Why Amprius Technologies Stock Is Back in Focus

Amprius Technologies (AMPX) is drawing attention after announcing a collaboration to supply silicon anode lithium-ion batteries for Matternet’s M2 delivery drones, while also facing short seller allegations about its reported orders and disclosures.

Recent volatility has been sharp, with the share price falling 4.62% in the last session, 17.17% over the week and 12.73% over 90 days. At the same time, the year-to-date share price return is 86.61% and the 1-year total shareholder return is very large. This suggests that earlier momentum is now cooling as the Matternet deal and short seller claims recalibrate expectations and perceived risk.

So with Amprius sitting on strong year to date gains, alongside a recent pullback and analysts’ targets above the current US$16.31 share price, is this a genuine mispricing or is the market already banking on future growth?

Most Popular Narrative: 15.3% Undervalued

The most followed narrative currently places Amprius Technologies' fair value at $19.25 per share, above the recent $16.31 close, framing the stock as undervalued against its cash flow potential using a 9.26% discount rate.

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 (e.g., AALTO/Airbus and U.S. Army).

Want to see what kind of revenue climb and margin shift is included in that fair value tag? The narrative focuses on sharp growth, rising profitability, and a rich future earnings multiple. Curious which assumptions carry the model and how they build up to $19.25?

Result: Fair Value of $19.25 (UNDERVALUED)

However, there are still key pressure points to watch, including Amprius' reliance on aviation and drone customers, as well as the execution risk in scaling its silicon anode manufacturing.

Another View: Expensive on Sales

The DCF work suggests Amprius looks undervalued, yet the P/S ratio of 26.1x is far higher than the US Electrical industry at 2.5x, the peer average at 15.4x, and the fair ratio of 6.8x. That gap points to real valuation risk if sentiment cools.

Before leaning too heavily on headline multiples, it is worth seeing how the numbers line up in detail, then judging whether that premium feels justified for you or stretched enough to introduce downside risk on any disappointment.
