All statements other than present and historical facts and conditions, including forward-looking statements expressing our beliefs, plans, objectives, business strategy, or future events, performance or results of operations and financial position, are forward-looking statements, which involve estimates, assumptions, risks and uncertainties. Therefore, our actual results and performance may differ materially from those expressed in the forward-looking statements.

Forward-looking statements involve inherent risks and uncertainties, including matters not yet known to us or not currently considered material by us.

Actual events or results may differ materially from those expressed or implied in such forward-looking statements as a result of various factors. Factors that could affect future results or cause actual events or results to differ materially from those expressed or implied in forward-looking statements include, but are not limited to:

You should also consider the information contained in “Risk Factors” in this prospectus, the risk factors included in any applicable prospectus supplement, and the risk factors set forth in Part I, Item 1A of our Annual Report on Form 10-K for the fiscal year ended December 31, 2025, incorporated by reference into this prospectus, as well as the information contained in our periodic filings and submissions with the SEC (including our reports on Form 8-K to the extent they are incorporated by reference herein).

Any forward-looking statement speaks only as of the date on which that statement is made. We undertake no obligation to update any forward-looking statement, whether as a result of new information, future events, or otherwise, except as required by law. We qualify all of our forward-looking statements by these cautionary statements.

USE OF PROCEEDS

Except as described in any applicable prospectus supplement and in any free writing prospectuses in connection with a specific offering, we currently intend to use the net proceeds from the sale of the securities offered hereby for operating costs, capital expenditures and for general corporate purposes, including working capital. Accordingly, we will have significant discretion in the use of any net proceeds. We may also use a portion of the net proceeds to invest in or acquire businesses or technologies that we believe are complementary to our own, although we have no current plans, commitments or agreements with respect to any acquisitions as of the date of this prospectus. We may provide additional information on the use of the net proceeds from the sale of the offered securities in an applicable prospectus supplement relating to the offered securities.

DESCRIPTION OF SHARE CAPITAL AND bylaws

The following description of our share capital summarizes certain provisions of our by-laws and relevant provisions of French law. Such summaries do not purport to be complete and are subject to, and are qualified in their entirety by reference to, our by-laws, a copy of which has been filed with the SEC, and to the applicable provisions of French law. We encourage you to read our by-laws and the applicable provisions of French law for additional information.

Holders of ADSs will be able to exercise their rights with respect to the ordinary shares underlying the ADSs only in accordance with the terms of the deposit agreement. See “Description of American Depositary Shares” for more information.

General

As of March 25, 2026, our outstanding share capital, including treasury shares, consisted of a total of 37,751,519 issued ordinary shares, fully paid and with a nominal value €0.13 per share. We have no preferred shares outstanding.

Under French law, our by-laws set forth only our issued and outstanding share capital as of the date of the by-laws. Our fully diluted share capital represents all issued and outstanding shares, as well as all potential shares which may be issued upon exercise or vesting, as applicable, of outstanding warrants (bons de souscription d’actions), restricted stock units (or free shares – actions gratuites) or stock options (options de souscription d’actions), as approved by our shareholders and granted by our board of directors (the “Board of Directors” or the “Board”).

European Investment Bank Warrants

On October 17, 2025, we entered into a €36.0 million credit facility agreement (the “Finance Contract”) with the European Investment Bank (“EIB”), which is comprised of three tranches: €11.0 million for the first tranche (“Tranche A”), €12.0 million for the second tranche (“Tranche B”), and €13.0 million for the third tranche (“Tranche C”, and collectively, the “Tranches”). Concurrent with the execution of the Finance Contract, we entered into a warrant agreement (the “Warrant Agreement”) with EIB, which established the terms of the warrants (bons de souscription d’actions) (the “Warrants”) to be issued to EIB prior to the receipt of borrowings under each Tranche. As of March 25, 2026, we have issued 2,624,421 Warrants to EIB in connection with borrowings under Tranche A and estimate that we will issue approximately 1,100,000 Warrants to EIB in connection with borrowings under Tranche B and approximately 850,000 Warrants in connection with borrowings under Tranche C.

The number of Warrants to be issued in connection with our borrowings under Tranche B and Tranche C will be calculated by dividing the corresponding Tranche borrowings (€12.0 million for Tranche B and €13.0 million for Tranche C) by the euro equivalent 90-day average Nasdaq closing price of our ADSs, multiplied by an increasing factor (3 and 4.2, respectively). The exercise price for each Warrant under each Tranche is determined by taking 90 percent of the euro equivalent 90-day average Nasdaq closing price of our ADSs as of the day prior to issuance of the Warrants for the applicable Tranche, as reduced by a 10% discount.

Each Warrant shall be exercisable for one ordinary share, subject to the anti-dilution adjustments described below. The Warrants have a maturity of twenty years, and outstanding Warrants are exercisable upon the earliest to occur of (i) the maturity date of the applicable Tranche, and (ii) the occurrence of certain events (each an “Exercise Event”), including, (a) the disposal of assets, or shares of subsidiaries holding assets, related to research and development projects, (b) a change of control of the Company, (c) the maturity date of the last Tranche disbursed under the Finance Contract, (d) the prepayment of any principal amount due under the Finance Contract, or (e) an event of default.

Following any Exercise Event and until expiration of the applicable Warrants, EIB may exercise a put option pursuant to which EIB may require us to repurchase all or part of such then-exercisable Warrants at the fair market value, up to a number of Warrants that would result in the put option price being no higher than €20 million in respect of all then-exercisable Warrants.

The Warrants are not transferable except to certain affiliates of EIB or, following an Exercise Event, to any third parties. The Company has a right of first refusal to repurchase Warrants that are offered for sale on the same terms and conditions of such offer except in case of a transfer of the Warrants to certain affiliates of EIB, promotional banks or finance agencies set up by one or more member states of the European Union or any transferees of the credit facility, or otherwise with the prior written approval of the Company.

The Warrant Agreement provides for anti-dilution adjustments triggered by the occurrence of certain events, including: (i) a financial transaction that includes the issuance of new instruments with or without preferential subscription rights of the shareholders (other than the issuance of Warrants in connection with our borrowings under Tranche B and Tranche C), (ii) a free distribution of shares to shareholders, a share split or reverse share split, (iii) an increase of the par value of the shares by incorporation into the share capital of reserves, profits or premiums, (iv) a distribution of reserves or premiums in cash or in kind, (v) a free distribution to our shareholders of any instrument other than our shares, (vi) a repurchase by the Company of our own shares at a price higher than the market price (other than a repurchase of our own shares from EIB or its affiliates), (vii) a change in profit distribution, including through the creation of preferred shares, (viii) a reduction or redemption of the Company’s share capital, (ix) a dividend distribution, (x) the issuance of any instrument (with or without preferential subscription rights), including by way of dividend distribution or capitalization of profits or reserves (including share premium account and any capital redemption reserve), or (xi) a merger or demerger of the Company with or into another entity or other similar operation as a result of which the Company does not survive, or a spin-off. Such anti-dilution adjustments are subject to certain carve-outs, including (y) the issuance of shares at a price higher than the applicable exercise prices of the Warrants or equity-linked securities with conversion or exercise prices higher than the applicable exercise prices of the Warrants and (z) the grant of equity incentive instruments following the date of the Warrant Agreement in an amount not to exceed 10% of the fully diluted capitalization of the Company.

Key Provisions of Our By-laws and French Law Affecting Our Ordinary Shares

The description below reflects the terms of our by-laws, and summarizes the material rights of holders of our ordinary shares under French law. Please note that this is only a summary and is not intended to be exhaustive. For further information, please refer to the full version of our by-laws.

Rights, Preferences and Restrictions Attaching to Ordinary Shares

Dividend and Liquidation Rights (French Law)

Distributable profits in each fiscal year, increased or reduced, as the case may be, by any profit or loss of the Company carried forward from prior years, less any contributions to legal reserves, is available for distribution to our shareholders as dividends, subject to the requirements of French law and our by-laws.

Under French law, we are required to allocate at least 5% of our unconsolidated distributable profits in each fiscal year to a legal reserve fund before dividends may be paid with respect to that year. Such allocation is compulsory until the amount in such reserve fund is equal to 10% of the nominal amount of the registered share capital.

Our shareholders may, upon recommendation of the Board of Directors, decide to allocate all or a part of distributable profits, if any, among special or general reserves, to carry them forward to the next fiscal year as retained earnings, or to allocate them to the shareholders as dividends.

Our by-laws provide that, if so agreed by the shareholders, reserves that are available for distribution under French law and our by-laws may be distributed as dividends, subject to certain limitations.

If we have made distributable profits since the end of the preceding fiscal year (as shown on an interim income statement certified by our statutory auditors), the Board of Directors has the authority under French law, without the approval of shareholders, to distribute interim dividends to the extent of such distributable profits. We have never paid interim dividends.

Under French law, dividends are distributed to shareholders pro rata according to their respective shareholdings. Dividends are payable to holders of shares outstanding on the date of the annual shareholders’ meeting deciding on the distribution of dividends, or in the case of interim dividends, on the date of the Board of Directors meeting approving the distribution of interim dividends. However, holders of newly issued shares may have their rights to dividends limited with respect to certain fiscal years. The actual dividend payment date is decided by the shareholders in an ordinary general meeting or by the Board of Directors in the absence of such a decision by the shareholders. The payment of the dividends must occur within nine months from the end of our fiscal year. An extension of such time frame may be granted by court order. Under French law, dividends not claimed within five years of the date of payment revert to the French State.

Dividends may be paid in cash or, if the shareholders’ meeting so decides, in kind, provided that all the shareholders receive a whole number of assets of the same nature paid in lieu of cash.

Rights to Share in the Surplus in the Event of Liquidation

If the Company is liquidated, our assets remaining after payment of our debts, liquidation expenses and all of our remaining obligations will be distributed first to repay in full the nominal value of the shares, then the surplus, if any, will be distributed pro rata among the shareholders in proportion to the number of shares they hold and subject to any special rights granted to holders of priority shares, if any.

Liability to Further Capital Calls

Shareholders are liable for corporate liabilities only up to the par value of the shares they hold and are not liable to further capital calls of the Company.

Rights to Share in Our Profit

Under French law, each ordinary share entitles its holder to a portion of the corporate profits and assets proportional to the amount of share capital represented thereby.

Voting Rights

Each of our ordinary shares entitles its holder to vote and be represented in the shareholders’ meetings in accordance with the provisions of French law and of our by-laws. The ownership of a share implies, ipso jure, the acceptance of our by-laws and any decision of our shareholders.

Each shareholder is entitled to one vote per share at any general shareholders’ meeting.

Under French law, treasury shares or shares held by entities controlled by us are not entitled to voting rights and are not taken into account for purposes of quorum calculation.

Under French law, directors are elected at the ordinary general shareholders’ meeting by a simple majority vote, and may be removed from office, with or without cause, at any shareholders’ meeting without notice or justification, by a simple majority vote. Our by-laws provide that members of our Board of Directors are elected for a tenure of two years, with terms beginning upon the year of a director’s initial appointment. Pursuant to French law, the sections of the by-laws relating to the number of directors and election and removal of a director from office may only be modified by a resolution adopted by a two-thirds majority of the votes cast by our shareholders present, represented by a proxy or voting by mail at the meeting. The votes cast do not include votes attached to shares held by shareholders who did not take part in the vote, abstained or voted blank or null.

Repurchase of Shares (French Law)

Pursuant to French law, the Company, as a company whose shares are not admitted to trading on a regulated market subject to the provisions of Article L. 433-3 II of the French Monetary and Financial Code, may not acquire its own shares except (a) to reduce its share capital under certain circumstances with the approval of the shareholders at an extraordinary general meeting, (b) to provide shares for distribution to employees under a profit sharing, free share plan or a stock option plan, (c) to offer shares as payment in exchange for assets acquired by the Company in the context of an external growth, merger, demerger or contribution transaction and (d) to provide shares to shareholders as part of a sale procedure organized by the Company. However, the Company may not hold more than 10% of its shares then-issued and 5% for a repurchase of shares to offer them as payment or in exchange for assets acquired by the Company in the context of an external growth, merger, demerger or contribution transaction. A subsidiary of the Company is prohibited by French law from holding shares of the Company and, in the event it becomes a shareholder of the Company, such shareholder must transfer all the shares of the Company that it holds.

Sinking Fund Provisions.

Our by-laws do not provide for any sinking fund provisions.

Actions Necessary to Modify Shareholders’ Rights

Shareholders’ rights may be modified as allowed by French law. Shareholders are only authorized to amend any and all provisions of our by-laws at an extraordinary shareholders’ meeting. The Company may not, however, increase any of the shareholders’ commitments without the prior approval of each shareholder.

Changes in Share Capital (French Law)

Our share capital may be increased only with the approval of the shareholders voting or represented at an extraordinary general meeting, following a recommendation of the Board of Directors. The shareholders may delegate to our Board of Directors either the authority (délégation de compétence) or the power (délégation de pouvoir) to carry out any increase in share capital. If shareholders delegate authority to the Board of Directors at an extraordinary general meeting to decide a capital increase (délégation de compétence), the delegation determines the period (26 months maximum) during which the Board of Directors may decide to carry out the capital increase and the overall threshold of the capital increase. If shareholders delegate power to the Board of Directors at an extraordinary general meeting to carry out a capital increase (délégation de pouvoir) already decided by the extraordinary general meeting, the Board of Directors is granted the power to determine the terms and conditions of the capital increase within the limits set forth by the extraordinary general meeting.

Increases in the share capital may be effected either by the issuance of additional shares (including the creation of a new class of shares) or by an increase in the nominal value of existing shares or by the exercise of rights attached to securities giving access to the share capital. Additional shares may be issued for cash or for assets contributed in kind, upon the conversion of debt securities previously issued by the Company, by capitalization of profits, reserves or share premium, or, subject to certain conditions, by way of offset against indebtedness incurred by the Company. Dividends paid in the form of shares may be distributed in lieu of payment of cash dividends, as described above under “-Dividend and Liquidation Rights (French law)” in this prospectus. French law permits different classes of shares to have liquidation, voting and dividend rights different from those of the outstanding ordinary shares, although we only have one class of shares.

Decisions to increase the share capital through the capitalization of reserves, profits and/or share premium require shareholders’ approval at an extraordinary general shareholders’ meeting, acting under the quorum and majority requirements applicable to ordinary shareholders’ meetings. Increases in share capital effected by an increase in the par value of shares require unanimous approval of the shareholders, unless effected by capitalization of reserves, profits or share premium. All other capital increases require shareholders’ approval at an extraordinary general shareholders’ meeting acting under the regular quorum and majority requirements for such meetings.

Our share capital may be decreased only with the approval of two-thirds of the shareholders voting or represented at an extraordinary general meeting. The share capital may be reduced either by decreasing the nominal value of the shares or by reducing the number of outstanding shares. The conditions under which the registered capital may be reduced will vary depending upon whether or not the reduction is attributable to losses incurred by the Company. The number of outstanding shares may be reduced either by an exchange of shares or by the repurchase and cancellation by the Company of its shares.

Under French law, all the shareholders in each class of shares must be treated equally unless the inequality in treatment is accepted by the affected shareholder. If the reduction is not attributable to losses incurred by us, each shareholder will be offered an opportunity to participate in such capital reduction and may decide whether or not to participate therein.

Attendance and Voting at Shareholders’ Meetings (French Law)

In accordance with French law, there are two types of general shareholders’ meetings, ordinary and extraordinary.

Ordinary general meetings are required for any and all decisions that do not require an extraordinary general meetings, such as the election of directors, the appointment of statutory auditors, the annual accounts and the distribution of dividends.

Extraordinary general meetings are required for approval of matters that amend, or would result in an amendment of, the Company’s by-laws, such as modification of shareholders’ rights, approval of mergers, increases or decreases in share capital (including a waiver of preferential subscription rights), the creation of a new class of shares, the authorization of the issuance of investment certificates or securities convertible or exchangeable into shares and for the sale or transfer of substantially all of the Company’s assets. Such meetings may not, however, increase shareholders’ commitments without the approval of each shareholder.

The Board of Directors is required to convene an annual ordinary general shareholders’ meeting, which must be held within six months of the end of our fiscal year, for approval of the annual accounts.

Other ordinary or extraordinary meetings may be convened at any time during the year. Shareholders’ meetings may be convened by the Board of Directors or, if the Board of Directors fails to call such a meeting, by our statutory auditors or by a court-appointed agent. The court may be requested to appoint an agent either by one or more shareholders holding at least 5% of the registered capital or by an interested party under certain circumstances, or, in case of an urgent matter, by the Work Council (Comité Social et Economique) representing the employees, if any. The notice calling a meeting must state the agenda for such meeting.

French law provides that, at least 15 days before the date set for any general meeting on first notice, and at least ten days before the date set for any general meeting on second notice, a notice of the meeting (avis de convocation) must be sent by mail to all holders of properly registered shares on the date of the notice. A preliminary written notice (avis de réunion) must be sent to each shareholder who has requested to be notified in writing. Under French law, one or several shareholders together holding a specified percentage of share capital (as calculated based on a degressive scale in accordance with French law) may propose resolutions to be submitted for approval by the shareholders at the meeting. Upon our request, The Bank of New York Mellon will send to holders of ADSs notices of shareholders’ meetings and other reports and communications that are made generally available to shareholders. The Work Council, if any, may also require the registration of resolution proposals on the agenda.

Attendance and exercise of voting rights at ordinary and extraordinary general shareholders’ meetings are subject to certain conditions. Shareholders deciding to exercise their voting rights must have their shares registered in their names in the shareholder registry maintained by or on behalf of the Company before the meeting. An ADS holder must timely and properly return its voting instruction card to the depositary to exercise the voting rights relating to the shares represented by its ADSs. The depositary will use reasonable efforts to vote the underlying shares in the manner indicated by the ADS holder. In addition, if an ADS holder does not timely return a voting instruction card or the voting instruction card received is improperly completed or blank, that holder will be deemed to have given the depositary a proxy to vote, and the depositary will vote in favor of all proposals recommended by the Board of Directors and against all proposals that are not recommended by the Board of Directors.

All shareholders who have properly registered their shares have the right to participate in general shareholders’ meetings, either in person, by proxy, or by mail, and to vote according to the number of shares they hold. Each share confers on the shareholder the right to one vote. Under French law, an entity we control, directly or indirectly, is prohibited from holding shares in the Company and, in the event it becomes a shareholder, shares held by such entity would be deprived of voting rights. A proxy may be granted by a shareholder whose name is registered on our share registry to his or her spouse, his/her partner with whom he/she has entered into a civil union, to another shareholder or to a legal representative, in the case of a legal entity, or by sending a proxy to the Company without indication of the beneficiary (in which case such proxy shall be cast in favor of the resolutions supported by the Board of Directors). Under French law, a proxy that is returned without instructions will be counted as present for purposes of the quorum and will be counted (i) in favor of the adoption of the draft resolutions supported by the Board of Directors and (ii) against the adoption of all other draft resolutions that were not expressly supported by the Board of Directors.

The presence in person or by proxy of shareholders holding not less than 33⅓ of the shares entitled to vote is necessary to reach a quorum, in case of either ordinary or extraordinary general meetings. Decisions of the Ordinary General Meeting are taken by a majority of the votes cast by the shareholders present or represented. Decisions of the Extraordinary Shareholders’ Meeting are taken by a two-thirds majority of the votes cast by the shareholders present or represented.

If a quorum is not reached at any meeting, the meeting is adjourned. The quorum requirement upon reconvening of an adjourned meeting is the same as for the first meeting.

At an ordinary general meeting or an extraordinary general meeting deciding upon any capital increase by capitalization of reserves, profits and/or share premium, a simple majority of the votes of the shareholders present or represented by proxy is required to approve a resolution. At any other extraordinary general meeting, two-thirds of the votes cast is required. However, a unanimous vote is required to increase liabilities of shareholders.

Under French law, abstention from voting, blank votes and null votes by those present or those represented by proxy or voting by mail are not counted as votes against the resolution submitted to a shareholder vote at any of the two types of meetings.

In addition to his/her rights to certain information regarding the Company, any shareholder may submit questions during or in advance of a shareholders’ meeting. Questions relating to the agenda for the meeting submitted in advance must be sent to the Board of Directors in written form at least four business days prior to such meeting. The Board of Directors must respond to such questions during the meeting.

