Cummins

Jennifer Rumsey became CEO of Cummins in August 2022 amid historic industry turmoil. Infatuated with electric trucks and hydrogen power, investors had bid up shares of Nikola and Plug Power, which were suddenly worth about as much as Cummins, a profit machine with more than a century of history. Then, a few months after Cummins took over, Tesla delivered its first all-electric semi truck to PepsiCo.

Rumsey, 51, an engineer running the dominant maker of diesel engines, didn't flinch. She understood that diesel fuel would be around for a long time, and that multiple green solutions would be needed down the road.

Rumsey has bold ambitions for Cummins' renewable-technology business, Accelera, organized in 2023. It accounts for about 1% of sales today, but Cummins sees growth for years to come and a path to zero truck emissions by 2050. The company will still be moving a lot of equipment then.

Meanwhile, Cummins aims to lift profit margins to 17.5% by 2030, but Rumsey might have to aim higher: Profit margins are expected to top 16% in 2025, almost three percentage points better than in 2022.

"At a time of significant global change, I'm proud to lead a team of exceptional individuals who drive innovation with purpose and collaboration," Rumsey says.
