Alto Neuroscience, Inc. (ANRO) Shareholder Investigation

April 13, 2026

Shamis & Gentile, P.A. is investigating potential shareholder claims on behalf of Alto Neuroscience, Inc. ("Alto Neuroscience" or the "Company") (ANRO) against certain of its directors and officers for alleged breaches of fiduciary duties and other violations of law. Concerned shareholders are advised to contact the firm now.

According to a recently filed federal securities class action complaint, Alto Neuroscience and certain of its officers allegedly made materially false and misleading statements regarding the Company's business, operations, and prospects. It is alleged that defendants misrepresented or failed to disclose that ALTO-100, the Company’s lead product candidate for major depressive disorder (MDD), was less effective than had been represented to investors.

As a result, the clinical, regulatory, and commercial prospects for ALTO-100, as well as Alto Neuroscience’s overall business and financial outlook, may have been overstated in public disclosures.

The Company’s board and executive officers may have failed to institute and follow appropriate board-level systems to monitor clinical trial integrity and disclosure controls, particularly with respect to ALTO-100 prior to and following the Company’s February 2, 2024 initial public offering. The investigation will focus on whether red flags regarding clinical trial results or compliance issues were overlooked or not adequately escalated to the board, and whether officers or directors potentially ignored or failed to report adverse information, resulting in harm to the Company.

If you purchased Alto Neuroscience, Inc. (NYSE: ANRO) prior to October 22, 2024, and still hold some shares today, you can seek corporate reforms over the alleged misconduct, the return of funds back to the Company, and a court approved incentive award at absolutely no cost to you.
