NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

NOTE 1. DESCRIPTION OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES

Description of Business

TriNet Group, Inc. (TriNet, or the Company, we, our and us) provides comprehensive HCM solutions for small and medium-size businesses under both a PEO model and an HRIS services model. These HCM solutions include multi-state payroll processing and tax administration, employee benefits programs, including health insurance and retirement plans, workers' compensation insurance and claims management, employment and benefit law compliance, and other HR-related services. Through our PEO service model, we are the employer of record for certain employment-related administrative and regulatory purposes for WSEs, including:

•compensation through wages and salaries,

•certain employer payroll-related tax payments,

•employee payroll-related tax withholdings and payments,

•employee benefit programs, including health and life insurance, and

•workers' compensation coverage.

Our PEO clients are responsible for the day-to-day job responsibilities of the WSEs.

Through our HRIS services model, we provide cloud-based HCM services to SMBs that allows them to manage hiring, onboarding, employee information, payroll processing, payroll tax administration, health insurance, and other benefits, from a single cloud-based software platform. We are not the co-employer or employer of record for such employees.

We operate inone reportable segment. All of our service revenues are generated from external clients. Less than 1% of our revenue is generated outside of the U.S.

Basis of Presentation and Basis of Consolidation

These unaudited condensed consolidated financial statements and accompanying notes have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial reporting and the instructions to Form 10-Q and Rule 10-01 of Regulation S-X of the Rules and Regulations of the Securities and Exchange Commission. The unaudited condensed consolidated financial statements include the accounts of the Company and an entity consolidated under the variable interest model. Intercompany balances and transactions have been eliminated. Certain information and note disclosures included in our annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. In the opinion of management, the condensed consolidated financial statements reflect all adjustments, that are normal and recurring in nature, necessary for fair financial statement presentation. The results of operations for the three and nine months ended September 30, 2024 are not necessarily indicative of the operating results anticipated for the full year. These financial statements should be read in conjunction with the audited Consolidated Financial Statements included in Part II, Item 8. Financial Statements and Supplementary Data of our Annual Report on Form 10-K for the year ended December 31, 2023. Certain prior year amounts have been reclassified to conform to current period presentation.

When entering into contractual arrangements with other entities, we assess whether we have a variable interest. If we determine that we have a variable interest, we then determine whether the arrangement is with a variable interest entity ("VIE"). If the arrangement is with a VIE, we assess whether we are the primary beneficiary of the VIE by identifying the most significant activities and determining who has the power over those activities and who has the obligation to absorb the majority of the losses or benefits of the VIE. We consolidate a VIE when we have the power to direct activities that most significantly affect the economic performance of the VIE and have the obligation to absorb the majority of their losses or benefits, making us the primary beneficiary.

Periodically, we assess whether any changes in our interest or relationship with the entity affect our determination of whether the entity is a VIE and, if so, whether we are the primary beneficiary.

In December 2023, we created a trust ("TriNet Trust") for the purpose of holding HRIS clients' payroll funds for the remittance to HRIS Users, tax authorities and other recipients. TriNet Trust's assets are restricted and can only be used for payments on behalf of HRIS clients, payments on behalf of the HRIS Users, repayments of any advances from TriNet, or payments to TriNet of interest income earned on the balances of TriNet Trust. In the event of any

losses, creditors to the Trust have recourse to TriNet Trust's property and not that of TriNet overall. The risks associated with the Trust are similar to those that currently exist for the Company such as banking losses in excess of FDIC insurance levels, interest rate and market conditions.

We determined that TriNet Trust meets the definition of a variable interest entity and as the primary beneficiary we have both the power to direct TriNet Trust’s activities that most significantly affect its performance and we have the right to receive benefits from TriNet Trust, in the form of interest income. As a result, TriNet Trust is consolidated into our financial statements. During the first quarter of 2024, TriNet Trust assumed ownership and responsibility of certain bank accounts that hold HRIS client funds and assumed related liabilities.

The following table presents the assets and liabilities of TriNet Trust which are included in our consolidated balance sheet. These amounts on any particular date can vary due to timing of cash receipts and remittances.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect certain reported amounts and related disclosures.

These estimates are based on historical experience and on various other assumptions that we believe to be reasonable from the facts available to us. Some of the assumptions are highly uncertain at the time of estimation. To the extent actual experience differs from the assumptions used, our condensed consolidated financial statements could be materially affected.

