Summary
- Carno Module Clears Commercialization Hurdles: Achieved key power, reliability, and emissions benchmarks for customer deployment.
- Demand Surges Across Verticals: LOIs representing nearly 500 units signal supply constraint risk into 2026.
- Manufacturing and Supply Chain in Focus: Scaling additive capacity and securing critical components are now central to execution risk.
Performance Analysis
Hyliion’s Q3 2025 marked a pivotal transition from R&D to early-stage commercialization, with Carno Power Module performance now meeting or exceeding customer requirements for dispatchable power, reliability, and emissions. Revenue for the quarter reached $800,000, entirely from research and development (R&D) services linked to U.S. Navy contracts, reflecting the company’s pre-commercial revenue model. Operating expenses rose to $15.3 million, largely due to increased R&D investment and the ramp in additive manufacturing activity, while SG&A costs declined, showing operational discipline amid scaling efforts.
Net loss widened to $13.3 million, driven by higher R&D and lower interest income as cash balances were deployed for capital expenditures. Year-to-date, the company has invested $22 million in capital, primarily for additive printing capacity and facility upgrades, with a cash balance of $164.7 million at quarter-end. While the revenue ramp from Carno system sales is slated for 2026, Hyliion’s current financial position supports continued development and initial commercial deployments without near-term capital pressure.
- R&D Revenue Model Persists: All reported revenue remains tied to R&D contracts, not commercial product sales.
- Operating Expense Growth: R&D and production scaling drove higher expenses, offset by SG&A efficiencies.
- Capital Allocation Targets Manufacturing: Investment focused on additive manufacturing systems and facility readiness for commercial scale.
Financial discipline and targeted investment are enabling Hyliion to bridge the pre-revenue gap and position for a commercial inflection in 2026, though execution risk now shifts to scaling production and securing supply chain inputs.

Strategic Positioning
1. Carno Power Module: Technical Validation and Regulatory Tailwinds
The Carno Power Module achieved critical technical and regulatory milestones, including sustained output above 150 kilowatts (targeting 200 kW at commercialization), NOx emissions below 2.5 ppm without aftertreatment, and 100+ days of operational reliability testing. The EPA’s determination that Carno is not an internal combustion engine removes federal permitting hurdles, expediting customer deployments and giving Hyliion a regulatory edge in distributed power generation.
2. Demand Pipeline and Vertical Expansion
Non-binding letters of intent (LOIs) now represent nearly 500 Carno units, with demand led by data center, military, and commercial facility customers. Data center operators are drawn to Carno’s native 800-volt DC output, which aligns with emerging AI infrastructure requirements highlighted by NVIDIA. The U.S. Navy’s autonomous ship program validates Carno’s low-maintenance design, and exploratory work with small modular reactor (SMR) partners could open new nuclear energy markets in the long term.
3. Manufacturing Scale and Supply Chain Resilience
Manufacturing strategy hinges on additive manufacturing scale and supply chain security. Hyliion operates 30 additive printers and is focused on throughput optimization before further capital expansion. The company is actively managing exposure to high-strength magnet shortages from China, with current inventories covering near-term needs but ongoing sourcing risk flagged as a potential constraint for volume ramp.
4. Commercialization Path and Customer Validation
UL certification is progressing, with the linear electric motor passing on the first attempt. Hyliion is prioritizing early design refinements and demonstration deployments to accelerate customer validation cycles. The company expects initial customer testing periods of six to nine months, after which LOIs could convert to firm orders, setting the stage for a more robust commercial revenue ramp in 2026.
Key Considerations
This quarter underscores Hyliion’s shift from technology risk to execution risk, as customer demand and technical validation converge on the cusp of commercialization.
Key Considerations:
- Demand Outpaces Supply: LOIs for nearly 500 units suggest Hyliion will be supply constrained through early commercialization, with data center and military verticals showing the strongest pull.
- Manufacturing Throughput is the Next Bottleneck: Optimization of existing additive manufacturing capacity takes priority over immediate capital expansion, emphasizing operational leverage and cost discipline.
- Supply Chain Fragility: Dependence on high-strength magnets from China introduces procurement risk that could impact production schedules if not mitigated.
- Validation Cycles Drive Revenue Timing: Customer testing periods and regulatory certifications (UL) will determine the pace of LOI conversion and the timing of commercial revenue recognition.
Risks
Hyliion’s near-term risk profile centers on manufacturing scale-up, supply chain exposure (especially for critical magnets), and the timing of customer validation cycles that govern LOI conversion to binding orders. Regulatory or technical setbacks, delays in UL certification, or prolonged customer pilots could defer the commercial revenue ramp. The company’s pre-commercial cash burn and reliance on R&D revenue heighten sensitivity to execution missteps as it transitions to product sales.
Forward Outlook
For Q4 2025, Hyliion expects:
- Continued R&D services revenue, with full-year 2025 revenue likely around $4 million.
- Ongoing capital investment focused on additive manufacturing optimization and facility readiness.
For full-year 2025, management maintained guidance:
- Year-end cash and investments of approximately $155 million, assuming $65 million in total expenditures.
Management highlighted several factors that will shape 2026:
- Carno system sales and commercial revenue recognition will commence in 2026.
- Additional capital may be required to fund further manufacturing expansion, though current liquidity is sufficient through commercialization.
Takeaways
Hyliion is at an inflection point, with technical and regulatory validation paving the way for initial commercial deployments. The company’s ability to convert LOIs to firm orders and scale additive manufacturing will determine the pace and magnitude of the 2026 revenue ramp.
- Commercialization Hinges on Execution: Technical risk is largely retired, but the challenge shifts to scaling manufacturing and managing supply chain constraints.
- Demand Signals Are Robust: LOIs and customer engagement across multiple verticals provide visibility, but validation cycles and supply constraints could limit near-term upside.
- Investors Should Watch for LOI Conversion Rate and Manufacturing Throughput: These metrics will be leading indicators of Hyliion’s ability to capitalize on its first-mover advantage in distributed, fuel-flexible power generation.
Conclusion
