Economic Volatility and Demand Fluctuations: Global economic downturns or industry-specific slowdowns in key sectors like trucking, construction, mining, or power generation can significantly reduce demand for Cummins' engines and power solutions.

Regulatory and Environmental Compliance Costs: Increasingly stringent global emissions standards and environmental regulations require continuous, substantial research and development investment, which can increase production costs and potentially impact product competitiveness.

Intense Competition and Market Share Erosion: Cummins faces significant competition from other engine manufacturers and power solution providers, which could lead to pricing pressure, reduced sales volumes, or loss of market share.
