Important factors that could cause actual results to differ materially from those expressed or implied by these forward-looking statements include: our ability to manage unexpected changes in workers’ compensation and health insurance claims and costs, including by WSEs; our ability to mitigate the distinct business risks we face as a co-employer; the effects of volatility in the financial and economic environment on the businesses that make up our client base; our inability to realize or sustain the expected benefits from our business realignment initiatives, and any associated increases in costs as a result of these initiatives; loss of clients for reasons beyond our control and the short-term contracts we typically use with our clients; the impact of regional or industry-specific economic and health factors on our operations; the impact of failures or limitations in the business systems and centers we rely upon; changes in our insurance coverage or our relationships with key insurance carriers; our ability to improve our services and technology to satisfy client and regulatory expectations, including with respect to artificial intelligence; our ability to effectively integrate businesses we have acquired or may acquire in the future; our ability to effectively manage and improve our operational effectiveness and resiliency; our ability to price our services at rates that our clients continue to find attractive; our ability to attract and retain qualified personnel; the effects of increased competition and our ability to compete effectively; the impact on our business of cyber-attacks, breaches, disclosures and other data-related incidents; our ability to comply with evolving data privacy, artificial intelligence and security laws; our ability to manage changes in, uncertainty regarding, or adverse application of the complex laws and regulations that govern our business; changing laws and regulations governing health insurance and employee benefits; the incurrence of losses related to employee retention tax credit claims filed on behalf of our clients; our ability to keep pace with changes in technology or provide timely enhancements to our solutions and support, including with respect to artificial intelligence; risks associated with our international operations, including potential political or economic risks; our ability to operate a business subject to numerous complex laws; changing laws and regulations governing health insurance and other traditional employee benefits at the federal, state, and local levels; our ability to be recognized as an employer of worksite employees and for our benefits plans to satisfy all requirements under federal and state regulations; changes in the laws and regulations that govern what it means to be an employer, employee or independent contractor; the impact of new and changing laws regarding remote work; our ability to comply with the licensing requirements that govern our solutions; the failure of third-party service providers performing their functions; the failure to comply with anti-corruption laws and regulations, economic and trade sanctions, and similar laws; the outcome of existing and future legal and tax proceedings; fluctuation in our results of operations, stock price and maintenance of performance measures year over year due to factors outside of our control; our ability to comply with the restrictions of our indebtedness and meet our debt obligations; the need for additional capital or to restructure our existing debt; the continuation of our stock repurchase program; and the impact of concentrated ownership in our stock by Atairos and other large stockholders and the anti-takeover provisions in our charter documents and under Delaware law. Any of these factors could cause our actual results to differ materially from our anticipated results.

Further information on risks that could affect TriNet’s results is included in our filings with the SEC, including under the headings “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and elsewhere in our most recent Annual Report on Form 10-K and Quarterly Reports on Form 10-Q, which are available on our investor relations website at http://investor.trinet.com and on the SEC website at www.sec.gov.

FINANCIAL STATEMENTS

Non-GAAP Financial Measures

In addition to the selected financial measures presented in accordance with U.S. Generally Accepted Accounting Principles (GAAP), we monitor other non-GAAP financial measures that we use to manage our business, to make planning decisions, to allocate resources and to use as performance measures in our executive compensation plan. These key financial measures provide an additional view of our operational performance over the long term and provide information that we use to maintain and grow our business.

The presentation of these non-GAAP financial measures is used to enhance the understanding of certain aspects of our financial performance. It is not meant to be considered in isolation from, superior to, or as a substitute for the directly comparable financial measures prepared in accordance with GAAP.

Non-GAAP Measure Definition How We Use The Measure

Adjusted EBITDA

• Net income, excluding the effects of:

- income tax provision,

- stock based compensation expense

- interest expense, bank fees and other,

- depreciation,

- amortization of intangible assets,

- amortization of cloud computing arrangements,

- restructuring costs, and

- transaction and integration costs.

• Provides period-to-period comparisons on a consistent basis and an understanding as to how our management evaluates the effectiveness of our business strategies by excluding certain non-recurring costs, which include restructuring costs and transaction and integration costs, as well as certain non-cash charges such as depreciation and amortization, and stock-based compensation and certain impairment charges recognized based on the estimated fair values. We believe these charges are either not directly resulting from our core operations or not indicative of our ongoing operations.

• Enhances comparisons to the prior period and, accordingly, facilitates the development of future projections and earnings growth prospects.

• Provides a measure, among others, used in the determination of incentive compensation for management.

• We also sometimes refer to Adjusted EBITDA margin, which is the ratio of Adjusted EBITDA to total revenues.

Adjusted Net Income

• Net income, excluding the effects of:

- effective income tax rate (1),

- stock based compensation expense,

- amortization of intangible assets, net,

- non-cash interest expense,

- restructuring costs

- transaction and integration costs, and

- the income tax effect (at our effective tax rate (1) of these pre-tax adjustments.)

• Provides information to our stockholders and board of directors to understand how our management evaluates our business, to monitor and evaluate our operating results, and analyze profitability of our ongoing operations and trends on a consistent basis by excluding certain non-cash charges.

Free Cash Flow

• Net cash provided by operating activities reduced by capital expenditures • Provides information on the strength of our liquidity and available cash.

• Provides management with a measure to assist in making planning decisions, evaluate our performance and allocate resources.

• We also sometimes refer to Free Cash Flow Conversion ratio, which is the ratio of free cash flow to Adjusted EBITDA.

(1) Non-GAAP effective tax rate is 25.5% and 25% for second quarters and full years of 2026 and 2025, respectively, which excludes the income tax impact from stock-based compensation, changes in uncertain tax positions, and nonrecurring benefits or expenses from federal legislative changes.
