Financial Highlights for the Full Year 2025

Financial Performance

Operating Income

For the year ended December 31, 2025, operating income totaled $5.6 million, increasing from $4.2 million for the year ended December 31, 2024, driven by higher eligible activities to the French Research Tax Credit (crédit d'impôt recherche).

Research and Development Expenses

R&D expenses increased by $27.3 million for the year ended December 31, 2025, compared to 2024 driven by:

Pre-commercial inventory of $16.1 million, in preparation of the launch of VIASKIN® Peanut Patch for children aged 4 to 7 years old in the U.S., if approved
External clinical expenses of $6.9 million, with COMFORT Toddlers study ongoing patient enrollment
Employee-related costs of $3.3 million from the addition of Quality and Regulatory resources to support BLA submission and commercial readiness activities

Selling, General and Administrative Expenses

SG&A Expenses increased by $4.6 million for the year ended December 31, 2025, compared to the year ended December 31, 2024 primarily from Market Research activities and additional roles strengthening operational capabilities towards launch of the VIASKIN® Peanut Patch for children aged 4 to 7 years in the U.S., if approved.

Net Loss

Net loss was $147.0 million for the year ended December 31, 2025, compared to $113.9 million for the year ended December 31, 2024. Net loss per share (based on the weighted average number of shares outstanding over the period) was $1.05 and $1.17 for the year ended December 31, 2025 and 2024, respectively.

Cash Position and Liquidity

On December 31, 2025, DBV held $194.2 million in cash and cash equivalents compared to $32.5 million of cash and cash equivalents on December 31, 2024.

Net cash used for operating activities was $121.2 million and $104.5 million for the years ended December 31, 2025, and 2024, respectively.

Net cash flows from financing activities totaled $276.2 million in 2025 and $0.6 million in 2024, resulting from the 2025 PIPE proceeds and the ATM facility.

Considering the supplemental gross proceeds received from completed ABSA and BS warrants exercises ($94 million) in January 2026, together with the Company's existing cash and cash equivalents as of December 31, 2025, and based on current operations, plans, and assumptions, management has determined that its cash and cash equivalents, are sufficient to fund its operations into the second quarter of 2027.

The going concern assessment is based on the Company's current forecasts and exclude any additional expenditure related to other programs than the VIASKIN® Peanut Patch or resulting from the potential in licensing or acquisition of additional product candidates or technologies, or any associated development the Company may pursue. Assumptions used in the going concern assessment may differ from actual results, and the Company may end up using its resources sooner than anticipated and seek additional resources to execute the corporate strategy either through new or existing financing strategies.

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^® 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 food allergic people. The Company's food allergy programs include ongoing clinical trials of the VIASKIN Peanut Patch 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).
