Part I

CORPORATE BACKGROUND

General

In 1949, our founders established ADP to shape the world of work with a simple, innovative idea: help clients focus on their business by solving their payroll challenges. Today, we are one of the world’s leading global technology companies providing comprehensive cloud-based human capital management (HCM) solutions that unite HR, payroll, talent, time, tax and benefits administration. Our unmatched experience, expertise, insights and cutting-edge technology have transformed HCM from an administrative challenge to a strategic business advantage. Tailored to meet the needs of businesses of all sizes, we help them work smarter today so they can have more success tomorrow. We serve over 1 million clients and pay over 41 million workers in 140 countries and territories. Our common stock is listed on the NASDAQ Global Select Market® under the symbol “ADP.”

When we refer to “we,” “us,” “our,” “ADP,” or the “Company” in this Annual Report on Form 10-K, we mean Automatic Data Processing, Inc. and its consolidated subsidiaries.

BUSINESS OVERVIEW

ADP’s Mission

Our mission is to power organizations with insightful Human Capital Management (HCM) solutions that meet the changing needs of our clients and their workers.

Data, digital technology, artificial intelligence, globalization, new business models and other significant events and disruptions continuously reshape the way people work. Our HCM technology, industry and compliance expertise and data insights deliver measurable results and peace-of-mind, and contribute to an engaged, productive workforce. Our leading technology and commitment to service excellence are at the core of our relationship with each one of our clients, whether it's a small, mid-sized or large organization operating in one or multiple countries around the world. We are always designing better ways to work through cutting-edge products, premium services and exceptional experiences that enable people to reach their full potential.

ADP's Business Pillars

Our business is organized around three pillars which represent our core growth areas.

U.S. HCM Solutions: In the United States, we provide cloud-based HCM software with supporting service and expertise that assists employers of all types and sizes in managing the entire worker spectrum and employment cycle – from full-time to freelancer and from hire to retire.

U.S. HR Outsourcing (HRO) Solutions: In the United States, we offer comprehensive HRO solutions in which we provide complete management solutions for HR

administration, payroll administration, talent management, employee benefits, benefits administration, employer liability management, and other HCM and employee benefits functions.

Global Solutions: We offer international HCM and HRO solutions, comprised of both local, in-country solutions and cloud-based multi-country solutions, to clients wherever they do business around the world.

ADP’s Strategy

Our business strategy has three key priorities:

With a large and growing addressable market, we are focused on our core growth areas and further enhancing our market position by executing on our Strategy:

• Lead with Best-in-Class HCM Technology.** We design and develop world-class HCM platforms that simplify work and utilize enabling technologies like artificial intelligence and modern cloud architecture. We aim to solve the needs of our clients and their workers today by making HCM transactions effortless and compliant, while anticipating their needs of tomorrow by incorporating valuable data insights and guidance into our solutions to help them better understand their workforce and how they compare to industry peers, and position them to make better decisions.

• Provide Unmatched Expertise and Outsourcing Solutions.** Our clients look to us as a source of expertise to understand key HR trends and best practices, employment and related legislation, and to offer thoughtful strategies to utilize HCM technology to achieve their business objectives and support their workforce. Many of our clients also look to us to take on responsibility for a portion or all of their HCM workflow via one of our HRO solutions. We intend to continue to build on our deep expertise and make it readily available to our clients through a variety of channels, ranging from traditional call and chat options to self-guided and AI-powered options. We will continue to leverage our decades of experience, our significant data insights, and investments in AI and other enabling

technologies to help our clients and their workers navigate the ever-changing world of work.

• Benefit our Clients with Our Global Scale.** Our clients benefit from our unmatched global footprint and scale in the HCM industry. We will continue to build on these strengths to further improve our client experience, and to add to our global footprint to further meet our clients where they choose to do business and address their needs for a distributed and flexible workforce. We intend to build more relationships with partners, such as through the ADP Marketplace, in order to provide clients with seamless integrations and customizations that simplify their HR processes and help them meet their needs. And we will grow our sales organization and continue to invest in best-in-class sales technology to not only make the purchase experience seamless but to also empower our sellers to provide the deep expertise and insights our clients, partners and influencers require to ensure they have the right HCM solutions to help them achieve their objectives and make a meaningful impact for their employees.

As we continue to invest in and execute on our Strategy, we intend to continue to exceed the expectations of our clients and enable them and their people to reach their full potential.

Innovation at ADP

Innovation is in our DNA. For over 70 years, we have proven that actively listening and responding to what clients and their employees need and want keeps the world of work progressing forward. We pioneered HCM automation, HCM in the cloud, mobile HCM and a digital HCM marketplace. This spirit of innovation remains a steady guide as we continue to listen and respond to emerging needs. As the business, data and digital technology landscape continues to rapidly evolve, what “work” means, how and where it gets done, and how workers are paid is changing as well.

Leveraging the power of data, we innovate by anticipating the future of work, the future of HCM and the future of pay to help our clients transform their businesses, simplify work and empower their workers.

The size and breadth of ADP gives us a unique opportunity, especially in the era of data and data-driven products, to test innovative ideas, validate hypotheses and refine solutions before we bring them to the market. This happens through our “client-zero” program, which forges a direct connection point between our internal HR practitioners and our technologists. A key area of focus is using data and feedback from front-line practitioners to build products that improve the employee experience and make HR technology more intentional and in the moment. By innovating with a client-centric mindset, we continue to transform work.

In today’s world of work, people-data has never been more important. It gives companies the information they need to identify the depth and scope of people issues, anticipate and solve challenges, foster connections across their workforce and drive business outcomes. Sitting at the center of workforce data, we leverage the unrivaled scale, breadth, and depth of our data to provide the insights businesses need to create a better world of work. Our data is also the basis for our renowned ADP National Employment Report, which the ADP Research Institute (ADPRI) and the Stanford Digital Economy Lab recently retooled to provide a more robust, independent high-frequency view of the labor market and trajectory of economic growth in the United States.

The scale and scope of our client base provides us an unrivaled HCM dataset, and we are focused on converting our data advantage into our client’s data advantage. We are doing this by differentiating our HCM solutions and providing our clients with insights that can help drive better decisions, and by continuing to identify and pursue new and additional data-as-a-service opportunities. We are leading this innovation effort with ADP® DataCloud, our award-winning machine learning (ML) and workforce analytics platform which is the largest private repository of payroll information available. DataCloud analyzes aggregated, anonymized and timely HCM and compensation data from more than 1 million organizations across the U.S., powering solutions that provide clients with in-depth workforce and business insights that enable critical HR decisions.

Artificial intelligence (AI) drives many of the key features of ADP’s data products. In the U.S., ADP DataCloud's Skills Graph, our proprietary data structure, is based on more than 43 million employee records, 95 million resumes and 9 million job postings across more than 20 industries and 500 geographic areas, and uses large language models to extract, align and normalize key information such as skills, job titles and levels, education and qualifications from non-structured data and infers missing skills and qualifications from context. Skills Graph powers ADP’s Candidate Profile Relevancy tool to help score, assess and predict candidates who are the best fit for a job opening and is designed to minimize the introduction of bias by, among other things, focusing on the skills, education, and experience of an applicant. Skills Graph also powers our new Organizational Benchmarking Dashboard, which enables companies to decide how best to deploy their workers by comparing organizational metrics like headcount, labor costs and turnover against other similar businesses, as well as Talent Market Insights where organizations can explore jobs and locations to understand talent availability, skills, wages, turnover and time to fill. ADP’s Model-Based Benchmarks, powered by Skills Graph, also extend benchmarks to include compensation for up to 160 million workers. Model-Based Benchmarks are driven by a set of deep learning models that extract

patterns and knowledge from millions of payroll records and job profiles to provide accurate information that reflects the reality of the position being researched. We offer similar tools to clients outside the United States, including through our ADP GlobalView® and ADP iHCM solutions.

We are also using AI to respond to the needs of HR practitioners. ADP’s data-driven Intelligent Self-Service solution uses predictive analytics and machine learning to proactively address common employee HR challenges before the need to contact their HR departments arises, freeing HR practitioners to focus on higher value initiatives. It was named a “Top HR Product” at the 2022 HR Technology Conference, marking the 8th consecutive year we have received this award for continued product innovation.

