This includes information disclosed as required by law and event-driven information.

• Exercise cautious and prudent judgment when providing information. Do not disclose inside information, trade secrets, or information that could impact competitive business advantages to any individual or the public if the company has not yet reported such information to the Stock Exchange of Thailand.

• In the event that the company possesses other information that influences securities investment decisions, or any information that may impact the price or value of its securities, the company may disclose such additional information to the public beyond what is required by the Stock Exchange of Thailand. Such disclosure must be clear and contain sufficient detail for understanding, without misleading investors regarding investment in the company’s securities.

• In the event of rumors, information leaks, or misunderstandings among stakeholders, the company will promptly clarify the facts to the public in accordance with the regulations of the Stock Exchange of Thailand to establish a correct understanding, while clearly specifying other key conditions (if any).

• Establish information disclosure channels or data sources to ensure all users receive information on an equitable basis.

   2. Protection of Inside Information

• Do not use inside information for personal benefit or for the benefit of others, and do not disclose the company’s confidential information to third parties, or use one’s position or duties within the company to wrongfully seek benefits for oneself or others.

• Do not disclose inside information to any other person until such information has been publicly disclosed in accordance with the relevant criteria.

• Manage inside information and ensure its proper disclosure in accordance with relevant regulations prior to disclosing it to any specific group of investors.

• Refrain from trading the company’s securities during Blackout Periods in accordance with the Insider Trading Prevention Policy, which prohibits directors, senior executives, and employees who know or may possess inside information from buying, selling, or transferring the company’s shares for a period of one month prior to the release of financial statements.

3. Disclose information on an equitable and fair basis, ensuring that all relevant stakeholder groups have the opportunity to access and inquire about information.
