PART I

Item 1. Business

TriNet is a leading provider of HR solutions for SMBs. We offer technology-enabled services that include human capital expertise, employee benefits such as health insurance and retirement plans, payroll and payroll tax administration, risk mitigation, and compliance consulting. Our long-term objective is to be the premier provider of HR services for a broad range of SMBs through industry-leading benefits, sales distribution excellence, and a world-class services delivery model.

Since our founding in 1988, TriNet has served, and continues to serve, thousands of SMBs. We are the largest publicly traded company in the U.S. that focuses primarily on the PEO business, in terms of market capitalization as of December 31, 2025. In 2025, we processed $70 billion in payroll and payroll taxes for our clients and ended the year with approximately 323,200 WSEs.

We aim to differentiate ourselves from other PEOs in three substantive areas. First, we offer a high-quality, technology-enabled service solution that is tailored to employee-centric SMBs. Our primary targeted industry verticals include technology, financial services, life sciences, nonprofit, professional services, and main street. Second, we offer our clients a premium HR advisory experience featuring high-touch services and efficient issue resolution, to yield a high level of customer satisfaction and retention. Finally, we believe our risk-based model allows our clients to better manage their benefits costs over the long term.

Our medium-term strategy includes taking actions to increase revenue growth through improved benefits options and risk management capabilities, expanded sales force scale, tenure, and productivity, as well as expanded distribution channels. We continue to focus on improving our client and WSE experience to raise our net promoter scores and increase retention. In addition, we are focusing on cost discipline, operational efficiencies in our service delivery model, and prudent capital allocation, while being strategic with investments.

In late 2024, we began undertaking certain transformation initiatives to support our goals of being "best in benefits, best in platform, best in service." These initiatives are designed to evolve the technology and processes we use to support our sales and marketing efforts and our core customer-facing operational activities, enhance our customer support model, provide industry-leading best in benefits offerings and strengthen our talent and culture, while supporting our revenue growth, margin improvement and productivity. We have increased and are continuing to increase our use of technological solutions and AI in how we operate our business, including our up-front client consulting services, our sales and retention practices, and lead generation, which we believe has led and will continue to lead to stronger customer engagement measured through our net promoter score.

In 2025, we expanded our ASO service offering to include HR Plus which is a SaaS solution combined with our distinctive high-level of service. We believe our success with our ASO service has been enabled by our deep knowledge of and expertise with HR and the challenges faced by SMBs. In addition, in 2025 we announced plans to launch TriNet Assistant, which we expect to be a suite of human-centered, AI-powered capabilities designed to deliver intelligent and responsive HR support with privacy and security controls for our clients, which we expect to launch in 2026.

Our Service Models

We deliver a comprehensive suite of services that help our clients administer and manage various HR-related needs and functions, such as compensation, benefits, payroll processing, tax credit support, employee data, health insurance, workers' compensation, EPLI and other employment risk mitigation programs, employee performance management and training, on-boarding and off-boarding, and other transactional HR needs using our PEO technology platform and benefits and compliance expertise.

We deliver our services primarily through our PEO services that we provide via our co-employment model and through our ASO services, which provide payroll processing, HR administration and compliance management solutions.

PEO Services

TriNet has historically focused almost exclusively on the PEO business, and PEO services remain our core business. Our PEO services offer our clients our most complete HCM solution within the co-employment model and generally include all of the services described below.

ASO Services

Our ASO services, which includes our “HR Plus” product, consist of a SaaS solution with a significant service

component. ASO services include payroll processing, benefits management, HR administration and compliance management to provide HCM solutions that our clients can tailor dynamically over time based on their specific needs. Unlike our PEO services, ASO services do not include co-employment or access to our TriNet sponsored health benefit plans. However, our ASO clients have access to our benefits administration platform that can administer third-party benefits and integrates with 401(k) retirement plans.

The transition from our prior HRIS offering to our ASO offering in 2025 resulted in increased attrition from our prior HRIS population, as our ASO offering provided a significant increase in the level of services offered alongside a price increase. These losses were partially offset by an increase in clients for our ASO services. As of December 31, 2025, we had approximately 39,700 ASO Users and approximately 18,600 legacy HRIS Users.

Our Services

Our comprehensive HR solutions include the following capabilities:

HR CONSULTING EXPERTISE

BENEFIT
OPTIONS

PAYROLL SERVICES

RISK MITIGATION

TECHNOLOGY
PLATFORM

CONTRACTOR AND GLOBAL WORKFORCE SUPPORT

HR Consulting Expertise

We use the collective knowledge and experience of our teams of HR, benefits, payroll, risk management and compliance professionals to help our clients navigate many of the administrative, regulatory and practical requirements associated with being employers. We do this by incorporating our knowledge and experience into our services and our technology platforms and by making our professionals available to consult with clients on a variety of HR needs, including talent management, retention and terminations, benefits enrollment, immigration and visas, payroll tax credits, employment compliance and regulatory developments and many other industry-specific and general HR topics. Depending on their needs, our clients have access to varying levels of service and support from our professionals, ranging from call center support to pooled HR resources. Our professionals also provide additional specialized HR consulting services upon request.

Benefit Options

In our PEO business, we utilize our scale to provide our WSEs access to a broad range of TriNet-sponsored employee benefit and insurance programs with features and at costs that we believe many of our clients would be unable to obtain on their own. We believe that our TriNet-sponsored programs help our PEO clients compete for talent against larger businesses. Our benefit and insurance programs are designed to comply with federal, state and local regulations, and our benefit and insurance service offerings include plan selection and administration, enrollment management, leave management, plan document distribution and WSE and client communications.

Under these benefit and insurance programs, we pay third-party insurance carriers for WSE insurance benefits and reimburse insurance carriers or third-party administrators for claims payments within our insurance deductible layer, where applicable.

We sponsor and administer several employee benefit plans for our WSEs through a broad range of carriers, including group health, dental, vision, short- and long-term disability, and life insurance as an employer plan sponsor under Section 3(5) of ERISA. We also sponsor or otherwise provide WSEs access to other benefit programs, including flexible spending accounts, health savings accounts, retirement benefits, COBRA benefits, supplemental insurance, and commuter benefits. We also facilitate payroll deductions for WSEs to voluntarily purchase home insurance, critical illness insurance, accident insurance, hospital indemnity, pet insurance, and auto insurance.

We also offer PEO clients the option to obtain their own client-sponsored benefits through our OMS product family. Our OMS clients receive PEO services such as HR, payroll, payroll tax, and risk management from us while sponsoring their own health benefits obtained through a broker.



TRINET	6	2025 FORM 10-K


BUSINESS			Table of Contents

Payroll Services

We help our PEO and ASO clients manage their employee compensation by providing multi-state payroll processing, tax administration and tax credit services and other payroll-related services, such as time and attendance management, time off and overtime tracking, and expense management solutions. Our clients and WSEs can access payroll and tax information using our various online and mobile tools. Our payroll tax administration and tax credit services include calculating, withholding, remitting and reporting certain federal, state and local payroll and unemployment taxes on behalf of clients and WSEs.

Risk Mitigation

We monitor employment-related legal and regulatory developments at the federal, state, and local levels to help our PEO and ASO clients comply with employment laws and mitigate many of the risks associated with being an employer. We provide HR guidance on employment laws and regulations, such as those relating to minimum wage, unemployment insurance, family and medical leave and anti-discrimination. For our PEO clients, our TriNet-sponsored benefit plans are designed to comply with applicable laws and regulations, such as the ACA, reducing this compliance burden for our clients.

Our PEO services provide fully-insured workers' compensation insurance coverage for our clients and WSEs through insurance policies that we negotiate with third-party insurance carriers. We manage the deductible risk that we assume in connection with these policies by being selective in the types of businesses that we take on as new clients, and by monitoring claims data and performance of our carriers and third-party claims management service providers. In addition, we advise clients on workers’ compensation best practices, including by performing workplace assessment consultations and assisting with client efforts to identify conditions or practices that might lead to employee injuries.

We also provide EPLI coverage for our PEO clients through an insurance policy that we obtain from a third-party EPLI carrier. This policy provides coverage for certain claims that arise in the course of the employment relationship, such as discrimination, harassment, and certain other employee claims, with a per-claim retention amount. The retention amount under this policy, which functions like a deductible, is allocated on a pre-determined basis between the client and TriNet. Our professionals assist our clients in implementing HR best practices to help avoid and reduce the cost of employment-related liabilities. Our preferred outside employment law firms defend covered EPLI claims.

Technology Platform

Our technology platform includes online and mobile tools that allow our clients and WSEs to store, view, and manage HR information and administer a variety of HR transactions, such as payroll processing, tax administration, tax credits, employee onboarding and termination, employee performance, time and attendance, compensation reporting, expense management, and benefits enrollment and administration. Our online tools also incorporate workforce analytics, allowing PEO and ASO clients to generate HR, payroll, total compensation and other custom reports.

Contractor and Global Workforce Support

TriNet provides clients with a simplified solution for handling independent contractors with our contractor payments application, featuring a software solution that allows clients to onboard, manage and pay independent contractors. In addition, for clients with employees outside the U.S., we provide payroll and HR support through international employer of record partners.

Our PEO Co-Employment Model

Our PEO services operate on the basis of a co-employment model, under which employment-related responsibilities are allocated by contract between us and our PEO clients. The co-employment model allows WSEs to receive the full scope of our services, including providing WSEs with access to TriNet-sponsored employee benefit plan offerings. Each of our PEO clients enters into a client service agreement with us that defines the suite of services and benefits to be provided by us, the fees payable to us, and the division of responsibilities between us and our clients as co-employers. WSEs also separately acknowledge the co-employment relationship and the allocation of employment-related responsibilities between TriNet and the client co-employer. The division of responsibilities under our client service agreements is typically as follows:



TRINET	7	2025 FORM 10-K


BUSINESS			Table of Contents

TriNet Responsibilities

We generally assume responsibility for, and manage certain risks associated with:

•payments of salaries, wages and certain other compensation to WSEs from our own bank accounts (based on client reports and payments), including the processing of garnishment and wage deduction orders,

•reporting of wages, withholding and deposit of associated payroll taxes as the employer of record,

•provision and maintenance of workers' compensation insurance and workers' compensation claims processing,

•access to, and administration of, group health, welfare, and retirement benefits to WSEs under TriNet-sponsored benefit plans,

•compliance with applicable law for certain TriNet-sponsored employee benefits offered to WSEs,

•administration of unemployment claims and post-employment COBRA benefits, and

•provision of various HR policies and agreements, including employee handbooks and worksite employee agreements describing the co-employment relationship.

Client Responsibilities

Our clients are responsible for employment-related responsibilities that we do not specifically assume, generally including:

•day-to-day management of their worksites and WSEs,

•compliance with laws associated with the classification of employees as exempt or non-exempt, such as overtime pay and minimum wage law compliance,

•accurate and timely reporting to TriNet of compensation and deduction information, including information relating to hours worked, rates of pay, salaries, wages and other compensation, and work locations,

•accurate and timely reporting to TriNet of information relating to workplace injuries, employee hires and termination, and certain other information relevant to TriNet’s services,

•provision and administration of any employee benefits not provided by TriNet, such as equity incentive plans or nonqualified deferred compensation plans,

•compliance with all laws and regulations applicable to the clients' workplace and business, including work eligibility laws, laws relating to workplace safety or the environment, laws relating to family and medical leave, laws pertaining to employee organizing efforts and collective bargaining and employee termination notice requirements,

•payment of TriNet invoices, which include reimbursement for salary, wages and other relevant compensation to WSEs and applicable employment taxes and service fees, and

•all other matters for which TriNet does not assume responsibility under the client service agreement, such as intellectual property ownership and protection and liability for products produced and services provided by the client company to its own clients.

As a result of co-employment relationships for PEO services, we are liable for payment of salary, wages and certain other compensation to the WSEs as reported and paid to us by our client, and we are responsible for providing specified employee benefits to such persons to the extent provided in each client service agreement and under federal and state law. In most instances, clients are required to remit payment prior to the applicable payroll date by wire transfer or ACH.

For our PEO services, we also assume responsibility for payment and liability for the withholding and remittance of federal and state income and employment taxes with respect to salaries, wages and certain other compensation paid to WSEs, although we reserve the right to seek recourse against our clients for any liabilities arising out of their conduct. We perform these functions as the statutory employer for federal employment tax purposes since our clients transfer legal control over these payroll functions to us. The laws that govern the payment of salaries, wages and related payroll taxes for our WSEs are complex and the various federal, state and local laws that govern such payments can vary significantly. Based on applicable law in any jurisdiction, we or our client may be held ultimately liable for those obligations if we fail to remit taxes.



TRINET	8	2025 FORM 10-K


BUSINESS			Table of Contents

Our ASO Model

For clients that seek a less comprehensive set of services not involving co-employment, we offer ASO services that reduce the responsibility and liability that we assume when providing such services. For example, while we may facilitate payroll processing for ASO clients, TriNet is not the employer of record. ASO clients generally remain responsible for, among other things, workers’ compensation insurance, obtaining and sponsoring group health, welfare and retirement benefits, administering unemployment claims, and in some cases payroll tax reporting. The additional responsibilities that PEOs assume, and the risks that PEOs manage, for our PEO clients are key differences between our PEO and ASO services. We believe that ASO services represent a substantial share of the market for outsourced HR services.

Our Technology and Service Development Efforts

We continued to make significant investments in our technology platform. These investments are intended to provide our clients (both PEO and ASO clients) and WSEs with enhanced functionality, ease of use, HR management options, security and an optimized user experience. We intend to continue making these and other similar investments in 2026 and beyond, aiming to drive operating efficiencies and improve client retention and satisfaction over the long term.

In 2025, we continued to develop our next-generation cloud-based platform. This new platform, which combines elements of our original PEO and ASO platforms, is intended to further modernize our customers’ experience through more self-service capabilities and other important functions to, in turn, enable us to service SMBs throughout a larger portion of their lifecycle. Moreover, we have also begun to explore integrating new technologies, including expanding our AI/ML capabilities to include services such as TriNet Assistant, which we expect to launch in 2026, into the customer experience to allow us to create efficiencies in the way we serve our customers and the way we operate internally.

Our Clients and Their Geographies

Our clients are distributed across a variety of industries. Our PEO clients generally execute annual service contracts with us that automatically renew. In most cases, our PEO clients may cancel these contracts with 30 days' notice to us and we may cancel these contracts with 30 days' notice to our clients. Our ASO clients execute contracts with monthly or annual terms and clients can typically cancel these contracts with 30 days’ notice to us. Clients on annual contracts may incur fees associated with early termination if notice of such terminations occur inside of the 30 day notice period prior to their contract’s anniversary date.

Our top five PEO markets are California, New York, Florida, Texas and Massachusetts, which account for approximately 64% of our total WSE paid wages for the year ended December 31, 2025. Nearly all of our revenues are generated within the United States and its territories and substantially all our long-lived assets are located in the United States.

Our Sales and Marketing Organizations

We market and sell our HCM solutions through a combination of direct sales and strategic partnerships. Our sales organization is structured by industry vertical, which allows us to focus on the distinct needs of SMBs within targeted sectors and to drive more efficient customer acquisition.

In addition to our direct sales force, we generate new business through relationships with brokers and other channel partners, which continue to be a meaningful source of referrals. Our marketing activities support these channels by building brand awareness, generating leads, and providing tools and content that facilitate the customer evaluation and onboarding process.

We utilize a mix of digital and traditional marketing methods to reach prospective clients, including online advertising, website engagement, and participation in industry and small‑business‑focused events. Our brand and communications functions also support customer engagement and retention through regular updates, educational resources, and other client‑facing communications.

With SMB behavior evolving rapidly, we have adopted digital tools such as telepresence, chat, and interactive assessments to enable us to engage SMBs in innovative ways. In 2025, we enhanced our digital engagement with tools such as conversational marketing on our website and interactive self-assessments.

Together, these coordinated sales and marketing efforts support our strategy to expand our presence in key industries, strengthen broker and partner relationships, and reinforce our positioning as a trusted HR solutions provider for SMBs.

Our Competitors

We face competition from:

•PEOs that compete directly with us,

•payroll processing agents and other HCM services providers that do not use a PEO model,

•HR and personnel of companies that administer employee benefits, payroll and HR for their companies in-house,

•providers of certain endpoint HR services, including payroll, employee benefits, business process outsourcers with high-volume transaction and administrative capabilities, and other third-party administrators, and

•insurance brokers who allow third-party HR systems to integrate with their technology platform.

PEO services remain our core business and other PEOs continue to represent our most significant competition. Our PEO service competitors include large PEOs such as the TotalSource unit of Automatic Data Processing, Inc., the PEO operations of Paychex, Inc. and Insperity, Inc., as well as numerous specialized and smaller PEOs and similar HR service providers with PEO operations.

We believe that a key reason why our PEO services are attractive to SMBs is because of our ability to provide access to a broad range of workers' compensation, health insurance and other benefits programs on a cost-effective basis. Our customers may obtain their own insurance through brokers and other providers of insurance and benefits coverage, and our PEO offerings must be priced competitively with those provided by these competitors for us to attract and retain our clients.

Our PEO clients are typically looking for high-touch HR compliance and services support, TriNet sponsored employee benefits, TriNet responsibility for processing payroll and payroll taxes, and access to EPLI claims support and other substantial HR services. By contrast, many of our ASO clients are looking for more self-directed, focused and less expensive ASO services. We do not co-employ the employees of our ASO clients and do not provide them with TriNet sponsored health benefits. As a result, our ASO services compete with services provided by a wider array of HCM companies outside of the PEO industry.

For additional information about our competition, please refer to Part I, Item 1A. Risk Factors, of this Form 10-K, under the heading – "We must continue to work to improve our services to meet the expectations of our clients and regulators, or we may lose our clients and materially harm our business".

Market Trends and Developments Affecting Our Business

The U.S. economy grew modestly during 2025 with unemployment remaining steady while inflation stabilized during the year. We observed the following industry trends in 2025:

•SMB Economic Performance. Over any year, SMBs generally experience staffing changes, either resulting in a net increase or decrease in staffing. The extent of net staffing changes can differ based on industry and geographic region. In 2025, our clients experienced modest staffing reductions across all of our verticals. Overall in 2025, net hiring was low relative to our historical experience.

•Continued Insurance Cost Variability and Volatility. We continued to experience higher than anticipated health benefits utilization and inflation in healthcare costs, which are affected by factors such as market-wide pharmaceutical price increases, as well as the impact of rising wages and other costs within the healthcare industry which led to increased costs associated with contract renewals between health insurers and health care providers.

•Tax Credit Backlogs. Many of the key economic assistance programs that SMBs relied on during the COVID-19 pandemic have now expired, including the ERTC. Although these programs have expired, processing backlogs and a temporary halt in September 2023 in processing new ERTC claims at the IRS have resulted in many SMBs, including some of our clients, continuing to wait to receive their tax credits. In many cases, SMBs still participated in these programs retroactively via payroll tax filing amendments. While the IRS processed a substantial number of claims in 2025, many SMBs continue to wait for their credits to be processed.

•Interest Rates. Short-term interest rates continued to fall from highs seen in 2024. While prior periods of higher interest rates may have resulted in lower overall hiring among our SMB clients, we have not yet seen hiring rates rise as a result of the recent decrease in short-term rates. Further, the lower short-term interest rates resulted in reduced interest income on our cash deposits, a driver of our financial results, but will also result in lower interest expense on any future outstanding borrowings under our 2021 Revolver.

•Privacy Laws and Regulations. We continue to see increased focus at every level of government inside and outside of the United States on regulating the collection, storage, use, retention, security, disclosure, transfer and other processing of confidential, sensitive and personal information, as well as the growing use of AI. As the patchwork of laws becomes increasingly complex, we expect the effort and cost of complying with all of the requirements to also increase and the likelihood of compliance failures to rise.

•PEO Benefit Plan Legislation. Various state governments from time to time seek to regulate PEO health plans. State regulations on PEO health plans can limit our options for providing TriNet sponsored benefits to our PEO clients or eliminate those benefits entirely. We devote substantial time and resources to monitor and respond to these developments. We expect to continue to see these legislative and regulatory efforts across the country.

For more information regarding the developments above, refer to Part II, Item 7. MD&A and Part I, Item 1A. Risk Factors in this Form 10-K.

The Laws and Regulations that Affect Our Business

Our business operates in a complex legal and regulatory environment due to myriad federal, state and local laws and regulations that impact our business. Below is a summary of what we believe are the most important legal and regulatory issues specific to our business. For additional information on the impact of these and other laws and regulations on our business and results of operations, refer to Part I, Item 1A. Risk Factors, of this Form 10-K, under the heading - "Legal and Compliance Risks".

