of $20.5 million in water and wastewater system revenues (excluding previously recovered infrastructure surcharges of $12.7 million) and the new rates became effective March 1, 2026. The WVPSC authorized a return on equity (ROE) of 9.8% with a capital structure of 51.0% common equity and 49.0% debt. West Virginia American Water states its view of the authorized rate base is approximately $1.1 billion.

Key Details

• Annualized revenue increase approved: $20.5 million (excludes $12.7 million in previously recovered infrastructure surcharges)
• Authorized ROE: 9.8%; capital structure: 51.0% equity / 49.0% debt
• Company’s view of authorized rate base: ~ $1.1 billion
• Capital investments driving the increase: approximately $239 million in water and wastewater system investments since the prior rate case through February 2026
• New rates effective: March 1, 2026; press release filed as Exhibit 99.1 to the 8-K

Why It Matters
Regulatory approvals that raise allowed rates generally increase utility revenues and can improve cash flow and earnings in later periods; here, the $20.5M annualized increase reflects recovery of significant capital investments. The approved ROE and capital structure determine how much revenue West Virginia American Water can collect to cover costs and earn a regulated return. The filing does not quantify the impact on American Water Works’ consolidated results beyond these figures, but investors should view this as a positive regulatory outcome for the West Virginia utility segment.
