Why European Defense Stocks May Be the Trade of the Decade

The Iran war has fundamentally altered the European defense landscape. For decades, European governments systematically underfunded their militaries, relying on American security guarantees and the assumption that large-scale conflict in the modern era was a relic of the past. That assumption died on February 28, 2026.

Within weeks of the outbreak of hostilities, European nations announced a wave of defense spending increases that collectively represent the largest peacetime military buildup in the continent’s post-war history. Germany’s Zeitenwende, initially announced in 2022 after Russia’s invasion of Ukraine, has now been dramatically expanded. France, the UK, Poland, and the Nordic countries have all committed to sustained increases in military budgets.

For investors, this creates a rare and potentially transformational opportunity. European defense stocks — companies like Rheinmetall, BAE Systems, Thales, Leonardo, and Saab — are entering what may become a decade-long supercycle of revenue growth driven by government spending commitments that are politically irreversible.

The Defense Spending Wave: Quantifying the Opportunity

NATO defense spending commitments have reached unprecedented levels. The alliance’s target of 2% of GDP, long treated as aspirational, is now a floor rather than a ceiling. Several member states have announced targets of 2.5% to 3%.

To understand the magnitude of this shift, consider the numbers. Germany’s defense budget was approximately €50 billion in 2025. Under the expanded Zeitenwende framework, this is projected to reach €80–90 billion by 2028. France has committed to €413 billion over the 2024–2030 period. The UK has pledged 2.5% of GDP by 2030. Poland already spends over 4% of GDP on defense and continues to accelerate procurement.

Collectively, European NATO members are adding approximately €100–150 billion in annual defense spending over the next 3–5 years. This is not cyclical spending — it is structural, backed by multi-year legislative commitments.

Company Analysis: The European Defense Ecosystem

The European defense sector is concentrated among a handful of prime contractors, each with distinct competitive advantages and exposure to the spending wave.

Rheinmetall (RHM.DE) — The Ammunition Champion

Rheinmetall has emerged as the single largest beneficiary of European rearmament. The company’s ammunition business is experiencing demand that exceeds production capacity by a factor of 3–4x. Order backlogs have reached record levels, with the company signing framework agreements worth tens of billions of euros.

The investment thesis for Rheinmetall rests on three pillars: the acute and largely unfulfilled demand for artillery ammunition across NATO countries; the company’s expanding vehicle business anchored by the Panther KF51 main battle tank and the Lynx infantry fighting vehicle; and the company’s growing digital defense capabilities, including air defense systems.

Valuation: At current levels, Rheinmetall trades at approximately 25x forward earnings — elevated by historical standards for defense stocks, but potentially justified by a revenue growth trajectory expected to exceed 20% annually through 2028.

BAE Systems (BA.L) — The Transatlantic Bridge

BAE Systems is unique among European defense companies in that it derives approximately 45% of its revenue from the United States, giving it exposure to both European rearmament and US defense spending. The company’s submarine business — the Dreadnought and AUKUS programs — provides decades of visible revenue.

The AUKUS agreement, under which Australia will acquire nuclear-powered submarines based on BAE’s Astute-class design, represents one of the largest defense contracts in history, with lifetime revenues potentially exceeding $100 billion across the partnership.

Valuation: BAE trades at approximately 19x forward earnings, a modest premium to its historical average, with a dividend yield of approximately 2.5%.

Thales (HO.PA) — The Electronics Specialist

Thales occupies a critical niche in defense electronics, avionics, and cybersecurity. The company’s defense segment has seen order intake surge as European militaries modernize their communications, radar, and electronic warfare capabilities. Thales is also a key supplier to the French nuclear deterrent program.

Leonardo (LDO.MI) — The Italian Champion

Leonardo is Italy’s national defense champion and a significant player in helicopters, electronics, and space. The company has been restructuring under CEO Roberto Cingolani, with improved margins and growing international sales.

Saab (SAAB-B.ST) — The Gripen Maker

Saab benefits from the accelerated adoption of its Gripen fighter by smaller NATO nations and non-aligned countries. The company’s submarine business (the A26 class) and its Carl-Gustaf weapon system provide additional growth vectors.

Valuation Framework

When evaluating defense stocks in the current environment, traditional valuation metrics must be adjusted for the secular nature of the spending increase. A defense company with a €20 billion order backlog and 20%+ revenue growth visibility should not be valued on the same multiple as a cyclical industrial company.

Our framework considers: order backlog as a multiple of annual revenue (higher is better), revenue visibility (years of committed spending), margin expansion potential, and return on invested capital.

Risks

Defense stocks are not without risk. Potential headwinds include: peace negotiations that reduce the urgency of spending commitments (though the structural shift appears durable), execution risk on large programs, supply chain constraints for critical components, and political risk in countries where defense spending increases face public opposition.

Conclusion

European defense stocks represent one of the clearest secular growth opportunities in global equity markets today. The combination of structural spending increases, limited supplier competition, and multi-decade program visibility creates a favorable setup for patient investors.

The question is not whether European defense spending will increase — that is already committed. The question is whether current valuations adequately reflect the magnitude and duration of the spending wave. In our assessment, the market has begun to price the first phase of rearmament but has not yet fully priced the second and third phases.

This is a multi-year investment theme, not a trade. For investors with a 3–5 year horizon, European defense may indeed be the trade of the decade.
