Amarin Corporation plc (AMRN): fair value, margin of safety and Wheel Score
Healthcare · Drug Manufacturers - General · Ireland · ADR · Speculative / Distressed
Is AMRN undervalued?
AMRN has a margin of safety of 77%: the stock closed at 11.57 on 16 Oct 2026 against a GLS average fair value of 49.88. 1 of the 1 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.
Only 1 of the nine models produced a value (10 Cap); 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 AMRN 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 AMRN
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 | 49.88 | +331% | Owner's earnings (operating cash flow less maintenance capex) capitalised at 10% |
| 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) | 21.20 | +83% | Current assets less all liabilities, per share: the balance-sheet floor. Not in the average |
| Wall St target | 2.17 | -81% | Analysts' average 12-month price target. Not in the average |
Quality and financial health
Financial health is weak: AMRN passes 3 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 1.8 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 -8.2%, ROE -8.4%, ROA -5.8% - with debt at 0.03 times equity and a free-cash-flow yield of 20.5%.
Amarin Corporation plc 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 Product 93%, Licensing And Royalty 7% (quarter Q2 FY2026).
Institutional ownership scores 3/10, insider activity 5/10 and Congressional trading 5/10 on the GLS smart-money scales.
| Piotroski F-score | 3 / 9 | ROIC | -8.2% |
|---|---|---|---|
| GLS Moat | 1.8 / 10 | ROE | -8.4% |
| Debt / equity | 0.03 | ROA | -5.8% |
| Free-cash-flow yield | 20.5% | Payout ratio | 0% |
| Institutions | 3 / 10 | Insiders · Congress | 5 · 5 / 10 |
Wheel Score 45: Weak
AMRN scores 45 out of 100 on the Wheel Score, in the Weak band (under 50), capped at 45 because the engine files it as Speculative / Distressed. Value 25/25, Health 7/20, Moat 3/15, Premium 17/20, Stability 6/20. 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 71% 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 3,091 contracts across all expiries - enough for the wheel at normal size.
Volume runs at 54k shares a day on a market cap of $239M, with a beta of 0.77 - a low beta, so day-to-day moves are smaller than the market's; the Stability part of the Wheel Score gives that 6 of 20.
| Part | Points | From | |
|---|---|---|---|
| Value | 25 / 25 | 77% margin of safety | |
| Health | 7 / 20 | Piotroski 3/9 | |
| Moat | 3 / 15 | moat 1.8/10 | |
| Premium | 17 / 20 | implied volatility 71% | |
| Stability | 6 / 20 | 54k shares/day, $239M cap, beta 0.77 |
