Dealing with Internal Key Information and Guarding Inside Trading

In accordance with Article 8 of the “Regulations Governing Establishment of Internal Control Systems by Public Companies”, the Company settled “The management procedure of dealing with internal key information and guarding inside trading”, which prohibit insiders of the Company from trading securities using information not disclosed to the market. It is advisable that the rules include stock trading control measures from the date directors of the Company become aware of the contents of the company's financial reports or relevant results. Measures include, without limitation, those prohibiting a director from trading its shares during the closed period of 30 days prior to the publication of the annual financial reports and 15 days prior to the publication of the quarterly financial reports.

At least once a year, the Company handles the education and advocacy of "The management procedure of guarding inside trading" and "The management procedure of dealing with internal key information" and related laws and regulations for the current directors, managers and employees, and arranges the education advocacy for the new directors and managers after taking office. New employees are educated and promoted by personnel during pre-employment training.

In the quarterly email advocating the prohibition of insider trading, the company reminds insiders not to trade their shares during the closed period of 30 days prior to the publication of the annual financial reports and 15 days prior to the publication of the quarterly financial reports. The Company notified the insiders of the closure period prior to the publication of the quarterly financial reports to avoid misunderstanding of the Regulation on January 21, 2025, April 16, 2025, July 21, 2025, and October 22, 2025, respectively.
