WuXi XDC Cayman Inc. (the “Company”) released a supplemental announcement regarding its continuing connected transactions. The document provides further information on the pricing policies related to the Conjugation Discovery Services Agreement, which was previously announced on September 22, 2025.

The Company clarifies that the service fees will be determined using a standard pricing schedule, ensuring that the rates for connected parties are no more favorable than those offered to independent third-party customers. Factors considered in formulating the standard pricing schedule include the nature, scale, and complexity of the services, as well as the resources required and historical fees for comparable transactions. For each conjugation discovery project, individual purchase orders or agreements will specify the exact service scope and fees, which will be counter-checked and approved with reference to at least two comparable quotations, if available.

According to the announcement, the management and relevant personnel oversee and monitor the pricing policy to ensure transactions are conducted on normal commercial terms. Apart from this supplemental information, the Company states that all other details in its earlier announcement remain unchanged.
