Why is Cogent Being Sued for Securities Fraud?

Cogent is a global facilities-based provider of internet access, private network services, optical wavelength and transport services, and data center colocation space and power.

The lawsuit alleges that Cogent overstated demand for its wavelength business, repeatedly touting a large backlog of customer orders and reassuring investors that it could meet its financial targets and maintain its dividend.

In truth, as alleged, Cogent’s backlog was unlikely to become paid orders and many customers were not ready to accept delivery of products, putting Cogent’s dividend at risk.

Why did Cogent’s Stock Drop?

On February 27, 2025, Cogent reported fourth quarter and full year 2024 results showing that wavelength revenue was only $7 million and that its backlog had declined from 3,400 to 2,700 unique wavelengths. Following this news, Cogent’s stock price declined $7.65 per share, or 10%.

On May 8, 2025, Cogent reported lower-than-expected wavelength revenue, acknowledged that many wavelength customers were not ready to accept delivery, and disclosed that it expected to convert only a small percentage of its backlog each month. Following this news, Cogent’s stock price declined $3.91 per share, or 7%.

On August 7, 2025, Cogent again reported disappointing wavelength results, including only 147 net wavelength connection additions, and continued customer acceptance issues. Following this news, Cogent’s stock price declined $8.54 per share, or 19%, on August 7, 2025, and declined another $4.72 per share, or 13%, on August 8, 2025.

On November 6, 2025, Cogent reduced its quarterly dividend from $1.015 per share to $0.02 per share, a 98% reduction. Following this news, Cogent’s stock price declined from $38.30 per share on November 5, 2025 to $16.68 per share on November 13, 2025, a total decline of $21.62 per share, or 56%.

Finally, on May 4, 2026, Cogent disclosed further wavelength underperformance and customer acceptance delays. Following this news, Cogent’s stock price declined $6.79 per share, or 29%, to close at $16.37 per share on May 4, 2026.
