The Schall Law Firm, a national shareholder rights litigation firm, announces that it is investigating claims on behalf of investors of ESS Tech, Inc. (“ESS Tech” or “the Company”) (NYSE: GWH) for violations of the securities laws.

The investigation focuses on whether the Company issued false and/or misleading statements and/or failed to disclose information pertinent to investors. ESS Tech is the subject of a report published by Grizzly Research on December 7, 2022. According to the report, the Company’s partnership with Energy Storage Industries Asia Pacific (“ESI”) was not what it appeared to be. The report claims that ESI is a related party with no real staff, office, or ongoing business. The report adds that the Company concealed the fact that ESI was a de-facto subsidiary, not a true third party. Based on this news, shares of ESS Tech fell by more than 7.7% on the same day.
