On October 9th, WuXi AppTec (603259.SH) once again divested shares in its associate company WuXi XDC (2268.HK), completing a block trade valued at approximately HK$2.346 billion. This marks the company's fourth divestment of WuXi XDC shares, with cumulative investment gains from stock sales this year impacting net profit by RMB 4.351 billion.

According to the announcement, WuXi AppTec sold 30.3 million shares of WuXi XDC held by its indirect subsidiary through block trading on October 8th, representing approximately 2.47% of the latter's total share capital.

The net investment gain from this WuXi XDC stock sale is expected to contribute approximately RMB 1.679 billion to the company's 2025 after-tax net profit, accounting for more than 10% of the company's most recent audited net profit attributable to shareholders (for 2024).

This divestment action was already set in motion at the shareholders' meeting on September 23rd, when the company received authorization allowing its investment department to dispose of listed and tradable domestic and overseas stocks when market conditions are favorable, with a total ceiling of 15% of net assets attributable to shareholders. In other words, this reduction is part of a predetermined strategy and represents a continuation of the company's flexible asset structure adjustments within its authorized scope.

Looking back at WuXi AppTec's recent stock disposal operations, the company's monetization timing for WuXi XDC has been quite precise. Since this year, the company has conducted three previous sales on November 8, 2024, January 10, 2025, and April 1st, totaling 137 million WuXi XDC shares with cumulative transaction value of approximately HK$4.604 billion. Following this latest reduction, total proceeds have reached nearly HK$7 billion, with book gains significantly boosting the company's profit performance. WuXi AppTec's record-high net profit in the first half of 2025 was a direct result of these investment gains materializing.

Alongside capital operations, the company is also accelerating the reallocation of funds to its core business. WuXi AppTec indicated in its announcement that proceeds from this sale will be used for global capacity expansion and capability building, strengthening its integrated CRDMO business model, and continuing to attract and retain top scientific talent to support long-term growth of core businesses.

As of the close on October 10th, WuXi AppTec's stock price closed at RMB 104.72 per share, representing a year-to-date gain of 95.02%; WuXi XDC's stock price closed at RMB 71.85 per share, with a year-to-date increase of 134.42%.
