M&T BANK CORP

A provision for credit losses is recorded to adjust the level of the allowance to reflect expected credit losses that are based on economic forecasts as of each reporting date. A provision for credit losses of $135 million was recorded in the third quarter of 2026, compared with $120 million in the second quarter of 2026. A $5 million provision for unfunded credit commitments was recorded in the third quarter of 2026. There was no provision for unfunded credit commitments in the second quarter of 2026. The higher provision for credit losses in the third quarter of 2026 as compared with the second quarter of 2026 reflects loan growth. For the nine months ended September 30, 2026 and 2025, the Company recorded a provision for credit losses of $395 million and $380 million, respectively.

A summary of the Company's net charge-offs by loan type and as an annualized percent of such average loans is presented in the table that follows.

Asset quality

A summary of nonperforming assets and certain past due loan data and credit quality ratios is presented in the accompanying table.

NONPERFORMING ASSET AND PAST DUE LOAN DATA

(a)Primarily residential real estate loans.

Nonaccrual loans at September 30, 2026 increased $90 million from June 30, 2026 reflecting a $47 million rise in commercial and industrial nonaccrual loans and a $41 million rise in commercial real estate nonaccrual loans. Nonaccrual loans declined $214 million from September 30, 2025, primarily driven by a $143 million reduction in commercial and industrial nonaccrual loans and an $89 million reduction in commercial real estate nonaccrual loans. Approximately 48% of nonaccrual commercial and industrial and commercial real estate loans were considered current with respect to their payment status at September 30, 2026.

Government-guaranteed loans designated as accruing loans past due 90 days or more included one-to-four family residential mortgage loans serviced by the Company that were repurchased to reduce associated servicing costs, including a requirement to advance principal and interest payments that had not been received from individual mortgagors. Despite the loans being purchased by the Company, the insurance or guarantee by the applicable government-related entity remains in force. The outstanding principal balances of the repurchased loans that are guaranteed by government-related entities included in accruing loans past due 90 days or more totaled $468 million at September 30, 2026, $489 million at June 30, 2026, $459 million at December 31, 2025 and $333 million at September 30, 2025. Accruing loans past due 90 days or more not guaranteed by government-related entities were loans considered to be with creditworthy borrowers that were in the process of collection or renewal. Additional information about past due and nonaccrual loans is included in note 4 of Notes to Financial Statements.

The Company utilizes a loan grading system to differentiate risk amongst its commercial and industrial loans and commercial real estate loans. Loans with a lower expectation of default are assigned one of ten possible "pass" loan grades while specific loans determined to have an elevated level of credit risk are designated as "criticized." A criticized loan may be designated as "nonaccrual" if the Company no longer expects to collect all amounts owed under the terms of the loan agreement or the loan is delinquent 90 days or more. Targeted reviews are periodically performed over segments of loan portfolios that may be experiencing heightened credit risk due to current or anticipated economic conditions. The intention of such reviews is to identify trends across such portfolios and inform portfolio risk limits and loss mitigation strategies. In the recent quarter, the Company continued to monitor commercial borrowers in certain industry sectors that may be affected by rising interest rates, higher energy and transportation costs and international trade policy changes, such as tariffs, including retail and wholesale trade, manufacturing, food service and packaging companies. The Company has considered the information gathered in such reviews in the assignment of loan grades.

The Company continues to monitor its commercial real estate loan portfolio. The primary source of repayment of these loans is typically tenant lease payments to the investor/borrower. Elevated vacancies impacting some property types have contributed to lower current and anticipated future debt service coverage ratios, which have and may continue to influence the ability of borrowers to make existing loan payments. Lower debt service coverage ratios, reduced commercial real estate values and potentially higher interest rates could also impact the ability of borrowers to refinance their obligations at loan maturity. The Company actively monitors interest rate-sensitive borrowers to reassess loan grades. The LTV ratio is one of many factors considered in assessing overall portfolio risks and loss mitigation strategies for the investor-owned commercial real estate portfolio. In determining the LTV ratio, the Company considers cross-collateralization of all exposures secured by the supporting collateral and the estimated value of such collateral. Subsequent to the origination of commercial real estate loans, updated appraisals are obtained in the normal course of business for renewals, extensions and modifications to commitment levels. As the quality of a loan deteriorates to the point of designating the loan as "criticized nonaccrual," the process of obtaining updated collateral valuation information is usually initiated, unless it is not considered warranted given factors such as the relative size of the loan or the age of the last valuation. In those cases where current appraisals may not yet be available, prior appraisals are utilized with adjustments, as deemed necessary, for estimates of subsequent declines in values as determined by line of business and/or loan workout personnel. Those adjustments are reviewed and assessed for reasonableness by the Company’s credit risk personnel. Accordingly, for real estate collateral securing larger nonaccrual commercial and industrial loans and commercial real estate loans, estimated collateral values are generally based on current estimates of value.

