The absence of these words, however, does not mean that the statements are not forward-looking. These forward-looking statements are based upon current expectations, beliefs, estimates and assumptions that, while considered reasonable as and when made by BBVA and its management, are inherently uncertain. Such forward-looking statements are subject to risks, uncertainties, and other factors that could cause actual results to differ materially from those expressed or implied by such forward-looking statements. For example, the expected timing and likelihood of completion of the transaction, including the timing, receipt and terms and conditions of any required governmental and regulatory approvals of the transaction (including the required authorization or no-opposition by the Spanish National Securities Market Commission, the European Central Bank and certain anti-trust and regulatory authorities), that could reduce anticipated benefits of the transaction or cause BBVA to not be able to complete the transaction, risks related to disruption of management time from ongoing business operations, the risk that matters relating to the transaction could have adverse effects on the market price of the shares of BBVA, the risk that the transaction could have an adverse effect on the ability of BBVA or Banco Sabadell 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 a combined company (if applicable) not operating as effectively and efficiently as expected, the risk that the combined company may be unable to achieve synergies or that it takes longer than expected to achieve those synergies, and other factors. All such factors are difficult to predict and are beyond BBVA’s control, including those detailed in BBVA’s annual reports on Form 20-F and current reports on Form 6-K that are available on the SEC’s website at http://www.sec.gov. BBVA undertakes no obligation to update or revise any forward-looking statements whether as a result of new information, future events or otherwise. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date hereof.
