The distribution of this prospectus supplement and the accompanying prospectus and the offering of the notes in certain jurisdictions may be restricted by law. Persons outside the United States who receive this prospectus supplement and the accompanying prospectus should inform themselves about and observe any such restrictions. This prospectus supplement and the accompanying prospectus do not constitute, and may not be used in connection with, an offer or solicitation by anyone in any jurisdiction in which such offer or solicitation is not authorized or in which the person making such offer or solicitation is not authorized or in which the person making such offer or solicitation is not qualified to do so or to any person to whom it is unlawful to make such offer or solicitation.

Notice to Prospective Investors in the European Economic Area

Neither this prospectus supplement nor the accompanying prospectus is a prospectus for the purposes of Regulation (EU) 2017/1129 (as amended, the “Prospectus Regulation”).

PRIIPs Regulation / Prohibition of sales to EEA retail investors

The notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area (the “EEA”). For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, “MiFID II”); or (ii) a customer within the meaning of Directive (EU) 2016/97 (as amended, the “Insurance Distribution Directive”), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II.

Consequently, no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling the notes or otherwise making them available to retail investors in the EEA has been prepared and, therefore, offering, or selling the notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

MiFID II Product Governance / Professional Investors and ECPs Only Target Market

Solely for the purposes of each manufacturer’s product approval process, the target market assessment in respect of the notes has led to the conclusion that: (i) the target market for the notes is eligible counterparties and professional clients only, each as defined in MiFID II, and (ii) all channels for distribution of the notes to eligible counterparties and professional clients are appropriate. Any person subsequently offering, selling, or recommending the notes (a “distributor”) should take into consideration the manufacturers’ target market assessment; however, a distributor subject to MiFID II is responsible for undertaking its own target market assessment in respect of the notes (by either adopting or refining the manufacturers’ target market assessment) and determining appropriate distribution channels.

The notes are not being offered or sold to any person in the United Kingdom except in circumstances which will not result in an offer of securities to the public in the United Kingdom within the meaning of Part VI of the FSMA.

UK PRIIPs Regulation / Prohibition of sales to UK retail investors

The notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold, or otherwise made available to any retail investor in the United Kingdom. For the purposes of this provision, a “retail investor” means a person who is one (or more) of: (i) a retail client, as defined in point (8) of Article 2 of Regulation (EU) No 2017/565 as it forms part of domestic law by virtue of the European Union (Withdrawal) Act 2018 (the “EUWA”); or (ii) a customer within the meaning of the provisions of the FSMA, and any rules or regulations made under the FSMA to implement Directive (EU) 2016/97, where that customer would not qualify as a professional client, as defined in point (8) of Article 2(1) of Regulation (EU) No 600/2014 as it forms part of domestic law by virtue of the EUWA (“UK MiFIR”). Consequently, no key information document required by Regulation (EU) No 1286/2014 as it forms part of domestic law by virtue of the EUWA (the “UK PRIIPs Regulation”) for offering or selling the notes or otherwise making them available to retail investors in the United Kingdom has been prepared and, therefore, offering or selling the notes or otherwise making them available to any retail investor in the United Kingdom may be unlawful under the UK PRIIPs Regulation.

UK MiFIR product governance / Professional investors and ECPs only target market

Solely for the purposes of each manufacturer’s product approval process, the target market assessment in respect of the notes has led to the conclusion that: (i) the target market for the notes is only eligible counterparties, as defined in the FCA Handbook Conduct of Business Sourcebook (the “COBS”), and professional clients, as defined in UK MiFIR, and (ii) all channels for distribution of the notes to eligible counterparties and professional clients are appropriate. Any person subsequently offering, selling, or recommending the notes (a “distributor”) should take into consideration the manufacturers’ target market assessment; however, a distributor subject to the FCA Handbook Product Intervention and Governance Sourcebook (the “UK MiFIR Product Governance Rules”) is responsible for undertaking its own target market assessment in respect of the notes (by either adopting or refining the manufacturers’ target market assessment) and determining appropriate distribution channels.

You may obtain a copy of the documents incorporated by reference by following the instructions in the section entitled “Where You Can Find More Information” in this prospectus supplement.

