H2O AMERICA AND SUBSIDIARIES

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

SEPTEMBER 30, 2025

(in thousands, except share and per share data)

Note 1.General

In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all adjustments (consisting only of normal, recurring adjustments) necessary for a fair presentation of the results for the interim periods.

The unaudited interim financial information has been prepared in accordance with accounting principles generally accepted in the United States of America and in accordance with the instructions for Form 10-Q and Rule 10-01 of Regulation S-X promulgated by the Securities and Exchange Commission (“SEC”). The Notes to Consolidated Financial Statements in H2O America’s 2024 Annual Report on Form 10-K, filed with the SEC on February 28, 2025, should be read in conjunction with the accompanying unaudited condensed consolidated financial statements.

In May 2025, the Company changed the corporate name from SJW Group to H2O America and the trading symbol from SJW to HTO on the Nasdaq Global Select Market. H2O America is a holding company that conducts its business through the following wholly owned subsidiaries: San Jose Water Company (“SJWC”), SJWTX Holdings, Inc., SJW Land Company, SJWNE LLC, and National Water Utility Service, LLC (“NWU”). SJWTX Holdings, Inc., is a holding company for its wholly owned subsidiaries, SJWTX, Inc., doing business as The Texas Water Company (“TWC”), Texas Water Operation Services, LLC (“TWOS”) and Texas Water Resources, LLC (“TWR”). SJWNE LLC is the holding company for Connecticut Water Service, Inc. (“CTWS”) whose wholly owned subsidiaries are The Connecticut Water Company (“CWC”), The Maine Water Company (“MWC”), New England Water Utility Services, Inc. (“NEWUS”), and Chester Realty, Inc.

Revenue

Water sales are seasonal in nature and influenced by weather conditions. The timing of precipitation and climatic conditions can cause seasonal water consumption by customers to vary significantly. Due to the seasonal nature of the water business, the operating results for interim periods are not indicative of the operating results for a 12-month period. Revenue is generally higher in the warm, dry summer months when water usage and sales are greater, and lower in the winter months when cooler temperatures and increased precipitation curtail water usage resulting in lower sales.

H2O America’s revenue components are as follows:


	Three months ended September 30,			Nine months ended September 30,
	2025		2024	2025		2024
Revenue from contracts with customers	$	243,522	216,677	$	606,162	539,790
Alternative revenue programs, net	3,996		7,369	6,347		6,847
Other balancing and memorandum accounts and regulatory mechanisms, net	(7,804)		(1,432)	(8,792)		(1,019)
Rental income	836		2,449	2,687		5,001
	$	240,550	225,063	$	606,404	550,619

Nonutility Properties

The major components of nonutility properties as of September 30, 2025 and December 31, 2024, are as follows:


	September 30, 2025		December 31, 2024
Land	$	915	915

Buildings and improvements	399		399

Subtotal	1,314		1,314
Less: accumulated depreciation	101		98
Total	$	1,213	1,216

Fair Value Measurement

The following instruments are not measured at fair value on H2O America’s condensed consolidated balance sheets as of September 30, 2025, but require disclosure of their fair values: cash and cash equivalents, accounts receivable and accounts payable. The estimated fair value of such instruments as of September 30, 2025 approximates their carrying value as reported

Table of Contents

H2O AMERICA AND SUBSIDIARIES

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

SEPTEMBER 30, 2025

(in thousands, except share and per share data)

on the condensed consolidated balance sheets. There have been no changes in valuation techniques during the three and nine months ended September 30, 2025. The fair value of these instruments would be categorized as Level 2 in the fair value hierarchy, with the exception of cash and cash equivalents, which would be categorized as Level 1.

The fair value of H2O America’s long-term debt was $1,603,773 and $1,490,024 as of September 30, 2025 and December 31, 2024, respectively, and was determined using a discounted cash flow analysis, based on the current rates for similar financial instruments of the same duration and creditworthiness of the company. Of the total fair value of long-term debt at September 30, 2025 and December 31, 2024, $1,586,432 and $1,473,393, respectively, would be categorized as Level 2 in the fair value hierarchy and $17,341 and $16,631, respectively, would be categorized as Level 3 in the fair value hierarchy.

CTWS’s additional retirement benefits under the supplemental executive retirement plans and retirement contracts are funded by investment assets held by a Rabbi Trust. The fair value of the money market funds, mutual funds and fixed income investments in the Rabbi Trust was $2,566 and $2,812 as of September 30, 2025 and December 31, 2024, respectively, and are categorized as Level 1 in the fair value hierarchy.

Earnings per Share

Basic earnings per share is calculated using income available to common stockholders, divided by the weighted average number of shares outstanding during the period. Diluted earnings per share is calculated using income available to common stockholders divided by the weighted average number of shares of common stock including both shares outstanding and shares potentially issuable in connection with restricted common stock awards under H2O America’s long-term incentive plans and shares potentially issuable under H2O America’s employee stock purchase plan. For the three months ended September 30, 2025 and 2024, 4,954 and 485 anti-dilutive restricted common stock units were excluded from the diluted earnings per share calculation, respectively. For the nine months ended September 30, 2025 and 2024, 38,734 and 5,289 anti-dilutive restricted common stock units were excluded from the diluted earnings per share calculation, respectively.

New Accounting Standards

The recently issued accounting standards that have not yet been adopted by the company as of September 30, 2025 are as follows:

Standard

Description

Date of Adoption

Application

Effect on the Condensed Consolidated Financial Statements

Accounting Standards Update (“ASU”) 2023-09 “Improvements to Income Tax Disclosures”

The ASU amends certain income tax disclosure requirements, including adding requirements to present the reconciliation of income tax expense computed at the statutory rate to actual income tax expense using both percentages and amounts and providing a disaggregation of income taxes paid. Further, certain disclosures are eliminated, including the current requirement to disclose information on changes in unrecognized tax benefits in the next 12 months.

H2O America will adopt the ASU beginning with its annual financial statements for the year ending December 31, 2025.

Prospective, with retrospective application also permitted.

The standard is expected to only result in updates to disclosure and is not expected to have a material impact on the Company’s financial position and results of operations.

ASU 2024-03 “Disaggregation of Income Statement Expenses”

The ASU requires disclosure, in the notes to the financial statements, of specified information about certain costs and expenses. The ASU requires disclosure of purchases of inventory, employee compensation, depreciation, and intangible asset amortization in interim and annual reporting periods. Further, other amounts already required to be disclosed in accordance with current U.S. GAAP would be included in the same disclosure as the other disaggregation requirements. Additionally, the ASU requires qualitative descriptions of amounts remaining in relevant expense captions that are not separately disaggregated quantitatively as well as disclosure of selling expenses in annual periods and an entity’s definition of selling expenses.

___________________________________

(a)Consists primarily of temporary income tax differences that are flowed through to customers, which will be recovered in future rates as these temporary differences reverse. The company expects to recover regulatory assets related to plant depreciation income tax temporary differences over the lives of the plant assets, which are between 5 to 100 years.

(b)MWRAM is described in the following section.

(c)Consists of debt fair value adjustments recognized through purchase accounting for the completed merger with CTWS in 2019.

(d)Includes deferrals of pension and other postretirement benefit expense and cost of accrued benefits for vacation, and group health insurance.

(e)Primarily relates to Water Rate Adjustment mechanism (“WRA”). WRA and Water Conservation Memorandum Account (“WCMA”) are described in the following section.

(f)Represents costs associated with SJWC’s CAP.

(g)Represents actuarial losses and gains and prior service cost that have not yet been recognized as components of net periodic benefit cost for certain pension and other postretirement benefit plans.

