CCOI SHAREHOLDER ACTION REMINDER: Faruqi & Faruqi, LLP Reminds Cogent Investors of Securities Class Action Lawsuit Deadline on September 21, 2026

Faruqi & Faruqi, LLP is investigating potential claims against Cogent Communications Holdings, Inc. (NASDAQ: CCOI) and reminds investors of the September 21, 2026 deadline to seek the role of lead plaintiff in a federal securities class action that has been filed against the Company. The complaint alleges that the Company and its executives violated federal securities laws by making false and/or misleading statements and/or failing to disclose that: (a) that the vast majority of the purported orders in Cogent's optical wavelength "backlog" were unlikely to ever result in a paid order; (b) that large quantities of the customers in Cogent's purported optical wavelength "backlog" were unable or unwilling to accept delivery even if Cogent was in a position to provision the wavelength in a timely manner; (c) that, as a result of (a)-(b) above, defendants had materially misrepresented customer demand for Cogent's optical wavelength services and the nature of the Company's purported "backlog" of wavelength orders; (d) that, as a result of (a)-(c) above, Cogent was not on track to achieve its revenue and margin targets and such targets lacked a reasonable basis in objective fact; (e) that Cogent did not have the financial capacity or business fundamentals to maintain its long-standing dividend policy; and (f) that there was a material, undisclosed risk that defendant Schaeffer would be forced to sell vast quantities of Cogent stock as a result of his high-risk pledging activities, thereby further depressing the price of Cogent stock in the event the truth regarding Cogent's "backlog," demand issues, and financial position were ever revealed.
