Eos Energy Enterprises unveiled its fourth-quarter 2025 financial results on February 26, delivering figures that fell considerably short of Wall Street’s projections.
The battery storage specialist recorded a Non-GAAP loss per share of $0.72 during the quarter. This missed the Street’s anticipated loss of $0.18 by a substantial $0.54.
Quarterly revenue reached $57.99 million. While this might appear significant, it pales against analyst expectations of $92.82 million — representing a miss of approximately $35.7 million.
Eos Energy Enterprises, Inc., EOSE
However, there’s important context: that $58M top-line figure actually represents a remarkable 699.9% surge compared to the year-ago period. The growth trajectory is undeniable. The challenge lies in the pace failing to satisfy market expectations.
The adjusted EBITDA deficit ballooned to $71.5 million from the year-earlier loss of $44.6 million. This marks deterioration rather than improvement.
On a brighter note, Eos concluded 2025 holding $624.6 million in total cash reserves, providing some cushion for future operations.
The firm’s order backlog climbed to $701.5 million, representing 2.8 GWh of energy storage capacity. This reflects a 9% sequential increase.
The commercial opportunity pipeline expanded 4% to reach $23.6 billion, which leadership highlighted as validation of sustained market appetite for its zinc-based battery technology.
Forward Guidance Disappoints Investors
For the complete 2026 fiscal year, Eos projected revenue spanning $300 million to $400 million. Wall Street had been modeling $471.26 million. This meaningful disconnect caught investor attention immediately.
EOSE shares declined 3.05% following the earnings announcement. The stock has retreated 26.05% during the preceding three-month period, although it maintains a 173.46% gain over the trailing twelve months.
Balance Sheet Metrics Signal Caution
The operating margin currently registers at -351.01%. The net margin stands at -1,760.72%. These figures underscore a business still heavily in expansion and investment mode.
The Altman Z-Score reading of -19.96 categorizes Eos squarely within the financial distress classification. This metric suggests elevated probability of financial challenges over the coming two years.
Insider trading patterns compound concerns. The past three months witnessed five insider sale transactions, accompanied by only one upward EPS revision versus two downward adjustments during that timeframe.
The present P/S ratio of 47.85 sits well above the company’s historical trading ranges. The average analyst price target reaches $16.13, compared to the recent closing price of $11.13.
InvestingPro characterizes Eos Energy’s financial condition as demonstrating “weak performance.”
The RSI indicator currently reads 41.26, positioning the stock near oversold levels. Institutional holders control 48.55% of shares outstanding, while company insiders own merely 1.33%.
The firm’s current ratio of 1.83 indicates adequate coverage of near-term liabilities, though the debt-to-equity ratio of -0.19 raises questions about capital structure.
Eos Energy shares settled at $11.13 on February 26, 2026.
