Why The Stock Moved

Qualitative Assessment

AI Analysis | Feedback

Updated on 8/1/2026

Clean Harbors (CLH) stock has remained largely at the same level since 4/30/2026 because of the following key factors:

1. Mixed fiscal Q1 2026 results led to an initial stock decline.

Clean Harbors announced its fiscal Q1 2026 results on May 6, 2026, reporting diluted earnings per share (EPS) of $1.19, which surpassed the analyst consensus of $1.15. However, revenue came in at $1.46 billion, slightly missing the forecast of $1.47 billion. Despite achieving the highest Q1 revenue in the company's history, the stock fell 8.62% to close at $286.65 on May 6, 2026, primarily due to modest revenue growth and broader market concerns.

2. Record fiscal Q2 2026 performance and raised full-year guidance fueled a recovery.

The stock rebounded following the announcement of record fiscal Q2 2026 results on July 29, 2026, which saw EPS of $3.22, significantly beating the consensus estimate of $2.81. Quarterly revenue rose 11.9% year-over-year to $1.74 billion, exceeding analysts' expectations of $1.64 billion. Clean Harbors also raised its full-year 2026 adjusted EBITDA guidance to a midpoint of $1.38 billion (up $110 million from prior guidance) and its adjusted free cash flow guidance to a midpoint of $550 million (up $30 million). This strong operational and financial performance, coupled with an increased outlook, led the stock to trade up, reaching $326.34 on July 29, 2026, near its 52-week high.

This strong operational and financial performance, coupled with an increased outlook, led the stock to trade up, reaching $326.34 on July 29, 2026, near its 52-week high.

3. Strategic growth initiatives provided long-term revenue visibility.

Clean Harbors announced several strategic moves alongside its Q2 2026 results, contributing to investor confidence. These included a definitive agreement to acquire ES&H for $305 million in cash, which is expected to expand its Field Services business in the Gulf region and add approximately $90 million in annual base revenue and $30 million in annual Adjusted EBITDA. Additionally, the company secured a significant 10-year disposal contract with an estimated value of $600 million for incineration waste and complex wastewater services, set to begin in fiscal Q4 2026. The company is also expanding into the data center services market, with plans to invest $50 million over the next three years to achieve $200 million in annual revenue by 2028.

4. Favorable industry dynamics and increased demand for specialized services supported stability.

The company benefited from positive demand trends across its Environmental Services (ES) and Safety-Kleen Sustainability Solutions (SKSS) segments. The U.S. Manufacturing PMI remained above 50, indicating nationwide expansion for the first six months of 2026, which supported greater volumes into Clean Harbors' network. The SKSS segment experienced a sharp uptick in market pricing for its re-refined products, driving revenue growth of over 40% year-over-year in Q2 2026. Furthermore, growth in PFAS-related work and remediation projects accelerated to over 30% year-over-year, partly due to the Department of Defense lifting its moratorium on incineration, further bolstering the company's performance.

AI Analysis | Feedback

The key risks to Clean Harbors (CLH) business are primarily centered around stringent environmental regulations, economic cyclicality impacting industrial activity, and the inherent volatility within its Safety-Kleen Sustainability Solutions segment.

  1. Regulatory Risks and Environmental Liabilities: Clean Harbors operates within a highly regulated industry, meaning that increasingly strict environmental laws and regulations pose a significant risk. These regulations, particularly concerning substances such as Per- and Polyfluorofluoroalkyl Substances (PFAS), can lead to higher compliance costs for its operations and facilities, as well as potential environmental liabilities and operational challenges. For example, the company's Safety-Kleen division has faced settlements with the U.S. Environmental Protection Agency (EPA) over environmental compliance issues, highlighting the ongoing risk of non-compliance and associated penalties.
  2. Economic Cyclicality and Industrial Activity: The demand for Clean Harbors' environmental and industrial services, particularly within its Environmental Services segment, is closely tied to the level of industrial activity. Economic downturns or slowdowns in sectors like chemical, refining, or manufacturing can lead to reduced waste volumes and lower demand for the company's high-margin project work, consequently pressuring revenue and unit margins.
  3. Volatility in the Safety-Kleen Sustainability Solutions Segment: The profitability and revenue of the Safety-Kleen Sustainability Solutions (SKSS) segment are highly sensitive to global oil prices and the demand for lubricants. Fluctuations in base oil prices and the overall market for re-refined products can lead to significant margin pressure and has contributed to declining revenues and profits in this segment in recent years.

AI Analysis | Feedback

The increasing adoption of electric vehicles (EVs) poses an emerging threat to Clean Harbors' Safety-Kleen Sustainability Solutions segment, specifically impacting its used motor oil collection services. As the automotive industry shifts away from internal combustion engine (ICE) vehicles, the demand for traditional motor oil changes will significantly decline, thereby reducing the volume of used motor oil available for collection and processing.

AI Analysis | Feedback

AI Analysis | Feedback

Clean Harbors (CLH) is expected to drive future revenue growth over the next 2-3 years through several key initiatives and market trends:
  • Continued Expansion of the Environmental Services Segment: The company anticipates ongoing strong performance in its core Environmental Services segment, specifically citing growth in Technical Services, driven by robust demand for disposal and recycling services, and Field Services, which includes industrial maintenance and emergency response activities. This segment has consistently contributed to the company's overall revenue growth.
  • Growing Demand for PFAS Remediation Services: Clean Harbors has identified the remediation of Per- and Polyfluoroalkyl Substances (PFAS) as a significant growth area, with a projected 20% growth rate factored into its 2026 guidance. Increased regulatory focus and legislative action surrounding "forever chemicals" are expected to fuel substantial demand in this specialized service offering.
  • Strategic Acquisitions and Fleet Expansion: Recent corporate actions, such as the agreement to acquire environmental businesses from Depot Connect International for approximately $130 million (expected to add $40 million in annual revenue), and a $50 million strategic investment in fleet expansion, are poised to directly contribute to revenue growth by increasing capacity and expanding service offerings.
  • High Utilization of Disposal Network and Remediation Project Pipeline: The company anticipates sustained high demand for its extensive network of disposal and recycling facilities, including its incinerators, which have demonstrated pricing power. Furthermore, a growing pipeline of large-scale remediation and project work, including potential opportunities arising from "reshoring" trends, is expected to be a significant driver of revenue.
