Notes to Unaudited Condensed Consolidated Financial Statements

Dollar amounts in thousands, unless otherwise stated

Note 1. Organization and Operations and Basis of Presentation

California Water Service Group (Company) is a holding company that provides water utility and other related services in California, Washington, New Mexico, Hawaii, and Texas through its wholly-owned and non-wholly owned subsidiaries. California Water Service Company (Cal Water), Washington Water Service Company (Washington Water), New Mexico Water Service Company (New Mexico Water), and Hawaii Water Service Company, Inc. (Hawaii Water) provide regulated utility services under the rules and regulations of their respective state’s regulatory commissions (jointly referred to as the Commissions). CWS Utility Services and HWS Utility Services LLC provide non-regulated water utility and utility-related services. TWSC, Inc. (Texas Water) holds regulated and contracted wastewater utilities. Regulated wastewater utilities held by Texas Water’s investment in joint venture with BVRT Utility Holding Company (BVRT) provide services under the rules and regulation of the Texas Public Utilities Commission.

The Company operates in one reportable segment, providing water and water-related utility services.

Basis of Presentation

The unaudited condensed consolidated interim financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) for interim financial information and in accordance with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X promulgated by the Securities and Exchange Commission (SEC) and therefore do not contain all of the information and footnotes required by GAAP and the SEC for annual financial statements. Interim financial information includes the Company’s accounts and those of its wholly and non-wholly owned subsidiaries. The non-wholly owned subsidiary was consolidated using the voting interest model as the Company owns a majority of the non-wholly owned subsidiary’s voting interests. The interim unaudited condensed consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements included in its Annual Report on Form 10-K for the year ended December 31, 2023 as filed with the SEC on February 29, 2024.

The preparation of the Company’s unaudited condensed consolidated interim financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the balance sheet dates and the reported amounts of revenues and expenses for the periods presented. These include, but are not limited to, estimates and assumptions used in determining the Company’s regulatory asset and liability balances based upon probability assessments of regulatory recovery, utility plant useful lives, revenues earned but not yet billed, asset retirement obligations, allowance for credit losses, pension and other employee benefit plan liabilities, and income tax-related assets and liabilities. Actual results could materially differ from these estimates.

In the opinion of management, the accompanying unaudited condensed consolidated interim financial statements reflect all adjustments, consisting of normal recurring transactions that are necessary to provide a fair presentation of the results for the periods covered.

Due to the seasonal nature of the water business, the results for interim periods are not indicative of the results for a 12-month period. Revenue and income are generally higher in the warm, dry summer months when water usage and sales are greater. Revenue and income are generally lower in the winter months when cooler temperatures and rainfall curtail water usage and sales.

Noncontrolling Interests

Noncontrolling interests in the Company’s unaudited condensed consolidated financial statements represents the 6.2% interest not owned by Texas Water in a consolidated subsidiary. Texas Water obtained control over the subsidiary on May 1, 2021. Since the Company controls this subsidiary, its financial statements are consolidated with those of the Company, and the noncontrolling owner’s 6.2% share of the subsidiary’s net assets and results of operations is deducted and reported as noncontrolling interests on the unaudited Condensed Consolidated Balance Sheet and as net loss attributable to noncontrolling interests in the unaudited Condensed Consolidated Statement of Operations. The Company reports noncontrolling interests in consolidated entities as a component of equity separate from the Company’s equity. The Company’s net income (loss) attributable to California Water Service Group excludes the net loss attributable to the noncontrolling interests.

Operating Revenue

The following table disaggregates the Company’s operating revenue by source for the three and six months ended June 30, 2024 and 2023:


	Three Months Ended June 30,				Six Months Ended June 30,
	2024		2023		2024		2023
Revenue from contracts with customers	$	226,665	$	194,206	$	381,566	$	339,431

Total operating revenue	$	244,299	$	194,044	$	515,048	$	325,144

Revenue from contracts with customers

The Company principally generates operating revenue from contracts with customers by providing regulated water and wastewater services at tariff-rates authorized by the Commissions in the states in which they operate and non-regulated water and wastewater services at rates authorized by contracts with government agencies. Revenue from contracts with customers reflects amounts billed for the volume of consumption at authorized per unit rates, for a service charge, and for other authorized charges.

The Company satisfies its performance obligation to provide water and wastewater services over time as services are rendered. The Company applies the invoice practical expedient and recognizes revenue from contracts with customers in the amount for which the Company has a right to invoice. The Company has a right to invoice for the volume of consumption, for the service charge, and for other authorized charges.

The measurement of sales to customers is generally based on the reading of their meters, which occurs on a systematic basis throughout the month. At the end of each month, the Company estimates consumption since the date of the last meter reading and the corresponding accrued unbilled revenue is recognized. The estimate is based upon the number of unbilled days that month and the average daily customer billing rate from the previous month (which fluctuates based upon customer usage).

Contract terms are generally short-term and at will by customers and, as a result, no separate financing component is recognized for the Company’s collections from customers, which generally require payment within 30 days of billing. The Company applies judgment, based principally on historical payment experience, in estimating its customers’ ability to pay.

Certain customers are not billed for volumetric consumption, but are instead billed a flat rate at the beginning of each monthly service period. The amount is advance billed and is initially deferred. Subsequently, it is recognized over the monthly service period, as the performance obligation is satisfied. The deferred revenue balance or contract liability, which is included in “accrued expenses and other liabilities” on the unaudited Condensed Consolidated Balance Sheets, is inconsequential.

Table of Contents

In the following table, revenue from contracts with customers is disaggregated by class of customers for the three and six months ended June 30, 2024 and 2023:


	Three Months Ended June 30,				Six Months Ended June 30,
	2024		2023		2024		2023

Total revenue from contracts with customers	$	226,665	$	194,206	$	381,566	$	339,431

(a) Other includes accrued unbilled revenue

Regulatory balancing account revenue

Regulatory balancing account revenue is revenue related to revenue mechanisms authorized in California by the California Public Utilities Commission (CPUC). For certain revenue mechanisms, the Company recognizes revenue when it is objectively determinable, probable of recovery and expected to be collected within 24 months following the end of the accounting period. To the extent that revenue is estimated to be collectible beyond 24 months, recognition is deferred. These mechanisms include the Monterey-Style Water Revenue Adjustment Mechanism (MWRAM) which was approved in Cal Water’s 2021 General Rate Case (GRC) filing (2021 GRC) in March of 2024. The MWRAM tracks the difference between the revenue received for actual metered sales through the tiered volumetric rate and the revenue that would have been received with the same actual metered sales if a uniform rate had been in effect. The MWRAM is effective retroactive to January 1, 2023. During the three and six months ended June 30, 2024, the Company recorded $8.2 million and $39.3 million, respectively, of MWRAM revenue.

These mechanisms also include the Water Revenue Adjustment Mechanism (WRAM) which decoupled revenue from the volume of sales and allowed the Company to recognize the adopted level of volumetric revenues. The variance between adopted volumetric revenues and actual billed volumetric revenues for metered accounts was recorded as regulatory balancing account revenue. The WRAM concluded on December 31, 2022; however, the Company has a net WRAM receivable balance for which the Company continues to defer revenue recognition for amounts estimated to be collected beyond 24 months following the end of the accounting period. The Company applied a portion of the proceeds from the California Extended Water and Wastewater Arrearages Payment Program (Extended Program) to eligible customer WRAM balances as discussed below under Allowance for Credit Losses.

Regulatory balancing accounts also include revenue that is recognized for balancing and memorandum accounts when it is probable that future recovery of previously incurred costs or future refunds that are to be credited to customers will occur through the ratemaking process. As a result of the delay in the approval of the 2021 GRC, the CPUC authorized Cal Water to track the effect of the delay on customer billings in an Interim Rates Memorandum Account (IRMA) effective January 1, 2023. Variances between actual customer billings and those that would have been billed assuming the 2021 GRC had been implemented on January 1, 2023 were recorded as regulatory balancing account revenue. The 2021 GRC was approved in March of 2024 and final authorized rates were implemented effective May 31, 2024; as a result, Cal Water calculated and recorded this difference for all of 2023 and the first five months of 2024. Cal Water determined that the IRMA met regulatory asset recognition criteria under accounting standards for regulated utilities. During the three and six months ended June 30, 2024, the Company recorded $7.9 million and $88.6 million, respectively, of revenue for the IRMA.

