Lengthy Approval Process Involves Multiple Regulatory Jurisdictions and Stakeholders
The merger requires approval from public utility commissions in every state where the combined company operates. Each state conducts its own independent review examining whether the merger serves the public interest.
American Water expects the approval process to extend through 2026, with closing targeted for the first quarter of 2027. Both companies must also secure shareholder approval through their annual meetings. Essential Utilities scheduled its merger vote for February 2026.
What Will Success of This Utility Merger Mean for Customers and the Water Industry?
If approved, the combination would establish an industry-leading regulated utility positioned to invest heavily in water infrastructure modernization. Combined capital generates increased access to debt and equity markets, allowing faster investment in aging pipe networks and treatment facilities.
American Water projects the merger will support long-term earnings growth of 7-9% for the combined company. Industry experts suggest larger utilities gain efficiencies in operations, technology deployment, and workforce management. However, state regulators will scrutinize rate impacts to ensure customers benefit from operational improvements.
