Pomerantz Law Firm Launches Investigation into ADTRAN Holdings, Inc. for Investor Claims

Pomerantz Law Firm Investigates ADTRAN Holdings, Inc.

In a significant development for shareholders, Pomerantz LLP has initiated an investigation regarding potential claims on behalf of investors in ADTRAN Holdings, Inc. (NASDAQ: ADTN). The firm is probing whether the company and its senior officers have engaged in fraudulent activities or any unlawful business practices that could have adversely affected its investors.

Background of the Investigation

This investigation stems from troubling disclosures made by ADTRAN in a recent filing with the U.S. Securities and Exchange Commission (SEC). On May 13, 2025, the company publicly announced that its audited consolidated financial statements for the years ended December 31, 2024, and December 31, 2023, as well as its unaudited condensed financial statements for interim periods in 2024, should no longer be considered reliable. ADTRAN identified that these documents, known collectively as the 'Non-Reliance Periods', would require restatement due to inaccuracies.

Management indicated that they are evaluating the implications of these revelations on their internal controls over financial reporting as of December 31, 2024, and have acknowledged finding at least one additional material weakness in their financial practices. This announcement triggered a negative reaction in the stock market, resulting in a noticeable decline in ADTRAN’s share price, which fell by 4.79% to end at $8.15 on May 14, 2025, immediately following the news.

What This Means for Investors

For investors of ADTRAN who may have suffered losses as a result of these developments, the situation calls for immediate attention. Pomerantz LLP is reaching out to affected shareholders to discuss their options and the potential for joining a class-action lawsuit aimed at holding the company accountable for any misconduct related to these financial irregularities.
