As Representatives of the several

Underwriters named in Schedule I hereto

Dear Ladies and Gentlemen:

Capital One Financial Corporation, a Delaware corporation (the “Company”), proposes to issue and sell to the several underwriters named in Schedule I hereto (the “Underwriters”), for whom you are acting as representatives (the “Representatives”) $1,350,000,000 aggregate principal amount of 4.985% Fixed-to-Floating Rate Senior Notes Due 2026 (the “2026 Fixed-to-Floating Rate Notes”) and $900,000,000 aggregate principal amount of 5.247% Fixed-to-Floating Rate Senior Notes Due 2030 (the “2030 Fixed-to-Floating Rate Notes,” together with the 2026 Fixed-to-Floating Rate Notes, the “Securities”). The Securities are to be issued pursuant to the provisions of a Senior Indenture dated as of November 1, 1996 (the “Base Indenture”)

between the Company and The Bank of New York Mellon Trust Company, N.A., formerly known as The Bank of New York Trust Company, N.A. (as successor to Harris Trust and Savings Bank), as Trustee (the “Trustee”), as supplemented by a First Supplemental Indenture dated as of November 2, 2021 (the “Supplemental Indenture” and together with the Base Indenture, the “Senior Indenture”) between the Company and the Trustee.

1. Registration Statement and Prospectus. The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3 (File No. 333-254191) under the Securities Act of 1933, as amended (the “Securities Act”) in respect of its senior debt securities, subordinated debt securities, shares of its preferred stock, depositary shares, shares of its common stock, purchase contracts, warrants and units (as amended through the date of this Agreement, being herein referred to as the “Registration Statement”). Such Registration Statement has become effective. The Registration Statement contains a base prospectus in the form in which it has most recently been filed with the Commission on or prior to the date of this Agreement (the “Base Prospectus”), to be used in connection with the public offering and sale of the Securities. Any preliminary prospectus supplement to the Base Prospectus that describes the Securities and the offering thereof and is used prior to filing of the Prospectus is called, together with the Base Prospectus, a “preliminary prospectus.” The term “Prospectus” shall mean the final prospectus supplement relating to the Securities, together with the Base Prospectus, that is first filed pursuant to Rule 424(b) under the Securities Act after the date and time that this Agreement is executed and delivered by the parties hereto but shall not include any free writing prospectus (as such term is used in Rule 405 under the Securities Act). Any Prospectus or preliminary prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act; any reference to any amendment or supplement to any preliminary prospectus or the Prospectus shall be deemed to refer to and include any documents filed after the date of such preliminary prospectus or Prospectus, as the case may be, under the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder (collectively, the “Exchange Act”), and incorporated by reference in such preliminary prospectus or Prospectus, as the case may be. The Company also has prepared and filed (or will file) with the Commission the Issuer Free Writing Prospectuses (as defined below) set forth on Schedule II hereto. All references in this Agreement to the Registration Statement, a preliminary prospectus, the Prospectus, or any amendments or supplements to any of the foregoing, shall include any copy thereof filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval System (“EDGAR”).

2. Agreements to Sell and Purchase. On the basis of the representations and warranties contained in this Agreement, and subject to its terms and conditions, the Company agrees to issue and sell to the Underwriters, and each Underwriter agrees, severally and not jointly, to purchase from the Company the principal amount of Securities set forth opposite the name of such Underwriter in Schedule I hereto, at a price (the “Purchase Price”) equal to (i) with respect to the 2026 Fixed-to-Floating Rate Notes, 99.750% of the principal amount thereof, plus accrued interest thereon, if any, from July 27, 2022 to the date of payment and delivery and (ii) with respect to the 2030 Fixed-to-Floating Rate Notes, 99.600% of the principal amount thereof, plus accrued interest thereon, if any, from July 27, 2022 to the date of payment and delivery.

3. Terms of Public Offering. The Company is advised by the Representatives that the Underwriters propose (i) to make a public offering of their respective portions of the Securities as soon after the execution hereof as practicable and (ii) initially to offer the Securities upon the terms set forth in the Prospectus.

4. Delivery and Payment. The Company will deliver, or cause to be delivered, the Securities to the Representatives for the account of each Underwriter against payment by or on behalf of such Underwriter of the Purchase Price by wire transfer of Federal (same-day) funds to the account specified by the Company to the Representatives at least twenty-four hours in advance, by causing the Trustee as registrar, to register the Securities in the name of Cede & Co., or such other nominee as The Depository Trust Company (“DTC”) may designate, and shall cause DTC to credit the Securities to the account of Morgan Stanley & Co. LLC at DTC. The time and date of such delivery and payment shall be 10:00 a.m., New York City time on the second business day following the date of the Prospectus (the “Closing Date”), or such other time and date as the Representatives and the Company may agree upon in writing.

5. Agreements of the Company. The Company agrees with the Underwriters:

(a) To file the Prospectus with the Commission pursuant to Rule 424(b)(5) not later than the second business day following the execution and delivery of this Agreement.

(b) During the period beginning at the Time of Sale (as defined below) and ending on the later of the Closing Date or such date as in the opinion of counsel for the Underwriters, the Prospectus is no longer required by law to be delivered in connection with sales by an Underwriter or dealer, including in circumstances where such requirement may be satisfied pursuant to Rule 172 (the “Prospectus Delivery Period”), prior to amending or supplementing the Registration Statement, the Disclosure Package (as defined below) or the Prospectus (including any amendment or supplement through incorporation by reference of any report filed under the Exchange Act), the Company shall furnish to the Representatives for review a copy of each such proposed amendment or supplement.

(c) If, during the Prospectus Delivery Period, any event or development shall occur or condition exist as a result of which the Disclosure Package or the Prospectus as then amended and supplemented would include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if in the judgment of the Company it shall be necessary to amend or supplement the Disclosure Package or the Prospectus, or to file under the Exchange Act any document incorporated by reference in the Disclosure Package or the Prospectus, in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it is otherwise necessary to amend or supplement the Registration Statement, the Disclosure Package or the Prospectus, or to file under the Exchange Act any document incorporated by reference in the Disclosure Package or the Prospectus, or to file a new registration statement containing the Prospectus, in order to comply with law, including in connection with the delivery of the Prospectus, the Company agrees to (i) notify the Representatives of any such event or condition and (ii) promptly prepare (subject to paragraph (b) above), file with the Commission (and use its best efforts to have any amendment to the Registration Statement or any new registration statement be declared effective) and furnish at its

3

own expense to the Underwriters and to dealers, amendments or supplements to the Registration Statement, the Disclosure Package or the Prospectus, or any new registration statement, necessary in order to make the statements in the Disclosure Package or the Prospectus as so amended or supplemented, in the light of the circumstances then prevailing or under which they were made, not misleading or so that the Registration Statement, the Disclosure Package or the Prospectus, as amended or supplemented, will comply with law.

(d) The Company will prepare a final term sheet for the Securities containing only a description of the Securities, in a form approved by the Representatives, and will file such term sheet pursuant to Rule 433(d) under the Securities Act within the time required by such rule (the “Final Term Sheet”). Any such Final Term Sheet is an Issuer Free Writing Prospectus for purposes of this Agreement.

