Ladies and Gentlemen:

Fifth Third Bancorp, an Ohio corporation (the “Company”), proposes to issue and sell to the several Underwriters listed in Schedule 1 hereto (the “Underwriters”), for whom you are acting as representatives (the “Representatives”) $750,000,000 principal amount of its 4.895% Fixed Rate/Floating Rate Senior Notes due 2030 having the terms set forth in Schedule 2 hereto (the “Securities”). The Securities will be issued pursuant to an indenture dated as of April 30, 2008, as amended to date, and as such indenture may hereafter be amended and supplemented (the “Indenture”), between the Company and Wilmington Trust Company, as trustee (the “Trustee”).

The Company agrees to issue and sell the Securities to the several Underwriters as provided in this Agreement, and each Underwriter, on the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth herein, agrees, severally and not jointly, to purchase from the Company the respective principal amount of Securities set forth opposite such Underwriter’s name in Schedule 1 hereto at a price equal to 99.650% of the principal amount of the Securities, plus accrued interest, if any, from September 6, 2024 (the “Purchase Price”). The Company will not be obligated to deliver any of the Securities except upon payment for all the Securities to be purchased as provided herein. To the extent there are no additional Underwriters named in Schedule 1 hereto other than you, the term Representatives as used herein shall mean you, as Underwriters, and the terms Representatives and Underwriters shall mean either the singular or plural as the context requires.

The Company understands that the Underwriters intend to make a public offering of the Securities as soon after the effectiveness of this Agreement as in the judgment of the Representatives is advisable, and initially to offer the Securities on the terms set forth in the Time of Sale Information and the Prospectus. Schedule 3 hereto sets forth the Time of Sale Information made available at the Time of Sale. The Company acknowledges and agrees that the Underwriters may offer and sell Securities to or through any affiliate of an Underwriter and that any such affiliate may offer and sell Securities purchased by it to or through any Underwriter.

The Company further acknowledges that the only information furnished to the Company by the Representatives for purposes of Sections 3(a), 3(b), 3(c), 7(a) and 7(b) of the Underwriting Agreement Standard Provisions are set forth in Schedule 5 hereto.

Payment for and delivery of the Securities shall be made at the offices of Davis Polk & Wardwell LLP, 450 Lexington Avenue, New York, New York 10017, at 9:00 A.M., New York City time, on September 6, 2024, or at such other time or place on the same or such other date, not later than the fifth business day thereafter, as the Representatives and the Company may agree upon in writing (the “Closing Date”).

Payment for the Securities shall be made by wire transfer in immediately available funds to the account(s) specified by the Company to the Representatives against delivery of one or more global notes representing the Securities (collectively, the “Global Note”) to the nominee of The Depository Trust Company, for the account of the Underwriters, with any transfer taxes payable in connection with the sale of the Securities duly paid by the Company. The Global Note will be made available to the Representatives for inspection not later than 1:00 P.M., New York City time, on the business day prior to the Closing Date.

All provisions contained in the document entitled Underwriting Agreement Standard Provisions attached as Exhibit A hereto are incorporated by reference herein in their entirety and shall be deemed to be a part of this Underwriting Agreement to the same extent as if such provisions had been set forth in full herein, except that if any term defined in such Underwriting Agreement Standard Provisions is otherwise defined herein, the definition set forth herein shall control. With respect to the Securities, the Time of Sale referred to in the Standard Provisions is 3:30 P.M., New York City time, on September 3, 2024.

This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same Agreement. The words “execution,” “signed,” “signature,” “delivery” and words of like import in or relating to this Agreement or any document to be signed in connection with this Agreement shall be deemed to include electronic signatures complying with the U.S. federal ESIGN Act of 2000 or the New York Electronic Signature and Records Act or deliveries or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature, physical delivery thereof or the use of a paper-based recordkeeping system, as the case may be, and the parties hereto consent to conduct the transactions contemplated hereunder by electronic means.

September 6, 2024

As counsel for the Company, we have examined the Company Organizational Documents (as hereinafter defined) and the Underwriting Agreement.

