ISSUE OF SHARES PURSUANT TO EMPLOYEE SHARE INCENTIVE SCHEME

Reference is made to the announcements of ASMPT Limited (the "Company") dated 19 December 2024, 29 July 2025, 3 December 2025 and 5 May 2026 (collectively, the "Announcements") in relation to, amongst other things, the Award of Shares to Selected Employees under the Scheme. Unless otherwise defined herein, capitalised terms used in this announcement shall have the same meanings as those defined in the Announcements.

On 11 May 2026, pursuant to the authority conferred upon them under the Scheme and the authority given by the shareholders of the Company to the Board at the annual general meeting held on 7 May 2019, the Trustee has subscribed for new Shares in cash and the Company agreed to issue and to allot a total of 1,571,250 Awarded Shares to satisfy the Award of Shares referred to in the Announcements. Such Awarded Shares shall be allocated to each Selected Employee provided that the relevant Selected Employee has not ceased to be an employee and is not under notice to terminate his tenure of office and/or employment with the Group on the respective Vesting Date(s).

The 1,571,250 Awarded Shares in aggregate represent approximately $0.376\%$ of the existing issued share capital and approximately $0.375\%$ of the enlarged issued share capital of the Company after the allotment. When issued and fully paid, they rank pari passu amongst themselves and with the existing issued Shares, with the same rights as respects voting, dividends, transfer and all other rights, including those arising on liquidation, as all other issued Shares at the time of such allotment.

An application will be made by the Company to the Stock Exchange for the listing of, and permission to deal in, the 1,571,250 Awarded Shares which are to be issued and allotted under the Scheme.
