Forward-looking statements in this report relating to WesBanco's plans, strategies, objectives, expectations, intentions and adequacy of resources, are made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. The information contained in this report should be read in conjunction with WesBanco's Form 10-K for the year ended December 31, 2024 and documents subsequently filed by WesBanco with the Securities and Exchange Commission ("SEC") including WesBanco's Form 10-Q for the quarters ended March 31 and June 30, 2025, which are available at the SEC's website, www.sec.gov or at WesBanco's website, www.WesBanco.com. Investors are cautioned that forward-looking statements, which are not historical fact, involve risks and uncertainties, including those detailed in WesBanco's most recent Annual Report on Form 10-K filed with the SEC under "Risk Factors" in Part I, Item 1A. Such statements are subject to important factors that could cause actual results to differ materially from those contemplated by such statements, including, without limitation, the expected cost savings and any revenue synergies from the merger of WesBanco and Premier may not be fully realized within the expected timeframes; disruption from the merger of WesBanco and Premier may make it more difficult to maintain relationships with clients, associates, or suppliers; the effects of changing regional and national economic conditions, changes in interest rates, spreads on earning assets and interest-bearing liabilities, and associated interest rate sensitivity; sources of liquidity available to WesBanco and its related subsidiary operations; potential future credit losses and the credit risk of commercial, real estate, and consumer loan customers and their borrowing activities; actions of the Federal Reserve Board, the Federal Deposit Insurance Corporation, the Consumer Financial Protection Bureau, the SEC, the Financial Institution Regulatory Authority, the Municipal Securities Rulemaking Board, the Securities Investors Protection Corporation, and other regulatory bodies; potential legislative and federal and state regulatory actions and reform, including, without limitation, the impact of the implementation of the Dodd-Frank Act; adverse decisions of federal and state courts; fraud, scams and schemes of third parties; cyber-security breaches; competitive conditions in the financial services industry; rapidly changing technology affecting financial services; marketability of debt instruments and corresponding impact on fair value adjustments; and/or other external developments materially impacting WesBanco's operational and financial performance. WesBanco does not assume any duty to update forward-looking statements. While forward-looking statements reflect our good-faith beliefs, they are not guarantees of future performance. All forward-looking statements are necessarily only estimates of future results. Accordingly, actual results may differ materially from those expressed in or contemplated by the particular forward-looking statement, and, therefore, you are cautioned not to place undue reliance on such statements. Further, any forward-looking statement speaks only as of the date on which it is made, and we undertake no obligation to update any forward-looking statement to reflect events or circumstances after the date on which the statement is made or to reflect the occurrence of unanticipated events or circumstances, except as required by applicable law. Statements in this presentation with respect to the benefits of the merger between WesBanco and Premier, the parties' plans, obligations, expectations, and intentions, and the statements with respect to accretion, earn back of tangible book value, tangible book value dilution and internal rate of return, constitute forward-looking statements as defined by federal securities laws. Such statements are subject to numerous assumptions, risks, and uncertainties. Actual results could differ materially from those contained or implied by such statements for a variety of factors including: the expected cost savings and any revenue synergies from the merger may not be fully realized within the expected time frames; disruption from the merger may make it more difficult to maintain relationships with clients, associates, or suppliers; changes in economic conditions; movements in interest rates; competitive pressures on product pricing and services; success and timing of other business strategies; the nature, extent, and timing of governmental actions and reforms; extended disruption of vital infrastructure; and other factors described in WesBanco's 2024 Annual Report on Form 10-K and documents subsequently filed by WesBanco with the Securities and Exchange Commission. In addition to the results of operations presented in accordance with Generally Accepted Accounting Principles (GAAP), WesBanco's management uses, and this presentation contains or references, certain non-GAAP financial measures, such as pre-tax pre-provision income, tangible common equity/tangible assets; net income excluding after-tax restructuring and merger-related expenses and excluding after-tax day one provision for credit losses on acquired loans; efficiency ratio; return on average assets; and return on average tangible equity. WesBanco believes these financial measures provide information useful to investors in understanding our operational performance and business and performance trends which facilitate comparisons with the performance of others in the financial services industry. Although WesBanco believes that these non-GAAP financial measures enhance investors' understanding of WesBanco's business and performance, these non-GAAP financial measures should not be considered an alternative to GAAP. The non-GAAP financial measures contained therein should be read in conjunction with the audited financial statements and analysis as presented in the Annual Report on Form 10-K as well as the unaudited financial statements and analyses as presented in the Quarterly Reports on Forms 10-Q for WesBanco and its subsidiaries, as well as other filings that the company has made with the SEC.