Our Business

Our mission is to make it easier for everyone to experience the world. We aim to provide consumers with a best-in-class experience offering the travel choices they want, with tailored planning, payment, language, and other options, seamlessly connecting them with our travel service provider partners. We offer these services through five primary consumer-facing brands: Booking.com, Priceline, Agoda, KAYAK, and OpenTable:

Accommodations

Ground
Transportation

Flights

Activities

Restaurants

Meta Search

Booking.com

Priceline

Agoda

KAYAK

OpenTable

We derive substantially all of our revenues from providing online travel reservation services, which facilitate online travel purchases by travelers from travel service providers (which we generally refer to as “consumers” and “partners,” respectively). We also earn revenues from advertising services, restaurant reservation and management services, travel-related insurance offerings, and other services.

For the year ended December 31, 2024 and the nine months ended September 30, 2025, we had revenues of $23.7 billion and $20.6 billion, respectively, which we classify as “merchant” revenues, “agency” revenues, and “advertising and other” revenues.

•

Merchant revenues are derived from transactions where we facilitate payments from travelers for the services provided, generally at the time of booking. These include transactions where travelers book accommodation, rental car, airline reservations, and other travel related services. Merchant revenues include travel reservation commissions and transaction net revenues (i.e., the amount charged to travelers, including the contra-revenue impact of merchandising, less the amount owed to travel service providers); revenues from facilitation of payments such as credit card processing rebates and customer processing fees; and ancillary fees, including travel-related insurance revenues. The majority of our merchant revenue is from Booking.com’s accommodation reservations.

•

Agency revenues are derived from travel-related transactions where we do not facilitate payments from travelers for the services provided. Agency revenues consist almost entirely of travel reservation commissions from our reservation services. Substantially all of our agency revenue is from Booking.com’s accommodation reservations.

•

Advertising and other revenues are derived primarily from (a) revenues earned by KAYAK for sending referrals to online travel companies and travel service providers and for advertising placements on our platforms, and (b) revenues earned by OpenTable for its restaurant reservation services and subscription fees for restaurant management services.

Our common stock is listed on The Nasdaq Global Select Market under the symbol “BKNG.” Our principal executive offices are located at 800 Connecticut Avenue, Norwalk, Connecticut 06854.

TABLE OF CONTENTS

RISK FACTORS

Investing in the notes involves risks. Before purchasing any notes, you should carefully consider the specific factors discussed below, together with all the other information contained in this prospectus supplement, the accompanying prospectus, and the documents incorporated and deemed to be incorporated by reference herein and therein.

The risks described in this prospectus supplement, the accompanying prospectus, and the documents incorporated and deemed to be incorporated by reference herein and therein are not the only risks that we face. Additional risks and uncertainties not currently known to us or that we currently deem immaterial may also impair our business operations. Any of these risks may have a material adverse effect on our business, financial condition, results of operations and cashflows. In such a case, you may lose all or part of your investment in the notes. For a further discussion of the risks, uncertainties, and assumptions relating to our business, please see the discussion under the caption “Risk Factors” included in our Annual Report on Form 10-K for the year ended December 31, 2024, as updated by quarterly and other reports and documents we file with the SEC and that are incorporated by reference in this prospectus supplement and the accompanying prospectus.

Risks Relating to the Notes

The notes will be effectively subordinated to any secured indebtedness that we may incur.

The notes will be our general senior unsecured obligations and will rank equally in right of payment with all our other senior unsecured indebtedness, including our other outstanding series of senior unsecured notes and any borrowings under our revolving credit facility. The notes will be effectively subordinated, however, to any secured debt we incur to the extent of the value of the assets securing such debt. As of the date of this prospectus supplement, we had no secured indebtedness outstanding. Although the indenture governing the notes contains certain limitations on our ability to incur secured indebtedness, it nevertheless permits us to incur a significant amount of secured indebtedness.

In the event that we are declared bankrupt, become insolvent, or are liquidated or reorganized, any debt that ranks ahead of the notes will be entitled to be paid in full from our assets before any payment may be made with respect to the notes. Holders of the notes will participate ratably with all holders of our unsecured indebtedness that is deemed to be of the same class as the notes, and potentially with all of our other general creditors, based upon the respective amounts owed to each holder or creditor, in our assets that secure secured debt only after all such secured debt has been repaid in full from the proceeds of such assets. In any of the foregoing circumstances, there may not be sufficient assets to pay amounts due on the notes. As a result, holders of the notes may receive less, ratably, than holders of secured indebtedness.

We may incur additional indebtedness ranking equal to the notes.

The indenture governing the notes does not contain any financial or operating covenants that would prohibit or limit us or our subsidiaries from incurring additional indebtedness and other liabilities, paying dividends, or issuing securities or repurchasing securities issued by us or any of our subsidiaries. The incurrence of additional indebtedness could adversely affect our ability to pay our obligations on the notes. We anticipate that from time to time we will incur additional indebtedness in the future.

