Chapter 16: Foreign Investment Structures and the Ownership Question

16.1 Why This Chapter Exists

Every investor who reaches this report asks two questions in sequence. The first, how big is the market, is answered elsewhere. The second is the one most market reports never address: can I, as a foreigner, actually own and operate in it, and if not by ownership, then how? The answer determines whether capital enters legally or enters into a structure that is a criminal liability from the day it is signed. This chapter exists because that second question has a precise, knowable answer, and because getting it wrong is the most expensive mistake available in this market, more expensive than mispricing the opportunity, because it is not a loss of return, it is a loss of the whole investment plus criminal exposure.

The short version, established across this chapter: the licensed, plant touching core of Thai cannabis (cultivation, dispensary sale of the plant, extract production) cannot be foreign owned. Foreign capital participates through a Thai majority structure, through non equity instruments that carry no ownership cap, or, for Americans and for ancillary activities only, through the Treaty of Amity. The single largest source of loss in the market is not a bad structure that underperforms; it is a structure that is unlawful in substance and is now being actively prosecuted.

16.2 How Thailand Defines "Foreign", the Hinge

Everything downstream depends on one definition. Under Section 4 of the Foreign Business Act, a company incorporated in Thailand is treated as foreign primarily on a share count test: if non Thai persons hold 50% or more of the shares, the company is foreign [C]. The characterization rests on share ownership, not on who manages the company day to day. A foreigner may serve as managing director and the company remains Thai for FBA purposes as long as the 51% Thai shareholding holds [C]. This is the fact that makes a Thai majority joint venture the standard entry vehicle, and it is why the nationality of directors is not, by itself, the test.

There is a second, less applied limb worth respecting. The Section 4 definition also reaches a juristic person in which foreign persons contribute half or more of the total capital [L]. In practice the Department of Business Development applies the share count test as the primary filter, but the capital value limb means that a structure engineered so the foreigner holds only 49% of shares while contributing the overwhelming majority of the capital can draw scrutiny on the capital flow side even where the share ratio appears compliant. The lesson is that share count is necessary but not always sufficient; substance can be tested.

16.3 What Foreign Capital Can and Cannot Own

Dispensary retail and cultivation. These require a Thai majority company, foreign ownership capped at 49%, Thai ownership at 51% or more, and the licence is held by that Thai majority entity [C]. A foreigner cannot personally hold a cannabis licence; participation is through the company [C].

Extract production, a stricter bar. The April 2026 extract regulation does not merely cap foreign ownership; it excludes foreign businesses from the extract production licence entirely. The applicant must be a juristic person that is not a foreigner under the Foreign Business Act, a state agency, or the Thai Red Cross [C]. This is a hard exclusion, not a 49% ceiling, and it means the share class techniques that tilt economics within a 49% stake (below) do not open the extract licence to a foreign controlled entity. Foreign capital reaches the extract layer only around a genuinely Thai controlled licensee, never on the licence.

Directors. For FBA status, director nationality is not determinative [C]. Any cannabis licence specific requirement on director nationality or composition is a licensing form detail that should be confirmed against the current application at the time of filing rather than assumed [L]; this report does not assert a fixed director nationality rule for cannabis licences.

16.4 The Legitimate Structuring Toolkit

Within the ownership cap, real and lawful tools exist to align economics and protect a foreign investor, provided the Thai majority is genuine.

Preference shares and enhanced economics. Thai company law permits multiple share classes with different rights, set out in the Articles of Association filed with the Ministry of Commerce [C]. A foreign investor holding 49% can lawfully take enhanced economics, a preferential or priority dividend, priority on liquidation, through a preference class, provided the Thai shareholders are genuine, aware of the arrangement, and retain real rights [C]. Tilting the economics toward the foreigner on a genuine 49% is legitimate. Stripping the Thai majority of substantially all votes and dividends to manufacture disguised control is not, and is addressed in 16.6.

Non equity participation, no ownership cap applies. The 49/51 rule limits ownership of the company; it does not limit what the company may owe or pay. Foreign capital can therefore participate at scale without touching the ownership limit through instruments that carry no cap [L]:

• Offtake and forward purchase contracts.
• Toll manufacturing and contract processing arrangements.
• Brand, genetics, and technology licensing for a royalty.
• Equipment ownership and lease finance.
• Management and services agreements.

Each moves capital and value into the business while the licence stays in Thai hands. The one caution is that an instrument functioning as disguised control, a loan whose terms hand the foreigner the decision rights of an owner, can be re-characterized as a nominee arrangement; genuine commercial terms are the requirement.

The 49/51 requirement as a participation multiplier. The ownership rule is not only a constraint. Because every foreign entry mandates a Thai majority co-investor, foreign capital mobilizes Thai capital and Thai operators alongside it rather than entering alone, and the resulting Thai majority ownership builds a domestic economic constituency with a direct stake in the market's survival, one structural reason the recriminalization tail is rated Low (see Chapter 22). The constraint on foreign control and the market's political durability are the same mechanism.

16.5 The US Treaty of Amity: The American Only Question

American investors have one route no other nationality holds, and it is widely misunderstood in exactly the way that causes losses. Under the 1966 Treaty of Amity, US citizens and US majority owned companies may hold up to 100% of a Thai company and receive national treatment, exempt from most Foreign Business Act restrictions [C]. On its face this appears to place cannabis within reach for Americans. It does not, for two independent reasons, either of which is sufficient on its own.

First, the Treaty's own carve-outs. Amity contains a fixed set of excluded sectors: communications, transportation, fiduciary and banking functions, land ownership, exploitation of land and natural resources, and domestic trade in indigenous agricultural products [C]. Cannabis cultivation is agriculture and land use; the cannabis flower is a controlled herb, an indigenous agricultural product; domestic trade in the plant and its cultivation sit inside the excluded categories. The Treaty does not reach them.

