1. Fourth-Quarter Financial Results
Eos recorded $58.0 million in fourth-quarter revenue, a 90% quarterly increase and approximately eightfold year-over-year growth. The company secured over $240 million in orders totaling 1.1 GWh from eight customers, driving its order backlog to $701.5 million. Q4 gross loss improved by 230 basis points, while net loss was $120.5 million and adjusted EBITDA loss was $71.5 million.
2. Full-Year 2025 Performance
For full-year 2025, revenue reached $114.2 million, more than seven times the prior year, supported by a 609% increase in customer deliveries. Gross loss narrowed by 408 basis points to $143.8 million, and net loss was $969.6 million, largely reflecting $746.8 million in non-cash fair-value and stock-based charges. Adjusted EBITDA loss improved by 812 basis points to $219.1 million, and the commercial pipeline expanded to $23.6 billion.
3. Operational and Liquidity Highlights
The balance sheet strengthened with a $624.6 million cash position following a $600 million senior convertible notes issuance and registered direct stock offering. Annual production capacity reached 2 GWh through subassembly automation and process optimization, eliminating substantial doubt about the company’s ability to continue as a going concern.
4. 2026 Outlook and Technology Launch
Eos initiated 2026 revenue guidance of $300–400 million and launched the Indensity™ architecture, capable of delivering up to 1 GWh per acre with enhanced flexibility and safety. The next-generation design applies spatial intelligence to optimize site layouts and aims to be cost competitive on an installed $/kWh basis against incumbent storage technologies.
