   and Risk Management Committee, Executive President of Petchem, and Chairman of ESG Council;

2. Mr. Dilip Kumar Agarwal Non-Executive Director;

3. Mr. Rathian Srimongkol Lead Independent Director, Vice Chairman of the

   Board, Chairman of the Audit Committee, and Member of the Sustainability and Risk Management Committee; and

4. Mrs. Kaisri Nuengsigkapian Independent Director, Member of the Audit

Committee, and Member of the Nomination, Compensation and Corporate Governance Committee

The Company had given the opportunity to shareholders to propose any candidate for directorship through the Company's website from 5 September 2025 to 31 December

2025 and also informed through the Stock Exchange of Thailand. There was no proposal received from any shareholder.

The directors retiring by rotation, namely, Mr. Yashovardhan Lohia, Mr. Dilip Kumar Agarwal, Mr. Rathian Srimongkol, and Mrs. Kaisri Nuengsigkapian, have given their consent for reappointment to the Nomination, Compensation and Corporate Governance Committee (the "NCCG Committee").

In addition, among the four directors who have given their consent for reappointment, Mr. Rathian Srimongkol and Mrs. Kaisri Nuengsigkapian are independent directors whose qualifications conform to the Company's Qualifications of Independent Directors and who have the ability to express independent judgment in respect of the Company's business operations and in compliance with the relevant regulations and laws. For the re-election of Mr. Rathian Srimongkol, if re-elected this year, his directorship as an independent director would continue for more than 9 years. However, he satisfies the Company's nomination and other relevant criteria for continuing as an independent director and as the Chairman of the Audit Committee. During his term of directorship, he has performed his duties well, and he has brought his expertise and knowledge to make recommendations which were highly beneficial to the Company in directing its strategy and policies. The NCCG Committee, after considering the experience of both Mr. Rathian Srimongkol and Mrs. Kaisri Nuengsigkapian and their contribution to the Company during their past tenure, deemed it appropriate to reappoint them for another term and thus recommended their reappointment to the Board.

The profiles of the retiring directors proposed for re-election and Qualification of Independent Director are provided in Annex 3.

the Company's Articles of Association, the appointment of the Company's auditor and audit fee are required to be approved by shareholders at the Annual General Meeting of Shareholders for each year.

No. 6105, or any other Certified Public Accountant nominated by KPMG Phoomchai Audit Limited as the Company's auditors for the year 2026.

The Board reviewed and recommended to the shareholders the remuneration of the Independent and Non-Executive Directors for the year 2026 and the annual bonus for all IVL Directors payable for the year 2025 performance as recommended by the Nomination, Compensation and Corporate Governance Committee ("NCCG Committee").

The Policy followed by the NCCG Committee to recommend to the Board and the shareholders the compensation and benefits of Independent and Non-Executive Directors are as follows:

• Compensation should fairly pay directors for work required in a company commensurate with the size and scope of the work;

• Compensation should, if possible, align directors' interests with the long-term interests of shareholders;

• Structure of the compensation should be simple, transparent and easy for Shareholders to understand;

• Compensation for Non-executive Directors and Independent Directors is inclusive of monthly retainer fee and annual bonus based on the previous year's Company performance; and

• Additional compensation will be paid to directors serving on various sub committees.

To implement the policy, the NCCG Committee has designed an appropriate compensation package based on comparable listed Companies with the following criteria:

There have been no changes made to the current retainer fee for the Independent and Non-Executive Directors for the year 2026.

No retainer fee to be paid to the Executive Directors on the Board.

The remuneration of the Chairman of the Board and Chairmen of the sub committees who are either independent or Non-Executive Directors is calculated at approx. 1.25 times of the other members.

In determining the bonus payable to all Directors, the NCCG Committee assesses the performance of directors based on their contribution, responsibilities, expertise and attendance.

The bonus amount is determined taking into consideration the profit and the dividend payment of the financial year and uses a point system to allocate bonuses amongst the directors as approved by the Board.

The Board of Directors' Meeting No. 2/2026 dated 27 February 2026 has considered the remuneration of Directors for the year 2026 as recommended by the NCCG Committee as not exceeding Baht 21,500,000.
