U.S.-based energy storage solutions provider Eos Energy Enterprises reported a record quarterly revenue of $15.2 million in the second quarter (Q2) of 2025, a 1,597% increase year-over-year (YoY), driven by increased production volumes. However, it still missed analysts’ expectations by $9.71 million.

The company reported a loss per share of $0.37, missing the analysts’ estimate by $0.25.

It posted an earnings before interest, taxes, depreciation, and amortization (EBITDA) loss of $51.6 million compared to a loss of $29.1 million in the corresponding quarter last year.

Eos reported a net loss of $222.9 million compared to a net loss of $28.2 million in Q2 2024.

During the earnings call, Nathan G. Kroeker, Interim CFO and Chief Commercial Officer at Eos, emphasized the positive impact of the recently passed One Big Beautiful Bill (budget Reconciliation Bill) on the energy storage sector.

According to Kroeker, the bill preserves the Section 45X production tax credits in full through 2029, allowing the company to generate over $90 million annually per manufacturing line when operated at capacity. He said this benefit can be attributed to Eos’ strategic decision over the past seven years to localize its supply chain and invest in domestic manufacturing.

While the legislation accelerated eligibility dates for wind and solar projects, standalone energy storage was excluded from these changes. Kroeker stated that Eos has not seen any meaningful impact on its pipeline so far, as most of its renewable-coupled projects are scheduled to come online within the next 30 months.

The company said that the foreign incentive alignment criteria (FIAC) provisions in the bill have further strengthened its position by incentivizing American-made storage systems, aligning well with Eos’ supply chain and manufacturing strategy, which sources over 90% of materials domestically.

The removal of policy uncertainty is expected to accelerate project momentum. Kroeker noted that Eos is already witnessing increased customer activity and interest, particularly from stakeholders looking to pivot away from lithium-based storage technologies. Some customers are exploring interconnection and permit changes to transition to Eos’ zinc-based solutions due to FIAC-related constraints or other strategic preferences.

The company is co-developing a broader pipeline with Frontier, aimed at meeting data center energy demands in Europe and addressing long-duration storage needs in the Asia-Pacific region. Eos reaffirmed its full-year 2025 revenue guidance, projecting between $150 million and $190 million.

Eos had reported a 58% YoY increase in revenue from $6.6 million to $10.5 million in Q1 2025, missing analysts’ expectations by $1.31 million.
