Disc Medicine, Inc. (IRON): fair value, margin of safety and Wheel Score
Healthcare · Biotechnology · United States · Speculative / Distressed
Is IRON undervalued?
Disc Medicine, Inc. (IRON) closed at 56.65 on 16 Oct 2026, 2356% above the GLS average fair value of 2.31. 1 of the 1 models that produced a number value the shares below the current price. A gap this wide usually means the market is paying for growth or a story the trailing numbers do not show yet; the models work from filed results, not forecasts, so they are conservative by design.
Only 1 of the nine models produced a value (DCF); the others need a dividend, positive free cash flow or positive book value the company does not have yet, so the average rests on a narrow base.
The nightly engine files IRON 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 IRON
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 | 2.31 | -96% | Present value of the projected free cash flows, discounted at the cost of capital |
| 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) | 19.19 | -66% | Current assets less all liabilities, per share: the balance-sheet floor. Not in the average |
| Wall St target | 106.00 | +87% | Analysts' average 12-month price target. Not in the average |
Quality and financial health
Financial health is weak: IRON passes 1 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 0.8 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 -28.6%, ROE -28.7%, ROA -26.3% - with debt at 0.00 times equity and negative free cash flow.
Disc Medicine, Inc. 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 10/10, insider activity 1/10 and Congressional trading 5/10 on the GLS smart-money scales; the last recorded insider buy was on 15 Sep 2026.
| Piotroski F-score | 1 / 9 | ROIC | -28.6% |
|---|---|---|---|
| GLS Moat | 0.8 / 10 | ROE | -28.7% |
| Debt / equity | 0.00 | ROA | -26.3% |
| Free-cash-flow yield | -9.1% | Payout ratio | 0% |
| Institutions | 10 / 10 | Insiders · Congress | 1 · 5 / 10 |
Wheel Score 20: Weak
IRON scores 20 out of 100 on the Wheel Score, in the Weak band (under 50). Value 0/25, Health 2/20, Moat 1/15, Premium 5/20, Stability 12/20. 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 203%, 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 44,201 contracts across all expiries - enough for the wheel at normal size.
Volume runs at 692k shares a day on a market cap of $2.2B, with a beta of 2.05 - 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 12 of 20.
| Part | Points | From | |
|---|---|---|---|
| Value | 0 / 25 | -2356% margin of safety | |
| Health | 2 / 20 | Piotroski 1/9 | |
| Moat | 1 / 15 | moat 0.8/10 | |
| Premium | 5 / 20 | implied volatility 203% | |
| Stability | 12 / 20 | 692k shares/day, $2.2B cap, beta 2.05 |
