California Water Service received a final decision on its 2024 General Rate Case and Infrastructure Improvement Plan from the California Public Utilities Commission - CPUC - on April 30, 2026. The Company believes the decision enables Cal Water to invest responsibly in water system infrastructure through 2027 to support its communities and sets Cal Water's revenue and rates to help sustain safe, clean, reliable water service through 2028. The CPUC adopted the proposed decision issued March 13, 2026 with revisions issued on April 29, 2026 (revised PD). The final decision increases Cal Water's company-wide revenues by $90.5 million in 2026, $43.2 million in 2027 (a rate increase of 4.7%), and $48.9 million in 2028 (a rate increase of 5.1%). The differences between approved revenue and rate increases in the PD and the revised PD are primarily attributable to a reduction in authorized capital, some of which is now subject to the CPUC's advice letter process discussed below Cal Water is currently analyzing how the final decision will impact rates in each of its service areas.