(e) The Company represents that (other than the Final Term Sheet) it has not made, and agrees that, unless it obtains the prior written consent of the Representatives, it will not make, any offer relating to the Securities that would constitute an issuer free writing prospectus as defined in Rule 433 of the Securities Act (each, an “Issuer Free Writing Prospectus”) or that would otherwise constitute a “free writing prospectus” as defined in Rule 405 of the Securities Act required to be filed by the Company with the Commission or retained by the Company under Rule 433 of the Securities Act; provided that the prior written consent of the Representatives shall be deemed to have been given in respect of any Free Writing Prospectus included in Schedule II hereto. Any such free writing prospectus consented to by the Representatives is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company agrees that (i) it has treated and will treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus, and (ii) has complied or will comply, as the case may be, with the requirements of Rules 164 and 433 of the Securities Act applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with the Commission, legending and record keeping. The Company consents to the use by any Underwriter of (i) a free writing prospectus that contains no “issuer information” (as defined in Rule 433(h)(2) under the Securities Act) that was not included (including through incorporation by reference) in the Prospectus or a previously filed Issuer Free Writing Prospectus, (ii) any Issuer Free Writing Prospectus listed on Schedule II hereto, or (iii) (x) information describing the preliminary terms of the Securities or their offering or (y) information that describes the final terms of the Securities or their offering and that is included in the Final Term Sheet.

7. Representations and Warranties of the Underwriters. Each Underwriter hereby represents and agrees that it has not and will not make any offer relating to the Securities that would constitute a “free writing prospectus” as defined in Rule 405 under the Securities Act without the prior consent of the Company or as permitted in Section 5(e) above and that Schedule II hereto is a complete list of any free writing prospectuses for which the Underwriters have received such consent.

8. Indemnification. (a) The Company agrees to indemnify and hold harmless each Underwriter, each of its directors, officers and agents, and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and each affiliate of any Underwriter within the meaning of Rule 405 under the Securities Act, from and against any and all losses, claims, damages, liabilities and judgments arising out of or based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Prospectus, the Disclosure Package or any Issuer Free Writing Prospectus (each as amended or supplemented if the Company shall have furnished any amendments or supplements thereto) or any preliminary prospectus, or arising out of or based upon any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages, liabilities or judgments are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to any Underwriter furnished in writing to the Company by or on behalf of such Underwriter through the Representatives expressly for use therein, it being understood and agreed that the only such information furnished by or on behalf of any Underwriter consists of the information described as such in Section 8(c).

(b) In case any action shall be brought against any indemnified party based upon any preliminary prospectus, the Registration Statement, the Prospectus or the Disclosure Package or any amendment or supplement thereto and with respect to which indemnity may be sought against the Company, such indemnified party shall promptly notify the Company in writing and the Company shall have the right to participate therein and, to the extent that it may elect by written notice delivered to such indemnified party promptly after receiving the aforesaid notice from such indemnified party, assume the defense thereof, including the employment of counsel reasonably satisfactory to such indemnified party and payment of all fees and expenses. Any indemnified party shall have the right to employ separate counsel in any such action and

13

participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the employment of such counsel shall have been specifically authorized in writing by the Company, (ii) the Company shall have failed to assume the defense and employ counsel or (iii) the named parties to any such action (including any impleaded parties) include both such indemnified party and the Company and such indemnified party shall have been advised by such counsel that there may be one or more legal defenses available to it which are different from or additional to those available to the Company (in which case the Company shall not have the right to assume the defense of such action on behalf of such indemnified party, it being understood, however, that the Company shall not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) for all such indemnified parties, which firm shall be designated in writing by the Representatives, and that all such reasonable fees and expenses shall be reimbursed as they are incurred). The Company shall not be liable for any settlement of any such action effected without its written consent but if settled with the written consent of the Company, the Company agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes (i) an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and (ii) does not include any statement as to, or an admission of, fault, culpability or failure to act by or on behalf of any indemnified party.

(c) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, each of its directors and each of its officers who signs the Registration Statement and each person controlling the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, to the same extent as the foregoing indemnity from the Company to each Underwriter but only to the extent of losses, claims, damages, liabilities and judgments arising out of or based upon information relating to such Underwriter furnished in writing by or on behalf of such Underwriter expressly for use in the Registration Statement, the Base Prospectus, the Disclosure Package or the Prospectus. The Representatives confirm that the Underwriters’ names on the cover page of the preliminary prospectus supplement and the Prospectus and the Underwriters’ names in the table in the first paragraph and the statements set forth in the third paragraph, the third sentence of the sixth paragraph, the seventh paragraph, the eighth paragraph, the ninth paragraph, the first sentence of the tenth paragraph, and the eleventh paragraph under the heading “Underwriting (Conflict of Interest)” in the preliminary prospectus supplement and the Prospectus were furnished in writing to the Company by or on behalf of the Underwriters expressly for use therein. In case any action shall be brought against the Company, any of its directors, any such officer or any person controlling the Company based on the Registration Statement, the Base Prospectus, any preliminary prospectus or the Prospectus and in respect of which indemnity may be sought against any Underwriter, the Underwriter shall have the rights and duties given to the Company, and the Company, its directors, any such officers and any person controlling the Company shall have the rights and duties given to the Underwriter, by Section 8(b) hereof.

14

(d) If the indemnification provided for in paragraphs (a), (b) and (c) of this Section 8 is unavailable to an indemnified party in respect of any losses, claims, damages, liabilities or judgments referred to therein, then each indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities and judgments (i) in such proportion as is appropriate to reflect the relative benefits received by the indemnifying party on the one hand and the indemnified party on the other hand from the offering of the Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the indemnifying party on the one hand and the indemnified party on the other hand in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or judgments, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Underwriters shall be deemed to be in the same respective proportion as the total net proceeds from the offering (before deducting expenses) received by the Company, and the total underwriting discounts and commissions received by the Underwriters, bear to the total price to the public of the Securities, in each case as set forth in the table on the cover page of the Prospectus. The relative fault of the Company and the Underwriters shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the Company or the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8(d) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities or judgments referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ respective obligations to contribute pursuant to this Section 8(d) are several in proportion to the respective amount of Securities purchased by each of the Underwriters hereunder and not joint.

For purposes of this Section 8, each person, if any, who controls an Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and each Underwriter’s affiliates, officers, directors and agents shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company within the

15

meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Company.

9. Conditions of Underwriters’ Obligations. The several obligations of the Underwriters to purchase the Securities under this Agreement are subject to the satisfaction of each of the following conditions:

(a) All the representations and warranties of the Company contained in this Agreement shall be true and correct on the Closing Date with the same force and effect as if made on and as of the Closing Date.

(c) The Final Term Sheet and any other material required to be filed by the Company pursuant to Rule 433(d) under the Securities Act, shall have been filed with the Commission within the applicable time periods prescribed for such filings under Rule 433.

