# What Is Mandatory Offer?

> A mandatory offer is a legal requirement—common in some European jurisdictions—that an acquirer who crosses a ownership threshold must bid for remaining shares on regulated terms.

**Mandatory offer** is a regulatory obligation requiring an acquirer who reaches a specified ownership level to make a public offer to purchase remaining shares under prescribed pricing and process rules.

### How it works

Takeover regimes— notably in the UK, EU member states, and other markets—define control thresholds (often 30% voting rights). Crossing the threshold via purchase or concert-party action triggers a mandatory bid for all outstanding shares unless exemptions apply.

Offer price floors typically reference recent trading prices or prior deal prices—protecting minorities from a control premium captured only by sellers who negotiated the block sale. Timelines, disclosure, and regulator approval govern the process.

US private company venture financings generally operate under contractual [drag-along](/glossary/drag-along) and charter terms instead of statutory mandatory offers. The concept surfaces when:

- A VC-backed startup is acquired by a European listed company
- Shareholders hold securities in foreign listed entities
- Take-private transactions touch multi-jurisdiction cap tables

### Why it matters

- **Founders:** Your earnout or rollover in a cross-border deal may interact with mandatory offer timing—legal counsel coordinates closing sequences.
- **Investors:** Acquirers modeling control stakes must include full float purchase costs, not just negotiated blocks.

### Common mistake

Assuming a negotiated 51% purchase avoids buying minorities. In regulated markets, mandatory offer law may require a broader bid regardless of private deal terms.

## FAQ

### What is mandatory offer in simple terms?

When someone buys enough stock to gain control in certain markets, law may force them to offer to buy everyone else's shares at a fair minimum price—protecting minority shareholders from being trapped after a control shift.

### Why does mandatory offer matter?

Acquirers must budget for buying out minorities, not just control stakes. Founders with stock in EU-listed acquirers may receive liquidity via mandatory offer processes after a control transaction.
