FORWARD-LOOKING STATEMENTS This document contains, and future oral and written statements of QCR Holdings (the “Company”) and its management may contain, forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 with respect to the financial condition, results of opera tions, plans, objectives, future performance and business of the Company. Forward-looking statements, which may be based upon beliefs, expectations and assumptions of the Company’s management and on information currently available to management, are generally identifiable by the use of words such as “believe,” “expect,” “a nticipate,” “predict,” “suggest,” “appear,” “plan,” “intend,” “estimate,” “annualize,” “may,” “will,” “would,” “could,” “should” or other similar expressions. Additiona lly, all statements in this document, including forward-looking statements, speak only as of the date they are made, and the Company undertakes no obligation to update any stat ement in light of new information or future events. A number of factors, many of which are beyond the ability of the Company to control or predict, could cause actual results to d iffer materially from those in its forward-looking statements. These factors include, among others, the following: (i) the strength of the local, state, national and international economies; (ii) the economic impact of any future terrorist threats and attacks, and the response of the United States to any such threats and attacks; (iii) changes in state and federal laws, regulations and governmental policies concerning the Company’s general business; (iv) changes in interest rates and pre payment rates of the Company’s assets; (v) increased competition in the financial services sector and the inability to attract new customers; (vi) changes in techno logy and the ability to develop and maintain secure and reliable electronic systems; (vii) unexpected results of acquisitions, which may include failure to realize the a nticipated benefits of the acquisition and the possibility that the transaction costs may be greater than anticipated; (viii) the loss of key executives or employees; (ix) changes in consumer spending; (x) unexpected outcomes of existing or new litigation involving the Company; and (xi) changes in accounting policies and practices. These r isks and uncertainties should be considered in evaluating forward-looking statements and undue reliance should not be placed on such statements. Additional info rmation concerning the Company and its business, including additional factors that could materially affect the Company’s financial results, is included in t he Company’s filings with the Securities and Exchange Commission (the “SEC”).
