# Amarin Corporation plc (AMRN) fundamentals

## Valuation
- **P/E (trailing): n/a** (negative earnings). Amarin Corporation plc reported negative earnings over the last twelve months, so the P/E is not meaningful; use price-to-sales, EV/EBITDA and free-cash-flow yield instead.
- **PEG: 0.26**. A PEG of 0.26 means the P/E is low relative to expected earnings growth: the market is not paying much for that growth.
- **Price / sales: 1.6×**. Each dollar of revenue is priced at 1.6×.
- **Price / book: 0.7×**. The shares trade below book value, which can signal a bargain or a balance sheet the market doubts.

## Profitability
- **Gross margin: 42.0%**. Amarin Corporation plc keeps 42.0% of revenue after the direct cost of what it sells.
- **Operating margin: -21.9%**. Operating margin is negative: the business loses money before interest and tax.
- **Net margin: -18.2%**. The company reported a net loss over the last twelve months.
- **Return on equity: -8.4%**. Return on equity is negative because earnings are negative.
- **Return on invested capital: -8.6%**. Return on all capital, debt included, is -8.6%: close to or below the cost of capital, so growth may not create value.

- **EPS growth (1 yr): 55.0%**. Earnings per share rose 55.0%, faster than revenue, so margins expanded or the share count shrank.

## Financial health
