GENERAL TERMS AND CONDITIONS OF THE NOTES.

Section 2.01 Designation and Principal Amount The Notes may be issued from time to time upon written order of the Company for the authentication and delivery of Notes pursuant to Section 3.3 of the Base Indenture. There is hereby authorized a series of Securities designated as the 5.272% Fixed-to-Floating Rate Senior Notes due 2031 having an initial aggregate principal amount of $1,150,000,000.

Section 2.02 Maturity The date upon which the Notes shall become due and payable at final maturity, together with any accrued and unpaid interest, is January 15, 2031 (the “Maturity Date”) unless earlier redeemed or repaid.

Section 2.03 Form, Payment and Appointment. Except as provided in the last three paragraphs of Section 3.5 of the Base Indenture, the Notes will be issued only in book-entry form. Principal of and interest on the Notes will be payable in global form registered in the name of or held by The Depository Trust Company (“DTC”) or its nominee in immediately available funds to DTC or its nominee, as the case may be, as the registered holder of such Global Note (as hereinafter defined). The principal of any certificated Notes will be payable at the office or

-7-

agency of the Company maintained for such purpose in the Borough of Manhattan, New York City, New York, which shall initially be the principal office of the Trustee in the Borough of Manhattan, the City of New York; provided, however, that payment of interest may be made at the option of the Company by check mailed to the Person entitled thereto at such address as shall appear in the Security Register or by wire transfer to an account appropriately designated by the Person entitled to payment; provided that the paying agent shall have received written notice of such account designation at least five Business Days prior to the date of such payment (subject to surrender of the relevant Note in the case of a payment of interest on the Maturity Date).

The Company hereby appoints the Trustee to act as Security Registrar, Calculation Agent and Paying Agent for the Notes.

The Notes will be issuable and may be transferred only in denominations of $2,000 or any amount in excess thereof that is an integral multiple of $1,000. The specified currency of the Notes shall be U.S. Dollars.

Section 2.04 Global Note. The Notes shall be issued initially in the form of one or more fully registered global notes (each such global note, a “Global Note”) deposited with DTC or its designated custodian or such other Depositary as any officer of the Company may from time to time designate. Unless and until a Global Note is exchanged for Notes in certificated form, such Global Note may be transferred, in whole but not in part, and any payments on the Notes shall be made, only to DTC or a nominee of DTC, or to a successor Depositary selected or approved by the Company or to a nominee of such successor Depositary.

Section 2.05 Interest.

(a) (i) Fixed Rate Period. During the period from (and including) November 18, 2024, to (but excluding) January 15, 2030, the Notes will bear interest at the rate of 5.272% per annum (the “Initial Interest Rate”). Such interest will be payable semi-annually in arrears on each January 15 and July 15 of each year, beginning on January 15, 2025 and ending on January 15, 2030 (each, a “Fixed Rate Period Interest Payment Date”). Interest will be computed on the basis of a 360-day year consisting of twelve 30-day months. If any scheduled Fixed Rate Period Interest Payment Date is not a Business Day, any payment of principal and interest on the Notes will be postponed to the next day that is a Business Day, but interest on that payment will not accrue during the period from and after the scheduled Fixed Rate Period Interest Payment Date.

(b) (i) Floating Rate Period. During the period from (and including) January 15, 2030, to (but excluding) the Maturity Date (the “Floating Rate Period”), the Notes will bear interest at a floating rate per annum equal to the Benchmark plus 127.6 basis points per annum (the “Spread”), as determined in arrears by the Calculation Agent in the manner described herein, subject to the terms of the Interest Calculation Agreement. Such interest will be payable quarterly in arrears on April 15, 2030, July 15, 2030, October 15, 2030 and on the Maturity Date (each a “Floating Rate Period Interest Payment Date”). Such interest will be computed for the period beginning on (and including) a Floating Rate Period Interest Payment Date and ending on (but excluding) the next succeeding Floating Rate Period Interest Payment Date or the Maturity Date or date of redemption or repayment (each, a “Floating Rate Interest Period”); provided that the first Floating Rate Interest Period for the Notes will begin on (and include) January 15, 2030 and will end on (but exclude) the first Floating Rate Period Interest Payment Date.

-8-

(ii) The Calculation Agent will calculate the interest rate on the Notes quarterly on the second U.S. Government Securities Business Day preceding the applicable Floating Rate Period Interest Payment Date, except as described below (the “Interest Determination Date”). In no event will the interest payable on the Notes be less than zero. Interest will be computed on the basis of the actual number of days in each Floating Rate Interest Period and a 360-day year. The amount of accrued interest payable on the Notes for each Floating Rate 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 Floating Rate Interest Period multiplied by (b) the quotient of the actual number of calendar days in the applicable Floating Rate Interest Period relating to such Floating Rate Interest Period divided by 360.

(iii) If any scheduled Floating Rate Period Interest Payment Date (other than the Maturity Date) is not a Business Day, such Floating Rate Period Interest Payment Date will be postponed to the next day that is a Business Day; provided that if that Business Day falls in the next succeeding calendar month, such Floating Rate Period Interest Payment Date will be the immediately preceding Business Day. If any such Floating Rate Period Interest Payment Date (other than the Maturity Date) is postponed or brought forward as described above, the payment of interest due on such postponed or brought forward Floating Rate Period Interest Payment Date will include interest accrued to (but excluding) such postponed or brought forward Floating Rate Period Interest Payment Date.

(c) Interest on the Notes shall be payable to the Persons in whose names the relevant Notes are registered at the close of business on the fifteenth calendar day preceding each Floating Rate Period Interest Payment Date or Fixed Rate Period Interest Payment Date, as applicable, whether or not a Business Day.

(d) In the event that the Maturity Date or date of redemption, or repayment of any Note falls on a day that is not a Business Day, then the related payments of principal, premium, if any, and interest may be made on the next succeeding day that is a Business Day, but interest on that payment will not accrue during the period from and after the Maturity Date or date of redemption or repayment of any Note. If a date of redemption or repayment of any Note falls within the Floating Rate Period but does not occur on a Floating Rate Period Interest Payment Date, (i) the related Interest Determination Date shall be deemed to be the date that is two U.S. Government Securities Business Days prior to such date of redemption or repayment, (ii) the related Observation Period shall be deemed to end on (and exclude) the second U.S. Government Securities Business Day falling prior to such date of redemption or repayment, (iii) the Floating Rate Interest Period will be deemed to be shortened accordingly and (iv) corresponding adjustments will be deemed to be made to the Compounded SOFR Index Rate formula (or applicable Benchmark). Interest due on the Maturity Date of any Notes will be paid to the Person to whom principal of such Notes is payable.

(e) SOFR Index Unavailability. If SOFR IndexStart or SOFR IndexEnd is not published on the relevant Interest Determination Date and a Benchmark Transition Event and its related Benchmark Replacement Date have not occurred with respect to SOFR, “Compounded

-9-

SOFR Index Rate” shall mean, for the relevant 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 such successor website). 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 the daily 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.

(f) Benchmark Transition Provisions. (i) In the event that the Company or its designee (in consultation with the Company) determines that a Benchmark Transition Event and related Benchmark Replacement Date have occurred prior to the applicable Reference Time in respect of any determination of the Benchmark on any date, the applicable Benchmark Replacement shall replace the then-current Benchmark for all purposes relating to the Notes during the Floating Rate Period in respect of such determination on such date and all determinations on all subsequent dates; provided that, if the Company or its designee (in consultation with the Company) is unable to or does not determine a Benchmark Replacement in accordance with the provisions below prior to 5:00 p.m. (New York time) on the relevant Interest Determination Date, the interest rate for the related Floating Rate Interest Period shall be equal to the interest rate in effect for the immediately preceding Floating Rate Interest Period or, in the case of the Interest Determination Date prior to the first Floating Rate Period Interest Payment Date, the Initial Interest Rate. In accordance with and subject to this Section 2.05(f), after a Benchmark Transition Event and related Benchmark Replacement Date have occurred, the amount of interest that will be payable for each interest period on the Notes during the Floating Rate Period will be determined by reference to a rate per annum equal to the Benchmark Replacement plus the Spread.

