Clean Energy Fuels Corp. (CLNE): fair value, margin of safety and Wheel Score
Ticker symbol CLNE · Energy · Oil & Gas Refining & Marketing · United States · Speculative
Is CLNE undervalued?
Clean Energy Fuels Corp. (CLNE) closed at 1.57 on 5 Nov 2026. The GLS average fair value - the simple average of the 1 valuation models that produced a positive number - is 2.47, which puts the price 36% below it. 1 of the 1 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.
Only 1 of the nine models produced a value (10 Cap); the others need a dividend, positive free cash flow or positive book value the company does not have yet, so the average rests on a narrow base.
The nightly engine files CLNE under Speculative - it is losing money or its Piotroski health score is 3 or lower - which caps its Wheel Score at 45 and keeps it out of the Sunday Scan.
Nine valuation models for CLNE
Each model turns the latest filed numbers into a value per share; the GLS fair value is the simple average of the ones that produce a positive number. The last two rows are shown for reference and never enter the average. The Quote page lets you switch any model off and add your own margin of safety.
| Model | Value | vs price | What it measures |
|---|---|---|---|
| DCF | - | - | Present value of the projected free cash flows, discounted at the cost of capital; no value tonight |
| Graham Number | - | - | The most a defensive investor pays for the earnings and book value per share; no value tonight |
| Graham Growth | - | - | Graham's growth formula: EPS × (8.5 + 2 × growth), adjusted for bond yields; no value tonight |
| Lynch | - | - | EPS × the earnings growth rate (PEG of 1), growth capped at 25%; no value tonight |
| GLS Growth | - | - | EPS compounded ten years at the blended growth rate, discounted back at 15% a year; no value tonight |
| 10 Cap | 2.47 | +57% | Owner's earnings (operating cash flow less maintenance capex) capitalised at 10% |
| Payback Time | - | - | Eight years of compounded free cash flow: the price at which the business pays for itself; no value tonight |
| DDM | - | - | Dividend discount model: next year's dividend ÷ (10% − 3% growth); needs a dividend; no value tonight |
| EPV | - | - | Earnings power value: current EPS capitalised at 9% with no growth; no value tonight |
| Zombie (liquidation) | -0.6410 | -141% | Current assets less all liabilities, per share: the balance-sheet floor. Not in the average |
| Wall St target | 2.38 | +52% | Analysts' average 12-month price target. Not in the average |
Quality and financial health
Financial health is average - CLNE passes 6 of the nine Piotroski tests, which passes the "Piotroski 6 or more" Wheel Trade Filter. The Financials tab on the Quote page shows which tests fail. The GLS Moat score is low at 1.9 out of 10: returns on capital, margins or the balance sheet have not shown a lasting edge yet - often a young company, a thin-margin business or one that has only recently turned profitable.
Returns on capital are thin or negative - ROIC -33.7%, ROE -39.7%, ROA -21.0% - with debt at 0.18 times equity and a free-cash-flow yield of 6.6%.
Clean Energy Fuels Corp. 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 Product 74%, Station construction sales 13%, Service 12% (quarter Q2 FY2026).
Institutional ownership scores 6/10, insider activity 3/10 and Congressional trading 5/10 on the GLS smart-money scales.
| Piotroski F-score | 6 / 9 | ROIC | -33.7% |
|---|---|---|---|
| GLS Moat | 1.9 / 10 | ROE | -39.7% |
| Debt / equity | 0.18 | ROA | -21.0% |
| Free-cash-flow yield | 6.6% | Payout ratio | 0% |
| Institutions | 6 / 10 | Insiders · Congress | 3 · 5 / 10 |
Wheel Score 36: Weak
CLNE scores 36 out of 100 on the Wheel Score, in the Weak band (under 50): it fails filter 2, a real business, not a gamble - speculative (a loss, or a weak Piotroski score); and filter 7, a premium worth selling - implied volatility 81% (over 80%); and filter 8, big enough - market cap $346M (under $1.0B); and filter 9, not a penny stock - price 1.57 (under $5), and the parts are thin too - value strong, premium fair, moat weak, health good, red flags fair, option trading weak, stability weak. The score is not a judgement on the company; it says the price, quality and premium do not line up for selling puts on it today.
Implied volatility is 81%, above the 80% ceiling of the Wheel Trade Filter on premium. The premium looks generous, but moves of that size can blow through any strike. Chain open interest is 11,024 contracts across all expiries - enough for the wheel at normal size.
Volume runs at 2.3M shares a day on a market cap of $346M, with a beta of 1.88 - a high beta, so the stock tends to move more than the market and a strike can be gapped through; the Stability part of the Wheel Score rates that weak.
| Filter | Wheel Trade Filter | Result | Detail |
|---|---|---|---|
| 1 | Options that actually trade | Passes | Listed options with 1,000+ contracts of open interest and 100+ traded a day |
| 2 | A real business, not a gamble | Fails | speculative (a loss, or a weak Piotroski score) |
| 3 | Below fair value | Passes | Trading below the nine-model average fair value (margin of safety above 0) |
| 4 | Financially healthy | Passes | Piotroski F-score 6 or more out of 9 (a company with no score on file passes) |
| 5 | Can repay its debt | Passes | Long-term debt repaid from 3 years of operating cash flow or less (6 for real estate and utilities; banks and insurers are not judged on it) |
| 6 | No serious red flags | Passes | Red Flags score 60 or more out of 100 (earnings, margins, debt, analysts, filings and price checked the same way for every stock) |
| 7 | A premium worth selling | Fails | implied volatility 81% (over 80%) |
| 8 | Big enough | Fails | market cap $346M (under $1.0B) |
| 9 | Not a penny stock | Fails | price 1.57 (under $5) |
| How it ranks | Rating | From | |
|---|---|---|---|
| Value | Strong | 36% below fair value | |
| Premium | Fair | implied volatility 81% | |
| Moat | Weak | moat 1.9/10 | |
| Health | Good | Piotroski 6/9 | |
