NOTES TO THE INTERIM CONDENSED FINANCIAL STATEMENTS

Note 1: The Company

Incorporated in 2002 under the laws of France, DBV Technologies S.A. ("DBV Technologies," or the "Company") is a clinical-stage specialty biopharmaceutical company focused on changing the field of immunotherapy by developing a novel technology platform called Viaskin®. The Company's therapeutic approach is based on epicutaneous immunotherapy, or EPIT®, a proprietary method of delivering biologically active compounds to the immune system through intact skin using Viaskin®.

ViaskinTM Peanut

The Company's lead product candidate, ViaskinTM Peanut, has completed a global Phase III program for the treatment of peanut-allergic patients 4 to 11 years of age. In October 2018, the Company announced its submission of a Biologics License Application ("BLA") to the U.S. Food and Drug Administration ("FDA") for ViaskinTM Peanut for the treatment of peanut allergy in children 4 to 11 years of age. On December 19, 2018, the Company announced that, after discussions with the FDA, the Company voluntarily withdrew its Biologics License Application ("BLA") for ViaskinTM Peanut in children 4 to 11 years of age. On August 7, 2019, the Company announced the submission of its BLA to the FDA for its investigational ViaskinTM Peanut immunotherapy for the treatment of peanut-allergic children ages 4 to 11 years. On October 4, 2019, the Company announced that the FDA has accepted the BLA for review. On March 16, 2020, the Company announced that the FDA had informed the Company that during the FDA's ongoing review of the BLA, it had identified questions regarding efficacy, including the impact of patch-site adhesion. Therefore, the FDA communicated that the Advisory Committee meeting to discuss the BLA would no longer take place as previously scheduled on May 15, 2020. The Company promptly submitted additional data analyses that DBV believes addressed the questions put forward by the FDA and asked the FDA to provide feedback on the path forward. These data analyses, which showed that the majority of patients treated with ViaskinTM Peanut achieved sufficient daily application duration to experience clinical benefit, have also been published in two peer-reviewed publications. Following submission of the data analyses in April and requests for discussion, FDA did not provide further information beyond that the data was being reviewed and the target action date of August 5, 2020 remains unchanged.

On January 8, 2020, the Company announced positive topline results of the three-year,open-label extension of the Phase III PEPITES trial (PEOPLE) evaluating the long-term efficacy and safety of investigational Viaskin™ Peanut in peanut-allergic children ages 4 to 11 years. The results demonstrate long-term clinical benefit as shown by an increase in eliciting dose (ED), which may decrease the chance of reacting to an accidental peanut exposure. After three years, 75.9% (107/141) of patients had increased their ED from baseline, and 51.8% (73/141) of patients reached an ED of at least 1,000 mg peanut protein by year three. The safety profile of ViaskinTM Peanut was consistent with that observed in the clinical program to date in over 1,000 patients. During PEOPLE, the most common adverse events were mild to moderate skin reactions localized to the administration site and there was no epinephrine use deemed related to treatment. Low discontinuations due to adverse events were observed in the trial. On July 10, 2020, the PEOPLE data were published online in The Journal of Allergy and Clinical Immunology (JACI).

In August 2017, the Company initiated Part A of the EPITOPE (EPIT® in Toddlers with Peanut Allergy) trial, a Phase III trial of ViaskinTM Peanut in peanut-allergic toddlers ages one to three. EPITOPE is a two- part, pivotal Phase III clinical trial assessing the safety and efficacy of ViaskinTM Peanut 250 μg for the treatment of peanut-allergic toddlers one to three years of age. In September 2018, the Company announced that the independent data safety and monitoring board ("DSMB") completed its review of Part A of EPITOPE and recommended that the dose of ViaskinTM Peanut 250 μg be evaluated in Part B. On October 26, 2018, the Company announced that the first patient was enrolled in Part B of

6

EPITOPE. This trial is the second Phase III clinical program currently investigating the use of ViaskinTM Peanut for the treatment of patients with peanut allergy. On June 26, 2020, the Company announced that in Part A, patients in both treatment arms showed consistent treatment effect after 12 months of therapy, as assessed by a double-blind placebo- controlled food challenge and biomarker results. Part A subjects were not included in Part B and the efficacy analyses from Part A were not statistically powered to demonstrate superiority of either dose versus placebo. These results validate the ongoing investigation of the 250 µg dose in this age group, which is the dose being studied in Part B of the study.

ViaskinTM Milk

The Company is developing its second product candidate, ViaskinTM Milk, for the treatment of cow's milk protein allergy ("CMPA"), in children two to 17 years of age, which received fast track designation from the FDA in September 2016. In November 2014, the Company initiated a multi-center, double- blind, placebo-controlled, randomized Phase I/II trial to study the safety and efficacy of ViaskinTM Milk in 198 patients with Immunoglobulin E ("IgE") mediated CMPA, which the Company refers to as the Milk Efficacy and Safety ("MILES") trial. In June 2015, the Company announced completion of Part A of the MILES trial, or Phase I, and it launched Part B, or Phase II, in October 2015. In February 2018, the Company announced preliminary results from Part B of the MILES trial. Following analyses of the data, the 300 μg dose was identified as the dose with the greatest observed clinical activity for children (intent-to-treat, p=0.042). All patients in the open-label extension trial were switched to the 300 μg dose for treatment of up to 24 months. Following the Company's announcement on June 26, 2020, DBV plans to focus on ViaskinTM Peanut and scale down other clinical programs and pre-clinical spend until DBV has clarity on the path forward with respect to the BLA for ViaskinTM Peanut.

ViaskinTM Egg

The Company is also working on a third product candidate, ViaskinTM Egg, for the treatment of patients suffering from hen's egg allergy. Preclinical development for ViaskinTM Egg commenced in the first half of 2015. Following the Company's announcement on June 26, 2020, DBV plans to focus on ViaskinTM Peanut and scale down other clinical programs and pre-clinical spend until DBV has clarity on the path forward with respect to the BLA for ViaskinTM Peanut.

Other ViaskinTM application

In addition to the Company's development programs in food allergies, it is exploring the use of its ViaskinTM technology for the treatment of inflammatory and autoimmune diseases with high unmet medical need. Human proof-of-concept trials with ViaskinTM in Eosinophilic Esophagitis ("EoE") and as a booster vaccination against Bordetella pertussis (whooping cough) in healthy adults have been completed. The Company's other earlier stage research programs include vaccination for respiratory syncytial virus, as well as potential treatments for celiac disease and type I diabetes. Following the Company's announcement on June 26, 2020, DBV plans to focus on ViaskinTM Peanut and scale down other clinical programs and pre-clinical spend until DBV has clarity on the path forward with respect to the BLA for ViaskinTM Peanut.

Major events during the first half of 2020

1. CONSEQUENCES OF THE COVID-19PANDEMIC

The recent outbreak of the novel coronavirus COVID-19, which was declared a pandemic by the World Health Organization on March 11, 2020, has led to adverse impacts on the global economies, disruptions of financial markets, and created uncertainty regarding potential impacts to the Company's operations including approval of ViaskinTM Peanut, our clinical trials, as well as on our clinical trial material distribution system.

7

In response to the COVID-19 pandemic, on March 10, 2020, the FDA announced the postponement of most inspections of foreign manufacturing facilities and prior approval inspections (PAI). If this situation were to continue and prevent the FDA from conducting its inspections at the Company's contractors' sites, it could have a significant impact on the FDA's ability to review and process the Company's regulatory submissions in a timely manner.

The current clinical trials (including Phase III EPITOPE, EPOPEX, REALISE, PEOPLE) and future clinical trials that the Company is conducting in the United States, Australia and in Europe have been and may continue to be affected by the COVID-19 epidemic. The Company has experienced a decrease in new patients enrolling in the ongoing clinical studies and it has had to adapt the protocols of its clinical trials because patients remain subject to travel restrictions. The Company has developed direct-to-patient shipment of clinical trial materials in Europe and the United States to allow for an uninterrupted supply of clinical trial patients. Apart from this change in the distribution model, there have been no disruptions in the supply chain for conducting clinical trials and the Company believes that it will be able to meet the clinical material needs of its ongoing clinical studies.

Due to containment measures taken in France, the Company's French subcontractors slowed down their activity from March 2020 to May 2020 and some implemented Business Continuity Plans. However, manufacturing facilities remained operational and the Company believes that this pandemic will have a limited impact on the short- and medium-term production of patches for clinical trials, as well as on the launch of ViaskinTM Peanut, if approved.

