BT completes sale of Radianz to TNS

BT completed the sale of its Radianz business to Transaction Network Services (TNS), a transaction that the company said supported a narrower focus on core products and services within BT International. The transfer followed earlier public notice of the deal and regulatory clearance.

The transaction was first announced on 2 September 2025 and later cleared by the relevant regulatory authorities; BT described the move as part of a sharpened focus on secure multi-cloud connectivity within its international operations.

Launched over 20 years ago, Radianz provides financial information exchange networks and connects a global community of brokers, institutions, exchanges and clearing and settlement houses to the thousands of applications and services they need for the everyday running of the world’s capital markets. TNS is a global provider of ultra-low latency trading infrastructure, connectivity and market data services.

The sale was completed and advisers were named: Evercore served as financial advisers to TNS and Jones Day served as legal advisers to TNS, while Citi served as financial advisers to BT and Bryan Cave Leighton Paisner served as legal advisers to BT.

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.”

The companies described plans for TNS to continue to deliver service to customers under the terms of the completed transaction.