Employer Status under ERISA and State Laws

As part of our PEO services, we sponsor employee benefit plans for the benefit of our WSEs. We believe we manage our employee benefit plans in accordance with ERISA and the Code requirements and that we are the employer of our WSEs with respect to the plans for purposes of the Code, ERISA and applicable state laws, but this status could be subject to challenge by various regulators. We believe that our benefit plans are exempt from many state regulations under ERISA, but our position could be challenged by state regulators or as a result of new laws, regulations, agency guidance, audits or case law at the federal and state levels.

Health Insurance and Health Care Reform

Our sponsored employee health and welfare offerings are an important component of the services that we provide. The future of health care reform continues to evolve in the U.S. Significant changes to health care statutes, regulations and policy at the federal, state and local levels could occur in the future, and we may need to adapt the manner in which we conduct our business as a result of any such changes.

Data Privacy and Security Regulations

We collect, store, use, retain, disclose, transfer and otherwise process a significant amount of confidential, sensitive and personal information from and about our actual and potential clients, WSEs, employees of ASO clients, and colleagues, and we are subject to a variety of federal, state and international laws, rules, and regulations in connection with such activities. As a sponsor of employee benefit plans, we also have access to certain protected health information (PHI) of our WSEs and colleagues. Management of PHI is subject to several regulations at the federal level, including HIPAA and the HITECH Act. HIPAA contains restrictions and health data privacy, security and breach notification requirements with respect to the use and disclosure of PHI. Further, there are penalties and fines for HIPAA violations. Because TriNet sponsored health plans are covered entities under HIPAA, our sponsored health plans are required to comply with HIPAA's portability, privacy, and security requirements. We are also subject, among other applicable federal laws, rules and regulations, to the rules and regulations promulgated under the authority of the Federal Trade Commission. In recent years, the federal government has increased its focus on and regulation of data privacy and security, and we expect this to evolve in the coming years.

At the state and local level, there is ongoing focus on regulating the collection, storage, use, retention, security, disclosure, transfer and other processing of confidential, sensitive and personal information. In recent years, many states have proposed or enacted new laws or amended existing laws and we expect them to continue to do so in the future. As state privacy laws become increasingly complex, we expect the cost and effort of complying with all of the requirements to increase and the likelihood of compliance failures to rise. Moreover, without the enactment of a comprehensive federal privacy law, we are required to comply with a patchwork of state laws that lacks uniformity which creates significant legal complexities for companies like TriNet that operate nationwide. Similarly, as we continue to expand our operations and services, we may be required to comply with similarly complex privacy security laws in the countries or regions in which we operate or provide services. Complying with existing and new privacy and security regulations could cause us to incur substantial costs or require us to change our business practices in a manner adverse to our business.

BUSINESS			Table of Contents

Licensing Laws

Nearly all states have adopted laws and regulations for licensing, registration, certification or recognition of PEOs and the IRS has implemented a voluntary federal certification program for PEOs. We expect states without such laws and regulations to adopt them in the future. While these laws and regulations can vary widely, most regulators monitor the financial health and other relevant business information of PEOs on an annual or quarterly basis. In some cases, these laws and regulations codify and clarify the co-employment relationship for certain payroll, unemployment, workers' compensation and other employment-related purposes or require specific client contractual terms and/or WSE disclosures. We believe we comply in all material respects with the applicable PEO laws and regulations in each state and jurisdiction in which we provide PEO services.

Every state regulates insurance practices conducted within their jurisdiction. While we do not broker insurance currently, certain of our PEO and ASO services involve assisting our clients in obtaining and managing employee benefits. We partner with brokers to provide these services and have elected to obtain state insurance licenses as a result. As each state’s licensing requirements differ, maintaining current licenses is complex and we are subject to insurance audits, investigations and fines if we fail to comply with insurance license requirements.

Other state regulatory authorities impose licensing requirements on companies involved in the transmission of cash, such as banks, and other money transmitters. We do not believe that our current activities require any such licenses, but we and others in our industry have received inquiries from regulatory authorities in the past and could receive them in the future.

Payroll Taxes, Unemployment Taxes and Payroll Tax Credits

We must also comply with the federal and state payroll tax and unemployment tax requirements that apply where our clients are located. Tax reform efforts, and other payroll tax changes, at the federal, state and local level can impact our payroll tax reporting obligations for our clients and the services we can provide. State unemployment tax rates vary by state based in part on prior years’ total wages, unemployment taxes paid and unemployment claims experience and may also vary based on the overall claims experience of a PEO in states in which we are required to report and pay unemployment taxes using one of our accounts and rates. As a result, depending on where client WSEs perform services for our clients, the fees we charge PEO clients for unemployment taxes can be higher or lower than a client could obtain without use of a PEO. In some cases, taxing authorities can retroactively increase the unemployment taxes we pay to cover deficiencies in the unemployment tax funds. We also rely on our clients to accurately inform us of the work and residence locations for their WSEs and ASO client employees, and inaccurate information, whether due to remote work policies or otherwise, can impact our payroll tax obligations and the obligations of our clients, WSEs and ASO client employees.

We have seen a growing trend, particularly at the federal level, of using payroll tax credits, deferrals and other related payroll tax programs as a mechanism for incentivizing SMB development and economic recovery. These programs are popular because they allow SMBs, which often have business income tax losses, to realize benefits via payroll tax reductions, rather than business income tax reductions. As a result, many of our SMB clients require that we support these programs. An example of these programs is the federal 2015 PATH Act. The PATH Act allows SMBs to use R&D tax credits submitted on the SMB’s business income tax return to reduce certain payroll taxes.

We act as the employer of record for federal payroll tax reporting for our PEO clients. This means that we file client tax credit claims and pass the associated tax credit refunds to our clients based on information supplied by our clients, which we do not control. These programs have generally not been designed with the PEO industry in mind and these programs are subject to broad agency interpretations given their complexity. While our clients are contractually responsible to us for their errors in tax credit submissions and for repaying us for all rejected tax credits under our service contracts, taxing authorities may still look to TriNet for repayment and we may not be able to effectively enforce or collect on these obligations.

Other Employment Regulations

We must also comply with labor and employment laws, which change frequently at the federal, state and local level. In particular for our PEO services, regulatory focus on the classification of employers, employees and independent contractors has the potential to significantly change how we and other PEOs operate and the services that we and other PEOs can provide to our clients and WSEs. States continue to consider, or have adopted, changing regulations or guidance around the definition of employers, employees and independent contractors and any change in these definitions may impact our ability to provide certain PEO and ASO services to certain employers or employees.

We must also comply with state and federal rules and guidelines around both independent contractor and joint employer status. Standards for determining independent contractor and joint employer status vary from law to law



TRINET	12	2025 FORM 10-K


BUSINESS			Table of Contents

and state to state, and changes to and new interpretations of these standards can limit the client workers to which we can provide services and increase the likelihood of claims that we are a joint employer of client WSEs or an employer of ASO client employees. We do not believe that we are a joint employer under any law or rule, or that past or proposed rule changes impact our status as a co-employer. However, laws regarding independent contractor and joint employer status can impact the types of SMB workers we can service and the potential liability that we have for the actions of our SMB clients and their employees.

Our Human Capital Resources

As of December 31, 2025, we had approximately 3,400 colleagues globally supporting approximately 323,200 WSEs and 39,700 ASO Users.

Our human capital strategy focuses on attracting, developing, and retaining the colleagues necessary to support our clients and execute our business objectives. As of December 31, 2025, none of our colleagues were covered by a collective bargaining agreement.

Talent Attraction and Retention

We seek to attract and retain qualified colleagues through competitive compensation and benefits, including comprehensive health coverage and a 401(k) plan with an immediately vested employer match. Our pay‑for‑performance program includes cash and equity‑based incentives tied to company and individual performance. We also offer an employee stock purchase plan that allows colleagues to acquire our stock at a discount.

Training and Development

We invest in colleague development through training programs, continuing education and tuition reimbursement, and leadership and functional skill‑building opportunities. We also offer specialized development programs designed to support career advancement in key roles.

Engagement and Culture

We regularly conduct colleague surveys to assess engagement, career development opportunities, and satisfaction with compensation and benefits. Senior leadership reviews the results and prioritizes actions in response to identified trends.

We also support colleague‑led resource groups that are open to all, and corporate social responsibility initiatives, including volunteer and philanthropic activities in the U.S. and India to support creating and maintaining an environment in which each employee can excel.

Workplace Flexibility and Locations

We provide flexible work arrangements, including remote, hybrid, and on‑site roles. Our primary on‑site centers are located in Hyderabad, India; Atlanta, Georgia; and Dublin, California, along with smaller in‑market offices that support proximity to prospects and customers.

For more information about how we help our PEO and ASO clients manage their own human capital resources and satisfy their own HR-related needs, see the section above titled “Our Services”.

Our Approach to Acquisitions

Historically, we have pursued acquisitions to expand our service capabilities, technology offerings, and supplement our growth. Our acquisition targets have included PEOs as well as HCM technology and services companies to supplement or enhance our HCM services. We intend to continue to pursue acquisitions, where appropriate, that will enable us to add new clients or WSEs, expand our presence in certain geographies or industry verticals, or expand our technology capabilities or services.

The Impact of Seasonality on Our Business

Our business is affected by seasonality in client business activity, hiring and benefit selections, health claims costs and payroll taxes:

•PEO clients generally change their payroll service providers at the beginning of the payroll tax and benefits enrollment year; as a result, we have historically experienced our highest volumes of new clients joining and terminating clients in the month of January. Our ASO clients are generally less affected by these considerations.

•WSEs select our TriNet-sponsored benefit plans during their respective open enrollment periods, which occur throughout the year. We generally experience the largest proportion of WSE benefit changes in the first and second quarters.

•Health claims costs tend to increase throughout the year as the utilization of medical services above each WSE's deductible causes our insurance costs to increase. In addition, the overall use of medical services by WSEs, including elective procedures, tends to increase later in the calendar year.

•Certain payroll tax related billings are based on annual taxable wage bases up to a set cap. Our clients frequently meet these wage base caps in the first two quarters of the year, depending on the compensation level of the relevant employees, resulting in lower related billing contributions to PSR in the latter half of the year.

Our Owned and Licensed Intellectual Property

We own or license from third parties various software and other intellectual property rights used in our business. We protect our intellectual property rights through the use of confidentiality and non-disclosure agreements with our colleagues and third-party partners and vendors as well as policies incorporated and enforceable by contract. We own registered trademarks in the United States, Australia, Canada, the United Kingdom, and the European Union covering our company name and other key trademarks that we believe are materially important to our operations. We protect our marks through federal registrations when appropriate, or otherwise through commercial use. Trademark registrations must generally be renewed every five to ten years and we renew the registration of trademarks that we deem to have continuing value to our business.

Corporate and Other Available Information

We were incorporated in 1988 as TriNet Employer Group, Inc., a California corporation. We reincorporated as TriNet Merger Corporation, a Delaware corporation, in 2000 and during that year changed our name to TriNet Group, Inc. Our principal executive office is located at One Park Place, Suite 600, Dublin, CA 94568 and our telephone number is (510) 352-5000. Our website address is www.trinet.com.

RISK FACTORS			Table of Contents

Item 1A. Risk Factors

Below is a discussion of the risks that we face and believe are significant to our business. These risks are not the only ones we face. We may face additional risks that we do not currently consider to be significant or of which we are not currently aware, and any of these risks could cause our actual results to differ materially from historical or anticipated results. You should carefully consider these risks along with the other information provided in this Form 10-K, including the information in "Management's Discussion and Analysis of Financial Condition and Results of Operations" and our accompanying consolidated financial statements, as well as the information under the heading "Cautionary Note Regarding Forward-Looking Statements" before investing in any of our securities. We may amend, supplement or add to the risk factors described below from time to time in future reports filed with the SEC.

Operational Risks

Unexpected changes in workers' compensation and health insurance costs and claims by worksite employees could harm our business.

Our insurance costs, which comprise a significant portion of our overall costs, are significantly affected by WSEs' health and workers' compensation insurance claims experience. We use fully insured risk-based, and fully insured guaranteed-cost, insurance policies provided by third-party insurance carriers. Under risk-based policies, we agree to reimburse our carriers for any claims paid within an agreed-upon per-person deductible layer up to a maximum aggregate exposure limit per policy. These deductible dollar limits and maximum limits vary by carrier and year. Under guaranteed-cost policies, our carriers establish the premiums, and we are not responsible for any deductible. Refer to Note 1 in Part II, Item 8. Financial Statements and Supplementary Data, of this Form 10-K for further discussion of these policies.

Under our risk-based health insurance policies, which make up the majority of our health plans and claims paid in 2025, we assume the risk of variability in future health claims costs for our enrollees and do not influence the use of covered services by enrollees, other than through the structural terms of such policies. We have experienced variability, and may experience variability in the future, in the amounts that we are required to pay within our deductible layer under these policies, and that variability has resulted and may continue to result in greater than expected insurance costs. This variability arises from changes to the components of MCT, defined as changes in participant use of services, including the introduction of new treatment options, changes in treatment guidelines and mandates, events, circumstances or situations that require increases in the volume of healthcare, such as a global pandemic and changes in the mix, cost of providing treatment, and timing of services provided to plan participants. MCT trends change over time, and other seasonal trends and variability may develop, which makes it difficult for us to predict this aspect of our business and our failure to accurately predict these trends could have a material adverse effect on our business, financial condition and results of operations. For example, while our insurance costs were only moderately higher than our expectations in 2025, higher medical claims had a significant impact on our results due to volume, and should plan participants continue to submit a higher number of medical claims, those claims may continue to have a significant impact on our results. Insurance costs of claims outpacing the growth in insurance services revenues in 2025 led to an increase in our insurance cost ratio (ICR), a trend driven in part by higher rates paid for outpatient and professional services as well as increased utilization of high-cost specialty drugs. This trend may continue and could further pressure our ICR and financial condition if not offset by pricing actions or successful cost containment efforts. In addition, if we underestimate future levels of healthcare cost inflation, it could increase our cost of claims, which in turn could have a material adverse effect on our financial condition and results of operations. In turn, increased pricing of our services in response to such variability has affected and may continue to affect our ability to maintain or expand our base of WSEs.

Under our fully insured workers' compensation insurance policies, we assume the risk for losses up to $1 million per claim occurrence (deductible layer). The ultimate cost of the workers’ compensation services provided will not be known until all the claims are settled. If we do not accurately predict the risks that we assume, for example, due to the factors that may impact costs described above, we may not charge adequate fees to cover our costs, which could reduce our net income and result in a material adverse effect on our business. Our ability to predict these costs is impacted by unexpected increases in frequency or severity of claims, which can vary due to changes in the cost of treatments or claim settlements.

We accrue for the estimated future costs of reimbursing our workers' compensation and health insurance carriers under our insurance policies. We use internal actuaries to develop health claims estimates, and we use external actuaries and our own experience to develop workers’ compensation estimates, but the volume and severity of claims activity is difficult to accurately predict. Estimating these accrued costs requires us to consider a number of factors, such as the components of MCT, seasonal trends and the impact of events such as the COVID-19 global pandemic, which requires significant judgment. In addition, the usefulness of historic claims data is impacted by our rates of WSE and client turnover and we renew our carrier contracts and set fees in advance of benefit periods, and thus we cannot guarantee that historic claims data will allow us to accurately estimate future costs.

In past periods, we have experienced insurance costs that were either higher or lower than our expectations and estimates. If we were to continue to experience either outcome in the future, as we expect at times we may do, it could have a material adverse effect on our business, financial condition and results of operation. Higher-than-



TRINET	15	2025 FORM 10-K


RISK FACTORS			Table of Contents

expected insurance costs result in lower net income. Because we set fees in advance of plan periods, lower-than-expected insurance costs can be an indicator that insurance costs are developing more slowly than our projections, which are reflected in our fees, and this can have a negative impact on client retention and new sales.

In addition, claims are not static, and if we subsequently receive updated information indicating that the volume and severity of insurance claims were higher or lower than previously estimated and reported, our insurance costs could be higher or lower, respectively, in that period or subsequent periods as we adjust our accrued costs accordingly, which could have a material adverse effect on our business, financial condition and results of operations. We have experienced both favorable and unfavorable insurance cost variability due to claims activity in the past and expect that, at times, we could have similar or worse experiences in the future. Refer to Critical Accounting Judgments and Estimates in Part II, Item 7. MD&A, of this Form 10-K for further discussion of these estimates.

Our co-employment relationship with our worksite employees exposes us to unique business risks.

As a co-employer of client WSEs, we assume some of the risks and obligations of an employer. For instance, at times we are required to provide access to health benefits to WSEs even when the cost of providing those benefits exceeded the service fees received from our clients. The extent of our responsibility for other aspects of our co-employer relationship with WSEs remains subject to regulatory uncertainty at the federal, state and local levels. For example, in certain states, PEOs are responsible for paying salaries, wages and related payroll taxes of WSEs, even if our clients have not timely remitted payments to us whether due to insolvency, their bank going into receivership, or other events that may be out of our control.

WSEs work in our clients' workplaces. We do not control the workplace environment of our clients. Yet, we may be subject to liability for violations of labor and employment laws, workers' compensation laws, industry-specific laws that apply to the businesses our clients operate, and other laws that apply to our clients or to employers generally. We may also be liable for acts, omissions or violations by clients or WSEs, even if we do not participate in such acts, omissions or violations.

We seek to mitigate these risks through our client agreements and insurance coverage. Our client agreements allocate responsibilities between us and our clients and provide that our clients will fund certain obligations in advance and indemnify us for any liability attributable to their own or our WSEs' conduct. However, we may not be able to effectively enforce or collect on these obligations. In addition, we maintain insurance coverage, including workers’ compensation and EPLI coverage, to limit our and our clients' exposure to various WSE-related claims. We are still responsible for deductible layers under our EPLI policies, and these policies generally exclude coverage for claims relating to the classification of employees as exempt or non-exempt, other wage and hour issues, and employment contract disputes. We cannot assure you that our insurance will be sufficient in amount or scope to cover all claims that may be asserted against us and for which we are unable to obtain indemnification from our clients.

Negative publicity relating to events or activities attributed to us or our colleagues as a result of the actions of our clients and WSEs, or others associated with them, whether or not justified, may tarnish our reputation and reduce the value of our brand, which could have a material adverse impact on our ability to attract and retain clients.

We may not realize or sustain the expected benefits from our business transformation initiatives, and these efforts could have a materially adverse effect on our business.

We have been and will be undertaking certain transformation initiatives, which are designed to evolve the technology and processes we use to support our sales and marketing efforts and our core customer-facing operational activities, enhance our customer support model, provide industry-leading benefits offerings and strengthen our talent and culture, while supporting our revenue growth, margin improvement and productivity. If we do not successfully manage and execute these initiatives, or if they are inadequate, ineffective, less effective relative to those of our competitors, or are not accepted by our clients, we may fail to meet our financial goals and achieve anticipated benefits, improvements and cost-efficient initiatives may be delayed, not sustained or not realized and our business, operations and competitive position could be adversely affected. In addition to the complexity of our efforts to expand our operations at our new office in Hyderabad, India, these initiatives, or our failure to successfully manage them, could result in unintended consequences or unforeseen costs, including distraction of our management and employees, attrition, inability to attract or retain key personnel, and reduced employee productivity, which could adversely affect our business, financial condition, and results of operations.

We expect to and will continue to devote substantial time, money and management resources to these projects. Managing these projects also typically requires changes to our internal operational, financial and management controls as well as our reporting systems and procedures. We cannot guarantee that our efforts will achieve our goals in a timely or cost-effective manner or at all, and we cannot guarantee that we can carry out these projects without a negative impact on our day-to-day operations, current service offerings and client satisfaction. If our current and future projects are delayed or unsuccessful, of if any changes to our controls, reporting systems, or procedures are deficient, prices of our services may increase, client satisfaction may suffer, we may experience significant client attrition or fail to onboard new clients at expected rates, and we may incur substantial unanticipated costs to complete these projects. Any of these outcomes could have a material adverse effect on our business, financial condition and results of operations.



TRINET	16	2025 FORM 10-K


RISK FACTORS			Table of Contents

Our SMB clients are particularly affected by volatility in the economic environment.

