BT Agrees Deal to Sell its Radianz Business to Transaction Network Services

Telecoms giant BT has today announced that their Radianz unit, which is a global network and connectivity platform for the financial services industry that generated revenues of approx. £142m during 2024/25, is to be sold to Transaction Network Services (TNS) – a provider of ultra-low latency trading infrastructure – for an undisclosed sum.

The planned transaction aligns with BT’s strategy to withdraw from its global operations and become more of a UK-focused “national champion“, while also exploring options to “optimise its international business“.

The transaction, assuming no unexpected obstacles arise during the process, is expected to complete during the first half of 2026, subject to customary closing conditions, including regulatory clearance.

Bas Burger, CEO of BT International, said:

“Today’s announcement is another key milestone in focusing our international business on what it does best: providing secure multi-cloud connectivity to large organisations globally. Our Radianz business unit will enter a new era with TNS and we are confident that TNS will continue to deliver exceptional service to customers.”

Tom Lazenga, General Manager of TNS Financial Markets, said:

“This is an exciting development for clients of both TNS and Radianz who will now have access to the combined suite of services in addition to our investments in new capabilities. With a large global network of financial endpoints and our industry leading low latency platform, today’s news firmly cements TNS as the premier partner serving financial market participants globally.”
