Q2 2024 Financial Results

Year-to-Date 2024 Financial Results

As a result of the Q1 2024 adoption of the 2021 California GRC, interim rate relief attributable to 2023 totaling $64.0 million was recognized in 2024 operating revenue, including $18.7 million and $35.4 million that were attributable to the three and six months ended June 30, 2023, respectively.

Liquidity, Financing, and Capital Investment

As of June 30, 2024, Group maintained $82.7 million of cash, of which $45.4 million was classified as restricted, and had additional short-term borrowing capacity of $355 million, subject to meeting the borrowing conditions on the Group and Cal Water lines of credit.

Cal Water Files Infrastructure Improvement Plan for 2024 California General Rate Case; Plans to Invest $1.6 Billion in its California Water Systems in Upcoming Three Years

On July 8, 2024, Group’s largest subsidiary, California Water Service (Cal Water), submitted Infrastructure Improvement Plans for 2025-2027 as part of its triennial GRC filing. The application to the CPUC also proposes a Low-Use Water Equity Program, which would decouple revenue from water sales, to assist low-water-using, lower-income customers.

Cal Water proposes to invest more than $1.6 billion in its districts from 2025-2027, including approximately $1.3 billion of newly proposed capital investments, to support its ability to continue to provide a reliable supply of high-quality water.

To enhance affordability—particularly for low-use and low-income customers, Cal Water’s application proposes a Low-Use Water Equity Program that would decouple revenue from water sales across its regulated service areas. The program is designed to work in conjunction with Cal Water’s proposed progressive, four-tier rate design and sales forecast proposals to keep rates affordable, reinforce conservation goals, and provide the utility an opportunity to recover its authorized revenue requirement in a timely manner.

In its application, Cal Water has proposed to change 2024 rates to increase 2026 total revenue by $140.6 million, or 17.1%. Cal Water also proposes rate increases of $74.2 million, or 7.7%, in 2027; and $83.6 million, or 8.1%, in 2028.

The triennial filing begins an approximately 18-month review process by the CPUC.

Company Hosts Emergency Response Exercises in Hawaii and Responds to the Butte County Thompson Fire

To enhance coordination during emergencies, the Company’s Hawaii subsidiary, Hawaii Water Service (Hawaii Water), hosted representatives from emergency response and regulatory agencies, elected and State offices, utilities, contractors, and other community partners for Community Emergency Operations Center (EOC) exercises in early July on both Maui and the Big Island.

Attendees of the Maui exercise, which included both an emergency response course using the Incident Command System and a hands-on disaster simulation, were Hawaii local and state representatives and representatives from the Maui Police Department, Maui Department of Water Supply, Hawaiian Electric, and the Hawaii Public Utilities Commission. Attendees of the Hawaii island exercise included representatives from Hawaii County Fire, Hawaii Wildfire Management Organization (Firewise), Hawaii County Civil Defense, Community Emergency Response Team (CERT) – Waikoloa, and Hawaii Rural Water Association.

Emergency response training is regularly conducted throughout the Company. In July, when the Butte County Thompson Fire threatened Oroville, Calif., Cal Water activated emergency operations, brought in additional resources to help manage the water system and communicate with customers, and embedded with the Butte County emergency operations center. None of the utility’s assets were impacted during the fire, which burned 3,789 acres over a six-day period.

Company Continues to Pursue Recovery for PFAS Contamination Costs

In April, the U.S. Environmental Protection Agency adopted a new National Primary Drinking Water Regulation to limit certain per- and polyfluoroalkyl substances (PFAS) in drinking water. Under the new regulation, public water systems across the country are required to monitor for these PFAS by 2027 and to comply with applicable maximum contaminant levels by 2029.

Although this regulation faces legal challenges, the Company is proceeding with compliance efforts and believes it is well positioned to comply within the designated timeline. At the same time, it is vigorously pursuing financial recovery from responsible parties. Group has submitted its initial claims in the 3M and DuPont class action settlements and will continue to seek cost recovery wherever it is appropriate to do so.

Separately, the EPA recently designated two of the most common PFAS, specifically PFOA and PFOS, as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA).

ESG Progress is Highlighted in the Company’s New ESG Report

In May, the Company released its 2023 ESG Report and ESG Analyst Download. The ESG Report—which is aligned with recognized reporting frameworks and standards, including the Sustainability Accounting Standards Board Water Utilities & Services Industry Standards, the Recommendations of the Task Force on Climate-Related Financial Disclosures, and the Global Reporting Initiative Standards—details progress made by Group's subsidiaries on the Company's ESG focus areas last year, while the supplemental ESG Analyst Download provides key ESG data and metrics.

This year's ESG Report highlights both ongoing efforts to support Group's ESG strategy and objectives along with significant achievements in 2023, such as how the Company is working to protect the planet, serve customers, and engage the Company’s workforce.
