The Law Offices of Frank R. Cruz announces that a class action lawsuit has been filed on behalf of persons and entities that purchased or otherwise acquired ESS Tech, Inc. (“ESS” or the “Company”) (NYSE: GWH) securities between August 11, 2022 and December 7, 2022, inclusive (the “Class Period”). ESS investors have until March 13, 2023 to file a lead plaintiff motion.

On December 7, 2022, Grizzly Research published a report which alleged, among other things, that ESS’s largest partner, Energy Storage Industries Asia Pacific (“ESI”), is a related party with no real staff, office, or any relevant ongoing business activity. Furthermore, the report claimed that the Company concealed the fact that ESI was a de-facto subsidiary, not a true third party.

On this news, ESS’s stock price fell $0.22, or 7.7%, to close at $2.64 per share on December 7, 2022, thereby injuring investors.

The complaint filed in this class action alleges that throughout the Class Period, Defendants made materially false and/or misleading statements, as well as failed to disclose material adverse facts about the Company’s business, operations, and prospects. Specifically, Defendants failed to disclose to investors that: (1) the purported agreement with ESI was in fact an undisclosed related party transaction because ESI was a de-facto subsidiary of ESS masquerading as third-party client; (2) ESS misled investors with their partnership announcement to signal business success to investors; and (3) as a result, Defendants’ positive statements about the Company’s business, operations, and prospects were materially misleading and/or lacked a reasonable basis at all relevant times.
