DASAN Zhone Announces Receipt of Letter from Nasdaq Regarding Non-Compliance

Oakland, California, November 18, 2016 - DASAN Zhone Solutions, Inc. (NASDAQ: DZSI), a global leader in fiber access transformation for enterprise and service provider networks, today announced that on November 16, 2016, it received a letter from The Nasdaq Stock Market LLC ("Nasdaq") notifying the company that it was not in compliance with the periodic filing requirements for continued listing set forth in Rule 5250(c)(1) of the Nasdaq Marketplace Rules because its Quarterly Report on Form 10-Q for the quarter ended September 30, 2016 (the "Form 10-Q") filed with the Securities and Exchange Commission (the "SEC") on November 15, 2016 had not yet been reviewed by an independent registered public accounting firm. Nasdaq provided the company until January 15, 2017 to submit a plan to regain compliance and, if Nasdaq accepts the company's plan, Nasdaq can grant the company an additional compliance period until May 8, 2017 to regain compliance.  As previously disclosed, the company is still in the process of engaging a new independent registered public accounting firm following the previously disclosed resignation of KPMG, LLP, and the company intends to file an amendment to the Form 10-Q promptly following the company's engagement of an independent registered public accounting firm and the completion of their review of the interim unaudited financial statements as of and for the three and nine months ended September 30, 2016.  If the company is unable to regain compliance with the periodic filing requirements set forth in Rule 5250(c)(1) of the Nasdaq Marketplace Rules during the compliance period, the company's common stock would be subject to delisting.  Delisting from the Nasdaq Capital Market could have a material adverse effect on the company's business and on the trading of its common stock.
