Provides environmental and industrial services in the United States and Canada.

• The growing urgency and evolving regulatory landscape around PFAS and hazardous waste management is expected to create a multibillion-dollar opportunity, and Clean Harbors' unique position as the only company with end-to-end PFAS destruction capabilities positions it to capture significant long-term revenue and margin growth as new government and corporate standards take effect.
  
• Ongoing reshoring, manufacturing expansion, and infrastructure build-out in North America are expected to structurally increase the volume and complexity of industrial waste, expanding Clean Harbors' addressable market and supporting sustained revenue growth and network utilization.
  
• The company's ongoing investment in facility expansion (e.g., Kimball, Phoenix hub), logistics optimization, and advanced technology is driving operating leverage, improving route density, and supporting margin expansion as network scale and efficiency increase.
  
• The shift towards circular economy solutions and sustainability, including growth in Safety-Kleen Sustainability Solutions and resource recovery, is expected to generate higher recurring revenue and earnings stability as corporations and fleets migrate to lower-carbon and closed-loop models.
  
• Active capital deployment-both for bolt-on M&A and organic growth-combined with a strong balance sheet and cost discipline, is expected to unlock further growth and long-term free cash flow, with management signaling substantial capital deployment that should drive both top-line and margin expansion.

Clean Harbors Future Earnings and Revenue Growth

Assumptions

• Analysts are assuming Clean Harbors's revenue will grow by 5.7% annually over the next 3 years.
• Analysts assume that profit margins will increase from 6.5% today to 8.6% in 3 years time.
• Analysts expect earnings to reach $605.1 million (and earnings per share of $11.54) by about September 2028, up from $384.8 million today. The analysts are largely in agreement about this estimate.
• In order for the above numbers to justify the analysts price target, the company would need to trade at a PE ratio of 28.3x on those 2028 earnings, down from 33.0x today. This future PE is greater than the current PE for the US Commercial Services industry at 25.7x.
• Analysts expect the number of shares outstanding to decline by 0.49% per year for the next 3 years.
• To value all of this in today's terms, we will use a discount rate of 7.27%, as per the Simply Wall St company report.

Clean Harbors Future Earnings Per Share Growth

Risks

• Acceleration of zero-waste and circular economy initiatives could reduce the volume of hazardous waste generated by manufacturers and industrial facilities, which would shrink Clean Harbors' revenue base over time and dampen long-term top-line growth.
  
• Advancements in environmentally-friendly manufacturing and decarbonization efforts, including source reduction and alternative disposal technologies, may decrease the need for incineration and landfill services-impacting Clean Harbors' core disposal segments, potentially leading to reduced revenue and earnings.
  
• Increasing regulatory scrutiny and permitting obstacles for new and existing incinerators and landfills may constrain Clean Harbors' ability to expand or fully optimize capacity, leading to higher compliance costs, capital expenditures, and potential margin compression over the long run.
  
• Significant capital investments are continuously required to upgrade, maintain, and comply with evolving regulatory requirements for treatment, storage, and disposal facilities (including PFAS and new hub rollouts), which could pressure free cash flow and increase leverage or interest expense-especially if revenue growth stalls.
  
• Potential technological disruption from emerging waste remediation and recycling technologies (such as alternative PFAS destruction methods or new sustainable processes) could erode demand for Clean Harbors' legacy services, negatively impacting revenue mix, net margins, and long-term earnings growth.

Valuation

• The analysts have a consensus price target of $266.556 for Clean Harbors based on their expectations of its future earnings growth, profit margins and other risk factors. However, there is a degree of disagreement amongst analysts, with the most bullish reporting a price target of $305.0, and the most bearish reporting a price target of just $240.0.
• In order for you to agree with the analyst's consensus, you'd need to believe that by 2028, revenues will be $7.0 billion, earnings will come to $605.1 million, and it would be trading on a PE ratio of 28.3x, assuming you use a discount rate of 7.3%.
• Given the current share price of $236.5, the analyst price target of $266.56 is 11.3% higher.
• We always encourage you to reach your own conclusions though. So sense check these analyst numbers against your own assumptions and expectations based on your understanding of the business and what you believe is probable.
