How to Do a Franco-german Cross-border M&A in France (2026): Step-by-step Legal Checklist for Buyers & Sellers

France Germany M&A transactions face a more demanding regulatory environment in 2026, with parallel merger control clocks, sharpened foreign direct investment (FDI) screening and mandatory employee-representative consultation running concurrently on both sides of the Rhine. This guide sets out the procedural sequence a deal team must follow when the target sits in France and the buyer is German (or the reverse), from the first jurisdictional quickcheck through to closing and post-closing integration. It is written for in-house counsel, corporate buyers and sellers, and their external advisers who need explicit filing triggers, dossier contents, timetables and durations rather than high-level strategy.

Every threshold, deadline and statutory reference should be verified against the primary sources listed at the end, because thresholds and procedures are periodically revised. Treat all sample clause language and checklists as models to verify with counsel before use.

Overview, scope, applicability and a quick decision map

A france germany m&a deal rarely involves a single filing. Depending on turnover, sector and structure, a transaction can trigger French merger control, German merger control, EU merger control, French FDI screening, German FDI screening and separate labour consultation processes, several of which run in parallel with independent clocks. The purpose of this overview is to help a deal team map which regimes apply before committing to a timetable.

When this guide applies (target in France, buyer in Germany or vice versa)

This checklist applies where the transactional target, the operating business, shares or assets being acquired, is located in France and the acquirer is based in Germany, and it is equally usable where roles are reversed. The core France Germany M&A analysis is the same: identify each authority with jurisdiction, sequence the filings, and build the conditionality and standstill effects into the share purchase agreement (SPA). The guide assumes a controlling acquisition (sole or joint control), which is the trigger concept under both the EU Merger Regulation and national regimes.

Quick decision map: merger control vs FDI screening vs labour issues

• Merger control. Ask first whether EU thresholds under Regulation (EC) No 139/2004 are met. If they are, the European Commission generally has exclusive jurisdiction; if not, test French and German national thresholds separately.
• FDI screening. Independent of competition law. Ask whether the French target operates in a protected sector and whether the German buyer meets the control test that triggers a mandatory filing with the French authorities.
• Labour consultation. Independent again. French employee-representative consultation via the Comité social et économique (CSE) and German Betriebsrat consultation must be planned early because they can gate signing or closing.

Eligibility and triggers, when filings are required in France Germany M&A

The eligibility analysis is the foundation of any france germany m&a timetable. Get it wrong and you either file where you need not, delaying the deal, or fail to file where you must, exposing the parties to fines and unwinding risk.

EU Commission (EUMR) thresholds, when EC jurisdiction applies

The EU Merger Regulation confers jurisdiction on the European Commission where a concentration has an EU dimension measured by combined aggregate worldwide and EU-wide turnover thresholds set out in Council Regulation (EC) No 139/2004. Where those thresholds are met, the concentration must be notified to the Commission and, in principle, is not separately notifiable to French or German national authorities under the one-stop-shop principle. The practical consequence for a France Germany M&A deal team is that the EU test must be run before any national test, because a positive result removes the national competition filings from the critical path.

Note that referral mechanisms between the Commission and Member States can alter which authority ultimately reviews a deal, so confirm the position with counsel.

French thresholds and notification practice (Autorité de la concurrence)

Where the EU dimension is absent, French merger control applies through the Autorité de la concurrence on the basis of turnover thresholds achieved in France by the undertakings concerned, as set out in the Code de commerce. Notification is mandatory and suspensory: the transaction may not close before clearance. In practice the Autorité encourages pre-notification contact so that the formal dossier is complete when the review clock starts.

German thresholds and notification practice (Bundeskartellamt)

On the German side the Bundeskartellamt exercises merger control under the Act against Restraints of Competition (Gesetz gegen Wettbewerbsbeschränkungen, GWB) on the basis of domestic and worldwide turnover thresholds. Notification is likewise mandatory and suspensory. Both national reviews can run simultaneously, and coordinating the two dossiers, using consistent market definitions, turnover figures and remedy positions, is a central task of antitrust counsel in a France Germany M&A transaction.

