Forte Biosciences (FBRX) is back in focus after reporting statistically significant phase 1b data for FB102 in vitiligo, with early and sustained FVASI improvements and a safety profile that compared favorably to placebo.

Forte Biosciences has seen sharp positive momentum build around these FB102 results, with the 1 month share price return of 173.73% and year to date share price return of 106.95% contributing to a very large 1 year total shareholder return of 379.96%, even though the 5 year total shareholder return is down 93.55%.

Forte Biosciences now carries a market value of about US$1.19b after the FB102 surge, yet the company reports no revenue and a net loss of US$75.86m. How are investors currently pricing that trade off?

Preferred Price-to-Book Multiple of 28.4x: Is It Justified?

With Forte Biosciences now trading at $48.86, the stock is being valued at a P/B ratio of 28.4x, which stands well above peers and raises questions about what investors are paying for.

The price to book ratio compares a company’s market value to its net assets, so a higher P/B typically suggests the market is assigning a premium over the stated book value. For a clinical stage biopharma company like Forte Biosciences, that usually reflects expectations around the pipeline and future optionality rather than current earnings or revenue, especially as the company is unprofitable and reports no revenue.

In this case, the gap compared with both similar companies and the broader US Biotechs industry is particularly wide. Forte Biosciences trades on a P/B of 28.4x, versus an average of 4.6x for peers and 2.6x for the US Biotechs industry. This indicates investors are paying a much higher multiple of book value than is typical in the sector.

Result: Price-to-book of 28.4x (OVERVALUED)

However, Forte Biosciences still carries execution risk around FB102’s clinical path, while ongoing losses of US$75.86m and no revenue leave little margin for disappointment.
