Assessing Abivax (ENXTPA:ABVX) Valuation After Strong Year-To-Date Gains And Recent Pullback

ABIVAX Société Anonyme (ENXTPA:ABVX) has had a mixed run lately, slipping over the past week but still sitting comfortably above its level from the past 3 months and year to date.

See our latest analysis for ABIVAX Société Anonyme.

Despite a 15.7% seven day share price pullback, ABIVAX Société Anonyme still boasts a powerful year to date share price return and robust one year total shareholder return, which may suggest that longer term momentum is still very much alive.

If ABIVAX has piqued your interest, it is also worth seeing what else is happening across healthcare by exploring healthcare stocks for fresh stock ideas.

Yet with the share price now hovering above analysts’ targets and the company still loss making despite strong growth, investors must ask whether ABIVAX is undervalued today or whether the market already anticipates its future expansion.

Price to Book of 14.9x: Is it justified?

ABIVAX Société Anonyme last closed at €97.60, and its rich price to book ratio of 14.9 times points to a market that is pricing in aggressive expectations compared to peers.

The price to book ratio compares a company’s market value with the accounting value of its net assets. This is a common yardstick for early stage or loss making biotechs where earnings are not yet a reliable guide. A high multiple here suggests investors are focusing on future potential rather than today’s balance sheet.

In ABIVAX’s case, the 14.9 times price to book sits far above both the French Biotechs industry average of 2.6 times and the peer average of 6.6 times. This implies that the market is assigning a substantial premium to its pipeline and forecast revenue growth while overlooking the lack of current profitability.

Result: Price to Book of 14.9x (OVERVALUED)

However, investors should not ignore ABIVAX’s steep losses and premium valuation, as clinical or regulatory setbacks could quickly unwind the current optimism.
