ESS Statement on NASDAQ Clerical Error

February 22, 2024

ESS Tech, Inc. (“ESS”) (NYSE: GWH), has become aware of a clerical error posted on the NASDAQ website related to the shareholdings in the company by Softbank Group Corp. (Softbank).

The website erroneously showed that Softbank’s holdings in ESS had decreased significantly in the fourth quarter of 2023.  Softbank’s holdings of 35,953,699 shares were unchanged from the third quarter and have in fact remained unchanged since ESS’s listing as a publicly traded company in October 2021.  Softbank remains ESS’s largest shareholder.

NASDAQ has advised that the website will be corrected.
