BAE Systems PLC shares rose sharply on Monday, gaining 5.5% as markets reacted to heightened tensions in the Middle East and fresh commentary from JPMorgan on the defence sector's prospects.
In a research note, JPMorgan analysts said the European defence sector looks poised to rally amid ongoing conflicts and the prospect of increased US military expenditure. The bank cited comments from President Trump in January 2026 indicating an intention to raise the US defence budget by 50% in fiscal 2027. JPMorgan qualified that view, saying a 20-30% increase may be a more realistic expectation.
The analysts also pointed to a higher tempo of US military operations through 2026 as a driver of pressure to lift defence spending. Against that backdrop, JPMorgan highlighted BAE Systems as one of the European contractors most likely to benefit, noting that roughly 44% of the company's sales come from the US defence market - the largest share among the European defence companies the bank covers.
JPMorgan further stressed the near-term requirement for the US to replenish missile inventories following recent operational use. The bank referred to media reporting from June 2025 that suggested the US expended 15-25% of its total THAAD interceptor stock during a 12-day engagement, equal to about 100 to 150 interceptors from an inventory estimated at approximately 650 units.
BAE supplies the infrared seeker element used in the THAAD guidance system. JPMorgan estimated that BAE earns about $1 million per THAAD unit for this component, underscoring a tangible revenue linkage to missile restocking if demand rises.
Other UK-listed defence names moved higher on Monday as well. Babcock International Group PLC rose 0.9%, and Qinetiq Group PLC was up about 3% as of 11:00 AM GMT. JPMorgan also identified several continental European firms with notable US defence exposure: RENK Group AG at around 25%, Leonardo SpA at roughly 23%, and Qinetiq at about 18%.

Market context
The share moves reflect immediate investor attention on defence contractors with high US exposure amid reports of intensified military activity and the potential for a material uplift in US defence budgets. The specifics cited by JPMorgan - President Trump’s January 2026 statement of intent and the bank’s more conservative 20-30% budget increase scenario - frame investor expectations without asserting a definitive outcome.
BAE’s substantial US revenue share and its role in supplying components for missile systems create a direct link between operational demand and potential revenue upside should restocking occur.
