Cummins IncEPA proposed rule provides regulatory flexibility for phased engine launch, but final rule uncertain and shares barely moved.

Cummins announced updated plans for its Model Year 2027 North American on-highway engine launch after the U.S. EPA proposed changes to upcoming emissions rules. The company will use the proposed regulatory flexibility to gradually roll out its new HELM engine platforms, beginning limited production of its new X10 and X15 engines in January 2027, with full production expected by the third and fourth quarters of 2027, respectively. During the transition, Cummins will continue producing its current X15, X12, and L9 engines, and it reaffirmed plans to launch its next-generation B platform in January 2028 while the current B6.7 engine remains in production through 2027. CEO Jennifer Rumsey said the company's long-term product strategy remains unchanged, adding that the phased rollout is intended to improve the transition while maintaining product quality. The company also noted the production timeline may change once the EPA issues its final rule. Cummins shares were trading slightly lower, down around 0.1 percent, near 659.01 dollars in premarket trading.