ADP’s Pay Equity Storyboard combines analytics and benchmarking to help employers better understand potential pay gaps and provide them with real, up-to-date, aggregated and anonymized market data to understand how their compensation for a particular job compares to other similar employers. Insights powered by DataCloud are particularly important with respect to diversity, equity and inclusion (DEI) and, as part of our commitment to DEI, we introduced the first-of-its-kind, award-winning DEI benchmark to help companies assess DEI gaps, track their progress and achieve their goals, bolstering ADP’s suite of DEI offerings. It also earned acclaim in Fast Company’s first-ever list of the “Next Big Things in Tech,” which

highlights tech breakthroughs that promise to define the future of their industries.

In harnessing the power of data through ML, ADP recognizes the importance of accountability, transparency, privacy, explainability and governance, and in furtherance of those goals has established an active AI & Data Ethics Committee, comprised of both industry leaders and ADP experts, which advises on emerging industry trends and concerns and provides guidance with respect to compliance with the principles that ADP should follow while developing products, systems and applications that involve AI, ML and data.

As we continue to explore the potential that new technologies like generative AI can provide as we design and develop innovative solutions, we understand the great responsibility we have to approach these innovations in a way that is ethical, secure, and compliant for our business and the clients and workers we serve around the world. This led to our establishment of an interdisciplinary working group across ADP to determine governance for use cases and adoption of a set of principles and processes to govern the use of these newer technologies, including operational monitoring of recommendations made by AI/ML technologies.

Built to be as dynamic as the world of work today, our next-gen platforms are designed for adaptability. Built from the ground up to be cloud-native, global, scalable and secure, our next-gen platforms are designed to provide our clients with the flexibility they need to address today’s and tomorrow’s workplace challenges, and to personalize the experience based on their needs. Built for dynamic teams, our next-gen HCM platform provides our clients with visibility into where work happens rather than into rigid organizational hierarchies and worker types. And, by deploying low-code applications, clients can easily tailor the solution to their needs.

Our next-gen payroll platform is a global solution that supports workers of all types and enables real-time, transparent, continuous payroll calculations. This next-gen payroll platform also unlocks flexible pay choices for our clients so they can provide the best pay experience for their workers. As the regulatory environment rapidly changes, making it harder for companies to navigate the complexities of payroll, our next-gen payroll platform’s built-in compliance capabilities enable our clients to focus on managing their business.

Additionally, we launched the “Roll™ by ADP” mobile-first solution – reimagining how small businesses do payroll. This groundbreaking payroll solution utilizes an AI-powered chat interface to turn traditional payroll management into an intuitive conversation that can complete payroll in under a minute. Leveraging ADP’s long-standing payroll expertise and data security, small

business owners can download and self-purchase Roll and run payroll anywhere, anytime, quickly and compliantly, with no experience or training needed. The conversational experience runs off simple chat prompts such as “Run my payroll,” offering a frictionless experience that also allows clients to confidently handle compliance matters like tax filing and deposits.

Our innovative Wisely® payment and financial wellness offering includes a suite of personalized banking-alternative solutions designed to give employees fast and flexible choices to access their pay and other sources of income. Wisely® Pay is a network-branded paycard with a digital account, through which employees can access their pay, make purchases online and in store, deposit checks, load additional funds onto the card, and transfer funds to a bank account in the United States. Wisely also enables advanced capabilities and innovative features such as Earned Wage Access (EWA), automatic savings options, cash back rewards and bill pay that help employees take even more control of their finances. Wisely® Direct, a network-branded general purpose reloadable card that comes with a digital account, provides similar features and functionality but is offered directly to consumers. Our digital card offerings are banking alternatives that afford

financial wellness tools designed to help members realize a better financial path forward.

‘Always Designing for People’ isn’t just a tag line – innovation is also about putting our clients first by giving them and their workers a faster, smarter and easier user experience (UX) that was designed with and for them. With a modern look and feel based on our new design system, our new UX is powered by data and ML and provides intuitive workflows that are available when and where our clients and their workers need it. We are investing in UX alignment and simplification across our strategic products and solutions, with new UX releases for RUN Powered by ADP®, MyADP, ADP® Mobile Solutions and, most recently, ADP Workforce Now®.

In addition, our ADP Mobile app simplifies how work gets done by enabling clients to process their payroll anywhere, and giving millions of their employees worldwide convenient access to their payroll and HR information in 32 languages. We expanded employee self-service via our app by incorporating ML-based recommendations for employees to better find information, correct missing information, and complete tasks more efficiently.

Reportable Segments

Our two reportable business segments are Employer Services and Professional Employer Organization (“PEO”), and are based on the way that management reviews the performance of, and makes decisions about, our business. For financial data by segment and by geographic area, see Note 14 to the “Consolidated Financial Statements” contained in this Annual Report on Form 10-K.

Employer Services. Our Employer Services segment serves clients ranging from single-employee small businesses to large enterprises with tens of thousands of employees around the world, offering a comprehensive range of technology-based HCM solutions, including our strategic, cloud-based platforms, and HRO (other than PEO) solutions. These solutions address critical client needs and include: Payroll Services, Benefits Administration, Talent Management, HR Management, Workforce Management, Compliance Services, Insurance Services and Retirement Services.

Professional Employer Organization. Our PEO business, called ADP TotalSource®, provides clients with comprehensive employment administration outsourcing solutions through a relationship in which employees who work for a client (referred to as “worksite employees”) are co-employed by us and the client.

ADP TotalSource clients are able to offer their employees services and benefits on par with those of much larger enterprises, without the need to staff a full HR department. With our cloud-based HCM software at the core, we serve more than 16,000 clients and

We give clients access to a patented approach to help them target the best benefit plan offerings for their employees. They can compare plan options and make more educated decisions about what plan offering is best for their company and budget. In addition, ADP TotalSource integrates with our award-winning ADP Marketplace to further tailor offerings, such as helping employees pay off student loans with payroll contributions and integrating a client’s U.S. PEO population with its global workforce’s HR system of record.

• Protection and Compliance: ADP TotalSource HR experts help clients manage the risks of being an employer by advising how to handle properly a range of issues – from HR and safety compliance to employee-relations.

MARKETS AND SALES

Our HCM solutions are offered in 140 countries and territories across North America, Latin America, Europe, Asia and Africa. The most material markets for HCM Solutions, Global Solutions and HRO Solutions (other than PEO) are the United States, Canada and Europe. In each market, we have both country-specific solutions and multi-country solutions, for employers of all sizes and complexities. The major components of our offerings throughout these geographies are payroll, HR outsourcing and time and attendance management. In addition, we offer wage and tax collection and/or remittance services in the United States, Canada, the United Kingdom, Australia, India and China. Our PEO business offers services exclusively in the United States.

We market our solutions primarily through our direct sales force. We also market HCM Solutions, Global Solutions and HRO Solutions through indirect sales channels, such as marketing relationships with certified public accountants and banks, among others. None of our major business units has a single homogeneous client base or market. While concentrations of clients exist in specific industries, no one client, industry or industry group is material to our overall revenues. We are a leader in each of our major service

offerings and do not believe any of our major services or business units is subject to unique market risk.

COMPETITION

The industries in which we operate are highly competitive. We know of no reliable statistics by which we can determine the number of our competitors, but we believe that we are one of the largest providers of HCM solutions in the world. HCM Solutions, Global Solutions and HRO Solutions (other than PEO) compete with other business outsourcing companies, companies providing ERP services, providers of cloud-based HCM solutions and financial institutions. Our PEO business competes with other PEOs providing similar services, as well as business outsourcing companies, companies providing ERP services and providers of cloud-based HCM solutions. Other competitive factors include a company’s in-house function, whereby a company installs and operates its own HCM system.

Competition for business outsourcing solutions is primarily based on product and service quality, reputation, ease of use and accessibility of technology, breadth of offerings, and price. We believe that we are competitive in each of these areas and that our leading-edge technology (together with our data) and commitment to service excellence, distinguishes us from our competitors.

INDUSTRY REGULATION

Our business is subject to a wide range of complex U.S. and foreign laws and regulations. In addition, many of our solutions are designed to assist clients with their compliance with certain U.S. and foreign laws and regulations that apply to them. We have, and continue to enhance, compliance programs and policies to monitor and address the legal and regulatory requirements applicable to our operations and client solutions, including dedicated compliance personnel and training programs.

