Eric Gerstenberg, Co-Chief Executive Officer of Clean Harbors, discussed the company's financial and operational performance during the third quarter 2025 earnings call on October 29, 2025. He stated that the company's consolidated adjusted EBITDA margin increased by 100 basis points year-over-year to 20.7%, which he attributed to pricing, network leverage, and cost-saving strategies. Gerstenberg noted that the Environmental Services segment's adjusted EBITDA margin grew year-over-year for the 14th consecutive quarter, with revenue up 3% and adjusted EBITDA up 7%. He also mentioned that incineration utilization remained high and landfill volumes were up 40% from a year ago. Regarding the Safety-Kleen Sustainability Solutions (SKSS) business, Gerstenberg expressed confidence in achieving a $140 million adjusted EBITDA target for the year, citing pricing initiatives and market conditions. Gerstenberg addressed the company's work with per- and polyfluoroalkyl substances (PFAS), stating that a recent incineration study conducted in partnership with the EPA and the Department of Defense confirmed that Clean Harbors' permitted high-temperature incinerators can safely destroy PFAS at a cost-effective commercial scale. He said the company expects PFAS to generate $100 million to $120 million in revenue for the year, up 20% to 25% from a year ago. On healthcare costs, Gerstenberg said the frequency of high-cost claims in 2025 appeared higher than normal but that he did not necessarily see that impact continuing, adding that the company was taking internal steps to mitigate future increases. He also noted that the company achieved its lowest-ever quarterly total recordable incident rate (TRIR) of 0.40 in the second quarter of 2025.