(d) Subsequent to the execution and delivery of this Agreement and prior to the Closing Date, there shall not have been any downgrading, nor shall any notice have been given of any intended or potential downgrading or of any review for a possible change that does not indicate the direction of the possible change, in the rating accorded any of the Company’s securities by any “nationally recognized statistical rating organization,” as such term is defined under Section 3(a)(62) of the Exchange Act.

(e) (i) Since the date of the latest balance sheet included in the Registration Statement and the Prospectus, there shall not have been any material adverse change, or any development involving a prospective material adverse change, in the condition, financial or otherwise, or in the earnings, affairs or business prospects, whether or not arising in the ordinary course of business, of the Company and its subsidiaries taken as a whole, except as set forth or contemplated in the Registration Statement and the Prospectus, (ii) since the date of the latest balance sheet included in the Registration Statement and the Prospectus there shall not have been any material adverse change, or any development involving a prospective material adverse change, in the capital stock or in the long-term debt of the Company from that set forth or contemplated in the Registration Statement and Prospectus, (iii) the Company and its subsidiaries shall have no liability or obligation, direct or contingent, which is material to the Company and its subsidiaries, taken as a whole, other than those reflected in the Registration Statement and the Prospectus and (iv) on the Closing Date, the Underwriters shall have received a certificate dated the Closing Date, signed by the Treasurer of the Company, confirming the matters set forth in paragraphs (a), (b), (c), (d) and (e) (i) – (iii) of this Section 9.

(h) The Underwriters shall have received on the Closing Date, an opinion, dated the Closing Date, of Mayer Brown LLP, counsel for the Underwriters, covering such matters as the Representatives may request.

(i) The Underwriters shall have received letters on and as of the date hereof and on and as of the Closing Date, in form and substance satisfactory to the Representatives, from Ernst & Young LLP, independent public accountants, with respect to the financial statements and certain financial information of the Company contained in the Registration Statement, any preliminary prospectus and the Prospectus.

(j) The Company shall not have failed at or prior to the Closing Date to perform or comply with any of the agreements herein contained and required to be performed or complied with by the Company at or prior to the Closing Date.

10. Effective Date of Agreement and Termination. This Agreement shall become effective upon the execution of this Agreement.

This Agreement may be terminated at any time prior to the Closing Date by the Representatives by written notice to the Company if any of the following has occurred: (i) since the respective dates as of which information is given in the Registration Statement and the Prospectus and since the Time of Sale, any material adverse change or development involving a prospective material adverse change (including, without limitation, the enactment, publication, decree or other promulgation of any federal or state statute, regulation, rule or order of any court or other governmental authority) in the condition, financial or otherwise, of the Company and its subsidiaries taken as a whole or the earnings, affairs, or business prospects of the Company and its subsidiaries taken as a whole, whether or not arising in the ordinary course of business, which would, in the judgment of the Representatives, make it impracticable to market the Securities on the terms and in the manner contemplated in the Prospectus, (ii) any outbreak or escalation of hostilities or other national or international calamity or crisis (including, without limitation, an act of terrorism) or change in economic conditions or in the financial markets of the United States or elsewhere that, in the judgment of the Representatives, is material and adverse and would, in the judgment of the Representatives, make it impracticable to market the Securities on the terms and in the manner contemplated in the Prospectus, (iii) the suspension or material limitation of trading in securities generally, or in the securities of the Company listed, on the New York Stock Exchange, the NYSE American or The Nasdaq Stock Market, or a limitation on prices on any such exchange, (iv) a material disruption in securities settlement that makes it impracticable to deliver the Securities in the manner contemplated by the Prospectus, or (v) the taking of any action by any federal, state or local government or agency in respect of its monetary or fiscal affairs which in the opinion of the Representatives has a material adverse effect on the financial markets in the United States.

If on the Closing Date any one or more of the Underwriters shall fail or refuse to purchase and pay for any of the Securities which it or they have agreed to purchase hereunder on

17

such date and the aggregate principal amount of the Securities which such defaulting Underwriter or Underwriters, as the case may be, agreed but failed or refused to purchase is not more than one-tenth of the total principal amount of Securities to be purchased on such date by all Underwriters, each non-defaulting Underwriter shall be obligated severally, in the proportion which the principal amount of Securities set forth opposite its name in Schedule I bears to the total principal amount of Securities which all the non-defaulting Underwriters, as the case may be, have agreed to purchase, or in such other proportion as the Representatives may specify, to purchase the Securities which such defaulting Underwriter or Underwriters, as the case may be, agreed but failed or refused to purchase on such date; provided that in no event shall the principal amount of Securities which any Underwriter has agreed to purchase pursuant to Section 2 hereof be increased pursuant to this Section 10 by an amount in excess of one-ninth of such principal amount of Securities without the written consent of such Underwriter. If on the Closing Date any Underwriter or Underwriters shall fail or refuse to purchase Securities and the aggregate principal amount of Securities with respect to which such default occurs is more than one-tenth of the aggregate principal amount of Securities to be purchased on such date by all Underwriters and arrangements satisfactory to the Representatives and the Company for purchase of such Securities are not made within 48 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter and the Company. In any such case which does not result in termination of this Agreement, either the Representatives or the Company shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement and the Prospectus or any other documents or arrangements may be effected. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of any such Underwriter under this Agreement.

11. No Agency or Fiduciary Duty. The Company acknowledges and agrees that: (i) the purchase and sale of the Securities pursuant to this Agreement, including the determination of the public offering price of the Securities and any related discounts and commissions, is an arm’s length commercial transaction between the Company, on the one hand, and the several Underwriters, on the other hand, and the Company is capable of evaluating and understanding and understands and accepts the terms, risks and conditions of the transactions contemplated by this Agreement; (ii) in connection with each transaction contemplated hereby, each Underwriter is and has been acting solely as a principal and is not the agent or fiduciary of the Company or its affiliates, stockholders, creditors or employees or any other party; (iii) no Underwriter has assumed an advisory, agency or fiduciary responsibility in favor of the Company with respect to any of the transactions contemplated hereby (irrespective of whether such Underwriter has advised or is currently advising the Company on other matters) and no Underwriter has any obligation to the Company with respect to the offering contemplated hereby except the obligations expressly set forth in this Agreement; (iv) the several Underwriters and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company and the several Underwriters have no obligation to disclose any of such interests by virtue of any advisory, agency or fiduciary relationship; and (v) the Underwriters have not provided any legal accounting, regulatory or tax advice with respect to the offering contemplated hereby and the Company has consulted its own legal, accounting, regulatory and tax advisors to the extent it deemed appropriate. The Company acknowledges that none of the activities of the Underwriters in connection with the offering of the Securities

18

constitutes a recommendation, investment advice, or solicitation of any action by the Underwriters with respect to the Company.

This Agreement supersedes all prior agreements and understandings (whether written or oral) among the Company and the several Underwriters, or any of them, with respect to the subject matter hereof. The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against the several Underwriters with respect to any breach or alleged breach of agency or fiduciary duty.