As one of the world’s largest providers of HCM solutions, our systems contain a significant amount of sensitive data

related to clients, employees of our clients, vendors and our employees. We are, therefore, subject to compliance obligations under federal, state and foreign privacy, data protection, artificial intelligence (AI) and cybersecurity-related laws, including federal, state and foreign security breach notification laws with respect to both client employee data and our own employee data. The changing nature of these comprehensive laws in the United States, Europe and elsewhere, including the European Union’s (the “EU”) General Data Protection Regulation (the “GDPR”) and the California Privacy Rights Act of 2020 (the “CPRA”), impact our processing of personal information of our employees and on behalf of our clients. The GDPR imposes strict and comprehensive requirements on us as both a data controller and a data processor. As part of our overall data protection compliance program, including with respect to data protection laws in the EU, we are one of the few companies in the world to have implemented Binding Corporate Rules (“BCRs”). Compliance with our BCRs permits us to process and transfer personal data across borders in accordance with the GDPR and other data protection laws in the EU. The CPRA requires companies to provide data disclosure, access, deletion and opt-out rights to consumers in California. In the area of artificial intelligence, some states and localities in the U.S. have proposed or already enacted legislation and proposals are pending in the European Union and elsewhere that would impose obligations on how we develop and market AI-based products and solutions. Additionally, self-regulatory frameworks like the National Institute of Standards and Technology AI Risk Management Framework are being promulgated and adherence to these may become an industry standard or client expectation. In the United States, the Health Insurance Portability and Accountability Act of 1996 applies to our insurance services businesses and ADP TotalSource.

As part of our payroll and payroll tax management services, we move client funds to taxing authorities, our clients’ employees and other payees via electronic transfer, direct deposit, prepaid access and ADPCheck. In 2019, the Office of the Comptroller of Currency (the “OCC”) authorized us to open ADP Trust Company, National Association (the “ADP Trust Bank”), via a national trust bank charter pursuant to the National Bank Act. The ADP Trust Bank is the sole trustee of ADP Client Trust, our grantor trust which holds U.S. client funds, and is responsible for the oversight and management of those client funds. The ADP Trust Bank, and all of its fiduciary activities including the U.S. money movement it oversees and manages via ADP Client Trust, is subject to comprehensive ongoing oversight and regulation by the OCC. In addition, our U.S. money movement managed by the ADP Trust Bank and our U.S. prepaid access offering are subject to the anti-money laundering and reporting provisions of The Bank Secrecy Act of 1970, as amended by the USA PATRIOT Act of 2001 (the “BSA”). Elements

of our money movement activities outside of the United States are subject to licensing and similar anti-money laundering and reporting laws and requirements in certain countries in which we provide such services. Our employee background screening services business offers background checking services that are subject to the Fair Credit Reporting Act. ADP TotalSource is subject to various state licensing requirements and, as a Certified PEO, maintains certifications with the Internal Revenue Service. Because ADP TotalSource is a co-employer with respect to its clients’ worksite employees, we may be subject to certain obligations and responsibilities of an employer under federal and state tax, insurance and employment laws, including worksite employee payroll obligations and with respect to claimed employee retention and other tax credits. ADP Strategic Plan Services, LLC, our registered investment adviser, provides certain investment management and advisory services to retirement plan administrators under a heightened “fiduciary” standard and is regulated by the SEC and the U.S. Department of Labor. ADP Broker-Dealer, Inc., which supports our Retirement Services business, is a registered broker-dealer regulated by the SEC and the Financial Industry Regulatory Authority (FINRA).

Our current and future offerings in the payments and/or consumer space may also subject us to additional laws and regulations, which could also require corresponding compliance programs and policies and dedicated resources.

In addition, many of our businesses offer solutions that assist our clients in complying with certain U.S. and foreign laws and regulations that apply to them. Although these laws and regulations apply to our clients and not to ADP, changes in such laws or regulations may affect our operations, products and services. For example, our payroll services are designed to facilitate compliance with state laws and regulations applicable to the payment of wages. In addition, our HCM solutions help clients manage their compliance with certain requirements of the Affordable Care Act in the United States. Similarly, our Tax Credit Services business, which helps clients in the United States take advantage of tax credit opportunities in connection with the hiring of new employees and certain other activities, is based on federal, state or local tax laws and regulations allowing for tax credits, which are subject to renewal, amendment or rescission.

We believe that key components of our compliance programs provide real competitive differentiators. For instance, our BCRs have enabled ADP to apply a global standard of data protection, simplifying data transfer processes and assisting our clients in meeting the demanding standards of data protection expected in Europe – a solution that most competitors cannot provide. Similarly, the ADP Client Trust and ADP Trust Bank provide client funds with a level of protection that most competitors cannot offer. We continue to expand our

approach to compliance and are adopting “Compliance by design” as a tenet that prioritizes compliance in designing and developing new solutions to support our clients.

The foregoing description does not include an exhaustive list of the laws and regulations governing or impacting our business. See the discussion contained in the “Risk Factors” section in Part I, Item 1A of this Annual Report on Form 10-K for information regarding changes in laws and regulations that could have a materially adverse effect on our reputation, results of operations or financial condition or have other adverse consequences.

CLIENTS AND CLIENT CONTRACTS

We provide services to more than 1 million clients. In fiscal 2023, no single client or group of affiliated clients accounted for revenues in excess of 2% of our annual consolidated revenues.

We are continuously in the process of performing implementation services for new clients. Depending on the service agreement and/or the size of the client, the installation or conversion period for new clients can vary from a short period of time for a small Employer Services client (as little as 24 hours) to a longer period for a large Employer Services client with multiple deliverables (generally six to nine months). In some cases, based on a client's timeline, the period may exceed two years for a large, multi-country GlobalView client or other large, multi-phase implementation. Although we monitor sales that have not yet been installed, we do not view this metric as material to an understanding of our overall business in light of the recurring nature of our business. This metric is not a reported number, but it is used by management as a planning tool to allocate resources needed to install services, and as a means of assessing our performance against the expectations of our clients. In addition, some of our products and services are sold under longer-term contracts with initial terms ranging from two to seven years. However, this anticipated future revenue under contract is not a significant portion of our expected future revenue, is not a meaningful indicator of our future performance and is not material to management's estimate of our future revenue.

Our business is typically characterized by long-term client relationships that result in recurring revenue. Our services are provided under written price quotations or service agreements having varying terms and conditions. No one price quotation or service agreement is material to us. Based on our retention levels in fiscal 2023, our client retention is estimated at approximately 13 years in Employer Services, and approximately 6 years in PEO.

PRODUCT DEVELOPMENT

We continually upgrade, enhance, and expand our solutions and services. In general, new solutions and services supplement rather than replace our existing solutions and services and, given our recurring revenue model, do not have a material and immediate effect on our revenues. We believe that our strategic solutions and services have significant remaining life cycles.

SYSTEMS DEVELOPMENT AND PROGRAMMING

During the fiscal years ended June 30, 2023, 2022 and 2021, we invested approximately $1.195 billion, $1.210 billion and $1.016 billion, respectively, in systems development and programming. These investments include expenses for activities such as the development of new products, maintenance expenses associated with our existing technologies, purchases of new software and software licenses, and additions to software resulting from business combinations.

LICENSES

We are the licensee under a number of agreements for computer programs and databases. Our business is not dependent upon a single license or group of licenses. Third-party licenses, patents, trademarks, and franchises are not material to our business as a whole.

OUR HCM STRATEGY

Our Human Capital Management (HCM) strategy is simple, our people are one of our most valuable assets and we are committed to valuing, developing and engaging them.

Our Chief Human Resources Officer (CHRO), together with our Executive Leadership Team, manages our HCM strategy and related programs and initiatives, as well as our talent strategy. Our CHRO, along with our CEO, as

appropriate, regularly updates and supports our Compensation and Management Development Committee of the Board (“CMDC”) as well as the Board of Directors on HCM matters, including culture, engagement, and diversity, equity, inclusion and belonging. The CMDC is responsible for these matters, as well as our executive compensation program, management succession planning and talent development, and company-wide equity-based plans.

Our Associates and Demographics

As of June 30, 2023, our global team of associates consisted of approximately 63,000 persons. We track certain gender and racial demographics of our workforce and share them in our annual Global Corporate Social Responsibility (“CSR”) Report, which is available on our website. Nothing in our CSR Report shall be deemed incorporated by reference into this Annual Report on Form 10-K.

