NET Power (NPWR) Surges 23.65% as Institutional Buyers Fuel Rally Despite Earnings Miss

Shares of NET Power (NPWR) surged to a 2025 high on October 8, with an intraday rally of 39.03% amid growing institutional interest. The stock closed up 23.65%, driven by strategic capital inflows from major investors who increased their stakes in the clean energy technology firm. This sharp reversal contrasts with the company’s recent quarterly earnings miss, highlighting market confidence in its long-term decarbonization-focused business model.

Institutional ownership now accounts for 53.62% of the company’s float, with JPMorgan Chase & Co. and Deutsche Bank AG significantly expanding their holdings. JPMorgan’s second-quarter position grew by 48.7%, while Deutsche Bank’s first-quarter stake rose 63.0%. These moves signal a shift in sentiment toward undervaluation and potential in the company’s proprietary Net Power Cycle technology, despite a projected $0.40-per-share loss for the fiscal year.

The company’s market capitalization of $564.06 million and a beta of 0.71—reflecting lower volatility than the broader market—position it as a defensive play within the clean energy sector. While recent operational updates, such as cost reductions for the SN1 project, were disclosed in August, the lack of new developments since then underscores the market’s focus on institutional activity rather than near-term operational catalysts. Analysts remain cautious about profitability challenges but acknowledge the alignment of the firm’s mission with global decarbonization trends.
