We came across a
bullish thesis on Amprius Technologies, Inc. on Value investing subreddit by BestNameTotally. In this article, we will summarize the bulls’ thesis on AMPX. Amprius Technologies, Inc.'s share was trading at $10.61 as of December 1st.
Amprius Technologies, Inc. (AMPX) is emerging as a leader in high-performance silicon-anode batteries, a technology that is already commercially shipping in consumer electronics and represents a significant evolution of lithium-ion chemistry. Unlike solid-state, silicon anodes provide a near-term solution for higher energy density, faster charging, and lighter weight, and adoption is accelerating across smartphones, wearables, EVs, drones, and aerospace applications. The market for silicon-anode batteries, valued at $357 million in 2024, is projected to reach $3.6 billion by 2030, implying a 50% CAGR, driven by premium applications that justify higher pricing.
AMPX has been in commercial production since 2021, offering batteries with 100% active silicon anodes, achieving 450–500 Wh/kg energy density and 1,300 Wh/L volumetric energy density, which is industry-leading with no comparable competition. The company reported Q3 2025 revenue of $21.4 million, up 173% YoY and 42% QoQ, surpassing estimates, while gross margins turned positive at 15% for the second consecutive quarter.
Revenue for the first nine months of 2025 reached $47.9 million versus $24 million for all of 2024, and the company ended Q3 with $73.2 million in cash and zero debt. Key partnerships include aerospace players and KULR, targeting drones, EVs, and aerospace, markets that pay a premium for performance and energy density.
AMPX’s stock, trading around $11–12, has seen a 995% increase over the past year. While valuation is high, the company’s accelerating revenue growth, margin improvement, expanding addressable market, and potential participation in Amazon’s Device Climate Tech Accelerator position it as a high-growth technology play with multiple catalysts. Scaling execution and competitive pressures remain risks, but the proven technology, commercial traction, and large market opportunity create a compelling investment narrative with significant upside potential.
Previously we covered a
bullish thesis on Enovix Corporation (ENVX) by jamesfreakinbond84 in February 2025, which highlighted its 3D battery architecture, strong IP portfolio, and path toward large-scale commercialization. The company's stock price has depreciated approximately by 36.49% since our coverage. The thesis still stands as ENVX advances commercialization. BestNameTotally shares a similar perspective but emphasizes AMPX’s proven silicon-anode technology.
