FORWARD LOOKING STATEMENTS Forward-Looking Statements This communication contains estimates, predictions, opinions, projections and other “forward-looking statements” as that phrase is defined in the Private Securities Litigation Reform Act of 1995. Forward-looking statements include, without limitation, statements relating to the impact Mid Penn expects its proposed merger with Riverview to have on the combined entity’s operations, financial condition, and financial results, and Mid Penn’s expectations about its ability to successfully integrate their respective businesses and the amount of cost savings and overall operational efficiencies Mid Penn expects to realize as a result of the proposed acquisition. The forward-looking statements also include predictions or expectations of future business or financial performance, as well as goals and objectives for future operations, financial and business trends, business prospects, and management’s outlook or expectations for earnings, revenues, expenses, capital levels, liquidity levels, asset quality or other future financial or business performance, strategies or expectations. The words “believe,” “intend,” “expect,” “anticipate,” “strategy,” “plan,” “estimate,” “approximately,” “target,” “project,” “propose,” “possible,” “potential,” “should” and similar expressions, among others, generally identify forward-looking statements. Such forward-looking statements are based on various assumptions (many of which are beyond the control of Mid Penn) and are subject to risks and uncertainties (which change over time) and other factors which could cause actual results to differ materially from those currently anticipated. Such risks and uncertainties include, but are not limited to, the possibility that the proposed acquisition 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; the delay in or failure to close for any other reason; the outcome of any legal proceedings that may be instituted against Mid Penn or Riverview; the occurrence of any event, change or other circumstance that could give rise to the right of one or both parties to terminate the merger agreement providing for the merger; the risk that the businesses of Mid Penn and Riverview will not be integrated successfully; the possibility that the cost savings and any synergies or other anticipated benefits from the proposed acquisition may not be fully realized or may take longer to realize than expected; disruption from the proposed acquisition making it more difficult to maintain relationships with employees, customers or other parties with whom Mid Penn or Riverview have business relationships; diversion of management time on merger- related issues; risks relating to the potential dilutive effect of the shares of Mid Penn common stock to be issued in the proposed transaction; the reaction to the proposed transaction of the companies’ customers, employees and counterparties; uncertainty as to the extent of the duration, scope, and impacts of the COVID-19 pandemic on Mid Penn, Riverview and the proposed transaction; and other factors, many of which are beyond the control of Mid Penn and Riverview. We refer you to the “Risk Factors” section of the Registration Statement and the Joint Proxy/Prospectus, the “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” sections of Mid Penn’s Annual Report on Form 10-K for the year ended December 31, 2020, and any updates to those risk factors set forth in Mid Penn’s Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and other filings, which have been filed by Mid Penn with the SEC and are available on the SEC’s website at www.sec.gov. All forward-looking statements, expressed or implied, included herein are expressly qualified in their entirety by the cautionary statements contained or referred to herein. The actual results or developments anticipated may not be realized or, even if substantially realized, they may not have the expected consequences to or effects on Mid Penn or its respective businesses or operations. We caution readers not to place undue reliance on any such forward-looking statements, which speak only as of the date on which they are made. Neither Mid Penn nor Riverview undertakes any obligation, and specifically declines any obligation, to revise or update any forward-looking statements, whether as a result of new information, future developments or otherwise, except as specifically required by law.
