European Defence Spending Creates New Investment Opportunities

Investment & Market Insights | 2026

Europe’s defence industry has entered a period of structural change. Rising geopolitical risks, pressure for greater European strategic autonomy and substantially higher government defence budgets are creating a potentially significant long-term market for European aerospace and defence companies.

For investors, 2026 is therefore an important year to examine European defence stocks—not simply as a short-term geopolitical trade, but as companies positioned to benefit from potentially higher procurement, ammunition production, missile defence, military electronics, drones, cybersecurity and next-generation aerospace programmes.

The European Commission’s Readiness 2030 strategy aims to create conditions for up to €800 billion of additional defence expenditure, while EU defence expenditure reached an estimated €381 billion in 2025, almost 63% higher than in 2020.

However, investors should also recognise that defence stocks are no longer universally cheap. Several companies experienced substantial share-price gains during the European rearmament rally, and valuations can now reflect significant expectations for future growth. Recent market performance has demonstrated that even companies benefiting from strong defence budgets can experience considerable volatility.

Why European Defence Stocks Matter in 2026

Europe’s defence requirements have changed significantly since Russia’s full-scale invasion of Ukraine. Governments are seeking to rebuild ammunition inventories, strengthen air and missile defence, expand drone capabilities, modernise armoured vehicles and improve military communications and electronic warfare.

The EU’s Readiness 2030 framework includes major initiatives such as the European Drone Defence Initiative, European Air Shield, European Space Shield and Eastern Flank Watch.

The investment implications extend beyond traditional weapons manufacturers. Defence electronics, sensors, radar, cybersecurity, space technology, propulsion systems and advanced communications are becoming increasingly important components of modern military capabilities.

This creates opportunities for both traditional defence contractors and diversified aerospace companies.

European Defence Stocks to Watch in 2026

1. Rheinmetall

Germany’s Rheinmetall has become one of the most closely watched European defence companies. Its portfolio includes ammunition, military vehicles, weapons systems, air defence and defence electronics.

The company has been one of the major beneficiaries of Europe’s increased emphasis on ammunition production and military readiness. Rheinmetall is also expanding production capacity and developing international partnerships, including cooperation with Lockheed Martin on ATACMS missile production.

For investors, the attraction is the company’s direct exposure to European rearmament.

Key consideration: Expectations are already high, meaning valuation and execution risk deserve close attention.

2. Leonardo

Italy’s Leonardo provides exposure to helicopters, defence electronics, aircraft, cybersecurity and other aerospace and defence technologies.

Leonardo raised its 2026 guidance in July after strong second-quarter performance. The company increased its expected 2026 orders to approximately €28.2 billion, compared with previous guidance of €25 billion, while its defence electronics division accounted for a substantial proportion of quarterly bookings.

Leonardo therefore represents an interesting combination of European defence exposure, electronics capabilities and international programmes.

Key consideration: Investors should monitor execution, acquisitions, cash generation and the company’s ability to convert its order pipeline into profitable growth.

3. Thales

France’s Thales has a diversified technology portfolio covering defence electronics, radar, communications, cybersecurity, aerospace and digital systems.

Its positioning is particularly relevant as European governments increasingly focus on sophisticated military technology rather than simply increasing the quantity of conventional equipment.

Thales has also been investing in emerging defence technologies. In 2026, global defence companies—including Thales—have increased investment in start-ups working on autonomous systems, maritime robotics and other next-generation technologies.

Key consideration: Investors should assess the company’s valuation and the growth contribution from defence electronics, cybersecurity and advanced technologies.

4. Safran

Safran provides exposure to aerospace propulsion, aircraft equipment and defence-related technologies. Its diversified business model means it is not a pure-play defence company, which can provide investors with exposure to both commercial aerospace recovery and military-related demand.

The company is particularly relevant to the European aerospace ecosystem because advanced engines, navigation systems and aircraft components are strategically important to defence programmes.

Key consideration: Safran’s investment profile is influenced by both commercial aviation and defence cycles, so it should not be viewed as a pure defence-budget investment.

5. Airbus

Airbus is another diversified European aerospace company with significant defence and space activities alongside its large commercial-aircraft business.

Its defence exposure includes military aircraft, satellites, secure communications and other aerospace systems. This provides investors with a broader European aerospace investment rather than a concentrated pure-play defence position.

