**SAN JOSE, Calif.,** July 31, 2025 (GLOBE NEWSWIRE) -- California Water Service Group (Group or Company, NYSE: CWT), a leading publicly traded water utility serving California, Hawaii, New Mexico, Washington, and Texas, today reported financial results for the second quarter 2025.

**Financial highlights included:**

&nbsp;&nbsp;&nbsp;&nbsp;· Net income of $42.2 million or diluted earnings per share of $0.71 in Q2 2025; net income of $55.5 million or $0.93 per diluted share
year-to-date (YTD) in 2025

&nbsp;&nbsp;&nbsp;&nbsp;· $119.4 million invested in water system infrastructure during Q2 and $229.5 million YTD in 2025

&nbsp;&nbsp;&nbsp;&nbsp;· 2024 California general rate case (2024 CA GRC) advanced

&nbsp;&nbsp;&nbsp;&nbsp;· Agreement executed to own and operate Silverwood wastewater and recycled water systems

&nbsp;&nbsp;&nbsp;&nbsp;· First installment of PFAS litigation settlement proceeds received totaling $10.6 million, net

&nbsp;&nbsp;&nbsp;&nbsp;· S&P Global credit rating of A+/ Stable affirmed for California Water Service Company (Cal Water)

&nbsp;&nbsp;&nbsp;&nbsp;· 2024 Sustainability Report published highlighting progress on sustainability targets

&nbsp;&nbsp;&nbsp;&nbsp;· 322 <sup>nd</sup> consecutive quarterly dividend declared in the amount of $0.30 per share

According to Chairman, President, and Chief Executive Officer Martin A. Kropelnicki, the Company's solid financial performance reflects continued focus on cost management and affordability while it works through rate proceedings in many of its states.

"I am pleased with our results through the first half of 2025. Our team continues to make headway on our capital delivery plan while maintaining focus on delivering safe, affordable, reliable, water service to our customers," Kropelnicki said. "I am equally pleased with the progress we are making on our 2024 California GRC, which is proceeding on schedule."

**Q2 2025 Financial Results**

&nbsp;&nbsp;&nbsp;&nbsp;· Q2 2025 revenue increased $20.7 million or 8.5% to $265.0 million, compared to revenue of $244.3 million in Q2 2024. Compared to Q2
2024 non-GAAP revenue, Q2 2025 revenue increased $17.9 million or 7.2%.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Rate changes added $23.9 million of revenue.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Customer water usage increased 5.0%, contributing an additional $7.0 million of revenue.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ These were partially offset by $9.4 million of 2021 California GRC revenue related to new rates recorded in Q2 2024 from two regulatory
mechanisms [Interim Rates Memorandum Account (IRMA) and Monterey-Style Water Revenue Adjustment Mechanism (M-WRAM)].

&nbsp;&nbsp;&nbsp;&nbsp;· Q2 2025 operating expenses increased $17.0 million or 8.7% to $213.1 million compared to operating expenses of $196.1 million in Q2
2024. &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Water production costs increased by $7.9 million, primarily due to an increase in wholesale water rates and increased customer usage.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Other operations expenses increased $6.1 million, primarily due to lower bad debt expenses in Q2 2024 from the one-time application
of California state arrearage funds to eligible past due accounts.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Depreciation and amortization increased $3.1 million due to new capital assets placed in service.

&nbsp;&nbsp;&nbsp;&nbsp;· Q2 2025 net income was $42.2 million or $0.71 per diluted share, an increase of $1.6 million or 3.9% compared to Q2 2024 net income
of $40.6 million or $0.70 per diluted share. Compared to Q2 2024 non-GAAP net income, Q2 2025 decreased $0.2 million or $0.02 per diluted
share. The GAAP to non-GAAP difference in Q2 2024 is due to a $1.8 million finalization in Q2 2024 of amounts recorded in Q1 2024 related
to 2023 interim rate relief, net of tax.

**YTD 2025 Financial Results**

&nbsp;&nbsp;&nbsp;&nbsp;· YTD 2025 revenue decreased $46.1 million or 9.0% to $468.9, compared to revenue of $515.0 million YTD in 2024. Compared to YTD 2024
non-GAAP revenue of $427.6 million, YTD 2025 revenue increased $41.3 million or 9.7%.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Rate changes added $45.5 million of revenue.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Customer usage increased 4.0%, contributing an additional $8.7 million of revenue.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ These were offset by $106.4 million change in two regulatory mechanisms (IRMA and M-WRAM) from the 2021 California GRC. This included
$87.5 million of interim rate relief attributable to 2023.

