Ladies and Gentlemen:

M&T Bank Corporation, a New York corporation (the “Company”), confirms its agreement with RBC Capital Markets, LLC, Barclays Capital Inc. and M&T Securities, Inc., as representatives (in such capacity, the “Representatives”) of the underwriters named in Schedule A hereto (collectively, the “Underwriters”, which term shall also include any underwriter substituted as hereinafter provided in Section 10 hereof), with respect to the sale by the Company and the purchase by the Underwriters, acting severally and not jointly, of $500,000,000 aggregate principal amount of the Company’s 4.553% Fixed Rate/Floating Rate Senior Notes due 2028 (the “Securities”). To the extent there are no additional parties listed on Schedule A other than the Representatives, the term Representatives as used herein shall mean the Underwriters, and the terms shall be construed as equivalents. The terms Representatives and Underwriters shall mean either the singular or plural as the context requires.

The Securities will be issued pursuant to an Indenture, dated as of May 24, 2007 (the “Base Indenture”), by and between the Company and The Bank of New York Mellon, successor to The Bank of New York, as trustee (the “Trustee”), as supplemented by the Third Supplemental Indenture thereto, to be dated as of August 16, 2022, by and between the Company and the Trustee (the “Supplemental Indenture” and, together with the Base Indenture, the “Indenture”).

The Company understands that the Underwriters propose to make a public offering of the Securities as soon as the Representatives deem advisable after this Agreement has been executed and delivered.

The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) an automatic shelf registration statement on Form S-3ASR (File No. 333-259888) covering the offer and sale of certain securities of the Company, including the Securities, from time to time under the Securities Act of 1933, as amended (the “1933 Act”), and the rules and regulations promulgated thereunder (the “1933 Act Regulations”). Such registration statement has become effective under the 1933 Act. Such registration statement, as of any time, means such registration statement as amended by any post-effective amendments thereto at such time, including the exhibits and any schedules thereto at such time, the documents incorporated or deemed to be incorporated by reference therein at such time pursuant to Item 12 of Form S-3 under the 1933 Act and the documents otherwise deemed to be a part thereof as of such time pursuant to Rule 430B of the 1933 Act Regulations (“Rule 430B”), and is referred to herein as the “Registration Statement;” provided, however, that the “Registration Statement” without reference to a time means such registration statement as amended by any post-effective amendments thereto as of the time of the first contract of sale for the Securities, which time shall be considered the “new effective date” of the Registration Statement with respect to the Securities within the meaning of Rule 430B(f)(2), including the exhibits and schedules thereto as of such time, the documents incorporated or deemed to be incorporated by reference therein at such time pursuant to Item 12 of Form S-3 under the 1933 Act and the documents otherwise deemed to be a part thereof as of such time pursuant to the Rule 430B. Each preliminary prospectus supplement and the base prospectus used in connection with the offering of the Securities, including the documents incorporated or deemed to be incorporated by reference therein pursuant to Item 12 of Form S-3 under the 1933 Act immediately prior to the Applicable Time (as defined below), are collectively referred to herein as a “preliminary prospectus.” Promptly after execution and delivery of this Agreement, the Company will prepare and file a final prospectus supplement relating to the Securities in accordance with the provisions of Rule 424(b) of the 1933 Act Regulations (“Rule 424(b)”). The final prospectus supplement and the base prospectus, in the form first furnished to the Underwriters for use in connection with the offering and sale of the Securities, including the documents incorporated or deemed to be incorporated by reference therein pursuant to Item 12 of Form S-3 under the 1933 Act immediately prior to the Applicable Time, are collectively referred to herein as the “Prospectus.” For purposes of this Agreement, all references to the Registration Statement, any preliminary prospectus or the Prospectus or any amendment or supplement thereto shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system (or any successor system) (“EDGAR”).

The execution, delivery and performance of this Agreement, the Indenture and the Securities and the consummation of the transactions contemplated in this Agreement and in the Registration Statement, the General Disclosure Package and the Prospectus and compliance by the Company with its obligations under this Agreement, the Indenture and the Securities have been duly authorized by the Company by all requisite action and do not and will not, whether with or without the giving of notice or passage of time or both, conflict with or constitute a breach of, or default or Repayment Event (as defined below) under, or result in the creation or imposition of any lien, charge or encumbrance upon any properties, assets or operations of the Company or any of its subsidiaries pursuant to, the Agreements and Instruments (except for such conflicts, breaches, defaults or Repayment Events or liens, charges or encumbrances that would not, singly or in the aggregate, result in a Material Adverse Effect), nor will such action result in any violation of the provisions of the charter, by-laws or similar organizational document of the Company or any of its subsidiaries or any law, statute, rule, regulation, judgment, order, writ or decree of any Governmental Entity (except, in the case of any such violations of any law, statute, rule, regulation, judgment, order, writ or decree of any Governmental Entity, for such violations as would not, singly or in the aggregate, result in a Material Adverse Effect). As used herein, a “Repayment Event” means any event or condition which gives the holder of any note, debenture or other financing instrument (or any person acting on such holder’s behalf) the right to require the repurchase, redemption or repayment of all or a portion of the related financing by the Company or any of its subsidiaries.

No labor dispute with the employees of the Company or any of its subsidiaries exists or, to the knowledge of the Company, is imminent, and the Company is not aware of any existing or imminent labor disturbance by the employees of any of its or any subsidiary’s principal suppliers, manufacturers, customers or contractors, which would, singly or in the aggregate, result in a Material Adverse Effect.

(t) Absence of Proceedings. Except as described in the Registration Statement, the General Disclosure Package and the Prospectus, there is no action, suit, proceeding, inquiry or investigation before or brought by any Governmental Entity now pending, or, to the knowledge of the Company, threatened, against or affecting the Company or any of its subsidiaries, which is, singly or in the aggregate, reasonably likely to result in a Material Adverse Effect, or which is reasonably likely to materially and adversely affect their respective

10

properties, assets or operations, or the consummation of the transactions contemplated in this Agreement, or the performance by the Company of its obligations under this Agreement, the Indenture and the Securities. The aggregate of all pending legal or governmental proceedings to which the Company or any of its subsidiaries are a party or of which any of their respective properties, assets or operations are the subject which are not described in the Registration Statement, the General Disclosure Package and the Prospectus, including ordinary routine litigation incidental to the business, would not, singly or in the aggregate, result in a Material Adverse Effect.

(u) Accuracy of Contracts; Exhibits. All descriptions in the Registration Statement, the General Disclosure Package and the Prospectus of contracts and other documents to which the Company or any of its subsidiaries are a party are accurate in all material respects. There are no contracts, instruments or other documents which are required to be described in the Registration Statement, any preliminary prospectus or the Prospectus or to be filed as exhibits to the Registration Statement which have not been so described and filed as required.