(ii) In connection with the implementation of a Benchmark Replacement, the Company or its designee (in consultation with the Company) shall have the right to make changes to (1) any Interest Determination Date, Floating Rate Period Interest Payment Date, Reference Time, Business Day convention or Floating Rate Interest Period, (2) the manner, timing and frequency of determining the rate and amounts of interest that are payable on the Notes during the Floating Rate Period and the conventions relating to such determination and calculations with respect to interest, (3) rounding conventions, (4) tenors and (5) any other terms or provisions of the Notes during the Floating Rate Period, in each case that the Company or its designee (in consultation with the Company) determines, from time to time, to be appropriate to reflect the determination and implementation of such Benchmark Replacement in a manner substantially consistent with market practice (or, if the Company or its designee (in consultation with the Company) decides that implementation of any portion of such market practice is not administratively feasible or determine that no market practice for use of the Benchmark Replacement exists, in such other manner as the Company or its designee (in consultation with the Company) determines is appropriate (acting in good faith)) (the “Benchmark Replacement Conforming Changes”). Any Benchmark Replacement Conforming Changes shall apply to the Notes for all future Floating Rate Interest Periods.

-10-

(iii) The Company shall promptly give notice of the determination of the Benchmark Replacement, the Benchmark Replacement Adjustment and any Benchmark Replacement Conforming Changes to the Trustee, the Paying Agent, the Calculation Agent and the Holders of the Notes; provided that failure to provide such notice shall have no impact on the effectiveness of, or otherwise invalidate, any such determination.

(iv) All determinations, decisions, elections and any calculations made by the Company or its designee for the purposes of determining the Benchmark Replacement, the Benchmark Replacement Adjustment and any Benchmark Replacement Conforming Changes shall be conclusive and binding on the Holders of the Notes, the Company, the Calculation Agent, the Trustee and the Paying Agent, absent manifest error. If made by the Company’s designee, such determinations, decisions, elections and calculations shall be made after consulting with the Company, and such designees shall not make any such determination, decision, election or calculation to which the Company objects. Notwithstanding anything to the contrary in this Indenture, any determinations, decisions, calculations or elections made in accordance with this provision shall become effective without consent from the Holders of the Notes or any other party.

(v) Any determination, decision or election relating to the Benchmark shall be made by the Company in accordance with this Section 2.05(f). None of the Calculation Agent, the Trustee or the Paying Agent shall have any liability for not making any such determination, decision or election. The Company may designate an entity (which may be its affiliate) to make any determination, decision or election that the Company has the right to make in connection with the determination of the Benchmark.

(vi) Notwithstanding any other provision in this Section 2.05(f), no Benchmark Replacement shall be adopted, nor shall the applicable Benchmark Replacement Adjustment be applied, nor shall any Benchmark Replacement Conforming Changes be made, if in the Company’s determination, the same could reasonably be expected to prejudice the qualification of the Notes as eligible liabilities or loss absorbing capacity instruments for the purposes of the Relevant Rules.

(vii) Each Holder of the Notes (including each Holder of a beneficial interest in the Notes) (i) acknowledges, accepts, consents and agrees to be bound by the Company’s or its designee’s determination of a Benchmark Transition Event, a Benchmark Replacement Date, the Benchmark Replacement, the Benchmark Replacement Adjustment and any Benchmark Replacement Conforming Changes, including as may occur without any prior notice from the Company and without the need for the Company to obtain any further consent from such Holder of the Notes, (ii) waives any and all claims, in law and/or in equity, against the Trustee, the Paying Agent and the Calculation Agent or the Company’s designee for, agrees not to initiate a suit against the Trustee, the Paying Agent and the Calculation Agent or the Company’s designee in respect of, and agrees that none of the Trustee, the Paying Agent or the Calculation Agent or the Company’s designee shall be liable for, the determination of or the Company’s failure or delay (including any failure to perform their duties as a result of the Company’s or its designee’s failure or delay) to determine any Benchmark Transition Event, any Benchmark Replacement Date, any Benchmark Replacement, any Benchmark Replacement Adjustment and any Benchmark Replacement Conforming Changes, and any losses suffered in connection therewith and (iii) agrees that none of the Trustee, the Paying Agent or the Calculation Agent or the Company’s designee will have any

-11-

obligation to determine, confirm or verify any Benchmark Transition Event, any Benchmark Replacement Date, any Benchmark Replacement, any Benchmark Replacement Adjustment and any Benchmark Replacement Conforming Changes (including any adjustments thereto), including in the event of any failure or delay by the Company to determine any Benchmark Transition Event, any Benchmark Replacement Date, any Benchmark Replacement, any Benchmark Replacement Adjustment and any Benchmark Replacement Conforming Changes.

(viii) All percentages resulting from any calculation of any interest rate for the Notes shall be rounded, if necessary, to the nearest one hundred thousandth of a percentage point, with five one-millionths of a percentage point rounded upward (e.g., 9.876545% (or ..09876545) would be rounded to 9.87655% (or .0987655)), and all dollar amounts would be rounded to the nearest cent, with one-half cent being rounded upward.

Section 2.06 No Sinking Fund. The Notes are not entitled to the benefit of any sinking fund.

Not later than 10:00 a.m. (New York City time) on each due date of the principal of, premium, if any, and interest on any Notes, the Company shall deposit with the Paying Agent money in immediately available funds sufficient to pay such principal, redemption payments, premium, if any, and interest so becoming due.

ARTICLE 3

REDEMPTION OF THE NOTES.

Section 3.01 Optional Redemption. The Notes are not subject to redemption at the option of the Company at any time except as described herein. The Notes are subject to redemption at the option of the Company, in accordance with Exhibit A of the attached and in accordance with Article XI of the Base Indenture.

On or after May 17, 2025 (180 days after November 18, 2024) (or, if additional notes are issued, beginning 180 days after the issue date of such additional notes), and, prior to January 15, 2030 (one year prior to the Maturity Date (the “First Par Call Date”)), the Company may redeem the Notes at its option, in whole or in part, at any time and from time to time, 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 to the redemption date.

-12-

On the First Par Call Date, the Company may redeem the Notes, in whole but not in part, or on or after December 15, 2030 (one month prior to the Maturity Date), in whole or in part, at any time and from time to time, in each case at a redemption price equal to 100% of the principal amount of the Notes being redeemed plus accrued and unpaid interest thereon to the redemption date.

“Treasury Rate” means, with respect to any redemption date, 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 or any successor designation or publication 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.

-13-

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

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the Depositary’s procedures) at least 5 days but not more than 60 days before the redemption date to each Holder of the Notes to be redeemed.

In the case of a partial redemption, selection of the Notes for redemption will be made pro rata, by lot or by such other method as the Trustee in its sole discretion deems appropriate and fair. No Notes of a principal amount of $2,000 or less will be redeemed in part. If any Note is to be redeemed in part only, the notice of redemption that relates to the Note shall state the portion of the principal amount of the Note to be redeemed. A new note in a principal amount equal to the unredeemed portion of the Note shall be issued in the name of the Holder of the Note upon surrender for cancellation of the original Note. For so long as the Notes are held by DTC (or another Depositary), the redemption of the Notes shall be done in accordance with the policies and procedures of the Depositary.

