Investors who purchased Cogent Communications Holdings, Inc. shares between Feb. 29, 2024 and May 1, 2026 have until Sept. 21, 2026 to seek appointment as lead plaintiff in a proposed securities class action pending in the United States District Court for the District of Columbia. The case is City of Southfield Fire and Police Retirement System v. Cogent Communications Holdings, Inc., No. 26-cv-02609. The complaint alleges Cogent and certain executives misrepresented demand for optical wavelength services, the quality and convertibility of its backlog, its revenue and margin outlook, the sustainability of its dividend policy, and undisclosed risks that Founder, CEO and Chairman David Schaeffer could be forced to sell large amounts of pledged stock. The allegations have not been proven in court.
