Babcock FY26 trading update: strong core growth, but the Type 31 frigate hit is hard to ignore
Babcock has delivered a better underlying year than the headline profit number first suggests. Revenue rose to £5,273 million, free cash flow jumped to £262 million, net debt fell to £329 million, and management says FY27 expectations are unchanged.
The problem is the Type 31 frigate contract. A £140 million non-recurring charge has dragged reported underlying operating profit down to £293 million from what would otherwise have been £433 million. So this is a classic mixed update – a strong business underneath, with one sizeable contract issue landing heavily on the numbers.
Babcock FY26 key figures: revenue up, cash flow up, margin hit by Type 31 charge
| Metric | FY26 | FY25 |
|---|---|---|
| Contract backlog | £9.6 billion | £10.4 billion |
| Revenue | £5,273 million | £4,831 million |
| Underlying operating profit | £293 million | £363 million |
| Underlying operating profit excluding Type 31 charge | £433 million | £363 million |
| Underlying operating margin | 5.7% | 7.5% |
| Underlying operating margin excluding Type 31 charge | 8.2% | 7.5% |
| Underlying basic EPS | 39.6p | 50.3p |
| Underlying basic EPS excluding Type 31 charge | 60.5p | 50.3p |
| Underlying free cash flow | £262 million | £153 million |
| Net debt | £329 million | £373 million |
There is an important split here. Including the Type 31 charge, profit and margin look weaker year-on-year. Excluding it, Babcock actually had a very strong year and beat its own FY26 margin target of 8.0%, delivering 8.2%.
What the £140 million Type 31 charge actually means for Babcock investors
Type 31 is Babcock’s five-ship frigate programme. The company says that as ship one moved into the later outfitting and commissioning stages, it found higher-than-expected levels of rework caused by design changes and the long-term effects of earlier out-of-sequence build activity.
In plain English, this means some work has had to be redone, and doing that late in the build process is more expensive and more disruptive than fixing it earlier. Babcock has therefore updated its estimate of what it will cost to complete the programme and booked a £140 million charge in FY26.
Of that £140 million, around £100 million is expected to be recognised as a revenue reversal in FY26. The rest increases the contract loss provision, which is an accounting provision for expected losses on the contract. The cash impact will come over the remainder of the programme rather than all at once this year.
This matters because defence contracts can be long dated and technically messy. When a company has to re-estimate costs on a major fixed-price programme, investors naturally worry about whether this is a one-off or a sign of deeper execution risk. Babcock is clearly trying to frame this as specific to Type 31 rather than a wider problem.
Babcock divisional performance: Nuclear and Aviation did the heavy lifting
Nuclear delivered the standout performance
Nuclear revenue increased 14% to £2,070 million, while underlying operating profit rose 23% to £197 million. Margin improved to 9.5%, which is notable because it meets the group’s medium-term target of at least 9%.
That is a big positive. Nuclear is increasingly central to the Babcock story, and this update shows the division is growing nicely while improving quality of earnings.
Marine was solid underneath, but Type 31 swamped the reported number
Marine revenue increased 8% to £1,687 million before the roughly £100 million revenue reversal linked to Type 31. Excluding the charge, underlying operating profit rose to £110 million and margin was 6.5%.
Including the charge, Marine swung to an underlying operating loss of £30 million, with a margin of negative 1.9%. So the core performance was decent, but the contract problem completely dominated what investors will focus on.
Land and Aviation also improved
Land revenue fell 3% to £1,084 million, but profit still rose 10% to £95 million and margin improved to 8.8%. That tells you the mix shifted towards better-quality defence work, even as some civil activity remained softer.
Aviation had a particularly strong year. Revenue surged 34% to £431 million and underlying operating profit increased 52% to £31 million, helped by the Mentor 2 programme in France, the British Columbia helicopter emergency services contract in Canada, and higher UK military support activity.
Babcock share buyback and balance sheet: why the new £200 million programme matters
Babcock completed its previous £200 million share buyback in April 2026 and has now announced another £200 million programme. A buyback is when a company purchases its own shares, usually supporting earnings per share and signalling confidence in cash generation.
This is only possible because the balance sheet has improved. Net debt fell to £329 million, and on a covenant basis – the measure lenders use in financing agreements – net debt to EBITDA was just 0.2x, down from 0.3x. Net debt excluding leases was only £23 million.
That is a strong position. My view is that the new buyback softens the blow from Type 31 because it tells the market management still sees the wider business as financially robust.
FY27 guidance unchanged: the market will like that, but trust now matters more
The company says FY27 expectations are unchanged, with around 70% of revenue already under contract at 1 April 2026. That gives useful visibility, especially for a business built around long-term defence and nuclear contracts.
Babcock also repeated its medium-term guidance for average revenue growth of mid-single digit, underlying operating margin of at least 9%, and average underlying operating cash conversion of at least 80%. Cash conversion measures how much accounting profit turns into actual cash, and Babcock says FY26 delivered 85% excluding the Type 31 charge impact on operating profit.
That is reassuring, but investors will still want proof. After a contract write-down like this, management has to rebuild confidence by showing no further nasty surprises emerge from Type 31.
Strategic contract wins show Babcock still has momentum beyond the Type 31 issue
- Indonesia – a Letter of Intent was signed for the sale of a further two Arrowhead 140 frigate licences, expected to be delivered in early FY27.
- US Virginia Class submarine build programme – Babcock is now authorised, through its partnership with HII, to manufacture and build complex submarine assemblies at Rosyth.
- UK and Albania light utility vehicle orders – including 270 units for the British Army’s 11 Brigade.
- FMSP follow-on work – a six-month UK Ministry of Defence bridging agreement for nuclear submarine fleet support, plus a two-year extension for surface ship fleet maintenance and infrastructure support.
- Small Modular Reactor opportunity – after year end, Litmus Nuclear was selected for an Owner’s Engineer contract worth up to £300 million over 14 years.
These announcements matter because they show the underlying demand backdrop remains strong. Babcock is exposed to defence and energy security, two areas where government spending remains strategically important.
My verdict on the Babcock FY26 update: good business, bad contract, unchanged investment case – for now
This is not a clean update, but it is better than a superficial glance might suggest. Operationally, Babcock had a strong FY26. Revenue growth was good, cash flow was strong, debt fell, Nuclear was excellent, Aviation was impressive, and management felt confident enough to launch another £200 million buyback.
The negative is obvious. A £140 million Type 31 charge is large, and contract re-estimates always dent market confidence. It has also pushed the audited full-year results back to late June, which is understandable but never ideal.
So my read is balanced. The core investment case looks intact because FY27 guidance is unchanged and the wider business is performing well. But the market will now watch Type 31 like a hawk, because if this really is a contained one-off, Babcock can move on. If not, the quality of those attractive underlying numbers will be questioned.
