Disclose the material risks to unaffiliated investors presented by taking the company public through a merger rather than an underwritten offering. These risks could include the absence of due diligence conducted by an underwriter that would be subject to liability for any material misstatements or omissions in a registration statement. 5. Revise your disclosure to show the potential impact of redemptions on the per share value of the shares owned by non-redeeming shareholders by including a sensitivity analysis showing a range of redemption scenarios, including minimum, maximum and interim redemption levels. 6. We note that certain shareholders agreed to waive their redemption rights. Please describe any consideration provided in exchange for this agreement. Cover Page 7.

This comment is also applicable to your unaudited pro forma statements of operations on pages 86 and 87 to disclose the historical earning per share data for Novus, as we note the loss per share data was not included. 15. Refer to the column, Combined Pro Forma, assuming maximum redemptions.

Also, disclose how the 2,177,460 shares were determined, as we note the filing discloses various amounts of shares subject to forfeiture, however, it is unclear which shares aggregate to this total number. 16. Please provide us with your computations of the historical book value per share for Energy Vault and Novus as of June 30, 2021, and clarify the description in subnote (2) regarding excluding preferred shares/shares outstanding. Also, disclose that the preferred shares pertain to Energy Vault, and clarify whether or not any outstanding preferred shares are assumed to have been converted into common shares in this calculation. Further, it appears the historical book value per share for both Energy Vault and Novus have been based on the weighted average shares of common stock, rather than the actual number of common shares outstanding at the balance sheet date.