&nbsp;&nbsp;&nbsp;&nbsp;· YTD 2025 operating expenses increased $5.8 million or 1.5% to $394.8 million compared to operating expenses of $389.0 YTD in 2024.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Water production costs increased by $6.7 million, primarily due to an increase in wholesale water rates and increased customer usage.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Other operations expenses increased $8.0 million, primarily due to higher labor costs YTD 2025 and lower bad debt expenses in Q2 2024
from the one-time application of California state arrearage funds in 2024.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Depreciation and amortization increased $6.2 million due to new capital assets placed in service.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Operating expense increases were offset by $16.3 million in lower income taxes due to lower anticipated pre-tax earnings in 2025 compared
to 2024 as a result of the March 2024 decision in the 2021 California GRC.

&nbsp;&nbsp;&nbsp;&nbsp;· YTD 2025 net income was $55.5 million or $0.93 per diluted share, a decrease of 49.8% and $55.0 million or $0.97 per diluted share
compared to YTD 2024 net income of $110.5 million or $1.90 per diluted share. Compared to YTD 2024 non-GAAP net income, YTD 2025 net income
increased 19.4% or $9.0 million and $0.12 per diluted share. The GAAP to non-GAAP difference in YTD 2024 is due to $64.0 million, net
of tax, of 2023 interim rate relief related to the 2021 California GRC recorded YTD in 2024.

**Non-GAAP Financial Information**

As a result of the delayed 2021 California GRC decision, interim rate relief related to 2023, including revenue of $87.5 million and net income of $64.0 million, or $1.09 per share, was recorded in Q1 2024 and finalized in Q2 2024. Non-GAAP financial measures adjust for the impact of 2023 interim rate relief on 2024 results. For more information on these non-GAAP financial measures, see the reconciliation of results and related explanations under "Non-GAAP Financial Measures" below.

**Liquidity, Financing, and Capital Investment**

As of June 30, 2025, Group's cash and cash equivalents totaled $96.1 million, of which $45.6 million was restricted. Group had an additional short-term borrowing capacity of $240 million, subject to meeting the borrowing conditions on its Group and Group subsidiary, Cal Water, lines of credit.

On May 14, 2025, Group entered into an equity distribution agreement to sell shares of its common stock having an aggregate gross sales price of up to $350.0 million from time to time over the next three years under an at-the-market (ATM) equity program. Group did not utilize the ATM during Q2 2025.

On July 10, 2025, Group received a report from S&P Global Ratings in which Cal Water retained its A+/Stable rating. In the S&P report, Cal Water received a business risk rating of "Excellent" and a financial risk rating of "Intermediate."

Group capital investments for the six months ending June 30, 2025, were $229.5 million, up 7.0% compared to June 30, 2024 YTD investments of $214.4 million.

**California 2024 General Rate Case and Infrastructure Improvement Plan**

On July 8, 2024, Cal Water submitted the 2024 CA GRC that included Infrastructure Improvement Plans for 2025-2027. Cal Water proposes to invest more than $1.6 billion in its districts from 2025-2027 to support its ability to provide a reliable supply of high-quality water and enhance system sustainability. In its application, Cal Water proposes to adjust rates to increase total revenue by $140.6 million, or 17.1%, in 2026; $74.2 million, or 7.7%, in 2027; and $83.6 million, or 8.1%, in 2028. Importantly, the application also proposes a Low-Use Water Equity Program that would decouple revenue from water sales to assist low-water-using, lower-income customers.

The triennial rate filing, which was initiated in July 2024, is now in an approximately 18-month long review process leading to a final California Public Utilities Commission (CPUC) decision and is progressing on schedule. Settlement discussions took place during April 2025, and hearings before the Administrative Law Judge (ALJ) occurred in May 2025. After the hearings, the ALJ requested additional information that parties to the proceedings responded to in June 2025. Opening briefs were filed on July 7, 2025, and reply briefs were filed on July 28, 2025. A final law and motion hearing is scheduled for August 5, 2025, at which point the case will be submitted to the ALJ to draft a proposed decision.

