## Valuation
- **P/E (trailing): n/a** (negative earnings). Plug Power 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: 4.1×**. Each dollar of revenue is priced at 4.1×.
- **Price / book: 5.2×**. The shares trade at 5.2× book value; most of the value is in earnings power and intangibles rather than the balance sheet.
- **Free-cash-flow yield: -17.3%** (5-yr avg -35.3%). Free cash flow is negative: the business is consuming cash, which is normal for heavy investment phases but a warning otherwise.

## Profitability
- **Gross margin: -18.5%**. Plug Power Inc. keeps -18.5% of revenue after the direct cost of what it sells, a thin margin typical of retail, distribution and commodity businesses.
- **Operating margin: -172.8%**. Operating margin is negative: the business loses money before interest and tax.
- **Net margin: -229.8%**. The company reported a net loss over the last twelve months.
- **Return on equity: -166.8%**. Return on equity is negative because earnings are negative.
- **Return on invested capital: -165.6%**. Return on all capital, debt included, is -165.6%: close to or below the cost of capital, so growth may not create value.
- **Return on assets: -63.3%**. Each dollar of assets produces -63.3% of profit.

## Financial health

- **Current ratio: 2.31** (quick 2.31). Current assets cover the next year's liabilities 2.31 times.
- **Altman Z-score: 0.45**. A Z-score of 0.45 is in the distress zone, a signal to examine the balance sheet closely.