We have assumed that each document and certificate submitted to us for review is accurate and complete, each such document or certificate that is an original is authentic, each such document or certificate that is a copy conforms to an authentic original, and all signatures on each such document or certificate are genuine. We have also assumed that each party to the Underwriting Agreement (other than the Company) has satisfied those legal requirements that are applicable to it to the extent necessary to make such agreement enforceable against it.

We have further assumed that all parties have acted and will act in good faith, without fraud, duress, undue influence, or a lack of conscionability or fair dealing.

With respect to applicable law, we have assumed the constitutionality of all relevant law and the general availability of all relevant decisions, rules and regulations to lawyers practicing in the State of Ohio.

As to certain questions of fact relevant to our opinions herein, we have relied solely upon the accuracy of the representations and warranties set forth in the Underwriting Agreement and on certificates of officers of the Company, without independent investigation or other verification.

We have examined and are familiar with the Articles of Incorporation, as amended, and Code of Regulations, as amended, of the Company; and a Certificate of Good Standing issued by the Ohio Secretary of State on September 6, 2024 (collectively, the “Company Organizational Documents”).

Based on the foregoing as well as such other documents as we have deemed necessary to enable us to render this opinion, we are of the opinion that:

(1) The Company has been duly incorporated, is validly existing as a corporation in good standing under the laws of the State of Ohio, is duly registered as a bank holding company and qualified as a financial holding company under the Bank Holding Company Act of 1956, as amended. The Company has the corporate power and authority to own, lease and operate its property and to conduct its business as described in each of the Registration Statement, the Prospectus and the Time of Sale Information and is duly qualified to transact business and is in good standing in each jurisdiction in which the conduct of its business or its ownership or leasing of property requires such qualification, except to the extent that the failure to be so qualified or to be in good standing would not have a material adverse effect on the current or future financial position, stockholders’ equity or results of operations of the Company and its subsidiaries, taken as a whole.

(2) The execution and delivery by the Company of, and the performance by the Company of its obligations under, the Underwriting Agreement will not contravene any provision of the articles of incorporation or code of regulations of the Company. To our knowledge, the execution and delivery by the Company of, and the performance by the Company of its obligations under, the Underwriting Agreement will not contravene (a) any applicable law, (b) any agreement or other instrument binding upon the Company or any of its Significant Subsidiaries, or (c) any judgment, order or decree of any governmental body, agency or court having jurisdiction over the Company or any Significant Subsidiary, except, in the case of clauses (a), (b) and (c) above, that would not have a material adverse effect on the current or future financial position, stockholders’ equity or results of operation of the Company and its subsidiaries, taken as a whole, and no consent, approval, authorization or order of, or qualification with, any governmental body or agency is required for the performance by the Company of its obligations under the Underwriting Agreement, except such as have been obtained under the Securities Act or may be required by the securities or Blue Sky laws of the various states in connection with the offer and sale of the Notes.

(3) To our knowledge, there are no current or pending legal, governmental or regulatory actions, suits or proceedings that are required under the Securities Act to be described in the Registration Statement, the Time of Sale Information or the Prospectus and that are not so described in the Registration Statement, the Time of Sale Information and the Prospectus.

(4) The Notes conform as to legal matters to the description thereof contained in each of the Registration Statement, the Prospectus and the Time of Sale Information.

(5) The Indenture has been duly authorized, executed and delivered by the Company and, assuming due execution and delivery thereof by the Trustee, constitutes a valid and legally binding agreement of the Company enforceable against the Company in accordance with its terms.

(6) The Notes have been duly authorized, executed and delivered by the Company and, when duly authenticated as provided in the Indenture and paid for as provided in the Underwriting Agreement, will be duly and validly issued and outstanding and will constitute valid and legally binding obligations of the Company enforceable against the Company in accordance with their terms, and will be entitled to the benefits of the Indenture.

(7) The authorized capital stock of the Company conforms as to legal matters to the description thereof contained in each of the Registration Statement, the Prospectus and the Time of Sale Information.

(8) The Underwriting Agreement has been duly authorized, executed and delivered by the Company.

