AI Analysis

I look for durable businesses, honest financials, and a price that offers a margin of safety. Clean Harbors has a real advantage: hazardous-waste collection, treatment, incineration, and disposal are regulated, permit-heavy services that customers cannot easily switch away from. That makes revenue more recurring and gives the company some pricing power. Financial health is respectable. FairStock calculates a Piotroski F-Score of 8/9, an Altman Z-Score of 3.12, ROE of 15.56%, and a beta of 0.85. Still, debt/equity of 1.11 and ROCE of 6.07% show this is a capital-intensive business with only moderate returns on total capital. Growth has been uneven. In fiscal year 2025, the year ended 2025-12-31, revenue was $6.0B, net income $391.0M, and diluted EPS $7.28. In fiscal year 2024, the year ended 2024-12-31, revenue was $5.9B, net income $402.3M, and diluted EPS $7.42, so annual profit slipped even as sales rose. FairStock labels it a fast grower because its computed five-year profit growth was 23.7% a year and revenue growth 13.9%. The valuation is the problem. At the 2026-10-13 close of $317.38, FairStock shows P/E 38.52, P/B 5.72, FCF yield 2.7%, EV/EBITDA 15.92, PEG 1.12, and a Graham Number of $101.37, implying a margin of safety of -213.09%. The company is better than average; the price already assumes a lot. I prefer waiting for a wider discount.

In plain English: Clean Harbors collects, treats, and safely disposes of hazardous and industrial waste in the U.S. and Canada. The business looks financially sturdy, with growing sales and strong financial-health scores, but it also uses a fair amount of debt. At the recent price, the stock looks expensive compared with the company's current profits and asset value.
