Merger Control vs FDI Screening in France (2026): Do I Need to Notify, and When to Hire a Cross‑border M&A Lawyer

Any foreign acquirer targeting a French business in 2026 faces a threshold question that can make or break deal timing: do you file a merger control notification with the Autorité de la concurrence, apply for prior authorisation from the Ministry of the Economy under France’s foreign‑investment screening regime, or both? The answer turns on turnover thresholds, investor nationality, and whether the target operates in sectors France now treats as strategically sensitive, a list that has expanded materially in recent years to cover biotech, AI, semiconductors, and critical infrastructure. Getting the analysis wrong risks forced divestment, heavy administrative penalties, and a deal that unravels after signing.

This guide sets out the merger control vs FDI screening France 2026 choice dimension by dimension, delivers the side‑by‑side comparison table that competing resources omit, and identifies the exact moments when retaining a Cross‑Border M&A lawyer moves from optional to essential.

Option A: French Merger Control Filing, What It Is, When It Applies, and Who It Suits

A French merger filing is a competition‑law obligation. Its sole purpose is to prevent concentrations that would significantly impede effective competition, particularly by creating or strengthening a dominant position. It is sector‑agnostic: whether the target manufactures auto parts or develops quantum‑computing software, the analysis centres on market shares, barriers to entry, and competitive effects.

What constitutes a “concentration” in France

Under French competition law (mirroring the EU Merger Regulation framework), a notifiable concentration arises when two or more previously independent undertakings merge, or when one or more undertakings acquire direct or indirect control of the whole or part of another undertaking. Control can be acquired through share purchases, asset purchases, contractual arrangements, or any other means that confer decisive influence over strategic commercial decisions. Joint ventures that perform on a lasting basis all the functions of an autonomous economic entity also qualify.

Filing thresholds and jurisdictional tests

France operates a two‑tier system. A concentration must be notified to the Autorité de la concurrence when the combined worldwide turnover of all parties exceeds the national threshold and when at least two of the parties each achieve individual turnover in France above a second national threshold. If the higher turnover thresholds set out in Council Regulation (EC) No 139/2004 (the EU Merger Regulation, or “EUMR”) are met, and the parties do not each achieve more than two‑thirds of their EU‑wide turnover in one and the same Member State, the transaction falls under the exclusive jurisdiction of the European Commission instead.

Deal teams must run both calculations early: a miscalculation can mean filing with the wrong authority and re‑starting the clock.

Procedure and timeline

The Autorité de la concurrence operates a pre‑notification phase (informal, typically lasting days to weeks depending on market complexity), followed by a formal Phase I review and, where serious doubts about competitive harm remain, a Phase II in‑depth investigation. A standstill obligation applies: parties may not close the transaction before receiving clearance. Closing in breach of the standstill risks fines and potential unwinding of the deal.

• Phase I duration: approximately 25 working days from the date the notification is declared complete.
• Phase II duration: an additional period that can extend the total review to several months for complex cases.
• Remedies at Phase I: commitments (divestments, behavioural remedies) can resolve concerns and avoid Phase II.

Option B: Foreign Investment Screening France, Prior Authorisation from the Ministry of the Economy

Foreign investment screening France serves a fundamentally different purpose: protecting public order, national security, and economic sovereignty. The screening regime is administered by the Direction générale du Trésor within the Ministry of the Economy. Where it applies, the investor must obtain prior authorisation from the Ministry of Economy before completing the investment. Proceeding without authorisation is not merely a procedural breach, it exposes the investor to forced unwinding, nullification, and significant penalties.

Legal basis and the Ministry of Economy’s role

The French FDI regime is grounded in Article L. 151‑3 of the Monetary and Financial Code and its implementing decrees. A foreign investor, defined broadly to include any non‑French natural person or any entity not controlled by French persons, must file a request with the Minister for the Economy and obtain authorisation before making a qualifying investment. The Direction générale du Trésor handles the substantive review, assessing whether the investment threatens public order, public security, or national defence interests.

Scope: sectors and control tests

The regime applies only when two conditions are met simultaneously: the investor qualifies as “foreign” and the target entity operates in one or more sensitive sectors. The sector list has expanded steadily and, in 2026, includes activities relating to:

• Defence and national security, weapons, dual‑use goods, cryptology, intelligence activities.
• Critical infrastructure, energy, water, transport, electronic communications, public health.
• Technology and data, AI, semiconductors, cybersecurity, data hosting for sensitive operators.
• Health and biotech, medical devices, biotech activities, pharmaceutical R&D involving strategic supply chains.
• Media and press, activities contributing to the pluralism and independence of the press.
• Food security, critical food‑supply operations (added in recent amendments).

