Penske, ROUSH CleanTech, and Proterra Announce New Collaboration for Next-Generation F-650 Electric Commercial Trucks

All-electric ROUSH CleanTech F-650 to feature Proterra’s industry-leading battery technology systems

Three leaders in clean transportation solutions — ROUSH CleanTech, Penske Truck Leasing, and Proterra Inc (“Proterra”) announced a new collaboration under which Proterra (NASDAQ: PTRA) will supply its industry-leading battery technology to ROUSH CleanTech for the development of its next-generation Ford F-650 all-electric commercial truck.

ROUSH CleanTech will integrate its advanced clean technology and control systems to leverage Ford’s mediumduty
chassis and Proterra’s battery technology to Penske Truck Leasing, which will be the first customer for this
next-generation product. In addition, the three companies will collaborate on continued fleet electrification,
including charging and an ecosystem of solutions that will make the transition to electric more seamless for fleets.

The all-electric ROUSH CleanTech Ford F-650 is a purpose-built Class 6 commercial electric vehicle that is available
in several configurations including utility trucks, shuttle buses, and box trucks.
Built on the Ford’s industry leading F-650 chassis, the vehicle will be equipped with Proterra’s H Series battery
systems.

Ideal for packaging between frame rails, the Proterra H Series battery system powering the F-650 can
provide 165 kilowatt hours of energy to deliver an estimated 125 miles of vehicle range on a single charge, while
supporting an available payload of nearly 8,500 lbs. ROUSH CleanTech expects to deliver the next-generation Ford
F-650 in Q2 of 2023 to Penske Truck Leasing.

“The goal of the ROUSH CleanTech, Proterra, and Penske collaboration is to remove any and all barriers to help
fleets transition to a cleaner future,” said Todd Mouw, president of ROUSH CleanTech. “It’s clear the market is
looking for trusted brands like ours to develop innovative technologies while also supporting the entire lifecycle —
from vehicle design and development, to infrastructure assistance, after-sales customer support, and more.”

ROUSH CleanTech is backed by decades of advanced vehicle engineering controls and integration experience
including battery electric and hydrogen fuel cell from parent company, Roush Enterprises. ROUSH CleanTech’s
expertise in electrification includes production design, functional performance validation, compliance testing,
assembly set up, and vehicle second-stage manufacturing. ROUSH CleanTech has deployed more than 37,000
advanced clean technology vehicles since 2010 that have accumulated more than 2 billion miles with more than 3,000
commercial, school bus, and public transit fleets.

“We remain committed to being at the forefront of vehicle electrification and making impactful sustainability
strides within our industry. This collaboration is another step towards a more sustainable future in trucking,” said
Paul Rosa, senior vice president of procurement and fleet planning at Penske Truck Leasing. “We plan to deploy
and operate these vehicles in multiple markets.”

Penske has been operating, supporting and maintaining alternative-fueled vehicle fleets for more than 30 years,
including commercial electric vehicles for a decade. In addition to the next-generation F-650, Penske has
introduced light-duty, medium-duty, and heavy-duty electric commercial vehicles to its fleet along with its own
heavy-duty EV charging networks.
