    Executive summary

    Eos Energy Q2 FY26 — Record Shipments, Backlog Growth, and Strategic Consolidation

    Eos Energy delivered record revenue and backlog in Q2 FY26, driven by increased product shipments and operational efficiencies. The company is strategically consolidating manufacturing into its Thorn Hill facility, a move expected to enhance future profitability and scale, despite a near-term adjustment to the full-year revenue outlook. Strong commercial momentum, particularly in data center and long-duration segments, is converting pipeline opportunities into projects, supported by the Frontier Power USA joint venture.

    Highlights

    5
    • Achieved record revenue of $68.8 million, up 351% year-over-year and 21% sequentially.

    • Secured record backlog of $807 million, with 6 new customers and 2 repeat customers placing orders.

    • Adjusted gross margin improved by 7 points sequentially to negative 52%, marking the seventh consecutive quarter of improvement.

    • Total cash balance at quarter-end was $364 million, with operational cash use closely matching adjusted EBITDA loss.

    • Fleet cumulative discharge energy reached 6.5 gigawatt hours, with Z3 fleet average round trip efficiency at 78% and top performance crossing 90%.

    Concerns

    4
    • Tightened FY26 revenue outlook to $300 million to $350 million due to accelerated manufacturing consolidation, trading near-term revenue for future margin expansion.

    • Adjusted EBITDA loss was $71.4 million, with a margin of negative 104%.

    • Consolidated manufacturing overhead per cube was temporarily impacted by underutilization of the Thorn Hill facility as Line 2 ramped up.

    • Net loss for the quarter was $276 million, primarily driven by noncash fair value adjustments related to capital structure.

    Capital programs

    1
    Thorn Hill Manufacturing Consolidationunderway
    Period spend: Modest investment
    Start: Q3 FY26

    Benefit: 10-15% reduction in conversion costs

    Accelerating the consolidation of operations into the Thorn Hill facility, including upgrading Line 1. Expected payback period of approximately 9 months. This positions the company for margin improvement in 2027.

    Risks & headwinds

    4
    Near-term revenue impact from manufacturing consolidationFY26

    Tightened FY26 revenue outlook to $300M-$350M

    Mitigation: Accelerated consolidation for long-term cost reduction and margin expansion; Line 1 will be down for upgrades during the move.

    Underutilization of Thorn Hill facilityQ2 FY26

    Temporarily impacted consolidated manufacturing overhead per cube

    Mitigation: Expected to diminish significantly by Q4 as throughput increases and the line matures; adding shifts and increasing utilization.

    Cost pressure from project execution investmentsQ2 FY26

    Offset some manufacturing gains, created near-term margin pressure

    Mitigation: Deliberate investment to strengthen execution ability as deployments scale; expected to diminish significantly by Q4 as work is completed and activities are brought in-house.

    Volatility in reported earnings due to noncash fair value adjustmentsQ2 FY26

    Net loss of $276 million

    Mitigation: These adjustments are primarily related to mark-to-market revaluation of warrants and derivative liabilities, not reflecting operating performance.

    CurrentLine 1 will be down during the move and upgrade
    TargetProgress on relocation and integration of Line 1 into Thorn Hill

    Why it matters

    Successful consolidation is key to achieving targeted conversion cost reductions and setting up 2027 for volume growth and margin expansion.

    As we move through the third quarter, we're evaluating the timing of📎 consolidating Line 1 in the Thorn Hill.

    Q&A highlights

    6

    Clarify the assumptions for the low and high ends of the updated FY26 revenue guidance, specifically regarding Thorn Hill's production ramp and Line 1's contribution.

    The low end of the FY26 revenue guidance assumes maintaining the June run rate, while the high end depends on Thorn Hill reaching full 24/7 operation by the end of Q4, not necessarily Line 1 coming back online at Thorn Hill within the year.

    So lower end is basically continue the run rate of June throughout the rest of the year. to get to the $300 million. The higher end of that is to not so much get Line 1 up and running in Thorn Hill but to get Thorn Hill the full 24/7 operation by the time we get into the -- at the end of the fourth quarter.

    Detailed Narrative

    01

    Strategic Manufacturing Consolidation

    Eos is accelerating the consolidation of its manufacturing operations into the Thorn Hill facility, a strategic decision to trade near-term revenue for long-term cost reduction and margin expansion. This involves moving and upgrading Line 1, which will temporarily impact production but is expected to deliver a 10-15% reduction in conversion costs with an approximate 9-month payback period. The goal is to simplify operations and achieve greater scale and efficiency in 2027.

    02

    Operational Efficiencies and Cost Reduction

    The company achieved significant operational improvements, with cube output increasing 20% sequentially and reaching an annualized production rate of approximately 1.5 GW in June. Material costs improved 10% sequentially, and direct labor cost per cube declined 20%. Scrap dollars were down 63% in the first half of FY26 compared to all of FY25, validating the scaling of the manufacturing platform. Line 2 at Thorn Hill is already demonstrating superior performance, with battery cycle times 10% faster and bipolar cycle times 11% faster than Line 1.

    03

    Frontier Power USA Driving Project Conversion

    Frontier Power USA, a joint venture with Cerberus, is successfully executing its strategy to accelerate project deployment and generate reference hours. The first project, accounting for roughly 80% of Q2 revenue, demonstrated the vehicle's ability to get projects into the field sooner, with an expected mid-teen return. Frontier Power USA has $263 million in gross proceeds, targeting $1 billion in project deployment, with 1.8 GWh under construction and first projects expected online by Q3 2027.

    04

    Expanding Market Opportunity and Pipeline

    The U.S. storage market is evolving to favor Eos's technology, particularly with load growth from data centers and electrification. The PJM grid operator, serving 65 million people, has seen prices hit the ceiling in three consecutive capacity auctions. Virginia has carved out 4.5 GW for 10+ hour resources, totaling 45 GWh at minimum duration. Eos's pipeline stands at $24.6 billion (112 GWh), up 31% YoY, with 51% of opportunities being 8 hours or longer and 32% related to data centers.

    05

    Fleet Performance and Technology Advancement

    The Eos fleet has cumulatively discharged 6.5 GWh of energy, with the Z3 fleet operating at an average round trip efficiency of 78% (across a 20-120% state-of-charge window). The top performance of the Z3 fleet has crossed 90% efficiency, demonstrating the technology's entitlement. The company continues to improve performance through software upgrades (DawnOS) and learning from 3.9 million fleet cycles, with a focus on reducing variation and consistently delivering high efficiency.

    06

    Financial Discipline and Margin Path

    Operating expenses remained essentially flat sequentially at $35 million, while revenue increased 21%. SG&A was reduced by 4%, and R&D increased by 46% to invest in future software capabilities. The company outlined a clear path to over 72 points of adjusted gross margin improvement over the next 12 months, driven by material cost reductions, conversion cost efficiencies from Thorn Hill, improved project and field services, and continued yield improvements.
