Most Popular Narrative: 34.1% Undervalued

The prevailing narrative puts Amprius Technologies’ fair value well above the last close, suggesting a substantial gap between market price and perceived fundamentals. This is fueling both excitement and debate as investors eye the story behind the current valuation.

The industry's increasing need for lightweight, high-energy-density battery solutions (for drones, electric aviation, and next-gen vehicles) enables Amprius to maintain premium pricing and outperform on gross and net margins due to its demonstrated product performance advantages, evidenced by record energy density and recent customer wins (for example, AALTO/Airbus and U.S. Army). Diversification of the customer and geographic revenue base through global contract manufacturing partnerships (notably new capacity in South Korea) is expected to reduce revenue volatility and support scale-up, which should improve operating leverage and expand net earnings over time.

Another View: Price-to-Sales Comparison Raises Caution

Taking a different approach, looking at Amprius through its price-to-sales ratio presents a more expensive picture. The company trades at 25.3 times sales, much higher than the US Electrical industry’s 1.9 times and just above the peer average of 24.9 times. Compared to the fair ratio of 2.7 times, this gap signals significant valuation risk if the market cools or expectations reset. Does the stock’s premium already price in all the future growth?