(h)Represents the difference between revenues collected in interim rates in effect as of January 1, 2022 and revenues that would result from rates authorized in SJWC’s 2022 general rate case retroactive to January 1, 2022.

(i)Reflects primarily SJWC’s Full Cost Balancing Account (“FCBA”), which tracks differences in actual water supply costs compared to amounts assumed in base rates, including applicable changes and variations in costs and quantities that affect the overall mix of the water supply.

(j)Other includes other balancing and memorandum accounts and regulatory mechanisms, deferred costs for certain information technology activities, asset retirement obligations, tank painting, well reconditioning and rate case expenses.

(m)On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the “Tax Act”) was signed into law. The Tax Act included a reduction in the federal income tax rate from 35% to 21%. The rate reduction was effective on January 1, 2018 and resulted in a regulatory liability for the excess deferred income taxes. The benefit of amortization of excess deferred income taxes flows back to the customers under current normalization rules and agreed upon methods with the commissions.

(n)Other includes accrued tank painting costs and other regulatory mechanisms.

(o)Primarily relates to the current portion of WRA.

(p)Generally, not earning a return either by interest on the regulatory asset or as a component of rate base at the allowed rate of return.

(q)Primarily relates to legal settlements received by SJWC and CWC from ongoing PFAS water contamination litigation against manufacturers which will be used to offset future costs incurred, recorded as Contributions in Aid of Construction (“CIAC”), or returned to customers through future rates. Water Contamination Litigation Memorandum Account (“WCLMA”) has been established to track net proceeds and costs resulting from water contamination litigation related to SJWC.

SJWC has established balancing accounts for the purpose of tracking the under-collection or over-collection associated with expense changes and the revenue authorized by the California Public Utilities Commission (“CPUC”) to offset those expense changes. SJWC has been authorized for the use of the FCBA to track water supply costs and energy consumption. The MWRAM balancing account 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 would have been in effect.

SJWC also maintains memorandum accounts to track impacts due to catastrophic events, certain unforeseen water quality expenses related to new federal and state water quality standards, energy efficiency, water conservation, water tariffs, and other approved activities or as directed by the CPUC. The WCLMA allows SJWC to track net proceeds and costs resulting from water contamination litigation. The WCMA allows SJWC to track lost revenue, net of related water costs, associated with reduced sales due to water conservation and associated calls for water use reductions, both mandatory and voluntary. SJWC records the lost revenue captured in the WCMA balancing accounts, including amounts related to a 20-basis point reduction in the authorized return on equity per the terms of the WCMA. Applicable drought surcharges collected are used to offset the revenue losses tracked in the WCMA. All balancing accounts and memorandum accounts not included for recovery or refund in the current general rate case will be reviewed by the CPUC in SJWC’s next general rate case or at the time an individual account balance reaches a threshold of 2% of authorized revenue, whichever occurs first. On December 19, 2024, the CPUC issued General Rate Case Decision No. 24-12-077, which approved a recovery of $15,792 in balancing and memorandum accounts from customers through a 12-month surcharge effective January 1, 2025.

CWC has been authorized by the Connecticut Public Utilities Regulatory Authority (“PURA”) to utilize a WRA, a decoupling mechanism, to mitigate risk associated with changes in demand. The WRA is used to reconcile actual water demands with the demands projected in the most recent general rate case and allows the company to implement a surcharge or sur-credit as necessary to recover or refund the revenues approved in the general rate case. The WRA allows the company to defer, as a regulatory asset or liability, the amount by which actual revenues deviate from the revenues allowed in the most recent general rate proceedings.

Note 3.Capitalization

In October 2024, H2O America entered into an equity distribution agreement (the, “Equity Distribution Agreement”) with BofA Securities, Inc., J.P. Morgan Securities LLC, RBC Capital Markets, LLC and Wells Fargo Securities, LLC, pursuant to which the company may offer and sell shares of its common stock, $0.001 par value per share, from time to time in “at-the-market” offerings, having an aggregate gross sales price of up to $200,000. The Equity Distribution Agreement replaced the previous agreement that ended in 2024. For the three and nine months ended September 30, 2025, H2O America issued and sold a total of 492,859 and 2,076,352 shares of common stock, respectively, with a weighted average price of $50.27 and $52.47 per share respectively, and received $24,425 and $108,138 in net proceeds, respectively, under the Equity Distribution Agreement. Since the inception of the Equity Distribution Agreement, H2O America has issued and sold 2,451,865 shares of common stock at a weighted average price of $52.92 for a total net proceeds of $128,307 and has $70,239 of aggregate gross sales price of shares remaining to issue under the Equity Distribution Agreement as of September 30, 2025.

Note 4.Lines of Credit and Long-Term Liabilities

H2O America’s contractual obligations and commitments include senior notes, bank term loans, revenue bonds, state revolving fund loans and other obligations.

Lines of Credit

The weighted average interest rate on short-term borrowings outstanding at September 30, 2025, was 5.10%, compared to 6.08% at December 31, 2024.

As of September 30, 2025, the unused portion of the lines of credit was $243,632.

On July 11, 2025, CTWS repaid the outstanding balance of $25,000 under its credit agreement and concurrently terminated the credit agreement.

SJWC has entered into a $10,000 credit agreement with JPMorgan Chase Bank, N.A., dated June 11, 2025. The credit agreement has a maturity date of June 11, 2026. This line of credit was unused at September 30, 2025.

On September 12, 2025, H2O America and its subsidiaries, SJWC, SJWTX, CWC and MWC, entered into an Amended and Restated Credit Agreement to extend and increase the revolving credit facility with JPMorgan Chase Bank and Wells Fargo Securities, LLC. Pursuant to the amended agreement, the total commitment under the facility was increased from $300,000 to $350,000, and the maturity date was extended from August 2, 2029 to September 12, 2030.

Long-Term Liabilities

On May 23, 2025, MWC submitted an application with the MPUC seeking approval to issue unsecured notes in an amount up to $25,000. The MPUC granted approval on June 17, 2025. On July 10, 2025, MWC issued a promissory note to a national cooperative bank under an existing master loan agreement for a principal amount of $25,000 at a fixed interest rate of 6.70%. The note is an unsecured obligation of MWC due on July 20, 2055. Interest is payable quarterly in arrears on the 20th day of January, April, July and October of each year.

On September 18, 2025, TWC issued a promissory note to a national cooperative bank under an existing master loan agreement for a principal amount of $40,000 at a fixed interest rate of 6.68%. This note is an unsecured obligation of TWC due on September 1, 2055. Interest is payable quarterly in arrears on the 20th day of January, April, July and October of each year.

Note 5.Income Taxes

Income tax expense was $5,791 and $1,928 for the three months ended September 30, 2025 and 2024, respectively. Income tax expense was $13,932 and $7,883 for the nine months ended September 30, 2025 and 2024, respectively. The effective consolidated income tax rates were 11% and 5% for the three months ended September 30, 2025 and 2024, respectively, and 14% and 10% for the nine months ended September 30, 2025 and 2024, respectively. The lower effective tax rate for the three and nine months ended September 30, 2024 was primarily due to a tax accounting method change related to the repairs deductions filed in 2024.

H2O America had unrecognized tax benefits, before the impact of deductions of state taxes, excluding interest and penalties, of $4,093 and $3,707 as of September 30, 2025 and December 31, 2024, respectively. H2O America currently does not expect uncertain tax positions to change significantly over the next 12 months, except in the case of a lapse of the statute of limitations.

