Rheinmetall earnings: a miss, a margin win, and a much bigger defence story

The quarter was not bad. It was awkward.

The first-quarter miss had several moving parts. Vehicle Systems sales were held back by military trucks already produced but not yet called off by the German armed forces. Weapon and Ammunition sales were slower than expected, partly due to the ramp-up of the Murcia ammunition plant in Spain after a fire in 2025. Naval Systems added only one month of contribution after the acquisition closed.

That matters because Rheinmetall’s 2026 guidance is ambitious. Management still expects sales of 14 billion EUR to 14.5 billion EUR this year and an operating margin of around 19%. To get there, the year needs a much stronger second half. This is not unusual in defence, where large deliveries can land unevenly. But it does raise the bar for execution.

The positive side is the order book. Rheinmetall’s backlog reached 73 billion EUR at the end of March, up strongly from a year earlier and helped by 5.5 billion EUR from Naval Systems. Backlog is not the same as cash, but it is visibility. For a business that builds complex equipment over long periods, visibility is valuable. A full restaurant is good. A full kitchen still needs chefs.

Europe is moving from speeches to spending

Rheinmetall’s quarter sits inside a much larger European shift. The European Union (EU) is trying to mobilise up to 800 billion EUR for defence under its Readiness 2030 plan. The North Atlantic Treaty Organization (NATO) has also moved the spending debate higher, with allies committing to spend 5% of gross domestic product (GDP) on core defence and broader security-related areas by 2035.

For investors, the important point is not the exact political slogan. It is the direction. European countries are trying to rebuild ammunition stocks, strengthen air and missile defence, modernise vehicles, add drones, improve cyber defence and secure supply chains. The shopping list is long. Sadly, there is no “add all to basket” button.

Rheinmetall is trying to position itself across that list. It has moved into naval systems through Naval Vessels Lürssen and has submitted a non-binding offer for German Naval Yards Kiel. It is also in talks with Middle East customers for up to 10 air-defence systems for delivery in 2026. The company is no longer just a land-vehicles and ammunition story. It wants to be a broader European defence platform.

That broader scope is useful, but it adds complexity. Shipyards, ammunition plants, electronics, skilled labour, explosives, regulation and export approvals all have their own bottlenecks. More demand helps, but production still needs permits, people and parts.

Orders are not earnings

The key investor lesson is simple: defence is becoming more attractive strategically, but the business model is not magic. Governments place orders. Companies invest in capacity. Suppliers scale up. Products get delivered. Cash arrives later. Sometimes much later.

That makes Rheinmetall a useful case study for the whole sector. A large backlog supports future sales, but margins decide how much profit comes through. Working capital, meaning cash tied up in inventory and receivables, can rise when companies build ahead of delivery. Rheinmetall’s operating free cash flow was negative in the quarter, partly because inventory rose to support future growth.

This is why investors should look beyond order headlines. The useful questions are practical. Can the company deliver on time? Are margins improving or being squeezed by labour and material costs? Is cash flow following profit? Are budgets turning into signed contracts? In defence, the battle for returns is often fought in procurement offices and production halls, not only on the front page.

Risks: the boom still has brakes

The first risk is execution. Rheinmetall’s guidance depends on a strong catch-up in the coming quarters. Early warning signs would include further delivery delays, slower call-offs from governments, weaker margins or another rise in cash tied up in inventories.

The second risk is politics. Defence spending is rising, but governments still face budget pressures. If growth slows, debt concerns rise or elections change priorities, some programmes could be delayed. Defence is strategic, but it still needs parliamentary approval. Democracy has many strengths. Speed is not always one of them.

The third risk is technology. Recent conflicts have increased demand for drones, air defence, missiles, electronic warfare and ammunition. Traditional platforms like tanks and armoured vehicles still matter, but investors should watch whether future budgets keep shifting toward faster, cheaper and more digital systems.

Investor playbook

• Separate defence-policy momentum from company execution. Bigger budgets only matter when they become deliveries.

• Compare backlog growth with margins and cash flow. Orders are useful, but cash pays the bills.

• Think across the supply chain: ammunition, sensors, cyber, shipyards, vehicles, logistics and power infrastructure.

• Keep valuation discipline. A good theme can still become expensive when everyone sees it.

The factory floor has the final word

Rheinmetall’s quarter is a useful reminder that Europe’s defence story has entered a new phase. The easy part was recognising that Europe needs to spend more. The harder part is building the factories, ships, shells, systems and supply chains that turn policy into readiness.

Rheinmetall has the backlog, market position and strategic relevance to remain central to that story. It also has the execution burden that comes with being central. For long-term investors, the lesson is balanced: Europe’s defence cycle looks structural, but returns will depend on delivery. In this market, the order book opens the door. The factory floor decides who walks through it.
