Cogent Communications shares plunge 29% after revenue drop and customer losses

Cogent Communications' stock fell sharply by 29.32% on May 4, 2026, following a report that its service revenue declined by 3.2% year-over-year for the first quarter ending March 31, 2026. The company attributed the revenue drop partly to the cancellation of low-margin and non-core customers acquired through its Cogent Fiber Business. This significant decline has prompted Kehoe Law Firm to investigate potential securities claims on behalf of investors who suffered financial losses. Investors are encouraged to seek legal advice regarding possible claims against the company.
