Item 1.01 Entry into a Material Definitive Agreement.

On August 14, 2026, EV Gen Set 1, LLC, a Delaware limited liability company (the “Borrower”) and EV Gen Set I HoldCo, LLC, a Delaware limited liability company (“Holdings”), each a subsidiary of Energy Vault Holdings, Inc. (the “Company”), entered into a credit agreement (the “Credit Agreement”) with CSC Delaware Trust Company, as administrative agent and collateral agent, and each of the lenders party thereto. The Credit Agreement provides for a senior secured term loan facility in an aggregate principal amount of approximately $137.5 million. The proceeds of the term loan facility are to, among other things, fund the purchase of power generation equipment and related installation and commissioning services pursuant to an equipment supply agreement (the “Equipment Supply Agreement”). Loans under the facility are funded in installments, drawn from time to time to fund payments as they become due under the Equipment Supply Agreement. Loans under the facility bear interest at a rate per annum equal to (a) with respect to any SOFR Loan, (i) 6.75% for each day occurring on or prior to December 31, 2026 and (ii) 7.50% for each day occurring thereafter; and (b) with respect to any ABR Loan, (i) 5.75% for each day occurring on or prior to December 31, 2026 and (ii) 6.50% for each day occurring thereafter. The facility matures on January 2, 2028. The Borrower may prepay the loans at any time upon three Business Days’ prior written notice, subject to payment of accrued interest, breakage costs and a repayment premium as set forth in the Credit Agreement. Mandatory prepayments are required upon the occurrence of certain customary events, including the receipt of (a) insurance or condemnation proceeds, (b) asset sale proceeds, (c) proceeds from the incurrence of non-permitted indebtedness, (d) proceeds from equity issuances by the Borrower (other than certain permitted equity contributions to fund equipment payments), and (e) proceeds from the Advance Payment Bond. The obligations of the Borrower under the Credit Agreement are guaranteed by Holdings and secured by a first priority security interest in substantially all of the assets of the Borrower and Holdings, including the contract rights under the Equipment Supply Agreement, accounts and related collateral, as well as the membership interests in the Borrower. The Credit Agreement contains customary affirmative and negative covenants for equipment financings of this type, including limitations on additional indebtedness, liens, asset sales, investments, affiliate transactions, and distributions, as well as customary provisions relating to the remarketing of the equipment financed thereunder. Borrower is also required to maintain a debt service reserve account containing an amount sufficient to cover three months of debt service, deliver certain financial and other reports, and comply with applicable laws and permits. The Credit Agreement also includes customary representations and warranties, indemnification provisions and requirements for the maintenance of insurance and compliance with applicable laws and permits. Capitalized terms used herein and not otherwise defined have the meanings ascribed to them in the Credit Agreement.

The foregoing description of the Credit Agreement is qualified in its entirety by reference to the full text of the Credit Agreement, which is attached as Exhibit 10.1 to this Current Report on Form 8-K and incorporated herein by reference.
