Industrials · Industrial - Pollution & Treatment Controls · United States · Speculative / Distressed
Is FTEK undervalued?
Fuel Tech, Inc. (FTEK) closed at 1.42 on 16 Oct 2026. None of the nine GLS valuation models produced a positive value for the stock - the company lost money over the last twelve months, EPS -0.11 and it pays no dividend - so there is no GLS average fair value and no margin of safety to report. The quality, option and event numbers below still apply; the Quote page's Wall Street View shows what analysts expect instead.
The nightly engine files FTEK under Speculative / Distressed - negative earnings or a Piotroski score of 3 or less - which caps its Wheel Score at 45 and keeps it out of the Sunday Scan.
Nine valuation models for FTEK
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 | - | - | Owner's earnings (operating cash flow less maintenance capex) capitalised at 10%; no value tonight |
| 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) | 0.7925 | -44% | Current assets less all liabilities, per share: the balance-sheet floor. Not in the average |
| Wall St target | 0.0000 | -100% | Analysts' average 12-month price target. Not in the average |
Quality and financial health
Financial health is weak: FTEK passes 2 of the nine Piotroski tests. Our screens drop the stock at the health rule; a low score is often the reason a stock looks cheap on the valuation models. The GLS Moat score is low at 1.9 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 -5.7%, ROE -5.8%, ROA -4.9% - with debt at 0.01 times equity and negative free cash flow.
Fuel Tech, 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 Fuel Chem 64%, Air Pollution Control 36% (quarter Q2 FY2026).
Institutional ownership scores 3/10, insider activity 10/10 and Congressional trading 5/10 on the GLS smart-money scales.
| Piotroski F-score | 2 / 9 | ROIC | -5.7% |
|---|---|---|---|
| GLS Moat | 1.9 / 10 | ROE | -5.8% |
| Debt / equity | 0.01 | ROA | -4.9% |
| Free-cash-flow yield | -2.7% | Payout ratio | 0% |
| Institutions | 3 / 10 | Insiders · Congress | 10 · 5 / 10 |
Wheel Score 36: Weak
FTEK scores 36 out of 100 on the Wheel Score, in the Weak band (under 50). Value 13/25, Health 4/20, Moat 3/15, Premium 5/20, Stability 11/20. 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 140%, 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 2,998 contracts across all expiries - enough for the wheel at normal size.
Volume runs at 721k shares a day on a market cap of $44M, with a beta of 1.28 - 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 gives that 11 of 20.
| Part | Points | From | |
|---|---|---|---|
| Value | 13 / 25 | 0% margin of safety | |
| Health | 4 / 20 | Piotroski 2/9 | |
| Moat | 3 / 15 | moat 1.9/10 | |
| Premium | 5 / 20 | implied volatility 140% | |
| Stability | 11 / 20 | 721k shares/day, $44M cap, beta 1.28 |

Upcoming events
The next earnings report is due on 3 Nov 2026 (after the close), 18 days away; a 30-45-day put sold today would expire after it, which is worth weighing against the premium.
