Hagens Berman Investigates Advasa Holdings Following CFO Resignation

SAN FRANCISCO, Sept. 14, 2026 /CourierPR/ -- Hagens Berman Sobol Shapiro LLP, a national shareholders rights firm, has launched an investigation into Advasa Holdings, Inc. (NASDAQ: ADBT), following the sudden resignation of the company’s Chief Financial Officer (CFO) just two days after its direct listing on the Nasdaq Global Market.

Advasa Holdings completed its direct listing on August 25, 2026, under the ticker symbol "ADBT." However, on August 27, 2026, Katharyn Field, who also served as the principal accounting officer, abruptly resigned, citing personal reasons. This unexpected departure came with significant market impact, as the news sent Advasa’s share price plummeting by $1.96 on September 2, 2026, and another $1.38 the following day, resulting in a total loss of $3.34, or 90%, from the close on September 1, 2026.

The investigation by Hagens Berman focuses on the accuracy of Advasa’s financial disclosures and the stability of its internal accounting processes. The firm is encouraging investors who suffered substantial losses to submit their claims. As of September 14, 2026, Advasa has seen approximately $2.9 billion of its market capitalization erased since the direct listing.

Hagens Berman is also offering a reward to whistleblowers who provide non-public information that could assist in the investigation. Under the SEC Whistleblower program, individuals who provide original information that leads to a successful recovery may receive up to 30 percent of the recovery.

Hagens Berman Sobol Shapiro LLP is a global plaintiffs’ rights complex litigation firm that focuses on corporate accountability. The firm has a robust practice representing investors and whistleblowers in cases that have achieved significant results for those harmed by corporate negligence and other wrongdoings.
