    BUSINESS OVERVIEW

    ADP’s Mission

    Our mission is to help businesses make meaningful change in the world of work by providing insightful HCM solutions that meet the evolving needs of our clients and their workers.

    As new technologies and shifting workplace dynamics continuously reshape the way people work, we support every HCM need of our clients whether that client is a small, local business or a large, global enterprise operating around the world. From HR, payroll, time and benefits to HR outsourcing, talent, compliance and retirement, our solutions span the entire employee experience from hire to retire. Our leading technology and commitment to service excellence are at the core of our relationship with each one of our clients, which span over 140 countries and territories. We are always designing better ways to work through industry leading products, premium services and exceptional experiences that enable people to reach their full potential all around the world.

    ADP’s Strategy
    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 three strategic priorities:
    • Lead with Best-in-Class HCM Technology. We design and develop world-class HCM platforms that simplify work and utilize enabling technologies such as artificial intelligence (“AI”) and modern cloud architecture. We aim to solve the needs of our clients and their workers today by making HCM transactions compliant and effortless, while anticipating their needs of tomorrow by incorporating valuable data insights and guidance into our solutions to help them better understand their workforce 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 regulations, and to offer thoughtful strategies to utilize HCM technology to achieve their business objectives and support their workforce. Many of our clients also ask us to take on responsibility for a portion or all of their HCM workflows via one of our Human Resources Outsourcing (“HRO”) solutions. We 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 significant data insights and investments in AI and other technologies to further enable and effectively apply our decades of knowledge and experience 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 see meaningful opportunities to leverage our strength in global payroll and expand our HR and workforce management
    4



    solutions to support our global and multinational clients. We continue 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 best address their unique needs. And we intend to grow our sales organization and continue to invest in best-in-class sales technology to not only optimize the purchase experience but to also empower our sellers to provide the deep expertise and insights our clients require to ensure they have the right HCM solutions to help them achieve their objectives and make a meaningful impact for their employees.

    Innovation at ADP
    Innovation is in our DNA. For over 75 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. As a founder in the industry, we pioneered HCM automation, HCM in the cloud, mobile HCM and a digital HCM marketplace, laying the groundwork and streamlining our infrastructure to innovate at a faster pace. This spirit of innovation remains a steady guide as we continue to listen and respond to emerging needs. As technologies like AI, machine learning (“ML”) and generative AI change how work happens, we remain focused on providing our clients and associates with HCM technology that is easy to use, powered with smart insights and personalized to support a human-centric experience.


    To bring these solutions to market, we pursue multiple paths to innovation. From leveraging our unique data to provide differentiated insights to collaborating with, or investing in, organizations with complementary products to purchasing solutions that add to our strong foundation, each of these paths helps ADP sustain a culture focused on continuous innovation.

    Strategically infusing AI
    The AI landscape is evolving quickly. As we move from early automation and predictive analytics to AI-enabled workflows, agentic AI is the future of innovation in the HCM space. Our AI strategy is to deliver AI agents for all
    major HCM roles that our clients have. Our clients have employees performing different roles such as payroll, HR, benefits, compensation, and recruiting. Our goal is to deliver AI agents that continue to automate tedious, time heavy tasks and deliver value to these individuals to do more strategic activities. Similarly, we intend to deliver AI role-based agents to our internal associates such as sales, software engineering, testing, product management, service, and implementation.

    To advance these efforts, we continue to roll out ADP Assist, our award-winning cross-platform solution powered by generative AI that transforms data into credible and actionable insights. ADP Assist offers smart, user-centric solutions through a conversational interface that touches every aspect of HR – payroll, time, talent, benefits, recruitment, analytics, reporting, and compliance.

    ADP Assist validates payroll information, checking for payroll anomalies and using generative AI to identify and help resolve missing tax registrations and answer questions by drawing on ADP’s large, up-to-date dataset of compliance information. ADP Assist also uses generative AI to simplify report creation, helping HR practitioners and leaders access internal, national, and global workforce data to analyze compensation, turnover, candidate profile relevancy, and talent market insights. A 2024 AI Breakthrough Award winner, the solution was also recognized in Business Intelligence Group’s 2025 BIG Innovation Awards and 2025 Artificial Intelligence Excellence Awards for driving innovation and possibilities in AI.

    Along with transforming our solutions, we firmly believe AI and generative AI enhance our operations and enable us to elevate the end-to-end client experience. To lean into our service expertise, we continue to extend generative AI capabilities to a broader portion of our service and implementation associates to deliver an even better client experience. We also continue to explore generative AI capabilities to further empower our sellers to be more productive. In addition, we extended AI tools to all of our product developers for coding, testing, and documentation.

    Data is our differentiator
    To harness the power of AI, data is critical – and it’s the foundation of the advantage we bring to our clients. Data is at the core of our products and solutions, informing and driving our approach to innovation and new technology. The global scale and scope of our client base provide us the industry’s largest and deepest HCM dataset with over 1.1 million clients spanning over 140 countries and territories and 42 million workers globally. Our broad and granular data set positions us well to deliver smarter and more tailored HCM agents that we believe will be truly differentiated in the market. Additionally, combining our vast client and service data with client outcomes gives us a deeper understanding of clients’ needs and goals.

    AI represents the next frontier, and our industry-leading data set married to our best-in-class distribution offers
    5



    ADP a distinct, competitive advantage. AI and ML drive many of the key features of ADP’s data products, including ADP DataCloud, our award-winning people analytics solution. ADP DataCloud analyzes aggregated, anonymized and timely HCM and compensation data from more than one million organizations across the U.S., powering solutions that provide clients with in-depth workforce and business insights that enable critical HR decisions.

