TNS Completes Acquisition of BT Radianz

WHY THIS MATTERS:
Financial markets connectivity is becoming increasingly strategic as trading venues fragment, data volumes rise and resilience expectations intensify. Institutions now rely on highly secure, low-latency networks not just for execution, but for continuous access to market data, applications and counterparties across regions. This acquisition reflects a broader consolidation trend in financial market infrastructure, as providers seek scale, global reach and diversified network paths to support always-on markets. Combining long-established connectivity platforms responds to client demand for both performance and redundancy—particularly as operational resilience and regulatory scrutiny move higher up the agenda. In an environment where downtime carries material risk, connectivity is no longer a utility; it is core market infrastructure.

Transaction Network Services (TNS) has completed its acquisition of BT’s Radianz business. The deal brings together two long-standing providers of financial markets connectivity and expands access, reach and service capability for institutions worldwide. 

Radianz has connected the global financial community for more than 20 years, providing secure access to trading venues, market data, applications, and counterparties. The business will now form part of TNS’s global Financial Markets offering. 

“Today marks an important milestone for TNS and our clients as we combine the strengths of two established leaders in financial connectivity,” said Tom Lazenga, General Manager, TNS Financial Markets. “We look forward to delivering expanded access to markets, counterparties and applications, while maintaining the network and platform diversity that institutions rely on for resilience and choice.”  

Radianz, known for its secure network linking thousands of market participants and financial applications, complements TNS’s ultra-low-latency trading, market data and hosting capabilities. 

Phil Swindle, Managing Director, Radianz, said: “Radianz has a long track record of supporting mission-critical financial communications. Joining TNS brings complementary strengths and continued investment for customers.”

TNS is looking forward to welcoming the Radianz clients, employees, and partners into its global ecosystem. Lazenga added: “We are dedicated to providing best in class services through our combined businesses and investing in our joint future together.”

FF NEWS TAKE:
This deal strengthens TNS’s position as a global connectivity provider for financial markets. The key focus now will be integration—ensuring clients retain choice and resilience while benefiting from expanded reach. Watch for increased investment in network diversity and latency-sensitive services as competition in market connectivity intensifies.
