Investor Presentaiton

In Summary • Results were driven by the revenue shortfall in Q1 due to the record wet winter, the temporary absence of regulatory mechanisms and delayed California GRC. We anticipate potential future recognition of these mechanisms would result in additional revenue in a future period. Our 2023 ESG report will be published on May 16. While we await regulatory decisions in California and continue to execute our business and capital plans, our operations teams are focused on the potential for floods and wildfires in the coming months. k CALIFORNIA WATER SERVICE GROUP INVESTING FOR LIFE INVESTOR RELATIONS 17
