Energy Vault has since expanded its portfolio to include battery energy storage systems (BESS) and green hydrogen solutions, all of which are managed by its advanced energy management software platform, VaultOS. This diversification, implemented in 2022, has allowed the company to better serve the evolving needs of its customers in the rapidly changing renewable energy sector.

Since its inception, Energy Vault has rapidly expanded its global footprint, with projects and partnerships spanning North America, Europe, Asia, and Australia. In 2022, the company achieved another significant milestone through its reverse merger and subsequent public listing on the New York Stock Exchange, providing it with the necessary capital and visibility to accelerate its growth strategy.

Financial Performance and Liquidity:

Energy Vault's financial performance has been marked by significant investments in research and development, as well as the buildout of its project pipeline. For the fiscal year 2023, the company reported revenue of $341.54 million, a substantial increase from the $145.88 million recorded in 2022. However, the company has yet to achieve profitability, reporting a net loss of $98.44 million in 2023, compared to a net loss of $78.30 million in 2022. The company's operating cash flow (OCF) for 2023 was negative $92.66 million, while free cash flow (FCF) stood at negative $129.20 million.
