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.
Cogent Communications Holdings, Inc. reported lower service revenue but stronger profitability for Q4 and full year 2025.

Full-year 2025 service revenue was $975.8 million versus $1,036.1 million in 2024, with constant-currency revenue down 6.3%.
Profitability improved markedly. GAAP gross profit rose to $170.6 million in 2025, with GAAP gross margin increasing from 9.3% to 17.5%. Non‑GAAP gross profit reached $442.7 million and non‑GAAP gross margin improved to 45.4%. EBITDA increased from $122.8 million in 2024 to $192.8 million in 2025, and Q4 2025 EBITDA margin was 21.5%.
Despite these gains, Cogent posted a 2025 net loss of $182.2 million, or $3.80 per share, compared with a $204.1 million loss in 2024. Net cash used in operating activities was $10.6 million for 2025. Leverage remained high, with a year‑end 2025 net leverage ratio of 7.34x and 6.64x when adjusted for amounts due from T‑Mobile.
The business mix continued to shift. Wavelength revenue grew to $38.5 million in 2025, more than double 2024, and wavelength customer connections increased sharply to 2,064 as of December 31, 2025. Off‑net revenue fell 12.5% to $397.5 million and non‑core revenue dropped to $8.3 million, reflecting the phase‑out of legacy services.
Cogent’s IP Transit Services Agreement with T‑Mobile remained an important cash contributor. Cash payments under this agreement totaled $100.0 million in 2025, down from $204.2 million in 2024. Revenue recognized under a related commercial agreement with T‑Mobile was $2.6 million for 2025.
