Rheinmetall Faces Twin Pressures: Market Selloff and Antitrust Alarm Over 'System Dependency'

Germany's Monopolkommission warns of systemic reliance on Rheinmetall, as shares slide 30% in a year despite 8% revenue growth and a push into satellite tech.

Germany’s antitrust watchdog has thrown a fresh spotlight on Rheinmetall just as the defence group’s shares languish near 12-month lows. The Monopolkommission warned on Tuesday that the country’s military procurement is becoming dangerously dependent on a handful of dominant players, singling out the Düsseldorf-based contractor for what it called a “Systemabhängigkeit” – a systemic reliance that stifles competition and inflates costs.

The warning adds a regulatory dimension to the headwinds already battering Rheinmetall’s stock. Shares slipped another 0.2% on Tuesday to €1,166.20, extending a slide that has wiped 27% off the value since the start of the year. Over the past twelve months the loss deepens to 30.6%, leaving the stock 41% below the September 2025 peak of €1,995. The 52-week trough of €1,099.80, struck recently, sits just 6% below current levels – a slender cushion that leaves little room for error.

Commission chairman Tomaso Duso argued that the concentration of Bundeswehr spending among a few large groups undercuts market forces. “Rüstungsgüter könnten dadurch zu teuer eingekauft werden,” Duso said, echoing concerns previously raised by the Bundesrechnungshof, which has criticised cost overruns and a lack of competitive bidding in major projects. Commission member Rupprecht Podszun went further, warning explicitly of a “system dependence” on Rheinmetall.

Yet the operational picture tells a different story from the market’s gloom. In the first quarter of 2026, Rheinmetall grew revenue by 8% to just under €1.94bn, while operating profit climbed from €191m to €224m. Management reaffirmed its full-year guidance of sales between €14.0bn and €14.5bn and an operating margin of around 19%, which would represent a massive leap from the €9.9bn recorded in 2025.

The technical charts, however, remain hostile. The stock is trading roughly 8% below its 50-day moving average and almost 26% below the 200-day line, with analysts describing a downward channel that has been in place since January. The selloff has been aggravated by peace hopes in the Middle East, which weighed on defence names across the board on Monday, hitting Rheinmetall, Hensoldt, Renk and TKMS alike.

Meanwhile, the company is pushing ahead with diversification to reduce its exposure to purely ground-based weaponry. A new joint venture with Finland’s ICEYE will develop satellite-based reconnaissance systems, while a partnership with VR specialist Varjo aims to digitise training in driving simulators. Finland is backing such dual-use technologies with €120m in funding. These moves point to a strategic shift from a pure hardware maker to an integrated technology provider.

The immediate market focus, however, is on the Baader Bank Partner Summit on 25 June, where Rheinmetall’s management may offer fresh colour on execution of the order backlog. With the stock trading just a few percentage points above its nadir, the next catalyst could come from either side – a political surprise, a contract win, or further regulatory scrutiny in Berlin.
