Caterpillar shares fell Thursday after-hours after the company warned of steeper tariff headwinds for the rest of 2025. In a regulatory filing, Caterpillar said incremental tariffs announced this year are expected to cost between $500 million and $600 million in the third quarter, with a total impact of $1.5 billion to $1.8 billion for 2025. While the company reaffirmed its revenue outlook from its second-quarter report, it now expects its full-year adjusted operating profit margin to land near the low end of its target range. Caterpillar shares were down 3.43% after-hours trading on Thursday.
