PROSPECTUS SUPPLEMENT

(To prospectus dated March 11, 2024)

Capital One Financial Corporation

10,345,906 Shares

Common Stock

The selling security holders referred to in this prospectus supplement (the "selling security holders") may offer and sell up to 10,345,906 shares of our common stock, $0.01 par value per share ("common stock") under this prospectus supplement. We issued these shares of common stock to the selling security holders as consideration in connection with our acquisition of Brex Inc. ("Brex"), which closed on April 7, 2026. These shares of common stock were issued to the selling security holders pursuant to an Agreement and Plan of Merger and Reorganization, dated as of January 22, 2026 (as it may be amended, supplemented, restated or otherwise modified from time to time, the "Brex Merger Agreement"), by and among Capital One Financial Corporation, a Delaware corporation ("Capital One"), Brex, a Delaware corporation, Trilogy Merger Sub I, Inc., a Delaware corporation and a direct wholly owned subsidiary of Capital One ("Trilogy Merger Sub I"), Trilogy Merger Sub II, LLC, a Delaware limited liability company and a direct wholly owned subsidiary of Capital One ("Trilogy Merger Sub II"), and, solely for the limited purposes set forth therein, Fortis Advisors LLC, a Delaware limited liability company ("Fortis Advisors").

Our registration of the shares of common stock covered by this prospectus supplement does not mean that the selling security holders will offer or sell any of the shares. The common stock offered by the selling security holders may be sold from time to time through public or private transactions at market prices prevailing at the time of sale, at prices related to such market prices, at varying prices determined at the time of sale, at fixed prices, or at negotiated prices. The timing and amount of any sale is within the sole discretion of the selling security holder, subject to certain restrictions under applicable securities laws. See the section entitled "Plan of Distribution" beginning on page S-13 of this prospectus supplement for more information.

We are not selling any shares of common stock under the prospectus supplement and we will not receive any proceeds from any sale of shares of common stock by the selling security holders. Our common stock is listed on the New York Stock Exchange ("NYSE") under the trading symbol "COF." On April 22, 2026, the last reported sale price of our common stock was $199.43 per share.

Investing in our common stock involves risks. You should review carefully this prospectus supplement, the accompanying prospectus, the risks and uncertainties described in the section titled "Risk Factors" beginning on page S-7 of this prospectus supplement, as well as our other filings that are incorporated by reference into this prospectus supplement and the accompanying prospectus.

Neither the Securities and Exchange Commission (the "SEC") nor any state securities commission has approved or disapproved of these securities or determined if this prospectus supplement or the accompanying prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

The shares of common stock are not savings accounts, deposits or other obligations of a bank and are not insured or guaranteed by the Federal Deposit Insurance Corporation (the "FDIC") or any other governmental agency or instrumentality.

The date of this prospectus supplement is April 23, 2026.

SELLING SECURITY HOLDERS

This prospectus supplement relates to the offer and sale of up to 10,345,906 shares of our common stock previously issued to the selling security holders. We issued these shares of common stock to the selling security holders as consideration in connection with the Brex Transaction, which closed on April 7, 2026. These shares of common stock were issued to the selling security holders pursuant to the Brex Merger Agreement, as partial consideration for the Brex securities then-owned by the selling security holders. Additional selling security holders may be identified in one or more additional prospectus supplements.

Pursuant to the Brex Merger Agreement, we agreed to file with the SEC either a registration statement on Form S-3 (or if we were not at such time eligible to use Form S-3, a registration statement on Form S-1) or a resale prospectus supplement (together with any prospectus or amendment thereto, the "Resale Prospectus") under our existing automatic shelf registration statement on Form S-3 to provide for the public resale of the shares of our common stock issued at the closing in connection with the Brex Transaction (the "Registrable Securities"). We have agreed to use our best efforts to keep the Resale Prospectus continuously effective, and not subject to any stop order, injunction or other similar order or requirement of the SEC, until the earlier of (i) the first anniversary of the effectiveness of the filing of the Resale Prospectus, and (ii) the date that all Registrable Securities covered by the Resale Prospectus are (A) disposed of pursuant to the Resale Prospectus, (B) eligible for sale (without limitation as to volume or manner of sale) pursuant to Rule 144 under the Securities Act or (C) no longer outstanding. We have prepared this prospectus supplement to fulfill our requirements under the Brex Merger Agreement.

The shares of common stock being covered hereby may be sold or otherwise disposed of from time to time pursuant to this prospectus supplement or, on or following October 8, 2026 pursuant to Rule 144, by or for the account of the selling security holders provided such transactions meet the criteria and conform to the requirements of Rule 144. See the section entitled "Plan of Distribution" beginning on page S-12 of this prospectus supplement. This prospectus supplement does not cover subsequent sales of our common stock purchased from the selling security holders identified in this prospectus supplement.

The table below sets forth, to our knowledge, information as of the date of this prospectus supplement for the selling security holders and other information regarding the beneficial ownership of the shares of common stock held by the selling security holders. The second column lists the number of shares and percentage of common stock beneficially owned by the selling security holders as of April 20, 2026. The third column lists the maximum number of shares of common stock that may be sold or otherwise disposed of by the selling security holders pursuant to the registration statement to which this prospectus supplement relates. The fourth column lists the number of shares and percentage of common stock beneficially owned by the selling security holders upon completion of the offering contemplated hereby, assuming the sale of all shares of common stock that may be sold or otherwise disposed of by the selling security holders pursuant to this prospectus supplement. Notwithstanding the foregoing, the selling security holders may sell or otherwise dispose of some, all or none of their shares. We cannot predict when or in what amount the selling security holders may sell any of the shares offered in this prospectus supplement, if at all. The table, the related footnotes or additional disclosure below also set forth the nature of any position, office or, if applicable, any other material relationship that each selling security holder has had, within the past three years, with us or with any of our affiliates or their predecessors.

Pursuant to the rules and regulations of the SEC, beneficial ownership includes any shares of common stock as to which the selling security holders have sole or shared voting power or investment power and any shares of common stock that the selling security holders have the right to acquire within 60 days of the date of this prospectus supplement. We prepared the table based on information provided to us by the selling security holders. We have not in all cases sought to verify such information. Additionally, the selling security holders may have sold or transferred some or all of the shares of our common stock covered by this prospectus in transactions exempt from the registration requirements of the Securities Act since the date on which the information in the table was provided to us.

S-9

To our knowledge, except as may be disclosed herein, none of the selling security holders has, or within the past three years has had, any position, office or other material relationship with us or any of our affiliates, other than that certain of the selling security holders are or were employees or directors of Brex or its subsidiaries, certain of whom became employees of Capital One and its subsidiaries in connection with our acquisition of Brex. To our knowledge, except as may be disclosed herein, none of the selling security holders are broker-dealers, nor at the time of the acquisition did any selling security holders have direct or indirect agreements or understandings with any person to distribute any common stock.

