Automatic Data Processing (ADP) — Company Research

Last Updated: 14 August 2026

Automatic Data Processing is the largest payroll and human capital management provider in the world, paying more than 42 million workers across 140-plus countries and territories. It closed fiscal 2026 on 30 June with revenue of $21.95bn, up 7%, and adjusted diluted earnings per share of $11.12, up 11% — the company's twentieth consecutive year of revenue growth and the year in which its board approved a fifty-first consecutive annual dividend increase. This report sets out what ADP owns, how the money actually arrives, the five-year financial record drawn from the company's own filings, and the raw valuation arithmetic. It contains no analyst price targets and no third-party ratings.

1. Company Snapshot

2. Bull and Bear Case

Bull Case

• Scale that is genuinely hard to replicate: ADP pays more than 42 million workers, moved $3.5 trillion of client funds in fiscal 2026 and issued over 79 million year-end US employee tax statements. Payroll compliance across 140-plus jurisdictions is a regulatory obligation, not a discretionary purchase, and the switching cost of moving it is high.
• Float income is now a $1.35bn profit engine: Interest on funds held for clients reached $1,354.8m in fiscal 2026, up 14%, on average client fund balances of $40.4bn at an average yield of 3.4%. Management guides that yield to roughly 3.7% in fiscal 2027 on balances growing 3–4%, taking interest income to $1.540–1.560bn. This income requires no incremental headcount.
• Margins are still expanding: Employer Services segment margin reached 36.7% in fiscal 2026, up 60 basis points, and management has guided consolidated adjusted EBIT margin expansion of a further 70–90 basis points in fiscal 2027 alongside 5–6% revenue growth and 9–11% adjusted EPS growth.
• A dividend record almost no company can match: The board approved its fifty-first consecutive annual increase in November 2025, lifting the quarterly rate 10% to $1.70. ADP paid $2,626.3m of dividends and repurchased $2,083.3m of stock in fiscal 2026, with $4.86bn still available under the $6bn authorisation approved in January 2026, all supported by AA- rated credit.
• The enterprise push has real product behind it: Lyric HCM now carries the WorkForce Software suite acquired in October 2024 and the ADP Assist agentic AI layer, giving ADP a credible large-enterprise offering against cloud-native rivals. Research and development spending was $1,405m in fiscal 2026.

Bear Case

• The engine that drives organic growth has stalled: US pays per control — same-store employment at ADP's existing clients — grew just 1% in fiscal 2026, and management guides 0–1% for fiscal 2027. ADP's volume growth is a direct function of American hiring, and American hiring is barely positive.
• Retention is guided to go backwards: Employer Services client revenue retention was 92.1% in fiscal 2026, flat year on year, and management explicitly guides a decline of 10 to 30 basis points in fiscal 2027. Small movements in retention compound heavily in a subscription base this large.
• Float income cuts both ways: The $1.35bn of client-funds interest that flattered fiscal 2026 is a function of the rate cycle. ADP's fiscal 2027 assumptions rest on forward curves as at 28 July 2026 and a 4.4% blended new-purchase rate; a faster easing cycle, or a fall in employment that shrinks the $40.4bn of balances, removes profit that carries essentially no cost.
• Competition is sharper at the top and the bottom: Workday, Paycom and Paylocity compete directly for the mid-market and enterprise seats ADP wants most, and the 10-K names cloud HCM providers, ERP vendors and financial institutions as competitors. Dayforce's take-private by Thoma Bravo in February 2026 removes a listed comparator but not a competitor.
• The multiple assumes the compounding continues: At roughly 25 times trailing GAAP earnings for a business guiding 5–6% revenue growth, the shares price in uninterrupted execution. A restructuring charge of $91.1m was booked in the fourth quarter for a new corporate business alignment programme, a reminder that even ADP has to work at its cost base.

3. Business Segments

ADP reports two operating segments. Figures below are for fiscal 2026, the year ended 30 June 2026, and reconcile to total revenue of $21,947.4m.