FDI screening triggers in France (scope, sectors, control tests)

French FDI screening operates independently of competition law under the regime set out in the Code monétaire et financier and administered through the French Ministry of the Economy (Direction générale du Trésor). It applies where a foreign investor acquires control of, crosses defined participation levels in, or acquires certain assets of a French entity active in a protected sector, including defence, dual-use goods, critical technologies, health, energy, water, transport, telecommunications and other sensitive activities. Because Germany is an EU Member State, a German buyer will not always face the same intensity of review as a non-EU acquirer, and certain participation-threshold tests are relaxed for EU/EEA investors, but sector-sensitive targets can still require a mandatory filing.

Germany applies its own parallel screening regime under the Außenwirtschaftsgesetz (AWG) and Außenwirtschaftsverordnung (AWV) for inbound investment into German targets. The control tests, sector lists and thresholds must be checked against the current published rules for each transaction.

Step-by-step deal checklist: pre-signing to closing

The following numbered sequence sets out the procedural spine of a France Germany M&A transaction. Steps overlap deliberately, due diligence, pre-notification engagement and dossier drafting should run in parallel to compress the overall timetable.

1. Pre-deal screen and jurisdictional quickcheck. Lead counsel for buyer and seller, working in parallel with antitrust counsel, run the EU/French/German merger tests and the French and German FDI tests against turnover and sector data. Output: a filing map identifying every authority with jurisdiction.
2. Regulatory and legal due diligence. The buyer’s due diligence team, supported by specialists, examines FDI-relevant assets (technology, IP, security-sensitive contracts), export-control licences, employment structures, data protection and material contracts. Flag any asset that could convert a discretionary FDI review into a mandatory one.
3. Pre-notification engagement. Lead antitrust counsel opens informal contact with the Autorité de la concurrence, the Bundeskartellamt and/or the European Commission where appropriate, and with the French FDI authority for sector-sensitive targets, to test the completeness of the intended dossiers before the formal clock begins.
4. Prepare the notification and FDI dossiers. Antitrust counsel and the corporate team, with translators and, where needed, economic experts, assemble the merger notification and FDI dossiers so that consistent data underpins each filing.
5. File the national merger notifications. Designated filing counsel submit the French and/or German notifications. This is Day 0 for each national review clock once the filing is deemed complete.
6. Run the clearance clock (Phase I). The competition authority reviews. Respond promptly to requests for information; a gap in the dossier can stop the clock.
7. FDI review. In parallel, the French FDI authority conducts its initial assessment and, if it opens an in-depth review, examines the detailed dossier and any conditions.
8. EU review (if triggered). Where EU thresholds are met, the European Commission conducts Phase I and, if serious doubts arise, Phase II.
9. Clearance and remedies negotiation. Where an authority identifies concerns, the parties negotiate structural or behavioural remedies. This step can extend the timetable materially.
10. Closing. Once every condition precedent is satisfied, competition clearances, FDI authorisations and completed labour consultations, the parties complete the transaction.

Pre-signing: due diligence focus for cross-border risk

Pre-signing diligence in a France Germany M&A deal must be regulatory-led, not just financial. Map export-control classifications, dual-use licences, government contracts and critical-technology IP, because these determine FDI exposure. Confirm the workforce structure in both countries so that the CSE and Betriebsrat consultation timetables can be built early. Assess data and cybersecurity posture, since digital infrastructure can be a sensitive sector. The output of pre-signing diligence should feed directly into the conditions precedent and the interim covenants in the SPA.

Signing: conditions precedent, exclusivity and interim covenants

At signing, the SPA should contain conditions precedent for each required clearance, French merger, German merger, EU merger and French FDI, with a defined long-stop date. Exclusivity, deposit arrangements and interim covenants preserving the target’s ordinary course of business between signing and closing protect the buyer during the review period. Reverse break fees and allocation of remedy risk should be negotiated here, not left to closing.

Pre-closing filings: merger notifications, FDI filings and labour notices

Between signing and closing the parties file the notifications identified in the quickcheck and complete employee-representative consultation. Because both French and German merger control are suspensory, and FDI authorisation is a precondition to acquiring control of a protected French target, none of these can be treated as post-closing formalities. Sequence them so that the longest expected review governs the timetable.

Closing and post-closing remedial steps

Closing occurs once all conditions are satisfied. Post-closing steps include implementing any agreed remedies (for example divestments or behavioural commitments), filing integration notices, and completing corporate registrations. Where remedies were accepted, monitor compliance deadlines closely, enforcement in both jurisdictions is robust.

