NORWELL, Mass. - October 29, 2025 - Clean Harbors, Inc. (“Clean Harbors” or the “Company”) (NYSE: CLH), the leading provider of environmental and industrial services throughout North America, today announced financial results for the third quarter ended September 30, 2025.
“Our third-quarter performance reflected continued growth in our Technical Services and Safety-Kleen Environmental Services revenues,” said Eric Gerstenberg, Co-Chief Executive Officer. “We increased our consolidated Adjusted EBITDA margin by 100 basis points from a year ago by continuing to manage costs, driving operating efficiencies and increasing waste volumes handled through our disposal and recycling network. Within safety, our team did an excellent job protecting themselves and each other; at quarter end our year-to-date Total Recordable Incident Rate (TRIR) was just 0.49, putting us on track for a record year.”
Third-Quarter 2025 Results
Revenues were $1.55 billion, compared with $1.53 billion in the same period of 2024. Income from operations was $193.0 million, compared with $192.3 million in the third quarter of 2024.
Net income was $118.8 million, or $2.21 per diluted share, compared with $115.2 million, or $2.12 per diluted share, for the same period in 2024.
Adjusted EBITDA (see description and reconciliation below) increased 6% to $320.2 million from $301.8 million for the same period in 2024.
Q3 2025 Segment Review
“By leveraging our network, focusing on labor management and continuing our pricing strategies, our ES segment achieved its 14th consecutive quarter of year-over-year improvement in Adjusted EBITDA margin, which increased by 120 basis points to 26.8%,” said Gerstenberg. “The segment’s 3% top-line growth was led
Clean Harbors • 42 Longwater Drive • PO Box 9149 • Norwell, Massachusetts 02061-9149 • 800.282.0058 • www.cleanharbors.com by Technical Services, which grew 12% despite slowdowns with customers in some key verticals such as the chemical space due to general economic conditions and tariff driven uncertainty. Offsetting these slowdowns was significant growth from other verticals, increased remediation and waste project work, and demand for our Total PFAS Solution. Safety-Kleen Environmental Services revenue rose 8% through a combination of price and steady volume growth. High demand for disposal led to incineration utilization, excluding the new Kimball incinerator, of 92%, while landfill volumes were up 40% on project strength. Field Services revenue declined from prior year due to the absence of medium- to large-scale emergency response projects in the quarter. Within Industrial Services, chemical and refining customers continued to limit their turnaround spending. The softness in these end markets, combined with the lack of large emergency response projects and increased healthcare costs, resulted in lower-than-anticipated results for the Environmental Services segment. However, the team remains focused on margin growth and cash flow generation, and we believe that initiatives in those areas puts us in a position to greatly benefit as economic conditions improve.”
“Our Safety-Kleen Sustainability Solutions (SKSS) segment results in the quarter were consistent with our expectations. We dramatically lowered waste oil collection costs and improved our mix of products sold in the face of weaker base oil pricing,” said Mike Battles, Co-Chief Executive Officer. “We gathered 64 million gallons of waste oil, which kept our plants at full production. We incrementally increased our direct lubricant gallons sold to 9% of total volume, which helped drive our margin improvement in the segment. As highlighted in our recent news release, we are advancing our strategic shift toward higher charge-for-oil (CFO) pricing for our collection services to proactively address base oil market conditions.”
Investing in SDA Unit to Unlock Value of Re-refining Byproducts
Clean Harbors today announced plans to build a state-of-the-art processing plant that employs innovative solvent de-asphalting (SDA) technology to convert a re-refining byproduct - vacuum tower asphalt extender (VTAE) - into a high-value 600N base oil. Total investment in this facility is expected to be $210 million to $220 million with commercial launch anticipated in 2028.
