 Sustainability Plan decoupling mechanism, and on May 23, 2025, the CPUC issued its decision denying the application for rehearing. On September 19, 2025, the California subsidiary filed a petition to modify the CPUC order received on December 5, 2024, for its general rate case originally filed on July 1, 2022. The request seeks clarification from the CPUC on the method used to calculate the Conservation Adjustment for Rate Tier Designs (“CART”), specifically for the California subsidiary’s Monterey service area. The CART is a ratemaking mechanism that allows the Company to recover, in subsequent periods, a portion of the impact on operating revenues as a result of implementing customer rates structured to promote conservation usage. On October 20, 2025, the California Public Advocate submitted a response opposing the California subsidiary’s request and stating the request should instead be addressed in the California subsidiary’s pending base rate case. The California subsidiary has requested an opportunity to formally reply. The CPUC will consider both positions, and the California subsidiary expects resolution of the petition to modify later in 2026.

On July 1, 2025, the Company’s California subsidiary filed an application with the CPUC to set new water and wastewater rates in each of its service areas for 2027 through 2029. The application requested an increase of $63 million compared to authorized 2025 revenue, and a total increase in revenue over the 2027 to 2029 period of $111 million. On October 13, 2025, the California subsidiary filed its 100 day update for the same proceeding and updated the request to $62 million compared to authorized 2025 revenue, and a total increase in revenue over the 2027 to 2029 period of $110 million. The requested annualized incremental revenue is driven primarily by
