Eos Energy Enterprises shares fell 12.18% to $3.82 on strong revenue growth that somehow failed to impress the market. The zinc-storage battery maker reported second-quarter sales of $68.8 million, up 351% from last year, yet posted a $275.7 million net loss. Investors punished the stock anyway, sending it lower in after-hours trading.
The disconnect between growth and losses tells the real story. Eos delivered 207% more battery units, pushing first-half revenue past its entire 2025 total. But the company burned through a $48.8 million gross loss with a negative 71% margin. Factory capacity remained underused despite the production surge, and project expenses kept climbing. Adjusted EBITDA losses hit $71.4 million compared to $51.6 million a year earlier.
What actually caught the market's attention was the $807 million backlog Eos built by quarter-end, covering 3.4 GWh of projects. Four brand new customers placed orders alongside two returning clients. After the quarter closed, Frontier Power USA locked in a $100 million order for the Blanquilla project's first phase, part of a much larger 2 GWh reservation deal. The joint venture raised $263 million in funding and has over $1 billion in deployable capital lined up.
Eos narrowed its 2026 revenue guidance despite ramping production at its Thorn Hill plant. The company faces a classic growth trap, where scaling operations burns cash faster than sales can offset it. The backlog growth and major customer wins suggest demand remains real. Whether the company can turn that demand into actual profits is the question that sent shares tumbling.