Under French law, shareholders can nominate individuals or companies for election to the Board of Directors at a shareholders’ meeting. When the nomination is part of the agenda of the shareholders’ meeting, the nomination must contain the name, age, professional references and professional activity of the nominee for the past five years, as well as the number of shares owned by such candidate, if any. In addition, if the agenda for the shareholders’ meeting includes the election of members of the Board of Directors, any shareholder may require, during the meeting, the nomination of a candidate for election at the Board of Directors at the shareholders’ meeting, even if such shareholder has not followed the nomination procedures. Under French law, shareholders cannot elect a new member of the Board of Directors at a general shareholders meeting if the agenda for the meeting does not include the election of a member of the Board of Directors, unless such nomination is necessary to fill a vacancy due to the previous dismissal of a member.

As set forth in our by-laws, shareholders’ meetings are held at the registered office of the Company or at any other locations specified in the written notice. We do not have staggered or cumulative voting arrangements for the election of directors.

Preferential Subscription Rights (French Law)

Shareholders have preferential rights to subscribe for additional shares issued by the Company for cash on a pro rata basis (or any equity securities of the Company or other securities giving a right, directly or indirectly, to equity securities issued by the Company). Shareholders may waive their preferential rights, either individually or at an extraordinary general meeting by a two-third vote of our shareholders under certain circumstances. Preferential subscription rights, if not previously waived, are transferable during the subscription period relating to a particular offering of shares. U.S. holders of ADSs may not be able to exercise preferential rights for shares underlying their ADSs unless a registration statement under the Securities Act is effective with respect to such rights or an exemption from the registration requirement thereunder is available.

Form and Holding of Shares (French Law)

Form of Shares

Our by-laws provide that shares can only be held in registered form.

Holding of Shares

The shares are registered in the name of the respective owners thereof in the registry maintained by or on behalf of the Company.

Stock certificates evidencing shares, in a manner comparable to that in the United States, are not issued by French companies, but we may issue or cause to be issued confirmations of shareholdings registered in such registry to the persons in whose names the shares are registered. Pursuant to French law, such confirmations do not constitute documents of title and are not negotiable instruments.

Differences in Corporate Law

We are a société anonyme, or S.A., incorporated under the laws of France. French sociétés anonymes differ from Delaware corporations. Set forth below is a summary of certain differences between the provisions of the French Commercial Code applicable to us and the Delaware General Corporation Law relating to shareholders’ rights and protections. This summary is not intended to be a complete discussion of the respective rights and it is qualified in its entirety by reference to Delaware law and French law.

DESCRIPTION OF AMERICAN DEPOSITARY SHARES

American Depositary Shares 

Our ordinary shares are traded on the Nasdaq Global Market represented by ADSs delivered by The Bank of New York Mellon (the “depositary”) pursuant to the deposit agreement (the “deposit agreement”) dated as of July 31, 1997, as amended and restated as of April 7, 2008, among our company, The Bank of New York Mellon, as depositary, and all owners and beneficial owners from time to time of ADSs issued thereunder. Ordinary shares that may be issued pursuant to this prospectus and the applicable prospectus supplement, whether directly or upon conversion of preferred shares or exercise of warrants, may be represented by ADSs. The ADSs may be uncertificated securities or certificated securities evidenced by American Depositary Receipts, or ADRs. Each ADS will represent one share (or a right to receive one share) deposited with the principal Paris office of Uptevia (formerly BNP Paribas Securities Services) (the “custodian”), as custodian for the depositary under the deposit agreement. Each ADS will also represent any other securities, cash or other property which may be held by the depositary. The depositary’s corporate trust office at which the ADSs will be administered and its principal executive office are located at 240 Greenwich Street, New York, NY 10286 (the “Corporate Trust Office”).

You may hold ADSs either directly or indirectly through your broker or other financial institution. If you hold ADSs directly, you are an ADS holder. This description assumes you hold your ADSs directly. If you hold the ADSs indirectly, you must rely on the procedures of your broker or other financial institution to assert the rights of ADS holders described in this section. You should consult with your broker or financial institution to find out what those procedures are.

As an ADS holder, we will not treat you as one of our shareholders and you will not have shareholder rights. French law governs the rights of holders of our ordinary shares. The depositary will be the holder of the shares underlying your ADSs. As a holder of ADSs, you will have ADS holder rights. A deposit agreement among us, the depositary and you, as an ADS holder, and the beneficial owners of ADSs set out ADR holder rights as well as the rights and obligations of the depositary. New York law governs the deposit agreement and the ADRs.

We refer to the shares that are at any time deposited or deemed deposited under the deposit agreement and any and all other securities, cash and property received by the depositary or the custodian in respect thereof and at such time held under the deposit agreement as “Deposited Securities”.

The following is a summary of the material provisions of the deposit agreement. For more complete information, you should read the entire deposit agreement and the form of ADR. Directions on how to obtain copies of those documents are provided under “Where You Can Find More Information About Us.”

Deposit, Transfer and Withdrawal 

French law provides that ownership of shares generally be evidenced only by an inscription in an account in the name of the holder maintained by either the issuer or an authorized intermediary such as a bank. See above “Form and Holding of Shares (French law)” in this prospectus. Thus, all references to the deposit, surrender and delivery of our shares refer only to book-entry transfers and do not contemplate the physical transfers of certificates representing the shares in France.

The depositary has agreed, subject to the terms and conditions of the deposit agreement, that upon notice from the custodian of deposit of our shares, or evidence of rights to receive our shares, and pursuant to appropriate instruments of transfer, it will deliver through its Corporate Trust Office to the person or persons specified by the depositor, ADSs registered in the name or names of such person or persons for the number of ADSs issuable in respect of such deposit, upon payment to the depositary of its fees and expenses and of any taxes or charges.

Upon surrender of ADSs at the Corporate Trust Office of the depositary for the purpose of withdrawal of the Deposited Securities represented by the ADSs, payment of the fees, governmental charges and taxes provided in the deposit agreement and payment of all taxes and governmental charges payable in connection with such surrender and withdrawal, and subject to the provisions of the deposit agreement, our articles of association and the Deposited Securities, the ADS holder is entitled to delivery to it or upon its order of the shares and any other Deposited Securities at the time represented by the ADSs at the Corporate Trust Office of the depositary or at the office of the custodian in Paris. The forwarding for delivery at the Corporate Trust Office of the depositary of cash, other property (other than rights) and documents of title for such delivery will be at the request, risk and expense of the ADS holder.

Dividends, Other Distributions and Rights 

Subject to any restrictions imposed by applicable law, regulations or applicable permits, the depositary will be required to convert or cause to be converted into U.S. dollars, to the extent it can do so on a reasonable basis and can transfer the resulting U.S. dollars to the United States, within one business day or as promptly as practicable, all cash dividends and other cash distributions denominated in a currency other than U.S. dollars, or foreign currency, including euros, that it receives in respect of the Deposited Securities and to distribute the resulting dollar amount (net of fees and expenses of the Depositary) as promptly as practicable to the owners of the ADSs entitled thereto, in proportion to the number of ADSs representing such Deposited Securities held by them. Such distribution may be made upon an averaged or other practicable basis without regard to any distinctions among owners on account of exchange restrictions or the date of delivery of any ADSs or otherwise. The amount distributed will be reduced by any amount on account of taxes to be withheld by us or the depositary.

If any foreign currency cannot be converted to U.S. dollars in whole or in part, and transferred, or if any approval or license of any government or agency thereof which is required for such conversion is denied or in the opinion of the depositary cannot be promptly obtained, the depositary shall, as to the portion of the foreign currency that is convertible, make such conversion and distribution in U.S. dollars to the extent permissible to the owners entitled thereto, and as to the non-convertible balance, distribute foreign currency received by it to each owner requesting in writing such distribution and hold the balance of such foreign currency not so distributed uninvested for the respective accounts of the owners of ADRs entitled thereto, without liability for the interest thereon.

If we declare a dividend in, or free distribution of, our shares, the depositary may, upon prior consultation with and approval of us, and shall if we so request, distribute to the owners, in proportion to the number of ADSs representing such Deposited Securities held by them, respectively, an aggregate number of ADSs that represents the amount of shares received as such dividend or free distribution in respect of such Deposited Securities, subject to the terms and conditions of the deposit agreement with respect to the deposit of our shares and the issuance of ADSs, including the withholding of any tax or other governmental charge and the payment of fees of the depositary. The depositary may withhold any such distribution of ADRs if it has not received satisfactory assurances from us that such distribution does not require registration under the Securities Act or is exempt from registration under the provisions of such Securities Act. In lieu of delivering fractional ADSs in the event of any such dividend or free distribution, the depositary will sell the amount of shares represented by the aggregate of such fractions and distribute the net proceeds in accordance with the deposit agreement. Each ADS shall thenceforth also represent the additional shares distributed upon the Deposited Securities represented thereby.

If we offer or cause to be offered to the holders of any Deposited Securities any rights to subscribe for additional shares or any rights of any other nature, the depositary, after consultation with us, will have discretion as to the procedure to be followed in making such rights available to any owners of ADRs or in disposing of such rights for the benefit of any owners and making the net proceeds available to such owners or, if by the terms of such rights offering or for any other reason, the depositary may not either make such rights available to any owners or dispose of such rights and make the net proceeds available to such owners, or if by the terms of such rights offering or for any other reason, the depositary may not either make such rights available to any owners or dispose of such rights and make the net proceeds available to such owners, then the depositary shall allow the rights to lapse; provided, however, if at the time of the offering of any rights the depositary determines that it is lawful and feasible to make such rights available to all owners or to certain owners of ADSs but not to other owners, the depositary may, and at our request will, distribute to any owner to whom it determines the distribution to be lawful and feasible, in proportion to the number of ADSs held by such owner, warrants or other instruments therefor in such form as it deems appropriate.

If the depositary determines in its discretion that it is not lawful and feasible to make such rights available to all or certain owners, it may, and at our request will, sell the rights, warrants or other instruments in proportion to the number of ADSs held by the owner to whom it has determined it may not lawfully or feasibly make such rights available, and allocate the net proceeds of such sales (net of the fees of the depositary as provided in the deposit agreement, any expenses in connection with such sale and all taxes and governmental charges payable in connection with such rights and subject to the terms and conditions of the deposit agreement) for the account of such owners otherwise entitled to such rights, warrants or other instruments, upon an averaged or other practical basis without regard to any distinctions among such owners because of exchange restrictions or the date of delivery of any ADSs, or otherwise. The depositary will not be responsible for any failure to determine that it may be lawful or feasible to make such rights available to owners in general or any owner or owners in particular.

In circumstances in which rights would not otherwise be distributed, if an owner of ADSs requests the distribution of warrants or other instruments in order to exercise the rights allocable to the ADSs of such owner, the depositary will make such rights available to such owner upon written notice from us to the depositary that (a) we have elected in our sole discretion to permit such rights to be exercised and (b) such owner has executed such documents as we have determined in our sole discretion are reasonably required under applicable law.

If the depositary has distributed warrants or other instruments for rights, upon instruction pursuant to such warrants or other instruments to the depositary from such owner to exercise such rights, upon payment by such owner to the depositary for the account of such owner of an amount equal to the purchase price of our shares to be received upon exercise of the rights, and upon payment of the fees of the depositary as set forth in such warrants or other instruments, the depositary will, on behalf of such owner, exercise the rights and purchase the shares, and we shall cause the shares so purchased to be delivered to the depositary on behalf of such owner. As agent for such owner, the depositary will cause the shares so purchased to be deposited, and will deliver the ADSs to such owner pursuant to the deposit agreement.

The depositary will not offer rights to owners of ADSs unless both the rights and the securities to which such rights relate are either exempt from or not subject to registration under the Securities Act with respect to a distribution to all owners or are registered under the provisions of the Securities Act. Notwithstanding any terms of the deposit agreement to the contrary, we shall have no obligation to prepare and file a registration statement for any purpose. The depositary will not be responsible for any failure to determine that it may be lawful or feasible to make such rights available to owners in general or any owner or owners in particular.

Whenever the depositary shall receive any distribution other than cash, our shares or rights in respect of the Deposited Securities, the depositary will cause the securities or property received by it to be distributed to the owners entitled thereto, after deduction or upon payment of any fees and expenses of the depositary or any taxes or other governmental charges, in proportion to the respective holdings of the owners, in any manner that the depositary, after consultation with us, may reasonably deem equitable and practicable for accomplishing such distribution. If, in the opinion of the depositary, such distribution cannot be made proportionately among the owners entitled thereto, or if for any other reason (including any requirement that we or the depositary withhold an amount on account of taxes or other governmental charges or that such securities must be registered under the Securities Act in order to be distributed) the depositary deems such distribution not feasible, the depositary may, after consultation with us, adopt such method as we may reasonably deem equitable and practicable for the purpose of effecting such distribution, including, but not limited to, the public or private sale of the securities or property thus received, or any part thereof, with the net proceeds of any such sale (net of the fees of the depositary) to be distributed by the depositary to the owners of ADSs entitled thereto as in the case of a distribution received in cash.

Whenever the depositary receives notice from us that we have declared a dividend or other distribution payable in our shares or cash at the election of each holder of our shares, or as otherwise payable if no such election is made pursuant to the terms of the relevant distribution, the depositary will mail a notice to the owners of the ADSs informing them of the distribution and stating that owners of ADSs will be entitled, subject to any applicable provisions of French law, our articles of association or the relevant terms of such distribution, to instruct the depositary as to the form in which such owner elects to receive the distribution. Upon a timely written request from an owner, the depositary will endeavor, insofar as practicable, to make the requested election and distribute cash or shares, as the case may be, to such owners in accordance with the terms of the deposit Agreement. If the depositary does not receive timely instructions from any owner of ADSs as to such owner’s election, the depositary will not make any election with respect to the shares represented by such owner’s ADSs and will distribute the shares or cash it receives, if any, in respect of such shares to the relevant owner.

If the depositary determines that any distribution of property other than cash (including our shares and rights to subscribe therefore) is subject to any tax or other governmental charge which the depositary is obligated to withhold, the depositary may, by public or private sale, dispose of all or a portion of such property in such amounts and in such manner as the depositary deems necessary and practicable to pay such taxes or charges and the depositary will distribute the net proceeds of any such sale after deduction of such taxes or charges to the owners of ADSs entitled thereto in proportion to the number of ADSs held by them, respectively.

Upon any change in nominal or par value, split-up, consolidation or any other reclassification of Deposited Securities, or upon any recapitalization, reorganization, merger or consolidation or sale of assets affecting us or to which we are a party, any securities that shall be received by the depositary or custodian in exchange for, in conversion of, or in respect of Deposited Securities will be treated as new Deposited Securities under the deposit agreement, and the ADSs will thenceforth represent, in addition to the existing Deposited Securities, the right to receive the new Deposited Securities so received in exchange or conversion, unless additional ADSs are delivered pursuant to the following sentence. In any such case the depositary may, with our approval and will if we so request, execute and deliver additional ADSs as in the case of a distribution in shares, or call for the surrender of outstanding ADSs to be exchanged for new ADSs specifically describing such new Deposited Securities.

Record Dates 

Whenever any cash dividend or other cash distribution becomes payable or any distribution other than cash is made, or whenever rights shall be issued with respect to the Deposited Securities, or whenever for any reason the depositary gives effect to a change in the number of our shares that are represented by each ADS, or whenever the depositary shall receive notice of any meeting of holders of shares or other Deposited Securities, or whenever the depositary shall find it necessary or convenient, the depositary will fix a record date, which shall be the same date as for the Shares or a date fixed after consultation with us and as close thereto as practicable (i) for the determination of the owners of ADRs who shall be (a) entitled to receive such dividend, distribution or rights, or the net proceeds of the sale thereof, or (b) entitled to give instructions for the exercise of voting rights at any such meeting, (ii) for fixing the date on or after which each ADS will represent the changed number of shares, all subject to the provisions of the deposit agreement or (iii) to facilitate any other matter for which the record date was set.

Voting of Deposited Securities 

The procedures described herein must be followed in order for owners of ADSs to give voting instructions in respect of the underlying shares.

We will use reasonable efforts to request that the depositary notify owners of ADSs of upcoming votes and ask for voting instructions from such owners. Upon receipt by the depositary of notice of any meeting of holders of shares or other Deposited Securities, the depositary shall, at our request, mail to the owners of the ADRs (i) a copy or summary in English of the notice of such meeting sent by us, (ii) a statement that such owner as of the close of business on a record date established by the depositary pursuant to the deposit agreement will be entitled, subject to any applicable provisions of French law, our articles of association and the Deposited Securities (which provisions, if any, will be summarized in pertinent part in such statement), to instruct the depositary with regard to the exercise of the voting rights, if any, pertaining to the shares or other Deposited Securities represented by such owner’s ADSs, (iii) copies or summaries in English of any materials or other documents provided by us for the purpose of enabling such owners to give instructions for the exercise of such voting rights, and (iv) a voting instruction card setting forth the date established by the depositary for the receipt of such voting instruction card (the “Receipt Date”). The voting instruction card shall include an express indication that such instructions may be given or deemed given (as explained below) (a) if no voting instruction card is received by the depository on or before the Receipt Date, (b) if the depositary receives an improperly completed or blank voting instruction card or (c) if the voting instructions included in the voting instruction card are illegible or unclear. Voting instructions may be given only in respect of a number of ADSs representing an integral number of shares. For a discussion of certain requirements relating to an ADR holder’s right to vote, see above “Ordinary Shares-Attendance and Voting at Shareholders’ Meetings (French Law)” in this prospectus.

Upon receipt by the depositary from an owner of ADSs of a properly completed voting instruction card on or before the Receipt Date, the depositary will either, in its discretion (i) use reasonable efforts, insofar as practical and permitted under any applicable provisions of French law and our articles of association, to vote or cause to be voted the shares represented by such ADSs in accordance with any non-discretionary instructions set forth in such voting instruction card or (ii) forward such instructions to the custodian and the custodian will use its reasonable efforts, insofar as practical and permitted under any applicable provisions of French law and our articles of association, to vote or cause to be voted the shares represented by such ADSs in accordance with any non-discretionary instructions set forth in such voting instruction card. If no voting instruction card is received by the depositary from an owner with respect to any of the shares represented by such owner’s ADSs on or before the Receipt Date, or if the voting instruction card is improperly completed or blank, or if the voting instructions included in the voting instruction card are illegible or unclear, such owner shall be deemed to have instructed the depositary to vote such shares and the depositary shall vote such shares in favor of any resolution proposed or approved by our Board of Directors and against any resolution not so proposed or approved.

We and the depositary may modify or amend the above voting procedures or adopt additional voting procedures from time to time as we and the depositary determine may be necessary or appropriate to comply with French or United States law or our articles of association. There can be no assurance that such modifications, amendments or additional voting procedures will not limit the practical ability of owners and beneficial owners of ADSs to give voting instructions in respect of the shares represented by ADSs or will not include restrictions on the ability of owners and beneficial owners of ADSs to sell ADSs during a specified period of time prior to a shareholders’ meeting.

Reports and Other Communications 

The depositary will make available for inspection by owners of ADSs at its Corporate Trust Office any reports, notices and other communications, including any proxy soliciting material, received from us, which are both (a) received by the depositary, the custodian or a nominee of either as the holder or the Deposited Securities and (b) transmitted to the holders of our shares or other Deposited Securities by us. The depositary will also, at our request, send to the owners copies of such reports, notices and communications when furnished by us pursuant to the deposit agreement, including English-language versions, as applicable, of any such reports, notices and communications.

Amendment and Termination of the Deposit Agreement 

The form of ADSs and any provisions of the deposit agreement may at any time and from time to time be amended by agreement between us and the depositary in any respect which we and the depositary may deem necessary or desirable without the consent of the owners of ADSs. However, any amendment that imposes or increases any fees or charges (other than taxes and other governmental charges, registration fees, cable, telex or facsimile transmission costs, delivery costs or other such expenses), or which otherwise prejudices any substantial existing right of ADS owners, will not take effect as to outstanding ADSs until the expiration of 30 days after notice of any amendment has been given to the owners of outstanding ADSs. Every owner of an ADS at the time any such amendment so becomes effective, will be deemed, by continuing to hold such ADS, to consent and agree to such amendment and to be bound by the deposit agreement as amended thereby. In no event will any amendment impair the right of any owner of an ADS to surrender such ADS and receive therefor the Deposited Securities represented thereby, except to comply with mandatory provisions of applicable law.

