				PRESS RELEASE

PHAXIAM Therapeutics announces effectiveness of voluntary delisting of American Depositary Shares from Nasdaq Stock Market

Lyon (France) and Cambridge (MA, US), March 11, 2024, at 07:00am CET – PHAXIAM Therapeutics (Nasdaq & Euronext: PHXM), a biopharmaceutical company developing innovative treatments for severe and resistant bacterial infections, today announces that the Company’s voluntary delisting of American Depositary Shares (“ADSs”) representing its ordinary shares from The Nasdaq Capital Market (“Nasdaq”) has become effective. Each ADS represents one ordinary share of the Company. The Company will file a Form 15 with the Securities and Exchange Commission (“SEC”) to suspend its reporting obligations under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), in respect of the ADSs and the ordinary shares. The Company expects that the deregistration of the ADSs under the Exchange Act will become effective 90 days after the filing of the Form 15.

Information for ADS Holders

The Bank of New York Mellon serves as depositary (the “Depositary”) for the Company’s ADS facility. Each ADS represents one ordinary share. PHAXIAM intends to terminate the Amended and Restated Deposit Agreement, dated May 14, 2018, among the Company, the Depositary and owners and holders of ADSs (the “Deposit Agreement”) on May 23, 2024.

Under the terms of the Deposit Agreement, ADS holders will have until at least May 28, 2024, to surrender ADSs for delivery of the underlying ordinary shares. If you surrender ADSs for delivery of the underlying ordinary shares, you must pay a cable fee of $17.50, a cancellation fee of up to $0.05 per American Depositary Receipts (“ADRs”) surrendered and any applicable U.S. or local taxes or governmental charges. To exchange ADSs for the Company’s ordinary shares, ADS holders should instruct their brokers to surrender ADSs to The Bank of New York Mellon (DTC No. 2504). In connection with this surrender, brokers should include ongoing ordinary share delivery instructions in the comments field within DTC, including information such as the name and BIC of the appropriate local bank/broker and/or appropriate delivery code, beneficiary name and account number. U.S. brokers holding ADSs on behalf of their clients, can reach out to DRSettlements@BNYMellon.com for questions regarding the conversion and settlement process.

On or about May 28, 2024, the Depositary may elect to sell the underlying ordinary shares. If the Depositary has sold such shares, holders of ADSs must surrender such securities in order to obtain payment of the sale proceeds of the underlying ordinary shares, net of the expenses of sale, any applicable U.S. or local taxes or government charges and a cancellation fee of up to $0.05 per ADS.

To surrender ADRs, the address of the Depositary is: The Bank of New York Mellon, 240 Greenwich Street, New York, New York 10286, Attention: Depositary Receipt Administration. Registered or overnight mail is the suggested method of delivering ADRs to the Depositary. For Settlement specific inquiries, please contact DRsettlements@bnymellon.com.

Investors may still present ADSs to The Bank of New York Mellon. Investors will receive either the underlying ordinary shares (if those have not yet been sold by the Depositary) or the cash received by the Depositary received upon sale of underlying ordinary shares, net of fees, if those underlying ordinary shares were sold. For more information, investors should contact DRsettlements@bnymellon.com.