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

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

This Security is one of a duly authorized issue of debt securities of the Company, of the series hereinafter specified, all issued or to be issued under a Senior Indenture, dated as of November 1, 1996 (the “Base Indenture”), as supplemented by a First Supplemental Indenture, dated as of November 2, 2021 (the “Supplemental Indenture” and, together with the Base Indenture, the “Senior Indenture”) and each, duly executed and delivered by the Company to The Bank of New York Mellon Trust Company, N.A., formerly known as The Bank of New York Trust Company, N.A. (as successor to Harris Trust and Savings Bank), as trustee (hereinafter, the “Trustee”). Reference to the Senior Indenture and the Officer’s Certificate thereunder establishing the terms of this Security is hereby made for a description of the respective rights and duties thereunder of the Trustee, the Company and the Holders of the Securities. This Security is one of a series designated as the “4.985% Fixed-to-Floating Rate Senior Notes Due 2026” of the Company (hereinafter called the “Notes”), issued under the Senior Indenture. Each Holder by accepting a Note, agrees to be bound by all terms and provisions of the Senior Indenture, as amended from time to time, applicable to the Notes.

Neither the Senior Indenture nor the Notes limit or otherwise restrict the amount of indebtedness which may be incurred or other securities which may be issued by the Company. The Notes issued under the Senior Indenture are direct, unsecured obligations of the Company and will mature on July 24, 2026. The Notes rank on parity with all other unsecured, unsubordinated indebtedness of the Company.

The Company promises to pay interest on the principal amount of this Security (i) from and including July 27, 2022 to, but excluding, July 24, 2025 (the “Fixed Rate Period”), at a fixed rate of 4.985% per annum, semi-annually in arrears, on January 24 and July 24 of each year (each such date, a “Fixed Rate Interest Payment Date”), commencing on January 24, 2023 and ending on July 24, 2025, and (ii) from and including July 24, 2025 to but excluding the Stated Maturity (the “Floating Rate Period”), at an annual rate equal to the Base Rate (as defined and computed below) plus 2.160% (the “Spread”), quarterly in arrears, on the second Business Day (as defined below) following each Floating Rate Interest Period End-Date (as defined below) (each such Business Day, a “Floating Rate Interest Payment Date” and together with any Fixed Rate Period Payment Date, an “Interest Payment Date), until the principal hereof is paid or made available for payment.

Notwithstanding the above, the Floating Rate Interest Payment Date with respect to the final Floating Rate Interest Payment Period (as defined below) shall be the Stated Maturity.

The Company will pay interest to the holder in whose name this Security is registered at the close of business on the fifteenth calendar day (whether or not a Business Day (as defined below)), immediately preceding the related Fixed Rate Interest Payment Date or Floating Rate Interest Payment Period End-Date (as defined below), as applicable (such date being referred to herein as the “Regular Record Date”), except that the Company will pay interest at the Stated

Maturity or, if the Notes are redeemed, the Redemption Date to the person or persons to whom principal is payable.

During the Fixed Rate Period, interest shall be paid on the basis of a 360-day year comprised of twelve 30-day months. If any date on which interest is payable is not a Business Day, the payment of the interest payable on that date shall be made on the next day that is a Business Day without any interest or other payment in respect of the delay, with the same force and effect as if made on the date such payment were due, and no interest shall accrue on the amount payable for the period from and after such Fixed Rate Interest Payment Date.

During the Floating Rate Period, interest shall be paid on the basis of a 360-day year and the actual number of days elapsed.

For purposes of this Note, and in calculating the interest to be paid during the Floating Rate Period:

During the Floating Rate Period, the index maturity (the “Index Maturity”) for the Notes shall be daily.

During the Floating Rate Period, the Base Rate shall be SOFR (compounded daily over a quarterly Floating Rate Interest Payment Period in accordance with the specific formula described below). As further described below, (x) in determining the Base Rate for a U.S. Government Securities Business Day, the Base Rate generally will be the rate in respect of such day that is provided on the following U.S. Government Securities Business Day and (y) in determining the Base Rate for any other day, such as a Saturday, Sunday or holiday, the Base Rate generally will be the rate in respect of the immediately preceding U.S. Government Securities Business Day that is provided on the following U.S. Government Securities Business Day.

The “Spread” is the number of basis points (one one-hundredth of a percentage point) specified above to be added to the accrued interest compounding factor for a Floating Rate Interest Payment Period. The amount of interest accrued and payable on the Notes for the Floating Rate Interest Payment Period will be equal to the outstanding principal amount of the Notes multiplied by the product of: (x) the sum of the accrued interest compounding factor plus the Spread for the relevant Floating Rate Interest Payment Period, multiplied by (y) the quotient obtained by dividing the actual number of calendar days in such Floating Rate Interest Payment Period by 360.

Notwithstanding the foregoing, in no event will the interest rate payable for any Floating Rate Interest Payment Period be less than zero percent.

On the Floating Rate Interest Payment Date, accrued interest will be paid for the most recently completed Floating Rate Interest Payment Period. During the Floating Rate Period, interest on the Notes will accrue from and including the most recent Floating Rate Interest Payment Period End-Date to which interest has been paid or duly provided for, or from and including July 24, 2025 in the case of the first Floating Rate Interest Payment Period. Interest will accrue to but excluding the next Floating Rate Interest Payment Period End-Date.

During the Floating Rate Period, the calculation agent shall notify the paying agent of each determination of the interest rate applicable to the notes promptly after the determination is made.

With respect to any Floating Rate Interest Payment Period, the accrued interest compounding factor means the rate of return of a daily compound interest investment computed in accordance with the following formula (with the resulting percentage rounded, if necessary, to

the nearest one hundred-thousandth of a percentage point, with 0.000005 being rounded upwards to 0.00001):

Where:

“d₀”, for any Floating Rate Interest Payment Period, is the number of U.S. Government Securities Business Days in the relevant Floating Rate Interest Payment Period.

“i” is a series of whole numbers from one to d₀, each representing the relevant U.S. Government Securities Business Days in chronological order from, and including, the first U.S. Government Securities Business Day in the relevant Floating Rate Interest Payment Period.

“SOFRi”, for any day “i” in the relevant Floating Rate Interest Payment Period, is a reference rate equal to SOFR in respect of that day.

“n_i” is the number of calendar days in the relevant Floating Rate Interest Payment Period on which the rate is SOFR_i.

“d” is the number of calendar days in the relevant Floating Rate Interest Payment Period.

For these calculations, the interest rate in effect on any U.S. Government Securities Business Day will be the applicable rate as reset on that date, except that the level of SOFR for each calendar day in the period from and including the Rate Cut-Off Date to but excluding the Maturity Date will be the level of SOFR in respect of such Rate Cut-Off Date. The interest rate applicable to any other day is the interest rate from the immediately preceding U.S. Government Securities Business Day.

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

In connection with the SOFR definition above, the following definitions apply:

“Benchmark” means SOFR with the Index Maturity specified above; provided that if a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to SOFR with the Index Maturity specified above or the then-current Benchmark, then “Benchmark” means the applicable Benchmark Replacement.

