THIS FIRST AMENDMENT TO SECURITIES PURCHASE AGREEMENT (this “Amendment”), dated as of June 29, 2026, is between ENERGY VAULT HOLDINGS, INC., a company incorporated under the laws of the State of Delaware, with principal executive offices located at 4165 East Thousand Oaks Blvd., Suite 100, Westlake Village, CA, 91362 (the “Company”), and YA II PN, LTD., in its capacity as a “Buyer” under the Original SPA referred to below (the “Buyer”).

WITNESSETH

WHEREAS, the Company and the Buyer are parties to that certain Securities Purchase Agreement, dated as of May 18, 2026 (the “Original SPA”; and the Original SPA, as amended by this Amendment, the “SPA”); capitalized terms used but not otherwise defined herein shall have the meanings ascribed to such terms in the SPA), with respect to the issuance of the AR Convertible Debenture, issued on May 18, 2026 in the original principal amount of $42,000,000, with Number NRGV-AR1 (the “Initial AR Convertible Debenture”);

WHEREAS, the Original SPA capped the aggregate principal amount of Convertible Debentures issued thereunder to $75,000,000 pursuant to Section 1(a) thereof;

WHEREAS, pursuant to Section 12 of the Original SPA, and subject to the terms and conditions set forth in this Amendment, the Company and the Buyer desire to amend the Original SPA to, among other things, permit the Company to issue and sell to the Buyer identified on the amended Schedule I attached hereto as Exhibit C, $38,000,000 of additional principal (the “Additional Principal Amount”), which shall be memorialized by an Amended and Restated AR Convertible Debenture in the form attached hereto as Exhibit A (the “Amended and Restated AR Convertible Debenture”); and

WHEREAS, contemporaneously with the execution and delivery of this Amendment, the Company is delivering an updated Irrevocable Transfer Agent Instructions (the “Updated Irrevocable Transfer Agent Instructions”) to its transfer agent in the form attached hereto as Exhibit B.

AGREEMENTS

NOW, THEREFORE, in consideration of the premises and the mutual covenants contained herein and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Company and each Buyer hereby agree as follows:

No financing statement or other public notice with respect to all or any part of the Collateral is on file or of record in any public office, except filings evidencing Permitted Liens.

(a)References. Upon the effectiveness of this Amendment, each reference in the SPA to “this Agreement,” “hereunder,” “hereof,” “herein” or words of like import shall mean and be a reference to the SPA, as amended hereby. The term “Transaction Documents” as

8


defined in Section 3(b) of the SPA shall include (in addition to the Transaction Documents described in the SPA) this Amendment and any other agreements, instruments or other documents executed in connection herewith.

(b)No Waiver. The Buyer’s failure, at any time or times hereafter, to require strict performance by the Company of any provision or term of the SPA, this Amendment, or the other Transaction Documents shall not waive, affect or diminish any right of the Buyer hereafter to demand strict compliance and performance herewith or therewith. Any suspension or waiver by the Buyer of a breach of this Amendment or any Event of Default under the SPA shall not, except as expressly set forth in a writing signed by the Buyer, suspend, waive or affect any breach of this Amendment or any Event of Default under the SPA, whether the same is prior or subsequent thereto and whether of the same or of a different kind or character. None of the undertakings, agreements, warranties, covenants, and representations of the Company contained in this Amendment, shall be deemed to have been suspended or waived by the Buyer unless such suspension or waiver is (i) in writing and signed by the Buyer and (ii) delivered to the Company. In no event shall the Buyer’s execution and delivery of this Amendment establish a course of dealing among the Buyer, the Company, or any other obligor, or in any other way obligate the Buyer to hereafter provide any consents, amendments, or waivers with respect to the SPA or other Transaction Documents. The terms and provisions of this Amendment shall be limited precisely as written and shall not be deemed (x) to be a consent to any waiver, amendment or modification of any other term or condition of the SPA or of any of the Transaction Documents (except as expressly provided herein); or (y) to prejudice any right or remedy which the Buyer may now have under or in connection with the SPA or any of the Transaction Documents. Neither this Amendment nor any uncertainty or ambiguity herein shall be construed or resolved against the Buyer, whether under any rule of construction or otherwise.

(c)Full Force and Effect. Except as expressly provided herein, the SPA and all other Transaction Documents shall remain in full force and effect against the Company and are hereby ratified and confirmed by the Company. This Amendment shall not be construed as a waiver or amendment of any other provision of the SPA or for any purpose except as expressly set forth herein. Notwithstanding the foregoing, in the event of a conflict between the provisions of this Amendment and the SPA, the terms of this Amendment shall supersede such provisions and shall control.

8.Severability; Amendments. Whenever possible, each provision of this Amendment shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Amendment shall be prohibited by or invalid under applicable law, such provision shall be ineffective only to the extent of such prohibition or invalidity, without invalidating the remainder of such provisions or the remaining provisions of this Amendment. The parties hereto have participated jointly in the negotiation and drafting of this

9


Amendment. In the event an ambiguity or question of intent or interpretation arises, this Amendment shall be construed as if drafted jointly by the parties hereto, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any of the provisions of this Amendment. This Amendment may be amended or modified only by mutual agreement of the parties evidenced in writing and signed by the party to be charged therewith.

9.Incorporation by Reference. Sections 9(a) (Governing Law), 9(b) (Jurisdiction; Venue; Service), 9(c) (Waiver of Jury Trial), 9(d) (Counterparts), 9(e) (Headings; Gender), 9(f) (Entire Agreement, Amendments), 9(g) (Notices), 9(h) (Successors and Assigns), 9(j) (No Strict Construction) of the SPA are incorporated herein, mutatis mutandis, as if fully set forth herein with references to this “Agreement” to be understood to refer to the SPA, as amended by this Amendment.
