PART I

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

Certain written and oral statements made by management of Paychex, Inc. and its wholly owned subsidiaries (“Paychex,” the “Company,” “we,” “our,” or “us”) may constitute “forward-looking statements” within the meaning of the safe harbor provisions of the United States (“U.S.”) Private Securities Litigation Reform Act of 1995. Forward-looking statements can be identified by such words and phrases as “expect,” “estimate,” “intend,” “intent,” “outlook,” “will,” “would,” “guidance,” “projections,” “strategy,” “mission,” “anticipate,” “believe,” “can,” “could,” “design,” “look forward,” “may,” “target,” “possible,” “potential,” “purpose,” “design,” “might,” “should,” and other similar words or phrases. Forward-looking statements include, without limitation, all matters that are not historical facts. Examples of forward-looking statements include, among others, statements we make regarding the integration of Paycor HCM, Inc. ("Paycor"), operating performance, events, or developments that we expect or anticipate will occur in the future, including statements relating to our outlook, revenue growth, earnings, earnings-per-share growth, and similar projections.

Forward-looking statements are neither historical facts nor assurances of future performance. Instead, they are based only on our current beliefs, expectations, and assumptions regarding the future of our business, future plans and strategies, projections, anticipated events and trends, the economy, and other future conditions. Because forward-looking statements relate to the future, they are subject to known and unknown uncertainties, risks, changes in circumstances, and other factors that are difficult to predict, many of which are outside our control. Our actual performance and outcomes, including without limitation, our actual results and financial condition may differ materially from those indicated in or suggested by the forward-looking statements. Therefore, you should not rely on any of these forward-looking statements. Important factors that could cause our actual results and financial condition to differ materially from those indicated in the forward-looking statements include, among others, the following:

Any of these factors, as well as such other factors as discussed in Part I, Item 1A, “Risk Factors” and throughout Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of this Annual Report on Form 10‑K (“Form 10-K”), and in our periodic filings with the Securities and Exchange Commission (the “SEC”), could cause our actual results to differ materially from our anticipated results. The information provided in this Form 10‑K is based upon the facts and circumstances known as of the date of this report, and any forward-looking statements made by us in this Form 10‑K speak only as of the date on which they are made. Except as required by law, we undertake no obligation to update these forward-looking statements after the date of filing this Form 10-K with the SEC to reflect events or circumstances after such date, or to reflect the occurrence of unanticipated events.

Our investor presentation regarding the financial results for the fiscal year ended May 31, 2025 is available and accessible on our Paychex Investor Relations portal at https://investor.paychex.com. Information available on our website is not a part of, and is not incorporated into, this Form 10-K. We intend to make future investor presentations available exclusively on our Paychex Investor Relations portal.

Item 1. Business

Unless we state otherwise or the context otherwise requires, the terms “Paychex,” “we,” “us,” “our” and the “Company” refer to Paychex, Inc., a Delaware corporation, and its consolidated subsidiaries.

Overview

We are an industry-leading human capital management (“HCM”) company delivering a full suite of technology and advisory solutions in human resources (“HR”), employee benefit solutions, insurance, and payroll processing. As of May 31, 2025, we served approximately 800,000 clients and their employees across the U.S. and parts of Europe. Paychex was incorporated in Delaware in 1979, maintains a corporate headquarters in Rochester, New York, and has a fiscal year that ends on May 31st.

For any organization, a key function is effective human capital management, which requires resources and expertise. Organizations are faced with rapid evolution in employer-employee relations including: an increasing number and complexity of federal, state, and local regulations; changing workforce dynamics; and challenges attracting and retaining talent. Changing workplace dynamics reflect employees increasingly becoming mobile, working remotely, and expecting a user experience similar to consumer-oriented applications.

We specialize in helping clients adapt to the rapidly evolving environment. Paychex offers a full range of integrated HCM solutions from hire to retire for businesses and their employees that enables customization to the clients' businesses, whether it is small or large, simple or complex. We believe that we have the breadth of solutions to cover the full spectrum of the employee life cycle, while also enabling integrations with popular HR, accounting, enterprise resource planning (“ERP”), and point-of-sale applications.

Key features of our solutions include:

We market our solutions through a combination of direct and virtual sales forces supported by various digital lead generation and multi-channel marketing initiatives. Over 50% of our revenues are from solutions other than payroll processing.

On April 14, 2025, we completed our acquisition of Paycor HCM, Inc. ("Paycor"), a leading provider of HCM, payroll and talent software. The transaction aims to enhance the Company’s capabilities upmarket, expand its sales force and enhance its suite of AI-driven HCM solutions.

Company Strategy

Our strategy is to be the digitally driven HR leader, serving as an essential partner to clients by providing them with the technology and advisory solutions they need for HR, payroll, benefits, and insurance. We believe that successfully executing this strategy will lead to strong, long-term financial performance. We intend to strengthen and extend our position as a leading provider through continued investments in both our innovative technology and HR advisory solutions. Key elements of our strategy include:

Our Clients

We provide HCM solutions to a diverse client base operating in a broad range of industries throughout the U.S. and parts of Europe. The flexibility and scalability of our solutions enable our clients to select the best solution that meets their needs. We utilize service agreements and arrangements with clients that generally do not contain specified contract periods and may be terminated by either party with 30-days’ notice of termination.

We believe client retention is a useful indicator of client satisfaction with our solutions and support. For fiscal 2025, our client retention of Paychex clients was in the range of 82% to 83% of our beginning client base.

Our Solutions

We provide a unique blend of innovative technology solutions, backed by our extensive compliance and HR expertise, that help customers more effectively hire, develop, and retain top talent in this challenging workforce environment. Clients have the option of processing payroll online using our SaaS technology, outsourcing to our payroll specialists, or using a combination of these methods. Payroll is integrated with HCM software modules for clients who have more complex HR needs. We continue to invest in our technology, enhancing our solutions to continuously improve the customer and employee experiences from hire to retire.

We also provide comprehensive HR outsourcing through our administrative services organization (“ASO”) and professional employer organization (“PEO”) solutions. We have over 650 HR business professionals who are dedicated to our clients and have the experience and training to provide HR best practices and advice. Our HR business partners are available to provide our ASO and PEO clients with guidance on HR issues. The integration of leading-edge technology and flexible support options enables us to meet our clients’ needs, from the tactical to the strategic.

We closely monitor the evolving challenges and needs of our clients, and proactively aid our clients in navigating macroeconomic challenges, legislative changes, and other complexities they may face. Over the past year, top challenges for employers were macroeconomic pressures including inflation and interest rates, availability of qualified talent, providing appropriate employee development, keeping technology current, and ensuring legal and regulatory compliance. We have approximately 250 compliance professionals who are in real-time contact with tax agencies and regulators to understand upcoming or newly enacted laws and regulations. The contributions of these compliance experts are intended to ensure that our HCM solutions are updated in a timely fashion to adhere to applicable regulations and to help our clients stay in compliance.

