CALIFORNIA WATER SERVICE GROUP ANNOUNCES

2023 Earnings for Year and Fourth Quarter

SAN JOSE, CA – California Water Service Group (NYSE: CWT) (“Company” or “CWT”) today announced 2023 full year net income attributable to CWT of $51.9 million and diluted earnings per share of $0.91 for 2023, as compared to net income attributable to CWT of $96.0 million and diluted earnings per share of $1.77 for 2022.

The $44.1 million decrease in net income was primarily due to the delayed final decision from the California Public Utilities Commission ("CPUC") on California Water Service Company’s (“Cal Water”) pending 2021 General Rate Case (“2021 GRC”) to set new revenue, rates, and regulatory mechanisms. The 2021 GRC was originally scheduled to be completed on December 31, 2022 with new rates effective on January 1, 2023. On January 24, 2024, the assigned CPUC Administrative Law Judges (“ALJs”) issued a Proposed Decision (“PD”) on the fully litigated 2021 GRC, and concurrently, the assigned CPUC Commissioner issued an Alternate Proposed Decision (“APD”) opposing and modifying certain decisions made by the ALJs. The PD issued by the ALJs was more closely aligned to Cal Water’s requested revenue requirement whereas the APD issued by the assigned Commissioner was more closely aligned to the Public Advocates’ requested revenue requirement. On February 13, 2024, Cal Water filed a request to change several elements in the PD and APD, including correction of possible technical issues. We are unable to determine which of the two proposed decisions will be adopted by the CPUC, or if a second alternate proposed decision will be issued. As a result of the uncertainty regarding the decision that will ultimately be made by the CPUC, we are unable to reasonably estimate the impact on 2023 operating revenue and expenses. Once approved by the CPUC, the 2021 GRC cumulative adjustment plus interest, which is retroactive to January 1, 2023, will be recorded.

Financial Results for 2023

Net income was positively impacted by increases of $18.4 million in income tax benefit and $12.1 million in net other income, which were partially offset by operating expense increases of $3.2 million in water production, $9.5 million in administrative and general, $6.6 million in depreciation and amortization, and $5.5 million in financing costs.

Operating revenue in 2023 was $794.6 million, a $51.8 million decrease from 2022 operating revenue of $846.4 million. The decrease was primarily due to a $66.9 million decrease in Water Revenue Adjustment Mechanism (WRAM) and Modified Cost Balancing Account (MCBA) revenue as these mechanisms concluded on December 31, 2022, a $23.1 million decrease in customer usage, and a $7.7 million revenue decrease from an increase in deferred revenue, which was partially offset by rate increases of $30.7 million, revenue increases from new customers of $6.7 million, and an increase in accrued unbilled revenue of $3.5 million. 2023 operating revenue does not include rate relief tracked in the Interim Rates Memorandum Account (IRMA) or any benefit of the proposed Monterey-Style Water Revenue Adjustment Mechanism (MWRAM) and Drought Response Memorandum Account (DREMA) due to the delay in CPUC approval of our 2021 GRC.

Total operating expenses in 2023 were $717.5 million, a $1.3 million decrease from 2022 operating expenses of $718.8 million.

Water production costs increased $3.2 million, or 1.0%, to $288.5 million in 2023 compared to the prior year. The increase in water production costs was primarily attributable to rate increases in purchased power and pump taxes.

Administrative and general expenses increased $9.5 million, or 7.2%, in 2023 compared to 2022. The increase was mostly due to increases of $9.0 million in employee wages and $1.2 million in employee benefit costs, which was partially offset by a $1.8 million decrease in uninsured loss costs.

Other operations expenses decreased $3.7 million, or 3.2%, to $112.5 million compared to 2022. The decrease was due mainly to a $6.3 million decrease in costs associated with an increase in deferred revenue, a $2.2 million decrease in conservation expenses, and a $1.7 million decrease in bad debt costs, which was partially offset by a $3.6 million increase in labor costs and $1.4 million increase in water quality testing costs.

