Compulsory Acquisition of Minority Shareholders (SGX) Singapore: The 90% Squeeze-Out Rule
How Section 215 of the Companies Act lets an offeror force out shareholders who reject a takeover
Compulsory acquisition is a statutory right under Section 215 of Singapore’s Companies Act 1967 that allows an offeror who has acquired at least 90% of a target company’s shares through a general takeover offer to force the remaining dissenting shareholders to sell their shares at the same offer price, effectively completing a full buyout without unanimous consent.

- The compulsory acquisition — or ‘squeeze-out’ — right under Section 215 activates once an offeror holds at least 90% of shares in the target, excluding shares the offeror already owned before the offer.
- A 2023 amendment expanded the list of shareholders excluded from the 90% calculation to include concert parties, close relatives, and persons accustomed to acting on the acquirer’s instructions, making the threshold harder to reach artificially.
- Dissenting shareholders whose shares are compulsorily acquired can apply to the court within one month to object to the terms, though successful court challenges are rare.
- This mechanism is distinct from a voluntary delisting exit offer — it is triggered automatically once the 90% threshold is met within a general takeover offer, not by a separate shareholder vote.
- The offeror must exercise the squeeze-out right within two months of reaching the 90% threshold, and generally within four months of the original offer being made.

What Is Compulsory Acquisition?
When a company is taken over in Singapore, the offeror rarely starts out owning 100% of the target. A general takeover offer is made to all shareholders, and acceptances trickle in over the offer period. If enough shareholders accept — specifically, once the offeror’s total holding (original stake plus new acceptances) reaches 90% of the shares to which the offer relates — the law gives the offeror a statutory right to compulsorily acquire the shares of shareholders who did not accept, at the same price offered to everyone else. This is commonly called the “squeeze-out” right, and it exists precisely to prevent a small residual group of holdout shareholders from indefinitely blocking a company from becoming a fully-owned private subsidiary after an overwhelming majority has already agreed to sell.
The rule sits in Section 215 of the Companies Act 1967 and works alongside, but separately from, the SGX Take-over Code that governs how the offer itself must be conducted. Without this mechanism, an offeror could reach 99% ownership and still be stuck running the company as a listed or quasi-listed entity indefinitely because of a handful of shareholders holding out, which would undermine the practical purpose of most takeovers — full operational and capital control.
How It Works in Singapore
Historically, calculating the 90% threshold simply meant looking at total acceptances against total shares (excluding the offeror’s own pre-offer stake). On 9 May 2023, Parliament passed amendments — effective 1 July 2023 — that expanded the categories of shareholders excluded from that calculation, closing a loophole where an offeror could artificially inflate its “acceptance” percentage using related or connected parties who were never genuinely independent sellers.
| Excluded From 90% Calculation (Post-1 July 2023) |
|---|
| The offeror itself and its related corporations (parent, subsidiaries, fellow subsidiaries) |
| Their respective nominees |
| Persons accustomed or obligated (formally or informally) to act on the offeror’s directions or instructions |
| The offeror’s close relatives: spouse, parents, siblings, children (including adopted and step-children) |

