ESS Tech, Inc. Update: NYSE Listing Status

This report explains the latest news from ESS Tech, Inc. (ticker: GWH) in plain English. You don’t need a finance degree to understand what this means for your investment.

1. What happened?

ESS Tech, Inc. received a "deficiency notice" from the New York Stock Exchange (NYSE). To stay listed, a company’s stock must trade at an average of at least $1.00 per share over 30 consecutive trading days. As of June 8, 2026, the company’s 30-day average price dropped to $0.98, triggering this notice.

2. Why did it happen?

ESS Tech builds iron flow battery systems for large-scale energy storage. The company is currently spending heavily to grow its manufacturing capacity. When a stock price stays below $1.00, it shows that the market’s valuation has dropped below the NYSE’s minimum requirement. This often signals that investors are cautious about the company’s path to profitability or its ability to execute its long-term business plan.

3. Why does this matter?

Think of this as a regulatory "yellow flag." Your GWH shares will continue to trade on the NYSE as usual while the company works to fix the issue. However, there is a strict deadline. If the company fails to meet the requirements within six months, it could face delisting. Delisting would make the stock harder to trade and might limit its availability on some brokerage platforms.

4. Who is affected?

• Investors: You may see more price swings as the market reacts to this news. The company is considering its options, including a "reverse stock split." This combines existing shares into fewer, higher-priced shares to mathematically boost the price per share. While this doesn't change the total value of your investment, it is a common move to satisfy exchange rules.
• Customers and Operations: This is strictly a stock exchange issue. It does not affect the company’s ability to build batteries, finish customer contracts, or meet its reporting requirements with the SEC.

5. What happens next?

The company has a six-month "cure period" to get back in line with NYSE rules. To fix the deficiency, the stock must close at $1.00 or higher on the last trading day of any month during this period, and maintain an average price of at least $1.00 over the 30 trading days leading up to that date.

6. What should you consider as an investor?

• Understand the notice: This is a standard warning for companies with a low stock price. It is not an immediate removal from the exchange.
• Watch for filings: Keep an eye out for future 8-K filings or press releases. These will explain exactly how the board of directors plans to regain compliance.
• Focus on the business: A stock price reflects how the market feels about the company’s performance. Keep tracking the company’s progress in scaling battery production and winning new contracts. These operational milestones are what drive long-term value. If you are a long-term investor, ask yourself if the company's technology and market position still align with your original reasons for buying the stock.
