A world of opportunity - Foreign investment in Europe
The investment regimes in Europe are among the most open in the world. But a growing concern about the impact of foreign investment on security and public order has led to increased regulation.
This guide will help you navigate the foreign investment control regimes in the major European jurisdictions.

In recent years, there has been a proliferation of foreign direct investment (FDI ) regimes worldwide, including in the EU. It is therefore increasingly important to consider what FDI approvals may be required early on in any investment / M&A activity and to ensure that the deal timetable factors in the relevant review periods. Our team is very experienced in coordinating FDI filings alongside merger control and other filings.
In March 2019, the EU enacted the EU Screening Regulation, which provides for a cooperation mechanism for screening FDI in EU Member States. The Regulation came into effect on 11 October 2020 and it gives EU Member States and the European Commission the ability to exchange information, provide comments and issue opinions on FDI. However, EU Member States retain decision-making power in relation to FDI in their jurisdictions.
In 2024, the European Commission received 477 notifications from 18 EU Member States. In its fifth annual report (published in October 2025) the European Commission stated that 92% were assessed at Phase 1 (i.e. within 15 calendar days) and less than 2% of transactions resulted in a European Commission opinion (reserved for cases raising more complex issues).
In December 2025, the European Parliament, Commission and Council reached a provisional agreement on a new EU Foreign Investment Screening Regulation. The draft text was published in February 2026 and:
As of March 2026, 26 EU Member States have FDI screening mechanisms in place and Cyprus’ screening mechanism is due to enter into force on 2 April 2026. In addition to the jurisdictions covered in this note, the following countries have FDI regimes in place: Austria, Bulgaria, Croatia, Czech Republic, Denmark, Estonia, Finland, Greece, Hungary, Ireland, Latvia, Lithuania, Malta, the Netherlands, Poland, Portugal, Romania, Slovenia, the Slovak Republic and Sweden.
The Belgian Foreign Direct Investment screening regime entered into force on 1 July 2023. It regulates investments by non-EU investors in certain sectors in Belgium.
Investments in a Belgian entity active in:
(i) critical infrastructure for energy, transport, water, health, electronic communications, media, data processing or storage, air or space traffic, defence, financial infrastructure or infrastructure used for elections and sensitive installations; technologies and raw materials of essential importance to public health, defence, public security, public order; military equipment, dual-use products; supply of critical inputs; access to and ability to control sensitive information including personal data; private security; freedom and pluralism of the media and strategic technologies in the biotech sector; or
(ii) defence; energy; cyber security; electronic communications; and digital infrastructure.
Any investments by non-EU investors (ultimate beneficial owner) that result in:
Filing is mandatory and authorisation must be granted before the investment in the Belgian entity can be completed.
Verification Procedure: an initial review period of 30 calendar days applies; the clock will be stopped if the Interfederal Screening Committee (ISC) requests additional information.
Screening Procedure: if the transaction requires further investigation, there will be a further review period of at least 28 calendar days:
Whether the investment could have an impact on national security, public order, or the strategic interests of the Belgian federated entities, taking into account whether:
Fines of up to 30% of the investment value in relation to the Belgian entity for:
Where a previously unnotified investment is notified within 12 months of completion, the fine will be limited to 10% of the investment value.
Fines of up to 10% of the investment value for:
Generally, foreign investments in France only require declarations to be made to the Banque de France after completion. However, prior consent must be sought for investments in certain sensitive or strategic sectors.
Any activity relating to public order, public security, or national defence interests.
The French Monetary and Financial Code sets out a list of business sectors that are considered "strategic", which can broadly be split into three categories:
Filing is mandatory and authorisation must be granted before the investment can be completed.
30 business day screening period to assess whether the transaction is in scope or is authorised without conditions.
A further 45 business day period if a more in-depth review is needed, including if conditions need to be imposed.
Whether the investment affects French national interests. The authorisation can also be refused if French authorities consider that the investor:
For making an investment without required prior authorisation or non-compliance with conditions:
Germany has an established foreign direct investment review mechanism which allows the Federal Ministry of the Economy and Energy to review investments for national security concerns. Since the 20th Ordinance amending the German Foreign Trade and Payments Ordinance entered into force in 2023, all submissions must be made digitally.
Cross-sector review: transactions in any sector may be called in. However, 27 sectors have been specified as potentially giving rise to security concerns (including energy, IT, telecommunications, finance, transport, health, water supply and critical or emerging technology sectors such as AI, robotics etc.).
Sector-specific review: certain defence, certain export control-relevant, and IT security, companies (including manufacturers / developers of weapons and certain other military technology, operators of defence-relevant facilities, and companies with IT security features used for processing classified government information).
Cross-sector review: for acquisitions by non-EU / non-EFTA resident investors relating to the 27 specified activities, notification is mandatory.