SMBs can be particularly susceptible to changes in the level of overall economic activity in the markets in which they operate. These businesses are often exposed to credit and cash liquidity risks, including exposure as a result of the failure of their financial institutions, that larger businesses may be able to avoid. Economic activities, increased regulations, policy changes and uncertainty may impact SMBs to a greater degree than larger business. During periods of weak economic conditions, including periods of increased inflation and increased borrowing costs, SMB failures tend to increase, and employment levels tend to decrease. During these periods, our clients can and do freeze hiring, terminate or furlough their employees, and reduce compensation and benefits levels, any of which would negatively affect our revenues and margins if we are unable to reduce our operating expenses sufficiently or quickly enough. During these periods, we have also seen and expect to continue to see, reduced demand for our services, increased client terminations, fewer new clients, and clients seeking to renegotiate our contracts and prices. In addition, our growth is partially dependent on hiring of new employees by existing clients, which may be negatively impacted during periods of tight labor markets, or may be impacted long term by technological changes including, without limitation, decreases in client headcounts driven by AI. When our clients leave us or reduce their headcount, we typically see increases in the volume and severity of unemployment claims, COBRA claims, disability claims, and workers’ compensation claims. We may be unable to recover costs related to these claims based on the fees established in our client service agreements, and any failure to recover such costs may have a material adverse effect on our business, financial condition and results of operations.

Additionally, trade policies, including tariffs or other export or import restrictions, laws, and regulations, could directly or indirectly have a material adverse effect on our customers' businesses, as well as result in economic uncertainty and downturn more generally. For example, increased tariffs or other export or import restrictions, laws, and regulations, or even uncertainty with respect to such increases, could result in cost inflation or supply chain disruption, which could in turn result in companies reducing payroll expenses, delaying hiring or ceasing hiring practices, or cutting jobs. In addition, an economic downturn could result in a weakening of the market for our services as a result of fewer new companies being formed or funded, as well as a reluctance of companies to spend on PEO or ASO services. The results of any of these could negatively impact our revenue, as well as our ability to grow and retain clients, which could have a material adverse effect on our business, financial condition and results of operations.

We lose clients for many reasons that we cannot control or easily predict and, generally, our clients sign service agreements that they can cancel on short notice.

Our standard client service agreements can generally be canceled by our clients with 30 days’ prior written notice. We regularly experience client attrition and decreases in new client sales due to a variety of factors that are difficult for us to control or predict, including the overall global and national economic conditions, client mergers and acquisitions, changes in medical utilization and related costs, client business failure and liquidity issues, the effects of competition, pricing of our services, and client decisions to administer all or a portion of their HR needs in-house without using our services. Client attrition for any of the above reasons in excess of our historic and estimated rates has had and may at times continue to have a material adverse effect on our business, financial condition and results of operations.

Geographic and industry market concentration makes our results of operations vulnerable to regional and industry-specific economic and health factors.

PEO services remain our core business. Our top five PEO markets, California, New York, Florida, Texas and Massachusetts, accounted for approximately 64% in aggregate of our paid WSEs for the year ended December 31, 2025. If any of those geographic regions suffers a downturn, even if the economy at the national level remains strong, or experiences higher than expected medical services utilization, due to regional health issues or other regional specific issues, the portion of our business attributable to clients in that region could be adversely affected, which could have a material adverse effect on our financial condition or results of operations.

In addition, most of our PEO clients operate in a relatively small number of verticals, including the technology, professional services, financial services, life sciences and not-for-profit verticals. As a result, if any of those verticals, or any industry within one of those verticals, suffers a downturn, even if the economy at the national level remains strong, the portion of our business attributable to clients in that industry could be adversely affected, which could have a material adverse effect on our business, financial condition or results of operations.

If we are unable to attract, maintain and manage qualified personnel, including our sales force, our business may be harmed.

To succeed, we must be able to attract and retain highly motivated and qualified personnel. Competition for skilled employees is intense, and like many businesses, we are susceptible to fluctuations in the labor market. For example, as we continue to expand our operations in India, we face the challenges of a different labor market. If we are unable to attract and retain qualified personnel, in either or both of the US and India (or any other jurisdiction into which we expand), our business may suffer.

For example, for a variety of reasons, including due to changes in industry or client focus, compensation structure, third-party competition for sales talent and other factors we have experienced elevated sales force attrition in the



TRINET	17	2025 FORM 10-K


RISK FACTORS			Table of Contents

past and may experience it in the future. Newly hired sales personnel are typically not productive for some period of time following their hiring, which results in increased near-term costs to us relative to their actual sales contributions during this period. If we are unable to effectively train and maintain an adequately seasoned and sized sales force, new client onboarding will not increase at the rate that we anticipate, which could have a material adverse effect on our business, financial condition and results of operations. Political changes in any jurisdiction may also impact our ability to attract or retain talent, and have a material adverse effect on our business, financial condition and results of operations.

We face risks associated with our international operations.

In August 2024, we opened our office in Hyderabad, India, which increased the size and scale of our India-based workforce and operations. A disruption to, or our failure to successfully integrate, our operations in India could have a material adverse effect on our business, financial condition and results of operations. Our current and potential future international operations are subject to certain risks, including:

•fluctuations in foreign currency exchange rates and global market volatility;

•difficulties and costs of staffing and managing foreign operations, including cultural and language differences and additional employment regulations, union workforce negotiations and potential disputes;

•geopolitical, economic or social instability or military conflict;

•natural disasters, terrorist attacks and other events over which we have no control;

•compliance with local laws and regulations, including privacy and security laws and regulations;

•compliance with laws governing doing business outside the United States, including foreign or domestic legal and regulatory requirements resulting in the imposition of new or more onerous sanctions and anti-corruption laws, export and import controls or other trade restrictions, tariffs, duties, taxes, embargoes, exchange or other government controls;

•laws and business practices favoring local companies; and

•management of potentially adverse tax consequences from India, the United States, or both, as a result of our multi-jurisdiction operations.

Any of these risks, in particular when taken together with our ongoing business transformation initiatives, could have an adverse impact on our ability to successfully manage our business and consequently have a material adverse effect on our business, financial condition and results of operations.

Any failure in the business systems or service centers that we or our service providers rely upon, could negatively impact our clients, harm our reputation and expose us to significant, unanticipated liability.

Our business is highly dependent on in-house and third-party business systems and service centers. The operation of our business relies on the complex integration of numerous hardware and software subsystems across several service centers to manage a large volume of daily client and WSE transactions. For example, we rely on software systems, including the software systems used by our banking institutions, to process payroll, payroll tax and benefits data and make related payments, and to access insurance carrier networks and databases that manage WSE benefits and claims. These software systems run on computer hardware that we or our service providers house in various service centers.

These centers and systems have been, and could be disrupted by equipment failures, computer server or systems failures, network outages, ransomware attacks and other malicious acts, software errors or defects, vendor performance problems, banking failures, power failures, natural disasters, terrorist actions or similar events. We have, for example, experienced office closures on the east coast due to hurricane and storm threats, in Texas due to climate-related power grid issues, and in California due to increased wildfire threats. Our offices and service centers in these and other locations will continue to face the risk of closure or damage in the future due to climate related events.

Any such disruption, even if only for a short period of time and even if we are not at fault, can have a significant impact on our clients and WSEs by preventing us from timely processing payroll, paying payroll taxes and other liabilities and otherwise disrupting our business operations. As a result, any such disruption could cause us to lose clients, negatively impact our ability to attract new clients, and reduce our revenues and increase our costs, any of which could result in a material adverse effect on our reputation, business and results of operations.

Changes in our insurance coverage, or in our relationships with key insurance carriers, could harm our business.

Our success depends in part on our ability to maintain competitive health and workers' compensation coverage options and insurance rates through well-known insurance carriers. If we are unable to maintain competitive insurance rates or obtain popular and desirable coverage plans through well-known insurance carriers, it could affect our ability to attract and retain clients, which could have a material adverse effect on our business. Where we sponsor insurance coverage and we are not responsible for any deductibles, our carriers set the fixed cost of the plan, which may lead to uncompetitive fees. Even where we sponsor insurance under which we are responsible for deductibles, we may not be able to control our costs in a way that would make our fees competitive.



TRINET	18	2025 FORM 10-K


RISK FACTORS			Table of Contents

In addition, broad adoption of our services in certain geographic regions or industries may make it more difficult for us to obtain competitive health and/or workers' compensation insurance rates due to concentration of clients within a particular region or industry. For example, we have significant concentrations of PEO clients in California, New York, Florida, Texas and Massachusetts, which account for approximately 64% in aggregate of our paid WSEs for the year ended December 31, 2025. The loss of any one or more of our key insurance vendors in these areas, including, without limitation, for any legal, political, or economic reasons, or our inability to partner with the most desirable carriers in these areas, could have a material adverse effect on our financial condition and results of operations.

We must continue to work to improve our services to meet the expectations of our clients and regulators, or we may lose our clients and materially harm our business.

In order to attract and retain clients, we believe that we must compete in our industry effectively on the basis of the value proposition that we deliver to our clients, which includes

•client experience and satisfaction,

•the relevance and cost-effectiveness of our PEO benefit plans,

•our PEO vertical market expertise,

•our service and product pricing,

•our brand awareness and reputation,

•our ability to innovate, provide innovative solutions and software and technology platforms and respond to client needs and regulatory mandates rapidly,

•the performance, reliability and ease of use of our online and mobile solutions, software and technology platforms, and

•our human resources subject matter expertise.

The expectations of our clients and prospective clients in these areas change over time as a result of many factors outside of our control, such as competition, regulatory and technical changes, technological changes, and changing trends in the demands employees place on SMB employers.

To satisfy client expectations and regulatory requirements, we must timely and effectively identify and develop, or license and contract appropriate technologies and services, and incorporate such technologies and services into the solutions that we provide. We generally have limited visibility into the operations, strategies and future business plans of our customers, which stem from a variety of different industries and segments of the economy. Accordingly, it may be difficult to anticipate trends and tailor our services to our clients' evolving expectations, which could negatively affect our financial condition and results of operations.

In addition, new services or upgrades may not be released according to schedule or may contain defects when released. If our new technologies and services perform poorly, or fail to satisfy regulatory requirements, we could experience client dissatisfaction, adverse publicity, loss of sales, and client claims against us, any of which could materially harm our business. Even where we can satisfy client expectations and regulatory requirements, we may not be able to do so on a cost-effective basis, which could have a material adverse effect on our financial condition and our results of operations. We could lose market share if our competitors develop superior technologies and services or satisfy client or regulatory demands before we are able to do so. If we are unable to satisfy the evolving technology and service expectations and regulatory requirements, then we may experience lower client satisfaction, fewer new clients and higher client attrition, which could have a material adverse effect on our business.

We have acquired, and may in the future acquire, other businesses and technologies, which can divert management's attention and create integration risks and other risks for our business.

We have completed numerous acquisitions of other businesses and technologies in the past, and we expect that we will continue to pursue future acquisitions. Acquisitions involve numerous risks, some of which we have experienced in the past and which we may experience in the future, including:

•over-valuing and over-paying for businesses and technologies,

•increased indebtedness,

•increased operating costs and unanticipated costs to successfully integrate the clients and WSEs, operations, systems, technologies, services, personnel and other stakeholders of the acquired business,

•establishing or maintaining required internal controls, procedures and policies for the acquired business,

•unanticipated costs and risks arising from the unique corporate culture and risk appetite of acquired businesses,

•diversion of management’s attention from other business concerns,

•unforeseen liabilities or litigation resulting from the activities of the acquired business,



TRINET	19	2025 FORM 10-K


RISK FACTORS			Table of Contents

•insufficient revenues, insurance or seller indemnification to offset increased expenses associated with the acquisitions and unanticipated liabilities of the acquired businesses,

•impairment of intangible assets,

•entering markets in which we have no prior experience and may not succeed, and

•potential loss of key employees or key clients of the acquired business as a result of the acquisition or integration of the acquired business.

We have experienced increased operating costs to resolve the challenges of prior acquisitions. If we fail to appropriately integrate any acquired business, we may fail to achieve our growth, service enhancement or operational efficiency objectives, and our business, results of operations and financial condition could be harmed.

Our industry is competitive, which may limit our ability to maintain or increase our market share or improve our results of operations.

We face significant competition on a national and regional level from other PEOs, and ASOs that do not use co-employment relationships, as well as from other existing, and potential, companies and industries that service, or may in the future service, client HCM needs. Refer to the heading “Competition” under Part I, Item 1. Business, above for more details. Our competitors, regardless of industry, may have greater marketing and financial resources than we have, and may be better positioned than we are in certain markets. Increased competition in our industry could result in price reductions or loss of market share, any of which could harm our business. We expect that we will continue to experience competitive pricing pressure and competition from new technologies and HCM service models, any one of which could have a material adverse effect on our business.

We may not be able to keep pace with changes in technology, including as a result of AI, or provide timely enhancements to our solutions and support.

The market for our solutions is characterized by rapid technological advancements such as AI, including without limitation, AI systems performing the roles historically allocated to human HR resources, changes in customer requirements, frequent new product introductions and enhancements, and changing industry standards. To maintain our growth strategy, we must adapt and respond to technological advances and technological requirements of our clients, including leveraging AI in our solutions. For example, we have been developing TriNet Assistant, which we expect to launch in 2026, an AI HR tool where customers will be able to ask and receive responses to a broad spectrum of HR questions. There can be no assurances, however, that the leveraging of AI within our solutions will be successful. Our competitors and other third parties may incorporate AI into their products and offerings more quickly or more successfully than us, which could impair our ability to compete effectively, cause us to lose some or all of our investments in developing these solutions, and adversely affect our results of operations. Additionally, if the content, analyses, or recommendations that AI applications assist in producing are, or are alleged to be, inaccurate, deficient, or biased, our business, financial condition, and results of operations may be adversely affected. Further, the use of AI applications may result in cybersecurity incidents that implicate the personal data of customers analyzed within such applications. Any such cybersecurity incidents related to our use of AI applications to analyze personal data could adversely affect our reputation and results of operations.

Accordingly, our future success will depend on our ability to: enhance our current solutions and introduce new solutions in order to keep pace with solutions offered by our competitors, and to market those solutions effectively to existing and potential clients. We continue to make significant investments related to the development of new technology. If our systems become outdated, it may negatively impact our ability to meet performance expectations related to quality, time to market, cost and innovation relative to our competitors. The failure to provide a more efficient and user-friendly customer-facing digital experience across internet and mobile platforms as well as in physical locations may adversely impact our business and operating results. We cannot assure you that our efforts to update and integrate systems will be successful. If we do not integrate and update our systems in a timely manner, or if our investments in technology fail to provide the expected results, there could be a material adverse effect to our business and results of operations.

Data Privacy and Security Risks

Cyber-attacks, breaches, disclosures or other data-related incidents could result in reduced revenue, increased costs, liability claims, regulatory penalties, regulatory disclosure requirements and damage to our reputation.

We and our third-party service providers and subcontractors collect, store, use, retain, disclose, transfer and process a significant amount of confidential, sensitive and personal information from and about our actual and potential clients, WSEs and colleagues, including bank account numbers, social security numbers, tax information, PHI, health claim information, retirement account information, and payroll data. We also collect significant amounts of funds from the accounts of our clients and transmit them to their employees, tax authorities and other payees.

Due to the size and complexity of our technology platform and services, the amount of confidential, sensitive and personal information that we store, we and our service providers are potentially susceptible to a variety of intentional or inadvertent cyber-attacks, breaches, disclosures and other data-related incidents and threats.



TRINET	20	2025 FORM 10-K


RISK FACTORS			Table of Contents

Cybersecurity threats can take a variety of forms. Malicious actors may develop and deploy viruses, worms and other malicious software programs that attack our networks and data centers or those of our service providers. Malicious actors may also direct social engineering, phishing, credential stuffing, ransomware, denial or degradation of service attacks and similar types of attacks against any or all of us, our clients and our service providers. Other threats include inadvertent security breaches or disclosures, misuse or unauthorized access or other improper actions by our colleagues, clients, WSEs, service providers and other business partners. Cyber-attacks, breaches, disclosures and other data-related incidents are increasing in frequency and evolving in nature (including due to the use of AI). In addition, new computing technologies, including quantum computing, new discoveries in the field of cryptography or other developments could result in a compromise or breach of the algorithms we or our authorized third parties use or have used to encrypt or protect data. While we devote substantial time and resources to training our colleagues to identify and avoid such incidents, no training or cybersecurity program can offer absolute protection against such attacks and incidents.

Any actual or attempted cyber-attack, breach, disclosure or other data-related incident, could result in data loss, the unauthorized access or use of personally identifiable information, theft of sensitive information or our clients’ or our own funds, or business interruption, which could have a material adverse effect on our business, reputation, financial condition or results of operation. Any delays or failures caused by network outages, software or hardware failures, or other data processing disruptions, could result in our inability to provide services in a timely manner or at all. The speed to closure of significant cybersecurity incidents may be influenced by the cooperation of government or law enforcement agencies. In addition, since the security of our information technology infrastructure is an important consideration in our clients’ purchasing decisions, and public perception of, or even inaccurate or unfounded rumors of, any such cyber-attacks, breaches, disclosures, or other data-related incidents, could have a material adverse effect on our business, reputation, financial condition or results of operation.

Although we maintain insurance coverage for such events, the amount of our insurance may not cover these costs, and we cannot be certain that cyber insurance will continue to be available to us on economically reasonable terms, or at all, or that any insurer will not deny coverage as to any future claim.

We do not need to be the direct target of such cyber-attacks, breaches, disclosures or other data-related incidents, for them to have a material adverse effect on our operations. A cyber-attack on a key third-party software service provider, or a new vulnerability identified in software that we use, could disrupt our services or compromise client data entrusted to that service provider. Similar cyber-attacks, breaches, disclosures and other data-related incidents, including those resulting from a vulnerability, involving a client could also result in access to our systems. Any such incidents, even if not initially directed at us, could also have a material adverse effect on our business operations, result in liability, fines and penalties or other regulatory sanctions, a loss of confidence in our ability to provide our services, and/or harm our reputation and relationships with current or potential clients.

We, our clients and our service providers have been the victims of cyber-attacks, breaches, disclosure or other data-related incidents, in the past that led to disclosure of the confidential, sensitive or personal information we possess, and we, our clients and our service providers expect to be victims again in the future. Similarly, we and our service providers have experienced disruption to, or unauthorized access to, our networks, applications, bank accounts and other key systems in the past and similar events may occur again in the future. We have reported data breaches to regulators, affected individuals, clients and other third parties in the past and we expect to do so in the future as appropriate. While we do not believe that any such past events constitute a material cybersecurity incident or resulted in material expenditures, future events could result in a material adverse impact on our operations. For more information regarding our analysis of material cybersecurity incidents, refer to Part I, Item 1C. Cybersecurity.

We must comply with constantly-evolving privacy, data protection, AI and cybersecurity laws and regulations, which may require substantial costs or changes to our business, and any actual or perceived compliance failure could result in reduced revenue, increased costs, liability claims, regulatory penalties, and damage to our reputation.

We are subject to various international, federal, state and local laws, rules, and regulations, as well as contractual obligations, relating to the collection, storage, use, retention, security, disclosure, transfer and other processing of confidential, sensitive and personal information. Existing laws and regulations are constantly evolving, and new laws and regulations that apply to our business are being introduced at every level of government inside and outside of the United States.

Depending on the applicable jurisdiction, these laws may be more stringent or broader in scope, or offer greater individual rights, with respect to confidential, sensitive and personal information than federal, international or other state laws, and such laws may differ from each other, which may complicate compliance efforts, requiring attention to changing regulatory requirements. As the patchwork of privacy laws to which we are subject becomes increasingly complex, the cost of complying with all of the requirements will rise and we cannot guarantee our compliance efforts will be successful.

We believe that providing insights and content from data, including AI and ML, will become increasingly important to the value that our solutions and services deliver to our clients are exploring how best to integrate generative AI technologies and develop and deploy capabilities that are beneficial to our clients and WSEs. In recent years, legislation that creates obligations with respect to the development and/or use of AI has been adopted or is under

consideration in the U.S. at both the federal and state level, as well as abroad. In addition, self-regulatory frameworks like the National Institute of Standards and Technology AI Risk Management Framework are being promulgated and adherence to such regulatory frameworks may become an industry standard or a client expectation. As a result, the ability to provide data-driven insights and otherwise leverage AI and ML may be constrained by current or future laws (including product liability regimes), regulatory or self-regulatory requirements or ethical considerations, including our own guiding ethical principles regarding AI and ML, that could restrict or impose burdensome and costly requirements on our ability to leverage data and/or these technologies in innovative ways. Our use of generative AI in our solutions and operations also introduces additional risks, including risks related to accuracy, bias, transparency, security, and privacy. For example, if data used to train a model or the model’s output is inaccurate or biased, or alleged to be inaccurate or biased, we could be subject to reputational damage or litigation.

