Bangkok, 15 October 2026 – The Securities and Exchange Commission (SEC) has revealed the imposition of civil sanctions on 14 offenders for colluding to manipulate the share price or trading volume of Chu Kai Public Company Limited (CRANE). Consequently, the offenders are required to pay civil monetary penalties totaling 43,600,952.54 baht, and are suspended from trading securities or derivatives, as well as barred from serving as directors or executives for specified periods.

Following a referral from the Stock Exchange of Thailand (SET) and the SEC’s further investigation, the findings and evidence indicated that during 15 May - 13 August 2020, the 14 offenders, who were interconnected through personal relationships, relationships arising from their patterns of opening securities trading accounts or placing trading orders, and financial relationships, namely (1) Mr. Thongchai Pairrungsri, (2) Miss Jiraluck Pairrungsri, (3) Mr. Rachata Khongbun, (4) Mr. Wut Borvornjirapat, (5) Mr. Peera Dumrongmahasawat, (6) Mrs. Sirirat Jarusombuti, (7) Miss Kaewjai Limpisuk, (8) Miss Kanit Limpisuk, (9) Mr. Phahon Limpisuk, (10) Miss Ueamporn Saekwang, (11) Mr. Thanespol Xu, (12) Miss Sirikorn Kongboon, (13) Mr. Thapanat Limthongsittikun, and (14) Mr. Nuttapol Ngamlao, jointly, through a division of roles, manipulated the price or trading volume of securities by placing buy or sell orders for securities, or buying or selling securities, in such a way that misleads other persons regarding the price or trading volume of the securities on a continued basis with the intent to cause the price or trading volume of the securities to be inconsistent with normal market conditions.
