CASE ALLEGATIONS : Cogent is a global facilities-based provider of low-cost, high-speed internet access, private network services, optical wavelength and transport services, and data center colocation space and power. The Cogent class action lawsuit alleges that defendants throughout the Class Period made materially false and misleading statements because they failed to disclose the following adverse facts pertaining to Cogent's business, operations, and financial condition, which were known to or recklessly disregarded by defendants: (i) that the vast majority of the purported orders in Cogent's optical wavelength "backlog" were unlikely to ever result in a paid order; (ii) 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; (iii) that, as a result of (i)-(ii) above, defendants had materially misrepresented customer demand for Cogent's optical wavelength services and the nature of Cogent's purported "backlog" of wavelength orders; (iv) that, as a result of (i)-(iii) above, Cogent was not on track to achieve its revenue and margin targets and such targets lacked a reasonable basis in objective fact; (v) that Cogent did not have the financial capacity or business fundamentals to maintain its long-standing dividend policy; and (vi) that there was a material, undisclosed risk that defendant David 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.

Management explained that Cogent had removed 1,500 orders from its backlog because many orders were more than a year old. Additionally, growth in wavelength connections slowed from 287 net additions in third quarter 2024 to 77 net additions in fourth quarter 2024. On this news, the price of Cogen stock fell 10%. Then, on May 8, 2025, Cogent announced its first quarter 2025 financial results, reporting that revenues in the wavelength business were lower than expected, which had negatively impacted Cogent's earnings, margins, and leverage. Although Cogent had expanded its offering of optical wavelength services to over 880 data centers across North America, wavelength revenues only increased by $200,000 from fourth quarter 2024. Executives further revealed that Cogent now had the capacity to provision 500 orders per month but only expected to be able to convert 5% of its 3,400 order backlog. On this...
