Clean Harbors, Inc. (CLH): fair value, margin of safety and Wheel Score
Industrials · Waste Management · United States · Quality / Blue-Chip
Is CLH undervalued?
Clean Harbors, Inc. (CLH) closed at 319.78 on 16 Oct 2026, 158% above the GLS average fair value of 123.73. 8 of the 8 models that produced a number value the shares below the current price. A gap this wide usually means the market is paying for growth or a story the trailing numbers do not show yet; the models work from filed results, not forecasts, so they are conservative by design.
There is a wide gap between GLS Growth (74.72) and Graham Growth (244.64). When the models are this far apart the "fair value" is really a range, and the margin of safety above should be read with that range in mind.
The nightly engine files CLH under Quality / Blue-Chip: a high moat score and a high health score together.

Quality and financial health
Clean Harbors, Inc. scores 7 of 9 on the Piotroski F-score, the nine yes/no tests of profitability, leverage and efficiency on the latest annual accounts - a strong reading that passes the Sunday Scan's "6 or more" rule with room to spare. A GLS Moat score of 8.6/10 puts CLH among the more durable businesses we track: over ten years the metrics the score watches (revenue, EPS, book value, margins, cash flow, ROIC) have mostly moved the right way, year after year.
Returns on capital are moderate - ROIC 6.3%, ROE 14.2%, ROA 5.1% - with debt at 1.26 times equity and a free-cash-flow yield of 1.2%.
Clean Harbors, Inc. pays no dividend, so the DDM model does not apply and a covered-call holder earns only the premium and any price gain. Revenue comes mainly from Technical Services 31%, Safetly Kleen Environmental Services 22%, Industrial Services And Other 21% (quarter Q2 FY2026).
Institutional ownership scores 10/10, insider activity 1/10 and Congressional trading 1/10 on the GLS smart-money scales.
| Piotroski F-score | 7 / 9 | ROIC | 6.3% |
|---|---|---|---|
| GLS Moat | 8.6 / 10 | ROE | 14.2% |
| Debt / equity | 1.26 | ROA | 5.1% |
| Free-cash-flow yield | 1.2% | Payout ratio | 0% |
| Institutions | 10 / 10 | Insiders · Congress | 1 · 1 / 10 |
Wheel Score 65: Good
With a Wheel Score of 65 - the Good band - Clean Harbors, Inc. falls just short of the Sunday Scan's "70 or higher" rule. The parts: Value 0/25, Health 16/20, Moat 13/15, Premium 19/20, Stability 17/20; Value (0/25) scores lowest.
Implied volatility is 34% on the near-the-money contracts 20-60 days out: some premium, but under the 35-60% range the Wheel Score pays full marks for (19 of 20 points). Chain open interest is thin - 1,388 contracts across every expiry - so fills at a fair price are not guaranteed; a 30-45-day put may not exist at a usable strike.
Volume runs at 628k shares a day on a market cap of $16.9B, with a beta of 0.88; the Stability part of the Wheel Score gives that 17 of 20.
| Part | Points | From | |
|---|---|---|---|
| Value | 0 / 25 | -158% margin of safety | |
| Health | 16 / 20 | Piotroski 7/9 | |
| Moat | 13 / 15 | moat 8.6/10 | |
| Premium | 19 / 20 | implied volatility 34% | |
| Stability | 17 / 20 | 628k shares/day, $16.9B cap, beta 0.88 |