Maintenance expense was $32.0 million in 2023 and $31.7 million in 2022. The $0.3 million increase was due to increases in reservoir, tank, well, and pumping equipment repairs.

Depreciation and amortization increased $6.6 million, or 5.8%, to $121.2 million in 2023 primarily due to utility plant placed in-service in 2022.

Income tax benefit increased $18.5 million to $15.2 million compared to 2022. The increase in 2023 was primarily from a decrease in pre-tax operating income due to the delay in the regulatory approval of the 2021 GRC.

Property and other taxes increased $1.2 million, or 3.4%, to $36.3 million, due mostly to an increase in our assessed property values for utility plant placed in service during the year.

Net other income increased $12.1 million, or 101.4%, to $24.1 million in 2023 compared to 2022. The increase was primarily due to a $12.1 million increase in unrealized gains on certain non-qualified benefit plan investments due to market conditions, $5.7 million increase in other components of net periodic benefit credit, and a $1.4 million increase in allowance for equity funds used during construction, which was partially offset by a $2.8 million decrease in non-regulated revenue and $5.3 million increase in income tax expense.

In 2023, net interest expense increased $5.5 million, or 12.4%, to $49.8 million compared to 2022. The increase was due mostly to higher short-term borrowing rates and higher outstanding borrowings on our short-term credit facilities.

According to Chairman and Chief Executive Officer Martin A. Kropelnicki, the Company achieved several positive outcomes in 2023, despite the continued California 2021 GRC regulatory delays.

“The continued delay in Cal Water’s 2021 GRC clearly had an adverse impact on full year 2023 earnings results. I am hopeful the issuance of the PD and APD on January 24, 2024 will result in a final decision during the first half of 2024. While the continued delay coupled with inflation was challenging, there are other updates to report at year-end:

The CPUC postponed Cal Water’s Cost of Capital filing to May 1, 2025. As a result, Cal Water’s authorized return on equity will be 10.27% in 2024, and in 2025 it will be 10.27% plus or minus any changes from the Water Cost of Capital Adjustment Mechanism.

The Company invested $383.7 million in infrastructure improvements in 2023, which was a 17.1% increase from the same period last year. We continue to invest diligently in our water system infrastructure so that we are positioned to provide reliable quality service to our customers and adapt to the effects of climate change.

Our efforts to reduce customer monthly bills include requesting $83.0 million from the State of California Water Arrearages Payment Program in November 2023 to pay residential and commercial customer delinquent and uncollected account balances. Our request is pending approval.

We remain focused on the ESG topics that we believe are most important to our business and to our key stakeholders, and we are proud of the significant progress made in 2023 in the areas of climate change, affordability, infrastructure investment, and sustainability. The details of our accomplishments will be reported in our 2023 ESG Report, which we expect to publish in May 2024.

We declared our 316^th consecutive quarterly dividend and increased the Company’s 2024 annual dividends by 7.7%.

The bottom line, we expect the California regulatory delay to be resolved soon, and we remain laser focused on executing our strategy and serving our customers,” Kropelnicki said.

Fourth Quarter 2023 Results

For the fourth quarter of 2023, net income attributable to CWT was $30.1 million and diluted earnings per share was $0.52 compared to a net income attributable to CWT of $19.6 million and diluted earnings per share was or $0.35 for the fourth quarter of 2022. The $10.6 million increase was primarily due to a $12.3 million revenue increase from a decrease in deferred revenue, $11.2 million increase in income tax benefit, and a $2.8 million increase in net other income, which was partially offset by expense increases of $6.2 million in water production expenses, $5.3 million in employee wages, $3.4 million in depreciation and amortization, and $1.2 million in financing costs.

Results for the fourth quarter of 2023 were negatively impacted by the delayed decision on Cal Water’s pending 2021 GRC to establish new revenue, rates, and regulatory mechanisms.

