8-K: Energy Vault Reports Strong Backlog Growth, Transitions to Asset Ownership Strategy in Q4 and Full Year 2024 Results

Energy Vault's revenue backlog surged 90% to $660 million in Q4 2024, driven by growth in Australia and new US customers, as the company shifts towards asset ownership with long-term offtake agreements.

Summary

• Energy Vault reported its Q4 and full year 2024 financial results, highlighting a significant increase in contract revenue backlog, which rose 90% to $660 million from the prior quarter and more than quadrupled year-over-year.
• This growth is attributed to strength in Australia, new US IPP and utility customers, and a strategic shift towards asset ownership with long-term offtake agreements.
• The company is actively executing projects in Australia, including the acquisition of the 1.0 GWh Stoney Creek BESS.
• Energy Vault's developed pipeline remains robust at $2.1 billion, adjusted for prevailing battery prices, tariffs, and foreign exchange rates.
• Q4 2024 revenue was $33.5 million, primarily from US storage equipment deliveries, while full-year 2024 revenue reached $46.2 million.
• The company chose to retain ~$100 million in projects on its balance sheet with long-term tolling and offtake agreements, expecting high margin 80%+ EBITDA streams upon completion.
• Q4 2024 GAAP gross margin improved to 7.7%, doubling from 3.4% a year ago, and full-year 2024 GAAP gross margins significantly improved to 13.4% from 5.1% the previous year.
• Project financing for the Calistoga Green Hydrogen project received a binding funding commitment in March, with expected closure in April 2025, returning ~$28 million to the balance sheet.

• Energy Vault anticipates a 4-6x increase in revenue for 2025, projecting $200 to $300 million, reflecting growth in Australia and the US market.
• This outlook is tempered by the conversion of build and transfer revenue projects to own and operate assets (estimated ~$150 million impact) and the continued downward trend in global lithium-ion battery prices and increased tariffs in the U.S. (estimated ~$75 million impact).

Industry Context

Energy Vault's shift towards owning and operating energy storage assets aligns with the growing trend of energy companies seeking to generate recurring revenue streams through long-term contracts. The company's focus on sustainable energy storage solutions positions it well in the context of the global clean energy transition.

Comparison to Industry Standards

• Energy Vault's revenue backlog growth of 90% quarter-over-quarter is significant compared to competitors in the energy storage sector.
• Companies like Fluence and Tesla also focus on grid-scale energy storage, but Energy Vault differentiates itself with its gravity-based storage technology.
• The projected 4-6x revenue increase for 2025 is ambitious and would position Energy Vault as a high-growth player in the industry, if achieved.
• The company's gross margin improvement is a positive sign, but it still lags behind some established players in the energy sector.