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

(3) the Spread adjustment (which may be a positive or negative value or zero) that has been selected by the Company or its 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.

“Benchmark Replacement Conforming Changes” means, with respect to any Benchmark Replacement, any technical, administrative or operational changes (including changes to the definition of “Floating Rate Interest Payment Periods,” timing and frequency of determining rates and making payments of interest and other administrative matters) that the Company or its designee decide may be appropriate to reflect the adoption of such Benchmark Replacement in a manner substantially consistent with market practice (or, if the Company or its designee decide that adoption of any portion of such market practice is not administratively feasible or if the Company or its designee determine that no market practice for use of the Benchmark Replacement exists, in such other manner as the Company or its designee determine is reasonably necessary).

“Benchmark Replacement Date” means the earliest to occur of the following events with respect to the then-current Benchmark:

(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:

If a Benchmark Transition Event and its related Benchmark Replacement Date have occurred, any determination, decision or election that may be made by the Company or its designee pursuant to this section, including any determination with respect to a tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action or any selection:

None of the Trustee, the paying agent or the calculation agent shall be under any obligation (i) to monitor, determine or verify the unavailability or cessation of SOFR or the SOFR index, or whether or when there has occurred, or to give notice to any other transaction party of the occurrence of, any Benchmark Transition Event or related Benchmark Replacement Date, (ii) to select, determine or designate any Benchmark Replacement, or other successor or replacement benchmark index, or whether any conditions to the designation of such a rate or index have been satisfied, or (iii) to select, determine or designate any Benchmark Replacement Adjustment, or other modifier to any replacement or successor index, or (iv) to determine whether or what Benchmark Replacement Conforming Changes are necessary or advisable, if any, in connection with any of the foregoing, including, but not limited to, adjustments as to any alternative spread thereon, the business day convention, interest determination dates or any other relevant methodology applicable to such substitute or successor benchmark. In connection with the foregoing, each of the Trustee, paying agent and calculation agent shall be entitled to conclusively rely on any determinations made by the Company or its designee without independent investigation, and none will have any liability for actions taken at the Company’s direction in connection therewith.

None of the Trustee, the paying agent or the calculation agent shall be liable for any inability, failure or delay on its part to perform any of its duties set forth in this note as a result of the unavailability of SOFR, the SOFR index or other applicable Benchmark Replacement, including as a result of any failure, inability, delay, error or inaccuracy on the part of any other transaction party in providing any direction, instruction, notice or information required or contemplated by the terms of this note and reasonably required for the performance of such duties. None of the Trustee, paying agent or calculation agent shall be responsible or liable for the Company’s actions or omissions or for those of its designee, or for any failure or delay in the performance by the Company or its designee, nor shall any of the Trustee, paying agent or calculation agent be under any obligation to oversee or monitor the Company’s performance or that of its designee.

The Company will pay interest in such coin or currency of the United States of America as at the time of payment shall be legal tender for the payment of public and private debts. The

Company will make payments in respect of Notes in global form (including principal and interest) to the Holder thereof or a nominee of the Holder, by wire transfer of immediately available funds as of the close of business on the date such payments are due.

The term “Business Day” means any day that is not a Saturday or Sunday and that is not a day on which banks in New York, New York, Chicago, Illinois or McLean, Virginia are generally authorized or required by law or executive order to be closed.

If the Company defaults in the payment of interest due on any Interest Payment Date after taking into account any applicable grace period, such defaulted interest shall be paid as set forth in the Senior Indenture.

The Notes are not entitled to any sinking fund.

The Notes are subject to defeasance pursuant to Section 402 of the Senior Indenture.

The Notes are not convertible into common stock of the Company.

The Company may redeem the Notes (the date of such redemption, the “Redemption Date”) at its option on July 24, 2025 (which is the date that is one year prior to the Stated Maturity), in whole but not in part, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest thereon to the Redemption Date upon not less than 10 nor more than 60 days’ prior notice given to the holders of the Notes to be redeemed.

If money sufficient to pay the redemption price of and accrued interest on the Notes to be redeemed on the Redemption Date is deposited with the Trustee 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 such Notes called for redemption and such Notes will cease to be outstanding. If the Redemption Date is not a business day, the Company will pay the redemption price on the next business day without any interest or other payment due to the delay.

In case an Event of Default shall have occurred and is continuing with respect to the Notes, the principal hereof may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Senior Indenture. The Senior Indenture provides that in certain circumstances such declaration and its consequences may be waived by the Holders of not less than a majority in aggregate principal amount of the Notes then Outstanding. However, any such consent or waiver by the Holder shall not affect any subsequent default or impair any right consequent thereon.

The Senior Indenture permits the Company and the Trustee, without the consent of the Holders of the Notes for certain situations and with the consent of not less than two-thirds of the Holders in aggregate principal amount of the Outstanding Notes of each series affected by such supplemental indenture in other situations, to execute supplemental indentures adding to, modifying, or changing various provisions of, the Senior Indenture; provided that no such supplemental indenture, without the consent of the Holder of each Outstanding Note affected thereby, shall (i) change the Stated Maturity of the principal of or any installment of interest on the Notes; (ii) reduce the principal amount thereof or the rate of interest thereon, or adversely

affect the right of repayment of any Holder; (iii) change the Place of Payment or Currency in which the principal of or interest on the Notes is payable, or impair the right to institute suit for the enforcement of any payment on or after the Stated Maturity thereof; (iv) reduce the percentage in principal amount of the Outstanding Notes, the consent of whose Holders is required for any such supplemental indenture, or the consent of whose Holders is required for any waiver (of compliance with certain provisions of the Senior Indenture or certain defaults thereunder and their consequences) provided for in the Senior Indenture, or reduce the requirements of Section 1504 for quorum or voting; or (v) modify any of the provisions of Sections 902, 513 or 1008 of the Senior Indenture, except to increase any such percentage or provide that certain other provisions of the Senior Indenture cannot be modified or waived without the consent of the Holder of each Outstanding Note affected thereby.

The Company may omit in any particular instance to comply with any term, provision or condition set forth in Section 1005, 1006 or 1007 of the Senior Indenture, if before the time it would have to comply, the Holders of at least a majority in principal amount of the Outstanding Notes, by act of such Holders, either shall waive such compliance in such instance or generally shall have waived compliance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect.

No reference herein to the Senior Indenture and no provision of this Security or of the Senior Indenture shall alter or impair the obligations of the Company, which are absolute and unconditional, to pay the principal of or interest on this Security at the respective times and at the rate herein prescribed.

The Notes are issuable in registered form without coupons in minimum denominations of $2,000 and in integral multiples of $1,000 in excess thereof. A Holder may exchange the Notes for a like aggregate principal amount of Notes of other authorized denominations in the manner and subject to the limitations provided in the Senior Indenture.

Upon due presentment for registration of transfer of the Notes at the office or agency for said purpose of the Company, a new Note or Notes of authorized denominations, for a like aggregate principal amount, will be issued to the transferee as provided in the Senior Indenture. No service charge shall be made for any such transfer, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto.

