Executive Commentary

“We delivered another strong quarter, with revenue well above our expectations and continued progress on system performance and customer deployments,” said Thomas Healy, Founder and CEO of Hyliion. “We delivered another system to the Navy and began moving equipment to our first commercial customer site, where we expect to complete the deployment in the weeks ahead. Customer demand continues to grow across commercial and military markets, and we expect a total of approximately $50 million in new military contract awards this year. We are increasing manufacturing throughput and building the capacity and team to support higher production volumes in 2027.”

KARNO Development and Early Customer Deployments

During the third quarter, Hyliion delivered another early adopter KARNO Power Module to the U.S. Navy, where it is being used for extended operation to further validate durability while running on diesel fuel. The Company also began moving equipment to its first commercial customer site and expects to complete the deployment in the coming weeks.

Additional early adopter units are currently in assembly, including a second commercial customer unit and systems supporting the U.S. Navy’s USX-1 Defiant autonomous vessel. Hyliion now expects to complete the 800-kW system for the Navy vessel in early 2027, consistent with the Navy’s schedule for integration ahead of sea trials. The Company expects to complete the remaining early adopter unit deliveries by its fourth quarter earnings release in February 2027. The revised delivery timing reflects, in part, a component redesign to address thermal fatigue identified during extended system operation.

KARNO development continues to focus on improving system reliability, manufacturing quality and power output. Extended system operation is providing valuable data and enabling the Company to further refine system components, software controls and manufacturing processes. The Company is also seeing improvements in manufacturing quality and consistency as it incorporates lessons learned from successive system builds. Together, these efforts are supporting continued progress toward broader customer deployments.

Hyliion also remains on track for its target of producing 200 kW of 800-volt DC power from the KARNO Core by year-end. Additional enhancements to the density of the internal mesh of the regenerator, a critical component that retains heat within the system, are now being incorporated into new printed components, which the Company expects will enable achievement of the 200-kW rating.

Military and Government Progress

Hyliion continues to expand its military development programs and expects additional contract awards before the end of 2026. Following the $41.7 million U.S. Navy contract announced in July, the Company is in the final stages of negotiations on two additional awards. These include an anticipated $1 million Navy contract to evaluate KARNO technology for a new application and an approximately $7 million contract with another branch of the U.S. military.

Together with existing awards, these anticipated contracts would bring total new military contract awards for 2026 to approximately $50 million, reaching the high end of the Company’s original objective of $40 million to $50 million. During the third quarter, Hyliion also received confirmation of approximately $3 million in additional funding under its existing Navy contract supporting development of the 800-kW KARNO Power Module for the USX-1 Defiant.

As of September 30, 2026, Hyliion had $45.5 million in remaining authorized funding under existing military contracts, excluding the approximately $8 million in additional awards anticipated before year-end. The Company expects the majority of this contracted work to be performed over the next two years, providing a significant source of future revenue.

Hyliion is also pursuing additional military funding through the defense appropriations process and sees opportunities to expand into future production system deliveries as KARNO technology is validated across military applications.

KARNO Commercial Updates and Customer Demand

Customer interest in KARNO Power Modules continues to increase across military, data center, commercial and industrial markets. Hyliion continues to see growing interest from data center customers due to KARNO system’s ability to address local concerns surrounding power generation and environmental impact. The KARNO Power Module’s native 800-volt DC architecture also aligns with emerging power requirements for AI infrastructure.

Hyliion has also engaged in discussions with prospective customers regarding the manufacturing investments and production capacity needed to support larger future deployments. The Company continues to believe that approximately $1.5 million of manufacturing equipment investment can ultimately support one megawatt of annual production capacity, representing approximately $2.5 million to $3.0 million of annual revenue at current expected pricing. Beyond data centers, Hyliion sees significant opportunities in military, commercial, industrial and other prime power applications where customers are seeking alternatives to traditional grid power.

Additive Manufacturing and Production Scaling

Hyliion continues to advance additive manufacturing improvements that could increase printer speeds by up to three times through greater utilization of laser power, software enhancements and hardware modifications. The Company is also collaborating with Colibrium Additive, a GE Aerospace company, on next-generation printing systems. These advancements are expected to support Hyliion’s manufacturing expansion plans, including the anticipated resumption of printer purchases in 2027 to expand production capacity. Hyliion’s current printer capacity is expected to deliver up to 15 MW of yearly production throughput once speed enhancements are achieved.

Hyliion is consolidating manufacturing operations to Texas, including relocating six additive printers and KARNO Core assembly from Ohio, which will remain focused on R&D and multi-megawatt KARNO systems. The Company has also filled key leadership positions in Program Management, Quality and Manufacturing Engineering to strengthen operations and support increased production volumes in 2027.

Financial Highlights and Guidance

Hyliion recorded third quarter 2026 revenue of $7.5 million from research and development services, compared with $0.8 million in the third quarter of 2025. Revenue exceeded the Company’s prior expectations, primarily reflecting accelerated progress on the 800-kW KARNO Power Module being developed for the Office of Naval Research and additional funding received under that program. Cost of revenues was $6.9 million, resulting in gross profit of $0.6 million.

Operating expenses for the third quarter were $13.0 million, down 15% from $15.3 million in the third quarter of 2025. R&D expenses declined 14% to $8.7 million, primarily reflecting a continued shift toward revenue-generating work under military contracts. SG&A expenses were $4.3 million, down approximately 17% from the prior-year quarter. Hyliion reported a third-quarter net loss of $11.1 million, compared with $13.3 million in the third quarter of 2025, an improvement of 17%.

For the first nine months of 2026, revenue was $15.2 million, compared with $2.8 million in the corresponding period of 2025. Gross profit was $1.1 million, compared with $0.1 million in the prior-year period. Operating expenses declined 17% to $42.1 million, while the net loss improved 17% to $36.7 million from $44.0 million.

Net cash spending during the third quarter was $11.0 million, compared with $20.6 million in the third quarter of 2025, reflecting mostly a decline in year-over-year capital spending. Year-to-date capital spending was $2.4 million compared with $22 million in 2025. Hyliion ended the quarter with $121.4 million in cash and short- and long-term investments.

Based on stronger-than-anticipated revenue from military research and development services, Hyliion is increasing its full-year 2026 revenue guidance to approximately $18 million, compared with the previous quarter’s outlook of $15 million and $10 million at the start of 2026. The Company expects approximately $3 million in fourth-quarter revenue as work on the 800-kW Navy system nears completion and activity ramps up under the $41.7 million Navy contract awarded in July, with the majority of work under that contract expected in 2027 and 2028.

Hyliion continues to expect to end 2026 with $115 million to $120 million in cash and investments. Higher expected revenue, lower expenses, and improved working capital are anticipated to replace the proceeds previously expected from an equipment financing transaction, which the Company has elected not to pursue in 2026 given current market terms.
