Rheinmetall's Flurry of Global Moves — From AI Ethics to Artillery — Leaves Investors Cold

Rheinmetall achieves production milestones (1,000th cruise missile engine, new JVs) and advocates AI regulation, yet stock drops 25% YTD, nearly 40% off peak.

The contrast between what Rheinmetall is building and what investors are buying has rarely been starker. Over the past week, the German defence group announced a raft of operational milestones: the 1,000th engine for a new generation of cruise missiles, a reconnaissance venture combining satellites and drones, a glide bomb co-production deal with an American partner, and a chief executive who used the Eurosatory platform to call for global rules on AI in warfare. Meanwhile, the shares closed Friday at €1,200.20 — a 2.16% gain for the day, but still down roughly 25% since the start of the year and nearly 40% below the 52-week peak of €1,995.

Chief executive Armin Papperger is taking the long view. On the sidelines of the Paris defence exhibition, he drew a parallel between the regulation of artificial intelligence in weapons systems and the treaties that govern nuclear arms, insisting that humans must retain final authority over life-and-death decisions. That stance resonates with the growing weight of environmental, social and governance (ESG) criteria among institutional investors, even in the defence sector. At the same time, Papperger is pushing ahead with a geographic expansion into Asia. According to the Nikkei business daily, Rheinmetall plans to establish a joint venture in Japan to produce defence equipment, tapping into a regional arms build-up that offers new export opportunities beyond its legacy automotive-parts business.

The group also made concrete strides in industrial scale-up. The joint venture with Destinus, Rheinmetall Destinus Strike Systems, produced its 1,000th T150 turbojet engine, which powers the Ruta B1 and B2 cruise missiles. Destinus has set its sights on turning out several thousand missile systems annually and has already unveiled the more powerful T220 engine, designed to push the Ruta B3 to a range of up to 2,000 kilometres. For Rheinmetall, the partnership secures access to long-range precision strike weapons without reliance on non-European suppliers.

Additional agreements signed during Eurosatory cover the air and land domains. A memorandum of understanding with VANTOR calls for a joint venture to develop spatial reconnaissance capabilities, fusing satellite imagery, drone feeds and cartographic data into a military-grade 3D picture for German and European forces. In the artillery segment, Rheinmetall inked an MoU with General Atomics to co-produce the Vektrex 155mm glide bomb, which extends the reach of conventional howitzers by a factor of two to three while remaining compatible with NATO-standard systems. On the production line, Rheinmetall UK has introduced 3D printing for complex pipe components on the Challenger 3 programme, slashing design iteration lead times to a single day.

Yet the market remains unconvinced. The stock's technical picture underscores the disconnect. The relative strength index stands at 46.8, a neutral reading, but the price is trading 6.5% below its 50-day moving average and roughly 25% below the 200-day moving average, which currently sits at €1,584.94. Analysts at Berenberg have held their target at €1,750, implying a recovery of nearly 46% from Friday's close, but the share price has shown little appetite for such a rebound.

Investors are waiting for the letters of intent and memoranda to harden into revenue-generating contracts. The Japan factory, the reconnaissance joint venture and the glide bomb agreement are all promising building blocks, but none has yet delivered a binding order. Rheinmetall must now prove that its rapidly expanding portfolio of hardware and systems integration can translate into the kind of earnings momentum that would reverse the twelve-month downtrend. Until then, the gap between the company's operational tempo and its stock valuation is likely to persist.
