SEC requests public prosecutor to file a civil lawsuit against an offender in the Civil Court for manipulating the price or trading volume of RPC shares



Monday 2 March 2026 | No. 49 / 2026


Bangkok, 2 March 2026 – The Securities and Exchange Commission (SEC) has requested
the public prosecutor to file a civil lawsuit against an offender, namely Mr. Suthee Siripornpitak, for manipulating the price or trading volume of RPCG Public Company Limited (RPC) shares to seek an imposition of civil sanction with the maximum applicable statutory penalties.

Earlier, the Civil Sanction Committee (CSC) resolved to impose civil sanctions on two offenders* in the case of manipulating the price or trading volume of RPC shares. The sanctions include a total payment of 71,729,832 baht (comprising civil penalties, compensations in the amount equal to the benefits received or should have been received, and reimbursements of investigative expenses incurred by the SEC). In addition, the offenders are subject to a suspension from trading securities and derivatives for 14 months or 8.5 months, as the case may be, and a bar from serving as directors or executives for 28 months or 17 months, as the case may be.

In this regard, while one offender agreed to comply with the civil sanctions imposed by the CSC, Mr. Suthee Siripornpitak, refused to do so, which is deemed a refusal to resolve the case at the SEC level.

Accordingly, the SEC has submitted a written request to the public prosecutor for filing a lawsuit against Mr. Suthee in the Civil Court to seek the imposition of civil sanctions requiring him to pay a total amount of 94,643,271.70 baht plus interest, and to impose a suspension on Mr. Suthee from trading securities and derivatives, as well as a bar from serving as a director or executive, at the maximum statutory penalties.

In addition, the SEC has referred this matter to the Anti-Money Laundering Office (AMLO) for further action within its authority, as the unfair securities trading misconduct constitutes a predicate offense under the Anti-Money Laundering Act B.E. 2542 (1999).
