Management Comments

• "Our record second-quarter results demonstrate the substantial momentum we achieved in both of our operating segments."
• "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."
• "Our team continues to achieve commendable industry-leading safety results with the Company's year-to-date Total Recordable Incident Rate at 0.46."
• "We believe this multi-year contract demonstrates our unique capabilities and versatility to safely process large volumes of variable waste streams."
• "ES&H is a recognized leader in the Gulf region, and its addition is expected to expand our Field Services business."
• "We currently continue to see positive demand trends across both operating segments."
• "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."

Industry Context

StockSavvy.ai notes that Clean Harbors' strong performance aligns with broader trends in environmental services, including increased demand for hazardous waste disposal, remediation of emerging contaminants like PFAS, and the benefits of reshoring manufacturing in North America. The acquisition of ES&H also reflects industry consolidation and strategic expansion to capture market share in key regions.

Comparison to Industry Standards

• The company's Adjusted EBITDA margin of 23.6% in Q2 2026 is a positive indicator, especially given the 190 basis point year-over-year expansion. Benchmarking this against competitors like Waste Management (WM) or Republic Services (RSG) would provide further context on operational efficiency and pricing power within the waste management sector.
• The 17th consecutive quarter of year-over-year Adjusted EBITDA margin expansion in the Environmental Services segment suggests a sustained competitive advantage and effective management of costs and pricing, outperforming many peers who may experience more cyclical margin performance.
• The significant growth in the Safety-Kleen Sustainability Solutions segment (41% revenue increase, 143% Adjusted EBITDA increase) highlights a strong performance in the used oil re-refining market, which has seen favorable pricing dynamics due to global supply disruptions. This segment's performance is particularly noteworthy compared to broader industrial commodity markets.
• The acquisition of ES&H at an expected post-synergy multiple of 8.7 times Adjusted EBITDA is a common valuation metric in the environmental services M&A landscape. This multiple should be compared to recent transactions involving similar-sized regional players in the environmental and emergency response sectors.

Legal Proceedings

• Risks associated with existing and potential litigation are mentioned as a factor that could cause actual results to differ materially from forward-looking statements.

Stakeholder Impact

• Shareholders: Expected to benefit from record financial results, increased profitability, and raised full-year guidance, potentially leading to stock price appreciation.
• Employees: Continued strong performance and growth may lead to job security and potential for bonuses or raises. The acquisition of ES&H will integrate new employees into the company.
• Customers: Benefit from expanded service offerings and continued reliable environmental and industrial services. The new disposal contract indicates a strong, long-term relationship with a major customer.
• Suppliers: Increased operational activity and growth may lead to increased demand for raw materials and services from suppliers.

Next Steps

• Complete the acquisition of ES&H in the second half of 2026.
• Commence the ten-year disposal contract in the fourth quarter of 2026.
• Reach full capacity on the new disposal contract by 2030.
• Continue to pursue new contract opportunities and expand relationships with growing manufacturing customers.
• Pursue opportunities for new contracts and expand relationships with existing customers who are growing their North American manufacturing presence.
• Introduce a new strategic offering for data centers.