Management Solutions:

We offer a comprehensive portfolio of HCM technology and HR advisory solutions that enable our clients to meet their diverse HR and payroll needs.

PEO and Insurance Solutions:

We provide comprehensive employment outsourcing and insurance solutions to best meet our clients’ needs.

Sales and Marketing

We market and sell our solutions primarily through our direct sales force based in the markets we serve. Our direct sales force includes field and inside sales representatives who specialize within our portfolio of solutions. Our sales representatives are also supported by marketing, advertising, public relations, and various other demand generation programs.

In addition to our direct selling and marketing efforts, we utilize other indirect sales channels such as our relationships with existing clients, certified public accountants (“CPAs”), benefit brokers, and banks for new client referrals. More than 50% of our payroll clients come from these referral sources. Our dedicated business development group drives sales through banking, national associations, and franchise channels. Complementing our direct sales, our Embedded HCM Solution partnerships efficiently extend our distribution while providing a modern, holistic solution to customers. We also utilize digital marketing to promote our solutions.

We have a long-standing partnership with the American Institute of Certified Public Accountants (“AICPA”) as the preferred payroll provider for its AICPA Business Solutions™ Program. Our current partnership agreement with the AICPA is in place through September 2027. We also partner with numerous state CPA society organizations. We provide a free online portal, Paychex Partner Pro, designed to provide accountants quick access to critical data, reporting, and insights for their clients using Paychex Flex. This innovative portal transforms how CPAs manage their portfolios by providing a centralized hub for accessing client payroll and HR data, resolving issues, and identifying missing information, empowering them to operate with greater efficiency and proactivity in serving their clients.

We also have long-standing relationships with health insurance and retirement benefits brokers, including large national partners. We recently launched the Partner+ Program to foster broker relationships and drive mutual growth. We now have a broader suite of solutions to offer brokers, which can supplement their offerings to clients, and the Partner+ Program provides a structured framework designed to safeguard mutual clients from competing products. In addition, our Partner Portal provides brokers exclusive access to advanced HCM solutions, new revenue streams, and data-driven insights.

Our corporate website is available at www.paychex.com, and is a cost-efficient channel that serves as a source of leads and new sales, while complementing the efforts of our direct, indirect, and virtual sales forces. The website enables us to market to existing and prospective clients that want to learn more about our solutions and support, and offers information about our core business solutions: human resources, payroll, benefits, and insurance.

Paychex also builds on its reputation as an expert in the HCM industry by providing educational resources to our clients. We provide free webinars, podcasts, white papers, and other information on our website to inform businesses on the impact of regulatory change as well as HR and business best practices. Paychex WORX and the Paycor HR Center for Excellence provide information on the latest trends, best practices, and industry benchmarks designed to drive business success.

We also track current regulatory issues that impact the business community and provide regulatory updates. We issue small business trend reports through our monthly Paychex Small Business Employment Watch.

Markets and Competition

We remain focused on servicing clients based upon the growth potential that we believe exists in the markets we serve. Census data indicates that in the U.S., there are over 6 million employer firms in our target markets.

The market for HCM solutions is highly competitive and fragmented. We have one primary national competitor and we also compete with other national, international, regional, local, and online payroll providers. In addition to traditional payroll processing and HR solution providers, we compete with in-house payroll and HR systems and departments. We believe our solutions also compete with a variety of providers of HR services, such as retirement solutions companies, insurance companies, HR and benefits consulting firms, and national and regional PEOs.

Competition in the HCM industry is primarily based on the breadth of offerings, technology, ease of use, integration with third-party applications, service model, and price. We believe we are competitive in each of these areas. Our leading-edge technology and mobile applications, combined with personalized support provided by industry professionals and our technology-enabled solution capabilities, differentiate us from our competitors.

Software Maintenance and Development

The ever-changing mandates of federal, state, and local tax and regulatory agencies require us to regularly update our proprietary software to provide payroll and HCM solutions to our clients. We are continually engaged in developing enhancements to and maintaining our various software platforms to meet the changing requirements of our clients and the marketplace. We continue to enhance our SaaS solutions and mobile applications to offer our users an integrated and unified experience. Continued enhancement of the client and client employee experience is important to our future success.

Human Capital

We believe our ability to attract and retain qualified employees in all areas of our business is critical to our future success and growth. We strive to foster a workplace that encompasses belonging and engagement and the ability to attract, retain, and develop talented employees; and keep them safe. We have dedicated resources to ensure that our efforts in building and sustaining a safe and inclusive culture are realized.

For detailed information regarding our human capital activities, we encourage investors to visit our Corporate Responsibility website page at https://www.paychex.com/corporate/corporate-responsibility. We have also made our Corporate Responsibility report available on our website. The information contained on our website and in our Corporate Responsibility report is not and should not be viewed as being incorporated by reference into this Form 10-K.

Our Employees: As of May 31, 2025, we employed approximately 19,000 people, primarily in the U.S. and on a full-time basis. None of our employees were covered by collective bargaining agreements. We have not experienced a strike or similar work stoppage, and we consider our relations with our employees to be good.

Paychex Culture: Our core cultural values (“Paychex Values”) are designed to guide decision making aligned to the expectations of clients, stockholders, regulators, employees, and the multiple communities in which we operate and to reflect our continuing commitment to belonging and engagement. The Paychex Values are:

Each of these values guide our decision-making process and are critical to our ongoing success. All employees are required to verify their understanding and observance of these values during our annual “Right Way” training, review these values with management during periodic performance discussions, and are further encouraged to attend ongoing training during the year. Volunteer “Culture Champions” throughout the Company also help promote these values daily. We encourage employee feedback through our employee engagement surveys, as described below. This approach empowers our employees and allows us to make a positive impact in the communities we work and serve. As a result of our commitment to these principles, in 2025 we were recognized by Ethisphere, a global leader in defining and advancing the standards of ethical business practices, as one of the World’s Most Ethical Companies. Paychex is one of only three companies to have achieved this recognition 17 times, doing so consecutively since 2012.

Talent Acquisition and Development: We compete for talent along with our direct competitors and other companies in the geographic areas we serve. We invest significant resources to attract and retain top talent. Our Talent Acquisition team, in conjunction with certain third-party partners, has developed comprehensive processes to identify and recruit accomplished professionals.

Once hired, our world-class Training Department provides functional training for service specialists and sales associates and also offers personal training, professional development, and leadership-development programs. As a result of our efforts, we have been recognized as one of the top training organizations in the world by Training magazine. After four consecutive years ranking among the top ten, Paychex was inducted into the Training Hall of Fame in 2025.

