New £50m Annex Fund raised by Aliter

Supports further growth at TXP and Serbus

Aliter has launched a new £50 million Annex Fund, to support further growth at two of its established technology platforms, TXP and Serbus.

TXP (Technology x People) is the systems integrator focused on technology consulting, development and resourcing and Serbus delivers specialist, secure Critical National Infrastructure (CNI) networking and communications solutions.

Aliter first invested in both businesses in 2022, supporting three further add-on acquisitions at each company and their rebranding as TXP and Serbus in 2025 and 2026 respectively.

Sitting alongside Aliter’s existing £134m fund, Aliter Capital II, the new £50m Annex Fund has been backed exclusively by existing institutional investors, providing dedicated capital to support the next phase of growth in both businesses, while enabling Aliter to retain its existing interests.

Aliter partner Greig Brown said: “In establishing the Annex Fund, we very much welcome the strong support shown by the existing Aliter Capital II investors participating in the Annex Fund. TXP and Serbus have great management teams, with a clarity of vision and exciting plans for future growth. We look forward to extending our close working relationship with them and the new funds will facilitate a wider range of strategic add-on acquisitions.”

Simon Fieldhouse, Group CEO, Serbus said: “As threats to the UK’s critical national infrastructure continue to evolve, Serbus is building a sovereign, market leading group with security in its DNA. Through targeted acquisitions and investment, we are strengthening our ability to connect and protect the nation’s most critical services and infrastructure.”

John Antunes, CEO at TXP, said: “We’re delighted to have the continued backing of Aliter and its investors as we enter the next phase of TXP’s growth. It gives us further firepower to accelerate our buy-and-build ambitions, broaden our capabilities and continue building a differentiated technology business that delivers greater value for our clients.”
