CALIFORNIA WATER SERVICE GROUP ANNOUNCES

FIRST QUARTER 2023 RESULTS

SAN JOSE, CA – California Water Service Group (NYSE: CWT) (“Group”) today announced a net loss attributable to Group of $22.2 million and diluted loss per share of $0.40 for the quarter ended March 31, 2023, as compared to net income attributable to Group of $1.1 million and diluted earnings per share of $0.02 for the quarter ended March 31, 2022.

First quarter results primarily reflect the impact of the delayed proposed decision from the California Public Utilities Commission ("CPUC") on California Water Service Company’s (“Cal Water”) pending general rate case (“GRC”) to set new rates, implement new rate design, and establish new standard regulatory mechanisms. The decision was due to be effective on January 1, 2023. Water revenues billed in the first quarter of 2023 were based on 2022 adopted rates and rate design without any benefit from the Water Revenue Adjustment Mechanism (“WRAM”) and Modified Cost Balancing Account (“MCBA”) regulatory mechanisms, which ended on December 31, 2022. First quarter 2023 operating revenue does not include any benefit of new revenue mechanisms (Monterey-Style Water Revenue Adjustment Mechanism and Drought Response Memorandum Account) or rate relief (tracked in the Interim Rates Memorandum Account) due to the delay in the approval of our 2021 GRC Filing. We currently estimate the adverse impact of the delayed decision on first quarter 2023 operating revenue to be between approximately $24.0 million and $34.0 million, which is based on the current positions of the parties to the 2021 GRC Filing and consumption driven regulatory mechanisms.

In September 2022, Cal Water and the Public Advocates Office at the CPUC filed a joint settlement motion with the CPUC covering rate design, sales forecast, and other issues. Litigated items not included in the settlement were capital investment budgets, WRAM balancing account recovery, and recovery of certain expenses. Cal Water intends to implement an authorized 4% interim rate increase beginning in May 2023. The final general rate case decision, once approved, will be retroactive to January 1, 2023, and a cumulative adjustment will be recorded in the quarter in which final approval is received.

Operating revenue was $131.1 million for the quarter ended March 31, 2023, compared to $173.0 million for the same period in 2022. The $41.9 million, or 24.2%, revenue decrease was primarily attributable to an $18.8 million increase in revenue deferral, a $12.1 million decrease in WRAM and MCBA revenue, and a $12.9 million decrease in customer usage. The increase in revenue deferral, which was accompanied by a $15.4 million increase in cost deferral, was primarily due to the large net WRAM and MCBA balance and the recovery periods requested in the April 2023 WRAM/MCBA advice letter filing which extended beyond 24 months from the end of the first quarter of 2023.

Operating expenses for the first quarter of 2023 were $148.6 million, compared to $163.9 million in 2022, a decrease of $15.3 million or 9.3%. Water production costs decreased $6.5 million, or 10.6%, to $55.0 million in 2023 compared to $61.5 million in 2022. The decrease in water production costs was primarily attributable to an 8.8% decrease in customer usage. Other operations expenses for the first quarter of 2023 were $16.6 million, compared to $25.9 million in 2022, a decrease of 35.8%. The decrease was primarily attributed to the deferral of $15.4 million in costs related to the revenue deferral. In addition, administrative and general expenses increased $2.6 million, or 7.7%, to $36.0 million during the quarter, primarily due to increased labor costs.

Other income and expenses were $7.2 million in the first quarter of 2023, an increase of $4.5 million, or 167%, over the first quarter of 2022. The increase was primarily due to unrealized gains on certain non-qualified benefit plan investments of $1.7 million in the first quarter of 2023 compared to $2.9 million in unrealized losses on certain non-qualified benefit plan investments in the first quarter of 2022.

Net interest expense in the first quarter of 2023 increased $1.1 million or 9.7% to $12.0 million as compared to the first quarter of 2022, primarily due to an increase in short-term borrowing rates and higher outstanding line of credit balances.

The effective consolidated income tax rate was approximately 14.6% and 12.0% for the quarters ended March 31, 2023, and 2022, respectively. The change in effective tax rates was primarily due to a reduction in the amortization of the Tax Cuts and Jobs Act excess deferred income tax benefits in 2023 as compared to 2022.

According to President and Chief Executive Officer Martin A. Kropelnicki, first quarter operating results were in line with the Group’s expectations.

“Given the continuing delay on our 2021 General Rate Case for California, our results are not surprising to us and in line with our expectations given the regulatory lag. Eventually, the regulatory process will conclude, but while we wait, we continue to focus on our strategic priorities. In Q1, we completed our purchase of Bethel Greenacres Association in Washington and signed an agreement to purchase Lake Section Water in New Mexico; we introduced PromisePay to provide our customers with an even more convenient way to set up flexible payment plans with us; and we invested $82.0 million in water system improvements that should help us deliver a reliable, high-quality water supply to our communities,” he said.