Prior to due presentation of this Security for registration of transfer, the Company, the Trustee, and any agent of the Company or the Trustee, may deem and treat the Holder hereof as the owner of this Security (whether or not any payment with respect to this Security shall be overdue), for the purpose of receiving payment of principal of and (subject to the provisions of the Senior Indenture) interest hereon and for all other purposes whatsoever, whether or not any payment with respect to this Security shall be overdue, and neither the Company, nor the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary.

No recourse shall be had for the payment of the principal of or interest on this Security, for any claim based hereon, or otherwise in respect hereof, or based on or in respect of the Senior Indenture or any indenture supplemental thereto, or because of the creation of any indebtedness represented thereby, against any incorporator, shareholder, officer or director, 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 the consideration for the issue hereof, expressly waived and released.

THIS SECURITY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

All terms used in this Security (and not otherwise defined in this Security) that are defined in the Senior Indenture shall have the meanings assigned to them in the Senior Indenture.

This Security is one of a duly authorized issue of debt securities of the Company, of the series hereinafter specified, all issued or to be issued under a Senior Indenture, dated as of November 1, 1996 (the “Base Indenture”), as supplemented by a First Supplemental Indenture, dated as of November 2, 2021 (the “Supplemental Indenture” and, together with the Base Indenture, the “Senior Indenture”) and each, duly executed and delivered by the Company to The Bank of New York Mellon Trust Company, N.A., formerly known as The Bank of New York Trust Company, N.A. (as successor to Harris Trust and Savings Bank), as trustee (hereinafter, the “Trustee”). Reference to the Senior Indenture and the Officer’s Certificate thereunder establishing the terms of this Security is hereby made for a description of the respective rights and duties thereunder of the Trustee, the Company and the Holders of the Securities. This Security is one of a series designated as the “5.247% Fixed-to-Floating Rate Senior Notes Due 2030” of the Company (hereinafter called the “Notes”), issued under the Senior Indenture. Each Holder by accepting a Note, agrees to be bound by all terms and provisions of the Senior Indenture, as amended from time to time, applicable to the Notes.

Neither the Senior Indenture nor the Notes limit or otherwise restrict the amount of indebtedness which may be incurred or other securities which may be issued by the Company. The Notes issued under the Senior Indenture are direct, unsecured obligations of the Company and will mature on July 26, 2030. The Notes rank on parity with all other unsecured, unsubordinated indebtedness of the Company.

The Company promises to pay interest on the principal amount of this Security (i) from and including July 27, 2022 to, but excluding, July 26, 2029 (the “Fixed Rate Period”), at a fixed rate of 5.247% per annum, semi-annually in arrears, on January 26 and July 26 of each year (each such date, a “Fixed Rate Interest Payment Date”), commencing on January 26, 2023 and ending on July 26, 2029, and (ii) from and including July 26, 2029 to but excluding the Stated Maturity (the “Floating Rate Period”), at an annual rate equal to the Base Rate (as defined and computed below) plus 2.600% (the “Spread”), quarterly in arrears, on the second Business Day (as defined below) following each Floating Rate Interest Period End-Date (as defined below) (each such Business Day, a “Floating Rate Interest Payment Date” and together with any Fixed Rate Period Payment Date, an “Interest Payment Date), until the principal hereof is paid or made available for payment.

Notwithstanding the above, the Floating Rate Interest Payment Date with respect to the final Floating Rate Interest Payment Period (as defined below) shall be the Stated Maturity.

The Company will pay interest to the holder in whose name this Security is registered at the close of business on the fifteenth calendar day (whether or not a Business Day (as defined below)), immediately preceding the related Fixed Rate Interest Payment Date or Floating Rate Interest Payment Period End-Date (as defined below), as applicable (such date being referred to herein as the “Regular Record Date”), except that the Company will pay interest at the Stated

Maturity or, if the Notes are redeemed, the Redemption Date to the person or persons to whom principal is payable.

During the Fixed Rate Period, interest shall be paid on the basis of a 360-day year comprised of twelve 30-day months. If any date on which interest is payable is not a Business Day, the payment of the interest payable on that date shall be made on the next day that is a Business Day without any interest or other payment in respect of the delay, with the same force and effect as if made on the date such payment were due, and no interest shall accrue on the amount payable for the period from and after such Fixed Rate Interest Payment Date.

During the Floating Rate Period, interest shall be paid on the basis of a 360-day year and the actual number of days elapsed.

For purposes of this Note, and in calculating the interest to be paid during the Floating Rate Period:

During the Floating Rate Period, the index maturity (the “Index Maturity”) for the Notes shall be daily.

During the Floating Rate Period, the Base Rate shall be SOFR (compounded daily over a quarterly Floating Rate Interest Payment Period in accordance with the specific formula described below). As further described below, (x) in determining the Base Rate for a U.S. Government Securities Business Day, the Base Rate generally will be the rate in respect of such day that is provided on the following U.S. Government Securities Business Day and (y) in determining the Base Rate for any other day, such as a Saturday, Sunday or holiday, the Base Rate generally will be the rate in respect of the immediately preceding U.S. Government Securities Business Day that is provided on the following U.S. Government Securities Business Day.

The “Spread” is the number of basis points (one one-hundredth of a percentage point) specified above to be added to the accrued interest compounding factor for a Floating Rate Interest Payment Period. The amount of interest accrued and payable on the Notes for the Floating Rate Interest Payment Period will be equal to the outstanding principal amount of the Notes multiplied by the product of: (x) the sum of the accrued interest compounding factor plus the Spread for the relevant Floating Rate Interest Payment Period, multiplied by (y) the quotient obtained by dividing the actual number of calendar days in such Floating Rate Interest Payment Period by 360.

Notwithstanding the foregoing, in no event will the interest rate payable for any Floating Rate Interest Payment Period be less than zero percent.

On the Floating Rate Interest Payment Date, accrued interest will be paid for the most recently completed Floating Rate Interest Payment Period. During the Floating Rate Period, interest on the Notes will accrue from and including the most recent Floating Rate Interest Payment Period End-Date to which interest has been paid or duly provided for, or from and including July 26, 2029 in the case of the first Floating Rate Interest Payment Period. Interest will accrue to but excluding the next Floating Rate Interest Payment Period End-Date.

During the Floating Rate Period, the calculation agent shall notify the paying agent of each determination of the interest rate applicable to the notes promptly after the determination is made.

With respect to any Floating Rate Interest Payment Period, the accrued interest compounding factor means the rate of return of a daily compound interest investment computed in accordance with the following formula (with the resulting percentage rounded, if necessary, to

the nearest one hundred-thousandth of a percentage point, with 0.000005 being rounded upwards to 0.00001):

Where:

“d₀”, for any Floating Rate Interest Payment Period, is the number of U.S. Government Securities Business Days in the relevant Floating Rate Interest Payment Period.

“i” is a series of whole numbers from one to d₀, each representing the relevant U.S. Government Securities Business Days in chronological order from, and including, the first U.S. Government Securities Business Day in the relevant Floating Rate Interest Payment Period.

