Why Is AMPRIUS TECHNOLOGIES (AMPX) Stock Moving Today?

Amprius Technologies (AMPX) shares fell 6.76% to $8.55 following the release of third-quarter 2026 financial results. The primary driver for the decline was a wider-than-expected loss, despite the company reporting record revenue and raising its full-year guidance.

What Happened

The company reported third-quarter revenue of $39.1 million, which represented an 83% year-over-year increase. While this figure set a new record for the firm, it missed analyst estimates. The GAAP earnings per share loss was $0.02, a result that narrowly beat consensus expectations. However, the overall bottom-line performance disappointed the market, leading to a significant price adjustment.

Management raised its 2026 revenue guidance to $145 million, up from a previous estimate of $140.64 million. The company also outlined plans to reach 12 million annual U.S. pouch-cell capacity by early 2028. On the earnings call, executives noted that freight costs weighed on margins during the period. Additionally, Applied Energetics nominated Amprius CFO Ricardo C. Rodriguez for a board election.

What The Data Shows

Fundamental data indicates the company has a market capitalization of $1.4 billion and remains unprofitable with a trailing twelve-month EPS of -$0.28. Revenue growth over the same period was 143.6%, while the net margin stood at -33.4%. The stock carries a beta of 2.38 and trades within a 52-week range of $7.02 to $24.23.

Recent trading activity shows the stock moved 6.8% higher over the last eight sessions prior to this drop. In the last 90 days, there were no insider buys and three sells totaling $1.3 million. The most recent insider sales occurred on August 21, 2026, involving CEO Thomas M. Stepien, CTO Stefan Constantin Ionel, and Director Sun Kang. On November 11, 2026, the stock printed two fresh 52-week highs and twelve fresh 52-week lows.

What To Watch

Investors will monitor the company's progress toward its raised 2026 revenue target of $145 million. The market will also watch for further updates on the company's capacity expansion plans and margin management as it works to reduce its net loss.
