Mergers and acquisitions in Thailand are governed by a patchwork of laws that reflect the country’s civil law tradition, sectoral regulatory structure, and foreign investment controls. While Thailand offers a dynamic and strategic market for M&A activity—particularly in sectors like manufacturing, energy, real estate, and technology—transactional success hinges on navigating legal restrictions, corporate governance procedures, and regulatory approvals.
This article provides a comprehensive, legally grounded overview of M&A in Thailand, including applicable statutes, deal structures, regulatory oversight, foreign ownership restrictions, tax implications, and practical procedural requirements.
1. Legal and Regulatory Framework
1.1 Key Legislation
- Civil and Commercial Code (CCC) – Company law, including rules for share purchases, amalgamation, and board approvals
- Public Limited Companies Act B.E. 2535 (1992) – Governs M&A involving public companies
- Foreign Business Act B.E. 2542 (1999) – Restricts foreign participation in certain sectors
- Trade Competition Act B.E. 2560 (2017) – Merger control and anti-trust law
- Securities and Exchange Act B.E. 2535 (1992) – Regulates listed company takeovers via the Takeover Rules issued by the SEC
- Revenue Code – Tax implications of asset and share transfers
2. M&A Deal Structures in Thailand
M&A in Thailand typically follows one of the following legal structures, each with different legal and tax consequences:
2.1 Share Acquisition
- Acquisition of shares in a target company from existing shareholders
- Most common structure due to simplicity and continuity
- Acquirer assumes indirect ownership of target’s assets and liabilities
- Share transfer must be registered with:
- Company Registrar (for shareholding changes)
- Ministry of Commerce (DBD)
Foreign acquirers must assess whether share acquisition triggers foreign majority status under the FBA.
2.2 Asset Acquisition
- Direct purchase of a company’s business assets, contracts, and goodwill
- Seller retains the legal entity and liabilities unless contractually transferred
- Requires:
- New contracts or assignment of contracts
- Land office registration (for immovable assets)
- VAT implications
2.3 Business Transfer (Entire Business Transfer – EBT)
- Transfer of entire business under Section 107 bis of the Revenue Code
- Used for tax efficiency and liability control
- Requires:
- Tax clearance
- Shareholder approval (special resolution)
- Formal notice to authorities and creditors
2.4 Amalgamation or Merger
- Two or more companies combine to form a new legal entity or merge into one surviving entity
- Regulated under CCC (for private companies) and Public Company Act (for listed companies)
- Requires:

- Tax and employment law compliance
Recent amendments (2023) allow merger by absorption under the CCC—a structure not previously permitted.
3. Regulatory and Sector-Specific Approvals
Depending on the nature of the target and the acquirer, regulatory approvals may be required from:
3.1 Department of Business Development (DBD)

- Change in shareholding for foreign-majority companies
3.2 Foreign Business License (FBL)
- If post-acquisition control shifts to foreign-majority, and business is restricted under the Foreign Business Act, an FBL must be obtained
3.3 Securities and Exchange Commission (SEC)
- For listed companies
- If acquisition exceeds 25%, 50%, or 75% of voting rights, triggers mandatory tender offer (MTO)
- Takeover rules under Notification SorJor. 12/2543
3.4 Trade Competition Commission

Conclusion
Mergers and acquisitions in Thailand are governed by a multi-jurisdictional and sector-sensitive legal environment, requiring thorough due diligence, strategic structuring, and compliance with regulatory, tax, and corporate governance obligations.
Whether a deal involves a domestic target, a cross-border acquisition, or a foreign-controlled Thai entity, parties must carefully assess the implications under the Foreign Business Act, competition law, and corporate statutes, as well as ensure transactional documents are aligned with both Thai law and commercial expectations.
A successful M&A deal in Thailand is less about speed and more about strategic risk management, local legal insight, and regulatory navigation.
