In brief
The Stock Exchange of Thailand (SET) has introduced new standalone regulations and interpretative guidelines on backdoor listing and cash company in connection with the recent updates to the Capital Market Supervisory Board's material transaction (MT) rules. The amendments aim to maintain investor protection and ensure equivalent SET listing standards for indirect listings. Although the substantive requirements remain largely unchanged, the regulations provide greater clarity on the SET's approach to assessing these matters. Please see our previous newsletter, Thailand: SEC Material and Connected Transaction Rules in February 2026, for more details.
Key takeaways
- Greater emphasis on substance over form of the backdoor listing – The SET will assess transactions based on their commercial substance, overall objective and ultimate outcome, rather than solely on their legal structure or technical compliance with prescribed thresholds. The guidelines identify circumstances that may indicate an attempt to circumvent the backdoor listing rules, such as transaction splitting, partial acquisitions, the use of intermediary entities, and complex structures lacking a clear commercial rationale. The SET will also evaluate changes to the listed company's principal business, revenue profile, assets, management, shareholders, control structure, and the interrelationship of multiple transactions.
- Focusing on the operational substance of the listed cash company – The SET will consider not only a company's cash position, but also its business activities, revenue-generating operations, assets used in the business and overall operating capability. Listed companies with significant cash reserves may not necessarily be regarded as cash companies if they continue to operate an active business.
