Explanation of Responses:

1. The Class A Units of NET Power Operations LLC are exchangeable into shares of the Issuer's Class A Common Stock or, at the Issuer's election, cash, on a one-for-one basis and have no expiration date. On September 25, 2024, NPEH, LLC ("NPEH") exchanged 1,015,000 Class A Units of NET Power Operations LLC for 1,015,000 shares of the Issuer's Class A Common Stock.

2. For each Class A Unit of Net Power Operations LLC, NPEH owns a corresponding share of Class B Common Stock of the Issuer. Upon the exchange of 1,015,000 Class A Units of Net Power Operations LLC, an equal number of shares of Class B Common Stock of the Issuer held by NPEH, which have no economic value, were cancelled.

3. As manager and holder of approximately 91.4% of the outstanding equity in NPEH, 8 Rivers Capital, LLC ("8 Rivers") may be deemed to be a beneficial owner of the securities directly owned by NPEH. 8 Rivers disclaims beneficial ownership of any such securities, except to the extent of its pecuniary interest therein, if any, and this report shall not be deemed an admission that 8 Rivers is the beneficial owner of such securities for purposes of Section 16 or otherwise.

4. SK Inc. ("SK") indirectly beneficially owns 100.0% of each of Tillandsia, Inc. ("Tillandsia"), Areca, Inc. ("Areca") and Chamaedorea, Inc. ("Chamaedorea").

SK disclaims beneficial ownership of any such securities, except to the extent of its pecuniary interest therein, if any, and this report shall not be deemed an admission that SK is the beneficial owner of such securities for purposes of Section 16 or otherwise.
