Business Context and Reporting Period
This Form 8-K Current Report, dated June 5, 2026, is filed by American Water Works Company, Inc. (AWK). The filing details regulatory developments concerning two wholly owned subsidiaries: California-American Water Company ("Cal Am") and Virginia-American Water ("Virginia American Water"). The report focuses on the filing of settlement agreements related to general rate cases in California and Virginia.
Key Financial Metrics and Regulatory Settlements
California-American Water Company (Cal Am)
- Event: Filed a partial settlement agreement with the California Public Utilities Commission (CPUC) regarding a general rate case initiated July 1, 2025.
- Capital Investment Driver: Approximately $750 million in capital investments completed and planned from 2025 to 2028.
- Settled Incremental Annualized Revenue:
- 2027 Test Year: $24 million
- 2028 Escalation Year: $21 million
- 2029 Attrition Year: $22 million
- Company's Revised Proposal: $43 million (2027), $22 million (2028), and $26 million (2029).
- Implementation Date: New rates effective January 1, 2027, pending final CPUC decision.
Virginia-American Water
- Event: Filed a "black box" stipulation of settlement with the Virginia State Corporation Commission (VSCC) regarding a general rate case initiated November 3, 2025.
- Capital Investment Driver: Approximately $115 million in capital investments completed and planned between May 2025 and April 2027.
- Requested vs. Agreed Revenue: Requested $22 million; agreed to a $16 million annualized increase.
- Cost of Capital Terms:
- Return on Equity (ROE): 9.75% (up from 9.70% in the prior rate case).
- Capital Structure Equity Component: 51.79% (up from 45.67% in the prior rate case).
- Interim Rates: Effective May 2, 2026, with refunds applicable if final rates differ.
Material Changes and Pending Issues
Cal Am: The settlement represents a reduction from the Company's revised proposed position for the 2027 test year ($24 million settled vs. $43 million proposed). The primary issue remaining pending is the treatment of Construction Work in Progress (CWIP). If CWIP is excluded from the rate base, incremental revenues for 2027 and 2028 would decrease to $20 million and $19 million, respectively.
Virginia American Water: The agreed revenue increase of $16 million is lower than the requested $22 million. However, the settlement secures a higher ROE and a higher equity component in the capital structure compared to the previous rate case order.
Guidance, Outlook, and Risks
Outlook: The Company anticipates new rates for Cal Am to be implemented on January 1, 2027, subject to final CPUC approval. Virginia American Water's interim rates are already in effect, with final rates pending VSCC review.
Risks and Contingencies:
- Final decisions by the CPUC and VSCC are required to ratify the settlements.
- Resolution of the CWIP issue in the Cal Am rate case could materially reduce revenue.
- Timing of final decisions and rate implementation remains uncertain.
- Specific regulatory risk noted regarding the potential condemnation of Cal Am's water system assets on the Monterey peninsula.
- Unexpected costs, liabilities, or delays associated with the resolution of these rate cases.
Investor Verification Checklist
- Verify the final CPUC decision on the Cal Am partial settlement, specifically the treatment of CWIP.
- Confirm the VSCC's final approval of the Virginia American Water stipulation and the exact final revenue increase.
- Monitor the implementation timeline for Cal Am's new rates effective January 1, 2027.
- Review the impact of the potential condemnation of Cal Am's Monterey peninsula assets on future operations.
- Assess the financial impact of the difference between interim and final rates for Virginia American Water.