Operating revenue for the fourth quarter increased $13.6 million, or 6.8%, to $214.5 million primarily due to rate increases of $13.8 million, an increase of $12.3 million in revenue from a decrease in deferred revenue, an increase in customer usage of $3.3 million, and an increase in accrued unbilled revenue of $2.1 million, which was partially offset by a decrease in WRAM and MCBA balancing account revenues of $18.1 million.

Total operating expenses for the fourth quarter increased $4.6 million to $179.3 million. The increase was mainly due to increases of $6.2 million in water production expenses, $5.3 million in employee wages, $3.4 million in depreciation and amortization, and $1.2 million in financing costs, which was partially offset by an $11.2 million increase in income tax benefits.

Income tax benefit for the fourth quarter of 2023 increased $11.2 million to $13.8 million compared to the fourth quarter of 2022. The increase was primarily from a decrease in pre-tax operating income due to the delay in the regulatory approval of the 2021 GRC.

In the fourth quarter of 2023, net other income increased $2.7 million to $7.0 million from $4.3 million in the fourth quarter of 2022. The fourth quarter increase was mostly due to a $2.0 million increase in unrealized gains on non-qualified benefit plan investments and a $2.5 million increase in other components of net periodic benefit credit.

Net interest expense in the fourth quarter of 2023 increased $1.2 million, or 11.2%, to $29.9 million compared to the same period in 2022, primarily due to increases in short-term borrowing rates and higher outstanding borrowings on our short-term credit facilities.

Liquidity and Financing

CWT’s liquidity remains strong. As of December 31, 2023, CWT maintained $85.0 million of cash, of which $45.4 million was classified as restricted, and had additional short-term borrowing capacity of $420.0 million, subject to meeting the borrowing conditions on the CWT and Cal Water lines of credit. CWT’s At-the-Market equity program and Employee Stock Purchase Program provided cash of $115.1 million in 2023. Cal Water requested $83.0 million from the State of California Water Arrearages Payment Program in November 2023 to pay residential and commercial customer delinquent and uncollected account balances during the period from June 16, 2021 to December 31, 2022. Our request is pending approval. CWT’s customer accounts receivable balances more than 60 days as of December 31, 2023 was $15.5 million, a decrease of $2.1 million compared to customer accounts receivable balances more than 60 days as of December 31, 2022.

CWT’s capital investments in 2023 was $383.7 million which was a 17.1% increase from the same period last year.

On January 25, 2024, the Board of Directors increased the quarterly cash dividend by 7.7% and approved a quarterly cash dividend of $0.28 per share of common stock.

INVESTOR RELATIONS The $44.1 million decrease in net income in 2023 compared to the prior year, was primarily due to the delayed final decision from the California Public Utilities Commission (“CPUC”) on California Water Service Company’s (“Cal Water”) pending 2021 General Rate Case (“2021 GRC”). In January 2024, the assigned CPUC Administrative Law Judges (“ALJs”) issued a Proposed Decision (“PD”) on the fully litigated 2021 GRC, and concurrently, the assigned CPUC Commissioner issued an Alternate Proposed Decision (“APD”) opposing and modifying certain decisions made by the ALJs. The PD issued by the ALJs was closer aligned to Cal Water’s requested revenue requirement where as the APD issued by the assigned CPUC Commissioner was closer aligned to the Public Advocates’ requested revenue requirement. We are unable to determine which of the two proposed decisions will be adopted by the CPUC, or if a second alternate proposed decision will be issued by the CPUC. As a result of uncertainty regarding the decision that will ultimately be made by the CPUC, we are unable to reasonably estimate the impact on 2023 operating revenue and expenses.