Non-Regulated Revenue

The following table disaggregates the Company’s non-regulated revenue by source for the three and six months ended June 30, 2024 and 2023:


	Three Months Ended June 30,				Six Months Ended June 30,
	2024		2023		2024		2023
Operating and maintenance revenue	$	3,188	$	3,075	$	6,436	$	6,310
Other non-regulated revenue	1,720		800		2,949		1,582
Non-regulated revenue from contracts with customers	4,908		3,875		9,385		7,892
Lease revenue	605		610		1,226		1,216
Total non-regulated revenue	$	5,513	$	4,485	$	10,611	$	9,108

Operating and maintenance services are provided for non-regulated water and wastewater systems owned by private companies and municipalities. The Company negotiates formal agreements with the customers under which the Company provides operating, maintenance and customer billing services related to the customers’ water system. The formal agreements outline the fee schedule for the services provided. The agreements typically call for a fee-per-service or a flat-rate amount per month. The Company satisfies its performance obligation of providing operating and maintenance services over time as services are rendered; as a result, the Company employs the invoice practical expedient and recognizes revenue in the amount that it has the right to invoice. Contract terms are generally short-term and, as a result, no separate financing component is recognized for its collections from customers, which generally require payment within 30 days of billing.

Other non-regulated revenue primarily relates to services for the design and installation of water mains and other water infrastructure for customers outside the regulated service areas and insurance program administration.

Lease revenue is not considered revenue from contracts with customers and is recognized following operating lease standards. The Company is the lessor in operating lease agreements with telecommunications companies under which cellular phone antennas are placed on the Company’s property.

Allowance for Credit Losses

The Company measures expected credit losses for Customer Receivables, Other Receivables, and Accrued Unbilled Revenue on an aggregated level. These receivables are generally trade receivables due in one year or less or expected to be billed and collected in one year or less. The expected credit losses for Other Receivables and Accrued Unbilled Revenue are inconsequential. Customer receivables include receivables for water and wastewater services provided to residential customers, business, industrial, public authorities, and other customers. The expected credit losses for business, industrial, public authorities, and other customers are inconsequential. The overall risks related to the Company’s receivables are low as water and wastewater services are seen as essential services. The estimate for the allowance for credit losses is based on a historical loss ratio, in conjunction with a qualitative assessment of elements that impact the collectability of receivables to determine if the allowance for credit losses should be further adjusted in accordance with the accounting guidance for credit losses. Management contemplates available current information such as changes in economic factors, regulatory matters, industry trends, payment options and programs available to customers, and the methods that the Company is able to use to ensure payment.

The Company reviews its allowance for credit losses utilizing a quantitative assessment, which includes a trend analysis of customer billings and collections, agings by customer class, and unemployment rates. The Company also utilizes a qualitative assessment, which considers the future collectability of customer outstanding balances, management’s estimate of the cash recovery, and a general assessment of the economic conditions in the locations the Company serves. Based on these assessments, the Company adjusts its allowance for credit losses. The Company has also taken into account $82.0 million of funds that the Company received in April of 2024 from the Extended Program for eligible customers in California of which $57.5 million was applied to eligible past due customer balances during the second quarter of 2024. The remaining balance is expected to be returned to the State Water Resources Control Board (Water Board) in the fourth quarter of 2024 and is included in “accrued expenses and other liabilities” on the unaudited Condensed Consolidated Balance Sheet. The Extended Program was created by the California Legislature, and is administered by the Water Board

and provides relief to community water and wastewater systems for unpaid bills – arrearages – related to the COVID-19 pandemic. Based on the above assessments, the Company determines its allowance for credit losses.

The following table presents the activity in the allowance for credit losses for the six months ended June 30, 2024 and twelve months ended December 31, 2023:


	June 30, 2024		December 31, 2023

Earnings (Loss) per Share

Basic earnings (loss) per share of common stock is computed by dividing the net income (loss) attributable to California Water Service Group by the weighted average number of common shares outstanding during the period. Diluted earnings per share reflect the potential dilution that could occur if securities or other contracts were exercised or converted into common stock. Restricted Stock Awards (RSAs) are included in the common shares outstanding because the shares have all the same voting and dividend rights as issued and unrestricted common stock.

New Accounting Standards and SEC Rules

In November 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures which expands annual and interim disclosure requirements for reportable segments, primarily through enhanced disclosures about significant segment expenses. ASU 2023-07 is effective for the Company’s annual periods beginning January 1, 2024, and for interim periods beginning January 1, 2025, with early adoption permitted. The guidance requires retrospective presentation of all prior periods presented in the financial statements. The Company is currently evaluating the potential effect that the updated standard will have on its financial statement disclosures and does not expect to early adopt.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures to expand the disclosure requirements for income taxes, specifically related to the rate reconciliation and income taxes paid. ASU 2023-09 is effective for the Company's annual periods beginning January 1, 2025, with early adoption permitted. The guidance is applied prospectively with the option of retrospective application for each period presented. The Company is currently evaluating the potential effect that the updated standard will have on its financial statement disclosures and does not expect to early adopt.

In March 2024, the SEC issued SEC Release No. 33-11275, The Enhancement and Standardization of Climate-Related Disclosures for Investors. The final rules enhance disclosures related to the risks and impacts of climate-related matters. In April 2024, the SEC voluntarily stayed the new rules as a result of pending legal challenges. The new rules, if they become effective as adopted, would require various disclosures related to climate-related risks if those risks could have a material impact on the Company’s business, results of operations, or financial condition. Required disclosures would also include information about the Company’s greenhouse gas emissions, if material. In addition, the rules would require disclosure of certain climate-related financial metrics in the Company’s financial statements. The final rules, if they become effective as adopted, would be effective no earlier than the Company’s Annual Report on Form 10-K for the year ending December 31, 2025. The Company is currently evaluating the potential effect that the rules will have on its financial statement disclosures.

Note 3. Stock-Based Compensation

The Company’s 2024 Equity Incentive Plan (2024 Plan) was adopted by the Board of Directors and approved by stockholders on May 29, 2024. The Company reserved 1,600,000 shares of common stock for 2024 Plan awards.

In June of 2024, the Company granted Restricted Stock Awards (RSAs) to Officers and members of the Board of Directors (Directors). Generally, an RSA share represents the right to receive a share of the Company’s common stock and is valued based on the fair market value of the Company’s common stock at the date of grant. The 2024 RSAs granted to Officers vest over 33 months with the first 9 months cliff vesting. RSA granted to the Directors in 2024 vest at the end of 9 months. The 2024 RSAs are recognized as expense evenly over 33 months for the shares granted to Officers and 9 months for the shares granted to the Directors. As of June 30, 2024, there was approximately $3.8 million of total unrecognized compensation cost related to RSAs. The cost is expected to be recognized over a weighted average period of 1.7 years.

A summary of the status of the outstanding RSAs as of June 30, 2024 is presented below:


	Number of RSA Shares	Weighted-Average Grant-Date Fair Value
RSAs at January 1, 2024	53,303	$	55.48
Granted	58,556	49.62
Vested	(32,869)	55.32

RSAs at June 30, 2024	78,990	$	51.20

In June of 2024, the Company granted performance-based Restricted Stock Units (RSUs) to Officers. Generally, an RSU represents the right to receive a share of the Company’s common stock. Each award reflects a target number of shares of common stock that may be issued to the award recipient. The 2024 awards may be earned upon the completion of a 33 month performance period. Whether RSUs are earned at the end of the performance period will be determined based on the achievement of certain performance objectives set by the Organization and Compensation Committee of the Board of Directors in connection with the issuance of the RSUs. The performance objectives are based on the Company’s business plan covering the performance period. The performance objectives include achieving the budgeted return on equity, growth in stockholders’ equity, and application submission targets of grant funding. Depending on the results achieved during the 33 month performance period, the actual number of shares that a grant recipient receives at the end of the performance period may range from 0% to 200% of the target shares granted, provided that the grantee is continuously employed by the Company through the vesting date. If prior to the vesting date employment is terminated by reason of death, disability or normal retirement, then a pro rata portion of this award will vest. The RSUs are recognized as expense ratably over the 33 month performance period using a fair market value of the Company’s common stock at the date of grant and an estimated number of RSUs earned during the performance period. As of June 30, 2024, there was approximately $4.9 million of total unrecognized compensation cost related to RSUs. The cost is expected to be recognized over a weighted average period of 2.0 years.

A summary of the status of outstanding RSUs as of June 30, 2024 is presented below:


	Number of RSU Shares	Weighted-Average Grant-Date Fair Value
RSUs at January 1, 2024	93,078	$	55.41
Granted	66,821	49.62
Performance criteria adjustment	13,735	53.96
Vested	(36,394)	53.96

RSUs at June 30, 2024	137,240	$	52.83

The Company has recorded compensation costs for the RSAs and RSUs which are included in administrative and general operating expenses in the amount of $0.4 million and $1.4 million for the three months ended June 30, 2024 and 2023, respectively. For the six months ended June 30, 2024 and 2023, the Company has recorded compensation costs for the RSAs and RSUs in the amount of $1.1 million and $1.5 million, respectively.

