Kessler Topaz Meltzer & Check, LLP Announces Shareholder Class Action Against Sonus Networks, Inc. -- SONS

May 18, 2015, 10:30 ET from Kessler Topaz Meltzer & Check, LLP

RADNOR, Pa., May 18, 2015 /PRNewswire/ -- The law firm of Kessler Topaz Meltzer & Check, LLP announces that a shareholder class action has been filed against Sonus Networks, Inc. (Nasdaq: SONS) ("Sonus" or the "Company") on behalf of purchasers of the Company's common stock between October 23, 2014 and March 24, 2015, inclusive (the "Class Period").

On March 24, 2015, Sonus disclosed that it "no longer expects to receive certain orders … that had been expected to be received at the back end of the first quarter," and that it was substantially lowering its first quarter and expected full-year 2015 financial guidance estimates.  On this news, shares of Sonus' common stock declined $4.46 per share, or nearly 34 percent, to close on March 24, 2015 at $8.70 per share.

The complaint filed in the action alleges that, throughout the Class Period, Sonus and certain of its executive officers made a series of false and misleading statements.  Specifically, the complaint alleges that the defendants failed to disclose that: (1) the Company would be unable to close certain orders in the first quarter of 2015; and (2) the Company was experiencing longer decision cycles from its customers.  For additional information about the lawsuit, or to request information about the action, please visit

Members of the class may, no later than June 5, 2015, petition the Court for appointment as a lead plaintiff of the class.  A lead plaintiff is a representative party who acts on behalf of all class members in directing the litigation against Sonus.  In order to be appointed as a lead plaintiff, the Court must determine that the class member's claim is typical of the claims of other class members, and that the class member will adequately represent the class in the action.  Your ability to share in any recovery is not affected by the decision of whether or not to serve as a lead plaintiff.  Any member of the purported class may move the court to serve as lead plaintiff through counsel of their choice, or may choose to do nothing and remain an absent class member.  The complaint in this action was not filed by Kessler Topaz Meltzer & Check.
