Reference is made to the prospectus (the “Prospectus”) of Graphex Group Limited (the “Company”) dated 8 April 2025 in relation to the Rights Issue on the basis of three (3) Rights Shares for every one (1) Consolidated Share held on the Record Date and the announcement of the Company dated 2 May 2025 in relation to the applications for the Rights Shares and number of Unsubscribed Rights Shares subject to the Compensatory Arrangements (the “Announcement”). Unless the context otherwise requires, capitalised terms used in this announcement shall have the same meanings as those defined in the Prospectus and Announcement.

RESULTS OF RIGHTS ISSUE

As disclosed in the Announcement, as at 4:00 p.m. on Thursday, 24 April 2025, being the Latest Time for Acceptance, a total of 11 valid applications had been received for a total of 64,826,370 Rights Shares, representing approximately 9.2% of the total number of Rights Shares offered under the Rights Issue. Accordingly, the remaining 639,457,686 Unsubscribed Rights Shares (each a “Placing Share”), representing approximately 90.8% of the total number of Rights Shares offered under the Rights Issue, were subject to the Compensatory Arrangements.

RESULTS OF THE COMPENSATORY ARRANGEMENTS

The Board is pleased to announce that as at 4:00 p.m. on Monday, 12 May 2025, being the latest time of Placing of the Placing Shares by the Placing Agent, 639,400,000 Placing Shares were successfully placed to twenty (20) independent placees at the Placing Price of HK$0.17 per Placing Share, which is equal to the Subscription Price, under the Placing. Therefore, there is no Net Gain available to be distributed to the No Action Shareholders under the Compensatory Arrangements.

Based on the acceptance results of the Rights Issue and the Placing results of the Compensatory Arrangements, the Rights Shares (including the Placing Shares) to be allotted and issued amounted to 704,226,370 Shares, representing 99.99% of the total number of Rights Shares offered for subscription under the Rights Issue.

To the best of the Directors’ knowledge, information and belief after having made all reasonable enquiries, each of the placees under the Placing and where appropriate, their respective ultimate beneficial owner(s), is independent of and not connected with the Company and its connected persons and not a connected person of the Company. As all the conditions with respect to the Rights Issue as set out in the Prospectus have been fulfilled, the Rights Issue became unconditional at 4:00 p.m. on Tuesday, 13 May 2025.

The gross proceeds raised from the Rights Issue (including the Placing) before expenses were approximately HK$119.7 million and the net proceeds from the Rights Issue after deducting the expenses and after expenses were approximately HK$115.7 million.

As disclosed in the Prospectus, the Company intends to apply the net proceeds from the Rights Issue of approximately HK$115.7 million as follows: as to (i) approximately HK$57.9 million or 50.0% of the maximum net proceeds for the implementation of the Phase 2 Project in Laixi City, the PRC; (ii) approximately HK$34.7 million or 30.0% of the maximum net proceeds for repayment of loans and interests of the Group; and (iii) approximately HK$23.1 million or 20.0% of the maximum net proceeds as general working capital of the Group including salary and rental payments for the coming nine to twelve months.

Notes:

DESPATCH OF SHARE CERTIFICATES

The share certificates for all fully-paid Rights Shares are expected to be posted on Thursday, 22 May 2025 to those entitled thereto at their registered addresses by ordinary post at their own risks. Given the Rights Issue has become unconditional, no monies received in respect of the relevant PALs will be refunded, and no refund cheque will be posted, to any accepting or applying shareholders.

COMMENCEMENT OF DEALINGS IN THE RIGHTS SHARES

Dealings in the fully-paid Rights Shares on the Stock Exchange are expected to commence at 9:00 a.m. on Friday, 23 May 2025.

Immediately upon the completion of the Rights Issue, the adjusted number of Shares issuable on the exercise in full of the Outstanding Share Options will become 3,450,306 at an adjusted exercise price of HK$1.82 per Share.