Comprehensive Compensation and Benefits: We are committed to providing a fair wage and a total rewards package that allows our employees to be their best in every area of their lives. We regularly review employee salaries to ensure we are competitive in the industry and offer financial benefits such as a 401(k) plan, employee stock purchase plan, tuition assistance, scholarships for children of employees, and financial education. We are also committed to rewarding employees with a comprehensive, competitive benefits package, which includes medical, prescription, dental, and vision insurance, short- and long-term disability, employee assistance program, paid family leave, and a variety of well-being programs. For the fiscal year ended May 31, 2025 (“fiscal 2025”), compensation-related expenses accounted for approximately 55% of our total expenses.

Employee Well-being Initiatives: In addition to providing a comprehensive compensation and benefits package, we are committed to providing a safe and healthy workplace for our employees. Healthier employees are at lower risk of injury from workplace related exposures, perform work more safely with lower rates of absenteeism, experience better job performance, and can live their lives more fully outside of work. Our well-being program is a robust program focusing on the physical, emotional, community, career, and financial health of our employees.

Our award-winning well-being initiatives offer a wide variety of services, tools, and resources that can help employees achieve their health goals using a holistic approach. In addition, we sponsor onsite health screenings, Red Cross blood donation events, flu vaccination clinics, vaping and tobacco cessation and weight management programs, meditation and yoga classes, and a variety of other programs. Our employees’ financial well-being is equally important, so we have developed programs for financial education and support. We maintain procedures for events such as fires, severe weather, medical emergencies, and active shooters, as well as other important information related to general workforce safety.

In recognizing the ever-growing diversity of our workplace, we annually celebrate Paychex Culture Day. This is an additional paid day off for employees to celebrate and recognize a holiday that is significant to them. This is just one of the many ways we celebrate our employees’ unique heritages, and it reflects our Company's commitment to our staff.

Employee Engagement: We regularly ask our employees to share their views on working at Paychex through company-wide engagement surveys. Facilitated internally by our Human Resources team, the survey methodology is periodically updated to reflect current trends and issues including company direction and strategy, inclusion, individual development, collaboration, and our Paychex Values. A third-party administers the survey to maintain confidentiality of responses. We use the survey responses to help inform management and assist in developing programs and policies that will maintain and promote Paychex Values.

Intellectual Property

We own or license and use a number of trademarks, trade names, copyrights, service marks, trade secrets, computer programs and software, and other intellectual property rights. Collectively, our intellectual property rights are material to the conduct of our business. Where it is determined to be appropriate, we take measures to protect our intellectual property rights, including, but not limited to, confidentiality/non-disclosure agreements or policies with employees, vendors, and others; license agreements with licensees and licensors of intellectual property; and registration of certain trademarks. We believe that the “Paychex” name, trademark, and logo are of material importance to us.

Seasonality

There is no significant seasonality to our business. However, during our third fiscal quarter, which ends in February, the number of new payroll clients, new retirement solutions clients, and new worksite employees associated with our HR Outsourcing businesses tends to be higher than during the rest of the fiscal year, primarily because many businesses prefer to start using our solutions at the beginning of a calendar year. In addition, calendar year-end transaction processing and client funds activity are traditionally higher during our third fiscal quarter due to year-end bonus payments, additional year-end services, and the preparation and delivery of end-of year reporting requirements.

Available Information

We are subject to the informational and reporting requirements of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Therefore, we file periodic reports, proxy statements, and other information with the SEC. The SEC maintains a website (www.sec.gov) that includes our reports, proxy statements, and other information.

Our corporate website, www.paychex.com, provides materials for investors and information about our solutions. Our Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K, and other SEC filings, as well as any amendments to such reports filed or furnished pursuant to Section 13(a) or 15(d) of the Exchange Act, are made available, free of charge, on our website as soon as reasonably practicable after such reports have been filed with or furnished to the SEC. The information on our website is not incorporated by reference into our Form 10-K. Also, copies of our Annual Report to Stockholders and Proxy Statement, to be issued in connection with our 2025 Annual Meeting of Stockholders, will be made available, free of charge, upon written request submitted to Paychex, Inc., c/o Corporate Secretary, 911 Panorama Trail South, Rochester, New York 14625-2396.

Item 1A. Risk Factors

Our future results of operations are subject to risks and uncertainties that could cause actual results to differ materially from historical and current results, and from our projections. The following risk factors represent our current view of some of the most important risks facing our business and are important to understanding our business. These are not the only risks we face. Additional factors not presently known to us or that we currently deem to be immaterial also may adversely affect, possibly to a material extent, our business, cash flows, financial condition, or results of operations in future periods. In addition, refer to the cautionary note regarding forward-looking statements at the beginning of Part I of this Form 10-K.

Business and Operational Risks

We may not be able to keep pace with changes in technology or provide timely enhancements to our solutions and support.

The market for our solutions is characterized by rapid technological advancements, 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. 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, including the successful utilization of AI and machine learning solutions; enhance capabilities and increase the performance of our internal systems, particularly our systems that meet our clients’ requirements; and adapt to technological advancements and changing industry standards. 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. There can be no assurance 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. The failure to continually develop enhancements and use of technologies such as robotics and other workflow automation tools, natural language processing, and AI/machine learning may impact our ability to increase the efficiency of and reduce costs associated with operational risk management and compliance activities.

We may experience software defects, undetected errors, and development delays, which could damage our relationship with clients, decrease our potential profitability and expose us to liability.

Our solutions rely on software and computing systems, including generative AI solutions, that can encounter development delays, complexities with integrating new technologies, and the underlying software may contain undetected errors, bias, viruses, or defects. Defects in our solutions, errors or delays caused by our solutions and generative AI solutions not working as anticipated could result in additional development costs, diversion of technical and other resources from our other development efforts, loss of credibility with current or potential clients, harm to our reputation and exposure to liability. In addition, we rely on technologies and software supplied by third parties that may also contain undetected errors, bias, viruses, or defects that could have a material adverse effect on our business, financial condition, results of operations and cash flows.

We could be subject to reduced revenues, increased costs, liability claims, or harm to our competitive position as a result of cyberattacks, security vulnerabilities or Internet disruptions.

We rely upon information technology (“IT”) networks, cloud-based platforms, and systems to process, transmit, and store electronic information, and to support a variety of business processes, some of which are provided by third-party vendors. Cyberattacks and security threats are a risk to our business and reputation. A cyberattack, unauthorized intrusion, malicious software infiltration, network disruption or outage, corruption of data, or theft of personal or other sensitive information, could have a material adverse effect on our business operations or that of our clients, result in liability or regulatory sanction, or cause harm to our business and reputation and result in a loss in confidence in our ability to serve clients all of which could have a material adverse effect on our business. The increasing velocity of disruptive innovations involving cyberattacks, security vulnerabilities, unintended data exposure, and Internet disruptions enabled by new and emerging technologies, such as advancements in AI and machine learning, may outpace our organization's ability to compete and/or manage the risk appropriately. In addition, threat actors may seek to engage in payment-related fraud or by more frequently attempting to gain access to our systems through phishing or other means. Furthermore, security industry experts and government officials have warned about the risks of threat actors and cyberattacks targeting IT products and businesses. Because techniques used to obtain unauthorized access or sabotage systems change frequently and often are not recognized until launched against a target, we may be unable to anticipate these techniques or to implement adequate preventative measures.