(v) Absence of Further Requirements. No filing with, or authorization, approval, consent, license, order, registration, qualification or decree of, any Governmental Entity is necessary or required for the Company to enter into, or perform its obligations under, this Agreement, the Indenture and the Securities or the consummation of the transactions contemplated in this Agreement, except such as have been already obtained or as may be required under the 1933 Act, the 1933 Act Regulations, the securities laws of any state or non-U.S. jurisdiction or the rules of Financial Industry Regulatory Authority, Inc. (“FINRA”).

(w) Possession of Licenses and Permits. The Company and its subsidiaries possess such permits, licenses, approvals, consents and other authorizations (collectively, “Governmental Licenses”) issued by the appropriate Governmental Entities necessary to conduct the business now operated by them, except where the failure so to possess would not, singly or in the aggregate, result in a Material Adverse Effect. The Company and its subsidiaries are in compliance with the terms and conditions of all Governmental Licenses, except where the failure so to comply would not, singly or in the aggregate, result in a Material Adverse Effect. All of the Governmental Licenses are valid and in full force and effect, except when the invalidity of such Governmental Licenses or the failure of such Governmental Licenses to be in full force and effect would not, singly or in the aggregate, result in a Material Adverse Effect. Neither the Company nor any of its subsidiaries has received any notice of proceedings relating to the revocation or modification of any Governmental Licenses which, if the subject of an unfavorable decision, ruling or finding, could, singly or in the aggregate, result in a Material Adverse Effect.

SECTION 6. Indemnification.

(a) The Company agrees to indemnify and hold harmless each Underwriter, its affiliates (as such term is defined in Rule 501(b) of the 1933 Act Regulations (each, an “Affiliate”)), selling agents, partners, officers and directors, each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act as follows:

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), including any information deemed to be a part thereof pursuant to Rule 430B, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact included (A) in any preliminary prospectus, any Issuer Free Writing Prospectus, the General Disclosure Package or the Prospectus (or any amendment or supplement thereto) or (B) in any materials or information provided to

23

investors by, or with the approval of, the Company in connection with the marketing of the offering of the Securities (“Marketing Materials”), including any roadshow or investor presentations made to investors by the Company (whether in person or electronically), or the omission or alleged omission in any preliminary prospectus, any Issuer Free Writing Prospectus, the General Disclosure Package or the Prospectus (or any amendment or supplement thereto) or in any Marketing Materials of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any Governmental Entity, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 6(d) hereof) any such settlement is effected with the written consent of the Company;

(iii) against any and all expense whatsoever, as incurred (including the reasonable fees and disbursements of counsel chosen by the Representatives), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any Governmental Entity, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in the Registration Statement (or any amendment thereto), including any information deemed to be a part thereof pursuant to Rule 430B, or in the General Disclosure Package or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with the Underwriter Information.

(b) Indemnification of Company, Directors and Officers. Each Underwriter severally agrees to indemnify and hold harmless the Company, its directors, its officers, each of its officers who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act against any and all loss, liability, claim, damage and expense described in the indemnity contained in Section 6(a) hereof, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto), including any information deemed to be a part thereof pursuant to Rule 430B, or in the General Disclosure Package or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with the Underwriter Information.

(c) Actions against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall

24

not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in and, to the extent that it shall elect, jointly with all other indemnifying parties similarly notified, by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that a conflict may arise between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of such indemnifying party’s election so to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 6 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the immediately preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel (together with local counsel), approved by the indemnifying party (or by the Representatives in the case of Sections 6(b) and 7 hereof), representing the indemnified parties who are parties to such action) or (ii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action, in each of which cases the fees and expenses of counsel shall be at the expense of the indemnifying party. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any Governmental Entity, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 6 or Section 7 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d) Settlement without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request (other than those fees and expenses that are being contested in good faith) prior to the date of such settlement.

25

SECTION 7. Contribution. If the indemnification provided for in Section 6 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company, on the one hand, and the Underwriters, on the other hand, in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company, on the one hand, and the total underwriting discount received by the Underwriters, on the other hand, in each case as set forth on the cover of the Prospectus, bear to the aggregate public offering price of the Securities as set forth on the cover of the Prospectus.

The relative fault of the Company, on the one hand, and the Underwriters, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters, as the case may be, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 7. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any Governmental Entity, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the underwriting discount received by such Underwriter in connection with the Securities underwritten by it and distributed to the public.

No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

26

For purposes of this Section 7, each person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act and each Underwriter’s Affiliates, selling agents, partners, officers and directors shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company. The Underwriters’ respective obligations to contribute pursuant to this Section 7 are several in proportion to the respective principal amount of Securities set forth opposite their respective names in Schedule A hereto and not joint.

SECTION 8. Representations, Warranties and Agreements to Survive. All representations, warranties and agreements contained in this Agreement, or in certificates of officers of the Company or any of its subsidiaries submitted pursuant hereto, shall remain operative and in full force and effect regardless of (i) any investigation made by or on behalf of any Underwriter or its Affiliates, partners, officers, directors and or selling agents, any person controlling any Underwriter or the Company’s officers or directors or any person controlling the Company and (ii) delivery of and payment for the Securities.

SECTION 9. Termination of Agreement.

(a) Termination. The Representatives may terminate this Agreement, by notice to the Company, at any time at or prior to the Closing Time, (i) if there has been, in the judgment of the Representatives, since the time of execution of this Agreement or since the respective dates as of which information is given in the Registration Statement, the General Disclosure Package or the Prospectus, any Material Adverse Change, or (ii) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Representatives, impracticable or inadvisable to proceed with the completion of the offering of the Securities or to enforce contracts for the sale of the Securities, or (iii) if trading in any securities of the Company has been suspended or materially limited by the Commission or the New York Stock Exchange, or (iv) if trading generally on the New York Stock Exchange or in the Nasdaq Global Market has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by order of the Commission, FINRA or any other Governmental Entity, or (v) if a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States or with respect to Clearstream or Euroclear systems in Europe, or (vi) if a banking moratorium has been declared by either Federal or New York authorities.

(b) Liabilities. If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections 1, 6, 7, 8, 15, 16 and 17 shall survive such termination and remain in full force and effect.