The depositary will at any time at our direction terminate the deposit agreement by mailing notice of such termination to the owners of the ADSs then outstanding 30 days prior to the date fixed in such notice for such termination. The depositary may likewise terminate the deposit agreement by mailing notice of such termination to us and the owners of all ADSs then outstanding, if any time 60 days having expired after the depositary will have delivered to us written notice of its election to resign and a successor depositary shall not have been appointed and accepted its appointment, in accordance with the terms of the deposit agreement. If any ADSs remain outstanding after the date of termination of the deposit agreement, the depositary thereafter will discontinue the registration of transfers of ADSs, will suspend the distribution of dividends to the owners thereof and will not give any further notices or perform any further acts under the deposit agreement, except the collection of dividends and other distributions pertaining to the Deposited Securities, the sale of rights and other property and the delivery of underlying shares, together with any dividends or other distributions received with respect thereto and the net proceeds of the sale of any rights or other property, in exchange for surrendered ADSs (after deducting the fees of the depositary and other expenses set forth in the deposit agreement). At any time after the expiration of one year from the date of termination, the depositary may sell the Deposited Securities then held thereunder and hold uninvested the net proceeds of such sale together with any other cash, unsegregated and without liability for interest, for the pro rata benefit of the owners that have not theretofore surrendered their ADSs, such owners thereupon becoming general creditors of the depositary with respect to such net proceeds. After making such a sale, the depositary will be discharged from all obligations under the deposit agreement, except to account for net proceeds and other cash (after deducting the fees of the depositary and other expenses set forth in the deposit agreement and any applicable taxes or other governmental charges).

Charges of Depositary 

The depositary will charge any party depositing or withdrawing shares or any party surrendering ADSs or to whom ADSs are issued (including, without limitation, issuance pursuant to a stock dividend or stock split declared by us or an exchange of stock regarding the ADSs or Deposited Securities or a distribution of ADSs pursuant to the deposit agreement) where applicable; (1) taxes and other governmental charges; (2) such registration fees as may from time to time be in effect for the registration of transfers of shares generally on our share register (or any agent appointed by us for transfers and registration of shares) and applicable to transfers of shares to the name of the depositary or its nominee or the custodian or its nominee on the making of deposits or withdrawals; (3) such cable, telex and facsimile transmissions expenses as are expressly provided in the deposit agreement; (4) such expenses as are incurred by the depositary in the conversion of foreign currency pursuant to the deposit agreement; (5) a fee of $5.00 or less per 100 ADSs (or portion thereof) for the delivery and for the surrender of ADSs pursuant to the deposit agreement; (6) a fee of $0.02 or less per ADS (or portion thereof) for any cash distribution pursuant to the deposit agreement; and (7) a fee for the distribution of securities other than shares under the deposit agreement, such fee being in an amount equal to the fee for the delivery referred to above which would have been charged as a result of the deposit of such securities and (treating all such securities as if they were shares) if they had not been instead distributed by the depositary to owners of the ADSs.

The depositary, pursuant to the deposit agreement, may own and deal in any class of our securities and in ADSs.

Liability of Owner for Taxes 

If any tax or other governmental charge shall become payable by the custodian or the depositary with respect to any ADS or any Deposited Securities represented by the ADSs evidenced by such ADS, such tax or other governmental charge will be payable by the owner of such ADS to the depositary. The depositary may refuse to effect any transfer of such ADS or any withdrawal of Deposited Securities underlying such ADS and may apply such dividends, distributions or the proceeds of any such sale to pay any such tax or other governmental charge and the owner of such ADS will remain liable for any deficiency.

Transfer of American Depositary Shares 

The ADSs are transferable on the books of the depositary, provided that the depositary may close the transfer books (when other than in the ordinary course of business in consultation with us to the extent practicable) at any time, or from time to time, when deemed expedient by it in connection with the performance of its duties or at our written request. As a condition precedent to the execution and delivery, registration of transfer, split-up, combination or surrender of any ADS, the delivery of any distribution thereon, or withdrawal of any Deposited Securities, the Company, depositary, custodian or registrar may require payment from the owner of the ADS or the depositor of the shares of a sum sufficient to reimburse it for any tax or other governmental charge and any stock transfer, registration or conversion fee with respect thereto (including any such tax or charge and fee with respect to shares being deposited or withdrawn) and payment of any applicable fees payable by the holders of ADSs.

The depositary may refuse to effect the transfer of the ADSs, to register the transfer of any ADS or to make any distribution on, or related to, shares until it has received such proof of citizenship or residence, exchange control approval or other information as it may deem necessary or proper. The delivery, transfer, registration of transfer of outstanding ADSs and surrender of ADSs generally may be suspended or refused during any period when the transfer books of the depositary, the Company and the registrar are closed or if any such action is deemed necessary or advisable by the depositary or the Company, at any time or from time to time subject to the provisions of the deposit agreement. Notwithstanding anything in the deposit agreement to the contrary, the surrender of outstanding ADSs and the withdrawal of Deposited Securities may not be suspended except as permitted in General Instruction I(A)(1) to Form F-6 (as such form may be amended from time to time) under the Securities Act, which currently permits suspension only in connection with (i) temporary delays caused by closing the transfer books of the depositary or the Company or the deposit of shares in connection with voting at a shareholders’ meeting or the payment of dividends, (ii) the payment of fees, taxes and similar charges and (iii) compliance with any U.S. or foreign laws or governmental regulations relating to the ADSs or the withdrawal of the Deposited Securities. See “- Voting of Deposited Securities” with respect to additional transfer restrictions.

Acquisitions of ADSs 

Pursuant to the terms of the deposit agreement, all notifications and approvals required pursuant to our articles of association or under French law in connection with the acquisition of shares are applicable in all respects.

General 

Neither the depositary nor we, nor our respective directors, employees, agents or controlling persons (as defined under the Securities Act) will be liable to any owner or beneficial owner of ADSs if by reason of any provision of any present or future law or regulation of the United States, France or any other country, or of any other governmental or regulatory authority or stock exchange or by reason of any provision, present or future, of our articles of association, or by reason of any act of God or war or other circumstance beyond its or our control, the depositary or us or any of its or our directors, employees, agents or controlling persons (as defined under the Securities Act) shall be prevented, delayed or forbidden from, or be subject to any civil or criminal penalty on account of, doing or performing any act or thing which by the terms of the deposit agreement or the Deposited Securities it is provided will be done or performed; nor will we or the depositary incur any liability to any owner or beneficial owner of ADSs by reason of any nonperformance or delay, caused as aforesaid, in the performance of any act or thing which by the terms of the deposit agreement it is provided will or may be done or performed, or by reason of any exercise of, or failure to exercise, any discretion provided for under the deposit agreement or our articles of association.

We and the depositary assume no obligation, nor shall either we or the depositary be subject to any liability under the deposit agreement, except that each agrees to perform their respective obligations specifically set forth therein without negligence or bad faith.

The depositary will keep books at its Corporate Trust Office in the city of New York for the registration of transfers of ADSs, which at all reasonable times will be open for inspection by the owners of ADSs, provided that such inspection will not be for the purpose of communicating with owners in the interest of a business or object other than our business or a matter related to the deposit agreement or the ADSs.

The depositary may appoint one or more co-transfer agents for the purposes of effecting transfers, combinations and split-ups of ADSs at designated transfer offices on behalf of the depositary. In carrying out its functions, a co-transfer agent may require evidence of authority and compliance with applicable laws and other requirements by owners or persons entitled to ADSs and will be entitled to protection and indemnity to the same extent as the depositary.

Governing Law 

The deposit agreement and the ADSs are governed by the laws of the State of New York.

DESCRIPTION OF preferred shares

The particular terms of each issue or series of preferred shares will be described in the related prospectus supplement. This description will include, where applicable, a description of:

Prior to issuing preferred shares, we must convene an extraordinary shareholders meeting at which shareholders would determine the terms and conditions of the preferred shares, decide the issuance of the preferred shares or delegate authority to the Board of Directors to decide the issuance and vote to modify the
by-laws in order to include the characteristics and particular rights of the preferred shares.

The extraordinary general meeting would also decide the maximum aggregate amount of share capital increases which we may carry out by issuing preferred shares, which may not exceed a specified amount of gross issue proceeds to be determined.

Under French law, any payment of dividends to the holders of preferred shares is subject to the following: (i) our net earnings (“bénéfice distribuable”) must be sufficient and available for distribution as indicated in the certified unconsolidated financial statements, and (ii) the vote by the annual shareholders meeting of a resolution approving such distribution of dividends to the holders of preferred shares.

When we issue preferred shares under this prospectus, the shares will be fully paid and non-assessable and, to the extent permitted under French law, will not have, or be subject to, any preemptive or similar rights.

The issuance of preferred shares could adversely affect the voting power of holders of ordinary shares and reduce the likelihood that holders of ordinary shares and ADSs will receive dividend payments and payments upon liquidation. The issuance could have the effect of decreasing the market price of our ADSs. The issuance of preferred shares also could have the effect of delaying, deterring or preventing a change in control of our company.

DESCRIPTION OF WARRANTS

We may issue warrants for the purchase of our preferred or ordinary shares, which may be represented by ADSs, or any combination of the foregoing. Warrants may be offered separately or together with ordinary shares or preferred shares. Each series of warrants will be issued under a separate warrant agreement or indenture to be entered into between us and one or more purchasers of such warrants. The applicable prospectus supplement will include details of the warrant agreements covering the warrants being offered.

The particular terms of each issue or series of warrants will be described in the related prospectus supplement. If warrants for the purchase of preferred or ordinary shares, which may be represented by ADSs, or any combination of the foregoing, are offered, the description will include, where applicable:

Limitations affecting shareholders of a french company

Ownership of ADSs or Shares by Non-French Residents (French Law)

Under French law, there is no limitation on the right of non-French residents or non-French security holders to own, or where applicable, vote securities of a French company.

Nevertheless, any investment: (i) by (a) any non-French citizen, (b) any French citizen not residing in France (within the meaning of Article 4 B of the French Tax Code), (c) any non-French entity or (d) any French entity controlled by one of the aforementioned individuals or entities; (ii) that will result in the relevant investor (a) acquiring control of an entity having its registered office in France or an establishment registered in France, (b) acquiring all or part of a business line of an entity having its registered office in France, (c) for non-EU or non-EEA investors crossing, directly or indirectly, alone or in concert, a 25% threshold of voting rights in an entity having its registered office in France, or (d) crossing, directly or indirectly, alone or in concert, the threshold of 10% of the voting rights of a company incorporated under French law whose shares are admitted to trading on a regulated market; and (iii) developing activities in certain strategic industries related to: (a) activities likely to prejudice national defense interests, participating in the exercise of official authority or likely to prejudice public order and public security (including activities related to weapons, dual-use goods and technologies, IT systems, cryptology, data capturing devices, gambling, toxic agents or data storage), (b) activities relating to essential infrastructure, goods or services (including energy, water, transportation, space, telecom, public health, farm products, media or extraction, processing and recycling of critical raw materials), and (c) research and development activities related to critical technologies (including cybersecurity, artificial intelligence, robotics, additive manufacturing, semiconductors, quantum technologies, energy storage, photonics, renewable energy technologies or biotechnology) or dual-use goods and technologies, is subject to the prior authorization of the French Minister of Economy, which authorization, if granted, may be subject to certain undertakings. The abovementioned (ii)(c) and (d) do not apply either to a natural person who is a national of a Member State of the European Union or of a State party to the Agreement on the European Economic Area that has concluded an administrative assistance agreement with France to combat fraud and tax evasion and who is domiciled in one of these States, or to an entity in which all the members of the control chain, within the meaning of II of Article R. 151-1 of the French Monetary and Financial Code, are governed by the law of one of these States or are nationals of and domiciled in one of these States.

A “fast track” procedure is available for investors whose holdings exceed the 10% threshold but are less than the 25% threshold mentioned above.

This request for prior authorization must be filed with the French Ministry of Economy, which has 30 business days from receipt of the complete file to provide a first decision that may (i) unconditionally authorize the investment or (ii) indicate that further examination is required. In the latter case, the French Ministry of Economy must make a second decision within 45 business days from its first decision. In case of lack of response from the French Ministry of Economy within the abovementioned timeframe, the authorization will be deemed refused. If the authorization is granted, it may be subject to the signature of a letter of undertakings aimed at protecting the French national interests. If an investment requiring the prior authorization of the French Minister of Economy is completed without such authorization having been granted, the French Minister of Economy might direct the relevant investor to (i) submit a request for authorization, (ii) have the previous situation restored at its own expense, or (iii) amend the investment. In the absence of such authorization, the relevant investment shall be deemed null and void. The relevant investor might also be found criminally liable and might be sanctioned with a fine that cannot exceed the greater of: (i) twice the amount of the relevant investment, (ii) 10% of the annual turnover before tax of the target company and (iii) €5 million (for a company) or €1 million (for an individual).

The French Monetary and Financial Code (“CMF”) provides for statistical reporting requirements. Transactions by which non-French residents acquire at least 10% of the share capital or voting rights, or cross the 10% threshold, of a French resident company, are considered as foreign direct investments in France and are subject to statistical reporting requirements (Articles R. 152-1; R.152-3 and R. 152-11 of the CMF). When the investment exceeds €15,000,000, companies must declare foreign transactions directly to the Banque de France within 20 business days following the date of certain direct foreign investments in us, including any purchase of ADSs. A failure to comply with such statistical reporting requirement may be sanctioned by five years’ imprisonment and a fine of a maximum amount equal to twice the amount that should have been reported, in accordance with Article L. 165-1 of the CMF. This amount may be increased fivefold if the violation is made by a legal entity.

PLAN OF DISTRIBUTION

We may sell the securities offered by this prospectus from time to time in one or more transactions, including, without limitation:

The distribution of securities may be effected, from time to time, in one or more transactions, including:

The securities may be sold at a fixed price or prices, which may be changed, or at market prices prevailing at the time of sale, at prices relating to the prevailing market prices or at negotiated prices. The consideration may be paid in cash or another form negotiated by the parties. Agents, underwriters or broker-dealers may be paid compensation for offering and selling the securities. That compensation may be in the form of discounts, concessions or commissions to be received from us or from the purchasers of the securities. Dealers and agents participating in the distribution of the securities may be deemed to be underwriters, and compensation received by them on resale of the securities may be deemed to be underwriting discounts and commissions under the Securities Act. If such dealers or agents were deemed to be underwriters, they may be subject to statutory liabilities under the Securities Act.

We may also make direct sales through subscription rights distributed to our existing shareholders on a pro rata basis, which may or may not be transferable. In any distribution of subscription rights to our shareholders, if all of the underlying securities are not subscribed for, we may then sell the unsubscribed securities directly to third parties or may engage the services of one or more underwriters, dealers or agents, including standby underwriters, to sell the unsubscribed securities to third parties.

Some or all of the securities that we offer through this prospectus may be new issues of securities with no established trading market. Any underwriters to whom we sell our securities for public offering and sale may make a market in those securities, but they will not be obligated to do so and they may discontinue any market making at any time without notice. Accordingly, we cannot assure you of the liquidity of, or continued trading markets for, any securities that we offer.

Agents may, from time to time, solicit offers to purchase the securities. If required, we will name in the applicable prospectus supplement, document incorporated by reference or free writing prospectus, as applicable, any agent involved in the offer or sale of the securities and set forth any compensation payable to the agent. Unless otherwise indicated, any agent will be acting on a best efforts basis for the period of its appointment. Any agent selling the securities covered by this prospectus may be deemed to be an underwriter of the securities.

If underwriters are used in an offering, securities will be acquired by the underwriters for their own account and may be resold, from time to time, in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale, or under delayed delivery contracts or other contractual commitments. Securities may be offered to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters. If an underwriter or underwriters are used in the sale of securities, an underwriting agreement will be executed with the underwriter or underwriters at the time an agreement for the sale is reached. The applicable prospectus supplement will set forth the managing underwriter or underwriters, as well as any other underwriter or underwriters, with respect to a particular underwritten offering of securities, and will set forth the terms of the transactions, including compensation of the underwriters and dealers and the public offering price, if applicable. This prospectus, the applicable prospectus supplement and any applicable free writing prospectus will be used by the underwriters to resell the securities.

If a dealer is used in the sale of the securities, we, or an underwriter, will sell the securities to the dealer, as principal. The dealer may then resell the securities to the public at varying prices to be determined by the dealer at the time of resale. To the extent required, we will set forth in the prospectus supplement, document incorporated by reference, or free writing prospectus, as applicable, the name of the dealer and the terms of the transactions.

We may directly solicit offers to purchase the securities and may make sales of securities directly to institutional investors or others. These persons may be deemed to be underwriters with respect to any resale of the securities. To the extent required, the prospectus supplement, document incorporated by reference or free writing prospectus, as applicable, will describe the terms of any such sales, including the terms of any bidding or auction process, if used.

Agents, underwriters and dealers may be entitled under agreements which may be entered into with us to indemnification by us against specified liabilities, including liabilities incurred under the Securities Act, or to contribution by us to payments they may be required to make in respect of such liabilities. If required, the prospectus supplement, document incorporated by reference or free writing prospectus, as applicable, will describe the terms and conditions of such indemnification or contribution. Some of the agents, underwriters or dealers, or their affiliates may be customers of, engage in transactions with or perform services for us or our subsidiaries or affiliates in the ordinary course of business.

Under the securities laws of some states, the securities offered by this prospectus may be sold in those states only through registered or licensed brokers or dealers.

Any person participating in the distribution of ordinary shares registered under the registration statement that includes this prospectus will be subject to applicable provisions of the Exchange Act, and the applicable SEC rules and regulations, including, among others, Regulation M, which may limit the timing of purchases and sales of any of our ordinary shares by any such person. Furthermore, Regulation M may restrict the ability of any person engaged in the distribution of our ordinary shares to engage in market-making activities with respect to our ordinary shares. These restrictions may affect the marketability of our ordinary shares and the ability of any person or entity to engage in market-making activities with respect to our ordinary shares.

Certain persons participating in an offering may engage in over-allotment, stabilizing transactions, short-covering transactions and penalty bids in accordance with Regulation M under the Exchange Act that stabilize, maintain or otherwise affect the price of the offered securities. If any such activities will occur, they will be described in the applicable prospectus supplement.

ENFORCEABILITY OF CIVIL LIABILITIES

We are a société anonyme, or limited liability corporation, organized under the laws of the Republic of France. Some of our directors and executive officers reside in the Republic of France. In addition, a substantial portion of our assets is located outside of the United States. As a result, it may be difficult for investors:

Nevertheless, a final judgment for the payment of money rendered by any federal or state court in the United States based on civil liability, whether or not predicated solely upon the U.S. federal securities laws, would be recognized and enforced in France provided that a French judge considers that this judgment meets the French legal requirement concerning the recognition and the enforcement of foreign judgments and is capable of being immediately enforced in the United States. A French court is therefore likely to grant the enforcement of a foreign judgment without a review of the merits of the underlying claim, only if (i) that judgment was rendered by a court having jurisdiction over the matter as the dispute is clearly connected to the jurisdiction of such court, the choice of the U.S. court was not fraudulent and the French courts did not have exclusive jurisdiction over the matter, (ii) the judgment does not contravene international public policy rules, as applied by French courts, whether such rules pertain to the merits or to the procedure of the case, including any defense rights, (iii) the judgment is not tainted with fraud and (iv) the judgment does not conflict with a French judgment or a foreign judgment (or an arbitral award) which has become effective in France. In addition, French law guarantees full compensation for the harm suffered but is limited to the actual damages, so the victim does not suffer or benefit from the situation, it being specified that under French law, the principle of awarding punitive damages is not, per se, contrary to public order, provided the amount awarded is not disproportionate to the harm suffered and the defendant’s breach.

As a result, the enforcement, by U.S. investors, of any judgments obtained in U.S. courts in civil and commercial matters, including judgments under the U.S. federal securities law against us or members of our Board of Directors, officers or certain experts named herein who are residents of France or countries other than the United States would be subject to the above conditions.

Finally, there may be doubt as to whether a French court would impose civil liability on us, the members of our Board of Directors, our officers or certain experts named herein in an original action predicated solely upon the U.S. federal securities laws brought in a court of competent jurisdiction in France against us or such members, officers or experts, respectively.

TAXATION

Certain material U.S. federal income tax and, to the extent applicable, material French tax considerations relating to the acquisition, ownership and disposition of any of the securities offered by this prospectus will be set forth in the prospectus supplement pertaining to those securities.

