Business Context and Reporting Period
Company: Energy Vault Holdings, Inc.
Filing Type: Form 8-K (Current Report)
Date of Report: September 22, 2025
Reporting Period: Event-based filing regarding a material definitive agreement entered into on September 22, 2025.
Key Financial Metrics and Transaction Details
This filing details a financing transaction rather than periodic financial performance metrics (revenue, profit, cash flow). Key terms of the new debt instrument include:
- Instrument: Senior unsecured convertible debentures.
- Total Capacity: Up to $50.0 million in aggregate principal amount.
- Initial Funding: $30.0 million funded at closing.
- Additional Tranche: Up to $20.0 million available within ten business days following a preferred equity investment and effectiveness of a resale registration statement.
- Interest Rate: 7% annual (increases to 18% during an uncured event of default).
- Issuance Price: 97% of principal.
- Maturity: 18 months.
- Conversion Price: $4.50 per share for the initial tranche (150% of VWAP prior to closing).
- Use of Proceeds: General corporate working capital, storage project development, construction, and growth initiatives.
Material Changes and Unusual Items
The primary material change is the entry into a Securities Purchase Agreement with YA II PN, Ltd. Key structural features include:
- Amortization Schedule: Monthly installments of principal and accrued interest begin on the 65th day after closing. Installments range from $0.4 million to $1.0 million per $10 million of principal, depending on the payment date.
- Payment Waiver: No installment is due if the daily VWAP exceeds the Fixed Price by at least 15% for five prior trading days.
- Amortization Events: If specific negative triggers occur (e.g., stock price below floor price for 5 of 7 days), monthly installments increase to the greater of the scheduled amount or 20% of outstanding principal, and the cash payment premium increases to 10%.
- Ownership Caps: Investor conversion is capped at 19.99% of outstanding common stock (Exchange Cap) and beneficial ownership is limited to 4.99% (increasable to 9.99% with consent).
- Warrant Issuance: On August 18, 2025, the company sold 4,500,000 warrants to Dorado Goose LLC with exercise prices ranging from $1.50 to $3.00, exercisable until August 18, 2027.
Guidance, Outlook, and Risks
Management Commentary: The company intends to use proceeds to support energy storage project development and general working capital. The filing notes that the company may redeem debentures for cash if the VWAP is below the Fixed Price, or at 110% of principal in a change of control scenario.
Risks and Contingencies:
- Liquidity Constraints: The agreement includes limitations on additional indebtedness and liens, with exceptions for specific project-level indebtedness.
- Equity Line Restrictions: Use of the At-The-Market (ATM) program is restricted; if used, 25% of gross proceeds must reduce debenture principal, and a three-day cooling-off period applies after investor conversions.
- Registration Rights: The company must file a registration statement for resale of convertible shares within 10 business days and seek effectiveness within 60 days.
- Default Risks: Interest rates double to 18% and amortization accelerates significantly upon an "Amortization Event."
Investor Verification Checklist
- Verify the effectiveness of the resale registration statement required for the additional $20.0 million tranche.
- Confirm the current stock price relative to the $4.50 conversion price and the 20% floor price to assess conversion likelihood and amortization triggers.
- Review the status of the preferred equity investment required to unlock the second tranche of funding.
- Assess the impact of the 7% interest rate and mandatory monthly principal payments on the company's near-term cash flow.
- Check for any subsequent filings regarding the 4,500,000 warrants issued in August 2025 and their potential dilution impact.
