European Defense Spending Surge: The €800 Billion Rearmament Wave and M&A Implications
bIAnk AI Research · March 2026 · 8 min
Europe's commitment to rearmament is unleashing the largest defense spending increase since the Cold War. The ReArm Europe plan and national pledges create a massive M&A opportunity across defense, aerospace, and dual-use technology.
The geopolitical landscape has fundamentally shifted European defense priorities. The EU's ReArm Europe plan, announced in early 2025, mobilizes up to €800 billion in additional defense spending through a combination of EU-level borrowing, relaxed fiscal rules, and national budget increases. Germany alone has created a €500 billion infrastructure and defense special fund, while France, Italy, and Poland are increasing defense budgets to 3-3.5% of GDP.
This unprecedented fiscal commitment is creating a defense M&A supercycle. According to Roland Berger, European defense sector deal volume increased 85% in 2025, with transaction values exceeding €45 billion. The pipeline for 2026 is even larger, with multiple cross-border consolidation plays underway.
Key subsectors attracting investment include missile and ammunition manufacturing (capacity must triple to meet NATO standards), cybersecurity and electronic warfare, autonomous systems and drones, and space surveillance. Mid-market defense companies with specialized capabilities are being acquired at 15-20x EBITDA multiples, compared to historical averages of 10-12x.
The dual-use technology space is particularly active. Companies developing AI-enabled surveillance, quantum computing encryption, and advanced materials are drawing interest from both traditional defense primes and private equity sponsors. Palantir, Anduril, and their European equivalents are setting the template for tech-defense convergence M&A.
For dealmakers, defense M&A presents unique regulatory considerations. National security reviews, ITAR/EAR compliance, foreign ownership restrictions, and classified program access requirements add complexity and extended timelines. However, the scale of the opportunity—estimated at €200+ billion in addressable M&A over the next five years—makes defense one of the most compelling sector themes in European capital markets.
