AI Summary

6.0
Neutral

CLH's strong core execution is increasingly overshadowed by a debt-funded acquisition pivot, making post-EnviroServe integration, free-cash-flow conversion, and returns above its 6.25% funding cost the decisive investment tests; investors should remain selective at the elevated valuation until acquired earnings and margins validate the strategy.
