Since September 2020, there are 9 firms on the FTSE 100 which have seen their share costs rise by greater than 300%. Of those, three have publicity to the army sector.
And it’s not simply within the UK the place elevated defence spending helps increase share costs of the business’s contractors. The STOXX Europe Whole Market Aerospace & Protection index has returned 318% over the identical interval. For comparability, European shares as an entire have delivered a 50% enhance.
Though I acknowledge that investing within the sector isn’t to everybody’s liking, I imagine it’s the first responsibility of a authorities to guard its individuals. And given the share worth actions of the UK’s three greatest listed suppliers within the sector, others seem to agree with me.
Let’s take a more in-depth look.
A finger in lots of pies
In 2024, Rolls-Royce Holdings generated 25% of its income and 26% of its underlying working revenue from its defence division.
And though this a part of the enterprise is performing effectively, I feel it’s the post-pandemic restoration in air journey that has been the first purpose for the group’s share worth growing by greater than 2,000% over the previous 5 years.

However there are two different FTSE 100 members which are pure defence shares.
Controversially, the BAE Methods (LSE:BA.) share worth has benefitted most from the tragic conflict in Ukraine. Like others within the business, nearly all of its income is earned from multi-year contracts. At 30 June, the group reported an order backlog of £75.4bn – roughly thrice its annual gross sales.
It’s the most important provider to the Ministry of Defence so it ought to profit from the federal government’s dedication to spend 2.5% of GDP on the UK’s military, navy and air drive from April 2027.
Nevertheless, the group’s inventory isn’t low-cost. Analysts expect earnings per share (EPS) in 2025 of 75p. If appropriate, this suggests a ahead price-to-earnings (P/E) ratio of 26.9. That is effectively above the Footsie common. And with a yield of 1.7%, there are higher earnings alternatives elsewhere.
However I feel it’s working in the proper sector on the proper time so I imagine it’s a inventory worthy of additional consideration.
One other different
The opposite FTSE 100 defence firm is Babcock Worldwide Group (LSE:BAB), having joined the index in March.
Final week (25 September), it gave a buying and selling replace forward of its annual common assembly. Not surprisingly, it described the present macro atmosphere as “supportive”.
Once more, its shares are costly. The inventory has a ahead (2025) P/E ratio of 24.9. However Europe-wide, the business is buying and selling at 31.6 occasions future earnings. So maybe it’s not as unreasonable because it initially seems.
Nevertheless, at 0.5%, its yield is even decrease than that of BAE Methods.
One other concern I’ve is that the group has incurred vital losses on one in every of its contracts with the Royal Navy. Hopefully, classes have been realized.
However it has a big (and rising) order e-book. And it says it’s on monitor (over the medium time period) to lift its underlying working revenue margin from the 5.4% it achieved in its 2025 monetary 12 months to “a minimum of 9%”. Analysts expect EPS to extend by 33% over the following three years.
For these causes, I feel it’s a inventory that long-term traders might think about.
