Zhong Ji LS (Stock Code: 00767) has executed a second supplemental agreement to refine its previously announced plan to acquire 25% of Asian Integrated Cell Laboratory Limited. The revisions center on two areas—profit guarantees and convertible note terms—following structural changes in the target group.

Key Updates 1. Profit Guarantee Scope Expanded • The vendor and guarantor continue to warrant that the Target Company will deliver audited pre-tax profits of no less than HK$50.00 million for each of the 12-month periods ending 31 December 2025 and 31 December 2026. • As of 3 March 2026 and 9 April 2026, the HK Company and the PRC Company became wholly owned subsidiaries of the Target Company. Accordingly, the guarantee now covers the entire “Target Group,” not just the original Target Company.

2. Convertible Note Flexibility Introduced • If converting the issued convertible notes would either (i) trigger a mandatory general offer under the Takeovers Code or (ii) cause public float to dip below 25%, the notes’ maturity will automatically extend. • The maturity extension applies until the first date on which conversion complies with both takeover and public-float regulations, or until a later date mutually agreed by the Company and noteholders.

Background and Timeline • Original Sale and Purchase Agreement announced on 1 December 2025. • First supplemental agreement disclosed on 2 April 2026. • Second supplemental agreement signed on 21 August 2026 to incorporate the above amendments.

Board Composition (as at 21 August 2026) Executive Directors: Yan Li (Chairman), Li Xiaoshuang Non-Executive Directors: He Yiwu, Lyu Changsheng Independent Non-Executive Directors: Huang Jiang, Huang Cibo, Wang Huijuan, Tam Mei Chu
