M&T BANK CORP

Interest income earned on certain of the Company's assets is exempt from federal income tax. Taxable-equivalent net interest income is a non-GAAP measure that adjusts income earned on a tax-exempt asset to present it on an equivalent basis to interest income earned on a fully taxable asset.

Taxable-equivalent net interest income can be impacted by changes in the composition of the Company's earning assets and interest-bearing liabilities, as discussed herein, as well as changes in interest rates and spreads. The FOMC lowered its federal funds target interest rate by a total of 100 basis points in the last four months of 2024 and by a total of 75 basis points in the last four months of 2025.

Net interest income on a taxable-equivalent basis totaled $6.99 billion in 2025, an increase of $90 million from $6.90 billion in 2024. That increase reflects a 9 basis-point widening of the net interest margin driven by a decrease of 51 basis points in the cost of interest-bearing liabilities, partially offset by a 22 basis-point decline in the yield received on earning assets and a 20 basis-point reduction in the contribution of net interest-free funds. Contributing to lower yields on earning assets and rates paid on interest-bearing liabilities in 2025 was the impact of the aforementioned FOMC interest rate reductions. The yields received on earning assets reflect a reduction of the negative impact from interest rate swap agreements entered into for interest rate risk management purposes on yields received on commercial and industrial and commercial real estate loans. Partially offsetting the overall decline in yields received on earning assets was an increase in yields received on investment securities from the deployment of liquidity into fixed rate investment securities throughout 2024 and 2025 that yielded higher rates than maturing investment securities.

Future changes in market interest rates or spreads, as well as changes in the composition of the Company’s portfolios of earning assets and interest-bearing liabilities that result in changes to spreads, could impact the Company’s net interest income and net interest margin. Future changes in the levels of net interest-free funds and the interest rates used to value such funds could also impact the Company's net interest margin.

The Company's average balance sheets accompanied by the taxable-equivalent interest income and expense and the average rate on the Company's earning assets and interest-bearing liabilities are presented in Table 4 that follows.

The impact of this reduction is primarily included in the "Rate" column.

Interest rate swap agreements

Management assesses the potential impact of future changes in interest rates and spreads by projecting net interest income under several interest rate scenarios. In managing interest rate risk, the Company has utilized interest rate swap agreements to modify the repricing characteristics of certain portions of its earning assets and interest-bearing liabilities. Under the terms of those interest rate swap agreements, the Company generally received payments based on the outstanding notional amount at fixed rates and made payments at variable rates. Periodic settlement amounts arising from these agreements are reflected in either the yields received on earning assets or the rates paid on interest-bearing liabilities. The Company enters into forward-starting interest rate swap agreements predominantly to hedge interest rate exposures expected in future periods. Table 6 summarizes information about interest rate swap agreements entered into for interest rate risk management purposes at December 31, 2025 and 2024.

Lending activities

The Company's lending activities reflect a shift in portfolio composition as it executed various strategies to lessen its relative concentration of commercial real estate loans and to reduce the amount of criticized loans in this category throughout 2024 and 2025. The following table summarizes changes in the components of average loans.

Table 8

AVERAGE LOANS

Average loans grew $1.4 billion from 2024.

•Average commercial and industrial loans grew $2.6 billion reflecting higher average balances of loans to financial and insurance companies and motor vehicle and recreational finance dealers.

•Average commercial real estate loans declined $5.3 billion as the Company executed various strategies to reduce its relative concentration of such loans. Average permanent and construction commercial real estate loans decreased by $3.2 billion and $2.1 billion, respectively.

•Average residential real estate loans grew $945 million reflecting the retention of originated residential mortgage loans and purchases.

•Average consumer loans increased $3.1 billion reflecting recreational finance and automobile average loan growth of $2.2 billion and $638 million, respectively.

Table 9 presents the geographical composition of the Company’s loan portfolio at December 31, 2025.

Table 9

LOANS

Commercial and industrial loans, including leases, represented 46% of total loans at December 31, 2025. Owner-occupied loans secured by real estate included in commercial and industrial loans at December 31, 2025 totaled $11.2 billion. The real estate securing such loans is typically used in the primary business operations of the borrower and is not predominantly dependent on rental income from tenants. The Company also provides financing for leases to commercial customers. Commercial leases included in total commercial and industrial loans at December 31, 2025 aggregated $2.7 billion.