Our Culture and Values

More than 70 years ago, our founders established the values that guide us today.

These values have helped shape our one-of-a-kind culture, which embraces diversity, equity, inclusiveness and belonging.

Our long-term business success is closely linked to our commitment to creating an environment in which our associates thrive, and that means we have to listen to and engage our associates. We conduct an annual culture survey, myVoice, where our associates can share their opinions on important topics, including client service, diversity, social responsibility, ethics, innovation and leadership. Along with many of our world-class clients, we leverage our innovative StandOut® powered by ADP platform, to drive talent engagement, performance management and activation. We issue quarterly global

StandOut® Engagement Pulse® and Performance Pulse® surveys to ensure that all associates can share with their leaders how they feel about their work and their colleagues, and for us to get a snapshot of engagement across the globe.

The strength of our ADP team comes from what each one of us offers each other, our clients and our community. Through our myMoment Recognition Program, we give our associates the opportunity to recognize and celebrate each other when they demonstrate our values, drive our goals and go above and beyond in contributing to our collective success. Our global ADP Cares program, which is funded by the Company, the ADP Foundation and our generous associates, helps members of our team get through difficult, unforeseen events such as natural disasters and major illnesses. We also proudly support our associates that give back to our communities through paid volunteer time off and our donation matching program.

Diversity, equity and inclusion are a cornerstone of our one-of-a-kind culture. We value diverse perspectives and believe that our associates and their best ideas thrive in a diverse and inclusive environment. We strive to reflect the diversity of the communities and clients we serve and are firmly focused on ensuring that all our associates are welcomed and enjoy a deep sense of belonging.

We have a number of initiatives to strengthen and further cultivate our inclusive and diverse culture, starting with our Talent Task Force for all of our people leaders, which includes diversity goals for our senior leaders that are tied to their compensation as an incentive to diversify our leadership ranks. Our Workforce Diversity Initiative uses data analysis to identify and focus on opportunities to increase the number of underrepresented associates in our workforce to better reflect the communities we serve. Our voluntary business resource groups (BRGs), which cover a broad array of diverse associates that share common interests and experiences, make us stronger by promoting diversity and cultural awareness, accelerating associate engagement, retention and career development, helping build relationships with diverse markets in our communities, and promoting the conservation and restoration of natural resources.

We have undertaken and implemented several initiatives that underpin our culture, values and talent practices, including:

• Continuing to eliminate a college degree requirement to expand the applicant pool for non-specialized roles, such as those in our sales, service and implementation and technology organizations;

• Launching ADP’s Impact Council, activating top executives to align their business unit practices and

outcomes with our diversity, equity and inclusion strategy; and

• Establishing partnerships with the National Black MBA Association, the United Negro College Fund, Prospanica, the Anita Borg Institute for Women and Technology and Disability:IN to further diversify our talent pipeline and educate and develop their members.

In addition, we are deeply committed to fair and equitable pay, which is critical to creating a diverse, inclusive and engaging culture. We make pay decisions based on skills, job-related experience, the market value of the job and performance, and in the U.S. and Canada do not ask candidates for prior pay history, whether or not we are required to do so.

Our commitment to building a better world of work and creating a workplace where everyone can thrive has led to recognition across the globe, including Fortune’s World’s Most Admired Companies (17 consecutive years); Best Place to Work for LGBTQ+ Equality (13 consecutive perfect scores on the Human Rights Campaign Foundation’s Corporate Equality Index); DiversityInc Top 50 Companies for Diversity; Seramount’s Best Companies. for Multicultural Women; Barron’s 100 Most Sustainable Companies; and Newsweek’s America’s Most Responsible Companies.

Our Talent Strategy

Our talent strategy is simple – we aim to attract, develop and retain ambitious, passionate and overall top talent by offering a place where our people can grow their careers, challenge themselves, share generously, take risks, and create positive change. This has allowed us to be consistently recognized by esteemed organizations as an employer of choice year after year.

We invest in our team members so that they have the skills necessary to succeed and grow their careers. The ADP talent journey begins with an innovative, engaging and comprehensive onboarding process followed by extensive

training and mentorship. Thereafter, our associates can access a wide range of professional and functional skills training to further continue and enhance performance and career development. Our professional skills program provides on-demand and self-paced learning paths on key topics such as business acumen, client service, time management, teamwork and collaboration, communication and career management. Our leadership program is designed to help leaders build self-awareness, cultivate strong internal relationships, establish a leadership model that is unique to their strengths and achieve better decision-making using systems thinking.

Our Benefits and Health and Wellness Programs

The wide range of benefits and health and wellness programs we offer contribute to an environment where all our associates add to our success. Our associates receive a competitive benefits package, intended to help them enjoy physical, emotional and financial well-being and be productive members of their teams. While exact benefits vary by associate and region, they typically include health care coverage, a 401(k) plan with company matching contributions for U.S. associates, life insurance, paid time off and tuition reimbursement. We particularly emphasize benefits that support individual and family needs (parental leave, adoption/fertility benefits and caregiver support), and constantly update our programs according to our associates’ needs.

We offer physical and mental wellness programs that help our team pursue a healthy lifestyle and reduce absenteeism and lost time due to injuries. Our efforts include a company-wide health and safety manual and website, safety education and training, and a wellness program that rewards associates for completing wellness activities. Physical and mental health initiatives vary across regions, but can include personal health checks, nutrition and fitness expert visits offering free consultation and programs, employee mental wellness assistance programs, free counseling and mental health therapy assistance for associates, and mindfulness classes.

Our businesses routinely encounter and address risks, some of which may cause our future results to be different than we currently anticipate. The risk factors described below represent our current view of some of the most important risks facing our businesses and are important to understanding our business. The following information should be read in conjunction with Management’s Discussion and Analysis of Financial Condition and Results of Operations, Quantitative and Qualitative Disclosures About Market Risk and the consolidated financial statements and related notes included in this Annual Report on Form 10-K. This discussion includes a number of forward-looking statements. You should refer to the description of the qualifications and limitations on forward-looking statements in the first paragraph under Management’s Discussion and Analysis of Financial Condition and Results of Operations included in this Annual Report on Form 10-K. See "Item 1. Business—Competition" of this Form 10-K for a discussion of the competitive environment in the markets in which we operate. Many risks affect more than one category, and the risks are not in order of significance or probability of occurrence because they have been grouped by categories. The risks described below are not the only risks we face and the occurrence of any of the following risks or other risks not presently known to us or that we currently believe to be immaterial could have a materially adverse effect on our business, results of operations, financial condition or reputation.

LEGAL AND COMPLIANCE RISKS

Failure to comply with, compliance with or changes in, laws and regulations applicable to our businesses could have a materially adverse effect on our reputation, results of operations or financial condition, or have other adverse consequences

Our business is subject to a wide range of complex U.S. and foreign laws and regulations, including, but not limited to, the laws and regulations described in the “Industry Regulation” section in Part I, Item 1 of this Annual Report on Form 10-K. Failure to comply with laws and regulations applicable to our operations or client solutions and services could cause us to incur substantial costs or could result in the suspension or revocation of licenses or registrations, the limitation, suspension or termination of services, the imposition of consent orders or civil and criminal penalties, including fines, and lawsuits, including class actions, that could damage our reputation and have a materially adverse effect on our results of operation or financial condition.

In addition, changes in laws or regulations, or changes in the interpretation of laws or regulations by a regulatory authority, may decrease our revenues and earnings and may require us to change the manner in which we conduct some aspects of our business. For example, a change in regulations either decreasing the amount of taxes to be

withheld or allowing less time to remit taxes to government authorities would adversely impact average client balances and, thereby, adversely impact interest income from investing client funds before such funds are remitted to the applicable taxing authorities. Changes in U.S. or foreign tax laws, regulations or rulings or the interpretation thereof could adversely affect our effective tax rate and our net income. Changes in laws, or interpretations thereof, that govern the co-employment arrangement between a professional employer organization and its worksite employees may require us to change the manner in which we conduct some aspects of our PEO business. In addition, changes in the manner in which health and welfare plans sponsored by PEOs or the TotalSource Health and Welfare Plan, in particular, are regulated could adversely impact the demand for our PEO offering.

