AI Summary

6.0
Neutral

CLH now looks like a high-quality scarce-infrastructure franchise with improving cash flow, but the stock already discounts that strength, so upside depends on Terra Nova integration and sustained margin execution rather than faster revenue growth, with valuation leaving little room for disappointment.