Commercial and industrial loans increased $2.1 billion from December 31, 2024 to December 31, 2025 reflecting growth that spanned several industry types. Loans to customers in the financial and insurance, services and wholesale industries increased $1.3 billion, or 11%, $524 million, or 5%, and $450 million, or 9%, respectively, from the end of 2024.

Table 10 presents information on commercial and industrial loans as of December 31, 2025 relating to borrower industry, geographic area, size and whether the loans are secured by collateral or unsecured.

Table 10

COMMERCIAL AND INDUSTRIAL LOANS

Borrowers in the financial and insurance industry include real estate investment trusts and other specialty lending businesses including fund banking companies and mortgage warehouse lending businesses. Approximately 89% of loans to the financial and insurance industry and 7% of loans to the services industry were designated as loans to NDFIs as prescribed in regulatory guidance applicable to M&T Bank at December 31, 2025. Table 11 presents commercial and industrial commitments and outstanding balances of loans to NDFIs at December 31, 2025.

Table 11

COMMERCIAL AND INDUSTRIAL COMMITMENTS AND LOANS TO NDFIs

(a)Includes real estate investment trust credit facilities, residential mortgage warehouse lines of credit and mortgage loan servicing rights secured financing.

(b)Primarily subscription credit facilities.

(c)Includes credit facilities to wholesale lender finance and leasing companies and business development companies.

(d)Includes credit facilities to consumer lender finance and leasing companies.

Commercial real estate loans originated by the Company are generally secured by investor-owned real estate and include both fixed and variable rate instruments with monthly payments and a balloon payment of the remaining unpaid principal balance at maturity. Maturity dates generally range from three to ten years and, for borrowers in good standing, the terms of such loans may be extended by the customer following maturity at the then-current market rate of interest. Adjustable-rate commercial real estate loans represented approximately 83% of the commercial real estate loan portfolio at the 2025 year end.

Commercial real estate construction and development loans totaled $3.6 billion at December 31, 2025, or 3% of total loans. Approximately 97% of those construction loans had adjustable interest rates. Included in such loans at December 31, 2025 were loans made for various purposes, including the construction of multifamily residential housing, office buildings, health services facilities and other commercial development. In June 2025, the Company sold $661 million of out-of-footprint residential builder and developer loans and recognized a gain on sale of $15 million, which is included in Other revenues from operations in the Consolidated Statement of Income.

M&T Realty Capital, a commercial real estate lending subsidiary of M&T Bank, participates in the DUS program of Fannie Mae, pursuant to which commercial real estate loans are originated in accordance with terms and conditions specified by Fannie Mae and sold. Under this program, loans are sold with partial credit recourse to M&T Realty Capital. The amount of recourse is generally limited to one-third of any credit loss incurred by the purchaser on an individual loan, although in some cases the recourse amount is more or less than one-third of the outstanding principal balance. The Company’s contractual credit recourse associated with sold commercial real estate loans was approximately $4.6 billion at December 31, 2025, compared with $4.2 billion at December 31, 2024. Should Fannie Mae determine that loans originated through its DUS program were not originated or serviced in accordance with the terms and conditions of the program, M&T Realty Capital may be required to repurchase such loans or may incur credit losses that exceed the stated recourse amount of the program.

Table 12 presents commercial real estate loans by type of collateral, geographic area and size of the loans outstanding at December 31, 2025.

Investing activities

The Company's investment securities portfolio is largely comprised of government-issued or guaranteed residential and commercial mortgage-backed securities and U.S. Treasury securities, but also includes municipal and other securities. When purchasing investment securities, the Company considers its liquidity position and its overall interest rate risk profile as well as the adequacy of expected returns relative to risks assumed, including prepayments. The Company may occasionally sell investment securities as a result of movements in interest rates and spreads, changes in liquidity needs, actual or anticipated prepayments, credit risk associated with a particular security, or as a result of restructuring its investment securities portfolio. The amounts of investment securities held by the Company are influenced by such factors as available yield in comparison with alternative investments, demand for loans, which generally yield more than investment securities, ongoing repayments, the levels of deposits, and management of liquidity and balance sheet size and resulting capital ratios. Information about the Company's average investment securities portfolio is presented in the following table.