Liquidity and Financing

On March 31, 2023, the Group and Cal Water entered into syndicated credit agreements, which provide for unsecured revolving credit facilities of up to an initial aggregate amount of $600.0 million for a term of five years. Group and subsidiaries that it designates may borrow up to $200.0 million under Group’s revolving credit facility. Cal Water may borrow up to $400.0 million under its revolving credit facility. Additionally, the credit facilities may be increased by up to an incremental $150.0 million under the Cal Water facility and $50.0 million under the Group facility, subject in each case to certain conditions.

Group maintained $52.3 million of cash as of March 31, 2023 and has additional short-term borrowing capacity of more than $470 million, subject to meeting the borrowing conditions on Group and Cal Water’s line of credit facilities.

The company invested $82.0 million in infrastructure improvements during the first quarter of 2023 compared to $68.5 million during the first quarter of 2022. For 2023, Cal Water’s capital program will be dependent in part on the timing and nature of regulatory approvals in connection with our California GRC filing. Cal Water proposed to the CPUC spending $1.0 billion on new projects in 2022-2024. Capital expenditures in California are evaluated in the context of the pending GRC filing and may change as the case moves forward.

INVESTOR RELATIONS 2022 vs 2023 BILLED AND UNBILLED REVENUES Due to the extremely wet winter in California, Q1 Cal Water sales fell 12% from Q1 2022 Weather also pushed unbilled revenue accrual down $ 5.8M Also, in 2022, sales and production cost changes had been offset $12.1M by the WRAM/MCBA In 2023, we anticipate that the effects of sales changes would be offset by the drought response memorandum account (“DREMA”) and the Monterey - Style Revenue Adjustment Mechanism (“MWRAM”); however due to the delayed CPUC decision, we are unable to record these amounts. • Estimated potential DREMA balance for q1* $6.5 - 7M • Estimated potential MWRAM balance for q1* $9.5 - 11M REVENUE DEFERRAL In accordance with GAAP, we defer revenue and cost related to regulatory balancing accounts not projected to be recovered within 24 months. Accordingly, we deferred an additional $18.8M of revenue, offset by an additional $15.4M of deferred costs, in Q1. *DREMA is an authorized account but the value will be based on final GRC rates. MWRAM was requested in the 2021 GRC and was not disputed by any other party to the proceeding. If approved, its value would also depend on final GRC rates. Ranges are cu rre nt estimates based on available information and may change as the GRC progresses. Due to the mechanisms’ connection to customer billings, first quarter estimates are not necessarily indicative of potential impacts in future quarters. First Quarter Revenue Discussion 6

INVESTOR RELATIONS Unrecorded Regulatory Mechanisms 2022 vs 2023 SALES Due to the delayed GRC we did not record certain regulatory mechanisms in the quarter: Interim Rate Memorandum Account (IRMA): Tracks the difference between interim rates and final rates authorized by the CPUC in our 2021 GRC Filing. For the quarter, the IRMA balance would have recorded between $8M and $15M if a final decision on revenue requirements falls within the range set by the positions of the parties. Our practice is to record IRMA balances as revenue when amounts are known and authorized for recovery after a GRC decision. Incremental Cost Balancing Account (ICBA): Tracks the difference between adopted and recorded water production costs. Due to the delay in the GRC, we are not able to record these amounts. MWRAM: Tracks the difference between sales revenue and modeled single - quantity rate revenue. We cannot record these amounts due to the pending GRC. A range was provided above. DREMA: Tracks reduced sales revenues when customer demand is affected by requests for voluntary or mandatory usage reductions. We cannot record these amounts due to the pending GRC. A range was provided above. 9

INVESTOR RELATIONS 10 California Regulatory Update • In March, the CPUC extended the statutory deadline for the cost of capital case to August 2023. The Commission may issue a proposed decision any time before that date, or it may extend the deadline in a subsequent action. • Given the success of the company’s financing program, our proposed cost of debt in the application was lower than last adopted. The company has not reserved for any potential outcome of the proceeding. In the event the CPUC adopts capital components retroactively to January 1, 2022, we estimate the reduced cost of debt, if adopted at our proposed equity capital structure, would reduce 2022 authorized annual revenue by approximately $11.0 million. This amount could be offset or increased depending on the final cost of equity and capital structure adopted by the CPUC. The potential impact to 2023 authorized annual revenue is dependent on the resolution of the 2021 GRC Filing . • There has been no update on the California General Rate Case during the quarter. 10

INVESTOR RELATIONS 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. 17
