Stephen Roy, president of Mack Trucks and chairman of Volvo Group North America, and RJ Scaringe, founder and CEO of Rivian, will deliver keynote addresses at ACT Expo 2026, taking place May 4-7 in Las Vegas.

Roy’s keynote, scheduled for May 5, will bring perspective on how connected systems, software-defined platforms and AI-driven capabilities are redefining today’s commercial vehicles, according to a news release. He oversees a broad portfolio of heavy-duty commercial vehicle technologies serving fleets across North America.

His keynote will explore how fleets are using connected vehicles, over-the-air updates and advanced analytics to improve uptime, optimize maintenance, and make smarter long-term equipment decisions. The session will focus on how digital intelligence is fast becoming a core driver of operational performance and customer success.

“Today’s trucks are defined by much more than hardware,” Roy 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.”

EV deployments

Scaringe’s keynote, scheduled for 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.

With thousands of electric delivery vehicles in daily operation and Rivian now offering its commercial vehicles to fleets of all sizes, Scaringe will share insight into how electrification decisions affect total cost of ownership, reliability, safety, and day-to-day operations. His remarks will highlight how vehicle design, software, and advanced driver-assistance systems support consistent fleet performance when deployed in demanding, high-utilization environments.

“Fleet electrification is happening at scale, every day,” said 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.”
