Forward Looking Statements 17 This presentation contains certain forward-looking information about Citizens Community Bancorp, Inc. and subsidiaries (collectively, “CZWI”) that is intended to be covered by the safe harbor for “forward-looking statements” provided by the Private Securities Litigation Reform Act of 1995. All statements other than statements of historical fact, are forward-looking statements. In some cases, you can identify forward-looking statements by words such as “may,” “hope,” “will,” “should,” “expect,” “plan,” “anticipate,” “intend,” “believe,” “estimate,” “predict,” “potential,” “continue,” “could,” “future” or the negative of those terms or other words of similar meaning. You should carefully read forward-looking statements, including statements that contain these words, because they discuss the future expectations or state other “forward-looking” information about CZWI. Such statements involve inherent risks and uncertainties, many of which are difficult to predict and are generally beyond the control of CZWI. Forward-looking statements speak only as of the date they are made and CZWI assumes no duty to update such statements. In addition to factors previously disclosed in reports filed by CZWI with the Securities and Exchange Commission (“SEC”), additional risks and uncertainties may include, but are not limited to: the possibility that any of the anticipated benefits of the proposed mergers will not be realized or will not be realized within the expected time period; the risk that integration of operations with those of CZWI will be materially delayed or will be more costly or difficult than expected; the inability to complete the mergers due to the failure of shareholder approval to adopt the respective merger agreements; the failure to satisfy other conditions to completion of the mergers, including receipt of required regulatory and other approvals; the failure of the proposed mergers to close for any other reason; the effect of the announcement of the mergers on customer relationships and operating results; the possibility that the mergers may be more expensive to complete than anticipated, including as a result of unexpected factors or events; and general competitive, economic, political and market conditions and fluctuations. As stated previously, additional factors affecting CZWI are discussed in CZWI’s Annual Report on Form 10-K, its Quarterly Reports on Form 10-Q and its Current Reports on Form 8-K, filed with the SEC. Please refer to the SEC’s website at www.sec.gov where you can review those documents.