Note 4. Equity

On April 29, 2022, the Company 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 depending on market conditions through an at-the-market equity program over the next three years. The Company intends to use the net proceeds from these sales, after deducting commissions and offering expenses, for general corporate purposes, which may include working capital, construction and acquisition expenditures, investments and repurchases, and redemptions of securities. The Company sold 1,000,000 shares of common stock through its at-the-market equity program and raised proceeds of $52.0 million, net of $0.5 million in commissions paid under the equity distribution agreement, during the three and six months ended June 30, 2024.

During the three months ended June 30, 2023, the Company sold 1,699,849 shares of common stock through its at-the market equity program and raised proceeds of $94.5 million, net of $1.0 million in sales commissions. During the six months ended June 30, 2023, the Company sold 2,025,891 shares of common stock through its at-the-market equity program and raised proceeds of $112.7 million, net of $1.1 million in sales commissions.

In Cal Water’s 2021 GRC decision that was issued in March of 2024, SERP expenses were not approved to be recovered from customers for the years 2023, 2024 and 2025. Without regulatory recovery, Cal Water no longer meets the regulatory asset recognition criteria to record the unrecognized prior service costs and actuarial gain and loss amounts related to the SERP as a regulatory asset. The Company has applied compensation recognition guidance and recorded the unrecognized prior service costs and actuarial gains and losses to accumulated other comprehensive loss. In the first quarter of 2024, the Company reclassified $13.7 million to accumulated other comprehensive loss, which is Cal Water’s cumulative portion of the regulatory asset.

Note 5. Pension Plan and Other Postretirement Benefits

The Company provides a qualified, defined-benefit, non-contributory pension plan for substantially all its employees. The Company makes annual contributions to fund amounts accrued for the qualified pension plan. The Company also maintains an unfunded, non-qualified SERP. The costs of the plans are charged to expense or are capitalized in utility plant as appropriate.

The Company offers medical, dental, vision, and life insurance benefits for retirees and their spouses and dependents. Participants are required to pay a premium, which offsets a portion of the cost.

Cash contributions made by the Company to the pension plans were $0.2 million and $2.9 million for the six months ended June 30, 2024 and 2023, respectively. No cash contributions were made by the Company to the other postretirement benefit plans for the six months ended June 30, 2024. The Company made cash contributions of $0.2 million to the other postretirement benefit plans for the six months ended June 30, 2023. The Company estimates in 2024 that the annual contribution to the pension plans will be $0.7 million and the annual contribution to the other postretirement plans will be $0.2 million.

The following table lists components of net periodic benefit costs for the pension plans and other postretirement benefits. The data listed under “pension plan” includes the qualified pension plan and the non-qualified SERP. The data listed under “other benefits” is for all other postretirement benefits.

Note 6. Short-term and Long-term Borrowings

On March 31, 2023, the Company 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. The Company and subsidiaries that it designates may borrow up to $200.0 million under the Company’s revolving credit facility (the Company facility). Cal Water may borrow up to $400.0 million under its revolving credit facility (the Cal Water 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 Company facility, subject in each case to certain conditions. At the Company’s or Cal Water’s option, as applicable, borrowings under the Company and Cal Water facilities, as applicable, will bear interest annually at a rate equal to (i) the base rate, plus an applicable margin of 0.00% to 0.250%, depending on the Company and its subsidiaries’ consolidated total capitalization ratio, or (ii) Term SOFR, plus an applicable margin of 0.800% to 1.250%, depending on the Company and its subsidiaries’ consolidated total capitalization ratio.

The Company and Cal Water facilities contain affirmative and negative covenants and events of default customary for credit facilities of this type including, among other things, limitations and prohibitions relating to additional indebtedness, liens, mergers, and asset sales. Also, the Company and Cal Water facilities contain financial covenants governing the Company and its subsidiaries’ consolidated total capitalization ratio and interest coverage ratio. As of June 30, 2024, the Company and Cal Water are in compliance with all of the covenant requirements and are eligible to use the full amount of the undrawn portion of the Company and Cal Water facilities, as applicable.

Outstanding borrowings on the Company lines of credit as of June 30, 2024 and December 31, 2023 were $25.0 million and $50.0 million, respectively. Outstanding borrowings on the Cal Water lines of credit as of June 30, 2024 and December 31, 2023 were $220.0 million and $130.0 million, respectively. The average borrowing rate for borrowings on the Company and Cal Water lines of credit during the six months ended June 30, 2024 was 6.38% compared to 5.78% for the same period last year.

Note 7. Income Taxes

The Company adjusts its effective tax rate each quarter to be consistent with the estimated annual effective tax rate. The Company also records the tax effect of unusual or infrequently occurring discrete items.

The provision for income taxes is shown in the tables below:


	Three Months Ended June 30,				Six Months Ended June 30,
	2024		2023		2024		2023
Income tax expense (benefit)	$	9,995	$	1,774	$	26,854	$	(2,076)

Income tax expense increased $8.2 million to $10.0 million for the three months ended June 30, 2024 as compared to $1.8 million for the three months ended June 30, 2023, primarily due to an increase in pre-tax operating income which resulted from the 2021 GRC decision.

Income tax expense increased $29.0 million to $26.9 million for the six months ended June 30, 2024 as compared to $2.1 million tax benefit for the six months ended June 30, 2023, primarily due to an increase in pre-tax operating income, which resulted from the 2021 GRC decision.

The Company’s effective tax rate was 19.6% and 14.9% before discrete items as of June 30, 2024 and June 30, 2023. The increase in the effective tax rate was primarily due to the recognition of income related to the 2021 GRC decision.

On June 27, 2024, California Senate Bill 167 (SB 167) was enacted into law. SB 167 provides for a three-year suspension of net operating losses under the California Corporation tax. Among other things, this new law temporarily disallows the use of net operating loss for years beginning in 2024 through 2026. As a result of the passage of SB 167, the Company accrued approximately $9.4 million of California income taxes for the six months ended June 30, 2024.

The Company had unrecognized tax benefits of approximately $17.0 million and $14.4 million as of June 30, 2024 and 2023, respectively. Included in the balance of unrecognized tax benefits as of June 30, 2024 and 2023, is $5.1 million and $4.6 million, respectively, of tax benefits that, if recognized, would result in an adjustment to the Company’s effective tax rate. The Company does not expect its unrecognized tax benefits to change significantly within the next 12 months.

The IRMA regulatory asset increase was for the additional amount the Company would have billed customers in 2023 and the first five months of 2024 had the 2021 GRC been approved on time. The IRMA regulatory liability represents additional CAP and RSF credits the Company would have provided to customers in 2023 and the first five months of 2024 had the 2021 GRC been approved on time.

The MWRAM regulatory asset represents the difference between the revenue received for actual metered sales through the tiered volumetric rate and the revenue that would have been received with the same actual metered sales if a uniform rate had been in effect.

The ICBA tracks differences between the authorized prices of water production costs and actual prices of water production costs. During the six months ended June 30, 2024, the Company recorded a regulatory liability for certain service territories of $12.7 million as the authorized water production costs were higher than actual water production costs. The Company also recorded a regulatory asset for certain service territories of $3.5 million as the authorized water production costs were lower than actual water production costs. The ICBA regulatory asset is part of “Other regulatory assets” in the table above.

Short-term regulatory assets and liabilities are excluded from the above table. The short-term regulatory assets were $5.5 million as of June 30, 2024 and $64.2 million as of December 31, 2023. The short-term regulatory assets as of June 30, 2024 and December 31, 2023, primarily consisted of net WRAM and MCBA, and PCBA receivables and are included in current assets as part of regulatory balancing accounts on the unaudited Condensed Consolidated Balance Sheets.

Table of Contents

The short-term portion of regulatory liabilities were $12.8 million as of June 30, 2024 and $21.5 million as of December 31, 2023. The short-term regulatory liabilities as of June 30, 2024 and December 31, 2023, primarily consisted of Tax Cuts and Jobs Act regulatory liabilities and HCBA liabilities and are included in current liabilities as part of regulatory balancing accounts on the unaudited Condensed Consolidated Balance Sheets.

Note 9. Commitments and Contingencies

Commitments

The Company has long-term commitments to purchase water from water wholesalers. The Company also has operating and finance leases for water systems, offices, land easements, licenses, equipment, and other facilities. These commitments and leases are described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023.

