Third-quarter sales reached a record $39.1 million, up 83% from a year earlier, as U.S. revenue more than doubled from the prior quarter.

Amprius Technologies (AMPX), a silicon-anode lithium-ion battery maker, reported third-quarter revenue of $39.1 million, up 83% from $21.4 million a year earlier, and raised its 2026 revenue outlook to $145 million from at least $140 million.

The Fremont, California company said U.S. revenues increased 2.3 times quarter over quarter to $12.2 million. Sequential revenue growth slowed to 15% from 19% in the second quarter.

GAAP gross margin held at 27%, matching the second quarter. Gross profit was $10.5 million, up $7.2 million and 217% from $3.3 million in the third quarter of 2025.

Net loss attributable to common stockholders was $3.5 million, a $0.4 million improvement from $3.9 million a year earlier, or $0.02 a share versus $0.03. Non-GAAP Adjusted EBITDA was a loss of $1.0 million, compared with $0.2 million of profit in the third quarter of 2025.

Chief Executive Tom Stepien said the results reflected technology leadership and the ability to convert growing customer demand into financial performance, citing deeper relationships across drone, aviation, defense and advanced mobility markets. He said the company introduced SiCore 500, a new battery model, and was selected for a competitive contract to increase U.S. production in 2028.

Amprius said it secured a $75 million U.S. Department of War competitive contract to produce cells in the United States, $22.3 million of which is obligated, by supporting conversion of an existing battery production line with planned output of up to 12 million NDAA-compliant cells annually in 2028. It also introduced SiCore 500, a second-generation silicon anode cell delivering 500 Wh/kg on conventional lithium-ion manufacturing equipment.

Other commercial items included an expanded relationship with Quantum Systems on Vector and Twister ISR platforms, supply of SiCore cells to a U.S. aerospace company producing a solar-powered stratospheric platform, and a design win with a global maritime and defense technology company for an autonomous deep-sea underwater vehicle.

CFO Ricardo C. Rodriguez said the third quarter proved the scalability of the company’s fabless technology and process-owning strategy, and that agreements to establish additional NDAA-compliant production extend that model. CEO Tom Stepien said Amprius enters the fourth quarter with an expanding pipeline and increased manufacturing scale.

For the full year 2026, Amprius now expects revenue of $145 million, gross margin of at least 28%, net loss of less than $10 million including the second-quarter $1.9 million non-cash fair-value charge from the warrant exchange, net loss per share under $0.07, Adjusted EBITDA of at least $2.5 million, and capital expenditure under $10 million. The Adjusted EBITDA target was lowered from at least $4 million. The third-quarter outlook kept the less-than-$10.0-million net-loss target set in the second-quarter update.

The outlook assumes depreciation and amortization of $3.0 million, stock-based compensation of $9.5 million, $1.2 million of Colorado facility expenses, interest income of $1.7 million, government grant income of $8.0 million, and weighted-average shares of 143.4 million. The company said it may recognize additional charges, realize gains or losses, incur financing costs or interest expense, or experience other events in 2026, including those related to capacity expansion, supply-chain disruptions or further cost inflation.

Cash and cash equivalents were $60.7 million at September 30, 2026, down from $90.5 million at year-end 2025. Accounts receivable were $45.9 million and inventories $15.9 million. Stockholders’ equity was $124.7 million.
