About Serco Group plc

Serco is an international provider of critical services to governments, operating in areas such as defence, justice, immigration, transport and citizen services. It employs around 50,000 colleagues across the UK, Europe, North America, Asia Pacific and the Middle East.

The group focuses on growth, performance and Capital discipline across its portfolio.

Defence

Following significant order intake in 2025, Defence performed particularly well, delivering organic revenue growth of 10% in the half. Around two thirds of 2025 awards were in defence.

The group's pipeline stands at £12.5bn, providing visibility on future bidding opportunities.

Guidance

The group reiterated full-year guidance of revenue of around £5.0bn, underlying operating profit of around £300m and free Cash Flow of around £160m. First-half free cash flow was £65m, and the group is on track for full-year trading cash conversion of at least 80%.

As usual, the second-half margin is expected to moderate from the first half, while still improving on the second half of 2025.

Order Intake and Regions

Order intake was £2.5bn with a book-to-bill ratio of 100%. In Asia Pacific, order intake exceeded £500m earlier in the year, including five-year extensions for Acacia Prison and Adelaide Remand Centre.

Management noted contract mobilisations in the UK and Australia and an anticipated improvement in the North America procurement environment.

FY25 Reference Points

For 2025, revenue was £4.9bn with a margin of 5.6%, order intake was £5.5bn with a book-to-bill of 114% and the order book was £14.5bn. Trading cash conversion was 112%.

The group completed a £50m buyback in 2025 and announced a new £75m programme in March 2026, bringing total Buybacks since 2021 to £465m.

Understanding Book-to-Bill and Margin

Book-to-bill compares the value of new orders with revenue recognised, so a ratio of 100% means new orders matched revenue. Underlying operating margin shows operating profit as a share of revenue.

Trading cash conversion shows how much of operating profit is converted into cash.

Why the Update Matters for the Sector

Outsourcing groups are followed for contract visibility, margin delivery and cash generation. Serco's results show how a portfolio can balance defence growth with long-running public service contracts.

A multi-year order book gives investors a view of future revenue timing.

Services Portfolio

Serco delivers services under long-running government contracts, including defence support, justice and immigration services, transport operations and citizen-facing services. The group says its customers value reliability and delivery on critical missions.

Contract terms often run for several years, with renewals and extensions forming an important part of order intake.

Key Growth Catalysts

Defence growth, a large pipeline, margin progression and increased buybacks give the group several reference points. Contract mobilisations are expected to support second-half activity.

Factors to Monitor

Procurement timing can vary between regions, and contract mobilisations require careful delivery. Currency movements also affect reported figures.
