Amprius (AMPX) Soars 10.26% on $35M Order, Defense Partnerships Drive Momentum

Amprius Technologies (AMPX) surged 10.26% on Wednesday, extending its three-day winning streak with a cumulative gain of 22.46%. The stock reached an intraday high of $13.55, its highest since October 2025, amid renewed investor enthusiasm for its silicon anode battery technology. The rally follows a $35 million purchase order for SiCore® cells from a top unmanned aerial systems manufacturer, a significant upgrade from a $15 million order earlier this year.

Strategic partnerships are fueling momentum, particularly the collaboration with Nordic Wing to integrate Amprius’ cells into ASTERO ISR drones. This partnership is expected to boost UAV endurance by 90%, positioning the company as a leader in high-energy-density solutions for defense and commercial applications. Additional contracts with BAE Systems and AeroVironment further validate the versatility of Amprius’ technology in critical defense systems, including the Switchblade 300 Block 20 loitering missile.

Financial progress underscores the company’s growth trajectory. Amprius reported $15.06 million in Q2 2025 revenue, reflecting a 150% three-year growth rate. While the firm remains unprofitable with a 150% net loss, a strong current ratio of 6 and a $5.77 million cash flow increase highlight operational stability. The company has also secured 1.8 GWh of contract manufacturing capacity, a key step toward scaling production to meet rising demand.

Analyst sentiment remains supportive, with a consensus fair value of $13—$0.51 above the current price—backed by Amprius’ leadership in 500 Wh/kg energy density technology. However, the stock’s elevated price-to-sales ratio of 34.8x, compared to the industry average of 2.2x, reflects risks tied to narrow market concentration and production scalability. Institutional exposure has grown following its inclusion in the Russell 3000® Index in June 2025, potentially attracting further capital inflow.

Upcoming events, including the CUAV Expo and the H.C. Wainwright Global Investment Conference, will provide additional visibility for Amprius’ innovations. The company’s strategic hiring of automotive expert Mary Gustanski and formation of an Industry Advisory Council signal efforts to diversify its customer base and strengthen operational expertise. Despite challenges in balancing R&D investment with profitability, Amprius’ focus on high-performance battery delivery positions it to capitalize on expanding demand in drones, electric vehicles, and renewable energy storage sectors.
