3SBio subsidiary Mandi Inc. grants shares under incentive plan

On October 20, 2025, Mandi Inc. resolved to issue 640 Mandi shares as awards to selected participants at a consideration of $1.0 per Mandi share. Of these, 290 Mandi shares will go to Mandi Group Limited, and 350 Mandi shares to Hero Grand. The total nominal value of these awards is $640.00.

Hero Grand is a connected person of 3SBio Inc. due to its ultimate beneficial ownership through a trust where Dr. LOU Jing, a director and substantial shareholder of 3SBio, is the settlor, protector, and a beneficiary. This grant constitutes a connected transaction, subject to reporting and announcement requirements but exempt from circular and independent shareholders’ approval.

The 640 awards represent approximately 6.84% of Mandi's issued share capital and 6.4% of its enlarged share capital post-issue. Following the awards, 3SBio's effective interest in Mandi will decrease from 100.0% to 93.6%, though Mandi will remain a subsidiary. This also constitutes a deemed disposal under Chapter 14 of the Listing Rules, with similar reporting exemptions.
