Abivax Announces Full Exercise of Underwriters’ Option to Purchase Additional ADSs, Bringing Gross Proceeds of Offering to $747.5M (€637.5M)
PARIS, France, July 25, 2025 – 08:00 a.m. (CEST) – Abivax SA (Euronext Paris: FR0012333284 – ABVX) (“Abivax” or the “Company”), a clinical-stage biotechnology company focused on developing therapeutics that harness the body’s natural regulatory mechanisms to modulate the immune response in patients with chronic inflammatory diseases, today announces that the underwriters of its offering of 10,156,000 American Depositary Shares (“ADSs”), each representing one ordinary share, €0.01 nominal value per share (each an “Ordinary Share”), of the Company, in the United States (the “Offering”) have exercised in full their option to purchase 1,523,400 additional ADSs (the “Additional ADSs”), each representing one Ordinary Share. The Additional ADSs will be delivered concurrently with the closing of the Offering, which is expected to occur on July 28, 2025.
Following the exercise in full of the option, the total number of ADSs issued in the Offering will amount to 11,679,400 ADSs, resulting in gross proceeds for the Company of approximately $747.5 million (€637.5 million) and estimated net proceeds, after deducting underwriting commissions and estimated offering expenses payable by the Company, of approximately $700.3 million (€597.2 million).
The Company intends to apply the net proceeds from the sale of the Additional ADSs on a pro rata basis to the use of proceeds identified with respect to the base offering.
The offering price of $64.00 per Additional ADS (corresponding to €54.58 per additional Ordinary Share) based on the exchange rate of €1.00 = $1.1726 as published by the European Central Bank on July 23, 2025), is equal to the volume weighted average price of the Ordinary Shares on the regulated market of Euronext in Paris over the last 3 trading sessions preceding the pricing of the Offering (i.e., July 21 to July 23, 2025), plus a premium of 21.0% and has been determined by the Chief Executive Officer upon subdelegation from the Board of Directors pursuant to the 22nd resolution of the Company’s combined shareholders’ meeting held on June 6, 2025.
The Company’s ADSs are listed on the Nasdaq Global Market under the ticker symbol “ABVX.” The Company’s Ordinary Shares are listed on the regulated market of Euronext in Paris under the symbol “ABVX.”

Any person subsequently offering, selling or recommending the Ordinary Shares (a “distributor”) should take into consideration the manufacturers’ type of clients assessment; however, a distributor subject to MiFID II is responsible for undertaking its own target market assessment in respect of the Ordinary Shares offered in the Offering (by either adopting or refining the manufacturers’ type of clients assessment) and determining appropriate distribution channels.
