Recent Form 8-K reports disclose operating results and preliminary financial information, manufacturing and capacity updates, amendments to a U.S. Department of Energy loan guarantee agreement, senior convertible notes, and other capital-structure matters tied to the company’s funding plan.

Eos Energy Enterprises reported preliminary second-quarter 2026 results. It expects revenue of $68 million to $69 million, the highest quarterly revenue in its history, driven by more than a three-fold increase in shipments versus the prior-year period. Revenue recognized in the first half of 2026 has already surpassed total revenue for 2025.
As of June 30, 2026, Eos anticipates a record backlog of approximately $807 million, about 25% higher than the prior quarter, with new orders exceeding shipments. The company projects a gross margin loss between 69% and 73%, reflecting start-up costs and lower initial volumes during its manufacturing ramp, including the launch of Battery Line 2 and progress toward a targeted 4 GWh annual run-rate capacity by year-end.
Total cash, including restricted cash, is expected to be approximately $364 million, with about $78 million of customer collections in the quarter, exceeding revenue. These figures are preliminary, unaudited management estimates and may differ materially from final results. Full second-quarter results are scheduled for August 5, 2026, followed by an earnings call and shareholder Q&A.
