Equity & Capital Structure Analyst

Amprius has completed its ATM program, raising about $97.5M in net equity proceeds.

Amprius Technologies completed sales under its at-the-market equity program, which allowed issuance of common stock up to an aggregate offering price of $100.0 million. Through this facility, the company issued 25.5 million shares of common stock and realized aggregate net proceeds of approximately $97.5 million, indicating substantial use of the available capacity.

For the three months ended December 31, 2025, Amprius raised about $19.6 million in net proceeds at an average price of $11.17 per share before concluding the program. The sales agreement automatically terminated after all authorized shares were sold, and the company states it does not intend to make further sales under this agreement, meaning this specific ATM source of equity financing is now closed.