On July 4, 2025, Public Law No. 119-21, referred to as the One Big Beautiful Bill Act (“OBBBA”), was signed into law. The OBBBA contains several changes to corporate taxation including the extension of key provisions of the 2017 Tax Cuts and Jobs Act. The legislation has multiple effective dates, with certain provisions effective in 2025 and others phased in through tax year 2027. The legislation may be subject to further clarification and the issuance of interpretive guidance. The Company evaluated the impact of the OBBBA tax legislation in the third quarter of 2025, the period of enactment, and the impact was not material to the provision for income taxes and deferred tax balances.

Note 6.Commitments and Contingencies

H2O America and its subsidiaries are subject to ordinary routine litigation incidental to its business.

In October 2023, CWC, a subsidiary of H2O America, was named as a defendant in a putative class action lawsuit alleging that the water provided by CWC contained contaminants. The case is currently pending in the State of Connecticut Superior Court.

(in thousands, except share and per share data)

CWC intends to vigorously defend itself in this lawsuit. H2O America is unable to provide a reasonable estimate of loss, if any, at this time.

SJWC and CWC are plaintiffs in a lawsuit against manufacturers of certain PFAS compounds for damages, contribution and reimbursement of costs incurred and continuing to be incurred to address the presence of such PFAS compounds in public water supply systems owned and operated by these utility subsidiaries and throughout their respective service areas. The lawsuit is part of Multi-District Litigation (“MDL”) that commenced on December 7, 2018, in the United States District Court for the District of South Carolina. MWC has submitted timely claims as a settlement class member.

On February 8, 2024, the MDL court approved settlements involving defendants The Chemours Company, Corteva, Inc., and DuPont de Nemours, Inc. to resolve claims brought in the MDL against them by public water systems, including SJWC and CWC. On March 29, 2024, the MDL court approved a similar settlement involving defendant 3M Company. On November 22, 2024, the MDL court approved settlements involving defendants Tyco Fire Products LP and BASF Corporation. H2O America is entitled to a portion of the settlements and is monitoring and evaluating the ongoing litigation and settlement activity with the PFAS manufacturers for potential impacts to the various claims that these utility subsidiaries have asserted.

For the three and nine months ended September 30, 2025, the Company received cash proceeds of $14,710 and $21,152, respectively, in connection with a legal settlement with 3M Company related to PFAS contamination. In the third quarter of 2025, the total proceeds of $14,710 were allocated as follows: SJWC received $10,078; CWC received $4,571; and MWC received $61. For the nine months ended September 30, 2025, the total proceeds of $21,152 were allocated as follows: SJWC received $14,497; CWC received $6,477; and MWC received $178, which includes $91 payable to contract operators. The proceeds are compensatory in nature and are intended to reimburse the Company for costs incurred to address the presence of PFAS compounds in public water supply systems or to be refunded to customers through rate reductions, and have been recorded as a regulatory liability subject to regulatory approval.

H2O America is entitled to receive additional cash proceeds from 3M Company in the subsequent nine years, pursuant to the terms of the settlement agreement. In addition, the Company is party to pending settlements with DuPont de Nemours, Inc., Tyco Fire Products LP, and BASF Corporation. Proceeds from these settlements are also expected to be received in 2025 and will be accounted for in a manner consistent with the 3M Company settlement.

H2O America is monitoring and evaluating the ongoing litigation and settlement activity with the PFAS manufacturers for potential impacts to the various claims that these utility subsidiaries have asserted. However, the amount of these additional proceeds is not estimable as of the date of this filing.

Note 7.Benefit Plans

H2O America maintains noncontributory defined benefit pension plans for its eligible employees. SJWC employees hired before March 31, 2008 and CWC and MWC employees hired before January 1, 2009 are entitled to benefits under the pension plans based on the employee’s years of service and compensation. For SJWC employees hired on or after March 31, 2008, benefits are determined using a cash balance formula based upon compensation credits and interest credits for each employee. Starting in 2023, TWC employees are also eligible to participate under SJWC’s cash balance plan. Certain employees hired before March 1, 2012, and covered by a plan merged into the CWC plan in 2013 are also entitled to benefits based on the employee’s years of service and compensation. CTWS employees hired on or after January 1, 2009, are entitled to an additional 1.5% of eligible compensation to their company sponsored savings plan. H2O America does not have multi-employer plans.

In addition, senior management hired before March 31, 2008, for SJWC and January 1, 2009 for CWC, are eligible to receive additional retirement benefits under supplemental executive retirement plans and retirement contracts. SJWC’s senior management hired on or after March 31, 2008, are eligible to receive additional retirement benefits under SJWC’s Cash Balance Executive Supplemental Retirement Plan. The supplemental retirement plans and Cash Balance Executive Supplemental Retirement Plan are non-qualified plans in which only senior management and other designated members of management may participate. H2O America also provides health care and life insurance benefits for retired employees under employer-sponsored postretirement benefits that are not pension plans.

Note 9.Segment Reporting

H2O America’s single reportable segment provides water utility and utility-related services to its customers through H2O America’s subsidiaries, SJWC, CWC, TWC, MWC, and Acequia, which are aggregated and referred to as “Water Utility Services.” Water Utility Services’ activities are water utility operations with both regulated and non-tariffed businesses. Other business activities that do not comprise separately reportable segments primarily include SJWC’s City of Cupertino service concession arrangement operations, property management and investment activity conducted by SJW Land Company and Chester Realty, Inc., contract water and sewer operations and other water-related services provided by NEWUS and are referred to as “Other Services.”

H2O America’s operating segments have been determined based on information used by the chief operating decision maker. H2O America’s chief operating decision makers (“CODM”) include the Chief Executive Officer; the Chief Financial Officer and Treasurer; the President and Chief Operating Officer; the President of Shared Services and Senior Vice President and Chief Administrative Officer; and the Vice President and General Counsel. However, ultimate decision-making authority rests with the Chief Executive Officer. The CODM reviews financial information presented on a consolidated basis that is accompanied by certain disaggregated information about operating revenue, expenses, net income, and total assets. The CODM uses net income to assess the financial performance of the segments and allocate resources (including employees, financial, or capital resources) in the budgeting and forecasting process.

Certain allocated assets, such as goodwill, revenue and expenses have been included in the reportable segment amounts. Certain corporate costs and expenses are not allocated to Water Utility Services or Other Services and are shown separately to reconcile to the applicable consolidated amounts. As previously disclosed, H2O America updated its segment presentation in the fourth quarter of 2024. Accordingly, prior period information has been recast to conform with the current period presentation.

The following tables set forth information relating to H2O America's reportable segment and other business activities:

ITEM 2.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

(Dollar amounts in thousands, except per share amounts and where otherwise noted)

The information in this Item 2 should be read in conjunction with the financial information and the notes thereto included in Item 1 of this Form 10-Q and the condensed consolidated financial statements and notes thereto and the related “Management’s Discussion and Analysis of Financial Condition and Results of Operations” contained in H2O America’s Annual Report on Form 10-K for the year ended December 31, 2024.

This report contains forward-looking statements within the meaning of the federal securities laws relating to future events and future results of H2O America and its subsidiaries that are based on current expectations, estimates, forecasts, and projections about H2O America and its subsidiaries and the industries in which H2O America and its subsidiaries operate and the beliefs and assumptions of the management of H2O America. Actual results may differ materially from those currently anticipated and expressed in such forward-looking statements as a result of a number of factors. For more information about such forward-looking statements, including some of the factors that may affect our actual results, please see our disclosures under “Forward-Looking Statements,” and elsewhere in this Form 10-Q, including Part II, Item 1A under “Risk Factors” as well as the disclosures under Part I, Item 1A in H2O America’s Annual Report on Form 10-K for the year ended December 31, 2024 under “Risk Factors.”

