Key Business Highlights<\/b><\/p>\n Executive Commentary<\/b><\/p>\n \n“The first quarter delivered tangible progress against the deployment-and-commercialization plan we outlined for 2026, including completion of UL non-recurring testing on the KARNO Power Module, a new data center partnership with VFG Holdings, demonstrated multi-fuel flexibility, and four times the revenue of the prior quarter,” said Thomas Healy, Founder and CEO of Hyliion. “Our focus for the balance of the year remains on execution as we work toward commercialization of the KARNO Power Module by year end.”<\/p>\n Product Performance and Readiness<\/b><\/p>\n \nHyliion successfully completed the non-recurring UL certification testing of the KARNO Power Module, removing a key gating item for delivering early adopter units to customer sites. The testing covered three subsystems: the linear electric motor, the battery system, and the complete Power Module, with each undergoing separate UL certification. Individual KARNO Power Modules will still undergo a final operating test prior to receiving their nameplate certification, but the underlying non-recurring tests do not need to be repeated. Later in the year, the company expects to advance to facility-level certification, which will eliminate the need for individual unit sign-off and support production at scale.<\/p>\n \nHyliion continues to operate KARNO units at its Cincinnati facility and is advancing toward the full 200-kilowatt design power rating. During the quarter, the team conducted isolated testing of new software and component improvements that yielded additional power and efficiency gains. Hyliion plans to incorporate these and other advancements into the product over the coming quarters and remains on track to reach the full design power rating by year end.<\/p>\n \nFuel flexibility remains a key differentiator of the KARNO platform. During the first quarter, Hyliion demonstrated dynamic, in-operation fuel switching across diesel, natural gas, and hydrogen on a single KARNO reactor without shutting the system down. This capability is particularly relevant for applications that require on-site fuel resiliency, such as data centers operating primarily on pipeline natural gas with diesel as backup, and defense operations where fuel availability shifts in the moment.<\/p>\n KARNO Commercial Updates<\/b><\/p>\n \nHyliion remains on track to complete deployment of the approximately 10 early adopter units during 2026 and commercialize the KARNO Power Module by year end. With UL non-recurring testing now complete, Hyliion will begin transitioning units to customer sites over the next couple of quarters.<\/p>\n \nHyliion and VFG Holdings, LLC entered into a non-binding Letter of Intent (\u201cLOI\u201d) establishing a strategic partnership focused on deploying KARNO Power Modules for advanced next-generation data center applications. The parties intend to pursue deployment opportunities totaling up to 250 KARNO Cores, or 50 megawatts of power generation capacity, over the next five years. VFG develops turnkey data center solutions, including power infrastructure, compute systems, site development, and financing. The parties expect to provide additional updates regarding the collaboration and initial deployment opportunities in future periods.<\/p>\n \nHyliion has commenced the build of an 800-kilowatt KARNO Power Module for installation on an unmanned U.S. Navy vessel under existing Office of Naval Research contracts, with completion expected in 2026. The 800-kilowatt architecture also serves as the foundational building block for the company’s data center offering, scalable to 2.4 and 3.2 megawatts to match the modular power requirements of data center customers.<\/p>\n \nHyliion is now engaged with multiple branches of the U.S. military beyond the Navy and Air Force, driven by interest in the platform’s true fuel-agnostic operation, low maintenance, and low acoustic and thermal signature, which suit autonomous operations and mobile power generation. The company expects to sign $40 to $50 million in additional military contracts during 2026, on top of the approximately $20 million in ONR contracts currently being executed, subject to customary government contracting processes.<\/p>\n \nCustomer interest in the KARNO platform continues to grow. As of quarter end, Hyliion had executed non-binding letters of intent for nearly 750 KARNO Cores across data center, military, prime power, and other applications, representing more than $400 million of potential revenue at current pricing.<\/p>\n Financial Highlights and Guidance<\/b><\/p>\n \nHyliion recorded first-quarter 2026 revenue of $2.8 million from research and development services, compared to $0.5 million in the first quarter of 2025 and $0.7 million in the fourth quarter of 2025. The significant growth reflects an acceleration of work under the company’s contracts with the Office of Naval Research, including the build of the 800-kilowatt KARNO Power Module being delivered for the Navy. Cost of revenues was $2.6 million, resulting in a gross margin gain of $0.2 million for the quarter.<\/p>\n \nOperating expenses for the first quarter were $13.4 million, compared to $19.7 million in the first quarter of 2025, primarily reflecting lower research and development spending. R&D expense was $7.7 million, down 37% from $12.2 million in the first quarter of 2025. The reduction reflects a shift of activity into revenue-generating work for the Navy as well as approximately $1.9 million related to the production and capitalization of inventory that the company expects to utilize in future periods for building KARNO systems for the Navy. The Powertrain Exit and Termination line reflected a credit of $0.4 million during the quarter compared to expenses of $1.4 million in the first quarter of 2025, primarily reflecting ongoing asset sales related to the former powertrain business that are largely complete. SG&A expenses were relatively flat year over year.<\/p>\n \nHyliion reported a first-quarter 2026 net loss of $11.7 million, a 32% improvement from the net loss of $17.3 million reported in the first quarter of 2025. Total cash expenditures were $13.0 million during the quarter, including capital spending of $1.9 million related primarily to additive printing machines and facility investments to support printer operations. Cash generated from asset sales was $1.6 million. Hyliion ended the first quarter with $139.3 million in cash and short and long-term investments.<\/p>\n \nLooking ahead to the balance of 2026, Hyliion is reaffirming its prior guidance of approximately $10 million in full-year revenue from R&D services and potential initial commercial customer sales following commercialization of the 200-kilowatt KARNO Power Module, which is expected late in the year. The company expects total cash use during the year to be approximately $50 million, resulting in a year-end 2026 cash and investments balance of approximately $100 million. The reduced cash use forecast compared to 2025 reflects higher revenue, expense control, lower capital spending, and approximately $10 million of planned equipment financing. The company continues to believe its current capital position is sufficient to fund operations through commercialization of the KARNO Power Module.<\/p>\n About Hyliion<\/b><\/p>\n \nHyliion is committed to creating innovative solutions that enable clean, flexible and affordable electricity production.