27

SECTION 10. Default by One or More of the Underwriters. If one or more of the Underwriters shall fail at the Closing Time to purchase the Securities which it or they are obligated to purchase under this Agreement (the “Defaulted Notes”), the Representatives shall have the right, within 36 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Notes in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representatives shall not have completed such arrangements within such 36-hour period, then:

(i) if the aggregate principal amount of Defaulted Notes does not exceed 10% of the aggregate principal amount of Securities to be purchased on such date, each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters, or

(ii) if the aggregate principal amount of Defaulted Notes exceeds 10% of the aggregate principal amount of Securities to be purchased on such date, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter.

No action taken pursuant to this Section 10 shall relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement, the Representatives shall have the right to postpone the Closing Time for a period not exceeding seven days in order to effect any required changes in the Registration Statement, the General Disclosure Package or the Prospectus or in any other documents or arrangements. As used herein, the term “Underwriter” includes any person substituted for an Underwriter under this Section 10.

SECTION 11. Recognition of the U.S. Special Resolution Regimes

(a) In the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

(b) In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

WHEREAS, the Company wishes to make certain changes relating to covenant breaches, events of default, remedies, permitted transfers and certain other matters, with the amendments applying only to Securities of a series created at the time, or after the, time this Third Supplemental Indenture is executed and not applying to, or modifying the rights of Holders of any Securities of a series created prior to the execution of this Third Supplemental Indenture;

SECTION 3 GENERAL TERMS AND CONDITIONS OF THE NOTES.

3.01 Designation and Principal Amount. There is hereby authorized a series of Securities designated as the 4.553% Fixed Rate/Floating Rate Senior Notes due 2028. The Trustee shall authenticate and deliver the Notes for original issue on the date hereof in the aggregate principal amount of $500,000,000.

3.02 Maturity. The Notes shall mature and the principal thereof shall be due and payable, together with all accrued and unpaid interest thereon, on August 16, 2028 (the “Maturity Date”).

3.03 Form and Denomination. The Notes and the Trustee’s certificate of authentication for such Notes shall be substantially in the form of Exhibit A, which is hereby incorporated in and expressly made part of this Third Supplemental Indenture. The Notes shall be issued as fully registered global notes which shall be deposited with a custodian for the Depositary, which Depositary initially shall be DTC and registered in the name of Cede & Co, as nominee of DTC, in denominations of $2,000 or any amount in excess thereof that is an integral multiple of $1,000. Beneficial interests in such Global Securities shall be held in denominations of $2,000 or any amount in excess thereof which is an integral multiple of $1,000.

3.04 Business Day Convention. If any Fixed Rate Interest Payment Date (as defined below) on or before August 16, 2027, any redemption date or the Maturity Date falls on a day that is not a Business Day, then payment of any interest, principal or premium payable on such date will be postponed to the next succeeding Business Day, with the same force and effect as if made on the date such payment was due, and no interest or other payment will accrue as a result of such delay. If any Floating Rate Interest Payment Date after August 16, 2027, other than any Floating Rate Interest Payment Date that is a redemption date or the Maturity Date, falls on a day that is not a Business Day, then payment of any interest payable on such date will be postponed to the next succeeding Business Day, except that, if the next succeeding Business Day falls in the next calendar month, then such interest payment will be advanced to the immediately preceding day that is a Business Day and, in each case, the related Interest Periods also will be adjusted for such non-Business Days. The term “Interest Payment Date” means a Fixed Rate Interest Payment Date or a Floating Rate Interest Payment Date. The term “Interest Period” means the period from and including August 16, 2022, or from and including the most recent Interest Payment Date (whether or not such Interest Payment Date was a Business Day) for which interest has been paid or provided for with respect to the Notes to, but excluding, the next Interest Payment Date, redemption date or the Maturity Date, as the case may be.

18

3.05 Fixed Rate Period. During the period from, and including, August 16, 2022, to, but excluding, August 16, 2027 (the “Fixed Rate Period”), the Notes will bear interest at the rate of 4.553% per annum. Such interest will be payable semi-annually, in arrears, on February 16 and August 16 of each year, beginning on February 16, 2023 and ending on August 16, 2027 (each such date a “Fixed Rate Interest Payment Date”). During the Fixed Rate Period, interest will be computed on the basis of a 360-day year consisting of twelve 30-day months.

3.06 Floating Rate Period. During the period from, and including, August 16, 2027, to, but excluding, the Maturity Date (the “Floating Rate Period”), the Notes will bear interest at a floating rate per annum equal to Compounded SOFR (as defined below) plus 1.780%, as determined in arrears by the Calculation Agent (as defined below) in the manner described below. Such interest will be payable quarterly, in arrears, on November 16, 2027, February 16, 2028, and May 16, 2028 and at the Maturity Date (each such date a “Floating Rate Interest Payment Date”). Compounded SOFR for each Interest Period will be calculated by the Calculation Agent in accordance with the formula set forth in Section 3.07 with respect to the Observation Period (as defined below) relating to such Interest Period.

During the Floating Rate Period, interest will be computed on the basis of the actual number of days in each Interest Period (or any other relevant period) and a 360-day year. The amount of accrued interest payable on the Notes for each Interest Period will be computed by multiplying (i) the outstanding principal amount of the Notes by (ii) the product of (a) the interest rate for the relevant Interest Period multiplied by (b) the quotient of the actual number of calendar days in the applicable Interest Period (or any other relevant period) divided by 360. The interest rate on the Notes will in no event be higher than the maximum rate permitted by New York law as the same may be modified by United States law of general application and will in no event be lower than zero.

The Calculation Agent will determine Compounded SOFR, the interest rate and accrued interest for each Interest Period in arrears as soon as reasonably practicable on or after the Interest Payment Determination Date (as defined below) for such Interest Period and prior to the relevant Interest Payment Date and will notify the Company (if the Company is not the Calculation Agent) of the Compounded SOFR, such interest rate and accrued interest for each Interest Period as soon as reasonably practicable after such determination, but in any event by the Business Day immediately prior to the Interest Payment Date. At the request of a Holder of the Notes, the Company will provide the Compounded SOFR, the interest rate and the amount of interest accrued with respect to any Interest Period, after the Compounded SOFR, such interest rate and accrued interest have been determined. The Calculation Agent’s determination of any interest rate, and its calculation of interest payments for any Interest Period during the Floating Rate Period, will be maintained on file at the Calculation Agent’s principal offices and will be provided in writing to the Trustee. All determinations made by the Calculation Agent shall, in the absence of manifest error, be conclusive for all purposes and binding on the Company and the Holders of the Notes.

