M&A Advisors in Thailand: How Mid-Market Deals Get Done

In Thailand a business worth between $2M and $50M is normally sold through one of five kinds of advisor: the corporate finance team inside a Big Four firm, a Bangkok corporate finance boutique, a Japanese-affiliated advisory house that sells Thai companies to Japanese acquirers, a general business broker, or an online listing site. What separates them is whether the advisor already controls a list of buyers with money and a reason to look at your sector, or whether they will publish your business and wait for the phone. KPMG's Thailand M&A tracker counted 57 transactions worth USD 7.9 billion in the first quarter of 2026, and one deal, Telenor's USD 3.9 billion sale of its True Corporation stake, carried half that value on its own. The market you are in is the long tail underneath that number.

The second thing to settle is legal rather than commercial. The Foreign Business Act B.E. 2542 treats a company as foreign once non-Thais hold 50% or more of its registered shares, and foreign companies are shut out of or restricted across three schedules of activities. So the question of who is allowed to buy your company comes before the question of who should sell it. An advisor who cannot tell you in the first meeting which list your business falls under, and therefore which buyers can own it outright, will cost you months.

Who actually advises on a $2M to $50M sale in Thailand?

Five groups compete for the same mandates and they are not substitutes for one another.

The Japanese row is there for a reason. Japanese companies applied for 119 billion baht of investment promotion in Thailand across 311 projects in 2025, up 146% in value and 17% in project count on 2024, according to Board of Investment figures reported by The Nation in 2026, led by automotive and parts at 28.3 billion baht and electronics at 24.3 billion baht. A Thai auto-parts maker with 120 staff and $6M of EBITDA sits inside the buying remit of a dozen Japanese groups that already own plants in Rayong and Chonburi, and an advisor with no Japanese-language capability will not reach them. A Bangkok services business selling to Thai customers is of no interest to those same buyers, and paying for a Japan-focused process would be money burned.

Global advisory firms rarely take mandates below $100M, and local brokers rarely hold a buyer network deep enough to run a genuinely competitive sale. Nobridge was built for the gap between them, with more than 500 qualified buyers across Asia-Pacific, Europe and North America. The trade-offs between a boutique and a global name are set out in our comparison of boutique and global advisory firms on mid-market deals.

How does the Foreign Business Act decide who can buy your company?

The Foreign Business Act B.E. 2542 (1999) shapes your buyer list before an advisor writes a page. A company counts as foreign once non-Thai persons or entities hold 50% or more of its registered shares, which is why the 49% structure is so common in Thai corporate registers. Three schedules attached to the Act, published in English translation by the Board of Investment, set what a foreign company may and may not do.

• List 1 is closed to foreigners outright. Newspapers and broadcasting, rice farming, land trading and a short list of others. No licence exists for these.
• List 2 covers activities touching national security, arts and culture, or natural resources. A foreign company needs Cabinet approval granted through the Minister of Commerce, and in the usual case at least 40% Thai shareholding.
• List 3 covers activities in which Thai nationals are treated as not yet ready to compete. Most services, wholesale, retail, construction and professional work sit here, and a Foreign Business Licence from the Department of Business Development is required.

Manufacturing is the important omission. Producing goods in Thailand is not a listed activity, so a foreign buyer can usually own a Thai factory outright, while the same buyer needs a licence to own the distribution company that sells its output. That one distinction does more to set the price of a Thai mid-market business than any multiple in a broker's brochure.

The Act sets minimum capital at no less than 2 million baht for a foreigner starting a business in Thailand, rising to 3 million baht for each activity that requires permission. Section 36 makes the workaround a criminal matter rather than a grey area: a Thai national or Thai company holding shares on a foreigner's behalf faces up to three years' imprisonment, a fine of 100,000 to 1,000,000 baht, or both. Nominee arrangements inherited from a previous owner are exactly what a careful buyer's lawyers find in diligence, and they reprice deals.

Two routes take a foreign buyer past the 49% ceiling. Under the 1966 Treaty of Amity and Economic Relations, US citizens and US-majority companies receive national treatment and may hold 100% of a Thai company, with carve-outs the US State Department lists as communications, transport, fiduciary functions, banking involving depository functions, exploitation of land and other natural resources, and domestic trade in indigenous agricultural products. The second route is BOI promotion: a promoted project can be up to 100% foreign owned, and the promoted company applies for a Foreign Business Certificate under Section 12 of the Act, which lifts the shareholding restriction for that activity. List 1 stays reserved either way.

If your business qualifies for either route, your buyer pool widens from Thai acquirers and 49% minority investors to anyone with capital. The application mechanics are set out in our guide to Thailand's Foreign Business Act and BOI incentives for acquirers.

What does a Thai mid-market deal look like mechanically?

Almost every transaction in this size range is a share sale of a Thai private limited company, the Co., Ltd. structure most family businesses use. The transfer paperwork itself is lighter than most owners expect. The surprises sit in the tax treatment and, occasionally, in merger control.

• A share transfer needs an instrument in writing, signed by transferor and transferee and certified by at least one witness under section 1129 of the Civil and Commercial Code. It is not filed with the Ministry of Commerce; the register of shareholders is what binds the company.
• Stamp duty is 0.1% of the value of the shares transferred, normally payable by the transferor. Thailand has no separate capital gains tax regime, so gains fall into ordinary income tax, and a foreign seller's position depends on the applicable double tax treaty.
• Securities and Exchange Commission rules bite only if the target is listed. A mandatory tender offer is triggered at 25%, 50% or 75% of voting rights, acquired directly, indirectly through the chain principle, or with concert parties. A private Co., Ltd. sits outside all of it.
• Merger control can still catch a mid-sized domestic deal. Under the Trade Competition Act B.E. 2560, a completed merger must be notified to the Trade Competition Commission within seven days where the parties' sales in the relevant market reach 1 billion baht, and pre-closing approval is required where the deal would create a monopoly or a dominant position.

