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 was $1.72 billion in the second quarter of 2025, compared with $1.71 billion in the first quarter of 2025. That increase reflects an additional calendar day of earnings and a comparatively favorable impact of interest rate swap agreements used for hedging purposes in the recent quarter, partially offset by $20 million of lower taxable-equivalent interest income resulting from an alignment of amortization periods for certain municipal bonds obtained from the acquisition of People's United. The net interest margin, or taxable-equivalent net interest income expressed as an annualized percentage of average earning assets, was 3.62% in the recent quarter, down from 3.66% in the first quarter of 2025.

Taxable-equivalent net interest income in the first six months of 2025 was $3.43 billion, compared with $3.42 billion in the corresponding 2024 period. That increase reflects an 8 basis-point widening of the net interest margin driven by a decrease of 55 basis points in the cost of interest-bearing liabilities, partially offset by a 27 basis-point decline in the yield received on earning assets. Contributing to the decrease in yields received on earning assets and rates paid on interest-bearing liabilities in the first half of 2025 as compared with the first half of 2024 was a reduction by the FOMC of its federal funds target interest rate by a total of 1.00% in the last four months of 2024. Partially offsetting the decline in yields received on earning assets was an increase in the yields received on investment securities from the deployment of liquidity into fixed rate investment securities from early 2024 through June 2025 that yielded higher rates than maturing investment securities. The Company continues to adjust its funding sources in consideration of the competitive landscape for customer deposits and maintenance of its liquidity profile. The Company's average balance sheets accompanied by the annualized taxable-equivalent interest income and expense and the average rate on the Company's earning assets and interest-bearing liabilities are presented as follows.

Lending activities

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

AVERAGE LOANS

Average loans totaled $135.4 billion in the second quarter of 2025, up $563 million from the first quarter of 2025.

•Average commercial and industrial loans were $61.0 billion in the recent quarter, relatively unchanged from the first quarter of 2025.

•Commercial real estate loans averaged $25.3 billion in the second quarter of 2025, down $926 million from the first quarter of 2025, reflecting decreases of $247 million and $679 million of average permanent and construction commercial real estate loans, respectively. Contributing to the decline were payoffs and the sale of $661 million of out-of-footprint residential builder and developer loans.

•Average residential real estate loans increased $508 million in the recent quarter as compared with the first quarter of 2025, reflecting a higher retention of originated residential mortgage loans and purchases.

•Average consumer loans in the second quarter of 2025 increased $1.0 billion from the first quarter of 2025 to $25.4 billion reflecting higher average balances of recreational finance loans and automobile loans of $611 million and $329 million, respectively.

Investing activities

The Company's investment securities portfolio is largely comprised of government-issued or guaranteed commercial and residential 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.

AVERAGE INVESTMENT SECURITIES

(a)Primarily government issued or guaranteed.

The investment securities portfolio averaged $35.3 billion in the second quarter of 2025, up $855 million from the first quarter of 2025. That increase reflects the deployment of liquidity into primarily fixed rate investment securities, including purchases of fixed rate agency mortgage-backed securities and U.S. Treasury securities of $1.2 billion and $638 million, respectively, in the recent quarter, into the Company's available-for-sale investment securities portfolio. In the first six months of 2025 and 2024, investment securities averaged $34.9 billion and $29.1 billion, respectively. The Company purchased fixed rate agency mortgage-backed securities and U.S. Treasury securities of $8.5 billion and $3.1 billion, respectively, since June 30, 2024. As a result of the elevated interest rate environment throughout much of 2024 and the maturities of lower-yielding securities, the weighted-average current yield for total investment securities available for sale increased to 4.50% at June 30, 2025 and 4.42% at March 31, 2025, compared with 3.83% at June 30, 2024. The weighted-average duration of the available-for-sale investment securities portfolio was 2.6 years at June 30, 2025, compared with 2.5 years and 2.1 years at March 31, 2025 and June 30, 2024, respectively. There were no significant sales of investment securities during the three and six months ended June 30, 2025. In 2024, the Company sold $181 million of non-agency investment securities from its available-for-sale portfolio and its remaining equity investments in Fannie Mae and Freddie Mac preferred securities. 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. In light of such reviews, there were no credit-related losses on debt investment securities recognized in each of the six months ended June 30, 2025 and June 30, 2024. A further discussion of fair values of investment securities is included herein under the heading "Capital." Additional information about the investment securities portfolio is included in notes 3 and 13 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 $19.8 billion in each of the three-month periods ended June 30, 2025 and March 31, 2025, and $19.8 billion in the six months ended June 30, 2025, compared with $30.1 billion in the six months ended June 30, 2024. The amounts of other earning assets at those respective dates were primarily comprised of deposits held at the FRB of New York. In general, the levels of those deposits often fluctuate due to changes in deposits of retail and commercial customers, trust-related deposits, brokered deposits 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. 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 branch network is its principal source of core deposits, which generally carry lower interest rates than wholesale funds of comparable maturities. Average core deposits represented 79% and 78% of average earning assets for the quarters ended June 30, 2025 and March 31, 2025, respectively, and 78% and 76% for the six months ended June 30, 2025 and 2024, respectively. The Company also includes 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. The following table provides an analysis of changes in the components of average deposits.

