DBV Technologies Reports Full Year 2022 Financial Results and Business Update

• DBV completed EVOLVE, a 12-week caregiver and patient user experience study of the modified Viaskin Peanut patch in peanut-allergic children ages 4 – 11 years old

• DBV had $209.2 million in Cash and Cash Equivalents at December 31, 2022.

DBV Technologies (Euronext: DBV – ISIN: FR0010417345 – Nasdaq Stock Market: DBVT), a clinical-stage biopharmaceutical company, today reported financial results for the full year 2022. The audit procedures have been substantially completed by the Company’s statutory auditors and financials – prepared under both US GAAP and IFRS for the purpose of Form 10-K and Universal Registration Document respectively – were approved by the Board of Directors on March 2, 2023.

EVOLVE

DBV completed EVOLVE, a 12-week caregiver and patient user experience study of the modified Viaskin Peanut patch in 50 peanut allergic children ages 4 – 11-years old. The objective of EVOLVE was to evaluate the Instructions for Use (IFU) and ease of use for the modified Viaskin Peanut patch. The study concluded that the updated Viaskin Peanut IFU supported correct patch application, which included no lifting of the patch edges or detachment directly after application. Furthermore, EVOLVE concluded that the majority of parents/caregivers reported a positive ease of use experience with the modified Viaskin Peanut patch.

In EVOLVE, DBV also tested the functionality of an electronic patient diary (eDiary) to collect information on activities of daily living and patch adhesion scores. As previously announced, VITESSE will assess patch adhesion of the modified Viaskin Peanut patch and DBV will include a statistical test of adhesion in the VITESSE statistical analysis plan. EVOLVE verified that the eDiary tool can be used by caregivers in VITESSE to capture the adhesion data in support of a potential BLA application.

Financial Highlights for the Full Year 2022

The Company’s annual consolidated financial statements are prepared in accordance with both generally accepted accounting principles in the U.S. (“US GAAP”) and International Financial Reporting Standards (“IFRS”) as adopted by the European Union. Unless otherwise indicated, the financial figures in the Full Year 2022 Financial Highlights are presented under both U.S GAAP and IFRS financial statements, and commented using U.S. GAAP financial statements. Differences between US GAAP and IFRS consolidated financial statements are mainly due to discrepancies arising from the application of lease accounting standards.

Operating income amounts to $4,8 million as of December 31, 2022, compared to $5,7 million as of December 31, 2021, which is a decrease by $0,9 million due to:

(1) A decrease in 2022 research tax credit by $1.8 million compared to 2021. This reflects the impact of the global restructuring plan initiated in 2020 and completed in 2021 which has impacted the expenses eligible to the research tax credit.

Operating expenses amount to $101,5 million as of December 31, 2022, compared to $104,3 million as of December 31, 2021, which is a decrease by $2,8 million mainly due to the decrease in personnel expenses as a result of the global restructuring plan that was announced in 2020 and completed in the course of 2021. The average number of employees was 86 for the year ended December 31, 2022, compared to 101 and 270 for the years ended December 31, 2021 and 2020 respectively.

This reduction in our operating expenses also reflects the strict financial discipline maintained across all services to focus our resources on the support of our clinical trial objectives.
