## Valuation
- **P/E (trailing): 64.6×** (5-yr avg 54.5×, 3-yr avg 58.6×). Proto Labs Inc. trades at 64.6× trailing earnings, close to its own five-year average of 54.5×. The Industrials median in the September 2026 study was 25.7×. Forward P/E is 34.1×, lower than trailing, so analysts expect earnings to grow.

- **Price / sales: 3.5×**. Each dollar of revenue is priced at 3.5×.
- **Price / book: 2.8×**. The shares trade at 2.8× book value; book value is a meaningful part of the valuation.
- **EV / EBITDA: 26.4×**. Enterprise value is 26.4× operating earnings before depreciation, the multiple that ignores how the company is financed; above 20× is demanding.
