UK small and mid-cap defence stocks have risen 37% over the past 12 months, significantly outpacing their large-cap peers, as higher defence budgets and a shift towards technology-led procurement create opportunities for specialist suppliers, according to broker Cavendish.
The catalyst for UK defence stocks has moved beyond a near-term budget surge towards funded programmes, formal approvals and contract timing, with the Defence Investment Plan (DIP) setting the direction for spending priorities.
The DIP is the government's £298 billion four-year strategic framework.
And the investment bank remains positive on eight companies it covers, including Solid State PLC (AIM:SOLI), Concurrent Technologies (AIM:CNC), Filtronic PLC (LSE:FTC), Pennant International Group PLC (AIM:PEN), SRT Marine Systems PLC (LSE:SRT), RC Fornax PLC (AIM:RCFX), Avingtrans PLC (AIM:AVG, FRA:DZR) and Calnex Solutions PLC (AIM:CLX, FRA:CSO).
For that, it cited capabilities in areas aligned with the fastest-growing elements of defence modernisation.
The DIP, published on 30 June following a 10-month delay, sets a path towards defence spending of 2.7% of gross domestic product by 2027, with the 3.5% target by 2035 unchanged.
The timing of a 3% commitment is deferred to the spring spending review.
Priority allocations include the nuclear deterrent, combat air, munitions, autonomous maritime systems, artificial intelligence, cyber, space and electronic warfare.
UK large-cap defence companies are down a marginal 0.7% over three months on a forward price-to-earnings ratio of 17.2 times.
Smaller peers are down 3.0% on 22.9 times, a premium Cavendish considers justified given superior structural growth and scalable specialist capabilities.
Further sector upside requires sustained order intake, conversion of backlogs into revenue, margin progression and cash generation, with stock performance expected to depend increasingly on formal programme approvals and contract award timing.
