Update on the Receivership Procedure

Lyon (France) –April 24, 2025 at 6 pm CEST – PHAXIAM Therapeutics (Euronext: PHXM - FR001400K4B1), a biopharmaceutical company ("the Company" or "PHAXIAM") developing innovative treatments for severe and resistant bacterial infections, announces that it has received two bids as part of a disposal plan, following the bidding process (appel d'offres) launched within the framework of the receivership procedure opened on March 6, 2025.

At this stage, these two offers are not yet admissible.

In this context, the court-appointed administrator (administrateur judiciaire) has filed a request to convert the proceedings into judicial liquidation.

The coming days will determine whether the bids can be made admissible or whether judicial liquidation must be pronounced swiftly in order to avoid further deterioration of the Company's cash position.

As a reminder, whether or not a bid is accepted, the Commercial Court of Lyon will in any case soon pronounce the judicial liquidation of the Company. In this context, the Company will request the delisting of PHAXIAM shares from Euronext.

Furthermore, PHAXIAM draws investors' attention to the fact that, given the Company's level of indebtedness, the proceeds from any disposal, should a takeover bid be accepted, will most likely not allow for any repayment to shareholders.
