MSC International Law Office provides end-to-end M&A legal advisory to investors, entrepreneurs, and corporations operating in or entering the Thai market.
What Is M&A (Mergers & Acquisitions)?
Mergers and Acquisitions (M&A) refers to the consolidation of companies or assets through various types of financial transactions, including mergers, acquisitions, consolidations, tender offers, purchase of assets, and management acquisitions.
Key Definitions
Understanding key M&A terminology is essential for structuring and executing transactions effectively. Below are the core concepts commonly used in mergers and acquisitions, particularly in the context of Thailand.
- Merger — Two companies combine to form a single new entity, and both original companies cease to exist.
- Acquisition — One company (acquirer) purchases another (target), which may continue to operate as a subsidiary.
- Amalgamation — Under Thai law (Civil and Commercial Code, amended February 2023), two or more companies merge into one surviving entity.
- Asset Deal — The buyer acquires specific assets (and potentially liabilities) instead of purchasing shares of the company.
- Share Deal — The buyer acquires shares of the target company and assumes its rights, obligations, and liabilities.
- Due Diligence — A comprehensive legal, financial, and operational review conducted before completing the transaction.
- Tender Offer — A public offer to purchase shares from existing shareholders, typically in acquisitions of listed companies.
- Joint Venture (JV) — Two or more parties establish a new entity to pursue a shared business objective.
Types of M&A Structures Under Thai Law
- Amalgamation — Both companies dissolve; a new company is formed (e.g., Company A + B = Company C).
- Merger — One company absorbs another; the surviving entity retains its legal identity (e.g., A + B = A or B).
- Share Acquisition — Acquirer buys existing shares from shareholders.
- Asset / Business Transfer — Acquirer purchases specific assets or an entire business unit.
- Joint Venture Formation — Parties form a new company to operate jointly.

Frequently Asked Questions
Under Thai law, M&A transactions can take the form of a merger (where one company absorbs another), an amalgamation (where two companies dissolve to form a new entity), a share acquisition, or an asset/business transfer. Since February 2023, the Civil and Commercial Code was amended to introduce the merger scheme alongside the pre-existing amalgamation scheme, giving parties greater structural flexibility.
Regulatory requirements depend on the nature and size of the transaction. The Trade Competition Commission of Thailand (TCCT) requires notification if the transaction may result in a monopoly or substantial reduction in competition. Sector-specific transactions (banking, insurance, telecom) require approval from their respective regulators. Foreign investors must also assess Foreign Business Act compliance and BOI eligibility.
Legal due diligence is the systematic review of a target company's legal standing before transaction completion. It covers corporate documents, material contracts, employment obligations, litigation risk, intellectual property, real property, regulatory licences, and environmental compliance. The findings inform deal pricing, warranty coverage, and indemnity provisions in the purchase agreement.
In a share deal, the buyer acquires the shares of the target company and inherits all its assets, liabilities, rights, and obligations. In an asset deal, the buyer selects specific assets (and agreed liabilities) to purchase, typically offering greater liability protection. Asset deals may trigger higher stamp duties and require more complex consent processes for contract transfers. The optimal structure depends on tax efficiency, liability exposure, and regulatory considerations.
Timeline varies significantly by transaction complexity. A straightforward private share acquisition may close in 6–12 weeks from term sheet to closing. Transactions requiring TCCT merger notification, Foreign Business Licences, or public company tender offers may take 4–12 months or longer. Early legal engagement significantly reduces timeline risk.
- Undisclosed liabilities — litigation, tax, environmental, and employment obligations.
- Foreign ownership restrictions under the Foreign Business Act, particularly in restricted business categories.
- Change-of-control clauses in key contracts that may trigger consent requirements or termination rights.
- IP ownership gaps — where trademarks, patents, or domain names are not properly registered to the target.
- Regulatory licence transferability — some licences are not transferable and must be re-applied for.
- Post-closing disputes arising from warranty breaches or earn-out disagreements.
Foreign ownership is regulated by the Foreign Business Act B.E. 2542. In most general industries, foreigners may own up to 49% of a Thai company without a Foreign Business Licence. However, BOI-promoted companies, Treaty of Amity companies (US nationals), or FBL holders may be permitted to hold majority or full ownership. Legal structuring and regulatory compliance advice is essential before any cross-border acquisition.