19

3.07 Compounded SOFR. With respect to any Interest Period during the Floating Rate Period, “Compounded SOFR” will be determined by the Calculation Agent in accordance with the following formula (and the resulting percentage will be rounded, if necessary, to the nearest one hundred-thousandth of a percentage point, with 0.00000005, or 0.000005%, being rounded upwards):

where:

“SOFR Index_Start” means, for periods other than the initial Interest Period in the Floating Rate Period, the SOFR Index value on the preceding Interest Payment Determination Date, and, for the initial Interest Period in the Floating Rate Period, the SOFR Index value on the date that is two U.S. Government Securities Business Days before the first day of such initial Interest Period;

“SOFR Index_End” means the SOFR Index value on the Interest Payment Determination Date relating to the applicable Interest Payment Date (or in the final Interest Period, relating to the Maturity Date, or, in the case of the redemption of the Notes, relating to the applicable redemption date); and

“d” is the number of calendar days in the relevant Observation Period.

For purposes of determining Compounded SOFR,

“Interest Payment Determination Date” means the date two U.S. Government Securities Business Days before each Interest Payment Date (or in the final Interest Period, preceding the Maturity Date, or in the case of the redemption of the Notes, preceding the applicable redemption date, as the case may be).

“Observation Period” means, in respect of each Interest Period in the Floating Rate Period, the period from, and including, the date two U.S. Government Securities Business Days preceding the first date in such Interest Period to, but excluding, the date two U.S. Government Securities Business Days preceding the Interest Payment Date for such Interest Period (or in the final Interest Period, preceding the Maturity Date or, in the case of the redemption of the Notes, preceding the applicable redemption date).

“SOFR” means the daily secured overnight financing rate as provided by the SOFR Administrator on the SOFR Administrator’s Website.

“SOFR Administrator” means the Federal Reserve Bank of New York (the “FRBNY”) (or a successor administrator of SOFR).

20

“SOFR Administrator’s Website” means the website of the SOFR Administrator, www.newyorkfed.org as of the date of this Third Supplemental Indenture, or any successor source.

“SOFR Index” means, with respect to any U.S. Government Securities Business Day:

“U.S. Government Securities Business Day” means any day except for a Saturday, a Sunday or a day on which the Securities Industry and Financial Markets Association or any successor organization recommends that the fixed income departments of its members be closed for the entire day for purposes of trading in U.S. government securities.

Notwithstanding anything to the contrary in the Indenture or the Notes, if the Company or its designee determines on or prior to the relevant Reference Time (as defined below) that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to determining SOFR, then the benchmark replacement provisions set forth in Section 3.09 will thereafter apply to all determinations of the rate of interest payable on the Notes.

For the avoidance of doubt, in accordance with the benchmark replacement provisions, after a Benchmark Transition Event and its related Benchmark Replacement Date have occurred, the interest rate for each Interest Period will be an annual rate equal to the sum of the Benchmark Replacement plus 1.780%.

3.08 SOFR Index Unavailable Provisions. If a SOFR Index_Start or SOFR Index_End is not published on the associated Interest Payment Determination Date and a Benchmark Transition Event and its related Benchmark Replacement Date have not occurred with respect to SOFR, “Compounded SOFR” means, for the applicable Interest Period for which such index is not available, the rate of return on a daily compounded interest investment calculated in accordance with the formula for SOFR Averages, and definitions required for such formula, published on the SOFR Administrator’s Website at https://www.newyorkfed.org/markets/treasury-repo-reference-rates-information, or any

21

successor source. For the purposes of this provision, references in the SOFR Averages compounding formula and related definitions to “calculation period” shall be replaced with “Observation Period” and the words “that is, 30-, 90-, or 180- calendar days” shall be removed. If SOFR (“SOFRi”) does not so appear for any day, “i” in the Observation Period, SOFRi for such day “i” shall be SOFR published in respect of the first preceding U.S. Government Securities Business Day for which SOFR was published on the SOFR Administrator’s Website.

3.09 Effect of Benchmark Transition Event.

22

Any determination, decision or election pursuant to the benchmark replacement provisions shall be made by the Company or its designee (which may be the Company’s affiliate) on the basis as described above, and in no event shall the Trustee, the Paying Agent or the Calculation Agent be responsible for making any such determination, decision or election.

As used in this “Effect of Benchmark Transition Event” section with respect to any Benchmark Transition Event and implementation of the applicable Benchmark Replacement and Benchmark Replacement Conforming Changes:

“Benchmark” means, initially, Compounded SOFR, as such term is defined in Section 3.07 above; provided that if a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to Compounded SOFR (or the published SOFR Index used in the calculation thereof) or the then-current Benchmark, then “Benchmark” means the applicable Benchmark Replacement.

“Benchmark Replacement” means the first alternative set forth in the order below that can be determined by the Company or its designee as of the Benchmark Replacement Date; provided that if the Benchmark Replacement cannot be determined in accordance with clause (1) below as of the Benchmark Replacement Date and the Company or its designee shall have determined that the ISDA Fallback Rate determined in accordance with clause (2) below is not an industry-accepted rate of interest as a replacement for the then-current Benchmark for U.S. dollar-denominated floating rate Notes at such time, then clause (2) below shall be disregarded, and the Benchmark Replacement shall be determined in accordance with clause (3) below:

“Benchmark Replacement Adjustment” means the first alternative set forth in the order below that can be determined by the Company or its designee as of the Benchmark Replacement Date:

23

“Benchmark Replacement Conforming Changes” means, with respect to any Benchmark Replacement, any technical, administrative or operational changes (including changes to the definitions or interpretations of Interest Period, the timing and frequency of determining rates and making payments of interest, the rounding of amounts or tenors, and other administrative matters) that the Company or its designee decides may be appropriate to reflect the adoption of such Benchmark Replacement in a manner substantially consistent with market practice (or, if the Company or its designee decides that adoption of any portion of such market practice is not administratively feasible or if the Company or its designee determines that no market practice for use of the Benchmark Replacement exists, in such other manner as the Company or its designee determines is reasonably practicable).

“Benchmark Replacement Date” means the earliest to occur of the following events with respect to the then-current Benchmark (including any daily published component used in the calculation thereof):

For the avoidance of doubt, if the event giving rise to the Benchmark Replacement Date occurs on the same day as, but earlier than, the Reference Time in respect of any determination, the Benchmark Replacement Date will be deemed to have occurred prior to the Reference Time for such determination.

“Benchmark Transition Event” means the occurrence of one or more of the following events with respect to the then-current Benchmark (including the daily published component used in the calculation thereof):

24

“Calculation Agent” means the firm appointed by the Company prior to the commencement of the Floating Rate Period. The Company or an affiliate of the Company may assume the duties of the Calculation Agent. The institution serving as Trustee shall have no obligation to serve as Calculation Agent.

