Early-stage technology companies often need to raise capital quickly. For founders, the priority may be runway, product development, sales hiring, or closing a bridge round before the next equity financing. For investors, the priority may be speed, valuation protection, and a simple document that preserves the right to convert into shares later.
That is why convertible instruments are increasingly attractive in startup financing. They allow the parties to defer some valuation issues, provide downside protection through debt-style terms, and convert into equity if the company later raises a priced round.
However, in Thailand, founders and investors should exercise caution with terminology. A document referred to commercially as a “convertible note” should not be presumed to be a straightforward private loan that can subsequently be converted into shares solely by mutual agreement. When the instrument is intended to convert into equity, the involved parties must carefully consider Thailand’s securities regulations, company law, and the procedures for corporate approval from the outset.
This is particularly important as Thailand continues to position itself as a more supportive environment for startups, technology companies, and innovation-driven businesses. FOSR has discussed this policy direction separately in A New Era for Innovation: Understanding Thailand’s Draft Startup Promotion and Development Act.
The SEC Private-Placement Framework
Thailand’s Securities and Exchange Commission has established private placement channels to facilitate fundraising for small and medium-sized enterprises (SMEs), startups, and certain limited companies. The SEC stated that SMEs may issue shares or convertible debentures to a limited group of investors without submitting an application for approval or a registration statement to the SEC, provided the applicable conditions are met. The SEC also emphasized that the issuance of shares and convertible debentures constitutes a securities offering under the Securities and Exchange Act and remains subject to SEC regulations.
The relevant framework includes, among others:
- SEC Notification Kor.Jor. 3/2563, regarding exemption from filing a registration statement for convertible debentures issued by SMEs that are limited companies;
- Capital Market Supervisory Board Notification Tor.Jor. 17/2563, regarding private-placement offerings of newly issued securities by SMEs;
- SEC Notification Kor.Jor. 32/2565, regarding exemption from filing a registration statement for convertible debentures issued by limited companies; and
- Capital Market Supervisory Board Notification Tor.Jor. 25/2565, regarding private-placement offerings of newly issued securities by limited companies.
These rules are important because they show that Thailand does recognize a regulated route for private-company fundraising through shares and convertible debentures. But the existence of that route does not mean that any short-form convertible note, loan agreement, or debt-to-equity promise will necessarily produce valid and enforceable equity conversion.
For further background, see the SEC’s summary of private-placement offerings by SMEs and large enterprises.
Convertible Debenture, Not Merely “Convertible Note”
In international startup practice, the term “convertible note” is often used loosely. In Thailand, the more precise regulatory concept is generally the convertible debenture. The SEC describes a convertible debenture as an instrument that gives the investor the right to convert from creditor status into co-ownership of the business in the future.
That distinction matters. A convertible instrument may begin as debt, but if it is intended to convert into shares, the conversion requires a legally workable path. The company must be able to issue the shares, register the shareholder, comply with its articles of association, obtain required corporate approvals, and satisfy any applicable securities-offering conditions.
A founder may think, commercially, that the investor is “basically investing in equity.” But legally, the instrument may still be debt until conversion. The rights of a creditor, the rights of a shareholder, and the rights of a future shareholder are not the same.
For foreign founders and investors, these issues often arise alongside company establishment, foreign ownership, and corporate governance planning. FOSR’s Company Formation and Mergers & Acquisitions and Corporate Law practice pages discuss related corporate structuring issues in Thailand.
The “No Authorized but Unissued Shares” Trap
Foreign investors often assume that a Thai private limited company can simply issue shares later when conversion occurs. That assumption can be wrong.
Unlike some foreign corporate systems, a Thai private limited company typically does not maintain a pool of authorized but unissued shares that the board can issue later at its discretion. Issuing new shares normally requires an increase in registered capital, supported by the required shareholder approvals and corporate filings.
This is critical for convertible debentures. If the company has not properly addressed the underlying shares that will support conversion, the investor may have a contractual conversion right but no clear corporate path to receive validly issued shares. The issue should therefore be addressed when the convertible instrument is structured, not only when the investor later requests conversion.
This is one of the most common gaps in lean startup fundraising documents. The commercial term sheet may state “conversion,” but the company’s registered capital, shareholder approvals, pre-emption rights, articles of association, and Ministry of Commerce filings may not yet support the conversion mechanics.
The issue also connects with a broader point in Thai corporate practice: company registration and shareholding records are not merely administrative formalities. FOSR has discussed Thailand’s increased scrutiny of company registration and shareholder funding evidence in The End of the Filing Formality: Thailand’s New Front in Company Registration.
