California Water Service Group reported stronger results for the quarter ended June 30, 2026. Operating revenue rose to $308.6 million from $265.0 million, and net income attributable to the company increased to $56.5 million (diluted EPS $0.93) from $42.2 million ($0.71). For the first half of 2026, revenue was $523.2 million and net income $60.5 million. Operating cash flow improved to $113.0 million, while utility capital expenditures reached $276.4 million.
Results were driven by higher authorized rates and regulatory revenues.

The company recognized $15.3 million of Interim Rates Memorandum Account revenue and $9.25 million of previously deferred WRAM revenue. It raised $94.1 million through an at-the-market equity program and received $18.5 million of PFAS-related settlement proceeds.

Results reflect the final decision in the 2024 California General Rate Case, recognized retroactively to January 1, 2026. The decision authorizes company-wide revenue increases of $90.5 million in 2026, $43.2 million in 2027 and $48.9 million in 2028, plus about $1.45 billion of pre-approved infrastructure investments through 2027 and up to $229 million more via the advice letter process. In Q2 2026 the company invested a record $147 million in infrastructure and $276.4 million in the first half, and now anticipates up to $627 million of capital spending in 2026.