LEGAL MATTERS

Unless otherwise specified in the base prospectus relating to any offering of securities, the validity of the securities and certain legal matters under French and U.S. law will be passed upon by Jones Day. In addition, certain legal matters in connection with any offering of securities under this prospectus will be passed upon for any underwriters, dealers or agents by counsel to be designated at the time of the offering by such underwriters, dealers or agents with respect to matters of French and U.S. law.

RISK FACTORS

Investing in our securities involves a high degree of risk. You should carefully review the specific risks discussed below as well as the risks and uncertainties described under the heading “Risk Factors” contained in any applicable prospectus supplement and any related free writing prospectus, and under similar headings in our most recently filed Annual Report on Form 10-K, as updated by any subsequently filed amendments, periodic reports and other documents that are incorporated by reference into this prospectus, before deciding whether to purchase any of the securities being registered pursuant to the registration statement of which this prospectus is a part.

Additional risks not presently known to us or that we currently believe are immaterial may also significantly impair our business operations.

A substantial number of our securities may be sold in the market following the effective date of the registration statement of which this prospectus forms a part, which may depress the market price for our ADSs.

Sales of a substantial number of our securities in the public market following the effective date of the registration statement of which this prospectus forms a part could cause the market price of our ADSs to decline.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

The statements incorporated by reference or contained in this prospectus discuss our future expectations, contain projections of our results of operations or financial condition, and include other forward-looking information within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”) and Section 21E of the Exchange Act. Our actual results may differ materially from those expressed in forward-looking statements made or incorporated by reference into this prospectus.

All statements other than present and historical facts and conditions, including forward-looking statements expressing our beliefs, plans, objectives, business strategy, or future events, performance or results of operations and financial position, are forward-looking statements, which involve estimates, assumptions, risks and uncertainties. Therefore, our actual results and performance may differ materially from those expressed in the forward-looking statements. Forward-looking statements often, although not always, include words or phrases such as the following: “believe,” “plan,” “intend,” “should,” “estimate,” “expect” and “anticipate” or their negative or similar expressions, which reflect our views about future events and financial performance. Forward-looking statements involve inherent risks and uncertainties, including matters not yet known to us or not currently considered material by us.

Actual events or results may differ materially from those expressed or implied in such forward-looking statements as a result of various factors. Factors that could affect future results or cause actual events or results to differ materially from those expressed or implied in forward-looking statements include, but are not limited to:

You should also consider the information contained in “Risk Factors” in this prospectus, the risk factors included in any applicable prospectus supplement, and the risk factors set forth in Part I, Item 1A of our Annual Report on Form 10-K for the fiscal year ended December 31, 2025, incorporated by reference into this prospectus, as well as the information contained in our periodic filings and submissions with the SEC (including our reports on Form 8-K to the extent they are incorporated by reference herein).

Any forward-looking statement speaks only as of the date on which that statement is made. We undertake no obligation to update any forward-looking statement, whether as a result of new information, future events, or otherwise, except as required by law. We qualify all of our forward-looking statements by these cautionary statements.

USE OF PROCEEDS

We will not receive any of the proceeds from the sale of Warrants and Warrant Shares in this offering. The selling securityholder will receive all of the proceeds from the sale of securities hereunder. However, we will receive proceeds from the exercise of the Warrants by the selling securityholder to the extent they are exercised for cash. Unless otherwise provided in the applicable prospectus supplement, we currently expect to use the aggregate net proceeds from the exercise of the Warrants primarily for working capital, general corporate purposes and in furtherance of our corporate strategy.

DESCRIPTION OF SHARE CAPITAL and bylaws

The following description of our share capital summarizes certain provisions of our by-laws and relevant provisions of French law. Such summaries do not purport to be complete and are subject to, and are qualified in their entirety by reference to, our by-laws, a copy of which has been filed with the SEC, and to the applicable provisions of French law. We encourage you to read our by-laws and the applicable provisions of French law for additional information.

Holders of ADSs will be able to exercise their rights with respect to the ordinary shares underlying the ADSs only in accordance with the terms of the deposit agreement. See “Description of American Depositary Shares” for more information.

General

As of March 25, 2026, our outstanding share capital, including treasury shares, consisted of a total of 37,751,519 issued ordinary shares, fully paid and with a nominal value €0.13 per share. We have no preferred shares outstanding.

Under French law, our by-laws set forth only our issued and outstanding share capital as of the date of the
by-laws. Our fully diluted share capital represents all issued and outstanding shares, as well as all potential shares which may be issued upon exercise or vesting, as applicable, of outstanding warrants (bons de souscription d’actions), restricted stock units (or free shares – actions gratuites) or stock options (options de souscription d’actions), as approved by our shareholders and granted by our board of directors (the “Board of Directors” or the “Board”).

European Investment Bank Warrants

On October 17, 2025, we entered into a €36.0 million credit facility agreement (the “Finance Contract”) with EIB, which is comprised of three tranches: €11.0 million for the first tranche (“Tranche A”), €12.0 million for the second tranche (“Tranche B”), and €13.0 million for the third tranche (“Tranche C”, and collectively, the “Tranches”). Concurrent with the execution of the Finance Contract, we entered into the Warrant Agreement, which established the terms of the Warrants (bons de souscription d’actions) to be issued to EIB prior to the receipt of borrowings under each Tranche. As of March 25, 2026, we have issued 2,624,421 Warrants to EIB in connection with borrowings under Tranche A and estimate that we will issue approximately 1,100,000 Warrants to EIB in connection with borrowings under Tranche B and approximately 850,000 Warrants in connection with borrowings under Tranche C.

The number of Warrants to be issued in connection with our borrowings under Tranche B and Tranche C will be calculated by dividing the corresponding Tranche borrowings (€12.0 million for Tranche B and €13.0 million for Tranche C) by the euro equivalent 90-day average Nasdaq closing price of our ADSs, multiplied by an increasing factor (3 and 4.2, respectively). The exercise price for each Warrant under each Tranche is determined by taking 90 percent of the euro equivalent 90-day average Nasdaq closing price of our ADSs as of the day prior to issuance of the Warrants for the applicable Tranche, as reduced by a 10% discount.

Each Warrant shall be exercisable for one ordinary share, subject to the anti-dilution adjustments described below. The Warrants have a maturity of twenty years, and outstanding Warrants are exercisable upon the earliest to occur of (i) the maturity date of the applicable Tranche, and (ii) the occurrence of certain events (each an “Exercise Event”), including, (a) the disposal of assets, or shares of subsidiaries holding assets, related to research and development projects, (b) a change of control of the Company, (c) the maturity date of the last Tranche disbursed under the Finance Contract, (d) the prepayment of any principal amount due under the Finance Contract, or (e) an event of default.

Following any Exercise Event and until expiration of the applicable Warrants, EIB may exercise a put option pursuant to which EIB may require us to repurchase all or part of such then-exercisable Warrants at the fair market value, up to a number of Warrants that would result in the put option price being no higher than €20 million in respect of all then-exercisable Warrants.

The Warrants are not transferable except to certain affiliates of EIB or, following an Exercise Event, to any third parties. The Company has a right of first refusal to repurchase Warrants that are offered for sale on the same terms and conditions of such offer except in case of a transfer of the Warrants to certain affiliates of EIB, promotional banks or finance agencies set up by one or more member states of the European Union or any transferees of the credit facility, or otherwise with the prior written approval of the Company.

The Warrant Agreement provides for anti-dilution adjustments triggered by the occurrence of certain events, including: (i) a financial transaction that includes the issuance of new instruments with or without preferential subscription rights of the shareholders (other than the issuance of Warrants in connection with our borrowings under Tranche B and Tranche C), (ii) a free distribution of shares to shareholders, a share split or reverse share split, (iii) an increase of the par value of the shares by incorporation into the share capital of reserves, profits or premiums, (iv) a distribution of reserves or premiums in cash or in kind, (v) a free distribution to our shareholders of any instrument other than our shares, (vi) a repurchase by the Company of our own shares at a price higher than the market price (other than a repurchase of our own shares from EIB or its affiliates), (vii) a change in profit distribution, including through the creation of preferred shares, (viii) a reduction or redemption of the Company’s share capital, (ix) a dividend distribution, (x) the issuance of any instrument (with or without preferential subscription rights), including by way of dividend distribution or capitalization of profits or reserves (including share premium account and any capital redemption reserve), or (xi) a merger or demerger of the Company with or into another entity or other similar operation as a result of which the Company does not survive, or a spin-off. Such anti-dilution adjustments are subject to certain carve-outs, including (y) the issuance of shares at a price higher than the applicable exercise prices of the Warrants or equity-linked securities with conversion or exercise prices higher than the applicable exercise prices of the Warrants and (z) the grant of equity incentive instruments following the date of the Warrant Agreement in an amount not to exceed 10% of the fully diluted capitalization of the Company.

Key Provisions of Our By-laws and French Law Affecting Our Ordinary Shares

The description below reflects the terms of our by-laws, and summarizes the material rights of holders of our ordinary shares under French law. Please note that this is only a summary and is not intended to be exhaustive. For further information, please refer to the full version of our by-laws.

Rights, Preferences and Restrictions Attaching to Ordinary Shares

Dividend and Liquidation Rights (French Law)

Distributable profits in each fiscal year, increased or reduced, as the case may be, by any profit or loss of the Company carried forward from prior years, less any contributions to legal reserves, is available for distribution to our shareholders as dividends, subject to the requirements of French law and our by-laws.

Under French law, we are required to allocate at least 5% of our unconsolidated distributable profits in each fiscal year to a legal reserve fund before dividends may be paid with respect to that year. Such allocation is compulsory until the amount in such reserve fund is equal to 10% of the nominal amount of the registered share capital.

Our shareholders may, upon recommendation of the Board of Directors, decide to allocate all or a part of distributable profits, if any, among special or general reserves, to carry them forward to the next fiscal year as retained earnings, or to allocate them to the shareholders as dividends.

Our by-laws provide that, if so agreed by the shareholders, reserves that are available for distribution under French law and our by-laws may be distributed as dividends, subject to certain limitations.

If we have made distributable profits since the end of the preceding fiscal year (as shown on an interim income statement certified by our statutory auditors), the Board of Directors has the authority under French law, without the approval of shareholders, to distribute interim dividends to the extent of such distributable profits. We have never paid interim dividends.

Under French law, dividends are distributed to shareholders pro rata according to their respective shareholdings. Dividends are payable to holders of shares outstanding on the date of the annual shareholders’ meeting deciding on the distribution of dividends, or in the case of interim dividends, on the date of the Board of Directors meeting approving the distribution of interim dividends. However, holders of newly issued shares may have their rights to dividends limited with respect to certain fiscal years. The actual dividend payment date is decided by the shareholders in an ordinary general meeting or by the Board of Directors in the absence of such a decision by the shareholders. The payment of the dividends must occur within nine months from the end of our fiscal year. An extension of such time frame may be granted by court order. Under French law, dividends not claimed within five years of the date of payment revert to the French State.

Dividends may be paid in cash or, if the shareholders’ meeting so decides, in kind, provided that all the shareholders receive a whole number of assets of the same nature paid in lieu of cash.

Rights to Share in the Surplus in the Event of Liquidation

If the Company is liquidated, our assets remaining after payment of our debts, liquidation expenses and all of our remaining obligations will be distributed first to repay in full the nominal value of the shares, then the surplus, if any, will be distributed pro rata among the shareholders in proportion to the number of shares they hold and subject to any special rights granted to holders of priority shares, if any.

Liability to Further Capital Calls

Shareholders are liable for corporate liabilities only up to the par value of the shares they hold and are not liable to further capital calls of the Company.

Rights to Share in Our Profit

Under French law, each ordinary share entitles its holder to a portion of the corporate profits and assets proportional to the amount of share capital represented thereby.

Voting Rights

Each of our ordinary shares entitles its holder to vote and be represented in the shareholders’ meetings in accordance with the provisions of French law and of our by-laws. The ownership of a share implies, ipso jure, the acceptance of our by-laws and any decision of our shareholders.

Each shareholder is entitled to one vote per share at any general shareholders’ meeting.

Under French law, treasury shares or shares held by entities controlled by us are not entitled to voting rights and are not taken into account for purposes of quorum calculation.

Under French law, directors are elected at the ordinary general shareholders’ meeting by a simple majority vote, and may be removed from office, with or without cause, at any shareholders’ meeting without notice or justification, by a simple majority vote. Our by-laws provide that members of our Board of Directors are elected for a tenure of two years, with terms beginning upon the year of a director’s initial appointment. Pursuant to French law, the sections of the by-laws relating to the number of directors and election and removal of a director from office may only be modified by a resolution adopted by a two-thirds majority of the votes cast by our shareholders present, represented by a proxy or voting by mail at the meeting. The votes cast do not include votes attached to shares held by shareholders who did not take part in the vote, abstained or voted blank or null.

Repurchase of Shares (French Law)

Pursuant to French law, the Company, as a company whose shares are not admitted to trading on a regulated market subject to the provisions of Article L. 433-3 II of the French Monetary and Financial Code, may not acquire its own shares except (a) to reduce its share capital under certain circumstances with the approval of the shareholders at an extraordinary general meeting, (b) to provide shares for distribution to employees under a profit sharing, free share plan or a stock option plan, (c) to offer shares as payment in exchange for assets acquired by the Company in the context of an external growth, merger, demerger or contribution transaction and (d) to provide shares to shareholders as part of a sale procedure organized by the Company. However, the Company may not hold more than 10% of its shares then-issued and 5% for a repurchase of shares to offer them as payment or in exchange for assets acquired by the Company in the context of an external growth, merger, demerger or contribution transaction. A subsidiary of the Company is prohibited by French law from holding shares of the Company and, in the event it becomes a shareholder of the Company, such shareholder must transfer all the shares of the Company that it holds.

Sinking Fund Provisions.

Our by-laws do not provide for any sinking fund provisions.

Actions Necessary to Modify Shareholders’ Rights

Shareholders’ rights may be modified as allowed by French law. Shareholders are only authorized to amend any and all provisions of our by-laws at an extraordinary shareholders’ meeting. The Company may not, however, increase any of the shareholders’ commitments without the prior approval of each shareholder.

Changes in Share Capital (French Law)

Our share capital may be increased only with the approval of the shareholders voting or represented at an extraordinary general meeting, following a recommendation of the Board of Directors. The shareholders may delegate to our Board of Directors either the authority (délégation de compétence) or the power (délégation de pouvoir) to carry out any increase in share capital. If shareholders delegate authority to the Board of Directors at an extraordinary general meeting to decide a capital increase (délégation de compétence), the delegation determines the period (26 months maximum) during which the Board of Directors may decide to carry out the capital increase and the overall threshold of the capital increase. If shareholders delegate power to the Board of Directors at an extraordinary general meeting to carry out a capital increase (délégation de pouvoir) already decided by the extraordinary general meeting, the Board of Directors is granted the power to determine the terms and conditions of the capital increase within the limits set forth by the extraordinary general meeting.

Increases in the share capital may be effected either by the issuance of additional shares (including the creation of a new class of shares) or by an increase in the nominal value of existing shares or by the exercise of rights attached to securities giving access to the share capital. Additional shares may be issued for cash or for assets contributed in kind, upon the conversion of debt securities previously issued by the Company, by capitalization of profits, reserves or share premium, or, subject to certain conditions, by way of offset against indebtedness incurred by the Company. Dividends paid in the form of shares may be distributed in lieu of payment of cash dividends, as described above under “-Dividend and Liquidation Rights (French law)” in this prospectus. French law permits different classes of shares to have liquidation, voting and dividend rights different from those of the outstanding ordinary shares, although we only have one class of shares.

Decisions to increase the share capital through the capitalization of reserves, profits and/or share premium require shareholders’ approval at an extraordinary general shareholders’ meeting, acting under the quorum and majority requirements applicable to ordinary shareholders’ meetings. Increases in share capital effected by an increase in the par value of shares require unanimous approval of the shareholders, unless effected by capitalization of reserves, profits or share premium. All other capital increases require shareholders’ approval at an extraordinary general shareholders’ meeting acting under the regular quorum and majority requirements for such meetings.

Our share capital may be decreased only with the approval of two-thirds of the shareholders voting or represented at an extraordinary general meeting. The share capital may be reduced either by decreasing the nominal value of the shares or by reducing the number of outstanding shares. The conditions under which the registered capital may be reduced will vary depending upon whether or not the reduction is attributable to losses incurred by the Company. The number of outstanding shares may be reduced either by an exchange of shares or by the repurchase and cancellation by the Company of its shares.

Under French law, all the shareholders in each class of shares must be treated equally unless the inequality in treatment is accepted by the affected shareholder. If the reduction is not attributable to losses incurred by us, each shareholder will be offered an opportunity to participate in such capital reduction and may decide whether or not to participate therein.

Attendance and Voting at Shareholders’ Meetings (French Law)

In accordance with French law, there are two types of general shareholders’ meetings, ordinary and extraordinary.

Ordinary general meetings are required for any and all decisions that do not require an extraordinary general meetings, such as the election of directors, the appointment of statutory auditors, the annual accounts and the distribution of dividends.

Extraordinary general meetings are required for approval of matters that amend, or would result in an amendment of, the Company’s by-laws, such as modification of shareholders’ rights, approval of mergers, increases or decreases in share capital (including a waiver of preferential subscription rights), the creation of a new class of shares, the authorization of the issuance of investment certificates or securities convertible or exchangeable into shares and for the sale or transfer of substantially all of the Company’s assets. Such meetings may not, however, increase shareholders’ commitments without the approval of each shareholder.

The Board of Directors is required to convene an annual ordinary general shareholders’ meeting, which must be held within six months of the end of our fiscal year, for approval of the annual accounts.

Other ordinary or extraordinary meetings may be convened at any time during the year. Shareholders’ meetings may be convened by the Board of Directors or, if the Board of Directors fails to call such a meeting, by our statutory auditors or by a court-appointed agent. The court may be requested to appoint an agent either by one or more shareholders holding at least 5% of the registered capital or by an interested party under certain circumstances, or, in case of an urgent matter, by the Work Council (Comité Social et Economique) representing the employees, if any. The notice calling a meeting must state the agenda for such meeting.

French law provides that, at least 15 days before the date set for any general meeting on first notice, and at least ten days before the date set for any general meeting on second notice, a notice of the meeting (avis de convocation) must be sent by mail to all holders of properly registered shares on the date of the notice. A preliminary written notice (avis de réunion) must be sent to each shareholder who has requested to be notified in writing. Under French law, one or several shareholders together holding a specified percentage of share capital (as calculated based on a degressive scale in accordance with French law ) may propose resolutions to be submitted for approval by the shareholders at the meeting. Upon our request, The Bank of New York Mellon will send to holders of ADSs notices of shareholders’ meetings and other reports and communications that are made generally available to shareholders. The Work Council, if any, may also require the registration of resolution proposals on the agenda.

Attendance and exercise of voting rights at ordinary and extraordinary general shareholders’ meetings are subject to certain conditions. Shareholders deciding to exercise their voting rights must have their shares registered in their names in the shareholder registry maintained by or on behalf of the Company before the meeting. An ADS holder must timely and properly return its voting instruction card to the depositary to exercise the voting rights relating to the shares represented by its ADSs. The depositary will use reasonable efforts to vote the underlying shares in the manner indicated by the ADS holder. In addition, if an ADS holder does not timely return a voting instruction card or the voting instruction card received is improperly completed or blank, that holder will be deemed to have given the depositary a proxy to vote, and the depositary will vote in favor of all proposals recommended by the Board of Directors and against all proposals that are not recommended by the Board of Directors.

All shareholders who have properly registered their shares have the right to participate in general shareholders’ meetings, either in person, by proxy, or by mail, and to vote according to the number of shares they hold. Each share confers on the shareholder the right to one vote. Under French law, an entity we control, directly or indirectly, is prohibited from holding shares in the Company and, in the event it becomes a shareholder, shares held by such entity would be deprived of voting rights. A proxy may be granted by a shareholder whose name is registered on our share registry to his or her spouse, his/her partner with whom he/she has entered into a civil union, to another shareholder or to a legal representative, in the case of a legal entity, or by sending a proxy to the Company without indication of the beneficiary (in which case such proxy shall be cast in favor of the resolutions supported by the Board of Directors). Under French law, a proxy that is returned without instructions will be counted as present for purposes of the quorum and will be counted (i) in favor of the adoption of the draft resolutions supported by the Board of Directors and (ii) against the adoption of all other draft resolutions that were not expressly supported by the Board of Directors.

