Proterra Debuts on NASDAQ
This follows the completion of the company’s previously announced business combination with ArcLight Clean Transition Corp., a special purpose acquisition company, that resulted in Proterra becoming a publicly-listed company.

To date, Proterra has produced and delivered more than 300 megawatt-hours of battery systems and installed 46 megawatts of charging systems. Its fleet of zero-emission, electric transit buses have displaced more than 100 million pounds of CO2 tailpipe emissions.
Proterra
Proterra Inc.’s shares of common stock and warrants began trading on the Nasdaq Global Select Market, under the new ticker symbols “PTRA” and “PTRAW,” respectively. This follows the completion of the company’s previously announced business combination with ArcLight Clean Transition Corp., a special purpose acquisition company, that resulted in Proterra becoming a publicly-listed company. ArcLight shareholders approved the combination at a general meeting earlier this month.
Proterra 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. As a public company, Proterra is well-positioned to deliver on its mission to enable the electrification of commercial vehicles, helping to reduce pollution and protect public health while combating the global climate crisis.
“As demand for zero-emission solutions continues to grow around the globe, we are proud to be meeting our customers’ needs with our industry-leading EV technology,” said Proterra CEO Jack Allen. “Today’s milestone is a testament to the hard work of our team and the support of our valued customers, partners, and investors. 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.”
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. Its fleet of zero-emission, electric transit buses have displaced more than 100 million pounds of CO2 tailpipe emissions.
