3 Airport Infrastructure Stocks That Could Benefit From Nats Outages

Simply Wall St·09/21/2026 21:28:00
Listen to the news

Repeated outages at UK air traffic control agency Nats have turned routine travel into a live stress test for airports and ground services, and that disruption is now rippling through listed stocks. When reliability is in question, companies tied to airport infrastructure, IT resilience and on-the-ground operations can suddenly look very interesting. This article unpacks three such stocks exposed to this news, and why their role in keeping planes moving might matter for your portfolio.

The stocks covered below are only a sample of the idea, and the full screen surfaced 7 more UK and European airport and ground-handling companies with equally compelling narratives that are not discussed in this article. To go deeper into this theme, head straight to the UK & European Airports and Ground Services Resilience Beneficiaries screener to identify, filter and analyze the resilience plays that best fit your own criteria.

Serco Group (LSE:SRP)

Serco Group taps into the screener theme from the public services angle, running complex government outsourcing contracts that can include transport, terminal operations and facilities management linked to airports, where resilience and contingency planning are becoming a bigger focus.

Serco Group runs outsourced public services across transport, defense, health, justice and facilities management, including aviation related operations. Most revenue comes from the United Kingdom & Europe segment at about £2.7b, with £1.5b from North Americas and £0.6b from Asia Pacific. The stock’s market cap is about £2.5b.

The convergence of rising global tensions around border control, migration, and national security is structurally expanding government outsourcing in Serco's core markets, placing the company at the center of multi-decade secular trends that can expand revenue and margin as demand for outsourced justice, immigration, and border management increases.

For airport resilience investors, a single unseen pressure on how governments fund and structure these contracts could be the real swing factor.

That contract risk is only half the story, and the full narrative for Serco Group shows how Serco Group’s outsourcing model could accelerate or stall as resilience spending evolves.

Mitie Group (LSE:MTO)

Mitie Group plugs into the airport resilience theme as a facilities and technical services provider that keeps large sites functioning, from terminals and data centers to critical infrastructure, giving you exposure to the behind the scenes work that supports smoother aviation operations.

Mitie Group runs facilities management and technical services across sectors including transport and aviation, drawing about £3.0b from Business Services and £2.6b from Technical Services, and carries a market value of roughly £2.7b.

Expansion of project work linked to data centers, power and grid connections, battery storage and retrofitting of the built environment is increasing the mix of higher value work, which can support project revenue and potentially lift group earnings quality.

The key factor for Mitie Group is how one evolving stream of higher value work ultimately flows through to margins and cash generation.

That margin question is only the start, and the full narrative for Mitie Group lays out how Mitie Group’s shifting work mix could accelerate earnings quality or leave value still masked.

Aena S.M.E (BME:AENA)

Aena S.M.E gives you direct exposure to airport resilience because it owns and runs a large network of airports, where any push for more reliable systems directly affects passenger flows and commercial activity across its terminals.

Aena S.M.E manages airports and terminal services across Spain, Brazil, the UK, Mexico and Colombia, with most revenue tied to aeronautical fees of about €3.4b and commercial activities of roughly €2.0b, alongside international airports and real estate services, and carries a market value near €38.1b.

Ongoing expansion and modernization initiatives, including large-scale CapEx for airport terminals, commercial space build-out, and logistics, are intended to help Aena address both passenger traffic trends and retail/real estate income in future years, with a focus on long-term revenue and operational efficiency.

What ultimately happens to returns will depend on how one unresolved regulatory decision shapes the balance between future pricing power and required investment.

That pricing hinge is where things get interesting, and the full narrative for Aena S.M.E shows how Aena S.M.E’s capital cycle, regulation and returns could be decoupling.
