OPAL Fuels Inc. (OPAL): fair value, margin of safety and Wheel Score
Industrials · Engineering & Construction · United States · High Growth
Is OPAL undervalued?
OPAL Fuels Inc. (OPAL) closed at 1.57 on 16 Oct 2026. The GLS average fair value - the simple average of the 5 valuation models that produced a positive number - is 16.84, which puts the price 91% below it. 5 of the 5 models value the shares above the current price. A gap this wide is rare in our universe of ~7,400 US stocks and is exactly what the Value part of the Wheel Score rewards; it is also where the question "why is it this cheap?" matters most.
The 5 models disagree widely: Graham Number gives 3.55 while GLS Growth gives 38.62. A spread that wide means the average is sensitive to which methods you trust; the model table below shows where each one lands, and the Quote page lets you switch any of them off.
The nightly engine files OPAL under High Growth: revenue and earnings growing fast enough that the growth-based models carry the valuation.

Quality and financial health
Financial health is average - OPAL passes 5 of the nine Piotroski tests, which falls one point short of the Sunday Scan's "6 or more" rule. The Financials tab on the Quote page shows which tests fail. The GLS Moat score is low at 3.0 out of 10, which says the ten-year record of revenue, earnings, margins and returns on capital has been inconsistent - growth and shocks rather than steady compounding.
Returns on capital are thin or negative - ROIC 4.2%, ROE -114.1%, ROA 1.5% - with debt at -28.26 times equity and negative free cash flow.
OPAL Fuels 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 Environmental Credits 75%, Service 13%, Electricity 12% (quarter Q3 FY2025).
Institutional ownership scores 7/10, insider activity 10/10 and Congressional trading 5/10 on the GLS smart-money scales.
| Piotroski F-score | 5 / 9 | ROIC | 4.2% |
|---|---|---|---|
| GLS Moat | 3.0 / 10 | ROE | -114.1% |
| Debt / equity | -28.26 | ROA | 1.5% |
| Free-cash-flow yield | -97.7% | Payout ratio | 67% |
| Institutions | 7 / 10 | Insiders · Congress | 10 · 5 / 10 |
Wheel Score 53: Fair
OPAL scores 53 out of 100 on the Wheel Score (Fair band, 50-64): a usable but unremarkable fit for the wheel strategy. The parts: Value 25/25, Health 11/20, Moat 5/15, Premium 5/20, Stability 7/20. Premium (5/20) is where the points are missing.
Implied volatility is 178%, far above the range the wheel strategy is built for. The premium looks generous; the Wheel Score gives it only 5 of 20 Premium points because moves of that size can blow through any strike. Chain open interest is thin - 1,716 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 162k shares a day on a market cap of $48M, with a beta of 0.79 - a low beta, so day-to-day moves are smaller than the market's; the Stability part of the Wheel Score gives that 7 of 20.
| Part | Points | From | |
|---|---|---|---|
| Value | 25 / 25 | 91% margin of safety | |
| Health | 11 / 20 | Piotroski 5/9 | |
| Moat | 5 / 15 | moat 3.0/10 | |
| Premium | 5 / 20 | implied volatility 178% | |
| Stability | 7 / 20 | 162k shares/day, $48M cap, beta 0.79 |
