Amprius Technologies, Inc. delivered rapid growth for the quarter ended June 30, 2026. Revenue rose to $34.0 million from $15.1 million a year earlier, driven mainly by SiCore lithium‑ion battery sales, and gross margin improved to 27% from 9%.

For the first six months of 2026, revenue reached $62.6 million, up from $26.4 million, with net loss improving to $8.2 million.

An $18.1 million Defense Innovation Unit contract supports this expansion, with $1.5 million recognized year‑to‑date. Key risks include dependence on defense-related customers (notably Ukraine), geopolitical and trade uncertainties, potential Chinese export controls on battery materials, and continued operating losses that may require additional capital.
