DBV Technologies Announces Plan to Implement ADS Ratio Change

DBV Technologies (Euronext: DBV – ISIN: FR0010417345 – Nasdaq Stock Market: DBVT—CUSIP: 23306J200), a clinical-stage biopharmaceutical company focused on treatment options for food allergies and other immunologic conditions with significant unmet medical need, today announced plans to change the ratio of its American Depositary Shares ("ADSs”) to its ordinary shares (the "ADS Ratio”), nominal value €0.10 (ten cents) per share, from the current ADS Ratio of one (1) ADS to one (1) ordinary share to a new ADS Ratio of one (1) ADS to five (5) ordinary shares (the "ADS Ratio Change”). The Company anticipates that the ADS Ratio Change will be effective on or about November 29, 2024 (the "Effective Date”).

For the Company’s ADS holders, the change in the ADS Ratio will have the same effect as a one-for-five reverse ADS split and is intended to enable the Company to regain compliance with the Nasdaq minimum bid price requirement. On the Effective Date, registered holders of the Company’s ADSs held in certificated form will be required on a mandatory basis to surrender their certificated ADSs to the depositary bank for cancellation and will receive one (1) new ADS in exchange for every five existing ADSs surrendered. Holders of uncertificated ADSs in the Direct Registration System ("DRS”) and in The Depository Trust Company ("DTC”) will have their ADSs automatically exchanged and need not take any action. The exchange of every five existing ADSs then-held for one (1) new ADS will occur automatically, at the Effective Date, with the then-held ADSs being cancelled and new ADSs being issued by the depositary bank. DBV’s ADSs will continue to be traded on the Nasdaq Stock Market under the ticker symbol "DBVT”.

No fractional new ADSs will be issued in connection with the change in the ADS Ratio. Instead, fractional entitlements to new ADSs will be aggregated and sold by the depositary bank and the net cash proceeds from the sale of the fractional ADS entitlements (after deduction of fees, taxes and expenses) will be distributed to the applicable ADS holders by the depositary bank. The ADS Ratio Change will have no impact on DBV’s underlying ordinary shares, and no ordinary shares will be issued or cancelled in connection with the ADS Ratio Change.

As a result of the change in the ADS Ratio, DBV’s ADS trading price is expected to increase proportionally, although the Company can give no assurance that the ADS trading price after the ADS Ratio Change will be equal to or greater than five times the ADS trading price before the change.

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 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® 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 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 (Ticker: DBV, ISIN code: FR0010417345) and the Company’s ADSs (each representing one ordinary share) are traded on the Nasdaq Capital Select Market (Ticker: DBVT).
