SUPPLEMENTAL ANNOUNCEMENT IN RELATION TO TERMINATION OF ISSUE OF NEW H SHARES UNDER GENERAL MANDATE

Reference is made to the announcement of Voicecomm Technology Co., Ltd. (the “ Company ”) dated 10 April 2026 and 30 April 2026 (the “ Announcements* ”) in relation to the Subscription B. Unless the context requires otherwise, capitalised terms used in this announcement shall have the same meaning as defined in the Announcements.

The Board wishes to supplement the following information in relation to the Subscription B.

STATUS OF CONDITION PRECEDENT OF THE SUBSCRIPTION B

As disclosed in the Announcements, Completion B is conditional upon:

• (a) the Stock Exchange granting the listing of and permission to deal in the Subscription Shares B;

• (b) all necessary consents and approvals required to be obtained by the parties hereto in respect of the Subscription Agreement B and the transactions contemplated thereunder, including but not limited to the Subscription B, having been obtained;

– 1 –

• (c) the representations and warranties made by the Company under the Subscription Agreement B being true and accurate and not misleading as of the date of the Subscription Agreement B and the Completion Date B;

• (d) the representations and warranties made by the Subscriber B under the Subscription Agreement B being true and accurate and not misleading as of the date of the Subscription Agreement B and the Completion Date B; and

• (e) there has been no material adverse effect in, or effect on, the business, operations, assets, liabilities, financial condition or prospects of the Group, as of the date of the Subscription Agreement B and the Completion Date B.

As at the date of the Deed of Termination, (i) condition precedent (a) has not yet been fulfilled; and (ii) conditions precedent (c) and (e) were expected to be capable of being fulfilled.

Regarding condition precedent (b), shortly after the execution of the Subscription Agreement B on 10 April 2026, the Company’s PRC legal adviser highlighted that the Subscription B required careful assessment under the relevant PRC foreign exchange regulations administered by the State Administration of Foreign Exchange of the PRC. To ensure strict regulatory compliance, a comprehensive legal review was necessary to ascertain the precise registration or approval requirements applicable to the cross-border capital flow involved. As this compliance assessment process requires additional time to reach a definitive legal conclusion, the parties recognised that condition precedent (b) could not be satisfied within the practical timeframe leading up to the Long Stop Date B. In view of the regulatory timeline constraints and to provide certainty to both parties, the Company and the Subscriber B mutually agreed to terminate the Subscription Agreement B by way of the Deed of Termination.
