What Essential Utilities, Inc. told the SEC could break it.
Essential Utilities' results are heavily concentrated in Pennsylvania: its Aqua Pennsylvania subsidiary alone was about 57% of Regulated Water revenue and 72% of that segment's income in 2025, roughly two-thirds of total utility customers are in the state, and about 95% of its natural-gas customers sit in western Pennsylvania — tying it closely to PA regulatory, economic and weather conditions. Its Peoples gas business depends on securing enough gas supply, interstate pipeline capacity and storage to meet peak demand, relying on third-party interstate sources and FERC-regulated pipelines. And its water revenue is sensitive to weather and consumption — a 0.5% drop in residential water use would cut annual residential water revenue by about $3.7 million — amid ongoing conservation pressure.

In its own words
What could break it.
Geographic concentration
- heavy Pennsylvania concentration (Aqua PA = 57% of water revenue/72% of income; gas 95% western PA)high
Essential Utilities is concentrated in Pennsylvania — subsidiary Aqua Pennsylvania alone was ~57% of Regulated Water revenue and ~72% of segment income in 2025, ~66% of total utility customers are in PA, and ~95% of natural-gas customers are in western Pennsylvania — making results highly dependent on PA regulatory, economic and weather conditions.
“One of our largest operating subsidiaries, Aqua Pennsylvania, Inc., or Aqua Pennsylvania, accounted for approximately 57% of operating revenues and approximately 72% of income for our Regulated Water segment in 2025.”

Supplier concentration
- natural-gas supply and interstate pipeline/storage capacity dependence (Peoples)medium
Essential's Peoples natural-gas business must acquire sufficient gas supply, interstate pipeline capacity and storage to meet peak/seasonal demand, relying on third-party interstate sources and FERC-regulated interstate pipelines to transport gas to its distribution system — exposing it to supply, capacity and transportation disruption.
“We are responsible for acquiring sufficient natural gas supplies, interstate pipeline capacity and storage capacity to meet current and future customers' peak, annual and seasonal natural gas requirements. We rely on third-party service providers, as we purchase a portion of our natural gas supply from interstate sources and rely on interstate pipelines to transport natural gas to our distribution system.”

Other disclosures
- weather/consumption sensitivity and conservation-driven volume declinelow
Essential's water revenue is sensitive to weather and consumption patterns — a 0.5% decrease in residential water consumption would cut annual residential water revenue ~$3.7M (partly offset by lower chemical/power production costs) — and ongoing conservation/water-saving-device adoption pressures volumes; revenue is also seasonally concentrated in Q2/Q3.
“It is estimated that, in the event we experience a 0.5% decrease in residential water consumption, it would result in a decrease in annual residential water revenue of approximately $3,700,000, which would likely be partially offset by a reduction in incremental water production expenses such as chemicals and power.”