Neither the Trustee nor the Calculation Agent shall be responsible for or have any responsibility to determine or make any calculations in connection with any redemption.

If any Notes are redeemed, the redemption price payable to the holder of any Notes called for redemption will be payable on the applicable redemption date against the surrender to the Company or its agent of any certificate(s) evidencing the Notes called for redemption. If money sufficient to pay the redemption price of, and any accrued interest on, the Notes (or portions thereof) to be redeemed on the redemption date is deposited with the Paying Agent on or before the redemption date and certain other conditions are satisfied, then on and after the redemption date, interest will cease to accrue on the Notes (or such portion thereof) called for redemption and such Notes will cease to be outstanding.

The Notes are not be subject to repayment at the option of any Holder at any time prior to maturity and are not entitled to any sinking fund.

Section 10.06 Additional Trustee Provisions.

(a) Delivery to the Trustee of any reports, information and documents pursuant to the Base Indenture is for informational purposes only and the Trustee’s receipt of such reports, information and documents shall not constitute actual or constructive notice or knowledge of any information contained therein or determinable from information contained therein, including the compliance of the Company with any of its covenants in the Base Indenture and this Eighth Supplemental Indenture (as to which the Trustee is entitled to conclusively rely exclusively on Officers’ Certificates).

(b) The Trustee may request that the Company deliver an Officers’ Certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to the Base Indenture and this Eighth Supplemental Indenture, which Officers’ Certificate may be signed by any person authorized to sign an Officers’ Certificate, including any person specified as so authorized in any such certificate previously delivered and not superseded.

HUNTINGTON BANCSHARES INCORPORATED

5.272% FIXED-TO-FLOATING RATE SENIOR

NOTES DUE 2031

CUSIP NO. 446150BE3

ISIN US446150BE30

HUNTINGTON BANCSHARES INCORPORATED, a Maryland corporation (herein called the “Company”, which term includes any successor Person under the Indenture referred to on the reverse hereof), for value received, hereby promises to pay to Cede & Co., or its registered assigns, the principal sum of [five hundred] [one hundred and fifty] million United States dollars on January 15, 2031 and all accrued and unpaid interest thereon on January 15, 2031, or if such day is not a Business Day, the following Business Day.

The Company further promises to pay interest as follows. During the period from (and including) November 18, 2024, to (but excluding) January 15, 2030, the Notes will bear interest at the rate of 5.272% per annum. Such interest will be payable semi-annually in arrears on each January 15 and July 15 of each year, beginning on January 15, 2025 and ending on January 15, 2030 (each, a “Fixed Rate Period Interest Payment Date”). Interest will be computed on the basis of a 360-day year consisting of twelve 30-day months. If any scheduled Fixed Rate Period Interest Payment Date is not a Business Day, any payment of principal and interest on the Notes will be postponed to the next day that is a Business Day, but interest on that payment will not accrue during the period from and after the scheduled Fixed Rate Period Interest Payment Date.

During the period from (and including) January 15, 2030, to (but excluding) the Maturity Date (the “Floating Rate Period”), the Notes will bear interest at a floating rate per annum equal to the Benchmark plus 127.6 basis points per annum (the “Spread”), as determined in arrears by the Calculation Agent in the manner described herein and in the Indenture. Such interest will be payable quarterly in arrears on April 15, 2030, July 15, 2030, October 15, 2030 and on the Maturity Date (each a “Floating Rate Period Interest Payment Date”). Such interest will be computed for the period beginning on (and including) a Floating Rate Period Interest Payment Date and ending on (but excluding) the next succeeding Floating Rate Period Interest Payment Date or the Maturity Date or date of redemption or repayment (each, a “Floating Rate Interest Period”); provided that the first Floating Rate Interest Period for the Notes will begin on (and include) January 15, 2030 and will end on (but exclude) the first Floating Rate Period Interest Payment Date.

The Calculation Agent will calculate the interest rate on the Notes quarterly on the second U.S. Government Securities Business Day preceding the applicable Floating Rate Period Interest Payment Date, except as described below (the “Interest Determination Date”). In no event will the interest payable on the Notes be less than zero. Interest will be computed on the basis of the actual number of days in each Floating Rate Interest Period and a 360-day year. The amount of accrued interest payable on the Notes for each Floating Rate 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 Floating Rate Interest Period multiplied by (b) the quotient of the actual number of calendar days in the applicable Floating Rate Interest Period relating to such Floating Rate Interest Period divided by 360.

A-3

If any scheduled Floating Rate Period Interest Payment Date (other than the Maturity Date) is not a Business Day, such Floating Rate Period Interest Payment Date will be postponed to the next day that is a Business Day; provided that if that Business Day falls in the next succeeding calendar month, such Floating Rate Period Interest Payment Date will be the immediately preceding Business Day. If any such Floating Rate Period Interest Payment Date (other than the Maturity Date) is postponed or brought forward as described above, the payment of interest due on such postponed or brought forward Floating Rate Period Interest Payment Date will include interest accrued to (but excluding) such postponed or brought forward Floating Rate Period Interest Payment Date.

Interest on the Notes shall be payable to the Persons in whose names the relevant Notes are registered at the close of business on the fifteenth calendar day preceding each Floating Rate Period Interest Payment Date or Fixed Rate Period Interest Payment Date, as applicable, whether or not a Business Day.

In the event that the Maturity Date or date of redemption, or repayment of any Note falls on a day that is not a Business Day, then the related payments of principal, premium, if any, and interest may be made on the next succeeding day that is a Business Day, but interest on that payment will not accrue during the period from and after the Maturity Date or date of redemption or repayment of any Note. If a date of redemption or repayment of any Note falls within the Floating Rate Period but does not occur on a Floating Rate Period Interest Payment Date, (i) the related Interest Determination Date shall be deemed to be the date that is two U.S. Government Securities Business Days prior to such date of redemption or repayment, (ii) the related Observation Period shall be deemed to end on (and exclude) the second U.S. Government Securities Business Day falling prior to such date of redemption or repayment, (iii) the Floating Rate Interest Period will be deemed to be shortened accordingly and (iv) corresponding adjustments will be deemed to be made to the Compounded SOFR Index Rate formula (or applicable Benchmark). Interest due on the Maturity Date of any Notes will be paid to the Person to whom principal of such Notes is payable.

If SOFR IndexStart or SOFR IndexEnd is not published on the relevant Interest Determination Date and a Benchmark Transition Event and its related Benchmark Replacement Date have not occurred with respect to SOFR, “Compounded SOFR Index Rate” shall mean, for the relevant 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 such successor website). 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 the daily 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.

A-4

In the event that the Company or its designee (in consultation with the Company) determines that a Benchmark Transition Event and related Benchmark Replacement Date have occurred prior to the applicable Reference Time in respect of any determination of the Benchmark on any date, the applicable Benchmark Replacement shall replace the then-current Benchmark for all purposes relating to the Notes during the Floating Rate Period in respect of such determination on such date and all determinations on all subsequent dates; provided that, if the Company or its designee (in consultation with the Company) is unable to or does not determine a Benchmark Replacement in accordance with the provisions below prior to 5:00 p.m. (New York time) on the relevant Interest Determination Date, the interest rate for the related Floating Rate Interest Period shall be equal to the interest rate in effect for the immediately preceding Floating Rate Interest Period or, in the case of the Interest Determination Date prior to the first Floating Rate Period Interest Payment Date, the Initial Interest Rate. In accordance with and subject to this Section 2.05(f), after a Benchmark Transition Event and related Benchmark Replacement Date have occurred, the amount of interest that will be payable for each interest period on the Notes during the Floating Rate Period will be determined by reference to a rate per annum equal to the Benchmark Replacement plus the Spread.

