Investor Update 1st Quarter 2025 MARCH 2025 Exhibit 99.1

Forward-Looking Statements and Non-GAAP Financial Measures This presentation may contain forward-looking statements regarding M&T Bank Corporation (“M&T”) within the meaning of the Private Securities Litigation Reform Act of 1995 and the rules and regulations of the Securities and Exchange Commission (“SEC”). Any statement that does not describe historical or current facts is a forward-looking statement, including statements based on current expectations, estimates and projections about M&T's business, and management's beliefs and assumptions. Statements regarding the potential effects of events or factors specific to M&T and/or the financial industry as a whole, as well as national and global events generally, on M&T's business, financial condition, liquidity and results of operations may constitute forward-looking statements. Such statements are subject to the risk that the actual effects may differ, possibly materially, from what is reflected in those forward-looking statements due to factors and future developments that are uncertain, unpredictable and in many cases beyond M&T's control. Forward-looking statements are typically identified by words such as "believe," "expect," "anticipate," "intend," "target," "estimate," "continue," or "potential," by future conditional verbs such as "will," "would," "should," "could," or "may," or by variations of such words or by similar expressions. These statements are not guarantees of future performance and involve certain risks, uncertainties and assumptions which are difficult to predict and may cause actual outcomes to differ materially from what is expressed or forecasted. While there can be no assurance that any list of risks and uncertainties is complete, important factors that could cause actual outcomes and results to differ materially from those contemplated by forward-looking statements include the following, without limitation: economic conditions and growth rates, including inflation and market volatility; events and developments in the financial services industry, including industry conditions; changes in interest rates, spreads on earning assets and interest- bearing liabilities, and interest rate sensitivity; prepayment speeds, loan originations, loan concentrations by type and industry, credit losses and market values on loans, collateral securing loans, and other assets; sources of liquidity; levels of client deposits; ability to contain costs and expenses; changes in M&T’s credit ratings; domestic or international political developments and other geopolitical events, including international conflicts and hostilities; changes and trends in the securities markets; common shares outstanding and common stock price volatility; fair value of and number of stock-based compensation awards to be issued in future periods; the impact of changes in market values on trust-related revenues; federal, state or local legislation and/or regulations affecting the financial services industry, or M&T and its subsidiaries individually or collectively, including tax policy; regulatory supervision and oversight, including monetary policy and capital requirements; governmental and public policy changes; political conditions, either nationally or in the states in which M&T and its subsidiaries do business; the outcome of pending and future litigation and governmental proceedings, including tax-related examinations and other matters; changes in accounting policies or procedures as may be required by the Financial Accounting Standards Board, regulatory agencies or legislation; increasing price, product and service competition by competitors, including new entrants; technological developments and changes; the ability to continue to introduce competitive new products and services on a timely, cost-effective basis; the mix of products and services; protection and validity of intellectual property rights; reliance on large customers; technological, implementation and cost/financial risks in large, multi-year contracts; continued availability of financing; financial resources in the amounts, at the times and on the terms required to support M&T and its subsidiaries' future businesses; and material differences in the actual financial results of merger, acquisition, divestment and investment activities compared with M&T's initial expectations, including the full realization of anticipated cost savings and revenue enhancements. These are representative of the factors that could affect the outcome of the forward-looking statements. In addition, as noted, such statements could be affected by general industry and market conditions and growth rates, general economic and political conditions, either nationally or in the states in which M&T and its subsidiaries do business, and other factors. M&T provides further detail regarding these risks and uncertainties in its Form 10-K for the year ended December 31, 2024, including in the Risk Factors section of such report, as well as in other SEC filings. Forward-looking statements speak only as of the date they are made, and M&T assumes no duty and does not undertake to update forward-looking statements. Annualized, pro forma, projected, and estimated numbers are used for illustrative purposes only, are not forecasts and may not reflect actual results. This presentation also contains financial information and performance measures determined by methods other than in accordance with accounting principles generally accepted in the United States ("GAAP"). Management believes investors may find these non-GAAP financial measures useful. These disclosures should not be viewed as a substitute for financial measures determined in accordance with GAAP, nor are they necessarily comparable to non-GAAP performance measures that may be presented by other companies. Please see the Appendix for reconciliation of GAAP with corresponding non-GAAP measures, as indicated in the presentation. 2
