PTT Public Company Limited ("PTT") opted to use an electronic meeting control system provided by PTT Digital Solutions Company Limited, a service provider who is assessed on the consistency of the meeting control system by the Electronic Transactions Development Agency (ETDA) as a standardized service provider in accordance with Emergency Decree on Electronic Meetings, B.E. 2563 (2020) and Notification of the Ministry of Digital Economy and Society re: Standards for Maintaining Security of Meetings via Electronic Means (2020), as well as the relevant laws and regulations. In this regard, PTT recorded the 2023 Annual General Meeting of Shareholders in video format in order to disseminate it to attendees to rewatch later via PTT's website.

Before the Meeting

PTT presented an introduction video, explaining attendance of the meeting via electronics means, as well as the voting methods via e-Voting system and the process for asking questions via electronic means.

Commencement of the Meeting

On March 3, 2023, which was the Record Date determining the shareholders' entitlement to attend the Meeting and receive dividends, PTT had registered paid-up capital of THB 28,562,996,250, representing 28,562,996,250 issued ordinary shares, in total, with a par value of THB 1 per share. At the outset of the Meeting, a total of 1,996 shareholders and proxies attended the meeting via electronic means. Of these, 138 shareholders attended the Meeting in person and 1,858 shareholders attended by proxy, representing a total of 22,671,052,957 shares, equivalent to 79.3721 percent, which was more than one-third of the total issued shares of PTT, thus constituting a quorum pursuant to PTT's Articles of Association. It was noted that PTT continued to accept the registration of shareholder attendance thereafter.

Prof. Dr. Thosaporn Sirisumphand, Chairman of PTT's Board of Directors, presided as the Chairman of the Meeting and gave an opening speech to the 2023 Annual General Meeting of Shareholders. He welcomed all shareholders to the 2023 Annual General Meeting of Shareholders which marked the 22nd anniversary of PTT's listing on the Stock Exchange of Thailand on December 6, 2001 and thanked all shareholders for their continued trust, and proclaimed that PTT was an organization that operated a fully-integrated energy business and was Thailand's leading energy

company with good governance, transparency and auditability, focusing its efforts on increasing operational efficiency in order to provide maximum benefits to all stakeholders in an equitable manner.

He also noted that PTT was recognized in the Dow Jones Sustainability Indices (DJSI World Index) for the eleventh consecutive year, and that the NACC Integrity Awards 2022 was bestowed upon PTT by the National Anti-Corruption Commission, testament to PTT's continued commitment to good corporate governance and professional ethics. PTT is determined to contribute towards society, the community and the environment. It aims to be one of the driving forces behind the country's development, and to operate with a sense of pride, promoting transparency for sustainability.

The Chairman then introduced directors and executives who attended the Meeting, 18 persons in total, as follows.

Directors(the directors attending the Meeting accounted for 100 percent of the total number of directors)

A total 14 directors attended the Meeting. Given that M.L. Chayotid Kridakon, an independent director, announced his resignation from directorship on March 22, 2023, this accounted for 100 percent of the directors. The Chairman also informed attendees that the vacancy arising from M.L. Chayotid Kridakon's sudden resignation, will be be filled without delay, according to legal procedures.

Executive Officerswere as follows.

In addition, there were other executive officers at the level of Senior Executive Vice President and Executive Vice President on standby to provide clarification and information in answer to any questions raised. Three Independent Directors present at the Meeting, namely Gen. Teerawat Boonyawat,

informed shareholders via the Stock Exchange of Thailand and published an announcement on its own website to invite shareholders to propose matters to be included in the meeting agenda of the 2023 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, 2022 to November 30, 2022. However, no shareholders proposed any agenda item, nor did they nominate any person in accordance with the prescribed criteria.

The Company Secretary informed the Meeting of the Methods for Vote Counting and Voting via Electronic Means

To ensure that the Meeting was convened smoothly, the Chairman asked the Company Secretary, Mr. Nisit Phongvutiprapant, to expound on meeting procedures to shareholders.

Mr. Nisit Phongvutiprapant would like to clarify vote-counting procedures for each agenda item for the shareholders to acknowledge as follows.

• A shareholder 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 voting base would be calculated from the aggregate number of votes of shareholders present and entitled to vote. With respect to Agenda Item 6 regarding the appointment of directors to replace the directors retiring by rotation, shareholders would be asked to cast their votes for each candidate on an individual basis, in order to be consistent with guidelines on the Annual General Meeting Quality Assessment. Ballots are invalid in cases where the shareholder appoints a proxy and specifies his votes in advance, but his 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 PTT's Articles of Association regarding voting, it would be deemed that the Meeting had assented to or approved of such agenda item.

Mr. Nisit would like to clarify on the method for voting via electronic means (e-Voting system) as follows.

1. A shareholder wishing to vote must vote in the e-Voting system, whereby the shareholder attending in meeting via mobile phone and tablet can access the voting system through the link sent to the shareholders via e-mail notifying information for attending the meeting, or through the link provided in the chat channel. For shareholders attending the meeting through computer equipment, voting can be logged in the Multimedia Viewer menu on the bottom right of the screen.
2. A shareholder must use their username and password to verify their identity in the voting system. The shareholders can choose the agenda they want to vote on and press the button to vote as desired. The system will display three buttons namely, agree, disagree and abstain. The system will display the status of the latest vote chosen by the shareholder. In any case, voting is subject to change until there is a notification to close voting on each agenda.
