Sono-Tek Corporation (SOTK): fair value, margin of safety and Wheel Score
Industrials · Industrial - Machinery · United States · Quality / Blue-Chip
Is SOTK undervalued?
Sono-Tek Corporation (SOTK) closed at 6.21 on 16 Oct 2026. The GLS average fair value - the simple average of the 8 valuation models that produced a positive number - is 13.39, which puts the price 54% below it. 4 of the 8 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.
There is a wide gap between EPV (1.42) and Graham Number (62.01). 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 SOTK under Quality / Blue-Chip: a high moat score and a high health score together.

Quality and financial health
Sono-Tek Corporation 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 8.0/10 puts SOTK 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 9.1%, ROE 9.1%, ROA 6.8% - with debt at 0.00 times equity and a free-cash-flow yield of 7.4%.
Sono-Tek Corporation 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 Integrated Coating Systems 76%, Multi Axis Coating Systems 17%, Fluxing Systems 4% (quarter Q1 FY2026).
Institutional ownership scores 1/10, insider activity 6/10 and Congressional trading 5/10 on the GLS smart-money scales.
| Piotroski F-score | 7 / 9 | ROIC | 9.1% |
|---|---|---|---|
| GLS Moat | 8.0 / 10 | ROE | 9.1% |
| Debt / equity | 0.00 | ROA | 6.8% |
| Free-cash-flow yield | 7.4% | Payout ratio | 0% |
| Institutions | 1 / 10 | Insiders · Congress | 6 · 5 / 10 |
Wheel Score 39: No options
No options are listed on Sono-Tek 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 387k shares a day on a market cap of $98M, with a beta of -0.02 - a low beta, so day-to-day moves are smaller than the market's; the Stability part of the Wheel Score gives that 10 of 20.
| Part | Points | From | |
|---|---|---|---|
| Value | 25 / 25 | 54% margin of safety | |
| Health | 16 / 20 | Piotroski 7/9 | |
| Moat | 12 / 15 | moat 8.0/10 | |
| Premium | 0 / 20 | no option data | |
| Stability | 10 / 20 | 387k shares/day, $98M cap, beta -0.02 |
