HUA HONG GRACE SEMICONDUCTOR LIMITED (HUA HONG SEMI) announced that the Shanghai Stock Exchange (SSE) has issued “SSE Review (Mergers, Acquisitions and Reorganisations) [2026] No. 26”, confirming preliminary acceptance of the company’s plan to acquire a target through a share issuance and to raise supporting funds.

The SSE’s feedback requires HUA HONG SEMI to submit a restructuring report (hearing version) before further review proceeds. Concurrently, the bourse tightened the lock-up arrangements for the consideration shares to be issued to three vendor funds:

• Shanghai IC Fund: 100 % of its consideration shares locked for 6 months from the date of issue.

• China IC Fund II: 10.16 million shares locked for 12 months and 9.89 million shares locked for 36 months.

• Guotou IC Fund: 100 % of its consideration shares locked for 36 months.

All other commercial terms of the proposed acquisition remain unchanged from those set out in the circular dated 22 January 2026.

Completion of the acquisition remains subject to approvals from relevant authorities. The subsequent non-public issuance of RMB shares will proceed only after the transaction closes. Investors are advised to exercise caution when dealing in HUA HONG SEMI securities.
