This follows ACC’s submission of clarification letters regarding the allocation of PP offering, in a case where the SEC exercised its authority under Section 58(1) of the Securities and Exchange Act B.E. 2535 (1992) (SEA). Such information was disclosed to the public via SETLink on 1 April 2026* and 23 April 2026**, respectively. In addition, ACC published the notice calling the shareholders’ meeting via SETLink on 10 April 2026.

The SEC found that the information clarified and disclosed by ACC in the notice calling the shareholders’ meeting lacked material information and did not comply with the requirements under Clause 5(2)(b), Clause 5(4), and Clause 7(2) of the Notification of the Capital Market Supervisory Board No. Tor Jor. 73/2558 Re: Particulars of Notice Calling Shareholders’ Meeting of Listed Companies to Obtain Approval for Issuance and Offer of Securities for Sale, dated 28 October 2015, as well as the disclosure guidelines for the notice calling shareholders’ meeting as prescribed under the said notification. As a result, such offering constituted an offering of securities that was not in compliance with the Notification of the Capital Market Supervisory Board No. Tor Chor. 28/2565 Re: Approval for Listed Companies to Offer Newly Issued Shares through Private Placement. Accordingly, the SEC, pursuant to Clause 7(5) of the same notification, ordered the suspension of ACC’s PP offering.
