Eos Energy Reports Record Revenue Despite Losses; Sees Boost from U.S. Energy Storage Bill

Eos Energy Enterprises, a U.S.-based energy storage firm, reported a record quarterly revenue of $15.2 million in Q2 2025 — marking a 1,597% year-over-year (YoY) growth, though it fell short of analyst estimates by $9.71 million. Despite the revenue jump, the company posted a net loss of $222.9 million, a steep increase from the $28.2 million loss in Q2 2024. EBITDA loss also widened to $51.6 million.

During the earnings call, Interim CFO Nathan G. Kroeker highlighted the impact of the One Big Beautiful Bill, which preserves Section 45X production tax credits through 2029. This allows Eos to potentially generate over $90 million annually per manufacturing line at full capacity, thanks to its domestic supply chain and U.S.-based manufacturing strategy.

Though standalone storage was excluded from accelerated project eligibility timelines under the new legislation, renewable-coupled projects remain unaffected, with many scheduled to go live within 30 months. The Foreign Incentive Alignment Criteria (FIAC) further benefits Eos by incentivizing American-made systems.

Eos also sees rising demand from customers seeking non-lithium, zinc-based alternatives, especially in light of interconnection and permitting shifts. It continues its global push with a co-development pipeline with Frontier, targeting data center and long-duration storage needs, particularly in Europe and Asia-Pacific.

Eos reaffirmed its 2025 revenue guidance of $150M–$190M.
