Automatic Data Processing, Inc. (ADP) Stock Price & How to Invest

Automatic Data Processing (ADP) is a Roseland, New Jersey-based global technology company providing cloud-based human capital management (HCM) and payroll solutions to businesses of every size, from single-employee firms using ADP RUN to large multinationals using ADP Workforce Now and Lyric. The company operates through two primary segments: Employer Services, which covers payroll processing, tax filing, benefits administration, talent management, time and attendance, and compliance; and Professional Employer Organization (PEO) Services, under the ADP TotalSource brand, which co-employs client workers to deliver Fortune 500-level benefits packages to smaller firms. ADP also earns a meaningful stream of interest income by holding and investing the client funds it collects between payroll runs before remitting them to employees and tax authorities. Founded in 1949 by Henry Taub and Frank Lautenberg as a manual payroll processor and taken public in 1961, ADP pioneered computerized payroll in the 1960s and grew through decades of acquisitions and organic expansion into its present position as the market leader in global payroll software with roughly 9.9% market share. The company is led by President and CEO Maria Black, who took the helm in 2023, and employs approximately 67,000 people worldwide. ADP's fiscal year ends June 30, and its shares trade on the Nasdaq under the ticker ADP.

ADP's growth is materially sensitive to employment levels and interest rates: a recession that raises unemployment reduces the headcount on which per-employee fees are charged, crimps new-business bookings, and may accelerate small-business client failures, while falling rates shrink the float income earned on client funds held between payroll cycles. A meaningful portion of fiscal 2025's earnings growth came from elevated interest income, a tailwind that the company itself flagged as likely to moderate. Technologically, more modern unified-database competitors such as Workday, Ceridian Dayforce, UKG, and fast-growing challengers like Rippling and Paycom continue to compete on user experience, integration simplicity, and AI capabilities, and could erode ADP's share in the enterprise and mid-market segments over time. Finally, ADP's reliance on third-party cloud infrastructure introduces operational concentration risk, and any significant service disruption could damage client trust in a business where payroll accuracy is non-negotiable.

A simple financial snapshot. These are approximations and refresh quarterly; for current figures see Automatic Data Processing, Inc.'s investor relations page or your broker.

• Revenue (FY2025, ended June 30, 2025): ~$20.6 billion
• Revenue (TTM, trailing twelve months to Mar 2026): ~$21.6 billion
• Net Income (FY2025): ~$4.1 billion
• Adjusted Diluted EPS (FY2025): ~$10.01
• Adjusted EBIT Margin (FY2025): ~26.0%
• P/E Ratio (TTM, as of June 27, 2026): ~20x
• Market Capitalization: ~$87-89 billion
• Dividend Yield (trailing): ~3.0-3.1%

ADP's trailing P/E of roughly 20x represents a meaningful discount to both its own five-year average of approximately 29-30x and to the broader software sector, reflecting a combination of share-price weakness from its 52-week high near $316 and accelerating earnings growth. The adjusted EBIT margin of 26% in fiscal 2025, expanding 50 basis points year-over-year, demonstrates operating leverage even as the company invests heavily in AI and global platform development. Management has guided for fiscal 2026 revenue growth of 5% to 6% and adjusted diluted EPS growth of 8% to 10%, implying continued margin expansion through productivity gains and the lapping of acquisition-related costs.

If you want ADP exposure as part of a larger bundle rather than directly, these ETFs hold it meaningfully. Weights are approximate and refresh quarterly.

There are three common ways to get ADP exposure. Buy shares (or fractional shares) directly at any major broker. Hold an ETF that includes it (XLI, NOBL), which spreads the position across many companies. Or build it into a focused thematic basket, so ADP sits alongside other stocks that express the same thesis.

Walnut takes the basket route. Describe a thesis where ADP fits (for example “AI infrastructure” or “dividend-growth large-caps”) and the AI proposes 5 to 6 constituents with target weights. You review the plan and fund it through your own broker when you're ready.

ADP is a recurring-revenue compounding machine: its payroll and HCM platform processes wages for a significant fraction of the U.S. workforce, it posted $20.6 billion in fiscal 2025 revenue growing at 7%, and its adjusted diluted EPS has risen every year for over a decade. If you believe the global shift toward outsourced, cloud-based workforce administration continues and that ADP's scale advantages and switching costs protect margins through the economic cycle, the question becomes sizing and overlap with other dividend-growth or quality-factor positions, not timing; the risk is that a labor-market contraction or sustained rate decline erodes client funds float income while newer, nimbler HCM platforms continue to chip away at ADP's share of the enterprise and mid-market segments.

Whether ADP is worth buying today depends more on your time horizon and what you already hold than on any single call. We walk through valuation, what would have to go right, and the risks in is ADP a buy?, and where the stock could go from here in the ADP stock forecast.
