The global defence sector is undergoing its most significant structural transformation in a generation. Escalating geopolitical tensions, the industrialisation of drone and autonomous systems, and the integration of Artificial Intelligence into military capabilities are reshaping the competitive landscape, the regulatory environment and M&A activity across the sector.
Key takeaways:
Technology and the changing character of defence
The boundary between defence and non-defence businesses is increasingly blurred. Early specialist legal advice on classification is no longer a precaution; it's a deal necessity.
A changing competitive landscape
Expect a wider and faster-moving market, with more buyers, more capital and more competition for assets.
Governmental intervention
Expect sustained and significant government demand across the globe, creating real commercial opportunity.
Navigating the European M&A regulatory landscape for M&A and JVs Merger control
Defence deals may benefit from greater scope for clearance, but the potential use of specific EU law rules for defence M&A, such as Article 346 TFEU (protection of essential security interests) and national merger review call-in powers (allowing authorities to review transactions which fall below the normal filing thresholds), require early strategic planning.
FDI and national security screening review
Early and detailed diligence is essential to map possible FDI and national security screening reviews and assess any related execution risks.
State aid and subsidy control
Consider the application of the Foreign Subsidies Regulation at an early stage.
Public procurement rules
Verify procurement compliance early, as contracts awarded in breach of the rules are vulnerable to challenge and annulment by unsuccessful bidders.
General competition rules
Consideration of general competition law rules must be built into deal and JV planning and execution from the outset.
