DBV Technologies Files At-The-Market (ATM) Prospectus for Up to $150 Million of Sales

DBV Technologies (Euronext: DBV – ISIN: FR0010417345 – Nasdaq Capital Market: DBVT) (the “Company”), a late-stage biopharmaceutical company, today announced that it has filed a new automatically effective shelf registration statement on Form S-3ASR (the “Registration Statement”) with the U.S. Securities and Exchange Commission (“SEC”), which includes a base prospectus and a sales agreement prospectus supplement refreshing the Company’s previously established at-the-market offering program (the “ATM Program”) by filing a prospectus supplement for sales of up to $150 million of American Depositary Shares (“ADS”).

The ATM Program was established pursuant to a sales agreement dated September 5, 2025, (the “Sales Agreement”) with Citizens JMP Securities, LLC (“Citizens”), acting as sales agent, under which the Company may offer and sell, from time to time, ADSs, each ADS representing five ordinary shares of the Company, having an aggregate offering price of up to $150 million, subject to French regulatory limits. The Company has filed the sales agreement prospectus supplement to refresh the ATM Program for a total aggregate offering price of up to $150 million – carrying forward the registered but unsold ADSs together with additional newly registered capacity – so that $150 million will be available for issuance and sale under the Sales Agreement. The terms and conditions of the ATM Program remain unchanged.

The Company intends to use the net proceeds of any offering of securities primarily for activities associated with manufacturing expansion, our BLAs in ages 4 through 7 and 1 through 3, launch preparation of Viaskin Peanut in ages 4-7, if approved, development of our product candidates, and for working capital and other general corporate purposes. Accordingly, The Company will have significant discretion in the use of any net proceeds.

The Registration Statement, including a base prospectus and the sales agreement prospectus supplement, relating to the Company’s securities, including the ADSs, became automatically effective upon filing with the SEC. Before purchasing ADSs in the offering, prospective investors should read the sales agreement prospectus supplement and the accompanying base 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. Alternatively, a copy of the sales agreement prospectus supplement (and accompanying base prospectus) relating to the offering may be obtained from Citizens JMP Securities, LLC, 1301 Avenue of the Americas, 2nd Floor, New York, NY 10019 or by email at dl-jmp-syndicate@citizensbank.com.

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, as amended (the “Prospectus Regulation”), since the contemplated share capital increase(s) would be offered to qualified investors (as defined in Article 2(e) of the Prospectus Regulation) and fall under the exemption in Article 1(5)(a) of the Prospectus Regulation for securities fungible with securities already admitted to trading on the same regulated market, representing, over a rolling period of 12 months, less than 30% of the securities already admitted to trading on that market.

This press release shall not constitute an offer to sell or the solicitation of an offer to buy these securities, nor shall there be any sale of these securities in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state or jurisdiction. In particular, no public offering of the ADSs will be made in Europe.

About DBV Technologies

DBV Technologies is a late-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 VIASKIN® patch technology 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® Peanut Patch 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 people with food allergies. The Company’s food allergy programs include ongoing clinical trials of VIASKIN® Peanut Patch in toddlers (1 through 3 years of age) and children (4 through 7 years of age) with peanut allergy.

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).