“By using an industry-proven SDA process, combined with our existing hydrotreating capabilities, we expect to unlock incremental value from an everyday byproduct generated today at our re-refineries,” Battles said. “For several years we have been evaluating ways to upgrade VTAE, which we currently sell to roofing and paving markets, into a more valuable and profitable product. Because of its durability and high-performance characteristics, 600N is a high-purity base oil typically used in heavy-duty industrial applications. We expect this facility to generate annual EBITDA of $30 million to $40 million, a six- to seven-year payback on the investment once completed, which rivals the returns on our incineration projects.”
Business Outlook and Financial Guidance
“Looking ahead, we believe that the market challenges we faced in the third quarter are temporary and brought on by macro-economic conditions. The continued growth in Technical Services and Safety-Kleen Environmental demonstrates the diversification of our end markets and continued resilience of our business model. We expect our incinerators to continue to run strong through year-end and projects to continue to feed
Clean Harbors • 42 Longwater Drive • PO Box 9149 • Norwell, Massachusetts 02061-9149 • 800.282.0058 • www.cleanharbors.com our entire disposal and recycling network,” Gerstenberg said. “The North American economy has been navigating through short-term turbulence, but the economic outlook looks promising as reshoring continues. Based on conversations with our customers, we anticipate incentives to reshore and the benefits of the recent U.S. tax bill will drive a meaningful lift in American manufacturing, as well as continue to support remediation and waste projects. Spending constraints related to key verticals, such as chemicals and refining, should loosen in the coming quarters as economic conditions improve, benefiting our Industrial Services and Field Services businesses. Labor efficiencies and other margin generating initiatives we have undertaken put us in a good position to benefit when those key verticals rebound. Overall, we continue to see a substantial project pipeline that is only strengthened by growing PFAS opportunities. We believe our initiatives around CFO, partnerships and Group III production have stabilized our SKSS business. As a result, we expect to achieve our profitability target for this business in 2025.”
Battles concluded, “Given our current market outlook, we expect to conclude 2025 with a strong fourth-quarter performance that includes Adjusted EBITDA growth in the six to eight percent range compared with a year ago. We remain on track to deliver a record level of annual Adjusted EBITDA and adjusted free cash flow in 2025 with a healthy long-term market outlook.”
For full-year 2025, Clean Harbors is revising its prior guidance and now expects:
- Adjusted EBITDA in the range of $1.155 billion to $1.175 billion, or a midpoint of $1.165 billion, which represents 4% growth year over year. This Adjusted EBITDA range is based on anticipated GAAP net income in the range of $379 million to $400 million.
- Adjusted free cash flow in the range of $455 million to $495 million, or a midpoint of $475 million, which represents more than a 30% increase from prior year. This range is based on anticipated net cash from operating activities in the range of $795 million to $865 million.
Non-GAAP Results
Clean Harbors reports Adjusted EBITDA, which is a non-GAAP financial measure and should not be considered an alternative to net income or other measurements under generally accepted accounting principles (GAAP) but viewed only as a supplement to those measurements. Adjusted EBITDA is not calculated identically by all companies, and therefore the Company’s measurement of Adjusted EBITDA may not be comparable to similarly titled measures reported by other companies. Clean Harbors believes that Adjusted EBITDA provides additional useful information to investors because the Company’s management routinely evaluates the performance of its businesses based upon levels of Adjusted EBITDA. The Company defines

Adjusted Free Cash Flow Reconciliation
Clean Harbors reports adjusted free cash flow, a non-GAAP measure, which it considers to be a measurement of liquidity that provides useful information to investors about its ability to generate cash. The Company defines adjusted free cash flow as net cash from operating activities less additions to property, plant and equipment plus proceeds from sale and disposal of fixed assets. When necessary, the Company adjusts for the cash impact of items derived from non-operating activities. Adjusted free cash flow should not be considered an alternative to net cash from operating activities or other measurements under GAAP. Adjusted free cash flow is not calculated identically by all companies, and therefore the Company’s measurement of adjusted free cash flow may not be comparable to similarly titled measures reported by other companies.
An itemized reconciliation between reported GAAP net cash from operating activities and adjusted free cash flow is as follows (in thousands):
