Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of SJW Group and subsidiaries (the “Company”) as of December 31, 2024 and 2023, the related consolidated statements of comprehensive income, changes in stockholders’ equity, and cash flows, for each of the three years in the period ended December 31, 2024, and the related notes and the schedules listed in the Index at Item 15 (collectively referred to as the “financial statements”). We also have audited the Company’s internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2024, in conformity with accounting principles generally accepted in the United States of America (“generally accepted accounting principles”). Also, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control – Integrated Framework (2013) issued by COSO.

Basis for Opinions

The Company’s management is responsible for the financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying “Management’s Report on Internal Control over Financial Reporting.” Our responsibility is to express an opinion on the financial statements and an opinion on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the financial statements included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures to respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Impact of Rate Regulation on the Financial Statements — Refer to Note 3 to the financial statements

Critical Audit Matter Description

The Company is subject to rate regulation by state utility regulatory agencies (the “Commissions”), which have jurisdiction with respect to the rates of the Company’s water and wastewater services. Management has determined it meets the requirements under generally accepted accounting principles to prepare its financial statements applying the specialized rules to account for the effects of cost-based rate regulation. Accounting for the economics of rate regulation impacts multiple financial statement line items and disclosures, such as depreciable utility plant; regulatory assets and liabilities; operating revenues; operation and maintenance expense; and depreciation expense.

The Commissions establish rates for the purpose of permitting the recovery of the cost of service and a return on investment. The Company’s rates are subject to regulatory ratemaking processes. The Company records deferred costs and credits on the consolidated balance sheets as regulatory assets and liabilities when it is probable that these costs and credits will be recognized in the ratemaking process in a period different from when the costs and credits are incurred. Accounting for such costs and credits is based on management’s judgment and prior historical ratemaking practices, and it occurs when management determines that it is probable that these costs and credits will be recognized in the future revenue of the Company through the ratemaking process.

We identified the impact of rate regulation as a critical audit matter due to the significant judgments that underlie the Company’s financial statement line items and disclosure impacted by rate regulation and the high degree of subjectivity involved in assessing the impact of regulatory decisions on the financial statements. Management judgments include assessing the probability of (1) recovery in future rates of incurred costs and (2) the requirement to refund amounts to customers. Given that management’s accounting judgements are based on consideration of evidence, such as regulatory rules and decisions, past practice, and the uncertain outcomes of future regulatory decisions, auditing these judgements required specialized knowledge of accounting for rate regulation and the rate setting process due to its inherent complexities and pervasive impact on the financial statements.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the impact of rate regulation include the following, among others:

•We tested the effectiveness of management’s controls over the initial recognition of amounts as utility plant and regulatory assets or liabilities and the evaluation of the probability of (1) the recovery in future rates of costs incurred as utility plant and deferred as regulatory assets, and (2) a refund or a future reduction in rates that should be reported as regulatory liabilities. We also tested the effectiveness of management’s controls over the monitoring and evaluation of regulatory developments that may affect the probability of recovering costs in future rates or of a future reduction in rates, and controls over relevant computations impacting certain regulatory asset or liability balances.

•We read regulatory orders issued by the Commissions to the Company, regulatory statutes, and other publicly available information to evaluate management’s determination of the accounting impacts of any new or revised regulatory decisions and their impact on measurement of related regulatory assets and liabilities.

•We obtained supporting documentation from management regarding the evidence, such as regulatory rules and decisions, past practices, and other facts and circumstances, used in the measurement of regulatory assets and liabilities for compliance with the related orders. We reconciled the underlying data or inputs used in the measurement to rate decisions approved by the Commissions and tested the mathematical accuracy of the calculations.

•We obtained an analysis from management regarding probability of recovery for regulatory assets or refund or future reduction in rates for regulatory liabilities not yet addressed in a regulatory order to assess management’s assertion that amounts are probable of recovery or a future reduction in rates.

•We evaluated the Company’s disclosures related to the impacts of rate regulation, including the balances recorded, and regulatory developments, were appropriate and consistent with the information obtained in our procedures.

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. 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 rainfall curtail water usage and sales.
