UK Defence Stocks: Value or Value Trap in 2026?
Increased NATO spending has fuelled UK defence stock prices. We analyse whether the fundamentals support current valuations.
UK defence stocks have been one of the strongest-performing sectors in the FTSE since Russia's Ukraine invasion in 2022. BAE Systems is up over 160% from its 2022 low. Rolls-Royce has retraced from £0.75 to over £6. The question for a value investor: at these prices, is there still value — or has the re-rating already happened?
The Macro Backdrop
NATO's 2% GDP defence spending target is now a hard commitment rather than an aspiration. The UK government has pledged to reach 2.5% by 2027, with cross-party support for further increases. European NATO members collectively are adding approximately £150bn of annual procurement. This is structural, multi-year demand growth that justifies a re-rating of earnings multiples.
| Company | Where it sits |
|---|---|
| BAE Systems | Large prime contractor; strong order book, but the multiple has already re-rated with the sector. |
| Rolls-Royce | Sharp recovery from the 2022 low; growth is now largely priced in on a forward-earnings basis. |
| QinetiQ | Test-and-evaluation niche with switching costs; historically trades cheaper than the primes. |
Value vs Value Trap: The Distinction
The value investor's concern with defence stocks at current levels: the re-rating has largely already happened. The large primes now trade well above their historical earnings multiples — the order-book growth is real, but much of it is already priced in. Names with a more defensible niche and high switching costs, such as test-and-evaluation specialists, are more consistent with a genuine value opportunity. Check current multiples against each company's latest results before drawing conclusions.
AIM Defence Names
Some of the more interesting value opportunities in UK defence sit on AIM, where smaller suppliers of components, cyber security and specialist electronics can trade at discounts to the large primes. These require deeper due diligence given liquidity constraints and higher single-stock risk. Use the screener and the insider feed to find current candidates rather than relying on any fixed list.
