American Water and Essential Utilities Agreed to a $63 Billion Merger. A Subsidiary Wants a 14.6% Rate Increase First.
Summary
American Water Works and Essential Utilities announced an all-stock merger in October 2025 with a combined enterprise value of about $63 billion, creating a single regulated water and wastewater company serving about 4.7 million connections across 17 states. Weeks later, on November 14, 2025, American Water's Pennsylvania subsidiary asked state regulators for a $168.7 million annual rate increase, built on a proposed 10.95% return on equity, for a company that employs about 7,000 people to serve roughly 14 million customers nationwide.
What the rate case asks for
Pennsylvania American Water's filing is driven, the company says, by more than $1.2 billion in capital investment completed or planned between June 2025 and mid-2027. Translated into a typical customer's bill, the company itself estimates an increase of about $14 a month for water service, $10 a month for sanitary wastewater, and $20 a month for customers on combined stormwater/wastewater systems.

| Water service | +$14/mo | typical residential customer |
|---|---|---|
| Wastewater service | +$10/mo | typical residential customer |
| Combined stormwater/wastewater | +$20/mo | typical residential customer |
Those are company-wide averages. The PUC's own investigation order reports a much wider range once PAWC's roughly 682,000 water customers and 97,000 wastewater customers are broken out by county: water bills would rise anywhere from $2.73 to $27.77 a month (9.8% to 41.14%), and wastewater bills from $0 to $26.29 a month (0% to 54.14%), depending on which of the utility's many separate rate zones — a legacy of decades spent acquiring small municipal systems — a customer happens to sit in. The request is currently suspended pending an Administrative Law Judge investigation and public hearings; a final PUC decision is due by August 13, 2026.
What the rate case is sized to deliver
American Water doesn't only report the dollar figure to Pennsylvania — it also reports, in its own filings, exactly what return that revenue is built to produce. The company's Form 10-K for fiscal 2025 describes the same Pennsylvania filing this way: "aggregate annualized incremental revenue of approximately $169 million, excluding projected infrastructure surcharges of approximately $19 million... based on a proposed return on equity of 10.95% and a capital structure with an equity component of 55.33%." Regulators can accept, trim, or reject that 10.95% target — Pennsylvania's own past orders for American Water subsidiaries elsewhere have landed closer to 9.6%–9.75% — but the ask itself is a guaranteed number attached to shareholder capital, not a number that fluctuates with how customers use water.

The same company, counted in people
The rate base being expanded and the merger being negotiated both run on the same workforce. As of December 31, 2025, American Water Works reported approximately 7,000 employees company-wide — across all 24 states it serves, not Pennsylvania alone — providing water, wastewater, and related services to about 14 million people. That works out to roughly one employee for every 2,000 people served. Of those 7,000, the company's national benefits agreement, which runs through July 31, 2028, covers about 3,000 union-represented employees; the remaining employees are not covered by that agreement. Net income attributable to shareholders was $1.111 billion in 2025, up from $944 million two years earlier, per the same filing.

If the merger closes as planned — the companies expect that by the end of the first quarter of 2027 — the combined company would serve about 4.7 million water and wastewater connections across 17 states and 18 military installations, under the exchange terms shareholders approved: Essential Utilities holders receive 0.305 shares of American Water for each share they hold, a roughly 10% premium to Essential's pre-deal stock price. That transaction still needs sign-off from state regulators across the combined footprint, including Pennsylvania's PUC — the same commission deciding, separately, how much Pennsylvania customers pay starting this August.
The takeaway
- Two filings, two calendars, one rate base. The merger (expected to close by Q1 2027) and the Pennsylvania rate case (decided by August 13, 2026) are legally separate actions moving on different timelines, but both are funded from — and decided by regulators who oversee — the same regulated utility structure.
- The company states its own target plainly. American Water's filing doesn't just report the dollar amount it's asking Pennsylvania for; it reports the 10.95% return on equity that amount is calculated to produce, a figure regulators can adjust but customers don't vote on.
- The bill and the workforce serving it aren't the same size. A $168.7 million rate request lands on a company that employs about 7,000 people company-wide to serve roughly 14 million customers — and fewer than half of those employees are covered by its national union benefits agreement.
Figures describe a pending 2025 Pennsylvania rate case and a pending merger between American Water Works and Essential Utilities; both remain subject to regulatory approval and could change before final orders are issued. Employee, union-membership, and net-income figures are company-wide as of the periods stated and are not broken out for Pennsylvania alone.

On October 27, 2025, American Water Works and Essential Utilities told shareholders they would combine in an all-stock merger with a pro forma market capitalization of about $40 billion and a combined enterprise value of approximately $63 billion — creating, on paper, the largest regulated water and wastewater utility in the country. Weeks later, on November 14, 2025, American Water's Pennsylvania subsidiary filed a separate document with a different audience: a request to the Pennsylvania Public Utility Commission to raise water and wastewater rates by $168.7 million a year — 14.6% — on the roughly 2.4 million people the subsidiary serves across 37 counties. Neither filing depends on the other, but both draw on the same rate base, the same investor base, and the same regulatory machinery that decides what a captive water customer pays.