(9) The Company is not, and after giving effect to the offering and sale of the Notes and the application of the proceeds thereof as described in the Time of Sale Information, the Company will not be, required to register as an “investment company” as such term is defined in the Investment Company Act of 1940, as amended.

This letter deals only with the specific legal issues it explicitly addresses. Accordingly, an express opinion concerning a particular legal issue does not address any other matters. An express opinion includes an implied opinion only if it is both essential to the legal conclusion reached by the express opinion and, based upon prevailing norms and expectations among experienced lawyers in the State of Ohio, reasonable in the circumstances. Further, we do not opine as to the effect of state securities, antitrust, intellectual property, environmental, tax, criminal or local law (except to the extent of our opinion with respect to statements in the Preliminary Prospectus and the Prospectus under the headings “Certain U.S. Federal Income Tax Consequences” and “Description of the Notes” contained in our disclosure letter delivered to you on the date hereof).

The addressees may not rely on this letter or this firm for any legal or other analysis beyond that set forth in this letter, such as the broader guidance and counsel that we might provide to the Company.

This letter speaks only as of its date. We have no obligation to advise the addressees (or any third party) of changes of law or fact that occur after the date of this letter, regardless of whether the change may affect the legal analysis, a legal conclusion or an informational confirmation in this letter.

Our opinions contained in numbered paragraphs (5) and (6) as to enforceability are subject to the further qualifications that such enforceability may be: (A) limited by bankruptcy, insolvency (including, without limitation, fraudulent conveyances and fraudulent transfers); reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally; (B) subject to the exercise of judicial discretion in accordance with general principles of equity (whether applied by a court of law or equity); (C) limited by general equitable principles, including, without limitation, concepts of materiality, reasonableness, good faith and fair dealing (regardless of whether such enforceability is considered, in a proceeding in equity or at law); (D) subject to the effect of any public policy considerations; or (E) subject to the requirements of good faith, fair dealing, diligence and reasonableness.

Whenever this opinion refers to matters within our “knowledge,” such reference is limited to facts within the actual knowledge of the attorneys of our firm who have given substantive attention to the Company’s offering of the Notes or other material matters for the Company, after due inquiry.

We are licensed to practice in the State of Ohio. We express no opinion about the effect of the laws of any jurisdiction other than the laws of the State of Ohio and the Federal laws of the United States. As you know, certain of the documents provide that they will be governed by the laws of the State of New York. In rendering the opinion set forth herein we have relied with your permission on the legal opinion of Davis Polk & Wardwell LLP delivered pursuant to Section 6(h) of the Standard Provisions as to all matters concerning the applicability of New York law.

This letter is solely for the benefit of the addressees and may not be relied upon, nor may copies be delivered to, any other parties or persons without our prior written consent.

EXHIBIT A

FIFTH THIRD BANCORP

Underwriting Agreement Standard Provisions

From time to time, Fifth Third Bancorp, an Ohio corporation (the “Company”), may enter into one or more underwriting agreements that incorporate by reference these Standard Provisions (collectively with these Standard Provisions, an “Underwriting Agreement”) that provide for the sale of the securities designated in such Underwriting Agreement (the “Securities”) to the several Underwriters named therein (the “Underwriters”), for whom the Underwriter(s) named therein shall act as representative(s) (the “Representative(s)”). The Underwriting Agreement, including these Standard Provisions, is sometimes referred to herein as this “Agreement.” The Securities will be issued pursuant to an indenture dated as of April 30, 2008, as amended to date, and as such indenture may hereafter be supplemented (the “Indenture”), between the Company and Wilmington Trust Company, as trustee (the “Trustee”).

