European vs US Defense Stocks: EU Rearmament Versus the US Baseline

The Valuation and Growth Divergence

The headline numbers tell the story. Rheinmetall, the clearest beneficiary of EU rearmament, reached a market capitalization of roughly €75 billion by early 2026, having multiplied several times over from its pre-invasion value. Lockheed Martin, the largest pure-play US prime, moved from around $100 billion in early 2022 to about $125 billion in 2026 – a respectable gain, but a fraction of the European re-rating in percentage terms.

That contrast repeats across the two groups. European primes saw their valuations expand on the back of structural-growth expectations, while US contractors, already trading as large, defensive dividend payers, saw far more modest multiple expansion. The divergence was driven not by sentiment alone but by genuinely different growth trajectories, as the comparison below makes explicit.

Crucially, absolute size still favours the United States. RTX alone was valued in the region of $200 billion or more in 2026 depending on the source, larger than any single European name. Europe won the percentage race; the US retained the scale. Understanding the comparison means holding both facts at once.

Side-by-Side Comparison

The table groups selected listed defense names by region, showing an approximate 2026 market cap and a qualitative description of how much each re-rated since the February 2022 invasion. All figures are rounded, currency is not normalized across regions, and some entries are deliberately qualitative where a precise multi-year comparison would be misleading.

Why the Gap Opened

The single biggest driver was the base effect. Going into 2022, Europe's defense industry had been managed for peacetime efficiency, not surge capacity. Order books were thin and valuations low, so when budgets turned – Germany's €100bn special fund, NATO members pushing past the 2% of GDP floor – the proportional change in expected revenue was vast. The US primes faced the same demand wave but from a much higher starting point, leaving far less room for explosive multiple expansion.

Budget cycles reinforced the divide. European rearmament was a sudden, structural break that re-set expectations almost overnight, whereas US defense demand flows through a slower, congressionally-set appropriations process that markets had long since priced. The shock content was simply higher in Europe.

Ammunition exposure was the third factor. Artillery dominated the war in Ukraine, consumption dwarfed peacetime output, and stockpiles emptied fast. European firms that make 155mm shells, propellant and explosives – Rheinmetall above all – sat at the most valuable point in the supply chain, while US primes are weighted more toward platforms and electronics. Reuters-style reporting found combined annual revenue for Rheinmetall, Leonardo, BAE, Thales, Hensoldt and Saab rose roughly 57% on average between 2021 and 2025, with Leonardo more than doubling and BAE advancing about 60%, even as US primes traded at relative discounts to their European peers.

Growth Versus Capital Return

The comparison is not simply Europe good, US bad. It is a genuine trade-off between two different investment profiles. European names delivered the growth: rapid revenue increases, expanding backlogs and valuations to match. But that growth came on elevated multiples that already price in years of continued expansion, raising the downside if order growth disappoints.

The US primes offered the opposite. Their share-price gains were modest, but they carry long records of rising dividends and large buybacks – the kind of steady capital return that European growth stocks did not provide. For an income-focused holder, Lockheed, RTX, General Dynamics and Northrop have historically been the more dependable cohort.

This is why a like-for-like ranking can mislead. A European name that tripled may now be riskier on a forward basis than a US prime that gained 25% but pays a reliable, growing dividend. The right answer depends entirely on whether an investor is buying growth or capital return – and this page takes no view on that choice.

Risks and 2026 Outlook

By 2026 the easiest gains were behind the European sector. Defense stocks consolidated after their multi-year run, with Rheinmetall, Saab and Renk easing back as investors questioned whether peak valuations could be justified on slowing order growth. At high multiples, even small disappointments on production ramps or budget timing can trigger sharp pullbacks – a risk that is structurally lower for the more modestly-valued US primes.

Looking ahead, two themes stand out. The first is European consolidation: merger and partnership activity is widely expected to feature in 2026 as the continent tries to turn a fragmented industry into something closer to scale. The second is relative steadiness on the US side, where diversified programs and established dividends should continue to dampen volatility.

The structural bull case – depleted NATO stockpiles, multi-year framework contracts and committed budgets – remains intact and supports both regions. But much of Europe's growth is already in the price, so the gap between the two cohorts is more likely to narrow than to widen further.
