Most Popular Narrative: 13.9% Undervalued

With a narrative fair value of $14.67 versus the last closing price of $12.63, the latest narrative points to notable upside, driven by powerful business shifts and investor optimism.

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. This should improve operating leverage and expand net earnings over time. Ongoing investment in automation and manufacturing capacity, supported by government contracts like the $10.5M Defense Innovation Unit award, positions Amprius to capture a larger share of future high-margin opportunities in defense and critical infrastructure, enhancing both revenue visibility and earnings stability.