Furthermore, the Company is closely monitoring the progress of COVID-19 and its potential impact on the organization. In accordance with public health directives aimed at slowing the spread of COVID-19, the Company has implemented, starting in mid-March 2020, a distance-work plan for all employees. The Company supports all employees by taking advantage of virtual meeting technology and encourages employees to follow the guidelines of local health authorities.

In accordance with the French government measures taken as part of the COVID-19 epidemic, the company has set-up partial activity for certain employees for the months of April and May 2020 and deferred payment of social security contributions. In addition, Bpifrance suspended all repayment, as of March 24, 2020 and for a period of 6 months. Therefore, no reimbursements were made in the first half of 2020.

As of the date of our report, the Company cannot measure the extent, duration or total impact that the COVID-19 pandemic will have on its financial condition and operations. The impact of the COVID-19 pandemic on the Company's financial results will depend on future developments, including the duration and spread of the COVID-19 pandemic and related governmental notices and restrictions. These developments and the impact of COVID-19 on the financial markets and the economy in general are also highly uncertain and the Company may experience adverse impacts to its business as a result of any economic recession or depression that has occurred or may occur in the future..

2. CLINICAL PROGRAMS

ViaskinTM Peanut

On January 8, 2020, the Company announced positive topline results of the three-year,open-label extension of the Phase III PEPITES trial (PEOPLE) evaluating the long-term efficacy and safety of investigational Viaskin™ Peanut in peanut-allergic children ages 4 to 11 years. The results demonstrate long-term clinical benefit as shown by an increase in eliciting dose (ED), which may decrease the chance of reacting to an accidental peanut exposure. After three years, 75.9% (107/141) of patients had increased their ED from baseline, and 51.8% (73/141) of patients reached an ED of at least 1,000 mg

8

peanut protein by year three. The safety profile of ViaskinTM Peanut was consistent with that observed in the clinical program to date in over 1,000 patients. During PEOPLE, the most common adverse events were mild to moderate skin reactions localized to the administration site and there was no epinephrine use deemed related to treatment. Low discontinuations due to adverse events were observed in the trial.

On February 21, 2020, the Company announced an allergenic products advisory committee meeting from the FDA to be held on May 15, 2020 to discuss the BLA for Viaskin™ Peanut. On March 16, 2020, the Company announced that the FDA had informed the Company that during the FDA's ongoing review of the BLA, it had identified questions regarding efficacy, including the impact of patch-site adhesion. Therefore, the Advisory Committee meeting to discuss the BLA would no longer take place as previously scheduled on May 15, 2020. The Company promptly submitted additional data analyses that DBV believes addressed the questions put forward by the FDA and asked the FDA to provide feedback on the path forward. These data analyses, which showed that the majority of patients treated with ViaskinTM Peanut achieved sufficient daily application duration to experience clinical benefit, have also been published in two peer-reviewed publications in June 2020. Following submission of the data analyses in April and requests for discussion, FDA did not provide further information beyond that the data was being reviewed and the target action date of August 5, 2020 remains unchanged.

On June 26, 2020, the Company announced that in Part A of EPITOPE, patients in both treatment arms showed consistent treatment effect after 12 months of therapy, as assessed by a double-blind placebo- controlled food challenge and biomarker results. Part A subjects were not included in Part B and the efficacy analyses from Part A were not statistically powered to demonstrate superiority of either dose versus placebo. These results validate the ongoing investigation of the 250 µg dose in this age group, which is the dose being studied in Part B of the study.

3. CHANGE IN THE GROUP'S ORGANIZATION

On January 2, 2020, the Company announced the appointment of Ramzi Benamar as its Chief Financial Officer. He serves as a member of the Executive Committee and reports to Daniel Tassé, Chief Executive Officer of DBV Technologies.

On January 9, 2020, Marie-Catherine Therene was appointed Deputy CEO as DBV's responsible pharmacist (Pharmacien Responsable) in accordance with applicable regulations in France.

On February 6, 2020, the Company announced the appointment of Pascal Wotling as its Chief Technical Operations Officer (CTOO), effective April 1, 2020. Pascal is responsible for manufacturing, supply chain and new product process development, and serves as a member of the Executive Committee, reporting to Daniel Tassé.

On June 26, 2020, the Company announced that given it has not yet received an update from the U.S. FDA regarding its BLA for ViaskinTM Peanut, it has undergone a comprehensive business review to best position DBV for the possibility of a delay in timelines for the ViaskinTM Peanut BLA review. As a result, the Board of Directors has approved the immediate initiation of a global and comprehensive restructuring plan, which is expected to include a significant reduction in workforce. The Company has initiated, in compliance with French law, the mandatory consultation process with DBV's Social and Economic Committee in France. The Company announced it is contemplating the implementation of cost reduction measures across the organization, while preserving core activities and competencies. Given the absence of clarity from the FDA, DBV is implementing a restructuring plan that will provide the flexibility to continue the BLA review process, prepare to bring ViaskinTM Peanut to patients, if approved, and preserve the Company's cash runway.

4. FINANCING

On February 4, 2020, the Company announced the closing of an underwritten global offering of an aggregate of 7,500,000 ordinary shares in (i) a public offering of 4,535,581 ordinary shares in the form of 9,071,162 American Depositary Shares ("ADSs") in the United States, Canada and certain countries outside Europe at a public offering price of $10.25 per ADS (on the basis of an exchange rate of $1.0999

  • €1.00), and (ii) an offering exclusively addressed to qualified investors in Europe (including France) of 2,964,419 ordinary shares at an offering price of €18.63 per ordinary share (together, the "Global Offering").

On March 2, 2020, the Company announced that the underwriters partially exercised their option to purchase 338,687 additional ordinary shares in the form of 677,374 ADSs at an offering price of $10.25 per ADS, before deducting commissions and estimated offering expenses (the "Option"). The Option closed on March 4, 2020.

Consequently, following partial exercise of the Option, the total number of ordinary shares sold in the global offering was 7,838,687 ordinary shares, including 4,874,268 ordinary shares in the form of 9,748,536 ADSs, bringing the total gross proceeds from the global offering to approximately $160.7 million (approximately €146.1 million) and net proceeds of €136.6 million.

5. OTHER KEY EVENTS

Legal Proceedings

A class action complaint was filed on January 15, 2019 in the United States District Court for the District of New Jersey, entitled Travis Ito-Stone v. DBV Technologies, et al., Case No. 2:19-cv-00525. The complaint alleged that the Company and its former Chief Executive Officer, its current Chief Executive Officer, and its Deputy Chief Executive Officer violated certain federal securities laws, specifically under Sections 10(b) and 20(a) of the Exchange Act, and Rule 10b-5 promulgated thereunder. The plaintiffs seek unspecified damages on behalf of a purported class of purchasers of our securities between February 14, 2018 and December 19, 2018.

Subsequently, lead plaintiffs were appointed and an amended complaint was filed on January 24, 2020, adding the Company's former Chief Business Officer as a defendant. In March 2020, the Company announced that the FDA identified questions regarding efficacy, including the impact of patch-site adhesion. Following this announcement, the plaintiffs filed an amended complaint on June 12, 2020, adding allegations related to the March 2020 announcement and expanding the class period, from February 14, 2018 to March 16, 2020. The Company believes that the allegations contained in the amended complaint are without merit and intend to defend the case vigorously.

1. SCOPE OF CONSOLIDATION

As of June 30, 2020, the scope of consolidation is composed of 5 entities, a parent company DBV Technologies SA, a Corporate French venture under French law (société anonyme) and has its registered offices located at 177/181 avenue Pierre Brossolette, 92120 Montrouge (France) and its four subsidiaries :

  • DBV Technologies Inc. was incorporated in Delaware on April 7, 2014 (the "US subsidiary").
  • DBV Australia Pty Ltd. was incorporated in New South Wales, Australia on July 3, 2018 (the
    "Australian subsidiary").
  • DBV Canada Ltd. was incorporated in Ottawa, Ontario on August 13, 2018 (the "Canadian subsidiary").
  • DBV Pharma was incorporated in Paris on December 21, 2018 (the "French subsidiary").

The share capital of each of the subsidiaries is wholly owned by DBV Technologies S.A. ("DBV Technologies") and they are fully consolidated using the full consolidation method.

2. GENERAL PRINCIPLES

The interim consolidated condensed financial statements (the "Financial Statements") present the operations of DBV Technologies S.A. and its subsidiaries (the "Group") as of June 30, 2020. DBV Technologies is a Corporate French venture under French law (société anonyme) and has its registered offices located at 177/181 avenue Pierre Brossolette, 92120 Montrouge (France).

