In particular, the statements included in this press release concerning GWBI’s expected performance and strategy, strategies for managing troubled loans, the appropriateness of the ACL, the impact on the business arising from the COVID-19 pandemic, the interest rate environment and the business combination transaction between GWBI and FIBK (the "Transaction") are not historical facts and are forward-looking. Accordingly, the forward-looking statements in this press release are only predictions and involve estimates, known and unknown risks, assumptions and uncertainties that could cause actual results to differ materially from those expressed. All forward-looking statements are necessarily only estimates of future results, and there can be no assurance that actual results will not differ materially from expectations, and, therefore, you are cautioned not to place undue reliance on such statements. In addition to factors previously disclosed in GWBI's and FIBK's reports filed with the U.S. Securities and Exchange Commission (the "SEC") and those identified elsewhere in this press release, the following factors, among others, could cause actual results to differ materially from forward-looking statements or historical performance: 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 GWBI and FIBK; the outcome of any legal proceedings that may be instituted against GWBI or FIBK; the possibility that the Transaction does not close when expected or at all because required regulatory, 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 benefits from the Transaction may not be fully realized or may take longer to realize than expected, including as a result of changes in, or problems arising from, general economic and market conditions, 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 GWBI and FIBK operate; the ability to promptly and effectively integrate the businesses of GWBI and FIBK; 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 GWBI's or FIBK's customers, employees or other business partners, including those resulting from the announcement or completion of the Transaction; the dilution caused by FIBK's issuance of additional shares of its capital stock in connection with the Transaction; the diversion of management's attention and time from ongoing business operations and opportunities on merger-related matters; and the impact of the global COVID-19 pandemic on GWBI's and FIBK's businesses, the ability to complete the Transaction or any of the other foregoing risks. These factors are not necessarily all of the factors that could cause GWBI's, FIBK's or the combined company's actual results, performance, or achievements to differ materially from those expressed in or implied by any of the forward-looking statements. Other unknown or unpredictable factors also could harm GWBI's, FIBK's or the combined company's results.
