The first sentence in the first paragraph beginning on page 140 under “The Merger—Opinion of Norfolk Southern’s Financial Advisor—Opinion of BofA Securities, Inc.—Summary of Norfolk Southern Financial Analyses—Selected Precedent Transactions Analysis” is hereby amended and supplemented as follows:

Based on BofA’s review of the TEV/LTM Adjusted EBITDA multiples for the selected transactions and on its professional judgment and experience, BofA applied a TEV/LTM Adjusted EBITDA multiple reference range of 12.00x to 16.00x, to Norfolk Southern’s Adjusted EBITDA for the twelve-month period ended June 30, 2025.

The second and third sentences in the third paragraph beginning on page 140 under “The Merger—Opinion of Norfolk Southern’s Financial Advisor—Opinion of BofA Securities, Inc.—Summary of Norfolk Southern Financial Analyses—Discounted Cash Flow Analysis” are hereby amended and supplemented as follows:

Discounted Cash Flow Analysis. BofA performed a discounted cash flow analysis of Norfolk Southern to calculate the estimated present value of the standalone unlevered, after-tax free cash flows that Norfolk Southern was forecasted to generate during the six-month period ending December 31, 2025 and for the fiscal years 2026 through 2030 based on the Norfolk Southern management unaudited Norfolk Southern projections. Based on BofA’s professional judgment and experience, BofA calculated terminal values for Norfolk Southern by applying terminal multiples of 11.00x to 13.00x to Norfolk Southern’s fiscal year 2030 estimated Adjusted EBITDA. The cash flows and terminal values were then discounted to present value as of June 30, 2025, assuming a mid-year convention for cash flows, using discount rates ranging from 8.50% to 10.00%, which were based on an estimate, based on BofA’s professional judgment and experience, of Norfolk Southern’s weighted average cost of capital.

The second bullet point on page 141 under “The Merger—Opinion of Norfolk Southern’s Financial Advisor—Opinion of BofA Securities, Inc.—Summary of Norfolk Southern Financial Analyses—Other Factors” is hereby amended and supplemented as follows:

Wall Street Analysts Price Targets.

BofA also noted that the median of price targets for Norfolk Southern was $279.00 per share.

The first, second and third sentences in the third full paragraph beginning on page 142 under “The Merger—Opinion of Norfolk Southern’s Financial Advisor—Opinion of BofA Securities, Inc.—Summary of Union Pacific Financial Analyses—Discounted Cash Flow Analysis” are hereby amended and supplemented as follows:

Discounted Cash Flow Analysis. BofA performed a discounted cash flow analysis of Union Pacific to calculate the estimated present value of the standalone unlevered, after-tax free cash flows that Union Pacific was forecasted to generate during the six-month period ending December 31, 2025 and for the fiscal years 2026 through 2031 based on the Norfolk Southern management view of the UP management unaudited projections and unlevered free cash flow, as set forth in the section entitled “Certain Unaudited Prospective Financial Information”. Based on BofA’s professional judgment and experience, BofA calculated terminal values for Union Pacific by applying terminal multiples of 12.00x to 14.00x to Union Pacific’s fiscal year 2031 estimated Adjusted EBITDA. The cash flows and terminal values were then discounted to present value as of June 30, 2025, assuming a mid-year convention for cash flows, using discount rates ranging from 8.50% to 10.00%, which were based on an estimate, based on BofA’s professional judgment and experience, of Union Pacific’s weighted average cost of capital.

BofA also noted that the median of price targets for Union Pacific was $260.00 per share.

The third full paragraph beginning on page 143 under “The Merger—Opinion of Norfolk Southern’s Financial Advisor—Opinion of BofA Securities, Inc.—Summary of Material Pro Forma Financial Analysis—Has/Gets Analysis” is hereby amended and supplemented as follows:

For the aggregate equity value of Norfolk Southern common stock on a standalone basis, BofA used the reference range obtained in its discounted cash flow analysis described above under “Summary of Material Financial Analyses of Norfolk Southern — Discounted Cash Flow Analysis.” BofA then performed the same analysis by calculating the range of implied aggregate equity values allocable to holders of Norfolk Southern common stock on a pro forma basis, giving effect to the mergers, by assuming approximately 27.5% pro forma ownership, based on 225.152 million shares, the number of shares of Union Pacific common stock estimated to be issued to holders of Norfolk Southern common stock in the mergers, utilizing the results of the standalone discounted cash flow analyses for Norfolk Southern and Union Pacific described above under “Summary of Material Financial Analyses of Norfolk Southern – Discounted Cash Flow Analysis” and under “Summary of Material Financial Analyses of Union Pacific – Discounted Cash Flow Analysis,” and taking into account the net present value of the synergies as of June 30, 2025, using a discount rate of 8.5% to 10.0% based on BofA’s professional judgment and experience. For purposes of this analysis, BofA assumed incremental transaction net debt in the amount of $20.4 billion. BofA then compared these implied equity value reference ranges, which were further adjusted by an estimated additional net debt from the mergers and $88.82 per share cash consideration, to the implied equity value reference ranges derived for Norfolk Southern on a standalone basis utilizing the results of the standalone discounted cash flow analysis of Norfolk Southern described above.

