Unless otherwise defined, capitalised terms used in this joint announcement shall have the same meanings as those defined in the Composite Document.

LEVEL OF ACCEPTANCE As at 4:30 p.m. on Wednesday, 5 August 2026, the Offeror has received valid acceptances in respect of a total of 530,964,256 Offer Shares (the “Acceptance Share(s)”) under the Share Offer, (representing approximately 51.74% of the total issued share capital of the Company as at the date of this joint announcement), which comprise acceptances in respect of (i) 320,546,403 Shares subject to the Irrevocable Undertaking executed by 5brothers; (ii) 168,888,700 Shares subject to the Irrevocable Undertaking executed by Leap Profit; (iii) 40,368,557 Shares subject to the Irrevocable Undertaking executed by Smart Canvas Investment Limited and (iv) 1,160,596 Shares subject to the Irrevocable Undertaking executed by Star Celestial Holdings Limited. THE SHARE OFFER HAS BECOME UNCONDITIONAL IN ALL RESPECTS

As set out in the Composite Document, the Share Offer is conditional upon, among others, the Offeror having received valid acceptances of the Share Offer (and, where permitted, such acceptances not having been withdrawn) by 4:00 p.m. on the Closing Date which will result in the Offeror and persons acting in concert with it holding more than 50% of the voting rights in the Company as at the Closing Date (the “Acceptance Condition”).

Taking into account the Acceptance Shares (subject to the completion of the transfer of these Acceptance Shares to the Offeror), the Offeror and persons acting in concert with it are interested in an aggregate of 530,964,256 Shares, representing approximately 51.74% of the total issued share capital of the Company as at the date of this joint announcement. Therefore, the Acceptance Condition has been satisfied as at the date of this joint announcement.

Accordingly, all Conditions set out in the section headed “CONDITIONS OF THE SHARE OFFER” in the “Letter from Nomura” in the Composite Document have been satisfied, and the Offeror announces that the Share Offer has become unconditional in all respects on 5 August 2026.

As disclosed in the Rule 3.5 Announcement, pursuant to the Irrevocable Undertakings, each of the Undertaking Shareholders has irrevocably undertaken to the Offeror to accept the Share Offer on or prior to the Closing Date in respect of all the Shares held by each of them, respectively, representing an aggregate of 551,148,534 Shares and approximately 53.70% of the issued share capital of the Company as at the date of this joint announcement.

Save for (i) the Acceptance Shares (which comprise acceptances in respect of 530,964,256 Shares subject to the Irrevocable Undertaking executed by 5brothers, Leap Profit, Smart Canvas Investment Limited and Star Celestial Holdings Limited) as disclosed above, and (ii) the remaining 20,184,278 Shares subject to the Irrevocable Undertaking executed by the remaining Undertaking Shareholder (i.e. NBNW Investment Limited), neither the Offeror nor parties acting in concert with it (i) held, controlled or directed any Shares and rights over Shares immediately before the commencement date of the Offer Period; (ii) has acquired or agreed to acquire any Shares or rights over Shares since the commencement of the Offer Period and up to the date of this joint announcement; or (iii) borrowed or lent any relevant securities (as defined in Note 4 to Rule 22 of the Takeovers Code) of the Company during the Offer Period.

## THE SHARE OFFER REMAINS OPEN FOR ACCEPTANCE

Accordingly, the Share Offer will remain open for acceptance until 4:00 p.m. on Friday, 21 August 2026 which will be the final Closing Date of the Share Offer.

Save as set out in this joint announcement, all other terms of the Share Offer as set out in the Composite Document and the Form of Acceptance remain unchanged. Further announcement on the results of the Share Offer will be made in accordance with Rule 19.1 of the Takeovers Code.