General:

In May 2025, the Company changed the corporate name from SJW Group to H2O America. H2O America is a holding company whose primary business involves ownership of public utilities that provide water and wastewater services, including the production, purchase, storage, purification, distribution, wholesale and retail sale of water. The water utility business of H2O America is conducted through the following wholly owned subsidiaries: San Jose Water Company (“SJWC”), The Connecticut Water Company (“CWC”), The Maine Water Company (“MWC”), SJWTX, Inc. doing business as The Texas Water Company (“TWC”). These subsidiaries provide water service to approximately 407,000 water and wastewater service connections and serve a combined population of over 1.6 million people in California, Connecticut, Maine and Texas. Water utility services provided by these businesses are subject to regulation by the applicable state public utility commissions. These subsidiaries also engage in non-tariffed operations that are not subject to public utility commission regulation, including contract water and sewer operations, maintenance agreements, and antenna site leases.

Together, SJWC, excluding the City of Cupertino (“Cupertino”) service concession arrangement operations, CWC, MWC and TWC are referred to as “Water Utility Services,” which is our single reportable segment.

Other business activities that are not separately reportable segments are SJWC’s Cupertino service concession arrangement operations, Texas Water Operation Services, LLC (“TWOS”), Texas Water Resources, LLC (“TWR”), New England Water Utility Services, Inc. (“NEWUS”), SJW Land Company and Chester Realty, Inc. and are collectively referred to as “Other Services.”

Business Strategy for Water Utility Services:

H2O America focuses its business initiatives in three strategic areas:

(1)Investing in regional regulated water utility operations to support the health, safety and quality of life of our customers;

(2)Regional non-tariffed water utility-related services provided in accordance with the guidelines established by applicable state public utility commissions; and

(3)Out-of-region water and utility-related services.

As part of our pursuit of the above three strategic areas, we consider from time to time opportunities to acquire businesses and assets. However, we cannot be certain we will be successful in identifying and consummating any strategic business combinations or acquisitions relating to such opportunities. In addition, the execution of our business strategy will expose us to different risks than those associated with the current utility operations. We expect to incur costs in connection with the execution of this strategy and any integration of an acquired business could involve significant costs, the assumption of certain known and unknown liabilities related to the acquired assets, the diversion of management’s time and resources, the potential for a negative impact on our financial position and operating results, entering markets in which we have no or limited direct prior experience and the potential loss of key employees of any acquired company. Any strategic combination or acquisition we decide to undertake may also impact our ability to finance our business, affect our compliance with regulatory requirements, and impose additional burdens on our operations. Any businesses we acquire may not achieve sales, customer growth and projected profitability that would justify the investment. Any difficulties we encounter in the integration process, including the

Table of Contents

integration of controls necessary for internal control and financial reporting, could interfere with our operations, reduce our operating margins and adversely affect our internal controls. H2O America cannot be certain that any transaction will be successful or that it will not materially harm operating results or our financial condition.

As previously disclosed, H2O America updated its segment presentation in the fourth quarter of 2024. Accordingly, prior period information has been recast to conform with the current period presentation.

As previously disclosed, H2O America, through its indirect subsidiary, TWC, is set to acquire regulated systems owned by Quadvest L.P. for $483,600, and TWOS will acquire systems owned by Quadvest Wholesale LLC for $56,400. Please see Note 10 “Acquisitions” for further discussion. On the completion of this acquisition, Quadvest will bring operational scale, a strong development pipeline, and increased exposure to one of America’s fastest growing regions, Houston, TX. Quadvest brings a strong legacy of local relationships and reliable service. It has been providing water and sewer service in Southeast Texas for nearly 50 years through its operating entities.

Critical Accounting Estimates:

The discussion and analysis of our financial condition and results of operations is based on the accounting estimates used and disclosed in our 2024 consolidated financial statements and accompanying notes that were prepared in accordance with accounting principles generally accepted in the United States of America and included as part of our Annual Report on Form 10-K for the year ended December 31, 2024, that was filed with the Securities and Exchange Commission on February 28, 2025.

Our critical accounting estimates are described in Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our Annual Report on Form 10-K for the year ended December 31, 2024. Our significant accounting policies are described in the notes to the 2024 consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2024. There have been no changes to critical accounting estimates or significant accounting policies during the three and nine months ended September 30, 2025.

New Accounting Pronouncements:

See Note 1 of “Notes to Unaudited Condensed Consolidated Financial Statements” for a discussion of new accounting pronouncements.

Results of Operations:

Water sales are seasonal in nature and are influenced by weather conditions. The timing of precipitation and climatic conditions can cause seasonal water consumption by customers to vary significantly. Due to the seasonal nature of the water business, the operating results for interim periods are not indicative of the operating results for a 12-month period. Revenue is generally higher in the warm, dry summer months when water usage and sales are greater, and lower in the winter months when cooler temperatures and increased precipitation curtail water usage and sales.

Overview

H2O America’s consolidated net income for the three months ended September 30, 2025 was $45,132, an increase of $6,480, or 17%, from $38,652 for the same period in 2024. H2O America’s consolidated net income for the nine months ended September 30, 2025 was $86,358, an increase of $15,311, or approximately 22%, from $71,047 for the same period in 2024. The increase in net income for the three and nine months ended September 30, 2025 was primarily driven by rate increases in California and Connecticut. These factors were offset by higher water production expenses and increased other operating expenses as discussed below.

Operating Revenue

H2O America has a single reportable segment, referred to as “Water Utility Services.” All other business activities not separately reportable are included in “Other Services.” Operating revenue for the Water Utility Services reportable segment and Other Services was as follows:

Sources of Water Supply

SJWC’s water supply consists of groundwater from wells, surface water from watershed run-off and diversion, reclaimed water, and imported water purchased from Santa Clara Valley Water District (“Valley Water”) under the terms of a master contract with Valley Water expiring in 2051. During normal rainfall years, purchased water provides approximately 40% to 50% of SJWC’s annual production. An additional 40% to 50% of its water supply is pumped from the underground basin which is subject to a groundwater extraction charge paid to Valley Water. Surface supply, which during a normal rainfall year satisfies about 6% to 8% of SJWC’s annual water supply needs, provides approximately 1% of its water supply in a dry year and approximately 14% in a wet year. In dry years, the decrease in availability of water from surface run-off and diversion and the corresponding increase in purchased and pumped water increases production expenses substantially. The opposite is also true where water production expenses decrease in wet years. In both instances, the impacts of surface water, purchased water, groundwater charges and purchased power are tracked in SJWC’s FCBA authorized by the CPUC for cost recovery limiting the impact on operating expenses in the current period.

For the nine months ended September 30, 2025, water conditions remained positive across the State of California. As a result of the improved conditions, beginning in the first quarter of 2025, the California Department of Water Resources (“DWR”) announced an increase in the State Water Project allocation from 35% to 40% of the contract amount and the U.S. Bureau of Reclamation kept the Central Valley Project allocation at 75% during the same period. The DWR further announced an increase in the State Water Project allocation from 40% to 50% of the contract amount during the second quarter of 2025, while the U.S. Bureau of Reclamation’s Central Valley Project allocation increased from 75% to 80% during the same period. Water allocations for the State Water Project and the Central Valley Project remained at 50% and 80%, respectively, during the third quarter of 2025. On October 1, 2025, Valley Water’s 10 reservoirs were at 60% of restricted capacity, with 12.3 billion gallons of water in storage. Valley Water’s largest reservoir, Anderson, remained drained for a dam seismic retrofit project. Valley Water also reported that managed groundwater recharge from January 2025 to September 2025 in the Santa Clara Plain was 117% of the five-year average. The groundwater level in the Santa Clara Plain is approximately 14 feet lower than in September 2024. According to Valley Water, the projected total groundwater storage at the end of 2025 is expected to be in the Normal Stage of the Water Shortage Contingency Plan.

