CALIFORNIA WATER SERVICE GROUP

Notes to Unaudited Condensed Consolidated Financial Statements

June 30, 2025

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) indirectly holds regulated and contracted wastewater utilities through a majority owned joint venture, BVRT Utility Holding Company (BVRT). BVRT's wastewater utilities provide services under the rules and regulation of the Texas Public Utilities Commission.

***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 refers to BVRT, a 95.9% owned subsidiary of Texas Water that is consolidated using the voting interest model as the Company owns a majority of voting interests in the non-wholly owned subsidiary. 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, 2024 as filed with the SEC on February 27, 2025.

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 consolidated 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 Interest***

Noncontrolling interest in the Company's unaudited condensed consolidated financial statements represents the 4.1% interest not owned by Texas Water in BVRT. Texas Water obtained control over BVRT on May 1, 2021. Since the Company controls BVRT, its financial statements are consolidated with those of the Company, and the noncontrolling owner's 4.1% share of BVRT's net assets and results of operations is deducted and reported as noncontrolling interest in total equity on the unaudited Condensed Consolidated Balance Sheet, as net loss attributable to noncontrolling interest in the unaudited Condensed Consolidated Statements of Operations, and as comprehensive loss attributable to noncontrolling interest in the unaudited Condensed Consolidated Statements of Comprehensive Income. The Company reports noncontrolling interest in consolidated entities as a component of equity separate from the Company's equity. The Company's net income and comprehensive income attributable to California Water Service Group excludes the loss attributable to the noncontrolling interest.

<u>Revenue from contracts with customers</u>

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 and other third parties. 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 a corresponding accrued and 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.

In the following table, revenue from contracts with customers is disaggregated by class of customers for the three and six months ended June 30, 2025 and 2024:

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Other includes changes to accrued and unbilled revenue

<u>Regulatory balancing account revenue</u>

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 CA GRC) in March of 2024. The MWRAM tracks the

------

<u>[**Table of Contents**](#ice5ce5d5e64c4d3e92e80d6098b265e2_7)</u>

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 fluctuates with the seasonality of the water business. During the warm, dry summer months when water use is typically highest, the MWRAM will reflect an overcollection of revenue compared to an undercollection in the cool, wet winter months when less water is typically used.

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 is 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.

Regulatory balancing accounts also include revenue that is recognized 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 CA GRC, the CPUC authorized Cal Water to track the effect of the delay on customer billings in an Interim Rates Memorandum Account (IRMA). Variances between actual customer billings and those that would have been billed assuming the 2021 CA GRC had been implemented on January 1, 2023 were recorded as regulatory balancing account revenue. The 2021 CA GRC was approved in March of 2024 and final authorized rates were implemented effective May 31, 2024; as a result, for the first six months of 2024, Cal Water calculated and recorded the IRMA 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.

***Non-Regulated Revenue***

The following table disaggregates the Company's non-regulated revenue by source for the three and six months ended June 30, 2025 and 2024:

---

| | | | | |
|:---|:---|:---|:---|:---|
| | **Three Months Ended June 30,** | **Three Months Ended June 30,** | **Six Months Ended June 30,** | **Six Months Ended June 30,** |
| | **2025** | **2024** | **2025** | **2024** |
| Contract operating and maintenance revenue | $3239 | $3188 | $6506 | $6436 |
| Other non-regulated revenue | 1091 | 1720 | 2339 | 2949 |
| &nbsp;&nbsp;&nbsp;Non-regulated revenue from contracts with customers | 4330 | 4908 | 8845 | 9385 |
| Lease revenue | 581 | 605 | 1147 | 1226 |
| &nbsp;&nbsp;&nbsp;Total non-regulated revenue | $4911 | $5513 | $9992 | $10611 |

---

Contract 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 a 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 contract 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 and 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 and 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,

------

<u>[**Table of Contents**](#ice5ce5d5e64c4d3e92e80d6098b265e2_7)</u>

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 applicable accounting guidance. 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 encourage 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, accordingly.

The following table presents the activity in the allowance for credit losses for the six months ended June 30, 2025 and twelve months ended December 31, 2024:

---

| | | |
|:---|:---|:---|
| | **June 30, 2025** | **December 31, 2024** |
| Beginning balance | $4128 | $2854 |
| Provision for credit loss expense | 1663 | 5890 |
| Write-offs | (2498) | (5054) |
| Recoveries | 290 | 438 |
| &nbsp;&nbsp;&nbsp;Total ending allowance balance | $3583 | $4128 |

***Cash, Cash Equivalents, and Restricted Cash***

The following table provides a reconciliation of cash, cash equivalents, and restricted cash within the unaudited Condensed Consolidated Balance Sheets that sum to the total of the same such amounts shown on the unaudited Condensed Consolidated Statements of Cash Flows (see Note 9 for further details on restricted cash):

---

| | | |
|:---|:---|:---|
| | **June 30, 2025** | **December 31, 2024** |
| Cash and cash equivalents | $50539 | $50121 |
| Restricted cash | 45617 | 45566 |
| Total cash, cash equivalents, and restricted cash | $96156 | $95687 |

---

***Earnings per Share***

Basic earnings per share of common stock is computed by dividing the net income attributable to California Water Service Group by the weighted average number of common shares outstanding during the period. Diluted earnings per share reflects 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 all have the same voting and dividend rights as issued and unrestricted common stock.

