A merger or acquisition (M&A) is often the fastest way to establish foothold in Thailand. It allows you to instantly acquire customers, technology, and market share.
However, as with any major business move in Thailand, your success hinges on navigating the local rules. Mainly, you will need to tackle key regulations on foreign ownership and market competition.
In this article, we will discuss mergers and acquisitions in Thailand and outline the steps to help you ensure your M&A is both smart and compliant.
Understanding Common Mergers and Acquisitions Pathways in Thailand
In Thailand, M&A isn’t always a complex merger of two giants. For most foreign investors, the process involves a few common pathways. Understanding these options is the first step in structuring your deal.
- Share Acquisition: This is the most common route. Basically, you buy shares in a Thai company directly from its owners. It’s often the simplest and fastest way to get a deal done, whether you’re buying a small stake or acquiring full control.
- Asset or Business Transfer: Instead of buying the company, you can buy its assets. This could be its factory, brand, or customer lists. This path can be a smart way to avoid taking on a company’s hidden debts or legal issues. However, the process itself can be more complex, as each asset might need to be transferred individually.
- Amalgamation (Legal Merger): This is the classic merger where two companies legally combine into one. In Thailand, this is a formal, court-supervised process. Because it’s complex and time-consuming, it’s much less common and typically only used for large-scale corporate restructurings.
Key M&A Regulations in Thailand
Once you have a target company in sight, you must navigate two main sets of regulations that govern M&A transactions in Thailand.
1. Foreign Ownership Restrictions Under the Foreign Business Act
The first hurdle you’ll likely face is the Foreign Business Act (FBA). This law can be a major challenge because it generally limits foreign ownership to 49% in most business sectors. A standard acquisition, therefore, would leave you as a minority shareholder.
However, there are established and legal pathways to achieve 100% foreign control:
- Board of Investment (BOI) Promotion: If your business is in an industry that the Thai government promotes, you can apply for BOI status. This is a preferred solution, as it can grant you an exemption from the 49% limit, for 100% foreign ownership.
- Foreign Business License (FBL): For some businesses not covered by the BOI, it’s possible to apply for a Foreign Business License. While the process for an FBL is demanding, if successful, you will be able to have majority or full control of the company as a foreigner.
- U.S.-Thai Amity Treaty: If you’re an American citizen or a US based company, you can have majority ownership in most sectors under this treaty.
2. Competition Law
Thailand’s has a Trade Competition Act which is to prevent monopolies and ensure fair market practices in the country. The act is overseen by the Trade Competition Commission (TCC).
If you are planning a large M&A transaction that could significantly reduce market competition, you may need to get pre-merger approval from the TCC.
If your deal falls into this category, you cannot complete the transaction without TCC clearance. The review process takes approximately 90 days, during which the TCC can approve, deny, or impose conditions on the deal.
It is advisable to consult our local experts who will guide you through these regulations and help to ensure a successful M&A.
Conducting Due Diligence to Protect Your Investment
In a market like Thailand, where you may not be familiar with all the local practices, you cannot afford to make assumptions. That’s why it’s strongly recommended to conduct thorough due diligence before moving ahead with an M&A deal.
Through due diligence protects your investment by uncovering potential risks. Since you go beyond the surface-level numbers, you get to see the true picture of company’s health.
Your due diligence should cover three critical areas:
- Financial Health: Check company’s financial records to verify its profitability and uncover any hidden debts or unexpected tax liabilities
- Legal and Corporate Standing: You need to review all major contracts and licenses to ensure the company is legally compliant. You should also check for any pending litigation and verify the company’s official records with the Department of Business Development (DBD).
- Company Operations: look at the stability of its supply chain, its dependency on key employees or customers, and the condition of its technology and assets.
I know It can be tempting to move quickly when a promising M&A opportunity arises. However, skipping due diligence process is one of the biggest and most costly mistakes an investor can make.
Companies House in Thailand gives you access to important corporate information. You can verify your target company’s legal status, ownership structure, shareholder details, capital, and historical filings. The registry data supports legal due diligence by confirming compliance with Thai corporate laws and identifying potential legal liabilities.