As of September 30, 2025, SJWC’s Lake Elsman was at 73% of capacity with 1.5 billion gallons of water, approximately 168.1% of the five-year seasonal average. In addition, the rainfall at SJWC’s Lake Elsman was measured at 0.75 inches for the period from July 1, 2025 through September 30, 2025, which is 202.7% of the five-year average. SJWC’s Montevina Water Treatment Plant treated 1.8 billion gallons of water through the third quarter of 2025, which is 103.4% of the five-year average. SJWC’s Saratoga Water Treatment Plant treated 40 million gallons of water through the third quarter of 2025, which is 78.5% of the five-year average. The Saratoga Water Treatment Plant was taken out of service during the second quarter of 2025 due to a lack of surface water runoff and remained offline during the third quarter. SJWC believes that its various sources of water supply will be sufficient to meet customer demand in 2025.

California faces long-term water supply challenges. SJWC actively works with Valley Water to meet these challenges by continuing to educate customers on responsible water use practices and conducting long-range water supply planning. Valley Water’s 15% voluntary call for conservation and certain watering and water waste rules established in 2023 are still in place for 2025. The call for continued conservation is due to a major storage reservoir currently offline for seismic retrofits.

CWC’s water sources vary among the individual systems, but overall, approximately 60% of the total dependable yield comes from surface water supplies and 40% from wells. In addition, CWC has water supply agreements to supplement its water supply with the South Central Connecticut Regional Water Authority and The Metropolitan District that expire in 2058 and 2053, respectively. CWC believes that it will be able to meet customer demand for the remainder of 2025 with its existing water supply which consists of groundwater from wells, surface water in reservoirs and purchased water treated by neighboring water utilities.

TWC’s water supply consists of groundwater from wells and purchased treated and untreated raw water from local water agencies. TWC has long-term agreements with the Guadalupe-Blanco River Authority (“GBRA”), which expire in 2037, 2040, 2044 and 2050. The agreements, which are take-or-pay contracts, provide TWC with an aggregate of approximately 7,602 acre-feet of water per year from Canyon Lake at prices that may be adjusted periodically by GBRA. TWC also has raw water supply agreements with the Lower Colorado River Authority and West Travis County Public Utility Agency expiring in 2059 and 2046, respectively, to provide for 350 acre-feet of water per year from Lake Austin and the Colorado River, respectively, at prices that may be adjusted periodically by the agencies. Forty active production wells located in a Comal Trinity Groundwater Conservation District, a regulated portion of the Trinity aquifer, are charged a groundwater pump tax based upon usage. TWC also owns eight wells and the associated water rights of KT Water Resources, LLC. These wells have been projected to yield at least 6,000 acre-feet per year. Development of the KT Water System continues.

Despite ongoing drought conditions in the Texas service area, which have led to water usage restrictions for customers, TWC expects to meet customer demand for the remainder of 2025 based on current conditions. This expectation is supported by its

Table of Contents

diversified water supply portfolio, including groundwater wells, surface water, and purchased treated water from the GBRA. To ensure long-term system resilience, significant capital investments in transmission mains, storage facilities, and new supply sources are planned for 2025 and beyond.

Water sources at MWC vary among the individual systems, but overall, approximately 90% of the total dependable yield comes from surface water supplies and 10% from wells. MWC has a water supply agreement with the Kennebec Water District expiring in 2040. MWC believes that it will be able to meet customer demand for the remainder of 2025 with its existing water supply which consists of groundwater from wells, surface water in reservoirs and rivers, and purchased water treated by neighboring water utilities.

The following table presents the change in sources of water supply:


	Three months ended September 30,		Increase/ (decrease)	% of Total Change		Nine months ended September 30,		Increase/ (decrease)	% of Total Change
	2025	2024				2025	2024

	15.5	15.8	(0.3)	(2)	%	38.1	37.3	0.8	2	%

The changes in the source of supply mix were consistent with the changes in the water production expenses.

Water Production Expenses

The increase in water production expenses of $2,614 for the three months ended September 30, 2025, compared to the same period in 2024, was primarily attributable to increases in average per unit costs for purchased water and groundwater extraction, and decreases in availability of lower cost surface water, partially offset by decreases resulting from regulatory adjustments through SJWC’s FCBA and decreases in production volume and usage.

The change in water production expenses of $20,186 for the nine months ended September 30, 2025, compared to the same period in 2024, was primarily attributable to increases in average per unit costs for purchased water and groundwater extraction, and increases in production volume and usage, and decreases in availability of lower cost surface water, partially offset by decreases resulting from regulatory adjustments through SJWC’s FCBA.

SJWC was notified by Valley Water that the unit prices of purchased water and the groundwater extraction charge were increased by 9% and 10%, respectively, effective July 1, 2025. Effective July 1, 2024, Valley Water increased the unit price of purchased water by approximately 12% and the groundwater extraction charge by approximately 13% for SJWC.

Other Operating Expenses

Operating expenses, excluding water production expenses, increased $6,599 for the three months ended September 30, 2025, compared to the same period in 2024. The increase was primarily attributable to increases in general and administrative expenses for pension costs, salaries and wages, increases in depreciation and amortization for new utility plant placed in service and inflationary increases, partially offset by higher allocations to construction activities.

Operating expenses, excluding water production expenses, increased $18,047 for the nine months ended September 30, 2025, compared to the same period in 2024. The increase was primarily attributable to an increase in general and administrative expenses related to customer credit losses as a result of funds received from the California Extended Water and Wastewater Arrearage Payment Program in the prior year, and increases in acquisition costs, salaries and wages, pension costs, insurance and contracted work.

Other (Expense) Income

For the three months ended September 30, 2025, compared to the same period in 2024, the change in other (expense) income was primarily due to increases in pension non-service credit, higher income from the equity portion of the Allowance for Funds Used During Construction (AFUDC), partially offset by an increase in interest expense.

For the nine months ended September 30, 2025, compared to the same period in 2024, the change in other (expense) income was primarily due to higher income from the equity portion of the AFUDC, and an increase in pension non-service credit, partially offset by an increase in interest expense.

Table of Contents

Provision for Income Taxes

For the three and nine months ended September 30, 2025, compared to the same period in 2024, income tax expense increased $3,863 and $6,049, respectively. The increase in income tax expense for the three and nine months ended September 30, 2025 was primarily due to a higher pre-tax income in 2025. In addition, the cumulative catch-up adjustment relating to the accounting method change filed in 2024 resulted in a lower tax expense in the third quarter of 2024. The effective consolidated income tax rates were 11% and 5% for the three months ended September 30, 2025 and 2024, respectively, and 14% and 10% for the nine months ended September 30, 2025 and 2024, respectively.

Regulation and Rates

Almost all of the operating revenue of H2O America results from the sale of water at rates authorized by the subsidiaries’ respective state utilities commissions. The state utilities commissions set rates that are intended to provide revenue sufficient to recover operating expenses and the opportunity to achieve a specified return on common equity. The timing of rate decisions could have an impact on the results of operations.

Please also see Note 2 of “Notes to Condensed Consolidated Financial Statements.”