If we incur additional indebtedness that ranks equally in right of payment with the notes, including trade payables, the holders of that debt will be entitled to share ratably with you in any proceeds distributed in connection with our insolvency, liquidation, reorganization, dissolution, or other winding-up. This may have the effect of reducing the amount of proceeds paid to you.

The notes will be structurally subordinated to the indebtedness and other liabilities of our subsidiaries.

The notes will be a senior unsecured obligation of Booking Holdings Inc. A significant portion of our assets consists of direct and indirect ownership interests in, and our business is conducted through, our subsidiaries. As a consequence, the notes will be structurally subordinated to existing and future indebtedness and other liabilities and commitments (including trade payables) of our subsidiaries. Our subsidiaries are

S-5

TABLE OF CONTENTS

separate legal entities that have no obligation to pay any amounts due under the notes or to make any funds available therefor, whether by dividends, loans, or other payments. Our right to participate in any distribution of assets of any subsidiary upon its liquidation or reorganization or otherwise, and the ability of holders of the notes to benefit indirectly from any such distribution, is subject to the prior claims of creditors of that subsidiary, except to the extent we are recognized as a creditor of that subsidiary. All obligations of our subsidiaries will have to be satisfied before any of the assets of such subsidiaries would be available for distribution, upon a liquidation or otherwise. As of September 30, 2025, the aggregate amount of liabilities of our consolidated subsidiaries, excluding intercompany liabilities, was approximately $16.0 billion.

The notes do not have an established trading market, which may negatively affect their market value and your ability to transfer or sell your notes.

Each series of the notes is a new issue of securities with no established trading market. We intend to apply to list the notes on Nasdaq, but Nasdaq may not accept the notes for listing. Even if the notes are approved for listing by Nasdaq, an active trading market on Nasdaq for the notes may never develop or, if it develops, may not last, in which case the trading price of the notes could be adversely affected and your ability to transfer your notes will be limited. If an active trading market does develop on Nasdaq, the notes may trade at prices lower than the offering price. The trading price of the notes will depend on many factors, including:

•

prevailing interest rates;

•

the market for similar securities;

•

general economic and financial market conditions;

•

our issuance of debt or preferred equity securities; and

•

our financial condition, results of operations, and prospects.

We have been advised by the underwriters that they intend to make a market in the notes pending any listing of the notes on Nasdaq, but they are not obligated to do so and may discontinue market-making at any time without notice.

Ratings of the notes may change, which could affect the market price and marketability of the notes.

Our debt securities are subject to periodic review by one or more independent credit rating agencies, and may be subject to rating and periodic review by additional independent credit rating agencies in the future. Any such ratings are limited in scope, and do not address all material risks relating to an investment in the notes, but rather reflect only the view of the rating agency at the time the rating is issued. An explanation of the significance of such rating may be obtained from such rating agency. We cannot assure you that such credit rating will remain in effect for any given period of time or that any such rating will not be lowered, suspended, or withdrawn entirely by the rating agency, if, in such rating agency’s judgment, circumstances so warrant. It is also possible that any such rating may be lowered in connection with future events, such as future acquisitions. Holders of the notes will have no recourse against us or any other parties in the event of a change in or suspension or withdrawal of any such rating. Any lowering, suspension, or withdrawal of such ratings may have an adverse effect on the market prices or marketability of the notes.

An increase in market interest rates could result in a decrease in the market value of the notes.

The condition of the financial markets and prevailing interest rates have fluctuated significantly in the past and are likely to fluctuate in the future. In general, as market interest rates rise, debt securities bearing interest at fixed rates of interest decline in value. Consequently, if you purchase notes and market interest rates increase, the market value of those notes may decline. We cannot predict the future level of market interest rates.

Redemption prior to maturity may adversely affect your return on the notes.

Because the notes are redeemable at our option, we may choose to redeem your notes at times when prevailing interest rates are relatively low. As a result, you generally will not be able to reinvest the redemption

proceeds in a comparable security at an effective interest rate that is as high as the interest rate on your notes being redeemed. See “Description of Notes — Optional Redemption.”

An investment in the notes by a purchaser whose home currency is not euro entails significant risks.