“ISDA Definitions” means the 2006 ISDA Definitions published by the International Swaps and Derivatives Association, Inc. (“ISDA”), or any successor thereto, as amended or supplemented from time to time, or any successor definitional booklet for interest rate derivatives published from time to time.

“ISDA Fallback Adjustment” means the spread adjustment (which may be a positive or negative value or zero) that would apply for derivatives transactions referencing the ISDA Definitions to be determined upon the occurrence of an index cessation event with respect to the Benchmark for the applicable tenor.

“ISDA Fallback Rate” means the rate that would apply for derivatives transactions referencing the ISDA Definitions to be effective upon the occurrence of an index cessation date with respect to the Benchmark for the applicable tenor excluding the applicable ISDA Fallback Adjustment.

“Reference Time” with respect to any determination of the Benchmark means (1) if the Benchmark is Compounded SOFR, the SOFR Index Determination Time, as such time is defined above, and (2) if the Benchmark is not Compounded SOFR, the time determined by the Company or its designee in accordance with the Benchmark Replacement Conforming Changes.

25

“Relevant Governmental Body” means the Federal Reserve Board and/or the FRBNY, or a committee officially endorsed or convened by the Federal Reserve Board and/or the FRBNY or any successor thereto.

“Unadjusted Benchmark Replacement” means the Benchmark Replacement excluding the Benchmark Replacement Adjustment.

So long as Compounded SOFR is required to be determined with respect to the Notes, there will at all times be a Calculation Agent during the Floating Rate Period. In the event that any then acting Calculation Agent shall be unable or unwilling to act, or that such Calculation Agent shall fail to duly establish Compounded SOFR for any Interest Period, or the Company proposes to remove such Calculation Agent, the Company will appoint another Calculation Agent (which may be the Company or any of the Company’s affiliates).

None of the Trustee, the Paying Agent and the Calculation Agent shall be under any obligation (i) to monitor, determine or verify the unavailability or cessation of SOFR or the SOFR Index, or whether or when there has occurred, or to give notice to any other transaction party of the occurrence of, any Benchmark Transition Event or related Benchmark Replacement Date, (ii) to select, determine or designate any Benchmark Replacement, or other successor or replacement benchmark index, or whether any conditions to the designation of such a rate or index have been satisfied, (iii) to select, determine or designate any Benchmark Replacement Adjustment, or other modifier to any replacement or successor index, or (iv) to determine whether or what Benchmark Replacement Conforming Changes are necessary or advisable, if any, in connection with any of the foregoing.

None of the Trustee, the Paying Agent and the Calculation Agent shall be liable for any inability, failure or delay on its part to perform any of its duties set forth in this Third Supplemental Indenture as a result of the unavailability of SOFR, the SOFR Index or other applicable Benchmark Replacement, including as a result of any failure, inability, delay, error or inaccuracy on the part of any other transaction party in providing any direction, instruction, notice or information required or contemplated by the terms of this Third Supplemental Indenture and reasonably required for the performance of such duties.

3.10 Amendment to Section 9.01 of the Original Indenture. Solely as it relates to the Notes, Section 9.01(j) of the Original Indenture is amended to replace “.” with “; or” and the following is added as Section 9.01(k) of the Indenture:

“(k) to reflect the occurrence of a Benchmark Transition Event, the selection of a Benchmark Replacement or any Benchmark Replacement Conforming Changes that have been made.”

3.11 No Additional Amounts. For the avoidance of doubt, in the event that any payment on the Notes by the Company or any Paying Agent is subject to withholding of United States federal income tax or other tax or assessment (as a result of a change in law or otherwise), neither the Company nor any Paying Agent shall pay additional amounts to Holders of the Notes.

26

3.12 Optional Redemption of the Notes. The provisions of Article XI of the Indenture shall apply to the Notes, as supplemented or amended by this Section 3.12. The Notes will be redeemable at the Company’s option, in whole or in part, at any time and from time to time, on or after February 12, 2023 (180 days from August 16, 2022) (or, if additional Notes are issued after August 16, 2022, beginning 180 days after the issue date of such additional Notes), and prior to the First Par Call Date (as defined below), at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

plus, in either case, accrued and unpaid interest thereon, if any, to, but excluding, the redemption date.

On the First Par Call Date, the Notes will be redeemable at the Company’s option, in whole, but not in part, at a redemption price equal to 100% of the aggregate principal amount of the Notes, plus accrued and unpaid interest thereon, if any, to, but excluding, the redemption date.

On and after July 17, 2028 (30 days prior to the Maturity Date), the Notes will be redeemable, in whole or in part, at any time and from time to time, at the Company’s option at a redemption price equal to 100% of the aggregate principal amount of the Notes being redeemed, plus accrued and unpaid interest thereon, if any, to, but excluding, the redemption date.

If the Company redeems Notes at its option, then (a) notwithstanding the foregoing, installments of interest on the Notes that are due and payable on any Interest Payment Date falling on or prior to a redemption date for the Notes will be payable on that Interest Payment Date to the registered Holders thereof as of the close of business on the relevant record date according to the terms of the Notes and the Indenture and (b) the redemption price will, if applicable, be calculated on the basis of a 360-day year consisting of twelve 30-day months.

“First Par Call Date” means August 16, 2027 (the date that is one year prior to the Maturity Date).

“Treasury Rate” the yield determined by the Company in accordance with the following two paragraphs.

27

The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the redemption date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily) - H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities–Treasury constant maturities–Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, the Company shall select, as applicable:

(1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the First Par Call Date (the “Remaining Life”); or

(2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields – one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life – and shall interpolate to the First Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or

(3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life.

For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

If on the third business day preceding the redemption date H.15 TCM is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to, the First Par Call Date, as applicable. If there is no United States Treasury security maturing on the First Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the First Par Call Date, one with a maturity date preceding the First Par Call Date and one with a maturity date following the First Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the First Par Call Date. If there are two or more United States Treasury securities maturing on the First Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

28

The Company’s actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error.

3.13 No Sinking Fund. There will be no sinking fund for the Notes. The Notes will not be subject to repayment at the option of the Holder thereof.

3.14 Defeasance and Covenant Defeasance. The Company hereby elects, pursuant to Section 13.01 of the Indenture, to make Sections 13.02 and 13.03 thereof applicable to the Notes.

M&T BANK CORPORATION

4.553% FIXED RATE/FLOATING RATE SENIOR NOTES DUE 2028

CUSIP No. 55261F AQ7

ISIN No. US55261FAQ72

M&T Bank Corporation, a New York corporation which is registered as a bank holding company and a financial holding company under the Bank Holding Company Act of 1956, as amended, and under Article III-A of the New York Banking Law (herein called the “Company”), which term includes any successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay to Cede & Co., or registered assigns, the principal sum of [•] DOLLARS ($[•]) on August 16, 2028 (the “Maturity Date”).

