The complaint alleges that Cogent Communications misled investors by inflating its optical wavelength backlog, claiming orders that were unlikely to materialize or involve customers unable to accept delivery. These disclosures reportedly obscured the company’s inability to meet revenue and margin targets, while raising questions about the sustainability of its dividend policy. The lawsuit also highlights concerns regarding high-risk stock pledging activities by executive David Schaeffer, which allegedly created undisclosed risks for shareholders.

The market reacted sharply to these revelations, particularly following a May 4, 2026, disclosure of ongoing wavelength underperformance. Shares of Cogent fell $6.79, or 29%, to close at $16.37 that day. Investors who purchased common stock during the specified class period may now seek to be appointed as lead plaintiff. The deadline to file for this status is September 21, 2026. The law firm Kessler Topaz Meltzer & Check, LLP is currently offering case evaluations for those affected by the stock’s decline, operating on a contingency fee basis.