Revenue Recognition

Variable Consideration and Pricing Allocation

From time to time, we may offer credits to our clients considered to be variable consideration. Incentive credits related to contract renewals are recorded as a reduction to revenue as part of the transaction price at contract inception and are allocated among the performance obligations based on their relative standalone selling prices.

We allocate the total transaction price to each performance obligation based on the estimated relative standalone selling prices of the promised services underlying each performance obligation. The transaction price for the payroll and payroll tax processing performance obligations is determined upon establishment of the contract that contains the final terms of the arrangement, including the description and price of each service purchased. The estimated service fee is determined based on observable inputs and includes the following key assumptions: target profit margin, pricing strategies including the mix of services purchased and competitive factors, and client and industry specifics.

The fees for access to health benefits and workers' compensation insurance performance obligations are determined during client on-boarding and annually through the enrollment processes based on the types of benefits coverage the WSEs have elected and the applicable risk profile of the client. We estimate our service fees based on actuarial forecasts of our expected insurance premiums and loss sensitive premium costs and amounts to cover our costs to administer these programs.

We require our clients to prefund payroll and related taxes and other withholding liabilities before payroll is processed or due for payment. Under the provision of our contracts with clients, we generally will process the payment of a client’s payroll only when the client successfully funds the amount required. As a result, there is no financing arrangement for the contracts. However, certain contracts to provide payroll and payroll tax processing services permit the client to pay certain payroll tax components ratably over periods of up to 12 months rather than as payroll tax is otherwise determined and due, which may be considered a significant financing arrangement under FASB ASC Topic 606 Revenue from Contracts with Customers. However, as the period between our performing the service under the contract and when the client pays for the service is less than one year, we have elected, as a practical expedient, not to adjust the transaction price.

In previous years, we created our Recovery Credits to assist in the economic recovery of our existing PEO clients and enhance our ability to retain these clients. These credits were based on the performance of our insurance costs and were recorded as a reduction to insurance services revenues and included in client deposits and other client liabilities on the consolidated balance sheets. As of September 30, 2024, all Recovery Credits have been distributed to clients. The change in balance for the liability for credits previously accrued is the following:

Accrued Health Insurance Costs

We sponsor and administer a number of employee benefit plans for our PEO WSEs, including group health, dental, and vision as an employer plan sponsor under section 3(5) of the ERISA. In the nine months ended September 30, 2024, the majority of our group health insurance costs were related to risk-based plans. Our remaining group health insurance costs were for guaranteed-cost policies.

Accrued health insurance costs are established to provide for the estimated unpaid costs of reimbursing the carriers for paying claims within the deductible layer in accordance with risk-based health insurance policies. These accrued costs include estimates for claims incurred but not paid. We assess accrued health insurance costs regularly based upon actuarial studies that include other relevant factors such as current and historical claims payment patterns, plan enrollment and medical trend rates.

In certain carrier contracts we are required to prepay our obligations for the expected claims activity for subsequent periods. These prepaid balances by agreement permit net settlement of obligations and offset the accrued health insurance costs. As of September 30, 2024 and December 31, 2023, prepayments and miscellaneous receivables offsetting accrued health insurance costs were $56 million and $58 million, respectively. When the prepaid amount is in excess of our recorded liability the net asset position is included in prepaid expenses. As of September 30, 2024 and December 31, 2023, accrued health insurance costs offsetting prepaid expenses were $78 million and $68 million, respectively.

Restricted Cash, Cash Equivalents and Investments

Restricted cash, cash equivalents and investments presented on our consolidated balance sheets include:

•cash and cash equivalents in trust accounts functioning as security deposits for our insurance carriers,

•payroll funds collected representing cash collected in advance from clients which we designate as restricted for the purpose of funding WSE and HRIS User payroll and payroll taxes and other payroll related liabilities, and

•amounts held in trust for current and future premium and claim obligations with our insurance carriers, which amounts are held in trust according to the terms of the relevant insurance policies and by the local insurance regulations of the jurisdictions in which the policies are in force.

