Key Legal Framework for M&A in Thailand

M&A in Thailand is governed by several interlocking legal regimes and regulatory bodies, each of which may apply depending on the transaction type, the business sector, and the parties involved:

Civil & Commercial Code — Governs corporate transactions, asset transfers, and general contract law.
Public Limited Companies Act — Applies to public companies, addressing governance rules and merger/amalgamation requirements.
Securities and Exchange Act (SEA) — Regulates M&A for publicly listed companies, including tender-offer rules.
Foreign Business Act (FBA) — Restricts foreign ownership in certain sectors, affecting how acquisitions can be structured.
Trade Competition Act — Overseen by the Trade Competition Commission (TCC), this law reviews mergers that could significantly affect market competition.

In addition, industry-specific regulators may have a role in M&A transactions, especially in regulated sectors such as banking, insurance, energy, or telecommunications.

Common M&A Structures

When structuring a transaction in Thailand, there are several well‑established models:

Share Acquisition
One company buys equity in another, gaining control of the target’s assets and liabilities.
Asset Acquisition
Instead of buying the business as a whole, only specific assets are acquired, allowing the buyer to avoid certain liabilities.
Amalgamation
Two or more companies combine to form an entirely new entity (“A + B = C”), consolidating operations under a new legal structure.
Statutory Merger
One company survives, and the other is absorbed (“A + B = A or B”). Legal reforms have made this structure more flexible under recent amendments.

The M&A Process: Step by Step

Here’s a practical breakdown of how an M&A transaction typically unfolds in Thailand — and how BASE Law Firm supports you throughout:

Strategy & Planning
- Determine motives (growth, consolidation, exit)
- Decide on the appropriate structure (share deal, asset deal, merger)
- Identify regulatory and tax implications
Due Diligence
- Legal review: corporate documents, litigation, intellectual property, licenses
- Financial and tax assessment: financial statements, liabilities, tax exposures
- Regulatory compliance: FBA, competition, sector-specific approvals
Deal Structuring & Negotiation
- Negotiate terms: price, payment mechanism, conditions precedents
- Draft definitive documentation: Share Purchase Agreement (SPA), Asset Purchase Agreement (APA), or Merger Agreement
Regulatory Approvals
- File with the Department of Business Development (DBD) for structural changes.
- Obtain TCC approval when required under the Trade Competition Act.
- For listed companies, comply with Securities & Exchange Commission requirements (e.g., tender offers)
- Address Foreign Business Act constraints, especially for foreign participants.
Closing & Integration
- Transfer ownership, assets, or shares
- Update corporate records (shareholders, directors) with the DBD
- Implement integration plans: combine operations, systems, and governance
Post‑Closing Maintenance
- Ongoing regulatory compliance
- Governance alignment, risk management, and reporting
- Execution of any agreed holdbacks, indemnities, or escrow mechanisms

Risks & Considerations in Thai M&A

M&A in Thailand is laden with unique challenges, many of which require local legal insight:

FBA Restrictions: Foreign investment limits in certain sectors may require special licensing or structuring.
Competition Risk: TCC review may delay or condition the transaction.
Due Diligence Gaps: Insufficient investigation can expose buyers to hidden liabilities, such as undisclosed litigation or unpaid taxes.
Cultural & Management Integration: Aligning two corporate cultures and workflows post-merger may be challenging.
Sector‑Specific Regulation: Companies in heavily regulated industries may face additional approval requirements from sector regulators.

Tax Implications

Structuring M&A in a tax-efficient way is vital. Key tax issues include:

Stamp duty may apply to certain share transfers.
For public companies, witholding tax or other tax obligations may arise depending on the transaction structure.
M&A models (e.g., business transfers or mergers) are often assessed for tax treatment under Thai Revenue Department regulations.
