Thailand’s Securities and Exchange Commission (SEC) has overhauled its approach to related-party transactions (RPTs) by issuing new rules that simplify approval processes while expanding oversight. Capital Market Supervisory Board Notification No. TorJor. 46/2568 will replace the longstanding Notification No. TorJor. 21/2551, which has governed RPT compliance for over a decade. The new regulation takes effect on July 1, 2026. Any RPT matters approved by a company’s board of directors or approved for shareholders’ approval before that date remain subject to Notification No. TorJor. 21/2551. The new RPT rules will introduce significant changes that market participants should carefully consider. Consolidated Definitions Under the previous framework, key definitions relevant to RPT compliance were dispersed across multiple sources, including SEC notifications, Stock Exchange of Thailand (SET) regulations, and provisions of the Securities and Exchange Act (before amendments). The new regulation consolidates these definitions into a single notification. Concepts such as “related party” and “connected person,” as well as relevant transaction categories, are now more systematically organized and written in greater detail. The SET has yet to issue corresponding regulations, which should include more detailed related disclosure requirements. Unified Threshold and Mandatory Board Approval The most significant change under the new regulation is the elimination of the multitiered approval framework based on transaction type. Instead of various categories, transactions are now classified as either (1) financial assistance provided to related persons, or (2) other RPTs in order to determine the level of corporate approvals and disclosures for each transaction size in these categories, but the concept remains the same. Under the previous regulation, RPTs were divided into small, medium, and large transactions, with differing approval requirements. The new regulation effectively merges the small and medium categories. As a result, all RPTs must now be approved by the board of directors as a baseline

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. Following that date, the new MT rules will introduce several significant changes that market participants should carefully consider. Expanded Scope of Material Transactions One of the key changes under the new regulation is the expansion of the definition of MTs, which now expressly covers financial assistance and certain lease and business lease arrangements that are not in the ordinary course of business of the listed company or its subsidiaries. For financial assistance, this includes lending, granting credit, providing guarantees, or entering into any arrangement that increases the company’s financial obligations, particularly where the recipient is facing liquidity issues or unable to repay debts. Other forms of financial support also fall within scope. However, whether the provision of collateral for others qualifies as an MT remains somewhat unclear, since no disposal of assets occurs for the provider of collateral. This issue remains to be carefully considered. For lease-related transactions, the MT rules now specifically include the lease or hire-purchase of all or part of a business or assets operated by or belonging to a listed company or its subsidiaries. New Exemptions The new regulation introduces clearer exemptions for transactions between a listed company and its subsidiaries or among subsidiaries, which

As the Thai stock market faces a downturn, Thai investors have shown increased interest in depositary receipts (DRs), which offer the same tax benefits as Thai stocks while providing access to foreign securities. However, recent speculation in the media has raised concerns among regulators and the market, raising questions about whether DR issuers actually hold the underlying foreign securities purported to be backing the DRs. This has brought the structural integrity of DR programs under scrutiny. Why This Question Matters In global practice, DRs are understood to be backed by the foreign securities they reference, giving investors economic exposure that closely mirrors direct ownership. When the issuer does not hold the underlying securities directly, the risk profile shifts to the strength of its custodial, hedging, and liquidity arrangements. Those arrangements determine whether DR holders receive equivalent economic and voting rights, how corporate actions are transmitted, and whether conversions or redemptions can be completed in full and on time. In Thailand, the standardized DR disclosure templates and the express allowance for global custodians indicate a regulatory focus on transparency and structural safeguards that preserve these outcomes, even if the issuer’s name does not appear on the foreign share register. Thai Rules for DR Offerings Thai DR offerings are governed by specific Securities and Exchange Commission (SEC) notifications and standardized prospectus forms. These instruments establish the disclosure regime for DR structures, risk factors, and the issuer’s arrangements to support the DR program. The framework expressly contemplates the use of a global custodian, indicating that DR issuers are not required to hold the underlying foreign securities directly in their own name if sufficient controls and operational arrangements are in place for the issuer to deliver economic benefits and, where applicable, underlying securities to DR holders when required. More broadly, the relevant SEC

Recent events at a Thai listed company, where a proposal to remove the director was not successful, amid claims that a competitor was attempting to gain control of the company, illustrate how disputes over corporate control can unfold differently at the board level and shareholder level. At the board level, removing directors of a listed company mid-term to gain corporate control is not an easy task under Thai law, as it requires a higher threshold than appointing a new director, which typically only requires a simple majority vote in a listed company. At the shareholder level, Thailand’s tender offer and competition regimes add complexity where different shareholder groups act in concert to remove opposing board representatives or otherwise influence control. In this article, we will explore why the attempted removal of a director may fail, and how the tender offer regime may apply. Key Issues at a Glance Shareholder groups may seek to convene meetings to propose changes to board composition or company authority. Such proposals can be delayed or complicated by regulatory requirements and the need for additional disclosures. Regulatory authorities and minority shareholders may raise concerns when major shareholders coordinate to influence board control, especially if such actions could trigger tender offer or merger control obligations. Companies often respond by seeking further information on shareholder relationships and potential conflicts before proceeding. Why the Director Removal Failed Under Section 76 of the Public Limited Companies Act B.E. 2535 (as amended), the early removal of a director requires two conditions to be satisfied at the same meeting of shareholders: Headcount test: At least 75% of shareholders attending and entitled to vote must vote in favor. If multiple shareholders appoint the same person as proxy, each proxy is counted as a separate head for the purpose of the headcount test,
