Our Board of Directors recognizes the importance of good corporate governance in the Company’s sustainable growth path, creating shareholder values, and securing trust from all stakeholders. Therefore, we have been emphasizing good corporate governance practices within the Company, our subsidiaries, and affiliates.

We are pleased to inform you that through our efforts, The Thai Institute of Directors Association (IOD) for Corporate Governance Report of Thai Listed Companies 2021 has assessed and rated our Company as “Excellent” or “5 Stars”, the highest rating possible. Another noteworthy rating is the Annual General Meeting Checklist from the Thai Investors Association in which we received 98 points (out of 100). For our continued work on sustainable development initiatives, we have also been included in the Thailand Sustainability Investment list for 4 consecutive years.

To further improve our Corporate Governance standards, we have joined the “Thailand’s Private Sector Collective Action Coalition Against Corruption” (CAC) and certified on 10 November 2017. We have also adopted the Corporate Governance Code for listed companies in 2017 from the Securities and Exchange Commission.