The control threshold for non‑EU/EEA investors is the acquisition of more than 25 % of voting rights in a French entity. For EU/EEA investors, the threshold is generally the acquisition of control (i.e., the ability to exercise decisive influence).

Types of administrative outcomes

The Minister may issue one of three outcomes: unconditional authorisation, conditional authorisation subject to undertakings (such as governance ring‑fencing, continuity‑of‑supply commitments, or restrictions on access to classified information), or outright prohibition. The MoE can also order an investor who has completed an investment without filing to submit a retroactive application, and can impose penalties for the breach itself.

Merger Control vs FDI Screening: Side‑by‑Side Comparison

The following table is the centrepiece of this guide. It maps every critical decision dimension across the two regimes so that deal teams can see, at a glance, which filing obligations apply and where coordination is required. For transactions involving a foreign acquirer and a French target in a sensitive sector, both columns will apply, the question is sequencing and priority.

How the two regimes interact

The two filings run on independent tracks, before different authorities, under different legal standards. Clearance from the Autorité de la concurrence does not exempt a transaction from FDI screening, and vice versa. In practice, industry observers expect an increasing number of transactions to trigger both obligations simultaneously, particularly acquisitions by non‑EU buyers in health, technology, and infrastructure sectors. Where both apply, early coordination is critical. The recommended approach for sensitive‑sector deals is to engage the Direction générale du Trésor at the pre‑signing stage (or even before a letter of intent is issued) while preparing merger notification materials in parallel.

For purely domestic acquisitions, or deals involving only EU/EEA acquirers where the target is not in a sensitive sector, the competition filing vs FDI clearance question resolves itself: only the merger control route applies (if turnover thresholds are met).

Dimension‑by‑Dimension Analysis: Merger Control vs FDI Screening France 2026

Eligibility and thresholds

The eligibility triggers for the two regimes are structurally different. Merger control thresholds are purely quantitative (turnover) and apply irrespective of investor nationality. FDI thresholds are qualitative (investor nationality + sector sensitivity) overlaid with a quantitative control test.

• Merger control: notification is required when the parties’ combined worldwide turnover and their individual turnover in France each exceed the applicable national thresholds. If EU‑level thresholds under the EUMR are met, exclusive jurisdiction shifts to the European Commission.
• FDI screening: notification is required when a foreign investor acquires more than 25 % of voting rights (non‑EU/EEA investor) or control (EU/EEA investor) in a French entity active in a listed sensitive sector.

Cost and fees

Neither the Autorité de la concurrence nor the Direction générale du Trésor charges a statutory government filing fee. The real cost of either process lies in professional advisory fees and, where remedies are required, compliance implementation.

Timing and process

Notification timing differs in predictability. Competition reviews follow published procedural clocks; FDI reviews are more discretionary.

• Merger control: pre‑notification contacts (days to weeks) → formal Phase I (~25 working days) → Phase II if needed (several additional months). Total elapsed time for a straightforward Phase I clearance can be as short as six to eight weeks from first contact.
• FDI screening: pre‑filing meeting with the Direction générale du Trésor (recommended) → formal application → review period (weeks to several months depending on sensitivity) → possible commitment negotiations. Complex security reviews have no rigid statutory clock and may extend unpredictably.
• When both apply: begin MoE engagement at or before signing; file competition notification once the signed agreement is available and market data is complete. Run both tracks in parallel rather than sequentially.

Liability and sanctions

Both regimes impose serious consequences for non‑compliance, but the FDI regime carries the additional risk of criminal exposure in narrow cases. Closing before obtaining merger clearance (gun‑jumping) can result in administrative fines from the Autorité de la concurrence. Completing an investment without required FDI prior authorisation exposes the investor to forced divestment at the MoE’s direction, nullification of voting rights, and administrative penalties. The MoE has publicly signalled increased enforcement willingness in recent years, and early indications suggest the frequency of post‑closing review orders is rising.

Enforceability and remedies

Competition remedies are designed to restore competitive conditions: divestitures of overlapping business units, behavioural commitments (access, licensing), or structural reorganisations. FDI conditional authorisations are designed to protect sovereignty: governance ring‑fencing (independent French board members with security clearance), restrictions on transferring technology outside France, continuity‑of‑supply obligations, and reporting duties. FDI remedies are enforceable directly by the MoE and can include appointment of a compliance trustee. Breach of FDI conditions can trigger revocation of the authorisation itself, an outcome with no close parallel in merger control.

