Shares in Rheinmetall closed Friday at €1,200.20, a modest 2.16% gain that does little to change the broader picture: the stock sits almost 40% below its September 2025 record of €1,995 and just 9% above its 52-week trough of €1,099.80. That punishing decline has come even as the Düsseldorf-based defence group locks in a record order book and pushes deeper into new domains — land, sea, air and now advanced ammunition with an American partner.
At the Eurosatory trade show, Rheinmetall signed a memorandum of understanding with General Atomics to jointly produce Vektrex, a manoeuvrable 155-mm precision-guided artillery round that can be fired from existing howitzers without new launchers or extra logistics. Its aerodynamic design doubles or triples the range of standard munitions and it remains effective in GPS-denied environments. Yet the agreement remains a strategic framework, not a commercial contract: no factory sites, investment commitments or delivery dates have been disclosed, and the two companies are still evaluating cooperative production options. For now, there is no attributable revenue contribution.
The timing underscores the central tension hanging over Rheinmetall’s stock. Management has set a medium-term target of producing more than one million artillery shells annually, with capacity expected to rise further by the decade’s end. General Atomics brings scalable manufacturing expertise that could accelerate that effort. But the market has seen little concrete evidence that Rheinmetall can translate its bulging pipeline into margins fast enough to justify a valuation anywhere near its peaks.
Should investors sell immediately? Or is it worth buying Rheinmetall?
Technically, the shares remain under pressure. The stock trades roughly 6.5% below its 50-day moving average and more than 24% below its 200-day average of €1,585. The relative strength index sits at 46.8, a neutral reading, while the annualised 30-day volatility near 41% reflects how quickly the stock can whip around on geopolitical headlines — peace signals, German budget debates or NATO communiqués often move it more than quarterly earnings.
The coming days will test whether management can provide more clarity. On 23 June, Rheinmetall presents at the Mediobanca CEO Conference; two days later it appears at the Baader Bank Partner Summit. Executives may use those platforms to flesh out the Vektrex roadmap or update investors on the capacity ramp-up. For the moment, however, the pact with General Atomics remains a conceptual blueprint.
The next hard data point arrives on 6 August 2026, when the group releases its second-quarter report. Until then, the stock is hostage to the same macro and geopolitical crosscurrents that have erased nearly two-fifths of its value since last autumn. The structural tailwinds are unmistakable — European NATO spending is rising to Cold War levels, Germany is leading the charge, and Rheinmetall’s diversification into naval, drone and satellite systems is widening its addressable market. The open question is whether production can catch up with demand fast enough to convert that order book into the margins investors once priced in.