Mandatory step / who / duration timetable

Required documents and dossier checklist

Each filing in a France Germany M&A transaction has its own dossier. Preparing consistent underlying data, turnover figures, market definitions and corporate structure, once, then adapting it to each form, avoids contradictions that authorities will notice when they cross-reference filings.

Templates and model clauses to prepare in advance

Prepare, in advance and labelled as models to verify with counsel, a conditions-precedent checklist, a clearance condition covering all applicable merger and FDI approvals, interim covenant language, and CSE/Betriebsrat information memoranda. Having these drafted before signing shortens the gap between term sheet and executed SPA.

Timeline and deadlines, sample coordinated timetables

The overall duration of a france germany m&a deal is driven by the longest concurrent review, not the sum of all reviews. Because national merger reviews and FDI reviews run in parallel, coordination, not addition, governs the timetable.

• National filings only (France or Germany). Pre-notification and dossier preparation of roughly 2–4 weeks, followed by a Phase I review (approximately 25 working days in France or one month in Germany), gives a realistic 6–8 week path to clearance absent complications.
• Dual France–Germany filings. Both Phase I reviews run in parallel at roughly a month each; the binding path is the slower authority plus any information requests, typically several weeks including preparation.
• EC + national + FDI concurrent. Where the EU dimension is met, the Commission’s Phase I of 25 working days (extendable, and further extendable to a Phase II of 90 working days) runs alongside the French FDI review, which can take several weeks initially and longer if opened in-depth. Plan for two to four months in straightforward cases and materially longer if remedies or an in-depth FDI review arise.

Two structural effects dominate the timetable. First, merger control is suspensory, so closing cannot precede clearance. Second, information requests can stop or reset the review clock in practice; a complete dossier at Day 0 is the single most effective way to protect the timetable in a France Germany M&A deal.

Costs and fees

*Neither the French nor the German competition authority charges a fee at the point of filing a standard notification; the Commission does not charge an EUMR filing fee. Verify current cost regimes before budgeting, and obtain fee quotes from advisers for each mandate.

What changes in 2026, regulatory and practical updates

FDI procedural updates (France and Germany)

FDI screening on both sides has continued to broaden in scope and intensity in recent years. The practical effect is earlier and more detailed dossiers, greater scrutiny of financing and ultimate ownership, and closer attention to critical-technology and data assets. In parallel, the EU’s foreign subsidies regime and the FDI screening cooperation framework add cross-border coordination layers. Deal teams should assume that FDI review, not merger control, can be the binding constraint on the France Germany M&A timetable for sector-sensitive targets. Confirm the latest sector lists and thresholds against the current French and German rules for each transaction.

Merger control focus sectors

Competition authorities in France and Germany, and the European Commission, continue to concentrate scrutiny on technology, biotech, health and critical infrastructure. The likely practical effect is more frequent information requests and a higher probability of remedies where the parties overlap in these sectors. Early economic analysis is a prudent investment in such deals.

Common pitfalls and how to avoid them

Notification timing and information gaps

• Treating filings as post-signing formalities. Merger control is suspensory; build clearances into conditions precedent, not the closing agenda.
• Filing an incomplete dossier. Information gaps can delay the review; complete pre-notification engagement before Day 0.
• Inconsistent data across filings. Use the same turnover figures and market definitions in the French, German and EU dossiers.

Labour and works-council missteps

• Starting consultation too late. French CSE and German Betriebsrat processes take time and can delay signing or closing.
• Overlooking co-determination. German consultation and co-determination rights under the BetrVG must be respected in substance, not just form.
• Ignoring automatic transfer rules. French employee transfer under the Code du travail applies by operation of law in qualifying asset deals.

SPA drafting errors on clearances and remedies

• Vague clearance conditions. Specify each required approval and a realistic long-stop date.
• No allocation of remedy risk. Decide who bears divestment obligations and reverse break fees before signing.
• Missing interim covenants. Preserve the target’s ordinary course of business during the review period.

Conclusion

A successful France Germany M&A transaction in 2026 is won or lost at the jurisdictional quickcheck. Identify every applicable regime, EU, French and German merger control, French and German FDI screening, and CSE and Betriebsrat consultation, before committing to a timetable, then run the reviews in parallel with complete dossiers filed at Day 0. Build each clearance into the SPA as a condition precedent with a realistic long-stop date and a clear allocation of remedy risk, and start labour consultation early. Handled in this sequence, a france germany m&a deal moves through concurrent regulatory processes with the fewest surprises and the shortest realistic path to closing.