Section 1. Registration Statement. The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Securities Act”), a registration statement on Form S-3 (File No. 333-263894), including a prospectus (the “Basic Prospectus”), relating to certain securities to be issued from time to time by the Company. The Company has also filed, or proposes to file, with the Commission pursuant to Rule 424 under the Securities Act a prospectus supplement specifically relating to the Securities (the “Prospectus Supplement”). The registration statement, as amended at the time it becomes effective, including the information, if any, deemed pursuant to Rule 430A, 430B or 430C under the Securities Act to be part of the registration statement at the time of its effectiveness (“Rule 430 Information”), is referred to herein as the “Registration Statement”; and as used herein, the term “Prospectus” means the Basic Prospectus as supplemented by the prospectus supplement specifically relating to the Securities in the form first used (or made available upon request of purchasers pursuant to Rule 173 under the Securities Act) in connection with confirmation of sales of the Securities and the term “Preliminary Prospectus” means the preliminary prospectus supplement specifically relating to the Securities together with the Basic Prospectus. If the Company has filed an abbreviated registration statement pursuant to Rule 462(b) under the Securities Act (the “Rule 462 Registration Statement”), then any reference herein to the term “Registration Statement” shall be deemed to include such Rule 462 Registration Statement. Capitalized terms used but not defined herein shall have the meanings given to such terms in the Registration Statement and the Prospectus. References herein to the Registration Statement, the Basic Prospectus, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein. The terms “supplement,” “amendment” and “amend” as used herein with respect to the Registration Statement, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include any documents filed by the Company under the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission thereunder (the “Exchange Act”) subsequent to the date of the Underwriting Agreement which are deemed to be incorporated by reference therein. For purposes of this Agreement, the term “Effective Time” means the effective date of the Registration Statement with respect to the offering of Securities, as determined for the Company pursuant to Section 11 of the Securities Act and Item 512 of Regulation S-K, as applicable.

Exhibit A-1

At or prior to the time when sales of the Securities will be first made (the “Time of Sale”), the Company will prepare certain information (collectively, the “Time of Sale Information”) which information will be identified in Schedule 3 to the Underwriting Agreement for such offering of Securities as constituting part of the Time of Sale Information.

Section 2. Purchase of the Securities by the Underwriters. (a) The Company agrees to issue and sell the Securities to the several Underwriters named in the Underwriting Agreement, and each Underwriter, on the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth herein, agrees, severally and not jointly, to purchase from the Company the respective principal amount of Securities set forth opposite such Underwriter’s name in Schedule 1 to the Underwriting Agreement at the respective Purchase Price set forth in the Underwriting Agreement.

Exhibit A-10

Exhibit A-11

All opinions, letters, certificates and evidence mentioned above or elsewhere in this Agreement shall be deemed to be in compliance with the provisions hereof only if they are in form and substance reasonably satisfactory to counsel for the Underwriters.

Section 7. Indemnification and Contribution. (a) Indemnification of the Underwriters. The Company agrees to indemnify and hold harmless each Underwriter, its affiliates, directors and officers and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted as such fees and expenses are incurred), joint or several, that arise out of, or are based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein, not misleading, or (ii) any untrue statement or alleged untrue statement of a material fact contained in the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus or any Time of Sale Information, or caused by any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, in each case except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to any Underwriter furnished to the Company in writing by such Underwriter through the Representatives expressly for use therein.

Exhibit A-12

Exhibit A-13

Section 8. Termination. This Agreement may be terminated in the absolute discretion of the Representatives, by notice to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on the New York Stock Exchange, the NYSE American, the Nasdaq Stock Market, the Chicago Board Options Exchange, the Chicago Mercantile Exchange or the Chicago Board of Trade, or the over-the-counter market; (ii) trading of any securities issued or guaranteed

Exhibit A-14

by the Company shall have been suspended on any exchange or in any over-the-counter market; (iii) a general moratorium on commercial banking activities shall have been declared by federal or New York State authorities; or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States, that, in the judgment of the Representatives, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Securities on the terms and in the manner contemplated by this Agreement, the Time of Sale Information and the Prospectus.

