HUNTSVILLE, Ala.–(BUSINESS WIRE)–ADTRAN, Inc. (NASDAQ:ADTN) (“ADTRAN” or the “Company”) announced today that it received a standard notification letter from The Nasdaq Stock Market LLC (“Nasdaq”), dated August 15, 2019, stating that, as a result of not having timely filed its Quarterly Report on Form 10-Q for the period ended June 30, 2019 (the “Form 10-Q”), ADTRAN is not in compliance with Nasdaq Listing Rule 5250(c)(1), which requires timely filing of periodic financial reports with the Securities and Exchange Commission (the “SEC”). This notice has no immediate effect on the listing of ADTRAN’s common stock on the Nasdaq Global Select Market.

Nasdaq’s listing rules provide the Company with 60 calendar days from the date of the notice to submit a plan to regain compliance. The Company expects to file the Form 10-Q within this 60 calendar day period, eliminating the need for the Company to submit a formal plan to regain compliance.

As has been previously publicly disclosed by the Company, the delay in preparing and filing the Form 10-Q is due to the Company’s ongoing assessment of the accuracy and reasonableness of its current and previously reported excess and obsolete inventory reserves (“E&O Reserves”). ADTRAN is working diligently to finalize its assessment of its current and previously reported E&O Reserves and to finalize and file the Form 10-Q.
