This Issue — PAYX
Paychex, a current Nasdaq-100® constituent at ~0.19% index weight, does the pay-cycle work most small employers would rather hand off: the payroll run, the tax filings that follow it, time and attendance, benefits enrollment and retirement plans. Fees are charged per pay period, so revenue arrives on the same rhythm a client's own payroll does. In FY2025 the company acquired Paycor, which took it into the mid-market and enterprise HR software segment and added scheduling, workforce management and talent tools (per company disclosures).
Business Model & Revenue Drivers
What Paychex Bills For
Roughly 800,000 businesses pay Paychex to run their pay cycle: the payroll run itself, the tax filings that follow it, time and attendance, benefits enrollment and retirement plans. The company is headquartered in Rochester, New York, employs 17,600 people and closes its fiscal year on May 31.
The economics sit in the repeat. Management Solutions billed $4.868B of $6.301B in FY2026 revenue, with PEO & Insurance Services, which administers co-employment, workers' compensation and health insurance, taking the rest (per company filings). Fees recur every pay period rather than being re-sold each year, which is why gross margin reached 72.4% in FY2025. Paychex also holds client payroll money briefly before wages and taxes go out, and earns interest on it.
Revenue share, FY2026 (per company filings): Management Solutions $4.868B of $6.301B • PEO & Insurance Services, the remainder.
Competitive Moat
Why Clients Stay on the Platform
Payroll is wired into a client's tax filings, benefits and employee records, so changing provider means moving all of it at once. Paychex sells payroll, HR, retirement and insurance as one package, and Bloomberg research attributes its differentiated position to that breadth plus a distribution network of about 800,000 clients. ADP is the primary competitor, with Paycom, Paylocity and Gusto also in the category (per Bloomberg research).
The mix reinforces itself: more services per client raises both the revenue per pay period and the cost of leaving. Gross margin widened every year from FY2021 to FY2025 while revenue compounded at about 8.2% a year over the same period (per company filings). Client counts have grown more slowly since FY2021, between 0.7% and 3.4% a year, so revenue per client does much of the work (per Bloomberg research).
Gross margin (per company filings): FY2021 → FY2025, widening in every year to 72.4%.
Operating Strengths
Three Structural Advantages
- 51 yrs — dividend growth record. A 51-year record of dividend growth (per company filings). The current annualized rate is $4.76 a share.
- $1.7B free cash flow (FY2025). Cash left after capital spending in the year to May 2025, of which 75% to 95% goes back to shareholders, mostly as dividends (per company disclosures).
- 39.6% operating margin (FY2025). Close to 40 cents of every revenue dollar reached operating profit, after 41.2% in FY2024 (per company filings).
Growth Catalysts
Where the Next Dollar Comes From
Paycor took Paychex up-market. The FY2025 acquisition opened the mid-market and enterprise HR software segment and added scheduling, workforce management and talent capability (per company disclosures). Management guided FY2026 total revenue growth of 16.5% to 18.5%, Management Solutions growth of 20% to 22%, and adjusted operating margin of about 43% (company guidance).
- WISE AI Platform. Announced in May 2026 and built for what the company calls an agentic digital workforce: software agents that carry out HR and payroll workflows with limited human involvement (company announcements).
- AI inside the products already sold. Paycor Smart Scheduler and Paychex Flex Time arrived in February 2026, after a December 2025 suite aimed at putting enterprise-grade tools in front of smaller employers (company announcements).
- A margin case as well as a product one. Employee costs are about 55% of cost-of-service revenue, so automating routine filing and support work represents potential margin upside (per Bloomberg research).
Historical Context
FY2021 – FY2026E Revenue Trajectory
~8.2% revenue CAGR (FY2021–FY2025)
Paychex closes its fiscal year on May 31, so FY2021 covers the year to May 2021. Revenue rose in each of the five reported years shown, through the hiring disruption of 2020 and 2021 and the rate cycle that followed. Adjusted earnings per share compounded faster, at about 13.1% a year. The FY2026 bar is expectation, not result (company guidance and Bloomberg consensus estimates).
FY2021: $4.06B
FY2022: $4.61B
FY2023: $5.01B
FY2024: $5.28B (margin peak)
FY2025: $5.57B
FY2026E: $6.51B (Paycor year)
• Adjusted EPS (FY2021–FY2025): $3.04 → $4.98, +64%
• Quarterly dividend (FY2023–FY2026): $0.79 → $1.19, +51%
• Free cash flow (FY2021–FY2025): $1.15B → $1.71B, +49%

Payroll runs whether the quarter was good or bad. Paychex bills each time it runs.
Valuation & Investment Thesis
Priced for Continued Growth
What ~20× Forward Earnings Buys
Paychex trades at ~20× forward earnings (NTM) against ~22× trailing, and trailing earnings still carry the Paycor charges that pulled quarterly earnings per share to $0.82 against a $1.18 consensus in the quarter ended May 2025 (Bloomberg consensus estimates).
What it buys is a fee base that re-bills every pay period at better than 70% gross margin, priced at roughly a 5% discount to the HR software peer group on slower organic growth (per Bloomberg research). Consensus has earnings per share at $4.97 in FY2026 and $5.73 in FY2027, and a return of margins toward FY2024 levels represents further upside (Bloomberg consensus estimates).
Key Risks
What Could Change the Story
- Labor market sensitivity, since fees follow how many people clients employ, and volumes, client counts and interest income all fall in a downturn.
- Small-client exposure, higher than at ADP, with bankruptcies and financial distress among the smallest clients cited in FY2025 commentary (per Bloomberg research).
- Paycor integration, where sales force reshuffling and integration complexity left organic growth below expectations in the quarter ended May 2025.
- Leverage, with total debt rising from ~$886M to ~$5.0B and net debt of $3.4B after the acquisition, against a historically net-cash balance sheet.
- Competition and regulation, as cloud-native HR platforms keep gaining share and payroll tax or benefits rule changes can shift demand.
What This Means For You
The Index Angle, in Plain Terms
In your index fund — If you hold a fund that tracks the Nasdaq-100 Index®, you already own this.
- Index composition follows transparent eligibility criteria, and PAYX is a current constituent at ~0.19% index weight: roughly 19 cents of every $100 tracking the Nasdaq-100 sits in Paychex.
- You may have met the company on a pay stub. Paychex produces payroll, tax forms and retirement plan statements for about 800,000 mostly small and mid-sized employers.
- It is classified in industrials rather than technology. Nasdaq indexes use the ICB scheme, which places Paychex in commercial support services with other business-service companies.
Decoding the Jargon
Two terms doing the heavy lifting in this issue.
- PEO (professional employer organization). Paychex becomes the co-employer of record for a client's staff and takes on payroll, workers' compensation and health insurance administration. With insurance products it is the smaller of the two reported segments.
- Interest on client funds, the payroll float. Money sits with Paychex briefly between a client funding payroll and wages and taxes going out, and earns interest along the way. That came to about $45.2M in the quarter ended May 2025, so rates move a small piece of the revenue line (per Bloomberg research).
Bottom Line
Inside the Nasdaq-100®, Paychex is paid on a payroll calendar rather than a sales cycle. Its growth depends on how many people its clients employ.
