Triple-Layer Foreign Investment Compliance for Defence M&A
How the EU’s foreign subsidies, FDI screening and outbound investment architecture is reshaping cross-border defence transactions.
European defence M&A is no longer governed by a single regulatory question. A cross-border transaction involving defence, dual-use, cyber, space, AI, quantum, semiconductors or critical infrastructure may now trigger several distinct forms of state review at the same time. The Foreign Subsidies Regulation examines whether non-EU financial support distorts the internal market; the EU FDI framework and national screening regimes assess risks to security and public order; and the emerging outbound investment monitoring framework introduces a further layer around technology leakage, know-how transfer and strategic dependency. The result is a new transaction environment in which capital origin, governance rights, access to sensitive data, technology transfer and public-sector financing can matter as much as price, industrial fit or antitrust clearance.
The report is structured around the three principal layers of this new compliance architecture. It first analyses the Foreign Subsidies Regulation as a Commission-led tool for scrutinising foreign financial contributions in mergers, acquisitions and public procurement. It then examines the reform of the EU FDI Screening Regulation and the continuing divergence of national regimes in Italy, France, Germany, the Netherlands, Spain and Poland. A separate section addresses Recommendation (EU) 2025/63 on outbound investment monitoring, before comparing the European model with U.S., Japanese and South Korean approaches. The final sections translate the regulatory framework into transaction practice, assessing implications for deal timing, due diligence, sovereign wealth funds, private equity, venture capital, law firms, M&A advisers and the future of European defence-industrial consolidation.
