Eos Energy shares tumble 3% on 38% Q4 revenue miss
Battery storage company delivered $58M in quarterly sales against $93M consensus estimates despite full-year revenue growth
Eos Energy Enterprises shares fell 3.1% in Thursday trading after the battery storage company reported fourth-quarter revenue that missed analyst expectations by approximately 38%, casting doubt on execution despite impressive year-over-year growth.
The New Jersey-based company reported $58 million in quarterly revenue, falling short of the consensus estimate between $93.36 million and $93.87 million. The shortfall came despite a 90% increase compared to the third quarter and approximately eightfold growth from the prior year.
The stock closed at $11.13, trading below its 50-day moving average of $13.89 but remaining above the 200-day line at $10.19. The decline extends a broader pattern of volatility for Eos shares, which have traded in a 52-week range between $3.07 and $19.86.
Chief Executive Officer Joe Mastrangelo acknowledged the disappointment in the earnings statement. "While disappointed in not meeting revenue expectations, execution improved significantly as 2025 progressed, and we exited the year with clear operational momentum," he said.
For the full year 2025, Eos reported revenue of $114.2 million, representing more than sevenfold growth compared to 2024. The company also secured over $240 million in fourth-quarter bookings with nearly 1.1 gigawatt-hours of new orders across eight customers in U.S. and international markets.
The order backlog stands at $701.5 million representing 2.8 gigawatt-hours, up 9% sequentially, while the commercial opportunity pipeline increased 64% year-over-year to $23.6 billion. Additionally, Eos ended the year with a record cash balance of $624.6 million following a $600 million convertible notes issuance, and stated that "substantial doubt no longer exists" about its ability to continue as a going concern.
Looking ahead, the company initiated 2026 revenue guidance of $300 million to $400 million, representing 2.6 to 3.5 times growth from 2025 levels. Mastrangelo said the focus would shift to "disciplined scale and margin improvement — driving manufacturing efficiency, improving unit economics quarter-over-quarter, and converting our backlog into high-quality revenue."
Analyst sentiment remains mixed. According to MarketBeat data, Eos holds a consensus "Hold" rating from nine analysts, with two recommending "Buy," six suggesting "Hold," and one at "Sell." The average price target stands at $13.50, implying potential upside of 21% from Thursday's close, with forecasts ranging from $6 to $22.
Public Investing shows a more bullish "Buy" consensus from five analysts, with 40% rating the stock a "Strong Buy." The median price target across different sources hovers around $15.00.
The revenue miss underscores execution challenges at a critical inflection point for the energy storage company. While Eos has demonstrated substantial revenue growth and secured significant orders, the fourth-quarter shortfall raises questions about its ability to consistently convert its backlog into recognized revenue as it scales production capacity to 2 gigawatt-hours annually.
The battery storage sector has attracted increased investor attention as utilities seek solutions for renewable energy integration, but companies face pressure to demonstrate both growth and profitability as the industry matures. Eos's negative earnings per share of $8.31 over the trailing twelve months highlights the challenges still ahead.
