l Assessment
The company maintains a robust and comprehensive supply chain system, integrating and assisting suppliers in improving product quality and ensuring compliance with occupational health, safety, and environmental regulations to fulfill corporate social responsibility in safety and environmental protection.

• For contracted engineering suppliers, management is carried out in accordance with the "2-IS-2-K-001 Contractor Management Procedure." In addition to implementing autonomous safety and health management, providing education and training, organizing safety coordination meetings, and communicating workplace hazards before entry, strict requirements are also enforced for on-site environmental management.
• According to the "1-AD-2-B-001 Supplier Management Procedure," environmental management and social responsibility assessments are conducted for suppliers and new outsourced processing factories. The assessment items include:

a. Whether the supplier holds certifications such as ISO 14001 (Environmental Management System), ISO 45001 (Occupational Health and Safety Management System), and SA8000 (Social Accountability Certification).
b. Suppliers are evaluated using the "1-AD-4-B-006 Supplier Environmental Management Evaluation Form" and are required to submit supporting documentation, including fixed pollution source operation permits, wastewater discharge permits, toxic substance handling permits, waste disposal/treatment contracts, drinking water inspection reports, and fire safety inspection records, to demonstrate compliance with safety, health, and environmental requirements.
c. Suppliers are evaluated using the "1-AD-4-B-007 Social Responsibility Assessment Form," which includes contractual requirements for major suppliers and contractors to comply with labor laws and relevant human rights regulations. These include prohibitions on child labor and forced labor, ensuring health and safety, freedom of association and collective bargaining rights, and non-discrimination. If violations of corporate social responsibility policies are identified, particularly those with significant environmental or social impact, the company reserves the right to terminate or cancel the contract at any time.

The results of the responses were analyzed to identify the key ESG issues of concern to major suppliers, which will serve as the focus for promoting ESG initiatives in the coming years.
Moving forward, we will continue to expand the system's influence to include all suppliers, with the goal of establishing a comprehensive and responsible supply chain system.
