For example, the risk that the proposed transactions do not occur, expected timing and likelihood of completion of the proposed transactions, including the timing, receipt and terms and conditions of any required governmental and regulatory approvals of the proposed acquisition that could reduce anticipated benefits or cause the parties to abandon the transactions, the ability to successfully integrate the businesses, the occurrence of any event, change or other circumstances that could cause the parties to abandon the transactions, risks related to disruption of management time from ongoing business operations due to the proposed transactions, the risk that any announcements relating to the proposed transaction could have adverse effects on the market price of Andeavor Logistics’ common units, WNRL’s common units or Andeavor’s common stock, the risk that the proposed transaction and its announcement could have an adverse effect on the ability of Andeavor Logistics, WNRL and Andeavor to retain customers and retain and hire key personnel and maintain relationships with their suppliers and customers and on their operating results and businesses generally, the risk that problems may arise in successfully integrating the businesses of the companies, which may result in the combined company not operating as effectively and efficiently as expected, the risk that the combined company may be unable to achieve cost-cutting synergies or it may take longer than expected to achieve those synergies, the risk of the amount of any future distribution Andeavor Logistics may pay, and other factors. All such factors are difficult to predict and are beyond Andeavor Logistics’ or Andeavor’s control, including those detailed in Andeavor Logistics’ annual reports on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K that are available on its website at http://andeavorlogistics.com/ and on the SEC’s website at http://www.sec.gov, those detailed in WNRL’s annual reports on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K that are available on WNRL’s website at http://www.wnrl.com and on the SEC website at http://www.sec.gov and those detailed in Andeavor’s website at http://andeavor.com and on the SEC’s website at http://www.sec.gov.