California Regulatory Affairs

On December 19, 2024, the CPUC approved a final decision, Decision No. 24-12-077, in SJWC’s General Rate Case Application No. 24-01-001, for rate increases of $21,318 or 3.91% in 2025, $14,432 or 2.55% in 2026, and $17,373 or 2.98% in 2027. The decision also provides a three-year capital budget of $450,000 and recovery of $15,792 in balancing and memorandum accounts.

On December 18, 2024, SJWC, along with three other California water utilities, filed a joint request for a one-year deferment on the cost of capital filings which would otherwise be due on May 1, 2025. Postponing the filing a year alleviates administrative processing costs on the utilities as well as the CPUC staff and provides relief for both CPUC and utility resources already strained by numerous other proceedings. The request was conditioned on leaving the current Water Cost of Capital Mechanism in place such that any adjustments will be made to the respective utilities’ cost of capital during the one-year deferment based on the mechanism. The request was approved on January 14, 2025.

Texas Regulatory Affairs

TWC filed its application to establish a System Improvement Charge (“SIC”) with the Public Utilities Commission of Texas (“PUCT”) under Docket No. 54430 on December 30, 2022. SIC filings are used to include certain utility plant additions made since 2020, thereby increasing revenue and avoiding the immediate need for a general rate case. TWC’s SIC application included capital investments that improve its water and wastewater systems to better serve its customers. On March 21, 2024, the PUCT filed the final order approving TWC’s request to implement its SIC which applies to certain customers. As a result of this final order, TWC increased its annual water revenue by $1,574 and its annual sewer revenues by $28 on an annual basis.

On September 12, 2024, TWC filed its application to amend its SIC with the PUCT under Docket No. 56974. Its amended SIC applies to all customers and increases its annual water revenue by $3,915 and its annual sewer revenue by $195, in addition to the original SIC filed with the PUCT under Docket No. 54430 on December 30, 2022. On May 15, 2025, the PUCT filed the final order approving TWC’s amended SIC application.

On October 6, 2025, TWC filed its second application to amend its SIC with the PUCT under Docket No. 58739. If approved as requested, TWC’s annual water revenue will increase by $4,746 and increase its annual sewer revenue by $317. TWC expects to receive the ruling on the administrative completeness of the application by October 31, 2025.

Additionally, TWC is required to file a general rate case on or before March 21, 2028. Notwithstanding any SIC filing, TWC will continue to file its annual adjustments for the Water Pass-through Charges (“WPC”) for Canyon Lake, Deer Creek, Kendall West, Clear Water Estates, and Saddleridge customers. All water supply cost increases are recoverable when the next annual WPC adjustment for each system is filed.

Maine Regulatory Affairs

On October 25, 2024, MWC filed an application with MPUC to adjust customer rates in the Camden Rockland division. The proposal requested an increase in annual revenues of approximately $1,057, or 15.9%, over current authorized revenues. On June 27, 2025, MPUC approved a settlement stipulation, authorizing an increase in rates of $865, or 13.00%, with an effective date of July 1, 2025.

On December 31, 2024, MWC filed for a unified tariff across its 10 separate rate divisions. A decision in this case is expected in the first quarter of 2026.

On April 15, 2025, MWC filed a Water Infrastructure Surcharge in both the Oakland and Biddeford Saco divisions. The combined requested surcharge is 3.00% or $547. The MPUC issued an order approving the surcharges on June 24, 2025, with an effective date of July 1, 2025.

Legislative Document 241, An Act to Authorize the Public Utilities Commission to Approve Rate Adjustments for Low-Income Water Utility Ratepayers, was approved by the Maine Legislature and signed into law by the Governor on May 29, 2025. As part of the unified tariff proceeding, MWC has proposed a rate adjustment mechanism for qualifying residential customers which as a result of this recently passed legislation can now be considered as part of the filing originally submitted in December 2024 .

Cash Flow from Operating Activities

During the nine months ended September 30, 2025, H2O America generated cash flows from operations of $181,283, compared to $154,066 for the same period in 2024. Cash flow from operations is primarily generated by net income from revenue producing activities, adjusted for non-cash expenses for depreciation and amortization, deferred income taxes, stock-based compensation, allowance for equity funds used during construction, and changes in working capital items. Cash flow from operations increased by $27,217 for the nine months ended September 30, 2025 from the same period in the prior year. This increase was primarily the result of a combination of the following factors: (1) favorable changes in taxes receivable/payable of $12,348 primarily due to a tax accounting method change filed in 2024 and tax refunds, (2) proceeds from the PFAS litigation settlement of $6,640, and (3) an increase of $6,262 attributable to changes in regulatory assets and liabilities primarily due to SJWC General Rate Case (GRC) surcharge.

Table of Contents

As of September 30, 2025, Water Utility Services’ write-offs for credit losses represented less than 1% of its total revenue, unchanged from September 30, 2024. Management believes that the collection rate will continue to improve for its accounts receivables as service disconnections return to normal operations.

Cash Flow from Investing Activities

Net cash used in investing activities for the nine months ended September 30, 2025, increased by $136,864 from the same period in the prior year, primarily as a result of (1) an increase in company-funded utility capital expenditures of $98,794 and (2) a reduction in proceeds received from the sale of real estate investments in 2025 by $37,868 attributable to the completed sale of Tennessee properties in 2024.

Cash Flow from Financing Activities

Net cash provided by financing activities for the nine months ended September 30, 2025 increased by $115,603 from the same period in the prior year, primarily as a result of (1) an increase in net borrowings on the lines of credit of $86,394, (2) an increase in net proceeds from common stock equity offerings of $44,829, (3) an increase attributable to lower repayments on long-term debt of $39,746, (4) an increase in cash receipts of advances and contributions in aid of construction of $21,362, (5) proceeds from PFAS litigation settlement of $14,421, offset by (6) a decrease in proceeds of $85,329 from the issuance of long-term debt.

Budgeted Capital Expenditures

Water Utility Services’ estimated utility capital expenditures for 2025, exclusive of capital expenditures financed by customer contributions and advances, are anticipated to be approximately $473,000, updated from the previously reported budgeted expenditures of $451,000. The budgeted capital expenditures exclude capitalizable costs of $13,000 forecasted in 2025 that are associated with cloud-based computing arrangements. As of September 30, 2025, $351,069, or 74%, of the $473,000 has been invested.

Water Utility Services’ capital expenditures are incurred in connection with normal upgrading and expansion of existing facilities and to comply with environmental regulations. Over the next five years, Water Utility Services expects to incur approximately $1,900,000 in capital expenditures, which includes replacement of pipes and mains, maintaining water systems, and installing approximately $300,000 in PFAS treatment. A significant portion of this amount is subject to future respective state regulatory utility commissions’ approval. Capital expenditures have the effect of increasing utility plant rate base on which Water Utility Services earns a return. Water Utility Services’ actual capital expenditures may vary from their projections due to changes in the expected demand for services, weather patterns, actions by governmental agencies, and general economic conditions. Total additions to utility plant normally exceed company-financed additions as a result of new facilities construction funded with advances from developers and contributions in aid of construction.

The Water Utility Services’ distribution systems were constructed during the period from the early 1900’s through today. Expenditure levels for renewal and modernization will occur as the components reach the end of their useful lives. In most cases, replacement costs will significantly exceed the original installation costs of the retired assets due to increases in the costs of goods and services and increased regulation.

In addition to these capital expenditures, Water Utility Services expects to incur approximately $105,000 over the next five years, including $13,000 in 2025, in capitalizable costs associated with cloud-based computing arrangements. For the nine months ended September 30, 2025, Water Utility Services’ incurred $6,741 in cloud-based computing expenses.

