EXPLANATORY NOTE

This Post-Effective Amendment (this “Post-Effective Amendment” or this “Amendment”) to the below listed Registration Statements (as defined below) is being filed pursuant to Rule 414 under the Securities Act of 1933, as amended (the “Securities Act”), by Criteo S.A., a Luxembourg public limited liability company (“Lux Criteo”), as the successor issuer to Criteo S.A., a French public limited liability company (“French Criteo” or the “Predecessor Registrant”). On July 29, 2026 (the “Effective Time”), pursuant to a corporate redomiciliation from France to Luxembourg via a cross-border conversion (the “Conversion”), French Criteo was converted, without being dissolved, wound up or placed into liquidation, into Lux Criteo, thereby transferring its registered office and central administration to the Grand Duchy of Luxembourg, while retaining its legal personality and continuing the terms of office of its directors as of the Effective Time. This Post-Effective Amendment relates to the following Registration Statements on Form S-8 (collectively, the “Registration Statements”), filed by the Predecessor Registrant with the Securities and Exchange Commission (the “Commission”):

•Registration No. 333-192024 originally covering up to 14,501,226 ordinary shares (“French Criteo Ordinary Shares”), €0.025 nominal value per share, of French Criteo under French Criteo’s 2009 Stock Option Plan FR/US, 2010 Stock Option Plan, 2011 Stock Option Plan, 2012 Stock Option Plan, 2013 Stock Option Plan, BSA Subscription Plan, BSPCE Subscription Plan and 2013 Free Share Plan.

•Registration No. 333-207658 originally covering up to 2,834,786 French Criteo Ordinary Shares under French Criteo’s 2015 Performance-Based Free Share Plan and 2015 Time-Based Free Share Plan.

•Registration No. 333-266367 originally covering up to 9,000,000 French Criteo Ordinary Shares under French Criteo’s Amended 2016 Stock Option Plan, Amended and Restated 2015 Performance-Based Restricted Stock Units Plan, and Amended and Restated 2015 Time-Based Restricted Stock Units Plan.

As a result of the Conversion, at the Effective Time, each French Criteo Ordinary Share was converted into one share of Lux Criteo (“Lux Criteo Ordinary Shares” or “shares”), each time-based restricted stock unit and performance-based restricted stock unit of French Criteo continued as a time-based restricted stock unit and performance-based restricted stock unit, respectively, of Lux Criteo and each option or warrant to obtain French Criteo Ordinary Shares continued as an option or warrant to obtain an equal number of Lux Criteo Ordinary Shares, respectively.

In addition, the offerings under each of the 2009 Stock Option Plan FR/US, 2010 Stock Option Plan, 2011 Stock Option Plan, 2012 Stock Option Plan, 2013 Stock Option Plan, 2013 Free Share Plan, 2014 Stock Option Plan, 2014 Free Share Plan and BSPCE Subscription Plan (collectively, the “Prior Plans”) have terminated, no further awards will be made under the Prior Plans and no awards previously granted under the Prior Plans remain outstanding. In accordance with the undertakings made by the Registrant in the following Registration Statements – Registration No. 333-192024 and Registration No. 333-197373 – this Post-Effective Amendment is being filed to remove from registration all of the shares previously registered for offering and sale by the Registrant pursuant to the Prior Plans that remain unsold and unissued as of the date hereof, and such Registration Statements are hereby amended, as appropriate, to reflect the deregistration of such shares. No other securities registered for offering and/or sale pursuant to the Registration Statements are being deregistered hereby, and this Post-Effective Amendment shall not affect any awards granted or to be granted under the Amended 2016 Stock Option Plan, Amended and Restated 2015 Performance-Based Restricted Stock Units Plan, Amended and Restated 2015 Time-Based Restricted Stock Units Plan and BSA Subscription Plan.

Unless the context otherwise requires or otherwise expressly stated, all references herein to the “Registrant” (i) for periods until the Effective Time, refer to French Criteo and its consolidated subsidiaries and (ii) for periods after the Effective Time, refer to Lux Criteo and its consolidated subsidiaries.

Item 9. Undertakings.

(a) The undersigned Registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act.

(ii) To reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective Registration Statement.

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement;

provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the Registration Statement.

(2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(b) The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
