1. Enterprise’s responsibility for internal control

In accordance with the provisions of the "Basic Standards for Enterprise Internal Control", "Guidelines for the Application of Enterprise Internal Control" and "Guidelines for the Evaluation of Enterprise Internal Control", it is the responsibility of the CSPC Innovation Board of Directors to establish, improve and effectively implement internal controls and evaluate their effectiveness.

2. Responsibilities of Certified Public Accountants

Our responsibility is to express an audit opinion on the effectiveness of internal control over financial reporting based on the implementation of the audit work, and to disclose the significant deficiencies in internal control over non-financial reporting that we have noticed.

3. Inherent limitations of internal control

Internal controls have inherent limitations and may fail to prevent and detect misstatements. In addition, since changes in circumstances may cause internal controls to become inappropriate, or the degree of compliance with control policies and procedures to be reduced, there is a certain risk in inferring the effectiveness of future internal controls based on the results of internal control audits.

4. Audit opinions on internal control over financial reporting

We believe that CSPC Pharmaceutical Innovation maintained effective internal control over financial reporting in all material aspects in accordance with the "Basic Standards for Corporate Internal Control" and relevant regulations on December 31, 2025.
