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.

Price Behavior

7.0

Key Price Behavior Insights: • Modest uptrend • Momentum intact • Resistance stall risk Support Level: $284–$286, deeper at $269.08 Resistance Level: $297.15 CLH sits modestly above its last month SMA (~$285.7) with RSI ~61, suggesting constructive momentum toward the $297 resistance but failure to clear $297 could trigger mean reversion toward the $284–$286 band or $269.08 support.

Sentiment & News

7.0

Key News Insights: • Earnings beat • Strategic acquisition • Rising capex Clean Harbors topped Q4 and FY25 estimates, closed a ~$130M industrial acquisition and raised investor engagement, driving a 52-week high amid analyst upgrades but offset by rising capex and mixed investor positioning.

AI Summary

7.0
Positive

Clean Harbors has shifted from a defensive waste hauler to a capital‑intensive specialist whose valuation now hinges on management executing large capex/M&A (notably the SDA build and Depot Connect integration) to convert record FCF into scalable EBITDA. Monitor SDA project milestones, PFAS multi‑year contract conversion, and net debt/EBITDA trends—misses or capex overruns would amplify refinancing and valuation downside.
