Rheinmetall Stock: Is It Worth Buying After the 2026 Slump?

Rheinmetall stock was the star of the European defence boom. Then 2026 happened. The shares have fallen by roughly a third this year, even though sales are growing at close to 40%. So is this a buying opportunity, or a sign the easy money has gone? Here is how I see it.

What Rheinmetall Actually Does

Rheinmetall is a German company founded in 1889. It makes armoured vehicles, ammunition, military trucks and air defence systems. For decades it was a fairly quiet industrial business.

Everything changed when Russia invaded Ukraine in February 2022. European governments suddenly needed tanks, shells and air defence at scale. Rheinmetall was one of the few firms able to deliver, so orders and the share price both took off.

Why Rheinmetall Stock Has Fallen in 2026

Rheinmetall stock closed around €1,020 on 21 October 2026. That compares with a 52 week high of €1,966, so the shares have almost halved from their peak. Several blows landed in quick succession.

A Weak Start to the Year

In early February, the company pointed to 2026 sales of around €13.6 billion. That was below what the market hoped for, and the shares fell more than 9% in a day.

The F126 Frigate Cancellation

Then, on 24 June, Germany scrapped its F126 frigate programme because of delays and rising costs. Rheinmetall had a big stake in that project through its naval business. The shares dropped 19% that day, their worst fall in decades.

A Trimmed Forecast

In August, Rheinmetall cut its 2026 sales guidance to between €13.7 billion and €14.2 billion. It also lowered its year end order book target. More recently, some brokers have cut their price targets, arguing that the company needs even more orders to keep growing beyond 2030.

The Numbers Behind the Business

Despite the falling share price, the business itself is still growing quickly. According to its half year report, the first six months of 2026 showed:

• Sales of €5.2 billion, up 39%.
• An operating result of €786 million, up 74%.
• An operating margin of 15%, up from 12.1%.
• A record order backlog of €80.5 billion.

In other words, the gap between the business and the share price has widened. That is exactly the kind of situation that can create value, but it can also be a warning that expectations were simply too high.

The US Army Opportunity

Meanwhile, Rheinmetall’s American arm is one of two finalists to replace the US Army’s Bradley fighting vehicle, a programme known as XM30. Its Lynx prototype has already been delivered to the Army. The winner is expected to be chosen by the end of 2027.

Winning would give Rheinmetall a huge foothold in the world’s biggest defence market. Losing would remove one of the main pillars of the long term growth story. Either way, it is a binary event worth watching.

The Risks Before You Buy Rheinmetall Stock

First, peace talks matter. Any genuine move towards a settlement in Ukraine tends to knock defence shares, even though European rearmament plans run for years regardless.

Second, cash flow has been weak. Rheinmetall burned cash in the first half because of stock building and slow customer payments. That needs to improve as big orders turn into deliveries.

Third, single stock risk is real. This share has already fallen almost 50% from its high in less than a year. If that would keep you up at night, my post on the psychology of investing is worth a read first.

How UK Investors Can Buy Rheinmetall Shares

Rheinmetall trades in Frankfurt under the ticker RHM. Platforms such as Interactive Brokers, IG and Trading 212 offer access to German shares. Because it is priced in euros, your returns also move with the pound to euro exchange rate.

It is worth checking whether your platform lets you hold European shares in a stocks and shares ISA. My guide to the types of ISA explains how the tax wrapper works. Outside an ISA, gains above your annual allowance may be subject to capital gains tax.

Alternatively, European defence ETFs hold Rheinmetall alongside other names, which spreads the risk. My guide to ETFs covers how these funds work.

Rheinmetall Stock FAQs

Why did Rheinmetall stock drop so much in 2026?

Mainly a cautious sales outlook in February, the F126 frigate cancellation in June and a guidance cut in August. Peace talk headlines have added pressure too.

Is Rheinmetall still growing?

Yes. First half sales rose 39% and the order backlog reached a record €80.5 billion. The question is whether growth can live up to the very high expectations that were built into the share price.

Can I hold Rheinmetall in an ISA?

Often, yes, as long as your platform offers German shares inside its ISA. Check with your provider before buying.

My Take on Rheinmetall Stock

Rheinmetall stock is far cheaper than it was a year ago, while the business keeps growing. That makes it more interesting than it was at the peak. Even so, the next leg depends on turning a huge backlog into cash and winning big contracts such as XM30.

If I bought, I would keep it to a small slice of a diversified portfolio and be ready to hold through more big swings.
