 Company’s California subsidiary’s general rate case originally filed on July 1, 2022. Incorporating the then currently effective return on equity of 10.20%, the decision provides incremental annualized water and wastewater revenues of $21 million in the 2024 test year, and an estimated $16 million in the 2025 escalation year and $16 million in the 2026 attrition year. The 2024 rates were implemented retroactively to January 1, 2024. In addition, the CPUC denied the California subsidiary’s proposed Water Resources Sustainability Plan decoupling mechanism but approved continuation of its currently effective Annual Consumption Adjustment Mechanism. On December 12, 2024, the California subsidiary filed an application for rehearing of the CPUC’s denial of the proposed Water Resources 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.

Pending General Rate Case Filings

On August 1, 2025, the Company’s Maryland subsidiary filed a general rate case requesting approximately $3 million in annualized incremental revenues, which is based on a proposed return on equity of 10.64% and a capital structure with an equity component of 52.32%. The requested annualized incremental revenue is driven primarily by approximately $22 million of capital investments completed by the Maryland subsidiary from February 2019 through April 2025. The filing must be approved by the Public Service Commission of Maryland, and if approved, it is anticipated that
