For the current term, three directors are due to retire from office by rotation, as follows: 1. Mr.Vanich Sirikarnjanasook (Position: Chief Executive Officer) (Term expired: April 2026) 2. Mr.Pruitipong Thaicham (Position: Director) (Term expired: April 2026) 3. Mr.Samart Masakee (Position: Director) In this regard, the Board of Directors' Meeting No. 10/2026 considered the qualifications, knowledge, capabilities, experience, and performance of the directors retiring by rotation and deemed it appropriate to propose to the Extraordinary General Meeting of Shareholders for consideration and approval the following appointments: 1. Re-election of Mr.Vanich Sirikarnchanasook, a director retiring by rotation, to serve as a director of the Company for another term; 2. Appointment of Dr.Thanasak Pornthapphasan as a new director of the Company, in replacement of Mr.Pruitipong Thaicham, who retires by rotation; and 3. Appointment of Mr.Paiboon Udomkarnkit as a new director of the Company, in replacement of Mr. Samart Masaki, who retires by rotation. Agenda Item : 2 Agenda Detail : To consider and approve the appointment of auditor and fix his/her remuneration for the year ended 31 December 2026 Type : To Consider and approve Agenda Item : 3 Agenda Detail : To consider and approve the appointment of the Company's auditor for the audit of the financial statements for the fiscal year ending December 31, 2028, to replace the resigned former auditor, and the determination of the audit fee Type : To Consider and approve Board's Resolution : Pursuant to Section 120 of the Public Limited Companies Act B.E. 2535 (1992), the power to appoint auditors and determine the audit fee belongs exclusively to the Shareholders' Meeting. Subsequent to the previous resolution of the Shareholders' Meeting appointing the Company's auditor for the fiscal year ending December 31, 2028, the appointed auditor tendered their resignation prior to the completion of the audit. This created a vacancy in the position of auditor and resulted in the Company's inability to prepare and submit its annual financial statements for the year 2028 within the statutory deadline. The nomination of auditors for the fiscal year 2028 at this time is legally grounded as an "appointment to fill a casual vacancy" so that the uncompleted financial statement audit may proceed to completion. This does not constitute a retroactive appointment in any respect; the nominated auditors will perform the full audit from the beginning in accordance with applicable auditing standards and legal requirements, without certifying or relying upon the work performed by the former auditor. Accordingly, pursuant to the resolution of the Board of Directors' Meeting No. 10/2026 (following the screening and selection by the Audit Committee), the Board considered the qualifications, independence, expertise, and operational readiness of the audit firm and deems it appropriate to propose that the Extraordinary General Meeting of Shareholders approve the appointment of auditors from D I A International Audit Co., Ltd. as the Company's auditors for the audit of the financial statements for the fiscal year ending December 31, 2028, replacing the resigned auditor, where any one of the following auditors shall be authorized to audit and express an opinion on the Company's financial statements: Mr. Nopparoek Pissanuwong, Certified Public Accountant (CPA) Registration No. 7764 Miss Raweewan Chuenchom, Certified Public Accountant (CPA) Registration No. 7487 Miss Somjintana Pholhirunrat, Certified Public Accountant (CPA) Registration No. 5599 Miss Suphaphorn Mangjit, Certified Public Accountant (CPA) Registration No. 8125. Furthermore, it is proposed to approve the audit fee for the financial statements of the fiscal year ending December 31, 2028, in the amount of THB 4,000,000 (Four Million Baht only), excluding out-of-pocket expenses actually incurred (such as travel expenses, documentation costs, and Value Added Tax (VAT)). ______________________________________________________________________ Change of director/Executive Expired by rotation Director Name : Mr. PRUITIPONG THAICHAM Position in company (1) : DIRECTOR Effective Date (1) : 26-Nov-2020 Expire Date (1) : 30-Apr-2026 Terminate Reason : Non-renewal of term (term expired) ______________________________________________________________________ Change of director/Executive Re-election Director Name : MR.