The presence in person or by proxy of shareholders holding not less than 33⅓ of the shares entitled to vote is necessary to reach a quorum, in case of either ordinary or extraordinary general meetings. Decisions of the Ordinary General Meeting are taken by a majority of the votes cast by the shareholders present or represented. Decisions of the Extraordinary Shareholders’ Meeting are taken by a two-thirds majority of the votes cast by the shareholders present or represented.

If a quorum is not reached at any meeting, the meeting is adjourned. The quorum requirement upon reconvening of an adjourned meeting is the same as for the first meeting.

At an ordinary general meeting or an extraordinary general meeting deciding upon any capital increase by capitalization of reserves, profits and/or share premium, a simple majority of the votes of the shareholders present or represented by proxy is required to approve a resolution. At any other extraordinary general meeting, two-thirds of the votes cast is required. However, a unanimous vote is required to increase liabilities of shareholders.

Under French law, abstention from voting, blank votes and null votes by those present or those represented by proxy or voting by mail are not counted as votes against the resolution submitted to a shareholder vote at any of the two types of meetings.

In addition to his/her rights to certain information regarding the Company, any shareholder may submit questions during or in advance of a shareholders’ meeting. Questions relating to the agenda for the meeting submitted in advance must be sent to the Board of Directors in written form at least four business days prior to such meeting. The Board of Directors must respond to such questions during the meeting.

Under French law, shareholders can nominate individuals or companies for election to the Board of Directors at a shareholders’ meeting. When the nomination is part of the agenda of the shareholders’ meeting, the nomination must contain the name, age, professional references and professional activity of the nominee for the past five years, as well as the number of shares owned by such candidate, if any. In addition, if the agenda for the shareholders’ meeting includes the election of members of the Board of Directors, any shareholder may require, during the meeting, the nomination of a candidate for election at the Board of Directors at the shareholders’ meeting, even if such shareholder has not followed the nomination procedures. Under French law, shareholders cannot elect a new member of the Board of Directors at a general shareholders meeting if the agenda for the meeting does not include the election of a member of the Board of Directors, unless such nomination is necessary to fill a vacancy due to the previous dismissal of a member.

As set forth in our by-laws, shareholders’ meetings are held at the registered office of the Company or at any other locations specified in the written notice. We do not have staggered or cumulative voting arrangements for the election of directors.

Preferential Subscription Rights (French Law)

Shareholders have preferential rights to subscribe for additional shares issued by the Company for cash on a pro rata basis (or any equity securities of the Company or other securities giving a right, directly or indirectly, to equity securities issued by the Company). Shareholders may waive their preferential rights, either individually or at an extraordinary general meeting by a two-third vote of our shareholders under certain circumstances. Preferential subscription rights, if not previously waived, are transferable during the subscription period relating to a particular offering of shares. U.S. holders of ADSs may not be able to exercise preferential rights for shares underlying their ADSs unless a registration statement under the Securities Act is effective with respect to such rights or an exemption from the registration requirement thereunder is available.

Form and Holding of Shares (French Law)

Form of Shares

Our by-laws provide that shares can only be held in registered form.

Holding of Shares

The shares are registered in the name of the respective owners thereof in the registry maintained by or on behalf of the Company.

Stock certificates evidencing shares, in a manner comparable to that in the United States, are not issued by French companies, but we may issue or cause to be issued confirmations of shareholdings registered in such registry to the persons in whose names the shares are registered. Pursuant to French law, such confirmations do not constitute documents of title and are not negotiable instruments.

Differences in Corporate Law

We are a société anonyme, or S.A., incorporated under the laws of France. French sociétés anonymes differ from Delaware corporations. Set forth below is a summary of certain differences between the provisions of the French Commercial Code applicable to us and the Delaware General Corporation Law relating to shareholders’ rights and protections. This summary is not intended to be a complete discussion of the respective rights and it is qualified in its entirety by reference to Delaware law and French law.

DESCRIPTION OF AMERICAN DEPOSITARY SHARES

American Depositary Shares 

Our ordinary shares are traded on the Nasdaq Global Market represented by ADSs delivered by The Bank of New York Mellon (the “depositary”) pursuant to the deposit agreement (the “deposit agreement”) dated as of July 31, 1997, as amended and restated as of April 7, 2008, among our company, The Bank of New York Mellon, as depositary, and all owners and beneficial owners from time to time of ADSs issued thereunder. Ordinary shares that may be issued pursuant to this prospectus and the applicable prospectus supplement, whether directly or upon conversion of preferred shares or exercise of warrants, may be represented by ADSs. The ADSs may be uncertificated securities or certificated securities evidenced by American Depositary Receipts, or ADRs. Each ADS will represent one share (or a right to receive one share) deposited with the principal Paris office of Uptevia (formerly BNP Paribas Securities Services) (the “custodian”), as custodian for the depositary under the deposit agreement. Each ADS will also represent any other securities, cash or other property which may be held by the depositary. The depositary’s corporate trust office at which the ADSs will be administered and its principal executive office are located at 240 Greenwich Street, New York, NY 10286 (the “Corporate Trust Office”).

You may hold ADSs either directly or indirectly through your broker or other financial institution. If you hold ADSs directly, you are an ADS holder. This description assumes you hold your ADSs directly. If you hold the ADSs indirectly, you must rely on the procedures of your broker or other financial institution to assert the rights of ADS holders described in this section. You should consult with your broker or financial institution to find out what those procedures are.

As an ADS holder, we will not treat you as one of our shareholders and you will not have shareholder rights. French law governs the rights of holders of our ordinary shares. The depositary will be the holder of the shares underlying your ADSs. As a holder of ADSs, you will have ADS holder rights. A deposit agreement among us, the depositary and you, as an ADS holder, and the beneficial owners of ADSs set out ADR holder rights as well as the rights and obligations of the depositary. New York law governs the deposit agreement and the ADRs.

We refer to the shares that are at any time deposited or deemed deposited under the deposit agreement and any and all other securities, cash and property received by the depositary or the custodian in respect thereof and at such time held under the deposit agreement as “Deposited Securities”.

The following is a summary of the material provisions of the deposit agreement. For more complete information, you should read the entire deposit agreement and the form of ADR. Directions on how to obtain copies of those documents are provided under “Where You Can Find More Information About Us.”

Deposit, Transfer and Withdrawal 

French law provides that ownership of shares generally be evidenced only by an inscription in an account in the name of the holder maintained by either the issuer or an authorized intermediary such as a bank. See above “Form and Holding of Shares (French law)” in this prospectus. Thus, all references to the deposit, surrender and delivery of our shares refer only to book-entry transfers and do not contemplate the physical transfers of certificates representing the shares in France.

The depositary has agreed, subject to the terms and conditions of the deposit agreement, that upon notice from the custodian of deposit of our shares, or evidence of rights to receive our shares, and pursuant to appropriate instruments of transfer, it will deliver through its Corporate Trust Office to the person or persons specified by the depositor, ADSs registered in the name or names of such person or persons for the number of ADSs issuable in respect of such deposit, upon payment to the depositary of its fees and expenses and of any taxes or charges.

Upon surrender of ADSs at the Corporate Trust Office of the depositary for the purpose of withdrawal of the Deposited Securities represented by the ADSs, payment of the fees, governmental charges and taxes provided in the deposit agreement and payment of all taxes and governmental charges payable in connection with such surrender and withdrawal, and subject to the provisions of the deposit agreement, our articles of association and the Deposited Securities, the ADS holder is entitled to delivery to it or upon its order of the shares and any other Deposited Securities at the time represented by the ADSs at the Corporate Trust Office of the depositary or at the office of the custodian in Paris. The forwarding for delivery at the Corporate Trust Office of the depositary of cash, other property (other than rights) and documents of title for such delivery will be at the request, risk and expense of the ADS holder.

Dividends, Other Distributions and Rights 

Subject to any restrictions imposed by applicable law, regulations or applicable permits, the depositary will be required to convert or cause to be converted into U.S. dollars, to the extent it can do so on a reasonable basis and can transfer the resulting U.S. dollars to the United States, within one business day or as promptly as practicable, all cash dividends and other cash distributions denominated in a currency other than U.S. dollars, or foreign currency, including euros, that it receives in respect of the Deposited Securities and to distribute the resulting dollar amount (net of fees and expenses of the Depositary) as promptly as practicable to the owners of the ADSs entitled thereto, in proportion to the number of ADSs representing such Deposited Securities held by them. Such distribution may be made upon an averaged or other practicable basis without regard to any distinctions among owners on account of exchange restrictions or the date of delivery of any ADSs or otherwise. The amount distributed will be reduced by any amount on account of taxes to be withheld by us or the depositary.

If any foreign currency cannot be converted to U.S. dollars in whole or in part, and transferred, or if any approval or license of any government or agency thereof which is required for such conversion is denied or in the opinion of the depositary cannot be promptly obtained, the depositary shall, as to the portion of the foreign currency that is convertible, make such conversion and distribution in U.S. dollars to the extent permissible to the owners entitled thereto, and as to the non-convertible balance, distribute foreign currency received by it to each owner requesting in writing such distribution and hold the balance of such foreign currency not so distributed uninvested for the respective accounts of the owners of ADRs entitled thereto, without liability for the interest thereon.

If we declare a dividend in, or free distribution of, our shares, the depositary may, upon prior consultation with and approval of us, and shall if we so request, distribute to the owners, in proportion to the number of ADSs representing such Deposited Securities held by them, respectively, an aggregate number of ADSs that represents the amount of shares received as such dividend or free distribution in respect of such Deposited Securities, subject to the terms and conditions of the deposit agreement with respect to the deposit of our shares and the issuance of ADSs, including the withholding of any tax or other governmental charge and the payment of fees of the depositary. The depositary may withhold any such distribution of ADRs if it has not received satisfactory assurances from us that such distribution does not require registration under the Securities Act or is exempt from registration under the provisions of such Securities Act. In lieu of delivering fractional ADSs in the event of any such dividend or free distribution, the depositary will sell the amount of shares represented by the aggregate of such fractions and distribute the net proceeds in accordance with the deposit agreement. Each ADS shall thenceforth also represent the additional shares distributed upon the Deposited Securities represented thereby.

If we offer or cause to be offered to the holders of any Deposited Securities any rights to subscribe for additional shares or any rights of any other nature, the depositary, after consultation with us, will have discretion as to the procedure to be followed in making such rights available to any owners of ADRs or in disposing of such rights for the benefit of any owners and making the net proceeds available to such owners or, if by the terms of such rights offering or for any other reason, the depositary may not either make such rights available to any owners or dispose of such rights and make the net proceeds available to such owners, or if by the terms of such rights offering or for any other reason, the depositary may not either make such rights available to any owners or dispose of such rights and make the net proceeds available to such owners, then the depositary shall allow the rights to lapse; provided, however, if at the time of the offering of any rights the depositary determines that it is lawful and feasible to make such rights available to all owners or to certain owners of ADSs but not to other owners, the depositary may, and at our request will, distribute to any owner to whom it determines the distribution to be lawful and feasible, in proportion to the number of ADSs held by such owner, warrants or other instruments therefor in such form as it deems appropriate.

If the depositary determines in its discretion that it is not lawful and feasible to make such rights available to all or certain owners, it may, and at our request will, sell the rights, warrants or other instruments in proportion to the number of ADSs held by the owner to whom it has determined it may not lawfully or feasibly make such rights available, and allocate the net proceeds of such sales (net of the fees of the depositary as provided in the deposit agreement, any expenses in connection with such sale and all taxes and governmental charges payable in connection with such rights and subject to the terms and conditions of the deposit agreement) for the account of such owners otherwise entitled to such rights, warrants or other instruments, upon an averaged or other practical basis without regard to any distinctions among such owners because of exchange restrictions or the date of delivery of any ADSs, or otherwise. The depositary will not be responsible for any failure to determine that it may be lawful or feasible to make such rights available to owners in general or any owner or owners in particular.

In circumstances in which rights would not otherwise be distributed, if an owner of ADSs requests the distribution of warrants or other instruments in order to exercise the rights allocable to the ADSs of such owner, the depositary will make such rights available to such owner upon written notice from us to the depositary that (a) we have elected in our sole discretion to permit such rights to be exercised and (b) such owner has executed such documents as we have determined in our sole discretion are reasonably required under applicable law.

If the depositary has distributed warrants or other instruments for rights, upon instruction pursuant to such warrants or other instruments to the depositary from such owner to exercise such rights, upon payment by such owner to the depositary for the account of such owner of an amount equal to the purchase price of our shares to be received upon exercise of the rights, and upon payment of the fees of the depositary as set forth in such warrants or other instruments, the depositary will, on behalf of such owner, exercise the rights and purchase the shares, and we shall cause the shares so purchased to be delivered to the depositary on behalf of such owner. As agent for such owner, the depositary will cause the shares so purchased to be deposited, and will deliver the ADSs to such owner pursuant to the deposit agreement.

The depositary will not offer rights to owners of ADSs unless both the rights and the securities to which such rights relate are either exempt from or not subject to registration under the Securities Act with respect to a distribution to all owners or are registered under the provisions of the Securities Act. Notwithstanding any terms of the deposit agreement to the contrary, we shall have no obligation to prepare and file a registration statement for any purpose. The depositary will not be responsible for any failure to determine that it may be lawful or feasible to make such rights available to owners in general or any owner or owners in particular.

Whenever the depositary shall receive any distribution other than cash, our shares or rights in respect of the Deposited Securities, the depositary will cause the securities or property received by it to be distributed to the owners entitled thereto, after deduction or upon payment of any fees and expenses of the depositary or any taxes or other governmental charges, in proportion to the respective holdings of the owners, in any manner that the depositary, after consultation with us, may reasonably deem equitable and practicable for accomplishing such distribution. If, in the opinion of the depositary, such distribution cannot be made proportionately among the owners entitled thereto, or if for any other reason (including any requirement that we or the depositary withhold an amount on account of taxes or other governmental charges or that such securities must be registered under the Securities Act in order to be distributed) the depositary deems such distribution not feasible, the depositary may, after consultation with us, adopt such method as we may reasonably deem equitable and practicable for the purpose of effecting such distribution, including, but not limited to, the public or private sale of the securities or property thus received, or any part thereof, with the net proceeds of any such sale (net of the fees of the depositary) to be distributed by the depositary to the owners of ADSs entitled thereto as in the case of a distribution received in cash.

Whenever the depositary receives notice from us that we have declared a dividend or other distribution payable in our shares or cash at the election of each holder of our shares, or as otherwise payable if no such election is made pursuant to the terms of the relevant distribution, the depositary will mail a notice to the owners of the ADSs informing them of the distribution and stating that owners of ADSs will be entitled, subject to any applicable provisions of French law, our articles of association or the relevant terms of such distribution, to instruct the depositary as to the form in which such owner elects to receive the distribution. Upon a timely written request from an owner, the depositary will endeavor, insofar as practicable, to make the requested election and distribute cash or shares, as the case may be, to such owners in accordance with the terms of the deposit Agreement. If the depositary does not receive timely instructions from any owner of ADSs as to such owner’s election, the depositary will not make any election with respect to the shares represented by such owner’s ADSs and will distribute the shares or cash it receives, if any, in respect of such shares to the relevant owner.

If the depositary determines that any distribution of property other than cash (including our shares and rights to subscribe therefore) is subject to any tax or other governmental charge which the depositary is obligated to withhold, the depositary may, by public or private sale, dispose of all or a portion of such property in such amounts and in such manner as the depositary deems necessary and practicable to pay such taxes or charges and the depositary will distribute the net proceeds of any such sale after deduction of such taxes or charges to the owners of ADSs entitled thereto in proportion to the number of ADSs held by them, respectively.

Upon any change in nominal or par value, split-up, consolidation or any other reclassification of Deposited Securities, or upon any recapitalization, reorganization, merger or consolidation or sale of assets affecting us or to which we are a party, any securities that shall be received by the depositary or custodian in exchange for, in conversion of, or in respect of Deposited Securities will be treated as new Deposited Securities under the deposit agreement, and the ADSs will thenceforth represent, in addition to the existing Deposited Securities, the right to receive the new Deposited Securities so received in exchange or conversion, unless additional ADSs are delivered pursuant to the following sentence. In any such case the depositary may, with our approval and will if we so request, execute and deliver additional ADSs as in the case of a distribution in shares, or call for the surrender of outstanding ADSs to be exchanged for new ADSs specifically describing such new Deposited Securities.

Whenever any cash dividend or other cash distribution becomes payable or any distribution other than cash is made, or whenever rights shall be issued with respect to the Deposited Securities, or whenever for any reason the depositary gives effect to a change in the number of our shares that are represented by each ADS, or whenever the depositary shall receive notice of any meeting of holders of shares or other Deposited Securities, or whenever the depositary shall find it necessary or convenient, the depositary will fix a record date, which shall be the same date as for the Shares or a date fixed after consultation with us and as close thereto as practicable (i) for the determination of the owners of ADRs who shall be (a) entitled to receive such dividend, distribution or rights, or the net proceeds of the sale thereof, or (b) entitled to give instructions for the exercise of voting rights at any such meeting, (ii) for fixing the date on or after which each ADS will represent the changed number of shares, all subject to the provisions of the deposit agreement or (iii) to facilitate any other matter for which the record date was set.

Voting of Deposited Securities 

The procedures described herein must be followed in order for owners of ADSs to give voting instructions in respect of the underlying shares.

We will use reasonable efforts to request that the depositary notify owners of ADSs of upcoming votes and ask for voting instructions from such owners. Upon receipt by the depositary of notice of any meeting of holders of shares or other Deposited Securities, the depositary shall, at our request, mail to the owners of the ADRs (i) a copy or summary in English of the notice of such meeting sent by us, (ii) a statement that such owner as of the close of business on a record date established by the depositary pursuant to the deposit agreement will be entitled, subject to any applicable provisions of French law, our articles of association and the Deposited Securities (which provisions, if any, will be summarized in pertinent part in such statement), to instruct the depositary with regard to the exercise of the voting rights, if any, pertaining to the shares or other Deposited Securities represented by such owner’s ADSs, (iii) copies or summaries in English of any materials or other documents provided by us for the purpose of enabling such owners to give instructions for the exercise of such voting rights, and (iv) a voting instruction card setting forth the date established by the depositary for the receipt of such voting instruction card (the “Receipt Date”). The voting instruction card shall include an express indication that such instructions may be given or deemed given (as explained below) (a) if no voting instruction card is received by the depository on or before the Receipt Date, (b) if the depositary receives an improperly completed or blank voting instruction card or (c) if the voting instructions included in the voting instruction card are illegible or unclear. Voting instructions may be given only in respect of a number of ADSs representing an integral number of shares. For a discussion of certain requirements relating to an ADR holder’s right to vote, see above “Ordinary Shares-Attendance and Voting at Shareholders’ Meetings (French Law)” in this prospectus.

Upon receipt by the depositary from an owner of ADSs of a properly completed voting instruction card on or before the Receipt Date, the depositary will either, in its discretion (i) use reasonable efforts, insofar as practical and permitted under any applicable provisions of French law and our articles of association, to vote or cause to be voted the shares represented by such ADSs in accordance with any non-discretionary instructions set forth in such voting instruction card or (ii) forward such instructions to the custodian and the custodian will use its reasonable efforts, insofar as practical and permitted under any applicable provisions of French law and our articles of association, to vote or cause to be voted the shares represented by such ADSs in accordance with any non-discretionary instructions set forth in such voting instruction card. If no voting instruction card is received by the depositary from an owner with respect to any of the shares represented by such owner’s ADSs on or before the Receipt Date, or if the voting instruction card is improperly completed or blank, or if the voting instructions included in the voting instruction card are illegible or unclear, such owner shall be deemed to have instructed the depositary to vote such shares and the depositary shall vote such shares in favor of any resolution proposed or approved by our Board of Directors and against any resolution not so proposed or approved.

We and the depositary may modify or amend the above voting procedures or adopt additional voting procedures from time to time as we and the depositary determine may be necessary or appropriate to comply with French or United States law or our articles of association. There can be no assurance that such modifications, amendments or additional voting procedures will not limit the practical ability of owners and beneficial owners of ADSs to give voting instructions in respect of the shares represented by ADSs or will not include restrictions on the ability of owners and beneficial owners of ADSs to sell ADSs during a specified period of time prior to a shareholders’ meeting.

