# SI-BONE Inc. (SIBN) fundamentals

Data as of 2026-09-08. NASDAQ, United States. Sector: Healthcare / Medical Devices. Price $18.50, market value $829 million.

## Valuation
- **P/E (trailing): n/a** (negative earnings). SI-BONE 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: 3.9×**. Each dollar of revenue is priced at 3.9×.
- **Price / book: 4.5×**. The shares trade at 4.5× book value; book value is a meaningful part of the valuation.
- **Free-cash-flow yield: -0.5%** (5-yr avg -5.1%). Free cash flow is negative: the business is consuming cash, which is normal for heavy investment phases but a warning otherwise.

## Profitability
- **Gross margin: 79.5%**. SI-BONE Inc. keeps 79.5% of revenue after the direct cost of what it sells, the kind of margin that comes with software, brands or pricing power.
- **Operating margin: -8.3%**. Operating margin is negative: the business loses money before interest and tax.
- **Net margin: -9.4%**. The company reported a net loss over the last twelve months.
- **Return on equity: -10.6%**. Return on equity is negative because earnings are negative.
- **Return on invested capital: -8.2%**. Return on all capital, debt included, is -8.2%: close to or below the cost of capital, so growth may not create value.
- **Return on assets: -6.1%**. Each dollar of assets produces -6.1% of profit.

## Growth
- **Revenue growth (1 yr): 20.2%** (3-yr 23.6%/yr, 5-yr 22.3%/yr). Revenue grew 20.2% over the last year, against 22.3% a year compounded over five years.
- **EPS growth (1 yr): 41.3%**. Earnings per share rose 41.3%, faster than revenue, so margins expanded or the share count shrank.

## Financial health
- **Debt to equity: 0.20**. Debt is 0.20 times equity: a conservative balance sheet.
- **Net debt / EBITDA: 0.6×**. It would take 0.6 years of operating earnings to repay net borrowings, within the comfortable range.
- **Altman Z-score: 9.73**. A Z-score of 9.73 places the company in the safe zone for bankruptcy risk.
