Shares of Eos Energy Enterprises Inc. (EOSE) are plunging 13.51% in pre-market trading on Thursday, following the release of the company's disappointing second-quarter 2025 financial results. The sharp decline comes as the energy storage company reported earnings that fell significantly short of market expectations, despite posting record quarterly revenue.

Eos Energy announced Q2 revenue of $15.236 million, which, although representing a substantial increase from the same period last year, fell well below the analyst consensus estimate of $24.1 million. This 36.83% revenue miss, coupled with substantial losses, has clearly unsettled investors. The company reported a staggering net loss of $222.937 million for the quarter, with operating losses amounting to $63.847 million.

Despite the negative market reaction, Eos Energy Enterprises attempted to highlight positive aspects of its performance. The company emphasized that its quarterly revenue was nearly equivalent to its full-year 2024 results, showcasing considerable year-over-year growth. Additionally, Eos reaffirmed its 2025 revenue outlook of $150 million to $190 million, suggesting confidence in its long-term prospects. However, the market's focus on the missed revenue target and continued losses has overshadowed these positive aspects, leading to the sharp decline in share price during pre-market trading. As the market opens, all eyes will be on how Eos Energy Enterprises plans to address its financial challenges and improve its performance in the coming quarters.