AVERAGE DEPOSITS

Total deposits averaged $163.4 billion in the recent quarter, up from $161.2 billion in the first quarter of 2025.

•Average core deposits increased $2.4 billion from the first quarter of 2025 reflecting higher average savings and interest-checking deposits and customer time deposits.

•The decrease in average brokered deposits from the first quarter of 2025 reflected maturities of brokered time deposits.

In the first six months of 2025, total average deposits decreased $1.5 billion from the corresponding 2024 period.

•Average core deposits grew $1.0 billion due to higher average balances of savings and interest-checking deposits reflecting growth and a shift in customer funds from noninterest-bearing accounts to interest-bearing products. Lower average balances of core time deposits in the first half of 2025 reflected comparatively lower rates paid on those products.

•Average brokered deposits declined $2.0 billion as compared with the first half of 2024. Average brokered time deposits decreased $3.8 billion in the first half of 2025, reflecting maturities. The Company's brokered savings and interest-bearing transaction accounts increased to $10.0 billion in the six months ended June 30, 2025 from $8.1 billion in the similar 2024 period, reflecting changes in the Company's wholesale funding strategy.

Funding activities - borrowings

The following table summarizes the average balances utilized from the Company's short-term and long-term borrowing facilities and note programs.

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. Average short-term borrowings in the second quarter of 2025 as compared with the first quarter of 2025 were modestly higher. The lower levels of average short-term borrowings for the six months ended June 30, 2025 as compared with the similar 2024 period reflect the Company's management of liquidity, including reductions in 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 and prepare for proposed regulations enumerating certain long-term debt requirements as described in Part I, Item 1, "Resolution Planning and Resolution-Related Requirements" of M&T's 2024 Annual Report. The following table provides a summary of the Company's issuances, maturities and redemptions of long-term borrowings for the three-month and six-month periods ended June 30, 2025.

LONG-TERM BORROWING ISSUANCES, MATURITIES AND REDEMPTIONS

(a)At par value.

(b)Excludes paydowns of asset-backed notes.

Additional information regarding borrowings is provided in notes 5 and 12 of Notes to Financial Statements.

Net interest margin

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. Net interest spread, or the difference between the yield on earning assets and the rate paid on interest-bearing liabilities, was 2.80% in the recent quarter, down from 2.82% in the first quarter of 2025. The decrease in the net interest spread reflects an increase in the rates paid on the Company's interest-bearing liabilities and a decline in the yield on earning assets. The yield on earning assets declined 1 basis point in the second quarter of 2025 to 5.51%, reflecting lower taxable-equivalent interest income on investment securities resulting from an alignment of amortization periods for certain municipal bonds obtained from the acquisition of People's United. That decrease was partially offset by a rise in yields received on average loans. The rate paid on interest-bearing liabilities was 2.71%, up 1 basis point from the first quarter of 2025. Increases in the rates paid on the Company's average non-brokered interest-bearing deposits and average borrowings were partially offset by a reduction in the cost of brokered deposits. For the first six months of 2025 and 2024, net interest spread was 2.80% and 2.52%, respectively. Reductions to the rates paid on interest-bearing liabilities outpaced lower yields received on earning assets. Contributing to those decreases in the first half of 2025 as compared with the corresponding 2024 period was a reduction by the FOMC of its federal funds target interest rate by a total of 1.00% in the last four months of 2024.

Net interest-free funds consist largely of noninterest-bearing demand deposits and other liabilities and shareholders’ equity, partially offset by bank owned life insurance and non-earning assets, including goodwill and core deposit and other intangible assets. Net interest-free funds averaged $58.0 billion in the second quarter of 2025, down from $59.2 billion in the first quarter of 2025. Net interest-free funds averaged $58.6 billion and $61.6 billion for the six months ended June 30, 2025 and 2024, respectively. Noninterest-bearing deposits averaged $45.2 billion and $45.4 billion in the second and first quarters of 2025, respectively, and $45.3 billion and $48.2 billion in the first half of 2025 and 2024, respectively. The decline in average noninterest-bearing deposits in the first six months of 2025 as compared with the similar 2024 period reflects a shift in deposits to interest-bearing accounts in an elevated interest rate environment. The contribution of net interest-free funds to net interest margin was .82% in the second quarter of 2025, compared with .84% in the first quarter of 2025. For the first six months of 2025 and 2024, the contribution of net interest-free funds was .84% and 1.04%, respectively. The decreased contribution of net interest-free funds to net interest margin in the first six months of 2025 as compared with the first six months of 2024 reflects lower rates paid, in the most recent six months, on interest-bearing liabilities used to value net interest-free funds.

Reflecting the changes to the net interest spread and the contribution of net interest-free funds as described herein, the Company’s net interest margin was 3.62% in the second quarter of 2025, compared with 3.66% in the first quarter of 2025. During the first six months of 2025 and 2024, the net interest margin was 3.64% and 3.56%, respectively. 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.

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 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. The following table summarizes information about interest rate swap agreements entered into for interest rate risk management purposes at June 30, 2025 and December 31, 2024.
