Explanation of Responses:

( 1 )On July 23, 2021, the Reporting Person sold 20,000 shares to a third party for $1.8 million in aggregate consideration pursuant to a stock purchase agreement (the "SPA"). The SPA provided that, for no further consideration, the Reporting Person would transfer additional shares to the third party purchaser if the initial public listing price of Energy Vault, Inc., a Delaware corporation ("Legacy Energy Vault") did not achieve a certain minimum share price target, and the Reporting Person agreed to transfer an additional 9,500 shares of Legacy Energy Vault's common stock to the third party purchaser. ( 2 )On February 11, 2022, the Issuer's business combination with Legacy Energy Vault closed (the "Closing"), and each share of Legacy Energy Vault's common stock was converted into the right to receive 6.7735 shares of the Issuer's common stock pursuant to the terms of that certain Business Combination Agreement and Plan of Reorganization, dated September 8, 2021, by and between Issuer, NCCII Merger Corp., a wholly owned subsidiary of the Issuer, and Legacy Energy Vault. This did not meet the minimum share price target and on July 6, 2022, the Reporting Person transferred 64,348 shares to the third party purchaser (which reflected the effect of the exchange ratio in the merger), which shares are subject to same transfer restrictions provided by the lock-up agreements that the Issuer entered into with the third party purchaser and certain other equityholders of the Issuer and Legacy Energy Vault in connection with the Closing.
