Executive Commentary

"I am pleased to report that we are pulling ahead our plans to begin production of our Hypertruck ERX powertrain system to the third quarter which will be followed by sales to customers later this year. While we are pleased with this progress, we also recognize the importance in today's market of conserving cash and focusing our capital resources on the most critical activities. We are therefore making strategic changes that include reducing spending, slowing the ramp-up of truck production, and restructuring agreements with initial Founders program customers," said Hyliion's Founder and CEO, Thomas Healy. "We will continue to scale and grow the company, encouraged by the opportunities for our range-extender powertrain and KARNO generator technology in the market, and will do so in a manner that maximizes shareholder value."

Hypertruck ERX System Development

Hyliion remains on schedule with Hypertruck ERX system development and commercialization work, including kick-off of extended fleet trials later in the second quarter. Assembly of the first production trucks with the Hypertruck ERX powertrain is now expected to begin in the third quarter of this year, versus late 2023 previously. Hyliion has also received ISO 9001 and 14001 certification which demonstrates our ability to deliver operational excellence.

Hyliion is also announcing strategic improvements that will help preserve cash capital as the Hypertruck ERX powertrain system is commercialized and as work continues on the KARNO generator technology. The company is reducing expenses, capital spending and changing the ramp-up of powertrain system production to reduce cash spending on working capital. Agreements with initial Founders Program customers, who will be receiving the first trucks with the Hypertruck ERX powertrain system, are being modified to simplify terms and pass through recent inflation-driven cost increases. The company expects changes to the mix of Founders Program customers and Hyliion will place initial units with more fleets so that a greater number of customers have the opportunity to experience the powertrain. Hyliion expects to deliver the first 30 trucks by year-end 2023.

KARNO Update

Progress also continues with development and testing of Hyliion's KARNO™ generator. Assembly of the first production-scale KARNO generator has been completed and was exhibited in a prototype truck during the recent Advanced Clean Transportation (ACT) Expo in Anaheim, CA last week. The vehicle is capable of being fueled with both hydrogen and renewable natural gas, offering a truly fuel agnostic solution. The company plans to showcase the KARNO truck at its investor conference in Austin on June 27^th, where attendees will have a chance to participate in a Ride and Drive event as well as learn more about stationary power applications for the KARNO generator.

Hyzon Collaboration

As reported last quarter, Hyliion and Hyzon Motors are working together to develop a fuel-cell-powered vehicle using Hyliion's electric powertrain system and Hyzon's fuel cell technology as the generator. The project remains on track for completion by the end of this year.

Financial Highlights, Operating Expense and 2023 Guidance

In the first quarter, the Company recorded $310 thousand in revenue related to Hybrid sales. The Company's first quarter operating expenses totaled $31.9 million, $6.3 million higher than a year ago, mainly due to higher research and development spending. Hyliion ended the first quarter with $385 million of cash, short-term and long-term investments, and currently has no plans to raise additional capital.

Updated forward guidance includes total operating expense of approximately $130 million and total cash consumed in operating losses, capital spending and working capital of approximately $150 million for the year, compared to the prior estimate of approximately $200 million.

Hyliion will host a conference call and accompanying webcast at 11:00 a.m. ET / 10:00 a.m. CT on Wednesday, May 10 to discuss its financial and business results, and outlook.
