LOS ANGELES–(BUSINESS WIRE)–$ADTN #ADTNThe Schall Law Firm, a national shareholder rights litigation firm, announces that it is investigating claims on behalf of investors of ADTRAN, Inc. (“ADTRAN” or “the Company”) (NASDAQ: ADTN) for violations of the securities laws.

The investigation focuses on whether the Company issued false and/or misleading statements and/or failed to disclose information pertinent to investors. ADTRAN announced “preliminary” earnings for the second quarter of 2019 on July 17, 2019. This was due to the Company’s ongoing assessment of excess and obsolete inventory reserves (“E&O reserves”). On August 12, 2019, ADTRAN indicated that it would be incapable of filing its quarterly financial report with the SEC in a timely manner due to a material weakness related to E&O reserves.
