Management Comments

• "The successful financing of our Cross Trails BESS project represents another significant milestone in executing our 'Own & Operate' strategy, delivering strong returns that will generate predictable, high margin and recurring revenue streams."
• "Following our recent Calistoga Resiliency Center project financing and the acquisition of the 125 MW/1 GWh Stoney Creek BESS in Australia, this latest financing close demonstrates our ability to attract premium financing partners while building a diversified portfolio of attractive energy storage assets across the globe."
• "With an attractive mid-teen levered IRR and a 10-year offtake agreement in place, the Cross Trails BESS is another example of our commitment to creating long-term shareholder value through strategic energy storage asset ownership and operation in key growth markets."

Industry Context

This financing highlights the growing investment in grid-scale energy storage solutions, particularly battery energy storage systems (BESS), which are crucial for supporting renewable energy integration and improving grid resiliency. The ERCOT market in Texas is a key growth area for such projects, driven by increasing renewable penetration and the need for flexible grid assets. Energy Vault's 'Own & Operate' strategy positions it to capitalize on this trend by developing and owning these assets, generating recurring revenue streams, and attracting specialized project financing.

Comparison to Industry Standards

• The Cross Trails BESS (57 MW/114 MWh) is a significant project, comparable in strategic importance to Energy Vault's previously financed Calistoga Resiliency Center micro-grid project in California, which secured $28 million in financing.
• The financing aligns with Energy Vault's global 'Own & Operate' strategy, as evidenced by the recent acquisition of the 125 MW/1,000 MWh Stoney Creek BESS in Australia.
• The 10-year offtake agreement with Gridmatic for Cross Trails is notable as the first physically settled revenue floor contract for a BESS in the ERCOT market, potentially setting a new standard for risk mitigation and revenue predictability in the region.
• The reported mid-teen levered Internal Rate of Return (IRR) of approximately 15% is presented as attractive, suggesting it meets or exceeds typical investor expectations for energy storage infrastructure projects of this scale and risk profile.

Legal Proceedings

• Existing Litigation mentioned in Schedule 4.07 and Section 7.01(n) that needs to be settled or resolved by January 31, 2026, with related Scheduled Liens released by the same date.
