Share

A public takeover is a regulated process where a company (the bidder) announces an offer to acquire the shares of a publicly traded target company. Success requires securing a majority of voting shares, and the process is strictly governed by codes like the UK's City Code on Takeovers and Mergers to ensure shareholder fairness. Unlike a private sale, bidders cannot rely on the same contractual protections, making the due diligence process and adherence to regulatory timetables critically important.
A public takeover occurs when one company makes a formal offer to purchase the shares of another company that is listed on a public stock exchange. The primary goal is to gain corporate control, typically defined as acquiring over 50% of the target's voting share capital. This process is fundamentally different from a private sale, where a company is sold in a negotiated transaction with a private buyer. The most defining feature of a public takeover is its regulation by official codes, such as the UK's City Code, which enforces principles like equal treatment for all shareholders. A takeover can be friendly (agreed upon by both companies) or hostile (opposed by the target's board).
The rules governing public takeovers create significant distinctions from private company sales. Based on the framework of the City Code, here are the key differences:
| Aspect | Public Takeover | Private Sale |
|---|---|---|
| Due Diligence | Often more limited; relies heavily on public information. | Typically extensive, with full access to the company's records. |
| Representations & Warranties | Generally not available to the bidder. | Standard part of the sale and purchase agreement. |
| Exclusivity & Break Fees | Generally prohibited by the City Code. | Commonly negotiated to lock in the deal. |
| Conditionality | Conditions cannot be based on the subjective judgment of the parties. | Can include a wide range of specific conditions. |
| Shareholder Treatment | Strict equal treatment for all shareholders of the same class. | Terms can be negotiated individually with major shareholders. |
Other critical differences include the requirement for a bidding company to have firm financing in place for any cash component before announcing an offer. Furthermore, a formal announcement commits the bidder to proceed and post detailed offer documents within a strict 28-day timetable.
There are two primary structures for executing a public takeover, each with its own procedural requirements and strategic implications.
Contractual Takeover Offer In a contractual offer, the bidder makes a direct offer to every shareholder of the target company. The bidder sends a detailed offer document and must secure acceptances for shares representing over 50% of the voting capital for the offer to become unconditional. To achieve 100% ownership and compulsorily acquire the shares of minority holders, the bidder typically needs to reach a 90% acceptance threshold. This structure offers more flexibility but requires a high level of shareholder approval for full control.
Scheme of Arrangement A scheme of arrangement is a court-approved agreement between the target company and its shareholders. It requires approval from a majority of shareholders in number, representing at least 75% of the shares voted. The main advantage is that once approved, the scheme is binding on all shareholders, which can provide more certainty of outcome. However, it is a less flexible process due to the involvement of the High Court and the need for detailed court filings.
In the UK, public takeovers are regulated by the City Code on Takeovers and Mergers. The Code is based on six General Principles that ensure a fair and orderly process. These principles are not merely guidelines but enforceable rules. The core principles mandate:
Based on our assessment experience, understanding these principles is crucial for any party involved in or affected by a public takeover bid.
Navigating a public takeover requires a clear understanding of its unique rules.
