Clean Harbors raised its full-year outlook after a strong first quarter, now expecting about 9% EBITDA growth versus the 5% forecast given in February. Management said the market reaction was disappointing despite strength across most business lines.
PFAS remediation is emerging as a major long-term growth driver, with management saying recent regulatory guidance supports incineration as a scalable disposal method. Clean Harbors sees PFAS revenue growth of 25% to 35% this year and believes it can help lift environmental services margins over time.
The company also sees upside from base oil pricing, captive incinerator discussions, and share gains in field services, while industrial services remains weak. Management said potential improvement in turnaround activity could show up later in 2026 or early 2027.
Trash to Treasure: 3 Waste Removal Stocks to Minimize Volatility
Clean Harbors (NYSE:CLH) executives said the company remains optimistic about 2026 after a first-quarter guidance increase, despite what management described as a disappointing stock-market reaction to the results.
Speaking at Oppenheimer’s 21st Annual Industrial Growth Conference, Chief Financial Officer Eric Dugas said the company’s first-quarter performance showed strength across most business units, with the exception of continued difficult conditions in industrial services. Dugas said Clean Harbors raised its outlook after a “Q1 beat” and now expects consolidated EBITDA growth of about 9% for the full year, compared with the 5% growth outlook provided in February.
Time to Clean Up with These 3 Profitable Garbage Stocks
Jim Buckley, senior vice president of investor relations and communications, said the reaction was “a little bit of a head scratcher” given the company’s increased expectations. Buckley said the initial February guidance did not assume major upside from reshoring, faster PFAS growth, captive incinerator closures, a recovery in base oil prices, increased turnaround activity or large emergency responses.
Environmental Services Outlook Improves
Dugas said Clean Harbors raised its environmental services outlook by about $15 million and now expects year-over-year growth in that segment of approximately 6.5%. He cited strong performance in technical services, field services and the Safety-Kleen branch business.
In technical services, Dugas said the company continues to see good waste-stream volumes and a broader mix of waste moving through its disposal network. He also pointed to growth in retail waste, project work, remediation activity and PFAS-related opportunities.
Clean Harbors reported first-quarter incineration utilization of about 80%, including its new Kimball, Nebraska, incinerator that opened in December 2024. Dugas said the figure was somewhat below what the company had hoped but consistent with expectations, citing weather impacts and scheduled downtime. He said utilization is expected to move into the high-80% range, and potentially close to 90%, in the second and third quarters, with full-year utilization in the mid- to high-80% range.
Dugas said the new Kimball unit remains on track and is expected to handle more high-hazard waste in 2026 compared with 2025. He added that a recovery in chemical and manufacturing waste streams could improve mix and profitability.
PFAS Seen as Long-Term Growth Driver
Management spent a significant portion of the discussion on PFAS remediation and disposal, which Clean Harbors views as a major long-term opportunity. Buckley said recent guidance from regulators and government agencies validated incineration as a scalable and cost-effective PFAS disposal option, though he noted that the EPA guidance did not yet include more granular concentration thresholds.
Buckley said the company is seeing PFAS-related opportunities in contaminated water, emergency releases involving firefighting foam, airports, firehouses, industrial sites and drinking water systems. He said military-related work could unfold over “a decade plus,” with potential activity across hundreds of locations.
Dugas said PFAS growth of 25% to 35% is achievable this year, though he cautioned that timing remains difficult to predict. He said Clean Harbors has expanded work at Pearl Harbor under an existing relationship and is building relationships with military bases, private companies and communities that need PFAS cleanup.
On profitability, Dugas said PFAS projects should be margin-accretive to the environmental services segment, where the company is forecasting margins of about 27% this year. He said PFAS-related services could help Clean Harbors reach its longer-term goal of environmental services margins of 30% or higher.
Captive Incinerators and Landfill Volumes
Buckley said Clean Harbors continues to have discussions with operators of captive incinerators, which he described as major strategic decisions for those companies. He said the company is “dancing with three or four or five” potential captive operators out of 41 operating in the U.S., but emphasized that timing is hard to predict.
