Integrity in business operations is the cornerstone of Dyaco. In 2012, Dyaco implemented the "Sustainable Development Practice Guidelines,” “Integrity Operation Guidelines," and "Code of Ethics" as the highest guiding principles to comply with the company act, securities and Exchange Act, Commercial Accounting Act, etc., and other relevant laws and regulations governing business practices. We also follow the "Integrity Operation Guidelines" and "Procedures for Ethical Management and Guidelines for Conduct" as our guide, which outlines management procedures for conducting business with integrity, protecting whistleblowers, and avoiding inappropriate gains. Dyaco's management department is responsible for planning and implementing relevant measures. It requires all employees and business partners to follow the norms and regulations to ensure compliance with ethical policies and professional standards. In 2024, there were no incidents of unethical business practices such as anti-competitive behavior, antitrust and monopoly behavior, or market manipulation.