***New Accounting Standards***

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 paid income taxes. 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 evaluating the requirements of the guidance to determine the impact on its financial statement disclosures upon adoption and does not expect to adopt the standard early.

In November 2024, the FASB issued ASU 2024-03, Disaggregation of Income Statement Expenses, which requires disaggregation of certain Consolidated Statement of Operations' expense captions into specified categories in disclosures within the footnotes to the financial statements. ASU 2024-03 is effective for the Company's annual periods beginning January 1, 2027, with early adoption permitted. The guidance is applied prospectively with the option of retrospective application for each period presented. The Company is evaluating the requirements of the guidance to determine the impact on its financial statement disclosures upon adoption and does not expect to adopt the standard early.

**Note 3. Stock-Based Compensation**

The Company's 2024 Equity Incentive Plan (2024 Equity 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 awards the Company is authorized to issue pursuant to the 2024 Equity Plan. In addition, the Board of Directors reauthorized 158,950 shares for issuance under its legacy equity incentive plan.

In March of 2025, the Company granted RSAs to Officers and members of the Board of Directors (Directors). Generally, an RSA 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 2025 RSAs granted to Officers vest over 36 months with the first 12 months cliff vesting and the remaining RSAs vesting quarterly thereafter. RSAs granted to the Directors in 2025 vest at the end of 12 months. The 2025 RSAs are recognized as expense evenly over 36 months for the shares granted to Officers and 12 months for the shares granted to the Directors. As of June 30, 2025, there was approximately $3.5 million of total unrecognized compensation cost related to RSAs. The cost is expected to be recognized over a weighted average period of 1.8 years.

A summary of the status of the outstanding RSAs as of June 30, 2025 is presented below:

---

| | | |
|:---|:---|:---|
| | **Number of RSA Shares** | **Weighted-Average Grant-Date Fair Value** |
| RSAs at January 1, 2025 | 70349 | $50.63 |
| Granted | 60956 | 46.57 |
| Vested | (44717) | 46.56 |
| RSAs at June 30, 2025 | 86588 | $47.88 |

---

In March of 2025, 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 2025 RSU awards may be earned upon the completion of a 36-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 2025 performance objectives are based on the Company's business plan covering the performance period. The two performance objectives for the 2025 to 2027 performance period include 1) achieving targets indicative of stockholder return and 2) achieving targets associated with PFAS investment in water monitoring and treatment as well as water contamination cost recovery. Depending on the results achieved during the 36-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 RSUs 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 36-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, 2025, there was approximately $5.7 million of total unrecognized compensation cost related to outstanding RSUs under the program. The cost is expected to be recognized over a weighted average period of 1.9 years.

A summary of the status of outstanding RSUs as of June 30, 2025 is presented below:

---

| | | |
|:---|:---|:---|
| | **Number of RSU Shares** | **Weighted-Average Grant-Date Fair Value** |
| RSUs at January 1, 2025 | 133666 | $52.75 |
| Granted | 84039 | 46.57 |
| Performance criteria adjustment | 4352 | 45.45 |
| Vested | (31313) | 45.45 |
| Forfeited | (4593) | 52.34 |
| RSUs at June 30, 2025 | 186151 | $49.43 |

---

The Company has recorded compensation costs for the RSAs and RSUs that are included in administrative and general operating expenses in the amount of $1.3 million and $0.4 million for the three months ended June 30, 2025 and 2024, respectively. For the six months ended June 30, 2025 and 2024, the Company has recorded compensation costs for the RSAs and RSUs in the amount of $2.6 million and $1.1 million, respectively.

**Note 4. Equity**

On May 14, 2025, 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 (2025 Equity Agreement) from time to time, depending on market conditions, through an at-the-market equity program over the succeeding three years. The 2025 Equity Agreement replaced the previous agreement that ended in the second quarter of 2025. Pursuant to the terms of the 2025 Equity Agreement, the Company may enter into forward sale agreements with forward counterparties. The Company intends to use the net proceeds from equity 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. During the six months ended June 30, 2025, the Company did not utilize the at-the-market equity program.

During the six months ended June 30, 2024, the Company sold 1,000,000 shares of common stock through its previous 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.

The Company's changes in total equity for the three and six months ended June 30, 2025 and 2024 were as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) This accumulated other comprehensive loss component is included in the computation of net periodic costs for the Company's supplemental executive retirement plan (SERP), specifically the following components: amortization of unrecognized (gain) loss and amortization of prior service credit.