On August 16, 2022, BVRT, a majority owned subsidiary of Texas Water, through BVRT’s wholly owned subsidiary, Camino Real Utility (Camino Real), entered into a long-term water supply agreement with the Guadalupe Blanco River Authority (GBRA). The Company has provided a limited guarantee to GBRA for agreed upon obligations. GBRA is a water conservation and reclamation district established by the Texas Legislature that oversees water resources for 10 counties. Under the terms of the agreement with GBRA, Camino Real is contracted to receive up to 2,419 acre-feet of potable water annually. The GBRA agreement involves four off-takers, including Camino Real. GBRA plans to extend a potable water pipeline from the City of Lockhart to the City of Mustang Ridge and surrounding areas. Camino Real is contracted to be the utility service provider in this area of the Austin metropolitan region and to provide potable water, recycled water, and wastewater services to portions of the City of Mustang Ridge and surrounding areas. In 2022, Camino Real committed $21.5 million for its share of the cost of the pipeline project. In 2023, Camino Real committed an additional $22.3 million for its share of the cost of the pipeline project. As of June 30, 2024, this committed cash has not been transferred to GBRA and is classified as part of restricted cash on the unaudited Condensed Consolidated Balance Sheets. The Company currently expects the committed cash to be transferred to GBRA before the end of 2024.

Contingencies

Groundwater Contamination

The Company has undertaken litigation against third parties to recover past and future costs related to groundwater contamination in our service areas. The cost of litigation is generally expensed as incurred and any settlement is first offset against such costs. The CPUC’s general policy requires all proceeds from contamination litigation to be used first to pay transactional expenses, then to make customers whole for water treatment costs to comply with the CPUC’s water quality standards. The CPUC allows for a risk-based consideration of contamination proceeds which exceed the costs of the remediation described above and may result in some sharing of proceeds with the shareholder, determined on a case-by-case basis. The CPUC has authorized various memorandum accounts that allow the Company to track significant litigation costs and to request recovery of these costs in future filings and uses of proceeds to comply with CPUC’s general policy.

Other Legal Matters

From time to time, the Company is involved in various disputes and litigation matters that arise in the ordinary course of business. The status of each significant matter is reviewed and assessed for potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and the amount of the range of loss can be estimated, a liability is accrued for the estimated loss in accordance with the accounting standards for contingencies. Legal proceedings are subject to uncertainties, and the outcomes are difficult to predict. Because of such uncertainties, accruals are based on the best information available at the time. While the outcome of these disputes and litigation matters cannot be predicted with any certainty, management does not believe when taking into account existing reserves the ultimate resolution of these matters will materially affect the Company’s financial position, results of operations, or cash flows. As of June 30, 2024 and December 31, 2023, the Company recognized a liability of $4.1 million and $6.0 million, respectively, primarily due to potable water main leaks and other work related legal matters.

The cost of litigation is expensed as incurred and any settlement is first offset against such costs. Any settlement in excess of the cost to litigate is accounted for on a case-by-case basis, dependent on the nature of the settlement.

Note 10. Fair Value of Financial Assets and Liabilities

The accounting guidance for fair value measurements and disclosures provides a single definition of fair value and requires certain disclosures about assets and liabilities measured at fair value. A hierarchical framework for disclosing the observability of the inputs utilized in measuring assets and liabilities at fair value is established by this guidance. The three levels in the hierarchy are as follows:

Level 1—Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets that the Company has the ability to access.

Level 2—Inputs to the valuation methodology include:

•Quoted market prices for similar assets or liabilities in active markets;

•Quoted prices for identical or similar assets or liabilities in inactive markets;

•Inputs other than quoted prices that are observable for the asset or liability; and

•Inputs that are derived principally from or corroborated by observable market data by correlation or other means.

If the asset or liability has a specified (contractual) term, the level 2 input must be observable for substantially the full term of the asset or liability.

Level 3—Inputs to the valuation methodology are unobservable and significant to the fair value measurement.

Specific valuation methods include the following:

Cash, accounts receivable, short-term borrowings, and accounts payable carrying amounts approximated the fair value because of the short-term maturity of the instruments.

Pension and other postretirement benefit plan assets are measured at either net asset value or level 1 depending on the investment.

Long-term debt fair values were estimated using the published quoted market price, if available, or the discounted cash flow analysis, based on the current rates available using a risk-free rate (a U.S. Treasury securities yield curve) plus a risk premium of 0.60%.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

We maintain our accounting records in accordance with GAAP and as directed by the Commissions to which our operations are subject. The process of preparing financial statements in accordance with GAAP requires the use of estimates on the part of management. The estimates used by management are based on historic experience and an understanding of current facts and circumstances. Management believes that the following accounting policies are critical because they involve a higher degree of complexity and judgment, and can have a material impact on our results of operations, financial condition, and cash flows of the business. These policies and their key characteristics are discussed in detail in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 (2023 Annual Report on Form 10-K). They include:

•revenue recognition;

•regulated utility accounting;

Table of Contents

•income taxes; and

•pensions, which include the supplemental executive retirement plan (SERP) and the postretirement health care benefit plan.

For the six months ended June 30, 2024, besides the change noted below there were no other changes in the methodology for computing critical accounting estimates, no additional accounting estimates met the standards for critical accounting policies, and there were no material changes to the important assumptions underlying the critical accounting estimates.

Pension

As a result of Cal Water’s 2021 GRC decision that was issued in March of 2024, SERP expenses were disallowed to be recovered from customers. At this time, we believe it is not probable that future SERP costs will be recovered in future rates for the three-year period in which the 2021 GRC is in effect. As a result, as of March 31, 2024, we have reclassified our SERP regulatory asset for Cal Water to accumulated other comprehensive loss in accordance with generally accepted accounting principles.

CALIFORNIA EXTENDED WATER AND WASTEWATER ARREARAGES PAYMENT PROGRAM (Extended Program)

The California Water and Wastewater Arrearages Payment Program was created by the California Legislature to be administered by the Water Board in order to provide relief to community water and wastewater systems for unpaid bills (arrearages) related to the COVID-19 pandemic.

In 2023, the Extended Program was established and extended the relief period to include arrearages accrued from June 16, 2021 to December 31, 2022. In response to the Extended Program, Cal Water submitted an application for $82.0 million in eligible customer arrearages and $1.0 million in program administrative costs which was approved by the Water Board. Cal Water received the funds in April of 2024 and applied $57.5 million of the funds to eligible past due customer balances during the second quarter of 2024. The remaining balance is expected to be returned to the Water Board in the fourth quarter of 2024.

RESULTS OF OPERATIONS

Overview

Net Income Attributable to California Water Service Group

Net income attributable to California Water Service Group for the three months ended June 30, 2024 was $40.6 million or $0.70 earnings per diluted common share, compared to net income of $9.6 million or $0.17 earnings per diluted common share for the three months ended June 30, 2023. The $31.0 million increase in net income was primarily due to an increase in operating revenue of $50.3 million primarily due to rate increases and an increase in accrued unbilled revenue. Accrued unbilled revenue increased due to an increase in rates and an increase in unbilled days. The revenue increase was partially offset by an increase in total operating expenses of $18.0 million. The total operating expense increase was primarily due to an increase in water production costs of $6.8 million, depreciation and amortization expenses of $3.1 million, and income tax expense of $8.4 million.

Net income attributable to California Water Service Group for the six months ended June 30, 2024 was $110.5 million or $1.90 earnings per diluted common share, compared to net loss of $12.7 million or $0.23 loss per diluted common share for the six months ended June 30, 2023. The $123.1 million increase in net income was primarily due to an increase in operating revenue of $189.9 million primarily as a result of the cumulative adjustment for the impacts of the 2021 GRC, retroactive to January 1, 2023. The revenue increase was partially offset by an increase in total operating expenses of $62.3 million. The total operating expense increase was primarily due to an increase in water production costs of $16.0 million, increases in other operations expenses of $10.1 million, an increase in income tax expense of $29.5 million, and an increase in depreciation and amortization expenses of $6.1 million.

Operating Revenue

For the three months ended June 30, 2024, operating revenue increased $50.3 million, or 25.9%, to $244.3 million as compared to the three months ended June 30, 2023.

For the six months ended June 30, 2024, operating revenue increased $189.9 million, or 58.4%, to $515.0 million as compared to the six months ended June 30, 2023.

Table of Contents

The sources of the change in operating revenue were:


	Three Months Ended June 30,		Six Months Ended June 30,
	2024 vs. 2023		2024 vs. 2023
Net change due to rate changes, usage, and other (1)	$	32,094	$	46,080
Interim Rates Memorandum Account (IRMA) revenue (2)	7,932		88,596
Monterey-Style Water Revenue Adjustment Mechanism (MWRAM) revenue (3)	8,205		39,271
Deferred revenue (4)	2,024		15,957
Net operating revenue increase	$	50,255	$	189,904

1.The net change due to rate changes, usage, and other for the three months ended June 30, 2024 was primarily due to rate increases of $19.3 million and an increase in accrued unbilled revenue of $10.4 million due to increases in rates and unbilled days. For the six months ended June 30, 2024, the net change due to rate changes, usage, and other was primarily driven by rate increases of $31.6 million, an increase in accrued unbilled revenue of $5.8 million due to increases in rates and unbilled days, and a 2% increase in customer usage.

