Major milestone of fourth Asset Vault project now under construction, ‘safe harbored' and FEOC compliant as part of broader investment program executed in Q4 2025 for multiple projects

Previously acquired from Royal Dutch Shell's subsidiary Savion, SOSA Energy Center estimates commercial operation by Q2 2027 with expected total revenue of $350M+ over the technical life, or ~$17-20 million of recurring annual, high margin revenues

Asset Vault successfully commenced off-site construction in Q4 2025 of three additional projects in its near-term pipeline with expected commercial operation between Q4 2027 and Q4 2028

Increased cash and liquidity ~65% in Q4 2025 to over $100 million -- above the high end of the guidance range – well positioned to execute on the Company's energy asset management strategy

Energy Vault Holdings, Inc. (NYSE:NRGV) ("Energy Vault"), a leader in sustainable, grid-scale energy storage solutions, today announced the start of construction of the SOSA Energy Center, a 150 MW/300 MWh battery energy storage system (BESS) located in Madison County, Texas. The project, originally developed by Savion, a subsidiary of Shell plc, was formally acquired by Energy Vault in Q4 2025 under its Asset Vault platform, and is expected to achieve commercial operation by Q2 2027.

The construction milestone represents a significant advancement in Energy Vault's "Own & Operate" asset management strategy and demonstrates the company's commitment to rapid deployment of bankable energy infrastructure capable of delivering dependable recurring revenues. The SOSA Energy Center is the first project to begin construction under Energy Vault's Asset Vault investment platform, which is supported by the $300 million preferred equity investment from Orion Infrastructure Capital (OIC). Energy Vault remains well positioned from a cash and liquidity perspective to execute on the company's broader ‘Own & Operate' strategy, ending 2025 with total cash of over $100 million, up 65% over the prior quarter and above the high-end of our guidance range

The 150 MW/300 MWh BESS is strategically positioned within the ERCOT North market and will leverage Energy Vault's third-generation B-VAULT™ DC product, enabling rapid deployment at competitive costs while providing enhanced system availability. Upon completion, the project will deliver critical grid support and renewable integration capacity to Texas's dynamic energy landscape, with an expected 6-8-year offtake agreement currently in advanced negotiations with an investment-grade counterparty.