“SOFRi”, for any day “i” in the relevant Floating Rate Interest Payment Period, is a reference rate equal to SOFR in respect of that day.

“n_i” is the number of calendar days in the relevant Floating Rate Interest Payment Period on which the rate is SOFR_i.

“d” is the number of calendar days in the relevant Floating Rate Interest Payment Period.

For these calculations, the interest rate in effect on any U.S. Government Securities Business Day will be the applicable rate as reset on that date, except that the level of SOFR for each calendar day in the period from and including the Rate Cut-Off Date to but excluding the Maturity Date will be the level of SOFR in respect of such Rate Cut-Off Date. The interest rate applicable to any other day is the interest rate from the immediately preceding U.S. Government Securities Business Day.

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

In connection with the SOFR definition above, the following definitions apply:

“Benchmark” means SOFR with the Index Maturity specified above; provided that if a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to SOFR with the Index Maturity specified above or the then-current Benchmark, then “Benchmark” means the applicable Benchmark Replacement.

“Benchmark Replacement” means the first alternative set forth in the order presented in clause (3) of the definition of “SOFR” that can be determined by the Company or its designee as of the Benchmark Replacement Date. In connection with the implementation of a Benchmark Replacement, the Company or its designee will have the right to make Benchmark Replacement Conforming Changes from time to time.

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

(1)    the Spread adjustment, or method for calculating or determining such Spread adjustment (which may be a positive or negative value or zero), 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, then the ISDA Fallback Adjustment;

“Benchmark Replacement Conforming Changes” means, with respect to any Benchmark Replacement, any technical, administrative or operational changes (including changes to the definition of “Floating Rate Interest Payment Periods,” timing and frequency of determining rates and making payments of interest and other administrative matters) that the Company or its designee decide may be appropriate to reflect the adoption of such Benchmark Replacement in a manner substantially consistent with market practice (or, if the Company or its designee decide that adoption of any portion of such market practice is not administratively feasible or if the Company or its designee determine that no market practice for use of the Benchmark Replacement exists, in such other manner as the Company or its designee determine is reasonably necessary).

“Benchmark Replacement Date” means the earliest to occur of the following events with respect to the then-current Benchmark:

(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:

“Corresponding Tenor” with respect to a Benchmark Replacement means a tenor (including overnight) having approximately the same length (disregarding business day adjustment) as the applicable tenor for the then-current Benchmark.

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

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

“New York Federal Reserve” means the Federal Reserve Bank of New York. “New York Federal Reserve’s Website” means the website of the New York Federal Reserve, currently at http://www.newyorkfed.org, or any successor source.

“Reference Time” with respect to any determination of the Benchmark means the time determined by the Company or its designee in accordance with the Benchmark Replacement Conforming Changes.

If a Benchmark Transition Event and its related Benchmark Replacement Date have occurred, any determination, decision or election that may be made by the Company or its designee pursuant to this section, including any determination with respect to a tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action or any selection:

None of the Trustee, the paying agent or the calculation agent shall be under any obligation (i) to monitor, determine or verify the unavailability or cessation of SOFR or the SOFR index, or whether or when there has occurred, or to give notice to any other transaction party of the occurrence of, any Benchmark Transition Event or related Benchmark Replacement Date, (ii) to select, determine or designate any Benchmark Replacement, or other successor or replacement benchmark index, or whether any conditions to the designation of such a rate or index have been satisfied, or (iii) to select, determine or designate any Benchmark Replacement Adjustment, or other modifier to any replacement or successor index, or (iv) to determine whether or what Benchmark Replacement Conforming Changes are necessary or advisable, if any, in connection with any of the foregoing, including, but not limited to, adjustments as to any alternative spread thereon, the business day convention, interest determination dates or any other relevant methodology applicable to such substitute or successor benchmark. In connection with the foregoing, each of the Trustee, paying agent and calculation agent shall be entitled to conclusively rely on any determinations made by the Company or its designee without independent investigation, and none will have any liability for actions taken at the Company’s direction in connection therewith.

None of the Trustee, the paying agent or the calculation agent shall be liable for any inability, failure or delay on its part to perform any of its duties set forth in this note as a result of the unavailability of SOFR, the SOFR index or other applicable Benchmark Replacement, including as a result of any failure, inability, delay, error or inaccuracy on the part of any other transaction party in providing any direction, instruction, notice or information required or contemplated by the terms of this note and reasonably required for the performance of such duties. None of the Trustee, paying agent or calculation agent shall be responsible or liable for the Company’s actions or omissions or for those of its designee, or for any failure or delay in the performance by the Company or its designee, nor shall any of the Trustee, paying agent or calculation agent be under any obligation to oversee or monitor the Company’s performance or that of its designee.

The Company will pay interest in such coin or currency of the United States of America as at the time of payment shall be legal tender for the payment of public and private debts. The

Company will make payments in respect of Notes in global form (including principal and interest) to the Holder thereof or a nominee of the Holder, by wire transfer of immediately available funds as of the close of business on the date such payments are due.

The term “Business Day” means any day that is not a Saturday or Sunday and that is not a day on which banks in New York, New York, Chicago, Illinois or McLean, Virginia are generally authorized or required by law or executive order to be closed.

If the Company defaults in the payment of interest due on any Interest Payment Date after taking into account any applicable grace period, such defaulted interest shall be paid as set forth in the Senior Indenture.

The Notes are not entitled to any sinking fund.

The Notes are subject to defeasance pursuant to Section 402 of the Senior Indenture.

The Notes are not convertible into common stock of the Company.

The Company may redeem the Notes (the date of such redemption, the “Redemption Date”) at its option on July 26, 2029 (which is the date that is one year prior to the Stated Maturity), in whole but not in part, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest thereon to the Redemption Date upon not less than 10 nor more than 60 days’ prior notice given to the holders of the Notes to be redeemed.

If money sufficient to pay the redemption price of and accrued interest on the Notes to be redeemed on the Redemption Date is deposited with the Trustee 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 such Notes called for redemption and such Notes will cease to be outstanding. If the Redemption Date is not a business day, the Company will pay the redemption price on the next business day without any interest or other payment due to the delay.

In case an Event of Default shall have occurred and is continuing with respect to the Notes, the principal hereof may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Senior Indenture. The Senior Indenture provides that in certain circumstances such declaration and its consequences may be waived by the Holders of not less than a majority in aggregate principal amount of the Notes then Outstanding. However, any such consent or waiver by the Holder shall not affect any subsequent default or impair any right consequent thereon.

