Commitment to Signing the Codes of Conduct

To ensure that business ethics and the principles of integrity in business operations are fully implemented throughout the organization and value chain, the Company requires 100% of Board members and all employees to sign commitments to the relevant codes of conduct, thereby strengthening professional ethics and accountability. Board members are required to receive orientation on the relevant codes of conduct and complete the signing of declarations before assuming office. For new employees, the codes of conduct are incorporated into employment contracts and must be read and signed upon onboarding. Incumbent employees are also required to sign relevant commitment documents where necessary, depending on the nature of their duties or project requirements.

In terms of business partner management, the Company requires suppliers to comprehensively sign relevant commitment documents, including the Supplier Due Diligence Questionnaire, Statement of Social Responsibility Policy and Commitment, Conflict Minerals Declaration, Integrity Commitment Letter, and Quality Commitment Letter. Where special procurement or cooperation needs arise, a Non-Disclosure Agreement (NDA) must also be signed as appropriate. Through the above institutionalized management mechanisms, the Company ensures that the principles of integrity and responsible business conduct are embedded across all levels and throughout the supply chain as an important foundation for sustainable operations.
