About Clean Harbors
Clean Harbors provides environmental and industrial services throughout North America, handling waste from the point it is generated through final treatment or disposal. It works across hazardous and non-hazardous materials, using methods such as incineration, secure landfilling, wastewater treatment, fuel blending and resource recovery, and it is particularly known for its CleanPack offering, which handles sensitive laboratory chemicals through careful packaging and disposal. The company also carries out industrial maintenance and on-site field work using its own equipment and crews.
Its operations are split into two segments. Environmental Services covers the broader waste lifecycle described above, while Safety-Kleen Sustainability Solutions focuses on parts washers, cleaning products such as degreasers, antifreeze and hand sanitizers, and related supplies like absorbents and spill kits. This second segment also collects containerized and vacuum waste from oil and water separators, sumps and tanks, gathers used fluids from manufacturing, automotive and metal fabrication sites, and produces and distributes lubricants along with custom blending and packaging services.
Clean Harbors was founded in 1980 and is headquartered in Norwell, Massachusetts. Its shares are listed on the NYSE under the ticker CLH.

Last earnings call, Jul 29, 2026 AI summary
- What they said
- Clean Harbors reported a strong Q2 2026 driven by record revenue, adjusted EBITDA and adjusted EBITDA margin, led by exceptional performance in Safety-Kleen Sustainability Solutions (SKSS) and continued strength in Environmental Services (ES). Management highlighted safety performance, strong utilization of disposal assets and expanding margins across ES, and an SKSS spike driven by global lubricant/base-oil dynamics and closed-loop product demand. Key strategic initiatives include a definitive agreement to acquire ES&H for $305 million to expand Field Services in the Gulf region, accelerated investments in data-center services (targeting $50 million of CapEx across the initiative), VAC truck expansion (~$25 million over two years), continued Kimball incinerator ramp (expected ~$10 million of EBITDA), and a multi-year pipeline for PFAS remediation and treatment projects. Financial highlights: Q2 revenue $1.74 billion (+12% YoY), adjusted EBITDA $409 million (+22% YoY), adjusted EBITDA margin 23.6% (company record), EPS $3.22. Management raised full-year guidance modestly (net ~$30 million higher vs prior guide) with notable SKSS guide uplift. Balance sheet: cash & short-term investments $517 million to support M&A and capital allocation. Management pointed to pipeline growth, market share gains across waste volumes, and strategic investments to drive mid- to long-term growth.
- Guidance
- - Full-year guide raised by approximately $30 million versus prior guide (management referenced ~+$30M full-year increase). - SKSS full-year adjusted EBITDA guide implied at $275 million (up from prior $165 million guidance referenced by analyst). - D&A guidance for 2026: $475 million to $485 million. - SG&A expected to be in the mid- to high-12% of revenue range for full-year 2026. - Kimball incinerator incremental EBITDA: approximately $10 million (baked into guide). - Acquisition ES&H expected to contribute approximately $90 million of revenue and ~$30 million of adjusted EBITDA on an annual basis; expected cost synergies of ~$5 million after first full year. - Data center initiative: current-year revenue ~$15–20 million; target run rate of ~$200M+ by 2029. (Note: acquisition closing subject to regulatory approvals; guidance based on management assumptions.)
- Risks flagged
- - Cyclicality and commodity-price exposure in SKSS (base oil pricing and re-refining spreads can materially affect EBITDA). - Dependence on refinery turnaround timing and broader industrial-activity cycles (turnaround deferrals could delay Industrial Services upside). - Regulatory and execution risk on M&A (ES&H closing subject to approval) and on large projects (PFAS, major manufacturing contracts). - Competitive dynamics for oil/charge-for-oil when base oil economics change. - Operational/insurance/claim related cost increases (SG&A pressure noted). - PFAS remediation outcomes are partially dependent on regulatory frameworks and governmental timelines.
