Eos Energy Enterprises said preliminary second-quarter 2026 revenue is expected to land between $68 million and $69 million, its highest quarterly revenue ever.
That would mark a sharp jump from the prior year period, with shipments more than tripling versus the second quarter of 2025. Revenue recognized in the first half of 2026 also already exceeded the company’s total revenue for all of 2025.
Backlog reached about $807 million at June 30, 2026, a company record and up roughly 25% from the prior quarter. The increase came as new orders booked outpaced shipments during the quarter.
Cash, including restricted cash, was about $364 million at quarter-end. Eos said it received about $78 million of customer collections during the quarter, more than the revenue it recognized.
The company expects a gross margin loss between 69% and 73% for the quarter. It said the second quarter was the first time it operated two commercial production lines across two manufacturing facilities, with Battery Line 2 beginning commercial production in mid-June.
Battery Line 2 has already shown higher yields and faster cycle times than Battery Line 1, according to the company. Eos said it is moving toward a 4 GWh annual run-rate capacity by year-end.
On the manufacturing side, Eos said it completed site acceptance testing for 50% of its bipolar automation line, with full commissioning expected in July 2026. Today the company's shares have moved 8.16% to a price of $4.64. If you want to know more, read the company's complete 8-K report here.
