The Europe defence boom is not in doubt. EU spending reached €418bn in 2025, up 20 per cent on the year, and the European Defence Agency projects €454bn for 2026. Furthermore, 23 of the 27 member states now spend at least 2 per cent of GDP on their armed forces.
And yet Rheinmetall, Germany’s largest defence company, closed August around €1,135 roughly 43 per cent below its 52-week high of €2,008.
Meanwhile BAE Systems is down 10 per cent over six months and Leonardo 13 per cent.
That divergence is not evidence the thesis was wrong. Rather, it is evidence the thesis was bought.
Europe defence stocks already priced it in
Rheinmetall rose close to 200 per cent in the twelve months into 2025, and some European defence names gained well in excess of 1,000 per cent over five years. As a result, by March the sector traded on valuations richer than technology.
The businesses themselves have not disappointed. Rheinmetall’s second-quarter sales rose 69 per cent, operating profit more than doubled, and the order backlog passed €80bn against 2025 sales of €9.9bn. In other words, roughly eight years of work is already booked.
So the fundamentals accelerated while the equity halved. The market has not lost faith in the demand. Instead, it has simply stopped paying for that demand in advance.
Why Europe defence output lags the budget
A backlog is a promise. Revenue is a delivery. Critically, the distance between them is physical rather than financial.
Converting €80bn of orders requires explosives capacity, forging capacity and skilled labour welders, machinists, systems engineers on a continent that spent three decades closing exactly those facilities. Moreover, new munitions lines take years to permit, build and certify, because propellant plants cannot be commissioned quickly for safety reasons. None of that responds to a fiscal announcement.
Consequently, the question is no longer whether governments will spend. It is which companies convert, at what margin, and when. For investors, that shifts the work from picking a theme to picking a manufacturer.
The risk that actually materialised
The stress test everyone writes about is a ceasefire. However, the one that actually hit was smaller and stranger.
In June, Berlin abandoned the F126 frigate programme a €12.8bn contract Rheinmetall had been set to lead, having just bought a shipyard for €1.5bn to support it. The shares fell more than 13 per cent in a day, dragging Hensoldt, Indra, BAE, Thales, Saab and Leonardo down 1 to 5 per cent.
Yet no budget was cut. Germany still intends to buy warships eight smaller ones instead. TKMS, already contracted for four of them, rose more than 9 per cent the same morning.
The money did not leave the system. It moved between suppliers overnight, on a ministerial decision. Therefore the real risk in Europe defence equities is not that spending stops. It is that a state customer reallocates that spending faster than any commercial buyer could, with no warning and no recourse.
What Europe defence investors should watch
Three things now matter more than the headline budget number.
First, conversion. Watch the ratio of revenue growth to backlog growth, because a backlog that grows faster than sales is a capacity warning rather than good news.
Second, contract concentration. A company whose strategy depends on one national programme carries the F126 risk in concentrated form.
Third, entry price. Analysts have not capitulated 18 rate Rheinmetall a buy against one sell, with an average twelve-month target near €1,679 versus a share price around €1,135. Nevertheless, the sell side was also bullish at €2,000.
Europe will spend the money. That was always the easy call. Whether the spending buys capability, and whether capability pays the people financing it, are the questions the next three years will settle. In the end, the factories will answer them before the budgets do.