**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 (other postretirement benefit plans). Participants are required to pay a premium, which offsets a portion of the cost.

------

<u>[**Table of Contents**](#ice5ce5d5e64c4d3e92e80d6098b265e2_7)</u>

Cash contributions made by the Company to the pension plans were $3.3 million and $0.2 million for the six months ended June 30, 2025 and 2024, respectively. No cash contributions were made by the Company to the other postretirement benefit plans for the six months ended June 30, 2025 and 2024, respectively. The Company estimates in 2025 that the annual contribution to the pension plans will be $5.2 million and no cash annual contribution will be made to the other postretirement plans.

The following tables list 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 benefit plans.

The service cost portion of the pension plan and other postretirement benefit plans is recognized in administrative and general expenses within the unaudited Condensed Consolidated Statements of Operations. Other components of net periodic benefit costs include interest costs, expected return on plan assets, amortization of prior service costs, and recognized net actuarial losses (gains) and are reported together as other components of net periodic benefit cost in other income and expenses within the unaudited Condensed Consolidated Statements of Operations.

**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 0.25%, depending on the Company and its subsidiaries' consolidated total capitalization ratio, or (ii) Term SOFR, plus an applicable margin of 0.80% to 1.25%, 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, 2025, 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.

------

<u>[**Table of Contents**](#ice5ce5d5e64c4d3e92e80d6098b265e2_7)</u>

Outstanding borrowings on the Company line of credit as of June 30, 2025 and December 31, 2024 were $65.0 million and $40.0 million, respectively. Outstanding borrowings on the Cal Water line of credit as of June 30, 2025 and December 31, 2024 were $295.0 million and $165.0 million, respectively. The average borrowing rate for borrowings on the Company and Cal Water lines of credit during the six months ended June 30, 2025 was 5.33% compared to 6.38% 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 table below:

---

| | | | | |
|:---|:---|:---|:---|:---|
| | **Three Months Ended June 30,** | **Three Months Ended June 30,** | **Six Months Ended June 30,** | **Six Months Ended June 30,** |
| | **2025** | **2024** | **2025** | **2024** |
| Income tax expense | $8667 | $9995 | $11405 | $26854 |

---

Income tax expense decreased $1.3 million and $15.4 million for the three and six months ended June 30, 2025, as compared to the three and six months ended June 30, 2024. The decrease in income tax expense is primarily due to the decrease in pre-tax operating income, which resulted from the 2021 CA GRC decision in the first three months of 2024.

The Company's effective tax rate was 17.1% and 19.6% before discrete items as of June 30, 2025 and June 30, 2024, respectively. The decrease in the effective tax rate was primarily due to the recognition of income related to the 2021 CA GRC decision in the first three months of 2024.

On July 4, 2025, the legislation formally titled "An Act to Provide for Reconciliation Pursuant to Title II of H. Con. Res. 14" (the Act) was signed into law. Aspects of the Act contain technical matters that require management to interpret the legislation and make judgments until further guidance becomes available. The Company is currently evaluating the impact of the Act, changes in interpretations, and guidance on legislative intent to the Company's consolidated financial statements. As the legislation was signed into law after the close of the Company's second quarter, the impacts, if any, are not included in the Company's operating results for the six months ended June 30, 2025.

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 state net operating losses for years beginning in 2024 through 2026.

The Company had unrecognized tax benefits of approximately $19.9 million and $17.0 million as of June 30, 2025 and 2024, respectively. Included in the balance of unrecognized tax benefits as of June 30, 2025 and 2024, is $5.6 million and $5.1 million, respectively, of tax benefits that, if recognized, would result in an increase to the Company's effective tax rate. The Company does not expect its unrecognized tax benefits to change significantly within the next 12 months.

Short-term regulatory assets and liabilities are excluded from the above table. The short-term regulatory assets were $63.2 million as of June 30, 2025 and $55.9 million as of December 31, 2024. The short-term regulatory assets as of June 30, 2025 primarily consisted of IRMA, MWRAM, and ICBA receivables. As of December 31, 2024, the short-term regulatory assets primarily consisted of IRMA and MWRAM receivables. The short-term regulatory assets are included in current assets under regulatory balancing accounts on the unaudited Condensed Consolidated Balance Sheets.

The short-term portion of regulatory liabilities was $17.6 million as of June 30, 2025 and $22.6 million as of December 31, 2024. The short-term regulatory liabilities as of June 30, 2025 consisted of Tax Cuts and Jobs Act (TCJA) regulatory liabilities, ICBA regulatory liabilities, PFAS settlement proceeds (see Note 9, Commitments and Contingencies), and IRMA regulatory liabilities. As of December 31, 2024, the short-term regulatory liabilities primarily consisted of TCJA regulatory liabilities, ICBA regulatory liabilities, and IRMA regulatory liabilities. The short-term regulatory liabilities are included in current liabilities under regulatory balancing accounts on the unaudited Condensed Consolidated Balance Sheets.