The interim condensed consolidated financial statements at June 30, 2020 have been prepared under the responsibility of the management of DBV Technologies. These interim condensed financial statements were approved by the Board of Directors of the Company on July 30, 2020.

The interim condensed consolidated financial statements of the Group are expressed in thousands of euros unless stated otherwise.

3. STATEMENT OF COMPLIANCE

International accounting standards include International Financial Reporting Standards (IFRS), International Accounting Standards (IAS), as well as the interpretations issued by the Standing Interpretations Committee (SIC), and the International Financial Reporting Interpretations Committee (IFRIC).

The IFRS as adopted by the European Union differ in certain aspects with the IFRS published by the IASB. Nevertheless, the Group ensured that the financial information for the periods presented would not have been substantially different if it had applied IFRS as published by the IASB.

All text adopted by the European Union are available on the European Commission's website: https://www.efrag.org/Endorsement

The interim consolidated condensed financial statements at June 30, 2020 were prepared in accordance with IAS34 -Interim Financial Reporting, as endorsed by the European Union, which requires the disclosure of selected explanatory notes only.

The condensed financial statements do not include all disclosures required for annual financial statements and should therefore be read in conjunction with the consolidated financial statements for the year ended December 31, 2019.

11

Note 3: Accounting principles and methods used at June 30, 2020

These condensed consolidated financial statements are prepared using the same accounting policies and methods as those applied by DBV Technologies at December 31, 2019 (described in Note 3 of the consolidated accounts as of December 31, 2019 published) and in accordance with other standards and interpretations that came into effect on January 1, 2020.

The Company did not elect for early application of the new standards, amendments and interpretations which were adopted by European Union but not mandatory as of January 1, 2020:

  • IFRS 17 - Insurance contracts;
  • Amendments to IFRS 3 - Definition of a business;
  • Amendments to References to the Conceptual Framework in IFRS Standards.

Management is in the process of evaluating the impact of these standards and amendments application.

3.1. Going concern

Since its inception, the Company has primarily funded its operations with equity financings, and, to a lesser extent, public assistance aimed at supporting innovation as well as payments associated with research tax credit (Crédit d'Impôt Recherche). The Company does not generate product revenue and continues to prepare for the potential launch of its first product in the United States, if approved.

Following the Company's submission of data analyses in April 2020 and requests, FDA did not provide further information beyond that the data was being reviewed and the target action date of August 5, 2020 remained unchanged. Given the absence of clarity from the FDA, DBV announced on June 26, 2020 that it was implementing a restructuring plan that would allow the Company to continue the BLA review process, prepare to launch ViaskinTM Peanut, if approved, while preserving the Company's cash.

In October 2019, the Company announced the FDA's acceptance of its Biologics License Application ("BLA") for ViaskinTM Peanut, with a target action date of August 5, 2020. On March 16, 2020, a press release was issued to announce that the FDA had informed the Company that during the FDA's ongoing review of the BLA, it had identified questions regarding efficacy, including the impact of patch- site adhesion. Therefore, the FDA communicated that the Advisory Committee meeting to discuss the BLA would no longer take place as previously scheduled on May 15, 2020. The Company promptly submitted additional data analyses that DBV believes addressed the questions put forward by the FDA and asked the FDA to provide feedback on the path forward. These data analyses, which showed that the majority of patients treated with ViaskinTM Peanut achieved sufficient daily application duration to experience clinical benefit, have also been published in two peer-reviewed publications.

DBV plans to focus on ViaskinTM Peanut and scale down other clinical programs and pre-clinical spend. The Company is contemplating the implementation of cost reduction measures across the organization, while preserving core activities and competencies. The revised plan and proposed cost structure assume that ViaskinTM Peanut will not be launched in the United States within the next 12 months and that the restructuring plan initiated in France will be approved by the French authorities within the planned deadlines. On this basis, DBV now expects that its current balance of cash and cash equivalents of €225.9 million as of June 30, 2020 will be sufficient to fund its operations significantly beyond the prior guidance of the first quarter of 2021 and to support the Company's operating plan for at least the next 12 months. Following feedback from FDA on the ViaskinTM Peanut BLA review, the Company will provide updated financial guidance.

The Company plans to continue to seek additional capital as it prepares for the launch of ViaskinTM Peanut, if approved, and continues the research and development efforts for other product candidates

12

using its ViaskinTM Platform. The Company may seek to finance its future cash needs through a combination of public or private equity or debt financings, collaborations, license and development agreements and other forms of non-dilutive financings. Considering the situation of the financial markets following the COVID-19 pandemic, 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. The ongoing global financial crisis caused by the COVID-19 pandemic has already caused extreme volatility and disruptions in the capital and credit markets. 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 and on acceptable terms, if at all.

The Company's interim financial statements have been prepared on a going concern basis as of June

30th, 2020. Consequently, no adjustments have been made to the financial statements relating to the recoverability and classification of the asset carrying amounts or classification of liabilities that might be necessary should we not be able to continue as a going concern.

Refer to the liquidity risk disclosed in the section 4 - Risks factors of the half year 2020 financial report.

3.2. Use of Estimates

The preparation of the Company's Financial Statements requires the management to make estimates,

assumptions and judgments that affect the reported amounts of assets, liabilities, revenue and expenses. Estimates and assumptions are based on historical experience and other factors that management believes to be reasonable under the circumstances. Estimates and assumptions are measured on an ongoing basis. Actual results may differ from these estimates.

These estimates and judgments mainly involve:

  • an estimate of the costs linked with the restructuring plan announced on June 30, 2020, based on the management's best estimate of related social costs, lawyers and consulting fees, or contract termination costs;
  • the expected dates of achievement of any performance conditions used to estimate the duration of the spillover from the granting of stock options and free shares;
  • the estimate of provision for depreciation of current assets, in particular inventories' work in progress;
  • an estimate of the Research Tax Credit based on internal and external expenses incurred by the Company during the period. Only eligible research expenses are included in the calculation of the research tax credit;
  • an estimate of time and costs required to complete the collaboration agreement with Nestlé Health Science;
  • other employee related accruals such as bonus accruals.

At the date of this report, the Company does not intend to close any facilities in France and in its subsidiaries. As a result, the Company did not identify any asset that may be impaired including lease contracts, laboratory equipment, leasehold improvements, office and computer equipment.

Note 10: Financial liabilities

As of June 30, 2020, the Company had a grant from BpiFrance. In 2014, BpiFrance Financement granted an interest-free Innovation loan of €3,000,000 to DBV Technologies to help finance the pharmaceutical development of Viaskin™ Milk. This amount was received in a single disbursement on November 27, 2014. The planned repayment is scheduled in 20 quarterly repayments of €150,000 each, starting on June 30, 2017. As of March 2, 2020, due to the COVID-19 pandemic, Bpifrance has suspended the repayment for a 6 month period. As a result, the Company did not make any repayments in the first half of 2020.

A conditional advance of €1.8 million, granted in 2013 by OSEO to the Company as part of a collaborative research and clinical development in mite allergy for young children has been fully repaid in 2019.

Note 15: Restructuring costs

On June 26, 2020, the Company's Board of Directors approved a restructuring to further extend the Company's operating capital and align personnel towards the possibility of a delay in timelines for the ViaskinTM Peanut BLA review. As of June 30, 2020, the Company initiated a significant reduction of its workforce in U.S. and intends to reduce its workforce in France under the restructuring plan. The Company has initiated, in compliance with French law, the mandatory consultation process with DBV's Social and Economic Committee in France.

The Company estimates that it will incur aggregate charges of approximately €19.3 million based on the management best estimates and including the following costs :

  • Employee related expenses including legal and supra-legal allowances, benefits, costs for redeployment aid and accompanying measures;
  • Contract termination costs;
  • Consulting and lawyers, as well as fees related to psycho-social risks monitoring and social engineering.

The social component of the restructuring plan is expected to be substantially complete by the end of 2020.

At the date of this report, the Company does not intend to close any facilities in France and in its subsidiaries. As a result, as of June 30, 2020, the Company did not identify any asset that may be impaired including lease contracts, laboratory equipment, leasehold improvements, office and computer equipment.

Note 16: Share-based payments

The shares-based payments mainly involve stock options and free shares granted to employees and corporate officers.

The stock options granted may be exercised at any time after a vesting period of between 0 and 4 years and become null and void after a period of 10 years from the date they are granted.

The expense representing the benefit granted is recorded in the financial statements using the straight-line method as a personnel expense over the vesting period. The acquisition of free shares and

21

exercise of stock options depend on the existence of an employment contract or holding a corporate office between the recipient and the Company until expiration of the current vesting period as from their initial allocation.

