Babcock International Group has reported a year of strong underlying financial performance for FY26, with revenue up 10% to £5.27 billion and underlying operating profit – excluding a significant one-off charge – rising 19% to £433 million.
The headline figures, however, are dominated by a £140 million charge on the troubled Type 31 frigate programme, which has overshadowed what would otherwise have been a landmark year for the company.
The results, based on unaudited management accounts, confirm that Babcock’s nuclear and aviation divisions delivered exceptional growth, while the Marine sector – home to the Type 31 programme – bore the full weight of the charge.
The Type 31 Problem
The £140 million charge on the Type 31 Arrowhead 140 frigate programme is the standout issue in Babcock’s results and will draw the most attention from the defence procurement community.
The programme covers five ships being built at Rosyth. The first two have been floated off, the keel of ship three has been laid, and the steel-cutting ceremony for ship four has taken place. But as structural completion of ship one moves into outfitting and commissioning – historically the most labour-intensive and complex phase of any warship build – Babcock has encountered higher than expected levels of rework driven by design changes and the long-term consequences of out-of-sequence build activity earlier in the programme.
The company is candid about the mechanics of the problem: rework events of this kind are not entirely unexpected in complex warship programmes, but their concentration in the later, more costly stages of completion has amplified their financial impact. Ship two, close behind ship one in the build sequence, has also been affected by design-related rework. Ships three and four, still in early construction, are described as comparatively less exposed.
An engineering maturity review has been completed and financial estimates to complete the programme have been revised upward, covering both production costs and increased risk contingency. The £140 million charge is fully recognised in FY26, though the cash costs will be incurred over the remainder of the programme.
For the Royal Navy and MoD, the charge raises familiar questions about risk allocation, design maturity and build sequencing in major warship programmes – questions that will resonate with anyone tracking the UK’s broader naval shipbuilding ambitions.
Where Babcock Is Growing
Strip out the Type 31 charge and the underlying business tells a markedly different story.
Nuclear revenue grew 14% to £2.07 billion, driven by an 18% increase in Cavendish Nuclear and higher submarine support activity. Underlying operating margin in the Nuclear division reached 9.5% – hitting Babcock’s own medium-term group target a year early. The division’s performance reflects the sustained and growing demand flowing from the UK’s Defence Nuclear Enterprise, including submarine support, nuclear infrastructure and, increasingly, civil nuclear.
Aviation revenue grew 34% to £431 million, driven by the ramp-up of the Mentor 2 programme in France, the British Columbia helicopter emergency services contract in Canada, and expanded scope in UK military support contracts – a division that has quietly become one of Babcock’s strongest performers.
Marine revenue, excluding the Type 31 charge, grew 8% to £1.69 billion, supported by higher volumes in the LGE business and growth in the Skynet programme.
Strategic Wins Worth Watching
Beyond the financials, Babcock has secured several strategically significant contracts and partnerships that point to its direction of travel.
In Indonesia, the company has signed a Letter of Intent for two further Arrowhead 140 frigate licences under its £4 billion Maritime Partnerships Programme – a significant export win that will be closely watched given the Type 31 difficulties at home. Separately, through an expanded partnership with HII, Babcock is now authorised to manufacture complex submarine assemblies at Rosyth for the US Virginia Class Block VI fast-attack submarine programme – a notable step into the AUKUS-adjacent industrial base.
On the civil nuclear side, the Litmus Nuclear joint venture – formed between Cavendish Nuclear and Amentum – was selected by Great British Energy Nuclear as Owner’s Engineer for the UK’s first Small Modular Reactor project at Wylfa in North Wales. The contract is worth up to £300 million over 14 years, giving Babcock a leading position in what could become one of the most significant infrastructure programmes of the next two decades.
Babcock also agreed a six-month bridging agreement with the MoD to maintain continuity of nuclear submarine fleet support and naval base management services, alongside a two-year extension for surface ship fleet maintenance – contracts that underpin revenue visibility going into FY27.
Outlook
Babcock says FY27 expectations are unchanged, with around 70% of anticipated revenue already under contract as of 1 April 2026. Medium-term guidance points to mid-single digit revenue growth, underlying operating margins of at least 9%, and cash conversion of at least 80%.
Incoming CEO Harry Holt – who moves from leading the Nuclear division and takes the top role formally in June 2026 – inherits a business with genuine strategic momentum, a strong balance sheet, and a net debt position reduced to £329 million. His immediate challenge will be managing the Type 31 programme through its most complex remaining phase while sustaining the growth trajectory that the nuclear and aviation divisions have delivered.
A new £200 million share buyback programme has been announced, reflecting the board’s confidence in the group’s underlying financial position.
