Revenues, operating profit, total assets, and long-lived assets for U.S. and Foreign operations | Revenues and operating profit (loss) for our U.S. and foreign operations for the years ended December 31, 2024, 2023, and 2022 are presented below. Our primary foreign operations are in Mexico, while Canadian operations are not significant in relation to the Consolidated Financial Statements. The decreases in foreign operations revenue from 2022 to 2023 are largely due to the sale of the storage tanks business. The operating profits presented below exclude the gain on sale of the storage tanks business. See Note 2 Acquisitions and Divestitures.
