Block & Leviton LLP (www.blockesq.com), a Boston based securities litigation firm representing investors nationwide, announces that a class action lawsuit has been filed in Boston against Sonus Networks, Inc. (“Sonus” or the “Company”), which now trades under the name Ribbon Communications, Inc. (NASDAQ: RBBN), and certain of its executives alleging violations of the federal securities laws. Class members interested in serving as lead plaintiff must move the Court prior to the January 7, 2019 lead plaintiff deadline.

On August 7, 2018, the Securities and Exchange Commission (“SEC”) issued a press release and order charging Sonus and certain of its executives with making material misstatements on January 8, 2015 and February 18, 2015 concerning Sonus’s quarterly revenue estimates and guidance for the first quarter of 2015. The Company agreed to pay civil penalties of almost $2 million to settle the charges brought by the SEC. When the January 8, 2015 and February 18, 2015 falsehoods were disclosed to the market on March 24, 2015, Sonus shares fell over 33%.

If you purchased or otherwise acquired Sonus securities between January 8, 2015 and March 24, 2015 and have questions about your legal rights, or possess information relevant to this investigation, you are encouraged to contact Jake Walker at (888) 868-2385, by email at jake@blockesq.com, or by visiting http://shareholder.law/sonus.
