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 $130 million and $140 million was recorded in the first quarter of 2025 and fourth quarter of 2024, respectively, compared with $200 million in the year-earlier quarter. The lower provision for credit losses in the most recent two quarters as compared with the first quarter of 2024 reflects improved performance of loans to commercial real estate borrowers, partially offset by commercial and industrial and consumer loan growth and, in the recent quarter, a modest deterioration of macroeconomic forecasts.

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

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)Predominantly government-guaranteed residential real estate loans.

Nonaccrual loans declined $150 million from December 31, 2024 to March 31, 2025 reflecting a $113 million reduction in commercial real estate nonaccrual loans and a $34 million reduction in commercial and industrial nonaccrual loans. As compared with March 31, 2024, the $762 million decline in nonaccrual loans at March 31, 2025 reflects a $576 million reduction in commercial real estate nonaccrual loans and a $202 million reduction in commercial and industrial nonaccrual loans. Approximately 55% of nonaccrual commercial and industrial and commercial real estate loans were considered current with respect to their payment status at March 31, 2025.

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 included in the amounts noted herein that are guaranteed by government-related entities totaled $240 million at March 31, 2025, $224 million at December 31, 2024 and $195 million at March 31, 2024. 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.

Approximately 76% of loans 30 to 89 days past due were less than 60 days delinquent at March 31, 2025, compared with 73% at December 31, 2024. Additional information about past due and nonaccrual loans at March 31, 2025 and December 31, 2024 is included in note 3 of Notes to Financial Statements.

During the normal course of business, the Company modifies loans to maximize recovery efforts. The modifications that the Company grants are typically comprised of maturity extensions, payment deferrals and interest rate reductions, but may also include other modification types. The Company may offer such modified terms to borrowers experiencing financial difficulty. Such modified loans may be considered nonaccrual if the Company does not expect to collect all amounts owed under the terms of the loan agreement. Information about modifications of loans to borrowers experiencing financial difficulty is included in note 3 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

Line of business personnel in different geographic locations with support from and review by the Company’s credit risk personnel review and reassign loan grades based on their detailed knowledge of individual borrowers and their judgment of the impact on such borrowers resulting from changing conditions in their respective regions. The Company’s policy is that, at least annually, updated financial information is obtained from commercial borrowers associated with pass grade loans greater than $1 million and additional analysis performed. On a quarterly basis, the Company’s centralized credit risk department personnel review criticized commercial and industrial loans and commercial real estate loans greater than $5 million to determine the appropriateness of the assigned loan grade, including whether the loan should be reported as accruing or nonaccruing. For criticized nonaccrual loans, additional meetings are held with loan officers and their managers, workout specialists and senior management to discuss each of the relationships. In analyzing criticized loans, borrower-specific information is reviewed, including operating results, future cash flows, recent developments and the borrower’s outlook, and other pertinent data. The timing and extent of potential losses, considering collateral valuation and other factors, and the Company’s potential courses of action are contemplated. Targeted loan 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 began assessing loans to certain not-for-profit borrowers, government contractors and other commercial borrowers that may be impacted by changes to government funding and reductions in the federal workforce. The Company is also monitoring commercial borrowers in certain industry sectors that may be impacted by international trade policy changes, such as tariffs, including retail and wholesale trade, manufacturing and construction companies.

The Company continues to monitor its commercial real estate loan portfolio. Criticized investor-owned commercial real estate loans totaled $5.4 billion or 21% of such loans at March 31, 2025, improved from $6.0 billion or 23% at December 31, 2024. Investor-owned commercial real estate loans comprised 57% of total criticized loans at March 31, 2025, compared with 61% at December 31, 2024. The primary source of repayment of these loans is typically tenant lease payments to the investor/borrower. Elevated vacancies impacting some property types and higher interest rates 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 and reduced commercial real estate values also impact the ability of borrowers, in particular those borrowers with loans secured by office properties, to refinance their obligations at loan maturity. Despite these challenges, the ability of borrowers to service loans secured by certain investor-owned real estate, including health services, hotel and multifamily properties, has improved in recent quarters. 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. The weighted-average LTV ratio for investor-owned commercial real estate loans was approximately 57% at March 31, 2025 and 56% at each of December 31, 2024 and March 31, 2024. Criticized loans secured by investor-owned commercial real estate had a weighted-average LTV ratio of approximately 66%, 63% and 62% at March 31, 2025, December 31, 2024 and March 31, 2024, respectively. 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 appraisals and 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 133% of Tier 1 capital plus its allowable allowance for credit losses at March 31, 2025 and 136% at December 31, 2024, compared with 176% at March 31, 2024. The Company intentionally reduced its relative concentration of investor-owned commercial real estate loans throughout 2024.

The accompanying tables summarize the outstanding balances, and associated criticized balances, of commercial and industrial loans and leases by industry and commercial real estate loans by property type, respectively, at March 31, 2025 and December 31, 2024.