------

<u>[**Table of Contents**](#ice5ce5d5e64c4d3e92e80d6098b265e2_7)</u>

The PFAS settlement proceeds in the table above represents amounts the Company does not expect to reclassify to Contributions in Aid of Construction (CIAC) in the next 12 months. The Company is required by the Commissions to provide the benefit of the PFAS settlement proceeds to customers through CIAC once PFAS related remediation projects are placed in service. Since the Company is required to provide the benefit of the settlement proceeds to customers, the Company recorded the PFAS settlement proceeds as a regulatory liability and will reclassify them to CIAC once the related projects are placed in service.

**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, 2024.

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, 2025, 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 2025.

***Contingencies***

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.

<u>Groundwater Contamination</u>

The Company has undertaken litigation against third parties to recover past and future costs related to groundwater contamination in its 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.

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

<u>Other Legal Matters</u>

While the probable outcome of disputes and litigation matters, including those concerning groundwater contamination, 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. 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:

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

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.

The Company's specific valuation methods include the following:

Cash, accounts receivable, short-term borrowings, and accounts payable carrying amounts approximated the fair value due to 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 are estimated using the published quoted market price, if available, or using a 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 0.7%.

**Note 12. Segment Information**

The Company principally provides water and water-related utility services in California, Washington, New Mexico, Hawaii, and Texas. The Company's operating segments were aggregated into one reportable segment as the operating segments provide similar services and operate in similar regulatory environments. The Company defines its segments on the basis of the way in which internally reported financial information is regularly reviewed by the chief operating decision maker (CODM) to analyze financial performance, make decisions, and allocate resources.

The Company's CODM is the Chairman, President and Chief Executive Officer. The CODM assesses performance of the segment and decides how to allocate resources on a consolidated basis based on consolidated net income. The CODM uses consolidated net income to evaluate income generated from the segment in making operating, capital, and business decisions.

The CODM is regularly provided with only the consolidated operating expenses at the same level of detail as noted on the face of the unaudited Condensed Consolidated Statements of Operations. Total assets are also provided as noted on the face of the unaudited Condensed Consolidated Balance Sheets.

**FORWARD-LOOKING STATEMENTS**

This quarterly report, including all documents incorporated by reference, contains forward-looking statements within the meaning established by the Private Securities Litigation Reform Act of 1995 (the PSLRA). The forward-looking statements are intended to qualify under provisions of the federal securities laws for "safe harbor" treatment established by the PSLRA.

**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, 2024 (2024 Annual Report on Form 10-K). They include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• regulated utility accounting;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• income taxes; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• pensions, which include the supplemental executive retirement plan, and the postretirement health care benefit plan.

For the six months ended June 30, 2025, there were no material 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.

<u>Income taxes</u>

On July 4, 2025, the legislation formally titled "An Act to Provide for Reconciliation Pursuant to Title II of H. Con. Res. 14" (the Act) was signed into law. Aspects of the Act contain technical matters that require management to interpret the legislation and make judgments until further guidance becomes available. We are currently evaluating the impact of the Act, changes in interpretations, and guidance on legislative intent to our consolidated financial statements.

**RESULTS OF OPERATIONS**

***Overview***

<u>Net Income Attributable to California Water Service Group</u>

Net income attributable to California Water Service Group for the three months ended June 30, 2025 was $42.2 million or $0.71 earnings per diluted common share, compared to net income of $40.6 million or $0.70 earnings per diluted common share for the three months ended June 30, 2024. The $1.6 million increase in net income was primarily the result of an increase in operating revenue of $20.7 million primarily due to rate increases and an increase in customer usage. This was partially offset by an increase in total operating expenses of $17.0 million. The total operating expenses increase was primarily due to an increase in water production costs of $7.9 million, an increase in other operations expense of $6.1 million, and an increase in depreciation and amortization expenses of $3.1 million.

Net income attributable to California Water Service Group for the six months ended June 30, 2025 was $55.5 million or $0.93 earnings per diluted common share, compared to net income of $110.5 million or $1.90 earnings per diluted common share for the six months ended June 30, 2024. The $55.0 million decrease in net income was primarily due to a decrease in operating revenue of $46.1 million primarily as a result of the cumulative adjustment in the first six months of 2024 for the impacts of the 2021 CA GRC delayed approval, partially offset by rate increases and an increase in customer usage. Additionally, total operating expenses increased $5.8 million. The total operating expense increase was primarily due to increases in other operations expense of $8.0 million, water production costs of $6.7 million, and depreciation and amortization expenses of $6.2 million. The increases were partially offset by a decrease in income tax expense of $16.3 million primarily due to lower pre-tax income.

<u>Operating Revenue</u>

For the three months ended June 30, 2025, operating revenue increased $20.7 million, or 8.5%, to $265.0 million as compared to $244.3 million for the three months ended June 30, 2024.

