Yes, in some circumstances. If a company you hold shares in is taken over and the bidder gains enough control, it can start a compulsory acquisition, and you can be required to sell even if you did not accept the offer1. This is often called a squeeze-out. It applies to the shareholders who held out while most others accepted.
Yes, in some circumstances. If a company you hold shares in is taken over and the bidder gains enough control, it can start a compulsory acquisition, and you can be required to sell even if you did not accept the offer1. This is often called a squeeze-out. It applies to the shareholders who held out while most others accepted.
The mechanism exists so that a buyer who has won almost total control is not left with a handful of minority holders it cannot deal with. The trade-off for you is that the decision to sell is no longer entirely yours. What the rules do give you is a price built on the same offer other shareholders accepted, a short window to challenge the terms in court, and, in the reverse situation, a right to make the buyer take your shares.
This page explains what compulsory acquisition is, what triggers it, what you are paid and when, how to challenge it, and what happens when your shares sit inside an ISA or are held through a platform.
What compulsory acquisition means for shareholders
A compulsory acquisition is the point at which your holding stops being a stake you choose to keep and becomes a stake you are required to give up. The buyer is not asking again; it is using a right that follows from the level of control it has reached. The practical effect is that the shares leave your account and money arrives in their place, whether or not you replied to the offer.
It helps to separate two things that often get muddled. The first is the takeover offer itself, which you can accept or decline. The second is what happens afterwards if enough other shareholders accept. A bidder that gains enough control may start a compulsory acquisition, and in that case you could be required to sell even if you do not accept1. Declining the offer does not, by itself, preserve your holding.
Corporate actions generally fall into two kinds. Mandatory actions are started by the company's board of directors, and shareholders do not have to act on them but are affected as beneficiaries2. A squeeze-out sits in that category: the machinery runs without your instruction. Voluntary actions, by contrast, need a decision from you, which is why a rights issue offers a menu of choices such as taking up the rights, selling them to another investor, taking up part of them, or taking no action at all2.
The scale of a takeover can also be shaped by competition rules rather than by shareholder votes. In the United States, for example, the authorities ban acquisitions that would result in a bank controlling more than 10 per cent of the country's insured deposits6. That is a limit on the buyer, not a protection for you, but it shows that the terms of a deal are not set by the offer document alone.
What triggers a squeeze-out after a takeover offer
The squeeze-out is triggered by the level of control the bidder reaches, not by the size of your own holding. Once a bidder has acquired enough of the company, it can require the remaining holders to sell on the same terms. The point of the threshold is to draw a line between a bidder that has won the argument and one that has not.
Because the trigger is a proportion, it is worth being clear about what a proportion means in practice. A 70 per cent stake and a 30 per cent stake are two halves of the same company, and the split between them is what decides who controls it7. A bidder needs to cross the threshold, not to persuade every last holder. That is why a small number of holdouts cannot block a deal once the level is reached.
The threshold also explains the timing. Offers are usually left open for a period, and the bidder counts acceptances as they come in. If the count reaches the level, the squeeze-out follows; if it does not, the offer may lapse and your shares stay yours. Nothing about the process requires you to have voted in favour, and nothing about it requires you to have replied at all.
For a private company the position is different, because there is no traded market and no takeover offer in the same sense. Private companies can issue a small amount of equity for public purchase without having to be on a stock exchange8, but the rights of a minority holder in a private company rest mainly on its articles and on any agreement between the owners. Where joint owners cannot agree a sale, the courts can order a sale3. That is a separate route from the squeeze-out rules, and it turns on the facts of the ownership rather than on a percentage of acceptances.
What you are paid and when the money arrives
The price in a compulsory acquisition is built on the terms of the offer that other shareholders accepted. The rules are designed so that a minority holder is not paid less than those who accepted early, which is the main financial protection the process gives you. If the offer included a choice between cash and shares, the notice will set out how that choice is treated for holders who did not elect.
Timing is less tidy than the price. The buyer has to complete the acquisition and then settle with the holders, and the money can arrive after the shares have already left your account. Where a shareholder cannot be traced, the amount owed is generally held rather than lost, and can be claimed later. Keeping your address and contact details up to date with your platform or registrar is the simplest way to make sure a payment reaches you.
