Cogent Communications Holdings Inc

Cogent Communications Holdings, Inc. is a multinational, Tier 1 facilities-based Internet service provider. It sells high-speed Internet access, Ethernet transport, optical wavelength, optical transport and colocation services to businesses, over an all-optical IP network backbone spanning 309 markets globally.

Revenue comes from four service types:
- **On-net services:** delivered to buildings physically connected to Cogent's network.
- **Off-net services:** use other carriers' last-mile facilities to reach customer premises.
- **Optical wavelength services:** offered in 1,151 locations across the U.S., Mexico and Canada.
- **Non-core legacy services:** inherited through acquisitions and supported but not actively sold.

The company also reports revenue by customer type: corporate, net-centric and enterprise.

Its 2023 acquisition of Sprint's U.S. long-haul fiber network (the Wireline Business) from T-Mobile enabled the wavelength business. It also brought a T-Mobile IP Transit Services Agreement worth $700 million in aggregate and technical buildings that Cogent converted into Cogent Data Centers and Cogent Edge Data Centers.

Cogent has been monetizing real estate, including selling ten owned data centers in Q2 2026 and signing letters of intent to sell four more. It is also repurchasing debt, holds secured IPv4 notes backed by its IPv4 address portfolio, and suspended its dividend in November 2026. Updated Nov 5, 2026