Because our PEO is a co-employer with our PEO clients and a Certified PEO by the Internal Revenue Service, we may be subject to certain obligations, responsibilities and liabilities of an employer with respect to Worksite Employees (WSE), including with respect to their wages and the payment thereof, the payment of certain taxes with respect to WSE wages and employee benefits provided to the WSEs. Even though PEO clients are contractually responsible for the timely remittance of such costs, it is possible that our clients will not remit such payments despite their contractual obligations. The risk of failing to receive such payments from PEO clients could be magnified during significant financial or other disruptions or catastrophic events, such as the failure of a bank, like that of Signature Bank or Silicon Valley Bank, with whom a significant number of PEO clients may bank at the time, or more widespread stress or failure within the U.S. banking system. Any such event could prevent or materially delay the recovery of any payments not timely remitted and could have an adverse impact on our financial results and liquidity.

Our Wisely offerings and potentially other future offerings in the payments and/or consumer space may subject us to additional laws and regulations, some of which may not be uniform and may require us to modify or restrict our offerings and decrease our potential revenue and earnings.

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

Regulators worldwide continue to exercise a high level of scrutiny with respect to anti-corruption, economic and trade sanctions, and anti-money laundering laws and regulations. Such scrutiny has resulted in aggressive investigations and enforcement of such laws and burdensome regulations, any of which could materially adversely impact our business. We operate our business around the world, including in numerous developing economies where companies and government officials are more likely to engage in business practices that are

prohibited by domestic and foreign laws and regulations, including the United States Foreign Corrupt Practices Act and the U.K. Bribery Act 2010. Such laws generally prohibit improper payments or offers of payments to foreign government officials and leaders of political parties and, in some cases, to other persons, for the purpose of obtaining or retaining business. We are also subject to economic and trade sanctions programs, including those administered by the U.S. Treasury Department’s Office of Foreign Assets Control, which prohibit or restrict transactions or dealings with specified countries, their governments and, in certain circumstances, their nationals, and with individuals and entities that are specially designated, including narcotics traffickers and terrorists or terrorist organizations, among others. In addition, some of our businesses and entities in the U.S. and a number of other countries in which we operate are subject to anti-money laundering laws and regulations, including, for example, The Bank Secrecy Act of 1970, as amended by the USA PATRIOT Act of 2001 (the “BSA”). Among other things, the BSA requires certain financial institutions, including banks and money services businesses (such as national trust banks and providers of prepaid access like us), to develop and implement risk-based anti-money laundering programs, report large cash transactions and suspicious activity, and maintain transaction records. We have registered our payroll card business as a provider of prepaid access, and registered our ADP Trust Bank with the Treasury Department’s Financial Crimes Enforcement Network (FinCEN).

We have implemented policies and procedures to monitor and address compliance with applicable anti-corruption, economic and trade sanctions and anti-money laundering laws and regulations, and we regularly review, upgrade and enhance our policies and procedures. However, there can be no assurance that our employees, consultants or agents will not take actions in violation of our policies for which we may be ultimately responsible, or that our policies and procedures will be adequate or will be determined to be adequate by regulators. Any violations of applicable anti-corruption, economic and trade sanctions or anti-money laundering laws or regulations could limit certain of our business activities until they are satisfactorily remediated and could result in civil and criminal penalties, including fines, which could damage our reputation and have a materially adverse effect on our results of operation or financial condition. Further, bank regulators continue to impose additional and stricter requirements on banks to ensure they are meeting their BSA obligations, and banks are increasingly viewing money services businesses and third-party senders to be higher risk customers for money laundering. As a result, our banking partners that assist in processing our money movement transactions may limit the scope of services they provide to us or may impose additional material requirements on us. These regulatory restrictions on banks and changes to banks’ internal risk-based policies and procedures may result in a decrease in

the number of banks that may do business with us, may require us to materially change the manner in which we conduct some aspects of our business, may decrease our revenues and earnings and could have a materially adverse effect on our results of operations or financial condition.

Failure to comply with privacy, data protection, artificial intelligence and cyber security laws and regulations could have a materially adverse effect on our reputation, results of operations or financial condition, or have other adverse consequences

The collection, storage, hosting, transfer, processing, disclosure, use, security and retention and destruction of personal information required to provide our services is subject to federal, state and foreign privacy, data protection and cyber security laws. These laws, which are not uniform, generally do one or more of the following: regulate the collection, storage, hosting, transfer (including in some cases, the transfer outside the country of collection), processing, disclosure, use, security and retention and destruction of personal information; require notice to individuals of privacy practices; give individuals certain access and correction rights with respect to their personal information; and regulate the use or disclosure of personal information for secondary purposes such as marketing. Under certain circumstances, some of these laws require us to provide notification to affected individuals, clients, data protection authorities and/or other regulators in the event of a data breach. In many cases, these laws apply not only to third-party transactions, but also to transfers of information among the Company and its subsidiaries. The European Union (the “EU”) General Data Protection Regulation (the “GDPR”), and state consumer privacy laws like the California Privacy Rights Act of 2020 (the “CPRA”), are among the most comprehensive of these laws, and more and more jurisdictions are adopting similarly comprehensive laws that impose new data privacy protection requirements and restrictions. As part of our overall data protection compliance program in connection with the GDPR, we implemented Binding Corporate Rules (“BCRs”) as both a data processor and data controller, which permits us to process and transfer personal data across borders in compliance with EU data protection laws.

We believe that providing insights and content from data, including via artificial intelligence (AI) and machine learning (ML), will become increasingly important to the value that our solutions and services deliver to our clients. We are increasingly leveraging AI and ML in our solutions and service delivery and are exploring how best to integrate generative AI technologies and develop and deploy capabilities that are beneficial to our clients and their employees. However, legislation that would govern the development and/or use of AI is under consideration in the U.S. at the state and local 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 these 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, regulatory or self-regulatory requirements or ethical considerations, including our own published, 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.

Complying with privacy, data protection, AI and cyber security laws and requirements, including the enhanced obligations imposed by the GDPR, our BCRs and the CPRA, may result in significant costs to our business and require us to amend certain of our business practices. Further, enforcement actions and investigations by regulatory authorities related to data security incidents and privacy violations continue to increase. The 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 businesses and noncompliance could result in significant regulatory penalties and legal liability and damage our reputation. In addition, data security events, concerns about privacy abuses by other companies and increased awareness of the potential (positive and negative) of AI are changing consumer and social expectations for enhanced protections (including with respect to bias and potential discrimination). As a result, noncompliance, the failure to meet such expectations or the perception of noncompliance or such failure, whether or not valid, may damage our reputation.

If we fail to protect our intellectual property rights, it could materially adversely affect our business and our brand

Our ability to compete and our success depend, in part, upon our intellectual property. We rely on patent, copyright, trade secret and trademark laws, and confidentiality or license agreements with our employees, clients, vendors, partners and others to protect our intellectual property rights. We may need to devote significant resources, including cybersecurity resources, to monitoring our intellectual property rights. In addition, the steps we take to protect our intellectual property rights may be inadequate or ineffective, or may not provide us with a significant competitive advantage. Our intellectual property could be wrongfully acquired as a result of a cyber-attack or other wrongful conduct by third parties or our personnel. Litigation brought to protect and enforce our intellectual property rights could be costly and time-consuming. Furthermore, our efforts to enforce our intellectual property rights may be met with defenses, counterclaims, and countersuits attacking the validity and enforceability of our intellectual property rights, which

may be successful. In addition, use of AI tools may result in the release of confidential or proprietary information which could limit our ability to protect, or prevent us from protecting, our intellectual property rights.

We may be sued by third parties for infringement of their proprietary rights, which could have a materially adverse effect on our business, financial condition or results of operations

There is considerable intellectual property development activity in our industry. Third parties, including our competitors, may own or claim to own intellectual property relating to our products or services and may claim that we are infringing their intellectual property rights. Additionally, as we expand our use of AI, there is uncertainty regarding intellectual property ownership and license rights of AI algorithms and content generated by AI and we may become subject to similar claims of infringement. We may be found to be infringing upon third party intellectual property rights, even if we are unaware of their intellectual property rights. Any claims or litigation could cause us to incur significant expenses and, if successfully asserted against us or if we decide to settle, could require that we pay substantial damages or ongoing royalty payments, obtain licenses, modify applications, prevent us from offering our services, or require that we comply with other unfavorable terms. We may also be obligated to indemnify our clients, vendors or partners in connection with any such claim or litigation. Even if we were to prevail in such a dispute, any litigation could be costly and time-consuming.

