Environmental Tectonics Corporation (ETCC): fair value, margin of safety and Wheel Score
Industrials · Aerospace & Defense · United States · Value
Is ETCC undervalued?
ETCC has a margin of safety of 61%: the stock closed at 1.93 on 16 Oct 2026 against a GLS average fair value of 4.98. 5 of the 7 valuation models that produced a number sit above the price. Our screens treat a discount this large as a strong starting point for a cash-secured put, not as a verdict - the fair value is a model output, and a wide gap can mean the models are missing something the market knows.
There is a wide gap between EPV (1.40) and Payback Time (8.15). 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 ETCC under Value: positive earnings at a P/E of 18 or less.

Quality and financial health
Environmental Tectonics Corporation scores 5 of 9 on the Piotroski F-score: a middling result that falls one point short of the Sunday Scan's "6 or more" rule. Some of the nine tests on profitability, leverage and efficiency are failed, so the accounts are worth a look before selling a put on the name. A GLS Moat score of 2.5/10 is a weak reading: the ten-year history the score grades (revenue, EPS, book value, margins, cash flow, share count, ROIC) has not been steady, so the Moat part of the Wheel Score contributes little.
Returns on capital are moderate - ROIC 8.7%, ROE 18.8%, ROA 4.5% - with debt at 1.17 times equity and a free-cash-flow yield of 17.5%.
Environmental Tectonics Corporation pays no dividend, so the DDM model does not apply and a covered-call holder earns only the premium and any price gain.
Institutional ownership scores 5/10, insider activity 5/10 and Congressional trading 5/10 on the GLS smart-money scales.
| Piotroski F-score | 5 / 9 | ROIC | 8.7% |
|---|---|---|---|
| GLS Moat | 2.5 / 10 | ROE | 18.8% |
| Debt / equity | 1.17 | ROA | 4.5% |
| Free-cash-flow yield | 17.5% | Payout ratio | 0% |
| Institutions | 5 / 10 | Insiders · Congress | 5 · 5 / 10 |
Wheel Score 39: No options
No options are listed on Environmental Tectonics Corporation in our nightly snapshot. The Wheel Score is therefore capped at 39 (it reads 39) and the stock is left out of every options screen; the fair value and health figures above are still useful for a plain stock position.
Volume runs at 12k shares a day on a market cap of $18M, with a beta of 1.11; the Stability part of the Wheel Score gives that 6 of 20.
| Part | Points | From | |
|---|---|---|---|
| Value | 25 / 25 | 61% margin of safety | |
| Health | 11 / 20 | Piotroski 5/9 | |
| Moat | 4 / 15 | moat 2.5/10 | |
| Premium | 0 / 20 | no option data | |
| Stability | 6 / 20 | 12k shares/day, $18M cap, beta 1.11 |