PLAN OF DISTRIBUTION

The selling security holders may, from time to time, sell any or all of their shares of common stock offered herein (other than certain shares of common stock that remain subject to vesting conditions although we would not intend to include those shares in the shares that are registered under this prospectus supplement) pursuant to this prospectus supplement or, on or following October 8, 2026, pursuant to Rule 144 provided such transactions meet the criteria and conform to the requirements of Rule 144. We will not receive any of the proceeds from the sale by the selling security holders of the shares of common stock.

The selling security holders of our common stock and any of their pledgees, assignees, and successors-in-interest may, from time to time, sell any or all of their securities covered in this prospectus supplement on the principal trading market for our common stock or any other stock exchange, market, or trading facility on which our common stock is traded or in private transactions. These sales may be at market prices prevailing at the time of sale, at prices related to such market prices, at varying prices determined at the time of sale, at fixed prices, or at negotiated prices. The selling security holders may use any one or more of the following methods when selling securities:

On or after October 8, 2026, the selling security holders may also sell their shares of common stock under Rule 144 or any other exemption from registration under the Securities Act, if, when and to the extent such exemption is available to them at the time of such sale, rather than under this prospectus supplement. The selling security holders are not obligated to, and there is no assurance that the selling security holders will, sell all or any of the common stock we are registering hereunder.

Broker-dealers engaged by the selling security holders may arrange for other broker-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the selling security holders (or, if any broker-dealer acts as agent for the purchaser of common stock, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this prospectus supplement, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with Financial Industry Regulatory Authority, or FINRA, Rule 5110; and in the case of a principal transaction a markup or markdown in compliance with FINRA Rule 2121.

S-13

In connection with the sale of our common stock or interests in this prospectus supplement, the selling security holders may:

In addition, a selling security holder that is an entity may elect to make a pro rata in-kind distribution of securities to its members, partners or stockholders or purchase or redeem interests held in such entity by its members, partners or stockholders in exchange for securities, in each case pursuant to the registration statement of which this prospectus supplement is a part by delivering a prospectus with a plan of distribution. Such members, partners or stockholders (unless our affiliate) would thereby receive freely tradeable securities pursuant to the distribution. To the extent a distributee is an affiliate of ours (or to the extent otherwise required by law), we may file a prospectus supplement in order to permit the distributees to use the prospectus to resell the securities acquired in the distribution.

The selling security holders and any broker-dealers or agents that are involved in selling the securities may be deemed to be "underwriters" within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the securities purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act.

The shares of common stock covered in this prospectus supplement will be sold only through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the shares of common stock covered in this prospectus supplement may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the shares of common stock covered in this prospectus supplement may not simultaneously engage in market making activities with respect to our common stock for the applicable restricted period, as defined in Regulation M, prior to the commencement of the distribution. In addition, the selling security holders will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of our common stock by the selling security holders or any other person. We will make copies of this prospectus supplement and the accompanying prospectus available to the selling security holders and have informed them of the need to deliver a copy of this prospectus supplement and the accompanying prospectus to each purchaser at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act).

General corporate purposes may include repayment of debt, redemptions and repurchases of shares of our common stock and of our other securities, acquisitions, additions to working capital, capital expenditures and investments in our subsidiaries.

RISK FACTORS

Investing in our securities involves risks. Before you decide whether to purchase any of our securities, you should consider carefully the risks and other information in this prospectus and any accompanying prospectus supplement and carefully read the risks described in the documents incorporated by reference in this prospectus and any accompanying prospectus supplement, including the discussion under the "Risk Factors" section in our most recent Annual Report on Form 10-K and any subsequent Quarterly Report on Form 10-Q, as such discussion may be amended or updated in other reports filed by us with the SEC. If any of these risks were to materialize, it could adversely affect our business, results of operations, liquidity and financial condition and could cause the value of our securities to decline. If applicable, we will include in any prospectus supplement a description of significant additional risks specific to investing in the offering described therein.

DESCRIPTION OF DEBT SECURITIES

We may from time to time issue debt securities which will be our direct unsecured general obligations. These debt securities are described below and will be senior debt securities or subordinated debt securities and any senior or subordinated debt securities that may be part of a unit, all of which are called debt securities. The senior debt securities will be issued under an indenture between us 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 "senior debt trustee"), dated as of November 1, 1996 (the "senior debt indenture"), as supplemented by the first supplemental indenture between us and the senior debt trustee, dated as of November 2, 2021 (the "supplemental indenture" and together, with the senior debt indenture, the "senior indenture"), and the subordinated debt securities will be issued under an indenture between us and The Bank of New York Mellon Trust Company, N.A., as trustee (the "subordinated debt trustee" and together with the senior debt trustee, the "indenture trustees"), dated as of August 29, 2006 (the "subordinated indenture" and together with the senior indenture, the "indentures"), subject in each case to such amendments or supplemental indentures as may be adopted from time to time.

We have summarized selected provisions of the indentures below. The summary is not complete and does not describe every aspect of the indentures. A copy of each of the senior indenture and the subordinated indenture has been filed as an exhibit to the registration statement of which this prospectus is a part and has been qualified as an indenture under the Trust Indenture Act of 1939, as amended, or the Trust Indenture Act. You should read the more detailed provisions of the applicable indenture, including the defined terms, for provisions that may be important to you. You should also consider applicable provisions of the Trust Indenture Act. In the summary below, we have included references to section numbers so that you can easily locate these provisions. The particular terms of any debt securities we offer will be described in the related prospectus supplement, along with any applicable modifications of or additions to the general terms of the debt securities described below and in the indentures. For a description of the terms of any series of debt securities, you should also review both the prospectus supplement relating to that series and the description of the debt securities set forth in this prospectus before making an investment decision. Capitalized terms used in the summary have the meanings specified in the applicable indenture.

As of December 31, 2023, we had $31.2 billion in senior and subordinated notes outstanding that mature in varying amounts from 2024 to 2034, of which $27.5 billion in aggregate outstanding amount was senior debt securities and $3.7 billion in aggregate outstanding amount was subordinated debt securities. $431 million in senior and subordinated debt securities was issued by our principal operating subsidiary, Capital One, National Association ("CONA").

General

The debt securities will be our direct unsecured obligations. The indentures do not significantly limit our operations. In particular, they do not:

The senior debt securities will rank equally with all of our other unsecured unsubordinated indebtedness. The subordinated debt securities will have a position junior to all of our senior indebtedness.

8

Because we are a holding company, dividends and fees from our subsidiaries are our principal source of revenues from which to repay the debt securities. Our subsidiaries engaged in the banking or credit card business can only pay dividends if they are in compliance with applicable United States federal and state regulatory requirements. Our right to participate in any asset distribution of any of our subsidiaries, including CONA, on liquidation, reorganization or otherwise, will rank junior to the rights of all creditors of that subsidiary (except to the extent that we may ourselves be an unsubordinated creditor of that subsidiary). As a result, the rights of holders of debt securities to benefit from those distributions will also be junior to the rights of all creditors of our subsidiaries. Consequently, the debt securities will be effectively subordinated to all liabilities of our subsidiaries. CONA is subject to claims by creditors for long-term and short-term debt obligations, including deposit liabilities, obligations for federal funds purchased and securities sold under repurchase agreements. There are also various legal limitations on the extent to which CONA may pay dividends or otherwise supply funds to us or our other affiliates.