For details regarding these data privacy and security laws and regulations discussed above and that apply to our operations, refer to Part I, Item 1. Business, of this Form 10-K, under the heading “The Laws and Regulations that affect Our Business: Data Privacy and Security Regulations”. Complying with these and any other data privacy and security laws, rules and regulations, and with any new laws or regulations or changes to existing laws, could cause us to incur substantial costs or require us to change our business practices in a manner adverse to our business, divert resources from other initiatives and projects, and restrict the way products and services involving data are offered, all of which may have a material adverse effect on our business. Despite our efforts, in the future we may be unable to make required changes and modifications to our business practices in a commercially reasonable manner, or at all. We may be exposed to significant penalties or liability for non-compliance, the possibility of fines, lawsuits (including class action privacy litigation), regulatory investigations, criminal or civil sanctions, audits, adverse media coverage, public censure, other claims, significant costs for remediation and damage to our reputation, all of which could have a material adverse effect on our business and operations. Any inability, or the perception of any inability, to adequately address data privacy or data-related concerns, even if unfounded, or to comply with applicable laws, regulations, standards and other obligations relating to data privacy and security, could result in additional cost and liability to us, damage our relationships with clients and have a material adverse effect on our business.

As a sponsor of employee benefit plans with access to certain PHI, we are subject to regulation at the federal level, including under the HIPAA and the HITECH Act. HIPAA contains restrictions and health data privacy, security and breach notification requirements with respect to the use and disclosure of PHI. There are penalties and fines for HIPAA violations.

Legal and Compliance Risks

Our business is subject to numerous complex laws, and changes in, uncertainty regarding, or adverse application of these laws could negatively affect our business.

The services we provide to our clients are subject to numerous complex federal, state and local laws and regulations. These laws and regulations cover an extensive range of topics, including employer status, employee and independent contractor classifications, employee benefits, health and retirement plans, workers' compensation, banking and money transmission, employment and payroll tax, worksite safety, insurance, wage and hour, anti-discrimination, and many topics specific to the industries of our clients. Many of these laws do not specifically address PEOs or co-employment relationships, and regulators are often unfamiliar with the PEO industry and co-employment relationships, which can lead to unpredictable application, interpretation and enforcement of these laws and regulations at the federal, state and local levels in relation to our business. Our ASO services can also be subject to complex federal, state and local laws and regulations regarding payroll agents, employment and payroll taxes, insurance producers, banking and money transmission, and other licensing requirements. The tax credit support services we provide are also subject to federal, state and local regulations regarding tax preparation and practice that limit the services we can provide to SMBs. While regulations governing ASO services and tax credit support services do not involve the complexity of a co-employment relationship, these services are in some ways also highly regulated and such regulations can, and do, change regularly at the federal, state and local levels.

Any new laws, changes in existing laws, or any adverse application, interpretation or enforcement of new or existing laws, whether they apply to employers generally or specifically to PEOs or to our co-employment relationships could:

•reduce or eliminate the value and benefits that clients realize by using our services,

•change or eliminate the types of services we provide,

•require us to make significant changes to how we do business and provide services,

•require us to modify our current business practices or operations,

•affect the extent and type of employee benefits that employers and co-employers can or must provide employees,

•alter the amount, timing and type of taxes employers, co-employers, clients and WSEs are required to pay and that we must manage for and collect from our clients,



TRINET	22	2025 FORM 10-K


RISK FACTORS			Table of Contents

•increase the cost and complexity of the licensing requirements for our business operations,

•cause us to modify how we earn interest from client funds, which could reduce the income we earn from those funds,

•create or increase our liability and responsibilities to our clients and WSEs, and/or

•mandate new compliance requirements, disclosures or services.

Any of the above could have a material adverse effect on our business, financial condition and results of operations.

For example, we have seen a growing trend, particularly at the federal level, of using payroll tax credits, deferrals and other related payroll tax programs as a mechanism for incentivizing SMB development and economic recovery. These programs are popular because they allow SMBs, which often have income tax losses, to realize benefits via payroll tax reductions, rather than income tax reductions. However, these programs have generally not been designed with the PEO industry in mind and rely on calculations contained in client income tax returns which PEOs do not process in their role as the co-employer or other client data that cannot be verified by a PEO, even though the resulting tax benefits are processed through the PEO’s payroll tax returns. Because minimal guidance exists in the statutes that create these programs, they are subject to broad and varied agency interpretation and application. In addition, the processes used to evaluate payroll tax filings are designed with individual taxpayers in mind, not PEOs that aggregate the filings of many clients, which can further increase varied interpretation by agencies and make it difficult to predict their interpretation and application.

One of these programs includes the 2015 PATH Act, which allows SMBs to use R&D tax credits submitted on the SMB’s income tax return to reduce the SMB’s payroll taxes. The IRS has taken positions that we and other PEOs, rather than clients, are responsible for client errors and repaying rejected tax credit claims under these and similar programs. While our clients are contractually responsible for repaying us for any rejected tax credits under these programs, a contract does not guarantee our ability to recover rejected tax credits and any failure to recover rejected tax credits from our clients would increase our operating expenses, which could result in a material adverse effect on our financial condition and results of operations. Similarly, the IRS has taken positions that the tax benefits under some of these programs should be calculated on an aggregate PEO, rather than individual client, basis, which can limit whether and how we obtain credits for our clients. We cannot predict how these positions will ultimately be resolved and if they are resolved unfavorably, we may be forced to discontinue supporting some or all of these programs, incur tax expenses that we cannot recover from our clients, and divert management’s attention to defending our positions, any one of which could have a material adverse effect on our ability to attract and retain SMB clients or on our business, financial condition and results of operations.

In addition, many states have also implemented assistance programs, such as mandatory employee leave requirements and other employment- and employment tax-related incentives. Our SMB clients rely on us to help them take advantage of these programs, and new laws, regulations and agency or judicial interpretations of these laws could change or eliminate existing programs at any time, which could force us to discontinue supporting these programs or incur liability that we cannot recover from our clients, which could cause us to lose clients and have a material adverse effect on our business, financial condition and results of operations.

Changing laws and regulations governing health insurance and other traditional employee benefits at the federal, state and local level could negatively affect our business.

Changes to and continued uncertainty regarding the implementation and future of health care reform in the United States, at the federal, state and local level, has the potential to substantially change the health insurance market for SMBs and how such employers provide health insurance to their employees, which could have a materially adverse effect on how we provide our sponsored health benefits to our WSEs, and our ability to attract and retain our clients. In addition, changes at the federal, state and local level to the laws and regulations regarding other traditional employee benefits, such as retirement and workers’ compensation benefits, also have the potential to substantially change the types of benefit programs that are available to SMBs and that we and other PEOs may be required to offer. Our ability to comply with, and adapt our service offerings to take advantage of, any such changes could require significant additional costs, divert management attention, or be prohibitive based on cost, technology or other factors, which could result in a material adverse effect on our business, financial condition and results of operations.

If we are not recognized as an employer of our worksite employees, and if our benefit plans are deemed to not satisfy plan requirements, under federal and state regulations, we and our clients could be adversely impacted.

In order to sponsor some of our most important employee benefit plan offerings for WSEs, including health plans, we must qualify as the employer of WSEs, and our plans must qualify as employer-sponsored plans, under applicable provisions of the Code and ERISA. In particular, our status as the employer for the purposes of ERISA is important because ERISA preempts state laws that otherwise might apply to, and limit, our benefit plan offerings.

The definition of employer under the Code and ERISA is not uniform, and is defined in part by different facts and circumstances tests, and there is no definitive judicial interpretation of employer in the context of PEOs. Generally, the tests used under the Code or ERISA are designed to evaluate whether an individual is an independent contractor or employee, and they confer substantial weight to whether a purported employer has the right to direct



TRINET	23	2025 FORM 10-K


RISK FACTORS			Table of Contents

and control the details of an individual's work. Some factors that may be considered important under these tests have included the employer’s degree of behavioral control (for example the extent of instructions, training and evaluation of the work), financial control and the economic aspects of the work relationship, the type of relationship, as evidenced by the specific contract, if any, whether employee benefits are provided, whether the work is indefinite in duration or project-based, and whether it is a regular part of the employer’s business.

In our opinion, we qualify as the sole employer of WSEs for the purposes of Sections 3(5) and 3(40) of ERISA and that our health plans are single-employer plans that, as such, are entitled to ERISA’s preemption of state law. However, the DOL routinely audits employee benefit plan offerings of employers, and in one routine audit of one of TriNet’s health plans that concluded in 2021, the DOL indicated that while it agrees that we are an employer for ERISA purposes, it believes that wherever there is more than one employer of a WSE, no employer may qualify as a single employer for ERISA purposes. Similarly, in 2022, the DOL revised an existing publication regarding regulation of MEWAs and added a new section stating its view that a PEO arrangement offering health coverage to more than one client is a MEWA under Section 3(40) of ERISA. This DOL interpretation is contrary to our interpretation of the applicable ERISA facts and circumstances test, and it also is contrary to the position taken by other national PEOs.

We will continue to vigorously defend our opinion that we are the sole employer of WSEs for the purposes of Section 3(5) and 3(40) of ERISA, and therefore that our health plans are single employer plans entitled to ERISA’s preemption of applicable state laws. Although we do not currently have any ongoing DOL audit on this issue, we have received requests for information on the issue from other government agencies. It is possible that these requests, or future DOL audits, could lead a government agency to disagree with the Company's interpretation. If it were ultimately determined that health plans we sponsor are multiple employer plans and subject to potential regulation at the state level, we would likely adjust our business model and the manner in which we provide employee health benefits to WSEs. Any such outcome or adjustment would require significant investment in time, cost and management attention and would have an adverse impact on our clients and WSEs and the type of products and services we provide to them, which could have a material adverse effect on our business and results of operations.

As the employer of WSEs under ERISA, we must manage our plans in accordance with ERISA requirements, which could impact how we fulfill plan obligations, how we price services, the features of our benefit plans, and how we administer and operate our plans. We believe that our benefit plans satisfy all applicable ERISA requirements, but if it were ultimately determined that we fail to satisfy any such requirements, we would likely be required to adjust our business model, including with respect to each of the areas outlined above, and could be subject to material fines or penalties. Any such consequence may result in a material adverse effect on our business and results of operations.

We have seen state efforts to regulate PEO health plans. For example, legislation and proposed rules in New Mexico seek to prevent WSEs of small employers from participation in PEO sponsored large group market health plans, with exception for plans the PEOs register as MEWAs under state law. These rules, and legislation, and any other new or changed rules that treat PEO health plans as multiple employer plans, restrict PEO fees with carriers or that limit the availability of PEO benefit plans, if upheld to be legally valid and applicable to our PEO health plans, would likely require us to adjust our business model in the states with such rules, including the manner in which we provide employee health benefits to WSEs and price our services, and could result in material fines or penalties. Any such outcome or adjustment would require significant investment in time, cost and management attention and would have a material impact on our clients and WSEs and the type of products and services we provide to them, which could have a material adverse effect on our business and results of operations.

Similarly, to qualify for favorable tax treatment under the Code, certain employee benefit plans, such as 401(k) retirement plans and cafeteria plans, must be established and maintained by an employer for the exclusive benefit of its employees. All of our 401(k) retirement plans are operated pursuant to guidance provided by the IRS and have received favorable determination letters from the IRS confirming their tax-qualified status. However, the IRS uses its own complex, multi-factor test to ascertain whether an employment relationship exists between a worker and a purported employer. Although we believe that we qualify as an employer of WSEs under the Code, we cannot assure you that the IRS will not challenge our position or continue to provide favorable determination letters. Moreover, the IRS's 401(k) guidance and qualification requirements are not applicable to the operation of our cafeteria plans.

Further, if we are not recognized as an employer of our WSEs under the Code or by any state tax authority, we may be required to change the method by which we report and remit payroll taxes to the IRS or such tax authorities. Such changes could have a material adverse effect on our business and results of operations.

The definition of employers, employees and independent contractors is evolving. Changes to the laws and regulations that govern what it means to be an employer or an employee may require us to make significant changes in our operations and may negatively affect our business.

Views on employers, employees and independent contractors continue to change at federal, state and local levels. Regulations that change existing definitions and classifications of employers, employees and independent contractors could affect the types of client employees we can support through our PEO and ASO services, the way



TRINET	24	2025 FORM 10-K


RISK FACTORS			Table of Contents

in which we provide our sponsored benefits to our WSEs, the way in which we report and remit payroll taxes to tax authorities, and our legal liability for the actions and inactions of our clients, which may negatively impact client demand for the services we provide, require us to modify or change how we operate our business and have a material adverse effect on our business and results of operations.

Standards for determining joint employer status vary from law to law and state to state. Joint employment is not the same as co-employment, and we do not believe that we are a joint employer under any law or rule, or that these rule changes impact our status as a co-employer. However, continuing uncertainty regarding independent contractor and joint employer status could still result in increased regulatory and worker claims, which could divert management attention and cause us to incur additional and potentially material costs to defend.

Remote work continues to be widely used by employers across the country. The laws and regulations that govern employees were not drafted with remote workers in mind and changes in, uncertainty regarding, or adverse application of these laws could negatively affect our business.

Many employees, including WSEs, are working from home. SMBs, including our clients, have hired and continue to hire employees in locations where they have not previously had employees, and/or permitting existing employees to relocate to other locations and work entirely remotely. Other employees may work at home in one state or city some of the time and in an office in another state or city at other times. The work location and residence of an employee can create confusion regarding the federal, state and local laws that apply, including labor and employment, payroll and payroll tax, and unemployment laws. For example, it can be difficult to determine the amount of payroll and unemployment taxes that must be paid when employees spend part of their time working from home in one state and part of their time working in an office in another state. Regulations regarding payroll and unemployment taxes for such workers are still evolving, which creates a risk that states will disagree about the taxes that must be paid, or the employment laws that must apply, in these situations. New laws, changes in laws or adverse application or interpretation of laws that depend on the residence and work location of WSEs could reduce or eliminate the attractiveness of our services, significantly increase our compliance costs and the cost to provide our services, or require us to make substantial changes to the way in which we operate, and any one of these outcomes could result in a material adverse effect on our financial condition and results of operations.

Even where remote workers live and work in the same state and city, as a co-employer of WSEs, our PEO services are open to the risk that new laws, changes in laws or adverse application or interpretation of laws will expand PEO responsibility for remote WSEs. We may see expansions of PEO responsibility and we cannot guarantee that we will be able to recover compliance costs related to such expansions from our clients, which could have a material adverse effect on our business.

If we do not comply with our regulatory license requirements, or if we are deemed to be operating in various non-PEO licensed industries without the required licenses, we and our clients could be adversely impacted.

Most states require PEOs to hold a license and we are licensed as a PEO in all states that require such licenses. If we are not able to satisfy existing or future PEO licensing requirements or other applicable regulations in any state, we may be prohibited from doing business in that state, including having any clients within that state.

State regulatory authorities generally impose licensing requirements on companies acting as insurance agents or third-party administrators, such as those that handle health or retirement plan funding and claim processing. TriNet does not provide broker insurance, but we do maintain producer licenses in all 50 states and select U.S. territories for our ASO services and for our OMS product family, which offers clients the option to receive PEO services from TriNet while sponsoring their own health benefits obtained through brokers. Other state regulatory authorities impose licensing requirements on companies involved in the transmission of cash, such as banks, and other money transmitters. We do not believe that our current activities require any such licenses. Businesses similar to our ASO services have been subject to such licensing requirements in the past and although we believe that our operations have been designed to be compliant and avoid such requirements, we cannot guarantee that all regulators will agree. If regulatory authorities in any state determine that we are acting as an insurance agent, third-party administrator, money transmitter, or as any other regulated industry other than a PEO, we may need to hire additional personnel to manage regulatory compliance and pay annual regulatory fees, which could have a material adverse effect on our financial condition and results of operations.

We may be adversely impacted by any failure of third-party service providers to perform their functions.

As part of providing services to clients, we rely on a number of third-party service providers. Service providers include, but are not limited to, banks used to electronically transfer funds from clients to their employees, information technology vendors, and couriers used to deliver client payroll checks. Failure by these service providers, for any reason, to deliver their services in a timely manner and in compliance with applicable laws and regulations could result in material interruptions to our operations, impact client relations, and result in significant penalties or liabilities to us.



TRINET	25	2025 FORM 10-K


RISK FACTORS			Table of Contents

Failure to comply with anti-corruption laws and regulations, economic and trade sanctions, and similar laws could have a materially adverse effect on our reputation, results of operations or financial condition, or have other adverse consequences.

We are required to comply with regulations administered by multi-national bodies and governmental agencies worldwide including, but not limited to, the economic sanctions and embargo programs administered by the Office of Foreign Assets Control (“OFAC”), and the Foreign Corrupt Practices Act (“FCPA”). OFAC places restrictions on the sale or export of certain products and services to certain countries and persons. A violation of a sanction or embargo program, or of the FCPA, or similar laws prohibiting certain payments to governmental officials, could subject us, and individual employees, to regulatory enforcement action as well as significant civil and criminal penalties which could adversely impact our business and operations.

The growth of our international operations also subjects us to additional risks, such as compliance with foreign laws and regulations. The enactment of new laws and regulations, modifications of existing laws and regulations, or the adverse application or interpretation of new or existing laws or regulations can adversely affect our business. Additionally, as federal, state, and international regulations become more complex, the risk that we may be unable to comply with those regulations increases, particularly in the event there are different or additional regulatory standards in different jurisdictions.

We are subject to legal and tax proceedings that may result in adverse outcomes.

We are subject to claims, lawsuits, government investigations, and other legal and regulatory proceedings arising from the ordinary course of our business. Refer to Note 9 in Part II, Item 8. Financial Statements and Supplementary Data, of this Form 10-K for additional information. Current and future legal proceedings may result in substantial costs and may divert management’s attention and resources, which may seriously harm our business, results of operations, financial condition and liquidity.

In addition, the tax authorities in the U.S. regularly examine our tax returns. Refer to Note 12 in Part II, Item 8. Financial Statements and Supplementary Data, of this Form 10-K for additional details regarding tax examinations and disputes. The ultimate outcome of tax examinations and disputes cannot be predicted with certainty. Should the IRS or other tax authorities assess additional taxes as a result of any audit or examination, we may be required to record charges to operations that could have a material impact on our results of operations, financial position or cash flows.

Financial and Stock Ownership Risks

Our results of operations and stock price may fluctuate as a result of numerous factors, many of which are outside of our control.

Our operating results and stock price have fluctuated and may continue to fluctuate and vary based upon a variety of factors, many of which are not within our control, including, without limitation:

•the volume and severity of health and workers' compensation insurance claims made by our WSEs, recorded as part of our insurance costs, and the timing of related claims information provided by our insurance carriers,

•the amount and timing of our insurance premiums and costs, operating expenses and capital expenditures,

•the number of our new clients and the number of WSEs employed by each new client,

•the retention or loss of existing clients, for any reason, including third-party acquisition,

•a reduction in the number of WSEs employed by or a reduction in WSE hiring by existing clients,

•the timing of client payments and payment defaults by clients,

•the costs associated with our acquisitions of companies, assets and technologies,

•any unanticipated expenses, such as litigation or other dispute-related settlement payments and compliance expenses arising from changes in regulations or regulatory enforcement,

•any expenses we incur for geographic and service expansion and service enhancements,

•any changes in laws or adverse interpretation or enforcement of laws, which may require us to change the manner in which we operate and/or increase our regulatory compliance costs,

•the issuance of common stock or debt to pay for future acquisitions, which could dilute our stockholders or subject us to significant debt service obligations, and

•the repurchase of our common stock under our stock repurchase program or otherwise, which could impact earnings per share and increase the ownership percentage of non-participating stockholders.

In addition, the trading price of our common stock is subject to fluctuation in response to a variety of factors, including the factors above and below, many of which are not within our control, including, without limitation:

•the overall performance of the equity markets, our competitors or our common stock,



TRINET	26	2025 FORM 10-K


RISK FACTORS			Table of Contents

•any trading activity by our directors, executive officers and significant stockholders,

•the economy as a whole, and its impact on SMBs and our clients, and

•any significant changes in the liquidity of our common stock.

Many of the above factors are discussed in more detail elsewhere in this Risk Factors section and in Part II, Item 7. MD&A, of this Form 10-K. The variability and unpredictability of these factors have in the past and could in the future cause us to fail to meet our expectations and the expectations of investors and any industry analysts who cover our shares, which could result in a decline in our share price and reduced liquidity in our shares. In addition, the occurrence of one or more of these factors might cause our results of operations to vary widely, which could lead to negative impacts on our margins, short-term liquidity, and our ability to retain or attract key personnel, and could cause other unanticipated issues, including a downgrade of our securities by or change in opinion of industry analysts and a related decline in our share price.