For the six months ended June 30, 2025, operating revenue decreased $46.1 million, or 9.0%, to $468.9 million as compared to $515.0 million for the six months ended June 30, 2024.

The sources of the change in operating revenue were:

---

| | | |
|:---|:---|:---|
| | **Three Months Ended June 30,** | **Six Months Ended June 30,** |
| | **2025 vs. 2024** | **2025 vs. 2024** |
| Net change due to rate changes, usage, and other (1) | $30312 | $58612 |
| Interim Rates Memorandum Account (IRMA) revenue (2) | (7932) | (88596) |
| Monterey-Style Water Revenue Adjustment Mechanism (MWRAM) revenue (3) | (1535) | (17791) |
| Deferred revenue (4) | (190) | 1654 |
| &nbsp;&nbsp;&nbsp;Net operating revenue change | $20655 | $(46121) |

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.The net change due to rate changes, usage, and other for the three months ended June 30, 2025 was primarily due to rate increases of $23.9 million and an increase in customer usage of $7.0 million. For the six months ended June 30, 2025, the net change was due to rate changes, usage, and other was primarily driven by rate increases of $45.5 million, an increase in customer usage of $8.7 million, the recognition of Palos Verdes Pipeline Memorandum Account related revenue of $3.8 million (see "Palos Verdes Peninsula Water Reliability Project" in Regulatory Matters below for more details), and an increase in accrued and unbilled revenue of $1.3 million due to an increase in rates. This was partially offset by $2.4 million of other 2023 revenue recorded in the first six months of 2024 as a result of the resolution of the 2021 CA GRC that did not recur in the first six months of 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.Due to the delay in the resolution of the 2021 CA 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 CA GRC had been effective January 1, 2023. Such variances were recorded as regulatory balancing account revenue. The 2021 CA GRC was approved in March of 2024 and final rates for the 2021 CA 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;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 CA GRC which authorized the use of the MWRAM effective January 1, 2023. For the three months ended June 30, 2025 and 2024, Cal Water recorded MWRAM revenue of $6.7 million and $8.2 million, respectively. For the six months ended June 30, 2025 and 2024, Cal Water recorded MWRAM revenue of $21.5 million and $39.3 million, respectively. Of the $39.3 million recorded MWRAM revenue for the six months ended June 30, 2024, $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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;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 occurred. Deferred revenue for the six months ended June 30, 2025 decreased and revenue increased by $1.7 million due to a change in the amount expected to be collected beyond 24 months.

<u>Total Operating Expenses</u>

For the three months ended June 30, 2025, total operating expenses increased $17.0 million, or 8.7%, to $213.1 million, as compared to $196.1 million for the three months ended June 30, 2024. The increase was primarily due to increases in water production costs, other operations expense, and depreciation and amortization expense, partially offset by lower income tax expense.

------

<u>[**Table of Contents**](#ice5ce5d5e64c4d3e92e80d6098b265e2_7)</u>

For the six months ended June 30, 2025, total operating expenses increased $5.8 million, or 1.5%, to $394.8 million, as compared to $389.0 million for the six months ended June 30, 2024. The increase was primarily due to increases in water production costs, other operations expense, and depreciation and amortization expense, partially offset by lower income tax expense.

<u>Sources of Supply</u>

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

---

| | | | | |
|:---|:---|:---|:---|:---|
| | **Three Months Ended June 30,** | **Three Months Ended June 30,** | **Six Months Ended June 30,** | **Six Months Ended June 30,** |

| Surface | 4% | 6% | 2% | 4% |
| Total | 100% | 100% | 100% | 100% |

---

<u>Water Production Costs</u>

Water production costs increased $7.9 million, or 10.1%, for the three months ended June 30, 2025 as compared to the same period in the prior year primarily due to an increase in wholesale rates and higher customer usage.

Water production costs increased $6.7 million, or 4.7%, for the six months ended June 30, 2025 as compared to the same period in the prior year primarily due to an increase in wholesale rates and higher customer usage, partially offset by a decrease of $6.5 million related to the recording of Incremental Cost Balancing Accounts (ICBA) expense in the first six months of 2024 attributable to fiscal year 2023 due to the delayed decision in our 2021 CA GRC. The $6.5 million attributable to fiscal year 2023 included $1.7 million and $2.9 million, respectively, attributable to water production costs for 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,** | **Three Months Ended June 30,** | **Three Months Ended June 30,** | **Six Months Ended June 30,** | **Six Months Ended June 30,** | **Six Months Ended June 30,** |
| | **2025** | **2024** | **Change** | **2025** | **2024** | **Change** |
| Purchased water | $67225 | $60397 | $6828 | $116228 | $110707 | $5521 |
| Purchased power | 11895 | 11890 | 5 | 20205 | 20925 | (720) |
| Pump taxes | 6383 | 5357 | 1026 | 12061 | 10197 | 1864 |
| &nbsp;&nbsp;&nbsp;Total | $85503 | $77644 | $7859 | $148494 | $141829 | $6665 |

---

<u>Other Operations</u>

Other operations expenses increased $6.1 million, or 23.7%, for the three months ended June 30, 2025 as compared to the same period in 2024. The increase was primarily due to a $3.9 million increase in bad debt expense, a $1.0 million increase in labor expense, and a $0.5 million increase in software expense. The increase in bad debt expense was primarily due to lower bad debt expense in 2024 as a result of applying arrearage funds to eligible, previously written-off accounts.

