Exhibit 99.1

M&T BANK CORPORATION ANNOUNCES THIRD QUARTER RESULTS

BUFFALO, NEW YORK -- M&T Bank Corporation (“M&T”) (NYSE: MTB) today reported its results of operations for the quarter ended September 30, 2020.

GAAP Results of Operations.  Diluted earnings per common share measured in accordance with generally accepted accounting principles (“GAAP”) were $2.75 in the third quarter of 2020, compared with $3.47 in the year-earlier quarter and $1.74 in the second quarter of 2020. GAAP-basis net income was $372 million in the recent quarter, $480 million in the third quarter of 2019 and $241 million in the second 2020 quarter. GAAP-basis net income in the third quarter of 2020 expressed as an annualized rate of return on average assets and average common shareholders' equity was 1.06% and 9.53%, respectively, compared with 1.58% and 12.73%, respectively, in the similar 2019 period and .71% and 6.13%, respectively, in the second quarter of 2020.  

Darren J. King, Executive Vice President and Chief Financial Officer, commented on M&T’s third quarter results, “Our results for the recent quarter reflect an uptick in economic activity across large portions of our customer base that contributed significantly to higher transaction levels and robust mortgage banking revenues. Coupled with well-controlled expenses that were in line with our expectations and prudent loan loss provisioning, M&T remains well-positioned as we enter the final quarter of 2020.”

For the first nine months of 2020 and 2019, diluted earnings per common share were $6.42 and $10.16, respectively. GAAP-basis net income for the nine-month period ended September 30, 2020 totaled

$882 million, compared with $1.44 billion in the year-earlier period. Expressed as an annualized rate of return on average assets and average common shareholders’ equity, GAAP-basis net income during the nine-month period ended September 30, 2020 was .89% and 7.57%, respectively, and was 1.62% and 12.85%, respectively, in the similar 2019 period.

Supplemental Reporting of Non-GAAP Results of Operations.  M&T consistently provides supplemental reporting of its results on a “net operating” or “tangible” basis, from which M&T excludes the after-tax effect of amortization of core deposit and other intangible assets (and the related goodwill and core deposit and other intangible asset balances, net of applicable deferred tax amounts) and expenses associated with merging acquired operations into M&T (when incurred), since such items are considered by management to be “nonoperating” in nature.  The amounts of such “nonoperating” expenses are presented in the tables that accompany this release.  Although “net operating income” as defined by M&T is not a GAAP measure, M&T's management believes that this information helps investors understand the effect of acquisition activity in reported results.

Diluted net operating earnings per common share were $2.77 in the third quarter of 2020, $3.50 in the third quarter of 2019 and $1.76 in the second quarter of 2020.  Net operating income in 2020’s third quarter was $375 million, compared with $484 million in the third quarter of 2019 and $244 million in the second quarter of 2020. Expressed as an annualized rate of return on average tangible assets and average tangible common shareholders' equity, net operating income in the recent quarter was 1.10% and 13.94%, respectively, 1.66% and 18.85%, respectively, in the corresponding quarter of 2019 and .74% and 9.04%, respectively, in the second quarter of 2020.

Diluted net operating earnings per common share during the first nine months of 2020 and 2019 were $6.49 and $10.24, respectively. Net operating income during the nine-month period ended September 30, 2020 was $891 million, compared with $1.45 billion in the similar 2019 period. Net operating income expressed as an annualized rate of return on average tangible assets and average tangible common shareholders’ equity was .93% and 11.15%, respectively, in the initial nine months of 2020 and was 1.70% and 19.07%, respectively, in the year-earlier period.

Taxable-equivalent Net Interest Income.  Net interest income expressed on a taxable-equivalent basis totaled $947 million in the recent quarter, compared with $1.04 billion in the third quarter of 2019. That decline resulted from an 83 basis point narrowing of the net interest margin, to 2.95% in the third quarter of 2020 from 3.78% in the year-earlier quarter, that was partially offset by the impact of a $19.1 billion or 18% increase in average earning assets to $127.7 billion in the recent quarter from $108.6 billion in the third quarter of 2019. In the second quarter of 2020, taxable-equivalent net interest income was $961 million, the net interest margin was 3.13% and average earning assets were $123.5 billion. Included in average earning assets in the third and second quarters of 2020 were $6.5 billion and $4.8 billion, respectively, of balances associated with the Paycheck Protection Program (“PPP”) loans originated by M&T during 2020.  As compared with the third

M&T BANK CORPORATION

quarter of 2019, the recent quarter’s narrowing of the net interest margin resulted largely from lower yields on loans and deposits held at the Federal Reserve Bank of New York, while the rise in average earning assets reflected higher balances of those same asset types.  The narrowing of the net interest margin from the second quarter to the third quarter of 2020 resulted from lower yields on loans and investment securities and the impact of a $4.4 billion rise in average balances of short-term earning assets, which earn a significantly lower yield than loans and investment securities.

Provision for Credit Losses/Asset Quality.  The provision for credit losses totaled $150 million in the third quarter of 2020, up from $45 million in the year-earlier quarter, but down from $325 million in 2020’s second quarter. The significantly higher level of the provision in the 2020 quarters reflected projections of expected credit losses under the provisions of new accounting guidance that became effective on January 1, 2020. Those projections included estimates of the impact of the COVID-19 pandemic. Prior to 2020, the provision for credit losses reflected incurred losses only. Net loan charge-offs were $30 million during the recent quarter, compared with $36 million in the similar quarter of 2019 and $71 million in the second quarter of 2020. Expressed as an annualized percentage of average loans outstanding, net charge-offs were .12% and .16% during the three-month periods ended September 30, 2020 and 2019, respectively, and .29% in the second quarter of 2020.