Sources of Capital:

H2O America’s ability to finance future construction programs and sustain dividend payments depends on its ability to maintain or increase internally generated funds and attract external financing. The level of future earnings and the related cash flow from operations is dependent, in large part, upon the timing and outcome of regulatory proceedings.

Short-term Financing Agreements

H2O America and its subsidiaries have unsecured line of credit agreements where borrowings are used to refinance existing debt, for working capital, and for general corporate purposes.

SJWC has entered into a $10,000 credit agreement with JPMorgan Chase Bank, N.A., dated June 11, 2025. The credit agreement has a maturity date of June 11, 2026.

For the nine months ended September 30, 2025, the cost of borrowing on the lines of credit averaged 5.42% compared to 6.53% in the same period in 2024.

All of H2O America’s and subsidiaries’ lines of credit contain customary representations, warranties and events of default, as well as certain restrictive covenants customary for facilities of this type, including restrictions on indebtedness, liens, acquisitions and investments, restricted payments, asset sales, and fundamental changes. All of the lines of credit also include certain customary financial covenants such as a funded debt to capitalization ratio and a minimum interest coverage ratio. As of September 30, 2025, H2O America and its subsidiaries were in compliance with all covenants on their lines of credit.

Long-term Financing Agreements

The debt and credit agreements of H2O America and its subsidiaries contain various financial and other covenants. Non-compliance with these covenants could result in accelerated due dates and termination of the agreements. In addition, the credit agreements contain customary representations and warranties and are subject to customary events of default, which may result in the outstanding debt becoming immediately due and payable. As of September 30, 2025, H2O America and its subsidiaries were in compliance with all covenants in their long-term debt agreements.

On May 23, 2025, MWC submitted an application with MPUC seeking approval to issue unsecured notes in an amount up to $25,000. The MPUC granted approval on June 17, 2025. On July 10, 2025, MWC issued a promissory note to a national cooperative bank under an existing master loan agreement for a principal amount of $25,000 at a fixed interest rate of 6.70%. The note is an unsecured obligation of MWC due on July 20, 2055. Interest is payable quarterly in arrears on the 20th day of January, April, July and October of each year.

Equity Financing Arrangements

In October 2024, H2O America entered into an equity distribution agreement (the “Equity Distribution Agreement”) with BofA Securities, Inc., J.P. Morgan Securities LLC, RBC Capital Markets, LLC and Wells Fargo Securities, LLC, pursuant to which the company may offer and sell shares of its common stock, $0.001 par value per share, from time to time in “at-the-market” offerings, having an aggregate gross sales price of up to $200,000. The Equity Distribution Agreement replaced the previous agreement that ended in 2024. For the three and nine months ended September 30, 2025, H2O America issued and sold a total of 492,859 and 2,076,352 shares of common stock, respectively, with a weighted average price of $50.27 and $52.47 per share respectively, and received $24,425 and $108,138 in net proceeds, respectively, under the Equity Distribution Agreement. Since the inception of the Equity Distribution Agreement, H2O America has issued and sold 2,451,865 shares of common stock at a

Table of Contents

weighted average price of $52.92 for a total net proceeds of $128,307 and has $70,239 of aggregate gross sales price of shares remaining to issue under the Equity Distribution Agreement as of September 30, 2025.

Credit Rating

The condition of the capital and credit markets or the strength of financial institutions could impact H2O America’s ability to draw on its lines of credit, issue long-term debt, sell its equity or earn interest income. In addition, government policies, the state of the credit markets and other factors could result in increased interest rates, which would increase H2O America’s cost of capital. While our ability to obtain financing will continue to be a risk, we believe that based on our 2025 and 2024 activities we will continue to have access to the external funding sources necessary to implement our ongoing capital investment programs in the future. On July 15, 2025, Standard & Poor’s Ratings Services revised the outlook for H2O America, CTWS and CWC from stable to negative following the announcement of the Quadvest acquisition.

ITEM 3.QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

H2O America is subject to market risks in the normal course of business, including changes in interest rates, pension plan asset values, and equity prices. The exposure to changes in interest rates can result from the issuance of debt and short-term funds obtained through the company’s variable rate lines of credit. H2O America’s subsidiaries sponsor noncontributory pension and other post-retirement plans for its employees. Pension and other post-retirement costs and the funded status of the plans may be affected by a number of factors including the discount rate, mortality rates of plan participants, investment returns on plan assets, and pension reform legislation.

H2O America has no derivative financial instruments, financial instruments with significant off-balance sheet risks, or financial instruments with concentrations of credit risk.

ITEM 4.CONTROLS AND PROCEDURES

H2O America’s management, with the participation of its Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of H2O America’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, the “Exchange Act”), as of the end of the period covered by this report. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that H2O America’s disclosure controls and procedures as of the end of the period covered by this report have been designed and are functioning effectively to provide reasonable assurance that the information required to be disclosed by H2O America in the reports that it files or submits under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. H2O America believes that a control system, no matter how well designed and operated, cannot provide absolute assurance that the objectives of the control system are met, and no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within a company have been detected.

There has been no change in internal control over financial reporting during the third fiscal quarter of 2025 that has materially affected, or is reasonably likely to materially affect, the internal controls over financial reporting of H2O America.

PART II. OTHER INFORMATION

ITEM 1.LEGAL PROCEEDINGS

H2O America is subject to ordinary routine litigation incidental to its business.

SJWC and CWC are plaintiffs in a lawsuit against manufacturers of certain PFAS compounds for damages, contribution and reimbursement of costs incurred and continuing to be incurred to address the presence of such PFAS compounds in public water supply systems owned and operated by these utility subsidiaries and throughout their respective service areas. The lawsuit is part of MDL, that commenced on December 7, 2018, in the United States District Court for the District of South Carolina. MWC has submitted timely claims as a settlement class member.

On February 8, 2024, the MDL court approved settlements involving defendants The Chemours Company, Corteva, Inc., and DuPont de Nemours, Inc. to resolve claims brought in the MDL against them by public water systems, including SJWC and CWC. On March 29, 2024, the MDL court approved a similar settlement involving defendant 3M Company. On November 22, 2024, the MDL court approved settlements involving defendants Tyco Fire Products LP, and BASF Corporation. H2O America is entitled to a portion of the settlements and is monitoring and evaluating the ongoing litigation and settlement activity with the PFAS manufacturers for potential impacts to the various claims that these utility subsidiaries have asserted.

H2O America is entitled to receive additional cash proceeds from 3M Company over the subsequent nine years, pursuant to the terms of the settlement agreement. In addition, the Company is party to pending settlements with DuPont de Nemours, Inc., Tyco Fire Products LP, and BASF Corporation. Proceeds from these settlements are also expected to be received in 2025 and will be accounted for in a manner consistent with the 3M Company settlement.

ITEM 1A.RISK FACTORS

In addition to the other information set forth in this report, you should carefully consider the factors discussed in “Risk Factors” in H2O America’s annual report on Form 10-K for the year ended December 31, 2024 and our other public filings, which could materially affect our business, financial condition or future results. Other than the risk factors listed and referenced to below, there have been no material changes from risk factors previously disclosed in “Risk Factors” in H2O America’s annual report on Form 10-K for the year ended December 31, 2024.

The following discusses certain risk factors relating to the proposed transactions with Quadvest, L.P., a Texas limited partnership, (“Quadvest Retail”) and Quadvest Wholesale, LLC, a Texas limited liability company (“Quadvest Wholesale” and together with Quadvest Retail, “Quadvest”) and does not include all of the risk factors associated with the proposed transactions and H2O America after the proposed transactions.

