*Adjusted Operating Results*

New in FY2024

Management believes that adjusted operating income, adjusted operating margin, adjusted net earnings, and adjusted net earnings per share, assuming dilution are important in evaluating the Company's performance and for planning and forecasting future business operations and future profitability.

New in FY2024

These non-GAAP measures provide meaningful supplemental information regarding operating results because they exclude the fourth quarter 2024 non-cash impairment of Quality Carriers' goodwill, which is a significant item that is not considered indicative of future financial trends.

New in FY2024

The goodwill impairment was tax effected using rates reflective of the applicable tax amounts related to the impairment charge.

New in FY2024

These adjusted results should be considered in addition to, rather than as a substitute for, the Company's GAAP operating results.

New in FY2024

The following tables reconcile the Company's GAAP operating results for the year ended December 31, 2024 to adjusted operating results (non-GAAP measures).

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING [removed: FIRM, *continued*][added: FIRM]

Rewritten

| *Description of the Matter* | | | As of December 31, [removed: 2023,] [added: 2024,] assets depreciated under the group-life method comprised [removed: 84%] [added: 86%] of total gross fixed assets of [removed: $50.3] [added: $52.2] billion. As discussed in Note 6 of the consolidated financial statements, the group-life method aggregates assets with similar lives and characteristics into groups and depreciates each of these groups as a whole. When using the group-life method, an underlying assumption is that each group of assets, as a whole, is used and depreciated to the end of the group’s recoverable life. The Company utilizes different depreciable asset categories to account for depreciation expense for the railroad assets that are depreciated under the group-life method. Under the group-life method, depreciation studies are conducted by a third-party specialist and analyzed by the Company’s management to review asset service lives, salvage values, accumulated depreciation and other factors related to group assets. Depreciation studies are performed every three years for equipment assets and every six years for road and track assets. In years when depreciation studies are not performed, annual data reviews are conducted by a third-party specialist and analyzed by the Company’s management to review the asset service lives. For road and track assets and equipment assets, the most recent depreciation studies were performed in 2020 and 2022, respectively. These studies were evaluated by the Company’s management in the current year through an annual data review. Auditing depreciation expense for assets subject to the group-life method was complex and required the involvement of specialists due to the nature of the methods used in the depreciation studies to determine the useful service lives and salvage values of the Company’s assets. These methods have a significant effect on depreciation expense. | | | | | | | | |

Subsequent to 2024, the Company entered into two fixed-to-floating interest rate swaps classified as fair value hedges in January 2025.
