Amprius delivered a strong second quarter, with revenue jumping 126 percent to $34 million compared to the same period last year. While the company still lost about $5 million, this was a significant improvement from the prior year. More importantly, management raised its full-year revenue forecast to at least $140 million and expects to reach positive adjusted EBITDA, a measure of core operational profit that excludes certain non-cash costs.

This performance supports the view that Amprius is successfully moving from testing its battery technology to selling it at scale. By hitting its revenue targets and narrowing its losses, the company is proving it can manage the high costs of building advanced silicon-anode batteries while finding enough demand in the aerospace and defense sectors to fuel its growth.

Key highlights

• Revenue growth accelerating: Revenue grew 126% to $34.0 million compared to the same period last year, driven by healthy demand for high-capacity batteries in the drone and electric vehicle markets. This more than doubles the $15.1 million the company earned a year ago and shows the business is successfully scaling its production through contract partners.
• Profit margins expanding: Gross margin, which is the percentage of revenue left after paying for the direct costs of making the batteries, rose to 27%. This is a significant jump from 9% a year ago and shows that the company is becoming much more efficient as it produces higher volumes of its silicon anode technology.
• Major new contracts: The company secured a multi-year contract with motorcycle maker Stark Future that could be worth more than $100 million, alongside a new $24.0 million order from a European drone developer. These deals provide a clear path for future growth and show that large industrial customers are committing to Amprius technology for their long-term product lines.
• Fremont facility expansion: The company has started installing about 40% of the required production tools at its pilot manufacturing line in California. This expansion is partially funded by the Defense Innovation Unit, helping the company increase its domestic making capacity without footing the entire bill alone.
• Full year outlook raised: Management raised its 2026 revenue guidance to at least $140 million, up from the previous forecast of $130 million. They also expect profit margins for the full year to be at least 28%, which would be an improvement over the 27% achieved this quarter.

Our take: A very strong quarter that shows this battery technology is moving from the lab to large-scale commercial use. Raising the full-year revenue target to $140 million and hitting 27% margins proves the business can grow fast while making each unit more profitably. This performance strengthens the long-term case for the company.
