DBV Technologies Reports First Quarter 2025 Financial Results

(Euronext: DBV ISIN: FR0010417345 Nasdaq Stock Market: DBVT CUSIP: 23306J309), a clinical-stage biopharmaceutical company, today reported financial results for the First Quarter of 2025. The quarterly and three months financial

statements were approved by the Board of Directors on April 30, 2025.

Financial Highlights for the First

Quarter Ended March 31, 2025

The Company s interim condensed consolidated financial statements for

the three months ended March 31, 2025, are prepared in accordance with accounting principles generally accepted in the United States ( U.S. GAAP ).

Cash and Cash Equivalents

Our Condensed Consolidated Financial Statements have been prepared assuming the Company will continue as a going

concern. The going concern assumption contemplates the realization of assets and satisfaction of liabilities in the normal course of business.

Cash and cash equivalents amounted to $13.0 million as of March 31, 2025, compared to $32.5 million as

of December 31, 2024, a net decrease of $19.5 million. This decrease includes $19.7 million of cash used in operating activities, mainly in external clinical trial related expenses, notably progress on subject enrollment in the

VITESSE Phase 3 clinical trial, as well as Regulatory and Manufacturing activities to support ongoing clinical trials.

On March 27, 2025, the company

announced a financing of up to $306.9 million ( 284.5 million), to Advance

Viaskin Peanut Patch through Biologics License Application submission (BLA) and U.S. Commercial Launch, if approved. The financing included gross proceeds of $125.5 million ( 116.3 million) received on April 7, 2025. With the receipt of the aforementioned proceeds, and based on its current operations, plans, and assumptions examined by the Board on March 23,

Company estimates that its cash and cash equivalents are sufficient to fund its operations into June 2026.

The Company has incurred operating losses and negative cash flows from operations since inception. The Company does

not generate product revenue and continues to prepare for the potential launch of its first product in the United States and in the European Union, if approved.

These condensed consolidated financial statements do not include any adjustments to the carrying amounts and

classification of assets, liabilities, and reported expenses that may be necessary if the Company was unable to continue as a going concern.

Operating income amounted to $0.8 million for the three months ended March 31, 2025, compared with

$1.4 million for the same period in 2024 due to a lower French Research Tax Credit entitlement as a greater proportion of study activities were carried out in North America and are therefore not eligible for this tax credit.

Operating expenses amounted to $27.4 million for the three

months ended March 31, 2025, compared with $30 million for the three months ended March 31, 2024, a decrease of $2.6 million. This decrease is primarily driven by lower General & Administrative expenses, notably

$2.2 million expenses associated with office moves in France and the U.S that occurred in 2024.

Net Loss and Net Loss Per Share

The Company recorded a net loss of $27.1 million for the three months ended March 31, 2025, compared to a

net loss of $27.3 million for the three months ended March 31, 2024.

On a per share basis, net loss

(based on the weighted average number of shares outstanding over the period) was $(0.26) for the three months ended March 31, 2025 vs. $(0.28) for the three months ended March 31, 2024.

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

Ch tillon, 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)