Terms

A prospectus supplement relating to the offering of any series of debt securities will include specific terms relating to the offering. These terms will include some or all of the following (unless specified otherwise or in context, section references are to sections of both the senior indenture and subordinated indenture):

9

Form of the Debt Securities

The indentures provide that we may issue senior and subordinated debt securities in registered form, in bearer form or in both registered and bearer form. Unless we indicate otherwise in the applicable prospectus supplement, each series of senior and subordinated debt securities will be issued in registered form, without coupons. Holders of "registered form" securities will be listed on the applicable indenture trustee's register for the applicable debt securities. (Sections 201 and 305)

Unless we indicate otherwise in the applicable prospectus supplement, we will issue senior and subordinated debt securities in registered form, without coupons, in denominations of $1,000 or any integral multiple of $1,000. Unless we indicate otherwise in the applicable prospectus supplement, we will issue senior and subordinated debt securities in bearer form in denominations of $5,000 or any integral multiple of $5,000. There will be no service charge for any registration of transfer, exchange, redemption, or conversion of senior and subordinated debt securities, but we or the applicable indenture trustee may require the holder to pay any tax or other governmental charge that may be imposed in connection with any registration of a transfer or exchange of the senior or subordinated debt securities, other than certain exchanges not involving any transfer. (Sections 302 and 305)

If we issue the debt securities in bearer form, the debt securities will have interest coupons attached. "Bearer form" securities are payable to whomever physically holds them from time to time. Debt securities in bearer form will not be offered, sold, resold or delivered in connection with their original issuance in the United States or to any United States person other than through offices of certain United States financial institutions located outside the United States. Purchasers of debt securities in bearer form will be subject to certification procedures and may be affected by United States tax law limitations. These procedures and limitations will be described in the applicable prospectus supplement.

Registration, Transfer, Payment and Paying Agent

Unless we indicate otherwise in the applicable prospectus supplement, payments on the debt securities will be made at our office or agency maintained for that purpose. We have appointed an agency in New York, New York to make payments on the debt securities; however, we may change our agent from time to time. Any transfer of the debt securities will be registerable at the same place. In addition, we may choose to pay interest by check mailed to the address in the security register of the person in whose name the debt security is registered at the close of business on the applicable record date. (Sections 1002 and 307)

10

Unless we indicate otherwise in the applicable prospectus supplement, any interest and any additional amounts with respect to any debt securities which is payable, but not punctually paid or duly provided for, may be paid to the holders as of a special record date fixed by the applicable indenture trustee or in any other lawful manner. (Section 307)

Unless we indicate otherwise in the applicable prospectus supplement, payments of principal of, premium, if any, and interest on debt securities in bearer form will be made at the office outside the United States specified in the applicable prospectus supplement and as we may designate from time to time. Payment can also be made by check or by transfer to an account maintained by the payee with a bank located outside the United States. Unless we indicate otherwise in the applicable prospectus supplement, payment on debt securities in bearer form will be made only if the holder surrenders the coupon relating to the interest payment date. We will not make any payments on any debt security in bearer form at any office or agency in the United States, by check mailed to any address in the United States or by transfer to any account maintained with a bank located in the United States. (Sections 1001 and 1002)

Global Debt Securities

Unless we indicate otherwise in the applicable prospectus supplement for a series of debt securities, each series of debt securities will be issued in global form, which means that we will deposit with the depositary identified in the applicable prospectus supplement (or its custodian) one or more certificates representing the entire series, as described below under "Book-Entry Procedures and Settlement." Global debt securities may be issued in either temporary or permanent form. (Sections 201 and 203)

The applicable prospectus supplement will describe any limitations and restrictions relating to a series of global senior or subordinated debt securities.

Covenants

Under the senior indenture, we agree to the following:

11

A "controlled subsidiary" is a significant subsidiary at least 80% of the voting stock of which is owned by us and/or one or more of our controlled subsidiaries.

The limitations described above do not apply to certain transactions required by law, rule, regulation or governmental order (including as a condition to an acquisition of another entity by us) or to any sale or transfer of assets in a securitization transaction.

Under the subordinated indenture, we agree to the following:

In addition, the senior indenture contains a covenant by us limiting our ability to create liens on the voting stock of a significant subsidiary. This covenant generally provides that, as long as any of the senior debt securities are outstanding, neither we nor any of our subsidiaries will create, assume or incur any pledge, encumbrance or lien, as security for indebtedness for borrowed money, upon a significant subsidiary's voting stock, or upon securities convertible into or options, warrants or rights to subscribe for or purchase, a significant subsidiary's voting stock, directly or indirectly, to secure indebtedness for borrowed money, if, treating such pledge, encumbrance or lien as a transfer of the significant subsidiary's voting stock or securities convertible into or options, warrants or rights to subscribe for or purchase the significant subsidiary's voting stock to the secured party (in each case after giving effect to such transaction and to the issuance of the maximum number of shares of voting stock of the significant subsidiary issuable upon the exercise of all such convertible securities, options, warrants or rights), the significant subsidiary would not continue to be a controlled subsidiary, unless the senior debt securities are equally and ratably secured with any and all such indebtedness by this pledge, encumbrance or lien. (Section 1006)

Subordination of Subordinated Debt Securities

Unless we indicate otherwise in the applicable prospectus supplement, the following provisions will apply to subordinated debt securities. Section references are to sections of the subordinated indenture.

Subordinated debt securities will be subordinated in right of payment to all "senior indebtedness," as defined below. Payments on subordinated debt securities also will be effectively subordinated if:

12

Because of this subordination, some of our creditors may receive more, ratably, than holders of subordinated debt securities if we are insolvent.

After all payments have been made to the holders of senior indebtedness, any holders of subordinated debt securities will be subrogated to the rights of holders of senior indebtedness to receive payments or distributions of cash, property or securities from us applicable to such senior indebtedness until all amounts owing on the subordinated debt securities have been paid in full. (Section 1602)

In addition, holders of subordinated debt securities may be fully subordinated to interests held by the U.S. government in the event that we enter into a receivership, insolvency, liquidation or similar proceeding.

