Amprius Technologies, Inc. (AMPX)

Amprius Technologies, Inc. (AMPX) is a leader in next-generation lithium-ion battery technology, headquartered in Fremont, California. Led by CEO Dr. Kang Sun, Amprius’s strategic mission is to "power the future of electric mobility through the highest-energy density batteries in the world." The company holds a unique industry position as the pioneer of the silicon nanowire anode, a technology that allows for significantly higher energy density and faster charging compared to traditional graphite anodes. Amprius’s vision is to enable the electrification of markets where weight and energy density are critical, such as high-altitude pseudo-satellites (HAPS), unmanned aerial vehicles (UAVs), and the broader aviation sector. By late 2025, AMPX stock has become a "Deep-Tech Standout," following a 173% year-over-year revenue increase and a massive expansion of its global contract manufacturing network.

The business operations of Amprius are focused on scaling its "Silicon Anode Platform" for commercial use. The company’s core business is currently driven by the aviation segment, which accounted for 75% of its total revenue in late 2025. In fiscal 2025, Amprius reported third-quarter revenue of $21.4 million, a 42% sequential increase, as it converted pilot programs into formal deployments. The 2026 strategic roadmap focuses on the "Korea Battery Alliance," a consortium of Korean contract manufacturers that has increased Amprius’s global capacity to over 2 GWh. This "Asset-Light Scaling Model" allows Amprius to meet surging demand for its 450 Wh/kg and 500 Wh/kg batteries without the massive capital expenditure of building its own gigafactories. Amprius holds a "Technological Moat" backed by an extensive patent portfolio that covers the design and fabrication of silicon nanowire structures. Future growth is projected through "Defense and Critical Infrastructure" contracts, as the company provides high-performance power for mission-critical applications. By maintaining a 15% gross margin and improving operational efficiency, Amprius is bridging the gap from a research lab to a high-volume manufacturing powerhouse.

The AMPX stock is listed on the New York Stock Exchange (NYSE) under the ticker symbol AMPX. For investors monitoring the AMPX stock price, the company represents a "High-Growth Battery Play" with a focus on premium, high-density applications. The Amprius Technologies Inc stock has attracted significant attention in 2025 for its ability to beat revenue projections and secure major international manufacturing partnerships. The AMPX stock price is highly sensitive to "Customer Qualification Milestones" and "Energy Density Breakthroughs." Analysts tracking the AMPX stock emphasize the company’s "Leading-Edge Advantage," noting that its batteries offer nearly double the energy density of standard Tesla cells. Investors interested in the AMPX stock price frequently look at "Backlog Conversion" and the progress of the "Korea Alliance" as key performance indicators. As the aviation and defense sectors accelerate their transition to electric power, the AMPX stock price reflects the company’s role as the provider of the "High-Octane" fuel of the battery world.
