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%. Operating loss narrowed to $4.3 million and net loss to $3.2 million, versus $6.4 million in the prior-year quarter.
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. Cash and cash equivalents were $74.5 million at June 30, 2026, but operating activities used $40.1 million of cash, including a $20.0 million payment to terminate the Brighton, Colorado factory lease as the company pivots to contract manufacturing with access to over 2.0 GWh of external SiCore capacity and expands its Fremont pilot line. 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.
Amprius Technologies reported strong Q1 2026 revenue growth but continued losses and heavy cash use. Revenue rose to $28.5 million from $11.3 million, driven by higher SiCore battery sales and new customers, lifting gross margin to 20% from a negative margin a year earlier. Operating expenses increased as the company expanded R&D and administrative functions, and Amprius posted a net loss of $5.0 million, improved from a $9.4 million loss.
Cash and cash equivalents were $62.4 million as of March 31, 2026, but operating cash outflow was $37.3 million, largely due to a $20.0 million payment to terminate the Brighton, Colorado plant lease. The company now relies on a global contract manufacturing network and is expanding its Fremont pilot line, supported by an $18.1 million U.S. Defense Innovation Unit contract and related government grant income. Revenue remains concentrated, including sizable shipments into EMEA and Ukraine, and the business continues to face global macro, defense and trade risks.