"Senior indebtedness" includes: (1) the principal of, premium, if any, and interest on, whether outstanding now or incurred later, (a) all indebtedness for money borrowed by us, including indebtedness of others that we guarantee, other than the subordinated debt securities and the junior subordinated debt securities and other indebtedness that is expressly stated as not senior, and (b) any amendments, renewals, extensions, modifications and refundings of any indebtedness, unless in either case the instrument evidencing the indebtedness provides that it is not senior in right of payment to the subordinated debt securities; (2) all our capital lease obligations and any synthetic lease or tax retention operating lease; (3) all our obligations issued or assumed as the deferred purchase price of property, and all conditional sale or title retention agreements, but excluding trade accounts payable in the ordinary course of business; (4) all our obligations, contingent or otherwise, in respect of any letters of credit, bankers acceptances, security purchase facilities and similar credit transactions; (5) all our obligations in respect of interest rate swap, cap or similar agreements, interest rate future or options contracts, currency swap agreements, currency future or option contracts, commodity contracts and other similar agreements; (6) all obligations of the type referred to in clauses (1) through (5) of other persons for the payment of which we are responsible or liable as obligor, guarantor or otherwise; and (7) all obligations of the type referred to in clauses (1) through (6) of other persons secured by any lien on any of our property or assets whether or not such obligation is assumed by us.

Senior indebtedness does not include: (1) subordinated debt securities; (2) any indebtedness that by its terms is subordinated to, or ranks on an equal basis with, subordinated debt securities; and (3) any indebtedness between or among us and our affiliates, including (a) any junior subordinated debt securities, (b) trust preferred securities guarantees and (c) all other debt securities and guarantees in respect of those debt securities, issued to any trust, or a trustee of such trust, partnership or other entity affiliated with us which is our financing vehicle in connection with the issuance by such financing vehicle of trust preferred securities or other securities guaranteed by us pursuant to an instrument that ranks on an equal basis with, or junior to, the trust preferred securities guarantees.

Consolidation, Merger and Sale of Assets

Each indenture generally permits a consolidation or merger between us and another corporation and the conveyance, transfer or lease by us of all or substantially all of our property or assets, in each case without the consent of the holders of any outstanding debt securities, subject to certain requirements. Under each indenture, these transactions are permitted if:

13

Upon any consolidation, merger, conveyance, transfer or lease of this kind (other than, where permitted and described above in the case of the senior indenture, a conveyance, transfer or lease by us of all or substantially all of our assets to one or more of our subsidiaries where we own or control directly or indirectly more than 50% of the shares of voting stock), the successor shall be substituted for us as if it had been an original party to the indentures and the debt securities. Thereafter, such successor may exercise our rights and powers under the indentures and the debt securities and, except in the case of a lease, we will be released from all of our obligations and covenants under those documents. (Section 802)

Exchange of Debt Securities

Registered debt securities may be exchanged for an equal aggregate principal amount of registered debt securities of the same series containing identical terms and provisions in authorized denominations requested by the holders upon surrender of the registered debt securities at an office or agency that we maintain for that purpose and upon fulfillment of all other requirements set forth in the indentures. (Section 305)

Conversion and Exchangeability

The holders of debt securities that are convertible into our common stock or exchangeable into other securities will be entitled to convert or exchange the debt securities under some circumstances. The terms of any conversion or exchange will be described in the applicable prospectus supplement.

Events of Default; Covenant Breach

Events of Default

Unless we indicate otherwise in the applicable prospectus supplement for any series of debt securities, events of default with respect to any series of debt securities are:

14

If a default occurs with respect to any series of senior or subordinated debt securities, the applicable indenture trustee will give the holders of those debt securities notice of the default as and to the extent provided by the Trust Indenture Act and as described in the applicable indenture. (Section 501)

Covenant Breaches under the Senior Indenture

Under the senior indenture, any one of the following events constitutes a "covenant breach":

We may change, eliminate or add to the definition of "covenant breach" with respect to any particular series of senior debt securities, as indicated in the applicable prospectus supplement relating to such series. A covenant breach will not be an event of default with respect to any senior debt security except to the extent otherwise specified in or provided pursuant to, the senior indenture or a supplement thereto, with respect to such series of senior debt securities. (Section 101)

Remedies if an Event of Default or Covenant Breach Occurs

With respect to any series of senior debt securities, if an event of default occurs and continues, either the senior debt trustee or the holders of not less than 25% of the aggregate principal amount of the outstanding senior debt securities of that series may declare the principal amount (or such lesser amount as may be provided for the senior debt securities of such series) of all the senior debt securities of that series to be due and payable immediately by a notice in writing to the Company (and to the senior debt trustee if given by holders of such series of senior debt securities). Unless otherwise specified for a series of senior debt securities, there shall be no other rights of acceleration for such series of senior debt securities. In addition, for the avoidance of doubt, unless otherwise specified for a series of senior debt securities, neither the senior debt trustee nor holders of such series of senior debt securities shall have the right to accelerate the payment of such series of senior debt securities, nor shall the payment of any such series of senior debt securities be otherwise accelerated, as a result of a covenant breach. Furthermore, for the avoidance of doubt, if an event of default as described under the senior indenture is specified for a series of senior debt securities, there will be no right to accelerate payment of such series of senior debt securities unless such acceleration rights are granted specifically for such series of senior debt securities as contemplated by the senior debt indenture. (Section 502)

With respect to any series of subordinated debt securities, payment of the principal of such series of subordinated debt securities may be accelerated only in the case of certain events of bankruptcy, insolvency or reorganization of us or one of our major depositary institution subsidiaries. Subordinated debt securities cannot be accelerated if we default in our performance of any other covenant, including payment of principal or interest. (Section 502)

Any time after a declaration of acceleration has been made and before a judgment or decree for payment of the money due has been obtained the majority holders may, under certain circumstances, void the declaration.

15

"Majority holders" are the holders of a majority of the aggregate principal amount of outstanding senior or subordinated debt securities of that series. (Section 502)

The majority holders may direct the time, method and place of conducting any proceeding for any remedy available to the applicable indenture trustee, or exercising any trust or power conferred on the applicable indenture trustee, for the senior or subordinated debt securities of that series. (Section 512). The applicable indenture trustee generally is not obligated to exercise any of its rights or powers under any senior or subordinated indenture at the request or direction of any of the holders, unless those holders offer the applicable indenture trustee reasonable indemnity. (Section 601)

A holder does not have the right to institute a proceeding with respect to the indenture, for the appointment of a receiver or a trustee, or for any other remedy, unless:

However, these limitations do not apply to a suit for the enforcement of payment or conversion rights instituted on or after the respective due dates of the senior and subordinated debt securities of the applicable series. (Section 508)

Waivers of Certain Covenants and Past Defaults

The holders of not less than a majority of the aggregate principal amount of the outstanding senior and subordinated debt securities of each series may, on behalf of all holders of that series, waive our compliance with certain restrictive provisions of the applicable indenture. They also may waive any past default with respect to that series under the applicable indenture, except (1) a default in the payment of principal of, premium, if any, interest on or any additional amount, or (2) a default in the performance of certain covenants which cannot be modified without the consent of all of the holders of the applicable series. For purposes of this provision, a "default" means any event which is, or after notice or the lapse of time or both would become, an event of default, or, with respect to the senior indenture, an event of default or a covenant breach, with respect to the securities of such series. (Sections 513 and 1008)

