Geopolitical Risk and European Infrastructure Stocks: Navigating Hybrid Threats and Defense Demand

The European infrastructure landscape in 2025 is defined by a dual-edged sword: escalating geopolitical risks that threaten critical systems and a surge in defense spending that is reshaping corporate performance. As hybrid and cyber threats intensify, investors must weigh the vulnerabilities of airport operators against the robust growth of defense contractors. This analysis examines the interplay between these sectors, drawing on recent disruptions and strategic responses.

Hybrid Threats and Airport Vulnerabilities

European airports have emerged as prime targets for hybrid attacks, which combine physical and digital disruptions. In September 2025, a ransomware attack on Collins Aerospace's MUSE software crippled check-in and baggage systems at Brussels, Heathrow, and Berlin Brandenburg airports, forcing manual operations and causing widespread cancellationsEuropean airports cyberattack - CNBC^[1]. Simultaneously, drone incursions at Copenhagen and Oslo airports—attributed to a “capable operator”—exposed gaps in physical security, with Danish authorities describing the incident as the “most serious attack on Danish critical infrastructure to date”Drones And Cyberattacks Plague European Airports^[2]. These events underscore the fragility of interconnected systems and the growing sophistication of adversaries.

The financial toll is evident. Brussels Airport canceled half its flights in one day due to unresolved software issuesEuropean airports cyberattack - CNBC^[1], while Copenhagen Airport faced operational halts and reputational damage from drone disruptionsKøbenhavns Lufthavne A/S (KBHL.CO) Stock Price^[3]. Despite these challenges, some operators have shown resilience. Avinor, Norway's airport operator, reported a 15.8% year-on-year increase in operating revenues in H1 2025, driven by traffic growth and tax revenuesAvinor’s H1 2025 Performance^[4]. However, the broader sector faces headwinds: European air connectivity remains 9% below pre-pandemic levels, with non-EU+ markets hit hardest by geopolitical tensionsEurope’s Air Connectivity and Geopolitical Shifts^[5].

Defense Contractors: Beneficiaries of the Security Boom

While airports grapple with threats, defense contractors are capitalizing on a €800 billion EU ReArm Europe Plan. Companies like Airbus, BAE Systems, and Leonardo have seen record order books, with Airbus reporting €16.7 billion in defense and space division intake in 2025The Top European Defense Stocks for 2025^[6]. The demand for air defense, cyber warfare, and next-generation combat systems has fueled a 15% rise in European defense sector order books and a 35% surge in M&A activityRising Geopolitical Tensions Ignite European Defense M&A^[7].

Stock performance reflects this momentum. BAE Systems, with a £77.8 billion backlog, has benefited from programs like the Global Combat Air Programme and AUKUS submarine dealsThe Top European Defense Stocks for 2025^[6]. Similarly, Leonardo's partnerships in armored vehicles and cyber defense have driven growthThe Top European Defense Stocks for 2025^[6]. The sector's resilience is further bolstered by geopolitical uncertainty: the 2025 NATO Summit in The Hague is expected to trigger intensified Russian hybrid operations, including AI-driven disinformation and cyber espionageThreats to the 2025 NATO Summit^[8].

Investment Implications: Contrasting Trajectories

The contrasting trajectories of airport operators and defense contractors highlight divergent risk-return profiles. While airports face short-term operational and reputational risks, their long-term outlook depends on cybersecurity investments. For instance, the airport security market is projected to grow at 11.5% CAGR, reaching $45.5 billion by 2034, driven by AI-powered threat detection and biometric systemsAirport Security Market Outlook Report 2025-2034^[9]. However, stock performance remains mixed: Copenhagen Airport's shares rose 0.30% post-incidentKøbenhavns Lufthavne A/S (KBHL.CO) Stock Price^[3], but broader sector indices lag behind the robust gains of defense stocks.

Defense contractors, meanwhile, are insulated by structural tailwinds.

Conclusion

The 2025 geopolitical landscape presents a paradox for European infrastructure stocks. Airport operators face acute risks from hybrid threats, yet their long-term value hinges on successful modernization. Defense contractors, meanwhile, are poised to benefit from a security-driven renaissance, albeit with regulatory and strategic challenges. For investors, the key lies in balancing exposure to resilient defense plays with cautious optimism toward airports that prioritize cybersecurity and operational agility.
