ESS Tech Inc

The New York Stock Exchange announced that its regulatory staff has determined to commence proceedings to delist the common stock of ESS Tech, Inc., ticker symbol GWH, from the NYSE. NYSE Regulation reached the decision under Section 802.01B of the NYSE's Listed Company Manual because the company fell below the continued listing standard requiring an average global market capitalization of at least $15,000,000 over a consecutive 30 trading day period. Trading in the company's common stock will be suspended immediately. The Exchange had previously announced on September 24, 2026 that the company was no longer suitable for listing under Section 802.02 of the Listed Company Manual, as it was unable to demonstrate regained compliance with the applicable standard by the expiration of the maximum plan period. ESS Tech has a right to a review of these determinations by a Committee of the NYSE Board of Directors, and the NYSE will apply to the Securities and Exchange Commission to delist the stock upon completion of all applicable procedures, including any appeal by the company.
