Eos Energy Enterprises said preliminary second-quarter 2026 revenue will land between $68 million and $69 million, the highest quarterly total in the company’s history. That would mark a sharp step up from the prior-year period, with shipments more than tripling versus the same quarter last year. It also said first-half 2026 revenue already exceeded all of 2025.
Backlog reached about $807 million at June 30, 2026, a company record and roughly 25% higher than the prior quarter. The company said new orders booked in the quarter outpaced shipments recognized, helping lift backlog even as revenue hit a new high.
Cash and restricted cash totaled about $364 million at quarter-end. During the quarter, Eos collected about $78 million from customers, more than the quarter’s revenue.
Gross margin loss is expected to come in between 69% and 73%. The company said the quarter included its move to operating two commercial production lines across two manufacturing facilities, with Battery Line 2 beginning commercial production in mid-June.
Eos said Battery Line 2 has already shown higher yields and faster cycle time than Battery Line 1 in its early ramp. It also completed site acceptance testing for 50% of its bipolar automation line, with full commissioning of all bipolar machines expected in July 2026.
The company said it is advancing toward a 4 GWh annual run-rate capacity by year-end. Following these announcements, the company's shares moved 2.68%, and are now trading at a price of $4.405. If you want to know more, read the company's complete 8-K report here.
