NPK International Inc. (NPKI): fair value, margin of safety and Wheel Score
Basic Materials · Construction Materials · United States · High Growth
Is NPKI undervalued?
At 10.67 (close of 16 Oct 2026), NPKI trades within a few percent of the GLS average fair value of 11.29 (5.5% below fair value). 8 models produced a value and they split 4 above the price to 4 below. A stock priced at fair value earns about half of the Wheel Score's Value points; the rest of the score comes from health, moat, premium and stability.
The 8 models disagree widely: DCF gives 0.5451 while GLS Growth gives 28.10. 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 NPKI under High Growth: revenue and earnings growing fast enough that the growth-based models carry the valuation.
Nine valuation models for NPKI
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.

| Model | Value | vs price | What it measures |
|---|---|---|---|
| DCF | 0.5451 | -95% | Present value of the projected free cash flows, discounted at the cost of capital |
| Graham Number | 6.74 | -37% | The most a defensive investor pays for the earnings and book value per share |
| Graham Growth | 16.42 | +54% | Graham's growth formula: EPS × (8.5 + 2 × growth), adjusted for bond yields |
| Lynch | 6.44 | -40% | EPS × the earnings growth rate (PEG of 1), growth capped at 25% |
| GLS Growth | 28.10 | +163% | EPS compounded ten years at the blended growth rate, discounted back at 15% a year |
| 10 Cap | 13.71 | +28% | Owner's earnings (operating cash flow less maintenance capex) capitalised at 10% |
| Payback Time | 13.29 | +25% | Eight years of compounded free cash flow: the price at which the business pays for itself |
| DDM | - | - | Dividend discount model: next year's dividend ÷ (10% − 3% growth); needs a dividend; no value tonight |
| EPV | 5.10 | -52% | Earnings power value: current EPS capitalised at 9% with no growth |
| Zombie (liquidation) | -0.1073 | -101% | Current assets less all liabilities, per share: the balance-sheet floor. Not in the average |

Quality and financial health
On financial health NPKI scores 7/9 (Piotroski): most of the nine tests - positive earnings and cash flow, falling debt, rising margins and turnover - are passed, which is the kind of balance sheet a wheel trader is happy to be assigned. The GLS Moat score is low at 3.7 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 moderate - ROIC 9.3%, ROE 10.2%, ROA 8.1% - with debt at 0.10 times equity and a free-cash-flow yield of 3.1%.
NPK International 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 Industrial Solution 100% (quarter Q2 FY2026).
Institutional ownership scores 5/10, insider activity 1/10 and Congressional trading 5/10 on the GLS smart-money scales.
| Piotroski F-score | 7 / 9 | ROIC | 9.3% |
|---|---|---|---|
| GLS Moat | 3.7 / 10 | ROE | 10.2% |
| Debt / equity | 0.10 | ROA | 8.1% |
| Free-cash-flow yield | 3.1% | Payout ratio | 0% |
| Institutions | 5 / 10 | Insiders · Congress | 1 · 5 / 10 |
Wheel Score 66: Good
NPKI scores 66 out of 100 on the Wheel Score (Good band, 65-79). The score blends the margin of safety (Value, 15/25), Piotroski health (16/20), the GLS moat (6/15), the option premium on offer (17/20) and how easily the stock trades (13/20). Moat (6/15) is the part holding the score back.
Implied volatility is 70% on the near-the-money contracts 20-60 days out - above the 60% ceiling of the sweet spot. Premiums are large, but the Wheel Score tapers the Premium points (17 of 20) because volatility this high usually comes with a reason. Chain open interest is thin - 354 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 809k shares a day on a market cap of $906M, with a beta of 1.30 - 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 13 of 20.
| Part | Points | From | |
|---|---|---|---|
| Value | 15 / 25 | 6% margin of safety | |
| Health | 16 / 20 | Piotroski 7/9 | |
| Moat | 6 / 15 | moat 3.7/10 | |
| Premium | 17 / 20 | implied volatility 70% | |
| Stability | 13 / 20 | 809k shares/day, $906M cap, beta 1.30 |