Once the 90% threshold (calculated under the tightened rules) is genuinely met, the offeror has a defined window — generally within two months of reaching 90%, and the overall offer process typically must conclude within four months of the initial offer — to send a formal notice to the remaining dissenting shareholders exercising the compulsory acquisition right. Those shareholders are then bought out at the same price as the original offer; there is no separate negotiation. A dissenting shareholder who believes the terms are unfair can apply to the Singapore courts within one month of receiving the notice to object, though Singapore courts have historically been reluctant to overturn a price that has already been accepted by 90% of independent shareholders, absent clear evidence of unfairness or bad faith.
Worked Example
It is worth distinguishing compulsory acquisition from a scheme of arrangement, another mechanism sometimes used to take a Singapore company private. A scheme of arrangement requires court sanction and a different voting threshold, a majority in number representing at least 75% in value of those voting, and can bind all shareholders, including those who voted against it, once approved, without needing to first cross the 90% acceptance threshold that a general offer-based squeeze-out requires. Offerors sometimes choose between a general offer with compulsory acquisition and a scheme of arrangement based on which structure better suits the target’s shareholder base and the certainty of outcome they need.
An offeror already holds 60% of a target company and launches a general takeover offer at S$1.20 per share. Over the offer period, independent shareholders holding a further 33% of shares accept, taking the offeror’s total genuine holding to 93% (with the 2023 rules ensuring none of that 33% includes disguised related-party acceptances). Because this exceeds the 90% threshold, the offeror can issue compulsory acquisition notices to the remaining 7% of dissenting shareholders, buying them out at the same S$1.20 per share within the statutory window. A shareholder who believed S$1.20 undervalued the company could apply to the court within one month, but would need to show the terms were unfair — a high bar given that an overwhelming majority of independent shareholders already accepted the same price voluntarily.
Advantages
- Enables clean, complete takeovers. Once an overwhelming majority has agreed to sell, the squeeze-out right prevents a small residual group from indefinitely blocking full private ownership.
- 2023 amendments strengthened minority protection. Excluding concert parties and close relatives from the 90% calculation makes it materially harder for an offeror to reach the threshold through anything other than genuine, independent acceptances.
- Guaranteed same price as the majority. Squeezed-out shareholders receive exactly the same offer price as everyone who accepted voluntarily — there is no separate, lower ‘forced sale’ price.
- Court oversight remains available. Dissenting shareholders retain a formal, time-bound right to challenge the terms in court, even though the bar for a successful challenge is high.
Risks and Limitations
- You can be forced to sell even if you disagree. Once the genuine 90% threshold is met, dissenting shareholders lose the practical ability to simply hold their shares indefinitely — this is a real loss of optionality for minority investors who wanted to stay invested.
- Court challenges rarely succeed. Singapore courts give significant weight to the fact that 90% of independent shareholders already accepted the same price, making it difficult to prove the terms were unfair.
- Tight statutory deadlines. A shareholder who wants to object must act within one month of the compulsory acquisition notice — missing this window forecloses the challenge entirely.
- Threshold calculation complexity. The 2023 exclusion rules, while protective, also add complexity to verifying whether a stated 90% acceptance is genuinely calculated correctly, which is difficult for an individual retail shareholder to independently audit.
Compulsory Acquisition vs Voluntary Delisting Exit Offer
| Feature | Compulsory Acquisition | Voluntary Delisting Exit Offer |
|---|---|---|
| Legal basis | Companies Act 1967, Section 215 | SGX Listing Rules on voluntary delisting |
| Trigger | 90% acceptance threshold reached in a general takeover offer | Company applies to delist; requires shareholder vote |
| Shareholder vote required | No — automatic right once threshold is met | Yes — special resolution, ≥75% for / ≤10% against |
| Price offered to holdouts | Same as the general offer price, no separate negotiation | The exit offer price, opined on for fairness and reasonableness by an IFA |
| Challenge mechanism | Court application within 1 month of notice | Vote against the delisting resolution, or raise concerns via the IFA process |
The Bottom Line
Compulsory acquisition under Section 215 is the mechanism that lets a takeover reach a clean, complete conclusion once an overwhelming majority of shareholders have already agreed to sell — and the 2023 tightening of the 90% calculation gives Singapore minority shareholders meaningfully better protection against artificially manufactured thresholds. It is not, however, a mechanism minority shareholders can simply opt out of once the genuine threshold is met.

Frequently Asked Questions
What is the compulsory acquisition threshold in Singapore?
Under Section 215 of the Companies Act, an offeror can compulsorily acquire the shares of dissenting shareholders once it holds at least 90% of the target company’s shares (excluding shares it held before the offer and certain related parties), acquired through a general takeover offer.
What changed in the 2023 amendment to compulsory acquisition rules?
Effective 1 July 2023, the categories of shareholders excluded from the 90% calculation were expanded to include the offeror’s related corporations and their nominees, persons accustomed to acting on the offeror’s instructions, and the offeror’s close relatives — making it harder to reach the threshold through non-independent acceptances.
Can I refuse to sell my shares if the offeror reaches 90%?
No, not practically. Once the offeror genuinely reaches the 90% threshold, it has a statutory right to compulsorily acquire your shares at the same offer price. You can apply to the court within one month to challenge the terms, but such challenges rarely succeed.
How is compulsory acquisition different from a voluntary delisting exit offer?
Compulsory acquisition is an automatic statutory right triggered when an offeror crosses the 90% acceptance threshold in a takeover offer, with no separate shareholder vote required. A voluntary delisting requires the company to hold a shareholder vote and make a separate exit offer that an Independent Financial Adviser must opine is fair and reasonable.
How long does an offeror have to exercise the compulsory acquisition right?
An offeror generally must exercise the squeeze-out right within two months of reaching the 90% threshold, within an overall takeover process that typically must conclude within four months of the original offer being made.