The diversification can be an advantage, but it also means that Airbus’s financial performance is affected by commercial aviation demand, aircraft production rates and supply-chain constraints.

Key consideration: Investors should analyse the commercial aerospace cycle alongside defence spending.

6. Saab and Kongsberg: European Defence Exposure Beyond the EU

Investors should distinguish between EU defence stocks and European defence stocks. Sweden and Norway are European countries but are not EU member states.

Sweden’s Saab has nevertheless become an important European defence company, particularly through fighter aircraft, surveillance systems, missile systems and defence electronics. Norway’s Kongsberg also has significant exposure to missile systems, air defence, command-and-control and maritime technologies.

Both illustrate the broader European defence investment theme beyond EU-listed companies.

Features and Highlights

The table is intended as an educational comparison, not a ranking or investment recommendation.

The Defence Technology Opportunity

One of the most important developments for investors is the transformation of modern warfare.

Defence spending is increasingly moving toward:

• Drones and counter-drone systems
• Artificial intelligence
• Cybersecurity
• Electronic warfare
• Missile and air defence
• Satellites and space systems
• Autonomous maritime systems
• Precision-guided weapons
• Military communications
• Advanced sensors and radar

This means investors should look beyond traditional manufacturers of tanks, aircraft and ammunition.

European defence companies are increasingly investing in start-ups and emerging technologies. Global defence giants invested approximately $4.1 billion in defence-related venture capital rounds during 2026, reflecting the industry’s growing focus on autonomous and disruptive technologies.

Europe’s €800 Billion Defence Ambition

The scale of Europe’s defence plans is central to the 2026 investment thesis.

The European Commission says the Readiness 2030/ReArm Europe framework aims to mobilise €800 billion to strengthen European defence capabilities. The plan is designed to give member states greater financial flexibility while encouraging increased defence investment.

For defence manufacturers, this could translate into a multi-year pipeline of government procurement.

But there is an important distinction between announced spending and actual company revenue. Government budgets must ultimately be converted into procurement contracts, production capacity and deliveries. Investors should therefore monitor order intake, backlog, margins and free cash flow rather than relying solely on headline government spending figures.

Are European Defence Stocks Still Attractive?

This is perhaps the most important question for investors in 2026.

The long-term industry outlook remains supported by higher defence budgets and changing European security priorities. However, several major defence stocks have already experienced extraordinary share-price appreciation.

Recent analysis has noted that European defence stocks lost some of their earlier momentum during 2026 despite large spending commitments, illustrating the importance of valuation and expectations.

Consequently, investors should avoid assuming that higher defence spending automatically means every defence stock will rise.

A company can have excellent long-term fundamentals but still be an unattractive investment if its share price already reflects excessive future growth.

What Investors Should Watch

Before investing in European defence stocks, investors should examine five key indicators:

1. Order backlog: A large backlog can provide visibility into future revenue.

2. Production capacity: Companies need factories, skilled workers and supply chains capable of meeting increased orders.

3. Cash flow: Revenue growth does not necessarily translate into free cash flow.

4. Valuation: Price-to-earnings, price-to-sales and enterprise-value measures should be considered alongside growth expectations.

5. Government procurement: Investors should distinguish between political announcements and signed contracts.

Conclusion

EU and European defence stocks have become one of the most important investment themes of 2026. The European Commission’s Readiness 2030 strategy, rising national defence budgets and growing demand for advanced military technology could support a multi-year expansion of the European defence industry.

Rheinmetall, Leonardo, Thales, Safran and Airbus provide different forms of exposure, while Saab and Kongsberg offer additional opportunities within the wider European defence ecosystem.

Nevertheless, defence investing requires selectivity. Strong government spending does not guarantee strong shareholder returns, particularly when valuations already incorporate substantial future growth.

For investors considering this sector, the most attractive opportunities may ultimately be companies combining strong order books, technological leadership, production capacity, disciplined capital allocation and reasonable valuations.

Savings UK Ltd (StockExchange.EU) recommends that investors treat defence stocks as part of a diversified portfolio rather than as a standalone investment strategy. Investors should conduct independent research and consider their objectives, risk tolerance and investment horizon before making investment decisions.
