Stronger-than-expected Q4 results, an accretive $130M Depot Connect acquisition announced 2026-02-19, and solid cash generation have driven a short-term breakout (~8% over a month, above the 21-day SMA); upcoming investor commentary (e.g., 3/3 conference) can reinforce the move for further near-term gains.

Valuation Metrics
Fundamental Analysis
Key Financial Insights: ⢠Strong cash generation ⢠Moderate leverage ⢠High valuation CLH delivers solid profitability, strong cash flow, and comfortable liquidity, but its meaningful leverage and rich valuation limit upside and increase downside risk.
Price Behavior
Key Price Behavior Insights: ⢠Uptrend intact ⢠$300 support ⢠$310 breakout needed Support Level: $300 Resistance Level: $308-$310 CLH has shown a positive trend over the last month, but with choppy trading and near-term resistance in the $308-$310 area, so a clean breakout above $310 is needed to confirm more upside.
Sentiment & News
Key News Insights: ⢠PFAS Demand ⢠Analyst Upgrades ⢠Margin Pressure Clean Harbors is drawing bullish analyst attention on strong PFAS-driven growth prospects and strategic momentum, though rising costs and execution risk remain key watchpoints.
AI Summary
CLH should now be viewed less as a steady defensive compounder and more as a PFAS-led growth platform with strong free cash flow and acquisition/buyback optionality, but the premium valuation means the stock likely needs clean execution on PFAS, Depot Connect integration, and margin control to justify further upside.
