Amprius Technologies reported a Q3 2025 revenue of $21.43 million, a 172.8% year‑over‑year increase from $7.86 million in the same quarter of 2024, and a 42% sequential rise from $15.1 million in Q2 2025. The company’s earnings per share were –$0.03, beating the consensus estimate of –$0.06 by $0.03, a 50% improvement over the prior‑year loss of –$0.10.
The revenue jump was driven almost entirely by the aviation segment, which accounted for 75% of total sales. Demand for unmanned aerial systems (UAS) and other high‑performance applications surged, with record shipments to 159 end customers, including 80 new ones, and a $35 million purchase order from a leading UAS manufacturer. The strong mix of silicon‑anode products, particularly the Sycor line, helped lift the gross profit margin to 15% from 9% in Q2 2025.
Gross margin expansion was matched by a narrowing net loss, which fell to $3.89 million from $10.85 million in Q3 2024, a 64.1% reduction. The improvement reflects both higher‑margin product mix and better operational leverage as volumes increase, offsetting the company’s ongoing investment in manufacturing capacity and R&D. Cash remains robust at $73.2 million with no debt, but the firm is still pursuing cash‑flow break‑even.
Management guided for Q4 revenue of $23.45 million and a full‑year 2025 revenue of $66.88 million, up from the prior guidance of $66.0 million. CEO Kang Sun highlighted the company’s leadership in silicon‑anode technology, noting the launch of 450 Wh/kg commercial batteries, while CFO Ricardo Rodriguez emphasized the 15% gross margin and the 42% sequential revenue growth. President Thomas Stepien underscored the expanded partnerships and the new SiCore cells optimized for UAS, signaling confidence in sustained demand.
Investors reacted cautiously, citing the continued net loss and the need for additional funding to support the planned Colorado facility. Despite the earnings beat, market sentiment remained tempered by concerns over profitability and future capital requirements.
Overall, Amprius’s Q3 results demonstrate a strong revenue engine and improving margins, but the company’s path to profitability remains challenged by ongoing investments and funding needs. The guidance signals confidence in demand, yet the market’s focus on net loss and cash‑flow break‑even highlights the need for continued cost discipline and capital efficiency.
