On April 14, 2025, it was determined that Brian Allen and Akash Patel will no longer serve as President and Chief Operating Officer and Chief Financial Officer, respectively, of Net Power Inc. (the “Company”), effective as of April 15, 2025. Further, Mr. Allen and Mr. Patel will cease to be employed by Net Power Management, LLC, a subsidiary of the Company, effective as of May 1, 2025 (the “Effective Date”). In accordance with the terms and conditions of the Company’s First Amended & Restated Executive Severance Plan (the “Severance Plan”) and outstanding equity award agreements, (a) Mr. Allen and Mr. Patel will each be entitled to receive a cash severance payment equal to the sum of the following amounts: (i) an amount equal to the sum of each of their (A) current base salary and (B) the average of the actual annual bonuses paid to Mr. Allen and Mr. Patel with respect to 2023 and 2024, (ii) a pro-rated portion of their respective target annual bonuses for 2025, and (iii) an amount equal to 12 months of the premiums for their respective group health plan coverages (including coverage for eligible dependents) under the Company’s group health plans and (b) 56,670 and 50,403 outstanding restricted stock units (“RSUs”) subject to time-based vesting conditions held by Mr. Allen and Mr. Patel, respectively, will vest as of the Effective Date, and (c) a pro-rated portion of the outstanding performance share units and RSUs subject to operations-based vesting conditions held by Mr. Allen and Mr. Patel will remain outstanding and eligible to vest if the applicable performance criteria or milestone events are achieved, in each case subject to Mr. Allen and Mr. Patel entering into a release of claims in favor of the Company and their continued compliance with the terms of the Severance Plan, including the restrictive covenant obligations thereunder. The foregoing description of the severance benefits is not complete and is qualified in its entirety by reference to the copy of the Separation and Release Agreements to be entered into by each of Mr. Allen and Mr. Patel, which will be filed as exhibits to the Company’s Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2025.

Also on April 14, 2025, the Company appointed Daniel J. Rice IV, the Company’s Chief Executive Officer, as President and Interim Chief Financial Officer and Marc Horstman as Chief Operating Officer. Biographical information for Mr. Rice can be found in the Company’s definitive proxy statement on Schedule 14A, which was filed with the Securities and Exchange Commission (the “SEC”) on April 26, 2024 (the “2024 Annual Meeting Proxy Statement”), and is incorporated herein by reference. In connection with the foregoing change, no new compensatory arrangements were or will be entered into with Mr. Rice, who will continue to also serve as the Company’s Chief Executive Officer and as a member of the Company’s board of directors.

As an executive officer of the Company, Mr. Horstman will participate in the Severance Plan, the material terms of which are summarized in the 2024 Annual Meeting Proxy Statement.

Additionally, Mr. Horstman and the Company will enter into the standard form indemnification agreement that the Company has entered into with each of its executive officers and directors, which provides the indemnitees with contractual rights to indemnification, and expense advancement and reimbursement, to the fullest extent permitted under the Delaware General Corporation Law, subject to certain exceptions contained in those agreements. The foregoing summary of the indemnification agreement does not purport to be complete and is qualified in its entirety by reference to the form of indemnification agreement, which was filed as Exhibit 10.4 to the Company’s Current Report on Form 8-K filed with the SEC on June 14, 2023 and which is incorporated herein by reference. At this time, any changes to Mr. Horstman’s compensation in connection with his appointment as Chief Operating Officer have not been determined. The Company will file an amendment to this Current Report on Form 8-K disclosing any compensation adjustments made in connection with Mr. Horstman’s appointment as Chief Operating Officer if and when they are determined.

There are no family relationships between either Mr. Rice or Mr. Horstman, on the one hand, and any director or executive officer of the Company, on the other hand, that are required to be disclosed pursuant to Item 401(d) of Regulation S-K, and except as previously disclosed with respect to Mr. Rice in the 2024 Annual Meeting Proxy Statement under “Certain Relationships and Related Party Transactions,” which is incorporated herein by reference, there are no current or proposed transactions in which Mr. Rice or Mr. Horstman has or will have a direct or indirect material interest and in which the Company is or will be a participant that require disclosure pursuant to Item 404(a) of Regulation S-K. In addition, there are