Dugas said some captive incinerators may operate at utilization rates as low as 30% or 40%, based on company estimates. He said upcoming regulatory requirements could prompt some operators to consider outsourcing waste management to a specialist.
Landfill volumes were also strong in the first quarter, supported by project and remediation work. Buckley said about half of annual landfill volumes typically come from projects and half from base business. He noted that landfill volumes grew 24% last year, but cautioned that project dependence makes that pace difficult to repeat every year.
Field Services Gains Share, Industrial Services Remains Soft
Dugas said Clean Harbors is taking market share in field services, helped by branch expansion, the HEPACO acquisition, improved employee retention and reduced reliance on third-party labor. He said the company has also invested in specialized equipment, including for marine responses, which improves its ability to respond to emergency response work.
Industrial services remains under pressure as refiners run at high production levels and defer turnaround work, Dugas said. He compared the current environment to the post-COVID period, when delayed maintenance eventually led to stronger activity. He said the company does not include a significant rebound in its current guidance but could see improvement in late 2026 or early 2027 if maintenance schedules normalize.
Base Oil, M&A and Buybacks
In the Safety-Kleen Sustainability Solutions business, Dugas said conflict in Iran has tightened base oil supply and lifted prices from depressed levels. He said demand from major oil customers for Group II and Group III base oils contributed to a $30 million guidance increase for that business. Additional upside could come if base oil prices remain higher for longer or if demand for Group III and direct sales expands, he said.
On capital allocation, Dugas said the acquisition pipeline is “super strong,” particularly in technical services, field services and other environmental services areas. He said valuations may have moved lower in some cases, increasing the likelihood of deals compared with a year ago.
Dugas also said Clean Harbors bought back $25 million of shares in the first quarter and will continue to evaluate repurchases alongside acquisitions and capital investments as it considers the most accretive use of capital.

Four leading AI models discuss this article
"The transition toward PFAS-related remediation provides a secular tailwind that will decouple Clean Harbors' profitability from the cyclical volatility of the broader industrial services sector."
Clean Harbors (CLH) is executing a textbook margin-expansion strategy. By pivoting toward high-barrier PFAS remediation and capturing market share in field services via the HEPACO integration, they are insulating themselves from cyclical industrial softness. The guidance hike to 9% EBITDA growth—despite stagnant industrial turnaround activity—suggests the company has higher pricing power than the market currently discounts. With incineration utilization poised to hit 90% and a 'super strong' M&A pipeline, CLH is well-positioned for a valuation re-rating. Investors are underestimating the long-term annuity-like revenue stream inherent in federal PFAS mandates, which will likely force a shift from project-based to recurring environmental service contracts.
The reliance on 'project-based' landfill volume and the speculative timing of captive incinerator outsourcing create significant earnings volatility that could trigger a multiple compression if industrial demand remains depressed through 2026.
"CLH's PFAS tailwind and incinerator capacity ramp position Environmental Services for 30%+ margins, driving re-rating despite industrial drag."
Clean Harbors (CLH) meaningfully raised FY EBITDA growth to 9% from 5% post-Q1 beat, with Environmental Services outlook up $15M to ~6.5% YoY, fueled by PFAS revenue acceleration (25-35% expected), field services market share gains via HEPACO integration and equipment, and Safety-Kleen's $30M boost from recovering base oil prices (Group II/III). Incineration utilization hit 80% in Q1 (Kimball ramping), targeting mid-high 80s full-year for 27% ES margins en route to 30%+. Strong landfill/project volumes, captive incinerator talks (3-5 prospects), M&A pipeline, and $25M buybacks add tailwinds. 2026 upside hinges on industrial turnarounds, but muted market reaction underscores execution risks.
PFAS growth remains timing-lumpy with EPA thresholds pending, incinerator utilization lagged expectations due to weather/downtime, and industrial services weakness (high refiner runs deferring maintenance) could persist into 2027 or beyond if no rebound materializes.
"CLH's 9% EBITDA growth is real but heavily dependent on PFAS scaling and incinerator utilization reaching 85-90% by mid-year—both have execution risk and regulatory/timing uncertainty that the article downplays."