2.Due to the delay in the resolution of the 2021 GRC, the CPUC authorized Cal Water to track in an IRMA the variances between actual customer billings and those that would have been billed assuming the 2021 GRC had been effective January 1, 2023. Such variances are recorded as regulatory balancing account revenue. The 2021 GRC was approved in March of 2024 and final rates for the 2021 GRC were implemented on May 31, 2024. As a result, Cal Water recorded IRMA revenue of $7.9 million for the three months ended June 30, 2024. For the six months ended June 30, 2024, Cal Water recorded IRMA revenue of $88.6 million of which $67.6 million is attributable to 2023, including $17.3 million and $28.4 million that was attributable to the three and six months ended June 30, 2023.

3.MWRAM revenue is the variance between actual metered sales billed through the tiered volumetric rate and the revenue that would have been received with the same actual metered sales if a uniform rate had been in effect. In March of 2024, Cal Water received approval of the 2021 GRC which authorized the use of the MWRAM effective January 1, 2023. As a result, Cal Water recorded MWRAM revenue of $8.2 million for the three months ended June 30, 2024. For the six months ended June 30, 2024, Cal Water recorded MWRAM revenue of $39.3 million of which $17.4 million is attributable to 2023, including $7.4 million and $18.0 million that was attributable to the three and six months ended June 30, 2023.

4.Deferred revenue consists of amounts that are expected to be collected from customers beyond 24 months following the end of the accounting period in which the sales transaction has already occurred. Deferred revenue for the three months ended June 30, 2024 decreased due to a decrease in the amount expected to be collected beyond 24 months. Deferred revenue for the six months ended June 30, 2024 decreased as we applied $46.0 million from the Extended Program against certain eligible WRAM receivables during the first six months of 2024.

Total Operating Expenses

For the three months ended June 30, 2024, total operating expenses increased $18.0 million, or 10.1%, to $196.1 million, as compared to $178.1 million for the three months ended June 30, 2023. The increase was primarily due to increases in water production costs, depreciation and amortization, and income tax expense.

For the six months ended June 30, 2024, total operating expenses increased $62.3 million, or 19.1%, to $389.0 million, as compared to $326.7 million for the six months ended June 30, 2023. The increase was primarily due to increases in water production costs, other operations, depreciation and amortization, and income tax expense.

Sources of Supply

Sources of water as a percent of total water production are listed in the following table:


	Three Months Ended June 30,				Six Months Ended June 30,
	2024		2023		2024		2023

Water Production Costs

Water production costs increased $6.8 million, or 9.6%, for the three months ended June 30, 2024 as compared to the same period last year primarily due to an increase in wholesale rates and higher customer usage.

Water production costs increased $16.0 million, or 12.7%, for the six months ended June 30, 2024 as compared to the same period last year primarily due recording a cumulative adjustment of $9.2 million for the impacts of the 2021 GRC and increases in wholesale rates and customer usage. For the six months ended June 30, 2024, we recorded $6.5 million of water production costs for the Incremental Cost Balancing Accounts (ICBA) attributable to fiscal year 2023, including $1.7 million and $2.9 million, respectively, attributable to water production costs during the three and six months ended June 30, 2023.

The components of water production costs are shown in the table below:


	Three Months Ended June 30,						Six Months Ended June 30,
	2024		2023		Change		2024		2023		Change
Purchased water	$	59,939	$	55,930	$	4,009	$	100,167	$	98,668	$	1,499
Purchased power	12,814		10,831		1,983		22,846		19,221		3,625

ICBA	(409)		—		(409)		8,470		—		8,470
Total	$	77,644	$	70,867	$	6,777	$	141,829	$	125,875	$	15,954

Other Operations

Other operations expenses increased $10.1 million, or 23.9%, for the six months ended June 30, 2024 as compared to the same period in 2023. The increase was primarily due to the recognition of $13.6 million of costs associated with recognized deferred WRAM revenue, which was partially offset by a $4.2 million decrease in bad debt expense as a result of applying arrearage funds to eligible, previously written-off accounts.

Depreciation and Amortization

Depreciation and amortization expense increased $3.2 million and $6.1 million for the three and six months ended June 30, 2024, respectively, as compared to the same periods in 2023. The increases were primarily due to utility plant placed in service in 2023.

Income Tax Expense

Income tax expense increased $8.4 million and $29.5 million for the three and six months ended June 30, 2024, respectively as compared to the same periods in 2023. The increases in income tax expense were primarily due to an increase in pre-tax operating income for the three and six months ended June 30, 2024 compared to the same period in 2023 attributable to the recognition of income related to the 2021 GRC decision in 2024.

REGULATORY MATTERS

California Regulatory Activity

2024 GRC Application

On July 8, 2024, Cal Water submitted Infrastructure Improvement Plans for its California districts from 2025-2027 in its 2024 GRC application with the CPUC. The application also proposes a Low-Use Water Equity Program, that would, if approved as filed, decouple revenue from water sales, to assist low-water-using, lower-income customers.

The required, triennial filing begins an approximately 18-month review process by the CPUC, which will analyze the Infrastructure Improvement Plans, operating budget proposals, and a Low-Use Water Equity Program to establish water rates for 2026-2028 that reflect the actual cost of providing safe, reliable water service. Associated rates set by the CPUC would become effective no sooner than January 2026.

In the plans, 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. About 46% of the proposed new infrastructure improvements are to replace aging water pipelines, which such improvements are designed to enhance water supply reliability to support customers’ and firefighters’ everyday and emergency needs. The plans also include, among other projects:

•Water quality upgrades to treat for existing and newly regulated contaminants.

•Infrastructure replacements to help ensure reliable delivery of water service.

•Equipment such as generators to help withstand power outages and shutoffs, and solar installation projects to help reduce Cal Water’s dependency on the electric power grid and lessen its environmental footprint.

•Physical and cyber security and safety enhancements to help protect facilities, customers, and employees.

•Water supply initiatives to help safeguard long-term reliability and sustainability of water sources.

•Advanced Metering Infrastructure to aid conservation efforts and enhance water-use efficiency.

Cal Water’s proposed Low-Use Water Equity Program would, if approved as filed, decouple revenue from water sales across its regulated service areas. The program is designed to work in conjunction with Cal Water’s proposed four-tier rate design and sales forecast proposals to enhance affordability—particularly for low-use and low-income customers—plus reinforce conservation goals, while providing the utility an opportunity to recover its authorized revenue requirement in a timely manner.

To support these investments, 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.

2021 GRC

The CPUC approved a decision on March 7, 2024 on the 2021 GRC. The decision marked the end of an extensive review of Cal Water’s water system improvement plans, costs, and rates. The decision as issued adopts a revised version of the alternate proposed decision issued January 24, 2024, and increases adopted revenues, after corrections, for 2023 by approximately $41.5 million retroactive to January 1, 2023. It also potentially increases revenues by up to approximately $30.0 million for 2024 and $30.6 million for 2025, subject to the CPUC’s earnings test and inflationary adjustments.

The decision authorizes Cal Water to invest approximately $1.2 billion from 2021 through 2024 in water system infrastructure projects that we believe are needed to continue providing safe, reliable water service to customers throughout California. This also includes approximately $160 million of infrastructure projects that may be submitted for recovery via the CPUC’s advice letter process.

The CPUC’s decision approves a progressive rate design that is intended to provide budget stability while benefiting low-income and low-water-using customers by significantly decreasing the cost of the first six units of water consumed and increasing the percentage of fixed costs that are recovered in the service charge.

On March 15, 2024, Cal Water submitted a request for expedited corrections in the March 7th decision. The decision and its appendices contain certain language, numbers, and calculations that are inconsistent or do not fully reflect the

Table of Contents

substantive outcomes described in the approved decision. On April 23, 2024, the executive director of the CPUC issued a decision approving the corrections.

On April 1, 2024, Cal Water submitted an advice letter requesting an increase in annual revenue of $42.5 million for all of its rate making areas (besides Grand Oaks) effective May 1, 2024. The advice letter was approved and included the effects of the expense offsets of $4.7 million and cost of capital filing of $11.4 million that were implemented on January 1, 2024, as well as $5.8 million in rate base offsets that were effective on May 1, 2024. The remaining $20.6 million increase was primarily due to 2024 escalations. Cal Water implemented the new rates incorporating all these items on May 31, 2024.

