With the stock up sharply over the past year, trading at US$17.83 and sitting at a discount to both analyst targets and some intrinsic value estimates, the key question is whether there is still a buying opportunity here or if the market is already pricing in future growth.

Most Popular Narrative: 7.4% Undervalued

On the most followed narrative, Amprius Technologies' fair value of $19.25 sits above the last close at $17.83. This puts the focus squarely on whether the growth story supports that gap.

Analysts have lifted their price target on Amprius Technologies by about $1.70 to $19.25, citing stronger than expected Q4 results, improving profitability, and growing demand for its silicon anode battery technology across drones, satellites, light EVs, robotics, and eVTOL markets.

Want to see what underpins that fair value uplift? The narrative leans heavily on rapid revenue expansion, rising margins, and a future earnings multiple that assumes meaningful scale and commercialization across several end markets.

Result: Fair Value of $19.25 (UNDERVALUED)

However, this hinges on Amprius scaling production efficiently and keeping its aviation heavy revenue base intact. Contract delays or demand shifts could quickly challenge the story.

Another Angle on Valuation

The first view leans on fair value estimates and analyst targets that suggest upside, but the current P/S of 28x tells a different story. It sits well above the US Electrical industry at 2.6x, peers at 19.2x, and even the 6.9x fair ratio, which points to meaningful valuation risk if sentiment cools.

Put simply, the stock is priced for strong execution. Anyone following it closely may want to ask how much disappointment the current multiple can absorb before expectations reset.