All payments of interest on and the principal of the notes and any redemption price for the notes will be made in euro. An investment in the notes by a purchaser whose home currency is not euro entails significant risks. These risks include the possibility of significant changes in rates of exchange between the holder’s home currency and euro and the possibility of the imposition or subsequent modification of foreign exchange controls. These risks generally depend on factors over which we have no control, such as economic, financial, and political events and the supply of and demand for the relevant currencies. In the past, rates of exchange between euro and certain currencies have been highly volatile, and each holder should be aware that volatility may occur in the future. Fluctuations (or lack thereof) in any particular exchange rate that have occurred in the past, however, are not necessarily indicative of fluctuations (or lack thereof) in the rate that may occur during the term of the notes. Depreciation of euro against the holder’s home currency would result in a decrease in the effective yield of the notes below its coupon rate and, in certain circumstances, could result in a loss to the holder.

The notes permit us to make payments in U.S. dollars if we are unable to obtain euro.

If euro is unavailable to us due to the imposition of exchange controls or other circumstances beyond our control or if euro is no longer being used by the then member states of the European Monetary Union that have adopted euro as their currency or for the settlement of transactions by public institutions of or within the international banking community, then all payments in respect of the notes will be made in U.S. dollars until euro is again available to us or so used. The amount payable on any date in euro will be converted into U.S. dollars at the rate mandated by the U.S. Federal Reserve Board as of the close of business on the second business day prior to the relevant payment date or, if the U.S. Federal Reserve Board has not mandated a rate of conversion, on the basis of the then most recently available market exchange rate for euro, determined by us in our sole discretion. Any payment in respect of the notes so made in U.S. dollars will not constitute an event of default under the notes or the indenture governing the notes. Investors will be subject to foreign exchange risks as to payment of principal and interest that may have important economic and tax consequences for them.

In a lawsuit for payment on the notes, an investor may bear currency exchange risk.

The indenture is, and the notes will be, governed by the laws of the State of New York. Under New York law, a New York state court rendering a judgment on the notes would be required to render the judgment in euro. The judgment would be converted into U.S. dollars, however, at the exchange rate prevailing on the date of entry of the judgment. Consequently, in a lawsuit for payment on the notes, investors would bear currency exchange risk until a New York state court judgment is entered. A U.S. federal court sitting in New York with diversity jurisdiction over a dispute arising in connection with the notes would apply the foregoing New York law.

In courts outside of New York, investors may not be able to obtain a judgment in a currency other than U.S. dollars. For example, a judgment for money in an action based on the notes in many other U.S. federal or state courts ordinarily would be enforced in the United States only in U.S. dollars. The date used to determine the rate of conversion of euro into U.S. dollars would depend upon various factors, including which court renders the judgment and when the judgment is rendered.

DESCRIPTION OF NOTES

You can find the definitions of certain terms used in the following summary under the subheading “— Certain Definitions.” For purposes of this description of notes, references to “Booking,” the “Company,” “we,” “our,” and “us” refer only to Booking Holdings Inc. and not to any of its subsidiaries.

Booking will issue the notes under an indenture, dated as of August 8, 2017 (the “indenture”), between itself and U.S. Bank Trust Company, National Association (as successor in interest to U.S. Bank National Association), as trustee. The terms of the notes include those stated in the indenture and those made part of the indenture by reference to the Trust Indenture Act of 1939, as amended.

The following description is a summary of the material provisions of the indenture and the notes. It does not restate the indenture in its entirety. We urge you to read the indenture, because it, and not this description, defines your rights as a holder of the notes. A copy of the indenture has been filed as an exhibit to our shelf registration statement on Form S-3 filed with the SEC on August 4, 2023. You may also request copies of the indenture at our address set forth under the heading “Where You Can Find More Information” in this prospectus supplement.

The 20 Notes will mature on , 20 , unless earlier redeemed or repurchased by us.

The indenture does not limit the amount of debt that may be issued by us or our subsidiaries under the indenture or otherwise. Our subsidiaries will not guarantee any of our obligations under the notes. Our operations are conducted through our subsidiaries and, therefore, we depend on the cash flow of our subsidiaries to meet our obligations, including our obligations under the notes. The notes will be structurally subordinated to the existing and future indebtedness and other liabilities and commitments (including trade payables) of our subsidiaries. Any right we have to receive assets of any of our subsidiaries upon the subsidiary’s liquidation or reorganization (and the consequent right of the holders of the notes to participate in those assets) will be structurally subordinated to the claims of that subsidiary’s creditors, except to the extent that we are recognized as a creditor of the subsidiary. As of September 30, 2025, the aggregate amount of liabilities of our consolidated subsidiaries, excluding intercompany liabilities, was approximately $16.0 billion, to which the notes would be effectively subordinated. See “Risk Factors — Risks Relating to the Notes — The notes will be structurally subordinated to the indebtedness and other liabilities of our subsidiaries.” In the event of our bankruptcy, liquidation, reorganization, or other winding up, our assets