CLH raised FY EBITDA growth from 5% to 9% on Q1 beat, driven by PFAS momentum (25-35% growth expected), strong environmental services (+6.5%), and base oil tailwinds. The 80% incinerator utilization is underwhelming despite new Kimball capacity, and management admits timing on captive incinerator closures and industrial services recovery is unpredictable. PFAS margin accretion to 30%+ is credible but depends on execution at scale. The stock's 'disappointing' reaction suggests the market is pricing in either execution risk or that 9% EBITDA growth is already baked in at current valuation.
PFAS is a regulatory-dependent, project-driven revenue stream with lumpy timing and no guarantee of the 25-35% growth rate; if EPA granular thresholds don't materialize or military work delays, the entire bull case compresses. Incinerator utilization below 80% in Q1 despite new capacity suggests demand softness that a 'weather and downtime' excuse may be masking.
"CLH’s 2026 upside hinges on a multi-year PFAS cycle and a rebound in industrial services that are not assured, making the near-term upside conditional and potentially fragile."
Clean Harbors (CLH) benefits from a stronger 2026 guide (EBITDA up ~9% vs 5%), and PFAS is positioned as a long-term growth driver with 25–35% revenue growth this year and potential margin lift toward 30%+ in environmental services. Yet the bullish case hinges on several moving parts: PFAS regulation must translate into scalable, margin-accretive work; incineration utilization must sustain near-90% levels; industrial services recovery remains uncertain; base oil and M&A tailwinds could fade. The market reaction being tepid suggests skeptics doubt the duration or magnitude of these catalysts, especially given project-based landfill volumes and weather/downtime risks.
The strongest counterpoint is that PFAS-related revenue is front-loaded into optimism with uncertain regulatory granularity and potential margin compression from higher operating costs; the industrial services rebound is not guaranteed, so the 9% EBITDA lift could prove transitory.
"The failure to hit high-80s incineration utilization despite new capacity signals structural demand softness that will compress margins."
Claude is right to question the 'weather and downtime' excuse. If we look at the 80% incineration utilization, it’s not just a seasonal hiccup; it’s a failure to leverage the high-margin Kimball capacity effectively. While others focus on PFAS growth, they ignore that CLH’s capital intensity is rising. If they can't push utilization toward 90% despite the HEPACO integration, the 30% EBITDA margin target becomes a fantasy, regardless of how much PFAS revenue they book.
"Incineration ramp is progressing as guided; leverage from buybacks and M&A is the unmentioned risk."
Gemini fixates on incineration utilization as a 'failure,' but Grok notes Kimball is still ramping—80% Q1 amid integration is credible progress to mid-80s FY for 27% ES margins. Nobody flags the balance sheet: $25M buybacks plus 'super strong' M&A pipeline amid rising capex could strain net debt/EBITDA (already ~3x), risking credit downgrades if industrial weakness lingers into 2026.
"Balance sheet leverage at 3x net debt/EBITDA during industrial softness makes the M&A and buyback strategy a tail risk, not a tailwind."
Grok flags the real issue Gemini missed: balance sheet strain. Net debt/EBITDA at ~3x while funding $25M buybacks and a 'super strong' M&A pipeline during industrial weakness is aggressive. If capex stays elevated to support Kimball ramp and PFAS scaling, and if industrial services don't recover as hoped, CLH could face covenant pressure or forced deleveraging—which would kill the buyback and M&A thesis entirely. That's the execution risk nobody quantified.
"PFAS revenue growth is regulatory-driven and potentially front-loaded; a delay in EPA thresholds or higher capex could erode margin and covenant safety even with improving incineration utilization."
Overlooked risk: PFAS growth is not guaranteed to scale cleanly into sustainable EBITDA at 30% ES margins. The 25–35% revenue growth is heavily regulatory-driven and potentially front-loaded; a delay in EPA thresholds or a pullback in government contracts could compress margins and temper pricing power. And while incinerator utilization at 80% is improving, it remains the linchpin; if the Kimball ramp stalls or capex accelerates to fund it, the promised margin uplift and FCF generation could disappoint, tightening covenants.
