## Exhibit 99.1

**Net Power Reports First Quarter 2026 Results** 

**and Provides Business Update**

DURHAM, N.C.--(BUSINESS WIRE)—May 11, 2026--Net Power Inc. (NYSE: NPWR) ("Net Power" or the "Company") today announced its financial and operational results for the first quarter ended March 31, 2026.

"We remain excited about the opportunity set in front of us and believe Net Power's in-house engineering capabilities and expertise in power generation and carbon capture utilization can transform natural gas into the lowest-cost form of clean, reliable electricity," said Danny Rice, Chief Executive Officer of Net Power. "As a critical next step to securing a long-term power purchase agreement (PPA) for Project Permian Phase I and subsequent larger scale Net Power deployments, Net Power has engaged a strategic advisor to facilitate our power offtake discussions. Successfully securing a formalized offtake agreement will catalyze our project financing and keep us on track for a final investment decision in the back half of this year—preserving our timeline to become the first operational natural gas power plant with post-combustion carbon capture in the United States."

**Key Business Updates:**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Advanced Permian Basin clean firm power development:** Net Power continued work on schedule for its clean firm power development at its original Project Permian site in West Texas, which will utilize Siemens A35 gas turbines packaged by RPS paired with Entropy's proven post-combustion capture (PCC) technology and target 80MW of electrical output for Phase I. Final investment decision (FID) for the initial deployment is expected in the second half of 2026 with targeted commercial operations by early 2029.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Progressing towards joint development agreement (JDA) with Entropy Inc. ("Entropy"):** Net Power and Entropy continued diligence in anticipation of signing a JDA to deploy natural gas-fired power generation with post-combustion carbon capture (PCC) across the United States. Entropy is a Canada-based leader in PCC technology, with commercially deployed operations at the Glacier Gas Plant in Alberta, Canada. Entropy's technology has demonstrated high energy efficiency and a proven carbon dioxide capture rate of approximately 90 percent.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Maintained strong financial position:** Ended the quarter with approximately $319 million in cash, cash equivalents, and investments.

These factors, risks and uncertainties include, but are not limited to, risks relating to the uncertainty of the projected financial information with respect to the Company and risks related to the Company's ability to meet its projections; the capital-intensive nature of the Company's business model, which will likely require Net Power to raise additional capital in the future; uncertainty regarding the current and future market for abated natural gas-generated power; the ability of the Company to effectively secure licenses for third-party PCC technology and to integrate such technology in its projects; barriers the Company may face in its attempts to deploy and commercialize its technology; the complexity of the machinery the Company relies on for its operations and development, including Entropy's PCC technology; the Company's ability to adequately control or accurately predict the costs associated with its projects; barriers that the Company may face in its attempts to deploy projects; the complexity of the machinery the Company relies on for its operations and development; potential changes and/or delays in site selection and construction that result from regulatory, logistical, and financing challenges; the Company's ability to establish and maintain supply relationships; risks related to strategic investors and partners, including potential conflicts of interests between the Company and such investors and partners; the Company's ability to successfully commercialize its operations; the lack of federal support for clean energy technology by the Trump administration; the availability and cost of technological components and raw materials for its projects; the impact of potential delays in discovering manufacturing and construction issues; the ability of Net Power's commercial plants to efficiently provide net power output; the impact of public perception of fossil fuel-derived energy on the Company's business; any political or other disruptions in gas producing nations; the Company's ability to protect its intellectual property and the intellectual property it licenses; risks relating to data privacy and cybersecurity, including the potential for cyberattacks or security incidents that could disrupt our or our service providers' operations; current and potential litigation that has been and may be instituted against the Company; and; and other risks
