Who should read this?

This article is for Irish startup founders and company directors who need to control who can own shares in their business.

If you're wondering how to prevent unwanted investors from buying into your company, protect founders from losing control, or set up the right restrictions before raising funding, this guide covers pre-emption rights, board approval mechanisms, and what your constitution must include to keep your cap table clean.

Key Takeaways

• Your constitution must include pre-emption rights and board approval requirements to prevent unwanted shareholders from acquiring shares.
• Transfers that breach constitutional restrictions are automatically void under Section 84(2), protecting your company without court intervention.
• Tag-along rights protect minority shareholders while drag-along rights let majority holders force minorities to join approved sales.
• Investment agreements layer additional restrictions onto constitutional provisions, creating multiple protection levels as you raise capital.
• Removing transfer restrictions requires special resolution approval and typically only happens for public listings or major funding rounds.

Frequently Asked Questions

Can shareholders freely sell their shares to anyone they want?

No, not if your company has share transfer restrictions in place. Private companies in Ireland can legally restrict share transfers through their constitution under Section 84 of the Companies Act 2014, and most startup constitutions include these restrictions to control who becomes a shareholder.

What are pre-emption rights and how do they work?

Pre-emption rights give existing shareholders the first opportunity to buy shares before they can be sold to external buyers. When a shareholder wants to sell, they must first offer the shares to other shareholders (typically for 14-30 days), and only if they decline can the shares be offered externally at the same terms.

Do I need board approval to transfer my shares?

Most startup constitutions require board approval for all share transfers, giving directors control over who joins the shareholder register. Directors must evaluate whether the proposed buyer aligns with the company's strategic direction and can work constructively with existing shareholders, always acting in the company's best interests rather than personal preferences.

What happens if I transfer shares without following the restrictions?

The transfer is automatically void under Section 84(2) of the Companies Act 2014. The company can refuse to register the transfer, meaning the buyer never becomes a registered shareholder with voting or dividend rights, and you remain the shareholder with all associated rights and obligations.

Can I transfer shares to my spouse or children without restrictions?

Most constitutions exempt certain family transfers from pre-emption and approval requirements, including transfers to spouses, family trusts, or transfers upon death to beneficiaries. However, these exemptions are typically narrowly drafted, so you should check your specific constitution to confirm what's permitted.

What are drag-along rights and why do investors want them?

Drag-along rights allow majority shareholders (typically holding 50% or more) to force minority shareholders to join in approved sales to third parties. This prevents small shareholders from blocking valuable exit opportunities, which is essential because acquirers often require 100% ownership to complete transactions.

How are share prices determined when existing shareholders want to buy under pre-emption rights?

Your constitution should specify the valuation method, with common approaches including independent valuation by a qualified accountant, formula methods based on recent financial results, or the price from the most recent arms-length sale. Most constitutions require independent valuation to ensure fairness between buying and selling shareholders.

What risks does my company face without proper transfer restrictions?

Without restrictions, shareholders can freely transfer shares to anyone, including competitors who could gain access to confidential information. You lose the ability to manage shareholder composition and maintain a cohesive vision, and most venture capital investors refuse to invest in companies without proper transfer restrictions because messy cap tables create complexity during due diligence.

Can we remove transfer restrictions if we need to later?

Yes, but it requires a special resolution approval from shareholders under Section 85 of the Companies Act 2014. Removal typically happens only for specific strategic reasons such as preparing for a public listing (which requires freely transferable shares), corporate simplification, or meeting new investor requirements during significant funding rounds.
