M&T BANK CORP

Market risk is the risk of loss from adverse changes in the market prices and/or interest rates of the Company’s financial instruments. A primary market risk the Company is exposed to is interest rate risk. Interest rate risk arises from the Company’s core banking activities of lending and deposit-taking, because assets and liabilities reprice at different times and by different amounts as interest rates change. As a result, net interest income earned by the Company is subject to the effects of changing interest rates. The Company measures interest rate risk by calculating the variability of net interest income in future periods under various interest rate scenarios using projected balances for earning assets, interest-bearing liabilities and derivatives used to hedge interest rate risk. Management’s philosophy toward interest rate risk management is to limit the variability of net interest income.

The Company’s Executive ALCO Committee monitors the sensitivity of the Company’s net interest income to changes in interest rates with the aid of a computer model that forecasts net interest income under different interest rate scenarios. In modeling changing interest rates, the Company considers different yield curve shapes that contemplate both parallel (that is, when interest rates at each point of the yield curve change by the same magnitude) and non-parallel (that is, allowing interest rates at points on the yield curve to change by different amounts) shifts in the yield curve. The Company also contemplates instantaneous and gradual shifts in the yield curve over the scenario time horizon. In utilizing the model, market-implied forward interest rates over the subsequent twelve months are generally used to determine a base interest rate scenario for the net interest income simulation. That calculated base net interest income is then compared with the income calculated under the varying interest rate scenarios. The model considers the impact of ongoing lending and deposit-gathering activities, as well as interrelationships in the magnitude and timing of the repricing of financial instruments, including the effect of changing interest rates on expected prepayments and maturities.

Management has taken actions to mitigate exposure to interest rate risk through the use of on- and off-balance sheet financial instruments and intends to do so in the future. Possible actions include, but are not limited to, changes in the pricing of loan and deposit products, modifying the composition of earning assets and interest-bearing liabilities, and adding to, modifying or terminating existing interest rate swap agreements or other financial instruments used for interest rate risk management purposes. At December 31, 2025, the aggregate notional amount of interest rate swap agreements entered into for interest rate risk management purposes that were currently in effect was $19.6 billion. In addition, the Company has entered into $11.5 billion of forward-starting interest rate swap agreements designated for hedging purposes. Information about interest rate swap agreements entered into for interest rate risk management purposes is included herein under the heading "Taxable-equivalent Net Interest Income" and in note 17 of Notes to Financial Statements.

The accompanying table as of December 31, 2025 and December 31, 2024 displays the estimated impact on net interest income in the base scenarios described above resulting from changes in market interest rates. The scenarios presented in the table below assume a gradual and parallel change in interest rates across repricing categories during the first modeling year.

SENSITIVITY OF NET INTEREST INCOME TO CHANGES IN INTEREST RATES

The Company utilized many assumptions to calculate the impact that changes in interest rates may have on net interest income. The more significant of those assumptions included the rate of prepayments of mortgage-related assets, cash flows from derivative and other financial instruments, loan and deposit volumes, mix and pricing, and deposit maturities. Variations in amounts presented since December 31, 2024 reflect changes in the composition of the Company's earning assets and interest-bearing liabilities, as well as the level of market-implied forward interest rates and hedging actions taken by the Company. M&T's cumulative upward deposit pricing beta, which is the change in deposit pricing in response to a change in market interest rates, approximated 55% amidst a rising interest rate environment from the first quarter of 2022 through the second quarter of 2024. Reflecting the first cuts of the federal funds target interest rate since March 2020, the FOMC decreased that rate by 100 basis points during the last four months of 2024 and by an additional 75 basis points during the last four months of 2025. M&T's cumulative downward deposit pricing beta beginning in the third quarter of 2024 through December 31, 2025 approximated 51%. The assumptions used in interest rate sensitivity modeling are inherently uncertain and, as a result, the Company cannot precisely predict the impact of changes in interest rates on net interest income. Actual results may differ significantly from those presented due to the timing, magnitude and frequency of changes in interest rates and changes in market conditions and interest rate differentials (spreads) between maturity/repricing categories, as well as any actions, such as those previously described, which management may take to counter such changes.

Management also uses an EVE model to supplement the modeling technique described above and provide a long-term interest rate risk metric. EVE is a point-in-time analysis of the economic sensitivity of existing assets, liabilities and off-balance sheet positions that incorporates all cash flows over their estimated remaining lives. The EVE reflects the present value of cash flows from existing assets, liabilities and off-balance sheet financial instruments, but does not incorporate any assumptions for future originations, renewals or issuances. Management measures the impact of changes in market values due to interest rates under a number of scenarios, including immediate shifts of the yield curve. The percentage impact to the EVE resulting from a 100 basis-point increase and a 100 basis-point decrease in market interest rates was -5.1% and 2.2%, respectively, as of December 31, 2025, and -5.1% and 2.5%, respectively, at December 31, 2024.

In addition to the effect of interest rates, changes in fair value of the Company’s financial instruments can also result from a lack of trading activity for similar instruments in the financial markets. Information about the fair valuation of financial instruments is presented in note 19 of Notes to Financial Statements.

The Company enters into interest rate and foreign exchange contracts to meet the financial needs of customers that it includes in its consolidated financial statements as other non-hedging derivatives within other assets and other liabilities. Financial instruments utilized for such activities consist predominantly of interest rate swap agreements and forward and futures contracts related to foreign currencies. The Company generally mitigates the interest rate and foreign currency risk associated with customer activities by entering into offsetting positions with third parties that are also included in other assets and other liabilities. The fair values of non-hedging derivative positions associated with interest rate contracts and foreign currency and other option and futures contracts are presented in note 17 of Notes to Financial Statements. As with any non-government guaranteed financial instrument, the Company is exposed to credit risk associated with counterparties to its non-hedging derivative activities. Although the notional amounts of these contracts are not recorded in the Consolidated Balance Sheet, the unsettled fair values of such financial instruments are recorded in the Consolidated Balance Sheet. The fair values of such non-hedging derivative assets and liabilities recognized in the Consolidated Balance Sheet were $190 million and $409 million, respectively, at December 31, 2025 and $206 million and $787 million, respectively, at December 31, 2024. The amounts recorded in the Consolidated Balance Sheet associated with the Company's non-hedging derivative activities at December 31, 2025 and 2024 primarily reflect changes in values associated with interest rate swap agreements entered into with commercial customers and financial institutions that are not subject to periodic variation margin settlement payments.

Trading account assets were $97 million at December 31, 2025 and $101 million at December 31, 2024 and were comprised of mutual funds and other assets related to certain deferred compensation plans and non-qualified supplemental retirement and other benefit plans that were assumed by the Company in various acquisitions. Changes in the fair values of such assets are recorded as Trading account and other non-hedging derivative gains in the Consolidated Statement of

Income. Changes in the valuation of the related liabilities, which are included in Accrued interest and other liabilities in the Consolidated Balance Sheet, are recognized in Other costs of operations in the Consolidated Statement of Income.

Given the Company’s policies and positions, management believes that the potential loss exposure to the Company resulting from market risk associated with trading account and other non-hedging derivative activities was not material at December 31, 2025, however, as previously noted, the Company is exposed to credit risk associated with counterparties to such activities. Information about the Company’s use of derivative financial instruments is included in note 17 of Notes to Financial Statements.
