Amprius Technologies (AMPX) The Gateway Conference 2025 summary

Technology and innovation

• Developed silicon nanowire anode technology, originating from Stanford, enabling 100% silicon anode batteries with up to 500 Wh/kg specific energy density and 1,300 Wh/L volumetric energy density.

• Batteries offer high power (10C discharge), fast charging (0–80% in under six minutes), and wide operating temperature range (–30°C to 60°C).

• Two main technology platforms: SiMaxx (Stanford-origin) and SiCore (in-house developed, launched 2024), both supporting industry-leading performance.

• Passed U.S. military safety tests and supported by extensive patent portfolio.

• Real-world applications show significant performance improvements in drones, military, consumer electronics, and electric vehicles.

Manufacturing and business model

• Operates a contract manufacturing model with facilities in China, South Korea, and developing U.S. partnerships, providing nearly 2 GW capacity.

• No in-house volume manufacturing, reducing capital needs and liabilities; leverages external facilities for scalability.

• Recently added a pilot line in Fremont, California, funded by the U.S. Department of Defense, to accelerate prototype delivery.

• Maintains a healthy balance sheet with no debt.

• Protects IP through on-ground management at manufacturing sites.

Market focus and customer engagement

• Focuses on aviation (drones, high-altitude pseudo-satellites, eVTOL, fixed-wing electric aircraft), light electric vehicles, and AI-related applications.

• Over 300 customer engagements globally; 86% of shipments last quarter were outside the U.S.

• Key customers include Airbus, Teledyne FLIR, BAE Systems, and the U.S. military.

• Recent collaboration with Nordic Wing, a leading European drone manufacturer, expected to drive further revenue and engagement.

• Revenue has grown sequentially every quarter since IPO, consistently beating Wall Street consensus.
