About Energy Vault Holdings, Inc.

Energy Vault Holdings, Inc. is a U.S.-based company listed on the NYSE/NASDAQ in the United States, focused on grid-scale energy storage and, more recently, software-enabled and AI-oriented energy infrastructure. The company was built around a clear strategic thesis: help utilities, independent power producers, and large industrial users integrate more renewable energy while preserving grid reliability and dispatch flexibility. Its operating headquarters are in Westlake Village, California, and the group has an international footprint with projects and commercial activity extending beyond the U.S. market. ([energyvault.com](https://www.energyvault.com/about?utm_source=openai)) Energy Vault’s competitive position is based on a differentiated technology stack in a highly competitive storage industry. The company develops, deploys, and operates utility-scale energy storage solutions, including battery-based systems, gravity-based storage, and green-hydrogen storage technologies. These solutions are supported by a technology-agnostic energy management software and integration platform designed to optimize dispatch, reliability, and value capture. This broad portfolio allows Energy Vault to address multiple use cases, from short-duration balancing to long-duration and multi-day storage, a segment that is becoming increasingly important as renewable penetration rises and grid flexibility requirements intensify. ([investors.energyvault.com](https://investors.energyvault.com/overview/?utm_source=openai)) From a corporate history perspective, Energy Vault has increasingly emphasized an “Own & Operate” model since 2024. That strategy aims to generate recurring, higher-margin tolling-style revenues through asset ownership and management, complementing the company’s earlier emphasis on technology deployment and equipment sales. For investors, this is a meaningful shift because it potentially improves revenue quality and visibility, but it also requires capital discipline and successful project execution. Over 2025 and 2026, the company strengthened its financial structure through targeted financing actions, including a convertible note transaction and a preferred equity investment, both intended to support growth and balance-sheet flexibility.

In February 2026, the company announced strategic agreements with Peak Energy and Crusoe, underscoring its growing relevance in AI-driven power demand and data-center infrastructure. It also announced a move into Japan through the acquisition of an 850 MW storage portfolio, and disclosed a 100 MW / 870 MWh long-term energy service agreement in Australia, reinforcing its international ambitions. Overall, Energy Vault remains a mid-cap, innovation-led energy transition company whose equity story depends on converting its technology pipeline and partnerships into durable, cash-generating operations.
