Planning for the future: What to include in a UK shareholders’ agreement

A well-drafted agreement sets clear ground rules for how the company is run, how decisions are made, and what happens when circumstances change.

UK shareholders’ agreement

A shareholders’ agreement is one of those documents that often feels unnecessary at the outset, when everyone involved is aligned and optimistic about the future. In practice, it can be one of the most important documents a company ever puts in place. A well-drafted agreement sets clear ground rules for how the company is run, how decisions are made, and what happens when circumstances change.

This article examines the key provisions typically included in a UK shareholders’ agreement and explains why they matter.

The role of a shareholders’ agreement

A shareholders’ agreement is a private contract between some or all of a company’s shareholders. It sits alongside the company’s Articles of Association and addresses matters that are often too detailed, too commercial, or too sensitive to include in the Articles. Its purpose is to provide clarity, manage expectations, and reduce the scope for disputes as the business grows or changes.

Company management and governance

Most agreements begin by addressing how the company is managed and how key decisions are made.

Decision-making provisions typically distinguish between matters the board can handle and those that require shareholder approval. Reserved matters often include issuing new shares, selling major assets, borrowing above agreed limits, or changing the nature of the business. It is common for these decisions to require a higher voting threshold, such as a supermajority, rather than a simple majority.

The agreement will also set out how directors are appointed and removed, whether particular shareholders are entitled to nominate a director, and how board seats are allocated. It will often cover director remuneration, service contracts, and decision-making at board level to ensure transparency and consistency.

Share ownership and transfer of shares

Rules governing share ownership and transfers are at the heart of most shareholders’ agreements.

Restrictions on transfers are used to prevent shares from being sold to third parties without the consent of the existing shareholders. Pre-emption rights are fundamental, giving existing shareholders the first opportunity to purchase shares offered for sale or newly issued, helping to prevent unwanted dilution or changes in control.

Drag-along and tag-along rights are also common. Drag-along provisions allow the majority shareholders to compel minority shareholders to sell their shares on the same terms as the company’s sale. Tag-along rights protect minority shareholders by enabling them to join a sale and exit on equivalent terms.

Leaver provisions address what happens when a shareholder leaves the business due to resignation, retirement, death, illness, or insolvency. These clauses often distinguish between good leavers and bad leavers, with different valuation outcomes depending on the circumstances. Closely linked to this are valuation mechanisms, which set out how shares will be valued in various scenarios, helping to avoid disputes at a difficult time.

Financial arrangements

Financial provisions help ensure that everyone understands how the company will be funded and how returns are distributed.

Funding clauses set out how additional capital will be raised, whether shareholders are obliged to contribute, and what happens if someone cannot or will not do so. Dividend policy provisions specify when profits may be distributed and whether profits are likely to be retained for growth.

In some companies, particularly those with external investment, liquidation preference clauses may be included. These clauses determine who is paid first and in what order if the company is sold or wound up.

Protecting shareholders

A shareholders’ agreement often includes specific protections for minority shareholders. These may include veto rights over certain key decisions, enhanced voting rights, or additional consent requirements to prevent unfair prejudice.

Information rights are another essential protection. These provisions ensure that shareholders receive regular financial information, management accounts, and updates on the company’s performance, even if they are not involved in day-to-day management.

Restrictive covenants

Restrictive covenants are designed to protect the business if a shareholder becomes involved with a competing venture. Non-compete and non-solicit clauses may apply during a shareholder’s ownership and for a defined period after the shareholder exits. These clauses must be carefully drafted to ensure they are reasonable and enforceable under UK law.

Dealing with disputes and deadlock

Even with the best intentions, disagreements can arise. Deadlock provisions are critical when shareholdings are evenly split. These clauses set out mechanisms for resolving impasses, such as escalation procedures, mediation, or structured buy-out options.

Many agreements include alternative dispute resolution clauses that require mediation or arbitration before court proceedings can begin. This can save time, reduce costs, and prevent damage to business relationships.

Why taking the time matters

A well-structured shareholders’ agreement can prevent disputes before they arise, protect investments, and provide a clear framework for addressing exits and unexpected events. It allows shareholders to agree the rules of engagement while relationships are strong, rather than trying to resolve issues in the heat of a dispute.

Because every business and shareholder group is different, shareholders’ agreements should be tailored to the specific company and its objectives. Anyone considering putting one in place or reviewing an existing agreement should consult their solicitor to ensure the document accurately reflects their interests and is consistent with the company’s Articles of Association.