It is worth knowing how payment mechanics work elsewhere, because the same principles recur. Where a court orders money to be paid over, the employer sends the money to the court rather than to the individual9. Where a public body makes a payment to a parent, it aims to pass it on within one week of receiving it10. The lesson for a squeeze-out is that the money moves through an intermediary, so the date you are told about is not always the date it lands.
Challenging a squeeze-out: six weeks to apply to court
If you think the terms are unfair, the route is an application to court, and the window is short. The figure usually quoted is six weeks from the notice. Miss it and the acquisition stands. The court is not there to re-run the argument about whether the takeover should have happened; it looks at whether the terms offered to the minority are fair.
Six weeks is a recurring kind of deadline in UK procedure, which is a useful benchmark for how tight it is. A tenant who can prove extreme hardship may have possession delayed for up to 6 weeks11. Where a landlord applied for possession because of serious rent arrears, the maximum time the court can give is six weeks12. In Northern Ireland, a buyer under the House Sales Scheme must make a decision about going ahead within six weeks of receiving the offer13. Deadlines of this length are meant to be workable, not generous.
If you are considering an application, the practical steps are to note the date on the notice, keep the offer document and any correspondence, and take advice early rather than at the end of the period. The court route is the only formal challenge to the price; there is no separate negotiation with the buyer once the right has been exercised.
Sell-out rights: making the buyer take your shares
The squeeze-out has a mirror image. Where a bidder has reached the threshold, a remaining holder can require the buyer to acquire their shares on the same terms. This is the sell-out right, and it matters because it gives you an exit at the offer price rather than leaving you locked into a company that is now almost entirely owned by someone else.
The logic is symmetrical. If the buyer can compel you to sell, you can compel the buyer to buy. Both run off the same offer terms, so the price is the same in either direction. For a holder who wants out, the sell-out right is the cleaner route, because it does not depend on the buyer choosing to exercise its own power.
The wider family of shareholder choices shows how unusual the compulsory route is. In a rights issue, a holder can take up the rights, sell them to another investor, take up part of them, or take no action2. Those are voluntary decisions with a menu of outcomes. A squeeze-out has no menu: the only variables are the price, which is set by the offer, and whether you challenge it in time.
Shares held on a platform, in an ISA or through a nominee
Most people do not hold share certificates. They hold investments through a platform, and the platform holds them through a nominee. Your investments are held in the name of the nominee company or another approved custodian, separate from the firm's own assets14. That separation matters if the firm fails, but during a squeeze-out it means the paperwork and the payment run through the platform rather than through you directly.
The tax position does not change because a nominee is involved. A forced sale is still a disposal, and Capital Gains Tax can apply to a profit on selling or disposing of assets such as shares4. Your cost basis depends on how you got the shares. If you acquired them by exercising an employee option, you are generally treated for capital gains purposes as acquiring them at the date you exercise the option15. If you received free or cheap shares outside an approved scheme and not by exercising an option, the cost is generally their market value at the date you acquire them15. Shares of the same class in the same company acquired on the same day are normally pooled15.
ISAs have their own rules. Only authorised or recognised funds may be held in a stocks and shares ISA under current law5, and certain investments subject to a notice period that cannot be held in a stocks and shares account may be held in an innovative finance account16. If your shares are inside a stocks and shares ISA, the squeeze-out still applies, but the platform handles the mechanics. If you are unhappy with how a firm handled it, the Financial Ombudsman Service can look at complaints about stocks and shares17.
Where the protection stops
The protections in a squeeze-out are real but narrow. You get the same price as accepting shareholders, a short window to challenge the terms in court, and, in the mirror case, a right to make the buyer take your shares. What you do not get is a veto. Once the threshold is crossed, the decision to sell has effectively been made by the other shareholders, and your holding goes with it.
The tax treatment is not softened by the fact that the sale was forced. A disposal is a disposal, and Capital Gains Tax can apply to a profit in the same way as a sale you chose to make4. That is why records matter: the date you acquired the shares, what you paid, and how you came by them all feed into the calculation, and reconstructing them years later is harder than keeping them.
If you need help understanding your position, free and impartial guidance is available. The Financial Ombudsman Service handles complaints about stocks and shares17, and it can look at how a firm dealt with a corporate action as well as the investment itself. For the tax side, the government's own guidance on employee share schemes and on Capital Gains Tax sets out the rules in plain terms4. Where a private company is involved and the ownership is disputed, the courts can order a sale3, and that is a matter for legal advice rather than for a complaints route.