SECURITY AND TECHNOLOGY RISKS

Our businesses collect, host, store, transfer, process, disclose, use, secure and retain and dispose of personal and business information, and collect, hold and transmit client funds, and a security or privacy breach may damage or disrupt our businesses, result in the disclosure of confidential information, damage our reputation, increase our costs, cause losses and materially adversely affect our results of operations

In connection with our business, we collect, host, store, transfer, process, disclose, use, secure and retain and dispose of large amounts of personal and business information about our clients, employees of our clients, our vendors and our employees, contractors and temporary staff, including payroll information, health care information, personal and business financial data, social security numbers and their foreign equivalents, bank account numbers, tax information and other sensitive personal and business information. We also collect significant amounts of funds from the accounts of our clients and transmit them to their employees, taxing authorities and other third parties.

We are focused on ensuring that we safeguard and protect personal and business information and client funds, and we devote significant resources to maintain and regularly update our systems and processes. Nonetheless, the global environment continues to grow increasingly hostile as attacks on information technology systems continue to grow in frequency, complexity and sophistication, and we are regularly targeted by unauthorized parties using malicious tactics, code and viruses. Certain of these malicious parties may be state-sponsored and/or supported by significant financial and technological resources. Although this is a global problem, it may affect our businesses more than other businesses because malevolent parties (including our personnel) may focus on the amount and type of personal and business information that our businesses collect, host, store, transfer, process, disclose, use, secure and retain and dispose of, and the client funds that we collect and transmit.

We have programs and processes in place to prevent, detect and respond to data or cybersecurity incidents. However, as a result of the complexity of our operating environment, the period over which hardware and software has been acquired or other reasons, our programs and processes may not be sufficient or adequate or may fail to prevent, detect or respond to a cybersecurity incident or identify and/or remediate a security vulnerability in our operating environment. The techniques used to obtain unauthorized access, disable or degrade service, or sabotage systems change frequently, are increasingly more complex and sophisticated (including due to the use of AI). We may fail to anticipate or detect these techniques and/or incidents for long periods of time and, even when we do so, we may be unable or fail to implement adequate or timely preventive or responsive measures. Our ability to address data or cybersecurity incidents may also depend on the timing and nature of assistance that may be provided from relevant governmental or law enforcement agencies. Hardware, software, applications or services that we develop or procure from third parties, or are required by third parties such as foreign governments to install on our systems, may contain defects in design or manufacture or other problems that could (or, in respect of third-party software, may be designed to) compromise the confidentiality, integrity or availability of data or our systems. Unauthorized parties also attempt to gain access to our systems or facilities, or those of third parties with whom we do business, through fraud, trickery, or other methods of deceiving these third parties or our personnel, including phishing and other social engineering techniques whereby attackers use end-user behaviors to distribute computer viruses and malware into our systems or otherwise compromise the confidentiality, integrity or availability of data or our systems. As these threats continue to evolve and increase (including due to the use of AI), we continue to invest significant resources, and may be required to invest significant additional resources, to modify and enhance our information security and controls

and to investigate and remediate any security vulnerabilities. In addition, while our operating environments are designed to safeguard and protect confidential personal and business information, we may not have the ability to monitor the implementation or effectiveness of any safeguards by our clients, vendors or partners and, in any event, third parties may be able to circumvent those security measures. Information obtained by malevolent parties (including our personnel) resulting from successful attacks against our clients, vendors, partners or other third parties may, in turn, be used to attack our information technology systems.

A cyberattack, unauthorized intrusion, malicious software infiltration, network disruption, denial of service, corruption of data, ransomware attack, theft of non-public or other sensitive information, or similar act by a malevolent party (including our personnel), or inadvertent acts or inactions by our vendors, partners or personnel, could result in the loss, disclosure or misuse of confidential personal or business information or the theft of client or ADP funds, which could have a materially adverse effect on our business or results of operations or that of our clients, result in liability, litigation, regulatory investigations and sanctions or a loss of confidence in our ability to serve clients, or cause current or potential clients to choose another service provider. As the global environment continues to grow increasingly hostile, the security of our operating environment is ever more important to our clients and potential clients. As a result, the breach or perceived breach of our security systems could result in a loss of confidence by our clients or potential clients and cause them to choose another service provider, which could have a materially adverse effect on our business.

Although we believe that we maintain a robust program of information security and controls and none of the data or cybersecurity incidents that we have encountered to date have materially impacted us, a data or cyber security incident could have a materially adverse effect on our business, results of operations, financial condition and reputation. While ADP maintains insurance coverage that, subject to policy terms and conditions and a significant self-insured retention, is designed to address losses or claims that may arise in connection with certain aspects of data and cyber risks, such insurance coverage may be insufficient to cover all losses or all types of claims that may arise in the continually evolving area of data and cyber risk.

Our systems, applications, solutions and services may be subject to disruptions that could have a materially adverse effect on our business and reputation

Many of our businesses are highly dependent on our ability to process, on a daily basis, a large number of complicated transactions. We rely heavily on our payroll, financial,

accounting, and other data processing systems. We need to properly manage our systems, applications and solutions, and any upgrades, enhancements and expansions we may undertake from time to time, in order to ensure they properly support our businesses. From time to time, these systems, applications or solutions fail to operate properly or become disabled. Any such failure or disablement, even for a brief period of time, whether due to malevolent acts, errors, defects or any other factor(s), could result in financial loss, a disruption of our businesses, liability to clients, loss of clients, regulatory intervention or damage to our reputation, any of which could have a materially adverse effect on our results of operation or financial condition. We have disaster recovery, business continuity, and crisis management plans and procedures designed to protect our businesses against a multitude of events, including natural disasters, military or terrorist actions, power or communication failures, or similar events. Despite our preparations, our plans and procedures may not be successful in preventing or mitigating the loss of client data or funds, service interruptions, disruptions to our operations, or damage to our important facilities. In addition, the severity of the failure or disablement may require us to replace or rebuild the affected system(s), application(s) or solution(s) and we may be unable to do so before it materially adversely affects our business.

A disruption of the data centers or cloud-computing or other technology services or systems that we utilize could have a materially adverse effect on our business

We host our applications and serve our clients with data centers that we operate, and with data centers that are operated, and cloud-computing and other technology services and systems that are provided, by third-party vendors. These data centers or cloud-computing and other technology services and systems have (and, in the future, may) failed, become disabled or been disrupted. Any failure, disablement or disruption, even for a limited period of time, could disrupt our businesses and we could suffer financial loss, liability to clients, loss of clients, regulatory intervention or damage to our reputation, any of which could have a material adverse effect on our results of operation or financial condition. In addition, our third-party vendors may cease providing data center facilities or cloud-computing or other technology services or systems, elect to not renew their agreements with us on commercially reasonable terms or at all, breach their agreements with us or fail to satisfy our expectations, which could disrupt our operations and require us to incur costs which could materially adversely affect our results of operation or financial condition.

BUSINESS AND INDUSTRY RISKS

Our industry is subject to rapid technological change, including as a result of AI, and if we fail to upgrade, enhance and expand our technology and services to meet client needs and preferences, the demand for our solutions and services may materially diminish

Our businesses operate in industries that are subject to rapid technological advances (such as AI) and changing client needs and preferences. In order to remain competitive and responsive to client demands, we continually upgrade, enhance, and expand our technology, solutions and services, including by leveraging AI in our solutions. If we fail to respond successfully to technology challenges and client needs and preferences or our competitors or other third parties respond to such challenges more quickly or successfully than us, the demand for our solutions and services may diminish. As new technologies (such as AI) continue to emerge, they may be disruptive to the HCM industry. These technologies could result in new and innovative HCM products and solutions that could increase competition, place us at a competitive disadvantage or even render obsolete our technology, products and solutions. In addition, investment in product development and new technologies often involves a long return on investment cycle. We have made and expect to continue to make significant investments in product development and new technologies. We must continue to dedicate a significant amount of resources to our development efforts before knowing to what extent our investments will result in products the market will accept. In addition, our business could be adversely affected in periods surrounding our new product introductions if clients delay purchasing decisions to evaluate the new product offerings. Furthermore, we may not execute successfully on our product development strategy, including because of challenges with regard to product planning and timing and technical hurdles that we fail to overcome in a timely fashion. We may fail to realize all the economic benefit of our investment in the development of a product which could cause an impairment of goodwill or intangibles and result in a significant charge to earnings.

