Energy Vault Holdings files its annual report describing how it is evolving from a pure equipment and licensing provider into a mix of third‑party sales and “Own & Operate” energy storage projects. The company launched its Asset Vault platform with a $300 million preferred equity commitment from Orion Infrastructure Capital to fund a targeted 1.5 GW storage portfolio across the U.S., Australia, and Europe.
Energy Vault highlights initial owned assets like the Cross Trails battery system in Texas and the Calistoga Resiliency Center in California, plus Australian projects such as Stoney Creek and the Ebor BESS. It also outlines an entry into AI infrastructure through modular data centers under a framework agreement with Crusoe, and discusses competitive dynamics, extensive regulatory and tax-credit changes, ESG initiatives, human capital, and detailed risk factors tied to technology performance, supply chain, policy shifts, and financing.
Energy Vault Holdings reported a breakout 2025 with revenue of $203.7 million, up over 340% year-over-year and within its original guidance range. Q4 2025 revenue jumped to $153.3 million, while contract revenue backlog reached $1.3 billion as of December 31, 2025.
GAAP gross profit rose to $48.0 million for 2025, lifting gross margin to 23.6% from 13.4%. The company still posted a 2025 GAAP net loss of $103.6 million, but Q4 adjusted EBITDA turned positive at $9.8 million and Q4 adjusted net income reached $3.7 million.
Cash and restricted cash climbed to $103.4 million at year-end, helped by a $150 million senior convertible notes offering and a $300 million preferred equity fund supporting its Asset Vault platform. Contracted, operating and in-construction capacity grew from 65 MW to 540 MW, and 2026 guidance calls for $225–300 million in revenue, gross margin of 15–25% and year-end cash of $150–200 million.
