The Chairman introduced the three Independent Directors attending the Meeting who were also appointed as proxy holders by minority shareholders, namely Mr. Krishna Boonyachai, Assoc. Prof. Dr. Narongdech Srukhosit, and Miss Choosri Kietkajornkul.

The Chairman introduced a representative from EY Office Limited as the appointed company's auditors, namely Mr. Kittiphun Kiatsomphob and also introduced the legal advisor from TTT & Partners Company Limited, namely Mrs. Veeranuch Thammavaranucupt. The proxy for the major shareholder, the Ministry of Finance, is Mr. Phuriwan Thaweesit, and Mr. Chanvit Prachayapipat from TTT & Partners Company Limited, who served as a witness for the vote-counting verification.

With respect to the documents used for the Meeting today, PTT had published such documents on its website and notified the publication to the Stock Exchange of Thailand ("SET") on March 13, 2025.

In order to promote good corporate governance and equitable treatment of its shareholders, PTT had informed shareholders via the SET and published an announcement on its own website to invite shareholders to propose significant matters to be included in the Meeting agenda of the 2025 Annual General Meeting of Shareholders and to nominate individuals whose qualifications were appropriate and met the criteria prescribed by PTT to be elected as directors during the period from September 1, 2024 to December 1, 2024. However, no shareholders proposed any agenda item, nor did they nominate any person in accordance with the prescribed criteria.

To ensure that the Meeting was convened smoothly, the Chairman asked the Company Secretary, Mrs. Pilasphan Udomjarumanee, to expound on meeting procedures to shareholders.

Mrs. Pilasphan Udomjarumanee explained the method for counting the votes of shareholders, who shall vote on each agenda item, as follows:

• A shareholder shall have voting rights equal to the number of shares held or represented by proxy, and may cast votes of approval, disapproval, or abstention on each agenda item equivalent to the number of shares which he/she or a proxy grantor held.

• To count votes, votes of disapproval or abstention, as well as the votes on invalid ballots (if any) would then be deducted from the total number of votes of the shareholders present at the Meeting, and the

  remaining numbers would be treated as votes for the approval of that agenda item. The vote counting shall be conducted as follows: (According to Public Limited Companies Act B.E. 2535)

• Agenda items that require a majority vote of the shareholders present at the Meeting and entitled to vote are:

  Agenda Item 2: To approve the financial statements for the year ended December 31, 2024

  Agenda Item 3: To approve 2024 net profit allocation and dividend payment

  Agenda Item 4: To appoint the auditors and approve the audit fees for the year 2025

  Agenda Item 6: To elect directors to replace those who are retired by rotation

  for the vote count, only the votes of shareholders present at the Meeting and voting either in favor or against will be counted. For Agenda Item 6 regarding the election of directors to replace those retiring by rotation, PTT will request shareholders to vote on an individual basis in accordance with the guidelines for the assessment of good shareholders' meeting practices.

• Agenda items that require a vote of not less than two-thirds of the total votes of the shareholders present at the Meeting are:

Agenda Item 5: To approve the 2025 directors' remuneration

The voting base will be calculated by counting the votes of shareholders who attend the Meeting and cast votes in favor, against, and abstain.

Ballots are invalid in cases where the shareholder appoints a proxy and specifies his/her votes in advance, but his/her declared intention is unclear, for example, they specify to vote in more than one box, and PTT is unable to verify such intention to vote of the shareholder. In any case, if the majority of votes cast were for approval in accordance with the PTT's Articles of Association regarding voting, it would be deemed that the Meeting had assented to or approved of such agenda item and provided voting instructions via a video presentation outlining the voting procedures by PTT.

Mrs. Pilasphan explained the method for voting via electronic means (e-Voting system) as follows:

1. For each agenda item, the voting system will display three voting options: Approve, Disapprove, and Abstain. Shareholders may change their vote at any time before the voting for that agenda item is officially closed.

2. In the case where a proxy is appointed by several shareholders, the system will display a list of all shareholders appointing such proxy to attend the Meeting. The proxy can choose to vote according to the list of shareholders who granted a proxy individually. Except in the case where the grantors have already specified their voting preference in advance in the proxy form, the system will display the voting as specified in the proxy form.

3. Shareholders must be present at the Meeting until the end of each agenda item and must vote on each agenda item before the closing of voting for that agenda item. In the event that the shareholder presses confirm button to leave the Meeting without voting in advance, before closing the voting of any agenda item,