During the period from, and including, August 16, 2022, to, but excluding, August 16, 2027 (the “Fixed Rate Period”), this Security will bear interest at the rate of 4.553% per annum. Such interest will be payable semi-annually, in arrears, on February 16 and August 16 of each year, beginning on February 16, 2023 and ending on August 16, 2027 (each such date a “Fixed Rate Interest Payment Date”). During the Fixed Rate Period, interest will be computed on the basis of a 360-day year consisting of twelve 30-day months.

During the period from, and including, August 16, 2027, to, but excluding, the Maturity Date (the “Floating Rate Period”), this Security will bear interest at a floating rate per annum equal to Compounded SOFR (as defined below) plus 1.780%, as determined in arrears by the Calculation Agent (as defined below) in the manner described below. Such interest will be payable quarterly, in arrears, on November 16, 2027, February 16, 2028, and May 16, 2028 and at the Maturity Date (each such date a “Floating Rate Interest Payment Date”). Compounded SOFR for each Interest Period will be calculated by the Calculation Agent in accordance with the formula set forth in below with respect to the Observation Period (as defined below) relating to such Interest Period.

During the Floating Rate Period, interest will be computed on the basis of the actual number of days in each Interest Period (or any other relevant period) and a 360-day year. The amount of accrued interest payable on this Security for each Interest Period will be computed by multiplying (i) the outstanding principal amount of this Security by (ii) the product of (a) the interest rate for the relevant Interest Period multiplied by (b) the quotient of the actual number of calendar days in the applicable Interest Period (or any other relevant period) divided by 360. The interest rate on this Security will in no event be higher than the maximum rate permitted by New York law as the same may be modified by United States law of general application and will in no event be lower than zero.

The Calculation Agent will determine Compounded SOFR, the interest rate and accrued interest for each Interest Period in arrears as soon as reasonably practicable on or after the Interest Payment Determination Date (as defined below) for such Interest Period and prior to the relevant Interest Payment Date and will notify the Company (if the Company is not the Calculation Agent) of the Compounded SOFR, such interest rate and accrued interest for each

-2-

Interest Period as soon as reasonably practicable after such determination, but in any event by the Business Day immediately prior to the Interest Payment Date. At the request of the Holder of this Security, the Company will provide the Compounded SOFR, the interest rate and the amount of interest accrued with respect to any Interest Period, after the Compounded SOFR, such interest rate and accrued interest have been determined. The Calculation Agent’s determination of any interest rate, and its calculation of interest payments for any Interest Period during the Floating Rate Period, will be maintained on file at the Calculation Agent’s principal offices and will be provided in writing to the Trustee. All determinations made by the Calculation Agent shall, in the absence of manifest error, be conclusive for all purposes and binding on the Company and the Holder of this Security.

If any Fixed Rate Interest Payment Date on or before August 16, 2027, any redemption date or the Maturity Date falls on a day that is not a Business Day, then payment of any interest, principal or premium payable on such date will be postponed to the next succeeding Business Day, with the same force and effect as if made on the date such payment was due, and no interest or other payment will accrue as a result of such delay. If any Floating Rate Interest Payment Date after August 16, 2027, other than any Floating Rate Interest Payment Date that is a redemption date or the Maturity Date, falls on a day that is not a Business Day, then payment of any interest payable on such date will be postponed to the next succeeding Business Day, except that, if the next succeeding Business Day falls in the next calendar month, then such interest payment will be advanced to the immediately preceding day that is a Business Day and, in each case, the related Interest Periods also will be adjusted for such non-Business Days. The term “Interest Payment Date” means a Fixed Rate Interest Payment Date or a Floating Rate Interest Payment Date. The term “Interest Period” means the period from and including August 16, 2022, or from and including the most recent Interest Payment Date (whether or not such Interest Payment Date was a Business Day) for which interest has been paid or provided for with respect to this Security to, but excluding, the next Interest Payment Date, redemption date or the Maturity Date, as the case may be.

“Business Day” means any day that is not a Saturday or Sunday and that is not a day on which banking institutions are generally authorized or obligated by law or executive order to close in The City of New York or the City of Buffalo, New York or on which the Corporate Trust office of the Trustee is closed for business.

The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as and to the extent provided in such Indenture, be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest, which shall be the 15^th calendar day (whether or not a Business Day) preceding the related Interest Payment Date or, if this Security is in the form of a Global Security, the close of business on the Business Day preceding the related Interest Payment Date, except that interest payable on the Maturity Date or (subject to the exceptions described in Section 11.06(a) of the Indenture) any Redemption Date will be paid to the Person to whom principal is paid. Any such interest not so punctually paid or duly provided for will forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed in the manner described in the Indenture, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities of this series may be listed, and upon such notice as may be required by such exchange, all as more fully provided in said Indenture. This Security is a Security for purposes of the Indenture.

-3-

Compounded SOFR

With respect to any Interest Period during the Floating Rate Period, “Compounded SOFR” will be determined by the Calculation Agent in accordance with the following formula (and the resulting percentage will be rounded, if necessary, to the nearest one hundred-thousandth of a percentage point, with 0.00000005, or 0.000005%, being rounded upwards):

where:

“SOFR Index_Start” means, for periods other than the initial Interest Period in the Floating Rate Period, the SOFR Index value on the preceding Interest Payment Determination Date, and, for the initial Interest Period in the Floating Rate Period, the SOFR Index value on the date that is two U.S. Government Securities Business Days before the first day of such initial Interest Period;

“SOFR Index_End” means the SOFR Index value on the Interest Payment Determination Date relating to the applicable Interest Payment Date (or in the final Interest Period, relating to the Maturity Date, or, in the case of the redemption of this Security, relating to the applicable redemption date); and

“d” is the number of calendar days in the relevant Observation Period.

For purposes of determining Compounded SOFR,

“Interest Payment Determination Date” means the date two U.S. Government Securities Business Days before each Interest Payment Date (or in the final Interest Period, preceding the Maturity Date, or in the case of the redemption of this Security, preceding the applicable redemption date, as the case may be).

“Observation Period” means, in respect of each Interest Period, the period from, and including, the date two U.S. Government Securities Business Days preceding the first date in such Interest Period to, but excluding, the date two U.S. Government Securities Business Days preceding the Interest Payment Date for such Interest Period (or in the final Interest Period, preceding the Maturity Date or, in the case of the redemption of this Security, preceding the applicable redemption date).

“SOFR” means the daily secured overnight financing rate as provided by the SOFR Administrator on the SOFR Administrator’s Website.

