Hyliion Holdings Corp. reported first-quarter 2026 results and progress on its KARNO Power Module platform. Revenue from research and development services was $2.8 million, up sharply from $0.5 million a year earlier, driven mainly by Office of Naval Research contracts including an 800-kilowatt KARNO system for a U.S. Navy vessel.
Operating expenses fell to $13.4 million from $19.7 million, helping narrow the net loss to $11.7 million from $17.3 million. The company ended the quarter with $139.3 million in cash and investments and reaffirmed 2026 guidance of roughly $10 million in revenue and year-end cash of about $100 million.
Commercially, Hyliion completed non-recurring UL certification testing for the KARNO Power Module, signed a non-binding LOI with VFG Holdings targeting up to 250 KARNO Cores for data centers, and now has nearly 750 KARNO Cores under LOIs representing over $400 million of potential revenue.
