About Hyliion

Hyliion Holdings Corp. (NYSE: HYLN) is an energy technology company that develops modular and fuel-agnostic power generation solutions. The firm has undergone a significant strategic pivot, shifting from its initial focus on electrified powertrain solutions for the commercial trucking industry to the development and commercialization of its KARNO generator technology for stationary and mobile power applications. Founded in 2015 by Thomas Healy while he was a mechanical engineering student at Carnegie Mellon University, Hyliion was initially dedicated to electrifying Class 8 commercial trucks. Healy, a serial entrepreneur with a background in motorsports, aimed to bring hybrid technology to commercial fleets to reduce emissions and fuel consumption. The company's early products included a hybrid electric axle and the Hypertruck ERX, a range-extended electric truck powertrain using a natural gas generator. A key milestone was its public listing on the NYSE in October 2020 through a reverse merger with Tortoise Acquisition Corp., a special-purpose acquisition company (SPAC), which provided approximately $560 million in proceeds to fund its growth. At the time, Healy became the youngest CEO of a public company. Facing slow adoption of electrified trucking, rising costs, and regulatory challenges, Hyliion made a decisive strategic change in late 2023. The company discontinued its powertrain business and pivoted its entire focus to the KARNO generator, a technology it acquired from GE Additive in August 2022 for $37 million. This transition involved a significant restructuring, including reducing its workforce by two-thirds, to align resources with the new focus on distributed power generation. The KARNO generator is a linear heat generator that uses a flameless oxidation process to convert heat into electricity. It is engineered to operate on over 20 different fuel sources, including natural gas, propane, hydrogen, ammonia, and waste gases, without mechanical modifications. This fuel-agnostic capability is a primary differentiator, offering customers flexibility against changing energy markets. The technology, based on the principles of a Stirling engine and enabled by additive manufacturing, is designed for high efficiency, low maintenance with few moving parts, and quiet operation. Hyliion's business model centers on selling these modular generator systems, offered in 200 kW units that can be scaled to megawatt capacity, to a variety of industries. Target markets include data centers, EV charging infrastructure, commercial and industrial facilities, and military applications, where reliable on-site power is critical.
