[8-K] AMERICAN STATES WATER CO Reports Material Event

Rhea-AI Filing Summary

American States Water Company, through its subsidiary Golden State Water Company (GSWC), announced that the California Public Utilities Commission approved a one-year deferral of GSWC’s next cost of capital application. GSWC was scheduled to file this application on May 1, 2026, but the date has been postponed to May 1, 2027, with a corresponding effective date of January 1, 2028. The current Water Cost of Capital Mechanism will remain in place during the deferral period.

GSWC’s currently authorized rate of return on rate base is 7.93%, which will continue through December 31, 2027. This is based on a return on equity of 10.06%, an embedded cost of debt of 5.1%, and a capital structure consisting of 57% equity and 43% debt. The decision effectively keeps GSWC’s existing capital cost assumptions and earnings framework stable for an additional year.

Insights

Regulated utilities and rate-making analyst

CPUC deferral extends GSWC’s current 7.93% authorized return through 2027.

The CPUC’s decision allows Golden State Water Company to delay its next cost of capital application from May 1, 2026 to May 1, 2027, with new terms to take effect on January 1, 2028. During this period, the existing Water Cost of Capital Mechanism stays in force, and the current authorized rate of return framework remains unchanged.

GSWC keeps a 7.93% authorized rate of return on rate base through December 31, 2027, built from a 10.06% return on equity and 5.1% embedded cost of debt, with a 57% equity and 43% debt capital structure. For a regulated utility, this provides clarity on allowed earnings and financing assumptions over the next two years.

Actual financial outcomes will still depend on GSWC’s ability to earn its authorized return through operational performance and on any future CPUC determinations after the deferred filing becomes effective on January 1, 2028.