“SOFR Administrator” means the Federal Reserve Bank of New York (the “FRBNY”) (or a successor administrator of SOFR).

-4-

“SOFR Index” means, with respect to any U.S. Government Securities Business Day:

“U.S. Government Securities Business Day” means any day except for a Saturday, a Sunday or a day on which the Securities Industry and Financial Markets Association or any successor organization recommends that the fixed income departments of its members be closed for the entire day for purposes of trading in U.S. government securities.

Notwithstanding anything to the contrary in the Indenture, this Security or any other Securities of this series, if the Company or its designee determines on or prior to the relevant Reference Time (as defined below) that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to determining SOFR, then the benchmark replacement provisions set forth below will thereafter apply to all determinations of the rate of interest payable on this Security and any other Securities of this series.

For the avoidance of doubt, in accordance with the benchmark replacement provisions, after a Benchmark Transition Event and its related Benchmark Replacement Date have occurred, the interest rate for each Interest Period will be an annual rate equal to the sum of the Benchmark Replacement plus 1.780%.

SOFR Index Unavailable Provisions

If a SOFR Index_Start or SOFR Index_End is not published on the associated Interest Payment Determination Date and a Benchmark Transition Event and its related Benchmark Replacement Date have not occurred with respect to SOFR, “Compounded SOFR” means, for the applicable Interest Period for which such index is not available, the rate of return on a daily compounded interest investment calculated in accordance with the formula for SOFR Averages, and definitions required for such formula, published on the SOFR Administrator’s Website at https://www.newyorkfed.org/markets/treasury-repo-reference-rates-information, or any successor source. For the purposes of this provision, references in the SOFR Averages compounding formula and related definitions to “calculation period” shall be replaced with “Observation Period” and the words “that is, 30-, 90-, or 180- calendar days” shall be removed.

-5-

If SOFR (“SOFRi”) does not so appear for any day, “i” in the Observation Period, SOFRi for such day “i” shall be SOFR published in respect of the first preceding U.S. Government Securities Business Day for which SOFR was published on the SOFR Administrator’s Website.

Effect of Benchmark Transition Event

Any determination, decision or election pursuant to the benchmark replacement provisions shall be made by the Company or its designee (which may be the Company’s affiliate) on the basis as described above, and in no event shall the Trustee, the Paying Agent or the Calculation Agent be responsible for making any such determination, decision or election.

-6-

As used in this “Effect of Benchmark Transition Event” section with respect to any Benchmark Transition Event and implementation of the applicable Benchmark Replacement and Benchmark Replacement Conforming Changes:

“Benchmark” means, initially, Compounded SOFR, as such term is defined above; provided that if a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to Compounded SOFR (or the published SOFR Index used in the calculation thereof) or the then-current Benchmark, then “Benchmark” means the applicable Benchmark Replacement.

“Benchmark Replacement” means the first alternative set forth in the order below that can be determined by the Company or its designee as of the Benchmark Replacement Date; provided that if the Benchmark Replacement cannot be determined in accordance with clause (1) below as of the Benchmark Replacement Date and the Company or its designee shall have determined that the ISDA Fallback Rate determined in accordance with clause (2) below is not an industry-accepted rate of interest as a replacement for the then-current Benchmark for U.S. dollar-denominated floating rate notes at such time, then clause (2) below shall be disregarded, and the Benchmark Replacement shall be determined in accordance with clause (3) below:

-7-

“Benchmark Replacement Conforming Changes” means, with respect to any Benchmark Replacement, any technical, administrative or operational changes (including changes to the definitions or interpretations of Interest Period, the timing and frequency of determining rates and making payments of interest, the rounding of amounts or tenors, and other administrative matters) that the Company or its designee decides may be appropriate to reflect the adoption of such Benchmark Replacement in a manner substantially consistent with market practice (or, if the Company or its designee decides that adoption of any portion of such market practice is not administratively feasible or if the Company or its designee determines that no market practice for use of the Benchmark Replacement exists, in such other manner as the Company or its designee determines is reasonably practicable).

“Benchmark Replacement Date” means the earliest to occur of the following events with respect to the then-current Benchmark (including any daily published component used in the calculation thereof):

For the avoidance of doubt, if the event giving rise to the Benchmark Replacement Date occurs on the same day as, but earlier than, the Reference Time in respect of any determination, the Benchmark Replacement Date will be deemed to have occurred prior to the Reference Time for such determination.

“Benchmark Transition Event” means the occurrence of one or more of the following events with respect to the then-current Benchmark (including the daily published component used in the calculation thereof):

-8-

“Calculation Agent” means the firm appointed by the Company prior to the commencement of the Floating Rate Period. The Company or an affiliate of the Company may assume the duties of the Calculation Agent. The institution serving as Trustee shall have no obligation to serve as Calculation Agent.

“ISDA Definitions” means the 2006 ISDA Definitions published by the International Swaps and Derivatives Association, Inc. (“ISDA”), or any successor thereto, as amended or supplemented from time to time, or any successor definitional booklet for interest rate derivatives published from time to time.

“ISDA Fallback Adjustment” means the spread adjustment (which may be a positive or negative value or zero) that would apply for derivatives transactions referencing the ISDA Definitions to be determined upon the occurrence of an index cessation event with respect to the Benchmark for the applicable tenor.

“ISDA Fallback Rate” means the rate that would apply for derivatives transactions referencing the ISDA Definitions to be effective upon the occurrence of an index cessation date with respect to the Benchmark for the applicable tenor excluding the applicable ISDA Fallback Adjustment.

“Reference Time” with respect to any determination of the Benchmark means (1) if the Benchmark is Compounded SOFR, the SOFR Index Determination Time, as such time is defined above, and (2) if the Benchmark is not Compounded SOFR, the time determined by the Company or its designee in accordance with the Benchmark Replacement Conforming Changes.

“Relevant Governmental Body” means the Federal Reserve Board and/or the FRBNY, or a committee officially endorsed or convened by the Federal Reserve Board and/or the FRBNY or any successor thereto.

“Unadjusted Benchmark Replacement” means the Benchmark Replacement excluding the Benchmark Replacement Adjustment.

So long as Compounded SOFR is required to be determined with respect to the Securities of this series, there will at all times be a Calculation Agent during the Floating Rate Period. In the event that any then acting Calculation Agent shall be unable or unwilling to act, or that such Calculation Agent shall fail to duly establish Compounded SOFR for any Interest Period, or the Company proposes to remove such Calculation Agent, the Company will appoint another Calculation Agent (which may be the Company or any of the Company’s affiliates).

