Item 3. Incorporation of Documents by Reference.

The following documents filed by the Registrant with the Commission are incorporated herein by reference:

(a)        the Registrant’s Annual Report on Form 20-F for the year ended December 31, 2025, filed with the Commission on March 26, 2026;

(b)       the Registrant’s Current Reports on Form 6-K furnished to the Commission on January 14, 2026, January 30, 2026 and March 19, 2026 (other than portions of the foregoing expressly excluded from incorporation by reference) (No. 001-40552); and

(c)        the description of the Registrant’s Ordinary Shares which is contained in the Registrant’s Registration Statement on Form 8-A (File No. 001-40552) filed with the Commission on June 28, 2021, including any amendment or report filed for the purpose of updating such description.

All reports and other documents filed by the Registrant after the date hereof pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), prior to the filing of a post-effective amendment which indicates that all securities offered hereby have been sold or which deregisters all securities then remaining unsold, shall be deemed to be incorporated by reference herein and to be part hereof from the date of filing of such reports and documents (the “Incorporated Documents”).

Any statement contained herein or in any Incorporated Document shall be deemed to be modified or superseded for the purposes of this Registration Statement to the extent that a statement contained in any subsequently filed Incorporated Document modifies or supersedes such statement. Any such statement so modified or superseded shall not be deemed, except as so modified or superseded, to constitute a part of this Registration Statement.

Item 4. Description of Securities.

Not applicable.

Item 5. Interests of Named Experts and Counsel.

Not applicable

Item 6. Indemnification of Directors and Officers.

Under Belgian law, the directors of a company may be liable for damages to the company in case of improper performance of their duties. The Registrant’s directors may be liable to the Registrant and to third parties for infringement of the Registrant’s articles of association or Belgian company law. Under certain circumstances, directors may be criminally liable.

The Registrant maintains liability insurance for the Registrant’s directors and officers, including insurance against liability under the Securities Act.

The New Belgian Companies Code that entered into force on January 1, 2020, includes a cap on liability for directors (including persons in charge of daily management) for any damages they cause due to mismanagement, including breaches of the articles of association and the New Belgian Companies Code. This liability cap applies towards the company and third parties. For the Registrant, the cap amounts to €12,000,000. The cap applies irrespective of the number of claimants or defendants for the same (set of) facts. However, the cap does not apply to repetitive minor misconduct, serious error or cases of fraud. Furthermore, the cap does not apply to directors’ liability under the special liability regimes relating to payment of withholding tax, VAT and social security contributions.

Certain of the Registrant’s non-executive directors may, through their relationships with their employers or partnerships, be insured and/or indemnified against certain liabilities in their capacity as members of the Registrant’s board of directors.

Item 7. Exemption from Registration Claimed.

Not applicable.

Item 9. Undertakings.

1. The undersigned Registrant hereby undertakes:

(a) 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.

(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)(i) and (a)(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.

(b) 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 herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) 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.

2. 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 herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

3. 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 Securities and Exchange 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.
