About Amprius Technologies
From its filings with the US Securities and Exchange Commission
Amprius Technologies is based in Fremont, California and is incorporated in Delaware. Its shares trade on NYSE under the ticker AMPX. The SEC classifies its business as miscellaneous electrical machinery, equipment & supplies. In the fiscal year to 31 December 2025, it reported revenue of $73.0m and a net loss of $44.0m. At that date it held total assets of $156.9m and shareholders' equity of $103.8m.
Amprius Technologies, Inc. develops, manufactures and markets lithium-ion batteries for mobility applications, including aviation, ground and marine vehicles. Our disruptive silicon anode technology is intended to enable batteries with high energy density, high power density and fast charging capabilities over a wide range of operating temperatures. This results in our batteries providing superior performance compared to conventional graphite lithium-ion batteries. Our silicon anodes are a direct drop-in replacement of the graphite anode in traditional lithium-ion batteries, and our manufacturing processes leverage the manufacturing processes for conventional lithium-ion batteries and the related supply chain.
Currently, our batteries are primarily used for existing and emerging aviation applications, including unmanned aerial systems or “UAS”, such as drones and high-altitude pseudo satellites or “HAPS”. We believe our proprietary technology has the potential for broad application in electric transportation. Our batteries and their performance specifications have been tested and validated for application by various customers, including AALTO Airbus, AeroVironment, BAE Systems, Kraus Hamdani Aerospace, Nokia Drone Networks, Nordic Wing, Teledyne FLIR and the U.S. Army. Our total customer engagements since inception grew to over 500 customers with shipments to hundreds of customers during the year ended December 31, 2025.
