3 European Defence Stocks Worth Watching For Long Term Military Spending

A surge in support for Germany’s AfD is shaking assumptions about EU cohesion, euro stability and the future of European security policy. That kind of political friction can quickly reshape where risk and potential reward sit in European markets, especially for defence and security related stocks. This article walks through three stocks exposed to these headlines and explains how the changing backdrop could matter for your portfolio decisions.

The stocks covered below are only a sample of what this theme flags, with the full screen surfacing 25 more European defence and security companies that carry equally compelling narratives but do not fit into a single article. If you want to identify, compare and analyze the highest conviction ideas in this space, go straight to the European Defence & Security Stocks screener.

Invisio (OM:IVSO)

Overview: Invisio is a Malmö based defence company that supplies communication and hearing protection systems for military, law enforcement and security professionals, including headsets, intercoms and tactical hubs sold under the INVISIO and Racal Acoustics brands. For investors focused on European defence and security, it offers direct exposure to equipment that supports frontline readiness as budgets and operational demands shift.

Operations: Invisio generates essentially all of its SEK 1,918.7 million revenue from aerospace and defence, with reported geographic sales of SEK 151.7 million in Sweden and SEK 157.2 million in the rest of the world plus a SEK 1,609.7 million segment adjustment.

Market Cap: SEK10.9 billion

Invisio provides targeted exposure to defence and security spending through specialist equipment that soldiers and first responders use, now including drone detection capability integrated into its T30 headset. The company operates in a niche where hearing protection, clear communication and situational awareness are becoming higher priorities as drone threats and regulatory pressure on safety rise. Recent Q2 and H1 2026 numbers show higher sales and earnings. Its results depend heavily on large government contracts and external funding, so execution and procurement timing remain important. For investors, the combination of growth indicators, quality metrics and core defence exposure may be worth closer consideration.

Invisio’s growing role in frontline communications is attracting attention, yet many investors may not be joining the dots between contracts, margins and resilience. Get the full picture in the analysis report for Invisio

Exosens (ENXTPA:EXENS)

Overview: Exosens is a Mérignac based electro optical specialist that builds the tube, sensor and camera technology behind night vision, surveillance and targeting systems used in defence and security, alongside dual use products for life sciences, industrial and nuclear applications. Its portfolio, including brands such as Photonis and Xenics, gives investors exposure to critical sensing hardware that is difficult to replicate and relevant across multiple high stakes end markets.

Operations: Exosens generates about €337.6 million of revenue from its Amplification segment and €165.6 million from Detection and Imaging, with only a small negative contribution from other and unallocated items.

Market Cap: €2.8b

Exosens is worth a closer look for investors interested in how rising defence and security priorities translate into specific business activity. Its electro optical technology is used in night vision goggles, thermal cameras and missile warning systems that are seeing fresh demand as drone use, surveillance needs and NATO equipment upgrades increase, supported by contracts such as the long term Czech Armed Forces agreement for image intensifier tubes and a U.S. Army BiNOD order. At the same time, high growth expectations, a premium P/E and a debt heavy balance sheet highlight that the investment case carries risks. The mix of EU backed financing, capacity expansion and dual use markets presents potential opportunities, dependent on execution and the evolution of defence budgets.

Exosens sits at the crossroads of defence demand and dual use optics, yet the real story may be how its premium P/E and debt profile interact with growth expectations in the analysis report for Exosens

RENK Group (XTRA:R3NK)

Overview: RENK Group is a German engineering company that builds customized drive and propulsion systems for military tracked vehicles and naval ships, giving investors direct exposure to European rearmament and land and sea platform upgrades, while also serving industrial and energy customers. Its gearboxes, transmissions and slide bearings sit deep inside key defence hardware, which ties RENK closely to long term procurement programs and aftermarket support.

Operations: RENK Group generates most of its revenue from Vehicle Mobility Solutions at €901.9 million, followed by Marine & Industry at €369.8 million and Slide Bearings at €125.1 million, with a €13.6 million consolidation adjustment across segments.

Market Cap: €4.3 billion

RENK Group is drawing attention from defence focused investors because its drive systems are built into main battle tanks, infantry fighting vehicles and naval platforms that sit at the center of European rearmament and modernization plans, even as political debate in Germany introduces fresh questions about how defence budgets evolve. A strong order book linked to long duration contracts, growing aftermarket exposure and a recent €1,050 million unsecured refinancing provide the company with clearer revenue visibility and more flexibility to support future programs. At the same time, high leverage, reliance on government procurement and a premium valuation mean expectations are already demanding. For anyone tracking European defence stocks, the mix of opportunity and execution risk at RENK merits closer examination.

RENK’s long duration defence programs and €1,050 million refinancing suggest a story that could be more than just headline risk. See how the order book, leverage and expectations really line up in the analysis report for RENK Group
