American States Water Company Announces Final Decision by the CPUC in Its Water Utility General Rate Case Proceeding

American States Water Company (NYSE:AWR) announced that on January 30, 2025, the California Public Utilities Commission ("CPUC") adopted a final decision in connection with the general rate case at AWR's regulated water utility subsidiary, Golden State Water Company ("GSWC").

The final decision in GSWC's general rate case proceeding will set new water rates for the years 2025 –2027. The assigned administrative law judge at the CPUC had issued a proposed decision on November 15, 2024 that adopted a settlement agreement between GSWC and the Public Advocates Office at the CPUC with new rates effective January 1, 2025. The proposed decision also addressed the unresolved issues related to GSWC's requests for certain regulatory mechanisms. Among other things, the proposed decision rejected GSWC's request for the continuation of a sales reconciliation mechanism, which would allow GSWC to adjust its sales forecast throughout the general rate case cycle to address significant fluctuations in consumption. On December 27, 2024, an alternate decision was issued by the assigned Commissioner that instead approved GSWC's request to continue this mechanism. No other material changes were made to the proposed decision. The final decision is consistent in all material respects with the alternate decision issued on December 27, 2024. Subsequent to receiving the final decision, GSWC filed for the implementation of new 2025 rate increases that went into effect on February 1, 2025.
