Clean Harbors (CLH) has completed a long signaled leadership transition. Founder Alan S. McKim has retired from the board, and long-time director Robert Willett has stepped in as Chairman.

Clean Harbors shares have gained momentum recently, with a 6.86% 1 month share price return building on a 27.58% year to date move and a 35.71% 1 year total shareholder return. This helps frame this leadership transition against a longer period of strong compounding.

After a 35.71% 1 year total shareholder return and fresh leadership at the top, the key tension for Clean Harbors now is simple: is the recent move already pricing in the story, or does the valuation still leave room for more?

Most Popular Narrative: 4.7% Undervalued

Clean Harbors’ most followed narrative pegs fair value at about $325.86 per share, slightly above the recent $310.57 close, which frames the current debate around valuation.

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.

Investors may be curious about the earnings path and margin profile that sit behind that fair value line. The narrative leans on measured revenue growth, firmer profitability, and a future P/E that assumes real staying power.

Result: Fair Value of $325.86 (UNDERVALUED)

However, Clean Harbors’ story can change quickly if new recycling technologies reduce demand for traditional disposal services, or if stricter permitting caps limit facility expansion and utilization.

While the SWS model sees Clean Harbors as trading about 5.5% below its fair value, the current P/E of 41.5x tells a different story. That is well above both the Commercial Services industry at 20.9x and the estimated fair ratio of 21.6x, which points to limited margin for error if growth or margins fall short.
