## Valuation
- **P/E (trailing): n/a** (negative earnings). Aspen Aerogels Inc. 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.
- **Price / sales: 2.0×**. Each dollar of revenue is priced at 2.0×.
- **Price / book: 2.1×**. The shares trade at 2.1× book value; book value is a meaningful part of the valuation.
- **Free-cash-flow yield: 8.4%** (5-yr avg -17.4%). Free cash flow equals 8.4% of the market value, above its five-year average of -17.4%, so the shares are cheaper on cash than they have usually been. Above 5% is generally attractive.

- **Net margin: -143.7%**. The company reported a net loss over the last twelve months.
- **Return on equity: -165.4%**. Return on equity is negative because earnings are negative.
