Clean Harbors (CLH) Stock Forecast & Price Target

Clean Harbors is supported by strong execution across Environmental Services and Safety-Kleen Sustainability Solutions, with Q3 revenue up 16%, adjusted EBITDA up 42.5% year over year to $456M, and EPS of $3.93 versus $3.21 expected. Its outlook is reinforced by raised FY26 adjusted EBITDA guidance to $1.44B-$1.48B and free cash flow guidance to $600M-$660M, alongside a conservative midpoint that leaves room for upside. The company also benefits from a widening moat in hazardous waste, momentum from reshoring, PFAS regulation, data center investment, and M&A-driven pricing and margin expansion.

Clean Harbors is exposed to multiple fundamental headwinds that could pressure margins and cash flow, including stronger union bargaining power, tighter federal, state, and local regulation, and stricter controls on hazardous waste handling that raise operating costs. Its acquisition-led growth strategy also creates vulnerability to higher interest rates, which can make M&A less attractive, increase interest expense on substantial debt, and reduce access to capital. In addition, integration risk and operational mishaps such as truck accidents, facility fires, or landfill leaks could trigger fines, losses, and reputational damage, reinforcing a negative outlook.
