ESS Tech, Inc. 8-K

What Happened
The New York Stock Exchange notified ESS Tech, Inc. on June 30, 2026, and publicly announced on July 1, 2026, that it has commenced proceedings to delist the Company’s Public Warrants and has immediately suspended trading in those warrants. The Public Warrants were issued in connection with ACON S2 Acquisition Corp.’s IPO and trade under the symbol GWH.W. Per the warrant terms, each 15 Public Warrants is exercisable for one share of ESS Tech common stock at $172.50 per share (equivalent to $11.50 per warrant). Trading of ESS Tech’s common stock (ticker GWH) is not affected and will continue on the NYSE, subject to the company meeting other listing requirements.

Key Details

• NYSE notification to the Company: June 30, 2026; NYSE public announcement: July 1, 2026.
• Action: Commencement of delisting proceedings for the Public Warrants and immediate suspension of trading.
• Reason cited: “Abnormally low” trading price levels under Section 802.01D of the NYSE Listed Company Manual.
• Impact on securities: Only the Public Warrants (GWH.W) are suspended/delisting-proceeded; common stock (GWH) continues to trade.

Why It Matters
Warrant holders are directly affected: trading in the Public Warrants has been suspended and the NYSE has started delisting proceedings, which could lead to removal of those warrants from the exchange. Common-stock holders are not impacted by this action for now—the company’s shares remain listed and tradable on the NYSE. Investors holding or considering the warrants should monitor future company and NYSE announcements for next steps; common-stock investors should watch for any additional notices about the company’s compliance with NYSE listing standards.