The Company monitors its concentration of commercial real estate lending as a percent of its Tier 1 capital plus its allowable allowance for credit losses, consistent with a metric utilized to differentiate such concentrations amongst regulated financial institutions. This metric, as prescribed in supervisory guidance, excludes loans secured by commercial real estate considered to be owner-occupied, but includes certain other loans, such as loans to real estate investment trusts, that are classified as commercial and industrial loans. The Company's commercial real estate loan concentration approximated 137% of Tier 1 capital plus its allowable allowance for credit losses at September 30, 2026, compared with 134% at June 30, 2026, 124% at December 31, 2025 and 128% at September 30, 2025.

The accompanying tables summarize the outstanding balances, and associated criticized balances, of commercial and industrial loans by industry and commercial real estate loans by property type, respectively, at September 30, 2026 and December 31, 2025.

CRITICIZED COMMERCIAL AND INDUSTRIAL LOANS

CRITICIZED COMMERCIAL REAL ESTATE LOANS

• 66 -

The $203 million reduction in commercial and industrial criticized loans from December 31, 2025 to September 30, 2026 reflects lower criticized loans to motor vehicle and recreational finance dealers, wholesale and health services industries, partially offset by higher criticized loans predominantly to borrowers in the retail and financial and insurance industries. The $958 million decline in commercial real estate criticized loans from December 31, 2025 to September 30, 2026 reflects a $485 million decline in construction and development loans designated as criticized and a $473 million decline in criticized permanent loans secured by most property types. At September 30, 2026, approximately 97% of criticized accrual loans and 48% of criticized nonaccrual loans were considered current with respect to their payment status.

For loans secured by residential real estate the Company’s loss identification and estimation techniques make reference to loan performance and house price data in specific areas of the country where collateral securing those loans is located. For loans secured by residential real estate, including home equity loans and lines of credit, the excess of the loan balance over the net realizable value of the property collateralizing the loan is charged-off when the loan becomes 150 days delinquent. Information about the location of nonaccrual loans secured by residential real estate at September 30, 2026 and December 31, 2025 is presented in the following table.

NONACCRUAL LOANS SECURED BY RESIDENTIAL REAL ESTATE

(a)Includes $598 million and $673 million of limited documentation first lien mortgage loans with nonaccrual loan balances totaling $39 million and $50 million at September 30, 2026 and December 31, 2025, respectively.

Factors that influence the Company’s credit loss experience include overall economic conditions affecting businesses and consumers, generally, but also residential and commercial real estate valuations, in particular, given the size of the Company’s real estate loan portfolios. Commercial real estate valuations can be highly subjective, as they are based upon many assumptions. Such valuations can be significantly affected over relatively short periods of time by changes in business climate, economic conditions, interest rates and, in many cases, the results of operations of businesses and other occupants of the real property. Similarly, residential real estate valuations can be impacted by housing trends, the availability of financing at reasonable interest rates and general economic conditions affecting consumers.

Consumer loans not secured by residential real estate are generally charged-off when the loans are 91 to 180 days past due, depending on whether the loan is collateralized and the status of repossession activities with respect to such collateral. The Company primarily originates recreational finance loans and automobile loans indirectly through dealerships across the U.S. At September 30, 2026, the percent of recreational finance loans and automobile loans with FICO scores of 700 or greater at origination date was 99% and 84%, respectively. A comparative summary of nonaccrual consumer loan balances and the respective percent of outstanding balances of each consumer loan product at September 30, 2026 and December 31, 2025 is presented in the following table.

NONACCRUAL CONSUMER LOANS

Allowance for loan losses

Management determines the allowance for loan losses under accounting guidance that requires estimating the amount of current expected credit losses over the remaining contractual term of the loan portfolio. A description of the methodologies used by the Company to estimate its allowance for loan losses can be found in note 4 of Notes to Financial Statements.

At the time of the Company’s analysis regarding the determination of the allowance for loan losses as of September 30, 2026 uncertainties existed about the impact of inflationary pressures, rising interest rates and potential increases in unemployment on the discretionary income and purchasing power of consumers, which could impact their ability to service existing debt obligations; the volatile nature of global markets and international economic conditions that could impact the U.S. economy, including the effect of international trade policies and recent military conflicts on domestic businesses and consumers; uncertainty related to Federal Reserve positioning of monetary policy and the potential impacts on future economic growth; potential shifts in the labor market resulting from rapid development and deployment of generative and agentic artificial intelligence; downward pressures on commercial real estate values, including office properties, and the impacts on the ability of commercial borrowers to refinance maturing debt obligations at potentially higher interest rates; and the extent to which borrowers may be negatively affected by general economic conditions.

