Editor’s note: This is an educational explainer about how schemes of arrangement generally work as a UK take-private mechanism. It is general information, not investment advice, and does not describe any specific current event, company, or security.
A bidder can secure the backing of more than half of a UK-listed company’s shareholders and still fail to take it private, while another bidder with a structure requiring 75 percent approval can succeed with near-total certainty in a matter of weeks. The difference often comes down to a single procedural choice made at the outset: whether the deal is structured as a contractual takeover offer or as a scheme of arrangement. Understanding that choice explains much of how UK public-to-private transactions are actually engineered.
What a scheme of arrangement is
A scheme of arrangement is not, strictly speaking, a takeover mechanism at all. It is a court-sanctioned procedure under the UK Companies Act that allows a company to reorganize the rights of its members, in this case, by cancelling or transferring existing shares in exchange for cash or new securities, so that a bidder ends up owning the entire company. Because it operates through the courts rather than through direct contracts with individual shareholders, a scheme binds every shareholder once approved, including those who voted against it or did not vote at all.
That binding effect is the scheme’s defining feature. To be approved, a scheme needs the backing of a majority in number of shareholders present and voting at a special meeting, representing at least 75 percent of the value of shares voted, followed by sanction from the court, which checks that the process was fair and that shareholders were properly informed. Once the court sanctions the scheme and it is filed with the Registrar of Companies, it takes effect automatically for all shareholders on the register, and the target’s shares are cancelled or transferred in one stroke. There is no need to chase down the last few percent of holders individually, which is precisely what makes the mechanism attractive for a clean, complete take-private.
How a contractual offer works differently
The alternative route, a contractual takeover offer under the Takeover Code, works on an entirely different legal basis. The bidder makes a formal offer directly to each shareholder to buy their shares, and each shareholder decides individually whether to accept. The offer becomes unconditional once acceptances reach a stated threshold, commonly 90 percent of the shares to which the offer relates, at which point the bidder can invoke statutory “squeeze-out” powers to compulsorily acquire the remaining minority.
This is a fundamentally contractual process: shareholders who do not accept are not bound unless the 90 percent squeeze-out threshold is met, and reaching that figure can be far harder in practice than the scheme’s 75 percent-of-votes-cast test, particularly when share registers include passive funds, nominee accounts, or holders who simply never respond. A scheme’s 75 percent hurdle is also calculated only against shares actually voted, not the entire issued share capital, so in practice it can be cleared with support from a smaller absolute slice of the register than a 90 percent acceptance condition demands.
Why the choice matters for a deal
The practical trade-offs explain why bidders and boards weigh the two routes carefully. A scheme generally offers more certainty of achieving 100 percent ownership in a single, predictable step, and it usually cannot be effected without the target board’s cooperation, since the company itself must convene the shareholder meeting and apply to the court. That makes schemes the natural vehicle for recommended, board-backed transactions where speed and completeness matter, such as a private equity buyer wanting a clean delisting.
A contractual offer, by contrast, can be launched without board support, making it the only realistic route for a hostile approach, and it gives the bidder more flexibility to lower or waive the acceptance threshold if it decides a smaller stake is acceptable. It typically takes longer to reach finality if acceptances trickle in slowly, and reaching the 90 percent squeeze-out bar is not guaranteed even when a clear majority supports the deal. Both routes sit under the jurisdiction of the Panel on Takeovers and Mergers, which regulates timetables, disclosure, and shareholder treatment regardless of which structure is used, so the choice between them is a matter of mechanics and certainty rather than of regulatory oversight.
