Forward-Looking Statements
This Current Report on Form 8-K contains forward-looking statements as defined in the Private Securities Litigation Reform Act of 1995. In general, forward-looking statements usually use words such as “may,” “believe,” “expect,” “anticipate,” “intend,” “should,” “plan,” “estimate,” “predict,” “continue” and “potential” or the negative of these terms or other comparable terminology, including statements related to the expected timing of the closing of the proposed merger with Grand River, the expected returns and other benefits of the proposed merger to shareholders, expected improvement in operating efficiency resulting from the proposed merger, estimated expense reductions resulting from the transactions and the timing of achievement of such reductions, the expected impact on and timing of the recovery of the impact on tangible book value, and the expected effect of the proposed merger on Isabella’s capital ratios. Forward-looking statements represent management’s beliefs, based upon information available at the time the statements are made, with regard to the matters addressed; they are not guarantees of future performance. Forward-looking statements are subject to numerous assumptions, risks and uncertainties that change over time and could cause actual results or financial condition to differ materially from those expressed in or implied by such statements.
Factors that could cause or contribute to such differences include, but are not limited to (1) the risk that the cost savings and any revenue synergies from the proposed merger may not be realized or take longer than anticipated to be realized, (2) disruption from the proposed merger with customers, suppliers, employees or other business partners, (3) the occurrence of any event, change or other circumstances that could give rise to the termination of the merger agreement, (4) the risk of successful integration of Grand River’s business into Isabella, (5) the amount of the costs, fees, expenses and charges related to the proposed merger, (6) reputational risk and the reaction of each of the companies’ customers, suppliers, employees or other business partners to the merger, (7) the failure of the closing conditions in the merger agreement to be satisfied, or any unexpected delay in closing of the proposed merger, (8) the risk that the integration of Grand River’s operations into the operations of Isabella will be materially delayed or will be more costly or difficult than expected, (9) the possibility that the proposed merger may be more expensive to complete than anticipated, including as a result of unexpected factors or events, (10) the dilution caused by Isabella’s issuance of additional shares of its common stock in the merger transaction, and (11) general competitive, economic, political and market conditions. Other relevant risk factors may be detailed from time to time in Isabella’s press releases and filings with the Securities and Exchange Commission. Consequently, no forward-looking statement can be guaranteed. Neither Isabella nor Grand River undertakes any obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. For any forward-looking statements made in this communication or any related documents, Isabella and Grand River claim protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995.