Table 13

AVERAGE INVESTMENT SECURITIES

(a)Primarily government issued or guaranteed.

The investment securities portfolio averaged $35.8 billion in 2025, up $5.0 billion from 2024. That increase reflects the deployment of liquidity into primarily fixed rate mortgage-backed investment securities designated as available for sale. As a result of the purchases of higher-yielding securities and paydowns and maturities of lower-yielding securities, the weighted-average current yield for total investment securities available for sale increased to 4.64% at December 31, 2025 compared with 4.30% at December 31, 2024, while the weighted-average duration of that portfolio decreased to 2.4 years from 2.6 years at each of those respective dates. The Company routinely adjusts its holdings of capital stock of the FHLB of New York and the FRB of New York based on amounts of outstanding borrowings and available lines of credit with those entities.

The Company regularly reviews its debt investment securities for declines in value below amortized cost that might be indicative of credit-related losses. There were no credit-related losses on debt investment securities recognized in 2025, 2024 and 2023. Additional information about the investment securities portfolio is included in notes 3 and 19 of Notes to Financial Statements.

Other earning assets include interest-bearing deposits at banks and trading account assets. Those other earning assets in the aggregate averaged $18.9 billion in 2025 and $27.3 billion in 2024 and were primarily comprised of deposits held at the FRB of New York. The Company considers such deposits to be an immediate source of funds in its liquidity management processes. In general, the levels of those deposits often fluctuate due to changes in deposits of retail and commercial customers, trust-related deposits and brokered deposits, lending activities and additions to or maturities of investment securities or borrowings.

Funding activities - deposits

The most significant source of funding for the Company is core deposits from its customer base. The Company considers noninterest-bearing deposits, savings and interest-checking deposits and time deposits of $250,000 or less as core deposits. The Company’s domestic banking network is its principal source of core deposits, which generally carry lower interest rates than wholesale funds of comparable maturities. Average core deposits represented 78% of average earning assets in 2025, compared with 77% in 2024. The Company also utilizes brokered deposits as a component of its wholesale funding strategy. Depending on market conditions, including demand by customers and other investors, and the cost of funds available from alternative sources, the Company may change the amount or composition of brokered deposits in the future. Table 14 provides an analysis of changes in the components of average deposits.

Table 14

AVERAGE DEPOSITS

Total average deposits decreased $316 million from 2024.

•Average core deposits grew $1.2 billion due to higher average balances of savings and interest-checking deposits that reflected a shift in customer funds from noninterest-bearing accounts to interest-bearing products. Lower average balances of core time deposits reflected comparatively lower rates paid on those products.

•Average brokered deposits declined $1.2 billion reflecting a decrease in average brokered time deposits of $2.6 billion as those products matured. That decrease was partially offset by an increase in average brokered savings and interest-bearing transaction accounts of $1.5 billion reflecting changes in the Company's wholesale funding strategy.

Table 15 summarizes the components of average total deposits by reportable segment for the years ended December 31, 2025, 2024 and 2023.

Table 15

AVERAGE DEPOSITS BY REPORTABLE SEGMENT

Funding activities - borrowings

Table 16 summarizes the average balances utilized from the Company's short-term and long-term borrowing facilities and note programs.

Table 16

AVERAGE BORROWINGS

The Company uses borrowing capacity from banks, the FHLBs, the FRB of New York and others as sources of funding. Short-term borrowings represent arrangements that at the time they were entered into had a contractual maturity of one year or less. The lower levels of short-term borrowings in 2025 as compared with 2024 reflect the Company's management of liquidity, including reductions in certain short-term wholesale funding sources.

The levels of long-term borrowings reflect the Company's strategies to diversify its wholesale funding sources to provide long-term funding stabilization. Table 17 provides a summary of the Company's issuances, maturities and redemptions of long-term borrowings in 2025.
