DBV Technologies Announces Sale of approximately $30 million of ADSs Through its At-The-Market (ATM) Program on Nasdaq

DBV Technologies (Euronext: DBV – ISIN: FR0010417345 – Nasdaq Capital Market: DBVT) (the “Company”), a clinical-stage biopharmaceutical company, today announced that, pursuant to the Company’s At-The-Market program established on September 5, 2025 (the “ATM Program”), it has agreed to issue and sell new ordinary shares (the “Ordinary Shares”) in the form of American Depositary Shares (“ADSs”), for total gross proceeds to the Company of approximately $30 million, before deducting sales agent commissions and offering expenses payable by the Company, to Invus (“Invus”) through Citizens Capital Markets, acting as sales agent. Each ADS represents the right to receive five Ordinary Shares of the Company.

Under the ATM Program, and in accordance with the provisions of Article L.225-138 of the French Commercial Code (Code de commerce) and pursuant to the 25th resolution adopted by the Annual General Meeting of Shareholders held on June 11, 2025, 11,538,460 new Ordinary Shares (underlying 2,307,692 new ADSs) will be issued through a capital increase without preferential subscription rights of the shareholders reserved to specific categories of persons fulfilling certain characteristics (the “ATM Issuance”), at an at-the-market price of $13.00 per ADS (i.e., a subscription price per Ordinary Share of €2.2264 based on the USD/EUR exchange rate of $1.1678 for €1, as published by the European Central Bank on October 6, 2025) and each ADS giving the right to receive 5 Ordinary Shares of the Company, representing a discount, which discount primarily reflects trading fluctuations between Nasdaq and Euronext Paris, as well as foreign exchange effects, of 3.41% to the last closing price of the Company’s shares on the regulated market of Euronext in Paris (“Euronext Paris”) preceding the setting of the issue price (i.e., €2.305).

The issuance and delivery of the new Ordinary Shares is expected to take place on October 8, 2025. The ADSs will be admitted to trading on Nasdaq Capital Market (“Nasdaq”) and the new Ordinary Shares on Euronext Paris. The new Ordinary Shares will represent 8.42% of the existing shares already admitted to trading on Euronext Paris, representing less than 30% of the ordinary shares already admitted to trading on Euronext Paris without a French listing prospectus or an exemption document over a rolling period of 12 months.

The new Ordinary Shares will represent a dilution of approximately 7.77% upon completion of the transaction.

A shelf registration statement on Form S-3 (including a prospectus) relating to the ADSs was filed with the SEC and has been declared effective. Before purchasing ADSs in the offering, prospective investors should read the prospectus supplement and the accompanying prospectus, together with the documents incorporated by reference therein. Prospective investors may obtain these documents for free by visiting EDGAR on the SEC’s website at www.sec.gov.

No prospectus will be subject to the approval of the French Financial Markets Authority (the Autorité des Marchés Financiers or the “AMF”) pursuant to Regulation (EU) 2017/1129 of the European Parliament and of the Council dated June 14, 2017, as amended (the “Prospectus Regulation”) since the contemplated share capital increase (for the issuance of the Ordinary Shares underlying the ADSs) is offered to qualified investors (as such term is defined in Article 2(e) of the Prospectus Regulation) and fall under the exemption provided for in Article 1(5)(a) of the Prospectus Regulation which states that the obligation to publish a prospectus shall not apply to admission to trading on a regulated market of securities fungible with securities already admitted to trading on the same regulated market, provided that they represent, over a rolling period of 12 months, less than 30% of the number of securities already admitted to trading on the same regulated market. 

The share capital of the Company prior to, and after, the ATM Issuance is the following:

About DBV Technologies
DBV Technologies is a clinical-stage biopharmaceutical company developing treatment options for food allergies and other immunologic conditions with significant unmet medical need. DBV Technologies is currently focused on investigating the use of its proprietary technology platform, Viaskin, to address food allergies, which are caused by a hypersensitive immune reaction and characterized by a range of symptoms varying in severity from mild to life-threatening anaphylaxis. Millions of people live with food allergies, including young children. Through epicutaneous immunotherapy (EPIT), the Viaskin platform is designed to introduce microgram amounts of a biologically active compound to the immune system through intact skin. EPIT is a new class of non-invasive treatment that seeks to modify an individual’s underlying allergy by re-educating the immune system to become desensitized to allergen by leveraging the skin’s immune tolerizing properties. DBV Technologies is committed to transforming the care of food allergic people. The Company’s food allergy programs include ongoing clinical trials of Viaskin Peanut in peanut allergic toddlers (1 through 3 years of age) and children (4 through 7 years of age).

DBV Technologies is headquartered in Châtillon, France, with North American operations in Warren, NJ. The Company’s ordinary shares are traded on segment B of Euronext Paris (DBV, ISIN code: FR0010417345) and the Company’s ADSs (each representing five ordinary shares) are traded on the Nasdaq Capital Market (DBVT – CUSIP: 23306J309).