Amendments to the Indentures

Supplemental Indentures with Consent of Holders

Unless we indicate otherwise in the applicable prospectus supplement, we and the applicable indenture trustee may modify or amend an indenture, with the consent of the holders of at least 66-2/3% in principal amount of each series of the senior or subordinated debt securities affected by the modification or amendment. However, no modification or amendment may, without the consent of each holder affected by the modification or amendment:

16

Supplemental Indentures without Consent of Holders

Except as otherwise provided in the applicable prospectus supplement, we and the applicable indenture trustee may modify and amend an indenture without the consent of any holder for any of the following purposes:

17

Legal Defeasance and Covenant Defeasance

If the applicable prospectus supplement provides for defeasance, we may at any time elect to defease and will be deemed to have paid and discharged our obligations on the applicable debt securities if:

In the case of a defeasance, the holders of the applicable debt securities of the series will not be entitled to the benefits of the applicable indenture, except for the registration of transfer or exchange and the replacement of stolen, lost or mutilated applicable debt securities and the requirements regarding the maintenance of an office or agency where the applicable debt securities can be surrendered for payment or registration of transfer or exchange and the right of the holders of the applicable debt securities to receive from the deposited funds payment of the principal of, premium, if any, interest on, and any additional amounts, if any, with respect to the applicable debt securities when due. (Section 402)

Determining the Outstanding Debt Securities

Unless otherwise provided in or pursuant to the applicable indenture, we will consider the following factors in determining whether the holders of the requisite principal amount of outstanding debt securities have given

18

any request, demand, authorization, direction, notice, consent or waiver under the applicable indenture or are present at a meeting of holders of debt securities for quorum purposes:

Governing Law

The indentures will be governed by, and construed in accordance with, the laws of the State of New York.

Regarding the Indenture Trustees

In the normal course of business, we and our subsidiaries conduct banking transactions with the indenture trustees, and the indenture trustees conduct banking transactions with us and our subsidiaries.

19

DESCRIPTION OF PREFERRED STOCK

Our Restated Certificate of Incorporation, dated July 26, 2023 (our "Restated Certificate of Incorporation"), authorizes our Board of Directors, or the Board, to create and provide for the issuance of one or more series of preferred stock, par value $.01 per share, without the approval of our stockholders. The Board can also determine the terms, including the designations, powers, preferences and rights (including conversion, voting and other rights) and the qualifications, limitations or restrictions, of any preferred stock. Currently, 50,000,000 shares of our authorized capital stock are classified as preferred stock under our Restated Certificate of Incorporation. As of December 31, 2023, 4,975,000 shares of preferred stock were issued and outstanding.

General

The following description summarizes the general terms and provisions of our authorized preferred stock. The particular terms of any series of preferred stock we offer will be described in the related prospectus supplement. You should read the particular terms of any series of preferred stock we offer described in the related prospectus supplement, together with the more detailed provisions of our Restated Certificate of Incorporation and the certificate of designation relating to the particular series of preferred stock, for provisions that may be important to you. Our Restated Certificate of Incorporation has been filed as an exhibit to the registration statement of which this prospectus is a part. The certificate of designation relating to the particular series of preferred stock will be filed as an exhibit to a document incorporated by reference in the registration statement. The prospectus supplement will also state whether any of the terms summarized below do not apply to the series of preferred stock being offered. Terms which could be included in a prospectus supplement include:

The preferred stock will, when issued, be fully paid and nonassessable and have no preemptive rights. Preferred stock will have the dividend, liquidation, and voting rights described below, unless we indicate otherwise in the applicable prospectus supplement relating to a particular series of preferred stock. You should read the prospectus supplement relating to any series of preferred stock for the series' specific terms.

Dividend Rights

Holders of preferred stock will receive, when, as and if declared by the Board, dividends at rates and on the dates described in the applicable prospectus supplement. Dividends must be declared by the Board out of legally available funds. Each dividend will be payable to the holders of record as they appear on our stock record books of the Corporation or, if applicable, the records of the depositary on the record dates fixed by the Board or its committee. Dividends on any series of preferred stock may be cumulative or noncumulative. The Corporation's

20

ability to pay dividends on the preferred stock depends on the ability of our subsidiaries, including CONA, to pay dividends to the Corporation. The ability of the Corporation and CONA to pay dividends in the future is subject to bank regulatory requirements and capital guidelines and policies established by the Federal Reserve Board and the Office of the Comptroller of the Currency, as well as the authority of the Federal Reserve Board, the Office of the Comptroller of the Currency and the Federal Deposit Insurance Corporation to limit the payment of dividends by the banking organizations they supervise (including the Company and CONA) if, in the banking regulator's opinion, payment of a dividend would constitute an unsafe or unsound practice in light of the financial condition of the banking organization.

We will not declare or pay or set apart funds for the payment of dividends on any securities which rank equally with the preferred stock unless we have paid or set apart funds for the payment of dividends on the preferred stock. If full dividends are not paid, the preferred stock will share dividends pro rata with any equally ranked securities.

Voting Rights

Unless we indicate otherwise in the applicable prospectus supplement relating to a particular series of preferred stock or expressly required by law, the holders of the preferred stock will not have any voting rights.

Rights upon Liquidation

If we liquidate, dissolve or wind up our affairs, either voluntarily or involuntarily, the holders of each series of preferred stock will be entitled to receive liquidation distributions. These will be in the amounts set forth in the applicable prospectus supplement, plus accrued and unpaid dividends and, if the series of the preferred stock is cumulative, accrued and unpaid dividends for all prior dividend periods. If we do not pay in full all amounts payable on any series of preferred stock, the holders of the preferred stock will share proportionately with any equally ranked securities in any distribution of our assets. After the holders of any series of preferred stock are paid in full, they will not have any further claim to any of our remaining assets. In addition, holders of preferred stock may be fully subordinated to interests held by the U.S. government in the event that we enter into a receivership, insolvency, liquidation or similar proceeding.

Because the Corporation is a holding company, the rights of its stockholders to participate in the assets of any subsidiary, including CONA, upon the subsidiary's liquidation or recapitalization may be subject to the prior claims of the subsidiary's creditors, except to the extent that the Corporation may itself be a creditor with recognized claims against the subsidiary.

Redemption

A series of preferred stock may be redeemable, in whole or in part, at our option or at the option of the holder of the stock, and may be subject to mandatory redemption pursuant to a sinking fund, under the terms described in any applicable prospectus supplement. Any redemption of preferred stock is subject to our receipt of any required prior approval by the Federal Reserve Board and to the satisfaction of any conditions set forth in the capital regulations and guidelines of the Federal Reserve Board applicable to the redemption of such series of preferred stock.

In the event of partial redemptions of preferred stock, the Board or its committee will determine the method for selecting the shares to be redeemed, which may be by lot or pro rata or by any other method the Board or its committee determines to be equitable.

On and after a redemption date, unless we default in the payment of the redemption price, dividends will cease to accrue on shares of preferred stock which were called for redemption. In addition, all rights of holders of the preferred shares will terminate except for the right to receive the redemption price.

