European defence and security stocks are suddenly back in the spotlight as EU leaders weigh using €210b of frozen Russian assets and confront a potential €70b funding gap for Ukraine. That mix of fresh money, political risk and talk of Eurozone cohesion puts a price tag on Europe’s security choices. This article walks through three stocks exposed to this story and how the shifting backdrop could affect their investment case.
The three stocks covered next are only a sample of what rises to the surface, and the full screen identified 25 more listed European defence and security contractors with equally compelling stories that are not discussed here. To size up that broader universe, head straight into the European Defence and Security Contractors screener to filter, analyze, and identify the highest conviction ideas for your own watchlist.
Invisio (OM:IVSO)
Overview: Invisio develops communication and hearing protection systems for defence, law enforcement, and security professionals, giving it direct exposure to European security spending.
Operations: Invisio generates SEK 2.0b in revenue from Aerospace & Defense products, with reported sales mainly split between Sweden and the Rest of the World.
Market Cap: SEK 10.1b
Invisio sits directly within this defence-focused screen, supplying the communication gear that turns higher budgets into field-ready capability. The bullish analyst narrative on Simply Wall St highlights that the key development now is how Invisio’s role is evolving inside larger equipment programs.
"Growing interest in complete soldier and vehicle communication setups that include headsets, control units, intercoms and hubs is pushing Invisio further into system integrator roles. This can shift revenue mix toward larger multi component deals and support EBIT margin against the 20% target."
The central question for Invisio is how emerging pressure on its mix between own equipment and bundled systems will shape future profitability.
That profitability mix is the real swing factor here, and the full narrative for Invisio tracks how Invisio’s system role, contract structure and risks could be evolving next.

Theon International gives investors exposure to European defence and intelligence spending, with night vision and ISR hardware already winning fresh NATO related contracts and backed by upgraded 2026 guidance.

That unseen pressure is exactly what the full narrative for Dassault Aviation société anonyme unpacks, distinguishing routine backlog delivery from scenarios in which earnings visibility accelerates or quietly stalls.
