NORWELL, Mass. – July 29, 2026 – 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 second quarter ended June 30, 2026.

“Our record second-quarter results demonstrate the substantial momentum we achieved in both of our operating segments,” said Mike Battles, Co-Chief Executive Officer. “Our Environmental Services (ES) segment benefited from a combination of healthy volumes into our disposal and recycling network, remediation projects, PFAS-related work and our strategic pricing initiatives to offset inflation and fuel costs. Within our Safety-Kleen Sustainability Solutions (SKSS) segment, a sharp uptick in market pricing for our re-refined products drove significant profitability during the quarter. In addition, our team continues to achieve commendable industry-leading safety results with the Company’s year-to-date Total Recordable Incident Rate at 0.46.”

Second-Quarter 2026 Results

Revenues increased 12% to $1.74 billion, compared with $1.55 billion in the same period of 2025. Income from operations rose 28% to $268.9 million, compared with $210.3 million in the second quarter of 2025.

Net income increased 34% to $170.5 million, or $3.22 per diluted share, compared with $126.9 million, or $2.36 per diluted share, for the same period in 2025.

Adjusted EBITDA (see description and reconciliation below) increased 22% to $409.0 million from $336.2 million for the same period in 2025.

Second-Quarter 2026 Segment Review

“Our ES segment delivered its 17th consecutive quarter of year-over-year Adjusted EBITDA margin expansion with a margin of 27.9%,” said Eric Gerstenberg, Co-Chief Executive Officer. “Within the segment, Technical Services grew revenue 18% on strong demand for disposal and recycling services. We continued to win base business and sizeable projects, including a large PFAS-related filtration project that resulted from previous emergency response work. Safety-Kleen Environmental Services’ revenue in the segment increased 11%, driven by pricing and growth in its core offerings, including containerized waste collection and vacuum services. Incineration utilization, including the new Kimball incinerator, was 91% compared with 86% a year ago. At the same time, landfill volumes rose 7% in the quarter. Field Services revenue grew 3% year-over-year, despite a difficult comp with large emergency response (ER) projects in the prior period. Overall, it was an exceptional quarter for this segment, reflecting our ability to capture strong, sustained demand trends that we expect to remain intact as we move into the second half of the year.”

“SKSS segment revenue increased 41% in Q2 and Adjusted EBITDA was 143% higher, with segment margin up more than 70% from the year ago period,” Battles said. “This performance reflects market conditions resulting from major global supply disruptions of refined products. We also saw the benefit of ongoing strategic initiatives including producing Group III gallons and selling more blended volume. Our collections team also did a remarkable job actively managing the front end of our re-refining spread, balancing both collection volumes and costs. We gathered 61 million gallons of waste oil while continuing to increase revenues generated from our used oil collection services compared with a year ago. The SKSS segment executed well in the quarter and these supply conditions are expected to extend into the third quarter.”

Awarded Ten-Year Disposal Contract

Clean Harbors also announced today that it recently won a significant, ten-year disposal contract with a customer that is expanding its U.S. manufacturing operations. The contract, which involves incineration waste and complex wastewater volumes, carries an estimated value of $600 million over the life of the contract with options to expand in scope. The contract will commence in the fourth quarter of this year and is expected to reach full capacity in 2030, based on the ramp-up of multiple manufacturing sites by the customer.

“We believe this multi-year contract demonstrates our unique capabilities and versatility to safely process large volumes of variable waste streams,” Gerstenberg said. “This customer selected Clean Harbors as a long-term partner because of the vast capabilities, scale and redundancy of our disposal network. This contract also reflects current U.S. expansion trends due to reshoring. Given the widespread capabilities of our assets, we expect to pursue opportunities for new contracts and to expand our relationships with existing customers who are growing their North American manufacturing presence.”

Agreement to Acquire ES&H to Bolster Field Services

Clean Harbors also has entered into a definitive agreement to acquire ES&H, a leading regional provider of environmental and ER services in the Gulf region for $305 million in cash. The acquisition is expected to close in the second half of 2026, subject to regulatory approval and other customary closing conditions.

“ES&H is a recognized leader in the Gulf region, and its addition is expected to expand our Field Services business,” Battles said. “We expect to derive attractive shareholder returns from this transaction as ES&H has built a well-established brand over its 30-year history. The company has a strong reputation as a great resource for on-water response, and like Clean Harbors, carries the Coast Guard’s highest Oil Spill Response Organization (OSRO) classification. Their talented employees, geographic footprint and equipment fleet will enhance our existing Field Services business.”

Headquartered in Louisiana, ES&H has 13 service branches, the majority of which are coastal locations that support its maritime services, which complement Clean Harbors’ existing offerings. The company’s primary offerings include emergency response, field services and environmental impact management services for customers across multiple industries. ES&H’s annual base revenues are approximately $90 million, generating annual Adjusted EBITDA of approximately $30 million. Clean Harbors expects the acquisition to generate cost synergies of approximately $5 million after the first full year of operations, which equates to a post-synergy acquisition multiple of 8.7 times.

Business Outlook

“We currently continue to see positive demand trends across both operating segments,” Gerstenberg said. “The U.S. Manufacturing PMI was above 50 – indicating nationwide expansion – for the first six months of 2026. Our recent discussions with customers suggest a strengthening U.S. economy will support greater volumes into our network and drive demand for our various services. We believe that ongoing reshoring is creating opportunities for us to add new customer locations and waste streams. Our PFAS pipeline continues its growth in the U.S. and Canada, including both private and government customers. Our Field Services business is currently working on multiple large emergency response events that should support Q3 growth in that business and further enhance our reputation as a national go-to provider for environmental emergencies. Within Industrial Services, we are introducing a new strategic offering for data centers that we expect will generate growth in that business in the years ahead. For SKSS, the business continues to be well-managed at both ends of our spread while operating in a favorable demand environment. Overall, we expect to realize strong operating results in both segments in the second half on our way to delivering record results for the full year.”

Financial Guidance

In the third quarter of 2026, Clean Harbors expects Adjusted EBITDA to grow 24% to 28% year over year. Based on its first-half performance and current market conditions, Clean Harbors is raising the midpoint of its

Clean Harbors • 42 Longwater Drive • PO Box 9149 • Norwell, Massachusetts 02061-9149 • 800.282.0058 • www.cleanharbors.com

2026 Adjusted EBITDA guidance by $110 million and the midpoint of its adjusted free cash flow guidance by $30 million. For the full year, Clean Harbors now expects:

•Adjusted EBITDA in the range of $1.35 billion to $1.41 billion, with a midpoint of $1.38 billion. This Adjusted EBITDA range is based on anticipated GAAP net income in the range of $481 million to $531 million.

•Adjusted free cash flow in the range of $520 million to $580 million, with a midpoint of $550 million. This range is based on anticipated net cash from operating activities in the range of $890 million to $1,010 million.

Non-GAAP Results:

Adjusted EBITDA Reconciliation

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 EBITDA as described in the following reconciliation showing the differences between reported net income and Adjusted EBITDA for the three and six months ended June 30, 2026 and 2025 (in thousands, except percentages):


	Three Months Ended						Six Months Ended
	June 30, 2026			June 30, 2025			June 30, 2026			June 30, 2025

Adjusted EBITDA Margin	23.6		%	21.7		%	20.6		%	19.2		%

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

Clean Harbors • 42 Longwater Drive • PO Box 9149 • Norwell, Massachusetts 02061-9149 • 800.282.0058 • www.cleanharbors.com

items derived from non-operating activities. Additionally, adjusted free cash flow excludes significant strategic growth investments, as they are not indicative of free cash flow for the current period. 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):
