Synertone Communication Corporation has issued a proxy form outlining arrangements for an extraordinary general meeting (EGM) to be held at 11:00 a.m. on 8 May 2026 at 5/F, United Centre, 95 Queensway, Admiralty, Hong Kong.

The sole agenda item is an ordinary resolution to approve the placement of new shares under a specific mandate, as detailed in the circular dated 14 April 2026.

Key timetable • Proxy deadline: 11:00 a.m. on 6 May 2026 (48 hours before the meeting). • Register of members closure: 5–8 May 2026, during which no share transfers will be processed. • Last day to lodge share transfers: 4:30 p.m. on 4 May 2026. • Record date for voting rights: 8 May 2026.

Shareholders who wish to attend and vote in person may still do so even if they have submitted a proxy, as completion and return of the proxy form will not preclude personal attendance.

Only one vote may be cast per share; in the case of joint holdings, the vote of the first-named holder on the register will prevail. All times refer to Hong Kong time.
