Eos Energy's Q4 revenue soars 700% but misses Yahoo Finance forecasts
Eos Energy Enterprises (EOSE) released its Q4 2025 financial results on February 26, 2026, revealing a sharp rise in revenue but falling short of market expectations. The company's quarterly earnings showed a 699.9% year-over-year revenue increase to $57.99 million, yet this figure remained $35.7 million below yahoo finance forecasts. Investors reacted cautiously, with shares dipping 3.05% on the day of the announcement.
The company's full-year revenue for 2025 climbed to $114.2 million, supported by strong demand for its zinc-based battery systems. Its commercial pipeline expanded by 4% to $23.6 billion, while the order backlog grew 9% sequentially to $701.5 million—equivalent to 2.8 GWh of storage capacity. Despite this growth, financial pressures persisted, with an adjusted EBITDA loss widening to -$71.5 million from -$44.6 million in the previous year.
Eos Energy reported a Non-GAAP EPS loss of -$0.72 for Q4, missing estimates by $0.54. The company's operating margin stood at -351.01%, and its net margin at -1,760.72%, highlighting ongoing heavy investment. Cash reserves at year-end totalled $624.6 million, but financial stress indicators remained high, with an Altman Z-Score of -19.96, suggesting elevated risk over the next two years.
Looking ahead, Eos guided 2026 revenue to between $300 million and $400 million—well below the $471.26 million yahoo finance consensus. The company's market capitalisation has fluctuated in recent months, dropping from $4.1 billion in October 2025 to around $3.6 billion by late February 2026. This decline followed the earnings release and share sales by a major stakeholder.
Over the past three months, Eos Energy's stock has fallen by 26.05%, reflecting investor concerns about profitability and future growth.
Eos Energy's latest results show rapid revenue growth alongside widening losses and a cautious 2026 outlook. The company's strong order backlog and expanding pipeline suggest continued market interest in its battery solutions. However, financial metrics such as negative margins and a low Altman Z-Score point to ongoing challenges as it scales operations.