Section 9. Defaulting Underwriter. (a) If, on the Closing Date, any Underwriter defaults on its obligation to purchase the Securities that it has agreed to purchase hereunder, the non-defaulting Underwriters may in their discretion arrange for the purchase of such Securities by other persons satisfactory to the Company on the terms contained in this Agreement. If, within 36 hours after any such default by any Underwriter, the non-defaulting Underwriters do not arrange for the purchase of such Securities, then the Company shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Underwriters to purchase such Securities on such terms. If other persons become obligated or agree to purchase the Securities of a defaulting Underwriter, either the non-defaulting Underwriters or the Company may postpone the Closing Date for up to five full business days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Underwriters may be necessary in the Registration Statement and the Prospectus or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Registration Statement and the Prospectus that effects any such changes. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in the Underwriting Agreement that, pursuant to this Section 9, purchases Securities that a defaulting Underwriter agreed but failed to purchase.

Exhibit A-15

Section 10. Payment of Expenses. (a) Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, the Company will pay or cause to be paid all costs and expenses incident to the performance of its obligations hereunder, including without limitation, (i) the costs incident to the authorization, issuance, sale, preparation and delivery of the Securities and any taxes payable in that connection; (ii) the costs incident to the preparation, printing and filing under the Securities Act of the Registration Statement, the Preliminary Prospectus, any Issuer Free Writing Prospectus, any Time of Sale Information and the Prospectus (including all exhibits, amendments and supplements thereto) and the distribution thereof; (iii) the fees and expenses of the Company’s counsel and independent accountants; (iv) the fees and expenses incurred in connection with the registration or qualification and determination of eligibility for investment of the Securities under the laws of such jurisdictions as the Representatives may designate and the preparation, printing and distribution of a Blue Sky Memorandum (including the related fees and expenses of counsel for the Underwriters); (v) any fees charged by rating agencies for rating the Securities; (vi) the fees and expenses of the Trustee and any paying agent (including related fees and expenses of any counsel to such parties); (vii) all expenses and application fees incurred in connection with any filing with, and clearance of any offering by, FINRA; and (viii) all expenses incurred by the Company in connection with any “road show” presentation to potential investors.

Section 11. Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and any controlling persons referred to herein, and the affiliates of each Underwriter referred to in Section 7 hereof. Nothing in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. No purchaser of Securities from any Underwriter shall be deemed to be a successor merely by reason of such purchase.

Section 12. Survival. The respective indemnities, rights of contribution, representations, warranties and agreements of the Company and the Underwriters contained in this Agreement or made by or on behalf of the Company or the Underwriters pursuant to this Agreement or any certificate delivered pursuant hereto shall remain in full force and effect, regardless of any investigation made by or on behalf of the Company, the Underwriters or any controlling persons of the Company or Underwriter and shall survive the delivery of and payment for the Securities. The provisions of Sections 7 and 10 hereof shall survive any termination of this Agreement.

Section 13. Certain Defined Terms. For purposes of this Agreement, (a) except where otherwise expressly provided, the term “affiliate” has the meaning set forth in Rule 405 under the Securities Act; (b) the term “business day” means any day that is not a Saturday or Sunday, and that is not a day on which banking institutions in the City of New York are authorized or obligated by law, regulation or executive order to close; and (c) the term “subsidiary” has the meaning set forth in Rule 405 under the Securities Act.

Exhibit A-16

Section 14. Miscellaneous. (a) Authority of the Representatives. Any action by the Underwriters hereunder may be taken by the Representatives on behalf of the Underwriters, and any such action taken by the Representatives shall be binding upon the Underwriters.

Section 15. Recognition of the U.S. Special Resolution Regimes. (a) In the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

Notwithstanding the foregoing, this Seventeenth Supplemental Indenture shall apply only to the Notes.

ARTICLE 2

Definitions

Section 2.1 Definitions and Other Provisions of General Application. For all purposes of this Seventeenth Supplemental Indenture unless otherwise specified herein:

“Issue Date” means September 6, 2024.

“Applicable Procedures” means, with respect to any transfer, transaction or other action involving a Global Security or any beneficial interest therein, the rules and procedures of the Depositary for such Security, in each case to the extent applicable to such transfer, transaction or other action as in effect from time to time.

