This follows the completion of the Company’s previously announced business combination with ArcLight Clean Transition Corp.

ArcLight shareholders approved the combination at an extraordinary general meeting on June 11, 2021.

The Company has raised more than $640 million in cash from the business combination with ArcLight to fund growth initiatives, including R&D and its next-generation battery program.

We are excited to build on the strong foundation we have created over the past decade and begin this new chapter as a publicly-traded EV technology leader. We remain focused on advancing our EV technology to power the world’s best performing commercial vehicles, and believe today is a major step forward in our ability to accelerate these initiatives.”

“We are pleased to have completed our business combination with Proterra,” said Jake Erhard, the former President and CEO of ArcLight, and a Director of Proterra. “As a leader in EV technology, Proterra has significant opportunities ahead for value creation, and we are excited about the Company’s prospects as it enters the next phase of growth.”

Proterra operates manufacturing facilities in California and South Carolina, as well as a state-of-the-art R&D lab in Silicon Valley. With more than 600 vehicles on the road today, the Company’s industry-leading battery systems have been proven through approximately 20 million service miles driven, and validated through partnerships with world-class commercial vehicle manufacturers to electrify delivery vehicles, construction equipment, school buses, coach buses, and more. To date, Proterra has produced and delivered more than 300 megawatt-hours of battery systems and installed 46 megawatts of charging systems.
