Rheinmetall's Twinvis Breakthrough Can't Mask the Order-Book Questions That Have Investors on Edge

Rheinmetall's passive radar integration impresses operationally, but shares fall 24% YTD amid order backlog conversion and capex concerns.

The juxtaposition could hardly be starker. On Wednesday, Rheinmetall and Hensoldt demonstrated a genuine technological milestone in digital air defence, feeding passive radar data from Hensoldt's Twinvis system directly into Rheinmetall's command-and-control architecture during the "Timber Express 2026" exercise. The integration marks a meaningful step toward networked warfare, with passive sensors offering the obvious tactical advantage of remaining undetectable to enemy electronic surveillance.

The market's response? A 2.6 percent decline, closing the session at 1,180.00 euros.

That disconnect between operational achievement and share price performance has become something of a pattern for the Düsseldorf-based defence group. The stock now sits roughly 18 percent below its 200-day moving average and has surrendered 24 percent since the start of the year. The current price of 1,169.80 euros represents a 42 percent retreat from the 52-week high of 2,007.00 euros touched on 3 October.

The Order-Book Conundrum

The fundamental tension weighing on the shares is straightforward: Rheinmetall's backlog is enormous, but the market is increasingly questioning how quickly — and profitably — that pipeline converts into revenue.

At the end of the second quarter, the group's total order book stood at approximately 80.5 billion euros, a 44 percent increase year-on-year. The Vehicle Systems segment alone contributed 28.8 billion euros, up 41 percent. Those figures are undeniably impressive, yet JPMorgan analyst David Perry remains cautious, maintaining a "Neutral" rating with a price target of 1,350 euros while flagging growing uncertainty around backlog expectations and planned capital expenditure for 2027 and 2028.

It's a concern shared by others. mwb research downgraded Rheinmetall from "Hold" to "Sell" in early August, trimming its price target from 1,150 to 1,050 euros, citing an unfavourable risk-reward profile and criticism of a halved investment ratio of 8 to 9 percent alongside a reduced backlog target.

The sceptics have a point about timing. Even confirmed major projects take considerable time to reach the bottom line. The ATACMS production facility being established with Lockheed Martin at Unterluess, for instance, isn't expected to generate initial revenue until 2028. That lag between order intake and revenue recognition sits at the heart of the JPMorgan critique.

A Tale of Two Forecasts

The divergence among analysts is striking. Goldman Sachs reaffirmed its "Buy" rating and 2,300-euro price target in early August — implying roughly 93 percent upside at the then-price of 1,190.40 euros. That gap between the most bullish and most bearish houses underscores the genuine uncertainty surrounding the group's growth trajectory.

Some of that uncertainty stems from external factors beyond management's control. Rheinmetall was forced to revise its full-year revenue guidance down to 13.7 to 14.2 billion euros following the German defence ministry's cancellation of the F126 frigate programme. The first-half numbers themselves tell a story of robust operational momentum: revenue climbed 39 percent to 5.2 billion euros, while operating profit surged 74 percent to 786 million euros. Earnings per share from continuing operations more than doubled to 8.43 euros from 4.69 euros in the prior-year period.

Insider Activity Sends Mixed Signals

Adding another layer of complexity, insider transactions over the past 90 days paint a nuanced picture. Observers have tracked 15 insider sales totalling roughly 17.4 million euros — yet despite a 22.1 percent share price decline during the same period, five insiders, including senior executives, actually increased their holdings. That accumulation runs counter to the bearish stance adopted by JPMorgan and mwb research.

Strategic Ambitions Persist

Management, meanwhile, continues to pursue growth avenues beyond the current order book. CEO Armin Papperger has expressed ongoing interest in acquiring Iveco's military vehicle division from Leonardo, though any potential talks depend on incoming Leonardo chief Lorenzo Mariani. Media reports suggest a handshake agreement was already reached with his predecessor.

For now, the market's focus remains fixed on the near-term chart rather than the long-term narrative. The record backlog provides planning security for years to come, but with the stock trading well below its recent valuation levels, investors appear to be waiting for clearer evidence that the order pipeline can translate into earnings at the pace the share price once promised.
