Investor Alert: Investigation into Atara Biotherapeutics, Inc.

In an alarming development for investors, Pomerantz LLP has initiated an investigation concerning possible wrongdoing at Atara Biotherapeutics, Inc. (NASDAQ: ATRA). The firm is reaching out to shareholders who may have suffered losses as a result of alleged securities fraud or improper business practices by the company.

Background of the Investigation

On January 12, 2026, Atara Biotherapeutics received a Complete Response Letter (CRL) from the U.S. Food and Drug Administration (FDA), regarding its Biologics License Application (BLA) for EBVALLO™ (tabelecleucel), intended for patients with Epstein-Barr virus positive post-transplant lymphoproliferative disease (EBV+ PTLD). The CRL stated that the FDA could not approve the BLA in its current form, citing that the data from the originally adequate ALLELE trial was now seen as insufficient. The implications from this announcement led to a stark drop in Atara's stock price, down nearly 57%, closing at $5.88 per share on that same day.

This startling shift raises questions about Atara's previous disclosures and the integrity of the data presented to investors. Given that significant stock value was lost almost instantly, shareholders are encouraged to assess their investments with care and consider reaching out to Pomerantz for legal counsel.

What Investors Should Know

Investors of Atara Biotherapeutics, or those who bought shares prior to January 12, 2026, may feel the repercussions of this FDA decision and the company’s lack of further correlation between their clinical data and the BLA approval. Pomerantz LLP is advocating for shareholders to come forward, particularly those who believe their investments are associated with fraudulent activities or misrepresentation.

Danielle Peyton, a senior attorney at Pomerantz, is handling the inquiries regarding this case. Interested parties can contact her directly through [email protected] or by phone at 646-581-9980, ext. 7980.
