Opinions on the Consolidated Financial Statements and Internal Control Over Financial Reporting

We have audited the accompanying consolidated balance sheets of Norfolk Southern Corporation and subsidiaries (the Company) as of December 31, 2023 and 2022, the related consolidated statements of income, comprehensive income, cash flows, and changes in stockholders’ equity for each of the years in the three-year period ended December 31, 2023, and the related notes and financial statement schedule of valuation and qualifying accounts as listed in Item 15(A)2 (collectively, the consolidated financial statements). We also have audited the Company’s internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2023, in conformity with U.S. generally accepted accounting principles. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2023 based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

Basis for Opinions

The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s consolidated financial statements and an opinion on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Sufficiency of audit evidence related to the capitalization of property expenditures

As discussed in Note 1 to the consolidated financial statements, expenditures that extend an asset’s useful life or increase its utility are capitalized. The Company has recorded $33,326 million in net book value of properties at December 31, 2023 and has recorded $2,349 million in property additions for the year ended December 31, 2023. Expenditures capitalized include those that are directly related to a capital project and may include materials, labor and other direct costs, in addition to an allocable portion of indirect costs that relate to a capital project. A significant portion of the Company’s annual capital spending relates to self-constructed assets. Costs related to repair and maintenance activities, that in the Company’s judgment, do not extend an asset’s useful life or increase its utility are expensed when such repairs are performed.

We identified the evaluation of the sufficiency of audit evidence related to capitalization of property expenditures as a critical audit matter. Subjective auditor judgment was required in determining procedures and evaluating audit results related to the capitalization of purchased services and compensation due to their usage for both self-constructed assets and repairs and maintenance.

The following are the primary procedures we performed to address the critical audit matter. We applied auditor judgment to determine the nature and extent of procedures to be performed over capitalized property expenditures. We evaluated the design and tested the operating effectiveness of certain internal controls over the Company’s process to capitalize property expenditures, including controls over the determination of whether purchased services and compensation expenditures extend an asset’s useful life or increase its utility. For a sample of property additions expenditures, we inquired and inspected support to evaluate that the expenditure extended an asset’s useful life or increased its utility. We evaluated the sufficiency of audit evidence obtained by assessing the results of the procedures performed, including the appropriateness of the nature of such evidence.

Eastern Ohio Incident

As discussed in Note 17 to the consolidated financial statements, the Company has recognized $464 million of liabilities attributable to the Eastern Ohio Incident (the Incident) as of December 31, 2023. For the year-ended December 31, 2023, the Company has recognized $1,116 million of expenses for costs directly attributable to the Incident, which is presented net of $101 million in insurance recoveries in the Consolidated Statements of Income. As of December 31, 2023, the Company recognized probable and reasonably estimable liabilities for environmental matters and legal proceedings and claims (non-environmental). The Company also disclosed certain legal proceedings and claims (non-environmental) where a loss is reasonably possible, but not probable, or is probable but not reasonably estimable, for which no accrual was established. In addition, as a result of the Incident, the Company disclosed that it is subject to inquiries and investigations by various government authorities and regulatory agencies.

We identified the evaluation of the recognition and measurement of liabilities for environmental matters, legal proceedings and claims (non-environmental) and inquiries and investigations arising from the Incident and the sufficiency of the related disclosures as a critical audit matter. A high degree of subjective auditor judgment was required to evaluate certain judgments and assumptions made by management when assessing the likelihood and magnitude of losses incurred and determining whether reasonable estimates of losses can be made. Specifically, the key judgments and assumptions related to the following:

•the nature and extent of future cleanup and removal activities and the extent and duration of governmental oversight

•the final outcome of the legal proceedings and claims (non-environmental)

•the final outcome of any current or future inquiries and investigations arising from the Incident.

The following are the primary procedures that we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls over the Company’s processes to 1) recognize and measure liabilities associated with environmental matters, legal proceedings and claims (non-environmental), and inquiries and investigations and 2) prepare the related financial statement disclosures. We evaluated the Company's assessment of the likelihood and magnitude of losses being incurred including whether the estimates of losses are reasonably estimable for liabilities associated with the Incident by:

•assessing the estimates of environmental cleanup and remediation liabilities by comparing them to incurred costs

•inquiring of management regarding the expected timeline for both probable and reasonably estimable costs for soil and water disposal and air monitoring activities as well as related governmental oversight

•obtaining a legal confirmation letter from external legal counsel, and inquiring of the Company’s internal and external legal counsel regarding the likelihood and magnitude of losses related to environmental matters, legal proceedings and claims (non-environmental) and inquiries and investigations

•obtaining and inspecting correspondence with government authorities and regulatory agencies for environmental matters, legal proceedings and claims (non-environmental) and inquiries and investigations.
