•

Kahn Swick & Foti, LLC (“KSF”) and KSF partner, former Attorney General of Louisiana Charles C. Foti, Jr., reminded investors with substantial losses that they have until June 26, 2026 to file lead plaintiff applications in a securities class action lawsuit against SES AI Corporation (NYSE: SES). The action is pending in the United States District Court for the District of Massachusetts. The proposed class period covers investors who purchased or otherwise acquired SES securities between January 29, 2025 and March 4, 2026, inclusive.

Allegations in the Lawsuit

SES and certain of its executives are charged with failing to disclose material information during the class period, in violation of federal securities laws.

The alleged false and misleading statements and omissions include, among other things, claims that:

the company overstated its business outlook by exaggerating the potential results of agreements with companies that had limited or no operational capacity;
the company created the appearance of revenue by purchasing services tied to its own Molecular Universe transactions;
despite optimistic growth statements, SES AI faced significant logistics constraints in Q4 2025 that materially impacted revenue for that quarter;
these issues raised serious doubts about SES AI’s 2026 growth prospects, later reflected in weaker-than-expected 2026 revenue guidance; and
as a result, the company’s statements about its business, operations, and prospects were materially false and misleading and/or lacked a reasonable basis at relevant times.

Case Details

The case is Patel v. SES AI Corporation, et al., Case No. 26-cv-11894.