2

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

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

(1) the sum of: (a) an alternate rate of interest that has been selected or recommended by the Relevant Governmental Body as the replacement for the then-current Benchmark and (b) the Benchmark Replacement Adjustment;

(2) the sum of: (a) the ISDA Fallback Rate and (b) the Benchmark Replacement Adjustment; or

(3) the sum of: (a) the alternate rate of interest that has been selected by the Company or the Company’s designee as the replacement for the then-current Benchmark giving due consideration to any industry-accepted rate of interest as a replacement for the then-current Benchmark for U.S. dollar denominated floating rate notes at such time and (b) the Benchmark Replacement Adjustment.

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

(1) the spread adjustment (which may be a positive or negative value or zero), or method for calculating or determining such spread adjustment, that has been selected or recommended by the Relevant Governmental Body for the applicable Unadjusted Benchmark Replacement;

(2) if the applicable Unadjusted Benchmark Replacement is equivalent to the ISDA Fallback Rate, the ISDA Fallback Adjustment; or

(3) the spread adjustment (which may be a positive or negative value or zero) that has been selected by the Company or the Company’s designee giving due consideration to any industry-accepted spread adjustment, or method for calculating or determining such spread adjustment, for the replacement of the then-current Benchmark with the applicable Unadjusted Benchmark Replacement for U.S. dollar denominated floating rate notes at such time.

3

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

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

(1) in the case of clause (1) or (2) of the definition of “Benchmark Transition Event,” the later of (a) the date of the public statement or publication of information referenced therein and (b) the date on which the administrator of the Benchmark permanently or indefinitely ceases to provide the Benchmark (or such component); or

(2) in the case of clause (3) of the definition of “Benchmark Transition Event,” the date of the public statement or publication of information referenced therein.

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

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

(1) a public statement or publication of information by or on behalf of the administrator of the Benchmark (or such component) announcing that such administrator has ceased or will cease to provide the Benchmark (or such component), permanently or indefinitely; provided that, at the time of such statement or publication, there is no successor administrator that will continue to provide the Benchmark (or such component);

(2) a public statement or publication of information by the regulatory supervisor for the administrator of the Benchmark (or such component), the central bank for the currency of the Benchmark (or such component), an insolvency official with jurisdiction over the administrator for the Benchmark (or such component), a

4

resolution authority with jurisdiction over the administrator for the Benchmark (or such component) or a court or an entity with similar insolvency or resolution authority over the administrator for the Benchmark (or such component), which states that the administrator of the Benchmark (or such component) has ceased or will cease to provide the Benchmark (or such component) permanently or indefinitely; provided that, at the time of such statement or publication, there is no successor administrator that will continue to provide the Benchmark (or such component); or

(3) a public statement or publication of information by the regulatory supervisor for the administrator of the Benchmark announcing that the Benchmark is no longer representative.

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

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

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

FIFTH THIRD BANCORP

4.895% Fixed Rate/Floating Rate Senior Notes due 2030

THIS SECURITY IS NOT A DEPOSIT AND IS NOT INSURED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION, THE DEPOSIT INSURANCE FUND OR ANY OTHER GOVERNMENTAL AGENCY, NOR IS IT AN OBLIGATION OF, OR GUARANTEED BY, A BANK.