Data Security and Privacy Leaks: We collect, use, and retain increasingly large amounts of personal information about our clients, employees of our clients, our employees, and other third parties, including: bank account, credit card, and social security numbers, tax return information, health care information, retirement account information, payroll information, system and network passwords, and other sensitive personal and business information. At the same time, the continued occurrence of high-profile cyber and ransomware attacks and data breaches provides evidence of an external environment increasingly hostile to information security. We may be particularly targeted for cyberattack because of the amount and type of personal and business information that we collect, use, and retain, as well as during and after periods in which we acquire other companies. Vulnerabilities, threats, and more sophisticated and targeted computer crimes pose a risk to the security of our systems and networks, and the confidentiality, availability, and integrity of our data. Furthermore, if any of our solutions contain a software vulnerability, the vulnerability may be exploited to obtain access to our data or our clients’ data.

Our service platforms enable our clients to store and process personal data on premises or, increasingly, in a cloud-based environment that we host. The security of our IT infrastructure is an important consideration in our customers’ purchasing decisions. Because the techniques used to obtain unauthorized access, disable or degrade service or sabotage systems change frequently, are increasingly more complex and sophisticated and may be difficult to detect for long periods of time, we may be unable or fail to anticipate these techniques or implement adequate or timely preventative or responsive measures. As cyber threats continue to evolve, we are focused on ensuring that our operating environments safeguard and protect personal and business information. We may be required to invest significant additional resources to comply with evolving cybersecurity regulations and to modify and enhance our information security and controls, and to investigate and remediate any security vulnerabilities. While we have security systems and IT infrastructure in place designed to detect and protect against unauthorized access to such information, including our Cyber Fusion Center, if our security measures are breached, either internally or externally, our business could be substantially harmed, and we could incur significant liabilities. Any such breach or unauthorized access could negatively affect our ability to attract new clients, cause existing clients to terminate their agreements with us, result in reputational damage, and subject us to lawsuits, regulatory fines, or other actions or liabilities which could materially and adversely affect our business and operating results. Third-parties, including vendors that provide services for our operations, could also be a source of security and reputational risk to us in the event of a failure of their own security systems and infrastructure.

Data Loss and Business Interruption: If our systems are disrupted or fail for any reason, or if our systems are infiltrated by unauthorized persons, the Company, our clients and employees of our clients could experience data loss, financial loss, harm to reputation, or significant business interruption. Hardware, applications, and services, including cloud-based services, that we develop or procure from third-party vendors may contain defects in design or other problems that could compromise the integrity and availability of our services. 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 fashion or at all. The speed to closure of significant cybersecurity incidents may be influenced by the cooperation of governmental or law enforcement agencies. We may be required to incur significant costs to protect against damage caused by disruptions or security breaches in the future. Such events may expose us to unexpected liability, litigation, regulatory investigation and penalties, loss of clients’ business, unfavorable impact to business reputation, and there could be a material adverse effect on our business and results of operations.

In the event of a catastrophe, our business continuity plan may fail, which could result in the loss of client data and adversely interrupt operations.

Our operations are dependent on our ability to protect our infrastructure against damage from catastrophe or natural disaster, unauthorized security breach, power loss, telecommunications failure, terrorist attack or act of war, public health emergency, pandemic, or other events that could have a significant disruptive effect on our operations. Climate-related weather disasters, including hurricanes, flooding, snowstorms, and severe rainstorms, could also threaten the business continuity of our operations. We have a business continuity plan in place in the event of system failure due to any of these events. Our business continuity plan has been tested in the past by circumstances of severe weather, including hurricanes, floods, snowstorms, and rainstorms and has been successful. However, these past successes are not an indicator of success in the future. If the business continuity plan is unsuccessful in a disaster recovery scenario, we could potentially lose client data or experience material adverse interruptions to our operations or delivery of services to our clients. If that were to occur, there could be a material adverse effect on our business 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. These third-party service providers include, but are not limited to, banks used to electronically transfer funds from clients to their employees, information technology vendors servicing cloud-based platforms, and other third-party providers supporting customer interactions. Failure by these service providers, or their respective outsourced 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.

We may be exposed to additional risks related to our co-employment relationship within our PEO business.

Many federal and state laws that apply to the employer-employee relationship do not specifically address the obligations and responsibilities of the “co-employment” relationship within our PEO business. State and federal positions regarding co-employment relationships are in a constant state of flux and change with varying degrees of impact on our operations. We cannot predict when changes will occur or forecast whether any future changes will be favorable or unfavorable to our operations. There is a possibility that we may be subject to liability for violations of employment or discrimination laws by our clients and acts or omissions of client employees, who may be deemed to be our agents, even if we do not participate in any such acts or violations. Although our agreements with clients provide that they will indemnify us for any liability attributable to their own or their employees’ conduct, we may not be able to effectively enforce or collect such contractual obligations. In addition, we could be subject to liabilities with respect to our employee benefit plans if it were determined that we are not the “employer” under any applicable state or federal laws. Incurring additional liabilities related to our PEO business may adversely affect our results of operations.

We may be adversely impacted by changes in health insurance and workers’ compensation rates and underlying claims trends.

Within our PEO business, we maintain health and workers’ compensation insurance covering worksite employees. We establish workers’ compensation insurance reserves to provide for the estimated costs of paying claims up to per occurrence liability limits. These reserves include estimates of certain expenses associated with processing and settling these claims. The insurance costs are impacted by claims experience and are a significant portion of our PEO costs. If we experience a sudden or unexpected increase in claims activity, or our reserves were insufficient for claims activity, our costs could increase. In addition, in the event of expiration or cancellation of existing contracts, we may not be able to secure replacement contracts on competitive terms, if at all. Also, as a co-employer in the PEO, we assume or share many of the employer-related responsibilities associated with health care reform and recent efforts by local, state and federal governments to deregulate, which may result in increased costs. Increases in costs not incorporated into service fees timely or fully could have a material adverse effect on our results of operations. Incorporating cost increases into service fees could also impact our ability to attract and retain clients.

We may not realize the expected financial or business benefits from the Paycor acquisition.

