FCF$569mTTM · 03/26
C+
FCF $569m — respectable but not differentiating · TTM computed from 4 most-recent quarters (TTM · 03/26).
Rev+5.0%TTM YoY
C+
Revenue +5.0% — steady but below market-beating range · TTM YoY from trailing-4-quarter revenue sum vs prior 4 quarters.
D/E0.87total
B
D/E 0.87 — at market average, manageable · Total D/E computed from balance sheet (short-term + long-term debt + lease obligations) ÷ stockholders equity. More accurate than native field, which often uses long-term debt only.
P/E23.4x
B
P/E 23.4 — moderate premium, defensible with growth
PEG4.64proxy
D
PEG 4.64 — very expensive; pricing in best-case scenarios · PEG proxy: P/E ÷ revenue growth % (true PEG requires forward EPS estimates, not in Finnhub free tier).
Why now
Building · market cap $10.3b. Down 26% from 52-week high of $179.31 — deep drawdown territory.
Moat
Net margin 14% beats the market median by a meaningful margin — the company is keeping more of every revenue dollar than the average S&P constituent. ROE 22% sits above Buffett's preferred 15% threshold — the equity base is compounding at a rate the market struggles to discount accurately.
Risk
Mature compounder — the risk is paying up for quality at a moment when growth is decelerating. Watch for sequential revenue + margin trends; the inflection from "compounder" to "ex-compounder" is hard to spot until the multiple already started compressing.
Horizon
1-3 yr $152.95 (structural (no analyst coverage)) — fundamentals + valuation re-rating. 5 yr $214.20 at ~10% CAGR — compounding case rests on the competitive position widening. 10 yr $314.86 if current growth sustains into durable earnings power.
