The companies
CLHClean Harbors, Inc.
Why now
Waste Management · market cap $16.4b. 7% off the 52-week high of $335.94. PEG 0.27 — paying under fair value for the growth rate. 15 sell-side analysts rate this a Buy with a mean 1-yr target of $358.93 (implying +15% upside).
Moat
ROE 14% meets the long-run market sustainable threshold — solid but not differentiated; the durability comes from elsewhere. FCF converts 118% of net income — earnings translate cleanly into cash, a sign that working capital and capex are well-disciplined.
Risk
Trailing P/E 38x sits well above the S&P median (~20x) — multiple compression is a real risk if revenue growth decelerates.
ZWSZurn Elkay Water Solutions Corporation
Why now
Pollution & Treatment Controls · market cap $8.8b. 4% off the 52-week high of $55.00. Revenue growing +10%, comfortably above the S&P median. 10 sell-side analysts rate this a Buy with a mean 1-yr target of $58.10 (implying +10% upside).
Moat
Net margin 12% beats the market median by a meaningful margin — the company is keeping more of every revenue dollar than the average S&P constituent. ROE 13% meets the long-run market sustainable threshold — solid but not differentiated; the durability comes from elsewhere. FCF converts 145% of net income — earnings translate cleanly into cash, a sign that working capital and capex are well-disciplined.
Risk
Trailing P/E 33x sits well above the S&P median (~20x) — multiple compression is a real risk if revenue growth decelerates.
