Potential Concerns Under Investigation

Lawyers are investigating whether Western Alliance Bancorporation may have made misleading statements or omitted critical information regarding its loan portfolio and credit quality between October 2024 and October 2025.

On October 16, 2025, Western Alliance Bancorporation disclosed through a Form 8-K filing that, in August, the bank initiated a lawsuit alleging the borrower failed to provide collateral loans in first position, among other claims, on a Cantor Group V, LLC loan facility. This disclosure revealed that collateral for the credit facility had been fraudulently misrepresented, which appears to have caused investors to reassess the company’s previously reported credit risk.

Following this announcement, Western Alliance Bancorporation’s share price dropped 10.8%, an $8.52 per share decline from a close of $78.84 on October 15 to $70.32 at market close on October 16, 2025, resulting in significant harm to investors.

Attorneys may examine whether Western Alliance Bancorporation’s prior public statements about asset quality and credit risk were misleading by omission. For example, in the Q3 2024 press release, the company stated “asset quality remained stable” with nonperforming assets at only 0.45%. Similar reassurances allegedly appeared in subsequent quarterly releases, such as “Asset quality remained stable with nonperforming assets declining to 0.60%” and “Asset quality continued to perform as expected”.

Lawyers may investigate whether these statements failed to disclose the existence of the Cantor loan fraud, which later proved to be material.

Additionally, Western Alliance Bancorporation reported low net charge-offs and highlighted decreasing “criticized loans,” signaling improving credit conditions. For instance, the company reported net charge-offs of 0.18% in Q4 2024 and 0.20% in Q1 2025 . However, the investigation might look into whether these figures were accurate representations of the company’s true credit risk, given the later revelation of a significant loan fraud.

Other potential red flags that lawyers might examine include a rapid increase in the company’s provision for credit losses, which increased from $31.2 million in Q1 2025 to $39.9 million in Q2 2025, and a spike in repossessed assets from $8 million in mid-2024 to $218 million by Q2 2025. Attorneys are investigating whether these developments were accurately highlighted by management in public disclosures.
