3 Defense Stocks Worth Watching As Europe Security Spending Rises

Geopolitics in Eastern Europe has moved from background noise to front page risk, and markets are already recalibrating security premiums and defense spending expectations. That shift can create pockets of opportunity and pockets of trouble for listed companies exposed to this news. This article walks through 3 stocks from our Defense and Aerospace Stocks screener that appear positioned as potential beneficiaries and explains what this might mean for your portfolio decisions.

The three defense and aerospace stocks highlighted below are only a sample, and the full screen surfaced 32 more well-capitalized contractors and manufacturers with equally compelling narratives that are not covered here. To go straight to the broader opportunity set, use the Defense and Aerospace Stocks screener to identify, filter, and analyze the highest conviction ideas for your own watchlist.

Enpro (NPO)

Overview: Enpro is an industrial technology company that protects critical environments through sealing and advanced surface technologies for semiconductor, aerospace and defense linked infrastructure.

Operations: Enpro generates about US$780 million from Sealing Technologies and US$444 million from Advanced Surface Technologies across the United States, Europe and Asia Pacific.

Market Cap: US$7.0b

Enpro matters in this defense and aerospace screen because its sealing and surface solutions sit inside the secure facilities and components that rising security budgets tend to rely on, which is exactly where the latest geopolitical headlines are pushing more attention and capital.

"Capacity expansions in Enpro’s Advanced Surface Technologies business, including higher 2026 capital expenditure directed toward facilities in Arizona, Milpitas and Taiwan, are aligned with customer build plans that currently provide visibility through 2027 and are expected to influence future revenue and segment margins as this semiconductor and AI investment cycle plays out."

The real swing factor for Enpro is what happens if a single key assumption about future demand strength quietly starts to shift.

That swing factor is exactly what the full narrative for Enpro unpacks, showing how demand visibility, capex timing and contract risk could be quietly accelerating or masking Enpro’s real potential.

Lisi (ENXTPA:FII)

Overview: Lisi S.A. supplies fasteners and structural components for aircraft, plus assembly parts for automotive and medical clients worldwide.

Operations: Lisi generates about €1.25b from LISI Aerospace and €546 million from LISI Automotive, with minor other items.

Market Cap: €2.80b

Lisi plugs directly into the Defense and Aerospace Stocks screener because its aerospace fasteners and structural assemblies feed into aircraft hardware used across civilian and defense programs. Investors gain exposure to European defense spending through a parts supplier with a focus on profitability, while a key consideration is how long aircraft customers continue to support that margin profile before any additional pressure emerges.

That margin pressure question makes the 4 key rewards and 1 important warning sign for Lisi a useful shortcut to see where profitability might be quietly accelerating or at risk of stalling.

Vicor (VICR)

Overview: Vicor designs and sells modular power components that convert and manage electricity inside high performance electronics, including defense and aerospace systems.

Operations: Vicor generates about US$474 million from advanced brick power products, primarily across the United States, Asia Pacific and Europe.

Market Cap: US$14.1b

Vicor matters for this defense and aerospace screen because its power modules and licensing model sit inside the high density electronics that rising security budgets increasingly rely on.

"Vicor is positioning its fifth generation current multiplier and second generation vertical power delivery as the only way many hyperscalers and OEMs can meet upcoming current density targets above 3 amperes per square millimeter."

The key question for Vicor is how outcomes might change if a single assumption about the pace at which that power architecture is adopted across defense electronics were to shift.

If that adoption curve matters to you, read the full narrative for Vicor to see what might be accelerating, stalling or quietly masking Vicor’s real defense exposure.
