New in FY2025

Minerals - Increased primarily due to higher shipments of aggregates and cement.

New in FY2025

Forest Products – Decreased due to lower shipments of building products, as well as lower shipments of pulp and paper products which includes the impact of both temporary outages and customer plant closures.

New in FY2025

Metals and Equipment - Increased scrap shipments were offset by lower aluminum and steel shipments, which includes the impact of plant closures, as well as lower equipment shipments.

New in FY2025

Export coal decreased due to lower shipments of metallurgical and thermal coal, which includes the impacts from outages at customer facilities.

New in FY2025

New in FY2025

- An increase of $14 million was due to higher incentive compensation costs, driven mostly by downward accrual adjustments in the prior year.

New in FY2025

- A decrease of $47 million was due to the impacts of lower rail headcount and overtime.

New in FY2025

- Net other costs increased $12 million primarily due to higher trucking headcount, including the impacts from acquiring previously independent affiliates, partially offset by other non-significant net decreases.

New in FY2025

New in FY2025

These impacts include rerouting costs.

New in FY2025

FCF before dividends decreased $995 million year-over-year to $1.8 billion primarily due to lower net earnings and the payment of $429 million of previously-postponed federal and state taxes related to the 2024 tax year.

New in FY2025

Other year-over-year decreases resulting from higher property additions, including approximately $470 million related to rebuilding the Blue Ridge subdivision, as well as a $96 million prepayment for locomotive maintenance services were partially offset by the impact of bonus depreciation and other changes in working capital.

New in FY2025

Related to tax payments, no 2025 taxes were postponed, but 2024 results included the payment of $387 million of previously-postponed taxes related to the 2023 tax year, offset by postponement of $429 million of taxes related to the 2024 tax year.

New in FY2025

These decreases were partially offset by the impact of bonus depreciation and other changes in working capital.

New in FY2025

In 2024, the payment of $387 million of previously-postponed taxes related to the 2023 tax year was more than offset by postponement of $429 million of taxes related to the 2024 tax year.

New in FY2025

The $1.0 billion decrease in net spending on financing activities compared to the prior year was driven by fewer share repurchases and higher proceeds from the issuance of long-term debt.

New in FY2025

Planned capital investments for 2026 are expected to be less than $2.4 billion.

| *Description of the Matter* | | | As of December 31, [removed: 2024,] [added: 2025,] assets depreciated under the group-life method comprised 86% of total gross fixed assets of [removed: $52.2] [added: $53.8] 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 [removed: lives, salvage values, accumulated depreciation] [added: lives] and [removed: other factors] [added: salvage values] related to [removed: group] [added: group-life] assets. Depreciation studies are performed every three years for equipment assets and every six years for road and track assets. [removed: In years when] [added: At least annually, management reviews and evaluates asset service lives and salvage values for appropriateness, which includes consideration of the most recent] depreciation studies [removed: are not performed, annual] [added: or] data reviews [removed: are] conducted by a third-party [removed: specialist and analyzed by the Company’s management to review the asset service lives.] [added: specialist.] For road and track assets and equipment assets, the most recent depreciation studies were performed in 2020 and [removed: 2022,] [added: 2025,] respectively. [removed: 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 [removed: and required the involvement of specialists] due to the nature of the methods used [removed: in the depreciation studies] to determine the [removed: useful] [added: asset] service lives and salvage values of the Company’s assets. These methods have [removed: a significant effect] [added: an impact] on depreciation expense. | | | | | | | | |

For example, we tested controls over management’s review of asset activity that could impact the estimated useful [removed: lives determined in the most recent depreciation studies of equipment and road and track assets.] [added: lives.] To test the [removed: estimated useful] [added: asset service] lives and salvage values of the Company’s group-life assets, we performed audit procedures that included, among others: [removed: obtaining the periodic depreciation studies] [added: evaluating management’s documentation to support its evaluation of asset service lives] and [removed: annual data reviews performed] [added: salvage values to assess if there have been any indicators there has been a material change; evaluating the information provided] by the Company’s third-party specialist and reviewed by management; [added: and] assessing the completeness and accuracy of the data provided by management to the third-party [removed: specialist; and including a specialist on our team to evaluate the methods used by the third-party specialist and reviewed by management in determining if any changes were necessary to the estimated useful lives and salvage values resulting from the annual data reviews. We] [added: specialist. Additionally, we] compared the assumptions used by management to those used throughout the industry and within other depreciation studies. We assessed the historical accuracy of management’s estimates via retrospective review and independently recalculated the current year depreciation rates. | | | | | | | | |
