ESS Tech, Inc. said NYSE Regulation suspended trading in its common stock on October 2, 2026 and began delisting proceedings after the company fell below the NYSE standard requiring average global market capitalization of at least $15,000,000 over a consecutive 30-trading-day period. This is separate from a September 24, 2026 delisting determination under another NYSE standard, which remains in effect.
As of October 5, 2026, the stock may be quoted and traded in the over-the-counter market under GWHT. ESS says that market is significantly more limited and likely to be less liquid, and could further depress the trading price. The company intends to request review by an NYSE committee within 10 business days of receiving the notice and continues pursuing strategic transaction opportunities it says could address the market-capitalization issue. ESS also said it remains subject to Exchange Act reporting requirements.
ESS Tech, Inc. said NYSE Regulation determined to commence proceedings to delist its common stock, which trades as GWH, after the company was unable to demonstrate that it had regained compliance with continued-listing standards by the end of its maximum plan period. The standard requires either at least $50 million in stockholders’ equity or at least $50 million in total market capitalization on a 30-trading-day average basis.
ESS Tech currently intends to request a review by an NYSE committee and appeal the determination, although it said there can be no assurance the appeal will succeed. A written review request must be filed within 10 business days after receipt of the notice. NYSE will announce a trading-suspension date if no timely review is requested, the company decides not to appeal, the committee determines trading should be suspended, or other material developments occur. After a suspension announcement, NYSE would apply to the SEC to delist the shares.
ESS Tech, Inc. seeks approval for a board-discretionary reverse split at a whole-number ratio from 1-for-8 to 1-for-30, with a proportional reduction in the 1,000,000,000 authorized common shares. If approved, the board may choose the ratio or abandon both actions before the meeting’s one-year anniversary; approval would not require implementation. ESS says the proposal is intended to address an NYSE minimum-price deficiency after its average closing price was below $1.00 over 30 consecutive trading days; the stock closed at $0.3510 on the September 14, 2026 record date.
Stockholders are also asked to approve issuance upon exercise of warrants from the August 2026 offering: 6,400,000 shares sold at $0.50 per share, plus warrants for 13,120,000 shares in total, including the placement-agent warrant. The offering closed August 21, 2026 and yielded approximately $2.5 million in net proceeds. The warrants cannot be exercised before stockholder approval; specified price-protection and reverse-split adjustments could increase the number of warrant shares. The board recommends a FOR vote on both proposals.
ESS Tech, Inc. (GWH) has filed a resale shelf registration on Form S-3 covering up to 13,120,000 shares of common stock issuable upon exercise of outstanding warrants held by existing investors and the placement agent. This consists of 12,800,000 shares underlying investor Common Warrants and 320,000 shares underlying a Placement Agent Warrant, each with an exercise price of $0.50 per share.
The company will not receive proceeds from resale of the shares, but could receive up to approximately $6.6 million in cash if all warrants are exercised for cash. About $500,000 of any such proceeds is expected to be used to repay a promissory note, with the balance for working capital and general corporate purposes. The warrants are not exercisable unless and until stockholders approve both the issuance and a reverse stock split aimed at regaining NYSE minimum price compliance.
The filing highlights potential dilution and share overhang from the registered shares, as well as price-protection and reverse-split adjustment mechanics that can increase the number of shares issuable under the warrants. ESS’s latest audited financial statements include an auditor’s paragraph indicating substantial doubt about the company’s ability to continue as a going concern.

ESS Tech, Inc. (GWH) entered into definitive agreements for a capital raise combining a registered direct offering and a concurrent private placement. The company sold 6,400,000 shares of common stock at $0.50 per share and issued 12,800,000 common stock purchase warrants with a $0.50 exercise price, generating expected gross proceeds of $3.2 million and net proceeds of about $2.5 million.
The warrants are unregistered, will become exercisable only after stockholders approve both the warrant issuance under NYSE rules and a reverse stock split, and will remain exercisable for five years after that approval. ESS plans to use the proceeds for general corporate purposes, working capital and to repay about $1.5 million under a promissory note with YA II PN, Ltd. The deal was led by Roth Capital Partners, which received a 7% cash fee and a warrant for 320,000 shares. ESS agreed to a 90-day issuance restriction and 90‑day lock-ups for directors and executive officers, and adopted warrant beneficial ownership limits of 4.99% or 9.99% to cap any holder’s post‑exercise ownership.
ESS Tech, Inc. (GWH) is conducting a primary offering of 6,400,000 shares of common stock at $0.50 per share, for gross proceeds of $3.2 million. After a 7.0% placement fee and expenses, ESS expects net proceeds of about $2.5 million.
In a concurrent private placement, ESS will issue unregistered warrants for up to 12,800,000 shares to investors and 320,000 warrants to the placement agent, all with a $0.50 exercise price and five‑year terms starting after required stockholder approval. ESS plans to use proceeds for general corporate purposes, working capital, and to repay about $1.5 million on an outstanding promissory note.
Risk disclosures highlight substantial going concern doubt, significant dilution (about $0.55 per share to new investors), heavy reliance on additional capital, and multiple NYSE listing deficiencies that could result in delisting and reduced liquidity if not cured.
ESS Tech, Inc. received an amended Schedule 13G filing (Amendment No. 2) reporting that Alyeska Investment Group, L.P., Alyeska Fund GP, LLC, and Anand Parekh collectively beneficially own 1,400,000 shares of ESS Tech common stock.

The filing also indicates that the group now holds 5 percent or less of the class.