For the six months ended June 30, 2020:

  • 94,500 stock options were granted to US employees with exercise prices of €14.64. Contingent upon the holders' continued employment with the Company, these stock options can be vested over a four-year vesting period, on the basis of 25% one year after the grant and 12.5% every 6 months, The exercise will be subject to the following performance condition: approval of ViaskinTM Peanut by the FDA. The options will be forfeited 10 years after their grant;
  • Free shares plans were granted to French employees for a total of 5,000 shares.
    The definitive allocation of the free shares, subject to a presence requirement, will only occur at the later of the following two dates:
    o expiry of the current vesting period as from their initial allocation and o approval of ViaskinTM Peanut by the FDA (performance condition).

The IFRS 2 Share based payment for the six months ended June 30, 2020 amounts to €2.9 million compared to €8.0 million for the six months ended June 30, 2019

As of June 30, 2020, the expenses associated with share-based compensations include an estimate related to possible requests pertaining to a select number of free share plans from employees in France.

As of June 30, 2020, the total number of ordinary shares that can be created through a full exercise or definitive acquisition, depending on the case, of all of securities giving access to the capital and instruments issued to date amounts to 2,994,173 at a weighted average exercise price of €22.70 (this weighted average exercise price does not include the 693,445 of potential shares resulting from the definitive acquisition of free shares).

Note 20: Subsequent events

On July 10, 2020, the Company announced that in Part A, patients in both treatment arms showed consistent treatment effect after 12 months of therapy, as assessed by a double-blind placebo- controlled food challenge and biomarker results. Part A subjects were not included in Part B and the efficacy analyses from Part A were not statistically powered to demonstrate superiority of either dose versus placebo. These results validate the ongoing investigation of the 250 µg dose in this age group, which is the dose being studied in Part B of the study.

The Company evaluated subsequent events that occurred after June 30 2020, through the date of approval of the condensed consolidated financial statements by the Board of Directors and determined that there are no other significant events that require adjustments or disclosure in such condensed consolidated financial statements.

II - MANAGEMENT DISCUSSION & ANALYSES

ANALYSIS OF PROFIT & LOSS STATEMENT

Operating Revenue

Our total operating revenue was €7.6 million and €7.1 million for the six months period ended June 30, 2020 and 2019, respectively. This income was mainly generated by our Research Tax Credit and by income recognized under the May 2016 collaboration agreement with Nestlé Health Science.

As R&D expenses are not capitalized until a marketing authorization is obtained, the Research Tax Credit related to such R&D programs is recorded as operating income. Grants received during the periods were deducted from the calculation of the Research Tax Credit.

For the six months ended June 30, 2020 and 2019, we recorded a Research Tax Credit for €5.3 million and €6.0 million, respectively. The decrease in revenues related to the Research Tax Credit is mainly due to the decrease in subcontracting and personnel expenses taken into account in the calculation base over the first 6 months of 2020 compared to the first 6 months of 2019.

Beginning in the fiscal year ending December 31, 2019, we will no longer benefit from the immediate reimbursement of the Research Tax Credit due to the loss of our SMEs status under EU law. The Research Tax Credit will now be refunded three years after the tax declaration in the event we cannot offset it against corporate income tax due.

For the first half 2020 and 2019, respectively, we also recorded as other income a portion of the upfront fee and milestones agreed under the contract with Nestlé Health Science, which are deferred over the service obligation period.

Operating Expenses

As of June 30 ,2020 the Company has undergone a comprehensive business review to best position DBV for the possibility of a delay in timelines for the ViaskinTM Peanut BLA given that the Company has not yet received any update from the U.S. FDA regarding its BLA for ViaskinTM Peanut.

As a result, the Board of Directors has approved the immediate initiation of a global and comprehensive restructuring plan, which is expected to include a significant reduction in workforce.

The related restructuring costs are presented in a separate line of the statement of loss as of June 30, 2020. The Company has also updated its assumptions to take into account the possibility of a delay in timelines for the ViaskinTM Peanut BLA review and the expected impacts from the announced restructuring on June 26, 2020.

Research and Development Expenses decreased by 7.5% during in the first half 2020 to €48.3 million compared with €52.2 million in the same period in 2019.

Personnel expenses related to research and development decreased by 27.4% compared to the same period in 2019, resulting from a decrease in accrued bonus, retention measures and share-based compensation expense. These decreases are linked with the anticipated changes related to the announced restructuring plan, including the impact of reduced headcount.

The average staff dedicated to Research and Development decreased in comparison to same period in 2019 (from 223 employees in the first half 2019 to 207 employees in the first half 2020). The average staff dedicated to Research and Development is not materially impacted by the restructuring announced on June 26, 2020.

The decrease of 11.5% for sub-contracting, collaborations and consultants mainly relates to expenses incurred in the first half 2019 for the preparation of the ViaskinTM Peanut BLA for submission to the FDA in August 2019.

26

Sales and Marketing Expenses decreased by 23.4% during in the first half 2020 to €6.4 million compared with €8.3 million in the same period in 2019. Sales and marketing expenses primarily include payroll for U.S. employees, as well as fees related to pre-commercialization activities for ViaskinTM Peanut in North America.

Personnel expenses related to sales and marketing decreased by 48.2% compared to the same period in 2019, resulting from a decrease in accrued bonus, retention measures and share-based compensation expense. These decreases are linked with the change in structuring assumptions used for estimates calculation and to the impacts of the expected headcount reduction related to the announced restructuring plan.

The average staff dedicated to sales and marketing increased in comparison to same period in 2019 (from 30 employees in the first half 2019 to 33 employees in the first half 2020). The average headcount is not materially impacted by the restructuring announced on June 26, 2020.

The increase in fees is mainly due to the increase of fees related to customer engagement as well as marketing tools and services incurred in the first half of 2020 for the preparation of the launch of ViaskinTM Peanut in the U.S., if approved.

General and Administration Expenses were €19.4 million in the first half 2020, compared with €25.8 million in the first half 2019, and include mainly administrative and management personnel costs and certain fees, such as audit, legal and consultants' fees.

Personnel expenses related to General and Administrative expenses decreased by 62.4% compared to the same period in 2019, resulting from a decrease in accrued bonus, retention measures and share- based compensation expense. These decreases are linked with the change in structuring assumptions used for estimates calculation and to the impacts of the expected headcount reduction related to the announced restructuring plan.

The average staff dedicated to General and Administrative expenses increased in comparison to same period in 2019 (from 64 employees in the first half 2019 to 71 employees in the first half 2020). The average headcount is not materially impacted by the restructuring announced on June 26, 2020.

The increase in fees mainly results from the increase of consulting and lawyers' fees in the first half of 2020.

Insurance policies increased by €1.3 million and mainly relates to the increase in Directors and Officers insurance premium.

Restructuring costs were €19.3 million for the six months ended June 30, 2020.

On June 26, 2020, the Company's Board of Directors approved a restructuring to further extend the Company's operating capital and align personnel towards the possibility of a delay in timelines for the ViaskinTM Peanut BLA review. As of June 30, 2020, the Company initiated a significant reduction of its workforce in its subsidiaries mainly in U.S. and intends to reduce its workforce in France under the restructuring plan. The Company has initiated, in compliance with French law, the mandatory consultation process with DBV's Social and Economic Committee in France.

The Company estimates that it will incur aggregate charges of approximately €19.3 million based on the management best estimates and including the following costs:

  • Employee related expenses including legal and supra-legal allowances, benefits, costs for redeployment aid and accompanying measures;
  • Contract termination costs;
  • Consulting and lawyers, as well as fees related to psycho-social risks monitoring and social engineering.

The social component of the restructuring plan is expected to be substantially complete by the end of 2020.

At the date of this report, the Company does not intend to close any facilities in France and in its subsidiaries. As a result, the Company did not identify any asset that may be impaired including lease contracts, laboratory equipment, leasehold improvements, office and computer equipment.

The Company remains focus to preserve its core functions, extend its cash runway and maintain operating latitude to bring ViaskinTM Peanut to patients in need, if approved.

Financial (Loss) was €(0.6) million in the first half 2020, compared to a loss €(0.5) million in the same period in 2019. This item includes the financial revenues on our financial assets, foreign exchange losses, undiscounting expenses in connection with BpiFrance, and financial expenses on lease obligations.

Net (Loss) at the end of June 30, 2020 was €(86.5) million compared to €(79.8) million at the end June 30, 2019. The loss per share was €(1.62) and €(2.43) for the six months ended June 30, 2020 and 2019 respectively, based on a weighted average number of shares outstanding of 53,383,299 as of June 30, 2020 and 32,889,633 as of June 30, 2019.

ANALYSIS OF THE BALANCE SHEET

Non-currentassets were €61.7 million and €59.4 million as of June 30, 2020 and December 31, 2020, respectively, and include long-term intangible assets, rights of use relating to leases, intangible assets and non-current financial assets. The change in other non-currentassets is mainly due to the recognition of €5.3 million related to the Research Tax Credit in the six months ended June 30, 2020.

Net current assets were €237.9 million and €182.1 million as of June 30, 2020 and December 31, 2019, respectively including net cash and cash equivalents of €225.9 million as of June 30, 2020 compared to €172.0 million as of December 31, 2019. This variation results mainly from the change in the cash and cash equivalent, driven by the public offering of the first quarter 2020 with net proceeds of €136.6 million, partially offset by cash used in operating activities.

The net change in the Company's shareholders' equity mainly results from the losses realized over the period and from the public offering of the first quarter 2020. Shareholders' equity was €224.2 million as of June 30, 2020 compared to €171.6 million at December 31, 2019.

Current and non-currentliabilities were €75.4 million and €69.9 million as of June 30, 2020 and December 31, 2019, respectively. This change resulted primarily from the recognition of a restructuring actuals and accruals for €19.3 million partially offset by the decrease in other personnel related accruals (including bonus).

IV - RISK FACTORS

Since it was first identified in China in December 2019, a novel strain of coronavirus disease (COVID-19) has spread globally, resulting in the declaration of a pandemic by the World Health Organization (WHO) on March 11, 2020. To limit this spread, multiple restrictive measures have been imposed in many countries: quarantines, bans on large public gatherings, closure of places open to the public, restrictions or even bans on movement and the containment of a large part of the world's population. In this context of health crisis caused by the pandemic, the Company has updated some risk factors presented in the 2019 Universal Registration Document. The other main risks that the Company may face in the remaining six months of the financial year are the same to those presented in section 1.4 of the 2019 universal registration document filed with the Autorité des Marchés Financiers ("AMF") on March 20, 2020 (AMF number D.20-0153). All of these risks are likely to occur during the remaining six months of the financial year.

The following risk factors should be read in conjunction with, and are qualified in all respects by, those appearing under the heading "Risk Factors" in our Annual Report on Form 20-F for the year ended December 31, 2019 filed with the Securities and Exchange Commission ("SEC") on March 20, 2020 (the "Annual Report").

1. LIQUIDITY RISK REFLECTING ITS ABILITY TO CONTINUE AS A GOING CONCERN

On June 30, 2020, the Company had €225.9 million in cash and cash equivalents compared to €172.0 million of cash and cash equivalents on December 31, 2019. The Company has incurred operating losses and negative cash flows from operations since its inception. Net cash used in operating activities was €79.4 and €77.2 million for the first half 2020 and the first half 2019, respectively. As of June 30, 2020, the Company recorded a net loss of €86.5 million.

Since its inception, the Company has primarily funded its operations with equity financings, and, to a lesser extent, public assistance aimed at supporting innovation as well as payments associated with research tax credit (Crédit Impôt Recherche). The Company does not generate product revenue and continues to prepare for the potential launch of its first product in the United States, if approved.

In October 2019, the Company announced the FDA's acceptance of its Biologics License Application ("BLA") filing for ViaskinTM Peanut, with a target action date of August 5, 2020. On March 16, 2020, a press release was issued to announce that the FDA had informed the Company that during the FDA's ongoing review of the BLA, it had identified questions regarding efficacy, including the impact of patch- site adhesion. Therefore, the FDA communicated that the Advisory Committee meeting to discuss the BLA would no longer take place as previously scheduled on May 15, 2020. The Company promptly submitted additional data analyses that DBV believes addressed the questions put forward by the FDA and asked the FDA to provide feedback on the path forward. These data analyses, which showed that the majority of patients treated with ViaskinTM Peanut achieved sufficient daily application duration to experience clinical benefit, have also been published in two peer-reviewed publications.

Following the Company's submission of data analyses in April 2020 and requests for discussion, FDA did not provide further information beyond that the data was being reviewed and the target action date of August 5, 2020 remained unchanged. Given the absence of clarity from the FDA, DBV announced on June 26, 2020 that it was implementing a restructuring plan that would provide the Company the flexibility to continue the BLA review process, prepare to launch ViaskinTM Peanut, if approved, while preserving the Company's cash.

DBV plans to focus on ViaskinTM Peanut and scale down other clinical programs and pre-clinical spend. The Company is contemplating the implementation of cost reduction measures across the organization, while preserving core activities and competencies. The revised plan and proposed cost structure assume that ViaskinTM Peanut will not be launched in the United States within the next 12

31

months and that the restructuring plan initiated in France will be approved by the French authorities within planned deadlines. On this basis, DBV now expects that its current balance of cash and cash equivalents of €225.9 million as of June 30, 2020 will be sufficient to fund its operations significantly beyond the prior guidance of the first quarter of 2021 and to support the Company's operating plan for at least the next 12 months. Following feedback from FDA on the ViaskinTM Peanut BLA review, the Company will provide updated financial guidance.

The Company plans to continue to seek additional capital as it prepares for the launch of ViaskinTM Peanut, if approved, and seeks to continue the research and development efforts for other product candidates using its ViaskinTM Platform. The Company may seek to finance its future cash needs through a combination of public or private equity or debt financings, collaborations, license and development agreements and other forms of non-dilutive financings. 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. The ongoing COVID-19 pandemic has already caused extreme volatility and disruptions in the global capital and credit markets. A severe or prolonged economic downturn could result in a variety of risks to the Company, including reduced ability to raise additional capital on acceptable terms when needed, if at all.

The Company's interim financial statements have been prepared on a going concern basis as of June 30, 2020. Consequently, no adjustments have been made to the financial statements relating to the recoverability and classification of the asset carrying amounts or classification of liabilities that might be necessary should we not be able to continue as a going concern.

2. VOLATILITY RISK

The market price of the Company's securities could continue to be subject to significant fluctuations. Market prices for securities of early-stage pharmaceutical, biotechnology and other life sciences companies have historically been particularly volatile. Some of the factors that may cause the market price of the Company's securities to fluctuate include:

  • The results of the Company's preclinical studies and clinical trials or those of its competitors ;
  • A potential delay or refusal by the FDA in the United States (or equivalent in another country) to obtain BLA (or equivalent) approval for ViaskinTM Peanut.
  • Evidence of the safety and efficacy of the Company's products and/or those of its competitors;
  • Regulatory decisions, in particular those governing the pharmaceutical industry or the food allergy field;
  • Changes in the outlook for the Company or its competitors from one period to the next;
  • Announcement by the Company or its competitors, of technological innovations or the commercialization of new products;
  • Development by the Company or its competitors of initiatives involving partner companies;
  • Developments concerning the Company's or its competitors' patents or intellectual property rights, including litigation;
  • Announcements of changes to the Company's shareholders;
  • Announcements of changes to the Company's management team.

For example, the Company's announcement on October 20, 2017, that it had not reached the minimum confidence interval of 15% as proposed in the Statistical Analysis Plan of its PEPITES clinical study, despite having achieved other criteria, caused its market capitalization to fall by more than 50%.

Furthermore broad market and industry factors, including potentially worsening economic conditions and other adverse effects or developments related to the ongoing COVID-19 pandemic, may negatively

32

affect the market price of the Company's securities, regardless of the Company's actual operating performance.

Additionally, the Company's American Depositary Shares (ADS) are listed on the Nasdaq Global Select Market and ordinary shares in the Company are listed on the Euronext Paris regulated market. Volatility and liquidity in the U.S. market may be different from the French market. The Company cannot predict the impact of its dual listing of ADS and ordinary shares. Should liquidity for shares listed on Euronext Paris not be sustained, the share price may be more volatile and it may become more difficult to buy or sell shares on the Euronext Paris market than on the Nasdaq Global Select Market. Dual listing of the Company's securities in two different currencies (euro and U.S. Dollar) opens the possibility of an arbitrage strategy between the two stock exchanges, which could adversely impact the price of the ADS and the ordinary shares. The sale of the Company's shares or the expectation of their sale may adversely impact the Company's share price. The Company cannot predict the potential impact of its shareholders selling their shares on the market price of its shares.

3. THE COMPANY IS DEPENDENT ON OBTAINING AUTHORIZATIONS PRIOR TO MARKETING ITS PRODUCTS, WHICH IS UNCERTAIN

To date, the Company does not have a drug approved for sale and it may never be able to develop a marketable drug or biopharmaceutical product. The Company's business depends almost entirely on the successful clinical development, regulatory approval, and marketing of its product candidates based on ViaskinTM technology: ViaskinTM Peanut.

On August 7, 2019, the Company announced that it had filed a Biologics License Application (BLA) with the U.S. Food and Drug Administration (FDA) for the treatment of peanut-allergic children 4 to 11 years of age, for ViaskinTM Peanut, its lead product candidate. This application incorporated additional data regarding manufacturing and quality control procedures formulated by the FDA in December 2018 in response to the Company's first BLA submission in October 2018 which it had voluntarily withdrawn after discussions with the FDA.

On October 4, 2019, the Company announced that the FDA had accepted its ViaskinTM Peanut BLA filing for review. The target action date provided by the FDA is August 5, 2020.

On February 21, 2020, the Company announced an Allergenic Products Advisory Committee (APAC) meeting to be held on May 15, 2020 to discuss the BLA for Viaskin™ Peanut.

On March 16, 2020, the Company announced that the FDA had informed the Company that during its ongoing review of the BLA for investigational Viaskin™ Peanut, it has identified questions regarding efficacy, including the impact of patch-site adhesion. Therefore, the APAC meeting to discuss the BLA would no longer take place as previously scheduled on May 15, 2020. The Company promptly submitted additional data analyses that DBV believes addressed the questions put forward by the FDA and asked the FDA to provide feedback on the path forward. These data analyses, which showed that the majority of patients treated with ViaskinTM Peanut achieved sufficient daily application duration to experience clinical benefit, were recently published in two peer-reviewed publications.

Following submission of the data analyses in April and requests for discussion, FDA did not provide further information beyond that the data was being reviewed and the target action date of August 5, 2020 remained unchanged. Given the Company has not yet received an update from the U.S. Food and Drug Administration (FDA) regarding its Biologics License Application (BLA) for ViaskinTM Peanut, the Company has undergone a comprehensive business review to best position DBV for the possibility of a delay in timelines for the ViaskinTM Peanut BLA review. On June 26, 2020, given the absence of clarity from the FDA, DBV announced implementation of a restructuring plan that will provide the flexibility to continue the BLA review process, prepare to bring ViaskinTM Peanut to patients, if approved, and

33

preserve the Company's cash runway. DBV plans to focus on ViaskinTM Peanut and scale down other clinical programs and pre-clinical spend.

In addition, in the United States, investigational ViaskinTM Peanut is being reviewed by the FDA as a biologic under the Federal Food, Drug, and Cosmetic Act, or FDCA, and is evaluated by the Office of Vaccines Research and Review (OVRR), which is also responsible for vaccine evaluation (including COVID-19 vaccines).In response to the COVID-19 pandemic, on March 10, 2020, the FDA announced its intention to postpone most foreign inspections of manufacturing facilities, with requests for Pre- Approval Inspections (PAI) considered on a case-by-case basis. A new PAI has not been scheduled by the FDA for the Viaskin™ Peanut manufacturing facilities.

The continuation of COVID-19 in several countries, including the United States, and the restrictive measures enacted by the European Union on the movement of persons from certain countries, including the United States, constitute obstacles to the conduct, in the near future, of inspections by the U.S. authorities on manufacturing sites in Europe, including the Contract Manufacturing Organizations (CMOs) sites contracted by DBV.

It is uncertain that Viaskin™ Peanut will receive regulatory approval from the BLA and be commercialized. It is also possible that the FDA may require the Company to conduct additional clinical trials for Viaskin™ Peanut.

The clinical trials of DBV's product candidates, as well as manufacturing, and marketing authorization applications to regulators, will be reviewed rigorously by regulatory authorities in the United States and in other countries where the Company intends to develop operations and, if the products are approved, to market them. Before obtaining the necessary regulatory authorizations to market these product candidates, the Company must show, via preclinical and clinical trials, that the product candidate is safe and effective for use in each target indication. This process may take several years and require post- marketing studies and product monitoring, which may generate heavy costs that potentially exceed the external financing currently envisaged by the Company. Only a small percentage of the large number of drugs in development succeed in obtaining all the necessary marketing authorizations. Consequently, even if the Company is able to obtain sufficient financial resources to continue its development and pursue its clinical program, it cannot guarantee that ViaskinTM Peanut or any other product candidate, will be successfully developed or commercialized.

In particular obtaining BLA approval in the United States is a complex, long, costly, and uncertain process, and the FDA may delay, limit, or refuse to approve ViaskinTM Peanut for many reasons, including:

  • A Global pandemic such as COVID 19;
  • FDA may not be able to conduct inspections of the ViankinTM Peanut manufacturing facilities or may have to delay those inspections due to pandemic-related travel restrictions such as Covid-19;
  • The Company may not be able to demonstrate that the product candidates are safe and effective for the treatment of food allergies;
  • The outcomes of the Company's clinical trials submitted or to be submitted in a BLA may not meet the level of statistical or clinical significance required by the FDA for marketing authorization;
  • The FDA may not agree with the number, design, size, conduct, or implementation of those clinical trials;
  • The FDA may require additional clinical trials;
  • The FDA may not approve the formulation, specifications, or product notice of ViaskinTM Peanut or ViaskinTM Milk;

34

  • The FDA may find the data from the preclinical and clinical trials of ViaskinTM Peanut or ViaskinTM Milk insufficient to demonstrate that their therapeutic benefit outweighs their safety risks;
  • The FDA may disagree with the analysis or interpretation of the data from the preclinical and clinical trials conducted by the Company;
  • The FDA may limit the use of the products to a restricted population;
  • The FDA or applicable foreign regulatory body may not approve the Company's manufacturing procedures or facilities or those of the third parties to whom they are subcontracted, or may issue inspection results that require major expense or delay; or;
  • The FDA may change its approval policies or adopt new regulations.

Any of these factors, many of them beyond the Company's control, may compromise its ability to obtain the necessary regulatory approval to market its product candidates.

The Food and Drug Administration (FDA) has granted "Fast Track" and "Breakthrough Therapy" status to ViaskinTM Peanut for the treatment of peanut allergies, as well as "Fast Track" status to ViaskinTM Milk for the treatment of cow's milk protein allergies in children. However, such status may in fact not lead to faster development, regulatory review or marketing authorization than the normal procedure. Furthermore, the FDA may withdraw such status if it believes that the conditions for granting such status are no longer met or no longer justified by the results of the development program.

If global health concerns prevent the FDA or other regulatory authorities from conducting regular inspections, reviews, or other regulatory activities, it could significantly impact the ability of the FDA or other regulatory authorities to review the Company's regulatory submissions, which could have a material adverse effect on its business.

The Company does not believe that the pandemic will cause, a significant delay in the review and potential approval of the BLA for ViaskinTM Peanut by the FDA. However, the impact of the COVID-19 pandemic is hard to assess due the rapidly evolving nature of the situation, and it is possible that the review process for the BLA may be delayed.

Current (including Phase III EPITOPE, EPOPEX, REALISE, PEOPLE) and upcoming clinical trials conducted in the United States, Australia and Europe by the Company have been and may continue to be affected by the COVID-19 outbreak. Patient enrollment and randomization have been delayed as patients remain subject to shelter-in-place orders or other restrictions. The Company has initiated direct-to-patient shipment of clinical trial materials in Europe and, in the United States, to ensure uninterrupted supply of clinical trial materials to its clinical trial subjects. Other than this change in its distribution model for clinical trial materials, there has been no disruption in the supply chain that is necessary to conduct its clinical trials, and the Company believes that it will be able to supply the clinical material needs of its ongoing clinical studies.

If COVID-19 continues to spread in the United States, Europe and elsewhere, the Company may experience additional disruptions that could severely impact our clinical trials, including:

  • Delays in receiving approval from local regulatory authorities to initiate its planned clinical trials;
  • Delays or difficulties in enrolling patients in its clinical trials;
  • Delays or difficulties in clinical site initiation, including difficulties in recruiting clinical site investigators and clinical site staff;
  • Delays in clinical sites receiving the supplies and materials needed to conduct its clinical trials, including interruption in global shipping that may affect the transport of clinical trial materials;
  • Changes in local regulations as part of a response to the COVID-19 pandemic which may require the Company to change the ways in which its clinical trials are conducted, which may result in unexpected costs, or to discontinue the clinical trials altogether;

35

  • Interruption of key clinical trial activities, such as clinical trial site monitoring, due to limitations on travel imposed or recommended by federal or state governments, employers and others, or interruption of clinical trial subject visits and study procedures, the occurrence of which could affect the integrity of clinical trial data;
  • Risk that participants enrolled in its clinical trials will acquire COVID-19 while the clinical trial is ongoing, which could impact the results of the clinical trial, including an increase in the number of observed adverse events;
  • Interruptions or delays in preclinical studies due to restricted or limited operations at research and development laboratory facilities;
  • Delays in necessary interactions with local regulators, ethics committees and other important agencies and contractors due to limitations in employee resources or forced furlough of government employees;
  • Limitations in employee resources that would otherwise be focused on the conduct of our clinical trials, including employee illness, employee's family illness or employee's unwillingness to be in contact with large groups of people; and
  • Refusal of the FDA or other regulators to accept data from clinical trials in geographies impacted by the COVID-19 pandemic.

The extent to which the pandemic impacts its business and clinical trials will depend on future developments, which are highly uncertain and cannot be predicted with confidence, such as the ultimate geographic spread of the disease, the duration of the pandemic, travel restrictions and social distancing in the United States, Europe and other countries, business closures or business disruptions and the effectiveness of actions taken in the United States, Europe and other countries to contain and treat the disease.

To the extent that the Company's business depends almost entirely on ViaskinTM technology, should any of these risks materialize, they could have a significant adverse impact on the Company's activity, financial position, earnings, and growth.

4. THE COMPANY CANNOT GUARANTEE THE COMMERCIAL SUCCESS OF ITS PRODUCTS

Should the Company initially succeed in obtaining Marketing Authorization (MA) for ViaskinTM Peanut, ViaskinTM Milk or its other future therapeutic products, those products may nonetheless take time to gain traction among the medical community, care prescribers, and payers.

The degree of acceptance of each of the Company's products by the market will depend on multiple factors, in particular:

  • Demonstration of the clinical efficacy and safety of the product;
  • The approved therapeutic indications for the product and all the required warnings;
  • Perception of the therapeutic benefits of the product by prescribers, and the Company's ability to educate the medical community on these issues given its limited experience;
  • The support of opinion leaders in the field of allergies;
  • The potential occurrence of adverse reactions once the MA is obtained;
  • The product's ease of use, primarily in terms of its administration (patch);
  • The pricing of the treatment;
  • The reimbursement policies of governmental agencies and other third parties, and;
  • The effective implementation of a scientific publication strategy;

Furthermore, even if the medical community accepts a product as being safe and efficacious for its indicated use, physicians may choose to restrict the use of the product if the Company cannot

demonstrate that, based on experience, clinical data, side-effect profiles and other factors its

product is preferable to any existing drugs or treatments.

Even if the Company's future products (in particular, ViaskinTM Peanut) are able to provide a therapeutic

response to an as-yet unmet need, weak market penetration, due to one or more of the factors

36

described above, may adversely impact the Company's business, outlook, financial position, earnings and growth.

In addition, a global pandemic, such as COVID-19, could also have an impact on the commercial success and launch of a new product. As an example, as a result of the COVID-19 pandemic and the multiple restrictive measures enacted by many countries, commercial and medical organizations and pharmaceutical laboratories have suspended in-person interactions with physicians and patients and are restricted to conducting educational and promotional activities virtually. The implementation of these new virtual promotion initiatives to replace sales forces based in medical centers or hospitals is relatively new, and it is difficult to determine how long these operational restrictions related to COVID- 19 will remain in place and what the longer-term changes will be in terms of promotion to prescribers and the impact on future sales of a new drug.

The Company's commercial performance also depends on the pricing terms set for its products by competent public commissions and bodies and the terms for their reimbursement by social welfare agencies or private insurers in the countries where the Company intends to market its products. In the current context of tight control of healthcare expenditure and the economic and financial crisis, the pressure on selling prices and reimbursement levels is intensifying, notably due to:

  • Price controls introduced by many governments;
  • Increasing restrictions on the reimbursement of certain products as part of fiscal policy;
  • Increasing difficulty in obtaining and maintaining satisfactory reimbursement for drugs.

All these factors will have a direct impact on the Company's ability to derive profits from the products concerned.

5. RISKS RELATING TO GOVERNMENT RESTRICTIONS ON PRICING AND REIMBURSEMENT OF MEDICINES

Government restrictions on pricing and reimbursement, as well as other initiatives by social welfare agencies or payers to limit the reimbursement of healthcare costs may adversely impact the Company's ability to generate revenue should it obtain regulatory approval to market a product.

The control of healthcare costs has become one of the priorities of many governments and the price of drugs has attracted attention on this issue. Governments have shown great interest in implementing cost control programs, notably price controls, reimbursement restrictions, and substitution with generic drugs. The adoption of price and cost control measures, as well as the adoption of more- restrictive policies in jurisdictions where control measures already exist, may limit the Company's potential revenues. The reduction in third-party reimbursement for a product candidate or a decision by a third-party payer not to cover it may reduce the use of that product by physicians and may have a substantial adverse impact on the Company's sales, operating income, and financial position.

For example, in the United States, the first country where the Company intends to market ViaskinTM Peanut if approved by the regulatory authorities, multiple Congressional inquiries and legislative activities at federal and state level are focusing on, among other things, (i) making drug pricing more transparent; (ii) examining the relationship between manufacturers' prices and programs for patients, and (iii) reforming governmental drug reimbursement methods. At federal level, the Trump administration has released a "Blueprint" to lower drug prices and reduce out of pocket costs of drugs. The Blueprint also contains additional proposals to increase drug manufacturer competition, increase the negotiating power of certain federal healthcare programs, and incentivize manufacturers to lower the list price of their products. In addition, a global pandemic such as COVID-19 could also have an impact on the price of and access to new drugs.

37

Other legislative proposals aimed at reforming healthcare reimbursements and government insurance programs in the United States, if approved, may affect the price of future Company products, and reduce the Company's potential revenues.

6. THE COMPANY CANNOT GUARANTEE ACCESS TO THE RAW MATERIALS AND PRODUCTS NEEDED TO MANUFACTURE ITS PRODUCTS

The Company is dependent on specialized third parties for its supply of the materials, chemical or biological products (peanuts, protective film, protein extract) needed to make the patches used in clinical trials or diagnostic patches, and, eventually, its future therapeutic patches. The supply of any of these materials may be reduced or interrupted. The Company has put in place mitigation plans such as building up minimum backup inventories.

The Company's supply chain for materials, chemical or biological products needed to make its patches has not been significantly impacted to date by the COVID-19 pandemic. The Company believes that it has sufficient inventories of raw materials, chemicals and other materials to meet short-term demand. However, if the situation were to continue or if a new global health concerns appears, suppliers could encounter difficulties in supplying the Company due to logistical disruptions, reduced production or financial difficulties.

Should the Company encounter supply problems when sourcing these materials, chemical or biological products, or was unable to maintain existing supply agreements or forge new agreements to develop and manufacture its products in the future, its business, outlook, financial position, earnings, and growth could be significantly impacted.

To avoid such situations, the Company has put in place mitigation plans such as building up backup inventories and intends to adjust its supply strategy by identifying at least one alternative source of raw materials and critical materials (natural proteins and titanium-coated polymer film). This may be a long process given its regulatory implications.

7. THE COMPANY IS DEPENDENT ON ITS SUBCONTRACTORS

For its development activities, the Company uses subcontractors to make its active ingredients (SANOFI), manufacture its patches (FAREVA), and conduct clinical trials (Contract Research Organizations / "CROs").

Although the Company has taken into account the risk of its subcontractors going bankrupt or breaching their contractual obligations, and has put in place measures to hedge against these risks, any failure on the part of third parties to uphold their obligations to the Company could have consequences on the duration of clinical trials or even the ability to conduct them, on the production and availability of products on the market, and on the quality of data and products that have to meet the strict standards (Good Clinical Practice, Good Manufacturing Practice) imposed by regulatory authorities, and may thus delay the commercialization of its products.

Such events could have a significant adverse impact on the Company's activity, outlook, financial position, earnings, and growth.

Furthermore, some of the Company's main suppliers may have signed or may in the future sign similar agreements with some of its competitors and, due to the competitive environment, may be encouraged not to continue or renew their agreements with the Company on commercially acceptable terms. If such were the case, despite the contractual protections put in place by the Company, its key suppliers may be able to benefit from the information acquired during their contractual relationship with the Company to develop competing treatments.

38

The COVID 19 pandemic had an impact on the Company's subcontractors, which reduced their activity following the containment measures put in place in France and implement their Business Continuity Plan.

However, the manufacturing facilities have remained operational and the Company believes that this pandemic will have a limited impact on the short- and medium-term production of patches for clinical trials and the launch of ViaskinTM peanut if approved. In addition, the Company is working closely with its subcontractors to address the production difficulties caused by the pandemic.

8. DEPENDENCY ON PRODUCTION EQUIPMENT

The Company depends on its production equipment for the manufacturing of patches, in particular the ES GEN4.0 machine which was developed by the Company and qualified by its subcontractor under its supervision, and the "Cut Pack" machine.

However, any failure of the equipment could interrupt production and have a significant adverse impact on the Company's business, financial situation, and earnings.

The construction of a second ES GEN4.0 machine is in the process of completion to act as a backup production machine. The COVID 19 pandemic did not cause any delay in the production for this back up equipment.

9. RISK OF LAWSUIT

The Company operates in compliance with applicable laws and regulations, with the support of its internal legal team and external law firms. However, lawsuits may be filed against the Company by competitors or third parties in the course of business. If the lawsuits succeed, the Company's business and operating earnings may be affected. Even if such lawsuits do not result in a judgment against the Company, the proceedings and the time and resources necessary for their resolution may force the Company to use resources that should have been allocated to the Company's business activities.

For example, in December 2018, the Company announced that it had voluntarily withdrawn its BLA application for ViaskinTM Peanut following discussions with the FDA about additional data needed regarding its manufacturing and quality control procedures, and ADS price declined significantly as a result. Following this announcement, A class action complaint was filed on January 15, 2019 in the United States District Court for the District of New Jersey, entitled Travis Ito-Stone v. DBV Technologies, et al., Case No. 2:19-cv-00525. The complaint alleged that the Company and its former Chief Executive Officer, its current Chief Executive Officer, and its Deputy Chief Executive Officer violated certain federal securities laws, specifically under Sections 10(b) and 20(a) of the Exchange Act, and Rule 10b-5 promulgated thereunder. The plaintiffs seeks unspecified damages on behalf of a purported class of purchasers of our securities between February 14, 2018 and December 19, 2018. Subsequently, lead plaintiffs were appointed and an amended complaint was filed on January 24, 2020, adding the Company's former Chief Business Officer as a defendant. In March 2020, the Company announced that the FDA identified questions regarding efficacy, including the impact of patch-site adhesion. Following this announcement, the plaintiffs filed an amended complaint on June 12, 2020, adding allegations relating to the March 2020 announcement and expanding the class period, from February 14, 2018 to March 16, 2020. The Company believes that the allegations contained in the amended complaint are without merit and intend to defend the case vigorously. However, whether or not the plaintiffs' claims have any merit, this type of litigation is often expensive and diverts management's attention and resources, which could adversely affect the operation of the Company's business. If the Company is ultimately required to pay significant defense costs, damages, or settlement amounts, such payments could adversely affect its operations. The Company may be the target of similar litigation in the future. Any future litigation could result in substantial costs and divert management's attention and resources,

39

which could cause serious harm to the Company's business, operating results, and financial condition. The company maintains liability insurance; however, if any costs or expenses associated with this or any other litigation exceed its insurance coverage, the Company may be forced to bear some or all of these costs and expenses directly, which could be substantial. If the Company is ultimately required to pay significant defense costs and/or damages, such payments could adversely affect its operations.

Furthermore, the Company could be the target of other similar litigation in the future. The Company has corporate liability insurance and director and officer liability insurance. However, if the costs associated with such litigation or any other litigation were to exceed its insurance cover, the Company would be obligated to bear all or some of the costs directly.

10. THE COMPANY MAY NOT BE ABLE TO COMMERCIALIZE ITS PRODUCTS BY ITSELF

Given its stage of development, the Company has only limited experience of sales, marketing and distribution of biological drugs. In the near term, the Company will have to acquire marketing skills and develop its sales force, either by itself, or by relying on strategic partners.

On June 26,2020, the Company announced that given the Company has not yet received an update from the U.S. Food and Drug Administration (FDA) regarding its Biologics License Application (BLA) for ViaskinTM Peanut, it has undergone a comprehensive business review to best position DBV for the possibility of a delay in timelines for the ViaskinTM Peanut BLA review. As a result, the Board of Directors has approved the immediate initiation of a global and comprehensive restructuring plan, which is expected to include a significant reduction in workforce. The Company has initiated, in compliance with French law, the mandatory consultation process with DBV's Social and Economic Committee in France. In particular, this restructuring led the Company to reduce the commercial structure that it had begun to put in place in the United States.

The Company may therefore not manage to market its products by itself. The Company may in the future have to find partners to market certain products in some or all of its target territories. The Company may not be able to find partners to sell and market its products on terms economically acceptable for the Company.

In any case, when using partners, the Company would not be able to ensure the same degree of control over the resources deployed for marketing as if it were doing the marketing itself. Therefore, these partners would not be able to implement all the resources set out in their agreements with the Company, and in particular not be able to dedicate those necessary for deep market penetration. Budget restrictions or changes of strategy at partners could delay commercialization or reduce its effectiveness or lead to prioritizing the commercialization of other products instead.

Furthermore, the Company cannot guarantee that any of its partners will not develop, or try to develop, a therapeutic approach that competes with the Company's.

Such events could have a significant adverse impact on the Company's operations, outlook, financial position, earnings, and growth.

11. THE COMPANY MAY LOSE KEY STAFF AND NOT BE ABLE TO ATTRACT NEW QUALIFIED PEOPLE

Given its field of activity in biotechnology and the necessity of fast development in a fiercely competitive market, the Company's success largely depends on the work and expertise of its qualified staff. The temporary or long-term unavailability of such people could alter the Company's ability to achieve its objectives, particularly by depriving it of their know-how and technical expertise.

40

In the context of the ongoing COVID-19 pandemic, the safety of the Company's employees, partners, subcontractors and stakeholders remains an absolute priority. In alignment with public health guidance designed to slow the spread of COVID-19, as of mid-March 2020, the Company has undertaken to adapt its working methods to provide its staff with necessary protections. For employees whose presence on site is not required, in particular support functions in France and the United States, the Company has implemented remote work plans. If the COVID-19 pandemic is prolonged or worsens, it could, however, lead to a potential decrease in the commitment of the employees as a result of short- time work or long periods of telework during periods of containment.

Furthermore, on June 26, 2020, the Company announced that given the Company has not yet received an update from the U.S. Food and Drug Administration (FDA) regarding its Biologics License Application (BLA) for ViaskinTM Peanut, it has undergone a comprehensive business review to best position DBV for the possibility of a delay in timelines for the ViaskinTM Peanut BLA review. As a result, the Board of Directors has approved the immediate initiation of a global and comprehensive restructuring plan, which is expected to include a significant reduction in workforce. The Company has initiated, in compliance with French law, the mandatory consultation process with DBV's Social and Economic Committee in France.

However, as the Company does not yet have any products on the market or any sales, attracting qualified personnel and retaining them is more complex than it might for companies at a more developed stage. The Company's inability to attract or retain key staff could prevent it from achieving its overall objectives thereby significantly adversely impacting its operations, earnings, financial situation, and outlook.

12. CYBERSECURITY, AND INFORMATION SYSTEM CONTINUITY AND PERFORMANCE RISK

Given its size, organizational structure and field of activity, any failure or malfunction, including those due to cybercrime, equipment, software applications or communication networks, especially ERP, and the electronic messaging system, could disrupt operations and entail financial loss for the Company. In addition, as a result of the COVID-19 pandemic, the Company may face increased risks of a cybersecurity breach due to its reliance on internet technology and the number of its employees who are working remotely, which may create additional opportunities for cybercriminals to exploit vulnerabilities.

Consequently, with the growth of cybercrime, the security of information systems is a major challenge for the Company, particularly in terms of data protection, R&D and production know-how, its future customers, its employees and patents. The Company has an IT Department whose mission is to ensure the availability, continuity and performance of the IT services provided, to put in place a risk- management based IT security program to guarantee the control and protection of information (confidentiality, integrity). In addition, the Company launched a major training and awareness campaign for employees related to cybersecurity in light of current remote work arrangements.

However, in the case of a successful cyberattack on its IT systems, the Company may be the victim of theft of confidential data, personal data, damage to its reputation or image, or total or partial interruption of its operations. The development of new products could also be affected, adversely impacting the Company's reputation, financial position, and competitive rights and advantages.
