Is CCOI a Buy as Margins Improve but Refinancing Risks Stay High?
Cogent Communications (CCOI) trades near a five-year low valuation with a 1.14 EV-to-sales ratio. Q2 2026 service revenues fell 4.3% YoY to $235.6M, but higher-margin on-net and wavelength services grew, improving gross and EBITDA margins. The company faces refinancing risks with $750M in notes maturing in 2027 and high leverage at 6.23x. Operating cash flow improved but remains dependent on T-Mobile payments. CCOI has a Zacks Rank #2 (Buy) with mixed scores.