The integration of Paycor into our existing operations may present challenges aligning disparate technology platforms, operational systems, and may divert management’s attention away from day-to-day operational responsibilities to managing the integration. Compatibility issues may arise between our respective infrastructures, potentially delaying performance enhancements and straining our technical resources. Additionally, financial performance of acquired businesses may not meet pre-acquisition projections potentially affecting our consolidated results of operations, financial position and return on investment. While we have devised comprehensive strategies to address the integration complexities and maintain our strategic focus, the risks associated with unforeseen hurdles could affect our ability to achieve expected synergies and strategic growth targets.

We made and may continue to make acquisitions that involve numerous risks and uncertainties.

Acquisitions subject us to risks, including increased debt, assumption of unforeseen liabilities, and difficulties in integrating operations. Successful integration involves many challenges, including the difficulty of developing and marketing new solutions and support, our exposure to unforeseen liabilities of acquired companies, and the loss of key employees of an acquired business. The integration and conversion of our acquired operations or other future acquisitions, if any, could result in increased operating costs if the anticipated synergies of operating these businesses as one are not achieved, a loss of strategic opportunities if management is distracted by the integration process, and a loss of customers if our service levels drop during or following the integration process. In addition, an acquisition could adversely impact cash flows and/or operating results, and dilute stockholder interests, for many reasons, including charges to our income to reflect the impairment of acquired intangible assets including goodwill, interest costs and debt service requirements for any debt incurred in connection with an acquisition, and any issuance of securities in connection with an acquisition or new business venture that dilutes or lessens the rights of our current stockholders.

If the integration of any or all of our acquisitions or future acquisitions is not successful, it could have a material adverse impact on our operating results and stock price.

Financial Risks

Our clients could have insufficient funds to cover payments we made on their behalf, resulting in financial loss to us.

As part of our payroll processing solutions, we are authorized by our clients to transfer money from their accounts to fund amounts owed to their employees and various taxing authorities. It is possible that we could be held liable for such amounts in the event the client has insufficient funds to cover them. We have in the past, and may in the future, make payments on our clients’ behalf for which we may not be reimbursed, resulting in loss to us. Similarly, our ability to operate our Purchased Receivable reporting unit is dependent on the ability of our clients' clients to remit their accounts receivable to us. If a significant number of our clients are unable to cover payments we make on their behalf or we are not able to collect purchased receivable balances, our results of operations and financial condition could be materially adversely impacted.

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.

We receive interest income from investing client funds collected but not yet remitted to applicable tax or regulatory agencies or to client employees. 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 debt obligations may expose us to risks affecting the operation of our business, and our failure to address these risks could have a material adverse effect on our results of operations and financial condition.

In April 2025, we issued $4.2 billion aggregate principal amount of fixed rate corporate debt (“Corporate Bonds”). We used the net proceeds from this offering to fund our acquisition of Paycor. Refer to Note N of the Notes to Consolidated Financial Statements contained in Item 8 of this Form 10-K for further discussion of our Corporate Bonds.

Our Corporate Bonds include certain covenants which may limit our ability to create liens on our assets, enter into sale and leaseback transactions, and merge or consolidate with another entity, subject to certain exceptions, limitations and qualifications as outlined in the Corporate Bond indenture.

The Note Purchase and Guarantee Agreement (the “Agreement”) that we entered into in January 2019 in connection with our acquisition of Oasis Outsourcing Group Holdings, L.P., also contains covenants which may restrict our flexibility to operate our business. These covenants include restrictions regarding the incurrence of liens and indebtedness, substantial changes in the general nature of our business and our subsidiaries (taken as a whole), certain merger transactions, certain sales of assets and other matters, all subject to certain exceptions.

The Agreement, and the credit agreements providing for our credit facilities, also contain financial covenants, which are reviewed for compliance on a quarterly basis, that require us not to exceed a maximum leverage ratio of 3.5:1.0 and a minimum interest coverage ratio of 2.0:1.0. In addition, certain of our indebtedness may not exceed 20% of our consolidated stockholders’ equity. If we do not comply with these covenants, it could result in material adverse effects on our operating results and our financial condition.

Future acquisitions or transactions may bring us closer to the covenant thresholds previously outlined, potentially requiring further amendments to our credit facilities and debt obligations on less favorable terms.

Our ability to make scheduled debt payments or to refinance our outstanding debt obligations depends on our financial and operating performance, which is subject to prevailing economic, industry and competitive conditions and to certain financial, business, economic, and other factors that are beyond our control, including those discussed in this Risk Factors section. We may not be able to maintain a sufficient level of cash flow from operating activities to permit us to pay the principal and interest on any outstanding indebtedness. Any failure to make payments of interest and principal on our outstanding indebtedness on a timely basis would likely result in a reduction of our credit rating, which would also harm our ability to incur additional indebtedness.

If our cash flows and capital resources are insufficient to fund our debt service obligations, we may be forced to reduce or delay capital expenditures, sell assets, seek additional capital, or seek to restructure or refinance our indebtedness. Any refinancing of our indebtedness could be at higher interest rates and may require us to comply with more restrictive covenants. If we are unable to restructure or refinance our indebtedness on favorable terms, if necessary, our operating results and financial condition could be materially adversely impacted.

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

The major credit rating agencies periodically evaluate our creditworthiness and have given us a strong, investment-grade long-term debt rating. 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 high 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.

Legal, Regulatory and Political Risks

Our business, services, and financial condition may be adversely impacted by changes in government laws and regulations.

Many of our services, particularly payroll tax administration services, employee benefit plan administration services, and PEO services are designed according to government regulations that often change. Changes in regulations could affect the extent and type of benefits employers are required, or may choose, to provide employees or the amount and type of taxes employers and employees are required to pay. Such changes could reduce or eliminate the need for some of our services and substantially decrease our revenue. The addition of complex added requirements could also increase our cost of doing business.

Our business and reputation may be adversely impacted if we fail to comply with U.S. and foreign laws and regulations.

Our services are subject to various laws and regulations, including, but not limited to, the SECURE Act 2.0, data privacy regulations, and anti-money laundering rules. 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. Failure to update our services to comply with modified or new legislation in the areas of payment networks, health care reform and retirement plans as well as failure to educate and assist our clients regarding this legislation could adversely impact our business reputation and negatively impact our client base. Failure to comply with anti-money laundering laws and regulations, including but not limited to the Bank Secrecy Act of 1970 (as amended), which require us to develop and implement risk-based anti-money laundering programs, and maintain transaction records, could result in civil and criminal penalties and adversely impact our business reputation.

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 a regulatory enforcement action as well as significant civil and criminal penalties which could adversely impact our business and operations.

Our reputation, results of operations, or financial condition may be adversely impacted if we fail to comply with data privacy and AI laws and regulations.

Our solutions require the storage and transmission of proprietary and confidential information of our clients and their employees, including personal or identifying information, as well as geolocation and biometric data. Certain solutions are enhanced with the use of AI and machine learning. Our solutions are subject to various complex government laws and regulations on the federal, state, and local levels, including those governing personal privacy, AI and machine learning, as well as ethical considerations.

