DURHAM, N.C.--(BUSINESS WIRE)—August 11, 2025--Net Power Inc. (NYSE: NPWR) (“Net Power” or the “Company”) today announced its financial and operational results for the second quarter ended June 30, 2025.

•Integrated Product Configuration: Completed techno-economic analysis for integrating cost-effective gas turbine capacity (50MW-200MW) into Net Power projects. Results indicate significant operational, economic, and commercial synergies. This configuration will be implemented at Project Permian, targeting a levelized cost of energy (LCOE) below $100/megawatt hour (MWh).

•SN1 Cost Reduction: Identified further cost reductions for SN1, with projected total installed cost of $1.6-1.9 billion while preserving product performance.

•OBBBA Enhances Economics: Recent tax legislation, including expanded 45Q credits for Class II sequestration and reinstated bonus depreciation, improves project economics, yielding approximately $20/MWh LCOE improvement at Project Permian.

•Robust financial position: Ended the quarter with approximately $475 million in cash, cash equivalents and investments.

Danny Rice, President & Chief Executive Officer of Net Power, stated, “Over the past several months, we have conducted an in-depth engineering, operational, and commercial analysis to optimize Net Power’s deployment amid unprecedented demand growth for reliable power generation. Today, we are excited to share the initial positive results, including a strategy that integrates simple cycle gas turbines into the project design, unlocking significant operational synergies through heat integration with our Net Power Cycle. This configuration allows us to deliver power sooner and at a lower cost per unit of power by installing gas turbines first and then integrating that equipment directly with the Net Power Cycle. We believe this solution perfectly aligns with the market’s need for reliable power today with the embedding of credible pathways to decarbonize over time—we are seeing this prioritization directly from customers. We plan to demonstrate this integrated product at Project Permian, where LCOE has improved by over 33 percent, driven by the integrated product synergies, ongoing cost reduction efforts, and recent enhancements to 45Q. The world needs the reliable, clean electricity that Net Power can provide and that can catalyze a decarbonized power system. The integrated product gives us the best pathway to get our first projects built and deliver on the technology’s promise.”

At its La Porte test facility, the Company completed site repairs and resumed technology validation work, achieving over 150 hours of testing in July. Phase 1 testing is expected to be completed in 2025 and the Company expects to begin phase 2 testing this year with completion in early 2026. Preparations continue for testing Phases 3 and 4, expected to be completed in 2026 and 2027, respectively.

Net Power continued the development of its MISO project, which remains on track for early deployment. Net Power’s 300MW interconnect application is subject to the progress timeline of the MISO DPP-2023 cycle. The Company’s sequestration providers are progressing their Class VI sequestration applications through the EPA’s Class VI permit process. Similar to Project Permian, Net Power is evaluating the integrated product configuration at this location.