These statements relate to future events or future financial performance and involve known and unknown risks, uncertainties, and other factors that may cause Union Pacific’s, Norfolk Southern’s or the combined company’s actual results, levels of activity, performance, or achievements or those of the railroad industry to be materially different from those expressed or implied by any forward-looking statements.

While Union Pacific and Norfolk Southern have based these forward-looking statements on those expectations, assumptions, estimates, beliefs and projections they view as reasonable, such forward-looking statements are only predictions and involve known and unknown risks and uncertainties, many of which involve factors or circumstances that are beyond Union Pacific’s, Norfolk Southern’s or the combined company’s control, including but not limited to, in addition to factors disclosed in Union Pacific’s and Norfolk Southern’s respective filings with the U.S. Securities and Exchange Commission (the “SEC”): the occurrence of any event, change or other circumstance that could give rise to the right of one or both of the parties to terminate the definitive merger agreement between Union Pacific and Norfolk Southern providing for the acquisition of Norfolk Southern by Union Pacific (the “Transaction”); the risk that potential legal proceedings may be instituted against Union Pacific or Norfolk Southern and result in significant costs of defense, indemnification or liability; the possibility that the Transaction does not close when expected or at all because required Surface Transportation Board, shareholder or other approvals and other conditions to closing are not received or satisfied on a timely basis or at all (and the risk that such approvals may result in the imposition of conditions that could adversely affect the combined company or the expected benefits of the Transaction); the risk that the combined company will not realize expected benefits, cost savings, accretion, synergies and/or growth from the Transaction, or that such benefits may take longer to realize or be more costly to achieve than expected, including as a result of changes in, or problems arising from, general economic and market conditions, tariffs, interest and exchange rates, monetary policy, laws and regulations and their enforcement, and the degree of competition in the geographic and business areas in which Union Pacific and Norfolk Southern operate; disruption to the parties’ businesses as a result of the announcement and pendency of the Transaction; the costs associated with the anticipated length of time of the pendency of the Transaction, including the restrictions contained in the definitive merger agreement on the ability of Union Pacific and Norfolk Southern, respectively, to operate their respective businesses outside the ordinary course during the pendency of the Transaction; the diversion of Union Pacific’s and Norfolk Southern’s management’s attention and time from ongoing business operations and opportunities on merger-related matters; the risk that the integration of each party’s operations will be materially delayed or will be more costly or difficult than expected or that the parties are otherwise unable to successfully integrate each party’s businesses into the other’s businesses; the possibility that the Transaction may be more expensive to complete than anticipated, including as a result of unexpected factors or events; reputational risk and potential adverse reactions of Union Pacific’s or Norfolk Southern’s customers, suppliers, employees, labor unions or other business partners, including those resulting from the announcement or completion of the Transaction; the dilution caused by Union Pacific’s issuance of additional shares of its common stock in connection with the consummation of the Transaction; the risk of a downgrade of the credit rating of Union Pacific’s indebtedness, which could give rise to an obligation to redeem existing indebtedness; a

material adverse change in the financial condition of Union Pacific, Norfolk Southern or the combined company; changes in domestic or international economic, political or business conditions, including those impacting the transportation industry (including customers, employees and supply chains); Union Pacific’s, Norfolk Southern’s and the combined company’s ability to successfully implement its respective operational, productivity, and strategic initiatives; a significant adverse event on Union Pacific’s or Norfolk Southern’s network, including, but not limited to, a mainline accident, discharge of hazardous materials, or climate-related or other network outage; the outcome of claims, litigation, governmental proceedings and investigations involving Union Pacific or Norfolk Southern, including, in the case of Norfolk Southern, those with respect to the Eastern Ohio incident; the nature and extent of Norfolk Southern’s environmental remediation obligations with respect to the Eastern Ohio incident; new or additional governmental regulation and/or operational changes resulting from or related to the Eastern Ohio incident; and a cybersecurity incident or other disruption to our technology infrastructure.
