Prevent insider trading

Specific implementation of "Preventing Insider Trading"

The Company provides education and promotion of the "Regulations on Prevention of Insider Trading" and related laws to current directors, independent directors, managers and employees at least once a year, and to new directors, independent directors and managers within 2 months after taking office. Education and promotion are arranged within the company, and for new employees, education and promotion are provided by the human resources department during pre-job training. On December 12, 2025, a total of 22 persons, including current directors, independent directors, managers and employees, received relevant education and promotion. The course lasted for 0.5 hour and included Article 10 of the Code of Practice on Corporate Governance for Listed Companies. Article 11 of the course prohibits company insiders from using undisclosed market information to buy or sell securities during a specific period, and places course briefing files in the internal employee system for reference by those who did not attend that day. The Company stipulates in its “Procedures for Handling Material Inside Information and Preventing Insider Trading” that directors are prohibited from trading the Company’s shares during the closed period of thirty days prior to the announcement of the annual financial report and fifteen days prior to the announcement of each quarterly financial report. In addition, the Company reminds directors of this prohibition in its annual courses on the prevention of insider trading, so as to prevent directors from inadvertently violating the relevant regulations.