21

Conversion and Exchange

The applicable prospectus supplement for any series of preferred stock will state the terms and conditions, if any, on which shares of that series are convertible into or exchangeable for our common stock or other securities, including:

22

DESCRIPTION OF COMMON STOCK

The Corporation is authorized to issue 1,000,000,000 shares of common stock, par value $.01 per share. As of December 31, 2023, 380,389,609 shares of common stock were issued and outstanding. The common stock is traded on the New York Stock Exchange under the symbol "COF." All outstanding shares of common stock are and will be fully paid and nonassessable.

The following summary is not complete, and you should refer to the applicable provisions of the Delaware General Corporation Law, our Restated Certificate of Incorporation and our Amended and Restated Bylaws, dated September 23, 2021 (our "Amended and Restated Bylaws"), for additional information. See "Where You Can Find More Information."

Voting and Other Rights

Each share of common stock is entitled to one vote on all matters submitted to a vote of stockholders. Except as otherwise provided by law, our Restated Certificate of Incorporation or our Amended and Restated Bylaws, a majority of the votes cast is required for all actions to be taken by stockholders. Directors in uncontested elections shall be elected by a majority of votes cast; however, in contested elections, a plurality standard shall apply. Stockholders do not have cumulative voting rights in the election of directors, which means that the holders of a majority of the votes cast in an election of directors can elect all of the directors. Shares of common stock also do not have any preemptive, subscription, redemption, sinking fund or conversion rights.

The foregoing rights may be subject to voting and other rights that we may grant from time to time to the holders of other classes of our securities.

For a more detailed description of the terms of these and similar rights granted to the holders of other classes of our securities, please refer to the applicable prospectus supplement for any offering of our common stock pursuant to this registration statement, to our Restated Certificate of Incorporation, and to the documents and other information that we incorporate by reference elsewhere in this prospectus. See "Where You Can Find More Information."

Distribution

To the extent outstanding preferred stock provides for a dividend preference, any dividends payable on our common stock are subject to such preference. Dividends must be declared by the Board out of legally available funds. If we liquidate, dissolve or wind up our affairs, common stockholders are entitled to share proportionately in the assets available for distribution to common stockholders.

Anti-Takeover Provisions of our Restated Certificate of Incorporation and our Amended and Restated Bylaws

Certain provisions in our Restated Certificate of Incorporation and our Amended and Restated Bylaws could make more difficult or discourage a tender offer, proxy contest or other takeover attempt that is opposed by the Board but which might be favored by the stockholders. Our Restated Certificate of Incorporation and our Amended and Restated Bylaws are filed as exhibits to the registration statement, and certain provisions are summarized below.

Board of Directors. Our Restated Certificate of Incorporation and our Amended and Restated Bylaws provide that, other than directors elected by any series of preferred stock, directors will be elected annually to one-year terms in office.

Number of Directors; Removal; Filling Vacancies. Our Amended and Restated Bylaws provide that our Board must consist of between three and seventeen directors, and vacancies will be filled only by the affirmative

23

vote of a majority of the remaining directors, even if less than a quorum remains in office, unless the Board determines otherwise. Therefore, unless our Amended and Restated Bylaws are further amended (or the Board determines otherwise), the Board could prevent any stockholder from enlarging the Board of Directors and filling the new directorships with the stockholder's own nominees.

Under Delaware law and our Restated Certificate of Incorporation, directors may be removed for or without cause. Our Restated Certificate of Incorporation also provides that directors may only be removed, whether for or without cause, upon the affirmative vote of holders of at least a majority of the voting power of the then-outstanding shares of stock entitled to vote generally in the election of directors, voting together as a single class.

Blank Check Preferred. Our Board is authorized, without stockholder approval, to create and provide for the issuance of up to an aggregate of 50,000,000 shares of preferred stock in series, to establish from time to time the number of shares to be included in each such series, and to fix the designations, powers, preferences and rights of the shares of each such series and the qualifications, limitations or restrictions on the shares of each such series.

The authority to designate preferred stock may be used to issue a series of preferred stock, or rights to acquire preferred stock, that could dilute the interest of, or impair the voting power of, holders of the common stock, or be used as a method of determining, delaying or preventing a change of control.

Stockholder Action by Written Consent; Special Meetings. Stockholder action can be taken only at an annual or special meeting of stockholders or by written consent in accordance with the applicable provisions set forth in our Restated Certificate of Incorporation and our Amended and Restated Bylaws. Under circumstances described in our Restated Certificate of Incorporation and our Amended and Restated Bylaws, special meetings of stockholders can be called by the Chair of the Board or by the Board pursuant to a resolution adopted by a majority of the authorized number of directors. Under our Restated Certificate of Incorporation, stockholders have the right to request that the Corporation call a special meeting of stockholders or to request that stockholder action be taken by written consent in lieu of a meeting, provided in each case that the requesting stockholders own 25% or more of the then-outstanding shares of stock entitled to vote on the matters proposed to be brought before the special meeting or the actions proposed to be taken by written consent, as applicable, and satisfy certain requirements set forth in our Restated Certificate of Incorporation and our Amended and Restated Bylaws. These requirements include a "net long" definition of stock ownership for purposes of determining whether stockholders requesting a special meeting or action by written consent satisfy the 25% ownership threshold, so that only stockholders with full and continuing economic interest and voting rights in our stock can request a special meeting or action by written consent. In addition, our Amended and Restated Bylaws set forth certain procedural requirements that the Board believes are appropriate to avoid duplicative or unnecessary special meetings or actions by written consent. Moreover, any special meeting of stockholders is limited to the business in the notice of the special meeting sent to the stockholders before the meeting, including any business stated in a valid special meeting request (in the case of a stockholder-requested special meeting).

The ability to take stockholder action by written consent or to request special meetings may be precluded if stockholders fail to satisfy the requirements in our Restated Certificate of Incorporation and our Amended and Restated Bylaws. You should refer to these documents for more information about the requirements.

Advance Notice Provisions for Stockholder Nominations and Stockholder Proposals. Only people who are nominated by, or at the direction of, the Board, or by a stockholder who has given proper written notice prior to a meeting at which directors are to be elected, will be eligible for election as directors. Business conducted at an annual meeting is limited to the business brought before the meeting by, or at the direction of, the Chair of the Board, the Board or a stockholder who has given proper notice. A stockholder's notice to us proposing to nominate a person for election as a director must contain certain information described in our Amended and Restated Bylaws and be submitted in compliance with the time frames specified in our Amended and Restated Bylaws.

24

You should refer to our Amended and Restated Bylaws for more information, including the process and timing requirements for a stockholder notice.

