Shareholders' Agreements: Key Clauses You Shouldn't Overlook
April 2026 · 7 min read
Most company disputes that we are asked to help resolve start the same way: an event happens that the shareholders' agreement did not anticipate, or a clause that no one read closely turns out to be ambiguous. A shareholders' agreement is one of the most important commercial documents a private company will sign. Knowing which clauses really matter, and how to draft them, is critical.
Why a shareholders**'** agreement matters
A shareholders' agreement is a binding contract between the shareholders of a company that supplements the company constitution. It governs:
- The rights and obligations of shareholders to each other
- How the company is managed and controlled
- What happens when shareholders want to exit, transfer their shares, or are forced out
- How disputes between shareholders are resolved
It is the fundamental document for managing the relationships between shareholders, particularly when those relationships are complex (multiple founders, external investors, family members).
Capital and shareholding
Confirms each shareholder's holding, the company's capital structure, and any classes of shares with different rights.
Decision-making
Defines the matters that require a particular level of approval, including:
- Ordinary board decisions (majority of directors)
- Reserved matters requiring unanimous board approval
- Shareholder reserved matters requiring shareholder approval (often by a special majority)
The reserved matters list is one of the most heavily negotiated parts of any shareholders' agreement. It typically includes major capital decisions, debt incurrence, sale of material assets, changes to the constitution, related-party transactions and other matters that affect minority shareholders.
Board composition
Who has the right to appoint directors? What are the rules on quorum, conflicts and proxies? How are independent directors appointed?
Information rights
What information are shareholders entitled to see? Quarterly accounts? Audited statements? Board papers? The level of access often varies depending on the size of the holding.
Funding obligations
Are shareholders required to fund future capital calls? On what terms? What happens to shareholders who do not participate (anti-dilution, dilution penalties)?
Pre-emptive rights
When new shares are issued, do existing shareholders have first right to subscribe in proportion to their holdings? Almost always yes, but the mechanics vary.
Share transfers and pre-emption
Can shareholders sell their shares? What restrictions apply? Pre-emptive rights typically require the seller to first offer the shares to existing shareholders before transferring to a third party.
Tag-along and drag-along rights
Tag-along rights. If a major shareholder sells, can minority shareholders force their shares to be included on the same terms?
Drag-along rights. If a defined majority wants to sell to a third party, can they force the minority to sell too on the same terms?
Good leaver / bad leaver
For shareholders who are also employees or founders, what happens to their shares if they leave? Vesting, forfeiture and buyback provisions often apply.
Restraints
Confidentiality, non-compete and non-solicit obligations on shareholders.
Deadlock and dispute resolution
Where shareholders cannot agree on a major decision, how is the deadlock resolved? Options include mediation, arbitration, expert determination, "Russian roulette," "Texas shoot-out," and forced sales. The right answer depends on the company.
Exit mechanisms
How will the parties achieve liquidity? IPO? Trade sale? Buyback? Some shareholders' agreements include obligations to use best endeavours to achieve a liquidity event by a defined date.
Anti-dilution protection
For investors, protection against down rounds (issues of new shares at lower valuations than they paid).
Drafting principles
Anticipate the dispute, not just the deal. The agreement should answer the questions that will come up in five years, not just the ones being negotiated today.
Be specific about percentages and thresholds. "Majority" and "supermajority" need clear definition.
Match the constitution. Inconsistencies between the agreement and the constitution create real problems.
Plan for changes in shareholding. What happens if a shareholder dies, becomes incapacitated or is bankrupted?
Address tax. Many provisions (such as forced transfers) have tax consequences. Address them.
Common pitfalls
- Generic templates that do not reflect the actual deal
- Reserved matters lists that are too narrow, leaving minority shareholders unprotected
- Reserved matters lists that are too broad, paralysing decision-making
- Drag-along rights without minimum price protection
- Pre-emptive rights that do not match the realities of how the company actually raises capital
- Restraints that are unenforceable because they are too broad
- Failure to update the agreement as the company evolves
