CCOI DEADLINE NOTICE: Faruqi & Faruqi, LLP Reminds Cogent Investors of Securities Class Action Lawsuit Deadline on September 21, 2026

Faruqi & Faruqi, LLP , a leading national securities law firm, is investigating potential claims against Cogent Communications Holdings, Inc. ("Cogent" or the "Company") (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.

Any member of the putative class may move the Court to serve as lead plaintiff through counsel of their choice, or may choose to do nothing and remain an absent class member. Your ability to share in any recovery is not affected by the decision to serve as a lead plaintiff or not.

Faruqi & Faruqi, LLP also encourages anyone with information regarding Cogent's conduct to contact the firm, including whistleblowers, former employees, shareholders and others.
