Cogent Communications Holdings, Inc. reports on its business for the year ended December 31, 2025, highlighting a global, facilities-based Internet and optical transport platform centered on low-cost, high-speed connectivity.
The company now operates through Cogent Infrastructure and Cogent Communications Group, following the acquisition of Sprint’s long-haul fiber assets (the Cogent Fiber Business). This added approximately 23,500 route miles of U.S. fiber, 1.9 million square feet of facilities and 9.9 million IPv4 addresses, which have been partially transferred into its legacy operating structure.
Cogent funds its network and data center expansion with a mix of unsecured and secured debt, including $750.0 million of 7.00% senior unsecured notes due 2027, $600.0 million of 6.50% senior secured notes due 2032, and $380.4 million of secured IPv4 address revenue notes. Strategy focuses on growing corporate, net-centric and large enterprise customers, expanding wavelength services across 1,068 wave-enabled locations, leasing IPv4 addresses (15.3 million of roughly 38 million owned as of December 31, 2025) and monetizing surplus data center and IP resources.
