# Quantum-Si Incorporated (QSI) fundamentals

Data as of 2026-11-10. NASDAQ, United States. Sector: Healthcare / Biotechnology. Price $1.28, market value $281 million.

## Valuation
- **P/E (trailing): n/a** (negative earnings). Quantum-Si Incorporated 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: 222.3×**. Each dollar of revenue is priced at 222.3×, a level that requires very high margins or very fast growth to justify.
- **Price / book: 1.8×**. The shares trade at 1.8× book value; book value is a meaningful part of the valuation.
- **Free-cash-flow yield: -28.9%** (5-yr avg -30.9%). Free cash flow is negative: the business is consuming cash, which is normal for heavy investment phases but a warning otherwise.

## Profitability
- **Gross margin: 34.9%**. Quantum-Si Incorporated keeps 34.9% of revenue after the direct cost of what it sells.
- **Return on equity: -46.0%**. Return on equity is negative because earnings are negative.

## Growth
- **Revenue growth (1 yr): -20.3%**. Revenue fell 20.3% over the last year.
- **EPS growth (1 yr): 28.2%**. Earnings per share rose 28.2%, faster than revenue, so margins expanded or the share count shrank.

## Financial health
- **Current ratio: 7.64** (quick 7.64). Current assets cover the next year's liabilities 7.64 times.
- **Altman Z-score: 7.57**. A Z-score of 7.57 places the company in the safe zone for bankruptcy risk.
