Material Changes vs. Prior Period
- Revenue Growth: Operating revenues increased 9.7% to $5.14 billion, driven primarily by authorized rate increases ($406 million) to recover infrastructure investments, acquisitions ($49 million), and organic growth. This was partially offset by an estimated $36 million decrease due to warmer, drier weather compared to 2024.
- Profitability: Net income increased 5.7% to $1.11 billion. Adjusted diluted EPS grew 8.9% to $5.64, reflecting rate implementations offset by higher production, employee, depreciation, and financing costs.
- Capital Investment: Capital expenditures rose 9.5% to $3.13 billion, focused on infrastructure renewal, resiliency, and water quality compliance (including PFAS and lead service line replacements).
- Debt Structure: Short-term debt increased significantly due to higher commercial paper borrowings ($1.59 billion outstanding vs. $880 million in 2024) to fund liquidity needs and capital projects. Long-term debt issuances totaled $1.79 billion in 2025.
Guidance, Outlook, and Material Events
Strategic Transactions
- Essential Utilities Merger: On October 26, 2025, the Company entered into a stock-for-stock merger agreement with Essential Utilities, Inc. Closing is estimated for Q1 2027. The transaction is subject to regulatory approvals and customary conditions. Estimated total merger-related costs are $150 million.
- Nexus Acquisition: Entered into an agreement to acquire regulated water and wastewater systems from Nexus Water Group for approximately $315 million, adding ~47,000 customers. Closing anticipated by August 2026.
Regulatory and Environmental Outlook
- Rate Cases: Significant rate increases were approved in Illinois ($105 million), Missouri ($63 million), and Pennsylvania (pending $169 million request). Pending filings in New Jersey ($146 million) and Pennsylvania ($169 million) seek to recover capital investments.
- PFAS Compliance: The Company estimates a $2 billion capital investment to comply with new EPA PFAS regulations, with compliance required by April 2029. Annual operating expenses for testing and treatment are estimated at up to $50 million starting near the deadline.
- Lead Service Lines: Estimated $1.5 billion investment between 2026 and 2030 to comply with the Lead and Copper Rule Improvements (LCRI).
Risks and Contingencies
- Legal Proceedings: Ongoing litigation includes the Monterey Peninsula Water Supply Project (California), potential condemnation of Monterey system assets, and class actions related to main breaks in West Virginia and Tennessee. The Company has received $159 million in PFAS litigation settlements (net of fees), with $114 million held in escrow pending regulatory approval for customer benefit.
- Forward Sale Agreements: Entered into agreements in August 2025 for the sale of ~8.1 million shares, with settlement expected by December 31, 2026. Estimated net proceeds are $1.13 billion.
Key Facts for Investor Verification
- Merger Closing Conditions: Verify the status of regulatory approvals required for the Essential Utilities merger, particularly from state Public Utility Commissions (PUCs), as failure to obtain these could delay or terminate the deal.
- Rate Case Outcomes: Monitor the approval status and final amounts of pending rate cases in New Jersey, Pennsylvania, and California, which are critical for funding the $46-$48 billion 10-year capital plan.
- PFAS and Lead Compliance Costs: Track actual capital expenditures against the estimated $2 billion (PFAS) and $1.5 billion (Lead) compliance costs to assess potential impacts on future rate requests and cash flow.
- Liquidity Position: Review the utilization of the $2.75 billion revolving credit facility and commercial paper program, noting the increase in short-term debt reliance in 2025.
- Monterey Condemnation: Follow the legal proceedings regarding the potential eminent domain acquisition of Cal Am's Monterey system assets by the Monterey Peninsula Water Management District.
