Opening Summary
Amprius Technologies, Inc. (AMPX), a Fremont, California-based maker of silicon-anode lithium-ion batteries serving the drone, aviation, defense, and advanced mobility markets, saw its shares fall 5.89% on Wednesday. The stock traded around $8.63, down from a prior-session close of $9.17. The decline followed the company's third-quarter 2026 earnings report, released after Tuesday's close, which showed a bottom-line miss that outweighed a strong top-line beat and sent shares sharply lower in extended trading.
Earnings Results: A Bottom-Line Miss
The market reaction was an earnings-driven move. Amprius posted third-quarter revenue of $39.1 million, up 83% year over year and ahead of the roughly $35.9 million analysts had modeled. Gross profit climbed 217% to $10.5 million, and gross margin expanded to 27% from 15% a year earlier. Despite that momentum, the company reported a GAAP net loss of $0.02 per share, wider than the consensus estimate of a $0.01 loss. Net loss attributable to common stockholders was $3.5 million.
Investors focused on the expense side of the equation. Operating expenses rose about 90% year over year, outpacing revenue growth, while adjusted EBITDA swung to roughly negative $1.0 million from a modest positive a year earlier as research and development spending more than doubled. The widening loss and negative EBITDA print overshadowed the record sales figure, driving the shares lower.
Guidance and Business Highlights: Mixed Signals
Management raised its full-year 2026 revenue outlook to $145 million, up from a prior target of at least $140 million, and guided to gross margin of at least 28%, a net loss below $10 million, and adjusted EBITDA of at least $2.5 million. However, the implied fourth-quarter margin step-up and sharp EBITDA swing left little room for execution missteps, tempering the upbeat top-line commentary.
Amprius also highlighted a $75 million U.S. Department of War contract for domestic cell production, with $22.3 million obligated, and introduced its SiCore 500 second-generation cell at 500 Wh/kg energy density. While these announcements underscore a growing defense and aviation pipeline, they were not enough to offset the near-term profitability concerns driving the selloff.
Market Context and Trading Activity
The decline was driven by company-specific news rather than broad market weakness. Amprius' move reflected a continued reaction to earnings rather than a sector-wide rotation, as the stock extended losses that began in after-hours trading following the report. Trading activity remained elevated as investors repriced shares against the wider-than-expected loss, and the stock's slide pushed it back below levels reached in the prior session's rally toward $9.50.
What Comes Next for AMPX
Looking ahead, investors will track whether AMPX can deliver the fourth-quarter gross margin and adjusted EBITDA improvements implied by its updated guidance. Key areas of focus include the ramp of U.S. production capacity, progress on the Department of War contract, and continued execution across drone, aviation, and defense customers. Risks include the company's reliance on contract manufacturing partners, supply-chain and tariff exposure, and the need to convert a growing backlog into sustained profitability.
