8-K: ESS Tech Secures $31M Funding Package and Reports Improved Q2 Operations Amidst NYSE Delisting Threat

ESS Tech announced a $31 million insider-led funding package and reported significantly improved preliminary Q2 2025 operational financial results, while simultaneously facing a critical NYSE delisting threat due to its low market capitalization and cash position.

Summary

• ESS Tech entered into a Standby Equity Purchase Agreement (SEPA) with YA II PN, LTD, allowing the company to sell up to $25 million of common stock over a 3-year term, subject to certain limitations including a 19.99% Exchange Cap unless stockholder approval is obtained or the average sale price exceeds $1.48 per share.
• The company secured approximately $0.9 million in short-term promissory notes from directors, management, and Yorkville, repayable with a 15% exit fee by July 24, 2025, and issued warrants for up to 129,312 shares at an exercise price of $3.48 per share.
• A Sale and Leaseback Agreement was executed with UOP LLC, an affiliate of a greater than 5% stockholder, for the stack assembly line 1, generating $4.0 million in cash and applying $6,518,419.91 to pre-payments, with a 7-year lease term at $185,508.90 monthly.
• ESS Tech entered a Tax Credit Transfer Agreement for approximately $800,000, with $775,000 reimbursable if the option is not exercised by October 31, 2025.
• Preliminary unaudited financial results for Q2 2025 show revenue of approximately $2.4 million (294% increase from Q1 2025), cost of revenue of approximately $6.8 million (22% decrease), operating expenses of approximately $6.3 million (37% decrease), net loss of approximately $10.3 million (43% improvement), and Adjusted EBITDA loss of approximately $7.6 million (49% improvement).
• Cash, cash equivalents, and short-term investments as of June 30, 2025, are expected to be approximately $0.8 million, representing a 94% decrease compared to Q1 2025.
• The company achieved an approximately 80% reduction in monthly cash burn in June compared to the monthly average for the first five months of 2025.
• ESS Tech secured its first Energy Base order for an 8 MWh project, aligning with its strategic shift to 10+ hour products.
• The company received a NYSE notice on March 28, 2025, for not meeting the $50 million average global market capitalization and $50 million stockholders' equity standards, and on June 17, 2025, was notified that its 30-day average global market capitalization was less than $15 million, triggering potential prompt suspension and delisting procedures.

Sentiment

Score: 4

Explanation: While the company demonstrated significant operational improvements in Q2 2025 and secured a crucial funding package, its immediate liquidity position is dire with a 94% cash decrease, and it faces an imminent threat of NYSE delisting. The funding provides a temporary lifeline but highlights the precarious financial health and the need for further capital, creating substantial uncertainty for investors.

Positives

• Revenue increased by 294% to approximately $2.4 million in Q2 2025 compared to Q1 2025.
• Cost of revenue decreased by 22% to approximately $6.8 million in Q2 2025 compared to Q1 2025.
• Operating expenses decreased by 37% to approximately $6.3 million in Q2 2025 compared to Q1 2025.
• Net loss improved by 43% to approximately $10.3 million in Q2 2025 compared to Q1 2025.
• Adjusted EBITDA improved by 49% to a loss of approximately $7.6 million in Q2 2025 compared to Q1 2025.
• Monthly cash burn was reduced by approximately 80% in June compared to the monthly average for the first five months of 2025.
• Secured a $25 million Standby Equity Purchase Agreement, providing a flexible capital raising option.
• Completed a Sale and Leaseback Agreement generating $4.0 million in cash.

Negatives

• Cash, cash equivalents, and short-term investments decreased by 94% to approximately $0.8 million as of June 30, 2025, compared to Q1 2025.
• The company is at high risk of NYSE delisting, having received notice that its 30-day average global market capitalization fell below $15 million.
• The company explicitly states it will need to secure additional funding in the near term, with no assurance as to the timing, terms, or success of such transactions.
• The promissory notes are short-term, repayable by July 24, 2025, indicating immediate liquidity needs.

Risks

• Inability to close on the sale and leaseback transaction and sale of the production tax credits.
• Inability to raise additional capital under the Purchase Agreement or in other transactions.
• Failure to obtain stockholder approval to issue shares of common stock in excess of the Exchange Cap or for the shares issuable upon exercise of the Warrants.
• Inability to remain listed on the New York Stock Exchange, which could lead to limited market quotations, reduced liquidity, 'penny stock' designation, limited news/analyst coverage, decreased ability to issue additional securities or obtain financing, and impaired equity incentives.
• Actual financial results may differ materially from the preliminary unaudited financial information presented.
• Cash expenditures are expected to increase with a ramp in manufacturing activities, potentially exacerbating liquidity challenges if additional funding is not secured.

Future Outlook

The company intends to continue current cash management measures in the near term but expects that cash expenditures would increase with a ramp in manufacturing activities. It will need to secure additional funding in the near term, and there is no assurance as to the timing, terms, or success of such transactions. Forward-looking statements are subject to risks including the inability to close the sale and leaseback transaction and sale of production tax credits, inability to raise additional capital (including from the standby equity purchase agreement), failure to obtain stockholder approval, and inability to remain listed on the NYSE.

Management Comments

• "I am pleased to announce these transactions with our key partners coupled with a broader capital markets transaction that supports ongoing execution of our strategic pivot. This funding helps to strengthen our cash position to allow us to focus on the completion of key Energy Base contracting opportunities and to secure our broader capital raise."

Industry Context

The announcement highlights ESS Tech's continued efforts in the long-duration energy storage (LDES) sector, specifically with its iron flow battery technology. The strategic shift to a 10+ hour product, exemplified by the first 8 MWh Energy Base order, aligns with the growing industry demand for extended-duration storage solutions to support grid stability and renewable energy integration. The emphasis on U.S. manufacturing for the Energy Base product also positions the company within a trend of domestic supply chain development in the clean energy sector.

Comparison to Industry Standards

• The document does not provide specific comparable companies, projects, or results to benchmark ESS Tech's performance against industry standards. It notes that Adjusted EBITDA is a non-GAAP measure used by publicly-listed U.S. companies and securities analysts for comparison, but no direct comparisons are made within the filing.

Corporate Governance

Related Party Transactions

• Issuance of unsecured promissory notes to certain directors and members of management of the Company and the Investor (YA II PN, LTD).
• Tax Credit Transfer Agreement with SE Global Holdings, LLC, an affiliate of SB Energy Global Holdings One Ltd.

Stakeholder Impact

• Shareholders face potential dilution from the Standby Equity Purchase Agreement and warrants, and significant risk of reduced liquidity, 'penny stock' status, and impaired equity incentives if the company is delisted from the NYSE.
• Employees may be impacted by streamlined operations (though not explicitly stated as layoffs) and could see impaired equity incentives if the company is delisted.
• Creditors, particularly those holding the new promissory notes, have a short-term repayment horizon, and the company's overall financial health will impact its ability to meet all obligations.
• Customers, such as the recipient of the first 8 MWh Energy Base order, benefit from the company's continued product development and manufacturing capabilities, supported by the new funding.
• Suppliers may see increased demand as the company expects cash expenditures to increase with a ramp in manufacturing activities.

Next Steps

• Obtain stockholder approval for the issuance of common shares in excess of the Exchange Cap under the SEPA.
• Obtain stockholder approval for the issuance of shares underlying the warrants.
• Continue current cash management measures.
• Increase cash expenditures with a ramp in manufacturing activities.
• Maintain compliance with NYSE listing standards to avoid delisting.