that secure secured debt will be available to pay obligations on the notes only after all indebtedness under such secured debt has been repaid in full from the proceeds of such assets, and there may not be sufficient assets remaining to pay amounts due on the notes then outstanding. See “Risk Factors — Risks Relating to the Notes — The notes will be effectively subordinated to any secured indebtedness that we may incur.”

The notes will be issued only in denominations of €100,000 and integral multiples of €1,000 in excess thereof. We use the term “note” in this prospectus supplement to refer to each €1,000 principal amount of notes.

We may, without the consent of the holders, issue additional notes of any series under the indenture in the future with the same terms (except for the issue date, price to public, and, if applicable, the initial interest payment date) and with the same CUSIP number as the other notes of such series in an unlimited aggregate principal amount; provided that if any such additional notes are not fungible with such series of notes for U.S. federal income tax purposes, such additional notes will have a separate CUSIP number. We may also from time to time repurchase the notes of any series in tender offers, open market purchases, or negotiated transactions without prior notice to holders.

The registered holder of a note will be treated as the owner of it for all purposes.

Other than restrictions described under “— Certain Covenants” below, the indenture does not contain any covenants or other provisions designed to afford holders of the notes protection in the event of a highly leveraged transaction involving us or in the event of a decline in our credit rating as the result of a takeover, recapitalization, highly leveraged transaction, or similar restructuring involving us that could adversely affect holders.

Each series of notes is a new issue of securities with no established trading market. We intend to file an application to list each series of notes on Nasdaq. The listing applications will be subject to approval by Nasdaq. If the applications are approved, trading of the notes on Nasdaq is expected to begin within 30 days after the original issue date of the notes. If the applications are approved, we will have no obligation to maintain such listing, and we may delist the notes at any time.

Issuance in Euro

All payments of interest and principal, including payments made upon any redemption of the notes, will be made in euro; provided that if euro is unavailable to us due to the imposition of exchange controls or other circumstances beyond our control or if euro is no longer being used by the then member states of the European Monetary Union that have adopted euro as their currency or for the settlement of transactions by public institutions of or within the international banking community, then all payments in respect of the notes will be made in U.S. dollars until euro is again available to us or so used. The amount payable on any date in euro will be converted into U.S. dollars at the rate mandated by the U.S. Federal Reserve Board as of the close of business on the second business day prior to the relevant payment date or, if the U.S. Federal Reserve Board has not mandated a rate of conversion, on the basis of the most recently available market exchange rate for euro, as determined in our sole discretion. Any payment in respect of the notes so made in U.S. dollars will not constitute an Event of Default under the notes or the indenture governing the notes. Neither the trustee nor the paying agent shall have any responsibility for any calculation or conversion in connection with the forgoing.

Investors will be subject to foreign exchange risks as to payments of principal and interest that may have important economic and tax consequences to them. See “Risk Factors — Risks Relating to the Notes.”

As of November 3, 2025, the euro/U.S. $ exchange rate was €1.00 = U.S. $1.15090, as reported by Bloomberg L.P. as of 9:00 a.m., New York time.

Payments on the Notes; Paying Agent and Registrar

We have initially designated U.S. Bank Europe DAC, UK Branch as our paying agent and U.S. Bank Trust Company, National Association as our registrar and transfer agent where notes may be presented for payment. We may, however, change the paying agent or registrar without prior notice to the holders of the notes but with prior written notice to the trustee, and we may act as paying agent or registrar. If we issue

S-10

TABLE OF CONTENTS

notes in definitive form, interest on such notes will be payable (1) to holders holding an aggregate principal amount of notes of €1.0 million or less, by check mailed to the holders of those notes, and (2) to holders holding an aggregate principal amount of notes of more than €1.0 million, either by check mailed to each holder or, upon application by a holder to the registrar not later than the relevant record date, by wire transfer in immediately available funds to that holder’s account, which application shall remain in effect until the holder notifies the registrar, in writing, to the contrary.

We will pay the principal of and interest on notes in global form registered in the name of or held by Euroclear or Clearstream or their respective nominees in immediately available funds to Euroclear or Clearstream or their respective nominees, as the case may be, as the registered holder of such global notes.