The Senior Indenture permits the Company and the Trustee, without the consent of the Holders of the Notes for certain situations and with the consent of not less than two-thirds of the Holders in aggregate principal amount of the Outstanding Notes of each series affected by such supplemental indenture in other situations, to execute supplemental indentures adding to, modifying, or changing various provisions of, the Senior Indenture; provided that no such supplemental indenture, without the consent of the Holder of each Outstanding Note affected thereby, shall (i) change the Stated Maturity of the principal of or any installment of interest on the Notes; (ii) reduce the principal amount thereof or the rate of interest thereon, or adversely

affect the right of repayment of any Holder; (iii) change the Place of Payment or Currency in which the principal of or interest on the Notes is payable, or impair the right to institute suit for the enforcement of any payment on or after the Stated Maturity thereof; (iv) reduce the percentage in principal amount of the Outstanding Notes, the consent of whose Holders is required for any such supplemental indenture, or the consent of whose Holders is required for any waiver (of compliance with certain provisions of the Senior Indenture or certain defaults thereunder and their consequences) provided for in the Senior Indenture, or reduce the requirements of Section 1504 for quorum or voting; or (v) modify any of the provisions of Sections 902, 513 or 1008 of the Senior Indenture, except to increase any such percentage or provide that certain other provisions of the Senior Indenture cannot be modified or waived without the consent of the Holder of each Outstanding Note affected thereby.

The Company may omit in any particular instance to comply with any term, provision or condition set forth in Section 1005, 1006 or 1007 of the Senior Indenture, if before the time it would have to comply, the Holders of at least a majority in principal amount of the Outstanding Notes, by act of such Holders, either shall waive such compliance in such instance or generally shall have waived compliance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect.

No reference herein to the Senior Indenture and no provision of this Security or of the Senior Indenture shall alter or impair the obligations of the Company, which are absolute and unconditional, to pay the principal of or interest on this Security at the respective times and at the rate herein prescribed.

The Notes are issuable in registered form without coupons in minimum denominations of $2,000 and in integral multiples of $1,000 in excess thereof. A Holder may exchange the Notes for a like aggregate principal amount of Notes of other authorized denominations in the manner and subject to the limitations provided in the Senior Indenture.

Upon due presentment for registration of transfer of the Notes at the office or agency for said purpose of the Company, a new Note or Notes of authorized denominations, for a like aggregate principal amount, will be issued to the transferee as provided in the Senior Indenture. No service charge shall be made for any such transfer, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto.

Prior to due presentation of this Security for registration of transfer, the Company, the Trustee, and any agent of the Company or the Trustee, may deem and treat the Holder hereof as the owner of this Security (whether or not any payment with respect to this Security shall be overdue), for the purpose of receiving payment of principal of and (subject to the provisions of the Senior Indenture) interest hereon and for all other purposes whatsoever, whether or not any payment with respect to this Security shall be overdue, and neither the Company, nor the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary.

No recourse shall be had for the payment of the principal of or interest on this Security, for any claim based hereon, or otherwise in respect hereof, or based on or in respect of the Senior Indenture or any indenture supplemental thereto, or because of the creation of any indebtedness represented thereby, against any incorporator, shareholder, officer or director, 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 the consideration for the issue hereof, expressly waived and released.

THIS SECURITY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

All terms used in this Security (and not otherwise defined in this Security) that are defined in the Senior Indenture shall have the meanings assigned to them in the Senior Indenture.

McLean, Virginia 22102

Ladies and Gentlemen:

Capital One Financial Corporation, a Delaware corporation (the “Company”), has filed with the Securities and Exchange Commission a Registration Statement on Form S-3 (File No. 333-254191) (the “Registration Statement”) for the purpose of registering under the Securities Act of 1933, as amended (the “Securities Act”), certain securities, including $1,350,000,000 aggregate principal amount of its 4.985% Fixed-to-Floating Rate Senior Notes due 2026 and $900,000,000 aggregate principal amount of its 5.247% Fixed-to-Floating Rate Senior Notes due 2030 (collectively, the “Securities”). The Securities are to be issued pursuant to the provisions of the Senior Indenture dated as of November 1, 1996 (the “Base Indenture”) between the Company and The Bank of New York Mellon Trust Company, N.A., formerly known as The Bank of New York Trust Company, N.A. (as successor to Harris Trust and Savings Bank), as trustee (the “Trustee”), as supplemented by the first supplemental indenture dated as of November 2, 2021 between the Company and the Trustee (the “First Supplemental Indenture” and, together with the Base Indenture, the “Indenture”). The Securities are to be sold pursuant to the Underwriting Agreement dated July 25, 2022 (the “Underwriting Agreement”) among the Company and the several underwriters named therein (the “Underwriters”).

We, as your counsel, have examined originals or copies of such documents, corporate records, certificates of public officials and other instruments as we have deemed necessary or advisable for the purpose of rendering this opinion.

In rendering the opinion expressed herein, we have, without independent inquiry or investigation, assumed that (i) all documents submitted to us as originals are authentic and complete, (ii) all documents submitted to us as copies conform to authentic, complete originals, (iii) all signatures on all documents that we reviewed are genuine, (iv) all natural persons executing documents had and have the legal capacity to do so, (v) all statements in certificates of public officials and officers of the Company that we reviewed were and are accurate and (vi) all representations made by the Company as to matters of fact in the documents that we reviewed were and are accurate.

Based upon the foregoing, and subject to the additional assumptions and qualifications set forth below, we advise you that, in our opinion, when the Securities have been duly executed and authenticated in accordance with the provisions of the Indenture and delivered to and paid for by the Underwriters pursuant to the Underwriting Agreement, the Securities will constitute valid and binding obligations of the Company, enforceable in accordance with their terms, subject to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally, concepts of reasonableness and equitable principles of general applicability, provided that we express no opinion as to, (w) the enforceability of any waiver of rights under any usury or stay law, or (x) the validity, legally binding effect or enforceability of any provision that permits holders to collect any portion of stated principal amount upon acceleration of the Securities to the extent determined to constitute unearned interest.

In connection with the opinion expressed above, we have assumed that the Company is validly existing as a corporation in good standing under the laws of the State of Delaware. In addition, we have assumed that the Indenture and the Securities (collectively, the “Documents”) are valid, binding and enforceable agreements of each party thereto (other than as expressly covered above in respect of the Company). We have also assumed that the execution, delivery and performance by each party to each Document to which it is a party (a) are within its corporate powers, (b) do not contravene, or constitute a default under, the certificate of incorporation or bylaws or other constitutive documents of such party, (c) require no action by or in respect of, or filing with, any governmental body, agency or official and (d) do not contravene, or constitute a default under, any provision of applicable law or regulation or any judgment, injunction, order or decree or any agreement or other instrument binding upon such party, provided that we make no such assumption to the extent that we have specifically opined as to such matters with respect to the Company.

We are members of the Bar of the State of New York and the foregoing opinion is limited to the laws of the State of New York and the General Corporation Law of the State of Delaware, except that we express no opinion as to any law, rule or regulation that is applicable to the Company, the Documents or such transactions solely because such law, rule or regulation is part of a regulatory regime applicable to any party to any of the Documents or any of its affiliates due to the specific assets or business of such party or such affiliate.

We hereby consent to the filing 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 and further consent to the reference to our name under the caption “Validity of the Notes” in the prospectus supplement which is a part of the Registration Statement. In giving this consent, we do not admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act.

Very truly yours,

/s/ Davis Polk & Wardwell LLP
