Mergers & Acquisitions in France: Frequently Asked Questions

French M&A transactions are among the most technically demanding in continental Europe. A buyer acquiring a French company must navigate merger control filings, mandatory employee consultation, strict securities rules and a civil law framework that differs materially from common law practice. Failing to account for any one of these layers can delay closing by months or expose the acquirer to post-closing liability worth multiples of the deal value. This article addresses the questions that international clients ask most frequently - covering deal structure, due diligence, regulatory clearance, employee rights, pricing mechanisms and post-closing disputes - so that decision-makers can enter a French transaction with a realistic picture of what lies ahead.

The first strategic decision in any French acquisition is whether to buy shares or assets. Each path carries a distinct legal profile under the Code de commerce (French Commercial Code) and the Code civil (French Civil Code).

A share purchase (cession de titres) transfers the entire legal entity, including all its liabilities - disclosed and undisclosed. The buyer steps into the shoes of the seller with respect to every obligation the target has ever incurred. French courts have consistently held that representations and warranties in a share purchase agreement do not automatically cap the seller';s liability for fraud or wilful concealment, which means a poorly drafted guarantee de passif (liability guarantee) can leave the buyer exposed even where a cap is agreed.

An asset purchase (cession de fonds de commerce) transfers a defined bundle of assets - goodwill, client lists, equipment, intellectual property - without automatically transferring liabilities. However, Article L.141-1 of the Code de commerce imposes a mandatory publication and creditor opposition procedure. Creditors of the seller have ten days after publication in a legal gazette to oppose the sale, and the purchase price is blocked in escrow for a further period to satisfy any valid claims. This procedure adds four to six weeks to the timeline and is frequently underestimated by buyers accustomed to Anglo-American asset deals.

A merger by absorption (fusion-absorption) under Articles L.236-1 to L.236-24 of the Code de commerce dissolves the absorbed company and transfers all its assets and liabilities by universal succession to the absorbing entity. This structure is common for intra-group reorganisations but requires shareholder approval at an extraordinary general meeting, an auditor';s report on the exchange ratio and, in cross-border mergers, compliance with Directive 2019/2121 as transposed into French law.

In practice, it is important to consider that the choice of structure also determines the applicable transfer taxes. Share transfers in French SAS or SARL entities attract a 3% registration duty on the price above a small allowance, while transfers of a fonds de commerce attract duties on a sliding scale that can reach 5% on the portion of the price above EUR 200,000. These costs are not trivial on mid-market deals and should be modelled before the letter of intent is signed.

A common mistake made by international buyers is to import the structure used in their home jurisdiction without first stress-testing it against French tax and labour law. A structure that is tax-neutral in Germany or the United Kingdom may generate unexpected French withholding tax or trigger mandatory employee information-and-consultation rights that delay closing.

Due diligence on a French target follows the same broad categories as elsewhere - legal, financial, tax, commercial and technical - but several French-specific areas require dedicated attention.

Labour law exposure is the single most common source of post-closing surprises. France';s Code du travail (Labour Code) grants employees extensive protections. Collective bargaining agreements (conventions collectives) apply automatically to the target';s sector and may impose obligations that are more generous than the statutory minimum. A buyer must identify which convention collective applies, whether the target has a works council (comité social et économique, or CSE), and whether any collective agreements have been denounced or are in the process of renegotiation. Unresolved labour disputes, unpaid overtime claims and misclassified independent contractors are recurring issues that surface only during deep-dive diligence.

Environmental liability under the Code de l';environnement (Environmental Code) is another area where French law imposes strict obligations on site operators. If the target operates classified installations (installations classées pour la protection de l';environnement, ICPE), the buyer inherits the regulatory obligations attached to those installations. Remediation orders issued by the préfet (regional government authority) bind the operator regardless of when the contamination occurred.

Intellectual property registered with the Institut national de la propriété industrielle (INPI) must be verified for ownership, encumbrances and maintenance. A non-obvious risk is that IP developed by employees during their employment belongs to the employer under Articles L.111-1 and L.611-7 of the Code de la propriété intellectuelle (Intellectual Property Code), but only if the employment contract and internal procedures are properly documented. Gaps in documentation can cloud title.

