Clean Harbors: 3 Key Takeaways for Long-Term Investors

On its third-quarter 2026 earnings call, held on Oct. 28, 2026, Clean Harbors (NYSE:CLH) announced record quarterly revenue of $1.87 billion alongside an increased full-year outlook. Industrial reshoring and customer demand for single-source waste management expand the company's addressable market. Growing cash flow gives management flexibility to acquire regional operators and fund high-return infrastructure. Three key takeaways from management's presentation stand out for long-term investors.

1. Reshoring Contracts and Customer Consolidation Fuel Core Growth

The return of industrial manufacturing to North America creates steady demand for specialized waste handling. The Environmental Services (ES) segment, which handles hazardous waste disposal and industrial cleaning, continues to secure long-term commercial agreements as customers consolidate their waste vendors.

The 10-year $600 million reshoring contract we announced last quarter has commenced here in Q4, and we're excited to see that relationship expand in the coming years.
-- Eric Gerstenberg, Co-Chief Executive Officer

2. Strategic Regional Hubs and Data Center Investments Expand Capacity

Management is deploying capital into high-return internal projects, including a $55 million property purchase in Los Angeles to consolidate six legacy facilities into a single West Coast operational hub. The company is also increasing capital expenditures, or cash spent on physical assets, to $15 million this year for dedicated data center infrastructure services.

We expect annual savings in the range of $5 million to $7 million of lease consolidation alone, along with the strong growth potential of the site.
-- Michael Battles, Co-Chief Executive Officer

3. Product Mix Shift Strengthens Safety-Kleen Sustainability Solutions

The Safety-Kleen Sustainability Solutions (SKSS) segment, which rerefines used motor oil into recycled lubricants, delivered record quarterly results amid tight market supply. To protect profitability as market pricing eventually normalizes, management is shifting production toward premium offerings such as Group III base oil, a highly refined synthetic lubricant.

Production of Group III increased approximately 20% from a year ago and Group III carries a much higher level of profitability.
-- Michael Battles, Co-Chief Executive Officer

Looking Ahead

Revenue momentum across Environmental Services and oil rerefining is expanding operating leverage while customer backlogs continue to accumulate. The company maintains durable competitive advantages through its scarce permitted incinerators, vast transportation network, and growing regional hub footprint. Management is monitoring industrial production trends, pricing discipline, and integration timelines for recent acquisitions.

We exit Q3 with a healthy outlook and are well positioned to capitalize on these market dynamics through the disciplined capital allocation strategy Mike outlined.
-- Eric Dugas, Executive Vice President and Chief Financial Officer

Long-term value creation depends on sustaining high utilization across waste disposal assets and executing targeted organic investments. With low net debt leverage and expanding free cash flow, the company has significant financial flexibility to compound returns.

Overall, we see a clear path to delivering our record results in 2026 with a number of tailwinds we expect to carry into 2027 and beyond.
