The architecture of a shareholders' agreement: why standard templates are your biggest risk

Of all the documents drafted in a growing company, the shareholders' agreement is the one most often borrowed, rarely read and almost never adapted. When a dispute arises — over an exit, a funding round or a departing shareholder — the parties discover that the agreement was written for a different situation, for different people and for a different stage of the company.

Most shareholder disputes we see stem from one of three structural problems in the drafting:

• **The agreement is calibrated to the wrong reality.** It regulates a company with three equal founders, when in fact the company has a majority owner, a passive investor and an operational partner with different time horizons.
• **The agreement and the articles of association contradict each other.** Decision-making forums, qualified majorities and redemption mechanisms sit in different documents and point in different directions.
• **The agreement lacks mechanisms for what actually happens.** Deadlocks, leaver events, partial exits and secondary sales are not addressed at all — or are addressed by generic clauses with no connection to how the company is actually run.

The result is that, at the moment it is needed, the agreement either has no answer or has an answer none of the parties can accept.

A well-constructed shareholders' agreement does not start with the clauses but with the decision-making architecture. Which matters are decided by the general meeting, which by the board of directors and which at management level? Which matters require unanimity, a qualified majority or a specific approval circle (reserved matters)?

For companies with external capital, the list of reserved matters is the single most negotiated section — and the section where template agreements consistently fall short. A typical list should cover capital structure, material investments, the appointment of key personnel, changes to the business plan, the incurrence of significant debt, related-party transactions and the entry into agreements above a defined threshold.

The liquidity clauses make up the agreement's exit architecture. Three instruments work together:

• **Tag-along** gives the minority the right to come along when the majority sells — protection against being left in a company with a new, unknown majority owner.
• **Drag-along** gives the majority the right to compel the minority to come along in a sale — essential in order to deliver 100 per cent of the shares to a buyer.
• **Right of first refusal (ROFR)** gives existing owners a pre-emption right over shares a shareholder wishes to sell externally.

All three must be calibrated together. A drag-along without a threshold does not protect the minority. A ROFR without a deadline blocks transactions. A tag-along without a pricing mechanism opens the door to valuation disputes.

In companies with two equally weighted shareholder blocks, deadlock is not a hypothetical risk — it is a probable future event. The agreement should set out in advance what happens when the board or the general meeting cannot agree on a material matter.

The most common mechanisms — escalation to an independent chair, mediation, Russian roulette, Texas shoot-out — suit different ownership structures. What matters is not which mechanism is chosen, but that one exists and that it can actually be implemented without destroying the company.

For companies with operational founders, vesting of founder shares is one of the most important protective features for the other owners. A founder who leaves the company after eighteen months should not retain the same shareholding as a founder who works for ten years.

Leaver provisions usually divide departures into *good leaver* (illness, death, termination by the company without cause) and *bad leaver* (voluntary departure within the vesting period, material breach of contract). The financial consequences should be clear, mechanical and hard to argue over.

Finally: the shareholders' agreement is an agreement between the parties, not part of the company's constitution. Anything intended to bind third parties — pre-emption clauses, consent requirements, rights of first refusal — must also be set out in the articles of association.

When the two documents are out of step, the most complicated disputes arise: situations where what is formally valid under company law conflicts with what is contractually binding. A well-constructed shareholders' agreement avoids this by aligning the two documents — technically and legally — from day one.

A shareholders' agreement is, in short, not a document to copy. It is an architecture to design — for the specific company, the specific ownership circle and the specific time horizon.