The terms of our current or future indebtedness may restrict our current and future operations, which would impair our ability to respond to changes in our business and to manage our business.

Our revolving credit facility and the indentures governing the 2029 Notes and the 2031 Notes contain, and any future indebtedness of ours would likely contain, a number of restrictive covenants that impose significant operating and financial restrictions on us subject to customary exceptions, including restricting our ability to:

•incur, assume or prepay debt or incur or assume liens,

•pay dividends or distributions or redeem or repurchase capital stock,

•make loans, investments or acquisitions,

•enter into sale-leaseback transactions,

•enter into new lines of business,

•complete a significant corporate transaction, such as a merger or sale of our company or its assets, and

•enter into agreements that prohibit the incurrence of liens or the payment by our subsidiaries of dividends and distributions.

Our failure to comply with the restrictions and the other terms and conditions under our revolving credit facility and the indentures governing the 2029 Notes and the 2031 Notes could result in a default, which in turn could result in the termination of the lenders’ commitments to extend further credit to us under our revolving credit facility and acceleration of a substantial portion of these borrowings before their due date. If that were to happen, we may not be able to repay all of the amounts that would become due under our indebtedness or refinance our debt, which could materially harm our business and force us to seek bankruptcy protection.

Bank failures or other events affecting financial institutions could have a material adverse effect on our business, financial condition and results of operations.

We are dependent upon various financial institutions to execute electronic funds transfer and paper check payments as part of our client payroll, tax and other money movement services. While we have contingency plans in place for isolated bank failures and outages, a systemic shutdown of the banking industry would impede our ability to process payments on behalf of our payroll, tax and other money movement services to clients and could have an adverse impact on our financial results and liquidity.

Our interest earned on funds held for clients may be impacted by changes in government regulations mandating the amount of tax withheld or timing of remittance or by political, economic or social factors.

We invest funds collected for clients but not yet remitted to applicable tax or regulatory agencies or to client employees in 2a-7 money market mutual funds and other cash equivalents. Nevertheless, such investments are subject to general market, interest rate, credit and liquidity risks. These risks may be exacerbated, individually or together, during periods of unusual financial market volatility.

We receive interest income from these invested client funds. A change in regulations either decreasing the amount of taxes to be withheld or allowing less time to remit taxes to applicable tax or regulatory agencies could adversely impact our interest income. Our failure to properly or timely remit taxes on behalf of our clients could result in fines, penalties and interest for which we could be responsible, and could material adversely affect our reputation, results of operation or financial condition.

Change in our credit ratings could adversely impact our results of operations and lower our profitability.

The Nationally Recognized Statistical Rating Organizations periodically evaluate our creditworthiness. Our credit ratings depend on our performance and can also be impacted by events beyond our control, such as macroeconomic and/or political factors of the U.S. and global economy. Failure to maintain our credit ratings could increase the cost of short-term borrowing which would lower our profitability, reduce our ability to obtain short-term borrowing periodically required by our business, and adversely impact our competitive position, results of operations, and financial condition.



TRINET	27	2025 FORM 10-K


RISK FACTORS			Table of Contents

We may require additional capital or need to restructure our existing debt to pursue our business objectives and to respond to business opportunities, challenges or unforeseen circumstances. If capital is not available to us, our business, results of operations, and financial condition may be adversely affected.

We intend to continue to make expenditures and investments to support the growth of our business and may require additional capital to pursue our business objectives and respond to business opportunities and challenges. However, additional funds may not be available or we may not be able to restructure our existing debt when we need to on terms that are acceptable to us, or at all. Volatility in the debt and equity capital markets may materially and adversely affect our ability to fund our business through public or private sales of equity securities or debt restructuring. Rising interest rates and/or instability in the banking and finance industries may reduce our access to debt capital. Our current debt agreements and any future debt financing that we secure in the future could involve restrictive covenants, which may make it more difficult for us to obtain additional capital and to pursue business opportunities. In addition, the restrictive covenants in the credit facility, the indentures governing our 2029 Notes and 2031 Notes and any additional credit facilities or debt agreements we may secure in the future may restrict us from being able to conduct our operations in a manner appropriate for our business and may restrict our growth, which could have an adverse effect on our business, financial condition, or results of operations.

We cannot assure you that we will be able to comply with any such restrictive covenants in our current or future indebtedness. In the event that we are unable to comply with these covenants in the future, we would seek an amendment or waiver of the covenants. We cannot assure you that any such waiver or amendment would be granted. In such event, we may be required to repay any or all of such borrowings, and we cannot assure you that we will be able to obtain alternative funding arrangements on commercially reasonable terms, or at all.

If we are unable to obtain adequate financing or financing on terms satisfactory to us, when we require it, our ability to continue to pursue our business objectives and to respond to business opportunities, challenges, or unforeseen circumstances could be significantly limited, and our business, results of operations, financial condition and prospects could be materially and adversely affected.

We cannot guarantee that our stock repurchase program will be fully implemented or that it will enhance long-term stockholder value.

In May 2014, our board of directors approved a stock repurchase program. From time to time, our board of directors authorizes increases to our stock repurchase program and has approved an aggregate total of $2,715 million as of December 31, 2025. The total remaining authorization for future stock repurchases under our stock repurchase program was $68 million as of December 31, 2025. We plan to use current cash and cash generated from ongoing operating activities to fund our stock repurchase program. Under the program, share repurchases may be made at our discretion from time to time in open market transactions, privately negotiated transactions, or other means. The program does not obligate us to repurchase any specific dollar amount or to acquire any specific number of shares of our outstanding stock. The timing and number of any future shares repurchased under the program will depend on a variety of factors, including stock price, trading volume, and general business and market conditions. Our board of directors will review the program periodically and may authorize adjustments of its terms, if appropriate. As a result, there can be no guarantee around the timing or volume of our share repurchases. The program could affect the price of our common stock, increase volatility and diminish our cash reserves. The program may be suspended or terminated at any time and, even if fully implemented, may not enhance long-term stockholder value. Refer to Part II, Item 5 of this Annual Report on Form 10-K for additional information.

Atairos, our largest stockholder, may have significant influence over our Company, and the ownership of capital stock, and thus the voting control, of our Company remains concentrated in our executive officers, directors and their affiliates, which limits your ability to influence corporate matters.

On February 1, 2017, an entity affiliated with Atairos Group, Inc. (together with its affiliates, “Atairos”) became our largest stockholder when it acquired the shares of TriNet common stock previously held by General Atlantic. In connection with this transaction, we appointed Michael J. Angelakis, the Chairman and CEO of Atairos, to our board of directors and agreed to nominate Mr. Angelakis or another designee of Atairos reasonably acceptable to our Nominating and Corporate Governance Committee for election at future annual meetings until Atairos’ beneficial ownership falls below 15% of our common stock. As of January 31, 2026, Atairos beneficially owned approximately 38% of our outstanding common stock, and all of our directors, executive officers and their affiliates, including Atairos, beneficially own, in the aggregate, approximately 39% of our outstanding common stock. As a result, Atairos, particularly when acting with our executive officers, directors and their affiliates, is able to exert substantial influence on all matters requiring stockholder approval, including the election of directors and approval of significant corporate transactions, such as a merger or other sale of our company or its assets. In addition, our stockholders have no assurances that Atairos’ holdings, or the holdings of our other large stockholders, in our common stock will not increase. This concentration of ownership could limit the ability of other stockholders to influence corporate matters and may have the effect of delaying or preventing a third party from acquiring control over us.

Item 1B. Unresolved Staff Comments

None.

Item 1C. Cybersecurity

Below is a discussion of our risk management and approach to governance as it relates to cyber risks. For additional information on the impact of cyber risks, refer to Part I, Item 1A. Risk Factors, of this Form 10-K, under the heading “Data Privacy and Security Risks”.

Cyber Risk Management and Strategy

Our Global Security program aims to safeguard critical assets through a risk-based approach to cybersecurity. The CSO provides leadership for the program. We employ a defense-in-depth strategy and have established a Security Risk Management Program. In that regard, we built a customized IRCF that was developed with the specific intent of keeping information assets secure and preventing technology resources from unauthorized disclosure, modification, deletion, and destruction. We have modeled our IRCF on several leading industry standards including portions of the NIST Cybersecurity Framework. The IRCF serves as an organizational model for governance and reporting and is reviewed annually.

Our Global Security Organization is responsible for the day-to-day execution of our cyber risk management strategy. This strategy has been incorporated into our overall ERM program and is thus informed by, and overseen through, our ERM program. Our ERM program facilitates identifying, prioritizing, analyzing and remediating enterprise risks, including cyber risks. Within the broader ERM framework, we established a specific program - the IRM program - organizing the governance of risks associated with information held by us. The IRM Steering Committee, of which our CSO is a member, manages the IRM program, discusses the management of cyber risks on a regular cadence and substantive updates from the IRM Steering Committee are provided to the ERM Steering Committee. Finally, through our ERM program, updates and discussion regarding our cybersecurity risk management are provided to and occur at the Risk Committee.

We provide on at least an annual basis cybersecurity awareness training to our employees. For example, our employees with network access participate in required training, covering topics such as spear phishing, social engineering and other cybersecurity threat awareness training.

To supplement our cyber risk management capabilities, we utilize certain third-party vendors. These vendors support our ability to proactively secure our network and systems, in addition to ongoing monitoring of our cyber environment. With respect to our management of cyber risks arising from third-party vendors, we utilize an internal risk assessment and monitoring program that includes the identification and ongoing review of third-party controls.

As part of our cyber risk management strategy, we established a process for identifying and assessing the material risk of cybersecurity incidents. In the event a cybersecurity incident is identified, the CIRT, which is made up of a cross-functional team, including technology, security, finance and legal professionals, acts in accordance with established processes. The CIRT convenes regular meetings to review and analyze relevant cybersecurity indicators and information. Utilizing an IRC, if it is determined that an incident needs to be reviewed for potential materiality, it is referred to our Chief Legal Officer who will engage the necessary or desirable cross functional professionals as needed in order to make a determination of materiality. We also seek to regularly update and upgrade our technology investments in an effort to further support our ability to identify and assess risks from cybersecurity incidents.

As of December 31, 2025, we are not aware of any risks from cybersecurity threats that have materially affected or are reasonably likely to materially affect us, including our business strategy, results of operations, and financial condition. We continue to invest in cyber-resilience and cyber-threat response preparedness as we anticipate ongoing risks from cybersecurity threats. Refer to the “Risk Factors” section contained in Item 1A of this Form 10-K for more information on our cybersecurity-related risks.

Cyber Risk Governance

Our Cyber Risk Management Strategy described in this Item 1C. is overseen by senior executives with experience in cybersecurity and our business operations and is ultimately overseen by the Risk Committee. Our Global Security Organization is tasked with executing this strategy through the implementation of cybersecurity policies, procedures, and strategies. In the event that a cybersecurity risk is identified, as and to the extent appropriate, the Global Security Organization manages the day-to-day response to such material risk and provides regular reports to the ERM Steering Committee, or the Risk Committee, or the Board, as appropriate. The CSO is also an advisor to the Company's Disclosure Committee, which meets quarterly.

On a quarterly basis, a meeting of the Risk Committee is convened to discuss and evaluate our management of enterprise-wide risks. Each meeting of the Risk Committee is facilitated by our Executive Director for ERM and



TRINET	29	2025 FORM 10-K


PROPERTIES, LEGAL PROCEEDINGS AND MINE SAFETY DISCLOSURES						Table of Contents

includes programmatic updates from the CSO, among other enterprise risk topics. The Risk Committee provides updates to the full Board regarding the state of the Company’s ERM program.

Cyber risks are an enterprise risk that the ERM Program monitors and thus such risks are an ongoing area of focus of the ERM Steering Committee and, as a result, the Risk Committee. On a bi-monthly basis, the ERM Steering Committee is convened and receives pertinent updates regarding our management of cyber risks, as necessary.

In addition to the regularly scheduled programmatic updates that are provided to the ERM Steering Committee and the Risk Committee, we also established a process to inform such committees of significant cybersecurity events and allow them to monitor corresponding remediation efforts. Specifically, the IRM Steering Committee, consisting of senior leaders from the security, privacy, data governance, technology, records management, and third-party risk management programs, reports to the ERM Steering Committee and has the responsibility to provide updates regarding the prevention, detection, mitigation, and remediation of significant cybersecurity threats.

The ERM Steering Committee is similarly tasked with providing relevant updates to the Risk Committee, via the ERM Program, regarding significant cybersecurity threats. Additionally, we have developed a process that is specific to the management and analysis of cybersecurity incidents. This process includes weekly and monthly updates from the CIRT along with escalation criteria that allows for significant cybersecurity threats to be reviewed for materiality on an ad hoc basis. These updates are also provided to the ERM Steering Committee and the Risk Committee as necessary.

Our CSO leads our Global Security Organization which is responsible for overseeing, assessing and monitoring the Company's cyber risk management strategy. Our CSO has over 25 years of industry experience, including serving in similar roles leading and overseeing cybersecurity programs at other companies. He holds a B.S. degree from Azusa Pacific University and an M.B.A. from the University of Southern California. Team members who support our Global Security team have relevant educational and industry experience, including holding similar positions at other large companies.

Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

Market Information and Holders of Record

Our common stock is traded on the New York Stock Exchange under the symbol “TNET”.

As of February 5, 2026, we had 62 holders of record of our common stock per Computershare Trust Company N.A., our transfer agent. Our actual number of stockholders is greater than the number of our record holders, because it includes stockholders who are beneficial owners of our common stock, but whose shares are held in street name by brokers and other nominees. This number of holders of record also does not include stockholders whose shares may be held in a trust by other entities.

For information regarding our equity-based incentive plans, please refer to Part III, Item 12. Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters, of this Form 10-K.

Dividend Policy

The decision to pay cash dividends in the future is made at the discretion of our board of directors and will depend on then-existing conditions, including our financial condition, operating results, contractual restrictions under our revolving credit facility (refer to Note 8 in Part II, Item 8. Financial Statements and Supplementary Data, of this Form 10-K), capital requirements, business prospects and other factors our board of directors may deem relevant.

In 2025 and 2024, we declared dividends on common stock on a quarterly basis of $0.275 and $0.25 per share, respectively, with payments at those rates beginning in April of each year. While we have historically paid dividends to holders of our common stock on a quarterly basis, the declaration and payment of future dividends will depend on many factors, including, but not limited to, our earnings, financial condition, business development needs and regulatory considerations, and are at the discretion of our Board.

Performance Graph

The following graph compares the cumulative total return on our common stock since December 31, 2020 with the cumulative total return on the S&P 500 Index and a Peer Group Index. The cumulative total return is based on the assumption that $100 had been invested in TriNet Group, Inc. common stock, the Standard & Poor’s 500 Stock Index (S&P 500) and common stock of members of a Peer Group Index, all on December 31, 2020 and that all dividends were reinvested. The cumulative dollar total returns shown on the graph represent the value that such investments would have had at each year end.

(1) In May 2014, our board of directors approved a stock repurchase program pursuant to which we are authorized to repurchase our common stock in privately negotiated and/or open market transactions, including under plans complying with Rule 10b5-1 under the Securities Exchange Act of 1934. From time to time, our board of directors authorizes increases to our stock repurchase program and has approved an aggregate total of $2,715 million as of December 31, 2025. The total remaining authorization for future stock repurchases under our stock repurchase program was $68 million as of December 31, 2025. The program does not have an expiration date.

(2) Includes shares surrendered by employees to us to satisfy tax withholding obligations that arose upon vesting of restricted stock units granted pursuant to approved plans.

(3) We repurchased a total of approximately $61 million of our outstanding stock during the three months ended December 31, 2025.

We use our stock repurchase program to return value to our stockholders and to offset dilution from the issuance of stock under our equity-based incentive plans and employee purchase plan. As part of our stock repurchase program, we repurchased approximately $182 million of our common stock in 2025. We plan to use current cash and cash generated from ongoing operating activities to fund our stock repurchase program.

Our stock repurchases are subject to certain restrictions under the terms of our revolving credit facility. For more information about our stock repurchases and the restrictions imposed by our revolving credit facility, refer to Note 8 and Note 11 in Part II, Item 8.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Operational Highlights

Our consolidated results for 2025 reflect our continuing efforts to serve our clients, attract new clients and invest in our platform.

During 2025 we:

•made progress on our medium-term strategy focusing our business on our core value proposition, improving the efficiency and effectiveness of our operations, which has helped us realize all time high net promoter scores,

•continued to grow our ASO services product and completed the sale of TriNet Clarus R+D,

•achieved significant repricing of our insurance services rates in light of rising insurance costs,

•made progress in growing our sales force and broker channel partnerships,

•demonstrated disciplined expense management in line with our expectations,

•opened our new corporate center in Atlanta and made significant progress building out our India operations, and

•paid common stock dividends of $0.25 per share in January and $0.275 per share in April, July, and October. Together with common stock repurchases of $182 million, we returned $235 million to stockholders.

Performance Highlights

Our results for 2025 when compared to 2024 are noted below:


$5.0B			$217M			91%
Total revenues			Income before tax			Insurance cost ratio
(1)	%	decrease	(4)	%	decrease	1	%	increase

	Average WSE			Total WSE
	(5)	%	decrease	(10)	%	decrease
*	Non-GAAP measure. See definitions below under the heading "Non-GAAP Financial Measures".

Our total revenues decreased 1%, primarily driven by lower co-employed Average WSEs partially offset by higher rates charged for our services. Average WSEs and Total WSEs decreased 5% and 10%, respectively, compared to the same period in 2024, primarily due to WSE decreases in our Technology, Professional Services, and Main Street verticals, which were partially attributable to repricing of our health benefits services.

Our results are highly influenced by health care cost and utilization trends. Our ICR was 1 percent higher compared to the same period in 2024, driven by insurance costs outpacing the growth in insurance services revenues.

Higher insurance costs and lower revenues, resulted in decreases of net income and Adjusted Net income of 10% and 14%, respectively, as compared to the same period in 2024.

Non-GAAP Financial Measures

In addition to financial measures presented in accordance with 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, - interest expense, bank fees and other, - depreciation, - amortization of intangible assets, - stock based compensation expense, - amortization of cloud computing arrangements, - transaction and integration costs, and - restructuring 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, 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, 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.

(1) Non-GAAP effective tax rate is 25.0% for 2025, and 25.6% for 2024, which excludes the income tax impact from stock-based compensation, changes in uncertain tax positions, and nonrecurring benefits or expenses from federal legislative changes.

Operating Metrics

Worksite Employees (WSE)

Average WSE change is a volume measure we use to monitor the performance of our PEO business. Our PEO clients generally change their payroll service providers at the beginning of the payroll tax and benefits enrollment year; as a result, we have historically experienced our highest volumes of new PEO clients joining and existing clients terminating in the month of January. PEO client attrition, new PEO client additions and changes in employment levels within our installed PEO client base all impact our Average WSEs and Total WSEs as we move through a calendar year.

We support WSEs from the date on which their co-employment with TriNet commences through the end of their co-employment with TriNet and also after their co-employment period. We define WSEs to include co-employees and other individuals receiving PEO services, such as individuals who receive COBRA benefits or are subject to partnership tax reporting as well as individuals who utilize our PEO platform on behalf of TriNet PEO clients.

We charge a platform user access fee to clients for those users of our PEO platform that may not be co-employed by us as well as for co-employees for whom payroll may not be regularly run. In addition to co-employees for whom payroll may not be regularly run, such as partners in a partnership, this group of users also includes individuals authorized by our clients to access and use the PEO platform for functions such as bookkeeping and benefits management. We refer to these users as PEO Platform Users. Starting in 2023 and rolled out through 2024, we began billing clients in groups over time, driving a large increase in PEO Platform Users over that period.

The effect of this fee is that we receive revenue from two types of users on our PEO platform, those that are co-employed in our PEO business and those that are utilizing our PEO platform, albeit in a more limited capacity. The table below illustrates how those two components comprise our Total WSE and Average WSE metrics.


	Year Ended December 31,			% Change
	2025	2024	2023	2025 vs. 2024	2024 vs. 2023

Average WSEs	333,886	352,681	331,423	(5)	6
Co-Employed	304,985	332,456	330,423	(8)	1
PEO Platform Users	28,901	20,225	1,000	43	1,923
Total WSEs	323,206	360,681	347,542	(10)	4
Co-Employed	294,025	330,104	335,543	(11)	(2)
PEO Platform Users	29,181	30,577	11,999	(5)	155

Average WSEs decreased 5% when comparing 2025 to 2024, driven by client attrition outpacing new client additions partially offset by limited hiring in our installed base over the past twelve months. These declines were primarily in our Technology, Professional Services, and Main Street verticals.

