Risks and Price-Sensitive Issues

• Limited Operating History and Rapid Industry Evolution: Energy Vault’s young age and the nascent nature of the energy storage industry make it difficult to evaluate the company’s prospects, increasing uncertainty for investors.
• Continuous Engineering Refinement: The company’s products are under ongoing development, and there is no guarantee that all improvements will be successfully implemented on schedule, potentially impacting future revenues and margins.
• Tariffs and Trade Policy: Changes to U.S. tariff and import/export regulations, as well as international trade policies, could materially affect the cost and availability of key components, impacting project economics and profitability.
• Performance Risks: Energy Vault’s systems may not meet customer expectations or contractual performance requirements, leading to potential warranty claims, reputational damage, or loss of future business.

• Novel Technology Adoption: Products such as G-VAULT and B-VAULT are based on innovative applications of established principles. Customer hesitancy to adopt new technologies may slow market penetration and revenue growth.
• Internal Controls and Financial Reporting: Material weaknesses in internal control over financial reporting could adversely affect business operations and share price.
• Profitability and Losses: Energy Vault is an early-stage company with a history of losses and expects significant expenses and continued losses for the foreseeable future. Achieving profitability is uncertain.
• Backlog and Pipeline Risks: The company’s backlog, bookings, and developed pipeline may not accurately predict future revenue, and could be impacted by changes in equipment costs, tariffs, and currency fluctuations.
• Geopolitical and Regulatory Risks: Operations in multiple geographies and engagement with critical infrastructure introduce risks related to capital controls, payment collection, and sudden regulatory changes.
• Lengthy Sales Cycles: Energy Vault’s products involve long sales and installation cycles, which may result in significant expenses without guaranteed offsetting revenues.
