Hyliion Holdings Reports Fourth-Quarter and Full-Year 2023 Financial Results

Feb 13, 2024

February 13, 2024 at 04:33 pm EST Share Hyliion Holdings Corp. (NYSE: HYLN) (“Hyliion”), a developer of sustainable electricity-producing technology, today reported its fourth-quarter and full-year 2023 financial results. Key Business Highlights Announced today, the KARNOTM generator is expected to qualify for up to a 40% tax credit under the Inflation Reduction Act’s Infrastructure Tax Credit (ITC) Announced today, Detmar Logistics executed a letter of intent for an initial KARNO unit to be deployed in the Permian Basin to operate on waste flare gas Executed a letter of intent to provide KARNO generators to GTL Leasing Confirmed plans to deliver initial KARNO generator units to customers in late 2024 Began printing production-intent design components of the KARNO generator Successfully tested KARNO reactor technology on unprocessed Permian Basin gas; results surpassed emissions standards by 98% for CO and 76% for NOx Appointed Govindaraj Ramasamy as Chief Commercial Officer Announced $20 million Stock Repurchase Program Ended the year with $291 million of total cash and investments Guidance of $40 to $50 million cash expenditures for KARNO development in 2024 Executive Commentary “I’m pleased to report that the company’s strategic shift to wind down powertrain operations and focus on our KARNO generator is on track, with significant achievements made in advancing our generator technology and engaging prospective customers during the quarter,” said Hyliion’s Founder and CEO, Thomas Healy. “We expect to deliver the initial KARNO generator deployment units with customers late in 2024 followed by a ramp-up in production and additional deliveries in 2025.” KARNO Commercial Updates Today, the company announced that, under the Inflation Reduction Act, the KARNO generator is expected to be characterized the same as a fuel cell, enabling customers to qualify for up to a 40% tax credit under the current ITC. Hyliion is addressing the commercial power market first with a locally-deployable 200kW generating system which it intends to deliver to initial deployment customers in late 2024. To lead these efforts, Hyliion recently hired former Cummins powergen executive, Govi Ramasamy, as Chief Commercial Officer. Hyliion also announced today that Detmar Logistics has executed a non-binding letter of intent for a KARNO generator and to be part of Hyliion’s early adopter program. Detmar, who supplied Hyliion with test gas from the Permian Basin, intends to operate their unit on waste flare gas to produce electricity at oil & gas sites, without the need for pre-treating the gas. In addition to Detmar, Hyliion also announced a non-binding letter of intent with GTL Leasing to deliver two KARNO generators for their portable electric vehicle recharging business. Other customers’ letters of intent are in place or being finalized to represent the remaining planned deployments in 2024 and initial deliveries in 2025. Hyliion plans for initial deployments to represent a broad range of applications, including vehicle charging, waste gas fuel sourcing, and prime power generation. KARNO Generator Development Hyliion is developing a revolutionary new electrical generator powered by a linear heat motor that is expected to deliver step-change improvements in performance characteristics compared to conventional generating systems, including efficiency, emissions, maintenance requirements, noise levels and fuel flexibility. The KARNO generator is enabled by the latest advances in additive manufacturing technology. Hyliion hosted a Technology Fireside Chat in December 2023 during which Thomas Healy and Josh Mook, Chief Technology Officer, explained the capabilities and advantages of the generator. Recent technological advancements include beginning to print production-intent design parts of the BETA design of the KARNO generator. The BETA generator design will go through validation throughout 2024 and then is expected to be ready for customer deployments later this year. The company also tested unprocessed flare gas that was collected from the Permian Basin and confirmed the ability for the KARNO reactor to operate on this fuel, showcasing the fuel agnostic characteristics of the generator. Recent test results on this fuel highlight that the KARNO’s flameless oxidation process is expected to surpass current EPA Tier 4 emissions standards by 98% for CO and 76% for NOx with no additional aftertreatment or catalyst needed. Powertrain Wind-Down In November 2023, Hyliion announced that it was winding down its powertrain business segment to maintain the company’s strong cash position as it furthers development of the KARNO generator technology. The company intends to retain the powertrain technology, enabling it to explore future use or sale of the technology and tangible assets. Most wind-down activities are expected to be completed in the first quarter of 2024 while efforts to monetize powertrain assets and technology continue. Financial Highlights and Guidance Fourth quarter operating expenses totaled $32.6 million, compared to $31.6 million in the prior-year quarter as the company initiated powertrain wind-down actions. Fourth quarter expenses include $11.5 million of charges directly related to the wind-down, including employee severance, contract cancellation costs, and accelerated depreciation of assets. Full-year expenses totaled $136.3 million, compared to $152.4 million for the full year in 2022. Expenses in 2022 include $28.8 million of one-time charges associated with the purchase of KARNO generator technology from GE. Cash expenditures for 2023 were $131 million, including net losses and capital investments. The company ended the year with $291 million in unrestricted cash, and short-term and long-term investments. For 2024, total cash consumed by the KARNO generator business is expected to be between $40 and $50 million, down compared to $131 million in capital consumed by the company in 2023. This estimate excludes cash payments associated with the stock repurchase program, payments associated with the ongoing wind-down of powertrain operations, and cash generated from the sale of powertrain assets and technology. Hyliion expects to achieve commercialization of the KARNO generator with the capital on hand. Projections for 2025 include growth of KARNO generator deliveries with proceeds from sales in the low double-digit millions of dollars. The company also projects gross margins to be approximately break-even or slightly negative and cash spending to grow modestly compared to 2024.
