According to the Complaint, the Company made false and misleading statements to the market. GTT experienced significant delays in integrating Interoute Communications Holdings S.A.s (“Interoute”) systems and legacy processes into the Companys client management database. Interoute had made selling cloud services a strategic priority, but a considerable percentage of Interoute sales reps were not able to effectively sell GTTs cloud networking services. In fact, Interoute had allowed underperforming sales reps to remain on staff. Based on these facts, the Companys public statements were false and materially misleading throughout the class period. When the market learned the truth about GTT, investors suffered damages.

Join the case to recover your losses.
