Item 8.01. Other Events. New Jersey Board of Public Utilities (“NJBPU”) Approval of Settlement in New Jersey-American Water Company, Inc. (“New Jersey American Water”) General Rate Case On September 9, 2026, the NJBPU issued an order (the “Order”) approving without modification the stipulation of settlement (the “Stipulation”) of a general rate case filed on January 16, 2026 by New Jersey American Water, a wholly owned subsidiary of American Water Works Company, Inc. (the “Company”), seeking approximately $146 million of increased annualized water and wastewater revenues, which request was subsequently updated on July 27, 2026, to approximately $145 million. The Stipulation was entered into on August 27, 2026 with the staff of the NJBPU and the New Jersey Division of Rate Counsel. The Order approves a $68 million annualized increase in New Jersey American Water’s water and wastewater revenues, effective as of September 15, 2026, based on (i) an authorized return on equity (“ROE”) of 9.5%, (ii) an authorized rate base of $6.06 billion , (iii) a common equity ratio of 54.0%, and (iv) a long-term debt ratio of 46.0%. The annualized revenue increase is driven primarily by $1.4 billion of incremental capital investments since that last general rate case.