Some of the effects of the provisions described above and in our Amended and Restated Bylaws include:

Business Combinations. Under our Restated Certificate of Incorporation, certain mergers, share exchanges or sales of our assets with or to interested stockholders, as defined below, must be approved by the affirmative vote of the holders of at least a majority of the then-outstanding shares of stock entitled to vote generally in the election of directors, voting together as a single class, including the affirmative vote of a majority of such stock not owned directly or indirectly by any interested stockholder or any affiliate of any interested stockholder. Our Restated Certificate of Incorporation requires this affirmative vote even if no vote is required, or a lesser percentage is specified, by law or any national securities exchange or otherwise.

This majority affirmative vote is not required in two situations (and a business combination shall require only the vote required by law or any other applicable provision of our Restated Certificate of Incorporation). First, it is not required if the business combination has been approved by a majority of uninterested, continuing directors. Second, it is not required if certain price and procedure requirements designed to ensure that our stockholders receive a "fair price" for their common stock are satisfied. Our Restated Certificate of Incorporation defines an interested stockholder as any person, other than us or any of our subsidiaries, who or which:

Liability of Directors; Indemnification. A director generally will not be personally liable for monetary damages to us or our stockholders for breach of fiduciary duty as a director. A director may be held liable, however, for the following:

25

The Corporation indemnifies and advances expenses to our officers and directors in connection with legal proceedings to the fullest extent of the law. The Corporation may agree with any person to provide an indemnification greater than or different from the indemnification provided by our Restated Certificate of Incorporation or our Amended and Restated Bylaws.

Amendments. Our Restated Certificate of Incorporation may be amended with a majority vote of the stockholders. Our Restated Certificate of Incorporation provides that amendments to our Restated Certificate of Incorporation and our Amended and Restated Bylaws can be approved by a majority vote of the then-outstanding shares of stock entitled to vote generally in the election of directors. Our Restated Certificate of Incorporation includes a majority voting provision that applies to the amendment or repeal of, or the adoption of any provision inconsistent with, the provisions of our Restated Certificate of Incorporation related to business combinations, which can only be amended with an affirmative vote of the holders of at least a majority of the then-outstanding shares of stock entitled to vote generally in the election of directors, including the affirmative vote of the holders of a majority of the then-outstanding shares of such stock not owned directly or indirectly by any interested stockholder or any affiliate of any interested stockholder. Our Amended and Restated Bylaws generally may be amended by the Board or by the stockholders; provided that in the case of amendments by the stockholders the affirmative vote of at least a majority of the then-outstanding shares of stock entitled to vote generally in the election of directors is required. These vote requirements may have the effect of preventing a stockholder with less than a majority of the common stock from circumventing the requirements of our Amended and Restated Bylaws or a stockholder with only a majority of the common stock from circumventing certain provisions of our Restated Certificate of Incorporation by simply amending or repealing them.

Anti-Takeover Legislation

We have elected not to be subject to the provisions of Section 203 of the Delaware General Corporation Law. This provision generally states that, subject to some exceptions, a corporation cannot engage in any business combination with any "interested stockholder" for three years after the time that the stockholder became an interested stockholder unless the business combination is approved by the board of directors and authorized by the affirmative vote of at least 66-2/3% of the outstanding voting stock of the corporation which is not owned by the interested stockholder. Delaware law defines an interested stockholder to include any person, and its affiliates and associates, that owns 15% or more of the outstanding voting stock of the corporation, or that is an affiliate or associate of the corporation and was the owner of 15% or more of the outstanding voting stock of the corporation at any time within three years immediately prior to the relevant date. Business combinations are discussed more fully above.

Dividend Reinvestment Plan

Our dividend reinvestment and stock purchase plan (as amended and supplemented, the "DRIP Program") provides stockholders with the opportunity to purchase additional shares of our common stock by reinvesting all or a portion of their dividends on shares of common stock. It also provides existing stockholders with the option to make cash investments monthly, subject to certain limitations. We use proceeds from the DRIP Program for general corporate purposes.

Transfer Agent

The transfer agent and registrar for the common stock is Computershare Trust Company, N.A.

DESCRIPTION OF OTHER SECURITIES

We will set forth in the applicable prospectus supplement a description of any depositary shares, purchase contracts, warrants or units issued by us that may be offered pursuant to this prospectus.

27

RESALE BY SELLING SECURITYHOLDERS

Selling securityholders may use this prospectus in connection with offering our securities for resale. The applicable prospectus supplement will identify the selling securityholders and the terms of the securities offered for resale. Selling securityholders may be deemed to be underwriters in connection with the securities they resell and any profits on the resales may be deemed to be underwriting discounts and commissions under the Securities Act. The selling securityholders will receive all the proceeds from the resale of our securities. We will not receive any proceeds from resales by selling securityholders.

28

BOOK-ENTRY PROCEDURES AND SETTLEMENT

Unless we indicate otherwise in the applicable prospectus supplement, the debt securities, common stock, preferred stock, depositary shares or other securities described herein, which we refer to collectively as the securities, will be book-entry securities. All book-entry securities of the same issue initially will be represented by one or more fully registered global securities. Each global security will be deposited upon issuance with, or on behalf of, The Depository Trust Company, as depositary ("DTC"), and will be registered in the name of DTC or a nominee of DTC, in each case for credit to an account of a direct or indirect participant in DTC as described below. DTC will thus be the only registered holder of the securities and will be considered the sole owner of the securities for purposes of any indenture, warrant agreement, unit agreement, deposit agreement, purchase contract, or similar agreement governing the terms of such securities, as applicable, which we refer to as a governing agreement.

Global securities may be transferred, in whole and not in part, only to another nominee of DTC or to a successor of DTC or its nominee. Beneficial interests in the global securities may be held through the Euroclear System, or Euroclear, and Clearstream Banking, S.A., or Clearstream, each as indirect participants in DTC. Transfers of beneficial interests in the global securities will be subject to the applicable rules and procedures of DTC and its direct and indirect participants, including, if applicable, those of Euroclear and Clearstream, which may change from time to time. DTC has advised us as follows: it is a limited-purpose trust company organized under the New York Banking Law, a "banking organization" within the meaning of the New York Banking Law, a member of the Federal Reserve System, a "clearing corporation" within the meaning of the New York Uniform Commercial Code, and a "clearing agency" registered pursuant to the provisions of Section 17A of the Exchange Act. DTC holds and provides asset servicing for securities that its participants deposit with it. DTC also facilitates the post-trade settlement among participants of sales and other securities transactions in deposited securities through electronic computerized book entry transfers and pledges between participants' accounts, thereby eliminating the need for physical movement of securities certificates.

Direct participants in DTC's system include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations. Access to DTC's system also is available to others such as both U.S. and non-U.S. securities brokers and dealers, banks, trust companies and clearing corporations that clear through or maintain a custodial relationship with a direct participant, either directly or indirectly, which we collectively call indirect participants. Persons that are not participants may beneficially own securities held by or on behalf of DTC only through the participants or the indirect participants. The ownership interests in, and transfers of ownership interests in, each security held by or on behalf of DTC are recorded on the records of the participants and the indirect participants. The rules applicable to DTC and its participants are on file with the Securities and Exchange Commission. More information about DTC can be found at http://www.dtcc.com/ and http://www.dtc.org/.