Fifth Third Bancorp, a corporation duly organized and existing under the laws of Ohio (herein called the “Company”, which term includes any successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay to CEDE & CO., or registered assigns, the principal sum of Five Hundred Million United States Dollars ($500,000,000) on September 6, 2030 (the “Maturity Date”), and to pay interest thereon (a) from and including September 6, 2024 (the “Original Issue Date”) to, but excluding September 6, 2029 (the “Fixed Rate Period”) at the rate of 4.895% per annum, such interest to be payable semi-annually in arrears during the Fixed Rate Period on March 6 and September 6 of each year, with payment commencing on March 6, 2025 and ending on September 6, 2029 (each, a “Fixed Rate Interest Payment Date”), and (b) from, and including September 6, 2029 to, but excluding the Maturity Date (the “Floating Rate Period”), at a floating rate per annum equal to the Compounded SOFR (determined with respect to each quarterly interest period using the SOFR Index) plus 1.486%, such interest to be payable quarterly in arrears during the Floating Rate Period on December 6, 2029, March 6, 2030, June 6, 2030 and at the Maturity Date (each, a “Floating Rate Interest Payment Date” and, together with the Fixed Rate Interest Payment Dates, each, an “Interest Payment Date”), until the principal hereof is paid or made available for payment, and (in each case, to the extent that the payment of such interest specified in (a) or (b) shall be legally enforceable), at the same rate per annum on any overdue principal and premium and on any overdue installment of interest. Interest shall accrue from, and including, September 6, 2024 to, but excluding, the first Interest Payment Date and then from, and including, the immediately preceding Interest Payment Date to which interest has been paid or duly provided for to, but excluding, the next Interest Payment Date or the Maturity Date, as the case may be. Interest payable during the Fixed Rate Period will be computed on the basis of a 360-day year consisting of twelve 30-day months. Interest payable during the Floating Rate Period will be computed on the basis of the actual number of days in each interest period (or any other relevant period) and a 360-day year. The amount of accrued interest payable on this Security for each interest period during the Floating Rate Period will be computed by multiplying (x) the outstanding principal amount of this Security by (y) the product of (i) the interest rate for the relevant interest period multiplied by (ii) the quotient of the actual number of days in the applicable Observation Period relating to such interest period (or any other relevant period) divided by 360. The interest rate on this Security during the Floating Rate Period will in no event be lower than zero. The interest so

payable, and punctually paid or duly provided for, on any Interest Payment Date, subject to certain exceptions, will, as provided in the Indenture, be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on the record date for such interest period, which shall be 15 days, whether or not a Business Day, immediately preceding such Interest Payment Date. Any such interest not so punctually paid or duly provided for will forthwith cease to be payable to the Holder on such record date and may either be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on a record date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of Securities of this series not less than 10 days prior to such record date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities may be listed, and upon such notice as may be required by such exchange, all as more fully provided in said Indenture.

If a Fixed Rate Interest Payment Date or the Maturity Date falls on a day that is not a Business Day, the Company will postpone the interest payment or the payment of principal and interest at maturity to the next succeeding Business Day, but the payments made on such dates will be treated as being made on the date that the payment was first due and the Holder will not be entitled to any further interest or other payments with respect to such postponements. If a Floating Rate Interest Payment Date falls on a day that is not a Business Day, the Company will postpone the interest payment to the next succeeding Business Day, except that, if the next succeeding Business Day falls in the next calendar month, then such interest payment will be advanced to the immediately preceding day that is a Business Day and, in each case, the related interest periods also will be adjusted for such non-Business Days. Payment of the principal of (and premium, if any) and interest on this Security will be made at the office or agency of the Company maintained for that purpose in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided, however, that at the option of the Company payment of interest may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register. The Company shall make, or cause the Paying Agent to make, all payments of principal and interest on Global Securities in immediately available funds to the Depositary or its nominee, in accordance with Applicable Procedures.

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

Unless the certificate of authentication hereon has been executed by the Trustee referred to on the reverse hereof by manual signature, this Security shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

IN WITNESS WHEREOF, the Company has caused this instrument to be duly executed.

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

(1) the sum of: (a) an alternate rate of interest that has been selected or recommended by the Relevant Governmental Body as the replacement for the then-current Benchmark and (b) the Benchmark Replacement Adjustment;

(2) the sum of: (a) the ISDA Fallback Rate and (b) the Benchmark Replacement Adjustment; or

(3) the sum of: (a) the alternate rate of interest that has been selected by the Company or the Company’s designee as the replacement for the then-current Benchmark giving due consideration to any industry-accepted rate of interest as a replacement for the then-current Benchmark for U.S. dollar denominated floating rate notes at such time and (b) the Benchmark Replacement Adjustment.

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

(1) a public statement or publication of information by or on behalf of the administrator of the Benchmark (or such component) announcing that such administrator has ceased or will cease to provide the Benchmark (or such component), permanently or indefinitely; provided that, at the time of such statement or publication, there is no successor administrator that will continue to provide the Benchmark (or such component);

(3) a public statement or publication of information by the regulatory supervisor for the administrator of the Benchmark announcing that the Benchmark is no longer representative.

