Important Statement In accordance with the Enterprise Internal Control Norms System, the establishment, improvement, and effective implementation of internal controls, the evaluation of their effectiveness, and the truthful disclosure of the internal control evaluation report are the responsibilities of the company's Board of Directors. The Audit Committee supervises the Board of Directors in establishing and implementing internal controls. The management is responsible for organizing and leading the daily operations of the company's internal controls. The company's Board of Directors and its directors and senior management guarantee that the content of this report contains no false records, misleading statements, or significant omissions, and they shall bear individual and joint legal responsibility for the truthfulness, accuracy, and completeness of the report's content. The objective of the company's internal control is to reasonably ensure the legality and compliance of business operations, the safety of assets, and the truthfulness and completeness of financial reports and related information, thereby improving operational efficiency and effectiveness and promoting the achievement of development strategies. Due to the inherent limitations of internal control, it can only provide reasonable assurance for achieving these objectives. Furthermore, due to changes in circumstances that may render internal controls inappropriate, or a reduced degree of adherence to control policies and procedures, there is a certain risk in inferring the future effectiveness of internal controls based on the results of the internal control evaluation.

The Board of Directors believes that the company has maintained effective financial reporting internal controls in all material aspects in accordance with the requirements of the Enterprise Internal Control Norms System and relevant regulations. Based on the determination of material weaknesses in the company's non-financial reporting internal controls, as of the Internal Control Evaluation Report Base Date, the company has not found any material weaknesses in non-financial reporting internal controls. No factors have occurred between the date of this Internal Control Evaluation Report and the date of its issuance that affect the conclusion of the internal control effectiveness evaluation.