Transfer and Exchange

A holder of notes may transfer or exchange notes at the office of the registrar in accordance with the indenture. The registrar and/or the trustee may require a holder, among other things, to furnish appropriate endorsements and transfer documents. No service charge will be imposed by us, the trustee, or the registrar for any registration of transfer or exchange of notes, but we may require a holder to pay a sum sufficient to cover any transfer tax or other similar governmental charge required by law or permitted by the indenture.

Interest

The 20 Notes will bear interest at a rate of % per annum from , 2025, or from the most recent date to which interest has been paid or duly provided for. Interest on the 20 Notes will be payable annually in arrears on of each year, beginning , 2026. The 20 Notes will bear interest at a rate of % per annum from , 2025, or from the most recent date to which interest has been paid or duly provided for. Interest on the 20 Notes will be payable annually in arrears on of each year, beginning , 2026.

Interest will be paid to the person in whose name a note is registered at the close of business on the immediately preceding the relevant interest payment date. Interest on the notes will be computed on the basis of the actual number of days in the period for which interest is being calculated and the actual number of days from and including the last date on which interest was paid on the applicable series of notes (or , 2025 if no interest has been paid on such notes), to but excluding the next scheduled interest payment date. This payment convention is referred to as Actual/Actual (ICMA) as defined in the rulebook of the International Capital Market Association.

If any interest payment date, the maturity date, or any earlier required repurchase date upon a designated event falls on a day that is not a business day, the required payment will be made on the next succeeding business day and no interest on such payment will accrue in respect of the delay. The term “business day” means any day, other than a Saturday or Sunday, (1) that is not a day on which banking institutions in the City of New York or London are authorized or required by law or executive order to close, and (2) on which the real time gross settlement system operated by Eurosystem (the T2 system), or any successor thereto, is open.

Optional Redemption

On and after the applicable Par Call Date, we may redeem the notes of the applicable series in whole or in part, at our option at any time or from time to time, at a redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest thereon, if any, to, but excluding, the date of redemption.

Prior to the applicable Par Call Date, we may redeem the notes of the applicable series in whole or in part, at our option at any time or from time to time, at a redemption price equal to the greater of (1) 100% of the principal amount of the notes to be redeemed, and (2) an amount equal to the sum of the present values of the remaining scheduled payments of principal and interest thereon that would have been payable in respect of such notes calculated as if the maturity date of such notes was the applicable Par Call Date, not including any portion of the payments of interest accrued to the redemption date, discounted to such redemption date on an annual basis at the Comparable Government Bond Rate, plus basis points with

S-11

TABLE OF CONTENTS

respect to the 20 Notes and basis points with respect to the 20 Notes, plus, in the case of each of (1) and (2), accrued and unpaid interest on the notes of the applicable series, if any, to, but excluding, such redemption date.

For purposes of calculating the redemption prices, the following terms will have the meanings set forth below.

“Comparable Government Bond Rate” means the yield to maturity, expressed as a percentage (rounded to three decimal places, with 0.0005 being rounded upwards) on the third business day prior to the date fixed for redemption of the Comparable Government Bond (as defined below) on the basis of the middle market price of such Comparable Government Bond prevailing at 11:00 a.m. (London time) on such business day as determined by an independent investment bank.

“Comparable Government Bond” means, in relation to any Comparable Government Bond Rate calculation, at the discretion of an independent investment bank selected by us, a German government bond whose maturity is closest to the Par Call Date, or if such independent investment bank in its discretion determines that such similar bond is not in issue, such other German government bond as such independent investment bank may, with the advice of three brokers of, and/or market makers in, German government bonds selected by us, determine to be appropriate for determining the Comparable Government Bond Rate.

“Par Call Date” means, with respect to the 20 Notes, , 20 (the date that is months prior to the maturity date of the 20 Notes) and, with respect to the 20 Notes, , 20 (the date that is months prior to the maturity date of the 20 Notes).

If less than all of the notes of a series are to be redeemed, in the case of certificated notes and global notes, the trustee will select notes for redemption in accordance with the procedures of the depositary. The trustee, in the case of certificated notes and global notes, shall select notes and portions of notes in amounts of €100,000 and integral multiples of €1,000 in excess thereof.