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, operations, financial condition, results of operations and competitive position

We have been and will be undertaking certain transformation initiatives, which are designed to streamline our organization, extend our world-class distribution 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 or ineffective, we may fail to meet our financial goals and achieve anticipated benefits, improvements may be delayed, not sustained or not realized and our business, operations and competitive position could be adversely affected. 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.

A major natural disaster or catastrophic event could have a materially adverse effect on our business, operations, financial condition and results of operations, or have other adverse consequences

Our business, operations, financial condition, results of operations, access to capital markets and borrowing costs may be adversely affected by a major natural disaster or catastrophic event, including civil unrest, geopolitical instability, war, terrorist attack, pandemics or other (actual or threatened) public health emergencies, extreme weather, such as droughts, hurricanes, flooding and wildfires (including as a result of climate change), or other events beyond our control, and measures taken in response thereto.

The COVID-19 outbreak created, and such other events may create, significant volatility and uncertainty and economic and financial market disruption. The extent of any such impact depends on developments which are highly uncertain and cannot be predicted, including the duration and scope of the event; the governmental and business actions taken in response thereto; actions taken by the Company in response thereto and the related costs; the impact on economic activity and employment levels; the effect on our clients, prospects, suppliers and partners; our ability to sell and provide our solutions and services, including due to travel restrictions, business and facility closures, and employee remote working arrangements; the ability of our clients or prospects to pay for our services and solutions; and how quickly and to what extent normal economic and operating conditions can resume. In addition, clients or prospects may delay decision making, demand pricing and other concessions, reduce the value or duration of their orders, delay planned work or seek to terminate existing agreements. Our business is also impacted by employment levels across our clients, as we have varied contracts throughout our business that blend base fees and per-employee fees.

Political, economic and social factors may materially adversely affect our business and financial results

Trade, monetary and fiscal policies, and political and economic conditions may substantially change, and credit markets may experience periods of constriction and volatility. A slowdown in the economy or other negative changes, including in employment levels, the level of interest rates or the level of inflation, may have a negative impact on our businesses. In addition, as our operating costs increase due to inflationary pressure or otherwise, we may not be able to offset these increases by corresponding price increases for our products and solutions. Clients may react to worsening conditions by reducing their spending on HCM services or renegotiating their contracts with us, which may adversely affect our business and financial results.

We invest our funds held for clients in liquid, investment-grade marketable securities, money market securities, 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.

In addition, as part of our client funds investment strategy, we extend the maturities of our investment portfolio for client funds and utilize short-term financing arrangements to satisfy our short-term funding requirements related to client funds obligations. In order to satisfy these short-term funding requirements, we maintain access to various sources of liquidity, including borrowings under our commercial paper program and our committed credit facilities, our ability to execute reverse repurchase transactions and corporate cash balances. A reduction in the availability of any such financing during periods of disruption in the financial markets or otherwise may increase our borrowing costs and/or require us to sell available-for-sale securities in our funds held for clients to satisfy our short-term funding requirements. When there is a reduction in employment levels due to a slowdown in the economy, the Company may experience a decline in client fund obligations and may also sell available-for-sale securities in our funds held for clients in order to reduce the size of the funds held for clients to correspond to client fund obligations. A sale of such available-for-sale securities may result in the recognition of losses and reduce the interest income earned on funds held for clients, either or both of which may adversely impact our results of operations, financial condition and cash flow.

In connection with our client funds assets investment strategy, we attempt to minimize the risk of not having funds collected from a client available at the time such client’s obligation becomes due by generally impounding the client’s funds at the time of payment of such client’s obligation. When we don’t impound client funds by the time we pay such client obligations (including for PEO clients with respect to which we are legally obligated for payroll and tax obligations in respect of WSEs as a Certified PEO), we are at risk of not recovering such funds or a material delay in such recovery. Such risk could be magnified during significant financial or other disruptions or catastrophic events, such as the failure of a bank with whom a significant number of clients may bank at the time or more widespread stress or failure within the U.S. banking system. Any such event could prevent or materially delay the recovery of any funds from clients and could have an adverse impact on our financial results and liquidity.

We are dependent upon various large banks to execute electronic payments and wire transfers as part of our client payroll, tax and other money movement services. While we have contingency plans in place for bank failures, a

systemic shutdown of the banking industry would impede our ability to process funds on behalf of our payroll, tax and other money movement services clients and could have an adverse impact on our financial results and liquidity.

We derive a significant portion of our revenues and operating income outside of the United States and, as a result, we are exposed to market risk from changes in foreign currency exchange rates that could impact our results of operations, financial position and cash flows.

We publicly share certain information about our environmental, social and governance (“ESG”) initiatives, including our net zero greenhouse gas emissions pledge. We may face increased scrutiny related to our ESG initiatives and any related targets, including from the investment community. In addition, our ability to achieve certain ESG initiatives and targets may depend on the actions or continuing requirements of governmental entities (e.g., our paperless initiatives may depend on whether certain states continue to require employers to offer employees to be paid via paper check or to obtain employee consent to be paid electronically instead of via paper check). Our failure to achieve progress in these and other ESG areas on a timely basis, or at all, could impact our reputation, business, including employee retention, and growth.

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

The major credit rating agencies periodically evaluate our creditworthiness and have given us strong, investment-grade long-term debt ratings and high commercial paper ratings. Failure to maintain high credit ratings on long-term and short-term debt could increase our cost of borrowing, reduce our ability to obtain intra-day borrowing required by our Employer Services business, and adversely impact our results of operations.

Our business could be negatively impacted as a result of actions by activist stockholders or others

We may be subject to actions or proposals from activist stockholders or others that may not align with our business strategies or the interests of our other stockholders. Responding to such actions could be costly and time-consuming, disrupt our business and operations, and divert the attention of our Board of Directors and senior management from the pursuit of our business strategies. Activist stockholders may create perceived uncertainties as to the future direction of our business or strategy, including with respect to our ESG efforts, which may be exploited by our competitors and may make it more difficult to attract and retain qualified personnel, potential clients and business partners and may affect our relationships with current clients, vendors, investors and other third parties. In addition, actions of activist stockholders may cause periods of fluctuation in our stock price based on temporary or

speculative market perceptions or other factors that do not necessarily reflect the underlying fundamentals and prospects of our business.

We may be unable to attract and retain qualified personnel

Our ability to grow and provide our clients with competitive services is, to an important degree, dependent on our ability to attract and retain highly skilled and motivated people reflecting diverse perspectives and the diversity of our communities and clients. Competition for skilled employees in the outsourcing and other markets in which we operate is increasingly intense, making it more difficult and expensive to attract and retain highly skilled, motivated and diverse personnel. If we are unable to attract and retain highly skilled, motivated and diverse personnel, results of our operations and culture may suffer.

In addition, the nature of the office environment and remote or hybrid working is changing, which may make it more difficult to attract and retain personnel. It may also present operational and workplace culture challenges that may adversely affect our business.

Risk Factors,” and in other written or oral statements made from time to time by ADP, should be considered in evaluating any forward-looking statements contained herein.

NON-GAAP FINANCIAL MEASURES

In addition to our U.S. GAAP results, we use adjusted results and other non-GAAP metrics to evaluate our operating performance in the absence of certain items and for planning and forecasting of future periods. Adjusted EBIT, adjusted EBIT margin, adjusted net earnings, adjusted diluted earnings per share, adjusted effective tax rate and organic constant currency are all non-GAAP financial measures. Please refer to the accompanying financial tables in the “Non-GAAP Financial Measures” section for a discussion of why ADP believes these measures are important and for a reconciliation of non-GAAP financial measures to their comparable GAAP financial measures.

EXECUTIVE OVERVIEW

Highlights from the year ended June 30, 2023 include:

We are a leading global provider of cloud-based Human Capital Management (“HCM”) technology solutions to employers around the world. Our HCM solutions, which include both software and outsourcing services, are designed to help our clients manage their workforce through a dynamic business and regulatory landscape and the changing world of work. We continuously seek to enhance our leading HCM solutions to further support our clients. We see tremendous growth opportunity ahead as we focus on our three key Strategic Priorities: leading with best-in-class HCM technology, providing unparalleled expertise and outsourcing, and leveraging our global scale for the benefit of our clients. Executing on our Strategic Priorities will be critical to enabling our growth in the years ahead.

