CLARIFICATION ANNOUNCEMENT IN RELATION TO PROXY FORM

Reference is made to the proxy form (the "Proxy Form") of Silkwave Inc (the "Company"), which accompanied the circular of the Company dated 29 April 2025 (the "Circular"), for use at the annual general meeting of the Company to be held on Friday, 27 June 2025 (the "AGM") (and at any adjournment thereof). Unless otherwise defined, capitalized terms used in this announcement shall have the same meanings as defined in the AGM notice, the Circular and the Proxy Form.

Due to an inadvertent clerical error in the English version of the Proxy Form, the Company would like to inform the shareholders of the Company that the meeting place of the AGM should be 12/F, Guangdong Finance Building, 88 Connaught Road West, Hong Kong instead of the AGM to be held virtually.

Except as disclosed above, all the other information contained in the English version of the Proxy Form remain unchanged. This clarification announcement is supplemental to and should be read in conjunction with the Circular and the Proxy Form. The error does not affect the validity of the proxy form, and all submitted proxy forms will remain effective. Shareholders are not required to take any action as a result of this correction.
