Corporate Governance

Anti-Corruption Practices and Complaint Management

Management Approach

BDMS conducts its business in accordance with the principles of good corporate governance, emphasizing transparency, fairness, ethical conduct, and accountability. The Company maintains a zero-tolerance stance toward all forms of corruption, as stipulated in its Code of Conduct.

In 2025, the Company reviewed and updated its Fraud Prevention and Anti-corruption Policy to ensure alignment with applicable laws, regulations, and business-related requirements, as well as internationally recognized standards. The policy establishes reporting and complaint channels for violations of laws, unethical conduct, or activities that may constitute corruption.

The Company has implemented whistleblower protection measures and appropriate remediation mechanisms to mitigate potential adverse impacts. In parallel, various training programs and communication activities are conducted to enhance knowledge, understanding, and awareness among employees at all levels, as well as external stakeholders, regarding the Company’s anti-corruption policy. Clear whistleblower protection mechanisms have been established, together with strict disciplinary actions against individuals who engage in inappropriate behavior, intimidation, harassment, or discriminatory treatment toward whistleblowers.

The policy applies to the Board of Directors, executives, and employees at all levels and serves as a framework for preventing, mitigating, and addressing corruption risks within the organization. The Board of Directors actively promotes and communicates the policy to both internal and external stakeholders through appropriate communication channels.

Fraud Prevention and Anti-corruption Policy

BDMS places great importance on conducting business with transparency, fairness, ethics, and accountability, guided by the principles of Good Corporate Governance and responsibility toward all stakeholder groups. Accordingly, the Company has established an Anti-Corruption Policy as a framework for directors, executives, and employees across the Group. The policy adopts a strict zero-tolerance approach to all forms of corruption, whether direct or indirect.

The Company systematically manages corruption risks through risk assessments, risk prioritization, and regular internal audits to ensure compliance with applicable laws, regulations, and good corporate governance standards. Comprehensive internal control measures are implemented across key business processes, including procurement, contract management, disbursements, and financial recordkeeping. Clear approval authorities and supporting documentation requirements are established to enhance transparency and accountability.

In conducting business, the Company has established guidelines governing charitable donations, community contributions, business hospitality, and the giving or receiving of gifts. Such activities must be conducted appropriately and transparently and must not serve as a means of obtaining improper benefits or facilitating bribery. BDMS also maintains political neutrality and does not provide financial support or other benefits to political parties, politicians, or election candidates, thereby minimizing corruption and conflict-of-interest risks.

To foster a culture of integrity, the Company continuously communicates its anti-corruption policies and measures through training programs, meetings, intranet systems, and other internal communication channels. Training is also provided to enhance awareness and understanding among employees and relevant stakeholders regarding corruption risks, forms of misconduct, and preventive measures.

BDMS has established Whistleblowing Channels for reporting activities that may violate laws, ethical standards, or anti-corruption requirements. Reports can be submitted through multiple channels, and whistleblowers are protected under the Company’s Whistleblower Protection Policy, which includes confidentiality safeguards, anonymity protection, and protection against retaliation or harassment. All complaints are investigated fairly and transparently, and disciplinary actions are taken against offenders or individuals who retaliate against whistleblowers.

The Company accepts reports relating to the following matters:

• Violations of laws, fraud, Company regulations, or the Employee Code of Conduct
• Violations of the Board of Directors’ Code of Conduct
• Violations of medical ethics
• Irregularities in financial reporting
• Issues that may adversely affect the Company’s reputation and corporate image

Complaint /Notification Channels

The Audit Committee plays a key role in overseeing compliance with the policy, reviewing the adequacy of internal control systems, and reporting issues that may affect business transparency to the Board of Directors for timely corrective action. The Company regularly reviews and updates its anti-corruption policies and measures to ensure alignment with evolving laws, international standards, and sustainability-related best practices, thereby supporting transparent, responsible, and sustainable long-term growth.

In 2025, the Company recorded zero significant incidents of corruption or bribery. There were no legal cases, lawsuits, judgments, fines, or sanctions related to corruption or bribery imposed by regulatory authorities. This reflects the effectiveness of the Company’s governance framework, risk management processes, and anti-corruption measures.