2021 GRC IRMA

The 2021 GRC was approved in March of 2024 and final rates for the 2021 GRC were implemented on May 31, 2024; as a result, Cal Water calculated and recorded a regulatory asset of $88.6 million and a corresponding increase to revenue for the difference between final rates and interim rates for all of 2023 and the first five months of 2024. Cal Water also recorded a regulatory liability of $8.0 million and a corresponding increase to regulatory assets for Customer Assistance Program (CAP) and Rate Support Fund (RSF) program credits that would have been given to customers had the rate case been approved on time. Cal Water expects to file an advice letter to recover/refund these balances in the third quarter of 2024 with the recovery/refund rates expected to be implemented in the fourth quarter of 2024.

Rate Base Offset Requests

For construction projects authorized in the 2021 GRC as advice letter projects, Cal Water is allowed to request rate base offsets to increase revenues after the project goes into service. In March of 2024, Cal Water submitted a $39.1 million rate base offset advice letter to recover $5.8 million of annual revenue increases in all of its regulated districts. The new rates were implemented on May 31, 2024, as discussed above.

Per- and Polyfluoroalkyl Substances Memorandum Account (PFAS MA)

On April 18, 2024, the CPUC dismissed without prejudice Cal Water’s application requesting authorization to modify a previously approved PFAS-expense memorandum account to include capital investments related to PFAS compliance for future recovery. The dismissal does not preclude Cal Water from seeking regulatory recovery for its capital investments. Cal Water may seek recovery through a separate application or a GRC application. Cal Water expects to refile its application by the end of 2024.

California Supreme Court Decision on WRAM

The CPUC issued a decision effective August 27, 2020 requiring that Class A water utilities submitting GRC filings after the effective date be precluded from proposing the use of a full decoupling WRAM in their next GRCs. In September 2020, Cal Water filed an Application for Rehearing at the CPUC seeking to reverse the August 27, 2020 CPUC decision. In September 2021, the CPUC denied the Application for Rehearing. On or about October 27, 2021, Cal Water along with four other Class A California water utilities filed Petitions for a Writ of Review with the California Supreme Court (Court). On May 18, 2022, the Court issued writs granting review and ordered the CPUC and other filing parties to submit additional pleadings to the Court. The final pleadings were submitted on January 13, 2023. Oral arguments were made on May 8, 2024 and, on July 8, 2024, the Court issued a unanimous decision voiding the WRAM provisions in the August 27, 2020 CPUC decision. As a result, Cal Water and other Class A water utilities submitting GRC filings are no longer precluded from proposing the use of a full decoupling WRAM in their GRCs, as reflected in the 2024 GRC filing.

LIQUIDITY

Cash Flow from Operating Activities

During the six months ended June 30, 2024, we generated cash flow from operations of $120.9 million compared to $37.5 million for the same period in 2023. The increase in the first six months of 2024 as compared to the same period in 2023 is primarily due to the receipt of $83.0 million from the Extended Program, as discussed above. Cash generated by operations varies during the year due to customer billings, and timing of collections and contributions to our benefit plans.

The increase in net income for the six months ended June 30, 2024 as compared to the same period from prior year was primarily due to the recording of $127.9 million of operating revenue for the MWRAM and IRMA during the first six months of 2024 due to the resolution of the 2021 GRC. There was an associated increase to regulatory assets related to MWRAM and IRMA operating revenue. The Company intends to begin billing for the recovery of these regulatory assets in the fourth quarter of 2024.

During the six months ended June 30, 2024, we made cash contributions of $0.2 million to our employee pension plan and did not make any cash contribution to our other postretirement benefit plans. During the six months ended June 30, 2023,

Table of Contents

we made cash contributions of $2.9 million and $0.2 million, respectively, to our pension plans and to our other postretirement benefit plans. The 2024 estimated cash contribution to the pension plans and other postretirement benefits plans are expected to be approximately $0.7 million and $0.2 million, respectively.

The water business is seasonal. Billed revenue is lower in the cool, wet winter months when less water is used compared to the warm, dry summer months when water use is highest. This seasonality results in the possible need for short-term borrowings under the bank lines of credit in the event cash is not sufficient to cover operating costs during the winter period. The increase in cash flow during the summer allows for a pay down of short-term borrowings. Customer water usage can be lower than normal in years when more than normal precipitation falls in our service areas or temperatures are lower than normal, especially in the summer months. The reduction in water usage reduces cash flow from operations and increases the need for short-term bank borrowings.

Cash Flow from Investing Activities

During the six months ended June 30, 2024 and 2023, we used $214.4 million and $177.2 million, respectively, of cash for Company-funded and developer-funded utility capital expenditures. Cash used in investing activities fluctuates each year largely due to the availability of construction resources and our ability to obtain construction permits in a timely manner. For 2024, our utility capital expenditures are estimated to be $365.0 million, which excludes an estimated $20.0 million of developer-funded capital expenditures.

Cash Flow from Financing Activities

Net cash provided by financing activities for the six months ended June 30, 2024 was $91.1 million compared to $144.4 million for the same period in 2023. For 2024, this includes our issuance of $52.0 million of Company common stock through our at-the-market equity program and $1.4 million through our employee stock purchase plan. For 2023, this includes our issuance of $112.7 million of Company common stock through our at-the-market equity program and $1.2 million through our employee stock purchase plan.

During the six months ended June 30, 2024 and 2023, we borrowed $295.0 million and $150.0 million, respectively, on our unsecured revolving credit facilities. We made repayments on our unsecured revolving credit facilities of $230.0 million and $90.0 million during the six months ended June 30, 2024 and 2023, respectively. During the six months ended June 30, 2023, we also paid $1.6 million in issuance costs for the Company and Cal Water facilities entered into on March 31, 2023.

On March 31, 2023, the Company and Cal Water entered into the Company and Cal Water credit facilities, which provide for unsecured revolving credit facilities of up to an initial aggregate amount of $600.0 million for a term of five years. The Company and subsidiaries that it designates may borrow up to $200.0 million under the Company’s revolving credit facility (the Company facility). Cal Water may borrow up to $400.0 million under the Cal Water revolving credit facility (the Cal Water 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 Company facility, subject in each case to certain conditions.

The net IRMA, MWRAM, WRAM and Modified Cost Balancing Account receivable balances were $134.2 million and $91.6 million as of June 30, 2024 and 2023, respectively. The receivable balances were primarily financed by Cal Water using short-term and long-term financing arrangements to meet operational cash requirements. Interest on the receivable balances, which represents the interest recoverable from customers, is limited to the then-current 90-day commercial paper rates, which typically are significantly lower than Cal Water’s short and long-term financing rates.

Short-term and Long-term Financing

During the six months ended June 30, 2024, we utilized cash generated from operations and temporary borrowings on our previous unsecured revolving credit facilities to fund operations and capital investments.

In future periods, management anticipates funding our utility plant needs through a balance of long term debt and equity.

Short-term liquidity is provided by the Company and Cal Water facilities and internally generated funds. Long-term financing is accomplished through the use of both debt and equity. The Company and subsidiaries that it designates may borrow up to $200.0 million under the Company facility. Cal Water may borrow up to $400.0 million under the Cal Water facility; however, all borrowings must be repaid within 24 months as authorized by the CPUC. The proceeds from the Company and Cal Water facilities may be used for working capital purposes.

As of June 30, 2024 and December 31, 2023, short-term borrowings of $245.0 million and $180.0 million, respectively, were outstanding on the Company and Cal Water facilities.

Table of Contents

Given our ability to access our lines of credit on a daily basis, cash balances are managed to levels required for daily cash needs and excess cash is invested in short-term or cash equivalent instruments. Minimal operating levels of unrestricted cash are maintained for Washington Water, New Mexico Water, Hawaii Water and Texas Water.

The Company and Cal Water facilities contain affirmative and negative covenants and events of default customary for credit facilities of this type including, among other things, limitations and prohibitions relating to additional indebtedness, liens, mergers, and asset sales. Also, the Company and Cal Water facilities contain financial covenants that require the Company and its subsidiaries’ consolidated total capitalization ratio not to exceed 66.7% and an interest coverage ratio of three or more. As of June 30, 2024, we are in compliance with all of the covenant requirements and are eligible to use the full amount of the undrawn portion of the Company and Cal Water facilities.

Long-term financing, which includes First Mortgage Bonds, other debt securities, and common stock, has typically been used to replace short-term borrowings and fund utility plant expenditures. Internally generated funds, after making dividend payments, provide positive cash flow, but have not been at a level to meet the needs of our utility plant expenditure requirements. Management expects this trend to continue given our planned utility plant expenditures for the next five years. Some utility plant expenditures are funded by payments received from developers for contributions in aid of construction or advances for construction. Funds received for contributions in aid of construction are non-refundable, whereas funds classified as advances for construction are generally refundable over 40 years. Management believes long-term financing is available to meet our cash flow needs through issuances of both debt and equity instruments.