Other operations expenses increased $8.0 million, or 15.2%, for the six months ended June 30, 2025 as compared to the same period in 2024. The increase was primarily due to a $4.2 million increase in bad debt expense, a $1.3 million increase in labor expense, a $0.6 million increase in miscellaneous office expenses, and a $0.6 million increase in software expense. These increases were partially offset by a $0.6 million reduction in conservation program expenses. The increase in bad debt expense was primarily due to lower bad debt expense in 2024 as a result of applying arrearage funds to eligible, previously written-off accounts.

<u>Depreciation and Amortization</u>

Depreciation and amortization expense increased $3.1 million and $6.2 million for the three and six months ended June 30, 2025, as compared to the same periods in 2024. These increases were primarily due to utility plant placed in service in 2024.

------

<u>[**Table of Contents**](#ice5ce5d5e64c4d3e92e80d6098b265e2_7)</u>

<u>Income Tax Expense</u>

Income tax expense decreased $1.8 million and $16.3 million for the three and six months ended June 30, 2025, as compared to the same periods in 2024. The decreases in income tax expenses were primarily due to decreases in pre-tax operating income for the three and six months ended June 30, 2025, compared to the same periods in 2024.

**REGULATORY MATTERS**

***California Regulatory Activity***

<u>2024 CA GRC Application</u>

On July 8, 2024, Cal Water submitted Infrastructure Improvement Plans (the Plans) for its California districts for the period of 2025 to 2027 in its 2024 CA 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 Plans, operating budget proposals, and the Low-Use Water Equity Program to establish water rates for 2026 to 2028 that reflect the cost of providing safe, reliable water service. Associated rates set by the CPUC would become effective no sooner than January 2026. Cal Water has concluded an initial pre-hearing conference and an Administrative Law Judge (ALJ) and Commissioner have been assigned to the case. The Commissioner issued the Scoping Memo and Ruling in November 2024 identifying the issues to be addressed and setting the schedule for the proceeding. At the start of 2025, public participation hearings were conducted and Cal Water received California Public Advocate's testimony responding to the 2024 CA GRC application. Cal Water submitted rebuttal testimony in late March 2025. The Assigned Commissioner also issued an Amended Scoping Memo and Ruling on March 13, 2025 granting in part Cal Water's request to modify the ex-parte rules, and denying Cal Water's request to modify the issues within the scope of the proceeding. Settlement discussions took place during April 2025, and hearings before the ALJ occurred in May 2025. After the hearings, the ALJ issued a ruling requesting additional information that parties to the proceeding responded to in June 2025. Briefs were filed on July 7, 2025 and reply briefs were filed on July 28, 2025. A final law and motion hearing is scheduled for August 5, 2025 at which point the case is expected to be submitted to the ALJ to draft a proposed decision.

In the Plans, Cal Water proposes to invest more than $1.6 billion in its districts from 2025 to 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. 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:

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Infrastructure replacements to help provide reliable delivery of water service.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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 the Company's environmental footprint.

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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 the authorized revenue requirement associated with water consumption 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.

<u>Escalation Increase Requests</u>

As a part of the decision on the 2021 CA GRC, Cal Water was authorized to request annual escalation rate increases for 2025 for those districts that passed the CPUC's earnings test. In November of 2024, Cal Water requested 2025 escalation

------

<u>[**Table of Contents**](#ice5ce5d5e64c4d3e92e80d6098b265e2_7)</u>

rate increases for 18 of its regulated districts. The increase in annual adopted gross revenue associated with the November 2024 filing was $27.2 million. The new rates were implemented on January 1, 2025.

<u>Rate Base Offset Requests</u>

For construction projects authorized in the 2021 CA GRC as advice letter projects, Cal Water is allowed to request rate base offsets to increase revenues after the project goes into service. In October of 2024, Cal Water submitted a $5.7 million rate base offset advice letter to recover $0.9 million of annual revenue increases in 9 of its regulated districts. The new rates were implemented on January 1, 2025.

In May of 2025, Cal Water submitted a $11.4 million rate base offset advice letter to recover $1.6 million of annual revenue increases in all of its regulated districts (excluding Grand Oaks). The new rates were implemented on July 1, 2025.

<u>Expense Offset Requests</u>

Expense offsets are dollar-for-dollar increases in revenue to match increased expenses, and therefore do not affect net operating income. In October of 2024, Cal Water submitted an advice letter to request offsets for increases in purchased water costs and pump taxes in 8 of its regulated districts totaling $17.1 million. The new rates were implemented on January 1, 2025.

