Hyliion Holdings Corp. Q3 FY2026 earnings call

• Revenue Outlook Raised: Management raised the full-year 2026 revenue outlook to $18 million, up from previous estimates of $15 million and $10 million, driven by accelerating progress on Navy contracts.
• Early Adopter Deliveries: A unit was delivered to the Navy for extended durability testing on diesel fuel. The first commercial field deployment is nearing completion, with installation components already at the site. All early adopter systems are expected to be completed by mid-February 2027.
• Carnot Power Module Performance: The system is targeting 200 kW of 800V DC power production by year-end. A thermal fatigue issue with a printed component was identified; the team reverted to a previous reliable design while completing a root-cause redesign. Validation testing for the new part is commencing.
• Military Contract Growth: The company secured a $41.7 million contract with the Navy for two multi-megawatt modules. Additional awards totaling approximately $8 million are expected before year-end, bringing total new military awards to ~$50 million. Remaining authorized funding under existing contracts stands at $45.5 million.
• Manufacturing Capacity & Efficiency: Speed enhancements via laser power, software, and hardware changes could triple throughput. The Austin, Texas facility is being consolidated as the primary manufacturing hub, aiming for 250 MW annual capacity eventually. Current installed base, post-upgrades, targets ~15 MW annual capacity.
• Customer Demand: Strong interest exists across data centers (including hyperscalers), commercial/industrial prime power, and military applications. Over 750 units worth of Letters of Intent (LOIs) have been signed. Customers are prioritizing field performance validation and scalable manufacturing investment models.

The company reported third-quarter revenue of $7.5 million, derived entirely from research and development services. This represents a significant increase from $759,000 in the same quarter of 2025 and $4.9 million in Q2 2026. Cost of revenues was $6.9 million, resulting in a gross profit of $552,000. Operating expenses totaled $13 million, down 15% year-over-year. The net loss for the quarter was $11.1 million, an improvement from the $13.3 million net loss in Q3 2025. Year-to-date revenue through the first nine months of 2026 was $15.2 million, compared to $2.8 million in the same period of 2025.

• Full-Year Revenue: Raised to approximately $18 million for 2026, up from prior guidance of $15 million. This includes ~$3 million expected in Q4 from the wind-down of the 800 kW system work.
• Cash Position: Expected to finish the year between $115 million and $120 million, likely on the lower end due to the cancellation of a planned equipment financing transaction.
• Capital Spending: Expected to remain low in Q4 as focus shifts to optimizing existing printer fleets rather than purchasing new assets.
• Future Outlook: No specific numerical guidance provided for 2027 revenue or production volumes, but management plans to provide more detailed 2027 guidance at the next earnings call. Printer purchases are expected to resume in 2027 to support scaling.

• Operational Delays: Technical issues with component thermal fatigue caused schedule delays, though mitigated by reverting to older designs.
• Execution Risk: Scaling manufacturing from R&D prototypes to high-volume production relies heavily on successful validation of speed enhancements and additive manufacturing processes.
• Market Conditions: Unfavorable market conditions for secured debt financing forced the cancellation of a planned $10-$15 million equipment loan, impacting cash flow assumptions.
• Commercial Adoption: Success depends on proving reliability in field deployments; customer progression from pilot to volume orders requires demonstrated operational hours and certification milestones.

Q: Analyst asked about the scope of thermal fatigue issues in the reactor design and confidence in the fix. / A: CEO explained the issue was contained to micro-cracks forming during printing of a new reactor revision. They reverted to a previous stable design to maintain delivery schedules. The root cause was addressed by modifying the print file to prevent crack formation, and validation testing for the redesigned parts is beginning.

Q: Analyst inquired about commercialization timing and reliability milestones needed for broader adoption. / A: CEO stated the six-week delay in Navy system completion does not impact next year's ramp-up. Customers require several months to nine months of field data to move from initial purchase to volume orders. Next year will focus on seeding the market with data centers, military, and industrial prime power applications to build a pipeline for 2028 scale-up.

Q: Analyst asked if it is too early to dial in printer additions for 2027 given demand conversations. / A: CEO confirmed demand is strong, with LOIs for ~750 units, but exact printer volumes depend on validated throughput. Current upgrades target 15 MW annual capacity, with the Austin facility capable of 250 MW. He noted it is too early to commit to specific printer counts for 2027, promising more guidance next quarter.

Q: Analyst asked about hurdles for data center customers and the technology's ability to handle transient loads. / A: CEO identified performance proof and scalable manufacturing investment as key hurdles. He highlighted that Carnot handles spiky AI power loads well, unlike turbines. Discussions involve coupling Carnot modules with combined-cycle plants to manage transients or using them as base load for smaller centers, leveraging native 800V DC output.

Q: Analyst sought clarity on how military funding flows, specifically regarding appropriations vs. direct procurement. / A: CFO explained that current Navy revenue is largely R&D-based, funded through appropriations. However, future opportunities include non-R&D procurement for stationary power systems using different budget buckets. As the technology proves out, revenue will shift from service-based R&D to direct sales of physical power units to various military branches.
