Luxembourg Foreign Direct Investment : Key Developments and Practical Considerations for Investors in 2026
Luxembourg’s foreign direct investment (“FDI”) screening regime, introduced by the Law of 14 July 2023 and effective since 1 September 2023, has now entered a more mature and operational phase. Over the past two years, the Luxembourg Ministry of the Economy has gained practical experience handling notifications, particularly in transactions involving regulated sectors and strategic infrastructure.
The Luxembourg FDI framework applies to investments made by non-EU / non-EEA investors that may affect security or public order and that result in control over a Luxembourg entity carrying out critical activities, which are activities considered sensitive for national security or public order.
The FDI regime is applicable where a foreign investor acquires direct or indirect control, including majority voting rights; the ability to appoint or remove a majority of directors; or the crossing of a 25% voting rights threshold.
The FDI regime applies to sectors considered strategically sensitive and foreign investors must notify the Ministry of the Economy before completion of an in-scope transaction. The process generally consists in a preliminary assessment phase – the Ministry determines within approximately two months whether a formal screening is required; and the screening phase – if initiated, the review may last up to 60 calendar days, subject to extensions where additional information is requested.
Failure to notify may expose investors to significant consequences, including suspension of voting rights, unwinding measures, and administrative fines.
Recent market practice indicates a growing number of precautionary filings by investors and advisors, reflecting the broad interpretation of critical activities and increasing regulatory sensitivity around strategic assets.
Investors considering acquisitions, restructurings, or minority investments involving Luxembourg entities should conduct early-stage FDI screening assessments.
Given the increasing sophistication of Luxembourg’s screening practice and broader EU regulatory developments, FDI analysis is becoming an integral component of transaction due diligence and deal execution strategy.
