Automatic Data Processing, Inc.
Automatic Data Processing, Inc. provides cloud-based human capital management (HCM) solutions worldwide. It operates in two segments, Employer Services and Professional Employer Organization (PEO). The Employer Services segment offers strategic, cloud-based platforms, and human resources (HR) outsourcing solutions. This segment's offerings include RUN Powered by ADP, a software platform for small business payroll, HR, and compliance; ADP Workforce Now, a HCM solution used across mid-sized and large businesses to manage employees; and ADP Lyric HCM, a solution for HR management, payroll, workforce management, talent, and data analytics. Its PEO Services segment provides HR outsourcing solutions under ADP TotalSource name to businesses through a co-employment model. This segment also provides guidance, user-friendly technology, comprehensive employee benefits, and a risk management, safety, and workers' compensation program. The company was founded in 1949 and is headquartered in Roseland, New Jersey.
What does it do?
ADP is the company that makes sure workers across America — and beyond — get paid correctly and on time. When a small coffee shop or a giant hospital needs to run payroll, manage employee benefits, or stay on top of HR paperwork, they often turn to ADP. Think of ADP as the behind-the-scenes engine that handles the boring but critical stuff that every single business with employees needs. They serve over 1 million businesses globally, from the corner store to Fortune 500 companies.
Payroll and HR software might sound boring, but ADP sits at the center of how work gets done in the modern economy — touching roughly 42 million workers in the US alone. As businesses shift away from managing HR in-house and toward outsourcing it to specialists, ADP is one of the biggest direct beneficiaries. With AI starting to reshape HR workflows, ADP's scale gives it a rare advantage: more data than almost any other company on the planet about how businesses hire, pay, and manage people.
How does it make money?
ADP makes money in two main ways. First, its Employer Services segment sells software subscriptions and HR outsourcing to businesses of all sizes — tools like RUN Powered by ADP for small businesses and ADP Workforce Now for mid-to-large companies. Second, its PEO (Professional Employer Organization) segment essentially co-employs workers on behalf of small businesses, handling their HR, benefits, and compliance for a fee. ADP also earns meaningful interest income by holding client payroll funds in float — sitting on billions of dollars between collecting payroll from employers and paying it out to employees — which becomes more valuable when interest rates are high. Total revenue hit $20.6 billion in the latest fiscal year, up from $19.2 billion the prior year.
Why do investors care?
ADP's growth story is built on stickiness and scale. Once a company integrates ADP into its payroll and HR systems, switching is painful and expensive — meaning clients tend to stay for years, giving ADP highly predictable, recurring revenue. The shift toward cloud-based HR software is still playing out globally, giving ADP room to upsell existing customers to more premium products. The wildcard is AI: ADP is embedding AI tools into its platforms to help HR managers make smarter hiring and compensation decisions, which could justify higher prices and deepen client relationships. For this thesis to work, ADP needs to keep winning new clients, retain existing ones, and successfully use AI to make its software feel indispensable.
