Future Outlook

The company estimates full-year 2025 revenue to be between $200 million and $250 million, which is within the prior guidance range, reflecting the timing of U.S. battery deliveries and project timelines. It is targeting a total cash balance of $60-75 million at the end of Q3 2025, including the $18 million Cross Trails project financing completed in July and an anticipated $27 million in net ITC proceeds in September. Upon the closing of the $300 million Preferred Equity Investment, expected within the next 30-60 days, Energy Vault intends to host a Virtual Investor Day to provide a comprehensive overview of the Asset Vault platform, its project pipeline, financial projections, and long-term strategic vision.

Management Comments

• "We made good progress in our key growth geographies in the quarter executing on our core strategies, including construction progress on our first two energy storage projects in Australia, announcing a new regional expansion within the U.S. with the public utility contract with Consumers Energy, and perhaps most significantly, entering into agreement for a $300 million preferred equity funding that will secure the capital to execute upon our attractive project development portfolio of 3GWs of storage IPP projects under our build-own-operate strategy."
• "In addition to creating large, annual recurring cash streams from the owned asset portfolio, the new Asset Vault storage IPP will enhance cash accretion back to Energy Vault which will construct the projects, all incremental to our other energy storage solutions business."
• "Importantly, we also executed well on putting more cash on the balance sheet, completing our second project financing for the Cross Trails BESS in Texas which completed in July, following a 23% increase in cash at the end of Q2 at the high end of our previous guidance range."

Industry Context

This announcement highlights Energy Vault's strong positioning within the rapidly expanding grid-scale energy storage market. The significant increase in revenue and backlog, coupled with strategic investments in owned and operated assets (IPP projects), aligns with the global push towards renewable energy integration and grid modernization. The focus on long-duration storage and diverse technologies (gravity-based, battery, green hydrogen) positions the company to address various market needs, while the Asset Vault initiative reflects a growing trend of financial institutions investing directly in renewable infrastructure to secure long-term, recurring revenue streams.

Comparison to Industry Standards

• The company's strategy to build, own, and operate energy storage projects (IPP model) is a common and increasingly favored approach in the renewable energy sector, allowing for recurring revenue streams similar to independent power producers in solar and wind.
• The acquisition of the 125MW / 1 GWh Stoney Creek BESS in Australia positions it as a significant player in the large-scale battery storage market, comparable in size to major utility-scale projects being developed by industry leaders globally.
• The expected annual recurring EBITDA contributions from projects like Cross Trails (~$10 million) and Stoney Creek (~$20 million) provide specific financial benchmarks for evaluating the profitability of individual energy storage assets within the company's portfolio, though direct comparisons to specific projects of competitors are not provided in the filing.

Stakeholder Impact

• Shareholders: Potential for increased shareholder value due to strong revenue growth, significant backlog, strategic capital infusion, and a clear path to recurring EBITDA from owned assets.
• Employees: Continued and potentially expanded employment opportunities as the company grows its project pipeline and operations.
• Customers: Benefit from the deployment of advanced, reliable grid-scale energy storage solutions, enhancing grid stability and renewable energy integration.
• Suppliers: Increased demand for components and services related to energy storage system construction and deployment.
• Creditors: Improved financial health and strategic funding may enhance the company's creditworthiness and ability to meet obligations.

Next Steps

• Closing of the $300 million Preferred Equity Investment, anticipated in the next 30-60 days.
• Hosting a Virtual Investor Day upon the closing of the Preferred Equity Investment to provide a comprehensive overview of the Asset Vault platform, project pipeline, financial projections, and long-term strategic vision.
• Anticipated receipt of $27 million in total net ITC proceeds in September.
• Commencement of battery deliveries for the Michigan project in Q4 2025.
• Beginning of construction for the Michigan project in Q1 2026.
• Commencement of construction for the Stoney Creek BESS in Australia in early 2026.
• Commercial operation of the Michigan project expected by Q4 2026.
• Completion of the Stoney Creek BESS in Australia expected in 2027.

Key Dates

Recommendation

The filing presents compelling evidence of strong operational execution and strategic growth. The 126% revenue increase and 120% backlog surge demonstrate robust demand and successful project delivery. The $300 million preferred equity investment for the Asset Vault initiative is a transformative development, securing capital for a significant pipeline of IPP projects expected to generate substantial recurring EBITDA. This shift towards an asset-ownership model, combined with improved Adjusted EBITDA and cash position, significantly de-risks future growth and provides a clear path to long-term profitability in a high-growth industry. Despite current net losses, the underlying business momentum and strategic funding make Energy Vault a highly attractive investment.