The acquirer may also seek a certificate of non-objection for non-notifiable transactions. The Ministry can also initiate an ex officio investigation.
Sector-specific review: filing is mandatory for acquisitions by non-German investors.
Cross-sector review and sector-specific review: 2 months to initiate a review and, if a review is initiated, up to 4 months to review the proposed investment. In certain circumstances, the review period may be extended by up to 4 months.
Cross-sector review: whether the acquisition poses a threat to the public order or security of Germany, another EU Member State or certain projects of EU interest. Particular factors which may suggest a threat to public order or security include:
Sector-specific review: whether the acquisition poses a potential threat to the essential security interests of Germany.
Failure to comply with notification obligations, prohibitions or orders issued by the Ministry of Economy or with gun-jumping provisions may be sanctioned as a criminal offence, as well as incur administrative fines of up to €500,000.
A new Investment Screening Act is expected by mid-2026. The new Act is expected to apply to an expanded list of sectors and to introduce faster review timelines, new rules for greenfield and intellectual property transactions, a shift from residence-based to nationality-based assessment of foreign investors and broader exemptions for intragroup restructurings.
Italy has a sophisticated FDI regime in place that has been further strengthened in recent years to cover increasingly strategic sectors to protect Italy's national interests.
Any activity involving:
All sectors:
Defence and national security:
Other sectors:
5G communications sector:
Creation of a security interest over "strategic" assets:
Filing is mandatory and the Government has the power to intervene if no filing is made.
Pre-notification procedure: 30 days, after which the parties will be informed whether a notification is required.
Review period: up to 45 business days from filing (which may be extended to a maximum of 75 business days where further information is requested).
5G communications sector: review period of up to 30 business days for 5G networks, but this may be extended by 40 business days depending on the complexity of the case.
The Italian Government will assess whether the resulting situation entails a risk to Italy's essential interests, public order or public security, considering (i) the transaction structure; (ii) continuity of supply; (iii) the acquirer's activities; and (iv) the acquirer's links to states that do not recognise democracy or to criminal organisations.
For failing to notify a transaction, fines may be imposed amounting to:
A new screening regime for Foreign Direct Investment by non- EU / EEA investors into Luxembourg entered into force on 1 September 2023.
Investments in an entity active in a critical activity in Luxembourg, including activities in the following sectors: (i) energy, (ii) transport, (iii) water, (iv) healthcare, (v) telecommunications, (vi) airspace, (vii) defence, (viii) development exploitation and trade of dual-use goods, (ix) data processing or storage, (x) media and (xi) food safety (agribusiness) sectors, as well as certain key financial sector activities such as activities of the central bank or relating to Luxembourg's financial infrastructure (including payment and settlement systems).
In addition, critical activities includes (i) research and production activities directly in connection with a critical activity and (ii) related activities allowing access to sensitive information directly linked to a critical activity or likely to allow access to premises in which a critical activity is carried out.
Investments by non-EU / EEA investors that result in the acquisition of direct or indirect control of a Luxembourg entity operating in one of the affected sectors.
An investment results in the acquisition of control if the investor obtains:
Intra-group transactions are not excluded from the scope of the regime.
However, acquisitions of securities which do not grant the investor any direct or indirect control over the target and which are being made with the intention to effect a financial placement (portfolio investments) are explicitly excluded from the notification requirement.
Filing is mandatory and approval must be granted before the investment can be completed.
As an exception, the investor has a period of 15 calendar days to submit the notification in the event that it exceeds the threshold of 25% of voting rights in a Luxembourg entity following events that alter the allocation of the Luxembourg entity's share capital.
The notification will trigger a pre-assessment phase of up to 2 months during which the Ministry of Economy will decide whether to launch an in-depth screening procedure. The in-depth screening procedure may last up to 60 calendar days.
During the pre-assessment phase and the screening procedure, the foreign investor may continue to take preparatory steps with a view to finalising the investment at the investor's own risk. However, the investment must not be completed until the Ministry of Economy has issued a positive screening decision. Any requests from the Ministry for additional information will suspend the screening procedure until the relevant information is provided.
Whether the investment is likely to affect the security of or public order in Luxembourg in accordance with the following five factors:
Failing to notify a transaction or completing a transaction without approval may result in (i) the Ministry suspending the voting rights attached to the investment until the situation has been rectified, and (ii) an order requiring the investor to modify the terms of the investment or to unwind it entirely, at its own expense.
Failure to comply with specific orders and injunctions may result in fines.
The Spanish FDI regime entered into force on March 2020 and was further developed by Royal Decree 571/2023. Investors from the EU and EFTA are also subject to the new FDI regime until 31 December 2026.
Ex-post declarations: all sectors.
