Guangdong Tianyu Semiconductor Co., Ltd. (Tianyu Semiconductor) has approved an on-market H-share repurchase plan designed to reacquire up to 5.90 million H shares, representing 10% of the company’s issued H-share capital (excluding any treasury shares) at the time the mandate was granted.

The programme will be executed under the general repurchase mandate approved at the 2025 annual general meeting on 19 May 2026 and will run from the board’s approval date—14 September 2026—until the mandate’s expiry, unless the limit is reached earlier or shareholders grant a new mandate.

Key parameters include: • Price cap: repurchases may not exceed 5% above the average closing price of the five preceding trading days on which Tianyu Semiconductor’s H shares are traded on the Hong Kong Stock Exchange. • Share treatment: all repurchased shares will be held as treasury stock for employee share ownership schemes, equity incentive plans or other permissible purposes. • Authorisation: the board has empowered the chairman (or a designated representative) to determine timing, volume and pricing, open necessary securities accounts and handle disclosures, subject to prevailing laws and listing rules.

The board stated that the repurchase plan reflects confidence in Tianyu Semiconductor’s development prospects and aims to safeguard corporate value while enhancing shareholder returns. The company will disclose progress in accordance with Hong Kong listing requirements, and notes that implementation could be adjusted or terminated in response to market or corporate conditions.

Investors are advised to exercise caution when dealing in Tianyu Semiconductor’s shares.