Summarized Financial Information for Guarantors and the Issuer of Guaranteed Securities

On April 17, 2009, Cal Water (Issuer) issued $100.0 million aggregate principal amount of 5.500% First Mortgage Bonds due 2040, all of which are fully and unconditionally guaranteed by the Company (Guarantor). Certain subsidiaries of the Company do not guarantee the security and are referred to as Non-guarantors. The Guarantor fully, absolutely, irrevocably and unconditionally guarantees the punctual payment when due, whether at stated maturity, by acceleration, by notice of prepayment or otherwise, of the principal, premium, if any, and interest on the bonds. The bonds rank equally among Cal Water’s other First Mortgage Bonds.

The following tables present summarized financial information of the Issuer subsidiary and the Guarantor. The information presented below excludes eliminations necessary to arrive at the information on a consolidated basis. In presenting the summarized financial statements, the equity method of accounting has been applied to the Guarantor interests in the Issuer. The summarized information excludes financial information of the Non-guarantors, including earnings from and investments in these entities.

Dividends

During the six months ended June 30, 2024, our quarterly common stock dividend payments were $0.56 per share compared to $0.52 per share for the six months ended June 30, 2023. For the full year 2023, the payout ratio was 113.8% of net income. On a long-term basis, our goal is to achieve a dividend payout ratio of 60% of net income.

At the July 31, 2024 meeting, the Company’s Board of Directors declared the third quarter dividend of $0.28 per share payable on August 23, 2024, to stockholders of record on August 12, 2024. This was our 318th consecutive quarterly dividend.

2024 Financing Plan

We intend to fund our utility plant needs in future periods through a relatively balanced approach between long-term debt and equity. The Company and Cal Water have a syndicated unsecured revolving line of credit of $200.0 million and $400.0 million, respectively, for short-term borrowings. As of June 30, 2024, the Company’s and Cal Water’s availability on these unsecured revolving lines of credit was $175.0 million and $180.0 million, respectively.

Book Value and Stockholders of Record

Book value per common share was $26.26 at June 30, 2024 compared to $24.72 at December 31, 2023. There were approximately 1,738 stockholders of record for our common stock as of May 6, 2024.

Utility Plant Expenditures

During the six months ended June 30, 2024, utility plant expenditures totaled $214.4 million for Company-funded and developer-funded projects. For 2024, we estimate utility capital expenditures to be $365.0 million, which excludes an estimated $20.0 million of developer-funded capital expenditures.

As of June 30, 2024, construction work in progress was $354.0 million. Construction work in progress includes projects that are under construction but not yet complete and placed in service.

WATER SUPPLY

Our source of supply varies among our operating districts. Certain districts obtain all of their supply from wells; some districts purchase all of their supply from wholesale suppliers; and other districts obtain supply from a combination of wells and wholesale suppliers. A small portion of supply comes from surface sources and is processed through Company-owned water treatment plants. To the best of management’s knowledge, we are meeting water quality, environmental, and other regulatory standards for all Company-owned systems.

Historically, approximately half of our annual water supply is pumped from wells. State groundwater management agencies operate differently in each state. Some of our wells extract ground water from water basins under state ordinances. These are adjudicated groundwater basins, in which a court has settled the dispute between landowners, or other parties over how much annual groundwater can be extracted by each party. All of our adjudicated groundwater basins are located in the State of California. Our average annual groundwater extraction from adjudicated groundwater basins approximates

Table of Contents

6.7 billion gallons or 13.1% of our total average annual (2022-2023) water supply pumped from wells. Historically, we have extracted less than 100% of our annual adjudicated groundwater rights and have the right to carry forward up to 20% of the unused amount to the next annual period. All of our remaining wells extract ground water from managed or unmanaged water basins. There are no set limits for the ground water extracted from these water basins. Our average annual groundwater extraction from managed groundwater basins approximates 29.7 billion gallons or 57.6% of our total average annual water supply pumped from wells. Our average annual groundwater extraction from unmanaged groundwater basins approximates 15.1 billion gallons or 29.3% of our total average annual water supply pumped from wells. Many managed groundwater basins we extract water from have groundwater recharge facilities for which we financially support the recharge activities by paying well pump taxes. For the six months ended June 30, 2024 and 2023, our well pump taxes were $10.3 million and $8.0 million, respectively. In 2014, the State of California enacted the Sustainable Groundwater Management Act of 2014 (SGMA). The law and its implementing regulations required most basins to create a sustainability agency by 2017, develop a sustainability plan by the end of 2022, and show progress toward sustainability by 2027. We expect that after the SGMA provisions are fully implemented, all the Company’s California groundwater will be produced from sustainably managed and/or adjudicated basins.

California’s normal weather pattern yields little precipitation between mid-spring and mid-fall. The Washington Water service areas receive precipitation in all seasons, with the heaviest amounts during the winter. New Mexico Water's rainfall is heaviest in the summer monsoon season. Hawaii Water receives precipitation throughout the year, with the largest amounts in the winter months. Typically, water usage in all service areas is highest during the warm and dry summers and declines in the cool winter months. Rain and snow during the winter months in California replenish underground water aquifers and fill reservoirs, providing the water supply for subsequent delivery to customers. As of July 17, 2024, the State of California snowpack water content for the 2023-2024 water year was 90% of long-term averages (per the California Department of Water Resources, Northern Sierra Precipitation Accumulation report). The northern Sierra region is the most important for the state’s urban water supplies. The central and southern portions of the Sierras have recorded 84% and 80%, respectively, of long-term averages. Management believes that supply pumped from underground aquifers and purchased from wholesale suppliers will be adequate to meet customer demand during 2024 and thereafter. Long-term water supply plans are developed for each of our districts to help assure an adequate water supply under various operating and supply conditions. Some districts have unique challenges in meeting water quality standards, but management believes that supplies will meet current standards using currently available treatment processes or by installing the best available technologies.

On May 31, 2018, California’s Governor signed two bills (Assembly Bill 1668 and Senate Bill 606) into law that were intended to establish long-term standards for water use efficiency. The bills revise and expand the existing urban water management plan requirements to include five-year drought risk assessments, water shortage contingency plans, and annual water supply/demand assessments. The Water Board, in conjunction with the California Department of Water Resources, has adopted long-term water use standards for indoor residential use, outdoor residential use, water losses, and other uses. Cal Water is also required to calculate and report on urban water use targets each year, that compares actual urban water use to the targets. Management believes that Cal Water is well positioned to comply with all such regulations.

In April of 2024, the U.S. Environmental Protection Agency (EPA) finalized a National Primary Drinking Water Regulation establishing legally enforceable levels, known as maximum contaminant levels (MCLs), for six PFAS in drinking water. Under the PFAS regulation, water utilities across the country are required to complete initial PFAS monitoring by 2027 and to implement treatment for sources exceeding the MCL by 2029. We estimate a capital investment of approximately $226.0 million will be required to comply with the regulation.

On April 17, 2024, the Water Board adopted an MCL of 10 parts per billion for Chromium-6 in drinking water. Our water systems in California will be required to comply with the regulation within two to four years. We developed and installed treatment for this contaminant at most of our impacted water sources when the same MCL was originally set in 2014, which was subsequently vacated for administrative reasons. After the MCL was vacated, we continued to treat our impacted water systems. We anticipate installing treatment for the remaining impacted sources before the regulatory deadline.

CONTRACTUAL OBLIGATIONS

During the six months ended June 30, 2024, there were no material changes in contractual obligations outside the normal course of business.

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

We do not hold, trade in or issue derivative financial instruments and therefore are not exposed to risks these instruments present. Our market risk to interest rate exposure is limited because the cost of long-term financing and short-term bank borrowings, including interest costs, is covered in consumer water rates as approved by the Commissions. We do not have foreign operations; therefore, we do not have a foreign currency exchange risk. Our business is sensitive to commodity prices and is most affected by changes in purchased water and purchased power costs.

Historically, the CPUC’s balancing account or offsettable expense procedures allowed for increases in purchased water, pump tax, and purchased power costs to be flowed through to consumers. A significant percentage of our net income and cash flows come from California regulated operations; therefore the CPUC’s actions have a significant impact on our business. See Item 2, “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Regulatory Matters.”

Item 4. CONTROLS AND PROCEDURES

(a) Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) that are designed to ensure that information required to be disclosed in our reports filed or submitted under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported, within the time periods specified in the Securities and Exchange Commission's rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow for timely decisions regarding required disclosure.

In designing and evaluating the disclosure controls and procedures, management, including the Chief Executive Officer and Chief Financial Officer, recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Accordingly, our disclosure controls and procedures have been designed to provide reasonable assurance of achieving their objectives.

Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of June 30, 2024 and concluded that our disclosure controls and procedures were effective at the reasonable assurance level.

