NET Power Inc. reported a sharp increase in loss driven by a strategic shift away from its Oxy-Combustion Cycle technology and toward natural-gas power projects designed to accommodate future carbon capture. For the quarter ended June 30, 2026, consolidated net loss was $206.9 million, including a non-cash impairment of $193.7 million on developed technology, the La Porte Demonstration Facility and related assets. Net loss attributable to NET Power Inc. was $80.3 million, or $0.91 per Class A share.
Operating expenses excluding impairment declined meaningfully year over year, with research and development, project development, and general and administrative costs all lower as Oxy-Combustion work and the SN1 project were wound down. The Oxy-Combustion Cycle has been indefinitely suspended, and the related assets are fully impaired and carried at no value.
The company is now focused on Project Permian in West Texas, initially as a natural gas project without carbon capture. A final investment decision is no longer expected in 2026, and no new target date has been set. As of June 30, 2026, total assets were $338.3 million, including cash, cash equivalents, restricted cash and available-for-sale securities totaling $309.6 million, against $25.5 million of liabilities and $229.3 million of redeemable non-controlling interests. Net cash used in operating activities for the first half of 2026 was $60.7 million.
Net Power Inc. recalibrates its commercial strategy toward fast-to-deploy, unabated natural gas power generation focused on speed-to-power, reliability, and scale, with carbon capture designed to be added in later phases as economics and customer demand support it. The company continues commercial discussions with prospective power offtakers for Project Permian and other sites and has contracted two modular gas turbine generator sets with nominal gross power of approximately 68 megawatts for Project Permian while evaluating additional units.
As of June 30, 2026, Net Power held $310 million in cash, cash equivalents, and investments and believes existing liquidity will be sufficient to fund obligations for the 12 months following its second-quarter 2026 Form 10-Q filing, assuming it does not enter into additional pre-FID equipment commitments under evaluation. As of the date of the release, no project-level financing, customer deposits, or partner capital for Project Permian had been committed.
