Future Outlook

The company expects interest expense, net of interest income, to remain relatively consistent with the prior year for the remainder of 2025, including the impact of recent refinancing transactions. Total capital spending for 2025, net of disposals, is anticipated to be in the range of $385.0 million to $415.0 million, which includes approximately $30 million for a solvent de-asphalting unit (SDA) and $15 million for a Phoenix Hub facility.

The company believes its future operating cash flows will be sufficient to meet its future operating and internal investing cash needs and expects to fund remaining 2025 capital spending and future SDA spending from operations. Management also believes the company will continue to meet the covenants of all its debt agreements. The Management Incentive Plan (MIP) has been amended and restated, effective January 1, 2026.

Management Comments

• We are North America's leading provider of environmental and industrial services, supporting our customers in finding environmentally responsible solutions to further their sustainability goals.
• We believe we operate, in the aggregate, the largest number of hazardous waste incinerators, landfills and treatment, storage and disposal facilities (TSDFs) in North America.
• Management tracks the volumes and mix of waste handled and disposed of or recycled, generally through our incinerators, TSDFs and landfills, the utilization rates of our incinerators, equipment and workforce, including billable hours and the number of parts washer services performed, and pricing realized by our business and peer companies as well as other key metrics.
• Management of operating costs is vital to our ability to remain price competitive.
• We continue to experience inflationary pressures across several cost categories, but most notably related to internal and external labor, healthcare, transportation, maintenance and energy related costs.
• We aim to manage these increases through constant cost monitoring and a focus on cost savings areas, including lowering employee turnover, as well as our overall customer pricing strategies designed to offset the inflationary impacts on our margins.
• Our ability to properly align these costs with business performance is reflective of our strong management of the businesses and further promotes our ability to remain competitive in the marketplace.
• Adjusted EBITDA is considered a measurement of performance that provides useful information to both management and investors.
• We assess our liquidity in terms of our ability to generate cash to fund our operating, investing, and financing activities.
• We believe our future operating cash flows will be sufficient to meet our future operating and internal investing cash needs.
• We continue to monitor our debt instruments and evaluate opportunities where it may be beneficial to refinance or reallocate the portfolio.
• As of September 30, 2025, we were in compliance with the covenants of all of our debt agreements, and we believe we will continue to meet such covenants.
• In management's opinion, it is not reasonably possible that the potential liability beyond what has been recorded, if any, that may result from these actions, either individually or collectively, will have a material effect on the company's financial position, results of operations or cash flows.

Industry Context

Clean Harbors operates as North America's leading provider of environmental and industrial services, holding a dominant position with the largest number of hazardous waste incinerators, landfills, and treatment, storage, and disposal facilities (TSDFs). The company's performance is significantly influenced by broader macroeconomic factors such as North American GDP, U.S. industrial production, and economic conditions within the general manufacturing, chemical, and automotive markets. Demand for its services is also shaped by the regulatory environment, including evolving regulations related to perand polyfluoroalkyl substances (PFAS), available waste disposal capacity, and the need for industrial cleaning and emergency response services. The Safety-Kleen Sustainability Solutions (SKSS) segment's results are particularly sensitive to market pricing and demand for recycled oil products, as well as global commodity oil price volatility. The company's strategic acquisitions, such as HEPACO and Noble, aim to expand its service offerings and market reach within this dynamic industry.

Corporate Governance

Legal Proceedings

The company maintains insurance coverage for these claims.
• The company has been identified as a potentially responsible party (PRP) or potential PRP for indemnification obligations at 132 Superfund-related sites (6 owned/leased facilities and 126 third-party sites).
• Of the 126 third-party Superfund sites, 30 are settled, 12 are currently requiring expenditures on remediation, and 84 are not currently requiring expenditures.
• The company believes its potential monetary liability could exceed $1.0 million at three of the 132 Superfund-related sites.
• Indemnification agreements are in place at 17 Superfund sites, covering liabilities for waste disposed prior to certain acquisitions, with indemnifying parties paying defense and settlement costs.

Stakeholder Impact

• Shareholders: Benefit from increased Q3 net income and Adjusted EBITDA, strong cash flow generation, and an active common stock repurchase program ($116.8 million YTD, $382.4 million remaining authorization). The debt refinancing improves the company's financial structure and reduces interest rate risk.
• Employees: Impacted by 'strategic headcount management actions' in the SKSS segment, which contributed to labor cost reductions. The amended Management Incentive Plan (MIP) provides a structured framework for annual cash bonuses tied to company and individual performance.
• Customers: Benefit from the company's expanded service offerings through acquisitions (e.g., HEPACO) and continued investment in facilities (e.g., Kimball incinerator, SDA project), enhancing capacity and service quality. Pricing strategies are designed to offset inflationary impacts while maintaining competitiveness.
• Creditors: The recent debt refinancing extends maturities and reduces interest rates on certain term loans, improving the company's credit profile and demonstrating strong financial management. The company remains in compliance with all debt covenants.

• Redeem $545.0 million of 4.875% senior notes due 2027 on October 31, 2025.
• Continue construction of a solvent de-asphalting unit (SDA) with expected completion in 2028.
• Continue the build-out of a hub facility in Phoenix, Arizona.

Key Dates

Recommendation

Clean Harbors demonstrated robust Q3 performance with increased revenues, net income, and Adjusted EBITDA, indicating strong operational execution in its core Environmental Services segment. The significant improvement in adjusted free cash flow and net cash from operating activities highlights strong liquidity and cash generation capabilities. The successful debt refinancing initiative, which extends maturities and reduces interest costs, strengthens the company's financial position and reduces future interest rate risk. Furthermore, the ongoing share repurchase program signals management's confidence in the company's valuation and commitment to returning capital to shareholders. While the SKSS segment faced some pricing challenges, the overall strategic direction, cost management efforts, and long-term growth investments (SDA, Phoenix Hub) position Clean Harbors for continued value creation.