(b) Changes to Internal Control over Financial Reporting

There have been no changes in our internal control over financial reporting during the second quarter of 2024 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II—OTHER INFORMATION

Item 1. LEGAL PROCEEDINGS

From time to time, the Company is involved in various disputes and litigation matters that arise in the ordinary course of business. The status of each significant matter is reviewed and assessed for potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and the amount of the range of loss can be reasonably estimated, a liability is accrued for the estimated loss in accordance with the accounting standards for contingencies. Legal proceedings are subject to uncertainties, and the outcomes are difficult to predict. Because of such uncertainties, accruals are based on the best information available at the time. While the outcome of these disputes and litigation matters cannot be predicted with any certainty, management does not believe when taking into account existing reserves the ultimate resolution of these matters will materially affect the Company’s financial position, results of operations, or cash flows. In the future, we may be involved in disputes and litigation related to a wide range of matters, including employment, construction, environmental issues and operations. Litigation can be time-consuming and expensive and could divert management’s time and attention from our business. In addition, if we are subject to new lawsuits or disputes, we might incur significant legal costs and it is uncertain whether we would be able to recover the legal costs from customers or other third parties. Please refer to Note 9, “Commitments and Contingencies” for more information.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Operations and Basis of Presentation	Organization and Operations and Basis of Presentation California Water Service Group (Company) is a holding company that provides water utility and other related services in California, Washington, New Mexico, Hawaii, and Texas through its wholly-owned and non-wholly owned subsidiaries. California Water Service Company (Cal Water), Washington Water Service Company (Washington Water), New Mexico Water Service Company (New Mexico Water), and Hawaii Water Service Company, Inc. (Hawaii Water) provide regulated utility services under the rules and regulations of their respective state’s regulatory commissions (jointly referred to as the Commissions). CWS Utility Services and HWS Utility Services LLC provide non-regulated water utility and utility-related services. TWSC, Inc. (Texas Water) holds regulated and contracted wastewater utilities. Regulated wastewater utilities held by Texas Water’s investment in joint venture with BVRT Utility Holding Company (BVRT) provide services under the rules and regulation of the Texas Public Utilities Commission. The Company operates in one reportable segment, providing water and water-related utility services. Basis of Presentation The unaudited condensed consolidated interim financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) for interim financial information and in accordance with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X promulgated by the Securities and Exchange Commission (SEC) and therefore do not contain all of the information and footnotes required by GAAP and the SEC for annual financial statements. Interim financial information includes the Company’s accounts and those of its wholly and non-wholly owned subsidiaries. The non-wholly owned subsidiary was consolidated using the voting interest model as the Company owns a majority of the non-wholly owned subsidiary’s voting interests. The interim unaudited condensed consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements included in its Annual Report on Form 10-K for the year ended December 31, 2023 as filed with the SEC on February 29, 2024. The preparation of the Company’s unaudited condensed consolidated interim financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the balance sheet dates and the reported amounts of revenues and expenses for the periods presented. These include, but are not limited to, estimates and assumptions used in determining the Company’s regulatory asset and liability balances based upon probability assessments of regulatory recovery, utility plant useful lives, revenues earned but not yet billed, asset retirement obligations, allowance for credit losses, pension and other employee benefit plan liabilities, and income tax-related assets and liabilities. Actual results could materially differ from these estimates. In the opinion of management, the accompanying unaudited condensed consolidated interim financial statements reflect all adjustments, consisting of normal recurring transactions that are necessary to provide a fair presentation of the results for the periods covered. Due to the seasonal nature of the water business, the results for interim periods are not indicative of the results for a 12-month period. Revenue and income are generally higher in the warm, dry summer months when water usage and sales are greater. Revenue and income are generally lower in the winter months when cooler temperatures and rainfall curtail water usage and sales. Noncontrolling Interests Noncontrolling interests in the Company’s unaudited condensed consolidated financial statements represents the 6.2% interest not owned by Texas Water in a consolidated subsidiary. Texas Water obtained control over the subsidiary on May 1, 2021. Since the Company controls this subsidiary, its financial statements are consolidated with those of the Company, and the noncontrolling owner’s 6.2% share of the subsidiary’s net assets and results of operations is deducted and reported as noncontrolling interests on the unaudited Condensed Consolidated Balance Sheet and as net loss attributable to noncontrolling interests in the unaudited Condensed Consolidated Statement of Operations. The Company reports noncontrolling interests in consolidated entities as a component of equity separate from the Company’s equity. The Company’s net income (loss) attributable to California Water Service Group excludes the net loss attributable to the noncontrolling interests.

Commitments and Contingencies	Jun. 30, 2024
Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Commitments The Company has long-term commitments to purchase water from water wholesalers. The Company also has operating and finance leases for water systems, offices, land easements, licenses, equipment, and other facilities. These commitments and leases are described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023. On August 16, 2022, BVRT, a majority owned subsidiary of Texas Water, through BVRT’s wholly owned subsidiary, Camino Real Utility (Camino Real), entered into a long-term water supply agreement with the Guadalupe Blanco River Authority (GBRA). The Company has provided a limited guarantee to GBRA for agreed upon obligations. GBRA is a water conservation and reclamation district established by the Texas Legislature that oversees water resources for 10 counties. Under the terms of the agreement with GBRA, Camino Real is contracted to receive up to 2,419 acre-feet of potable water annually. The GBRA agreement involves four off-takers, including Camino Real. GBRA plans to extend a potable water pipeline from the City of Lockhart to the City of Mustang Ridge and surrounding areas. Camino Real is contracted to be the utility service provider in this area of the Austin metropolitan region and to provide potable water, recycled water, and wastewater services to portions of the City of Mustang Ridge and surrounding areas. In 2022, Camino Real committed $21.5 million for its share of the cost of the pipeline project. In 2023, Camino Real committed an additional $22.3 million for its share of the cost of the pipeline project. As of June 30, 2024, this committed cash has not been transferred to GBRA and is classified as part of restricted cash on the unaudited Condensed Consolidated Balance Sheets. The Company currently expects the committed cash to be transferred to GBRA before the end of 2024. Contingencies Groundwater Contamination The Company has undertaken litigation against third parties to recover past and future costs related to groundwater contamination in our service areas. The cost of litigation is generally expensed as incurred and any settlement is first offset against such costs. The CPUC’s general policy requires all proceeds from contamination litigation to be used first to pay transactional expenses, then to make customers whole for water treatment costs to comply with the CPUC’s water quality standards. The CPUC allows for a risk-based consideration of contamination proceeds which exceed the costs of the remediation described above and may result in some sharing of proceeds with the shareholder, determined on a case-by-case basis. The CPUC has authorized various memorandum accounts that allow the Company to track significant litigation costs and to request recovery of these costs in future filings and uses of proceeds to comply with CPUC’s general policy. Other Legal Matters From time to time, the Company is involved in various disputes and litigation matters that arise in the ordinary course of business. The status of each significant matter is reviewed and assessed for potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and the amount of the range of loss can be estimated, a liability is accrued for the estimated loss in accordance with the accounting standards for contingencies. Legal proceedings are subject to uncertainties, and the outcomes are difficult to predict. Because of such uncertainties, accruals are based on the best information available at the time. While the outcome of these disputes and litigation matters cannot be predicted with any certainty, management does not believe when taking into account existing reserves the ultimate resolution of these matters will materially affect the Company’s financial position, results of operations, or cash flows. As of June 30, 2024 and December 31, 2023, the Company recognized a liability of $4.1 million and $6.0 million, respectively, primarily due to potable water main leaks and other work related legal matters. The cost of litigation is expensed as incurred and any settlement is first offset against such costs. Any settlement in excess of the cost to litigate is accounted for on a case-by-case basis, dependent on the nature of the settlement.

Fair Value of Financial Assets and Liabilities

Fair Value Disclosures [Abstract]

Fair Value of Financial Assets and Liabilities

Level 1—Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets that the Company has the ability to access.

Level 2—Inputs to the valuation methodology include:

•Quoted market prices for similar assets or liabilities in active markets;

•Quoted prices for identical or similar assets or liabilities in inactive markets;

•Inputs other than quoted prices that are observable for the asset or liability; and

•Inputs that are derived principally from or corroborated by observable market data by correlation or other means.

If the asset or liability has a specified (contractual) term, the level 2 input must be observable for substantially the full term of the asset or liability.

Level 3—Inputs to the valuation methodology are unobservable and significant to the fair value measurement.

Specific valuation methods include the following:

Cash, accounts receivable, short-term borrowings, and accounts payable carrying amounts approximated the fair value because of the short-term maturity of the instruments.

Pension and other postretirement benefit plan assets are measured at either net asset value or level 1 depending on the investment.
