The investigation is centered around whether ESS Tech, a company, made false or misleading statements or failed to disclose important information to its investors. This was brought to light by a report published by Grizzly Research on December 7, 2022, which alleged that the Company’s partnership with Energy Storage Industries Asia Pacific (ESI) was not genuine. According to the report, ESI was a related party with no actual employees, office or ongoing operations and that ESS Tech had concealed the fact that ESI was a subsidiary instead of an independent third party. As a result of this news, ESS Tech’s shares dropped by more than 7.7% on the same day.