Total WSEs can be used to estimate our beginning WSEs for the next period and, as a result, can be used as an indicator of our potential future revenue growth, business growth, and client retention. Total WSEs decreased 10% when compared to the same period in 2024, primarily due to declines in our Technology, Professional Services, and Main Street verticals. This was partially attributable to necessary repricing of our health benefits services.

Anticipated revenues for future periods can diverge from the revenue expectation derived from Average WSEs or Total WSEs due to pricing differences across our HCM solutions and services and the degree to which clients and WSEs elect to participate in our solutions during future periods. In addition to focusing on growing our Average WSE and Total WSE counts, we also focus on pricing strategies, benefit participation and service differentiation to expand the value we provide to our clients and our resulting revenue opportunities. We report the impact of client and WSE participation differences as a change in mix.

We continue to invest in efforts intended to enhance client experience, improve our new sales performance, and manage client attrition, through product development as well as operational and process improvements. In addition to focusing on retaining and growing our WSE base, we continue to review acquisition or other opportunities to expand our product offering and provide further scale.

MANAGEMENT'S DISCUSSION AND ANALYSIS			Table of Contents

The following graphs show our quarterly average WSEs and Total WSEs since the first quarter of 2024.

Insurance Cost Ratio (ICR)

ICR is a performance measure calculated as the ratio of insurance costs to insurance service revenues. We believe that ICR promotes an understanding of our insurance cost trends and our ability to align our relative pricing to risk performance.

We purchase workers' compensation and health benefits coverage for our WSEs. Under the insurance policies for this coverage, we bear claims costs up to a defined deductible amount. Our insurance costs, which comprise a significant portion of our overall costs, are significantly affected by our WSEs’ health and workers' compensation insurance claims experience. We set our insurance service fees for workers’ compensation and health benefits in advance for fixed benefit periods. As a result, any increases in insurance costs above our projections, will be reflected as a higher ICR, and result in lower net income. Any decreases in insurance costs below our projections, will be reflected as a lower ICR and result in higher net income.

Under our fully-insured workers' compensation insurance policies, we assume the risk for losses up to $1 million per claim occurrence (deductible layer). The ultimate cost of the workers’ compensation services provided cannot be known until all the claims are settled. Our ability to predict these costs is limited by unexpected increases in frequency or severity of claims, which can vary due to changes in the cost of treatments or claim settlements.

Under our risk-based health insurance policies, we assume some of the risk of variability in future health claims costs for our enrollees. This variability typically results from changing trends in the volume, severity and ultimate cost of medical and pharmaceutical claims, due to changes to the components of medical cost trend, which we define as changes in participant use of services, including the introduction of new treatment options, changes in treatment guidelines and mandates, and changes in the mix, cost of providing treatment and timing of services provided to plan participants. These trends change, and other seasonal trends and variability may develop. As a result, it is difficult for us to predict our insurance costs with accuracy and a significant increase in these costs could have a material adverse effect on our business.



(in millions)	2025			2024			2023
Insurance costs	$	3,835		$	3,797		$	3,513
Insurance service revenues	4,224			4,224			4,166
Insurance Cost Ratio	91		%	90		%	84		%

ICR increased for the year ended December 31, 2025 as compared to 2024, primarily driven by higher health benefits insurance costs that rose at a higher rate than our insurance services revenues for health benefits. The increase in insurance costs was primarily due to higher rates paid for outpatient and professional services, as well as pharmacy costs for increased utilization of specialty drugs and other high-cost prescriptions, particularly medications for diabetes and obesity. This increase was partially offset by lower volume.

Total Revenues

Our revenues consist of PSR, ISR and interest income. PSR represents fees charged to clients for processing payroll-related transactions on behalf of our PEO and ASO clients, access to our HR expertise and technology, employment and benefit law compliance services, other HR-related and tax credit filing services and fees charged to access our cloud-based ASO services. ISR consists of insurance-related billings and administrative fees collected from PEO clients and withheld from WSEs for workers' compensation insurance and health benefit insurance plans provided by third-party insurance carriers.

Monthly revenues per co-employed Average WSE is a measure we use to monitor our PEO pricing strategies. This measure increased 8% in 2025 compared to 2024.

We also use the following measures to further analyze changes in total revenue:

•Volume - the percentage change in period over period co-employed Average WSEs,

•Rate - the combined weighted average percentage changes in service fees for each vertical service and changes in service fees associated with each insurance service offering,

•Mix - the change in composition of co-employed Average WSEs within our verticals combined with the composition of our enrolled co-employed WSEs within our insurance service offerings and the composition of products and services our clients receive, such as PEO Platform Users,

•HRIS and ASO, and

•Interest income.

Total revenue decreased slightly for the year ended December 31, 2025, as lower co-employed Average WSEs was partially offset by rate increases for both professional services and insurance services revenues.



TRINET	39	2025 FORM 10-K


MANAGEMENT'S DISCUSSION AND ANALYSIS			Table of Contents

PSR

Our PEO and ASO clients are primarily billed on a fee per WSE or ASO User per month per transaction. Our vertical approach provides us the flexibility to offer our PEO clients in different industries with varied services at different prices, which we believe potentially reduces the value of solely using Average WSE and Total WSE counts as indicators of future potential revenue performance.

During 2025, we began migrating our clients from our predecessor HRIS services to our ASO product. PSR from PEO Services customers and HRIS and ASO services clients was as follows:



(in millions)	2025		2024
PEO Services	$	684	$	723
HRIS and ASO Services	35		42
Total	$	719	$	765

We also analyze changes in PSR with the following measures:

•Volume - the percentage change in period over period co-employed Average WSEs,

•Rate - the weighted average percentage change in fees for each vertical,

•Mix - the change in composition of co-employed Average WSEs across our verticals and the composition of products and services our clients receive, including PEO Platform Users, and

•HRIS and ASO.

The decrease in PSR for the year ended December 31, 2025 was primarily driven by lower co-employed Average WSEs, and the discontinuance of both a client-level technology fee and our Clarus R+D product. PSR from HRIS services has decreased as we continue to wind down this product and migrate clients to our ASO services.

ISR

ISR consists of insurance services-related billings and administrative fees collected from PEO clients and withheld from WSE payroll for health benefits and workers' compensation insurance provided by third-party insurance carriers.



TRINET	40	2025 FORM 10-K


MANAGEMENT'S DISCUSSION AND ANALYSIS			Table of Contents

We use the following measures to analyze changes in ISR:

•Volume - the percentage change in period over period co-employed Average WSEs,

•Rate - the weighted average percentage change in fees associated with each of our insurance service offerings, and

•Mix - all other changes including the composition of our enrolled co-employed WSEs within our insurance service offerings (health plan enrollment).

ISR was flat for the year as rate increases were offset by lower co-employed Average WSEs.

Interest Income

Interest income primarily includes interest income earned from cash held for our PEO and ASO clients as a result of the requirement of our clients to prefund their payroll and related taxes and other withholding liabilities before payroll is processed or due for payment. Interest income also includes our portion of interest received from tax jurisdictions related to payroll and other tax refunds. Interest income from tax refunds is recognized when the amount and timing of the interest become determinable.

Interest income was slightly higher than the prior period as higher interest received related to payroll tax refunds was partially offset by a decrease in interest earned on our cash and investments.

Insurance Costs

Insurance costs include insurance premiums for coverage provided by insurance carriers, payments for claims costs and expenses for other risk management and administrative services, reimbursement of claims payments made by insurance carriers or third-party administrators below a predefined deductible limit, and changes in accrued costs related to contractual obligations with our workers' compensation and health benefit carriers.

We use the following measures to analyze changes in insurance costs:

•Volume - the percentage change in period over period co-employed Average WSEs,



TRINET	41	2025 FORM 10-K


MANAGEMENT'S DISCUSSION AND ANALYSIS			Table of Contents

•Rate - the weighted average percentage change in cost trend associated with each of our insurance service offerings, and

•Mix - all other changes including the composition of our enrolled co-employed WSEs within our insurance service offerings (health plan enrollment).

The slight increase in insurance costs for the year was primarily due to higher rates paid for outpatient and professional services and increased utilization of high-cost drugs, particularly for specialty drugs and non-specialty medications for diabetes and obesity. This increase is partially offset by lower co-employed Average WSEs.

Expenses

Expenses include COPS, S&M, G&A, SD&P, D&A, collectively referred to as OE, as well as IE.

We had approximately 3,400 colleagues as of December 31, 2025 primarily across the U.S. but also in India and Canada, down approximately 200 colleagues from 2024. Compensation costs for our colleagues include payroll, payroll taxes, SBC, bonuses, commissions and other payroll- and benefits-related costs. Compensation-related expenses represented 66% and 63% of our expenses in 2025 and 2024, respectively.

In 2025, we had an expense decrease of 7% compared to 2024. This decrease was driven largely by lower expenses related to the execution of our medium term strategy, which includes process optimization, further development of our product offerings, and go-to-market innovations compared to the higher asset impairment and severance expenses seen in 2024 as a result of the initial implementation of such strategy. The ratio of expenses to total revenues was 19% and 20% in 2025 and 2024, respectively.

Income Taxes

Our ETR was 29% and 23% for 2025 and 2024, respectively. The increase in the rate was primarily attributable to decreases in tax benefits for stock-based compensation and charges to valuation allowances.

On July 4, 2025, H.R. 1 - One Big Beautiful Bill Act (“OBBBA”) was signed into law, which includes significant changes to federal tax law and other regulatory provisions that may impact the Company. ASC 740, “Income Taxes”, requires the effects of changes in tax rates and laws on deferred tax balances to be recognized in the period in which the legislation is enacted. OBBBA did not have a material impact on our ETR.

Liquidity and Capital Resources

Liquidity

Liquidity is a measure of our ability to access sufficient cash flows to meet the short-term and long-term cash requirements of our business operations. Our principal source of liquidity for operations is derived from cash provided by operating activities. We rely on cash provided by operating activities to meet our short-term liquidity requirements, which primarily relate to the payment of corporate payroll and other operating costs, and capital expenditures. Our cash flow related to WSE payroll and benefits is generally matched by advance collection from our PEO clients. To minimize the credit risk associated with remitting the payroll and associated taxes and benefits costs, we require PEO clients to prefund the payroll and related payroll taxes and benefits costs.

Included in our balance sheets are assets and liabilities resulting from transactions directly or indirectly associated with WSEs, including payroll and related taxes and withholdings, our sponsored workers' compensation and health insurance programs, and other benefit programs. Although we are not subject to regulatory restrictions that require us to do so, we distinguish our corporate assets and liabilities separately from those current assets and liabilities held by us to satisfy our employer obligations associated with our WSEs.

TriNet Trust, which is consolidated into our financial statements, holds funds provided by ASO clients for the remittance to ASO Users, tax authorities and other recipients. TriNet Trust also holds ownership and responsibility of certain bank accounts that hold ASO client funds. The associated cash is reflected on our consolidated balance sheets as restricted cash and the associated liabilities are classified as accrued wages, payroll tax liabilities and other payroll withholdings, and accounts payable and other current liabilities. As of December 31, 2025, the balance of restricted cash in TriNet Trust was $79 million. We include the assets and liabilities related to the TriNet Trust in the "WSE & TriNet Trust" category because the underlying cash flows of TriNet Trust are related to the same type of payroll and payroll related liabilities as our WSE cash flows. We continue to use this trust structure as we transition our HRIS services to ASO services.

MANAGEMENT'S DISCUSSION AND ANALYSIS			Table of Contents

Working capital for WSEs and TriNet Trust related activities

We designate funds to ensure that we have adequate current assets to satisfy our current obligations associated with WSEs. We manage our WSE payroll and benefits obligations through collections of payments from our clients which generally occur two to three days in advance of client payroll dates. We regularly review our short-term obligations associated with our WSEs (such as payroll and related taxes, insurance premium and claim payments) and designate funds required to fulfill these short-term obligations, which we refer to as PFC. PFC is included in current assets as restricted cash, cash equivalents and investments.

We manage our sponsored benefit and workers' compensation insurance obligations by maintaining collateral funds in restricted cash, cash equivalents and investments. These collateral amounts are generally determined at the beginning of each plan year and we may be required by our insurance carriers to adjust our collateral balances when facts and circumstances change. We regularly review our collateral balances with our insurance carriers and anticipate funding further collateral in the future based upon our capital requirements. We classify our restricted cash, cash equivalents and investments as current and noncurrent assets to match against the anticipated timing of payments to carriers.

The following table summarizes our workers' compensation obligations, gross of collateral, as of December 31, 2025,


	Payments Due by Period
(in millions)	Total		Less than 1 year		1-3 years		3-5 years		More than 5 years
Workers' compensation obligations (1)	$	151	$	43	$	46	$	19	$	43

(1) Represents estimated payments that are expected to be made to carriers for various workers' compensation programs under the contractual obligations. These obligations include the costs of reimbursing the carriers for paying claims within the deductible layer in accordance with the workers' compensation insurance policy.

Because the liabilities of the TriNet Trust are largely driven by how much in cash has been deposited into the trust, there is generally no significant working capital in that entity.

Working capital for corporate purposes

Corporate working capital as of December 31, 2025 increased $32 million from December 31, 2024, primarily due to the decreases in our corporate current liabilities. The decrease in corporate current liabilities is primarily driven by the repayment of the outstanding balance on our revolving credit facility in the third quarter of 2025, leaving no outstanding balance on our $700 million revolving line of credit.

We use our available cash and cash equivalents to satisfy our operational and regulatory requirements and to fund capital expenditures. We believe that we can meet our present and reasonably foreseeable operating cash needs and future commitments through existing liquid assets, continuing cash flows from corporate operating activities and the potential issuance of debt or equity securities. We hold both corporate cash and cash associated with WSEs across multiple financial institutions to reduce concentrations of counterparty risk. We believe our existing corporate cash and cash equivalents and positive working capital will be sufficient to meet our working capital expenditure needs for at least the next twelve months.

Investments

We invest a portion of available cash in investment-grade securities with effective maturities less than five years that are classified on our balance sheets as investments. We consider industry and issuer concentrations in our investment policy.

We also invest funds held as collateral to satisfy our long-term obligation towards workers' compensation liabilities. These investments are classified on our balance sheets as restricted cash, cash equivalents and investments. We review the amount and the anticipated holding period of these investments regularly in conjunction with our estimated long-term workers' compensation liabilities and anticipated claims payment trend. At December 31, 2025, our investments had a weighted average duration of three-year and an average S&P credit rating of AA.

As of December 31, 2025, we held approximately $2.1 billion in restricted and unrestricted cash, cash equivalents and investments, of which $287 million was unrestricted cash and cash equivalents. Refer to Note 2 in Part II, Item 8. Financial Statements and Supplemental Data, in this Form 10-K for a summary of these funds.

Capital Expenditures

During the twelve months ended December 31, 2025 and 2024, we continued to make investments in software and hardware as we enhanced our existing service offerings and technology platform. We expect capital investments in our software and hardware to continue in the future.

Financing Activities

Net cash used in financing activities for the years ended December 31, 2025 and 2024, which consisted of WSE and TriNet Trust related activities and our debt and equity-related activities are presented below.

The year-over-year change in net cash used in financing activities for WSE and TriNet Trust purposes was primarily driven by timing of client payments, payments of payroll and payroll taxes and insurance claim activities.

During the year ended December 31, 2025, we repurchased 2,755,287 shares of our common stock for approximately $182 million through our existing stock repurchase program in addition to 68,823 shares acquired to satisfy tax withholding obligations related to SBC vesting. As of December 31, 2025, approximately $68 million remained available for repurchase under all authorizations by our Board. In February 2026, our Board authorized a $336 million incremental increase to our stock repurchase program. Repurchases are to be deployed subject to market conditions. We plan to use current cash and cash generated from ongoing operating activities to fund this stock repurchase program.

We paid common stock dividends of $0.25 per share in January 2025 and $0.275 per share in April, July and October 2025. We also declared a common stock dividend of $0.275 per share which was paid in January 2026.

Capital Resources

As of December 31, 2025, $500 million and $400 million aggregate principal of our 2029 Notes and 2031 Notes was outstanding, respectively. The indenture governing our 2029 Notes and 2031 Notes each includes restrictive covenants limiting our ability to: (i) create liens on certain assets to secure debt; (ii) grant a subsidiary guarantee of certain debt without also providing a guarantee of the 2029 Notes or 2031 Notes, as applicable; and (iii) consolidate or merge with or into, or sell or otherwise dispose of all or substantially all of our assets to, another person, subject, in each case, to certain customary exceptions.

Our 2021 Credit Agreement includes a $700 million revolver. In July 2025, we paid off the remaining outstanding balance and as of December 31, 2025, no outstanding balance remained. The 2021 Credit Agreement includes negative covenants that limit our ability to incur indebtedness and liens, sell assets and make restricted payments, including dividends and investments, subject to certain exceptions. In addition, the 2021 Credit Agreement also contains other customary affirmative and negative covenants and customary events of default. The 2021 Credit Agreement also contains a financial covenant that requires the Company to maintain certain maximum total net leverage ratios.

We were in compliance with all financial covenants under our 2021 Credit Agreement, 2029 Notes and 2031 Notes at December 31, 2025.

MANAGEMENT'S DISCUSSION AND ANALYSIS			Table of Contents

Critical Accounting Judgments and Estimates

Our consolidated financial statements are prepared in accordance with GAAP, which require us to make estimates, judgments, and assumptions that affect reported amounts of assets, liabilities, revenues and expenses, and the related disclosures of contingent assets and liabilities. These estimates are based on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Some of the assumptions are highly uncertain at the time of estimation. To the extent actual experience differs from the assumptions used, our consolidated financial statements could be materially affected. For additional information about our accounting policies, refer to Note 1 in Part II, Item 8. Financial Statements and Supplementary Data, of this Form 10-K.

The following items require significant estimation or judgment:

Insurance Costs

We purchase workers' compensation and health benefits coverage for our colleagues and WSEs. As part of these insurance policies, we bear claims costs up to a defined deductible amount and as a result, we establish accrued insurance costs including both known claims filed and estimates for incurred but not reported claims.

We use qualified actuaries to evaluate, review and recommend estimates of our accrued workers' compensation and health insurance costs. The accrued costs studies performed by these qualified actuaries analyze historical claims data to develop a range of our potential ultimate costs using loss development, expected loss ratio and frequency/severity methods in accordance with Actuarial Standards of Practice. These methods are applied to classes of the claims data organized by policy year and risk class.

Key judgments and evaluations in arriving at loss estimates by class and the accrued costs selection overall include:

•the selection of method used and the relative weights given to selecting the method used for each policy year,

•the underlying assumptions of LDF used in these models,

•the effect of any changes to the insurers' claims handling and payment processes,

•evaluation of medical and indemnity cost trends, costs from changes in the risk exposure being evaluated and any applicable changes in legal, regulatory or judicial environment.

We review and evaluate these judgments and the associated recommendations in concluding the adequacy of accrued costs. Our quarterly reserving process involves the collaboration of our internal qualified actuaries and our actuarial and finance departments to approve a single point best estimate. In selecting this best estimate, management considers the actuarial estimates and applies informed judgment regarding qualitative factors that may not be fully captured in these actuarial estimates. Such factors include but are not limited to: the timing, volume, severity and complexity of claims, social and judicial trends, medical treatment trends, the extent of our historical loss data versus industry information, rates of participant turnover, the impact of MCT and seasonal trends, the impact of setting prices in advance of benefit periods, and the impact of unanticipated events. Where adjustments are necessary these are recorded in the period in which the adjustments are identified.

These accrued costs may vary in subsequent quarters from the amount estimated. Certain assumptions used in estimating these accrued costs are highly judgmental. Our accrued costs, results of operations and financial condition can be materially impacted if actual experience differs from the assumptions used in establishing these accrued costs.

Accrued Workers' Compensation Costs

Under our policies, we are responsible for reimbursing the insurance carriers for workers' compensation losses up to $1 million per claim occurrence (Deductible Layer). As workers' compensation costs for a particular period are not known for many years after the losses have occurred, these costs represent our best estimate of unpaid claim losses and loss adjustment expenses within the Deductible Layer in accordance with our insurance policies. We use actuaries to evaluate, review and recommend accrued workers' compensation costs on a quarterly basis. The data is segmented by class and state and analyzed by policy year, and states where we have small exposure are aggregated into a single grouping.



