Such statements are subject to numerous assumptions, risks, and uncertainties. Statements that do not describe historical or current facts, including statements about beliefs and expectations, are forward-looking statements. Forward-looking statements may be identified by words such as expect, anticipate, believe, intend, estimate, plan, target, goal, or similar expressions, or future or conditional verbs such as will, may, might, should, would, could, or similar variations. The forward-looking statements are intended to be subject to the safe harbor provided by Section 27A of the Securities Act of 1933, Section 21E of the Securities Exchange Act of 1934, and the Private Securities Litigation Reform Act of 1995. While there is no assurance that any list of risks and uncertainties or risk factors is complete, below are certain factors which could cause actual results to differ materially from those contained or implied in the forward-looking statements: changes in general economic, political, or industry conditions; the magnitude and duration of the COVID-19 pandemic and its impact on the global economy and financial market conditions and our business, results of operations, and financial condition; uncertainty in U.S. fiscal and monetary policy, including the interest rate policies of the Federal Reserve Board; volatility and disruptions in global capital and credit markets; movements in interest rates; reform of LIBOR; competitive pressures on product pricing and services; success, impact, and timing of our business strategies, including market acceptance of any new products or services including those implementing our “Fair Play” banking philosophy; the nature, extent, timing, and results of governmental actions, examinations, reviews, reforms, regulations, and interpretations, including those related to the Dodd- Frank Wall Street Reform and Consumer Protection Act and the Basel III regulatory capital reforms, as well as those involving the OCC, Federal Reserve, FDIC, and CFPB; the occurrence of any event, change or other circumstances that could give rise to the right of one or both of the parties to terminate the merger agreement between Huntington and TCF; the outcome of any legal proceedings that may be instituted against Huntington or TCF; delays in completing the transaction; the failure to obtain necessary regulatory approvals (and the risk that such approvals may result in the imposition of conditions that could adversely affect the combined company or the expected benefits of the transaction); the failure to obtain shareholder approvals or to satisfy any of the other conditions to the transaction on a timely basis or at all; the possibility that the anticipated benefits of the transaction are not realized when expected or at all, including as a result of the impact of, or problems arising from, the integration of the two companies or as a result of the strength of the economy and competitive factors in the areas where Huntington and TCF do business; the possibility that the transaction may be more expensive to complete than anticipated, including as a result of unexpected factors or events; diversion of management’s attention from ongoing business operations and opportunities; potential adverse reactions or changes to business or employee relationships, including those resulting from the announcement or completion of the transaction; the ability to complete the transaction and integration of Huntington and TCF successfully; the dilution caused by Huntington’s issuance of additional shares of its capital stock in connection with the transaction; and other factors that may affect the future results of Huntington and TCF. Additional factors that could cause results to differ materially from those described above can be found in Huntington’s Annual Report on Form 10-K for the year ended December 31, 2020, which is on file with the Securities and Exchange Commission (the “SEC”) and available in the “Investor Relations” section of Huntington’s website, http://www.huntington.com, under the heading “Publications and Filings” and in other documents Huntington files with the SEC, and in TCF’s Annual Report on Form 10-K for the year ended December 31, 2020, which is on file with the SEC and available in the “Investor Relations” section of TCF’s website, http://www.ir.tcfbank.com, under the heading “Financial Information” and in other documents TCF files with the SEC.
