Honesty and Integrity
Policies and Regulations for Ethical Operations
OSE has always upheld the core values of Integrity, Innovation, Proactiveness, and Empathy. We believe that corporate integrity and business ethics form the foundation of sustainable governance, and all business activities are conducted with fairness and transparency. To this end, we have established regulations such as the Code of Business Ethics, OSE Supplier Code of Conduct, and Employee Code of Conduct and Ethics, which strictly prohibit any involvement in unethical business practices.
To ensure effective implementation, the Board of Directors and management commit to leading by example in practicing integrity. A robust internal control and audit mechanism is established, with the audit unit regularly supervising and reviewing the execution of integrity policies across all units. Additionally, all significant company information is disclosed in accordance with applicable laws and regulations. Directors are required by law to abstain from voting on proposals in which they have personal interests, safeguarding shareholder rights and promoting fairness in corporate governance.
To provide stakeholders—including employees, suppliers, and contractors—a clear channel for complaints and reporting of misconduct, OSE has established Complaint and Report Handling Procedures, featuring both internal and external hotlines and email addresses. These are publicly available on the company website to ensure unobstructed reporting channels and protection of whistleblower identity and rights.
To deepen the culture of integrity, OSE incorporates integrity clauses into contracts with agents, suppliers, customers, and other partners, and requires the signing of a Declaration of Integrity in supplier management. This encourages business partners to jointly uphold integrity management and amplifies its impact externally.
In 2024, OSE continued to review the completeness and effectiveness of its systems based on the Corporate Governance Best Practice Principles for TWSE/TPEx Listed Companies and corporate governance evaluation indicators, striving to build a fair, transparent, and accountable governance system. During the year, the company proactively disclosed significant information related to an administrative omission incident, implemented corrective measures, and optimized internal processes, demonstrating its commitment to transparency and honest disclosure. For more details, please refer to [2.4.3 Legal Compliance] in this report.

For external partners, OSE clearly defines the principle of integrity prior to any transaction and requires them to sign a Declaration of Integrity or include integrity clauses in contracts, jointly fostering a fair and transparent business environment. For suppliers and contractors, OSE conducts relevant awareness campaigns and training covering the Supplier Code of Business Ethics, labor and human rights policies, business ethics, occupational safety and health standards, and more, to strengthen integrity and responsibility throughout the supply chain.
In 2024, a total of 45 new suppliers signed integrity commitments. For detailed disclosures, please refer to the ESG Report [Chapter 4: Supply Chain and Product Management].
OSE will continue to promote institutional awareness and education of the integrity code, embedding the principle of integrity deeply into corporate culture and extending it throughout the entire value chain, thereby building a foundation for long-term and sustainable governance.

Reporting and Complaint Channels and Mechanisms
OSE established a “Reports/Complaints Handling SOP” to ensure the implementation of ethical business practices and provide a proper framework for employees, suppliers, and contractors to report and address instances of unfair treatment or misconduct. We’ve also set up internal and external hotlines and mailboxes. The reporting system and channels are also disclosed on the company’s website to encourage employees and external stakeholders to report any dishonest or inappropriate behavior at OSE.


In 2024, OSE had no confirmed cases of corruption and did not receive any penalties from regulatory authorities due to corruption-related violations. Additionally, there were no allegations of illegal, unethical, or dishonest business practices lodged against the company.
OSE values the practice of sustainable development and aims to continuously strengthen the management of various issues through pragmatic response measures, a spirit of continuous improvement, and transparent and effective communication.
