Cogent Communications faces securities fraud class action lawsuit
SAN FRANCISCO, Sept. 1, 2026 /CourierPR/ -- Cogent Communications Holdings, Inc. (NASDAQ: CCOI) investors are facing a significant legal challenge after a national plaintiffs' rights law firm, Hagens Berman Sobol Shapiro LLP, filed a securities fraud class action. The lawsuit, which follows a series of financial disclosures that highlighted ongoing operational contractions, is set to reach a critical milestone on September 21, 2026, with the lead plaintiff deadline fast approaching.
In a press release, Hagens Berman notified investors who suffered substantial losses to submit their claims now. The firm's latest alert comes after Cogent's Q2 2026 financial report, which revealed a persistent softening in service revenue and a continued decline in off-net revenue. These results mirror a broader pattern of financial challenges that have drawn increased scrutiny from the investment community.
According to the lawsuit, the case centers on Cogent's claims regarding its optical wavelength "backlog." The complaint alleges that the company misrepresented customer demand for its optical wavelength services and the nature of its backlog. Specifically, it is argued that the wavelength backlog was an illusory measure unlikely to convert into revenue, and that many customers in the backlog were unable or unwilling to accept delivery, even if Cogent was in a position to provision the wavelengths.
Hagens Berman's investigation into Cogent's disclosures began to gain traction in February 2025. That month, Cogent reported disappointing Q4 and FY 2024 financial results, citing a 20% sequential decline in its backlog and the removal of 1,500 orders due to their age. The market's response was swift, sending Cogent's stock price plummeting.
Further evidence emerged in May 2025, when Cogent reported Q1 2025 results, stating that it had more installation capacity than orders ready to be installed. Management conceded that "the majority of that funnel fell out," mirroring the market's skepticism. The company's decision to cease providing backlog data in February 2026, following Q4 and FY 2025 results, and the subsequent steep decline in stock price further underscored the growing concerns.
On May 4, 2026, Cogent reported Q1 2026 results, which again disappointed on wavelength revenue and customer connections. Management acknowledged that "customers are pushing out their acceptance" and noted that "we actually provisioned more wavelengths in the quarter than we did in the previous quarter, but the customers did not accept them."
Reed Kathrein, a partner leading Hagens Berman's investigation, stated, "We're focused on whether Cogent and its management intentionally promoted wavelength backlog and funnel as a way to misrepresent both the company's actual ability to convert them to earned revenues and the real company-centric wavelength demand."
Investors who believe they have suffered substantial losses are encouraged to submit their claims now. The firm is also seeking whistleblowers with non-public information regarding Cogent. Under the SEC Whistleblower program, individuals who provide original information may be eligible for rewards up to 30 percent of any successful recovery made by the SEC.