Tax due diligence must cover the target';s exposure to the cotisation sur la valeur ajoutée des entreprises (CVAE), the French business value-added contribution, as well as transfer pricing positions and any ongoing tax audits. The French tax authority (Direction générale des finances publiques, DGFiP) has a three-year standard limitation period for income tax reassessments, extendable to ten years in cases of fraud.

Data protection compliance under the RGPD (Règlement général sur la protection des données, the French implementation of the GDPR) and oversight by the Commission nationale de l';informatique et des libertés (CNIL) is increasingly scrutinised in tech and data-driven acquisitions. Buyers should verify whether the target has filed required notifications, conducted data protection impact assessments and appointed a data protection officer where mandatory.

Merger control is a threshold-driven process. A transaction that meets the relevant thresholds requires mandatory pre-closing notification and clearance. Closing before clearance is granted constitutes gun-jumping, which French and EU authorities treat as a serious infringement.

At the EU level, the EU Merger Regulation (Council Regulation (EC) No 139/2004) applies where the combined worldwide turnover of all parties exceeds EUR 5 billion and the EU-wide turnover of each of at least two parties exceeds EUR 250 million, unless each party achieves more than two-thirds of its EU-wide turnover in a single member state. Transactions meeting these thresholds are notified to the European Commission and are subject to a Phase I review of 25 working days, extendable to 35 working days if remedies are offered. Phase II investigations can extend the process by a further 90 working days, with possible extensions.

Where EU thresholds are not met, French domestic merger control under Articles L.430-1 to L.430-10 of the Code de commerce applies if the combined worldwide pre-tax turnover of all parties exceeds EUR 150 million and the French pre-tax turnover of each of at least two parties exceeds EUR 50 million. The competent authority is the Autorité de la concurrence (French Competition Authority). Phase I review takes 25 working days. Phase II can extend to 65 working days, with possible extensions for remedies or information requests.

A non-obvious risk in French transactions is the referral mechanism. Even where EU thresholds are met, the European Commission may refer a case to the Autorité de la concurrence if the transaction primarily affects competition in France. Conversely, France may request that the Commission examine a transaction that falls below EU thresholds but raises cross-border concerns.

Practical scenario one: a US private equity fund acquires a French industrial group with EUR 300 million in French revenues. The transaction clears EU thresholds. The Commission opens a Phase I review. The fund must not close, transfer shares or exercise control until clearance is granted. Any interim management arrangements that give the buyer de facto influence over the target';s commercial decisions before clearance can constitute gun-jumping.

Practical scenario two: a mid-market strategic buyer acquires a French SaaS company with EUR 60 million in French revenues. EU thresholds are not met. The Autorité de la concurrence has jurisdiction. The buyer files a domestic notification and receives Phase I clearance within 25 working days, allowing a relatively swift closing.

Practical scenario three: a cross-border merger between two European groups with overlapping French market positions triggers both EU notification and a request by the Autorité de la concurrence for referral. The timeline extends materially, and the parties must prepare detailed market share analyses for both authorities simultaneously.

The obligation to inform and consult employees is one of the most distinctive features of French M&A law and the one that most frequently surprises foreign buyers. It is not a formality - it is a substantive procedural requirement with real consequences for deal timing.

Under Article L.2312-8 of the Code du travail, the CSE (comité social et économique) must be informed and consulted before any major decision affecting the company';s organisation, management or working conditions. An acquisition qualifies as such a decision. The CSE must receive sufficient information to deliver a reasoned opinion. It has 15 days to issue its opinion in standard cases, extendable to one month where an expert is appointed.

The Loi Florange (Law No. 2014-384), codified in Articles L.1233-57-14 to L.1233-57-20 of the Code du travail, imposes an additional obligation on buyers of a profitable establishment with 1,000 or more employees: the buyer must search for a potential acquirer before proceeding with a closure. While this obligation is more relevant to plant closures than to straightforward acquisitions, it illustrates the legislative philosophy that employee interests are a primary consideration in French corporate transactions.

A common mistake is to structure the signing and announcement of a transaction without first verifying whether the CSE consultation has been properly initiated and completed. French courts have annulled decisions taken in breach of consultation obligations, and the Tribunal judiciaire (civil court of first instance) can issue injunctions suspending the implementation of a transaction pending proper consultation. The reputational and financial cost of such an injunction - including the cost of restarting the consultation process - can be substantial.