In connection with the implementation of a Benchmark Replacement, the Company or its designee (in consultation with the Company) shall have the right to make changes to (1) any Interest Determination Date, Floating Rate Period Interest Payment Date, Reference Time, Business Day convention or Floating Rate Interest Period, (2) the manner, timing and frequency of determining the rate and amounts of interest that are payable on the Notes during the Floating Rate Period and the conventions relating to such determination and calculations with respect to interest, (3) rounding conventions, (4) tenors and (5) any other terms or provisions of the Notes during the Floating Rate Period, in each case that the Company or its designee (in consultation with the Company) determines, from time to time, to be appropriate to reflect the determination and implementation of such Benchmark Replacement in a manner substantially consistent with market practice (or, if the Company or its designee (in consultation with the Company) decides that implementation of any portion of such market practice is not administratively feasible or determine that no market practice for use of the Benchmark Replacement exists, in such other manner as the Company or its designee (in consultation with the Company) determines is appropriate (acting in good faith)) (the “Benchmark Replacement Conforming Changes”). Any Benchmark Replacement Conforming Changes shall apply to the Notes for all future Floating Rate Interest Periods.

The Company shall promptly give notice of the determination of the Benchmark Replacement, the Benchmark Replacement Adjustment and any Benchmark Replacement Conforming Changes to the Trustee, the Paying Agent, the Calculation Agent and the Holders of the Notes; provided that failure to provide such notice shall have no impact on the effectiveness of, or otherwise invalidate, any such determination.

All determinations, decisions, elections and any calculations made by the Company or its designee for the purposes of determining the Benchmark Replacement, the Benchmark Replacement Adjustment and any Benchmark Replacement Conforming Changes shall be conclusive and binding on the Holders of the Notes, the Company, the Calculation Agent, the Trustee and the Paying Agent, absent manifest error. If made by the Company’s designee, such determinations, decisions, elections and calculations shall be made after consulting with the

A-5

Company, and such designees shall not make any such determination, decision, election or calculation to which the Company objects. Notwithstanding anything to the contrary in this Indenture, any determinations, decisions, calculations or elections made in accordance with this provision shall become effective without consent from the Holders of the Notes or any other party.

Notwithstanding any other provision herein, no Benchmark Replacement shall be adopted, nor shall the applicable Benchmark Replacement Adjustment be applied, nor shall any Benchmark Replacement Conforming Changes be made, if in the Company’s determination, the same could reasonably be expected to prejudice the qualification of the Notes as eligible liabilities or loss absorbing capacity instruments for the purposes of the Relevant Rules.

Except as otherwise provided in the Indenture, any 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 Note (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 by the Trustee, with notice thereof to be given to Holders of Notes not less than 5 days prior to the Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any automated quotation system or securities exchange on which the Notes may be quoted or listed, and upon such notice as may be required by such system or exchange, all as more fully provided in the Indenture.

All terms used in this Note which are defined in the Indenture and not otherwise defined herein shall have the meanings assigned to them in the Indenture.

Payment of principal and interest shall be made at the Corporate Trust Office of the Trustee, or at such other office or agency of the Company as may be designated by the Company for such purpose in the Borough of Manhattan, The City of New York, in such coin or currency of the United States of America as at the time of payment is legal tender for the payment of public and private debts, by Dollar check drawn on, or transfer to, a Dollar account. Payments of interest on this Note may be made by Dollar check, drawn on a Dollar account, mailed to the address of the Person entitled thereto as such address shall appear in the Security Register, or, upon written application by the Holder to the Security Registrar setting forth wire instructions not later than the relevant Record Date, by transfer to a Dollar account.

Except as specifically provided herein and in the Indenture, the Company shall not be required to make any payment with respect to any tax, assessment or other governmental charge imposed by any government or any political subdivision or taxing authority thereof or therein.

Reference is hereby made to the further provisions of this Note 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 or an Authenticating Agent by the manual or electronic signature of one of their respective authorized signatories, this Note shall not be entitled to any benefit under the Base Indenture, the Fifth Supplemental Indenture or the Eighth Supplemental Indenture or be valid or obligatory for any purpose. The Company may execute this Note without a corporate seal.

“Treasury Rate” means, with respect to any redemption date, the yield determined by the Company in accordance with the following two paragraphs.

A-9

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 or any successor designation or publication 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.

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

A-10

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the Depositary’s procedures) at least 5 days but not more than 60 days before the redemption date to each Holder of the Notes to be redeemed. Each notice of redemption will state:

If any Notes are redeemed, the redemption price payable to the holder of any Notes called for redemption will be payable on the applicable redemption date against the surrender to the Company or its agent of any certificate(s) evidencing the Notes called for redemption. If money sufficient to pay the redemption price of, and any accrued interest on, the Notes (or portions thereof) to be redeemed on the redemption date is deposited with the Company’s paying agent on or before the redemption date and certain other conditions are satisfied, then on and after the redemption date, interest will cease to accrue on the Notes (or such portion thereof) called for redemption and such Notes will cease to be outstanding.

The Notes are not be subject to repayment at the option of any Holder at any time prior to maturity and are not entitled to any sinking fund.

The Notes are unsecured and rank equally with all of the Company’s other unsecured and unsubordinated indebtedness.

The Notes are issuable only in registered form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof.

The Company may, without consent of the holders of the Notes, increase the principal amount of the Notes by issuing additional securities in the future on the same terms and conditions as the Notes, except for any difference in the issue price and interest accrued prior to the date of issuance of the additional securities, and with the same CUSIP number as the Notes. The Notes and any additional Notes issued by the Company would rank equally and ratably and would be treated as a single series for all purposes under the Indenture.

In any case where the due date for the payment of the principal of or interest on any Note at any Place of Payment, as the case may be, is not a Business Day, then payment of principal or interest need not be made on or by such date at such place but may be made on or by the next succeeding Business Day, with the same force and effect as if made on the date for such payment, and no interest shall accrue on the amount so payable for the period after such date.

A-11

If an Event of Default shall occur and be continuing, the principal of all the Notes, together with accrued interest to the date of declaration, may be declared due and payable in the manner and with the effect provided in the Indenture.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Notes under the Indenture at any time by the Company and the Trustee with the written consent of the Holders of not less than a majority in principal amount of the Notes at the time Outstanding. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Notes at the time Outstanding, on behalf of the Holders of all the Notes, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued in exchange herefor or in lieu hereof whether or not notation of such consent or waiver is made upon this Note or such other Note.

As provided in and subject to the provisions of the Indenture, the Holder of this Note shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default, the Holders of not less than 25% in principal amount of the Outstanding Notes shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee indemnity satisfactory to it and the Trustee shall not have received from the Holders of a majority in principal amount of the Outstanding Notes a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 20 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by any Holder of this Note for the enforcement of any payment of principal of or interest on this Note or after the respective due dates expressed herein.

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Note at the times, places and rate, and in the coin or currency, herein prescribed.

The Notes will be subject to defeasance and covenant defeasance pursuant to Sections 13.2 and 13.3 of the Base Indenture.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Note is registrable on the Security Register upon surrender of this Note for registration of transfer at the Corporate Trust Office of the Trustee or at such other office or agency of the Company as may be designated by it for such purpose in the Borough of Manhattan, The City of New York (which shall initially be an office or agency of the Trustee), or at such other offices or agencies as the Company may designate, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly

A-12

executed by, the Holder thereof or his attorney duly authorized in writing, and thereupon one or more new Securities, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees by the Security Registrar. No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to recover any tax or other governmental charge payable in connection therewith.

