The boom in military spending in Europe has elevated defense companies to levels where their market capitalization is comparable to the largest luxury goods manufacturers. Historically, the defense sector was considered low-margin, but it has now become an area with high growth potential, and investors are buying shares faster than analysts can adjust target prices.
According to data from Goldman Sachs, cited by Bloomberg, the forward valuation of a basket of European defense stocks has surged in recent weeks, reaching the average P/E of European luxury manufacturers. Shares of German tank and ammunition manufacturer Rheinmetall have nearly doubled since the beginning of 2025. This has led to a record increase in the company’s projected valuation, which now sits between luxury market leader LVMH and Hermès, the maker of iconic Birkin bags, Bloomberg reports.
This surge has also impacted other European weapon manufacturers, including Thales and Leonardo. The optimism of stock market investors is based on promises from the German government for investments of hundreds of billions of euros in defense, as well as the desire of European authorities to follow suit. On March 11, shares of Rheinmetall jumped another four percent after the German Green Party expressed readiness to reach an agreement with the government to increase defense spending as early as this week.
Profitability of Investment in the Defense Sector
– The growth prospects for these [defense] companies today are completely different than they were six months ago. They may seem expensive right now, but that is only because the market and Wall Street have not yet caught up to raise earnings forecasts – said Graham Benke, fund manager at Amati Global Investors, to Bloomberg.
The market is debating whether double-digit earnings growth can be expected in this sector, said Robert Lancastle from J O Hambro, whose fund holds shares in Thales, Leonardo, and Saab.
– If double-digit growth is realistic – and we do not think it is impossible – then, for example, shares of Thales do not look overpriced – added Lancastle.
Some analysts believe that valuations are already excessively inflated, especially since Rheinmetall’s shares have risen more than 10 times since February 2022. Christian Kers from Warburg Research last week downgraded his recommendation for Rheinmetall from ‘buy’ to ‘hold’, noting that the current stock value is already supported by the projected increase in military spending to three percent of GDP.