In the U.S., we are or may be subject to, oversight by various regulatory authorities, including but not limited to the Federal Trade Commission and Department of labor. We must also comply with such laws as the Health Insurance Portability and Accountability Act of 1996, the Family Medical Leave Act of 1993, and the Patient Protection and Affordable Care Act of 2010 (as amended). Additionally, we must also comply with federal and state labor and employment laws, and state data breach notification and data privacy laws, such as the California Consumer Privacy Act, and biometric information privacy laws all as amended. Our European operations are subject to the European Union’s General Data Privacy Regulation.

Failure to comply with such laws and regulations could result in the imposition of consent orders or civil and criminal penalties, including fines, which could damage our reputation and have an adverse effect on our results of operations or financial condition. We could be subject to litigation or reputational risk if we or our third-party providers fail to utilize data practices sufficient to safeguard proprietary, confidential, and personal or identifying information. The regulatory framework for privacy, AI, and machine learning issues is rapidly evolving and future enactment of more restrictive laws, rules, or regulations and/or future enforcement actions or investigations could have a materially adverse impact on us through increased costs or restrictions on our business and noncompliance could result in regulatory penalties and significant legal liability.

Failure to protect our intellectual property rights may harm our competitive position and litigation to protect our intellectual property rights or defend against third-party allegations of infringement may be costly.

Despite our efforts to protect our intellectual property and proprietary information, we may be unable to do so effectively in all cases. Our intellectual property could be wrongfully acquired as a result of the use of AI tools, a cyberattack, or other wrongful conduct by employees or third-parties. To the extent that our intellectual property is not protected effectively by trademarks, copyrights, patents, or other means, other parties with knowledge of our intellectual property, including former employees, may seek to exploit our intellectual property for their own and others’ advantage. Competitors may also misappropriate our trademarks, copyrights or other intellectual property rights or duplicate our technology and solutions. Any significant impairment or misappropriation of our intellectual property or proprietary information could harm our business and our brand and may adversely affect our ability to compete. Third parties may claim that we are infringing on their intellectual property rights. Additionally, there is uncertainty regarding intellectual property ownership and license rights of AI algorithms and content generated by AI and we could become subject to similar claims of infringement as we expand our use of AI. To the extent we seek to enforce or must defend our intellectual property rights with litigation, we could incur significant expenses and/or be required to pay substantial damages. We may also be obligated to indemnify our customers or vendors in connection with claims or litigation. The litigation to enforce or defend our intellectual property rights could be costly and time-consuming.

We are involved in litigation from time to time arising from the operation of our business and, as such, we could incur substantial judgments, fines, legal fees, or other costs.

We are sometimes the subject of complaints or litigation from customers, employees, or other third-parties for various actions. From time to time, we are involved in litigation involving claims related to, among other things, breach of contract, tortious conduct, and employment and labor law matters. The damages sought against us in some of these legal proceedings could be substantial. Although we maintain liability insurance for some litigation claims, if one or more of the claims were to greatly exceed our insurance coverage limits or if our insurance policies do not cover a claim, this could have a material adverse effect on our business, financial condition, results of operations, and cash flows.

General Risk Factors

Our business, results of operations, and financial condition may be impacted by macroeconomic and/or political factors of the U.S. and global economy and such impact could be materially adverse.

We and our clients are subject to the impacts related to inflationary pressure, economic instability, changes in interest rates, tariffs, potential instability of the banking environment, climate change-based obligations, and other macroeconomic and/or political events. Banking volatility may subject us and our clients to losses on uninsured funds and may make equity or debt financing more difficult to obtain, and additional equity or debt financing might not be available on reasonable terms, if at all. Additionally, our business is substantially dependent on our clients’ continued use of our solutions and support, and our results of operations will decline if our clients are no longer willing or able to use them. Our clients are sensitive to negative changes in economic conditions. If they cease operations or file for bankruptcy protection, we may not be paid for solutions we already provided, and our client base will shrink, which will lower our revenue. If under financial pressure, our clients may determine that they are no longer willing to pay for the solutions and support we provide, which would reduce our revenue. Our clients may decrease their workforce, which would decrease their demand for our solutions. Because of spending constraints on our clients and competition in the industry, we may face pricing pressure on our solutions and challenges in onboarding new clients, which would reduce revenue and ultimately impact our results of operations. Furthermore, if the third-party service providers we rely on are unable to perform their services for us and our clients, our operations could be materially disrupted, and we could face significant penalties or liabilities.

We may be adversely impacted by volatility in the political and economic environment.

Trade, monetary and fiscal policies, and political and economic conditions may substantially change, and credit markets may experience periods of constriction and variability. Additionally, instability in the banking environment may adversely affect our business. These conditions may impact our business due to lower transaction volumes or an increase in the number of clients going out of business. Further, inflation and uncertainty about tariff implementation may negatively impact our business and/or our clients' business, raise costs and reduce profitability. Current or potential clients may decide to reduce their spending on payroll and other outsourcing solutions. In addition, new business formation may be affected by an inability to obtain credit.

We invest our funds held for clients in high quality, investment-grade marketable available-for-sale (“AFS”) securities, money markets, and other cash equivalents. We also invest our corporate funds in short- to intermediate-term instruments. Funds held for clients and corporate investments are subject to general market, interest rate, credit, and liquidity risks. These risks may be exacerbated during periods of unusual financial market volatility and inflationary pressure. The interest we earn on funds held for clients and corporate investments may decrease as a result of a decline in funds available to invest or lower interest rates. In addition, during periods of volatility in the credit markets, certain types of investments may not be available to us or may become too risky for us to invest in, further reducing the interest we may earn on client funds. If we are unable to reinvest our AFS securities when they mature, our interest income earned and investment portfolio would be reduced. If we sell AFS securities to satisfy short-term funding requirements, we may recognize losses, which would further reduce the interest income earned on funds held for clients and corporate investments.

Constriction in the credit markets may impact the availability of financing, even to borrowers with the highest credit ratings. Historically, we have periodically borrowed against available credit arrangements to meet short-term liquidity needs. However, should we require additional short-term liquidity during days of large outflows of client funds, a credit constriction may limit our ability to access those funds or the flexibility to obtain them at interest rates that would be acceptable to us. Growth in customizable funding solutions offered to our clients by the purchasing of their accounts receivable through non-recourse arrangements, including funding payrolls of our clients in the temporary staffing industry, may be constricted if access to financing becomes limited. In addition, our ability to grow through significant acquisitions may be limited. See also “Item 7A. Quantitative and Qualitative Disclosures About Market Risk.” If all of these financial and economic circumstances were to remain in effect for an extended period of time, there could be a material adverse effect on our results of operations and financial condition.