Prior to due presentation of this Note for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Note is registered, as the owner thereof for all purposes, whether or not such Note be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

No recourse for the payment of the principal of or interest on this Note and no recourse under or upon any obligation, covenant or agreement of the Company in the Indenture or any indenture supplemental thereto or in any Note, or because of the creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder, employee, agent, officer or director or subsidiary, as such, past, present or future, of the Company or of any successor corporation, either directly or through the Company or any successor corporation, whether by virtue of any constitution, statute or rule of law or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of consideration for the issue hereof, expressly waived and released.

THE NOTE SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

All capitalized terms used in this Note which are defined in the Indenture, and not otherwise defined herein, shall have the meanings assigned to them in the Indenture.

This definition of the Senior Debt shall supersede any conflicting provisions contained in Article 1.1 of the Base Indenture.

“Tax Event” shall mean the receipt by the Company of an opinion of independent tax counsel to the effect that as a result of:

ARTICLE II

GENERAL TERMS AND CONDITIONS OF THE NOTES

SECTION 2.01 Designation and Principal Amount. The Notes may be issued from time to time upon written order of the Company for the authentication and delivery of Notes pursuant to Section 3.3 of the Base Indenture. There is hereby authorized a series of Securities designated as the 6.141% Fixed-to-Fixed Rate Subordinated Notes due 2039 having an initial aggregate principal amount of $600,000,000.

SECTION 2.02 Maturity. The date upon which the Notes shall become due and payable at final maturity, together with any accrued and unpaid interest, is November 18, 2039 (the “Maturity Date”).

SECTION 2.03 Form, Payment and Appointment. Except as provided in the last three paragraphs of Section 3.5 of the Base Indenture, the Notes will be issued only in book-entry form. Principal of and interest on the Notes will be payable in global form registered in the name of or held by The Depository Trust Company (“DTC”) or its nominee in immediately available funds to DTC or its nominee, as the case may be, as the registered holder of such Global Note (as hereafter defined). The principal of and interest on any certificated Notes will be payable at the office or agency of the Company maintained for such purpose in Columbus, Ohio; provided, however, that payment of interest may be made at the option of the Company by check mailed to

5

the Person entitled thereto at such address as shall appear in the Security Register or by wire transfer to an account appropriately designated by the Person entitled to payment; provided that the paying agent shall have received written notice of such account designation at least five Business Days prior to the date of such payment (subject to surrender of the relevant Note in the case of a payment of interest on the Maturity Date).

The Security Registrar and Paying Agent for the Notes shall initially be the Trustee.

The Notes will be issuable and may be transferred only in denominations of $2,000 or any amount in excess thereof that is an integral multiple of $1,000. The specified currency of the Notes shall be U.S. Dollars.

SECTION 2.04 Global Note. The Notes shall be issued initially in the form of one or more fully registered global notes (each such global note, a “Global Note”) deposited with DTC or its designated custodian or such other Depositary as any officer of the Company may from time to time designate. Unless and until a Global Note is exchanged for Notes in certificated form, such Global Note may be transferred, in whole but not in part, and any payments on the Notes shall be made, only to DTC or a nominee of DTC, or to a successor Depositary selected or approved by the Company or to a nominee of such successor Depositary.

SECTION 2.05 Interest.

(a) The Notes will bear interest (i) during the period from and including the Issue Date, to, but excluding, the Reset Date, or to, but excluding, the date of earlier redemption, at a fixed rate of 6.141% per annum and (ii) during the period from and including the Reset Date, to, but excluding, the Maturity Date, or to, but excluding, the date of earlier redemption, at a rate per annum that will be the Five-year U.S. Treasury Rate as of the Reset Determination Date, plus 1.700% per annum. Interest on the Notes shall be payable semi-annually in arrears on May 18 and November 18 of each year (each, an “Interest Payment Date”), commencing May 18, 2025, to the Persons in whose names the relevant Notes are registered at the close of business on the Record Date, whether or not a Business Day, immediately preceding the applicable Interest Payment Date, except as provided in Section 2.05(c) and Section 2.05(d).

(b) Interest payable on any Interest Payment Date or the Maturity Date with respect to the Notes shall be the amount of interest accrued from, and including, the immediately preceding Interest Payment Date in respect of which interest has been paid or duly provided for (or from and including the original issue date of November 18, 2024, if no interest has been paid or duly provided for with respect to the Notes) to, but excluding, such Interest Payment Date or Maturity Date as the case may be (each, an “Interest Period”).

(c) Interest shall be computed on the basis of a 360-day year consisting of twelve 30-day months. If any scheduled Interest Payment Date falls on a day that is not a Business Day, the Company shall postpone the interest payment to the next succeeding Business Day, but the payment made on such date will be treated as having been made on the date that the payment was first due, and the holders of the Notes will not be entitled to any further interest or other payments with respect to such postponement.

6

(d) In the event that the Maturity Date for any Note falls on a day that is not a Business Day, then the related payments of principal, premium, if any, and interest may be made on the next succeeding day that is a Business Day (and no additional interest will accumulate on the amount payable for the period from and after the Maturity Date). Interest due on the Maturity Date (whether or not an Interest Payment Date) of any Notes will be paid to the Person to whom principal of such Notes is payable.

(e) The Company shall be responsible for making calculations called for under the Indenture and the Notes, including but not limited to determination of interest, Redemption Price (as defined herein), premium, if any, and any other amounts payable on the Notes. The Company shall make the calculations in good faith and, absent manifest error, its calculations will be final and binding on the holders of the Notes. The Company shall provide a schedule of its calculations to the Trustee when requested by the Trustee, and the Trustee is entitled to rely conclusively on the accuracy of the Company’s calculations without independent verification. The Trustee shall forward the Company’s calculations to any holder of the Notes upon the written request of such holder. Neither the Trustee nor the paying agent, acting in any capacity hereunder, shall have no liability or responsibility for making any calculation called for under this Third Supplemental Indenture or the Notes or for any information in connection with such calculations, and shall be entitled to rely conclusively upon the accuracy of the Company’s calculations without independent verification thereof.

(f) Unless the Company has delivered a notice of redemption for all outstanding Notes, with such redemption to occur on the Reset Date, the Company shall appoint a calculation agent with respect to the Notes prior to the Reset Determination Date, which calculation agent may be the Company or an Affiliate of the Company. The Five-year U.S. Treasury Rate will be determined by the calculation agent on the Reset Determination Date. The calculation agent will notify the Company within one Business Day of the interest rate from and after the Reset Date. The Company shall then promptly notify the Trustee in writing within five Business Days of such interest rate. Any determination, decision or election that may be made by the calculation agent hereunder, including any determination with respect to a rate, will be conclusive and binding absent manifest error, may be made in the calculation agent’s sole discretion, and, notwithstanding anything to the contrary herein, shall become effective without consent from any other party. The calculation agent’s determination of any interest rate will be on file at the Company’s principal offices, will be made available to any holder of the Notes upon request, and will be final and binding in the absence of manifest error. The Trustee or any Paying Agent will have no obligation to be named as calculation agent.

(g) For the avoidance of doubt, and notwithstanding anything herein to the contrary, the Trustee shall not at any time have any duty or responsibility to the Company, to the calculation agent, or any Holder to determine the Reset Date, the Reset Determination Date, the Five-year U.S. Treasury Rate (or any adjustment thereto) or whether any facts exist that may require any adjustment (including any increase) of any rate, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee is entitled to rely conclusively upon the accuracy of the Calculation Agent’s calculations, as notified to the Trustee by the Company, without independent verification.

