Rheinmetall's Kassel Expansion and €100bn Backlog Ambition: A Defence Giant Caught Between Momentum and Market Doubt

Rheinmetall expands Kassel plant with €270M investment, backed by €12.4B Boxer order, but shares remain 41% below 52-week high.

The numbers keep getting bigger at Rheinmetall, yet the share price tells a more complicated story. On Thursday, the defence group's stock climbed 2.6 percent to €1,176.20, extending a recovery that has seen the shares gain 7.9 percent over the past month. The move followed confirmation of a €270 million investment in the company's Kassel plant — a facility that will become a cornerstone of German armoured vehicle production for decades to come.

The Kassel expansion is no minor upgrade. Rheinmetall plans to build a new drone testing centre, expand its tank production lines, and add a logistics hub spanning roughly 30,000 square metres. The state of Hesse is chipping in €25 million, with a further €8 million earmarked for a drone competence centre. When the facility comes online at the end of 2027, the workforce at the site is expected to grow from 2,200 to 3,500 employees — more than 1,000 new jobs in total.

The investment is anchored by the Bundeswehr's "Arminius" programme, a framework agreement covering up to 3,000 Boxer wheeled armoured vehicles with a total value of €12.4 billion. Rheinmetall says the order pipeline keeps the Kassel plant occupied through 2040 — a level of visibility that is rare in the defence sector and one that management hopes will reassure investors amid ongoing political debates about European defence budgets.

The Kassel announcement lands at a moment when the company is also pressing its case with institutional investors. At the DZ Bank "Expert Day" in Bremen, Rheinmetall executives are expected to lay out their growth strategy, with market watchers anticipating that the group will report an order backlog exceeding €100 billion by the end of fiscal 2026.

That projection is supported by a steady drumbeat of contract wins. Earlier this week, the Bundeswehr procurement agency BAIUDBw placed the first order under a framework agreement for a modular camp for 2,000 soldiers in Lithuania — €250 million for construction and setup, plus roughly €40 million per year for ongoing operations. Mid-August brought a follow-on order for mobile medical stations worth more than €500 million.

The company is also broadening its technological footprint. Together with Hensoldt, Rheinmetall recently demonstrated the integration of passive sensor technology into a modern air defence system. In Britain, the group has opened a competence centre for autonomous systems aimed at deepening collaboration with Canada.

Yet for all the operational momentum, the equity market remains cautious. The stock is still trading 41 percent below its 52-week high of €2,007.00, set in early October. Year-to-date, Rheinmetall shares are down 24 percent, and the twelve-month decline stands at 28 percent. The recent bounce has lifted the price 5.7 percent above its 50-day moving average, suggesting short-term stabilisation after a period of technical weakness.

Analyst sentiment reflects the mixed picture. Jefferies' Chloe Lemarie raised her price target from €1,300 to €1,350 in mid-August while maintaining a buy rating following the second-quarter results. JPMorgan's David Perry, by contrast, stayed at "neutral" with a €1,350 target, citing uncertainty around revenue forecasts for 2027 through 2030 despite strong quarterly numbers.

The Bremen presentation should give investors a clearer sense of how durable the growth story is beyond individual contract announcements. A further opportunity for Rheinmetall to make its case comes on 1 September at the Berenberg Stockholm Seminar. The widening gap between the order book and the share price suggests the market has yet to fully price in the group's long-term prospects — though the Kassel investment, with its decade-and-a-half visibility, may help close that divide.
