~~Forward-Looking~~Item 9.01 – Financial Statements and Exhibits

This current report on Form 8-K contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements can be identified by words such as “estimate,” “expect,” “will,” and similar references to future periods. Such forward-looking statements include but are not limited to statements regarding the expected closing and potential benefits of the business combination transaction involving the Company and Columbia, including future financial and operating results, the combined company’s plans, objectives, expectations and intentions, and other statements that are not historical facts regarding either company or the proposed combination of the companies. These forward-looking statements are subject to risks and uncertainties, many of which are outside of our control, that may cause actual results or events to differ materially from those projected, including but not limited to the following: risks that the merger transaction will not close when expected or at all because required regulatory, shareholder or other approvals or conditions to closing are delayed or not received or satisfied on a timely basis or at all; risks 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 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 the Company and Columbia operate; uncertainties regarding the ability of Merchants Bank of Commerce and Columbia State Bank to promptly and effectively integrate their businesses; changes in business and operational strategies that may occur between signing and closing; uncertainties regarding the reaction to the transaction of the companies’ respective customers, employees, shareholders, and counterparties; and risks relating to the diversion of management time on merger-related issues. Readers are cautioned not to place undue reliance on the forward-looking statements, which speak only as of the date on which they are made and reflect management’s current estimates, projections, expectations and beliefs. The Company undertakes no obligation to publicly revise or update the forward-looking statements to reflect events or circumstances that arise after the date of this report other than as required by law. For more information, see the risk factors described in the Company’s Annual Report on Form 10-K, Quarterly Reports on Form 10-Q and other filings with the Securities and Exchange Commission (“SEC”).

This report is being filed in respect of the proposed merger transaction involving the Company and Columbia. This communication does not constitute an offer to sell or the solicitation of any vote or approval, nor shall there be any sale of securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction. No offer of securities shall be made except by means of a prospectus meeting the requirements of Section 10 of the Securities Act of 1933, as amended, and otherwise in accordance with applicable law.
