Investor Relations Code of Ethics

The company places great emphasis on the accurate and equitable disclosure of information, including performance reports and general updates. To facilitate effective communication between shareholders, investors, and the company, an Investor Relations Department has been established. For inquiries, stakeholders can contact the department via phone at 065-992-2388 or email at investor@nerubber.com.

To ensure that investor relations activities are conducted correctly, thoroughly, transparently, and fairly, the company has adopted an Investor Relations Code of Ethics to guide its operations. The key principles are as follows:

• Accurate and Timely Disclosure
  The company commits to disclosing essential and necessary information accurately, comprehensively, and promptly, in compliance with the requirements of regulatory bodies, such as the Securities and Exchange Commission (SEC) and the Stock Exchange of Thailand.
• Equitable Information Disclosure
  The company ensures that all stakeholders have equal access to information, thereby preventing any party from gaining an unfair advantage or investment opportunity.
• Equal Treatment of Investors
  All investors, regardless of their status as major or minor shareholders, are treated equitably.
• Analyst Meetings
  Analyst meetings are organized with invitations extended equally to analysts from all securities companies.
• Media Communication
  The company provides appropriate information to the media and ensures that they have equal access to necessary updates.
• Collaboration with Authorities
  The company cooperates fully with regulatory authorities by providing information as requested.
• Equal Information Access for Stakeholders
  Information is provided to stakeholders on an equitable basis. In exceptional cases where business operations require selective disclosure (e.g., to financial institutions, credit rating agencies, or consultants), appropriate precautions are taken, such as requiring recipients to sign confidentiality agreements.
• Integrity and Non-Exploitation
  The company conducts investor relations activities with honesty and integrity, avoiding any personal gain derived from relationships or information obtained in the course of these activities.
• Quiet Period
  A quiet period of 14 days prior to the financial statement release is enforced, during which no meetings or information-sharing sessions with analysts or investors are permitted.
• Blackout Period
  A blackout period is established, prohibiting individuals in possession of inside information, including the investor relations team, from trading company shares. This period begins one month prior to the financial statement release date and ends one day after the release.

This Code of Ethics serves as a framework to ensure that the company’s investor relations practices are conducted in a manner that fosters trust, fairness, and transparency, thereby upholding the interests of all stakeholders.