In establishing the allowance for loan losses, the Company estimates losses attributable to specific troubled credits identified through both normal and targeted credit review processes and also estimates losses for other loans with similar risk characteristics on a collective basis, generally through the use of statistically developed credit models, which are required to achieve a satisfactory independent validation by the Company's Model Risk Management Department, or other quantitative methodologies. In determining the allowance for loan losses, the Company may adjust forecasted loss estimates for inherent limitations or biases in the models as well as for other factors that may not be adequately considered in its quantitative methodologies including the impact of portfolio concentrations, imprecision in economic forecasts, geopolitical conditions and other risk factors that influence the loss estimation process. At each of September 30, 2026, June 30, 2026 and December 31, 2025, the Company qualitatively adjusted credit loss estimates for inherent limitations in the ability to assess real-time changes in commercial borrower performance and for environmental influences affecting certain loan portfolios. Qualitative adjustments at September 30, 2026, June 30, 2026 and December 31, 2025, primarily related to portfolio exposures to certain commercial and industrial borrowers, commercial real estate loans and consumer loans, were generally similar. Such qualitative adjustments at March 31, 2026 were elevated reflective of the potential negative impact of global conflicts on economic forecasts utilized at that date.

Forward-looking estimates of certain macroeconomic variables are determined by the M&T Scenario Review Committee, which is comprised of senior management business leaders and economists. The weighted-average of macroeconomic assumptions utilized as of September 30, 2026, June 30, 2026 and December 31, 2025 are presented in the following table and were based on information available at or near the time the Company was preparing its estimate of expected credit losses as of those dates.

ALLOWANCE FOR LOAN LOSSES MACROECONOMIC ASSUMPTIONS

With respect to economic forecasts, the Company assessed the likelihood of alternative economic scenarios during the two-year reasonable and supportable forecast period. Generally, an increase in unemployment rate or a decrease in any of the rate of change in GDP, commercial real estate prices or home prices could have an adverse impact on expected credit losses and may result in an increase to the allowance for loan losses. Forward-looking economic forecasts are subject to inherent imprecision and future outcomes may differ materially from forecasted events. In consideration of such uncertainty, the alternative economic scenarios shown in the following table were considered to estimate the possible impact on modeled credit losses.

ALLOWANCE FOR LOAN LOSSES SENSITIVITIES

These examples are only a few of the numerous possible economic scenarios that could be utilized in assessing the sensitivity of expected credit losses. The estimated impacts on credit losses in such scenarios pertain only to modeled credit losses and do not include consideration of other factors the Company may evaluate when determining its allowance for loan losses. As a result, it is possible that the Company may, at another point in time, reach different conclusions regarding credit loss estimates. The Company’s process for determining the allowance for loan losses undergoes quarterly and periodic evaluations by independent risk management personnel, which among many other considerations, evaluate the reasonableness of management’s methodology and significant assumptions.

A comparative summary of the Company's allowance for loan losses by loan type and the reserve for unfunded credit commitments is presented in the following table.

ALLOWANCE FOR LOAN LOSSES AND RESERVE FOR UNFUNDED CREDIT COMMITMENTS

(a)Included in the allowance for loan losses were reserves allocated as a percent of commercial real estate loans secured by office properties of 3.98% at September 30, 2026, 3.91% at June 30, 2026 and 4.65% at December 31, 2025.

(b)Given the Company’s general position as a secured lender and its practice of charging off loan balances when collection is deemed doubtful, this ratio and changes in the ratio are generally not an indicative measure of the adequacy of the Company’s allowance for loan losses, nor does management rely upon this ratio in assessing the adequacy of the Company’s allowance for loan losses.

(c)Included in Accrued interest and other liabilities in the Consolidated Balance Sheet.

Management has assessed that the allowance for loan losses at September 30, 2026 appropriately reflected expected credit losses in the portfolio as of that date. The lower ratio of the allowance for loan losses as a percent of total loans outstanding at September 30, 2026 and June 30, 2026 as compared with December 31, 2025 reflects lower levels of criticized commercial and industrial loans and commercial real estate loans, partially offset by loan growth. The level of the allowance reflects management’s evaluation of the loan portfolio as of each respective date using the methodology and considering the factors as described herein. Should the various economic forecasts and credit factors considered by management in establishing the allowance for loan losses change and should management’s assessment of losses in the loan portfolio also change, the level of the allowance as a percent of loans could increase or decrease in future periods.