During the fiscal year we drove strong progress across a number of key measures and in support of our overall Strategic Priorities. We crossed a major milestone, surpassing the 1 million client mark, driven by continued enhancements to our key solutions like RUN and Workforce Now. We continued the deployment of our unified User Experience to key portions of our portfolio such as the RUN mobile app. We were awarded Top HR Product for the 8th consecutive year at the annual HR Tech Conference, in recognition for our recently launched Intelligent Self Service Solution. And our HR Outsourcing businesses continued to grow, now with over 3 million worksite employees served.

For fiscal 2023, we delivered solid revenue growth of 9%, 10% organic constant currency. Our pays per control metric, which represents the number of employees on ADP clients' payrolls in the United States when measured on a same-store-sales basis for a subset of clients ranging from small to large businesses, grew 4.7% for the year ended June 30, 2023 as compared to the year ended June 30, 2022. PEO average worksite employees increased 6% for the year ended June 30, 2023, as compared to the year ended June 30, 2022. Additionally, our strong ES new business bookings performance resulted in full year fiscal 2023 growth of 10%, and client satisfaction gains resulted in a full year ES client revenue retention rate of 92.2%, equal to the highest level we have ever reported. We believe these results are largely attributable to improvements made to our platforms and service over multiple years.

We have a strong business model, generating significant cash flows with low capital intensity, and offer a suite of products that provide critical support to our clients’ HCM functions. We generate sufficient free cash flow to satisfy our cash dividend and our modest debt obligations, which enables us to absorb the impact of downturns and remain steadfast in our re-investments, longer term strategy, and commitments to shareholder friendly actions. We are committed to building upon our past successes by investing in our business through enhancements in research and development and by driving meaningful transformation in the way we operate. Our financial condition remains solid at June 30, 2023 and we remain well positioned to support our associates and our clients.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of

Automatic Data Processing, Inc.

Roseland, New Jersey

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Automatic Data Processing, Inc. and subsidiaries (the "Company") as of June 30, 2023 and 2022, and the related statements of consolidated earnings, comprehensive income, stockholders' equity, and cash flows for each of the three years in the period ended June 30, 2023, and the related notes and the schedule listed in the Index at Item 15(a)2 (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 June 30, 2023 and 2022, and the results of its operations and its cash flows for each of the three years in the period ended June 30, 2023, 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 June 30, 2023, 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 August 3, 2023, 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 Matters

The critical audit matters communicated below are matters arising from the current-period audit of the financial statements that were communicated or required to be communicated to the audit committee and that (1) relate 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 matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Goodwill – Employer Services Reportable Segment— Refer to Notes 1 and 7 to the financial statements

Critical Audit Matter Description

The Company’s evaluation of goodwill for impairment involves the comparison of the fair value of each reporting unit to its carrying value. The Company uses the discounted cash flow model to estimate fair value which requires management to make significant estimates and assumptions related to forecasts of future revenue and operating margin. In addition, the discounted cash flow model requires the Company to select an appropriate weighted average cost of capital based on current market conditions as of June 30, 2023. Changes in these assumptions could have a significant impact on either the fair value, the amount of any goodwill impairment charge, or both.

Forecasts of future revenue and operating margin from the Company’s next-gen platform, for which there is limited historical data, contribute significantly to the estimate of fair value of a reporting unit within the Employer Services reportable segment with approximately $678 million of goodwill as of June 30, 2023. Given the limited historical data associated with the Company’s next-gen platform, significant management judgment was required to forecast future revenue and operating margin to estimate the fair value of the reporting unit. In turn, a high degree of auditor judgment and an increased extent of audit effort were required when performing

audit procedures to evaluate the reasonableness of management’s estimates and assumptions related to the forecasts of revenue and operating margin and the selection of the weighted average cost of capital, including the involvement of our fair value specialists.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the forecasts of future revenue and operating margin and the selection of the weighted average cost of capital used by management to estimate the fair value contributed by the next-gen platform included the following, among others:

• We tested the effectiveness of controls over management’s goodwill impairment evaluation, including those over the determination of the fair value of the reporting unit within the Employer Services reportable segment, such as controls related to management’s forecasts of future revenue and operating margin and the selection of the weighted average cost of capital.

• With the assistance of our fair value specialists, we evaluated the reasonableness of the valuation models, methodology, and significant assumptions used by the Company, specifically the weighted average cost of capital including:

◦Testing the mathematical accuracy of the Company’s calculation of the weighted average cost of capital.

◦Developing a range of independent estimates and compared to the weighted average cost of capital selected by management.

• We evaluated management’s ability to accurately forecast future revenue and operating margin by comparing actual results to management’s historical forecasts. Due to the limited historical data for the next-gen platform, we evaluated the reasonableness of management’s revenue and operating margin forecasts by comparing the forecasts to (1) the historical operating results of the Company’s similar existing platforms, (2) the limited operating results to date of the next-gen platform, (3) internal communications to management and the board of directors, and (4) external communications made by management to analysts and investors.

Client Funds Obligations - Refer to Note 4 to the financial statements

Critical Audit Matter Description

Client funds obligations represent the Company's contractual obligations to remit funds to satisfy clients' payroll, tax and other payee payment obligations and are recorded as a liability at the time that the Company impounds funds from clients (i.e., money movement). The Company has reported client funds obligations as a current liability in the consolidated financial statements totaling $38,538.6 million as of June 30, 2023. This money movement activity involves significant amounts of client funds being impounded and remitted to third parties and results in a high volume of transactions.

To validate the accuracy and completeness of the client funds obligations reported as of period end, the Company performs complex data extracts in order to reconcile the transactional

Attached as Exhibits 31.1 and 31.2 to this Annual Report on Form 10-K are certifications of ADP's Chief Executive Officer and Chief Financial Officer, which are required by Rule 13a-14(a) of the Securities Exchange Act of 1934, as amended (the

“Exchange Act”). This “Controls and Procedures” section should be read in conjunction with the report of Deloitte & Touche LLP that appears in this Annual Report on Form 10-K and is hereby incorporated herein by reference.

Management's Evaluation of Disclosure Controls and Procedures

The Company carried out an evaluation (the “evaluation”), under the supervision and with the participation of the Company's management, including its Chief Executive Officer and Chief Financial Officer, of the effectiveness of the Company's disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the Company's management, including its Chief Executive Officer and Chief Financial Officer, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. Based on the evaluation, the Company's Chief Executive Officer and Chief Financial Officer have concluded that the Company's disclosure controls and procedures were effective as of June 30, 2023 in ensuring that (i) information required to be disclosed by the Company in reports that it files or submits under the Exchange Act is accumulated and communicated to the Company's management, including its Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosure and (ii) such information is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms.

Management's Report on Internal Control over Financial Reporting

It is the responsibility of Automatic Data Processing, Inc.'s (“ADP”) management to establish and maintain effective internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act). Internal control over financial reporting is designed to provide reasonable assurance to ADP's management and board of directors regarding the preparation of reliable financial statements for external purposes in accordance with generally accepted accounting principles.

ADP's internal control over financial reporting includes those policies and procedures that: (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of ADP; (ii) 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 ADP are being made only in accordance with authorizations of management and directors of ADP; and (iii) provide reasonable assurance regarding the prevention or timely detection of unauthorized acquisition, use or disposition of ADP's assets that could have a material effect on the financial statements of ADP.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

Management has performed an assessment of the effectiveness of ADP’s internal control over financial reporting as of June 30, 2023 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, management determined that ADP’s internal control over financial reporting was effective as of June 30, 2023.

Deloitte & Touche LLP, the independent registered public accounting firm that audited and reported on the consolidated financial statements of ADP included in this Annual Report on Form 10-K, has issued an attestation report on the operating effectiveness of ADP's internal control over financial reporting. The Deloitte & Touche LLP attestation report is set forth below.

Changes in Internal Control over Financial Reporting

There were no changes in ADP's internal control over financial reporting that occurred during the quarter ended June 30, 2023 that have materially affected, or are reasonably likely to materially affect, ADP's internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of

Automatic Data Processing, Inc.

Roseland, New Jersey

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Automatic Data Processing, Inc. and subsidiaries (the “Company”) as of June 30, 2023, 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 June 30, 2023, 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 June 30, 2023, of the Company and our report dated August 3, 2023, 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.
