About the Lawsuit

Ribbon and certain of its executives are charged with failing to disclose material information during the Class Period, violating federal securities laws. 

On March 24, 2015, Ribbon, formerly Sonus Networks, Inc., disclosed dismal results for the first quarter of 2015, including revenue of only $47-$50 million, approximately $24-$30 million lower than expected, and a $0.29-$0.34 loss in non-GAAP earnings-per-share, lower than the $0.03 gain forecasted.

On this news, the price of Ribbon’s shares plummeted $4.46 per share, from $13.16 to $8.70 per share, a loss of over 33%.

The case is Miller v. Sonus Networks, Inc., et al., 18-cv-12344.
