On Oct 5, Clean Harbors, Inc. completed the acquisition of EnviroServe Inc. and its affiliates for $470 million, adding remediation, rail services, industrial cleaning, emergency response, and hazardous waste transportation to its portfolio. On the same day, the company also finished a separate purchase of EnviroServe and ES&H for a total of $775 million, expanding its technical and field services divisions and bringing a nationwide waste‑handling network and a strong Gulf‑region emergency response presence. The combined post‑synergy multiple of 8.9 times adjusted EBITDA was highlighted as underscoring the strategic value of the acquisitions. On Oct 5, analysts noted that Clean Harbors’ strong interest‑coverage ratios position it well against rising borrowing costs, a view supported by easing expectations for Federal Reserve rate hikes. The broader market rally on softer labor data was reported to reinforce confidence in Clean Harbors’ financial resilience in a lower‑rate environment.

Reverse DCF

What growth is priced into CLH?

RICH

At today's price, Clean Harbors Inc. needs to grow free cash flow about 24.8% a year for the next 10 years to justify its valuation at a 8.38% cost of capital. Over its actual history it has compounded free cash flow at 14.6% a year, so the market is asking for 10.2 percentage points above its own delivered rate. On that basis CLH looks priced above what its own growth record supports.

Up days (1y)
57%

Clean Harbors Inc. is currently running 15.9% annualised volatility over the last 21 sessions. Measured against CLH's own 13 years of daily returns rather than a market-wide average, that is the 12th percentile — unusually subdued by its own history, against a typical reading of 25.3%. The distinction matters because a number that looks calm for one stock is turbulent for another, and the absolute figure on its own tells you neither.

CLH is trading -1.1% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -23.9%, and the deepest was -64.5% in 2020. The current pullback is therefore shallower than what this stock gives back in a typical year, which is context worth having before treating it as a dislocation.

Price sits +10.8% from its 200-day moving average. Against every other day in its history, that gap ranks at the 60th percentile — a somewhat wider gap than its own norm. Over the past year CLH closed higher on 57% of sessions, and it is currently 3 sessions into a rising streak.

On October specifically: over 13 years of records, CLH finished the month higher 5 of 13 times, with a median return of -4.0% and an average of -0.8%. Its strongest month historically has been November at +3.4% on average, its weakest September at -1.7%. Seasonality is a weak signal on its own — a decade is a small sample and regimes change — but it is a real distribution rather than a rule of thumb.

Overnight risk is measurable too: CLH has opened more than 2% away from the prior close in 138 of 3,267 sessions (4.2% of the time), with the largest gaps running +24.7% and -10.0%. For anyone holding through an event, that rate is a better guide to overnight exposure than the intraday range.

All figures computed from 3,268 daily closes between 2013-10-07 and 2026-10-05, split-adjusted, recomputed daily. Percentiles are against CLH's own 13-year history, not a peer group or index.

What did this article say?
Clean Harbors (CLH) was highlighted as a more attractive investment than Waste Management (WM) due to its broader moat and focus on hazardous waste, emergency spill response, and industrial cleaning. The company’s operations span North America’s hazardous waste disposal, industrial treatment, and chemical incineration, giving it a dominant regulatory position.

The transactions are projected to lift the company’s 2024 earnings per share above $10, reflecting a clear upside trajectory.
