Rheinmetall's €270 Million Kassel Bet Arrives at an Awkward Moment for the Stock

Rheinmetall invests €270M in Kassel tank plant, but shares fall 34% YTD despite record orders and strong Q2 growth.

The defense contractor's plan to transform its Kassel site into what it calls the world's "most modern tank factory" comes with a hefty price tag — and a share price that keeps heading in the wrong direction.

Rheinmetall announced on August 27 that it would invest roughly €270 million to expand its central German operations, adding a drone-testing facility at Calden airport, a logistics hub, and new production lines. The company expects headcount at the site to swell from around 2,200 today to approximately 3,500, while annual revenue generated in Kassel is projected to climb from €1.5 billion to €5 billion by 2029. The logistics hub is slated to begin operations at the end of 2027.

The expansion is one of several capacity-boosting moves the group has made in response to sustained demand for military hardware. At the heart of the Kassel build-out lies the so-called Arminius project — a planned mega-order for Boxer wheeled vehicles for the German armed forces. Final negotiations on the package, which carries a total volume of roughly €25 billion for Rheinmetall and its partner KNDS Deutschland, were scheduled for the second week of September. Parliamentary approval in the Bundestag is penciled in for December 9, with a possible signing just days afterward.

Rheinmetall's share of the firm order would come to approximately €12.4 billion, supplemented by an advance payment exceeding €3 billion and a service contract worth around €2 billion to the group. Should future framework-agreement options materialize, the industry-wide volume could eventually surpass €75 billion.

Record Orders, Negative Cash Flow

The investment decision lands at a moment of sharp operational momentum but persistent stock-market weakness. Second-quarter revenue jumped 69 percent to €3.289 billion, while operating profit surged 115 percent to €562 million, translating into an operating margin of 17.1 percent. The order backlog hit a record €80.5 billion at the end of the second quarter.

Yet the group's free cash flow tells a less flattering story. The operating figure came in at minus €1.331 billion for the second quarter, and the first-half deficit widened to €1.616 billion — a consequence of heavy upfront spending tied to capacity expansion.

International developments continue to move in the company's favor. Rheinmetall's Canadian subsidiary received an order from the US Navy for replacement components, and American Rheinmetall delivered the first of eight Lynx XM30 prototypes to the US Army.

A Valuation Debate Intensifies

The stock, meanwhile, remains stuck in a downtrend. Shares recently traded at €1,023.40, having lost 11 percent over the past 30 days and 34 percent since the start of the year. The price sits 49 percent below its 52-week high of €2,007.00 reached in October, and remains well under the 200-day moving average of €1,394.54 — a signal that the medium-term trend is still pointing down.

The disconnect between record operational performance and a sliding share price has become the central puzzle for investors. Some analysts argue the equity is still expensive despite the pullback, pointing to a projected price-to-earnings ratio of roughly 32.5 for 2026. The stock has at times slipped below the psychologically significant €1,000 threshold, though it has since recovered to around €1,042. It currently trades about 5.1 percent beneath its 50-day average, underscoring the near-term weakness.

Setbacks Alongside Success

Not everything is going according to plan. The F126 frigate project was halted in June after Dutch partner Damen Schelde failed to meet its timeline and budget commitments. Costs had ballooned to nearly €13 billion, with €2.4 billion already spent. TKMS — in which Rheinmetall holds a stake — has proposed its MEKO A-200 frigate design as a replacement, albeit at higher unit costs of €1.6 billion per vessel versus roughly €1 billion previously. The fate of the Peene shipyard in Wolgast, which employs around 400 people and is owned by Rheinmetall, remains uncertain as the company evaluates alternatives.

The group's order book for fiscal 2025 stood at €63.8 billion — another record — with expectations of more than €100 billion in additional orders for Rheinmetall alone, plus over €25 billion at TKMS. That figure includes a €6.3 billion order for four MEKO A-200 frigates for Germany. Revenue for 2025 rose 29 percent to €9.9 billion, operating profit advanced 33 percent to €1.8 billion, and net income came in at €0.8 billion, up 3 percent. Management has guided for revenue growth of 40 to 45 percent in 2026.

On the transatlantic front, American Rheinmetall secured a contract from Kongsberg to manufacture components for MCT-30 turrets used in the ACV-30 vehicle of the US Marine Corps. The order is valued at roughly $710,000, with production in Michigan scheduled for delivery in 2026 and 2027. Separately, Rheinmetall Canada is supplying spare parts for the MSU-200NAV to the US Navy, a contract worth a low-single-digit million euro amount running through 2028.

The Raw Material Question

The defense boom has also drawn attention to critical materials. Niobium — a metal whose production is heavily concentrated in Brazil — is emerging as a potential bottleneck for the broader arms industry. Rheinmetall does not yet face an acute operational challenge from this dependency, but the discussion highlights how tightly supply chains and geopolitical exposure are woven into the sector's growth trajectory.

For now, investors must weigh record order books and double-digit growth against valuation concerns and project-specific stumbles. The outcome of the Arminius negotiations in the coming weeks may determine whether the gap between Rheinmetall's operational strength and its share price finally begins to close — or whether the €1,000 mark becomes a floor rather than a ceiling.