What Changed in 2026: FDI Screening Sectors and EU‑Level Reform

Three developments make the merger control vs FDI screening France 2026 analysis more complex than in prior years.

Expanded sector focus. French FDI screening continues to sharpen its focus on medical and biotech activities, AI and data‑sensitive technology, and semiconductor supply chains. The Direction générale du Trésor’s published guidance confirms that investments in these areas attract heightened scrutiny, and recent conditional‑authorisation decisions signal that the MoE is actively using its powers, not merely holding them in reserve.

EU‑level coordination intensifies. The European Parliament’s Committee on International Trade (INTA) adopted its position on the revision of the EU FDI Screening Regulation in February 2026, advancing proposals that would increase mandatory coordination between Member States on cross‑border FDI reviews. The likely practical effect will be longer review periods for transactions that touch multiple EU jurisdictions, as national authorities exchange information and opinions through a formalised cooperation mechanism. For deal teams, this means that an FDI filing in France may trigger parallel consultations, and potential objections, from other Member States.

FDI filings outpacing merger notifications. Industry observers note that FDI filings across Europe are now outpacing traditional merger control notifications in volume, reflecting both the broadened scope of screening regimes and the increasing proportion of cross‑border deals that involve sensitive technologies. France is at the leading edge of this trend. Transactions that five years ago required only a competition filing now routinely require an FDI filing as well, or instead.

The practical takeaway: any deal involving a non‑EU acquirer and a French target with activities in defence, health, biotech, AI, semiconductors, energy, telecoms, cybersecurity, data hosting, or critical infrastructure should be assumed to trigger FDI screening until a formal analysis confirms otherwise.

Decision Framework: When to Choose Merger Control Filing, When to Choose FDI Screening

Many transactions will require both filings. But where deal teams must prioritise resources, sequencing, and counsel selection, the following framework applies.

Choose merger control filing when:

• Turnover thresholds are met and the core regulatory risk is competitive harm, the buyer expects remedies limited to competition law (divestments, access commitments).
• The acquirer is EU/EEA‑based and the target does not operate in a listed sensitive sector.
• The deal has no foreign‑investment dimension (domestic‑to‑domestic transaction above thresholds).

Choose FDI prior authorisation when:

• The investor is non‑EU/EEA and the target operates in any FDI screening sector France 2026 (defence, health/biotech, AI, semiconductors, energy, telecoms, critical infrastructure, cybersecurity, media, food security).
• The investor is state‑owned or state‑linked, regardless of sector, MoE will scrutinise governance independence.
• The investment reaches the 25 % voting‑rights threshold for non‑EU/EEA investors or confers control for EU/EEA investors in a sensitive sector.
• The deal involves transfer of critical technology, access to classified data, or disruption risk to essential supply chains.

Choose both, and coordinate, when: the transaction meets merger filing thresholds and involves a foreign acquirer targeting a sensitive‑sector French entity. Run both tracks in parallel. Engage the MoE at or before signing; file competition notification as soon as the signed transaction documents and market data are available.

When (and Why) to Engage a Lawyer for Merger Control or FDI Screening in France

The decision to retain a Cross‑Border M&A lawyer in France should be triggered by specific deal milestones, not left to closing preparation.

• Pre‑LOI (letter of intent): engage counsel if the target operates in a sensitive sector or if the acquirer is non‑EU/EEA. A pre‑filing meeting with the MoE can be arranged before any binding commitment is made.
• Pre‑signing: engage counsel if turnover thresholds may be met or if the investor is state‑owned/state‑linked. Counsel should deliver a screening memo confirming which filings are required, estimated timelines, and advisory costs.
• Immediately upon signing: engage counsel (if not already retained) when thresholds are clearly met, standstill obligations apply and the filing clock begins.
• Before closing: counsel must confirm that all required clearances have been obtained and that any conditions or commitments are implementable at Day 1.

What counsel will deliver:

• Pre‑filing screening memo (filing obligation analysis, timeline, and cost estimate).
• Draft notification / authorisation application and supporting documents.
• Attendance at pre‑filing meetings with the Autorité de la concurrence and/or Direction générale du Trésor.
• Negotiation of remedies or conditional‑authorisation commitments.
• Closing‑readiness confirmation and Day‑1 compliance plan.

Practical fee arrangements commonly include a fixed fee for the initial screening memo, hourly rates for the filing process, and capped fees for predictable Phase I merger clearances. For FDI matters involving commitment negotiations, a blended hourly arrangement with milestone billing is standard.
