Overview
- Lirmann will take over on August 1, 2026, as Mack Trucks president, succeeding Stephen Roy, who is retiring after nearly 25 years with Volvo Group.
- He currently leads Volvo Trucks Latin America and has run the brand and the wider Group business in the region for close to a decade.
- Volvo Group CEO Martin Lundstedt praised Roy for building a platform for growth in North America, pointing to continuity in strategy under the new leader.
- The company paired the Mack Trucks change with wider adjustments to the Volvo Group Executive Board and the Mack management team.
- Mack builds all of its Class 8 trucks for North American and export markets at its Lower Macungie, Pennsylvania plant, so a smooth transition affects factory teams and customers.