SECTION 2.06 No Sinking Fund. The Notes are not entitled to the benefit of any sinking fund.

ARTICLE III

REDEMPTION OF THE NOTES

SECTION 3.01 Optional Redemption. On at least 5 days but no more than 60 days prior written notice delivered to the holders of the Notes, the Company may redeem the Notes in whole, but not in part, during the three months prior to and including the Reset Date, subject to obtaining the prior approval of the Federal Reserve to the extent such approval is then required under the rules of the Federal Reserve, at a redemption price equal to 100% of the aggregate principal amount of the Notes (the “Redemption Price”), plus accrued and unpaid interest thereon, if any, to, but excluding, the Redemption Date. The Company shall provide written notice to the Trustee of any redemption at least 15 days prior to the Redemption Date (unless a shorter notice is satisfactory to the Trustee). The Company may also redeem the Notes, in whole or in part, on or after May 18, 2039 (six months prior to the Maturity Date), at any time and from time to time, subject to obtaining the prior approval of the Federal Reserve to the extent such approval is then required under the rules of the Federal Reserve, 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.

(a) The Notes may not otherwise be redeemed prior to the Maturity Date, except that on at least 5 days but no more than 60 days prior written notice delivered to the holders of the Notes, the Company may also, at its option and subject to any prior required approval of the Federal Reserve to the extent such approval is then required under the rules of the Federal Reserve, redeem the Notes, in whole, but not in part, at a Redemption Price equal to 100% of the principal amount of the Notes plus accrued and unpaid interest to, but excluding, the Redemption Date, within 90 days of the occurrence of a Tax Event, Tier 2 Capital Event or a 1940 Act Event.

(b) The Company shall provide the notice to the holders of the Notes, referenced above in Sections 3.01(a) and 3.01(b), by first class mail, postage prepaid, or electronic transmission, addressed to the holders of the Notes (which, in the case of registered global Notes, will be DTC or its nominee or a nominee of Euroclear and Clearstream). Each such notice of redemption will state:

(i) the Redemption Date;

(ii) the Redemption Price;

(iii) “CUSIP” or “ISIN” number of the Notes;

(iv) that on the Redemption Date the Redemption Price will become due and payable upon each Note, and that interest thereon will cease to accrue on and after the Redemption Date; and

(v) the place or places where the Notes are to be surrendered for payment of the Redemption Price.

8

(c) Prior to giving any notice to the holders of the Notes pursuant to Section 3.01(b), the Company shall deliver to the Trustee an Opinion of Counsel and an Officers’ Certificate certifying that (i) a Tax Event, Tier 2 Capital Event or a 1940 Act Event has occurred and (ii) the Company is entitled to redeem the Notes in accordance with Section 3.01(b), and the Trustee may conclusively rely on such Opinion of Counsel and Officers’ Certificate.

(d) If the Company elects to have the Trustee deliver the notice of redemption on the Company’s behalf, then the Company shall have delivered to the Trustee no fewer than 15 days prior to the date such redemption notice is to be delivered (unless the Trustee agrees to a shorter period) an Officers’ Certificate providing such direction and setting forth the information to be stated in such notice as provided in Section 3.03 of the Base Indenture. The Company shall calculate the Redemption Price as described in the terms of the Notes and will deliver an Officers’ Certificate to the Trustee setting forth the Redemption Price and showing the calculation of such in reasonable detail no later than two Business Days prior to the Redemption Date, and the Trustee will not be responsible for such calculation nor shall the Trustee have any duty to monitor the accuracy of any calculations made by the Company, which will be conclusive and binding on the holders of the Notes, absent manifest error. The Notes are not subject to redemption or prepayment at the option of the holders of the Notes.

(e) In addition to the Company’s right to redeem the Notes as set forth above in this Section 3.01, the Company may at any time and from time to time purchase Notes in open market transactions, tender offers or otherwise, subject to the prior approval of the Federal Reserve, to the extent such approval is then required.

SECTION 3.02 Effect of Redemption. (a) Interest shall cease to accrue on the Notes on the Redemption Date, (b) the Notes shall become due and payable at the Redemption Price and (c) the Notes shall be void and all rights of the holders of the Notes in respect of the Notes shall terminate and lapse (other than the right to receive the Redemption Price upon surrender of such Notes but without interest on such Redemption Price).

SECTION 3.03 Redemption Procedures. On or prior to 11:00 a.m. New York City time on the Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust) an amount of money sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) accrued interest on, all the Notes that are to be redeemed on that date. If the Company gives an irrevocable notice of redemption with respect to the Notes pursuant to Section 3.01 of this Third Supplemental Indenture in connection with an optional redemption, and the Company has deposited with the Trustee or with the Paying Agent the Redemption Price of the Notes to be redeemed, then, on the Redemption Date, the Paying Agent shall irrevocably deposit such funds with the Depository. The Company shall also give the Trustee irrevocable instructions and authority to instruct the Depository to pay the Redemption Price in immediately available funds to the holders of beneficial interests in the Global Notes. If any Redemption Date is not a Business Day, then the Redemption Price shall be payable on the next Business Day (and without any interest or other payment in respect of any such delay). Interest to be paid on or before the Redemption Date for any Notes called for redemption shall be payable to the Holders on the Record Date for the related Interest Payment Dates. If any Notes called for redemption are not so paid upon surrender thereof for redemption, the Redemption Price shall, until paid, bear interest from the Redemption Date at the Coupon Rate then in effect.

SECTION 3.04 No Other Redemption. Except as set forth in this Article III, the Notes shall not be redeemable by the Company prior to the Maturity Date.

(a) Delivery to the Trustee of any reports, information and documents pursuant to the Base Indenture is for informational purposes only and the Trustee’s receipt of such reports, information and documents shall not constitute actual or constructive notice or knowledge of any information contained therein or determinable from information contained therein, including the compliance of the Company with any of its covenants in the Base Indenture and this Eighth Supplemental Indenture (as to which the Trustee is entitled to conclusively rely exclusively on Officers’ Certificates).

(b) The Trustee may request that the Company deliver an Officers’ Certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to the Base Indenture and this Eighth Supplemental Indenture, which Officers’ Certificate may be signed by any person authorized to sign an Officers’ Certificate, including any person specified as so authorized in any such certificate previously delivered and not superseded.

(e) The Trustee agrees to accept and act upon instructions or directions pursuant to this Indenture sent by unsecured e-mail, pdf, facsimile transmission or other similar unsecured electronic methods, provided, however, that the Trustee shall have received an incumbency certificate listing persons designated to give such instructions or directions and containing specimen signatures of such designated persons, which such incumbency certificate shall be amended and replaced whenever a person is to be added or deleted from the listing. If the Company elects to give the Trustee e-mail or facsimile instructions (or instructions by a similar electronic

13

method) and the Trustee in its discretion elects to act upon such instructions, the Trustee’s understanding of such instructions shall be deemed controlling. The Trustee shall not be liable for any losses, costs or expenses arising directly or indirectly from the Trustee’s reliance upon and compliance with such instructions notwithstanding that such instructions conflict or are inconsistent with a subsequent written instruction. The Company agrees to assume all risks arising out of the use of such electronic methods to submit instructions and directions to the Trustee, including, without limitation, the risk of the Trustee acting on unauthorized instructions, and the risk or interception and misuse by third parties.

