Europe is in the early innings of its most significant defense spending cycle since the Cold War. The geopolitical catalyst is clear: Russia's invasion of Ukraine in 2022 fundamentally altered European security assumptions. But the investment thesis rests on something more durable than crisis response — a structural reorientation of fiscal priorities.
European defense spending as a share of GDP has been declining for three decades. The reversal now underway is not a one-year blip — it's a multi-decade commitment that will reshape the European industrial landscape.
The Spending Trajectory
NATO's 2% of GDP defense spending target, once aspirational, is now becoming a floor rather than a ceiling. At the June 2025 NATO summit, members committed to "at least 2.5%" as the new benchmark. For context, most European nations spent 1.0-1.5% of GDP on defense as recently as 2020.
EU defense spending
$B, 2020-2026EThe math is staggering. Europe's combined GDP exceeds $18 trillion. Moving from an average of 1.5% to 2.5% of GDP implies over $180 billion in incremental annual defense spending — a figure that rivals the entire US defense procurement budget.
The Key Beneficiaries
European defense is a concentrated industry. Five companies capture the majority of European military procurement: Rheinmetall (Germany), BAE Systems (UK), Leonardo (Italy), Thales (France), and Saab (Sweden). Airbus provides a sixth pillar through its defense and space division.

Rheinmetall order backlog
€BThe order books tell the story. Rheinmetall's backlog has doubled in two years. BAE Systems recently reported its largest-ever order intake. These aren't speculative projections — they're signed contracts with sovereign counterparties.
The Munitions Gap
Perhaps the most acute shortage is in ammunition and munitions. European stockpiles were drawn down to dangerously low levels through decades of underinvestment. The EU's ambitious target of producing 2 million 155mm artillery shells per year by 2025 — up from approximately 300,000 in 2022 — illustrates the scale of the ramp required.
Munitions production capacity takes 2-4 years to build. Near-term shortages may persist even with full fiscal commitment. Companies with existing production infrastructure have a significant first-mover advantage.
Valuation Context
Despite the rally, European defense names trade at meaningful discounts to US peers on most metrics. Rheinmetall at ~39x EV/EBITDA reflects high expectations but is supported by the backlog; BAE Systems at ~14x is more modestly valued relative to its growth trajectory.
Risk Factors
The primary risk is political. Defense spending depends on sustained political will, which can shift with election cycles. A negotiated resolution to the Ukraine conflict could reduce urgency, though NATO structural commitments would likely persist. Currency risk also matters for non-EUR investors — many European defense names report in euros.
Investment Implications
This is a generational spending cycle with 5-10+ years of visibility. The order books provide unusual earnings certainty for an industrial sector. For investors seeking exposure, the European defense thesis offers a rare combination: structural demand growth, high barriers to entry, sovereign-backed revenue, and valuations that — despite the rally — still reflect meaningful upside if spending targets are met.
