The Registration Statement relates to the registration of an aggregate of 17,727,200 class A ordinary shares of a par value of US$0.0001 each (the Shares) to be issued pursuant to the Company’s Share Incentive Plan 2025 adopted by the board of directors of the Company on 21 October 2025 (the Plan).

3 Opinions

On the basis of the examinations and assumptions referred to above and subject to the limitations and qualifications set forth in paragraph 4 below, we are of the opinion that:

Valid Issuance of Shares

(a) the Shares to be offered and issued by the Company pursuant to the provisions of the Plan, have been duly authorised, provided that to the extent any Awards granted under the Plan are Incentive Share Options, the Shares to be offered and issued by the Company pursuant to the provisions of the Plan will be duly authorised when the shareholders of the Company has approved the Plan in accordance with the provisions of the Plan and the Memorandum and Articles (such approval as the Shareholders' Approval), and, when issued and allotted by the Company in accordance with the provisions of the Plan, the Memorandum and Articles, the Board Resolutions, the Shareholders' Approval (if applicable) and once the Consideration fixed in accordance with the provisions of the Plan is fully paid for, will be validly issued, and (assuming that all of the Consideration is received by the Company) fully paid and non-assessable. Once the register of members of the Company has been updated to reflect the issuance, the shareholders recorded in the register of members will be deemed to have legal title to the Shares set against their respective names.

4 Limitations and qualifications

4.1 We offer no opinion:

(a) as to any laws other than the laws of the Cayman Islands, and we have not, for the purposes of this opinion, made any investigation of the laws of any other jurisdiction, and we express no opinion as to the meaning, validity, or effect of references in the Documents to statutes, rules, regulations, codes or judicial authority of any jurisdiction other than the Cayman Islands; or

Page 4 of 5

(b) except to the extent that this opinion expressly provides otherwise, as to the commercial terms of, or the validity, enforceability or effect of the Registration Statement, the accuracy of representations, the fulfilment of warranties or conditions, the occurrence of events of default or terminating events or the existence of any conflicts or inconsistencies among the Registration Statement and any other agreements into which the Company may have entered or any other documents.

4.2 Under the Companies Act (as revised) of the Cayman Islands (the Companies Act), the register of members of a Cayman Islands company is by statute regarded as prima facie evidence of any matters which the Companies Act directs or authorises to be inserted therein. A third party interest in the shares in question would not appear. An entry in the register of members may yield to a court order for rectification (for example, in the event of fraud or manifest error).

4.3 Our examination of the Register of Writs cannot conclusively reveal whether or not there is:

(a) any current or pending litigation in the Cayman Islands against the Company; or

(b) any application for the winding up or dissolution of the Company or the appointment of any liquidator, trustee in bankruptcy or restructuring officer in respect of the Company or any of its assets,

as notice of these matters might not be entered on the Register of Writs immediately or updated expeditiously or the court file associated with the matter or the matter itself may not be publicly available (for example, due to sealing orders having been made). Furthermore, we have not conducted a search of the summary court. Claims in the summary court are limited to a maximum of CI $20,000.

5 Governing law of this opinion

5.1 This opinion is:

(a) governed by, and shall be construed in accordance with, the laws of the Cayman Islands;

(b) limited to the matters expressly stated in it; and

(c) confined to, and given on the basis of, the laws and practice in the Cayman Islands at the date of this opinion.

5.2 Unless otherwise indicated, a reference to any specific Cayman Islands legislation is a reference to that legislation as amended to, and as in force at, the date of this opinion.