Fifth Third Bancorp, a corporation duly organized and existing under the laws of Ohio (herein called the “Company”, which term includes any successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay to CEDE & CO., or registered assigns, the principal sum of Five Hundred Million United States Dollars ($500,000,000) on September 6, 2030 (the “Maturity Date”), and to pay interest thereon (a) from and including September 6, 2024 (the “Original Issue Date”) to, but excluding September 6, 2029 (the “Fixed Rate Period”) at the rate of 4.895% per annum, such interest to be payable semi-annually in arrears during the Fixed Rate Period on March 6 and September 6 of each year, with payment commencing on March 6, 2025 and ending on September 6, 2029 (each, a “Fixed Rate Interest Payment Date”), and (b) from, and including September 6, 2029 to, but excluding the Maturity Date (the “Floating Rate Period”), at a floating rate per annum equal to the Compounded SOFR (determined with respect to each quarterly interest period using the SOFR Index) plus 1.486%, such interest to be payable quarterly in arrears during the Floating Rate Period on December 6, 2029, March 6, 2030, June 6, 2030 and at the Maturity Date (each, a “Floating Rate Interest Payment Date” and, together with the Fixed Rate Interest Payment Dates, each, an “Interest Payment Date”), until the principal hereof is paid or made available for payment, and (in each case, to the extent that the payment of such interest specified in (a) or (b) shall be legally enforceable), at the same rate per annum on any overdue principal and premium and on any overdue installment of interest.

If a Fixed Rate Interest Payment Date or the Maturity Date falls on a day that is not a Business Day, the Company will postpone the interest payment or the payment of principal and interest at maturity to the next succeeding Business Day, but the payments made on such dates will be treated as being made on the date that the payment was first due and the Holder will not be entitled to any further interest or other payments with respect to such postponements. If a Floating Rate Interest Payment Date falls on a day that is not a Business Day, the Company will postpone the interest payment to the next succeeding Business Day, except that, if the next succeeding Business Day falls in the next calendar month, then such interest payment will be advanced to the immediately preceding day that is a Business Day and, in each case, the related interest periods also will be adjusted for such non-Business Days.

Unless the certificate of authentication hereon has been executed by the Trustee referred to on the reverse hereof by manual signature, this Security shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

Ladies and Gentlemen:

We have acted as counsel to Fifth Third Bancorp, an Ohio corporation (the “Corporation”), in connection with the Registration Statement on Form S-3 (the “Registration Statement”) filed by the Corporation with the Securities and Exchange Commission under the Securities Act of 1933, as amended (the “Act”), and prospectus filed in connection with the registration of the Corporation’s 4.895% Fixed Rate/Floating Rate Senior Notes due 2030 in the aggregate principal amount of $750,000,000 (the “Senior Debt Securities”) being issued by the Corporation pursuant to the Indenture dated as of April 30, 2008, as amended by Article 4 of a Twelfth Supplemental Indenture dated as of April 25, 2022, between the Corporation and Wilmington Trust Company, as trustee, as such Indenture has been supplemented by a Seventeenth Supplemental Indenture dated as of September 6, 2024 (together, the “Senior Debt Indenture”).

As counsel for the Corporation, we have examined such corporate records, certificates, documents and matters of law as we have deemed necessary or appropriate for the purposes of this opinion. In all such examinations, we have assumed the genuineness of signatures on original documents and the conformity to such original documents of all copies submitted to us as certified, conformed or photographic copies, and, as to statements of the officers of the Corporation and certificates of public officials, we have assumed the same to have been properly given and accurate.

Based upon such examination and the assumptions set forth herein, we are of the opinion that the Senior Debt Securities are valid and legally binding obligations of the Corporation, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles.

The foregoing opinion is limited to the federal laws of the United States, the laws of the State of Ohio and the laws of the State governing the Senior Debt Securities, and we are expressing no opinion as to the effect of the laws of any other jurisdiction. We express no opinion as to whether, or the extent to which, the laws of any particular jurisdiction apply to the subject matter of the agreements and documents referred to herein, including without limitation the enforceability of the governing law provisions contained in such agreements and documents.
