(AWCC), is offering $500,000,000 principal amount of 5.550% Senior Notes due 2033 under its shelf registration.

American Water Works Company, Inc. (AWK), through its finance subsidiary American Water Capital Corp. (AWCC), is offering a new series of unsecured senior notes under its shelf registration. The notes will pay fixed interest semi-annually on April 1 and October 1, beginning April 1, 2027, and will mature on an October 1 date in a future year. AWCC may redeem the notes at its option, including a make-whole redemption prior to a specified Par Call Date and at par thereafter, as described in the offering documents.
The notes rank equally with AWCC’s other senior unsecured debt and are structurally subordinated to secured debt and to obligations of American Water’s operating subsidiaries. A support agreement from American Water Works Company, Inc. functions as a full and unconditional guarantee, but that obligation is effectively subordinated to the liabilities of subsidiaries other than AWCC. AWCC is a financing vehicle that on-lends all long-term debt proceeds to American Water and its regulated utility subsidiaries.
American Water generated $5,140 million of consolidated operating revenues and $1,111 million of net income attributable to common shareholders in 2025, and had $15,991 million of total consolidated debt as of June 30, 2026. As of that date, long-term debt totaled $14,492 million (including $446 million current portion), commercial paper at AWCC was $1,499 million, and AWCC had $78 million of letters of credit outstanding. Risk factors emphasize dependence on subsidiary distributions to service the notes, the ability of subsidiaries to incur additional debt that would be effectively senior, and the possibility of limited secondary-market liquidity for the notes.
