GrafTech International Ltd. (EAF): fair value, margin of safety and Wheel Score
Industrials · Electrical Equipment & Parts · United States · Speculative / Distressed
Is EAF undervalued?
GrafTech International Ltd. (EAF) closed at 7.36 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 -6.75, it pays no dividend and its debts exceed what its assets would fetch - 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 EAF 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 EAF
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) | -30.81 | -519% | Current assets less all liabilities, per share: the balance-sheet floor. Not in the average |
| Wall St target | 7.75 | +5% | Analysts' average 12-month price target. Not in the average |
Quality and financial health
Financial health is weak: EAF 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 0.9 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 -26.3%, ROE 84.7%, ROA -21.4% - with debt at -4.22 times equity and negative free cash flow.
GrafTech International Ltd. 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 by Product 100% (quarter Q1 FY2022).
Institutional ownership scores 1/10, insider activity 5/10 and Congressional trading 5/10 on the GLS smart-money scales.
| Piotroski F-score | 2 / 9 | ROIC | -26.3% |
|---|---|---|---|
| GLS Moat | 0.9 / 10 | ROE | 84.7% |
| Debt / equity | -4.22 | ROA | -21.4% |
| Free-cash-flow yield | -61.1% | Payout ratio | 0% |
| Institutions | 1 / 10 | Insiders · Congress | 5 · 5 / 10 |
Wheel Score 32: Weak
EAF scores 32 out of 100 on the Wheel Score, in the Weak band (under 50). Value 13/25, Health 4/20, Moat 1/15, Premium 6/20, Stability 8/20. 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 117% 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 (6 of 20) because volatility this high usually comes with a reason. Chain open interest is 9,065 contracts across all expiries - enough for the wheel at normal size.
Volume runs at 447k shares a day on a market cap of $192M, with a beta of 1.86 - 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 8 of 20.
| Part | Points | From | |
|---|---|---|---|
| Value | 13 / 25 | 0% margin of safety | |
| Health | 4 / 20 | Piotroski 2/9 | |
| Moat | 1 / 15 | moat 0.9/10 | |
| Premium | 6 / 20 | implied volatility 117% | |
| Stability | 8 / 20 | 447k shares/day, $192M cap, beta 1.86 |
