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 March 6, 2026, NPEH exchanged 3,000,000 Class A Units of NET Power Operations LLC for 3,000,000 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 3,000,000 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 90.9% 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. Damian R. Beauchamp ("Mr. Beauchamp") independently indirectly owns approximately 63.72% of 8 Rivers, and Mr. Beauchamp directly owns approximately 3.83% of 8 Rivers. Accordingly, Mr. Beauchamp may be deemed the indirect beneficial owner of the securities owned by NPEH to the extent of his pecuniary interest therein. Mr. Beauchamp disclaims beneficial ownership of any such securities, except to the extent of his or her pecuniary interest therein, if any, and this report shall not be deemed an admission that Mr. Beauchamp is the beneficial owner of such securities for purposes of Section 16 or otherwise.

5. This amendment is being filed to correct an administrative error in the Form 4 filed on March 10, 2026 (the "Original Form 4") and report the 3,000,000 Class A Units of NET Power Operations LLC that were converted into an equal number of shares of the Issuer's Class A Common Stock as being disposed of by the Reporting Person. The Original Form 4 inadvertently omitted such Class A Units from Table II.
