DBV Technologies Announces Topline Financial Results

January 29th, 2015 - DBV Technologies, (Euronext: DBV ISIN: FR0010417345 Nasdaq Stock Market: DBVT), a clinical-stage specialty biopharmaceutical company, announced today its

topline financial results, as well as its cash and cash equivalents, for full year 2014.

David Schilansky, Chief Operating Officer,

commented: The successful $133 million global offering conducted in October, in the context of our IPO on Nasdaq, allows us to step into 2015 in the best possible conditions, and notably anticipate commercial development in the US, while

ensuring timely execution of clinical development and regulatory pathway.

Topline Financial Results for Full Year 2014

For the full year 2014, our total income reached 4.8 million, up from 3.8 million for the same period in 2013. This increase primarily

resulted from an increase in Research Tax Credit amounting to 4.3 million over the period, compared to 3.3 million a year earlier. This progression stemmed from the research and development activities conducted by DBV, both on

the pre-clinical research and clinical development fronts. Sales of Diallertest amounted to 210,759 in 2014, as compared with 181,800 a year earlier.

Cash and cash equivalents at 31 December 2014

31 December 2014, DBV s cash and cash equivalents amounted to 114.5 million, as compared with 21.3 million as of 30 September, 2014 and 39.4 million as of 31 December, 2013, primarily due to the

global offering conducted in October 2014, for which the net proceeds amounted to 93.7 million.

Number of outstanding shares and dilution at

As of 31 December 2014, the number of outstanding shares was 19,160,661 ordinary shares, compared with 15,088,298 ordinary

shares a year earlier. As of 31 December 2014, the total number of ordinary shares issuable upon full exercise or definitive acquisition of all of the securities giving access to capital was 2,207,530, or a maximum dilution of 10.33% on the

basis of the fully diluted capital and voting rights, compared with 3,064,567 and 16.88% a year earlier.

About DBV Technologies

DBV Technologies is developing Viaskin , an innovative new approach to the treatment of allergies

a major public health issue that has been increasing in prevalence. DBV Technologies, incorporated in France in 2002, has developed a proprietary, worldwide-patented technology for administering an allergen to intact skin while avoiding

transfer to the blood, and thus considerably lowering the risk of a systemic, allergic reaction in the event of accidental exposure. DBV Technologies is focusing on food allergies, including milk and peanut, for which there are currently no

effective treatments. DBV Technologies has designed two products candidates: Viaskin Peanut and Viaskin Milk. The clinical

development program for Viaskin Peanut has received Fast Track designation from the US Food and Drug Administration.
