DBV Technologies (Euronext: DBV ISIN: FR0010417345 Nasdaq Stock Market: DBVT CUSIP: 23306J200), a clinical-stage biopharmaceutical

company, today reported financial results for the third quarter of 2024. The quarterly and nine months financial statements were approved by the Board of Directors on November 6, 2024.

Financial Highlights for the third quarter Ended September 30, 2024

The Company s interim condensed consolidated financial statements for the nine months ended September 30, 2024, are prepared in accordance with

accounting principles generally accepted in the United States ( U.S. GAAP ).

Cash and Cash Equivalents

Cash and cash equivalents amounted to $46.4 million as of September 30, 2024, compared to $141.4 million as of December 31, 2023, a net

decrease of $95.0 million. This decrease includes $92.2 million in operating activities, mainly in external clinical trial related expenses, notably progress on patient enrollment in VITESSE Phase 3 clinical trial, as well as Regulatory

and Manufacturing activities to support ongoing clinical trials.

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

inception. As of the date of the filling, DBV s available cash and cash equivalents will not be sufficient to support our operating plan for at least the next 12 months. As such, there is substantial doubt regarding its ability to continue as a

Based on its current operations, plans and assumptions, the Company expects that its balance of cash and cash

equivalents will be sufficient to fund its operations into Q1 2025.

The Company intends to seek additional capital as it continues research and

development efforts and prepares for the launch of Viaskin Peanut, if approved. The Company cannot guarantee that it will be able to obtain the necessary financing to meet its needs or to obtain funds at attractive terms and conditions, including as

a result of disruptions or fluctuations of the global financial markets due to various factors outside the Company s control. A severe or prolonged economic downturn could result in a variety of risks to the Company, including reduced ability

to raise additional capital when needed or on acceptable terms, if at all.

If the Company is not successful in its financing objectives, the Company

could have to scale back its operations, notably by delaying or reducing the scope of its research and development efforts or obtain financing through arrangements with collaborators or others that may require the Company to relinquish rights to its

product candidates that the Company might otherwise seek to develop or commercialize independently.

This interim condensed financial information does 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.

Until the end of 2023, our operating income was composed of both the French Research Tax Credit scheme (Cr dit d Imp t

Recherche, or CIR ) and the revenue recognized under the Collaboration Agreement with NESTEC. Following the termination of the Collaboration Agreement on October 30, 2023, our operating income is now exclusively generated by the

French Research Tax Credit.

Operating income amounted to $3.6 million for the 9 months ended September 30, 2024, compared with

$6.9 million for the same period in 2023. This decrease by $3.2 million is composed of (1) $1.9 million following the termination of the Collaboration Agreement with NESTEC, and (2) a lower Research Tax Credit entitlement as a

greater proportion of studies activities are carried out in North America by $1.3 million

Operating expenses amounted to $96.4 million for the nine months ended September 30, 2024, compared with $71.4 million for the nine months ended

September 30, 2023, an increase by $25.0 million. This increase is primarily driven by Research & Development for $23.0 million resulting from (1) patient enrollment in VITESSE Phase 3 clinical trial,

(2) preparatory activities for the COMFORT studies in anticipation of initiation after FDA alignment, (3) Regulatory and Manufacturing activities to support ongoing clinical trials.

General and Administrative expenses increased by $1.4 million during the nine months ended

September 30, 2024, compared to the nine months ended September 30, 2023, mainly due to one-time costs associated with (1) office moves in France and the U.S., (2) financing activities and

(3) trademark and patent activities.

Net Loss and Net Loss Per Share

The Company recorded a net loss for the nine months ended September 30, 2024, of $90.9 million, compared to a net loss of $61.5 million for the

nine months ended September 30, 2023.

On a per share basis, net loss (based on the weighted average number of shares outstanding over the period) was

$(0.95) for the nine months ended September 30, 2024.
