PAYC (Paycom Software) — Investment Thesis #

Scored 2026-03-22 | Price: $124.82 | Composite: 3.0/5 (15/25)

Hypothesis #

Paycom is a high-quality HCM SaaS franchise (87% gross margins, ~39% EBITDA margins, 91% retention) that has drawn down 53% from its 52-week high to a forward P/E of 10.9x — implying only 1.2% perpetual growth needed to justify the price. The Growth Stock Addendum (shr-004) shows this passes easily: even 5% sustainable growth yields 41% margin of safety on forward earnings.

However, per shr-002, systematic C-suite insider selling ($50M+ across CEO, COO, CFO, CTO with zero open-market purchases) is disqualifying for entry. When every senior insider with informational advantage is selling into a declining stock, the market's negative price signal is likely correct. This thesis is placed on the watchlist pending insider signal reversal.

Why This Would Be Good (If Insiders Weren't Selling) #

The valuation #

• Forward P/E: 10.9x for an 87% gross margin, recurring-revenue SaaS business with no financial debt
• Break-even growth (forward): 1.2% — the bar is almost on the floor
• Graham IV at 5% growth (forward): $211 → 41% margin of safety
• SBC-adjusted P/FCF: 23.3x (per shr-001: reported 16.4x is misleading)

The franchise quality #

• Gross margins: 87% (best-in-class HCM)
• EBITDA margins: 38.9% (FY2025)
• Revenue retention: 91% (management-reported)
• Revenue: $2.05B (+9% YoY)
• Total debt: $61.9M (all capital leases — zero financial debt)

The Growth Stock Addendum (shr-004) #

At forward P/E 10.9x, implied growth is 1.2%/year. Historical growth: 23% → 11% → 9% (decelerating but still far above implied). Per shr-004: "buy only when implied growth is ≤ the growth rate you believe is achievable, with margin." Even at 5% sustainable growth (far below historical), the stock has significant margin of safety.

Why It's On The Watchlist, Not A Buy #

The insider signal (shr-002) — DISQUALIFYING #

Per shr-002: "Systematic insider selling across multiple C-suite officers (CEO + COO + CFO + CTO) is a far stronger bearish signal than any single insider selling." This is exactly that configuration.

Per Paleologo Ch. 13.3: when agents with superior information (insiders) are taking the opposite side of your trade, your parameter estimates are almost certainly worse than theirs. The mathematically optimal position size is zero until the information asymmetry resolves.

Other concerns #

• SBC consumes 29% of FCF (shr-001) — reported $408M FCF becomes $285M after SBC
• EPS declined 9.4% in FY2025 despite 9% revenue growth — G&A surged 76% ($159M → $279M)
• Revenue growth decelerating: 23% → 11% → 9% over three years
• The 76% G&A surge is unexplained — if structural (not temporary), the earnings inflection thesis fails

Upgrade Conditions (Watchlist → Stage 2) #

Must satisfy BOTH:

1. Insider buying: At least one C-suite officer makes an open-market purchase of $100K+
2. G&A normalization: Next earnings report shows G&A returning toward $160-180M annual run rate (from $279M in FY2025)

If both conditions are met: upgrade to Stage 2, re-score, and enter at half-Kelly.