Second, and decisive on its own, sector specific statutes are not overridden. The Treaty relieves the Foreign Business Act; it does not displace the cannabis and narcotics statutes, which carry their own nationality requirement [C]. The extract regulation requires the licensee to be not a foreigner under the Foreign Business Act. An Amity company remains a foreigner in ownership terms. It is US majority owned; the Treaty grants it an exemption to operate despite being foreign, it does not convert it into a Thai juristic person. A statute that demands a non foreigner is therefore not satisfied by an Amity company, and the cannabis regime grants no Amity waiver [L]. The reasoning is the report's own and merits Thai counsel's confirmation, but the statutory logic is clean.

Where Amity genuinely helps: the ancillary layer. A US investor can own up to 100% of a cannabis adjacent services, technology, logistics, or consulting business under Amity, where that activity is neither the excluded agriculture and plant trade nor a plant touching licensed activity [L]. That is a real, US only edge. It simply does not reach the grow, the dispensary's plant sales, or the extractor.

16.6 The Nominee Trap: How Investors Lose Everything

This section is the one an investor cannot get from a market size report, and it is where the largest losses in this market are made. It describes a structure that is widely offered to foreign entrants and that is, in its aggressive form, a criminal offence under active enforcement.

The structure as offered. The pattern is consistent [L]: the foreign investor is offered 49% of the shares but carrying the great majority of the voting rights and nearly all of the dividends; the Thai "majority" is a holding company or individual holding 51% through a preference class that carries almost no votes and almost no dividends, contributing little or no genuine capital; a Thai nominee director is installed temporarily and resigns once the foreigner's visa and work permit are secured; and the company is sometimes incorporated first entirely in names supplied for that purpose and transferred afterward. On paper it reads as foreign control with Thai majority compliance.

Why it is unlawful. The arrangement meets the definition of a nominee under Section 36 of the Foreign Business Act: a Thai holder who does not genuinely invest, holds no meaningful beneficial interest, and exercises no real control, standing in as a front to let a foreigner operate a restricted business [C]. Section 36 is criminal. Penalties run to imprisonment of up to three years and fines of 100,000 to 1,000,000 THB, applied to both the foreigner and the Thai party, together with dissolution of the company [C]. Where the foreigner's capital also constitutes the majority of total capital, the capital value limb of Section 4 compounds the exposure.

Why 2026 is not 2022. Structures of this kind were offered openly during the deregulated 2022 to 2023 window. The enforcement environment has since changed materially. Through 2024 to 2026 the Department of Business Development intensified scrutiny of shareholding structures, voting arrangements, and preference share allocations that disguise foreign control, and began cross checking company registrations against Revenue Department records to trace whether Thai shareholders actually funded their shares [C]. The structure that was tolerated is now specifically targeted.

The cannabis specific bite. For cannabis the exposure is worse than for a typical restricted business, for two reasons. First, stripping the Thai majority of votes and dividends makes the entity Thai on paper and foreign in substance, which fails the cannabis licensing requirement for a genuinely Thai entity, so the same structure that risks a nominee prosecution also jeopardizes the licence itself. Second, licensed cannabis operators are already under continuous regulatory surveillance, inspections, prescription records, monthly reporting, so a nominee structure inside a licensed dispensary or extractor is far more visible than the same structure in a dormant holding company.

The red flag audit. An investor can hold any proposed structure against this checklist. Any one of these is a signal that the structure on offer is the nominee version [L]:

1. The Thai "partner" contributes no capital and shares no risk.
2. Preference shares are used to reduce the Thai majority to near zero votes and near zero dividends.
3. A Thai nominee director is installed on the understanding that they resign later.
4. The company is proposed to be started entirely in names supplied for that purpose and transferred afterward.
5. The arrangement's economics and control are documented in a side agreement kept off the public filings.
6. The structure is pitched as "100% control" or "you own it in everything but name."

16.7 The Legitimate Alternative: The Fork in the Road

The same investor, the same capital, and the same ambition can be structured lawfully. The defensible route has three components, used together or singly:

1. A genuine Thai principal on the 49/51, who invests real capital, holds real votes, and shares real risk, with the foreign investor taking enhanced economics through a properly drafted preference class rather than stripping the Thai of everything [L].
2. Non equity instruments, offtake, toll manufacturing, brand and technology licensing, equipment and lease finance, management contracts, to place the majority of capital and returns without exceeding the ownership cap [L].
3. Amity for the ancillary layer (US investors only), and extract participation through a Thai controlled licensee rather than on the licence [L].

The scarce input in the lawful version is not capital; it is a credible, adequately capitalized Thai partner. Partner due diligence, not structure engineering, is the determinant of a compliant entry. In a consolidating, oversupplied market, the genuine Thai principal is the genuine bottleneck.

16.8 Investment Read

Ownership of the licensed core is capped; participation is not. The market is investable to foreign capital, but the structure chosen is itself the primary risk, more so than the market risks catalogued elsewhere, because it is binary and criminal rather than a matter of return. The aggressive nominee structure still on offer is the single most expensive error available in this market, and it is now under active enforcement; the lawful alternatives are slower, require a genuine Thai principal, and survive due diligence. The variable that could relax the ownership ceiling is the Cannabis and Hemp Act, which would move the foreign ownership question from ministerial adjustability to statutory definition; until it passes, 49% is the ceiling and the extract licence is closed to foreigners outright. An investor who internalizes this chapter finishes able to audit their own term sheet, which is the difference between entering this market and being sold into it.