CRITICIZED COMMERCIAL REAL ESTATE LOANS

Loans to motor vehicle and recreational finance dealers and to the services and retail industries contributed to the $151 million increase in commercial and industrial criticized loans from December 31, 2024 to March 31, 2025. The $667 million decline in commercial real estate criticized loans from December 31, 2024 to March 31, 2025 spanned most property types. At March 31, 2025, approximately 96% of criticized accrual loans and 55% 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 residential real estate-related loans, 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. That charge-off is based on recent indications of value from external parties that are generally obtained shortly after a loan becomes nonaccrual. Loans to consumers that file for bankruptcy are generally charged-off to estimated net collateral value shortly after the Company is notified of such filings. Limited documentation first lien mortgage loans represent loans secured by residential real estate that at origination typically included some form of limited borrower documentation requirements as compared with more traditional loans. The Company no longer originates limited documentation loans. With respect to junior lien loans, to the extent known by the Company, if a related senior lien loan would be on nonaccrual status because of payment delinquency, even if such senior lien loan was not owned by the Company, the junior lien loan or line that is owned by the Company is placed on nonaccrual status. In monitoring the credit quality of its home equity portfolio for purposes of determining the allowance for credit losses, the Company reviews delinquency and nonaccrual information and considers recent charge-off experience. When evaluating individual home equity loans and lines of credit for charge-off and for purposes of determining the allowance for credit losses, the Company considers the required repayment of any first lien positions related to collateral property. Information about the location of nonaccrual loans secured by residential real estate at March 31, 2025 is presented in the following table.

NONACCRUAL LOANS SECURED BY RESIDENTIAL REAL ESTATE

(a)Includes $760 million of limited documentation first lien mortgage loans with nonaccrual loan balances totaling $56 million.

(b)Includes Delaware, Maryland, New Jersey, Pennsylvania, Virginia, West Virginia and the District of Columbia.

(c)Includes Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island and Vermont.

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. A comparative summary of consumer loans in nonaccrual status by product is presented in the following table.

Allowance for credit losses

Management determines the allowance for credit losses under accounting guidance that requires estimating the amount of current expected credit losses over the remaining contractual term of the loan and lease portfolio. A description of the methodologies used by the Company to estimate its allowance for credit losses can be found in note 3 of Notes to Financial Statements.

In establishing the allowance for credit 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 and leases with similar risk characteristics on a collective basis. For purposes of determining the level of the allowance for credit losses, the Company evaluates its loan and lease portfolio by type. At the time of the Company’s analysis regarding the determination of the allowance for credit losses as of March 31, 2025 concerns existed about the impact of potential inflationary pressures and increases in unemployment on the discretionary income and purchasing power of consumers, which could impact their ability to service existing debt obligations; slower economic growth in future quarters; the volatile nature of global markets and international economic conditions that could impact the U.S. economy, including the effect of international trade policies on domestic businesses and consumers; uncertainty related to Federal Reserve positioning of monetary policy; potential changes to federal taxation rates; downward pressures on commercial real estate values, especially in the office sector; the persistence of elevated interest rates impacting the ability of commercial borrowers to refinance maturing debt obligations; and the extent to which borrowers may be negatively affected by general economic conditions.

The Company generally estimates current expected credit losses on loans with similar risk characteristics on a collective basis. To estimate expected losses, the Company utilizes statistically developed models to project principal balances over the remaining contractual lives of the loan portfolios and determine estimated credit losses through a reasonable and supportable forecast period. The Company’s approach for estimating current expected credit losses for loans and leases at each reporting date included utilizing macroeconomic assumptions to project losses over a two-year reasonable and supportable forecast period. Subsequent to the forecast period, the Company reverted to longer-term historical loss experience, over a period of one year, to estimate expected credit losses over the remaining contractual life. In determining the allowance for credit 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 March 31, 2025 and December 31, 2024, 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 March 31, 2025, primarily related to portfolio exposures to certain commercial and industrial borrowers, commercial real estate loans and recreational finance consumer loans, were largely unchanged from December 31, 2024.

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 March 31, 2025 and December 31, 2024 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 CREDIT LOSSES MACROECONOMIC ASSUMPTIONS

• 57 -

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 credit 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 following alternative economic scenarios were considered to estimate the possible impact on modeled credit losses.

ALLOWANCE FOR CREDIT 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 credit 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 credit 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. Further information about the Company’s methodology to estimate expected credit losses is included in note 3 of Notes to Financial Statements.

Management has assessed that the allowance for credit losses at March 31, 2025 appropriately reflected expected credit losses inherent in the portfolio as of that date. The allowance for credit losses totaled $2.2 billion at each of March 31, 2025 and December 31, 2024. As a percent of loans and leases outstanding, the allowance was 1.63% at March 31, 2025 and 1.61% at December 31, 2024. The increase in the allowance for credit losses as a percent of loans and leases outstanding since December 31, 2024 reflects a modest deterioration in macroeconomic forecasts. Included in the allocation of the allowance for credit losses were reserves for loans secured by office properties of 4.37% at March 31, 2025 and 4.70% at December 31, 2024. The level of the allowance reflects management’s evaluation of the loan and lease portfolio 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 credit 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. The reported level of the allowance for credit losses reflects management’s evaluation of the loan and lease portfolio as of each respective date.

The ratio of the allowance for credit losses to total nonaccrual loans at March 31, 2025 and December 31, 2024 was 143% and 129%, respectively. Given the Company’s general position as a secured lender and its practice of charging off loan balances when collection is deemed doubtful, that ratio and changes in the ratio are generally not an indicative measure of the adequacy of the Company’s allowance for credit losses, nor does management rely upon that ratio in assessing the adequacy of the Company’s allowance for credit losses.