-9-

None of the Trustee, the Paying Agent and the Calculation Agent shall be under any obligation (i) to monitor, determine or verify the unavailability or cessation of SOFR or the SOFR Index, or whether or when there has occurred, or to give notice to any other transaction party of the occurrence of, any Benchmark Transition Event or related Benchmark Replacement Date, (ii) to select, determine or designate any Benchmark Replacement, or other successor or replacement benchmark index, or whether any conditions to the designation of such a rate or index have been satisfied, (iii) to select, determine or designate any Benchmark Replacement Adjustment, or other modifier to any replacement or successor index, or (iv) to determine whether or what Benchmark Replacement Conforming Changes are necessary or advisable, if any, in connection with any of the foregoing.

None of the Trustee, the Paying Agent and the Calculation Agent shall be liable for any inability, failure or delay on its part to perform any of its duties set forth in the Third Supplemental Indenture or this Security as a result of the unavailability of SOFR, the SOFR Index or other applicable Benchmark Replacement, including as a result of any failure, inability, delay, error or inaccuracy on the part of any other transaction party in providing any direction, instruction, notice or information required or contemplated by the terms of the Third Supplemental Indenture or this Security and reasonably required for the performance of such duties.

Payment of the principal of (and premium, if any) and any such interest on this Security will be made at the office or agency of The Bank of New York Mellon, as Paying Agent, maintained for that purpose in New York, New York in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided, however, that at the option of the Company payment of principal, premium (if any) or interest may be made by wire transfer in same-day funds to an account designated by the Person entitled thereto or by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register; provided further that if this Security is a Global Security payment of the principal, premium or interest will be made in accordance with the Applicable procedures.

Reference is hereby made to the further provisions of this Security set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place.

Unless the certificate of authentication hereon has been executed by the Trustee referred to on the reverse hereof by manual signature (or, solely in the case of a Global Security, facsimile or electronic signature), this Security shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

This Security shall be governed by and construed in accordance with the laws of the State of New York.

[Reverse of Security]

This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Indenture, dated as of May 24, 2007 (the “Base Indenture”), between the Company and The Bank of New York (now doing business as The Bank of New York Mellon), as Trustee, as supplemented by the Third Supplemental Indenture thereto, dated as of August 16, 2022 (the “Third Supplemental Indenture”, and together with the Base Indenture, the “Indenture”), between the Company and The Bank of New York Mellon, as Trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered; provided that to the extent of any inconsistency between the terms and provisions in the Indenture and those contained in this Security, the Indenture shall govern. This Security is one of the series designated on the face hereof. All terms used in this Security which are defined in the Indenture and not otherwise defined herein shall have the meanings assigned to them in the Indenture.

This Security will be redeemable at the Company’s option, in whole or in part, at any time and from time to time, on or after February 12, 2023 (180 days from August 16, 2022) (or, if additional Securities of this series are issued after August 16, 2022, beginning 180 days after the issue date of such additional Securities), and prior to the First Par Call Date (as defined below), at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

plus, in either case, accrued and unpaid interest thereon, if any, to, but excluding, the redemption date.

On the First Par Call Date, this Security will be redeemable at the Company’s option, in whole, but not in part, at a redemption price equal to 100% of the aggregate principal amount of this Security, plus accrued and unpaid interest thereon, if any, to, but excluding, the redemption date.

On and after July 17, 2028 (30 days prior to the Maturity Date), this Security will be redeemable, in whole or in part, at any time and from time to time, at the Company’s option at a redemption price equal to 100% of the aggregate principal amount of the principal amount of this Security being redeemed, plus accrued and unpaid interest thereon, if any, to, but excluding, the redemption date.

-13-

If the Company redeems this Security at its option, then (a) notwithstanding the foregoing, installments of interest on this Security that are due and payable on any Interest Payment Date falling on or prior to a redemption date for this Security will be payable on that Interest Payment Date to the registered Holder hereof as of the close of business on the relevant record date according to the terms of this Security and the Indenture and (b) the redemption price will, if applicable, be calculated on the basis of a 360-day year consisting of twelve 30-day months.

“First Par Call Date” means August 16, 2027 (the date that is one year prior to the Maturity Date).

“Treasury Rate” the yield determined by the Company in accordance with the following two paragraphs.

The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the redemption date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily)—H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities–Treasury constant maturities–Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, the Company shall select, as applicable:

(1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the First Par Call Date (the “Remaining Life”); or

(2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields – one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life – and shall interpolate to the First Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or

(3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life.

For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

If on the third business day preceding the redemption date H.15 TCM is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to, the First Par Call Date, as applicable. If there is no United States Treasury security maturing on the First Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the First Par Call Date, one with a

-14-

maturity date preceding the First Par Call Date and one with a maturity date following the First Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the First Par Call Date. If there are two or more United States Treasury securities maturing on the First Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time.

Ladies and Gentlemen:

In connection with the registration, under the Securities Act of 1933 (the “Act”) of $500,000,000 aggregate principal amount of 4.553% Fixed Rate/Floating Rate Senior Notes due 2028 (the “Securities”) of M&T Bank Corporation, a New York corporation (the “Company”), we, as your counsel, have examined such corporate records, certificates and other documents, and such questions of law, as we have considered necessary or appropriate for the purposes of this opinion.

Upon the basis of such examination, it is our opinion that the Securities constitute valid and legally binding obligations of the Company, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles.

In rendering the foregoing opinion, we are expressing no opinion as to Federal or state laws relating to fraudulent transfers and we are not passing upon, and assume no responsibility for, any disclosure in any registration statement or any related prospectus or other offering material relating to the offer and sale of the Securities.

The foregoing opinion is limited to the Federal laws of the United States and the laws of the State of New York, and we are expressing no opinion as to the effect of the laws of any other jurisdiction.

We have relied as to certain factual matters on information obtained from public officials, officers of the Company and other sources believed by us to be responsible, and we have assumed that the Indenture and Supplemental Indenture under which the Securities were issued have been duly authorized, executed and delivered by the Trustee thereunder, that the Securities conform to the specimen thereof examined by us, that the Trustee’s certificate of authentication of the Securities has been signed by one of the Trustee’s authorized officers, and that the signatures on all documents examined by us are genuine, assumptions which we have not independently verified.

We hereby consent to the filing of this opinion as an exhibit to a Current Report on Form 8-K to be filed by the Company on the date hereof and its incorporation by reference into the Registration Statement relating to the Securities (File No. 333-259888) and to the reference to us under the caption “Validity of Securities” in the Prospectus Supplement relating to the Securities, dated August 9, 2022, which is a part of the Registration Statement. In giving such consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Act.