TRINET	49	2025 FORM 10-K


MANAGEMENT'S DISCUSSION AND ANALYSIS			Table of Contents

We use a combination of loss development, expected loss ratio and frequency/severity methods which include the following inputs, assumptions and analytical techniques:

•historical volume and severity of workers' compensation cost experience, exposure data and industry loss experience related to TriNet’s insurance policies,

•inputs of WSEs’ job responsibilities and location,

•estimates of future cost trends,

•expected loss ratios for the latest accident year or prior accident years, adjusted for the loss trend, the effect of rate changes and other quantifiable factors, and

•LDFs to project the reported losses for each accident year to an ultimate basis.

Final cost settlements may vary materially from the present estimates, particularly when payments do not occur until well into the future. In our experience, plan years related to workers' compensation programs may take 10 years or more to be fully settled.

We believe that our estimate of accrued workers' compensation costs is most sensitive to LDFs given the long reporting and paid development patterns for our workers' compensation loss costs. Our methods of estimating accrued workers' compensation costs rely on these LDFs and an estimate of future cost trend.

The following table illustrates the sensitivity of changes in the LDFs on our year end estimate of insurance costs (in millions of dollars):


Change in loss development factor			Change in insurance costs
-5.0%			($30)
-2.5%			($17)
+2.5%			$18
+5.0%			$35

Accrued Health Insurance Costs

We sponsor and administer a number of employee benefit plans for our WSEs, including group health, dental, vision and life insurance as an employer plan sponsor under section 3(5) of the ERISA. Approximately 88% of our group health insurance costs relate to risk-based plans in which we agree to reimburse our carriers for any claims paid within an agreed-upon per-person deductible layer up to a maximum aggregate exposure limit per policy. These deductible dollar limits and maximum limits vary by carrier and year.

Costs covered by these insurance plans generally develop on average within three to six months so insurance costs and accrued health insurance costs include estimates of claims IBNP. Data is grouped and analyzed by insurance carrier.

To estimate accrued health benefits costs we use a number of inputs, assumptions and analytical techniques:

•historical loss claims payment patterns and MCT rates related to TriNet’s insurance policies,

•current period claims costs and claims reporting patterns (completion factors), and

•plan enrollment.

MCT rates are a significant factor we use in developing our accrued health insurance costs. MCT are developed through an analysis of claims incurred in prior months, provider pricing and indicators of health care utilization, including pharmacy utilization trends, and outpatient and inpatient utilization. Many factors may cause MCT to vary from our estimates. Such factors include, but are not limited to: the timing of the emergence of claims, volume, severity and complexity of claims, social and judicial trends, medical treatment trends, the extent of our historical loss data versus industry information, rates of participant turnover, the impact of MCT and seasonal trends, the impact of setting prices in advance of benefit periods, new treatment options, and the impact of unanticipated events.

MANAGEMENT'S DISCUSSION AND ANALYSIS			Table of Contents

The following table illustrates the sensitivity of changes in the MCT on our year end estimate of insurance costs (in millions of dollars):


Change in medical cost trend			Change in insurance costs

+2.0%			$15
+1.0%			$8
-1.0%			$(8)
-2.0%			$(15)
-3.0%			$(23)

Completion factors are an actuarial estimate based on historical experience and analysis of current trends, of paid costs to carriers as a percentage of the expected ultimate costs to carriers. Many factors may cause actual claims submissions rates from our carriers to vary from our estimated completion factors, including carrier claims processing patterns, the mix of providers and the mix of electronic versus manual claims submitted to our carriers.

The following table illustrates the sensitivity of changes in completion factors on our year end estimate of insurance costs (in millions of dollars):


Change in completion factors			Change in insurance costs

QUANTITATIVE AND QUALITATIVE DISCLOSURES			Table of Contents

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

We are exposed to market risks in connection with our business, which primarily relate to fluctuations in interest rates. Our exposure to changes in interest rates relates primarily to our investment portfolio and outstanding borrowings under our floating rate 2021 Revolver. Changes in interest rates affect the interest earned on the Company's cash, cash equivalents and the fair value of our investments as well as the cost of borrowing under our 2021 Revolver.

Our cash equivalents consist primarily of money market mutual funds, which are not significantly exposed to interest rate risk. Our investments are subject to interest rate risk because these securities generally include a fixed interest rate. As a result, the market values of these securities are affected by changes in prevailing interest rates. We attempt to limit our exposure to interest rate risk and credit risk by investing in instruments that meet the minimum credit quality, liquidity, diversification and other requirements of our investment policy. Our investments consist of liquid, investment-grade securities. The risk of interest rate changes on investment balances was not material at December 31, 2025 and 2024.

In February 2021, we issued $500 million aggregate principal of 3.50% senior unsecured notes maturing in March 2029 (our 2029 Notes) and in August 2023, we issued $400 million aggregate principal of 7.125% senior unsecured notes maturing in August 2031 (our 2031 Notes). Our 2029 Notes and 2031 Notes are carried at their cost, net of issuance costs. Since our 2029 Notes and 2031 Notes bear interest at fixed rates, we have no financial statement risk associated with changes in interest rates related to our outstanding notes. However, the fair value of our 2029 Notes and our 2031 Notes fluctuates when interest rates change.

Our 2021 Credit Agreement includes a $700 million revolving credit facility. As of December 31, 2025, we had no outstanding borrowings under this facility.

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.



TRINET	54	2025 FORM 10-K


FINANCIAL STATEMENTS			Table of Contents

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.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

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

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of TriNet Group, Inc. and subsidiaries (the "Company”) 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 (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control - Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2025, of the Company and our report dated February 12, 2026, expressed an unqualified opinion on those financial statements.

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.

TRINET GROUP, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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 ASO 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 ASO 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 in one 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

Our consolidated financial statements are prepared in conformity with generally accepted accounting principles in the United States of America (GAAP). All intercompany accounts and transactions have been eliminated in consolidation. Certain prior year amounts within operating activities of the Consolidated Statement of Cash Flows 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 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 TriNet Trust for the purpose of holding ASO clients' payroll funds for the remittance to ASO Users, tax authorities and other recipients. TriNet Trust's assets are restricted and can only be used for payments on behalf of ASO clients, 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 ASO client funds and assumed related liabilities.

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 consolidated financial statements could be materially affected.

Revenue Recognition

Revenues are recognized when the promised services are transferred to our clients, in an amount that reflects the consideration that we expect to receive in exchange for services. We generate all of our revenue from contracts with clients. We disaggregate revenues into professional services revenues and insurance services revenues as reported on the consolidated statements of income and comprehensive income. In the majority of our contracts, both the client and the Company may terminate the contract without penalty by providing a 30-day notice.

Performance Obligations

At contract inception, we assess the services promised in our contracts with clients and identify a performance obligation for each distinct promise to transfer to the client a service or bundle of services. We determined that the following distinct services represent separate performance obligations:

•Payroll and payroll tax processing,

•Health benefits services, and

•Workers’ compensation services

Payroll and payroll tax processing performance obligations include services to process payroll and payroll tax-related transactions on behalf of our PEO and ASO clients. Revenues associated with this performance obligation are reported as professional service revenues and recognized using an output method in which the promised services are transferred when a client's payroll is processed by us and WSEs and users are paid. Professional service revenues are stated net of the gross payroll and payroll tax amounts funded by our clients. Although we assume the responsibilities to process and remit the payroll and payroll related obligations, we do not assume employment-related responsibilities such as determining the amount of the payroll and related payroll obligations. As a result, we are the agent in this arrangement for revenue recognition purposes.



TRINET	62	2025 FORM 10-K


FINANCIAL STATEMENTS			Table of Contents

Health benefits and workers' compensation services include performance obligations to provide TriNet-sponsored health benefits and workers' compensation insurance coverage through insurance policies provided by third-party insurance carriers and settle deductible amounts on those policies. Revenues associated with these performance obligations are reported as insurance services revenues and are recognized using the output method over the period of time that the client and WSEs are covered under TriNet-sponsored insurance policies. We control the selection of health benefits and workers' compensation coverage made available. As a result, we are the principal in this arrangement for revenue recognition purposes and insurance services revenues are reported gross.

We generally charge new clients a nominal upfront non-refundable fee to recover our costs to set them up on our TriNet platform for payroll processing and other administrative services, such as benefit enrollments. These fees are accounted for as part of our transaction price and are allocated among the performance obligations based on their relative standalone selling prices.

Client Deposits and Other Client Liabilities

Client deposits and other client liabilities represent our contractual commitments and payables to clients, including indemnity guarantee payments received from clients, amounts prefunded by clients for their payroll and related taxes and other withholding liabilities before payroll is processed or due for payment, as well as service fee consideration received for unsatisfied performance obligations.

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.

Interest Income

We recognize interest income on cash and investments as revenue because the collection and processing of funds held for the benefit of our clients are critical components of providing these services and the associated interest we earn is a core part of our operations. Interest income is recognized when earned. Our portion of any interest income received from tax jurisdictions related to tax refunds is recognized when the timing and amounts of the interest are determinable.

Payroll Funds Receivable

For our PEO clients, we recognize WSE payroll and payroll tax liabilities in the period in which the WSEs perform work. When clients' pay periods cross reporting periods, we accrue the portion of the unpaid WSE payroll where we assume, under state regulations, the obligation for the payment of wages and the corresponding payroll tax liabilities associated with the work performed prior to period-end. These estimated payroll and payroll tax liabilities



TRINET	63	2025 FORM 10-K


FINANCIAL STATEMENTS			Table of Contents

are recorded in accrued wages. The associated receivables to pay those wages, including estimated revenues, offset by advance collections from clients and an allowance for credit losses, are recorded as payroll funds receivable. As of December 31, 2025 and 2024, advance collections included in payroll funds receivable were $221 million and $171 million, respectively.

Contract Costs

We recognize as deferred commission expense the incremental cost to obtain a contract with a client for certain components under our commission plans for sales representatives that are directly related to new clients onboarded as we expect to recover these costs through future service fees. Such assets are amortized over the estimated average client tenure. These commissions are earned on the basis of the revenue generated from payroll and payroll tax processing performance obligations. When the commission on a renewal contract is not commensurate with the commission on the initial contract, any incremental commission will be capitalized and amortized over the estimated average client tenure. If the commission for both the initial contract and renewal contracts are commensurate, such commissions are expensed in the contract period. The below table summarizes the amounts capitalized and amortized during the years ended December 31, 2025, 2024 and 2023:


	Year Ended December 31,
(in millions)	2025		2024		2023
Deferred commission expense:
Capitalized	$	25	$	38	$	33
Amortized	37		38		35

Certain commission plans pay a commission on estimated professional service revenues over the first 12 months of the contract with clients. The portion of commission paid in excess of the actual commission earned in that period is recorded as prepaid commission. When the prepaid commission is considered earned, it is classified as a deferred commission expense and subject to amortization. We did not have material contract liabilities as of December 31, 2025 and 2024.

Insurance Costs

Our insurance plans are provided by third-party insurance carriers under risk-based or guaranteed-cost insurance policies. Under risk-based policies, we agree to reimburse our carriers for any claims paid within an agreed-upon per-person deductible layer up to a maximum aggregate exposure limit per policy. These deductible dollar limits and maximum limits vary by carrier and year. Under guaranteed-cost policies, our carriers establish the premiums and we are not responsible for any deductible.

Insurance costs include insurance premiums for coverage provided by insurance carriers, expenses for claims costs and other risk management and administrative services, reimbursement of claims payments made by insurance carriers or third-party administrators below a predefined deductible limit, and changes in accrued costs related to contractual obligations with our workers' compensation and health benefit carriers.

At policy inception, annual workers' compensation premiums are estimated by the insurance carriers based on projected wages over the duration of the policy period and the risk categories of the WSEs. We initially pay premiums based on these estimates. As actual wages are realized, premium expense recorded may differ from estimated premium expense, creating an asset or liability throughout the policy year. Such asset or liability is reported on our consolidated balance sheets as prepaid expenses or insurance premiums and other payables, respectively.



TRINET	64	2025 FORM 10-K


FINANCIAL STATEMENTS			Table of Contents

Accrued Workers' Compensation Costs

We have secured workers' compensation insurance policies with insurance carriers to administer and pay claims for our clients and WSEs. We are responsible for reimbursing the insurance carriers for losses up to $1 million per claim occurrence (deductible layer). Insurance carriers are responsible for administering and paying claims. We are responsible for reimbursing each carrier up to a deductible limit per occurrence. Accrued workers' compensation costs represent our liability to reimburse insurance carriers for our share of their losses and loss adjustment expenses. These accrued costs are established to provide for the estimated ultimate costs of paying claims within the deductible layer in accordance with workers' compensation insurance policies. These accrued costs include estimates for reported and incurred but not reported (IBNR) losses, accrued costs on reported claims, and expenses associated with settling the claims. In establishing these accrued costs, we use an external actuary to provide an estimate of undiscounted future cash payments that would be made to settle the claims based upon:

•historical volume and severity of workers' compensation cost experience, exposure data and industry loss experience related to TriNet’s insurance policies,

•inputs of WSEs’ job responsibilities and location,

•estimates of future cost trends,

•expected loss ratios for the latest accident year or prior accident years, adjusted for the loss trend, the effect of rate changes and other quantifiable factors, and

•LDFs to project the reported losses for each accident year to an ultimate basis.

We assess the accrued workers' compensation costs on a quarterly basis. For each reporting period, changes in the actuarial methods and assumptions resulting from changes in actual claims experience and other trends are incorporated into the accrued workers' compensation costs. Adjustments to previously established accrued costs estimates are reflected in the results of operations for the period in which the adjustment is identified. Such adjustments could be significant, reflecting any variety of new adverse or favorable trends. Accordingly, final claim settlements may vary materially from the present estimates, particularly when those payments may not occur until well into the future. In our experience, plan years related to workers' compensation programs may take ten years or more to be settled.

We do not discount accrued workers' compensation costs. Costs expected to be paid within one year are recorded as accrued workers' compensation costs. Costs expected to be paid beyond one year are included in accrued workers' compensation costs, less current portion.

We have collateral agreements with various insurance carriers where either we retain custody of funds in trust accounts which we record as restricted cash and cash equivalents, or remit funds to carriers. Collateral whether held by us, or the carriers, is used to settle our insurance and claim deductible obligations to them. Collateral requirements are established at the policy year and are re-assessed by each carrier annually. Based on the results of each assessment, additional collateral may be required for or paid to the carrier or collateral funds may be released or returned to the Company. In instances where we pay collateral to carriers and the agreement permits net settlement of obligations against collateral held, we record our accrued costs net of that collateral (Carrier Collateral Offset). We offset Carrier Collateral Offset against our obligation due within the next 12 months before applying against long-term obligations. Collateral balances in excess of accrued costs are recorded in other assets.

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 2025, 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.



TRINET	65	2025 FORM 10-K


FINANCIAL STATEMENTS			Table of Contents

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 December 31, 2025 and 2024, prepayments and miscellaneous receivables offsetting accrued health insurance costs were $62 million and $60 million, respectively. When the prepaid amount is in excess of our recorded liability the net asset position is included in prepaid expenses. As of December 31, 2025 and 2024, accrued health insurance costs offsetting prepaid expenses were $87 million and $90 million, respectively.

Leases

We determine if a new contractual arrangement is a lease at contract inception. If a contract contains a lease, we evaluate whether it should be classified as an operating or a finance lease. If applicable as a lease, we record our lease liabilities and right-of-use (ROU) assets based on the future minimum lease payments over the lease term and only include options to renew a lease in the future minimum lease payments if it is reasonably certain that we will exercise that option. For certain leases with original terms of twelve months or less we recognize the lease expense as incurred and we do not recognize lease liabilities and ROU assets.

We measure our lease liabilities based on the future minimum lease payments discounted over the lease term. We determine our discount rate at lease inception using our incremental borrowing rate, which is based on our outstanding debts that are collateralized by certain corporate assets. As of December 31, 2025 and 2024, the weighted-average rate used in discounting the lease liability was 5.2% and 4.9%, respectively.

We measure our ROU assets based on the associated lease liabilities adjusted for any lease incentives such as tenant improvement allowances and classify operating ROU assets in other assets in our consolidated balance sheets. For operating leases, we recognize expense for lease payments on a straight-line basis over the lease term.

Cash and Cash Equivalents

Cash and cash equivalents include bank deposits and short-term, highly liquid investments. Investments with original maturity dates of three months or less are considered cash equivalents.

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 ASO 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.

Investments

Our marketable investments are primarily classified as available-for-sale and are carried at estimated fair value.

Unrealized gains and losses are reported as a component of accumulated other comprehensive income, net of deferred income taxes. The amortized cost of debt investments is adjusted for amortization of premiums and accretion of discounts from the date of purchase to the earliest call date for premiums or the maturity date for discounts. Such amortization is included in interest income as an addition to or deduction from the coupon interest earned on the investments. We use the specific identification method to determine realized gains and losses on the sale of available-for-sale securities. Realized gains and losses are included in interest expense, bank fees, and other in the accompanying consolidated statements of income and comprehensive income.

We assess our investments for credit impairment. We review several factors to determine whether an unrealized loss is credit related, such as financial condition and future prospects of the issuer. To the extent that a security's amortized cost basis exceeds the present value of the cash flows expected to be collected from the security, an allowance for credit losses will be recognized. If management intends to sell or will more likely than not be required to sell the security before any anticipated recovery, a write down will be recognized in earnings measured as the entire difference between the amortized cost and the then-current fair value.

We have investments within our unrestricted and our restricted accounts. Unrestricted investments are recorded on the balance sheet as current or noncurrent based upon the remaining time to maturity, and investments subject to restrictions are classified as current or noncurrent based on the expected payout of the related liability.



TRINET	66	2025 FORM 10-K


FINANCIAL STATEMENTS			Table of Contents

Comprehensive Income

Comprehensive income consists of net income and other comprehensive income. Other comprehensive (loss) income includes those gains and losses included in comprehensive income, but excluded from net income, in accordance with GAAP. Other comprehensive (loss) income is primarily comprised of net unrealized gains or losses arising on available-for-sale investments, net of deferred taxes.

Fair Value of Financial Instruments

Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or a liability.

Our financial assets recorded at fair value on a recurring basis are comprised of cash equivalents, available-for-sale marketable securities and certificates of deposits. We measure certain financial assets at fair value for disclosure purposes, as well as on a nonrecurring basis when they are deemed to be other-than-temporarily impaired. Our other current financial assets and liabilities have fair values that approximate their carrying value due to their short-term nature.

Assets and liabilities recorded at fair value are measured and classified in accordance with a three-tier fair value hierarchy based on the observability of the inputs available in the market to measure fair value, summarized as follows:

•Level 1—observable inputs for identical assets or liabilities, such as quoted prices in active markets,

•Level 2—inputs other than the quoted prices in active markets that are observable either directly or indirectly,

•Level 3—unobservable inputs in which there is little or no market data, which requires that we develop our own assumptions.

The fair value hierarchy requires us to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. We classify our cash equivalents, investments and long-term debt in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement in its entirety.

Accounts Receivable

Our accounts receivable represents outstanding gross billings to clients, net of an allowance for estimated credit losses. We require our clients to prefund payroll and related liabilities before payroll is processed or due for payment. If a client fails to fund payroll or misses the funding cut-off, at our sole discretion, we may pay the payroll and the resulting amounts due to us are recognized as accounts receivable. When client payment is received in advance of our performance under the contract, such amount is recorded as client deposits. We establish an allowance for credit losses based on the credit quality of clients, current economic conditions, the age of the accounts receivable balances, historical experience, and other factors that may affect clients’ ability to pay, and charge-off amounts against the allowance when they are deemed uncollectible. The allowance was immaterial at December 31, 2025 and 2024.

Other Payroll Assets and Payroll Tax Liabilities and Other Payroll Withholdings

Included in other payroll assets are expected payroll tax refunds for which we have filed payroll tax returns claiming the refund with the IRS. Included in these receivables are ERTC and other credits that we have filed returns for on behalf of our clients. When we file a claim for a refund that will be passed on to our clients, we recognize a corresponding liability that is recognized in payroll tax liabilities and other payroll withholdings. We also have receivables from the IRS for ERTC claims where we have distributed portions of the receivables to our clients. As of December 31, 2025 and 2024, total ERTC receivables are $384 million and $831 million, respectively. Of this amount $19 million and $72 million have been distributed to our clients as of December 31, 2025 and 2024, respectively.

Property and Equipment

We record property and equipment at historical cost and compute depreciation using the straight-line method over the estimated useful lives of the assets or the lease terms, generally five years to seven years for office equipment, furniture and fixtures, and the shorter of the asset life or the remaining lease term for leasehold improvements. We expense the cost of maintenance and repairs as incurred and capitalize leasehold improvements.



