The proposed tie-up of two of the largest U.S. water utilities cleared its biggest federal hurdle yet.
American Water and Essential Utilities cleared a key antitrust hurdle as the Hart-Scott-Rodino waiting period for their merger expired Aug 14, moving the deal closer to a close targeted by the end of Q1 2027.
"The expiration of the HSR Act waiting period satisfies one of the conditions to the closing of the pending merger," the companies said in a joint statement.
Regulators in Kentucky, Ohio, and Virginia approved the transaction on April 21, May 13, and June 22, respectively, and the companies reached a settlement in principle in Texas. Shareholders of both companies overwhelmingly approved the deal earlier this year.
The combined company would serve roughly 19.5 million people across 23 states, cementing American Water's position as the largest regulated water and wastewater utility in the U.S. The merger remains subject to customary closing conditions, including remaining regulatory approvals.
The stock-for-stock transaction, structured under a Form S-4 registration declared effective by the SEC on Dec 30, 2025, would fold Essential Utilities' Aqua and Peoples brands — serving about 5.5 million people across nine states — into American Water's footprint of roughly 14 million people in 14 states and on 19 military installations. American Water, founded in 1886 and marking 140 years in 2026, employs about 7,000 people.
Regulatory path narrows
The antitrust clearance removes one of the largest remaining obstacles to the transaction. The HSR Act waiting period expired at 11:59 p.m. EDT on Aug 14 without the Federal Trade Commission or Department of Justice issuing a second request, a common precursor to a formal challenge. The approvals from Kentucky, Ohio, and Virginia, along with the Texas settlement in principle, leave a shrinking list of state regulators still to weigh in before the deal can close.
Integration planning advances
American Water Chief Executive John Griffith told employees on Aug 14 that role selections for the next level of the combined organization have been completed for functions including Legal and Communications & External Affairs, with the remaining functions expected to be finalized in the fall. The changes will not take effect until the merger closes, and all union contracts are being honored, Griffith said.
The deal's completion would reshape the U.S. regulated water sector, where consolidation has accelerated as utilities face rising capital needs for aging infrastructure and stricter environmental rules. If the merger closes as targeted by the end of Q1 2027, the combined company would rank among the largest investor-owned water utilities globally by customer count.
