Nature of Operations and Basis of Presentation	A. Nature of operations Information in our financial statements and related commentary are presented in the following categories: Machinery, Power & Energy (MP&E) — The company defines MP&E as Caterpillar Inc. and its subsidiaries, excluding Financial Products. MP&E’s information relates to the design, manufacturing and marketing of its products. Financial Products — The company defines Financial Products as our finance and insurance subsidiaries, primarily Caterpillar Financial Services Corporation (Cat Financial) and Caterpillar Insurance Holdings Inc. (Insurance Services). Financial Products’ information relates to the financing to customers and dealers for the purchase and lease of Caterpillar and other equipment. B. Basis of presentation In the opinion of management, the accompanying unaudited financial statements include all adjustments, consisting only of normal recurring adjustments, necessary for a fair statement of (a) the consolidated results of operations for the three months ended March 31, 2026 and 2025, (b) the consolidated comprehensive income for the three months ended March 31, 2026 and 2025, (c) the consolidated financial position at March 31, 2026 and December 31, 2025, (d) the consolidated changes in shareholders’ equity for the three months ended March 31, 2026 and 2025 and (e) the consolidated cash flow for the three months ended March 31, 2026 and 2025. The financial statements have been prepared in conformity with generally accepted accounting principles in the United States of America (U.S. GAAP) and pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Interim results are not necessarily indicative of results for a full year. The information included in this Form 10-Q should be read in conjunction with the audited financial statements and notes thereto included in our company’s annual report on Form 10-K for the year ended December 31, 2025 (2025 Form 10-K). The December 31, 2025 financial position data included herein is derived from the audited consolidated financial statements included in the 2025 Form 10-K but does not include all disclosures required by U.S. GAAP. Certain amounts for prior periods have been reclassified to conform to the current period financial statement presentation. Cat Financial has end-user customers and dealers that are variable interest entities (VIEs) of which we are not the primary beneficiary. Our maximum exposure to loss from our involvement with these VIEs is limited to the credit risk inherently present in the financial support that we have provided. Credit risk was evaluated and reflected in our financial statements as part of our overall portfolio of finance receivables and related allowance for credit losses. See Note 11 for further discussions on a consolidated VIE. Long-term receivables - trade and other in the Statement of Financial Position includes $850 million and $377 million at March 31, 2026 and December 31, 2025, respectively, for recoveries from over-payments made during the importation process. Current assets: Receivables - trade and other includes $154 million at March 31, 2026. There were no amounts included in Current assets: Receivables - trade and other at December 31, 2025. On February 20, 2026, the U.S. Supreme Court ruled that tariffs imposed under the International Emergency Economic Powers Act (“IEEPA”) on goods imported into the United States were unauthorized. As of March 31, 2026, total IEEPA tariff costs were approximately $1.0 billion. The ruling did not address potential refunds, and therefore the ultimate availability, timing and amount of any potential refunds of these tariffs is highly uncertain. Based on the current facts and circumstances, we have determined that recovery of any funds is not probable. We will continue to monitor developments related to U.S. and foreign import and export policies that could impact our consolidated results of operations, financial position and cash flows.
