Munich, July 1, 2021 – The TRATON GROUP is welcoming a new member of the family: Navistar. The certificate of merger that was submitted today successfully completes the closing and means that the merger between the US commercial vehicle manufacturer and TRATON is complete. The TRATON GROUP now holds all Navistar common shares. Navistar is to be delisted and deregistered with the SEC during July 2021. The addition of Navistar as the newest member of the TRATON GROUP marks the beginning of a new era.

“Today is a sensational day for the TRATON GROUP and for our new colleagues at Navistar joining the global TRATON family. From this day on, we will be working side by side to bring sustainable transportation of the future one step closer. This is something the entire group is looking forward to,” said TRATON CEO Matthias Gründler, adding: “The fact that this merger has been implemented so quickly and smoothly, despite the obstacles presented by the COVID-19 pandemic, is testament to the impressive team work on both sides of the Atlantic. I would like to thank each and every one involved.”

“Over the past five years, Navistar and the TRATON brands have worked very well together and it is exciting to become now part of the global TRATON GROUP,” said Navistar President and CEO Persio Lisboa. “Our common understanding of the future of transportation and our joint heritage create a very solid basis for our common way forward. The transport industry is changing rapidly. And together we will shape this change – for the sake of our customers. The Navistar team is ready for the next step of collaboration.”

A strategic alliance has been in place between TRATON and Navistar since 2017, with both partners benefiting from the considerable value generated by enhanced purchasing power and the integration of new technologies. As a new brand of the TRATON GROUP, Navistar will be in a better position to meet the growing requirements of the market and to improve its customer offering even further, especially with respect to the transition to electric mobility and the establishment of autonomous driving.
