The companies
EXPOExponent, Inc.
Why now
Engineering & Construction · market cap $3.2b. 20% off the 52-week high of $81.95. 3 sell-side analysts publish a mean 1-yr target of $81.67 (implying +24% upside).
Moat
Net margin 18% beats the market median by a meaningful margin — the company is keeping more of every revenue dollar than the average S&P constituent. ROE 32% — top-decile capital efficiency. Either pricing leverage, low capital intensity, or aggressive buybacks; the durability story depends on which. FCF converts 104% of net income — earnings translate cleanly into cash, a sign that working capital and capex are well-disciplined.
Risk
Trailing P/E 31x sits well above the S&P median (~20x) — multiple compression is a real risk if revenue growth decelerates.
PRIMPrimoris Services Corporation
Why now
Engineering & Construction · market cap $4.1b. Down 64% from 52-week high of $205.50 — deep drawdown territory. Revenue growing +13%, comfortably above the S&P median. 14 sell-side analysts rate this a Buy with a mean 1-yr target of $127.50 (implying +71% upside).
Moat
ROE 15% meets the long-run market sustainable threshold — solid but not differentiated; the durability comes from elsewhere.
Risk
Down 64% from the 52-week high — the market is pricing in something the screen can't see; verify the bear case before sizing up. Beta 1.42 implies above-market volatility — position-size to the drawdowns this name will produce in a market correction, not to its bull-case return. Net margin 3.3% is thin — operating leverage cuts both ways; input-cost inflation or pricing pressure hits the bottom line first.