Loans classified as nonaccrual totaled $1.24 billion or 1.26% of total loans outstanding at September 30, 2020, compared with $1.16 billion or 1.18% of total loans at June 30, 2020. Nonaccrual loans outstanding at September 30, 2019 were $1.01 billion or 1.12% of total loans. The adoption of the new accounting guidance previously mentioned resulted in an increase in nonaccrual loans on January 1, 2020 of $171 million. Assets taken in foreclosure of defaulted loans were $50 million at September 30, 2020, compared with $80 million and $67 million at September 30, 2019 and June 30, 2020, respectively.

Allowance for Credit Losses.  M&T regularly performs detailed analyses of individual borrowers and portfolios for purposes of assessing the adequacy of the allowance for credit losses. As a result of those analyses, the allowance for credit losses totaled $1.76 billion or 1.79% of loans outstanding at September 30, 2020, compared with $1.04 billion or 1.16% at September 30, 2019, $1.64 billion or 1.68% at June 30, 2020 and $1.18 billion or 1.30% as of January 1, 2020 following adoption of the current expected credit loss accounting rules. The adoption of the amended accounting guidance resulted in an increase to the allowance of $132 million on January 1, 2020. The allowance at September 30, 2020 and June 30, 2020 represented 1.91% and 1.79%, respectively, of total loans on those dates, excluding outstanding balances of PPP loans.

Noninterest Income and Expense.  Noninterest income was $521 million in the recent quarter, $528 million in the year-earlier quarter and $487 million in the second quarter of 2020. As compared with the third quarter of 2019, the recent quarter’s higher residential mortgage banking revenues and trust income were more than offset by lower service charges on deposit accounts and trading account and foreign exchange gains. The recent quarter’s improvement as compared with the second quarter of 2020 predominantly reflects higher service charges on deposit accounts, residential mortgage banking revenues and merchant discount and credit card fees.

Noninterest expense totaled $827 million in the third quarter of 2020, compared with $878 million in the corresponding quarter of 2019 and $807 million in the second quarter of 2020.  Excluding expenses considered to be nonoperating in nature, such as amortization of core deposit and other intangible assets, noninterest operating expenses were $823 million in the recent quarter, $873 million in the third quarter of 2019 and $803 million in 2020’s second quarter. Contributing to the decreased level of noninterest expenses in the recent quarter as compared with the year-earlier quarter were lower costs for professional and outside services, advertising and marketing, and travel and entertainment. Additionally, the third quarter of 2019 included a $14 million addition to the valuation allowance for capitalized mortgage servicing rights, reflecting the impact of

lower interest rates at that time on the valuation of such servicing rights. There was no similar increase to the valuation allowance in the recent quarter. As compared with the second 2020 quarter, higher costs for salaries and employee benefits in the recent quarter, reflective of improving business activity and one additional day, were partially offset by the impact of a $10 million addition to the valuation allowance for capitalized mortgage servicing rights recognized in the second quarter of 2020.

The efficiency ratio, or noninterest operating expenses divided by the sum of taxable-equivalent net interest income and noninterest income (exclusive of gains and losses from bank investment securities), measures the relationship of operating expenses to revenues.  M&T's efficiency ratio was 56.2% in the third quarter of 2020, 56.0% in the year-earlier quarter and 55.7% in the second quarter of 2020.

Balance Sheet.  M&T had total assets of $138.6 billion at September 30, 2020, compared with $125.5 billion and $139.5 billion at September 30, 2019 and June 30, 2020, respectively. Loans and leases, net of unearned discount, were $98.4 billion at September 30, 2020, up from $89.8 billion at September 30, 2019 and $97.8 billion at June 30, 2020. The increase in total loans and leases at the recent quarter-end as compared with the third quarter of 2019 was driven largely by growth in commercial loans of $4.7 billion and commercial real estate loans of $2.6 billion. The commercial loan growth reflects loans originated as part of the PPP, which totaled $6.5 billion at September 30, 2020. Total deposits rose to $115.2 billion at the recent quarter-end, compared with $95.1 billion at September 30, 2019 and $115.0 billion at June 30, 2020. The higher levels of deposits at the two most recent quarter-ends as compared with September 30, 2019 reflect both increased commercial and consumer deposits, as well as higher deposits associated with residential mortgage servicing activities.

Total shareholders' equity was $16.1 billion, or 11.61% of total assets at September 30, 2020, compared with $15.8 billion, or 12.57% at September 30, 2019 and $15.9 billion, or 11.43% at June 30, 2020. Common shareholders' equity was $14.9 billion, or $115.75 per share, at September 30, 2020, up from $14.5 billion, or $109.84 per share, a year-earlier and $14.7 billion, or $114.54 per share, at June 30, 2020. Tangible equity per

M&T BANK CORPORATION

common share was $79.85 at September 30, 2020, $74.93 at September 30, 2019 and $78.62 at June 30, 2020. In the calculation of tangible equity per common share, common shareholders' equity is reduced by the carrying values of goodwill and core deposit and other intangible assets, net of applicable deferred tax balances.  M&T estimates that the ratio of Common Equity Tier 1 to risk-weighted assets under regulatory capital rules was approximately 9.81% at September 30, 2020, up from 9.50% three months earlier.
