ACT Expo 2026, Mack Trucks’ president on stage
Stephen Roy’s keynote, scheduled for Tuesday, May 5, will bring vital perspective on how connected systems, software-defined platforms and AI-driven capabilities are redefining today’s commercial vehicles. As President of Mack Trucks and Chairman of Volvo Group North America, Roy oversees a broad portfolio of heavy-duty commercial vehicle technologies serving fleets across North America.

“Today’s trucks are defined by much more than hardware,” he said. “Connected vehicles, software-defined platforms, and data-driven tools are revolutionizing the industry and helping fleets dramatically improve uptime, efficiency, and safety. ACT Expo is the place to have honest conversations about how these tools are reshaping how we approach decarbonization and sustainability and where they deliver real value.”
Rivian’s point of view on May 6
RJ Scaringe’s keynote, scheduled for Wednesday, May 6, will focus on Rivian’s expanding role in commercial transportation, including the company’s work with fleets on large-scale EV deployments, and the outlook on new vehicles and technologies that can strengthen fleet operations and financial performance.

“Fleet electrification is happening at scale, every day,” said RJ Scaringe. “I’m excited to share what we’re learning from real-world deployments and how thoughtful vehicle design, software, and data can help fleets lower costs, improve uptime, and operate more reliably in demanding environments.”
