Item 5.02. Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers

On April 10, 2026, Ned Leland (Lee) Shuman was appointed as Chief Financial Officer of Net Power Inc. (the “Company”), effective as of April 13, 2026, replacing the Company’s interim Chief Financial Officer, Daniel J. Rice IV. Mr. Rice will continue to serve as the Company’s Chief Executive Officer, as well as its principal financial officer through the date of filing of the Company’s Quarterly Report on Form 10-Q for the three months ended March 31, 2026, whereupon Mr. Shuman will assume the role of the Company’s principal financial officer.

Mr. Shuman, age 56, is a power-sector finance and strategy executive with more than 25 years of experience in acquisitions, divestitures, restructurings, project development, and financings. Mr. Shuman most recently served as Head of Power Finance at Javelin Global Commodities from April 2024 to April 2026, where he led underwriting and diligence for strategic power investments and originated and evaluated thermal and renewable opportunities. From 2020 to April 2024, Mr. Shuman served as Chief Financial Officer of WattBridge Energy, where he led more than $1.6 billion of senior secured financings and raised $425 million of mezzanine and HoldCo capital for a 2.4 GW ERCOT gas portfolio.

Mr. Shuman received a J.D. from the University of Georgia School of Law, an M.Tax and an M.B.A. in Finance from Georgia State University, and a B.A. from Emory University.

As a result of Mr. Shuman’s appointment as Chief Financial Officer of the Company, effective April 13, 2026, the Company’s board of directors (the “Committee”) approved for Mr. Shuman (i) an annual base salary of $420,000, (ii) eligibility to earn an annual cash bonus under the Company’s short-term incentive plan (the “STIP”) with a target value of 60% of Mr. Shuman’s annual base salary for each year that Mr. Shuman is employed by the Company (subject to the terms and conditions of the STIP), (iii) eligibility to earn an annual equity award under the Company’s 2023 Omnibus Incentive Plan (the “LTIP”) with a target value of 180% of Mr. Shuman’s annual base salary for each year that Mr. Shuman is employed by the Company (subject to the terms and conditions of the LTIP), (iv) the grant of restricted stock units (“RSUs”) pursuant to the LTIP with a grant date fair value of $800,000 that will vest three years after the date of grant (subject to Mr. Shuman’s continued employment with the Company and the terms of the LTIP), (v) a $100,000 cash bonus, and (v) participation in those benefit plans and programs of the Company available to similarly situated executives.

As an executive officer of the Company, Mr.Shuman will participate in the Company’s Second Amended and Restated Executive Severance Plan (the “Severance Plan”), a copy of which was filed as Exhibit 10.1 to the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025 and which is incorporated herein by reference. Additionally, Mr. Shuman 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.

There are no understandings between Mr. Shuman and any other persons pursuant to which he was selected to serve as the Company’s Chief Financial Officer. There are no family relationships between Mr. Shuman and any director or executive officer of the Company.
