[Form 4/A] Energy Vault Holdings, Inc. Amended Insider Trading Activity

Rhea-AI Filing Summary

Energy Vault Holdings, Inc. (NRGV) reporting person Dylan Hixon filed an amended Form 4 correcting his original August 14, 2025 filing. The amendment states Mr. Hixon purchased 20,000 shares of common stock on 08/14/2025 at a price of $1.4956 per share, and that those shares were reported in error as directly owned when they are indirectly held through Arden Road Investments LLC. Following the reported purchase, the filing shows 880,065 shares beneficially owned.

The amendment explains the original Form 4 misstated the ownership form and overstated the amount acquired due to a typographical error. The filing also discloses Mr. Hixon is sole trustee of the Dylan Trust under the JMH-ICH Lex Trust, which holds shares in Arden Road Investments LLC, and that he disclaims beneficial ownership except to the extent of pecuniary interest.

Insights

Securities Analyst

TL;DR: Amendment corrects reporting errors; shows an insider purchase of 20,000 shares and clarifies indirect ownership of 880,065 shares.

The amended Form 4 is procedural but relevant: it corrects the ownership form from direct to indirect and fixes an overstated acquisition amount. The corrected data confirms an insider purchase at $1.4956 for 20,000 shares, and reports total beneficial ownership of 880,065 shares attributable indirectly through Arden Road Investments LLC. For investors, the filing provides clarity on the insider's relationship to the shares and the precise transaction size and price. The disclosure of trustee status and the disclaimer of beneficial ownership except for pecuniary interest are standard and limit direct control assertions.

Corporate Governance Expert

TL;DR: The amendment addresses compliance and transparency by correcting reporting errors; no new derivative or additional transactions disclosed.

The document is an amendment focused on accuracy and compliance with Section 16 reporting requirements. It clarifies that the securities are held indirectly via an entity tied to a trust for which Mr. Hixon is sole trustee. The filing contains no derivative transactions and no additional changes to ownership beyond correcting the prior misreporting. The corrective filing reduces ambiguity about beneficial ownership and aligns the record with reporting rules.

Explanation of Responses:

1. This amendment on Form 4A is being filed to correct an error in reporting on the Reporting Persons previously filed Form 4 filed on August 14, 2025. The previously filed 4 mistakenly a. reported the Ownership Form in Column 6 of Table I as Direct rather than Indirect and accordingly did not describe the Nature of Indirect Beneficial Ownership in Column 7 of Table I and b. overstated the Amount of Securities Acquired in Column 4 of Table I due to a typographical error.

2. The shares are purchased in one transaction at a price given in Column 4.

3. Mr. Hixon is the sole trustee of the "Dylan Trust under the JMH-ICH Lex Trust" which holds shares in Arden Road Investments LLC. Mr. Hixon may be deemed to have beneficial ownership of the securities held by the Dylan Trust. Mr. Hixon disclaims beneficial ownership of such securities except to the extent of his pecuniary interest therein.
