Shanghai-headquartered contract research organisation WuXi AppTec Co., Ltd. announced a marginal expansion of its Hong Kong-listed H-share capital after investors converted part of the company’s outstanding zero-coupon convertible bonds.

On 17 September 2026, holders of the company’s RMB 6.78 billion (USD-settled) zero-coupon convertible bonds due 2027 exercised conversion rights, resulting in the allotment of 1.94 million new H shares at HKD 153.00 each. The new shares represent approximately 0.36 % of WuXi AppTec’s issued H-share base immediately prior to the transaction.

Post-conversion, the number of issued H shares (excluding treasury shares) increased to 540.27 million from 538.33 million. Treasury shares were unchanged at 20.15 million. Consequently, the company’s total issued share capital (including treasury shares) rose to 560.42 million shares.

The board confirmed that the share issuance complied with all applicable listing rules and regulatory requirements, and that all proceeds due from the conversion have been received.