The Exemption Is Not a Free Pass
The SEC private-placement framework is designed to reduce unnecessary costs and burdens for qualifying companies while preserving investor-protection mechanisms. It is not a free-form exemption from securities regulation.
Depending on the issuer, investor category, and offering structure, the company may need to consider matters such as:
- whether the company qualifies under the relevant SEC route;
- whether the investor falls within a permitted investor category;
- whether the offering is genuinely private and not broadly advertised;
- whether a factsheet or other disclosure document is required;
- whether transfer restrictions must be registered for the convertible debentures;
- whether offering results must be reported to the SEC;
- whether conversion-exercise results must also be reported; and
- whether the company’s corporate approvals and share-issuance mechanics support the agreed conversion terms.
One practical point deserves emphasis. Under the PP rules, the issuer is generally required to report the results of the securities offering to the SEC within 15 days after the offering closes. For convertible debentures, the issuer must also report the results of the conversion exercise within 15 days after the conversion. This is a simple administrative step, but early-stage companies may overlook it.
The SEC’s materials also refer to fact sheet preparation, limited investor categories, transfer restrictions for convertible debentures, restrictions on broad advertising, and post-offering reporting obligations. See the SEC’s SME private-placement guidance.
Small Rounds Can Create Large Problems
In early-stage fundraising, the legal budget is often limited. This is understandable. A founder may be trying to close a small bridge round. An investor may not want legal fees to become disproportionate to the investment amount. Both sides may prefer to move quickly.
The risk is that a lean document may create problems later.
A defective or incomplete convertible instrument may not cause immediate difficulty when funds are transferred. The problem often appears later, when the company tries to close the next equity round, prepare a cap table, onboard a strategic investor, pass due diligence, raise foreign capital, restructure share rights, or complete an exit.
At that stage, the parties may need to answer uncomfortable questions:
- Was the original instrument properly characterized?
- Was the offering made under an available SEC exemption?
- Were the investors eligible?
- Were transfer restrictions and reporting requirements handled?
- Did the company have the authority to issue the conversion shares?
- Were pre-emption rights or shareholder approvals addressed?
- Was the registered capital increased in a manner that supports the conversion?
- Is the conversion formula enforceable and mechanically possible?
- Does the instrument conflict with the company’s articles or later financing documents?
If these issues were skipped at the beginning, they may become more expensive to correct later.
Investors Should Also Care
This is not only a company-side issue. Investors who want to operate lean should also care about Thai securities and company-law mechanics.
The investor’s commercial expectation may be simple: invest now and convert later at an agreed-upon valuation cap or discount. But that expectation depends on the legal enforceability of the conversion right and the company’s ability to issue valid shares. If the instrument is poorly structured, the investor may hold a repayment claim but not the equity position originally expected.
For foreign investors, these issues may also intersect with foreign ownership restrictions, nominee-shareholding concerns, and the Foreign Business Act. FOSR has discussed related foreign-investment issues in Thailand Proposes Landmark Reforms to Foreign Business Act to Attract Investment and Navigating Foreign Participation Regulations for Thai Companies.
For investors in Thai technology startups, the question is not only whether the business is promising. It is also whether the investment instrument actually gives the investor the rights it is supposed to provide.
Practical Takeaway
Convertible instruments can be useful for Thai technology startups. They may be appropriate for bridge financing, pre-seed rounds, and situations where valuation is difficult to settle immediately.
But they should be structured deliberately. Founders and investors should not assume that a foreign convertible note template can simply be copied into a Thai private-company context. Nor should they assume that a private loan agreement can automatically become equity without addressing the SEC, corporate, and share-issuance mechanics.
For small rounds, the better approach may sometimes be to simplify the deal rather than force a sophisticated instrument into a transaction that does not justify the legal and regulatory work. But where the parties do want true conversion rights, those rights should be built on the correct Thai legal foundation from the beginning.
For technology companies, this analysis should also sit within the broader legal environment for TMT, AI, data, and digital businesses in Thailand. FOSR’s Telecommunications, Media and Technology practice and article on Artificial Intelligence, Machine Learning, and Big Data in Thailand provide further context on the regulatory environment for technology businesses.
Convertible Debentures are Still Securities
Thailand’s SEC framework gives SMEs, startups, and limited companies useful private-placement routes for fundraising through shares and convertible debentures. That is a positive development for technology companies and startup investors.
The caution is equally important: private placement is still a regulated securities route, and a convertible debenture is not merely equity by another name.
For Thai tech startups and their investors, speed matters. But in convertible financing, legal mechanics matter too. Skipping those mechanics may save time at closing, but it can create larger problems when the company reaches its next financing round.
