Thailand's Securities and Exchange Commission (SEC) has issued a new regulation on material transactions (MTs) to govern asset acquisitions and disposals by listed companies and their subsidiaries. The new notification on MT criteria (No. TorJor. 45/2568) from the Capital Market Supervisory Board replaces the long-standing notification (No. TorJor. 20/2551) that has governed such matters. The SEC has also introduced parallel amendments to the country's related-party transaction rules.

The new regulation will take effect on July 1, 2026. Any MT matters approved by a company's board of directors for shareholders' approval before that date remain subject to Notification No. TorJor. 20/2551.