    Analytics enhanced by ADP Assist leverages generative AI to deliver answers to analytics questions across key practice areas including benefits, HR, payroll, recruitment and time, helping to remove user friction.

    Scalable, Global HCM Offerings
    We also continue to advance our next-gen platforms, launching ADP Lyric HCM in September 2024. Building on our position as a leader in global pay, we designed Lyric to be as dynamic as the world of work. The unified, global HCM solution is designed for adaptability, providing 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. The solution was named “Data Solution of the Year for Human Resources” in the 2025 Data Breakthrough Awards.

    To expand our global offering and enhance our enterprise solution suite, in October 2024 ADP acquired WorkForce Software, a premier workforce management solutions provider that specializes in supporting large, global enterprises. WorkForce Software’s solutions can adapt to the dynamic needs of today’s employers, creating resiliency, driving performance and making managing a global workforce easy. This acquisition expands our current array of global time and attendance, absence management and scheduling tools and will drive workforce management innovation to help meet the future needs of businesses. In addition, ADP acquired Procesamiento Externo de Información, S.C. (PEI) in February 2025, a provider of local payroll, HCM expertise, and technology solutions for Mexican businesses, strengthening ADP’s capabilities in local and global payroll and HR.

    Sustaining a culture of responsible AI
    In harnessing the power of data through AI and 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, 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 and ML technologies.
    Creating a customized HR ecosystem
    To meet clients’ shifting needs, we also collaborate with partners through solutions like ADP Marketplace, one of the largest e-commerce platforms for HR solutions in the industry. This innovative marketplace empowers our clients to connect and share data seamlessly across their HR systems, offering access to over 800 partner solutions - from recruiting and onboarding to compliance and learning management. With the introduction of AI technology, including our generative AI smart search tool, clients can quickly discover and evaluate partner solutions using natural language, enabling clients to tailor their HCM ecosystem with integrated solutions that best fit their unique needs.

    Additionally, ADP API Central offers secure APIs and tools and resources for custom integrations to simplify and automate business processes. This solution was named

    “New Product of the Year” in Business Intelligence Group’s 2024 BIG Awards for Business.

    Accelerating innovation
    Reflecting our commitment to innovation, ADP’s corporate venture capital arm and innovation lab, ADP Ventures, is focused on enhancing and strengthening ADP’s core business, creating offerings in new adjacent segments and geographies, and developing new assets to monetize markets and segments beyond HCM. As part of its strategy, ADP Ventures invests in and partners with early-stage and scaling tech startups that advance ADP’s innovation strategy.

    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 businesses. For financial data by segment and by geographic area, see Note 15 to the “Consolidated Financial Statements” contained in this Annual Report on Form 10-K.

    EXECUTIVE OVERVIEW

    As a global leader in HR and payroll solutions, ADP continuously aims to solve complex business challenges for our clients and their workers. Our Human Capital Management ("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 see tremendous opportunity ahead as we focus on our three key Strategic Priorities: Leading with Best-in-Class HCM technology, Providing Unmatched Expertise and Outsourcing Solutions, and Leveraging our Global Scale for the Benefit of our Clients.

    During the third quarter, we made meaningful progress on our Strategic Priorities. We continued to leverage our data advantages, domain expertise, and trusted brand to lead the HCM industry through its AI transformation. Our ADP Assist agents are applying advanced intelligence to real workforce challenges across payroll and HR, and since their launch in January, our clients have seen meaningful time savings for each payroll processed. ADP Lyric HCM is also saving time for our clients, with one company replacing a dozen disparate systems to achieve a leaner payroll operations model. Additionally, we expanded our AI ecosystem by launching a dedicated space within ADP Marketplace for our partner companies’ AI agents. On the service front, we scaled our GenAI capabilities across our service operations, transforming how our client-facing teams engage, serve, and support our clients across the full lifecycle. Finally, we remained focused on benefiting our clients through our global scale by delivering compliant HCM solutions, local expertise, and trusted relationships wherever they operate.

    Highlights from the nine months ended March 31, 2026 include:

    Revenue growth of 7% to $16,473.6 million; 6% growth on an organic constant currency basis
    Earnings before income taxes margin expansion of 50 bps, and adjusted EBIT margin expansion of 50 bps
    Diluted and adjusted diluted earnings per share ("EPS") growth of 10% and 9%, to $8.49 and $8.48, respectively
    Cash returned via shareholder friendly actions of $3.4B, including $1.9B of dividends and $1.5B of share repurchases

    For the nine months ended March 31, 2026, we delivered strong revenue growth of 7%, 6% growth on an organic constant currency basis. 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 Employer Services clients ranging from small to large businesses, grew 1% for the nine months ended March 31, 2026 as compared to the nine months ended March 31, 2025. PEO average worksite employees increased 2% for the nine months ended March 31, 2026, as compared to the nine months ended March 31, 2025.

    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 long-term strategy and commitments to shareholder friendly actions. We are committed to building upon our past successes by investing in research and development to enhance our products and services and by driving continuous improvement in the way we operate. Our financial condition remains solid at March 31, 2026 and we remain well positioned to support our associates and our clients.

    Adjusted diluted EPS $3.37 $3.06 10 %$8.48 $7.75 %

    In addition to the increase in net earnings, diluted EPS increased for the three and nine months ended ended March 31, 2026 as a result of the impact of fewer shares outstanding resulting from share repurchases under our authorized share repurchase program, partially offset by the issuances of shares under our employee benefit plans. The Company repurchased 2.6 million and 1.0 million shares in the three months ended March 31, 2026 and 2025, respectively, and repurchased 5.7 million and 3.4 million shares in the nine months ended March 31, 2026 and 2025, respectively.

    Adjusted net earnings and adjusted diluted EPS reflect the changes in the components described above for the three and nine months ended March 31, 2026.
