Pomerantz Law Firm Initiates Class Action Against Alto Neuroscience

On September 13, 2025, Pomerantz LLP, a leading law firm specializing in class action litigation, announced the filing of a significant lawsuit against Alto Neuroscience, Inc. (NYSE: ANRO) and certain key individuals associated with the company. This class action, which is now officially lodged in the United States District Court for the Northern District of California, asserts serious allegations regarding the accuracy of information presented to prospective investors during Alto's initial public offering (IPO) conducted on February 2, 2024.

The lawsuit is pertinent to all individuals and entities that purchased Alto common stock or securities from the period encompassing the IPO up until October 22, 2024. Allegations include that the Offering Documents presented to potential investors were poorly constructed, containing misleading information or failing to disclose vital details concerning the company's prospects and operations.

Background on Alto Neuroscience's Operations

Alto Neuroscience operates as a clinical-stage biopharmaceutical company that focuses on innovative treatments for various neurological conditions. At the time of their IPO, the company was promoting ALTO-100, a drug targeting major depressive disorder (MDD), claiming it had a unique mechanism that could potentially place it ahead of competitors. According to the company, ALTO-100 was engaged in a Phase 2b clinical trial, aiming to explore its efficacy in treating MDD.

However, the lawsuit claims that as the clinical trials progressed, the effectiveness of ALTO-100 was misrepresented. The complaint alleges that statements made by the company and its executives skewed expectations about the drug’s viability, overstating both its clinical and commercial prospects.

Misleading Claims and Stock Performance

On October 22, 2024, following the completion of the Phase 2b trial, Alto Neuroscience publicly announced that ALTO-100 did not meet its primary efficacy endpoints when compared to a placebo, which was a shocking revelation for investors. Market analysts reacted swiftly, with one firm, Jeffries, immediately cutting the price target from $33 to $17 and questioning the company's research approach within the realm of central nervous system disorders.

Consequently, shares plunged by nearly 70%, closing at only $4.36 the following day—a stark contrast from its IPO price of $16.00. As of this lawsuit’s initiation, Alto’s stock value remains significantly lower than the initial public offering price, inflicting considerable financial damage on investors who relied on the information provided by the company.

Legal Proceedings and Investor Rights

As part of the ongoing case, investors who purchased shares during the applicable timeframe have been called upon to step forward to seek appointment as Lead Plaintiff. The law firm has provided resources for individuals interested in joining the class action. The deadline for such motions is September 19, 2025.
