ADP Plummets 5.1%: Earnings Optimism Crumbles as Core Metrics Signal Deterioration

Summary
• ADP’s Q1 earnings report revealed a 29% surge in float income but flat U.S. pays per control.
• Operating cash flow fell 22% YoY to $642M, while PEO Services margin contracted 140 bps.
• Options volume spiked on 11/7 expirations, with 654,500 shares traded on the 260-strike put.

Automatic Data Processing (ADP) plunged 5.1% to $265.30, erasing a $14.33 intraday loss as core operational weakness overshadowed float income gains. The stock traded between $262.40 and $272.56, reflecting a volatile session driven by earnings-driven margin compression and sector-wide HR services pressure.

Float Income Surge Masks Core Operational Weakness
ADP’s 7% adjusted EPS growth hinged entirely on a 29% jump in float income to $264M, while core metrics crumbled. U.S. pays per control—a proxy for employment growth—flatlined at 0%, signaling a collapse in organic demand for Employer Services. PEO Services margins contracted 140 bps to 13.0% due to 8.5% spikes in workers’ comp costs. The stock’s 5.1% drop reflects investor skepticism about the sustainability of interest rate-driven float income and deteriorating service margins.

Human Resource & Employment Services Sector Under Pressure as PAYX Slides 4.24%
The HR services sector mirrored ADP’s weakness, with Paychex (PAYX) down 4.24% on concerns over AI-driven job displacement and rising compliance costs. ADP’s 5.1% decline outpaced PAYX’s drop, reflecting deeper margin pressures in PEO services and operating cash flow deterioration. Sector-wide, layoffs and AI integration fears amplified risk aversion, dragging down valuations across the board.
