ESS Tech, Inc. announced on October 2, 2026, that the New York Stock Exchange (NYSE) has suspended trading of its common stock and initiated delisting proceedings. The NYSE staff determined to commence these actions pursuant to Section 802.01B of the NYSE Listed Company Manual, which requires listed companies to maintain an average global market capitalization of at least $15 million over a consecutive 30-trading-day period.
Following the suspension, the Company’s common stock, ticker symbol GWHT, may now be quoted and traded in the over-the-counter market as of October 5, 2026. The Company noted that the over-the-counter market is significantly more limited than the NYSE and that trading there is likely to result in less liquidity and could further depress the trading price of the stock.
ESS Tech stated that it intends to request a review of the NYSE Regulation determination by a Committee of the NYSE Board of Directors. This review must be requested in writing within ten business days of receiving the notice. The Company emphasized that shareholders are not required to take any steps related to the suspension and that shares remain outstanding and held in the same accounts.
The Company also confirmed that it remains subject to the reporting requirements of the Securities Exchange Act of 1934 and intends to continue filing annual, quarterly, and current reports with the SEC. Management indicated its focus remains on pursuing strategic transaction opportunities on an expedited basis to address market capitalization issues.