In June of 2025, Cal Water submitted an advice letter to request expense offsets for increases in purchased water costs and pump taxes in 5 of its regulated districts totaling $5.1 million. The new rates were implemented on July 1, 2025.

In July of 2025, Cal Water submitted an advice letter to request expense offsets for increases in purchased water costs and pump taxes in 2 of its regulated districts totaling $2.6 million. The new surcharges are expected to be implemented on August 1, 2025.

<u>PFAS</u>

In June of 2025, Cal Water filed an application with the CPUC requesting authorization to spend $125.0 million (net of litigation settlement proceeds after deducting fees and expenses) for PFAS treatment in 6 of its regulated districts in 2026 and 2027. The associated requested annual revenue increase for 2027 and 2028 is $6.7 million and $9.0 million, respectively. The impact to the annual revenue requirement is expected to be adjusted downwards for additional litigation proceeds that Cal Water receives. The application also includes a proposal for the amortization of incremental costs tracked in the PFAS memorandum account for these 6 regulated districts totaling $2.5 million.

<u>Palos Verdes Peninsula Water Reliability Project</u>

On January 30, 2025, a final decision was issued that approved Cal Water's request to include $14.2 million of incremental capital costs in rate base and for a temporary surcharge to recover $3.8 million of carrying costs tracked in the Palos Verdes Pipeline Memorandum Account. New base rates were implemented on February 1, 2025 and new surcharges were implemented on April 1, 2025.

<u>California Drought Memorandum Account (DRMA)</u>

On January 30, 2025, a final decision was issued that approved Cal Water's request to recover $1.4 million of incremental costs tracked in the DRMA. New surcharges were implemented on April 1, 2025.

***Regulatory Activity - Other States***

<u>Washington Water Service – Stroh's 2025 Rate Case</u>

On March 22, 2025, the Washington Utilities and Transportation Commission approved a tariff update for the Stroh's water system to increase revenues by $0.2 million. The general rate increase was approved on May 22, 2025, implemented into rates over two years. The first implementation of new rates was effective May 23, 2025, and the second implementation of new rates is effective May 23, 2026.

<u>Hawaii Water Service - Waikoloa 2024 Rate Case</u>

In October of 2024, Hawaii Water filed a rate case with the Hawaii Public Utility Commission to increase revenues across the five Waikoloa water systems by $5.3 million. In May of 2025, the Division of Consumer Advocates filed testimony supporting a $4.3 million revenue increase, and Hawaii Water filed its rebuttal on July 11, 2025. In its rebuttal, Hawaii Water revised its requested revenue to a $4.9 million increase.

<u>Texas Water Service</u>

In June 2024, BVRT filed a general rate case for 5 utilities with the Public Utility Commission of Texas (PUCT). Consumer advocates reviewed and filed their reports in April and May of 2025, and BVRT filed a rebuttal in June of 2025. A settlement was reached and is pending PUCT approval. The initial phase of the new rates was implemented on July 25, 2025.

**LIQUIDITY**

***Cash Flow from Operating Activities***

During the six months ended June 30, 2025, we generated cash flow from operations of $87.4 million compared to $120.9 million for the same period in 2024. The decrease in the first six months of 2025 as compared to the same period in 2024 is primarily due to the receipt of $83.0 million from California's Extended Water and Wastewater Arrearages Payment Program in 2024. This was partially offset by an increase in cash collections in the first six months of 2025 as compared to 2024 due to an increase in customer rates and the recovery of MWRAM and IRMA receivables that were recorded in 2024 due to the resolution of the 2021 CA GRC. Cash generated by operations varies during the year due to customer billings, and timing of collections and contributions to our benefit plans.

During the six months ended June 30, 2025, we made cash contributions of $3.3 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, 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. The 2025 estimated cash contribution to the employee pension plan is expected to be approximately $5.2 million and no cash contributions are expected to be made for the other postretirement benefits plans.

The water business is seasonal. Billed revenue is lower in the cool, wet winter months when less water is typically used compared to the warm, dry summer months when water use is typically the highest. This seasonality results in the possible need for short-term borrowings under our 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, 2025 and 2024, we used $229.5 million and $214.4 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 2025, our utility capital expenditures are estimated to be between $450.0 million and $550.0 million based on the 2024 CA GRC and expected capital needs in the other subsidiaries.

***Cash Flow from Financing Activities***

Net cash provided by financing activities for the six months ended June 30, 2025 was $142.4 million compared to $91.1 million for the same period in 2024. For the six months ended June 30, 2025 and 2024, we paid dividends of $38.1 million and $32.3 million, respectively. For the six months ended June 30, 2025, we issued $1.3 million of Company common stock through our employee stock purchase plan. For the six months ended June 30, 2024, we issued $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 the six months ended June 30, 2025, we also received $10.6 million in initial PFAS settlement proceeds.