Reports and Other Communications 

The depositary will make available for inspection by owners of ADSs at its Corporate Trust Office any reports, notices and other communications, including any proxy soliciting material, received from us, which are both (a) received by the depositary, the custodian or a nominee of either as the holder or the Deposited Securities and (b) transmitted to the holders of our shares or other Deposited Securities by us. The depositary will also, at our request, send to the owners copies of such reports, notices and communications when furnished by us pursuant to the deposit agreement, including English-language versions, as applicable, of any such reports, notices and communications.

Amendment and Termination of the Deposit Agreement 

The form of ADSs and any provisions of the deposit agreement may at any time and from time to time be amended by agreement between us and the depositary in any respect which we and the depositary may deem necessary or desirable without the consent of the owners of ADSs. However, any amendment that imposes or increases any fees or charges (other than taxes and other governmental charges, registration fees, cable, telex or facsimile transmission costs, delivery costs or other such expenses), or which otherwise prejudices any substantial existing right of ADS owners, will not take effect as to outstanding ADSs until the expiration of 30 days after notice of any amendment has been given to the owners of outstanding ADSs. Every owner of an ADS at the time any such amendment so becomes effective, will be deemed, by continuing to hold such ADS, to consent and agree to such amendment and to be bound by the deposit agreement as amended thereby. In no event will any amendment impair the right of any owner of an ADS to surrender such ADS and receive therefor the Deposited Securities represented thereby, except to comply with mandatory provisions of applicable law.

The depositary will at any time at our direction terminate the deposit agreement by mailing notice of such termination to the owners of the ADSs then outstanding 30 days prior to the date fixed in such notice for such termination. The depositary may likewise terminate the deposit agreement by mailing notice of such termination to us and the owners of all ADSs then outstanding, if any time 60 days having expired after the depositary will have delivered to us written notice of its election to resign and a successor depositary shall not have been appointed and accepted its appointment, in accordance with the terms of the deposit agreement. If any ADSs remain outstanding after the date of termination of the deposit agreement, the depositary thereafter will discontinue the registration of transfers of ADSs, will suspend the distribution of dividends to the owners thereof and will not give any further notices or perform any further acts under the deposit agreement, except the collection of dividends and other distributions pertaining to the Deposited Securities, the sale of rights and other property and the delivery of underlying shares, together with any dividends or other distributions received with respect thereto and the net proceeds of the sale of any rights or other property, in exchange for surrendered ADSs (after deducting the fees of the depositary and other expenses set forth in the deposit agreement). At any time after the expiration of one year from the date of termination, the depositary may sell the Deposited Securities then held thereunder and hold uninvested the net proceeds of such sale together with any other cash, unsegregated and without liability for interest, for the pro rata benefit of the owners that have not theretofore surrendered their ADSs, such owners thereupon becoming general creditors of the depositary with respect to such net proceeds. After making such a sale, the depositary will be discharged from all obligations under the deposit agreement, except to account for net proceeds and other cash (after deducting the fees of the depositary and other expenses set forth in the deposit agreement and any applicable taxes or other governmental charges).

Charges of Depositary 

The depositary will charge any party depositing or withdrawing shares or any party surrendering ADSs or to whom ADSs are issued (including, without limitation, issuance pursuant to a stock dividend or stock split declared by us or an exchange of stock regarding the ADSs or Deposited Securities or a distribution of ADSs pursuant to the deposit agreement) where applicable; (1) taxes and other governmental charges; (2) such registration fees as may from time to time be in effect for the registration of transfers of shares generally on our share register (or any agent appointed by us for transfers and registration of shares) and applicable to transfers of shares to the name of the depositary or its nominee or the custodian or its nominee on the making of deposits or withdrawals; (3) such cable, telex and facsimile transmissions expenses as are expressly provided in the deposit agreement; (4) such expenses as are incurred by the depositary in the conversion of foreign currency pursuant to the deposit agreement; (5) a fee of $5.00 or less per 100 ADSs (or portion thereof) for the delivery and for the surrender of ADSs pursuant to the deposit agreement; (6) a fee of $0.02 or less per ADS (or portion thereof) for any cash distribution pursuant to the deposit agreement; and (7) a fee for the distribution of securities other than shares under the deposit agreement, such fee being in an amount equal to the fee for the delivery referred to above which would have been charged as a result of the deposit of such securities and (treating all such securities as if they were shares) if they had not been instead distributed by the depositary to owners of the ADSs.

The depositary, pursuant to the deposit agreement, may own and deal in any class of our securities and in ADSs.

Liability of Owner for Taxes 

If any tax or other governmental charge shall become payable by the custodian or the depositary with respect to any ADS or any Deposited Securities represented by the ADSs evidenced by such ADS, such tax or other governmental charge will be payable by the owner of such ADS to the depositary. The depositary may refuse to effect any transfer of such ADS or any withdrawal of Deposited Securities underlying such ADS and may apply such dividends, distributions or the proceeds of any such sale to pay any such tax or other governmental charge and the owner of such ADS will remain liable for any deficiency.

Transfer of American Depositary Shares 

The ADSs are transferable on the books of the depositary, provided that the depositary may close the transfer books (when other than in the ordinary course of business in consultation with us to the extent practicable) at any time, or from time to time, when deemed expedient by it in connection with the performance of its duties or at our written request. As a condition precedent to the execution and delivery, registration of transfer, split-up, combination or surrender of any ADS, the delivery of any distribution thereon, or withdrawal of any Deposited Securities, the Company, depositary, custodian or registrar may require payment from the owner of the ADS or the depositor of the shares of a sum sufficient to reimburse it for any tax or other governmental charge and any stock transfer, registration or conversion fee with respect thereto (including any such tax or charge and fee with respect to shares being deposited or withdrawn) and payment of any applicable fees payable by the holders of ADSs.

The depositary may refuse to effect the transfer of the ADSs, to register the transfer of any ADS or to make any distribution on, or related to, shares until it has received such proof of citizenship or residence, exchange control approval or other information as it may deem necessary or proper. The delivery, transfer, registration of transfer of outstanding ADSs and surrender of ADSs generally may be suspended or refused during any period when the transfer books of the depositary, the Company and the registrar are closed or if any such action is deemed necessary or advisable by the depositary or the Company, at any time or from time to time subject to the provisions of the deposit agreement. Notwithstanding anything in the deposit agreement to the contrary, the surrender of outstanding ADSs and the withdrawal of Deposited Securities may not be suspended except as permitted in General Instruction I(A)(1) to Form F-6 (as such form may be amended from time to time) under the Securities Act, which currently permits suspension only in connection with (i) temporary delays caused by closing the transfer books of the depositary or the Company or the deposit of shares in connection with voting at a shareholders’ meeting or the payment of dividends, (ii) the payment of fees, taxes and similar charges and (iii) compliance with any U.S. or foreign laws or governmental regulations relating to the ADSs or the withdrawal of the Deposited Securities. See “- Voting of Deposited Securities” with respect to additional transfer restrictions.

Acquisitions of ADSs 

Pursuant to the terms of the deposit agreement, all notifications and approvals required pursuant to our articles of association or under French law in connection with the acquisition of shares are applicable in all respects.

General 

Neither the depositary nor we, nor our respective directors, employees, agents or controlling persons (as defined under the Securities Act) will be liable to any owner or beneficial owner of ADSs if by reason of any provision of any present or future law or regulation of the United States, France or any other country, or of any other governmental or regulatory authority or stock exchange or by reason of any provision, present or future, of our articles of association, or by reason of any act of God or war or other circumstance beyond its or our control, the depositary or us or any of its or our directors, employees, agents or controlling persons (as defined under the Securities Act) shall be prevented, delayed or forbidden from, or be subject to any civil or criminal penalty on account of, doing or performing any act or thing which by the terms of the deposit agreement or the Deposited Securities it is provided will be done or performed; nor will we or the depositary incur any liability to any owner or beneficial owner of ADSs by reason of any nonperformance or delay, caused as aforesaid, in the performance of any act or thing which by the terms of the deposit agreement it is provided will or may be done or performed, or by reason of any exercise of, or failure to exercise, any discretion provided for under the deposit agreement or our articles of association.

We and the depositary assume no obligation, nor shall either we or the depositary be subject to any liability under the deposit agreement, except that each agrees to perform their respective obligations specifically set forth therein without negligence or bad faith.

The depositary will keep books at its Corporate Trust Office in the city of New York for the registration of transfers of ADSs, which at all reasonable times will be open for inspection by the owners of ADSs, provided that such inspection will not be for the purpose of communicating with owners in the interest of a business or object other than our business or a matter related to the deposit agreement or the ADSs.

The depositary may appoint one or more co-transfer agents for the purposes of effecting transfers, combinations and split-ups of ADSs at designated transfer offices on behalf of the depositary. In carrying out its functions, a
co-transfer agent may require evidence of authority and compliance with applicable laws and other requirements by owners or persons entitled to ADSs and will be entitled to protection and indemnity to the same extent as the depositary.

Governing Law 

The deposit agreement and the ADSs are governed by the laws of the State of New York.

SELLING SECURITYHOLDER

We have prepared this prospectus to allow the selling securityholder to offer and sell from time to time for its own account (i) Warrants to purchase up to 4,574,421 ordinary shares and (ii) up to 4,574,421 Warrant Shares, which may be in the form of ADSs, issuable upon the exercise of the 2,624,421 Warrants issued to EIB in connection with borrowings under Tranche A, and the estimated 1,100,000 Warrants and 850,000 Warrants to be issued to EIB in connection with borrowings under Tranche B and Tranche C respectively, pursuant to the Warrant Agreement.

We are registering the offer and sale of the Warrants and the Warrant Shares beneficially owned by the selling securityholder to satisfy our obligations to it pursuant to the Warrant Agreement. Pursuant to the Warrant Agreement, we have agreed to use our commercially reasonable efforts to keep the registration statement, of which this prospectus is a part, effective until the date on which all of the Warrants and the Warrant Shares issued or issuable upon exercise of the Warrants in the applicable Tranche(s) have been sold.

The following table sets forth (i) the name of the selling securityholder, (ii) the number of shares beneficially owned by the selling securityholder, including the Warrant Shares, (iii) the number of Warrant Shares that may be offered under this prospectus and (iv) the number of our ordinary shares beneficially owned by the selling securityholder assuming all of the Warrants or Warrant Shares covered hereby are sold.

The number of ordinary shares set forth in the following table for the selling securityholder reflects the exercise limitations as set forth in the Warrant Agreement. The Warrant Agreement provides that the holder of Warrants will not have the right to exercise any portion of its Warrants if such holder, together with its affiliates, would beneficially own in excess of 4.99% of the number of ordinary shares outstanding immediately after giving effect to such exercise (the “Beneficial Ownership Limitation”). By written notice to the Company, the holder may increase or decrease the Beneficial Ownership Limitation applicable to it to any other percentage specified in such notice; provided, however, that any such increase shall not be effective until the 61^st day after such notice is delivered to the Company. Accordingly, the number of ordinary shares set forth in the following table for the selling securityholder may exceed the number of ordinary shares that it could own beneficially at any given time as a result of its ownership of Warrant Shares. As a result, the actual number of Warrant Shares that may be issued to and sold by the selling securityholder could be materially less than the estimated numbers in the column titled “Number of Shares Being Offered” depending on factors which cannot be predicted by us at this time. In addition, we do not know how long the selling securityholder will hold the Warrants and Warrant Shares before selling them, and we currently have no agreements, arrangements or understandings with the selling securityholder regarding the sale or other disposition of any Warrants or Warrant Shares.

To our knowledge, the selling securityholder has not, nor has it during the three years prior to the date of this prospectus had, any position, office or other material relationships with us or any of our affiliates.

The information set forth in the table below is based upon information obtained from the selling securityholder. Beneficial ownership of the selling securityholder is determined in accordance with Rule 13d-3(d) under the Exchange Act. The percentage of shares beneficially owned after the offering is based on 37,481,986 ordinary shares outstanding as of March 25, 2026, and assuming the full exercise of the Warrants for 4,574,421 Warrant Shares.

As used in this prospectus, the term “selling securityholder” includes the selling securityholder listed in the table below, together with any additional selling securityholders listed in a prospectus supplement, and their donees, pledgees, assignees, transferees, distributees and successors-in-interest that receive Warrants or Warrant Shares in any non-sale transfer after the date of this prospectus. Unless otherwise indicated, the address for the selling securityholder is c/o EDAP Technomed Inc., 5321 Industrial Oaks Boulevard, Suite 110, Austin, Texas 78735.

(1)       Consists of Warrant Shares issuable upon exercise of the 2,624,421 Warrants issued to EIB in connection with borrowings under Tranche A and the estimated 1,100,000 Warrants and 850,000 Warrants to be issued to EIB in connection with borrowings under Tranche B and Tranche C respectively, pursuant to the Warrant Agreement. The Warrants issued to EIB are, and will, not become exercisable within sixty days of March 25, 2026. The principal business address of the EIB is 98-100 boulevard Konrad Adenauer L-2950 Luxembourg.

LIMITATIONS AFFECTING SHAREHOLDERS OF A FRENCH COMPANY

Ownership of ADSs or Shares by Non-French Residents (French Law)

Under French law, there is no limitation on the right of non-French residents or non-French security holders to own, or where applicable, vote securities of a French company.

Nevertheless, any investment: (i) by (a) any non-French citizen, (b) any French citizen not residing in France (within the meaning of Article 4 B of the French Tax Code), (c) any non-French entity or (d) any French entity controlled by one of the aforementioned individuals or entities; (ii) that will result in the relevant investor (a) acquiring control of an entity having its registered office in France or an establishment registered in France, (b) acquiring all or part of a business line of an entity having its registered office in France, (c) for non-EU or non-EEA investors crossing, directly or indirectly, alone or in concert, a 25% threshold of voting rights in an entity having its registered office in France, or (d) crossing, directly or indirectly, alone or in concert, the threshold of 10% of the voting rights of a company incorporated under French law whose shares are admitted to trading on a regulated market; and (iii) developing activities in certain strategic industries related to: (a) activities likely to prejudice national defense interests, participating in the exercise of official authority or likely to prejudice public order and public security (including activities related to weapons, dual-use goods and technologies, IT systems, cryptology, data capturing devices, gambling, toxic agents or data storage), (b) activities relating to essential infrastructure, goods or services (including energy, water, transportation, space, telecom, public health, farm products, media or extraction, processing and recycling of critical raw materials), and (c) research and development activities related to critical technologies (including cybersecurity, artificial intelligence, robotics, additive manufacturing, semiconductors, quantum technologies, energy storage, photonics, renewable energy technologies or biotechnology) or dual-use goods and technologies, is subject to the prior authorization of the French Minister of Economy, which authorization, if granted, may be subject to certain undertakings. The abovementioned (ii)(c) and (d) do not apply either to a natural person who is a national of a Member State of the European Union or of a State party to the Agreement on the European Economic Area that has concluded an administrative assistance agreement with France to combat fraud and tax evasion and who is domiciled in one of these States, or to an entity in which all the members of the control chain, within the meaning of II of Article R. 151-1 of the French Monetary and Financial Code, are governed by the law of one of these States or are nationals of and domiciled in one of these States.

A “fast track” procedure is available for investors whose holdings exceed the 10% threshold but are less than the 25% threshold mentioned above.

This request for prior authorization must be filed with the French Ministry of Economy, which has 30 business days from receipt of the complete file to provide a first decision that may (i) unconditionally authorize the investment or (ii) indicate that further examination is required. In the latter case, the French Ministry of Economy must make a second decision within 45 business days from its first decision. In case of lack of response from the French Ministry of Economy within the abovementioned timeframe, the authorization will be deemed refused. If the authorization is granted, it may be subject to the signature of a letter of undertakings aimed at protecting the French national interests. If an investment requiring the prior authorization of the French Minister of Economy is completed without such authorization having been granted, the French Minister of Economy might direct the relevant investor to (i) submit a request for authorization, (ii) have the previous situation restored at its own expense, or (iii) amend the investment. In the absence of such authorization, the relevant investment shall be deemed null and void. The relevant investor might also be found criminally liable and might be sanctioned with a fine that cannot exceed the greater of: (i) twice the amount of the relevant investment, (ii) 10% of the annual turnover before tax of the target company and (iii) €5 million (for a company) or €1 million (for an individual).

The French Monetary and Financial Code (“CMF”) provides for statistical reporting requirements. Transactions by which non-French residents acquire at least 10% of the share capital or voting rights, or cross the 10% threshold, of a French resident company, are considered as foreign direct investments in France and are subject to statistical reporting requirements (Articles R. 152-1; R.152-3 and R. 152-11 of the CMF). When the investment exceeds €15,000,000, companies must declare foreign transactions directly to the Banque de France within 20 business days following the date of certain direct foreign investments in us, including any purchase of ADSs. A failure to comply with such statistical reporting requirement may be sanctioned by five years’ imprisonment and a fine of a maximum amount equal to twice the amount that should have been reported, in accordance with Article L. 165-1 of the CMF. This amount may be increased fivefold if the violation is made by a legal entity.

PLAN OF DISTRIBUTION

The selling securityholder and any of its donees, pledgees, transferees, assignees and successors-in-interest may, from time to time, sell, transfer or otherwise dispose of any or all of its securities covered hereby on the Nasdaq Global Market or any other stock exchange, market or trading facility on which the securities are traded or in private transactions. These dispositions may be at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market price, at varying prices determined at the time of sale or at or negotiated prices. The selling securityholder may use any one or more of the following methods when disposing of securities:

The selling securityholder may, from time to time, pledge or grant a security interest in some or all of the securities owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the securities, from time to time, under this prospectus, or under an amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act, amending the list of selling securityholders to include the pledgee, transferee or other successors in interest as a selling securityholder under this prospectus. The selling securityholder also may transfer the securities in other circumstances, in which case the transferees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.

The selling securityholder may also sell securities under Rule 144 or any other exemption from registration under the Securities Act, if available, rather than under this prospectus.

Broker-dealers engaged by the selling securityholder may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the selling securityholder (or, if any broker-dealer acts as agent for the purchaser of securities, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this prospectus, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with Financial Industry Regulatory Authority (“FINRA”) Rule 2121; and in the case of a principal transaction a markup or markdown in compliance with FINRA IM 2121.01.

In connection with the sale of the securities or interests therein, the selling securityholder may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the securities in the course of hedging the positions they assume. The selling securityholder may also sell securities short and deliver these securities to close out their short positions, or loan or pledge the securities to broker-dealers that in turn may sell these securities. The selling securityholder may also enter into option or other transactions with broker-dealers or other financial institutions or create one or more derivative securities which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The selling securityholder and any broker-dealers or agents that are involved in selling the securities may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the securities purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. The selling securityholder has informed the Company that it does not have any written or oral agreement or understanding, directly or indirectly, with any person to distribute the securities.

The Company is required to pay certain fees and expenses incurred by the Company incident to the registration of the securities; provided, however, that the selling securityholder will pay all underwriting discounts and selling commissions, if any, and any related legal expenses incurred by it. The Company has agreed to indemnify the selling securityholder against certain losses, claims, damages and liabilities, including liabilities under the Securities Act. The selling securityholder may indemnify any broker-dealer that participates in transactions involving the sale of the shares against certain liabilities arising under the Securities Act.

We agreed to use commercially reasonable efforts to keep this prospectus effective until the date on which all of the Warrants and the Warrant Shares issued or issuable upon exercise of the Warrants in the applicable Tranche(s) have been sold. The resale securities will be sold only through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the resale securities covered hereby may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the resale securities may not simultaneously engage in market making activities with respect to the ordinary shares for the applicable restricted period, as defined in Regulation M, prior to the commencement of the distribution. In addition, the selling securityholder will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of the ordinary shares by the selling securityholder or any other person. We will make copies of this prospectus available to the selling securityholder and have informed them of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act).

