Bronstein, Gewirtz & Grossman LLC Urges SES AI Corporation Investors to Act: Class Action Filed Alleging Investor Harm

•

Bronstein, Gewirtz & Grossman, LLC announced that a class action lawsuit has been filed against SES AI Corporation (NYSE: SES) and certain of its officers.

The lawsuit seeks to recover damages for alleged violations of federal securities laws on behalf of investors who purchased or otherwise acquired SES AI securities between January 29, 2025 and March 4, 2026, inclusive (the “Class Period”). Investors are encouraged to review the complaint at bgandg.com/SES.

Allegations in the complaint

The complaint alleges that, throughout the Class Period, the defendants made false and/or misleading statements and/or failed to disclose that:

SES AI overstated its business prospects by materially overstating expected results that could be achieved through deals with companies that have limited or no operations.
SES AI created an appearance of revenue by purchasing services in exchange for purchases of Molecular Universe.
Despite positive statements about growth prospects, SES AI was affected by material logistics constraints in the fourth quarter of 2025 that would materially affect Q4 2025 revenues.
The foregoing called into question SES AI’s growth prospects for 2026, which were allegedly confirmed by lower-than-expected 2026 revenue guidance.
As a result, defendants’ statements about SES AI’s business, operations, and prospects were materially false and misleading and/or lacked a reasonable basis at all relevant times.

A class action lawsuit has already been filed. A copy of the complaint is available at bgandg.com/SES, or investors may contact Peretz Bronstein, Esq. or Client Relations Manager Nathan Miller at 917-590-0911.