(f) Facsimile, documents executed, scanned and transmitted electronically and electronic signatures, including those created or transmitted through a software platform or application, shall be deemed original signatures for purposes of this Indenture and all matters and agreements related thereto, with such facsimile, scanned and electronic signatures having the same legal effect as original signatures. The parties agree that this Indenture or any instrument, agreement or document necessary for the consummation of the transactions contemplated by this Indenture or related hereto or thereto (including, without limitation, addendums, amendments, notices, instructions, communications with respect to the delivery of securities or the wire transfer of funds or other communications) (“Executed Documentation”) may be accepted, executed or agreed to through the use of an electronic signature in accordance with applicable laws, rules and regulations in effect from time to time applicable to the effectiveness and enforceability of electronic signatures. Any Executed Documentation accepted, executed or agreed to in conformity with such laws, rules and regulations will be binding on all parties hereto to the same extent as if it were physically executed and each party hereby consents to the use of any third party electronic signature capture service providers as may be reasonably chosen by a signatory hereto or thereto. When the Trustee acts on any Executed Documentation sent by electronic transmission, the Trustee will not be responsible or liable for any losses, costs or expenses arising directly or indirectly from its reliance upon and compliance with such Executed Documentation, notwithstanding that such Executed Documentation (a) may not be an authorized or authentic communication of the party involved or in the form such party sent or intended to send (whether due to fraud, distortion or otherwise) or (b) may conflict with, or be inconsistent with, a subsequent written instruction or communication; it being understood and agreed that the Trustee shall conclusively presume that Executed Documentation that purports to have been sent by an authorized officer of a Person has been sent by an authorized officer of such Person. The party providing Executed Documentation through electronic transmission or otherwise with electronic signatures agrees to assume all risks arising out of such electronic methods, including, without limitation, the risk of the Trustee acting on unauthorized instructions and the risk of interception and misuse by third parties.

(g) The Trustee shall not be liable for any loss or liability resulting from force majeure, which shall be deemed to include any circumstances beyond its reasonable control (including, but not limited to, any act or provision of any present or future law or regulation or governmental authority, any act of God or war, civil unrest, local or national disturbance or disaster, pandemic, epidemic, any act of terrorism or the unavailability of the U.S. Federal Reserve Bank wire or any facsimile or other wire or communication facility), it being understood that the Trustee shall use reasonable efforts that are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances.

HUNTINGTON BANCSHARES INCORPORATED, a Maryland corporation (herein called the “Company”, which term includes any successor Person under the Indenture referred to on the reverse hereof), for value received, hereby promises to pay to Cede & Co., or its registered assigns, the principal sum of [five hundred] [one hundred] million United States dollars on November 18, 2039 and all accrued and unpaid interest thereon on November 18, 2039, or if such day is not a Business Day, the following Business Day.

The Company further promises to pay interest as follows. During the period from (and including) November 18, 2024, to (but excluding) November 18, 2034, the Notes will bear interest at the rate of 6.141% per annum. Such interest will be payable semi-annually in arrears on each May 18 and November 18 of each year, beginning on May 18, 2025 and ending on November 18, 2034. During the period from (and including) November 18, 2034, to (but excluding) the Maturity Date, the Notes will bear interest at a rate per annum that will be the Five-year U.S. Treasury Rate as of the day falling two Business Days prior to November 18, 2034, plus 1.700% per annum.

If any scheduled interest payment date is not a Business Day, any payment of principal and interest on the Notes will be postponed to the next day that is a Business Day, but the payment made on such date will be treated as having been made on the date that the payment was first due and the holders of the subordinated notes will not be entitled to any further interest or other payments with respect to such postponement.

Interest on the Notes shall be payable to the Persons in whose names the relevant Notes are registered at the close of business on the fifteenth calendar day preceding each Floating Rate Period Interest Payment Date or Fixed Rate Period Interest Payment Date, as applicable, whether or not a Business Day.

In the event that the Maturity Date or date of redemption, or repayment of any Note falls on a day that is not a Business Day, then the related payments of principal, premium, if any, and interest may be made on the next succeeding day that is a Business Day, but interest on that payment will not accrue during the period from and after the Maturity Date or date of redemption or repayment of any Note. Interest due on the Maturity Date of any Notes will be paid to the Person to whom principal of such Notes is payable.

Except as otherwise provided in the Indenture, any 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 Note (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 by the Trustee, with notice thereof to be given to Holders of Notes not less than 5 days prior to the Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any automated quotation system or securities exchange on which the Notes may be quoted or listed, and upon such notice as may be required by such system or exchange, all as more fully provided in the Indenture.

All terms used in this Note which are defined in the Indenture and not otherwise defined herein shall have the meanings assigned to them in the Indenture.

Payment of principal and interest shall be made at the Corporate Trust Office of the Trustee, or at such other office or agency of the Company as may be designated by the Company for such purpose in the Borough of Manhattan, The City of New York, in such coin or currency of the United States of America as at the time of payment is legal tender for the payment of public and private debts, by Dollar check drawn on, or transfer to, a Dollar account.

[FORM OF REVERSE SIDE OF THE NOTE]

This Note is one of a duly authorized issue of subordinated debt securities of the Company designated as its “6.141% Fixed-to-Fixed Rate Subordinated Notes due 2039” (the “Notes”). The Notes, taken together, are initially limited in aggregate principal amount to U.S. $600,000,000 issued and are to be issued under an Indenture, dated as of December 29, 2005 (herein called the “Base Indenture”), between the Company and The Bank of New York Mellon Trust Company, N.A., as Trustee (the “Trustee”, which term includes any successor trustee under the Base Indenture), as amended and supplemented by the Third Supplemental Indenture, dated as of November 18, 2024, between the Company and the Trustee (the “Third Supplemental Indenture”); the Base Indenture, as amended and supplemented by the Third Supplemental Indenture, the “Indenture”), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered. As provided in the Indenture and subject to certain limitations therein set forth, Notes are exchangeable for a like aggregate principal amount of Notes of any authorized denominations as requested by the Holder surrendering the same upon surrender of the Note or Notes to be exchanged, at the Corporate Trust Office of the Trustee. The Trustee upon such surrender by the Holder will issue the new Notes in the requested denominations.

Amounts owed to the Trustee in connection with the Notes will not be treated as subordinated indebtedness.

On at least 5 days but no more than 60 days prior written notice delivered to the holders of the Notes, the Company may redeem the Notes in whole, but not in part, during the three months prior to and including the Reset Date, subject to obtaining the prior approval of the Federal Reserve to the extent such approval is then required under the rules of the Federal Reserve, 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. The Company shall provide written notice to the Trustee of any redemption at least 15 days prior to the Redemption Date (unless a shorter notice is satisfactory to the Trustee). The Company may also redeem the Notes, in whole or in part, on or after May 18, 2039 (six months prior to the Maturity Date), at any time and from time to time, subject to obtaining the prior approval of the Federal Reserve to the extent such approval is then required under the rules of the Federal Reserve, 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.

The Notes may not otherwise be redeemed prior to the Maturity Date, except that on at least 5 days but no more than 60 days prior written notice delivered to the holders of the Notes, the Company may also, at its option and subject to any prior required approval of the Federal Reserve to the extent such approval is then required under the rules of the Federal Reserve, redeem the Notes, in whole, but not in part, at a Redemption Price equal to 100% of the principal amount of the Notes plus accrued and unpaid interest to, but excluding, the Redemption Date, within 90 days of the occurrence of a Tax Event, Tier 2 Capital Event or a 1940 Act Event.

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

A-4

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the Depositary’s procedures) at least 5 days but not more than 60 days before the redemption date to each Holder of the Notes to be redeemed. Each notice of redemption will state:

If any Notes are redeemed, the redemption price payable to the holder of any Notes called for redemption will be payable on the applicable redemption date against the surrender to the Company or its agent of any certificate(s) evidencing the Notes called for redemption. If money sufficient to pay the redemption price of, and any accrued interest on, the Notes (or portions thereof) to be redeemed on the redemption date is deposited with the Company’s paying agent on or before the redemption date and certain other conditions are satisfied, then on and after the redemption date, interest will cease to accrue on the Notes (or such portion thereof) called for redemption and such Notes will cease to be outstanding.