In practice, it is important to consider that the CSE consultation must be completed before the final decision is made, not merely before closing. This means that in a share purchase, the consultation should ideally be completed before the share purchase agreement is signed, or at the very latest before the conditions precedent are satisfied. Signing subject to a condition precedent of CSE consultation completion is a common and legally sound approach, but it requires careful drafting to avoid the condition being treated as a mere formality.

The cost of the CSE';s expert (expert-comptable appointed by the CSE) is borne by the company, not the buyer. Expert fees on a mid-market transaction typically run into the low tens of thousands of euros. The expert';s report is delivered to the CSE, which then issues its opinion. The opinion is advisory - the buyer is not legally required to follow it - but ignoring a strongly negative opinion without engagement can create labour relations problems post-closing.

French M&A documentation has evolved significantly under the influence of Anglo-American practice, but it retains several civil law characteristics that affect how pricing and liability are structured.

The two dominant pricing mechanisms are locked-box and completion accounts. Under a locked-box mechanism, the price is fixed at a historical balance sheet date, and the seller gives leakage protections preventing value from being extracted between that date and closing. Under a completion accounts mechanism, the price is adjusted after closing based on the actual financial position at the closing date. French practitioners have increasingly adopted the locked-box approach for private transactions, as it provides certainty and reduces post-closing disputes. However, the locked-box mechanism requires robust financial due diligence and a clearly defined leakage concept.

Representations and warranties in French share purchase agreements are typically structured as a garantie de passif (liability guarantee) or a garantie d';actif et de passif (asset and liability guarantee). These instruments have a specific legal character under French law: they are autonomous contractual undertakings, not mere representations. The distinction matters because the remedies available for breach differ from those available under common law. Under a garantie de passif, the seller compensates the buyer for any increase in liabilities or decrease in assets relative to the position warranted, subject to agreed thresholds, caps and time limits.

The limitation period for claims under a garantie de passif is generally contractually agreed, but it cannot be shorter than the statutory minimum applicable to the underlying liability. For tax claims, the parties typically align the warranty period with the DGFiP';s reassessment window. For labour claims, the period is often set at three to five years.

Warranty and indemnity (W&I) insurance has become standard in French mid-market and large-cap transactions. Insurers active in the French market require a clean due diligence process and will typically exclude known risks, fraud and environmental contamination. Premiums on French transactions generally fall in the range of 1% to 2% of the insured amount, depending on the risk profile and deal complexity.

A non-obvious risk in French transactions is the application of Article 1641 of the Code civil (hidden defects warranty, garantie des vices cachés). In an asset purchase, the seller may be liable for hidden defects in the assets transferred even where the purchase agreement contains an "as is" clause, unless the clause is drafted with sufficient specificity to exclude this statutory warranty. French courts have shown a tendency to interpret exclusion clauses narrowly.

Post-closing disputes in French M&A transactions most commonly arise from claims under the garantie de passif, disputes over completion accounts adjustments, earn-out disagreements and allegations of misrepresentation.

French courts have jurisdiction over disputes arising from agreements governed by French law unless the parties have validly agreed to arbitration. The Tribunal de commerce (commercial court) in Paris handles the majority of commercial M&A disputes. Paris also hosts the International Chamber of Commerce (ICC) Court of Arbitration, which is the most frequently chosen arbitral institution for French cross-border M&A disputes. The ICC Rules provide for a Secretariat in Paris and allow parties to select arbitrators with French law expertise.

Arbitration clauses in French M&A agreements are generally enforceable. French arbitration law (Articles 1442 to 1527 of the Code de procédure civile, Civil Procedure Code) is considered arbitration-friendly. French courts have consistently upheld the kompetenz-kompetenz principle, allowing arbitral tribunals to rule on their own jurisdiction before courts intervene.

Earn-out disputes are a growing category of post-closing litigation in France. An earn-out is a deferred price component tied to the target';s post-closing financial performance. French courts apply Article 1104 of the Code civil, which requires parties to perform contracts in good faith. A buyer who takes post-closing decisions that artificially depress the earn-out metric - for example, by reallocating costs to the acquired entity or redirecting revenues to affiliates - may be found to have breached the good faith obligation, even where the earn-out agreement does not expressly prohibit such conduct.

