ADP — Automatic Data Processing, Inc.

The market is optimistic after fiscal Q4 2026 earnings and a ~14% 30-day rally; several banks raised targets to $280-$310. However, the consensus rating remains Hold and the average target is below the current price, so the bullish price action is running ahead of analyst conviction.

Revenue growth has been stable at roughly 6-7% YoY for the last 8 quarters; FY26 revenue was ~$21.95B, up 6.7%. FY26 EPS came in around $10.97, up ~8.2% from FY25. Margins are muddy: TTM operating margin fell to 18.6% from 26.3% largely because of an unusual $122.5M operating loss in the Sep-2025 quarter, while Q4 FY26's operating margin still contracted to 20.8% from 23.5% a year earlier. Net margins and FCF conversion remain healthy, but FY27 revenue guidance of ~5% growth is a clear deceleration, not an acceleration.

At $284.68 as of 2026-08-27, ADP trades at 25.95x trailing EPS, just below its 5-year average of 26.69x, and at ~23.2x forward FY27 EPS of $12.258. P/S of 5.19x is slightly above its 5-year average of 5.12x, and a PEG of 2.7x is high for a ~6% grower. That is fair-to-slightly-rich — not cheap, and with little margin of safety versus the $267.67 consensus target.

The market is pricing in continued steady execution and high-single-digit EPS growth that is ahead of the ~5% revenue guidance; the FY27 EPS estimate of $12.258 implies ~10.9% earnings growth, which would require margin expansion or extra buybacks. If ADP simply hits guidance, shares are roughly fairly valued around $270; if it beats and raises guidance, the $300+ high targets come into play. At $284.68, buyers are paying for the beat before it happens.

As of 2026-08-27, RSI stood at 67.14 — strong but approaching overbought. Price was 3.72% above the 20-day, 12.0% above the 50-day, and 20.55% above the 200-day SMA, so the trend is firmly up but extended after the post-earnings run. Chasing here is poor risk/reward; a pullback toward the 50-day or 200-day would offer a better entry.

• Labor market is stable but moderating: July private payrolls of only +44k limit volume growth, though ADP's retention at 92.1% provides a floor.
• Interest rates and Treasury yields directly affect high-margin client-fund float income; rate cuts would pressure that earnings tailwind.
• Increasing tax/regulatory complexity is an adoption tailwind for SmartCompliance and raises switching costs.
• AI-driven HCM competition (Workday, UKG, etc.) is forcing ADP to invest, but also supports upmarket Lyric HCM momentum.
• Defensive/slow-growth dividend payers remain in favor in uncertain markets, supporting valuation even without strong fundamental growth.

• Q1 FY27 earnings expected late Oct/early Nov 2026 — first evidence on whether ~5% revenue guidance is conservative or weak.
• Ex-dividend date September 11, 2026 ($1.70 quarterly dividend) could bring income-driven buying.
• Monthly ADP National Employment Report and NER Pulse prints give real-time labor-market signal for payroll volumes.
• AI/compliance product launches and enterprise wins on Lyric HCM could drive above-guidance new bookings.

• Decelerating revenue growth: FY27 guidance of ~5% is below FY26's 6.7%, and the stock's multiple leaves no room for a miss.
• Labor-market downturn would directly reduce payroll volumes, PEO worksite employees, and new bookings.
• Rate cuts would compress client-fund interest income, historically a high-margin contributor.
• Margin trend is already pressured by a one-off charge and Q4 compression; if it keeps slipping, EPS growth and the premium multiple are at risk.

ADP is a high-quality, wide-moat compounder with 23.9% ROIC, 20.1% net margin, and ~$5.0B of TTM free cash flow. But as of 2026-08-27 the stock has run ahead of the fundamentals — growth is slowing, margins are mixed, and the forward P/E offers no cushion — so this is a good business at the wrong price; the risk/reward favors waiting for a pullback rather than buying here.

I applied a 22.0x justified P/E multiple to consensus FY27 EPS of $12.258, a deliberate discount to ADP's 5-year average trailing P/E of 26.69x and its ~23.2x current forward P/E because revenue growth is decelerating toward ~5%. This yields $269.68, slightly below the current price and in line with a fair-value read of the fundamentals.
