Price-to-Book of 16.7x: Is it justified?

At the current closing price of $79.13, Inhibrx Biosciences is trading at a substantial premium to its sector peers, with a price-to-book ratio of 16.7x.

The price-to-book ratio compares a company’s market value to its net assets. For biotechs and early-stage innovators like Inhibrx, this metric is often scrutinized when the company is still unprofitable. Book value can be a key anchor for valuation in the absence of strong earnings.

In this case, the market is assigning much more value to Inhibrx than to the average biotech company, reflecting intense optimism about its future drug pipeline and commercial potential. Given the industry average price-to-book is just 2.5x and the peer group is at 2.2x, Inhibrx stands out as expensive by any standard. This sharp valuation gap could signal the market’s belief in significant growth, or simply a speculative fervor after trial success. With no available fair ratio from regression analysis, it remains to be seen whether the current valuation will hold as fundamentals evolve.
