Franco-British shareholders' agreements: essential clauses for securing investments

Against a backdrop of growing cross-border investment between France and the UK, the shareholders' agreement, often referred to as a shareholder agreement, is a key legal tool for corporate transactions.

It is frequently used in merger, mergers and acquisitions (M&A), fundraising, or restructuringoperations for businessesoperating in multiple markets.
This contractual document helps structure relationships between shareholders, protect investors, and anticipate deadlock or exit scenarios in a market constantly evolving.

This practical guide offers an educational and structured overview of the essential clauses to include in a Franco-British shareholders' agreement, as well as the key legal considerations identified by practitioners and analysts in international business law.

‍

What is a shareholders' agreement in a Franco-British context?

‍

A shareholders' agreement is a contract entered into by all or some of a company's shareholders, separate from the articles of association.
It serves as a key governance tool throughout the life of businesses, particularly duringmergers, external growth, or when new investors enter the market.

Its purpose is to supplement the articles of association by organizing:

• corporate governance and the distribution of powers,
• terms for shareholder entry and exit,
• protection of financial and strategic interests,
• preventing conflicts duringsensitive transactions (divestitures, mergers, restructuring).

In a Franco-British context, this agreement must navigate two different legal cultures :
French civil law, which is heavily regulated by statute, and English law, which is based on contractual freedom and the practices of financial markets.

‍

Major differences between French and English law

‍

Governance and quorum rules

‍

Under French law, the conduct and validity of meetings are governed by mandatory legal requirements, particularly regarding quorum and majority thresholds.
These rules apply to all companies, including duringcomplex corporate transactions .

Under English law, rules are often more flexible and largely determined by the contract and the articles of association, which offers greater flexibility in market transactions.

Key consideration
In a Franco-British shareholders' agreement, it is essential to tailor governance clauses to the law of the issuing company, while taking into account the expectations of international investors and trends in the mergersmarket.

‍

Exit clauses: drag-along and tag-along

‍

Exit clauses are a primary concern for investors, particularly during mergers, divestitures, or mergers & acquisitions.

• Drag-along clause
  This allows majority shareholders to force minority shareholders to sell their shares in the event of a total sale of thecompany.
• Tag-along clause
  This protects minority shareholders by allowing them to sell their shares under the same conditions as the majority shareholder during a change of control transaction.

Key points to define

• price calculation method,
• definition of change of control,
• trigger thresholds,
• payment terms.

Certain clauses commonly accepted in Anglo-Saxon markets can be challenged or unenforceable under French law if they are not sufficiently regulated.

‍

Right of first refusal

‍

The right of first refusal grants existing shareholders a priority right to acquire shares in the event of a transfer, a particularly strategic mechanism in corporate transactions andbusinessrestructurings.

• In France, this right may be provided for by law, the articles of association, or a shareholders' agreement.
• In the United Kingdom, it is primarily contractual and must be expressly stipulated.

The drafting must precisely specify:

• notification deadlines,
• submission procedures,
• financial terms, in line with current market realities.

‍

Confidentiality and non-compete clauses

‍

Confidentiality and non-compete clauses are designed to protect the economic value of thecompany, particularly following a merger or acquisition.

• Under French law, these clauses are subject to mandatory legal principles : proportionality, limited duration, and a specific scope.
• Under English law, they can be broader in scope, but remain subject to judicial review in the event of a dispute.

An excessive imbalance can lead to partial or total nullity, with significant consequences foremployment, strategy, and stability of the companies involved.

‍

Bilingual shareholders' agreements: risks and best practices

‍

The presence of international investors in multiple markets frequently leads to bilingual drafting (French/English) of the agreement, particularly in mergertransactions.

‍

Avoid literal translations

‍

A legal term can have different effects depending on the language and the jurisdiction.
A literal translation can alter the actual legal scope of a clause and create uncertainty in corporate transactions.

‍

Determine the governing version

‍

The agreement must clearly state which language version prevails in the event of a discrepancy in interpretation.

‍

Ensure legal equivalence

‍

The goal is not word-for-word similarity, but equivalence of legal effect in each system, in accordance with the best practices in international business law.

‍

Governing law and jurisdiction

‍

A Franco-British shareholders' agreement must include:

• the governing law (French or English),
• the appropriate jurisdiction in the event of a dispute.

‍

Practical implications

‍

• A clause valid under English law may be deemed void or unenforceable by a French court.
• English law offers robust contractual certainty, which is often valued in market transactions, though certain French obligations may limit enforcement.

‍

International arbitration

‍

Arbitration is often preferred for cross-border transactions for:

• its confidentiality,
• its flexibility,
• its international nature.

‍

General recommendations

‍

• Anticipate conflicts when drafting the agreement, particularly in merger or mergers.
• Prioritize clear, precise, and balanced clauses.
• Regularly update the agreement to reflect legal and economic developments as well as market trends.
• Work with advisors who have expertise in French-British comparative law and the complexities of corporate transactions.

‍

Conclusion

‍

The Franco-British shareholders' agreement is a strategic tool for securing investments and corporate operations.
Drafting one requires a perfect understanding of both French and English law, heightened linguistic vigilance, and rigorous anticipation of crisis scenarios.

A well-structured agreement allows companies to secure their operations, support their growth in international markets , and limit the risk of litigation related to mergers, acquisitions , and restructurings.
