GTT Communications today said it reached a deal to acquire Dutch telecommunications and IT provider KPN International for $56 million in cash. KPN International is a division of KPN N.V.

The purchase, which includes KPN International’s long-haul fiber routes and metro rings in London, Amsterdam, Paris, and Frankfurt, Germany and will expand GTT’s network across 21 European countries. It also makes GTT the preferred international network supplier for an additional 400 of KPN’s enterprise and carrier customers.

KPN International’s global sales, operations, service delivery, and client service organization will join GTT after the transaction closes, which the companies expect to happen in the third quarter of 2019.

“The acquisition of KPN International deepens our market presence in the European region,” said Rick Calder, GTT president and CEO. “The world-class resources contributed from this acquisition, including a highly experienced team, international network assets and a deep roster of multinational clients, will help us deliver on our purpose of connecting people across organizations around the world and to every application in the cloud.”

The deal also follows several other networking and carrier acquisitions that GTT made over the last two years.

In January 2018 it acquired Amsterdam-based network connectivity provider Custom Connect to extend the reach of its internet backbone. In March, it acquired Toronto-based Accelerated Connections, which provides managed networking, voice-over-IP (VoIP), and colocation services. This expanded GTT’s network footprint in Canada. In May it bought London-based Interoute, which operated of one of Europe’s largest independent fiber networks and cloud networking platforms, for $2.3 billion in cash. And in October it purchased North Carolina-based communication services provider Access Point for $40 million.

GTT also acquired Global Capacity for $100 million in 2017 to boost its SD-WAN for enterprise customers.
