## Exhibit 99.1

**Exhibit 99.1**

**HYLIION HOLDINGS REPORTS SECOND-QUARTER 2025 FINANCIAL RESULTS** 

**AUSTIN, Texas, August 12, 2025** – Hyliion Holdings Corp. (NYSE American: HYLN) ("Hyliion"), a developer of modular power plant technology, today reported financial results for the second quarter ended June 30, 2025, and provided key updates on the development and commercialization of the KARNO™ generator platform.

**Key Business Highlights**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• KARNO Power Module qualifies for 30% Investment Tax Credit (ITC) under the One Big Beautiful Bill Act (OBBBA), recognizing its role in advancing U.S. national energy security

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Production resumed with delivery of second U.S. Navy Early Adopter Unit and with two additional KARNO Power Modules nearing completion

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Successfully transitioned all linear electric motor (LEM) production in-house, improving throughput and supporting 2025 deployment targets

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Confirmed resolution of regen depowdering challenge and redesigned critical regen part to address performance

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Signed $1 billion MOU with Alkhorayef Industries as part of Saudi-U.S. commercial agreements, with initial deployment targeted for 2026 in Saudi Arabia

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Awarded Phase II SBIR contract for up to $1.5 million to advance multi-megawatt KARNO system development

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Reiterated delivery of ten Early Adopter Units in 2025, with commercialization shifting to 2026

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Recorded revenue of $1.5 million in the quarter for research and development services

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Ended Q2 with $185 million in cash and investments and expect year-end balance of approximately $155 million

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Adjusted 2025 revenue forecast to $5 to $10 million from $10 to $15 million due to expected product commercialization in 2026

**Executive Commentary**

"We are pleased that linear generators like the KARNO Power Module were recognized under the OBBBA as an emerging technology vital for advancing U.S. energy infrastructure growth," said Thomas Healy, Founder and CEO of Hyliion. "The 30% investment tax credit will incentivize more rapid adoption of fuel-flexible, clean, and efficient KARNO generators by our customers."

"During the past quarter, we addressed the significant issues that slowed deployments earlier in the year, including successfully transitioning LEM manufacturing to our Austin facility, confirming the effectiveness of a new depowdering process, and designing a new regen we believe will achieve our performance requirements. We also expect to see a near-term ramp up in the pace of Early Adopter unit deployments with our customers."

**Investment Tax Credit under OBBBA**

Under the recently enacted OBBBA, energy projects incorporating Hyliion's KARNO Power Module that begin construction in 2026 or later will qualify for a 30% ITC covering both the generator system and its associated supporting infrastructure. This tax incentive is intended to promote technologies like the KARNO system that advance national energy security objectives by delivering new sources of clean, efficient and resilient distributed power generation. The ITC

------

**Exhibit 99.1**

significantly enhances Hyliion's ability to drive KARNO adoption across key sectors, including data centers and commercial and industrial power consumers. Customers can claim the ITC on linear generator installations for a period of ten years.

**KARNO Commercial Updates**

Hyliion has resumed producing KARNO systems including delivery of its second Early Adopter KARNO unit to the U.S. Navy. Both units are undergoing testing at the Company's Cincinnati facility to validate operational capabilities to Navy specifications and to identify opportunities for design and system enhancements, consistent with Hyliion's Early Adopter program objectives. Hyliion is also nearing completion of two additional KARNO Power Modules. The first of these units is designated for UL certification, a critical step in the path to commercialization, and the second is planned for delivery to a commercial customer following initial operation in Cincinnati.

In addition, Hyliion was awarded a Phase II Small Business Innovation Research contract valued at up to $1.5 million to advance its research and development work with the U.S. Navy for shipboard and stationary applications. This contract will focus on developing software to manage and synchronize Cores within a multi-megawatt KARNO system. The U.S. Air Force has also designated the KARNO Power Module as an "awardable technology", recognizing its potential to provide power during fuel supply disruptions and positioning it as a viable solution for broader power applications across all branches of the U.S. military.

The Company also signed a strategic MOU with Alkhorayef Industries during the Saudi-U.S. Investment Forum, outlining a potential $1 billion opportunity to deploy KARNO Power Modules in Saudi Arabia. This MOU represents a significant step toward international deployment and includes plans to adapt the KARNO system to regional conditions such as high temperatures and elevated altitudes, and to operate on fuels such as LPG, ammonia and hydrogen. The MOU is non-binding and is subject to the execution of a definitive purchase agreement prior to deliveries.

**KARNO Power Module Development**

Hyliion has fully transitioned all LEM production in-house to resolve production and quality issues with a contract manufacturer that had been constraining Early Adopter deployments earlier in the year. LEM output is now ramping up to meet planned Early Adopter deployments in 2025, with additional capacity expansions underway to support higher volumes in 2026.

The Company achieved another key technical milestone by confirming the effectiveness of a new process to remove residual powder from complex printed parts. With this depowdering challenge resolved, Hyliion was able to redesign the regen component of the KARNO Core, moving to a more intricate mesh structure optimized for heat exchange inside the generator. The new design is expected to improve power output and efficiency to expected levels and has been successfully bench-tested in Hyliion's flow lab. Regens are currently being printed for a complete KARNO Core to validate performance during full-power operation.

The Company continues to expect that all ten Early Adopter customer units will be deployed this year and anticipates that the commercial launch of the KARNO Power Module will extend into 2026, instead of late 2025 as previously planned.

**Financial Highlights and Guidance**

Hyliion reported second-quarter 2025 revenue of $1.5 million, generated from research and development services performed under the Company's contract with the Office of Naval Research. Cost of sales was $1.4 million, resulting in a gross profit of $131 thousand for the quarter. No revenue was recorded in the second quarter of 2024.

Operating expenses totaled $15.8 million, compared to $14.0 million in the prior-year quarter. The increase was primarily driven by higher R&D expenses, which rose to $10.1 million, up from $8.3 million in the second quarter of 2024. This increase reflects expanded additive manufacturing activity and higher costs associated with ongoing development of KARNO Power Modules. SG&A expenses were $6.0 million, down from $6.3 million in the second quarter of 2024, due to lower facility and insurance costs. The net loss for the quarter was $13.4 million, compared to $10.9 million in the second quarter of 2024.

Year-to-date revenue was $2.0 million with gross profit of $143 thousand. No revenue or gross profit was recorded in the first half of 2024. Operating expenses were $35.5 million year-to-date, compared to $33.0 million in 2024. The increase was related to higher R&D expenses, partly offset by lower SG&A expenses and Powertrain Exit and Termination expenses compared to 2024. Net loss in the first half of 2025 was $30.7 million compared to $26.4 million in 2024.

Cash and investments at quarter-end totaled $185.3 million. Cash use in the second quarter was $13.5 million including $4.3 million for capital expenditures. The Company continues to expect full-year 2025 cash outlays of approximately $65 million. This increase reflects tariff-related cost impacts, R&D acceleration, and additional capital expenditures for expanding additive printing capacity.

Hyliion revised its 2025 revenue guidance to $5 to $10 million from $10 to $15 million to reflect expected commercialization of the KARNO product being delayed to 2026. The Company continues to forecast a 2025 year-end cash and investment balance of approximately $155 million and positive gross margins from R&D services. The Company also continues to target breakeven gross margins on a cash basis by the end of 2026, supported by increasing production volume and improved pricing and manufacturing costs.
