ATLANTA, GA – – (Globe Newswire – April 21, 2025) – – A shareholder class action lawsuit has been filed against NET Power Inc. (“Net Power” or “the Company”) (NYSE: NPWR). The lawsuit alleges that Defendants made materially false and/or misleading statements and/or failed to disclose material adverse facts regarding Net Power’s business, operations, and prospects, including allegations that: (i) Net Power was unlikely to complete Project Permian on schedule, and the project was likely to be significantly more expensive than Defendants had represented, because of, inter alia, supply chain issues and numerous site- and region-specific challenges; (ii) accordingly, Defendants’ projections regarding the time and capital needed to complete Project Permian were unrealistic; and (iii) the increased time and capital needed to complete Project Permian were likely to have a significant negative impact on the Company’s business and financial results.