Recent Accounting Pronouncements

Recently issued accounting guidance

Income Taxes

In December 2023, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”), which will require the Company to disclose specified additional information in its income tax rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. ASU 2023-09 will also require the Company to disaggregate its income taxes paid disclosure by federal, state and foreign taxes, with further disaggregation required for significant individual jurisdictions. The ASU is effective for TriNet on a prospective basis for annual periods beginning after December 15, 2024. We are currently evaluating the provisions of this ASU.

Segment Reporting

In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”), which will require the Company to disclose segment expenses that are significant and regularly provided to the Company’s chief operating decision maker (“CODM”). In addition, ASU 2023-07 will require the Company to disclose the title and position of its CODM and how the CODM uses segment profit or loss information in assessing segment performance and deciding how to allocate resources. The ASU is effective for TriNet for annual periods beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. We are currently evaluating the provisions of this ASU.

NOTE 2. CASH, CASH EQUIVALENTS AND INVESTMENTS - UNRESTRICTED AND RESTRICTED

Under the terms of the agreements with certain of our workers' compensation and health benefit insurance carriers, we are required to maintain collateral in trust accounts for the benefit of specified insurance carriers and to reimburse the carriers’ claim payments within our deductible layer. We invest a portion of the collateral amounts in marketable securities. We report the current and noncurrent portions of these trust accounts as restricted cash, cash equivalents and investments on the consolidated balance sheets.

We require our clients to prefund their payroll and related taxes and other withholding liabilities before payroll is processed or due for payment. This prefund, for PEO customers, as well as amounts held by our statutory trust for our HRIS Users, is included in restricted cash, cash equivalents and investments as payroll funds collected, which is designated to pay pending payrolls, payroll tax liabilities and other payroll withholdings.

We also invest available corporate funds, primarily in fixed income securities which meet the requirements of our corporate investment policy and are classified as AFS.

Our total cash, cash equivalents and investments are summarized below:

NOTE 3. INVESTMENTS

The following tables summarize our financial instruments by significant categories and fair value measurement on a recurring basis as of September 30, 2024 and December 31, 2023 and the amortized cost, gross unrealized gains, gross unrealized losses, fair value of our AFS investments:

Fair Value of Financial Instruments

We use an independent pricing source to determine the fair value of our securities. The independent pricing source utilizes various pricing models for each asset class, including the market approach. The inputs and assumptions for the pricing models are market observable inputs including trades of comparable securities, dealer quotes, credit spreads, yield curves and other market-related data.

We have not adjusted the prices obtained from the independent pricing service and we believe the prices received from the independent pricing service are representative of the prices that would be received to sell the assets at the measurement date (exit price).

The carrying value of the Company's cash equivalents and restricted cash equivalents approximate their fair values due to their short-term maturities.

We did not have any Level 3 financial instruments recognized in our condensed consolidated balance sheets as of September 30, 2024 and December 31, 2023. There were no transfers between levels as of September 30, 2024 and December 31, 2023.

Sales and Maturities

The fair value of debt investments by contractual maturity are shown below:

The gross proceeds from sales and maturities of AFS securities for the three and nine months ended September 30, 2024 and 2023 are presented below. We hadimmaterial gross realized gains and losses from sales of investments for the three and nine months ended September 30, 2024 and 2023.

Fair Value of Long-Term Debt

The fair value of our 2029 Notes and 2031 Notes was obtained from a third-party pricing service and is based on observable market inputs. As such, the fair value of the Senior Notes is considered Level 2 in the hierarchy for fair value measurement. As of September 30, 2024, our 2029 Notes and 2031 Notes were carried at their cost, net of issuance costs, and had a fair value of $464 million and $417 million, respectively. As of December 31, 2023, our 2029 Notes and 2031 Notes were carried at their cost, net of issuance costs, and had a fair value of $443 million and $414 million, respectively.

Our 2021 Revolver is a floating rate debt. At September 30, 2024 and December 31, 2023, the fair value of our 2021 Revolver approximated its carrying value (exclusive of issuance costs). The fair value of our floating rate debt is estimated based on a discounted cash flow, which incorporates credit spreads, market interest rates and contractual maturities to estimate the fair value and is considered Level 3 in the hierarchy for fair value measurement.

