Eos Energy Enterprises (EOSE) shares fell over 9% to a new 52-week low on Thursday, July 16, 2026. The decline followed the release of preliminary second-quarter financial results.

The company expects record quarterly revenue between $68 million and $69 million. It also reported a record backlog of approximately $807 million.

Revenue guidance fell short of Wall Street estimates. Eos forecast a substantial gross margin loss between 69% and 73%.

A recent capital raise involving a registered direct offering and rights offering further pressured the stock. These financing activities sparked investor concerns regarding potential share dilution.
