INVESTOR ALERT: Kirby McInerney LLP Continues Investigation of Shareholder Claims Against ADTRAN, Inc.

The law firm of Kirby McInerney LLP is investigating potential claims against ADTRAN, Inc. ("ADTRAN" or the "Company") ADTN. This investigation concerns whether ADTRAN has violated federal securities laws and/or engaged in other unlawful business practices.

On July 17, 2019, ADTRAN announced "preliminary" earnings for the second quarter of 2019 due to the Company's assessment of its current and previously reported E&O reserves. On this news, the Company's share price fell $3.69 per share, or 23.3%, to close at $12.13 on July 18, 2019.

On August 12, 2019, ADTRAN disclosed its inability to timely file its quarterly financial report with the SEC, admitting to material weaknesses in its internal controls, resulting in a misstatement of the Company's previously reported E&O reserves.
