Negatives

• Continued significant net losses, with $11.1 million for the quarter and $36.7 million for the nine months ended September 30, 2026.
• Delay in the completion of early adopter customer deliveries of the KARNO Power Module, now expected between late 2026 and early 2027, due to a redesign of a critical component (reactor).
• Operating expenses remain substantial, with total operating expenses of $13.0 million for the three months and $42.1 million for the nine months ended September 30, 2026.
• Interest income has decreased significantly, down 29.9% for the quarter and 36.2% for the nine months, due to a decline in the investment balance.
• The company has a history of negative cash flows from operating activities since inception.
• Two securities class action lawsuits and one shareholder derivative action have been filed against the company and its officers/directors.

Risks

• The company is subject to ongoing securities class action and shareholder derivative lawsuits, which are costly and could adversely affect reputation and stock price.
• Delays in the commercialization and delivery of the KARNO Power Module could impact revenue generation and market adoption.
• The company's ability to secure future funding, potentially through its at-the-market offering program or other arrangements, is crucial for continued operations and growth.
• Reliance on government contracts (ONR) carries risks, including potential cancellation by the U.S. government.
• The company is dependent on certain single-source suppliers for components, creating supply chain risk.
• The KARNO Power Module technology is still under development, and certain stated performance capabilities may not be available at initial commercialization.
• The company has not yet commercialized the KARNO Power Module and continues to incur net losses, raising going concern considerations if future funding or revenue generation is not achieved.

Future Outlook

The company expects to continue incurring net losses in the short term as it executes strategic initiatives, including completing the development and commercialization of the KARNO Power Module. Customer deployments are anticipated to continue throughout 2026. Future funding requirements will depend on R&D efforts, product offerings, sales growth, working capital needs, and manufacturing plans. The company expects to seek additional capital in the future to accelerate investments in production capacity.

Management Comments

• "We believe that ongoing engineering improvements are expected to increase the KARNO Power Modules efficiency to 50% or higher in future design iterations."
• "We anticipate that the KARNO Power Module will initially achieve an electrical generating efficiency of approximately 45%, calculated by considering the usable power output in relation to the energy from the fuel source."
• "The KARNO Power Module is designed for continuous flameless oxidation of the fuel at lower temperatures and extended reaction times. As a result, the KARNO Power Module is anticipated to achieve ultra-low levels of emissions, with NOx and CO emissions expected to be reduced by over 95% compared to best-in-class diesel or natural gas engines."
• "We believe that Hyliions KARNO Power Module is an innovative solution in the emerging distributed generation space, offering a reliable power generator that combines high efficiency, fuel flexibility, and low emissions."
• "The need to retrofit affected units will delay completion of our early adopter customer deliveries beyond our previous 2026 target. We now expect to complete and deliver the approximately 10 early adopter units between late 2026 and early 2027."

Industry Context

StockSavvy.ai notes that Hyliion's focus on fuel-agnostic, high-efficiency power generation aligns with the growing demand for distributed power solutions driven by data center expansion, electrification, and grid modernization efforts. The company's technology aims to address limitations of conventional generators in terms of emissions, maintenance, and fuel flexibility, positioning it within a competitive landscape that includes traditional power generation and emerging technologies like fuel cells.

Comparison to Industry Standards

• The KARNO Power Module is anticipated to achieve an electrical generating efficiency of approximately 45%, with ongoing improvements expected to reach 50% or higher. This compares favorably to conventional diesel or natural gas generators which typically operate between 25% to 40% efficiency, and the U.S. electrical power grid at 33% to 40%.
• Emissions from the KARNO Power Module are expected to be reduced by over 95% compared to best-in-class diesel or natural gas engines, meeting stringent standards like SCAQMD Rule 1110.3 without aftertreatment.
• Maintenance costs for conventional generators can range from 5% to 20% of total operating costs, whereas the KARNO Power Module's simplified design with minimal moving parts is expected to significantly reduce maintenance requirements and costs.
• The KARNO Power Module's native 800V DC architecture is noted as simplifying power system design and enhancing site resiliency for data centers, a key market segment.

Legal Proceedings

• A securities class action lawsuit captioned Gustavo Olmeta v. Hyliion Holdings Corp., et al. remains pending in the U.S. District Court for the Western District of Texas, alleging materially false or misleading statements or omissions concerning a non-binding letter of intent with VFG Holdings, LLC.
• A shareholder derivative action captioned Jonathan Clark v. Thomas Healy, et al. was filed in the U.S. District Court for the Western District of Texas, alleging breaches of fiduciary duty, waste of corporate assets, and other claims related to the VFG Holdings letter of intent and oversight deficiencies.
• The company believes the claims in these lawsuits are without merit and intends to defend against them vigorously.
• Additional lawsuits asserting similar allegations may be filed.

Related Party Transactions

• The company entered into a consulting agreement with Gustanski Technical Services LLC, an entity controlled by Mary Gustanski, a member of the Board of Directors, for technical and strategic advisory services at $25,000 per month plus expenses.

Stakeholder Impact

• Shareholders may be impacted by the continued net losses, the delay in product commercialization, and the ongoing legal proceedings, which could affect stock price.
• Customers (including the U.S. Navy) are impacted by the delay in KARNO Power Module deliveries.
• Suppliers may be affected by the company's ongoing R&D and manufacturing plans, including potential acceleration of additive printer purchases.
• Creditors are indirectly impacted by the company's financial performance and liquidity position.

Next Steps

Key Dates

Recommendation

Hyliion Holdings Corp. shows promising technological advancements in its KARNO Power Module and significant revenue growth from R&D services, particularly from government contracts. However, the continued substantial net losses, coupled with a delay in product commercialization and ongoing legal challenges, warrant a cautious approach. The company's ability to execute on its development roadmap and secure future funding are key factors. A 'hold' recommendation reflects the balance between the potential of its technology and the significant execution risks and financial uncertainties.
