Clean Harbors (CLH) Stock Forecast: What Could Drive It in 2026
Last updated July 2026
Short answer
What is actually driving Clean Harbors (CLH) right now is Scarce disposal infrastructure and pricing power: Clean Harbors owns a network of RCRA-permitted incinerators and hazardous-waste landfills that are extremely difficult to permit and build new. Revenue (FY2025) is ~$6.03B. If that keeps playing out, the setup is favourable; the risk to it is the stock trades at roughly 40x trailing earnings, so it prices in continued execution and leaves little room for disappointment. No one can predict where CLH trades, and Walnut does not publish targets, so treat this as a scenario, not a price target or prediction.
What could drive Clean Harbors (CLH) higher?
1. Scarce disposal infrastructure and pricing power
Clean Harbors owns a network of RCRA-permitted incinerators and hazardous-waste landfills that are extremely difficult to permit and build new. This scarcity underpins consistent annual price increases on the disposal side and structurally supports Environmental Services margins, the segment that drives most of the company's profit.
2. New incinerator capacity and utilization
The Kimball, Nebraska incinerator adds meaningful high-margin disposal capacity as it ramps toward full utilization. Incremental incineration volumes flow through at strong margins, so rising utilization is a core lever for adjusted EBITDA growth over the next several years.
3. PFAS destruction opportunity
Clean Harbors has positioned itself as a leader in destroying PFAS (so-called forever chemicals) via high-temperature incineration, with study results the company says surpass EPA standards. As federal and corporate PFAS rules tighten, this could become a multi-year revenue and margin tailwind, with management describing a rapidly growing services pipeline.
4. Recurring revenue and reshoring tailwinds
A large share of revenue is recurring, tied to ongoing industrial production, maintenance turnarounds, and regulated waste generation. Reshoring of US manufacturing and continued industrial activity expand the base of waste that must be managed, supporting the Environmental Services growth trajectory.
What could weigh on CLH?
The stock trades at roughly 40x trailing earnings, so it prices in continued execution and leaves little room for disappointment. The SKSS segment is sensitive to base and blended oil pricing, which pressured results in early 2026 and adds cyclicality. Environmental Services demand is tied to industrial production and energy activity, so a manufacturing or energy slowdown would reduce waste volumes and emergency-response work. The business is capital intensive and carries meaningful debt from acquisitions, and it faces ongoing regulatory, environmental-liability, and permitting risk. PFAS revenue, while promising, is still early and depends on the pace and shape of future regulation.
