Amprius Technologies, Inc. (AMPX) stock drew increased retail chatter on Friday after the company reported strong third-quarter (Q3) revenue supported by a rise in new customers and larger orders from existing ones.
The firm reported a Q3 revenue of $21.4 million, marking a 42% year-on-year (YoY) surge, and posted a loss per share (EPS) of $0.03. Both revenue and EPS figures came in better than the analysts’ consensus estimates of $17.46 million in revenue and a loss per share of $0.06, respectively, according to Fiscal AI data.
According to the lithium-ion battery producer, the surge in sales was driven by both new customers and increased orders from existing clients. Only one customer accounted for more than 10% of Q3 revenue, reflecting increased diversification.
The backlog stood at $53.3 million, including a $35 million order from a UAS manufacturer, representing an 83% quarter-on-quarter increase. Amprius’ stock traded over 2% higher on Friday, after the morning bell.
