Rheinmetall’s Cash Flow Squeeze Overshadows €73 Billion Order Backlog as Stock Nears Low

Rheinmetall shares near 52-week low after Q1 earnings miss and negative free cash flow from inventory buildup. Analysts divided on outlook as record order book and naval expansion offer long-term growth potential.

The disconnect between Rheinmetall's bulging order book and its flailing share price has rarely been wider. On Friday, the defence group’s stock slid another 2% to €1,123.80, leaving it just a whisker above its 52-week low of around €1,118. Over the past month, the shares have haemorrhaged roughly a quarter of their value, wiping out billions in market capitalisation even as the company’s order pipeline swells to a record €73 billion.

The immediate trigger for the sell-off was a first-quarter earnings report that failed to match market hopes. Revenue climbed to €1.94 billion, but analysts had pencilled in a bigger number. Operating profit rose 17% to €224 million, a solid improvement on paper, yet still wide of consensus estimates. The real headache, however, sits on the cash flow statement. Free cash flow swung to minus €285 million, a deep hole the management attributes to deliberate inventory building to ensure it can actually deliver on its mountainous backlog.

That backlog, which includes a newly integrated naval business, is the company’s central growth narrative. Rheinmetall has completed the takeover of Lürssen’s NVL unit, turning itself into a full-spectrum shipbuilder overnight. The naval segment alone contributes €5.5 billion to the order book and has already started generating operating profit. Chief executive Armin Papperger has stuck by the full-year guidance: revenue of around €14 billion and an operating margin of 19%. He has promised a sharp acceleration in the second quarter, but investors appear to be demanding proof before giving the stock the benefit of the doubt.

Analyst opinion is divided. JPMorgan recently cut its stance to “Neutral” and lowered its price target to €1,500, citing concerns over the product portfolio. Barclays takes the opposite view, arguing the pullback is overdone given the long-term nature of the European defence cycle. Warburg Research has also issued a buy recommendation after the rout, pointing to the naval expansion as an underappreciated catalyst.

Beyond the quarterly numbers, geopolitical crosswinds are adding to the unease. Donald Trump’s brief announcement of a three-day ceasefire in Ukraine rattled defence stocks. Bernstein analysts warned that a lasting peace would hit land-systems producers such as Rheinmetall especially hard. Yet the underlying demand drivers remain in place: NATO members are still under pressure from Washington to raise defence spending, and European armies urgently need to modernise their equipment.

Rheinmetall is also widening its technology base. Earlier this month it announced a partnership with Deutsche Telekom to build a digital shield against drones, combining secure 5G networks with advanced sensors to protect critical infrastructure. The move underscores the company’s ambition to become a one-stop shop for all military domains, from munitions to naval vessels to electronic warfare.

Chart watchers now have €1,118 in their sights. A break below that level could trigger another wave of selling. The next hard test for the bull case comes on 6 August 2026, when Rheinmetall publishes its half-year results. By then the market will know whether Papperger’s pledge of a growth spurt has been met — or whether the chasm between a record order book and the share price is set to widen further.
