This article is for Irish startup founders and business owners with multiple shareholders who need to protect their interests beyond the basic company constitution.
If you're wondering when you need a shareholder agreement, what protections minority shareholders should have, or how to handle investment rounds and exits fairly, this guide covers essential provisions like decision-making rights, transfer restrictions, and exit mechanisms that prevent costly disputes down the line.
Key Takeaways
Negotiate shareholder agreements at incorporation or before investment rounds when interests align, not during disputes when positions harden.
Shareholder agreements require unanimous consent to amend, protecting minority shareholders from majority rule changes that eliminate their protections.
Include reserved matters requiring minority approval for fundamental decisions like share issuance, director appointments, and constitutional amendments.
Establish clear transfer restrictions with pre-emption rights, drag-along provisions, and tag-along rights to control who becomes a shareholder.
Define exit valuation methodologies and good leaver versus bad leaver treatment before disputes arise to prevent costly litigation.

Do I need a shareholder agreement if I already have a company constitution?
Yes, you should have a shareholder agreement even with a constitution because the constitution has significant limitations. The constitution can be amended by just 75% approval (allowing the majority to override minority protections), must be filed publicly, and doesn't bind shareholders personally for obligations like non-compete provisions.
When is the best time to put a shareholder agreement in place?
The best time is at incorporation or before your first investment round, when everyone is aligned around building the company rather than protecting individual positions. Negotiating becomes exponentially harder once disputes emerge or interests diverge, so early timing leads to more reasonable terms.
What's the difference between a founders agreement and a shareholder agreement?
A founders agreement is appropriate at incorporation stage and addresses founder equity splits, vesting schedules, and early governance between founders. A shareholder agreement is the "big sister" that comes later when you bring in external investors, establishing more serious governance rights and exit protections for outside parties.
Can the majority shareholders change a shareholder agreement without my consent?
No, shareholder agreements require unanimous consent to amend, unlike the company constitution which only needs 75% approval. This is one of the key protections for minority shareholders - the majority cannot unilaterally change the rules that protect your interests.
What decisions should require my approval as a minority shareholder?
Your shareholder agreement should include "reserved matters" requiring your approval despite your minority position, such as issuing new shares, changing the company's business nature, appointing or removing directors, entering material transactions above certain thresholds, or incurring significant debt. These provisions prevent the majority from taking fundamental actions that materially affect your interests without your consent.
What happens if a founder wants to leave the company early?
The shareholder agreement should include exit provisions defining valuation methodology and "good leaver vs. bad leaver" treatment, which affects both the price and payment terms. Founder vesting provisions typically require founders to earn their shares over time, so early departures may result in forfeiting unvested shares.
How do I protect myself from being diluted when the company raises new funding?
Include pre-emption rights in your shareholder agreement, giving you the right to participate in new share issuances pro-rata to maintain your percentage ownership. Anti-dilution mechanisms like weighted average adjustments can also protect you in down-round financing situations where shares are issued below previous valuations.
What information am I entitled to receive as a minority shareholder?
Your shareholder agreement should guarantee information rights including monthly or quarterly management accounts, annual audited financial statements, business plans and budgets, material transaction notifications, board meeting minutes, and access to company books and records. These rights allow you to monitor your investment even without board representation.
