Form 246-2 is Thailand's substantial-shareholding report, filed with SEC Thailand under the Securities and Exchange Act B.E. 2535 and triggered when a holding crosses 5% of voting shares and each further 5%. Because a properly structured pledge does not change the borrower's registered holding, granting it is generally distinct from the acquisition or disposal events that drive a filing.
For anyone with a meaningful stake in a Thai-listed company, one question sits behind almost every financing decision: will this show up publicly? Thailand runs a disclosure regime — built around a well-known 5% threshold and the report called Form 246-2 — that makes substantial shareholdings, and significant moves in them, visible to the market and to the regulator. When you are thinking about raising cash against your shares through a stock loan, it is natural to ask how pledging shares interacts with that regime. This note explains what Form 246-2 is, how the 5% multiples work, and — the part that matters most for a borrower — how a properly structured pledge sits alongside the reporting rules. It is educational only; the reporting analysis for any real situation belongs to your own Thai counsel.
Key takeaways
- Form 246-2 is Thailand's substantial-shareholding report, filed with SEC Thailand under the Securities and Exchange Act B.E. 2535.
- It is generally triggered when a holding crosses 5% of a company's voting shares, and each further multiple of 5% — both up and down.
- A stock loan we arrange does not sell or transfer your shares; they stay in your own account, so granting the pledge is generally distinct from an acquisition or disposal.
- Where reporting does bite — for example, on enforcement — the analysis is worked out in advance with counsel, and conservative structuring keeps forced sale remote.
- The filing obligation rests with the holder, not with us; we structure for a clean disclosure profile, we do not file or advise on the law.
What Form 246-2 is
Thailand's securities markets operate under the Securities and Exchange Act B.E. 2535 (1992), administered by the Securities and Exchange Commission (SEC Thailand). Among the Act's investor-protection tools is a duty on substantial shareholders to disclose their holdings. The vehicle for that disclosure is Form 246-2 — the report that tells the SEC, and through it the market, that a person has reached or moved through a significant level of ownership in a listed company.
The purpose is transparency. A market functions better when large stakes cannot be assembled or unwound in the dark: other shareholders, potential bidders, and the regulator can all see when ownership shifts at scale. Form 246-2 is how Thailand delivers that visibility. It is a reporting obligation, not a permission — it does not ask the SEC to approve anything, it simply records that a threshold has been crossed.
How the 5% multiples work
The mechanism is deliberately simple, which is part of its strength. Disclosure is keyed to bands of 5% of a company's voting shares. A report is generally required when a person's holding first reaches 5%, and then again each time it passes a further multiple — 10%, 15%, 20%, and upward. Crucially, the duty runs in both directions: reducing a stake through a 5% multiple is reportable just as building one is. Someone quietly trimming a large position is as visible, at each step, as someone accumulating.
- Reaching 5% of a company's voting shares — the first report.
- Each further multiple — 10%, 15%, 20%, and upward.
- In both directions — building a stake and reducing one are each reportable at every 5% step.
Two points are worth holding in mind. First, the count is of voting shares, which is why the form a holding takes — ordinary shares versus depositary receipts — can matter to the analysis. Second, the 5% regime is separate from the higher tender-offer thresholds of 25%, 50%, and 75%, which can trigger a mandatory offer under Thailand's takeover rules. A single transaction can potentially touch both regimes, which is exactly why the analysis is left to counsel rather than reduced to a rule of thumb.
| Regime | Trigger | Nature |
|---|---|---|
| Form 246-2 (5% reporting) | Crossing 5% and each further multiple of 5%, up or down | Disclosure of a substantial shareholding to SEC Thailand |
| Tender-offer thresholds | Crossing 25%, 50%, or 75% of voting rights | Can trigger a mandatory tender offer under takeover rules |
How a pledge interacts with the regime
Here is the question a borrower actually cares about: if I pledge my shares to secure a stock loan, does that pledge have to be disclosed on Form 246-2? The honest answer is that it depends on the facts and is a matter for Thai counsel — but the structure we use is designed with this question front of mind, and understanding why is genuinely reassuring.
In the structures we arrange, taking a stock loan does not sell your shares and does not transfer them into the lender's name. They remain in your own account at a designated custodian, held in book-entry form at the Thailand Securities Depository (TSD), and the lender's security arises from its rights and control over that account rather than from any change of ownership. We explain that mechanism in detail in our note on TSD custody and perfecting a share pledge. Because your registered holding does not change when the pledge is granted, granting a pledge is generally distinct from the acquisition and disposal events that drive Form 246-2 reporting.
The 5% regime tracks who owns the voting shares. A well-structured stock loan does not change who owns them — it records a lender's security over an account you continue to hold. That distinction is the whole reason a pledge and a disclosure are not the same event.
That said, "generally distinct" is not "never relevant". Whether any given arrangement engages a reporting obligation depends on your status, the size of the position, its form, and the precise terms — and it is not something we determine. What we do is structure the transaction so that its disclosure profile is understood before anyone signs, and make sure your Thai counsel has the documents and the facts they need to advise.
Where reporting can genuinely bite: enforcement
There is one scenario where the 5% regime clearly comes into view, and it is worth naming plainly: enforcement on a default. If a lender ever had to realise the collateral by selling pledged shares, that is a genuine acquisition-and-disposal event. Your own holding would fall and could cross a 5% multiple downward — potentially reportable — and a party acquiring a large block could have reporting of its own. This is precisely the outcome a sound structure is built to avoid.
It is one of the clearest reasons a stock loan should be sized conservatively from the outset. A sensible starting loan-to-value, a documented recourse profile, and a margin mechanism that gives room to respond are all designed to make forced sale a remote event rather than a live risk. And where any disclosure would follow an enforcement, it is far better to have mapped it with counsel in advance than to meet it as a surprise.
Whose duty is it?
The reporting obligation under Form 246-2 rests with the person whose holding crosses the threshold — the shareholder — not with an arranger. We do not file on your behalf, and we do not give legal or regulatory advice. Our role is narrower and specific: to arrange and structure the financing, to make the disclosure implications visible at the outset, and to work alongside the licensed Thai counterparties, custodians, and counsel who each carry their own responsibilities. Your Thai counsel, engaged in parallel during documentation, is the party who confirms whether a filing is required, drafts it if so, and meets the deadline.
NVDRs, the foreign board, and the count
Because the 246-2 regime is built around voting shares, the form your holding takes affects the analysis. Ordinary shares on the local board or the foreign board carry votes; an NVDR passes through the economic rights of a share — price and dividends — but not the vote at company level. How each is counted for substantial-shareholding purposes is a technical question that turns on the specifics of your position. If your exposure sits in NVDRs or on the foreign board, the reporting treatment is one more thing to confirm with counsel; our note on foreign limits and NVDRs explains how those forms behave as collateral more broadly.
| Form of holding | Carries a vote? | How it counts for Form 246-2 |
|---|---|---|
| Ordinary shares — local board | Yes | Within the voting-share count the 246-2 regime is built around |
| Ordinary shares — foreign board | Yes | Voting shares; foreign-board treatment is one more thing to confirm with counsel |
| NVDR | No | Passes economic rights but not the vote; a technical question that turns on the specifics — confirm with counsel |
How this fits the wider transaction
Disclosure sits quietly across our whole process, from the first confidential enquiry through documentation to funding. It informs how a position is sized, how the collateral is held, and what your counsel is asked to sign off. The glossary defines the terms used here, and the regime itself is administered by the Securities and Exchange Commission of Thailand under the Securities and Exchange Act B.E. 2535. None of this replaces advice: it is the map, not the territory.
