$EOSEPress releaseOct 19, 2026, 8:30 AM ETRead the release

Eos Energy pre-announced preliminary Q3 2026 revenue of $82-83 million, up roughly 169-172% year-over-year and 19-21% sequentially, with shipments up 23% quarter-over-quarter on the Line 2 ramp at Thorn Hill. GAAP gross margin improved to (55)% to (53)%, a 16-18 point sequential gain and the eighth consecutive quarter of improvement, though margins remain deeply negative. Backlog stands at roughly $765 million (3.2 GWh) and quarter-end cash was approximately $344 million, supported by $114 million of operating inflows and an $87 million DOE loan advance. The company steered full-year 2026 revenue to the lower half of its $300-350 million range, a subtle softening despite the strong quarter.
