Two States Down: American Water's $20B Merger Rolls On

Ohio approved the American Water Works and Essential Utilities merger, the second major state win for a $20.24B deal targeting an early-2027 close

15 Jun 2026

Ohio regulators approved the American Water Works and Essential Utilities merger on May 14, 2026, clearing another critical threshold for a $20.24 billion all-stock deal set to redraw US water infrastructure. Kentucky had already signed off on April 21. Back-to-back state approvals signal real regulatory confidence in the deal's public interest argument.

The combined company will serve 4.7 million water and wastewater connections across 17 states, carrying a rate base of $29.3 billion. At that scale, the merged utility becomes one of the largest regulated water operators in American history. Aging pipe networks, treatment upgrades, and drought resilience projects across two dozen communities now have a better-funded advocate.

John Griffith, President and CEO of American Water, called the transaction good for customers and another example of the execution of the company's core growth strategy. That framing matters. Rather than opportunistic deal-making, each state clearance narrows closing risk and adds a layer of certainty that investors have been watching for.

Consolidation has been building pressure inside a traditionally fragmented utility landscape for years. A combined rate base approaching $30 billion will pull fresh attention from infrastructure funds and institutional allocators.

Pennsylvania and other key states are expected to render decisions before the end of 2026, and each forthcoming approval will sharpen the picture of what a reshaped American water market can deliver for communities, investors, and the environment alike.
