Eos Energy Sinks Despite Record Revenue Growth and $100M Battery Order

Eos Energy Enterprises (EOSE) reported second-quarter revenue of $68.8 million, up 351% from the same period last year.

A $100 million Blanquilla battery order contributed to Eos' record backlog of $807 million, covering 3.4 GWh of planned projects.

Despite the strong sales growth, the company posted a net loss of $275.7 million due to underused factory capacity and increased project expenses.

Eos narrowed its 2026 revenue guidance to between $300 million and $350 million, down from its previous projection of $300 million to $400 million.