DTC has also advised us that, upon the issuance of a global security evidencing any securities, it will credit, on its book-entry registration and transfer system, the respective principal or face amounts of the securities evidenced thereby to the designated accounts of participants. Ownership of beneficial interests in the global securities will be limited to participants or persons that may hold interests through participants. Ownership of beneficial interests in the global securities will be shown on, and the transfer of those ownership interests may be effected only through, records maintained by DTC or its nominee (with respect to participants) and the records of participants and indirect participants (with respect to other owners of beneficial interests in the global securities).

Investors in the global securities that are participants may hold their interests therein directly through DTC. Investors in the global securities that are not participants may hold their interests therein indirectly through organizations (including Euroclear and Clearstream) that are participants in such system. Euroclear and Clearstream will hold interests in the global securities on behalf of their participants through customers' securities accounts in their respective names on the books of their respective depositaries. All interests in a global security, including those held through Euroclear or Clearstream, may be subject to the procedures and

29

requirements of DTC. Those interests held through Euroclear or Clearstream may also be subject to the procedures and requirements of such systems.

The laws of some states require that certain purchasers of securities take physical delivery of those securities in definitive form. These laws may impair the ability of holders to transfer beneficial interests in global securities to certain purchasers. Because DTC can act only on behalf of the participants, which in turn act on behalf of the indirect participants, the ability of a person having beneficial interests in a global security to pledge such interests to persons that do not participate in the DTC system, or otherwise take actions in respect of such interests, may be affected by the lack of a physical certificate evidencing such interests.

So long as DTC or any successor depositary for a global security, or any nominee, is the registered holder of such global security, DTC or such successor depositary or nominee will be considered the sole owner or holder of the securities represented by such global security for all purposes under the governing agreement applicable to that global security. Except as set forth below, owners of beneficial interests in a global security will not be entitled to have the securities represented by such global security registered in their names, will not receive or be entitled to receive physical delivery of such securities in definitive form, and will not be considered the owners or holders thereof for any purpose under the governing agreement applicable to that global security. Accordingly, each person owning a beneficial interest in a global security must rely on the procedures of DTC and, if such person is not a participant, on the procedures of the participant through which such person owns its interest, to exercise any rights of a holder of securities under the governing agreement applicable to that global security. We understand that, under existing industry practices, in the event that we request any action of holders or that an owner of a beneficial interest in a global security desires to give any consent or take any action under the governing agreement applicable to that global security, DTC or any successor depositary would authorize the participants holding the relevant beneficial interests to give or take such action or consent, and such participants would authorize beneficial owners owning through such participants to give or take such action or consent or would otherwise act upon the instructions of beneficial owners owning through them.

Unless we indicate otherwise in the applicable prospectus supplement, any payments due with respect to any securities (including payments of principal and interest with respect to debt securities and dividends with respect to equity securities) that are registered in the name of or held by DTC or any successor depositary or nominee will be payable to DTC or such successor depositary or nominee, as the case may be, in its capacity as registered holder of the global securities representing the securities. Neither we, nor any trustee, registrar, paying agent or other agent in respect of the securities, nor any other agent of us or any such person will have any responsibility or liability for any aspect of the records relating to, or payments made on account of, beneficial ownership interests in the global securities, for maintaining, supervising or reviewing any records relating to such beneficial ownership interests, or for any other matter relating to the actions and practices of DTC or any of its participants or indirect participants.

We have been advised by DTC that its current practice, upon receipt of any payment in respect of a global security, is to credit participants' accounts with payments on the payment date, unless DTC has reason to believe it will not receive payments on such payment date. Each relevant participant is credited with an amount proportionate to its beneficial ownership of an interest in the principal or face amount of the relevant security as shown on the records of DTC. Payments by participants and indirect participants to owners of beneficial interests in a global security held through such participants and indirect participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in "street name," and will be the responsibility of such participants or indirect participants, and will not be the responsibility of us, any trustee, registrar, paying agent or other agent in respect of the securities, nor any agent of us or of any such person. Neither we nor any such person or agent will be liable for any delay by DTC or by any participant or indirect participant in identifying the beneficial owners of the securities, and we and any such person or agent may conclusively rely on and will be protected in relying on instructions from DTC or its nominee for all purposes.

30

Crossmarket transfers between the participants in DTC, on the one hand, and Euroclear or Clearstream participants, on the other hand, will be effected through DTC in accordance with DTC's rules on behalf of Euroclear or Clearstream, as the case may be, by its depositary; however, such cross-market transactions will require delivery of instructions to Euroclear or Clearstream, as the case may be, by the counterparty in such system in accordance with the rules and procedures and within the established deadlines (Brussels time) of such system. Euroclear or Clearstream, as the case may be, will, if the transaction meets its settlement requirements, deliver instructions to its respective depositary to take action to effect final settlement on its behalf by delivering or receiving interests in the relevant global security in DTC, and making or receiving payment in accordance with normal procedures for same- day funds settlement applicable to DTC. Euroclear participants and Clearstream participants may not deliver instructions directly to the depositories for Euroclear or Clearstream. DTC has advised us that it will take any action permitted to be taken by a holder of securities only at the direction of one or more participants to whose account DTC has credited the interests in the applicable global security and only in respect of such portion of the aggregate principal or face amount of the securities as to which such participant or participants has or have given such direction.

Except as provided in the applicable prospectus supplement, owners of beneficial interests in a global security will not be entitled to receive physical delivery of the related securities in certificated form and will not be considered the holders of the related securities for any purpose under the governing agreement applicable to that global security, and no global security will be exchangeable, except for another global security of the same denomination and tenor to be registered in the name of DTC or a successor depositary or nominee. Accordingly, each beneficial owner must rely on the procedures of DTC and, if the beneficial owner is not a participant, on the procedures of the participant or indirect participant through which the beneficial owner owns its interest to exercise any rights of a holder under the applicable governing agreement. However, if there is an event of default under any applicable governing agreement, DTC reserves the right to exchange the relevant global securities for securities in certificated form, and to distribute such securities to the participants.

Although DTC, Euroclear and Clearstream have agreed to the foregoing procedures to facilitate transfers of interests in the global securities among participants in DTC, Euroclear and Clearstream, they are under no obligation to perform or to continue to perform such procedures, and may discontinue such procedures at any time. Neither we, nor any indenture trustee, nor any agent of us or of any such person will have any responsibility for the performance by DTC, Euroclear or Clearstream or their respective participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

The information in this section, including any description of the operations and procedures of DTC, Euroclear and Clearstream, has been provided solely as a matter of convenience. We do not take any responsibility for the accuracy of this information, and this information is not intended to serve as a representation, warranty or contract modification of any kind. The operations and procedures of DTC, Euroclear and Clearstream are solely within the control of such settlement systems and are subject to changes by them. We urge investors to contact such systems or their participants directly to discuss these matters.
