Mergers and Acquisitions in Thailand

Mergers and acquisitions in Thailand involve complex legal, regulatory, and transactional considerations governed by both civil law principles and a range of sector-specific regulations. The process of acquiring or merging with a Thai entity—whether public or private—requires a deep understanding of the Civil and Commercial Code (CCC), Public Limited Companies Act, Foreign Business Act, Trade Competition Act, and the Securities and Exchange Act, among others.

Unlike in many common law jurisdictions, mergers in Thailand are not broadly codified as a single legal mechanism; instead, transactions are generally executed through share purchases, asset transfers, or corporate restructuring under specific statutory provisions. Legal due diligence, foreign ownership limits, competition approval, and regulatory disclosures all play pivotal roles in shaping deal strategy.

This article provides a detailed legal and procedural analysis of M&A transactions in Thailand, including legal mechanisms, regulatory approvals, foreign investment considerations, and risk allocation in cross-border deals.

1. Legal and Institutional Framework

1.1 Key Statutes

Civil and Commercial Code B.E. 2468 (1925) — governs private limited companies, asset sales, contracts
Public Limited Companies Act B.E. 2535 (1992) — governs public companies and shareholding regulations
Foreign Business Act B.E. 2542 (1999) — restricts foreign participation in certain sectors
Trade Competition Act B.E. 2560 (2017) — merger control and antitrust regulation
Securities and Exchange Act B.E. 2535 (1992) — applicable for listed companies
Revenue Code — tax consequences of share and asset transfers

1.2 Regulatory Bodies

Department of Business Development (DBD) – registration of company changes and mergers
Securities and Exchange Commission (SEC) – capital markets regulation
Office of Trade Competition Commission (OTCC) – merger control
Bank of Thailand (BOT) and other sectoral regulators – where applicable

2. Common M&A Structures in Thailand

2.1 Share Acquisition

Most common method of acquiring control of a Thai company
May involve purchase of all or majority shares in a private or public company
Subject to:
- Shareholder approval (if transfer involves a controlling stake)
- Foreign Business Act compliance (if buyer is foreign)
- Notification to DBD and update of shareholder register

🔍 Control thresholds: Shareholding of 50% or more typically constitutes control. Some decisions require 75% supermajority under company articles.

2.2 Asset Acquisition

Acquirer purchases specific assets and liabilities, not shares
Buyer assumes selected liabilities only (unless contractually agreed)
May require:
- Board and shareholder approval
- Novation or assignment of material contracts
- Transfer of licenses, permits, and land use rights

📌 Often used to avoid taking on legacy liabilities, but may be more complex in operational terms

2.3 Business Transfer or Entire Business Transfer (EBT)

Defined process under Thai Revenue Code and DBD guidelines
Transfers all business assets, rights, and obligations from seller to buyer
Tax-neutral in some cases if certain conditions are met

✅ Common for intra-group restructurings, especially where licenses and employees must be transferred

2.4 Statutory Mergers

Under Section 1238 of the CCC, two companies can merge to form a new legal entity
Or one company may absorb another (amalgamation)
Rarely used in practice due to legal rigidity, complex approvals, and potential transfer tax issues

3. Foreign Ownership Considerations

3.1 Foreign Business Act (FBA) Restrictions

Foreigners (including foreign-majority owned Thai companies) are restricted from engaging in certain business activities without a license or exemption
Annexes 1–3 of the FBA specify restricted sectors, such as:
- Services
- Retail/wholesale
- Construction
- Land trading

3.2 Circumvention and Nominee Structures

Use of Thai nominee shareholders to bypass FBA restrictions is prohibited and subject to criminal liability
Buyers must assess:
- Whether target business activities require a Foreign Business License
- Whether BOI promotion or treaty exemptions (e.g., U.S. Treaty of Amity) apply

4. Public Company M&A and Capital Markets Regulations

4.1 Takeovers of Listed Companies

Subject to the Securities and Exchange Act and Takeover Rules, including:

Mandatory Tender Offer (MTO) if acquiring more than 25%, 50%, or 75% of total voting rights
Filing of a Tender Offer Statement (Form 247-4)
Disclosure obligations to the SEC and the Stock Exchange of Thailand (SET)

4.2 Insider Trading and Disclosure

Directors and major shareholders are subject to insider trading rules
Material events must be disclosed immediately to the SET
Voting and fairness opinions may be required if conflict of interest exists

5. Competition Law and Merger Control

The Trade Competition Act B.E. 2560 governs merger control in Thailand. A merger must be notified or approved depending on the thresholds.

5.1 Merger Notification (Post-Transaction)

Required if:
- The merger does not create dominance, but the combined turnover of the businesses exceeds THB 1 billion
Must be notified to OTCC within 7 days of completion

5.2 Merger Pre-Approval

Required if:
- The merger results in a dominant market position, defined as:
  - Market share ≥ 50% and
  - Turnover > THB 1 billion
Approval may take several months, with possible conditions imposed

5.3 Exemptions

Intra-group restructurings
Joint ventures not constituting an independent business entity

6. Tax and Stamp Duty Implications

6.1 Share Purchases

Capital gains tax may apply to seller
No VAT
Stamp duty of 0.1% of the transfer price or par value (whichever is higher), payable by the buyer

6.2 Asset Sales

VAT (7%) on sale of assets (except shares or land)
Transfer fees and specific business tax on land and building sales
Possible withholding tax on service-related contracts

6.3 Business Transfers and EBTs

May be tax-exempt if approved under Section 74 bis of the Revenue Code and other criteria are met

7. Due Diligence and Transaction Documents

A standard M&A transaction in Thailand requires:

Legal, financial, and tax due diligence
Share Purchase Agreement (SPA) or Asset Purchase Agreement (APA)
Representations and warranties (R&W) with local law qualifiers
Closing deliverables: shareholder resolutions, DBD filings, tax clearances
Transitional services agreements (if business continuity is needed)

Due diligence focuses on:

Title to shares or assets
Compliance with FBA and other laws
Pending litigation or tax issues
Corporate governance and contracts

8. Employment and Labor Considerations

Employment contracts do not transfer automatically in an asset deal
Must terminate and rehire, or obtain consent to transfer contracts
For business transfers under the Labor Protection Act, employees retain seniority and benefits
Works council or labor union consultation may be required

9. Common Pitfalls and Legal Risks

Failing to identify regulatory approvals needed before closing
Overlooking sector-specific restrictions, especially in services or manufacturing
Improper valuation or accounting for tax purposes
Using nominee structures, which can result in criminal liability and loss of investment
Non-compliance with merger control, which may result in fines or orders to unwind the transaction

10. Conclusion

Mergers and acquisitions in Thailand are governed by a multi-jurisdictional legal landscape that requires careful structuring, regulatory navigation, and contractual safeguards. Whether entering through share acquisition, asset transfer, or statutory amalgamation, parties must take into account foreign ownership restrictions, merger control requirements, tax implications, and due diligence findings.

Cross-border transactions further necessitate alignment with international accounting, anti-bribery, and data privacy norms, making M&A a legally intensive process that demands localized expertise.
