China BlueChemical Ltd. has issued a notice convening a Domestic Shareholders’ Class Meeting on 28 May 2026 in Haikou, immediately after the company’s H-shareholders’ meeting. The key agenda item is a special resolution to grant the Board a general mandate to repurchase up to 10% of the company’s issued overseas-listed foreign shares (H Shares), excluding any treasury shares, prevailing at the time the resolution is approved.

If passed, the mandate empowers the Board to determine detailed repurchase terms—including price, volume, timing and duration—open requisite overseas securities accounts, complete cross-border fund transfer and foreign-exchange formalities, cancel the repurchased shares, and amend the articles of association to reflect the reduced registered capital.

The “Relevant Period” for exercising the mandate is defined as the earliest of: 1) the conclusion of the 2026 annual general meeting; 2) 12 months from the date the resolution is passed at the 2025 annual general meeting and the corresponding class meetings; or 3) the date the authority is revoked or varied by shareholders via special resolution.

Share transfer registration for domestic shareholders will be suspended from 22 May 2026 to 28 May 2026, both dates inclusive. Domestic shareholders recorded on the register as of 28 May 2026 may attend and vote. Proxy appointments must be lodged at the company’s Beijing Secretary Office no later than 24 hours before the meeting.

The Board currently comprises eight directors: three executive directors (Hou Xiaofeng, Rao Shicai, He Qunhui), two non-executive directors (Shao Lihua, He Qizhong), and three independent non-executive directors (Lin Feng, Xie Dong, Yang Wanhong).
