Question · Q3 2025
Angel Castillo asked for an update on Cummins' capacity expansion plans, specifically regarding large diesel engines for data centers and the potential for expanding natural gas engine lines to pursue prime power opportunities. Castillo also sought quantification of the Section 232 tariff headwind in Q3 and Q4 2025 and the potential financial impact of a rebate on U.S.-manufactured engines in 2026.
Answer
Jennifer Rumsey, Chair and Chief Executive Officer, confirmed that the doubling of large engine capacity is nearing completion, primarily supporting backup power for data centers. Rumsey noted that data center revenue is expected to increase by 30-35% in 2025 and that the company is actively evaluating further capacity investments and exploring natural gas engines for prime power. Mark Smith, Chief Financial Officer, stated that the company lacks sufficient detail to quantify the Section 232 tariff headwind or the impact of potential rebates, emphasizing Cummins' strong U.S. manufacturing footprint.