A mid-market sale typically takes six to twelve months from mandate to close, with three to six months spent reaching a first serious offer. Preparation is the part owners want to compress and the part that decides the price: deals that reach exclusivity on thin preparation are the ones repriced when the buyer's accountants arrive.

What do M&A advisors in Thailand charge?

No fee survey exists for Thai mid-market advisory, so anyone quoting you a Thai benchmark is quoting a hunch. The nearest usable reference is the Firmex Global M&A Fee Guide 2024-25, published in April 2025 from a survey of 456 middle-market advisers across 49 countries run in December 2024 and January 2025. Half the respondents were North American and 44% European, so read the numbers as the shape of a fee curve, not a Bangkok price list.

Structure varies more than level. In that survey 41% of firms used a Lehman-style formula where the rate falls as the price rises (the classic version pays 5% on the first million, 4% on the second, down to 1% above five million), 27% charged a flat percentage, and 21% used an accelerator paying more above a threshold. The most common monthly work fee was $5,000 to $10,000, charged by 45% of firms, and more advisers than in 2023 agreed to credit those payments against the success fee. Only 4% of seller-focused firms charged no success fee at all.

Four questions decide what you actually pay:

1. Is the retainer credited against the success fee, or kept on top of it?
2. Is there a minimum fee? A $200,000 floor on a $3M sale is 6.7% however the percentage table is written.
3. What counts as transaction value? Debt assumed by the buyer, earnout instalments paid two years later, equity rolled into the buyer's holding company and property sold alongside the business can each sit inside or outside the definition, and the gap is often six figures.
4. How long is the tail? If a buyer the advisor introduced comes back fourteen months after the mandate expires, who is owed what?

Nobridge works on a success-fee basis, with the bulk of the fee payable only when a transaction closes. Whether that arithmetic works in a seller's favour is argued through in our look at whether mid-market M&A advisers earn their fees.

How do you judge a Thai advisor before you sign?

A private share sale of a Thai Co., Ltd. sits outside the SEC's remit, which polices takeovers of listed companies. No regulator vets the person you are about to hand your management accounts to, and there is no public league table for private Thai deals below $50M, so a track record cannot be checked against a database. You verify it yourself, in the meeting, with questions that have checkable answers.

1. Ask for the buyer list by type and country before you sign anything. Not the count, the composition. A properly run process engages 50 to 150 potential buyers to produce five to ten serious bidders, and an advisor who cannot say where those names would come from in your sector does not have them.
2. Ask who else they represent in your sector right now. An advisor running two competing mandates in Thai cold-chain logistics has a conflict, and the honest ones say so before you ask twice.
3. Ask how confidentiality is handled: anonymous teaser first, full information memorandum only after an NDA, one named person deciding who sees what. Informal outreach is how staff and customers find out.
4. Ask for two references from deals that closed in the last twenty-four months, and call them. Ask what went wrong, not what went well.
5. Ask who does the work. The partner who pitches is often not the person writing the memorandum or sitting in the diligence calls.
6. Ask what happens if you sell to a buyer you already knew. Carve-outs for pre-existing relationships are negotiable in the engagement letter and impossible afterwards.

What should you do, given where you are?

If you are two years out, the work has nothing to do with advisors. Normalise the financials, resolve any nominee shareholding left in the register by an earlier structure, and cut the number of customer relationships that run through you personally. Value enhancement programmes typically lift exit valuations 20-40%, and they need six to eighteen months to show up in the numbers.

If you are six months out, the question is process: a defensible valuation, a complete data room, a written view on whether your activity sits in List 3 and whether BOI promotion is available, and enough credible buyers that price is discovered rather than dictated. If a buyer has already approached you unsolicited, find out what else the market would pay before you grant exclusivity. An uncontested buyer has already done the arithmetic on an uncontested price.

If you want to know what your business looks like to a Japanese strategic, a regional private equity fund or a Thai conglomerate, and what a sale would realistically involve, you can start a confidential, no-obligation conversation about what your business looks like to a buyer.

Frequently Asked Questions

Can a foreigner own 100% of a Thai company?

Yes, in three situations. If the business is not on any of the three lists attached to the Foreign Business Act B.E. 2542, which includes most manufacturing, foreign ownership is unrestricted. If the buyer is American, the 1966 Treaty of Amity permits 100% ownership outside a defined set of carve-outs including transport, communications, banking with depository functions and land. And if the project receives BOI promotion, the promoted company can apply for a Foreign Business Certificate under Section 12, which lifts the shareholding restriction for the promoted activity.

Do I need a Thai M&A advisor, or can I use a foreign one?

There is no licensing requirement for advising on a private Thai share sale, so either can act. What matters is whether the advisor can run a confidential process in Thai and English, brief Thai counsel on the Foreign Business Act position, and reach the buyers who would actually pay, which for Thai manufacturing often means Japanese, Korean and Chinese strategics rather than local ones.

How long does selling a Thai mid-market business take?

Six to twelve months from mandate to close is normal, with three to six months to a first serious offer. Regulatory steps add time where they apply: a Foreign Business Licence application or a BOI submission for the buyer, and a pre-merger filing with the Trade Competition Commission if the combined business would be dominant in its market.

Does a share sale of a Thai company trigger tax for the seller?

Stamp duty of 0.1% of the value of the shares transferred applies to the transfer instrument. Thailand has no separate capital gains tax regime, so gains are taxed as ordinary income, and a foreign seller's position depends on the applicable double tax treaty. The answer turns on your own shareholding structure, so take Thai tax advice before agreeing a structure rather than after.
