Automatic Data Processing Inc (ADP) - Stock Report

The key macro issue is not lower rates alone, but whether lower client-funds reinvestment yields arrive while payroll volumes stay healthy: if positive pays per control, retention and productivity hold, ADP can turn float income into durable post-capex cash; if employment softens at the same time, the same payroll base carries less high-margin interest income and weaker operating leverage.

ADP's latest reported quarter supports that test. In Q3 FY2026, revenue rose 7% to $5.9 billion, reported diluted EPS rose 10% to $3.38, and adjusted diluted EPS rose 10% to $3.37, with reported and adjusted net earnings both near $1.4 billion. Adjusted EBIT increased 10% to $1.8 billion and adjusted EBIT margin expanded 80 bps to 30.2%. Employer Services carried the quality bridge: revenue rose 7%, U.S. pays per control increased 1%, and segment margin expanded 130 bps. PEO revenue also rose 7%, but its segment margin fell 120 bps, so the co-employment engine is adding scale without the same margin lift. Client-funds economics remained material: interest on funds held for clients rose 14% to $404 million as average client-funds balances increased 9% to $48.3 billion and yield rose 10 bps to 3.3%. Management also raised FY2026 guidance to revenue growth of 6%-7%, adjusted EBIT margin expansion of 70-80 bps, and reported and adjusted diluted EPS growth of 10%-11%.

ADP is a payroll, tax-compliance and human-capital-management operator whose software is tied to money movement. Its core systems calculate wages, withholdings, tax filings, benefits and HR records for employers that cannot tolerate payroll failure. The value stack is therefore broader than an application interface: ADP combines payroll processing, regulatory updates, employer-of-record-style PEO administration, benefits workflows, implementation support, and client-funds investment income.

Employer Services is the primary franchise. It serves employers through RUN, Workforce Now, Lyric, Global Payroll, SmartCompliance and related HR outsourcing modules. This segment owns the higher-quality bridge because payroll accuracy, tax compliance and switching friction support recurring revenue and pricing, while the client-funds float adds a financial-infrastructure layer when balances and rates cooperate.

PEO Services, mainly ADP TotalSource, is economically different. It provides co-employment, benefits administration, workers' compensation and HR outsourcing. That deepens client attachment and broadens wallet share, but the reported revenue line includes zero-margin benefits pass-throughs, so PEO revenue growth must be judged against worksite employee growth, pass-through mix and segment margin, not just headline scale.