Our proposed transactions with Quadvest are subject to the receipt of consents and clearances from regulatory authorities that may impose conditions that could have an adverse effect on H2O America or, if not obtained, could prevent completion of the proposed transactions.

Completion of the proposed transactions is contingent upon, among other things, the receipt of all required regulatory approvals, which consist of compliance with and filings and the applicable waiting period under the Hart Scott-Rodino Antitrust Improvements Act, compliance with and applications for permits with state and municipal agencies and consent required by the PUCT for the transfer of Quadvest’s water and sewer utility business (the “Regulated Business”).

The terms and conditions of the approvals that are granted by such governmental entities and regulatory authorities may impose requirements, limitations, costs, or place restrictions on the conduct of H2O America’s business. The asset purchase agreements

Table of Contents

may require H2O America to comply with conditions imposed by regulatory entities and, in certain circumstances, either company may refuse to close the proposed transactions on the basis of regulatory conditions imposed. There can be no assurance that regulators will not impose conditions, terms, obligations or restrictions or that such conditions, terms, obligations or restrictions will not have the effect of delaying completion of the proposed transactions or imposing additional material costs on or materially limiting the revenues of H2O America following the proposed transactions. Additionally, H2O America cannot provide assurance that any such conditions, terms, obligations or restrictions will not result in the delay or abandonment of the proposed transactions, or the consummation of the proposed transactions on terms different than those contemplated by the asset purchase agreements.

The length of the regulatory approval process required by the PUCT, which may be extended beyond its current estimates, may reduce or eliminate the benefits to be achieved under the proposed transactions.

As a condition to the consummation of the proposed transactions, the sale of the Regulated Business must be approved by the PUCT. While we expect the transaction to receive PUCT approval by mid-2026, the exact timeline for this approval process is unknown and may not occur until later, if at all.

In addition to the required regulatory clearances, the proposed transactions are subject to a number of other conditions beyond H2O America’s control that may prevent, delay or otherwise materially adversely affect its completion. We cannot predict whether and when these other conditions will be satisfied. Furthermore, the requirements for obtaining the required clearances and approvals could delay the completion of the proposed transactions for a significant period of time or prevent them from occurring. Any delay in completing the proposed transactions could cause H2O America to not realize, or to be delayed in realizing, some or all of the benefits that we expect to achieve if the proposed transactions are successfully completed within the expected time frame. Failure to achieve these anticipated benefits within the expected time frame could result in increased costs and/or lower-than-expected revenues or income generated by H2O America after the completion of the proposed transactions.

We may be unable to successfully integrate Quadvest’s business with ours and realize the anticipated benefits of the acquisition, which could negatively impact the future business and financial results of H2O America.

The anticipated benefits expected from the proposed transactions are based on projections and assumptions about the combined Quadvest and H2O America businesses, which may not materialize as expected or which may prove to be inaccurate. Achieving the benefits of the proposed transactions will depend, in part, on H2O America’s ability to integrate the business and operations of Quadvest successfully and efficiently with our business. The challenges involved in this integration, which will be complex and time-consuming, include the following:

•successfully managing relationships with our combined customer base and retaining Quadvest’s customers;

•the ability to successfully integrate Quadvest’s business with ours in a manner that permits H2O America to achieve the synergies and other benefits anticipated to result from the proposed transactions;

•integrating complex systems, operating procedures, regulatory compliance programs, technology, networks, and other assets of Quadvest and H2O America in a manner that minimizes any adverse impact on customers, suppliers, employees, and other constituencies;

•diversion of the attention of the management and other key employees of Quadvest and H2O America;

•integrating the workforces of Quadvest and H2O America while maintaining focus on providing clean, high quality water and exceptional service;

•disruption of, or the loss of momentum in, the ongoing business of H2O America;

•liabilities that are significantly larger than we currently anticipate and unforeseen increased expenses or delays associated with the proposed transactions, including transition costs to integrate the businesses of Quadvest and H2O America, that may exceed the costs that we currently anticipate; and

•the increased scale of our operations resulting from the proposed transactions.

If we do not successfully manage these issues and the other challenges inherent in integrating Quadvest, then we may not achieve the anticipated benefits of the proposed transactions and our business, financial condition and results of operations could be materially adversely affected.

The fair market value determination made in connection with the PUCT approval process may result in a lower realized value for the Regulated Business.

As a part of the application process, H2O America and Quadvest will submit appraisal reports to the PUCT for approval of a fair market value of the assets of the Regulated Business (the “FMV”) which H2O America may use for purposes of setting water rates in Texas by a separate application filed with the PUCT following the consummation of the proposed transactions. If the approved FMV is lower than H2O America anticipates, H2O America may, under certain circumstances, still be required to

Table of Contents

consummate the proposed transactions (subject to the satisfaction of all other conditions contained in the asset purchase agreements) but may not be able to realize the full expected value of the Regulated Business in rates following the consummation of the proposed transactions.

Failure to complete the proposed transactions as currently contemplated or at all could negatively impact the stock price, business operations and financial results of H2O America.

Completion of the proposed transactions is not assured and is subject to risks, including the risks that approval of the proposed transactions by governmental entities will not be obtained or that certain other closing conditions will not be satisfied. If the proposed transactions are not completed, or are completed on different terms than as contemplated by the asset purchase agreements, the ongoing businesses and financial results of H2O America may be adversely affected and H2O America will be subject to several risks, including the following:

•having to pay certain significant costs relating to the proposed transactions without receiving the benefits of the proposed transactions, including, in certain circumstances, payment of a termination fee;

•reputational harm due to the adverse public perception of any failure to successfully complete the proposed transactions; and

•H2O America’s management having focused on the proposed transactions instead of on conducting its day-to-day business and operational matters and pursuing other opportunities that could have been beneficial to the companies.

Any delay in the completion of the proposed transactions, any uncertainty about the completion of the proposed transactions on terms other than those contemplated by the asset purchase agreements and any failure to complete the proposed transactions could adversely affect the business, financial results and stock price of H2O America.

The asset purchase agreements with Quadvest may be terminated in certain circumstances, which would result in the benefits of the proposed transactions not being realized, and under certain circumstances, we may be required to pay a termination fee.

Either H2O America or Quadvest may terminate the asset purchase agreements under certain circumstances, including if the proposed transactions have not been consummated by January 7, 2027 (unless such date is extended to a date mutually agreed to by the parties to obtain regulatory approval under certain circumstances, which could be up to an additional eighteen months). However, this termination right will not be available to a party if such failure to complete the proposed transactions on or before such date is the result of such party’s failure to perform or comply, in all material respects, with any of the covenants, agreements or conditions of the asset purchase agreements. If we are not able to complete the proposed transactions by the end date, even if we decide not to terminate the asset purchase agreements, we may not be able to prevent Quadvest from exercising its right to terminate the asset purchase agreements.

In addition, if the asset purchase agreements are terminated under certain circumstances related to regulatory approvals, H2O America may be required to pay to Quadvest a termination fee of $21 million.

Failure to obtain financing for the proposed transactions on favorable terms or at all could negatively impact the operating results and financial condition of H2O America.

H2O America may seek to raise capital to finance the proposed transactions, including through the issuance of debt or equity securities. There can be no assurance that such financing will be available on favorable terms, or at all. The incurrence of additional indebtedness could adversely affect H2O America’s financial condition, results of operations, or cash flows. Additionally, equity financings may result in dilution to our existing stockholders and debt financings may contain covenants that restrict the actions of H2O America and its subsidiaries. Furthermore, any downgrade in H2O America’s credit ratings by rating agencies may negatively impact the market value and liquidity of H2O America’s debt and equity securities.