4. Business Model and Moat

How it makes money. ADP earns revenue three ways. First, recurring per-employee-per-period fees for payroll and HCM software and outsourced services in Employer Services. Second, PEO service fees, where ADP co-employs roughly 762,000 worksite employees and bundles benefits, workers' compensation and unemployment insurance — a business that carries $718.4m of embedded workers' compensation and state unemployment costs. Third, and less visibly, interest on the money it holds. Because ADP collects payroll and tax funds from clients before remitting them to employees and tax authorities, it sits on an average balance of $40.4bn, which it invests through an extended-duration ladder. That produced $1,354.8m of interest income in fiscal 2026 and a net contribution of $1,314.6m after short-term financing costs, up 22%.

Why clients stay. Payroll is the one system an employer cannot afford to have fail. Employer Services client revenue retention was 92.1% in fiscal 2026 and estimated average client tenure is roughly 13 years in Employer Services and 6 years in PEO. The moat is a compound of regulatory complexity across more than 140 jurisdictions, integration into general ledgers, benefits carriers and time systems, and the simple operational reality that migrating payroll mid-year is painful. Scale then reinforces itself: ADP amortises compliance engineering for 60-plus statutory jurisdictions across 1.1 million clients, which a subscale competitor cannot.

Where the leverage sits. The float is the quiet source of operating leverage. Interest income scales with rates and balances but requires no additional service delivery, which is why fiscal 2026 saw revenue up 7% and adjusted EPS up 11%. The corollary, covered in the bear case, is that the same line contracts without warning when the rate cycle turns.

5. Financial Health

All figures below are taken from ADP's quarterly earnings releases, Form 10-K filings and SEC XBRL company facts. ADP's fiscal year ends on 30 June, so fiscal 2026 covers 1 July 2025 to 30 June 2026. Adjusted figures are ADP's own non-GAAP measures, which exclude items such as transformation initiative costs, gains and losses on business divestitures and certain legal settlements.

Revenue compounded at 7.4% a year over the four-year span from fiscal 2022 to fiscal 2026. Dividends declared per share compounded at 13.1% a year over the same period, roughly double the revenue rate, funded by margin expansion and a falling share count. Long-term debt rose from $2.99bn to $4.96bn across the period, principally to fund the WorkForce Software acquisition in fiscal 2025 and general corporate purposes; at 0.8 times fiscal 2026 EBITDA it remains modest, and ADP carries AA- ratings from S&P and Fitch.

† Q1 and Q2 fiscal 2026 revenue is stated to the nearest $0.1bn as presented in the respective quarterly earnings releases; Q3, Q4 and the full year are stated to $0.1m as reported. The four quarterly GAAP EPS figures sum exactly to the $10.94 full-year figure, and the four adjusted figures to $11.12.

Cash generation. Operating cash flow was $5,441.2m in fiscal 2026, up 10% from $4,939.7m. Capital expenditure on property and equipment was $196.6m and purchases of intangible assets, principally capitalised software, were a further $468.5m. Depreciation and amortisation was $585.9m. Cash and cash equivalents stood at $4,230.1m at 30 June 2026 with a further $138.6m of long-term corporate marketable securities; short-term marketable securities were nil. Commercial paper outstanding, used seasonally to fund client obligations, was zero at the year end, against $4,769.5m a year earlier.

7. What Are They Building

ADP Assist. ADP's generative and agentic AI layer, embedded across its platforms and grounded in what the company describes as its own institutional payroll knowledge. It delivers persona-based agents built separately for employees, managers, HR practitioners and payroll practitioners. The scale of the underlying dataset is the point: ADP moved $3.5 trillion of client funds and processed more than 79 million year-end US employee tax statements in fiscal 2026.

ADP Lyric HCM. The flagship global cloud HCM platform aimed at large enterprises, unifying HR, payroll, workforce management, talent and analytics with ADP Assist built in. This is ADP's answer to cloud-native competition at the top of the market, and the WorkForce Software suite acquired in October 2024 was folded directly into Lyric as a unified global workforce management offering from around November 2025.

