REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and the Board of Directors of TriNet Group, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of TriNet Group, Inc. and subsidiaries (the "Company") as of December 31, 2025 and 2024, the related consolidated statements of income and comprehensive income, stockholders’ equity, and cash flows, for each of the three years in the period ended December 31, 2025, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2025, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 12, 2026, expressed an unqualified opinion on the Company's internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the 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 audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that 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. We believe that our audits provide a reasonable basis for our opinion.

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.

Accrued Workers’ Compensation and Health Insurance Costs - Refer to Note 1 and Note 6 to the financial statements

Critical Audit Matter Description

The Company offers its clients and worksite employees (WSEs) workers' compensation insurance and health insurance coverage through insurance policies provided by third-party insurance carriers. The Company is obligated to reimburse the insurance carriers for losses up to defined deductible limits, in accordance with the insurance policies. Accrued workers’ compensation and health insurance costs are established to provide for the estimated unpaid costs of reimbursing the carriers.

The accrued workers’ compensation costs include estimates for reported and incurred but not reported losses, accrued costs on reported claims, and expenses associated with settling the claims. The estimates are based on the Company’s historical and industry loss experience, exposure data, an estimate of future cost trends, expected loss ratios, and loss development factors.

The accrued health insurance costs include estimates for claims incurred but not paid. The estimates are based on the Company’s historical claim payment patterns and medical cost trends, current period claim costs and claim reporting patterns, and plan enrollment.

Both the accrued workers’ compensation and health insurance costs are established using actuarial methods followed in the insurance industry and the Company uses qualified actuaries to develop these estimates.

Given the subjectivity of estimating the value of the accrued workers’ compensation and health insurance costs, performing audit procedures to evaluate whether accrued workers’ compensation and health insurance costs recorded for the year ended December 31, 2025 required a high degree of auditor judgment and an increased extent of effort, including the need to involve our actuarial specialists.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the accrued workers’ compensation and health insurance costs included the following, among others:

•We tested the effectiveness of controls related to accrued workers’ compensation and health insurance costs.

•We tested the underlying data that served as inputs into the actuarial analyses, including testing historical claims and enrollment data and recreating the claim loss triangles.

•With the assistance of our actuarial specialists, we evaluated the methods and key assumptions used by management to estimate the accrued workers’ compensation and health insurance costs:

◦Compared management’s prior-year assumptions of expected development and ultimate loss to actuals incurred during the current year to identify potential bias in the determination of the accrued workers’ compensation and health insurance costs.

◦Developed an independent range of estimates of the accrued costs, utilizing loss development factors and future cost trends for accrued workers’ compensation costs and claim payment patterns and medical trend rates for accrued health insurance costs. We compared our estimated ranges to management’s estimates.

Basis for Opinion

The Company’s management is responsible 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 Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the 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 audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

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.
