The companies
AYIAcuity Inc.
Why now
Electrical Equipment & Parts · market cap $10.0b. 12% off the 52-week high of $380.17. Revenue growing +10%, comfortably above the S&P median. 7 sell-side analysts rate this a Buy with a mean 1-yr target of $398.29 (implying +19% upside).
Moat
ROE 17% sits above Buffett's preferred 15% threshold — the equity base is compounding at a rate the market struggles to discount accurately. FCF converts 135% of net income — earnings translate cleanly into cash, a sign that working capital and capex are well-disciplined.
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.
PNRPentair plc
Why now
Specialty Industrial Machinery · market cap $10.8b. Down 42% from 52-week high of $113.95 — deep drawdown territory. 14 sell-side analysts rate this a Buy with a mean 1-yr target of $79.43 (implying +19% upside).
Moat
Net margin 16% beats the market median by a meaningful margin — the company is keeping more of every revenue dollar than the average S&P constituent. ROE 18% sits above Buffett's preferred 15% threshold — the equity base is compounding at a rate the market struggles to discount accurately. FCF converts 107% of net income — earnings translate cleanly into cash, a sign that working capital and capex are well-disciplined.
Risk
Down 42% from the 52-week high — the market is pricing in something the screen can't see; verify the bear case before sizing up.
