With the shares now at $260.95, an intrinsic value estimate indicating a roughly 25% discount, and only a small gap to the latest analyst target, the key question is whether there is still a buying opportunity here or if the market is already pricing in future growth.

Most Popular Narrative: 10% Overvalued

Clean Harbors' most followed narrative pegs fair value at $260.69, which sits almost on top of the last close at $260.95, leaving little margin either way.

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.

Read the complete narrative.

There is a full playbook behind that PFAS angle, including revenue growth assumptions, margin shifts and a richer future earnings multiple. Curious what underpins that fair value call and how tight the discount rate assumptions really are?

Result: Fair Value of $260.69 (OVERVALUED)

Have a read of the narrative in full and understand what's behind the forecasts.

However, that playbook can fray if zero waste efforts curb hazardous volumes or if new remediation technologies undercut traditional incineration and landfill work sooner than analysts expect.

Another View: Cash Flows Tell a Different Story

While the popular narrative suggests Clean Harbors is about 10% overvalued on earnings assumptions, our DCF model points a different way. At $260.95, the shares sit roughly 25% below an estimated future cash flow value of $349.79. This frames today’s price as a potential gap in sentiment rather than fundamentals. Which signal do you put more weight on: an earnings multiple or the cash flows behind it?