Acquisitions and spending. Fiscal 2026 was an integration year rather than an acquisition year — ADP spent just $22.8m net on businesses, against $1,165.1m in fiscal 2025 when WorkForce Software was bought. Pequity, a compensation-planning business acquired in 2025, extends the talent management suite. Research and development expenditure was $1,405m in fiscal 2026, up from $1,388m in fiscal 2025 and $1,276m in fiscal 2024, explicitly including investment in generative and agentic AI.

8. Competitive Landscape

ADP competes across an unusually wide span — from one-person payroll accounts against Paychex and Intuit, to global enterprise HCM deployments against Workday. Market capitalisations below were checked on 14 August 2026.

9. Insider Activity

Maria Black has been President and Chief Executive Officer since 1 January 2023, having been President from January 2022 and having succeeded Carlos Rodriguez. She was quoted in the fiscal 2026 results released on 29 July 2026, confirming she remains in post. Peter Hadley is Chief Financial Officer. The transactions below are drawn from Form 4 filings made with the SEC during 2026.

The pattern is unremarkable for a large-cap compounder: a director buying on a pre-arranged plan, an executive selling on a pre-arranged plan, and routine exempt administrative acquisitions. Neither the scale nor the direction of these trades carries a strong signal. Corporate-level buying has been far more significant than individual activity — ADP repurchased $2,083.3m of its own stock in fiscal 2026, with $4.86bn remaining under the $6bn authorisation approved in January 2026.

10. Key Risks

• Employment-cycle sensitivity: Revenue tracks client payroll headcount directly. US pays per control grew only 1% in fiscal 2026 and is guided to 0–1% for fiscal 2027. ADP's 10-K explicitly names a slowdown in employment levels, including as a result of AI, as a risk to results. A US recession would compress volume growth, PEO worksite employee counts and client funds balances simultaneously.
• Interest-rate exposure on client funds: The $1,354.8m of float income earned in fiscal 2026 on average balances of $40.4bn is contingent on the rate path. ADP's fiscal 2027 guidance rests on forward curves as at 28 July 2026 and a blended new-purchase rate assumption of 4.4%. A faster easing cycle would remove high-margin income, and the 10-K also flags the risk of having to sell portfolio assets at a loss.
• Client retention erosion: Employer Services client revenue retention was 92.1% in fiscal 2026 and management guides a decline of 10 to 30 basis points in fiscal 2027. Across a base of more than 1.1 million clients, sustained retention slippage would materially change the organic growth algorithm even with bookings growing.
• Cybersecurity and data breach: ADP holds payroll, tax, health, benefits and banking data for tens of millions of workers and moves $3.5 trillion of client funds annually. The 10-K discloses that the company has been and expects to continue to be the target of intrusion, ransomware, denial-of-service and insider attacks, and cites AI as accelerating attacker sophistication. A material breach would carry regulatory, litigation and reputational consequences well beyond the direct cost.
• Technological disruption from AI: ADP's own risk factors state that emerging generative and agentic AI technologies may be disruptive to the HCM industry and could render its offerings less competitive if rivals adapt faster. Payroll business process outsourcing is precisely the kind of rules-based work that automation targets.
• PEO co-employment liability and benefit costs: As a certified PEO co-employing roughly 762,000 worksite employees, ADP bears statutory employer obligations even where clients are contractually responsible. Workers' compensation and state unemployment costs embedded in PEO revenue were $718.4m in fiscal 2026, and PEO segment margin already fell 110 basis points to 13.1%. Adverse health or workers' compensation cost trends flow through directly.
• Competitive pressure at both ends of the market: Workday, Paycom, Paylocity, the now-private Dayforce, ERP vendors and financial institutions all compete for ADP's clients, and large employers retain the option of in-housing payroll entirely. Sustained share loss in the mid-market, where switching costs are lowest, would be difficult to reverse.
• Cross-border regulatory complexity: Operating in more than 140 countries exposes ADP to GDPR, the California Privacy Rights Act, the EU AI Act, the US Department of Justice Data Security Program, anti-money-laundering rules under the Bank Secrecy Act, the Foreign Corrupt Practices Act and the UK Bribery Act, plus banking supervision of ADP Trust Bank by the Office of the Comptroller of the Currency. Non-compliance in any one jurisdiction could bring fines, licence suspension or reputational damage.
