Eos Energy Third Quarter 2026 Earnings Conference Call - EOS ENERGY ENTERPRISES INC

Financial Performance:

• Q3 2026 revenue reached $82.7 million, representing a 171% year-over-year increase and 20% sequential growth, driven by a 23% rise in cube shipments.
• Gross margin improved 18 points sequentially and 58 points year-over-year, marking eight consecutive quarters of improvement; adjusted gross loss narrowed to $36.8 million.
• Adjusted EBITDA was negative $63.8 million, improving 27 points sequentially and 96 points year-over-year, with revenue growth and cost reductions identified as primary drivers.
• Net income was $125 million, primarily due to non-cash fair value adjustments on warrants and debt rather than core operating performance.
• Operating expenses remained flat sequentially at $34.7 million, with approximately 20% classified as non-cash.
• Cash flow performance tracked closely with adjusted EBITDA, utilizing $106 million in net cash (offset by $87 million in DOE reimbursements), ending the quarter with $344 million total cash ($271 million unrestricted).
• Cost per cube decreased 9% on materials, 17% on direct labor, and 8% on manufacturing overhead due to operational leverage and facility consolidation.
• Related party revenue accounted for 83% of quarterly volume; management expects this ratio to decline in Q4 as unrelated backlog deliveries increase.

Guidance and Future Outlook:

• Full-year 2026 revenue guidance is reaffirmed at $300 million to $325 million.
• Q4 adjusted gross margin is projected to improve by an additional 19 to 24 points, landing between negative 20% and negative 25%, with product margins reaching negative 15% to negative 10%.
• Long-term margin targets include positive 10% cash gross margins by Q2 2027.
• 2027 guidance and specific 2027 EBITDA/cash burn numbers will be provided in the Q4 earnings call following the resolution of near-term deals.
• Expectation for significant revenue growth in 2027 as the Thornhill facility operates at full capacity with two lines running.
• Management anticipates capital expenditures (CapEx) will moderate in the coming quarters as major investments in Line 2 and Thornhill near completion.

Business Segments and Product Lines:

• Shipment volume increased 23% sequentially, with battery production up 25% and sub-assembly up 26%.
• Thornhill facility now consolidates operations; Line 2 (20% higher output per shift than Turtle Creek) is fully commercial, contributing 17% of output in Q3 compared to 1% in Q2.
• Line 1 consolidation is accelerating: Turtle Creek bipolar line production targeted for Q4, with a full battery line return expected near the end of Q1 2027.
• Dawn OS software upgrade is being implemented in the field, improving module-level control to 168 points, eliminating single-module performance bottlenecks, and enhancing round-trip efficiency to 79% (Z3 fleet).
• New product capability "Indensity Core" demonstrated ability to handle rapid load fluctuations (147+ cycles) without added heat or efficiency loss, targeting AI and industrial dynamic loads.
• Backlog ended Q3 at $765 million (3.2 GWh), up 19% year-over-year but down from Q2 due to higher shipments; 3.5 GWh in late-stage opportunities is pipeline.
• Major new contract secured: 10-hour storage project in West Virginia for Google via partner Emanate.

Market and Competitive Landscape:

• Market demand is shifting from capacity retirement to rapid capacity addition, with grid planners projecting 166 gigawatts of new demand by 2030; data centers, manufacturers, and commercial sectors are primary drivers.
• "America's Battery" positioning is critical as tax credit eligibility now requires significant domestic content; EOS systems ship with >90% American materials.
• State-level mandates are driving long-duration storage demand: California (soliciting 2 GW of 12+ hour storage), Massachusetts (5,000 MW for 4+ hour projects), and Virginia (21 GW target by 2045).
• NYSERDA bulk storage program selected less than one-third of its target in the first round; EOS projects were not selected in round one but will reapply for round two expected by year-end.
• Competition is shifting toward reliability and delivery speed; EOS differentiates via flexibility (2 to 14-hour duty cycles) and module-level control technology.
• Customer base is diversifying with six new customers closed in Q3, reducing reliance on Frontier Power USA (currently 43% of backlog) and related-party projects.

Risks and Challenges:

• Backlog fluctuation due to project timing and financing delays; over half of late-stage opportunities are currently waiting on financing.
• NYSERDA selection process risks: previous rejection in the first round highlights the competitive nature of state-level procurement.
• Transition risks associated with consolidating Turtle Creek to Thornhill, though management views the cost impact as temporary to achieve long-term efficiency.
• Dependency on related-party revenue (Frontier Power USA) which may fluctuate based on delivery schedules and project acquisitions.
• Potential warranty costs rising with volume, though management notes warranty usage has not increased proportionally.

Management Commentary and Tone:

• Tone is confident and optimistic, emphasizing "strong operating quarter," "structural cost out," and "operational leverage."
• CEO Joe Mastrangelo highlighted the strategic shift to reliability and delivery as the key differentiator over pure technology specs.
• CFO Alessandro Laggi underscored disciplined cash management, noting cash burn is tracking EBITDA and that heavy CapEx is behind them.
• Management expressed strong conviction that the Thornhill facility layout provides structural advantages over Turtle Creek, resulting in faster cycle times and better yields.
• Confidence is high regarding the 2027 roadmap, citing the success of Line 2 and the completion of major infrastructure projects as proof points for future profitability.

Analyst Questions and Answers:

• Cash & CapEx: Asked about 4Q/1Q cash burn and CapEx; CFO confirmed cash performance tracks EBITDA, CapEx will moderate as Line 2 completes, and remaining liquidity is supported by DOE grants and tax credits.
• Frontier Power USA: CEO confirmed Jay Bellows is leading the team, bringing industry experience and a pipeline of opportunities parallel to EOS's own sales efforts.
• NYSERDA: Management declined to speculate on specific project sizes but noted strong momentum in state mandates (Virginia, CA) and plans to reapply for the second NYSERDA round by year-end.
• Margins: Clarified that the 72-point margin roadmap is on track; drivers include structural material/labor cost reductions, Thornhill efficiency, and field upgrades, not just volume leverage.
• Google/Amazon Interest: CEO noted that dynamic loads (AI, steel mills) require the specific flexibility EOS provides; the Google/West Virginia deal is a prototype for similar hyperscaler engagements.
• Warranty Costs: Management clarified that warranty reserves increase with volume but actual usage/warranty claims have remained stable.

Other Key Points:

• The Z3 fleet has discharged 6.9 GWh over 4 million cycles, with round-trip efficiency averaging 79%.
• EOS systems are uniquely positioned to handle both short-cycle load smoothing (milliseconds) and long-duration energy shifting (hours) within a single asset.
• Management highlighted that "average selling prices" dropped in Q3 due to project mix, but expect them to normalize to first-half 2026 levels in Q4.
• The company is actively working to convert late-stage opportunities into backlog to meet the growing demand for long-duration, American-made storage solutions.
• CEO noted the "emotional" milestone of emptying the Turtle Creek site and moving equipment to Thornhill, symbolizing the transition to a scaled, modern manufacturing operation.
