CLEAN HARBORS INC Q3 FY2026 earnings call

• Executive Transition: Co-CEO Mike Battles is retiring at year-end, and Eric Gerstenberg will become sole CEO on January 1st, 2027, ending a successful co-leadership tenure.
• Safety Performance: Delivered industry-leading safety metrics with a Year-to-Date Total Recordable Incident Rate (TRIR) of 0.49, matching the best full-year rate in company history.
• Emergency Response Momentum: A significant warehouse fire in Los Angeles generated ~$120 million in Q3 revenue, demonstrating operational capability and bolstering the pipeline for future large-scale events.
• Reshoring and Consolidation Trends: Continued strength in U.S. manufacturing reshoring is driving demand. The company is successfully positioning itself as a single-service provider for customers consolidating waste management needs, evidenced by a new 10-year, $600 million contract commencing in Q4.
• Data Center Growth: Initial engagements are gaining traction. Management is accelerating capital investment in data center services, increasing the dedicated capital target from $50 million to $70 million over two years, expecting superior returns above the cost of capital.
• PFAS Pipeline: Strong ongoing demand for PFAS-related work across water filtration, remediation, and AFFF changeouts, with revenue expected to grow 30% year-over-year, surpassing $150-$200 million annually.
• Capital Allocation Discipline: Successful integration of ES&H and EnviroServe acquisitions. Moving forward with a $55 million Los Angeles hub consolidation to improve efficiency and growth capacity. Maintaining a strong balance sheet with low leverage following a $600 million note offering.

Environmental Solutions (ES): Revenue increased by $220 million year-over-year, driven primarily by a 70%+ surge in field services due to a major emergency response event generating approximately $120 million. Safety Clean Environmental Services revenue grew 11%, and Technical Services rose 3%. Adjusted EBITDA increased 19% with margins expanding 60 basis points to 27.4%. This segment contributed significantly to the company's total revenue growth.

Skunk Specialties & Solvents (SKSS): Revenue surged 46% year-over-year, and Adjusted EBITDA more than tripled to $126 million, reaching a record high for the quarter. This performance was driven by tight global supply of base oil and lubricants, effective spread management, and a 20% increase in higher-margin Group 3 production. SKSS remains a key contributor to margin expansion despite typical Q4 seasonality.

• 2026 Adjusted EBITDA Guidance Raised: Increased to a range of $1.44 billion to $1.48 billion (midpoint $1.46 billion), an $80 million increase from the previous midpoint. This implies ~25% growth over FY 2025.
• 2026 Adjusted Free Cash Flow Raised: Increased to a range of $600 million to $660 million (midpoint $630 million), up $80 million from prior outlook.
• 2026 Segment Breakdown:
  • ES Segment: Expects mid-to-high single-digit EBITDA growth (9-11% midpoint), including ~$10 million contribution from recent acquisitions.
  • SKSS Segment: Assumes ~$340 million in adjusted EBITDA; management maintains a conservative outlook due to uncertainty around how long elevated base oil prices will persist.
  • Corporate: Expects adjusted EBITDA expense to increase 14-17% from 2025 levels, driven by incentive compensation, acquisition impacts, and strategic initiative costs.
• 2026 Full-Year CapEx: Expected to be between $490 million and $500 million for Depreciation & Amortization. Net CapEx excluding strategic initiatives is guided at $370-$430 million (midpoint $400 million).
• Q4 2026 Expectations: Anticipates healthy year-over-year growth in both segments, with consolidated Q4 Adjusted EBITDA expected to grow 23-26% YoY (excluding large ER events which occurred in Q4 2025).
• 2027 Guidance: Will be provided during the Q4 2026 earnings call in February 2027.

• Market Volatility in SKSS: Uncertainty regarding how long current elevated base oil and lubricant prices will remain high due to global refining disruptions. Management notes that while current conditions are favorable, pricing normalization poses a long-term risk to spreads.
• Acquisition Integration Risks: Early-stage headwinds from recent acquisitions (ES&H, EnviroServe) have impacted margins slightly (estimated 20 bps drag in Q3). Full synergy realization takes time.
• Large-Scale Event Dependency: Q3 results were significantly boosted by a one-time $120 million emergency response event. Future quarters may face comp challenges if similar large events do not recur.
• Industrial Services Slowdown: North American refinery turnaround activity remains soft, limiting growth in core industrial services, although data centers and specialty work provide offsetting opportunities.
• Regulatory and Operational Complexity: Managing complex waste streams from reshored manufacturing and PFAS remediation requires continuous adaptation of technology and compliance strategies.

Q: Analyst asked about the ROI and scalability of the 'Hub Strategy' exemplified by the new LA facility, referencing past successes in Baltimore and Phoenix. / A: Eric Gerstenberg explained that hubs consolidate multiple business units into one location to enable cross-selling, shared resources, and career development without relocation. The LA hub consolidates six legacy branches and five business units into a larger scale operation, addressing regulatory constraints and fueling significant growth in a tough market. He noted this is likely the largest hub they will ever build, with other potential hubs being much smaller.

Q: Analyst inquired if the underlying growth algorithm for the ES segment remains intact for next year given the Q3 emergency response boost and difficult comps. / A: CFO Eric Dugas confirmed that the ES segment is historically a mid-single-digit grower, with upside from large emergency responses. He stated that while Q3 delivered ~10% growth (vs. 5-6% guidance), the underlying organic trend supports mid-single-digit growth minimums. He emphasized that the sales pipeline, deferred revenue growth, and emerging opportunities like PFAS and data centers support continued momentum into 2027.

Q: Analyst asked if reshoring incentivizes captive incinerators to stay open or pressures them to close, impacting Clean Harbors' opportunity set. / A: Eric Gerstenberg clarified that reshoring does NOT keep captive incinerators open; rather, it changes waste streams produced by chemical companies, lowering utilization of existing captives. This creates a catalyst for Clean Harbors to offer broader services for unique waste streams captives cannot handle. Management expects 1-2 additional captive incinerators to go offline in the next few years, representing upside to their model.

Q: Analyst requested details on the nature of the large emergency response event and its impact on the updated 2026 EBITDA guidance puts/takes. / A: Eric Gerstenberg described the event as a massive warehouse fire in LA involving 75,000 tons of deteriorating frozen food waste, cleaned up within Q3 and generating $120 million in revenue. CFO Eric Dugas broke down the $80 million guidance raise: ~$30 million beat in Q3 (half from the ER job), plus $10 million from acquisitions. He noted that while the ER job was largely in Q3, some acceleration may shift minor amounts, but the overall guidance reflects strong underlying volumes and execution.

Q: Analyst asked about the cadence and revenue recognition of the announced 10-year, $600 million reshoring contract, specifically if revenue flows during construction or ramp-up. / A: CFO Eric Dugas confirmed the contract kicked in Q4 with approximately $10 million in revenue from initial loads, ahead of schedule. He expects revenue to ramp to $25-$35 million annually as the customer’s facilities come online. Eric Gerstenberg added that embedding systems and personnel early has led to additional service opportunities, validating the strategy of becoming a total waste management provider for reshored manufacturers.
