Block Admission Application

Hong Kong, Shanghai & Florham Park, NJ - Friday, June 5, 2026: HUTCHMED (China) Limited ("HUTCHMED" or the "Company") (Nasdaq/AIM: HCM; SEHK:13) today announces an application has been made to the London Stock Exchange plc for a block admission of 43,616,756 ordinary shares, par value of US$0.10 each ("Ordinary Shares") to be admitted to trading on AIM.  It is expected that such admission will become effective on June 11, 2026.

These Ordinary Shares will be issued from time to time pursuant to the exercise of share options under the Share Option Scheme adopted by the Company in 2026 ("2026 Share Option Scheme").  When issued, these Ordinary Shares will be credited as fully paid and will rank pari passu with the existing Ordinary Shares in issue. The Company is seeking this block admission due to the adoption of the 2026 Share Option Scheme, as approved at its annual general meeting held on May 12, 2026 ("AGM"), whereby the Company was empowered to grant options under that scheme in respect of a maximum of 43,616,756 Ordinary Shares. Following admission, the total issued share capital of the Company remains unchanged at 872,335,120 Ordinary Shares, with each share carrying one right to vote and with no shares held in treasury.  The Company will make six-monthly announcements of the utilisation of the block admission, in line with its obligations under AIM Rule 29 and monthly announcements as to any changes to its total voting rights.

The balance of the existing block admission in respect of the Company's previous share option scheme adopted in 2015 of 45,768,368 Ordinary Shares (the "Existing Block Admission") remains in effect.
