Executive Commentary

Thomas Healy, Hyliion’s Founder and Chief Executive Officer, said, “After a strong start to the year, our team continues to execute effectively against the timelines for both Hybrid and Hypertruck ERX products. With the unveiling of our improved Hybrid powertrain and the debut of our Hypertruck ERX demo units both scheduled for the third quarter of 2021, we are at an exciting inflection point in Hyliion’s history.”

“As we make progress on the commercialization of our Hypertruck ERX, I am very pleased to announce the recent appointment of Dennis M. Gallagher as our Chief Operating Officer who will be responsible for all commercialization efforts within Hyliion. Dennis recently served as President of Jacobs Vehicle Systems, an industry-leading supplier to the heavy-duty commercial vehicle market. He brings over 20 years of tenure at Danaher, where he led various global business units and has a proven track record of commercial and operational excellence.”

“Beginning later this year, we plan to take Hypertruck ERX demonstration units on the road to showcase them with our Hypertruck Innovation Council members and other interested fleets. As fleets experience the benefits of our Hypertruck ERX firsthand, like improved driver experience, improved performance versus diesel, and the means to reduce operating costs while offering the ability to reduce carbon emissions more than any other alternative fuel option available now or in the works, we expect customer interest and excitement to continue to grow.”

Hypertruck ERX Commercialization Progress and Product Reservations

Hyliion remains on track with its Hypertruck ERX commercialization timeline, which involves showcasing demo trucks to fleets late in 2021, followed by evaluation and testing throughout 2022. The Hypertruck ERX is projected to be commercially available in late 2022 and followed by volume ramp up.

Hyliion recently announced a reservation for 300 Hypertruck ERX units from Detmar Logistics, a leading oilfield logistics company. An early adopter of electrification solutions in the industry, Detmar placed an initial order of 10 Hyliion Hybrid Electric units earlier this spring. The successful program and deployment met with positive feedback from Detmar’s operations team, drivers, and customers, and generated further interest in the Hypertruck ERX solution and a longer-term commercial relationship with Hyliion. The purchase and sale of the 300 Hypertruck ERX units is subject to the execution of a final agreement between Hyliion and Detmar.

Hypertruck ERX Long-Range Configuration Qualifies for CA’s ACT Rule

In late July, Hyliion announced a long-range variant of the Hypertruck ERX that will offer 75 miles of all-electric range. This new configuration will enable the production vehicle to qualify for zero-emission vehicle (ZEV) sales credits by meeting California’s Advanced Clean Truck (ACT) Rule. The ACT Rule, approved by the California Air Resources Board in June 2020, requires Class 8 truck tractor manufacturers to sell ZEVs in California. Truck manufacturers will be able to achieve up to a 75% ZEV sales credit by selling a Class 8 truck with the Hypertruck ERX electric powertrain. Taking a modular approach to the platform to meet OEM demand, address fleet needs and satisfy government mandates, the production Hypertruck ERX will be available in multiple configurations, including a reduced electric range model that will follow the release of the long-range version. Both configurations will offer over 1,000 miles of total range when using the onboard generator to recharge the battery pack.

Commercial Hybrid Launch

Hyliion is currently finalizing its improved Hybrid electric powertrain and is on track to launch during the latter part of 2021. This improved hybrid electric powertrain includes several enhancements to make the product more attractive to potential customers while also simplifying the installation process. After the launch of the improved Hybrid product, the company will begin to recognize revenue on the units.

Financial Highlights and Operating Expense Guidance

Hyliion ended the second quarter 2021 with $317.7 million in cash and cash equivalents on its balance sheet. Including short-term investments of $140.0 million and long-term investments of $159.7 million, Hyliion had over $617 million available to fund its current commercialization plans for its Hybrid and Hypertruck ERX powertrains.

While Hyliion expects to begin generating revenue from its improved Hybrid product after launch later this year, it does not expect the revenue generated in 2021 to be material.

Hyliion expects full year 2021 operating expenses to range between $130 million and $140 million, a reduction compared to previously disclosed guidance of approximately $140 million. This consists of SG&A and R&D expenses.
