Class Action Lawsuit Filed Against Alto Neuroscience, Inc.

Pomerantz LLP, a leading law firm known for its success in corporate class action cases, has officially announced the filing of a class action lawsuit against Alto Neuroscience, Inc., a clinical-stage biopharmaceutical company, along with certain officers of the firm. The case has been submitted to the United States District Court for the Northern District of California, bearing the docket number 25-cv-06105. This lawsuit is particularly significant for those who purchased or acquired Alto's common stock either during its initial public offering on February 2, 2024, or within the subsequent class period ending on October 22, 2024.

The class action seeks to represent a group of individuals and entities who, apart from the defendants, engaged in transactions influenced by the Offering Documents tied to Alto’s IPO. The claims against the defendants are based on alleged violations of the Securities Act of 1933 and the Securities Exchange Act of 1934. Investors who were affected are advised to step forward, as the deadline to request lead plaintiff status is September 19, 2025.

Alto Neuroscience operates primarily in the United States and is focused on discovering and developing innovative therapeutics targeting central nervous system disorders. Among its products, the anticipated ALTO-100 was highlighted for its prospective ability to assist patients with major depressive disorder (MDD) and showcase a distinct mechanism of action from other CNS therapies. The company had expressed confidence that ALTO-100 could potentially be classified as a first-in-class medication, pending successful regulatory approval.

On January 12, 2024, Alto filed a registration statement on Form S-1, which was subsequently approved, allowing the company to proceed with its IPO. The public trading of Alto’s common stock commenced with a price of $16.00 per share, generating proceeds of approximately $119.6 million post-underwriting fees. However, allegations filed in the complaint assert that the Offering Documents were negligently composed and contained material misstatements or omissions regarding key aspects of the company's operations.

Investors were led to believe that ALTO-100 was performing more effectively in clinical tests for MDD than other reports indicated. Specifically, the lawsuit claims that the data surrounding ALTO-100's efficacy was overstated, leading to inflated expectations regarding Alto's business and financial outlook.

The turning point for the company's stock unfolded on October 22, 2024, when Alto released concerning results from ALTO-100's Phase 2b trial that showed it had failed to meet its primary endpoint. The announcement triggered a substantial decline in Alto's stock price, plummeting over 69% to close at $4.36 per share the following day. Market analysts promptly revised their assessments of Alto, with Jeffries, for instance, slashing its price target and questioning the company's overall approach to biomarker development in CNS treatments.

The complaint cites that, as of the filing date, Alto’s stock continues to trade well below its initial offering price of $16.00, placing significant financial pressure on investors. Pomerantz LLP is renowned for its expertise in corporate litigation and has been pivotal in recovering substantial damages on behalf of investors adversely impacted by securities fraud.
