China Unicom (Hong Kong) Limited has issued a circular outlining key matters to be voted on at the Annual General Meeting (AGM) scheduled for 10:00 a.m. on 26 May 2026. The meeting will be held concurrently at Level 5, Island Shangri-La Hotel, Hong Kong, and at China Unicom Building, Beijing, with electronic participation enabled.

AGM PROPOSALS 1. Share buy-back authority • The Board seeks renewal of a general mandate to repurchase up to 10% of issued shares, excluding any treasury shares. • Based on 30.60 billion shares outstanding as of 20 April 2026, the mandate would allow the company to repurchase up to 3.06 billion shares. • Repurchases may be financed from available cash or working-capital facilities and carried out on the Hong Kong Stock Exchange or other recognised venues.

2. General mandate to issue shares • Directors propose a mandate to issue new shares not exceeding 20% of current issued share capital. • The aggregate issuance limit can be increased by the number of shares actually bought back under the above mandate, capped at an additional 10%.

3. Director re-elections • Four directors are nominated for re-election: – Executive Directors: Dong Xin (Chairman & CEO) and Tang Yongbo. – Independent Non-Executive Directors: Cheung Wing Lam Linus and Fan Chun Wah Andrew. • Biographical details and independence confirmations have been provided; both independent directors meet Listing Rule 3.13 independence requirements.

4. Final dividend • A final dividend of RMB0.1329 per share for FY 2025 is proposed, subject to shareholder approval. • Expected payment date: on or about 24 June 2026 in Hong Kong dollars. • Dividend record date: 5 June 2026; share transfer registration closes the same day.

KEY DATES • Last day to lodge share transfers for AGM attendance: 15 May 2026 (4:30 p.m.). • Register closure for AGM: 18-26 May 2026. • Proxy form deadline: 24 May 2026 (48 hours before AGM). • Register closure for dividend entitlement: 5 June 2026.

OTHER INFORMATION • No shareholder is required to abstain from voting; all resolutions will be decided by poll. • The company held no treasury shares as of the latest practicable date and conducted no share repurchases in the six months preceding 20 April 2026. • Immediate controlling shareholders Unicom BVI and Unicom Group BVI together hold 79.93% of issued shares; a full 10% buy-back would raise their aggregate holding to 88.82%, staying above the 50% threshold that triggers a mandatory offer under the Takeovers Code.