ENFORCEability OF CIVIL LIABILITIES

We are a société anonyme, or limited liability corporation, organized under the laws of the Republic of France. Some of our directors and executive officers reside in the Republic of France. In addition, a substantial portion of our assets is located outside of the United States. As a result, it may be difficult for investors:

Nevertheless, a final judgment for the payment of money rendered by any federal or state court in the United States based on civil liability, whether or not predicated solely upon the U.S. federal securities laws, would be recognized and enforced in France provided that a French judge considers that this judgment meets the French legal requirement concerning the recognition and the enforcement of foreign judgments and is capable of being immediately enforced in the United States. A French court is therefore likely to grant the enforcement of a foreign judgment without a review of the merits of the underlying claim, only if (i) that judgment was rendered by a court having jurisdiction over the matter as the dispute is clearly connected to the jurisdiction of such court, the choice of the U.S. court was not fraudulent and the French courts did not have exclusive jurisdiction over the matter, (ii) the judgment does not contravene international public policy rules, as applied by French courts, whether such rules pertain to the merits or to the procedure of the case, including any defense rights, (iii) the judgment is not tainted with fraud and (iv) the judgment does not conflict with a French judgment or a foreign judgment (or an arbitral award) which has become effective in France. In addition, French law guarantees full compensation for the harm suffered but is limited to the actual damages, so the victim does not suffer or benefit from the situation, it being specified that under French law, the principle of awarding punitive damages is not, per se, contrary to public order, provided the amount awarded is not disproportionate to the harm suffered and the defendant’s breach.

As a result, the enforcement, by U.S. investors, of any judgments obtained in U.S. courts in civil and commercial matters, including judgments under the U.S. federal securities law against us or members of our Board of Directors, officers or certain experts named herein who are residents of France or countries other than the United States would be subject to the above conditions.

Finally, there may be doubt as to whether a French court would impose civil liability on us, the members of our Board of Directors, our officers or certain experts named herein in an original action predicated solely upon the U.S. federal securities laws brought in a court of competent jurisdiction in France against us or such members, officers or experts, respectively.

TAXATION

Certain Material U.S. Federal Income Tax Considerations

The following discussion describes certain material U.S. federal income tax considerations applicable to U.S. holders (as defined below) relating to (i) the ownership and disposition of ordinary shares or ADSs, including ordinary shares or ADSs acquired upon exercise of Warrants, and (ii) the exercise, disposition and lapse of Warrants. This summary applies to U.S. holders that hold our ordinary shares, ADSs or Warrants as capital assets. This summary is based on the Internal Revenue Code (the “Code”), U.S. Treasury regulations promulgated thereunder and administrative and judicial interpretations thereof, all as in effect on the date hereof and all of which are subject to change, possibly with retroactive effect. This discussion does not address all of the U.S. federal income tax considerations that may be relevant to specific U.S. holders in light of their particular circumstances, or to U.S. holders subject to special treatment under U.S. federal income tax laws (such as certain financial institutions, insurance companies, broker-dealers and traders in securities or other persons that generally mark their securities to market for U.S. federal income tax purposes, tax-exempt entities, retirement plans, regulated investment companies, real estate investment trusts, certain former citizens, expatriates or long-term residents of the United States, persons that hold ordinary shares, ADSs or Warrants as part of a “straddle,” “hedge,” “conversion transaction,” “synthetic security” or integrated investment, persons deemed to sell our ordinary shares, ADSs or Warrants under the constructive sale provisions of the Code, persons who hold or receive our ordinary shares, ADSs or Warrants pursuant to the exercise of any employee stock option or otherwise as compensation, persons that have a “functional currency” other than the U.S. dollar, persons that own directly, indirectly or through attribution 10% or more of the voting power or value of our ordinary shares or ADSs, corporations that accumulate earnings to avoid U.S. federal income tax, partnerships and other pass-through entities (or arrangements treated as a partnership for U.S. federal income tax purposes), and investors in such pass-through entities). This summary does not address any U.S. state or local tax consequences, non-U.S. tax consequences or any U.S. federal estate, gift or alternative minimum tax consequences, the application of special tax accounting rules under Section 451(b) of the Code or the Medicare contribution tax on net investment income.

As used in this discussion, the term “U.S. holder” means a beneficial owner of ordinary shares, ADSs or Warrants that is, for U.S. federal income tax purposes, or is treated as: (1) an individual who is a citizen or resident of the United States, (2) a corporation created or organized in or under the laws of the United States, any state thereof, or the District of Columbia, (3) an estate the income of which is subject to U.S. federal income tax regardless of its source or (4) a trust (x) with respect to which a court within the United States is able to exercise primary supervision over its administration and one or more United States persons have the authority to control all of its substantial decisions or (y) that has elected under applicable U.S. Treasury regulations to be treated as a domestic trust for U.S. federal income tax purposes.

If an entity or arrangement treated as a partnership for U.S. federal income tax purposes holds ordinary shares, ADSs or Warrants, the U.S. federal income tax consequences relating to an investment in ordinary shares, ADSs or Warrants will depend in part upon the status and activities of such entity or arrangement and the particular partner. Any such entity or arrangement and a partner of any such entity should consult its tax advisor regarding the U.S. federal income tax consequences applicable to it (and, as applicable, its partners) of the purchase, ownership and disposition of ordinary shares, ADSs or Warrants.

Persons considering an investment in ordinary shares, ADSs or Warrants should consult their tax advisors as to the particular tax consequences applicable to them relating to the purchase, ownership and disposition of ordinary shares, ADSs or Warrants, including the applicability of U.S. federal, state and local tax laws and non-U.S. tax laws.

The discussion below assumes that the representations contained in the deposit agreement are true and that the obligations in the deposit agreement and any related agreement will be complied with in accordance with their terms. Generally, a holder of an ADS should be treated for U.S. federal income tax purposes as the beneficial owner of the ordinary shares represented by the ADS. Accordingly, no gain or loss will be recognized upon an exchange of ADSs for ordinary shares. The U.S. Treasury has expressed concerns that intermediaries in the chain of ownership between the holder of an ADS and the issuer of the security underlying the ADS may be taking actions that are inconsistent with the beneficial ownership by the holder of the underlying security. Accordingly, the creditability of foreign taxes, if any, as described below, could be affected by actions taken by intermediaries in the chain of ownership between the holders of ADSs and our company if as a result of such actions the holders of ADSs are not properly treated as beneficial owners of the underlying ordinary shares.

Exercise or lapse of Warrants

A U.S. holder generally will not recognize gain or loss upon the acquisition of ordinary shares or ADSs on the exercise of a Warrant for cash. A U.S. holder’s tax basis in ordinary shares or ADSs received upon exercise of the Warrant should be an amount equal to the sum of the U.S. holder’s tax basis in the Warrant exercised therefor and the exercise price. The U.S. holder’s holding period for ordinary shares or ADSs received upon exercise of the Warrant will begin on the date following the date of exercise (or possibly the date of exercise) of the Warrant and will not include the period during which the U.S. holder held the Warrant. If a Warrant is allowed to lapse unexercised, a U.S. holder that has otherwise received no proceeds with respect to such Warrant generally will recognize a capital loss equal to such U.S. holder’s tax basis in the Warrant. Deductions for capital losses are subject to significant limitations under the Code.

Dispositions of Warrants

Subject to the rules discussed below under “—Passive foreign investment company consequences”, a U.S. holder generally will recognize gain or loss on any sale, exchange, redemption or other taxable disposition of Warrants in an amount equal to the difference between (i) the U.S. dollar value of cash received plus the fair market value of any property received and (ii) such U.S. holder’s adjusted tax basis in such Warrants. Any gain or loss recognized by a U.S. holder on a taxable disposition of Warrants generally will be capital gain or loss. A U.S. holder’s tax basis in Warrants generally will be determined initially by the holder’s U.S. dollar cost for the Warrants (subject to any adjustments provided under the rules described below under “—Passive foreign investment company consequences”). Subject again to the rules below under “—Passive foreign investment company consequences”, such capital gain or loss generally will be long-term capital gain taxable at a reduced rate for non-corporate U.S. holders, or long-term capital loss if, on the date of sale or other taxable disposition, the Warrants were held by the U.S. holder for more than one year. Any capital gain of a non-corporate U.S. holder that is not long-term capital gain is taxed at ordinary income rates. The deductibility of capital losses is subject to limitations. Any gain or loss recognized from the sale or other disposition of the Warrants will generally be gain or loss from sources within the United States for U.S. foreign tax credit purposes.

Certain adjustments to the Warrants

The terms of each Warrant provide for an adjustment to the number of ordinary shares or ADSs for which the Warrant may be exercised or to the exercise price of the Warrant in certain events. An adjustment which has the effect of preventing dilution generally is not taxable. A U.S. holder of a Warrant would, however, be treated as receiving a constructive distribution from us if, for example, the adjustment increases the holder’s proportionate interest in our assets or earnings and profits (for instance, through an increase in the number of ordinary shares or ADSs that would be obtained upon exercise of such Warrant) as a result of a distribution of cash or other property such as other securities to the holders of the ordinary shares or ADSs which is taxable to the U.S. holders of such shares.

Passive foreign investment company consequences

In general, a corporation organized outside the United States will be treated as a passive foreign investment company (“PFIC”), for any taxable year in which, after applying certain look-through rules, either (1) at least 75% of its gross income is “passive income”, or (2) on average at least 50% of the value of its assets, determined on the basis of a quarterly average, are assets that produce passive income or are held for the production of passive income. Passive income for this purpose generally includes, among other things, dividends, interest, certain royalties, rents, and gains from the sale or exchange of property that gives rise to passive income. Assets that produce or are held for the production of passive income generally include cash, even if held as working capital or raised in a public offering, marketable securities, and other assets that may produce passive income. Generally, in determining whether a non-U.S. corporation is a PFIC, a proportionate share of the income and assets of each corporation in which it owns, directly or indirectly, at least a 25% interest (by value) is taken into account.

Our status as a PFIC will depend on the nature and composition of our gross income, and the nature, composition and value of our gross assets from time to time. We have not yet determined whether we expect to be a PFIC for the current taxable year. Based on the nature of our gross income and the estimated value and composition of our gross assets, we believe that we were not a PFIC during the taxable year ended December 31, 2025. Because we may hold a substantial amount of cash and cash equivalents, and because the calculation of the value of our assets may be based in part on the value of our ADSs or ordinary shares, which may fluctuate considerably, we may be a PFIC in the current taxable year or future taxable years. Even if we determine that we are not a PFIC for a taxable year, there can be no assurance that the Internal Revenue Service (the “IRS”) will agree with our conclusion or would not successfully challenge our position. Our status as a PFIC is a fact-intensive determination made on an annual basis applying principles and methodologies that are unclear in some respects and subject to varying interpretations. In particular, the characterization of our assets as active or passive may depend in part on our current and intended future business plans, which are subject to change. Accordingly, we cannot provide any assurance, and our U.S. counsel expresses no opinion with respect to our PFIC status for any prior, current or future taxable year.

If we are a PFIC in any taxable year during which a U.S. holder owns ordinary shares, ADSs or Warrants, the U.S. holder could be liable for additional taxes and interest charges under the “PFIC excess distribution regime” upon (1) a distribution paid during a taxable year that is greater than 125% of the average annual distributions paid in the three preceding taxable years, or, if shorter, the U.S. holder’s holding period for the ordinary shares, ADSs or Warrants, and (2) any gain recognized on a sale, exchange or other disposition, including a pledge, of the ordinary shares, ADSs or Warrants, whether or not we continue to be a PFIC. Under the PFIC excess distribution regime, the tax on such distribution or gain would be determined by allocating the distribution or gain ratably over the U.S. holder’s holding period for the ordinary shares, ADSs or Warrants. The amount allocated to the current taxable year (i.e., the year in which the distribution occurs or the gain is recognized) and any year prior to the first taxable year in which we are a PFIC will be taxed as ordinary income earned in the current taxable year. The amount allocated to other taxable years will be taxed at the highest marginal rates in effect for individuals or corporations, as applicable, to ordinary income for each such taxable year, and an interest charge, generally applicable to underpayments of tax, will be added to the tax.

If we are a PFIC for any year during which a U.S. holder holds ordinary shares or ADSs, we generally must continue to be treated as a PFIC by that holder for all succeeding years during which the U.S. holder holds the ordinary shares or ADSs, unless we cease to meet the requirements for PFIC status and the U.S. holder makes a “deemed sale” election with respect to the ordinary shares or ADSs. If the election is made, the U.S. holder will be deemed to sell the ordinary shares or ADSs it holds at their fair market value on the last day of the last taxable year in which we qualified as a PFIC, which may result in recognition of gain (but not loss) taxable under the PFIC excess distribution regime without the receipt of any corresponding cash. After the deemed sale election, the U.S. holder’s ordinary shares or ADSs would not be treated as shares of a PFIC unless we subsequently again become a PFIC.

If we are a PFIC for any taxable year during which a U.S. holder holds ordinary shares or ADSs and one of our subsidiaries or other entity in which we held a direct or indirect equity interest is also a PFIC (i.e., a lower-tier PFIC), such U.S. holder would be treated as owning a proportionate amount (by value) of the shares of the lower-tier PFIC and would be subject to U.S. federal income tax under the PFIC excess distribution regime on certain distributions by the lower-tier PFIC and on gain from the disposition of shares of the lower-tier PFIC even though such U.S. holder would not receive the proceeds of those distributions or dispositions. Each U.S. holder is advised to consult its tax advisors regarding the application of the PFIC rules to our non-U.S. subsidiaries.

If we are a PFIC, a U.S. holder will not be subject to tax under the PFIC excess distribution regime on distributions or gain recognized on ordinary shares or ADSs if such U.S. holder makes a valid “mark-to-market” election for our ordinary shares or ADSs. A mark-to-market election is available to a U.S. holder only for “marketable stock.” Our ordinary shares or ADSs will be marketable stock as long as they remain listed on the Nasdaq Global Market or other “qualified exchange” and are regularly traded, other than in de minimis quantities, on at least 15 days during each calendar quarter. If a mark-to-market election is in effect, a U.S. holder generally would take into account, as ordinary income each year, the excess of the fair market value of the ordinary shares or ADSs held at the end of such taxable year over the adjusted tax basis of such ordinary shares or ADSs. The U.S. holder also would take into account, as an ordinary loss each year, the excess of the adjusted tax basis of such ordinary shares or ADSs over their fair market value at the end of the taxable year, but only to the extent of the excess of amounts previously included in income over ordinary losses deducted as a result of the mark-to-market election. The U.S. holder’s tax basis in ordinary shares or ADSs would be adjusted to reflect any income or loss recognized as a result of the mark-to-market election. Any gain from a sale, exchange or other disposition of ordinary shares or ADSs in any taxable year in which we are a PFIC would be treated as ordinary income and any loss from such sale, exchange or other disposition would be treated first as ordinary loss (to the extent of any net mark-to-market gains previously included in income) and thereafter as capital loss. If, after having been a PFIC for one or more taxable years, we cease to be classified as a PFIC for the remainder of a U.S. holder’s holding period in ordinary shares or ADSs, the U.S. holder would not be required to take into account any unrecognized gain or loss in the manner described above and any subsequently recognized gain or loss would be subject to tax as described below “—Sale or Other Disposition of Ordinary Shares or ADSs.”

A mark-to-market election will not apply to ordinary shares or ADSs for any taxable year during which we are not a PFIC, but will remain in effect with respect to any subsequent taxable year in which we become a PFIC. Such election will not apply to our subsidiaries. Accordingly, a U.S. holder may continue to be subject to tax under the PFIC excess distribution regime with respect to any lower-tier PFICs notwithstanding the U.S. holder’s mark-to-market election for the ordinary shares or ADSs.

The tax consequences that would apply if we are a PFIC also would be different from those described above if a U.S. holder were able to make a valid qualified electing fund (“QEF”) election. For any taxable year in which we are a PFIC, we will determine whether we will provide to U.S. holders the information required to make a QEF election. However, there is no assurance that such information will be provided, and prospective investors should not assume that a QEF election will be available.

Under proposed Treasury Regulations, if a U.S. Holder has an option, warrant or other right to acquire stock of a PFIC (such as a Warrant), such option, warrant or right is generally considered to be PFIC stock subject to the default rules of Section 1291 of the Code. This rule could adversely affect the availability of the QEF election and mark-to-market election with respect to ordinary shares acquired on exercise of Warrants. It is not entirely clear how various aspects of the PFIC rules would apply to the Warrants, and U.S. holders should consult their own tax advisors regarding the application of the PFIC rules to Warrants and ordinary shares acquired upon exercise of Warrants.

Each U.S. person that is a shareholder of a PFIC is generally required to file an annual information return on IRS Form 8621 containing such information as the U.S. Treasury Department may require. The failure to file IRS Form 8621 could result in the imposition of penalties and the extension of the statute of limitations with respect to U.S. federal income tax.

The U.S. federal income tax rules relating to PFICs are very complex. Prospective U.S. holders are strongly urged to consult their tax advisors with respect to the impact of PFIC status on the purchase, ownership and disposition of ordinary shares, ADSs or Warrants, the consequences to them of an investment in a PFIC, any elections available with respect to the ordinary shares, ADSs or Warrants and the IRS information reporting obligations with respect to the purchase, ownership and disposition of the ordinary shares, ADSs or Warrants.

Distributions

We currently do not expect to make distributions on our ordinary shares or ADSs. Subject to the discussion above under “—Passive foreign investment company consequences,” a U.S. holder that receives a distribution with respect to ordinary shares or ADSs generally will be required to include the gross amount of such distribution (including the full amount of any French withholding tax on such amount) in gross income as a dividend when actually or constructively received to the extent of the U.S. holder’s pro rata share of our current and/or accumulated earnings and profits (as determined under U.S. federal income tax principles). To the extent a distribution received by a U.S. holder is not a dividend because it exceeds the U.S. holder’s pro rata share of our current and accumulated earnings and profits, it will be treated first as a tax-free return of capital and reduce (but not below zero) the adjusted tax basis of the U.S. holder’s ordinary shares or ADSs. To the extent the distribution exceeds the adjusted tax basis of the U.S. holder’s ordinary shares or ADSs, the remainder will be taxed as capital gain. Because we do not expect to account for our earnings and profits in accordance with U.S. federal income tax principles, U.S. holders should expect all distributions to be reported to them as dividends. Distributions on ordinary shares or ADSs that are treated as dividends generally will constitute income from sources outside the United States for foreign tax credit purposes and generally will constitute passive category income. If any foreign withholding tax is imposed on dividends paid on ordinary shares or ADSs, U.S. holders may be eligible for a foreign tax credit against such U.S. holder’s federal income tax liability, or an itemized deduction in lieu of a foreign tax credit. Such dividends will not be eligible for the “dividends received” deduction generally allowed to corporate shareholders with respect to dividends received from U.S. corporations.

Dividends paid by a “qualified foreign corporation” are eligible under current law for taxation at a reduced capital gains rate rather than the marginal tax rates generally applicable to ordinary income provided that certain requirements are met. A non-U.S. corporation (other than a corporation that is classified as a PFIC with respect to the U.S. holder for the taxable year in which the dividend is paid or the preceding taxable year) generally will be considered to be a qualified foreign corporation (a) if it is eligible for the benefits of a comprehensive tax treaty with the United States that the Secretary of Treasury of the United States determines is satisfactory for this purpose and that includes an exchange of information provision, or (b) with respect to any dividend it pays on shares that are readily tradable on an established securities market in the United States. We believe that the Company qualifies as a resident of France for purposes of, and are eligible for the benefits of, the Convention between the Government of the United States of America and the Government of the French Republic for the Avoidance of Double and the Prevention of Fiscal Evasion with respect to Taxes on Income and Capital, signed January 1, 1996, as amended and currently in force (the “Convention Treaty”). We also believe that the Convention Treaty should be treated as satisfying conditions described in clause (a) above, although there can be no assurance in this regard. Further, our ordinary shares or ADSs will be listed on the Nasdaq Global Market, which is an established securities market in the United States, and we expect the ordinary shares or ADSs to be readily tradable on the Nasdaq Global Market, although there can be no assurance in this regard. Subject to the discussion above under “—Passive foreign investment company consequences,” if the Convention Treaty is applicable, or if the ordinary shares or ADSs are readily tradable on an established securities market in the United States, dividends paid on ordinary shares or ADSs generally will be “qualified dividend income” in the hands of individual U.S. holders, provided that certain conditions are met, including certain holding period requirements and the absence of certain risk reduction transactions. Each U.S. holder is urged to consult its tax advisors regarding the availability of the reduced tax rate on dividends with regard to its particular circumstances.