TRINET	67	2025 FORM 10-K


FINANCIAL STATEMENTS			Table of Contents

We periodically assess the likelihood of unsuccessful completion of projects in progress, as well as monitor events or changes in circumstances, which might suggest that impairment has occurred, and recoverability should be evaluated. An impairment loss is recognized if the carrying amount of the asset is not recoverable and exceeds the future net cash flows expected to be generated by the asset.

We evaluate our long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. An asset is considered impaired if the carrying amount exceeds the undiscounted future net cash flows the asset is expected to generate. An impairment charge is recognized for the amount by which the carrying amount of the assets exceeds its fair value. Assets to be disposed of are reported at the lower of the carrying amount or fair value, less selling costs.

Goodwill, Software and Other Intangible Assets

Our goodwill and identifiable intangible assets with indefinite useful lives are not amortized but are tested for impairment on an annual basis or when an event occurs or circumstances change in a way to indicate that there has been a potential decline in the fair value of the reporting unit. Goodwill impairment is determined by comparing the estimated fair value of the reporting unit to its carrying amount, including goodwill. All goodwill is associated with one reporting unit within our one reportable segment.

Annually, we perform a qualitative assessment to determine whether it is more likely than not that the fair value of the reporting unit has declined below its carrying value. This assessment considers various financial, macroeconomic, industry, and reporting unit specific qualitative factors. We perform our annual impairment testing in the fourth quarter. No material impairment loss was recognized in the results of operations for the years ended December 31, 2025, 2024 and 2023.

Intangible assets and software with finite useful lives are amortized over their respective estimated useful lives ranging from one year to six years using either the straight-line method or an accelerated method. Intangible assets are reviewed for indicators of impairment at least annually and evaluated for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Based on the results of our reviews, we recognized an impairment loss of $22 million on intangible assets in the results of operations for the year ended December 31, 2024.

We capitalize internal and external costs incurred to develop internal-use computer software during the application development stage. Application development stage costs include software configuration, coding, and installation. Capitalized costs are amortized on a straight-line basis over the estimated useful life, typically ranging from three years to six years, commencing when the software is placed into service. We expense costs incurred during the preliminary project stage, as well as general and administrative, overhead, maintenance and training costs, and costs that do not add functionality to existing systems.

Advertising Costs

We expense the costs of producing advertisements at the time production occurs, and expense the cost of running advertisements in the period in which the advertising space or airtime is used as sales and marketing expense. Advertising costs were $19 million, $20 million, and $37 million for the years ended December 31, 2025, 2024 and 2023, respectively.

Stock Based Compensation

Our stock-based awards to employees include time-based and performance-based restricted stock units and restricted stock awards, stock options and an employee stock purchase plan. Compensation expense associated with restricted stock units and restricted stock awards is based on the fair value of common stock on the date of grant. Compensation expense associated with stock options and employee stock purchase plan are based on the estimated grant date fair value method using the Black-Scholes option pricing model. Expense is recognized using a straight-line amortization method over the respective vesting period for awards that are ultimately expected to vest, with adjustments to expense recognized in the period in which forfeitures occur.

Income Taxes

We account for our provision for income taxes using the asset and liability method, under which we recognize income taxes payable or refundable for current year and deferred tax assets and liabilities for the future tax effect of events that have been recognized in either our financial statements or tax returns. We measure our current and deferred tax assets and liabilities based on provision of enacted tax laws of those jurisdictions in which we operate. The effect of changes in tax laws and regulations, or interpretations, is recognized in our consolidated financial statements in the period that includes the enactment date.

We recognize deferred tax assets and liabilities based on temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and amounts used for income tax purposes, as well as the expected benefits of using net operating loss and other carryforwards. We establish a valuation allowance when it is determined more likely than not that the deferred tax assets will not be realized. Provision for income taxes may change when estimates used in determining valuation allowances change or when receipt of new information indicates the need for adjustment in valuation allowances. Changes in valuation allowances are reflected as a component of the provision for income taxes in the period of adjustment.

We recognize a reserve for uncertain tax positions taken or expected to be taken in a tax return when it is concluded that tax positions are not more likely than not to be sustained upon examination by taxing authorities, including resolution of any related appeals or litigation processes, based on the technical merits of the positions. Assumptions, judgment and the use of estimates are required in determining if the more likely than not standard has been met when developing the provision for income taxes and in determining the expected benefit. The tax benefits of the position recognized in the financial statements are then measured based on the largest amount of benefit that is greater than 50% likely to be realized upon settlement with a taxing authority. Unrecognized tax benefits due to tax uncertainties that do not meet the minimum probability threshold are included as other liabilities and are charged to earnings in the period that such determination is made. We recognize interest and penalties related to uncertain tax positions as a component of income tax expense. Accrued interest and penalties are included in other non-current liabilities on the consolidated balance sheets.

Concentrations of Credit Risk

Financial instruments subject to concentrations of credit risk include cash, cash equivalents and investments (unrestricted and restricted), accounts receivable, and amounts due from insurance carriers. We maintain these financial assets principally in domestic financial institutions. We perform periodic evaluations of the relative credit standing of these institutions. Our exposure to credit risk in the event of default by the financial institutions holding these funds is limited to amounts currently held by the institution in excess of insured amounts.

Under the terms of professional services agreements, clients agree to maintain sufficient funds or other satisfactory credit at all times to cover the cost of their current payroll, all accrued paid time off, vacation or sick leave balances, and other vested wage and benefit obligations for all their work site employees. We generally require payment from our clients on or before the applicable payroll date.

For certain clients, we require an indemnity guarantee payment (IGP) supported by a letter of credit, bond, or a certificate of deposit from certain financial institutions. The IGP typically equals the total payroll and service fee for one average payroll period.

No client accounted for more than 10% of total revenues in the years ended December 31, 2025, 2024 and 2023. Bad debt expense, net of recoveries was $3 million for the years ended December 31, 2025, 2024, and 2023.

Disaggregation of Income Statement Expenses

In December 2024, FASB issued ASU 2024-03, Disaggregation of Income Statement Expenses, is to enhance the transparency and decision-usefulness of financial reporting by requiring public business entities to provide more detailed disclosures about the components of certain expense captions in their income statements. The ASU is effective for TriNet on a prospective basis for annual periods beginning after December 15, 2026. The Company is currently evaluating the provisions of this ASU.

Internal-Use Software

In September 2025, FASB issued ASU 2025-06, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software (ASU 2025-06) which amends the guidance in ASC 350-40, Intangibles—Goodwill and Other—Internal-Use Software. The amendments modernize the recognition and disclosure framework for internal-use software costs, removing the previous “development stage” model and introducing a more judgment-based approach. ASU 2025-06 is effective for fiscal years beginning after December 15, 2027, and for interim periods within those annual reporting periods, with early adoption permitted. The Company is currently evaluating the provisions of this ASU.

Income Taxes

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which enhances income tax disclosure requirements. The ASU mandates additional details in the income tax rate reconciliation, including quantitative thresholds for reconciling items, and requires disaggregation of income taxes paid by federal, state, and foreign jurisdictions, with further breakdowns for significant individual jurisdictions. We adopted this ASU in 2025 using a retrospective approach. The adoption of this ASU did not have a material impact on the Company’s financial position, results of operations, or cash flows but enhanced the disclosure of its income tax disclosures. Refer to Note 12 in Part II, Item 8. Financial Statements and Supplementary Data, of this Form 10-K.

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-related liabilities. Also included in restricted cash are payroll tax refunds received that have not yet been remitted to clients pending our determination of allocation of payments to clients on the gross receipts from tax authorities.

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:

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 balance sheets as of December 31, 2025 and December 31, 2024. There were no transfers between levels as of December 31, 2025 and December 31, 2024.

Unrealized Losses on AFS Investments

Unrealized losses on fixed income securities are principally caused by changes in market interest rates and the financial condition of the issuer. In analyzing an issuer's financial condition, we consider whether the securities are issued by the federal government or its agencies, whether downgrades by credit rating agencies have occurred, and industry analysts' reports. Actual maturities may differ from contractual maturities because borrowers may have the right to prepay obligations with or without prepayment penalties. Gross unrealized losses were immaterial at December 31, 2025 and December 31, 2024.

Fair Value of Long-Term Debt

As of December 31, 2025, our 2029 Notes and 2031 Notes were carried at their cost, net of issuance costs, and had a fair value of $473 million and $414 million, respectively. As of December 31, 2024, our 2029 Notes and 2031 Notes were carried at their cost, net of issuance costs, and had a fair value of $453 million and $408 million, respectively. 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.

Our 2021 Revolver is a floating rate debt. At December 31, 2025, we do not have any outstanding balance under our 2021 Revolver. At December 31, 2024, 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. The entire outstanding balance of $90 million under our 2021 Revolver was paid off in July 2025.

As part of our 2024 restructuring discussed in Note 16, we classified approximately $7 million of assets and an immaterial amount of liabilities as held for sale and compared the carrying value of those assets to their estimated fair value, which was based on their estimated selling price. The assets and liabilities were sold in 2025. This resulted in a $1 million goodwill impairment for 2024.

The following summarizes software and other intangible assets:

Amortization of intangible assets during the years ended December 31, 2025, 2024 and 2023 was $61 million, $68 million and $63 million, respectively. We evaluate the remaining useful life of intangible assets annually to determine whether events and circumstances warrant a revision to the estimated remaining useful life. In 2024, in connection with our restructuring discussed in Note 16, we recognized an impairment charge of $24 million related to customer relationships assets, which was classified in G&A in our Consolidated statement of income and comprehensive income. This impairment charge was determined using a discounted cash flows model and Level 3

Incurred claims related to prior years represent changes in estimates for ultimate losses on workers' compensation claims. For the years ended December 31, 2025, 2024 and 2023, the favorable development is due to lower than expected reported claim frequency and severity for the more recent years.

As of December 31, 2025 and 2024, we had $25 million and $26 million of collateral held by insurance carriers of which $3 million and $4 million, respectively, was offset against accrued workers' compensation costs as the agreements permit and are net settled of insurance obligations against collateral held.

NOTE 7. LEASES

Our leasing activities predominantly consist of leasing office space that we occupy, which we have classified as operating leases. Our leases are comprised of fixed payments with remaining lease terms of 1 to 13 years. As of December 31, 2025, we have not included any options to extend or cancel in the calculation of our lease liability or ROU asset. We do not have any significant residual value guarantees or restrictive covenants in our leases.

In 2025, the Company executed an operating lease agreement to lease new office space in Atlanta, Georgia. The lease commenced in the second quarter of 2025 and expires in 2038.

We recognized operating lease expense of $12 million, $15 million and $11 million for the years ended December 31, 2025, 2024 and 2023, respectively. For the years ended December 31, 2024 and 2023, we recognized $5 million, and $6 million, respectively, of lease impairment due to the closing of several offices. We did not recognize any lease impairment for the year ended December 31, 2025.

As of December 31, 2025 and 2024, the weighted average remaining lease term on our operating leases was 6.8 years and 3.8 years, respectively. Future minimum lease payments as of December 31, 2025 were as follows:

In September of 2023, we drew down $200 million of our 2021 revolver to partially fund our third quarter of 2023 share repurchases. In 2024, we repaid $110 million of the outstanding balance. In 2025, the remaining outstanding balance of $90 million was paid off.

In February 2021, we issued $500 million aggregate principal of 3.50% senior unsecured notes maturing in March 2029 (our 2029 Notes). The 2029 Notes are a senior unsecured obligation of TriNet Group, Inc. and rank equally with all of its existing and future senior unsecured indebtedness. Interest payments on the 2029 Notes are due semi-annually in arrears on March 1 and September 1, beginning on September 1, 2021. The net proceeds were used to repay and terminate our 2018 Term Loan and for general corporate purposes.

We may voluntarily redeem the 2029 Notes, in whole or in part,(1) at any time on or after March 1, 2024 at a prepayment price equal to 101.75% of the principal amount; (2) at any time on or after March 1, 2025 at a prepayment price equal to 100.875%of the principal amount; and (3) at any time on or after March 1, 2026 at a prepayment price equal to 100% of the principal amount; in each case, plus accrued and unpaid interest, if any, to but excluding, the date of redemption.

In August 2023, we issued $400 million aggregate principal of 7.125% senior unsecured notes maturing in August 2031 (our 2031 Notes). Interest payments on the 2031 Notes are due semi-annually in arrears on February 15 and August 15, beginning on February 15, 2024. We used the net proceeds to fund an equity tender offer and a private share repurchase, each of which were executed in the third quarter of 2023 (including the related fees and expenses).

We may voluntarily redeem all or a part of the 2031 Notes on or after August 15, 2026, on any one or more occasions, at the redemption prices set forth in the indenture governing the 2031 Notes, plus, in each case, accrued and unpaid interest thereon, if any, to, but excluding, the applicable redemption date. In addition, at any time prior to August 15, 2026, we may on any one or more occasions redeem up to 40% of the aggregate principal amount of the 2031 Notes outstanding under the indenture governing the 2031 Notes with the net cash proceeds of one or more equity offerings at a redemption price equal to 107.125% of the principal amount of the 2031 Notes then outstanding, plus accrued and unpaid interest thereon, if any, to, but excluding the applicable redemption date. At any time prior to August 15, 2026, we may also redeem all or a part of the 2031 Notes at a redemption price equal to 100% of the principal amount of the 2031 Notes redeemed plus a “make-whole” premium as of, and accrued and unpaid interest, if any, to, but excluding, the applicable redemption date.

The annual interest rate for borrowings under our 2021 Revolver was calculated based on the forward-looking Secured Overnight Financing Rate (Term SOFR). Term SOFR loans will be charged interest at the Term SOFR rate (subject to a 0.00% floor), plus a margin between 1.25% and 2.00%, depending on the Company’s total net leverage ratio, plus a credit adjustment spread of 10 basis points for all tenors (such Term SOFR rate plus the credit adjustment spread, the "Adjusted Term SOFR Rate"). The applicable Term SOFR or ABR margin is based on our Total Leverage Ratio, as defined in the 2021 Credit Agreement. The ABR is the highest of (a) the applicable Federal Reserve Bank of New York rate in effect on such day (which rate is the greater of the Federal funds Effective Rate in effect on such day and the Overnight Bank Funding Rate in effect on such day), as defined in our 2021 Credit Agreement plus 0.50% (b) the prime rate in effect on such day, and (c) the Adjusted Term SOFR Rate for a one month interest period, as published by two U.S. Government Securities Business Days prior to such day daily plus 1.00%. The interest rate for 2025 borrowings under our 2021 Revolver was 5.527% - 5.669%. As of December 31, 2025, we had remaining capacity of $699 million under our 2021 Revolver.

In the event TriNet Group, Inc. receives a Corporate Issuer Credit Rating that is one level below investment grade rating or higher from at least two Nationally Recognized Statistical Rating Organizations, then rating based pricing



TRINET	76	2025 FORM 10-K


FINANCIAL STATEMENTS			Table of Contents

applies and, for so long as rating-based pricing applies, irrespective of the Total Leverage Ratio, the Term SOFR margin will be 1.125% and the ABR margin will be 0.125%.

The indenture governing our 2029 Notes and 2031 Notes each includes restrictive covenants limiting our ability to: (i) create liens on certain assets to secure debt; (ii) grant a subsidiary guarantee of certain debt without also providing a guarantee of the 2029 Notes or 2031 Notes, as applicable; and (iii) consolidate or merge with or into, or sell or otherwise dispose of all or substantially all of our assets to, another person, subject, in each case, to certain customary exceptions.

The 2021 Credit Agreement includes negative covenants that limit our ability to incur indebtedness and liens, sell assets and make restricted payments, including dividends and investments, subject to certain exceptions. In addition, the 2021 Credit Agreement also contains other customary affirmative and negative covenants and customary events of default. The 2021 Credit Agreement also contains a financial covenant that requires the Company to maintain certain maximum total net leverage ratios. We were in compliance with all financial covenants under the 2021 Credit Agreement, 2029 Notes and 2031 Notes at December 31, 2025.

NOTE 9. 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, regulatory investigations 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 10. STOCK BASED COMPENSATION

Equity Based Incentive Plans

Our 2019 Equity Incentive Plan and as amended and restated (the 2019 Plan), approved in May 2019, provides for the grant of stock awards, including stock options, RSUs, RSAs, and other stock awards. There were approximately 4 million shares available for grant under the 2019 Plan as of December 31, 2025.

The 2009 Equity Incentive Plan (the 2009 Plan), was replaced by the 2019 Plan, except that any outstanding awards granted under the 2009 Plan remain in effect pursuant to their terms.

Restricted Stock Units (RSUs)

Time-based RSUs generally vest over a four-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 under performance-based RSUs may range from 0% to 200% of the target award. Performance-based awards granted in 2025, 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 in one 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 fair value of our RSUs is equal to the fair value of our common stock on the grant date.

Employee Stock Purchase Plan

Our 2014 ESPP offers eligible employees an option to purchase shares of our common stock through payroll deductions. The purchase price is equal to the lesser of 85% of the fair market value of our common stock on the offering date or 85% of the fair market value of our common stock on the applicable purchase date. Offering periods are approximately six months in duration and will end on or about May 15 and November 15 of each year. The plan is considered to be a compensatory plan. As of December 31, 2025, approximately 6 million shares were reserved for future issuances under the ESPP.

In applying the Black Scholes option valuation model for the ESPP options, we use the following assumptions:

Stock Options

Stock options are granted to eligible employees at exercise prices equal to the fair market value of our common stock on the dates of grant. Stock options generally have a maximum contractual term of 10 years. Stock options vest after 3 years, and are generally forfeited if the employee terminates service prior to vesting.

The following table summarizes stock option activity for the year ended December 31, 2025:

We estimated the fair value of stock options using the Black-Scholes option-pricing model. Because we do not have significant exercise history in granting stock options, we estimate the expected term using the simplified method. We estimate expected volatility using the daily historical trading data of our common shares. The table below summarizes the assumptions used.

The fair value of stock options is estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions:

(1) State taxes in California, New York State and New York City made up the majority (greater than 50%) of the tax effect in this category.

Our effective income tax rate increased by 6% to 29% in 2025 from 23% in 2024. The increase in the rate as compared to the same periods of 2024 was primarily attributable to decreases in tax benefits for stock-based compensation and charges to valuation allowances.

Global tax developments from the Organization for Economic Cooperation and Development proposes implementation of a global minimum tax under the Pillar Two model rules. Management has determined this development applicable to multinational businesses does not have a material impact to our business, cash flows, or financial results.

NOTE 16. RESTRUCTURING

During the fourth quarter of 2024, we completed a detailed review of our strategy and made several decisions that would narrow and intensify our focus on our U.S. PEO business. This includes winding down the software-only HRIS product as well as other immaterial products not directly related to our U.S. PEO business. In place of our software-only HRIS product, we now focus our ASO services to include both the software component, but also a significant service component similar to the types of services we provide to PEO clients.

In conjunction with this adjustment to our product offerings, we have implemented changes to our operating expense structure, including reductions to our staffing and office footprint.

As part of the restructuring initiatives, the Company incurred the charges shown in the following table. These expenses are classified in G&A in our Consolidated statement of income and comprehensive income.


	Year Ended December 31,		Year Ended December 31,

We expect the restructuring efforts to continue through 2026 and may recognize additional expenses as they are incurred.

NOTE 17. SEGMENT INFORMATION

We operate in one reportable segment. Our chief operating decision maker for segment reporting purposes is our CEO, who uses the profitability and significant expense detail to allocate resources and assess performance based on key functions such as customer acquisition, customer service, and indirect costs.

The primary measure of profit or loss that the CEO uses is net income. The significant expenses used in these profit or loss reports align with the primary functions of the corresponding teams, with the exception of non-cash expenses such as depreciation, amortization and stock based compensation as these expenses are not necessarily indicative of our ongoing operations. In this expense reporting methodology, overhead-type expenses, such as facilities and technology support for colleagues, are classified consistent with the primary function of the corresponding teams and not allocated to other significant expenses.

Management’s Report on Internal Control Over Financial Reporting

We are responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) promulgated under the Exchange Act to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the financial statements for external purposes in accordance with GAAP.

Due to inherent limitations, internal control over financial reporting is not intended to provide absolute assurance that a misstatement of our financial statements would be prevented or detected. 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 policies or procedures may deteriorate.

We have performed an assessment of the effectiveness of our internal control over financial reporting as of December 31, 2025 based upon criteria set forth in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

Based on this assessment, we determined that our internal control over financial reporting was effective as of December 31, 2025.

Deloitte & Touche LLP, our independent registered public accounting firm, has issued an audit report on the effectiveness of our internal control over financial reporting as of December 31, 2025. This audit report appears in Part II, Item 8. Financial Statements and Supplementary Data, of this Form 10-K.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting that occurred during the three months ended December 31, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