For the six months ended June 30, 2025 and 2024, we borrowed $410.0 million and $295.0 million, respectively, on our unsecured revolving credit facilities. We made repayments on our unsecured revolving credit facilities of $255.0 million and $230.0 million during the six months ended June 30, 2025 and 2024, respectively.

The net IRMA, MWRAM, Water Revenue Adjustment Mechanism and Modified Cost Balancing Account receivable balances were $118.4 million and $134.2 million as of June 30, 2025 and 2024, respectively. The receivable balances were primarily financed by Cal Water using short-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-term financing rates.

***Short-term and Long-term Financing***

Short-term liquidity is provided by the Company's revolving credit facility (the Company facility) and the Cal Water revolving credit facility (the Cal Water facility) 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 of Cal Water's borrowings under the Cal Water facility 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 or other business purposes.

As of June 30, 2025 and December 31, 2024, short-term borrowings of $360.0 million and $205.0 million, respectively, were outstanding on the Company and Cal Water facilities.

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' debt portion of the Company's consolidated total capitalization ratio not to exceed 66.7% and an interest coverage ratio of three or more to one (each as defined in the respective credit agreements). As of June 30, 2025, 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 capital 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 capital expenditure requirements. Management expects this trend to continue given our capital expenditure plans for the next five years. Some capital 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 in construction are refundable. 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 5.5% 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 due and punctual payment when due, whether at stated maturity, by acceleration, by notice of prepayment or otherwise, of the principal of, premium, if any, and interest on the bonds. The bonds rank equally among Cal Water's other First Mortgage Bonds.

<u>Dividends</u>

During the six months ended June 30, 2025, our quarterly common stock dividend payments were $0.64 per share, which includes a one-time special dividend in the amount of $0.04 per share, compared to $0.56 per share for the six months ended June 30, 2024. For the full year 2024, the payout ratio was 34.3% 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 30, 2025 meeting, the Company's Board of Directors declared the third quarter dividend of $0.30 per share payable on August 22, 2025, to stockholders of record on August 11, 2025. This was our 322nd consecutive quarterly dividend.

<u>2025 Financing Plan</u>

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, 2025, the Company's and Cal Water's availability on these unsecured revolving lines of credit was $135.0 million and $105.0 million, respectively.

<u>Book Value and Stockholders of Record</u>

Book value per common share was $27.77 at June 30, 2025 compared to $27.49 at December 31, 2024. There were approximately 1,673 stockholders of record for our common stock as of May 12, 2025.

<u>Utility Plant Expenditures</u>

During the six months ended June 30, 2025, utility plant expenditures totaled $229.5 million, including Company-funded projects of $216.7 million and developer-funded projects of $12.8 million. For 2025, we estimate utility capital expenditures to be between $450.0 million and $550.0 million based on the 2024 CA GRC and expected capital needs in the other subsidiaries.

As of June 30, 2025, construction work in progress was $432.0 million. Construction work in progress includes projects that are under construction but not yet complete and placed in service.

<u>PFAS Settlement Proceeds</u>

See Note 9. Commitments and Contingencies for details on settlement proceeds from PFAS manufacturers.

**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 7.8 billion gallons or 14.9% of our total average annual (2023 to 2024) 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 29.6 billion gallons or 56.4% of our total average annual (2023 to 2024) 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, 2025 and 2024, our well pump taxes were $12.1 million and $10.2 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 May 1, 2025, the State of California snowpack water content in California's northern Sierra region for the 2024-2025 water year was 82% of long-term averages (per the California Department of Water Resources). 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 75% and 54%, 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 2025 and thereafter. However, water rationing may be required in future periods, if declared by the state or local jurisdictions. 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.

<u>[**Table of Contents**](#ice5ce5d5e64c4d3e92e80d6098b265e2_7)</u>

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. In May of 2025, the EPA announced its intention to rescind the regulations for four of the PFAS compounds, and to extend the compliance date to 2031. The EPA plans to issue a proposed rule in late 2025 and finalize the rule in the Spring of 2026. 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, 2025, there were no material changes in contractual obligations outside the normal course of business.

**Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK**

There have been no material changes to the Company's quantitative and qualitative disclosures about market risk set forth in Part II, Item 7A of the Company's Annual Report on Form 10-K for the year-ended December 31, 2024 filed with the Securities and Exchange Commission (SEC) on February 27, 2025.

**Item 4. CONTROLS AND PROCEDURES**

(a) Management's 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, 2025. Based on that evaluation, our management including our Chief Executive Officer and Chief Financial Officer, have 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 2025 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.

**Item 1A. RISK FACTORS**

There have been no material changes to the Company's risk factors set forth in Part I, Item 1A of the Company's Annual Report on Form 10-K for the year-ended December 31, 2024 filed with the SEC on February 27, 2025.

**Item 5. OTHER INFORMATION**

(c) Trading Plans
