Company Announces Plans to Focus on KARNO and Wind Down Powertrain Operations, Preserving Technology for Potential Future Use or Sale

AUSTIN, Texas, November 8, 2023 – Hyliion Holdings Corp. (NYSE: HYLN) (“Hyliion”), a developer of KARNO generator and electric powertrain technologies, today reported its third-quarter 2023 financial results and announced that it will concentrate its future efforts on the KARNO generator while winding down its powertrain operations. The Company will preserve its powertrain technology for potential application in the future.

This strategic shift will help maintain the company’s robust cash position and align its KARNO generator business for future success. The Company projects to finish 2023 with approximately $285 million of available capital and estimates cash burn of approximately $40 million in 2024.

Powertrain Business Transition and Technology Preservation

With the recent receipt of CARB certification and launch of extended fleet trials, Hyliion has completed all steps on its well-publicized path to commercialization of the Hypertruck ERX powertrain. Despite these accomplishments, the Company previously announced that its Board of Directors had engaged expert advisors to explore a range of strategic alternatives for its powertrain business. The reasons for undertaking this strategic review included lower-than-expected industry adoption of electrified commercial vehicle solutions, increases in component costs, evolving regulatory requirements, and uncertainty about the ability to raise additional needed capital for ongoing investment in the business.

The Company considered a range of options and concluded that discontinuing the powertrain business and focusing on the commercialization of the KARNO generator is in the best interest of Hyliion and its shareholders. Hyliion intends to retain the powertrain technology enabling the Company to explore future use, including a resumption of powertrain commercialization or a sale of the technology and tangible assets from the powertrain division.

“The decision around our powertrain business was very difficult, but we believe it is a necessary step to safeguard our financial stability, especially given the current economic climate,” said Hyliion’s Founder and CEO, Thomas Healy. “Our focus on KARNO aligns with the growing demand for electricity. With commercial deliveries planned for the upcoming year, the KARNO generator offers a more capital-efficient path to market,” added Healy.

Exhibit 99.1
KARNO Generator Update

Hyliion remains committed to the ongoing commercialization of the KARNO generator as the Company undergoes a strategic shift to concentrate on this business segment. The Company continues to be encouraged by the substantial progress achieved in development and growing interest from potential customers to leverage the KARNO generator for diverse power generating applications.

KARNO Development Highlights:

Delivered power successfully to the grid, marking a significant achievement in ongoing development and validation
Executed customer showcases to grow demand for future deliveries
Performed simulations and in-lab testing that indicate power, efficiency, and emissions objectives for the production unit design will be achieved
Demonstrated potential for future mobility applications with Hypertruck KARNO vehicle
Moved into a new R&D and low-volume production facility near Cincinnati, OH

Hyliion anticipates its first revenue-generating deployments of the KARNO generator to occur in late 2024 and is in discussions with inaugural customers. With the strategic shift to focus on the KARNO generator, Hyliion is positioned to achieve commercialization with capital on hand.

Hyliion is planning to host a technology fireside chat later in the quarter to highlight the unique capabilities of the KARNO generator, business opportunities for near- and long-term deployments, and key development milestones.

Financial Highlights and Guidance

Third quarter operating expenses totaled $33.3 million, compared to $62.9 million in the prior-year quarter, which included one-time expenses of $28.8 million associated with the purchase of KARNO generator technology. Year-to-date expenses totaled $103.7 million, compared to $120.8 million in the prior year period. Hyliion ended the quarter with $324 million in cash, short-term and long-term investments.

Forward guidance for 2023 includes full-year operating expenses of approximately $140 million, including expenses associated with winding down powertrain operations. Hyliion expects no additional revenue from powertrain sales in 2023. Year-end cash and investments are expected to total approximately $285 million with cash burn in 2024 projected at approximately $40 million, excluding potential revenues or monetization of powertrain assets or technology.