Practical scenario one: a seller claims under a garantie de passif that a tax reassessment by the DGFiP constitutes a covered liability. The buyer argues the reassessment relates to a period after closing. The dispute turns on the precise drafting of the temporal scope of the guarantee and the definition of "covered liabilities." Resolution through ICC arbitration typically takes 18 to 24 months from the filing of the request for arbitration.

Practical scenario two: a completion accounts dispute arises over the classification of certain items as debt or cash. The parties'; respective accountants reach conflicting conclusions. The agreement provides for expert determination by an independent accountant. The expert';s decision is binding and final under French law, provided the expert has not exceeded their mandate.

Practical scenario three: a minority shareholder in the acquired company challenges the merger consideration as inadequate, relying on Article L.236-10 of the Code de commerce, which requires an independent appraiser';s report on the exchange ratio. The challenge is brought before the Tribunal de commerce. The court appoints its own expert to verify the valuation methodology. Such proceedings can delay the effectiveness of a merger by several months.

The risk of inaction in post-closing disputes is significant. Claims under a garantie de passif are subject to contractual time limits that are strictly enforced. Missing a notification deadline - even by a few days - can extinguish a valid claim worth millions of euros. Buyers should implement a post-closing monitoring system to track warranty periods and ensure timely notification of potential claims.

A common mistake is to treat post-closing integration as a purely operational matter and to defer legal review of emerging issues. In practice, facts that will later support a warranty claim often surface during the first six to twelve months of integration. Identifying and preserving evidence at that stage is critical to the success of any subsequent claim.

What is the most significant legal risk for a foreign buyer acquiring a French company?

The most significant risk for most foreign buyers is underestimating the scope and enforceability of French labour law obligations. The CSE consultation requirement is not merely procedural - courts have suspended transactions where it was not properly observed. Beyond the consultation, the buyer inherits all collective bargaining agreements applicable to the target';s sector, which may impose obligations on wages, working hours and redundancy procedures that are more onerous than the statutory minimum. A buyer who plans post-closing restructuring without first mapping these obligations may face injunctions, damages claims and significant reputational damage with the workforce. Engaging French employment counsel at the due diligence stage, rather than after signing, is the most effective way to manage this risk.

How long does a typical French M&A transaction take from signing to closing, and what drives the timeline?

A straightforward private share purchase with no merger control filing and a completed CSE consultation can close in four to eight weeks from signing. The timeline extends materially where merger control notification is required: a French domestic Phase I review adds at least 25 working days, and EU Phase I adds 25 to 35 working days. CSE consultation adds 15 days at minimum, and up to one month where the CSE appoints an expert. Asset purchases involving a fonds de commerce add four to six weeks for the mandatory publication and creditor opposition procedure. In complex transactions combining all of these elements, a timeline of four to six months from signing to closing is realistic. Buyers who model a shorter timeline without accounting for these procedural steps frequently face pressure to grant seller-friendly interim covenants for longer than anticipated.

When should a buyer choose arbitration over French court litigation for post-closing disputes?

Arbitration is generally preferable for cross-border M&A disputes involving parties from different jurisdictions, where confidentiality is important, or where the dispute involves complex financial or technical issues requiring specialist expertise. ICC arbitration seated in Paris offers a neutral forum, enforceable awards under the New York Convention, and the ability to select arbitrators with M&A and French law expertise. French court litigation before the Tribunal de commerce in Paris is faster and less expensive for straightforward disputes, particularly where interim relief is needed urgently - French courts can grant provisional measures within days, while an arbitral tribunal may take weeks to constitute. The choice should be made at the drafting stage, with the dispute resolution clause tailored to the specific risk profile of the transaction.

French M&A transactions reward thorough preparation and penalise shortcuts. The combination of civil law contractual mechanics, mandatory employee consultation, multi-layered merger control and strict post-closing liability regimes creates a framework that is coherent but demanding. International buyers and sellers who engage French legal counsel early - at the structuring stage rather than after heads of terms are agreed - consistently achieve better outcomes on price, timeline and post-closing risk allocation.