We may not be able to attract and retain qualified people, which could impact the quality of our solutions and customer satisfaction.

Our success, growth, and financial results depend in part on our continuing ability to attract, retain, and motivate highly qualified and diverse personnel at all levels, including management, technical, compliance, and sales personnel. Competition for these individuals can be intense, and we may not be able to retain our key people, or attract, assimilate, or retain other highly-qualified individuals in the future, which could harm our future success.

In the event we receive negative publicity, our reputation and the value of our brand could be harmed, and clients may not use our solutions and support, which may have a material adverse effect on our business.

We are committed to good corporate citizenship, which is reflected in our company culture and core values. Disclosure of our corporate governance, responsibility, and sustainability practices, may draw negative publicity from stakeholders.

Negative publicity relating to events or activities attributed to us, our policies, our corporate employees, or others associated with us, whether or not justified, may tarnish our reputation and reduce the value of our brand. If we are unable to maintain quality HCM and employee benefit-related solutions and PEO and insurance solutions, our reputation with our clients may be harmed and the value of our brand may diminish. In addition, if our brand is negatively impacted, it may have a material adverse effect on our business, including challenges retaining clients or attracting new clients and recruiting talent and retaining employees.

PART II

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

Our common stock trades on the NASDAQ Global Select Market under the symbol “PAYX”. Dividends have historically been paid on our common stock in August, November, February, and May. The level and continuation of future dividends are dependent on our future earnings and cash flows and are subject to the discretion of our Board of Directors (the “Board”).

As of June 30, 2025, there were 7,599 holders of record of our common stock, which includes registered holders and participants in the Paychex, Inc. Dividend Reinvestment and Stock Purchase Plan. There were also 2,914 participants in the Paychex, Inc. Qualified Employee Stock Purchase Plan and 3,478 participants in the Paychex, Inc. Employee Stock Ownership Plan.

In January 2024, our Board approved a program to repurchase up to an additional $400.0 million of our common stock, with authorization expiring on May 31, 2027. The purpose of this program is to manage common stock dilution. All shares repurchased during fiscal 2025 were retired and were as follows:

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

Management’s Discussion and Analysis of Financial Condition and Results of Operations reviews the operating results of Paychex, Inc. and its wholly owned subsidiaries (“Paychex,” the “Company,” “we,” “our,” or “us”) for our fiscal year ended May 31, 2025 (“fiscal 2025” or the “fiscal year”), as compared to our fiscal year ended May 31, 2024 (“fiscal 2024”), and our financial condition as of May 31, 2025. A detailed review of our fiscal 2024 performance compared to our fiscal year ended May 31, 2023 performance and our financial condition as of May 31, 2024 is set forth in Part II, Item 7 of our Annual Report on Form 10-K (“Form 10-K”) for fiscal 2024. This review should be read in conjunction with the accompanying consolidated financial statements and the related Notes to Consolidated Financial Statements contained in Item 8 of this Form 10-K and the “Risk Factors” discussed in Item 1A of this Form 10-K. Forward-looking statements in this review are qualified by the cautionary statement under the heading “Cautionary Note Regarding Forward-Looking Statements” contained at the beginning of Part I of this Form 10-K.

Overview

We are an industry-leading human capital management (“HCM”) company delivering a full suite of technology and advisory solutions in human resources (“HR”), employee benefits, insurance, and payroll for businesses and their employees across the United States (“U.S.”) and parts of Europe.

We offer a full range of integrated HCM solutions covering the employee life cycle for businesses and their employees. Clients may choose from a breadth of solutions that also allow integration with some of the most popular HR, accounting, ERP, and point-of-sale applications on the market today.

We support our clients through our proprietary, robust, SurePayroll® SaaS-based solutions, Paychex Flex® and Paycor. Our larger clients generally have more complex payroll and employee benefit needs, though with the environment of increasing regulations, we believe the need for HR outsourcing solutions has been moving down-market. Any of our clients on Paychex Flex or Paycor can opt for the integrated suite of HCM solutions, which enables clients to choose the service and software solutions that will meet the needs of their business.

Our portfolio of technology, HR advisory, and employee benefits-related solutions is disaggregated into two categories, (1) Management Solutions and (2) professional employer organization (“PEO”) and Insurance Solutions, as discussed in Part I, Item 1 of this Form 10-K.

Our mission is to be the leading provider of HR, employee benefits, insurance, and payroll solutions by being an essential partner to businesses across the U.S. and parts of Europe. Our strategy focuses on providing industry-leading, integrated technology; growing our client base; expanding our share of wallet; driving technology innovation; and pursuing strategic acquisitions. We believe that successfully executing this strategy will lead to strong, long-term financial performance.

We maintain industry-leading margins by managing our personnel costs and expenses while continuing to invest in our business, particularly in sales and marketing and leading-edge technology. We believe these investments are critical to our success. Looking to the future, we believe that investing in our solutions, people, and digital capabilities will position us to capitalize on opportunities for long-term growth.

We closely monitor the evolving challenges and needs of our clients, and proactively aid our clients in navigating macroeconomic challenges, legislative changes, and other complexities they may face. Through our unique blend of innovative technology solutions, backed by our extensive compliance and HR expertise, we help clients more effectively hire, develop, and retain top talent in this challenging workforce environment. Our ongoing investments in our platforms have prepared us well for the demands of the current business and regulatory environments, allowing us to adapt while maintaining strong solutions and support delivery, resulting in high levels of client satisfaction and retention.

On April 14, 2025, we completed our acquisition of Paycor HCM, Inc. ("Paycor"), a leading provider of HCM, payroll and talent software. This acquisition extends our upmarket position and expands our suite of HR technology and advisory solutions. Refer to the “Liquidity and Capital Resources” section of this Item 7 for additional information.

Fiscal 2025 Business Highlights

Highlights compared to fiscal 2024 are as follows:

For further analysis of our results of operations for fiscal years 2025 and 2024, and our financial position as of May 31, 2025, refer to the tables and analysis in the “Results of Operations” and “Liquidity and Capital Resources” sections of this Item 7.

Business Outlook

Our payroll and PEO client base, including clients added through the acquisition of Paycor, was approximately 800,000 clients as of May 31, 2025 and approximately 745,000 clients as of May 31, 2024. Client retention remained high in the range of 82% to 83% of our beginning client base for both fiscal 2025 and fiscal 2024 and we have sustained high revenue retention.

We continue to increase penetration of our integrated solutions beyond payroll processing, including our HR outsourcing (ASO and PEO) and retirement solutions. The following table illustrates selected HR solutions client metrics:

In fiscal 2025, we continued to make investments in technology a priority as companies look to leverage technology solutions to maintain operations, stay connected to employees, and increase productivity. We implemented enhancements to our Paychex Flex, Paycor, and SurePayroll platforms designed to improve the client and client employee experiences from hiring and onboarding through employee retention. We also continue to focus on AI and related technology to leverage innovative technology and advanced analytics to gain deeper insights into prospects and clients regarding their behavior, preferences, and evolving needs. In fiscal 2025, we successfully implemented several additional innovative AI models that significantly improved results for Paychex and our clients.

