Rheinmetall’s Market Cap Erodes as NATO’s Pillars Strengthen — The €993 Reality Check

Rheinmetall shares slump 38% in 2025 as investor scepticism over earnings conversion outweighs NATO’s 5% GDP target and Germany’s record €125bn defence spending.

The disconnect between order books and stock price at Rheinmetall has rarely been starker. Europe’s largest defence contractor closed last week at €993.00, slipping 1.90% on Friday and stretching its slide below the psychologically important €1,000 threshold. The decline is not a one-day anomaly: the shares have shed 9.48% in seven trading sessions, 16.96% over the past month, and 38% since the start of the year. Over 12 months the loss reaches 46.25%, leaving the stock at roughly half the 52-week high of €1,995.00 touched in September 2025.

The market’s scepticism is all the more striking because the strategic environment for Rheinmetall has rarely looked more favourable. At the NATO summit held in Ankara on 7–8 July, leaders agreed to raise the alliance’s investment target to 5% of GDP by 2035, a long-term commitment that directly benefits the group as a leading European systems integrator. Germany separately reported record defence spending of nearly €125 billion for 2026, equivalent to 2.69% of GDP. NATO Secretary-General Mark Rutte explicitly called for a stronger European defence industry, underlining Rheinmetall’s role as a key supplier of ammunition and armoured vehicles.

That promise of a multi-decade procurement pipeline was reinforced by concrete project announcements. Rheinmetall is planning Europe’s first production line for ATACMS precision munitions at its Unterlüß site, a joint venture with US partners designed to reduce European dependence on American supply chains. The group also sealed a low-double-digit-million-euro contract to equip eight Kuwaiti navy vessels with its MASS decoy launcher system, and together with MBDA Deutschland was awarded a mid-triple-digit-million-euro contract from the German procurement office to develop a naval laser weapon system by 2029.

Yet for all the headline-friendly news, the stock remains under intense pressure. Part of the explanation is the sector-wide rotation that has also hit peers Renk and Hensoldt — together the three German defence names have lost roughly €58 billion in market value. Analysts point to a growing gap between order backlogs and actual earnings conversion, a theme that has eroded investor confidence across the industry.

A concrete blow came from the German defence ministry, which axed the multi-billion-euro F126 frigate programme. Rheinmetall’s revenue exposure to that project is estimated at up to €300 million, a meaningful setback for its naval ambitions. Research houses were quick to trim their expectations: MWB Research slashed its price target from €1,400 to €1,150, while Jefferies — still sticking to a “Buy” rating and a €1,300 target — acknowledged a widening gap between near-term sentiment and the long-term growth story in munitions and defence electronics.

The chart continues to paint a bleak picture. Rheinmetall trades 34.59% below its 200-day moving average of €1,518.21 and 15.05% below the 50-day average of €1,168.88. The relative strength index at 37.2 suggests the stock is approaching oversold territory, but the annualised 30-day volatility of 68.77% underscores persistent nervousness. From the September 2025 record high, the stock has shed 50.23%, and the buffer to the 52-week low of €902.50 hit on 25 June is a mere 10.03%.

Adding to the competitive picture, Deutz AG announced on 9 July the acquisition of Flensburger Fahrzeugbau for €1.6 billion, creating a new heavyweight rival in the tracked armoured vehicle segment. That move introduces another variable for Rheinmetall as it navigates a shifting competitive landscape.

In the coming week, all eyes are on whether the €1,000 level can be reclaimed — a recovery that would signal a return of faith in the NATO-driven growth narrative. The next major catalyst arrives on 6 August, when Rheinmetall reports its second-quarter results. Until then, details on the Unterlüß capacity expansion and outcomes of international tenders are likely to drive the daily swings in a stock that remains both deeply oversold and fundamentally tied to the long-term rearmament of Europe.
