PTT's board raised the interim dividend ceiling to about 39,989 million baht to cover a possible sale of all 238.66 million shares it bought back. The rate stays at 1.40 baht per share, and the record date is 8 October 2026. Only shares held on the record date receive dividends. For a small Thai business this is an investment-market update with no direct action needed, unless you hold PTT shares.
