[Form 4] CATERPILLAR INC Insider Trading Activity

Rhea-AI Filing Summary

Caterpillar Inc. (CAT) reported an insider equity change: a Group President filed a Form 4 showing the acquisition of 14 phantom stock units on 10/24/2025 under the company’s non-qualified deferred compensation plan. The filing lists a price of $522.73 per unit.

The total reflects two components: 7 units credited to the account at $522.73 per unit and 7 units contributed pursuant to plan terms for no consideration. Following this activity, the reporting person beneficially owns 5,178 phantom stock units, held directly.

Each phantom stock unit is generally the economic equivalent of one share of Caterpillar common stock and, per the plan, will be settled 100% in cash upon retirement or separation from service. The filing notes that the number of units may change over time due to dividend accrual adjustments and the unitized fund’s mix of stock and cash.

Explanation of Responses:

1. Each phantom stock unit under the company's non-qualified deferred compensation plan as reported is generally the economic equivalent of one share of Caterpillar Inc. common stock.

2. This total includes 7 shares that were credited to the reporting person's account under the Supplemental Deferred Compensation Plan ("the Plan") at a price per share of $522.73 and 7 shares that were contributed to the reporting person's account pursuant to the terms of the Plan for no consideration.

3. The phantom stock units are to be settled for 100% in cash upon the reporting person's retirement or separation from service.

4. Includes adjustments for dividends accrued. Moreover, phantom stock units represent interests in an unfunded unitized company stock fund comprised of stock and cash, and therefore the number of phantom stock units the reporting person is deemed to own may change between any given dates due to differences in the percentages of cash and stock in the unitized fund on those dates.
