Eos Energy Enterprises (NASDAQ: EOSE) reported fourth‑quarter 2025 revenue of $58.0 million, a 37.5% shortfall from the consensus estimate of $92.82 million. Full‑year revenue reached $114.2 million, more than seven times the $16.3 million reported in 2024, reflecting a dramatic scale‑up in production and sales.
The company posted a Q4 earnings per share of –$0.72, missing the consensus estimate of –$0.18 by roughly 300% in negative surprise. The loss was driven by the company’s continued investment in scaling its zinc‑based battery production, which has yet to reach the targeted capacity and has resulted in higher operating costs.
Adjusted EBITDA for the quarter was a loss of $71.5 million, up from a $44.6 million loss in Q4 2024. The full‑year adjusted EBITDA loss widened to $219.1 million, reflecting the cumulative impact of capital expenditures and the cost of ramping production.
Gross loss for Q4 stood at $54.4 million, while the full‑year gross loss was $143.8 million. Margin improvement of 230 basis points QoQ and 408 basis points YoY indicates that the company is gaining efficiency as volumes increase, but it remains in a loss position as it invests heavily in capacity expansion.
Eos is targeting an annualized production capacity of 2 GWh. Management noted a five‑week delay in reaching this capacity, which contributed to the revenue miss and the continued loss profile, yet the company remains on track to achieve positive contribution margins as scale improves.
For 2026, Eos guided revenue of $300 million to $400 million, below analyst consensus estimates of $471 million to $488 million. The guidance reflects management’s cautious outlook amid ongoing execution challenges and the need to control costs while scaling production.
CEO Joe Mastrangelo said 2025 was a structural turning point, noting the company’s progress in scaling production and strengthening its cash position, but expressed disappointment in missing revenue expectations. He emphasized a focus on disciplined scale and margin improvement in 2026 to transition from accelerated growth to sustainable value creation.
Investors reacted negatively, citing the significant EPS and revenue miss and the lower‑than‑expected 2026 revenue guidance as key concerns.
