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 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.
