Eos Energy Enterprises unveiled its fourth quarter 2025 financial results on February 26, delivering performance metrics that fell substantially short of analyst projections.
The battery storage manufacturer posted a Non-GAAP loss per share of $0.72 for the final quarter. Market analysts had anticipated a smaller loss of $0.18, resulting in a miss of $0.54 per share.
Quarterly revenue totaled $57.99 million. While significant, this figure paled in comparison to Wall Street’s expectation of $92.82 million — representing an approximate shortfall of $35.7 million.
Eos Energy Enterprises, Inc., EOSE
However, there’s an important context to consider: that $58M in quarterly sales marks a remarkable 699.9% surge compared to the year-ago period. The growth trajectory is undeniable, yet it’s failing to keep pace with Wall Street’s aggressive expectations.
The adjusted EBITDA deficit expanded to $71.5 million from $44.6 million in the comparable quarter of 2024. This represents deterioration in operational profitability metrics.
On a more encouraging note, the company closed out 2025 holding $624.6 million in aggregate cash reserves, providing a cushion for near-term operations.
Eos’s order backlog climbed to $701.5 million, representing 2.8 GWh of energy storage capacity. This marks a sequential increase of 9%.
The firm’s commercial opportunity pipeline expanded by 4% to reach $23.6 billion, which leadership highlighted as validation of sustained marketplace interest in its proprietary zinc-based battery technology.
2026 Guidance Falls Short
Looking ahead to fiscal 2026, Eos projected annual revenue ranging from $300 million to $400 million. Wall Street analysts had modeled revenue of $471.26 million. This substantial variance triggered immediate market reaction.
EOSE shares declined 3.05% on the earnings announcement date. The stock has retreated 26.05% during the previous three-month period, although it maintains a 173.46% gain over the trailing twelve months.
Financial Health Raises Flags
Operating margin currently registers at -351.01%. Net margin stands at -1,760.72%. These figures underscore a business still burning cash heavily while scaling production capabilities.
The company’s Altman Z-Score of -19.96 positions it squarely within financial distress parameters. This metric suggests elevated bankruptcy risk probability over the next 24 months.
Insider transaction patterns add another cautionary signal. Five insider selling events occurred during the past three months, accompanied by just one upward EPS revision versus two downward adjustments in the same timeframe.
The stock currently trades at a P/S ratio of 47.85, substantially elevated relative to the company’s historical valuation ranges. Wall Street analysts maintain a consensus price target of $16.13, compared to the current price of $11.13.
InvestingPro assigns Eos Energy a “weak performance” rating for overall financial health.
The Relative Strength Index presently reads 41.26, positioning the stock near oversold levels. Institutional investors hold 48.55% of outstanding shares, while company insiders own a modest 1.33%.
The firm’s current ratio of 1.83 indicates adequate short-term liquidity coverage, though the debt-to-equity ratio of -0.19 raises questions about capital structure sustainability.
Eos Energy finished trading at $11.13 per share on February 26, 2026.