INVESTOR RELATIONS California 2021 General Rate Case Update On January 24, 2024, the assigned CPUC ALJs issued a PD on the fully litigated 2021 GRC, and concurrently, the assigned CPUC Commissioner issued an APD opposing and modifying certain decisions made by the ALJs. On February 13, 2024, Cal Water completed a CPUC filing. In our filing, Cal Water stated support for the ALJs PD, recommended significant changes to the APD, and requested changes to several elements in the PD and APD including correction of possible technical issues. The earliest the CPUC can deliberate on the PD and APD is March 7, 2023. On February 20, 2024, Cal Water completed a CPUC filing to explain Cal Water’s disagreements with certain comments by the Public Advocates on the PD in their February 13, 2024 CPUC filing. 16

INVESTOR RELATIONS California 2021 General Rate Case Update, Continued 17 On February 13, 2024, California Water Association, a party to the 2021 GRC, completed a filing with the CPUC expressing concerns that the APD departs from standard CPUC practice and precedent on capital projects and early retirements of capital investments. At the CPUC meeting on February 15, 2024 , during the open comment period, a pproximately twenty Cal Water customers, concerned citizens and businesses requested the CPUC to approve the PD and reject the APD. No speakers supported the APD. On February 16, 2024, several California utilities sent a letter to the CPUC expressing concern that the APD departs from standard CPUC practice and precedent.

INVESTOR RELATIONS California 2021 General Rate Case Update, Continued 18 We are unable to determine which of the proposed decisions will be adopted by the CPUC, or if a second alternate proposed decision will be issued by the CPUC. O nce approved by the CPUC, the Cal Water 2021 GRC cumulative adjustment plus interest, which is retroactive to January 1, 2023 , will be recorded.

INVESTOR RELATIONS California 2021 General Rate Case Update Focus on Decoupling Cal Water’s 2021 GRC contains provisions designed to mitigate the absence of a decoupling program: • Lower estimated sales, factoring in continued conservation efforts. • Rates designed to reduce revenue volatility but still send price signal to highest users. • Estimated production costs accounting for realistic mix of water sources. Cal Water and others have appealed CPUC decoupling decision to California Supreme Court; case expected to be heard within the first six months of 2024. In 2022, a Cal Water led coalition secured passage of legislation requiring CPUC to consider decoupling proposals, reversing a portion of CPUC's 2020 decision that prohibited utilities from even applying for decoupling. Cal Water will request decoup ling to be reinstated on January 1, 2026 in its July 1, 2024 GRC. 19

INVESTOR RELATIONS Cal Water’s Cost of Capital Proceeding Update CPUC granted Cal Water’s request to postpone the May 1, 2024 Water Cost of Capital proceeding to May 1, 2025. As a result of the 2023 adjustment from the Water Cost of Capital Mechanism (WCCM), Cal Water’s authorized return on equity (ROE) is 10.27% in 2024. In 2025, the ROE of 10.27% may be adjusted plus or minus any changes from the WCCM during the period from October 1, 2023 to September 30, 2024. WCCM adjusts Cal Water’s return on equity rate up or down when the Moody’s Utilities Bond Index fluctuates more than 100 basis points between Cost of Capital proceedings during the 12 - month period from October 1 to September 30. When the CPUC adopts Cal Water’s May 1, 2025 Cost of Capital proceeding decision, the new authorized capital structure, ROE and cost of debt rates, are expected to be effective on January 1, 2026. 20

INVESTOR RELATIONS PFAS Regulation Update • In March 2023, USEPA published draft Maximum Contaminant Levels (MCLs) for PFAS compounds. • Based on current information, if regulation is adopted in the current proposed form, we estimate capital investments of approximately $215M needed to comply. These capital investments will be incremental to the capital investments included in our GRC filings. o Draft regulation, if unchanged and finalized by 2024, would require compliance by 2027. While our regulators have a strong track record of allowing recovery for regulatorily required water treatment investments, there are also other potential sources of funds that could offset some or all investment over time. Cal Water filed an application to include infrastructure investments as well as operating expenses in existing memorandum account. 21

INVESTOR RELATIONS In Summary 23 2023 Full Year and Fourth Quarter earnings results were in line with expectations given the delayed proposed decision on Cal Water’s 2021 GRC, which had an adverse impact on earnings results. The issuance of a PD and APD on January 24, 2024 is expected to result in a final decision during the first half of 2024. We remain laser focused on executing our strategy and serving our customers.
