Bangkok: The Stock Exchange of Thailand has taken decisive action by placing various marks on several listed companies, cautioning investors to meticulously review these indicators before proceeding with any investments. The move is part of an effort to maintain transparency and protect investors from potential financial risks associated with these securities.

According to Thai News Agency, the Stock Exchange of Thailand this morning placed a "SP" (Suspension) mark on the securities of companies that have failed to submit their financial statements by the March 31, 2026 deadline. These companies, listed on both the SET and mai markets, include AKS, CHO, CV, DEXON, ECF, HPT, KWI, META, MILL, MVP, NRF, and SAM. The SP mark indicates that trading of these securities is temporarily suspended, and the suspension extends beyond one trading session.

In addition to this, a CB (Confirmation of Trading) mark was placed on RS securities due to a default on debt payments according to the specified criteria. A similar CB mark was also added to PPPM securities because of losses sustained for three consecutive years. The CB mark serves as a cautionary sign to investors, highlighting that a company is currently facing financial or operational difficulties.

The primary reasons for a CB mark include below-average equity, sustained losses, low revenue, or defaults on debt payments. Companies are generally marked with CB after incurring losses for three uninterrupted years. Stocks with a CB mark must be traded via a cash balance account, which might reduce liquidity and lead to price volatility. It is advised that investors thoroughly investigate the underlying causes and monitor any progress in addressing these issues before making any investment decisions.