The Notes are not be subject to repayment at the option of any Holder at any time prior to maturity and are not entitled to any sinking fund.

The Notes are unsecured and rank equally with all of the Company’s other unsecured and unsubordinated indebtedness.

The Notes are issuable only in registered form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof.

The Company may, without consent of the holders of the Notes, increase the principal amount of the Notes by issuing additional securities in the future on the same terms and conditions as the Notes, except for any difference in the issue price and interest accrued prior to the date of issuance of the additional securities, and with the same CUSIP number as the Notes. The Notes and any additional Notes issued by the Company would rank equally and ratably and would be treated as a single series for all purposes under the Indenture.

A-5

In any case where the due date for the payment of the principal of or interest on any Note at any Place of Payment, as the case may be, is not a Business Day, then payment of principal or interest need not be made on or by such date at such place but may be made on or by the next succeeding Business Day, with the same force and effect as if made on the date for such payment, and no interest shall accrue on the amount so payable for the period after such date.

If an Event of Default shall occur and be continuing, the principal of all the Notes, together with accrued interest to the date of declaration, may be declared due and payable in the manner and with the effect provided in the Indenture.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Notes under the Indenture at any time by the Company and the Trustee with the written consent of the Holders of not less than a majority in principal amount of the Notes at the time Outstanding. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Notes at the time Outstanding, on behalf of the Holders of all the Notes, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued in exchange herefor or in lieu hereof whether or not notation of such consent or waiver is made upon this Note or such other Note.

As provided in and subject to the provisions of the Indenture, the Holder of this Note shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default, the Holders of not less than 25% in principal amount of the Outstanding Notes shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee indemnity satisfactory to it and the Trustee shall not have received from the Holders of a majority in principal amount of the Outstanding Notes a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 20 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by any Holder of this Note for the enforcement of any payment of principal of or interest on this Note or after the respective due dates expressed herein.

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Note at the times, places and rate, and in the coin or currency, herein prescribed.

The Notes will be subject to defeasance and covenant defeasance pursuant to Sections 13.2 and 13.3 of the Base Indenture.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Note is registrable on the Security Register upon surrender of this Note for registration of transfer at the Corporate Trust Office of the Trustee or at such other office or agency of the Company as may be designated by it for such purpose in the Borough of Manhattan, The City of

A-6

New York (which shall initially be an office or agency of the Trustee), or at such other offices or agencies as the Company may designate, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder thereof or his attorney duly authorized in writing, and thereupon one or more new Securities, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees by the Security Registrar.

Exhibit 5.2

[Letterhead of Wachtell, Lipton, Rosen & Katz]

November 18, 2024

Huntington Bancshares Incorporated

41 South High Street

Columbus, Ohio 43287

Ladies and Gentlemen:

We have acted as special counsel to Huntington Bancshares Incorporated, a Maryland corporation (the “Company”), in connection with the offering and sale by the Company of $1,150,000,000 aggregate principal amount of its 5.272% Fixed-to-Floating Rate Senior Notes due 2031 (the “Senior Notes”) and $600,000,000 aggregate principal amount of its 6.141% Fixed-to-Fixed Rate Subordinated Notes due 2039 (the “Subordinated Notes,” and together with the Senior Notes, the “Notes”) in an underwritten registered public offering, pursuant to the underwriting agreement (the “Underwriting Agreement”), dated November 12, 2024, by and among the Company and, on behalf of themselves and the several underwriters named therein, Citigroup Global Markets Inc., Goldman Sachs & Co. LLC, Huntington Securities, Inc., RBC Capital Markets, LLC and UBS Securities LLC. The Senior Notes are to be issued under a Senior Debt Securities Indenture (the “Base Senior Indenture”), dated as of December 29, 2005, between the Company and The Bank of New York Mellon Trust Company, N.A. (successor to The Bank of New York Mellon and JPMorgan Chase Bank, N.A.) (the “Trustee”), as amended and supplemented by a Fifth Supplemental Indenture, dated as of August 21, 2023, between the Company and the Trustee (the “Fifth Supplemental Indenture”) and an Eighth Supplemental Indenture, dated as of November 18, 2024, between the Company and the Trustee (the “Eighth Supplemental Indenture,” and together with the Fifth Supplemental Indenture and the Base Senior Indenture, the “Senior Indenture”). The Subordinated Notes are to be issued under a Subordinated Debt Securities Indenture (the “Base Subordinated Indenture”), dated as of December 29, 2005, between the Company and the Trustee, as supplemented by a Third Supplemental Indenture, dated as of November 18, 2024 (the “Third Supplemental Indenture,” and together with the Base Subordinated Indenture, the “Subordinated Indenture”).

In connection with the opinion set forth herein, we have examined and relied on originals or copies, certified or otherwise, identified to our satisfaction, of such documents, corporate records, agreements, certificates, and other instruments and such matters of law, in each case, as we have deemed necessary or appropriate for the purposes of this opinion, including the Base Senior Indenture, the Base Subordinated Indenture, forms of the Notes, the Fifth Supplemental Indenture, the Eighth Supplemental Indenture and the Third Supplemental Indenture, which we refer to herein as the “Transaction Documents.” We have also conducted such investigations of fact and law as we have deemed necessary or advisable for purposes of this opinion. In such examination, we have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to authentic original documents of all documents submitted to us as copies and the legal capacity of all individuals executing such documents. We have also assumed the valid authorization, execution and delivery of each of the Transaction Documents by each party thereto other than the Company, and we have assumed that each such other party (in the case of parties which are not natural persons) has been duly

organized and is validly existing and in good standing under its jurisdiction of organization, that each such other party has the legal capacity, power and authority to perform its obligations thereunder and that each of the Transaction Documents constitutes the valid and binding obligation of all such other parties, enforceable against them in accordance with its terms.

We are members of the Bar of the State of New York, and this opinion is limited to the federal securities laws of the United States of America and the laws of the State of New York, in each case as in effect on the date hereof. We have not considered, and we express no opinion or belief as to matters of the laws of any other jurisdiction or as to any matters arising thereunder or relating thereto.

Based upon the foregoing and subject to the qualifications, assumptions and limitations stated herein, we are of the opinion that the Notes, when authenticated and issued in accordance with the terms of the applicable Indenture and delivered against payment therefor as set forth in the Underwriting Agreement, will constitute valid and legally binding obligations of the Company enforceable against the Company in accordance with their terms.

The opinion set forth above is subject to the effects of (a) bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other similar laws relating to or affecting the enforcement of creditors’ rights generally, (b) general equitable principles (whether considered in a proceeding in equity or at law), and (c) an implied covenant of good faith and fair dealing. We express no opinion as to whether, or the extent to which, the laws of any particular jurisdiction apply to the subject matter hereof, including, without limitation, the enforceability of the governing law provision contained in the Notes or their governing documents or in any other agreement.

We consent to the filing of a copy of this opinion as an exhibit to a report on Form 8-K to be filed by the Company on the date hereof and its incorporation by reference into the Registration Statement on Form S-3ASR (File No. 333-263546) (the “Registration Statement”). In addition, we consent to references to us in the prospectus forming a part of the Registration Statement under the heading “Validity of the Notes.” In giving this consent, we do not thereby admit that we are within the category of persons whose consent is required under Section 7 of the Securities Act of 1933, as amended, and the rules and regulations thereunder. This opinion speaks as of its date, and we undertake no (and hereby disclaim any) obligation to update this opinion.