Prior authorisation: defence activities and following the entry into force of EU Regulation 452/2019:
Prior declaration: all sectors if the investor is from a country identified as a tax haven and the investment is 50% or more, unless the investment is made in a listed company or regulated fund.
Other sectors: there are additional regulations for acquisitions in the audio-visual, energy and air transport sectors.
Ex-post declarations are required for the following investments by foreign investors:
Investment in a listed company carrying out activities related to national defence will require authorisation where the investment represents more than 5% of the target's share capital or allows the investor to participate in the target's managing body.
Prior authorisation is required for:
Both declarations and prior authorisations (if required) are mandatory.
An investor may carry out an investment immediately after submitting a declaration, but must wait for prior authorisation where that is required.
It is possible to submit a consultation where there are reasonable doubts about whether the FDI regime applies to the investment.
Except for national defence, investments can be exempted where the turnover of the target is less than €5m (provided certain conditions are met). There are also certain exemptions for transactions relating to the energy sector.
No "one-stop shop": if a transaction relates to a strategic sector and national defence, both filings must be submitted and separate authorisations are required.
Maximum 3 month review period for authorisation but requests for information and negotiating commitments may stop the clock. If approval is not granted within the 3-month review period then the transaction is deemed to have been rejected.
For consultations, the maximum review period is 30 business days.
Assessments will generally be based on the Spanish public interest. Transactions will be assessed to determine whether they may jeopardise security, public order or public health in Spain.
The transaction is invalid and without legal effects, meaning that the economic and voting rights of the foreign investor are suspended until the required authorisation is obtained.
Failure to obtain authorisation prior to investment (where required) may result in a fine of between €30,000 and the total amount of the investment and a public or private warning.
The UK national security and investment regime entered into force on 4 January 2022. It applies equally to domestic and foreign investors.
Mandatory regime: the government has identified 17 key sectors as potentially raising particular national security concerns: advanced materials, advanced robotics, artificial intelligence, civil nuclear, communications, computing hardware, critical suppliers to Government, cryptographic authentication, data infrastructure, defence, energy, military and dual-use, quantum technologies, satellite and space technologies, suppliers to the emergency services, synthetic biology and transport. Specific activities in these sectors are subject to mandatory prior approval.
Voluntary regime: all other activities or sectors. Government guidance indicates a voluntary filing may be more advisable when the target carries on activities which are closely linked to specified activities in the key sectors.
The Secretary of State also has the power to call in transactions in any sector.
Mandatory regime: acquisitions of control over a qualifying entity which carries on specified activities within the 17 key sectors are subject to mandatory notification.
Control is generally defined as acquiring more than 25% of the shares / voting rights. Acquisitions which result in an investor holding more than 50% or at least 75% will be treated as new trigger events.
A qualifying entity:
However, in order to be subject to mandatory notification, the qualifying entity must generally carry on the relevant specified activities in the UK.
Voluntary regime: in addition to the trigger events applying to the mandatory regime, the acquisition of "material influence" is a trigger event for the voluntary regime.
Asset deals (including land and IP) may also be caught by the voluntary regime. Acquisition of a right or interest will be a trigger event if the person is able to: use the asset (to a greater extent than before); or direct / control how the asset is used (to a greater extent than before).
Transactions which fall within the mandatory notification regime must be notified and approved before completion.
Parties may choose to make a voluntary filing for transactions which do not fall within the mandatory regime. The Secretary of State has the power to call in a transaction for up to 5 years after the event, but this is reduced to 6 months from when the Secretary of State is made aware of the trigger event.
Initial 30 working day review period.
If the transaction is called in for a more detailed review, the Secretary of State has an additional period of 30 working days following the call-in notice, extendable by a further 45 working days. Further extensions may be agreed. Following a call-in notice, any information request stops the clock until the Government confirms it is satisfied with the response.
When deciding whether to issue a call-in notice, the Secretary of State expects to primarily consider whether:
If a transaction is called in, the Secretary of State will then determine whether it gives rise to a national security risk and if so, what remedies should be imposed (which may include prohibition, but lesser remedies are much more common).
If a transaction which falls within the mandatory regime is closed prior to approval, it will be void (but it will be retrospectively validated if a clearance is subsequently obtained). Other sanctions include:
The UK Government has announced proposed amendments to the UK regime, including proposals to update certain existing mandatory sector definitions (such as advanced materials, artificial intelligence, communications, critical suppliers to government, data infrastructure and energy), create standalone mandatory sectors for critical minerals and semiconductors and add a new mandatory sector (water). In addition, the Government has said in 2025 that it intended to carve out the appointment of liquidators, special administrators and official receivers, and certain internal reorganisations from the scope of the mandatory regime. However, as at 13 March 2026, no steps had been taken to bring this forward.
