With ABIVAX Société Anonyme posting revenue growth of 55.4% but still reporting a net loss of €336.102 million and trading below analyst price targets, investors now face a key question: is there genuine upside here or is the market already pricing in future growth?
Preferred Price to Book of 18x: Is it justified?
ABIVAX Société Anonyme is currently trading on a P/B of 18x, compared with an industry average of 4.6x, which immediately raises valuation questions when set against the last close at €103.5.
P/B compares a company’s market value to its book value, so an 18x multiple means investors are paying a high price relative to the underlying net assets on the balance sheet. For a clinical stage biotech that is still loss making, that usually reflects expectations around future revenue growth and the potential of the pipeline rather than current earnings power.
Here, the picture is mixed. On one hand, ABIVAX Société Anonyme is described as trading at 86% below an internal fair value estimate based on future cash flows, and revenue is forecast to grow 55.4% per year, ahead of both the French market and the 20% threshold flagged in the data. On the other hand, the company is currently loss making, is forecast to remain unprofitable over the next 3 years, has a negative return on equity of 73.84%, and relies entirely on higher risk external borrowing for funding, with shareholders having been diluted in the past year.
Compared with the French Biotechs industry, where the average P/B is 4.6x, ABIVAX Société Anonyme looks expensive on this preferred multiple by a wide margin. This suggests the market is pricing in much stronger outcomes than for peers. With no fair ratio available to indicate where the P/B might sit if it reverted to a level implied by fundamentals, the gap to the sector average stands out even more clearly.

Result: Price-to-book of 18x (OVERVALUED)
However, the story can change quickly if the Phase 3 and Phase 2b trials for obefazimod disappoint, or if continued losses force further shareholder dilution.
