Challenges and Opportunities

This approach helps minimize legal and financial risks, enhances stakeholder trust, attracts investment, and promotes long-term sustainable business practices. To ensure transparent governance and gain stakeholder confidence, GC is committed to responsible management, transparency, and strict compliance with applicable laws, regulations, and global standards. GC also promotes diversity within the Board of Directors to ensure a broad range of perspectives that reflect stakeholder needs and expectations. These commitments aim to enhance GC’s investment appeal and market value, while reducing exposure to legal and financial risks. Through building stakeholder confidence and fostering investor interest, GC continues to strengthen its position in the capital market.

Business Strategies

GC has appointed the Board of Directors and assigned their roles in corporate governance. The Company has also established the Corporate Compliance Policy and taken continuous actions to improve processes in compliance with international principles and standards. Meanwhile, GC fosters a corporate culture that adheres to ethics while encouraging executives and supervisors to act as a role model for employees at all levels. A system has also been put in place to track business operations and performance. Accordingly, any activities that are inconsistent with the principles of Corporate Governance and the Business Code of Conduct can be reported by stakeholders through GC’s whistleblowing channels for further appropriate actions.

Board Nomination and Board Diversity Policy

The Nomination and Remuneration Committee is charged with nominating and selecting qualified candidates for appointment as directors. List of the said candidates shall be indeed presented to Board of Directors’ and/or Shareholders’ Meetings for consideration and approval of director’s appointment. The process of nominating directors must be made in a systematic and transparent manner in accordance with the Company’s criteria for nomination and appointment of directors. In addition to considering laws and regulations of the Securities and Exchange Commission of Thailand (SEC) and the Stock Exchange of Thailand (SET), the nomination of directors shall take into account GC’s Articles of Association, the Corporate Governance and Business Code of Conduct Handbook, and Corporate Governance Code for listed companies 2017 (CG Code).

Moreover, GC also takes into account the Board Diversity Policy, which includes the ratio of independent directors and female directors (Gender diversity), the diversity of race or ethnicity and nationality as well as the diverse knowledge, skills, experience and specialization that correspond with the Company’s business industry (Materials Industry) according to GC Board Skills Matrix without any discrimination based on gender, ethnicity, nationality, color, race, or religion. GC also considers the directors’ pool of trusted organizations, namely the State Enterprise Policy Office (SEPO) and the Thai Institute of Directors Association (IOD) or the compilation of a list of candidates provided by the Nomination and Remuneration Committee. This would promote and achieve a diverse and suitable board composition, which enhances the Board of Directors’ performance consistent with the Company’s current and future business strategies and goals efficiently.

Details of Board Nomination and Board Diversity Policy can be found under Item (9) Nomination and appointment of Directors on page 17-18 in Corporate Governance and Business Code of Conduct Handbook as well as the Company’s criteria for nomination and appointment of directors.

Board Composition and Board Independence Statement

As of February 28th, 2025, GC’s board composition comprises 15 directors, fourteen of whom are non-executive directors and one executive director. In addition, GC clearly determines the board’s structure, composition, qualification as well as duty and responsibility to suit the size and nature of its business.

Additionally, GC mandates that more than half of the Board of Directors must be independent directors. This is to ensure that independent directors and entire board members can fulfill their roles and responsibilities efficiently and exercise independent judgment. The roles and responsibilities of the Chairman of the Board of Directors and the Chief Executive Officer are clearly separated. The two positions must not be held by the same person. In addition, GC establishes the definition of Independent Director Qualification which is different and more stringent than the Independent Director Qualification of Notification of Capital Market Supervisory Board Tor Jor. 39/2559, issued by the Securities and Exchange Commission of Thailand (SEC) and the Independent Director Criteria of S&P Global CSA.

In accordance with the Regulation on the Protection of Liabilities of Directors and Executives B.E. 2554 (2011), GC recognizes the importance of corporate management in today’s complex and highly competitive environment. Directors and executives are required to perform their duties in compliance with applicable laws, regulations, and resolutions, with honesty and integrity, and in the best interests of GC. However, even when such actions are taken within the appropriate legal framework and with the intent to benefit GC, they may still affect the interests of stakeholders and could result in directors or executives being personally sued. Therefore, GC stipulates that “there is no limitation to directors’ and executives’ liabilities” for any act or omission in the performance of their duties, or in connection with the performance of such duties, or in their capacity as directors or executives. Directors and executives are expected to perform their duties with due care, diligence, and accountability as individuals responsible for steering the direction of the organisation.

In addition, GC has established clear procedures and criteria for voting at shareholder meetings to promote transparency and safeguard shareholders' rights to participate in major decisions. This includes, but is not limited to, decisions on the sale or transfer of GC’s business, acquisition of other businesses, and amendments to GC’s Articles of Association, all of which require prior shareholder approval.

Details regarding shareholder meetings and voting rights can be found in the Company’s Articles of Association, which are publicly available on the corporate website.
