About
Automatic Data Processing, Inc. (ADP) is a Roseland, New Jersey-based payroll processing and human capital management company — publicly traded on the NASDAQ (NASDAQ: ADP) as an S&P 500 Information Technology component — providing payroll processing, tax administration, benefits administration, HR management, time and attendance, talent management, and retirement plan services to 1.1 million clients ranging from small businesses (1-49 employees) to large enterprises (1,000+ employees) through approximately 58,000 employees globally. In fiscal year 2024 (ending June 2024), ADP reported revenues of $19.2 billion (+7% year-over-year) and adjusted EPS of $9.14 (+12%), continuing the company's consistent mid-to-high single digit revenue growth and double-digit EPS growth from operating leverage and capital return. CEO Maria Black (appointed 2023, ADP's first female CEO, previously leading ADP's employer services division) leads ADP's strategy of deepening client platform engagement: ADP's "employer of record" (EOR) and professional employer organization (PEO — ADP TotalSource) services handle all payroll, HR compliance, and benefits administration for small and mid-size businesses — creating outsourcing relationships where ADP becomes the operational HR department for companies that lack internal HR expertise. ADP's client fund float (ADP holds $55+ billion in client payroll funds between the time employers fund payroll and ADP distributes payments to employees and tax authorities — a multi-day float period generating interest income on $55B at current interest rates) generated $1.6B+ in interest income in FY2024 as rates remained elevated, creating an earnings tailwind that amplifies ADP revenue growth during high-interest rate environments.
