Rheinmetall's Order Book Is Bursting — Now the Hard Part Begins

Rheinmetall's Q2 profit nearly doubles, but negative free cash flow and order backlog conversion concerns temper share price gains.

The arithmetic at Rheinmetall is getting harder to argue with. The Düsseldorf-based defense group posted second-quarter operating profit of €562 million, nearly double the €276 million it earned in the same period a year earlier, while revenue jumped 70 percent to €3.3 billion. The operating margin of 17.1 percent blew past the 14.9 percent analysts had penciled in, and the order backlog has now crossed the €80 billion threshold for the first time.

Yet the share price response has been muted — a wobbly sideways drift rather than a celebration. The reason sits squarely in the cash flow statement.

The Cash Gap Nobody Is Ignoring

Rheinmetall reported a sharply negative operating free cash flow for the quarter, which management attributes to deferred customer prepayments and a deliberate build-up of inventories. That explanation is reasonable on its face — growing order books tie up working capital before converting into revenue and cash — but investors are withholding judgment until the full half-year report lands on August 6 and provides more granular detail.

The stakes are considerable. At a market capitalization of €53.83 billion, the market is paying a premium for Rheinmetall's growth story. Whether that premium holds depends on the company's ability to convert its record backlog into actual money — and to do so before potential budget cuts at the Bundeswehr start to bite. Media reports suggest Germany's ammunition budget could shrink from €11 billion to €9.6 billion in 2027, a scenario that would test whether the company's margin resilience is structural or cyclical.

Fresh Orders Keep the Pipeline Full

The order flow shows no signs of slowing. This Friday, Rheinmetall announced a new UK contract to supply weapon systems for 72 RCH 155 wheeled howitzers, an order in the low triple-digit million euro range that London had already placed in May. Production will take place in Telford, where the company has established a new gun manufacturing facility, with deliveries scheduled between 2028 and 2031. The RCH 155 itself comes from ARTEC GmbH, a joint venture between Rheinmetall and KNDS Deutschland.

The naval side is expanding too. Rheinmetall is modernizing the F123-class frigate Bayern at the Neue Jadewerft in Wilhelmshaven, a mid-triple-digit million euro contract awarded at the end of the second quarter. The work — covering the command system, radar, propulsion and anti-submarine warfare capabilities — is slated to run until 2029 and aims to keep the vessel operational until at least 2035, extending the service life of the Bundesmarine's aging F123 fleet.

In Romania, Rheinmetall is negotiating the acquisition of the Mangalia shipyard, a move tied to a €920 million order for four military vessels financed through the EU's SAFE program. The Romanian Senate approved the relevant SAFE contracts on Thursday, but creditors are still demanding €184 million for existing assets — an open point that could delay the deal's completion.

CEO Sees Another €80 Billion Coming

CEO Armin Papperger is looking well beyond the current backlog. He expects roughly €80 billion in additional orders in the coming years, driven by further purchases of the Leopard 2 tank, the GTK Boxer wheeled armored vehicle and the Puma infantry fighting vehicle. Germany alone, he estimates, offers potential of €30 billion to €35 billion. Cost reductions are expected to come from mass production and automation.

The ammunition ramp-up is particularly striking. Rheinmetall plans to increase 155mm ammunition production capacity from 70,000 units in 2022 to 1.1 million units by 2027 — a seven-fold expansion that underscores the company's strategic role in European defense supply chains.

The Share Price Has Recovered — But Only Partially

The stock has climbed 11.16 percent over the past seven trading days to €1,149.40, placing it slightly above its 50-day moving average of €1,109.36. That short-term momentum is encouraging, but the bigger picture remains sobering: the share still sits 42.73 percent below its 52-week high of €2,007.00, reached in October of last year.

The bull case rests on genuine operational strength — the €562 million operating result beat the €470 million consensus by a wide margin, suggesting fixed costs are being spread more efficiently as volumes scale. The €80 billion backlog extends well beyond 2027, and the naval contracts demonstrate diversification beyond ammunition and land systems. Even competitor Heckler & Koch reported a 47 percent revenue increase in the first half, signaling that NATO demand remains robust and could offset any German budget tightening through export growth.

The bear case is equally coherent. The long-term downtrend is not yet broken. If the ammunition budget does fall to €9.6 billion in 2027, that could mark the beginning of a broader consolidation in German defense spending — and Rheinmetall depends heavily on long-term framework contracts with the Bundeswehr. If the operating free cash flow remains negative into the third quarter, doubts about the quality of the record backlog will only grow. And technically, the stock's recent bounce could fade quickly given its elevated volatility.

August 6 will be the moment of truth. The half-year report needs to provide convincing answers on the cash flow gap and a credible plan for navigating the budget risks beyond 2027. If management delivers on the cash conversion front, the record margin could finally win back the market's confidence. If not, the stock may find itself heading back toward its yearly low — regardless of how full the order book looks.
