DBV Technologies (Euronext: DBV – ISIN: FR0010417345 – Nasdaq Stock Market: DBVT), a clinical-stage biopharmaceutical company focused on treatment options for food allergies and other immunologic conditions with significant unmet medical need, today reported financial results for the first quarter 2024.

Recent Business Developments

Clinical and Regulatory Update

Enrollment for VITESSE, DBV’s Phase 3 pivotal study of the modified Viaskin Peanut patch in children ages 4 through 7 years with peanut allergy passed the halfway point for recruitment in Q1 and continues to be on track to screen the last patient by Q3 2024. VITESSE is a trial evaluating efficacy and safety in approximately 600 subjects (randomized 2:1) with 86 participating sites in US, Canada, Europe, UK and Australia.

“We are pleased with VITESSE enrollment rates and thrilled that our sites in Europe and the UK are actively enrolling subjects and have increased the momentum for VITESSE,” said Pharis Mohideen, M.D. Chief Medical Officer at DBV Technologies. “This comes on the heels of the February AAAAI meeting where there was tremendous interest in Viaskin Peanut and standing room only, record breaking attendance at our product theatre “Importance of Early Intervention for Peanut Allergy.”

The Company submitted the protocol for its COMFORT Toddlers supplemental safety study in 1 through 3-year-olds to the FDA on November 9, 2023. The Company and the FDA are engaged in ongoing dialogue related to the program.

Appointment of Robert Pietrusko, Chief Regulatory Officer

DBV has strengthened its regulatory expertise by appointing Robert Pietrusko, PharmD, to the position of Chief Regulatory Officer. Bob brings a wealth of expertise

to DBV through his more than four decades of biopharmaceutical regulatory experience.

Bob joins DBV from Vor Bio, where he has served as Chief Regulatory Officer since April 2020. He previously served as Senior Vice President of Regulatory Affairs & Quality Assurance at Voyager Therapeutics, Inc., and as Vice President of Global Regulatory Affairs and Quality at ViroPharma Incorporated (acquired by Shire in 2013). He has served in regulatory and quality assurance roles of increasing responsibility at Millennium Pharmaceuticals (acquired by Takeda in 2008) and SmithKline Beecham (part of GlaxoSmithKline).

Bob has led the regulatory effort leading to more than 35 BLA/NDA/MAA approvals globally including in the US across many FDA Divisions at both the Center for Biologics Evaluation and Research (CBER) and the Center for Drug Evaluation and Research (CDER). He is also a leader in regulatory policy through his involvement as Chair of the Regulatory Affairs Committee of the Alliance for Regenerative Medicine (ARM) and an appointed member of the Regulatory Affairs committee of the American Society of Gene and Cell Therapies (ASGCT).

“Bob brings to DBV extensive regulatory affairs and quality expertise, and his leadership is an important addition to the company,” stated Daniel Tassé, Chief Executive Officer of DBV Technologies. “In addition to his deep understanding of complex development programs, he has a proven track record of shepherding multiple products through the regulatory process to approval across the various divisions of the FDA. Bob’s guidance will be instrumental as we continue the development of Viaskin Peanut in toddlers and children. We are thrilled to welcome him to our team.”

Financial Highlights for the First Quarter Ended March 31, 2024

The Company’s interim condensed consolidated financial statements for the three months ended March 31, 2024, are prepared in accordance with accounting principles in the U.S. (“U.S. GAAP”).

Cash and Cash Equivalents

Cash and cash equivalents amount to $101,5 million as of March 31, 2024, compared to $141,4 million as of December 31, 2023, a net decrease by $39,8 million including $34,7 million of net cash flow used in operating activities, mainly external clinical-related expenses explained by progress on patient enrollment in VITESSE Phase 3 clinical trial.

The Company has incurred operating losses and negative cash flows from operations since inception. As of the date of the filing, the Company’s available cash and cash equivalents are not projected to be sufficient to support its operating plan for at least the next 12 months. As such, there is substantial doubt regarding the Company’s ability to continue as a going concern.

Based on our current operations, as well as our plans and assumptions, we expect that our balance of cash and cash equivalents of $101.5 million as of March 31, 2024, will be sufficient to fund our operations until December 31, 2024. The Company intends to seek additional capital as it continues research and development efforts and prepares for the launch of Viaskin Peanut, if approved.

Operating Income

Operating income amounts to $1,4 million for the first 3 months ended March 31, 2024, compared with $2,2 million for the same period in 2023, a decrease by $0,8 million mainly resulting from the contract termination with Nestlé Health Science for $0,4 million.

Operating Expenses

Operating expenses amount to $30 million in the first quarter, compared with $23,4 million at March 31, 2023, an increase of $6,6 million mainly due to the increase in research and development activities in particular VITESSE Phase 3 clinical trial.

Net Loss and Net Loss Per Share

Net result for the first three months ended March 31, 2024, is a loss amounting to $27,3 million, compared to a loss amounting to $20,6 million for the first three months ended March 31, 2023.

On a per share basis, net loss (based on the weighted average number of shares outstanding over the period) is $0,28 for the first 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 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 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 Montrouge, 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-half of one ordinary share) are traded on the Nasdaq Global Select Market (Ticker: DBVT).