Notice of any redemption will be sent electronically or, at our option, mailed at least 10 days but not more than 60 days before the redemption date, except that a redemption notice may be delivered more than 60 days prior to the redemption date if such notice is issued in connection with legal or covenant defeasance of the Company’s obligations or a satisfaction and discharge of the indenture, or if the redemption date is delayed as provided for in the following paragraph. We may provide in any redemption notice that payment of the redemption price and the performance of our obligations with respect to such redemption may be performed by another Person. We will not be responsible for giving notice to anyone other than the depositary. Unless we default in payment of the redemption price, on or after the redemption date, interest will cease to accrue on the notes called for redemption.

Any redemption of notes or notice thereof may, at our discretion, be subject to the satisfaction (or waiver by us, in our sole discretion) of one or more conditions precedent. If such redemption or notice is subject to satisfaction of one or more conditions precedent, such notice may state that, in our discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied (or waived by us in our sole discretion), or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been (or, in our sole determination, may not be) satisfied (or waived by us in our sole discretion) by the redemption date, or by the redemption date so delayed.

The notes are also subject to redemption prior to maturity if certain events occur involving U.S. taxation. If any of these special tax events occurs, the notes will be redeemed at a redemption price of 100% of their principal amount plus accrued and unpaid interest to, but not including, the date fixed for redemption, and additional amounts, if any. See “— Redemption for Tax Reasons.” Before the redemption date, we will deposit with the paying agent money sufficient to pay the redemption price of and accrued and unpaid interest to, but not including, the redemption date on the notes to be redeemed on such date, and additional amounts, if any.

Payment of Additional Amounts

All payments of principal and interest on the notes by us will be made free and clear of and without withholding or deduction for or on account of any present or future tax, assessment or other governmental

S-12

TABLE OF CONTENTS

charge imposed by the United States (or any political subdivision or taxing authority thereof or therein having power to tax), unless the withholding or deduction of such taxes, assessment, or other government charge is required by law or the official interpretation or administration thereof. We will, subject to the exceptions and limitations set forth below, pay as additional interest on the notes such additional amounts as are necessary in order that the net payment by us of the principal of and interest on the notes to a holder who is not a United States person (as defined below), after withholding or deduction for any present or future tax, assessment, or other governmental charge imposed by the United States (or any political subdivision or taxing authority thereof or therein having power to tax), will not be less than the amount provided in the notes to be then due and payable; provided, however, that the foregoing obligation to pay additional amounts shall not apply:

(1) to the extent any tax, assessment, or other governmental charge is imposed by reason of the holder (or the beneficial owner for whose benefit such holder holds such note), or a fiduciary, settlor, beneficiary, member, or shareholder of the holder if the holder is an estate, trust, partnership, or corporation, or a person holding a power over an estate or trust administered by a fiduciary holder, being considered as:

a) being or having been engaged in a trade or business in the United States or having or having had a permanent establishment in the United States;

b) having a current or former connection with the United States (other than a connection arising solely as a result of the ownership of the notes, the receipt of any payment, or the enforcement of any rights hereunder), including being or having been a citizen or resident of the United States;

c) being or having been a personal holding company, a passive foreign investment company, or a controlled foreign corporation for United States income tax purposes or a corporation that has accumulated earnings to avoid U.S. federal income tax;

d) being or having been a “10-percent shareholder” of the Company as defined in section 871(h)(3) of the United States Internal Revenue Code of 1986, as amended (the “Code”), or any successor provision; or

e) being or having been a bank receiving payments on an extension of credit made pursuant to a loan agreement entered into in the ordinary course of its trade or business, as described in section 881(c)(3)(A) of the Code or any successor provision;

(2) to any holder that is not the sole beneficial owner of the notes, or a portion of the notes, or that is a fiduciary, partnership, or limited liability company, but only to the extent that a beneficial owner with respect to the holder, a beneficiary, or settlor with respect to the fiduciary, or a beneficial owner or member of the partnership or limited liability company would not have been entitled to the payment of an additional amount had the beneficiary, settlor, beneficial owner, or member received directly its beneficial or distributive share of the payment;

(3) to the extent any tax, assessment, or other governmental charge would not have been imposed but for the failure of the holder or any other person to comply with certification, identification, or information reporting requirements concerning the nationality, residence, identity or connection with the United States of the holder or beneficial owner of the notes, if compliance is required by statute, by regulation of the United States or any taxing authority therein, or by an applicable income tax treaty to which the United States is a party as a precondition to exemption from such tax, assessment or other governmental charge;

(4) to any tax, assessment, or other governmental charge that is imposed otherwise than by withholding or deduction by us or a paying agent from the payment;