NOTE 4. ACCRUED WORKERS' COMPENSATION COSTS

The following table summarizes the accrued workers’ compensation cost activity for the three and nine months ended September 30, 2024 and 2023:

The following summarizes workers' compensation liabilities on the condensed consolidated balance sheets:

Incurred claims related to prior years represent changes in estimates for ultimate losses on workers' compensation claims. For the three months ended September 30, 2024, incurred losses from prior years increased primarily due to a relatively higher than expected reported claim frequency and severity for 2023 claims in comparison to 2024 claims. For the nine months ended September 30, 2024, favorable development is due to lower than expected reported claim frequency and severity for years prior to 2023.

As of September 30, 2024 and December 31, 2023, we had $26 million and $32 million of collateral held by insurance carriers of which $4 million and $5 million, respectively, was offset against accrued workers' compensation costs as the agreements permit and are net settled of insurance obligations against collateral held.

NOTE 5. COMMITMENTS AND CONTINGENCIES

Contingencies

We are and, from time to time, have been and may in the future become involved in various litigation matters, legal proceedings, and claims arising in the ordinary course of our business, including disputes with our clients or various class action, collective action, representative action, and other proceedings arising from the nature of our co-employment relationship with our clients and WSEs in which we are named as a defendant. In addition, due to the nature of our co-employment relationship with our clients and WSEs, we could be subject to liability for federal and state law violations, even if we do not participate in such violations. While our agreements with our clients contain indemnification provisions related to the conduct of our clients, we may not be able to avail ourselves of such provisions in every instance. We have accrued our current best estimates of probable losses with respect to these matters, which are individually and in aggregate immaterial to our consolidated financial statements.

While the outcome of the matters described above cannot be predicted with certainty, management currently does not believe that any such claims or proceedings will have a materially adverse effect on our consolidated financial position, results of operations, or cash flows. However, the unfavorable resolution of any particular matter or our

reassessment of our exposure for any of the above matters based on additional information obtained in the future could have a material impact on our consolidated financial position, results of operations, or cash flows.

NOTE 6. STOCK BASED COMPENSATION

Restricted Stock Units (RSUs)

Time-based RSUs generally vest over afour-year term. Performance-based RSUs are subject to vesting requirements and are earned, in part, based on certain financial performance metrics as defined in the grant notice. Actual number of shares earned may range from 0% to 200% of the target award. Performance-based awards granted in 2024 and 2023 are earned based on a single-year performance period subject to subsequent multi-year time-based vesting with 50% of the shares earned vesting inone year after the performance period and the remaining shares in the year after. RSUs are generally forfeited if the participant terminates service prior to vesting.

The following tables summarize RSU activity for the nine months ended September 30, 2024:

Time-based RSUs

Performance-based RSUs

Stock Based Compensation

Stock based compensation expense for stock-based awards made to our employees pursuant to our equity plans were as follows:

NOTE 7. STOCKHOLDERS’ EQUITY

Common Stock

The following table shows the beginning and ending balances of our issued and outstanding common stock for the three and nine months ended September 30, 2024 and 2023:

Stock Repurchases

As of September 30, 2024, there was $279 million remaining in the total authorization of $2,715 million of our ongoing stock repurchase program.

Dividends

In February 2024, our board of directors authorized a dividend of $0.25 per share for an aggregate amount of approximately $13 million, which was paid in April 2024. In June 2024, our board of directors authorized a dividend of $0.25 per share for an aggregate amount of approximately $12 million, which was paid in July 2024. In September 2024, our board of directors authorized a dividend of $0.25 per share for an aggregate amount of approximately $12 million, to be paid in October 2024.

NOTE 8. INCOME TAXES

Our ETR was 23% and 24% for the third quarter of 2024 and 2023, respectively, and 25% and 26% for the nine months ended September 30, 2024 and 2023, respectively. The decrease in rates as compared to the same periods in 2023 was primarily due to an increase in excludable income for state tax purposes and adjustments to prior year tax expense.

We are subject to tax in U.S. federal and various state and local jurisdictions, as well as Canada and India. We are open to federal and significant state income tax examinations for tax years 2019 and subsequent years.

NOTE 9. EARNINGS PER SHARE

Basic EPS is computed based on the weighted average shares of common stock outstanding during the period. Diluted EPS is computed based on those shares used in the basic EPS computation, plus potentially dilutive shares issuable under our equity-based compensation plans using the treasury stock method. Shares that are potentially anti-dilutive are excluded.

The following table presents the computation of our basic and diluted EPS attributable to our common stock:
