This Amendment relates to the Ordinary Shares, nominal value EUR0.10 per share (the "Ordinary Shares") of DBV Technologies S.A. (the "Issuer").

Except as specifically provided herein, this Amendment does not modify any of the information previously reported in the Schedule 13D. Capitalized terms used herein shall have the meanings ascribed to them in the Schedule 13D. Information concerning the executive officers and directors of Bpifrance Participations, Bpifrance Investissement, CDC, EPIC and Bpifrance required to be disclosed in response to Item 2 and General Instruction C to Schedule 13D is provided in Exhibit 99.2 to this Amendment and incorporated herein by reference.

None of the Reporting Persons, nor, to the best of their knowledge, any of the persons referred to in Exhibit 99.2 has, during the last five years, been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree, or final order enjoining future violations of, or prohibiting or mandating activities subject to, Federal or state securities laws or finding any violation with respect to such laws. Item 4 of the Schedule 13D is hereby amended and supplemented as follows: Bpifrance Participations sold the amount of Ordinary Shares on the date and at the price set forth below in open market transactions, except as noted otherwise. The sales of the Ordinary Shares were sold in multiple transactions at varying prices. The Reporting Persons undertake to provide the Issuer, any security holder of the Issuer, or the staff of the Securities and Exchange Commission, upon request, full information regarding the number of shares sold at each price within the ranges set forth in this Schedule 13D. January 5, 2026: - 86,777 Ordinary Shares at a weighted average price of EUR3.02 per share (multiple transactions at prices ranging from EUR2.92 to EUR3.19, inclusive). All of the Ordinary Shares that are held of record by the Reporting Persons as reported herein were acquired for investment purposes. The Reporting Persons retain the right to change their investment intent, from time to time to acquire additional Ordinary Shares or other securities of the Issuer, or to sell or otherwise dispose of all or part of the Ordinary Shares or other securities of the Issuer, if any, beneficially owned by them, in any manner permitted by law. The Reporting Persons may engage from time to time in ordinary course transactions with financial institutions with respect to the securities described herein. Except as set forth above, none of the Reporting Persons currently has any plans or proposals which would be related to or would result in any of the matters described in Items 4(a)-(j) of the Instructions to Schedule 13D. However, as part of the ongoing evaluation of investment and investment alternatives, the Reporting Persons may consider such matters and, subject to applicable law, may formulate a plan with respect to such matters, and, from time to time, may hold discussions with or make formal proposals to management or the board of directors of the Issuer or other third parties regarding such matters. Item 5(a) of the Schedule 13D is hereby amended and supplemented as follows: Items 7 through 11 and 13 of each of the cover pages of this Amendment are incorporated herein by reference. As of January 7, 2026, (i) Bpifrance Participations holds directly 10,672,462 Ordinary Shares, which represent 4.6% of the Issuer's outstanding Ordinary Shares, and (ii) Innobio holds directly 226,133 Ordinary Shares, which represents 0.1% of the Issuer's outstanding Ordinary Shares. As of January 7, 2026, neither Bpifrance, Bpifrance Investissement, EPIC nor CDC holds any Ordinary Shares directly. Bpifrance Investissement may be deemed to be the beneficial owner of the 226,133 Ordinary Shares held by Innobio, through its management of Innobio. Bpifrance may be deemed to be the beneficial owner of 10,898,595 Ordinary Shares, which represent 4.7% of the Issuer's outstanding Ordinary Shares, indirectly through its sole ownership of Bpifrance Participations, which is the parent company of Bpifrance Investissement. EPIC and CDC may be deemed to be the beneficial owners of 10,898,595 Ordinary Shares, indirectly through their joint ownership and control of Bpifrance. The percentage of Ordinary Shares beneficially owned by each Reporting Person is based on 232,047,938 Ordinary Shares of the Issuer that are outstanding (based on particular information published by the Issuer) as of December 31, 2025. The amount of outstanding Ordinary Shares disclosed in the prior sentence is calculated under U.S. law, which requires treasury shares to be excluded from the calculation of outstanding shares. Under French law, treasury shares are required to be included in the calculation of outstanding shares. Item 5(b) of the Schedule 13D is hereby amended and supplemented as follows: Items 7 through 11 and 13 of each of the cover pages of this Amendment are incorporated herein by reference. Item 5(c) of the Schedule 13D is hereby amended and supplemented as follows: The information set forth in Item 4 is hereby incorporated by reference into this Item 5(c). Except as disclosed in this Amendment, there have been no reportable transactions with respect to the Ordinary Shares of the Issuer since the filing of Amendment No. 9 to this Schedule 13D, or, to the best of their knowledge, any of the persons referred to in Exhibit 99.2. As of January 7, 2026, pursuant to the exercise of warrants of the Issuer exercised by various holders and Bpifrance Participations' recent sales of Ordinary Shares in the open market, Bpifrance Participations has ceased to be the beneficial owner of more than five percent (5%) of the outstanding Ordinary Shares. Accordingly, the filing of this Amendment 10 represents the final amendment to Schedule 13D for the Reporting Persons and constitutes an exit filing for the Reporting Persons.