Sale or other taxable disposition of Ordinary Shares or ADSs

Subject to the discussion above under “—Passive foreign investment company consequences,” a U.S. holder generally will recognize capital gain or loss for U.S. federal income tax purposes upon the sale or other taxable disposition of ordinary shares or ADSs in an amount equal to the difference, if any, between the amount realized (i.e., the amount of cash plus the fair market value of any property received) on the sale, exchange or other disposition and such U.S. holder’s adjusted tax basis in the ordinary shares or ADSs. Such capital gain or loss generally will be long-term capital gain taxable at a reduced rate for non-corporate U.S. holders, or long-term capital loss if, on the date of sale or other taxable disposition, the ordinary shares or ADSs were held by the U.S. holder for more than one year. Any capital gain of a non-corporate U.S. holder that is not long-term capital gain is taxed at ordinary income rates. The deductibility of capital losses is subject to limitations. Any gain or loss recognized from the sale or other disposition of ordinary shares or ADSs will generally be gain or loss from sources within the United States for U.S. foreign tax credit purposes.

Information reporting and backup withholding

U.S. holders may be required to file certain U.S. information reporting returns with the IRS with respect to an investment in ordinary shares, ADSs or Warrants, including, among others, IRS Form 8938 (Statement of Specified Foreign Financial Assets). As described above under “—Passive foreign investment company consequences”, each U.S. holder who is a shareholder of a PFIC must file an annual report containing certain information.

Dividends on and proceeds from the sale or other disposition of ordinary shares, ADSs or Warrants may be reported to the IRS unless the U.S. holder establishes a basis for exemption. Backup withholding may apply to amounts subject to reporting if the U.S. holder fails to provide an accurate U.S. taxpayer identification number or otherwise establish a basis for exemption, or is described in certain other categories of persons. However, U.S. holders that are corporations generally are excluded from these information reporting and backup withholding tax rules. Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules generally will be allowed as a refund or a credit against a U.S. holder’s U.S. federal income tax liability if the required information is furnished by the U.S. holder on a timely basis to the IRS.

U.S. holders should consult their tax advisors regarding the backup withholding tax and information reporting rules.

THIS SUMMARY OF CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS IS FOR GENERAL INFORMATION ONLY AND IS NOT TAX ADVICE. YOU SHOULD CONSULT YOUR TAX ADVISOR WITH RESPECT TO THE APPLICATION OF U.S. FEDERAL INCOME TAX LAWS TO YOUR PARTICULAR SITUATION AS WELL AS ANY TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP, AND DISPOSITION OF ORDINARY SHARES, ADSs OR WARRANTS ARISING UNDER U.S. FEDERAL ESTATE OR GIFT TAX RULES OR UNDER THE LAWS OF ANY STATE, LOCAL, NON-U.S. OR ANY OTHER TAXING JURISDICTION.

THE DISCUSSION ABOVE IS A GENERAL SUMMARY. IT DOES NOT COVER ALL TAX MATTERS THAT MAY BE OF IMPORTANCE TO A PROSPECTIVE INVESTOR. EACH PROSPECTIVE INVESTOR IS URGED TO CONSULT ITS OWN TAX ADVISOR ABOUT THE TAX CONSEQUENCES TO IT OF AN INVESTMENT IN ORDINARY SHARES, ADSS OR WARRANTS IN LIGHT OF THE INVESTOR’S OWN CIRCUMSTANCES.

Material French Income Tax Considerations

The following describes the material French income tax consequences to U.S. holders of purchasing, owning and disposing of our warrants, ordinary shares or ADSs and, unless otherwise noted, this discussion is the opinion of our French counsel, insofar as it relates to matters of French tax law and legal conclusions with respect to those matters.

This discussion does not purport to be a complete analysis or listing of all potential tax effects of the acquisition, ownership or disposition of our warrants, ordinary shares or ADSs to any particular investor, and does not discuss tax considerations that arise from rules of general application or that are generally assumed to be known by investors. All of the following is subject to change. Such changes could apply retroactively and could affect the consequences described below.

The description of the French income tax and real estate wealth tax consequences set forth below is based on the Convention between the Government of the United States of America and the Government of the French Republic for the Avoidance of Double Taxation and the Prevention of Fiscal Evasion with Respect to Taxes on Income and Capital of August 31, 1994 (the “Treaty”), which came into force on December 30, 1995 (as amended by any subsequent protocols, including the protocol of January 13, 2009), and the tax guidelines issued by the French tax authorities in force as of the date of this prospectus, or the Treaty.

If a partnership (or any other entity treated as a partnership for U.S. federal income tax purposes) holds warrants, ordinary shares or ADSs, the tax treatment of the partnership and a partner in such partnership generally will depend upon the status of the partner and the activities of the partnership. Such partner or partnership is urged to consult its own tax advisor regarding the specific tax consequences of acquiring, owning and disposing of ordinary shares or ADSs.

French tax rules applicable to French assets that are held by or in foreign trusts provide inter alia for the inclusion of trust assets in the settlor’s net assets for the purpose of applying the French real estate wealth tax, for the application of French gift and death duties to French assets held in trust, for a specific tax on capital on the French assets of foreign trusts not already subject to the French real estate wealth tax and for a number of French tax reporting and disclosure obligations. The following discussion does not address the French tax consequences applicable to securities (including warrants, ordinary shares or ADSs) held in trusts. If warrants, ordinary shares or ADSs are held in trust, the grantor, trustee and beneficiary are urged to consult their own tax advisor regarding the specific tax consequences of acquiring, owning and disposing of securities (including ordinary shares or ADSs).

This discussion applies only to investors that hold warrants, ordinary shares or ADSs as capital assets, that have the U.S. dollar as their functional currency, that are entitled to Treaty benefits under the “Limitation on Benefits” provision contained in the Treaty, and whose ownership of the warrants, ordinary shares or ADSs is not effectively connected to a permanent establishment or a fixed base in France. Certain U.S. holders (including, but not limited to, U.S. expatriates, partnerships or other entities classified as partnerships for U.S. federal income tax purposes, banks, insurance companies, regulated investment companies, tax-exempt organizations, financial institutions, persons subject to the alternative minimum tax, persons who acquired the securities pursuant to the exercise of employee share options or otherwise as compensation, persons that own (directly, indirectly or by attribution) 5% or more of our voting stock or 5% or more of our outstanding share capital, dealers in securities or currencies, persons that elect to mark their securities to market for U.S. federal income tax purposes and persons holding securities as a position in a synthetic security, straddle or conversion transaction) may be subject to special rules not discussed below.

U.S. holders are urged to consult their own tax advisors regarding the tax consequences of the purchase, ownership and disposition of securities in light of their particular circumstances, especially with regard to the “Limitations on Benefits” provision.

Estate and Gift Taxes

In general, a transfer of securities by gift or by reason of death of a U.S. holder that would otherwise be subject to French gift or inheritance tax, respectively, will not be subject to such French tax by reason of the Convention between the Government of the United States of America and the Government of the French Republic for the Avoidance of Double Taxation and the Prevention of Fiscal Evasion with Respect to Taxes on Estates, Inheritances and Gifts, dated November 24, 1978 (as amended by the protocol of December 8, 2004), unless (i) the donor or the transferor is domiciled in France at the time of making the gift or at the time of his or her death, or (ii) the securities were used in, or held for use in, the conduct of a business through a permanent establishment or a fixed base in France.

Tax on Financial Transactions

Pursuant to Article 235 ter ZD of the Code général des impôts (the “French Tax Code” or “FTC”), purchases of certain securities, including warrants, ordinary shares or ADSs, issued by a French company listed on a regulated market of the European Union or on a foreign regulated market formally acknowledged by the French Minister of Economy, after consultation opinion from the French Financial Markets Authority (AMF) are subject to a 0.4% French tax on financial transactions provided that the issuer’s market capitalization exceeds 1 billion euros as of December 1 of the year preceding the taxation year (the rate of the French tax on financial transactions was raised from 0.3% to 0.4% for the acquisitions made as from April 1 2025). A list of French relevant companies whose market capitalization exceeds 1 billion euros as of December 1 of the year preceding the taxation year is published annually and at least once a year, by the French State. Pursuant to Regulations BOI-ANNX-000467-20251217 issued on December 17, 2025, as at December 1, 2025, our market capitalization did not exceed 1 billion euros and are therefore not included in such list. In addition, the Nasdaq Global Market is not currently acknowledged by the French Minister of Economy but this may change in the future.

As a consequence, neither the warrants, the ADSs nor the ordinary shares are currently within the scope of the French tax on financial transactions.

Following this offering, purchases of our securities may be subject to such tax in the future provided that our market capitalization exceeds 1 billion euros in the year preceding the taxation year and that the Nasdaq Global Market is acknowledged by the French Minister of Economy.

Registration Duties

In the case where the French tax on financial transactions provided for under Article 235 ter ZD of the FTC is not applicable, transfers of shares issued by a French company, which is listed on a regulated or organized market within the meaning of the French Monetary and Financial Code (Code monétaire et financier), are subject to uncapped registration duties at the rate of 0.1% if the transfer is evidenced by a written statement (“acte”) executed either in France or outside France. Although there is no case law or official guidelines published by the French tax authorities on this point, transfers of ADSs and warrants should remain outside of the scope of the aforementioned 0.1% registration duties.

 Exercise of warrants

As a matter of principle, under French tax law, a U.S. holder generally will not recognize gain or loss upon the acquisition of ordinary shares or ADSs on the exercise of a warrant for cash.

Tax on Sale or Other Disposition

As a matter of principle, under French tax law, a U.S. holder should not be subject to any French tax on any capital gain from the sale, exchange, repurchase or redemption by us of warrants, ordinary shares or ADSs (it being however specified as regards redemption that redemption proceeds may under certain circumstances be partially or fully qualified as dividends for French domestic tax law and, as a result, be subject to French dividend withholding tax), provided, regarding ordinary shares or ADS, that such U.S. holder is not a French tax resident for French tax purposes, and has not held more than 25% of our dividend rights, known as “droits aux bénéfices sociaux” at any time during the preceding five years, either directly or indirectly.

As an exception, a U.S holder resident, established or incorporated in a non-cooperative State or territory as defined in Article 238-0 A of the FTC other than those States or territories mentioned in 2° of 2 bis of the same Article 238-0 A should be subject to a 75% withholding tax in France on any such capital gain, regardless of the fraction of the dividend rights it holds. The list of non-cooperative State or territories is published by decree and is in principal updated annually. This list was last updated on April 18, 2025, and currently includes Anguilla, Antigua and Barbuda, Turks and Caicos Islands, Vanuatu, Fiji, Guam, the US Virgin Islands, Palau, Panama, Russia, Samoa, American Samoa and Trinidad and Tobago. States referred to in Article 238-0 A 2 bis 2° of the Code général des impôts, and thus outside of the scope of Article 244 bis B of the Code général des impôts, are currently Fiji, Guam, US Virgin Islands, Palau, Panama, Russia, Samoa, American Samoa and Trinidad and Tobago.

In general, under application of the Treaty, a U.S. holder who is a U.S. resident for purposes of the Treaty and entitled to Treaty benefit will not be subject to French tax on any such capital gain (other than redemption proceeds characterized as dividends under French domestic tax law or administrative guidelines) unless the warrants, ordinary shares or the ADSs form part of the business property of a permanent establishment or fixed base that the U.S. holder has in France. U.S. holders who own warrants, ordinary shares or ADSs through U.S. partnerships that are not resident for Treaty purposes are advised to consult their own tax advisors regarding their French tax treatment and their eligibility for Treaty benefits in light of their own particular circumstances.

A U.S. holder that is not a U.S. resident for Treaty purposes or is not entitled to Treaty benefit (and in both cases is not resident, established or incorporated in a non-cooperative State or territory as defined in Article 238-0 A of the FTC other than those States or territories mentioned in 2° of 2 bis of the same Article 238-0 A) and has held more than 25% of our dividend rights, known as “droits aux bénéfices sociaux,” at any time during the preceding five years, either directly or indirectly, and, as relates to individuals, alone or with relatives will be subject to a levy in France at the rate of 12.8% if such U.S. holder is an individual or 25% for corporate bodies or other legal entities.

Please note that for non-French tax resident entity that holds more than 25% of dividends rights and may be subject to French tax on capital gains, the Amended Finance Bill for 2021 dated July 19, 2021 (published July 20, 2021) amended the provisions of Article 244 bis B of the FTC in order to comply with European Union law as French courts ruled that the provisions of article 244 bis B of the FTC do not comply with European principles and can therefore not be applied by the French tax authorities to base a French taxation of a foreign shareholder. The Amended Finance Bill for 2021 provides for a refund mechanism allowing, for transfers occurring from June 30, 2021, eligible non-French tax resident corporate investors to claim a refund of the non-resident French capital gains tax to the extent such tax exceeds the amount that would have been due under French corporate income tax if they had been French tax residents (French Administrative Supreme Court, December 22, 2022, n°447568, Sté Runa Capital Fund I LP). This refund mechanism is available to entities established (i) in an EU Member State or a Member State of the European Economic Area, other than a non-cooperative State or Territory within the meaning of Article 238-0 A of the FTC that has concluded a tax treaty with France that includes an administrative assistance provision to combat tax fraud and tax evasion and (ii) a state, other than a non-cooperative States or Territories that has concluded a tax treaty with France that includes an administrative assistance clause regarding the exchange of information aimed at combating tax fraud and tax evasion, provided that the transferor is not effectively involved in the management or control of the entity whose shares are disposed of or redeemed. In addition, the Amended Finance Bill provides that specific collective investment funds established in an EU Member State or a Member State of the European Economic Area, or in a third State, other than a non-cooperative States or Territories, that have concluded a treaty with France that has an administrative assistance provision aimed at combating tax fraud and tax evasion, are excluded from the scope of the above-mentioned nonresident capital gain taxation under certain conditions.

In addition and for non-French tax resident individual that holds more than 25% of our dividends rights and may be subject to French tax on capital gains, the Finance Bill for 2025 dated February 14, 2025 (published February 15, 2025) also amended the provisions of Article 244 bis B of the FTC in order to comply with European Union law as French courts ruled that non-French tax resident individuals can, upon claim, request the refund of the portion of the French personal income tax that exceeds the French personal income tax they would have been liable for if they had been French tax resident and had elected for the progressive income tax scale, benefiting, where applicable, from allowances for length of ownership (French Administrative Supreme Court, May 31, 2024, n° 489370). This refund mechanism is available for claim made from November 22, 2024.

Special rules apply to U.S. holders who are residents of more than one country.

Taxation of Dividends

Dividends paid by a French corporation to beneficial owners that are non-residents of France are generally subject to French withholding tax at a rate of 12.8% when the recipient is an individual and 25% otherwise. Dividends paid by a French corporation in a non-cooperative State or territory, as defined in Article 238-0 A of the FTC other than those States or territories mentioned in 2° of 2 bis of the same Article 238-0 A, may be subject to French withholding tax at a rate of 75%. However, eligible U.S. holders, other than individuals subject to the French withholding tax at a rate of 12.8%, entitled to Treaty benefits under the “Limitation on Benefits” provision contained in the Treaty who are U.S. residents, as defined pursuant to the provisions of the Treaty, will not be subject to this 25% or 75% withholding tax rate, but may be subject to the withholding tax at a reduced rate (as described below).

Under the Treaty, the rate of French withholding tax on dividends paid to an eligible U.S. holder who is a U.S. resident as defined pursuant to the provisions of the Treaty and the beneficial owner of these dividends and whose ownership of the ordinary shares or ADSs is not effectively connected with a permanent establishment or fixed base that such U.S. holder has in France, may be reduced to 15%, or to 5% if such U.S. holder is a corporation and owns directly or indirectly at least 10% of the share capital of the issuer; such U.S. holder may claim a refund from the French tax authorities of the amount withheld in excess of the Treaty rates of 15% or 5%, if any.

For U.S. holders that are not individuals but are U.S. residents, as defined pursuant to the provisions of the Treaty, the requirements for eligibility for Treaty benefits, including the reduced 5% or 15% withholding tax rates contained in the “Limitation on Benefits” provision of the Treaty, are complex, and certain technical changes were made to these requirements by the protocol of January 13, 2009. U.S. holders are advised to consult their own tax advisors regarding their eligibility for Treaty benefits in light of their own particular circumstances. Dividends paid to an eligible U.S. holder may immediately be subject to the reduced rates of 5% or 15% provided that:

Otherwise, dividends paid to a U.S. holder, other than individuals subject to the French withholding tax at a rate of 12.8%, will be subject to French withholding tax at the rate of 25%, or 75% if paid in a non-cooperative State or territory (as defined in Article 238-0 A of the FTC, other than those States or territories mentioned in 2° of 2 bis of the same Article 238-0 A), and then reduced at a later date to 5% or 15%, provided that such holder duly completes and provides the French tax authorities with the treaty forms Form 5000 and Form 5001 before December 31 of the calendar year following the year during which the dividend is paid (due to recent case law regarding the statute of limitation for filing a withholding tax claim; U.S. holders are advised to consult their own tax advisors in this respect).

Certain qualifying pension funds and certain other tax-exempt entities are subject to the same general filing requirements as other U.S. holders except that they may have to supply additional documentation evidencing their entitlement to these benefits.

Form 5000 and Form 5001, together with instructions, will be provided by the depositary to all U.S. holders registered with the depositary. The depositary will arrange for the filing with the French tax authorities of all such forms properly completed and executed by U.S. holders of ordinary shares or ADSs and returned to the depositary in sufficient time so that they may be filed with the French tax authorities before the distribution in order to immediately obtain a reduced withholding tax rate. Otherwise, the depositary must withhold tax at the full rate of 25% or 75% as applicable. In that case, the U.S. holders may claim a refund from the French tax authorities of the excess withholding tax.

Since the withholding tax rate applicable under French domestic law to U.S. holders who are individuals does not exceed the cap provided in the Treaty (i.e. 15%), the 12.8% rate shall apply, without any reduction provided under the Treaty.

Besides, please note that pursuant to Article 235 quater of the FTC and under certain conditions (in particular reporting obligations), a corporate U.S. holder which is in a tax loss position or which tax result is nil due to offset of tax losses (French Administrative Supreme Court, October 18, 2022, n°466329, Sté Brufinol) for the fiscal year during which the dividend is received may be entitled to a deferral regime, and obtain a withholding tax refund. The tax deferral ends in respect of the first financial year during which this U.S. holder is in a profit making position, as well as in the cases set out in Article 235 quater of the FTC. Finance Bill for 2022 (French Finance Bill n° 2021-1900) extended the deadline to claim the refund (December 31 of the second year following the year of payment instead of three months after the end of the fiscal year following the payment of the income) and clarify the order in which the deferred taxes become due (the forfeiture of the deferral applies in priority to the oldest withholding taxes).

Also, pursuant to Article 235 quinquies of the FTC and under certain conditions, a corporate U.S. Holder may be entitled to a refund of a fraction of the withholding tax, up to the difference between the withholding tax paid (on a gross basis) and the withholding tax based on the dividend net of the expenses incurred for the acquisition and conservation directly related to the income, provided (i) that these expenses would have been tax deductible had the U.S. Holder been established in France, and (ii) that the tax rules in the United States do not allow the U.S. Holder to offset the withholding tax.

Real Estate Wealth Tax

On January 1, 2018, the French wealth tax (“impôt de solidarité sur la fortune”) was replaced with a real estate wealth tax (“impôt sur la fortune immobilière”, or “IFI”). Individuals holding directly or indirectly through one or more legal entities real estate assets or rights with a value exceeding €1,300,000 may fall within the scope of the IFI. A general exclusion applies to real estate assets owned by companies carrying out a commercial or industrial activity when the taxpayer (together with the members of his/her household) holds directly or indirectly less than 10% of the share capital or voting rights of the company. Warrants, ordinary shares or ADSs owned by a U.S. holder should not fall within the scope of the IFI provided that such U.S. holder does not own (together with the members of his/her household) directly or indirectly a shareholding exceeding 10% of the financial rights and voting rights of our share capital. U.S. holders holding directly or indirectly a shareholding exceeding 10% of the financial rights and voting rights of our share capital should seek additional advice.

U.S. holders are advised to consult their own tax advisor regarding the specific tax consequences which may apply to their particular situation with respect to such French real estate wealth tax (impôt sur la fortune immobilière).

The discussion above is a summary of the material French tax consequences of an investment in ADRs and is based upon laws and relevant interpretations thereof in effect as of the date hereof, all of which are subject to change, possibly with retroactive effect. It does not cover all tax matters that may be of importance to a prospective investor. Each prospective investor is urged to consult its own tax advisor about the tax consequences to it of an investment in ADRs in light of the investor’s own circumstances.

Item 15. Indemnification of Directors and Officers
