Serco Group plc: history, ownership, mission, how it works & makes money

From its origins as R.C.A Limited in 1929 through a 1987 rebrand to Serco Group plc and expansion into transport, health and justice-winning high-profile contracts like the London Cycle Hire Scheme in 2010-Serco has reinvented itself after a 2014 restructuring and, with the 2025 acquisition of Northrop Grumman's MT&S business, dramatically strengthened its U.S. defence footprint; today the FTSE-listed SRP reports revenues of £4.8 billion (late 2025), a market capitalisation near £3.5 billion (Dec 2025), and a diverse shareholder base including BlackRock and Vanguard alongside a Board led by Chairman John Rishton and CEO Anthony Kirby-backed by a December 2025 £50 million buyback-while operating across four regions and five core sectors (Defence, Justice & Immigration, Transport, Health & FM, Citizen Services), employing over 50,000 people, sustaining free cash flow of £228 million in 2024, an order book of £13.3 billion and an £11.2 billion pipeline, and projecting underlying operating profit around £270 million for 2025 as MT&S is expected to add roughly £2 billion of annual revenue to Serco's long-term, contract-driven model grounded in values of Trust, Care, Innovation and Pride and a 'Zero Harm' safety vision