We have further strengthened our position in the industry by serving as a source of education and information to clients, businesses of all sizes, and other interested parties. We provide free webinars, white papers, and other information on our website (www.paychex.com) to aid existing and prospective clients with the impact of regulatory changes. The Paychex Insurance Agency, Inc. website, www.paychex.com/group-health-insurance, helps small-business owners navigate the area of insurance coverage.

Results of Operations

Summary of Results of Operations for Fiscal Years:

n/m – not meaningful

Total revenue increased to $5.6 billion for fiscal 2025, reflecting an increase of 6% compared to the prior year. The changes in revenue as compared to the prior year were primarily driven by the following factors:

Excluding the acquisition of Paycor, Management Solutions revenue increased by 3% compared to the prior year.

Excluding the acquisition of Paycor, interest on funds held for clients increased by 7% compared to the prior year.

We invest in highly liquid, investment-grade fixed income securities. As of May 31, 2025, we had no exposure to high-risk or non-liquid investments. Details regarding our combined funds held for clients and corporate cash equivalents and investment portfolios are as follows:

Total expenses: Total expenses, which reflects the total combined cost of service revenue and selling, general and administrative expenses, increased 8% to $3.4 billion compared to the prior year. The following table summarizes the components of total expenses:

n/m - not meaningful

The changes in total expenses as compared to the prior year were primarily driven by the following factors:

Excluding the acquisition of Paycor and the prior year period cost optimization initiatives noted above, total expenses increased approximately 2% compared to the prior year.

Operating income: Fiscal 2025 operating income was $2.2 billion, an increase of 2% compared to fiscal 2024. Adjusted operating income(1) of $2.4 billion, which excludes the acquisition related costs and cost optimization initiatives noted above, reflects an increase of 7%. Operating income for fiscal 2025 was impacted by the acquisition of Paycor and the expiration of the ERTC program.

Operating margin (operating income as a percentage of total revenue) and adjusted operating margin(1) (adjusted operating income(1) as a percentage of total revenue) were as follows:

Interest expense: Interest expense increased $68.1 million to $105.4 million in fiscal 2025, primarily due to the issuance of incremental debt to finance the acquisition of Paycor and acquisition-related costs included in interest expense.

Other income, net: Other income, net decreased 9% to $73.6 million in fiscal 2025, as a result of lower average interest rates earned on our corporate investments, partially offset by higher average investment balances.

Income taxes: Our effective income tax rate was 23.8% for fiscal 2025 and 2024. The effective income tax rates in both periods were affected by the recognition of discrete tax impacts related to employee stock-based compensation payments. Refer to Note L of the Notes to Consolidated Financial Statements contained in Item 8 of this Form 10-K for additional disclosures on income taxes.

Net income and diluted earnings per share: Net income was $1.7 billion for fiscal 2025 and 2024. Diluted earnings per share was $4.58 per diluted share for fiscal 2025 and $4.67 per diluted share for fiscal 2024. Refer to Note C of the Notes to Consolidated Financial Statements contained in Item 8 of this Form 10-K for information on dilutive shares outstanding.

Adjusted net income(1) was $1.8 billion and $1.7 billion for fiscal 2025 and 2024, respectively, reflecting an increase of 5%. Adjusted diluted earnings per share(1) was $4.98 per diluted share and $4.72 per diluted share for fiscal 2025 and fiscal 2024, respectively, reflecting an increase of 6%.

Non-GAAP Financial Measures: Adjusted operating income, adjusted operating margin, adjusted net income, adjusted diluted earnings per share, earnings before interest, taxes, depreciation, and amortization (“EBITDA”), and adjusted EBITDA are summarized as follows:

In addition to reporting operating income, operating margin, net income and diluted earnings per share, which are U.S. GAAP measures, we present adjusted operating income, adjusted operating margin, adjusted net income, adjusted diluted earnings per share, EBITDA and adjusted EBITDA, which are non-GAAP measures. We believe these additional measures are indicators of the performance of our core business operations period over period. Adjusted operating income, adjusted operating margin, adjusted net income, adjusted diluted earnings per share, EBITDA and adjusted EBITDA, are not calculated through the application of U.S. GAAP and are not required forms of disclosure by the Securities and Exchange Commission (“SEC”). As such, they should not be considered a substitute for the U.S. GAAP measures of operating income, operating margin, net income, and diluted earnings per share, and, therefore, they should not be used in isolation but in conjunction with the U.S. GAAP measures. The use of any non-GAAP measure may produce results that vary from the U.S. GAAP measure and may not be comparable to a similarly defined non-GAAP measure used by other companies.

Liquidity and Capital Resources

Our financial position as of May 31, 2025 remained strong with cash, restricted cash, and total corporate investments of $1.7 billion. Short-term borrowings of $18.6 million and long-term borrowings of $5.0 billion were outstanding as of May 31, 2025. Our unused capacity under our unsecured credit facilities was $2.0 billion as of May 31, 2025. Our primary source of cash is our ongoing operations, which was $1.9 billion for fiscal 2025. Our positive cash flows have allowed us to support our business, and pay dividends. We currently anticipate that corporate cash, corporate restricted cash, and total corporate investments as of May 31, 2025, along with projected operating cash flows and available short-term financing, will support our business operations, capital purchases, primarily investments in our technology solutions, share repurchases, dividend payments, acquisitions and debt service for the foreseeable future.

For client funds liquidity, we have the ability to borrow on our unsecured credit facilities or use corporate liquidity when necessary to meet short-term funding needs related to client fund obligations. Historically, we have borrowed, typically on an overnight basis, to settle short-term client fund obligations, rather than liquidate previously collected client funds invested in our long-term AFS portfolio. We believe that our investments in an unrealized loss position as of May 31, 2025 were not impaired due to increased credit risk or other valuation concerns, nor has any event occurred subsequent to that date to indicate any change in our assessment. We do not intend to sell these investments until recovery of their amortized cost basis or maturity and further believe that it is not more-than-likely that we would be required to sell these investments prior to that time.

Financing

Short-term financing: We maintain committed and unsecured credit facilities and irrevocable letters of credit as part of our normal and recurring business operations. The purpose of these credit facilities is to meet short-term funding requirements, finance working capital needs, and for general corporate purposes. We typically borrow on an overnight or short-term basis on our credit facilities. Refer to Note M of the Notes to Consolidated Financial Statements contained in Item 8 of this Form 10-K for further discussion on our credit facilities.