**Silverwood Development**

On June 24, 2025, Cal Water signed an agreement with an affiliate of DMB Development to own and operate the wastewater and recycled water systems of Silverwood, a new master-planned, mixed-use community currently under construction in San Bernardino County, California.

Under the agreement, upon completion of the community's wastewater treatment plant, Cal Water will begin serving approximately 500 wastewater connections that will initially be served by the City of Hesperia. At full development buildout, Silverwood is expected to have more than 15,000 customer connections. Cal Water will build and own the wastewater treatment plant and take ownership of the wastewater collection system and recycled water distribution system in phases as they are completed and ready to accommodate new connections. Construction of the wastewater treatment facility for phase one is expected to range between $60.0 million and $70.0 million.

**PFAS Settlement**

The Company is a party to four separate class-action settlements with the following companies: 3M Company; E.I. Du Pont de Nemours and Company (n/k/a EIDP, Inc.), DuPont de Nemours, Inc., The Chemours Company, The Chemours Company FC, LLC, and Corteva, Inc. (collectively, DuPont); Tyco Fire Products LP; and BASF Corporation. These settlements are designed to resolve certain claims for PFAS contamination of drinking water in active public water systems. The Company plans to use settlement proceeds received, net of fees and expenses, to offset capital expenditures required to comply with PFAS drinking water regulations. In May of 2025, the Company received $10.6 million of proceeds, net of legal fees and expenses, from a settlement with 3M Company. This was the first of ten unequal settlement installments that the Company expects to receive from 3M Company. This was the first of ten unequal settlement installments that the Company expects to receive from 3M Company. The second installment is expected to be received from 3M Company in late 2025 and the remaining installments are expected to be received annually thereafter. Proceeds from settlements with DuPont, Tyco Fire Products LP, and BASF Corporation are expected to be received beginning in late 2025.

**2024 Sustainability Report**

In June, Group published its 2024 Sustainability Report, highlighting continued progress across its four key focus areas: protecting the planet, serving customers, engaging the workforce, and governing with integrity. Among the highlights were:

&nbsp;&nbsp;&nbsp;&nbsp;· Reduction of Scope 1 and 2 greenhouse gas emissions by 23.5% from the Company's 2021 baseline and investment of nearly $3.0
million in energy efficiency upgrades.

&nbsp;&nbsp;&nbsp;&nbsp;· 100% compliance with water quality standards and more than 615,000 water tests conducted.

&nbsp;&nbsp;&nbsp;&nbsp;· Donation of more than $1.1 million to community organizations.

&nbsp;&nbsp;&nbsp;&nbsp;· Expansion of employee training by 17%, new Career Pathways program introduced, and expanded supplier oversight and diversity efforts.

**Dividend**

The Group Board of Directors has declared the 322<sup>nd</sup> consecutive quarterly dividend in the amount of $0.30 per common share, which is expected to yield an annual dividend of $1.20 per common share. In addition, in January, the Group Board of Directors declared a one-time special dividend in the amount of $0.04 per common share. The Company has increased its dividend for 58 consecutive years and has a five-year compound annual dividend growth rate of 7.7%.

**Non-GAAP Financial Measures**

The Company's revenue, net income, and diluted earnings per share are prepared in accordance with GAAP and represent amounts reported on filings with the Securities and Exchange Commission. Adjusted revenue, net income, and diluted earnings per share are non-GAAP financial measures representing GAAP balances that, in this earnings release, are adjusted to exclude the effects of 2023 interim rate relief related to the delayed 2021 California GRC decision recorded by the Company in March 2024 and finalized in the second quarter of 2024. These non-GAAP financial measures are provided as additional information for investors and analysts to better assess the Company's 2025 financial performance as compared to 2024 without the impact of the 2023 interim rate relief on 2024 results. Management also uses these non-GAAP financial measures in evaluating the Company's performance. These non-GAAP financial measures may be different from non-GAAP financial measures used by other companies, even when the same or similarly titled terms are used to identify such measures, limiting their usefulness for comparative purposes. Further, these non-GAAP financial measures should be considered as a supplement to the financial information prepared on a GAAP basis rather than an alternative to the respective GAAP measures.