(5) to any estate, inheritance, gift, sales, transfer, wealth, capital gains, or personal property tax or similar tax, assessment, or other governmental charge, or excise tax imposed on the transfer of notes;

(6) to the extent any tax, assessment or other governmental charge would not have been imposed but for the presentation by the holder of any note, where presentation is required, for payment on a date

S-13

TABLE OF CONTENTS

more than 30 days after the date on which payment became due and payable or the date on which payment thereof is duly provided for, whichever occurs later;

(7) to any tax, assessment, or other governmental charge imposed under Sections 1471 through 1474 of the Code (or any amended or successor provisions), any current or future regulations or official interpretations thereof, any agreement entered into pursuant to Section 1471(b) of the Code or any fiscal or regulatory legislation, rules or practices adopted pursuant to any intergovernmental agreement entered into in connection with the implementation of such sections of the Code; or

(8) in the case of any combination of items (1), (2), (3), (4), (5), (6), and (7).

The notes are subject in all cases to any tax, fiscal, or other law or regulation or administrative or judicial interpretation applicable to the notes. Except as specifically provided under this heading “— Payment of Additional Amounts,” we will not be required to make any payment for any tax, assessment, or other governmental charge imposed by any government or a political subdivision or taxing authority of or in any government or political subdivision.

As used under this heading “— Payment of Additional Amounts” and under the heading “— Redemption for Tax Reasons,” the term “United States” means the United States of America, the states of the United States, and the District of Columbia, and the term “United States person” means any individual who is a citizen or resident of the United States for U.S. federal income tax purposes, a corporation, partnership, or other entity created or organized in or under the laws of the United States, any state of the United States or the District of Columbia, or any estate or trust the income of which is subject to U.S. federal income taxation regardless of its source.

Redemption for Tax Reasons

If, as a result of any change in, or amendment to, the laws (or any regulations or rulings promulgated under the laws) of the United States (or any taxing authority in the United States), or any change in, or amendment to, an official position regarding the application or interpretation of such laws, regulations, or rulings, which change or amendment is announced or becomes effective on or after the date of this prospectus supplement, we become or, based upon a written opinion of independent counsel selected by us, will become obligated to pay additional amounts as described herein under the heading “— Payment of Additional Amounts” with respect to the notes of a series, then we may at any time at our option redeem, in whole, but not in part, such series of notes on not less than 30 nor more than 60 days prior notice, at a redemption price equal to 100% of their principal amount, together with accrued and unpaid interest on those notes to, but not including, the date fixed for redemption.

No Sinking Fund

The notes will not be entitled to the benefit of any sinking fund.

Certain Covenants

The indenture will contain covenants including, among others, the following:

Limitation on Liens

The Company will not, and will not permit any Restricted Subsidiary to, directly or indirectly, incur or permit to exist any Lien securing Indebtedness (the “Initial Lien”) on any of its properties or assets, whether owned at the Issue Date or thereafter acquired, other than Permitted Liens, without effectively providing that the notes (together with, at the option of the Company, any other Indebtedness of the Company or any of its Subsidiaries ranking equally in right of payment with the notes) are secured equally and ratably with (or prior to) the obligations so secured for so long as such obligations are so secured.

Notwithstanding the foregoing, the Company and its Restricted Subsidiaries may create, assume, incur, or guarantee Indebtedness secured by a Lien without equally and ratably securing the notes; provided that at the time of such creation, assumption, incurrence, or guarantee, after giving effect thereto and to the retirement of any Indebtedness that is being retired substantially concurrently with any such creation,

S-14

TABLE OF CONTENTS

assumption, incurrence, or guarantee, the sum of (a) the aggregate amount of all outstanding Indebtedness of the Company and its Restricted Subsidiaries secured by Liens other than Permitted Liens and (b) the Attributable Debt associated with all Sale/Leaseback Transactions of the Company and its Restricted Subsidiaries permitted by the last paragraph under “— Limitation on Sale/Leaseback Transactions” below, does not at such time exceed the greater of (i) 20% of the Consolidated Net Tangible Assets of the Company measured at the date of incurrence of the Lien, and (ii) $3.0 billion.

Any such Lien thereby created in favor of the notes will be automatically and unconditionally released and discharged upon (i) the release and discharge of each Initial Lien to which it relates, or (ii) any sale, exchange, or transfer to any Person not an affiliate of the Company of the property or assets secured by such Initial Lien.

Limitation on Sale/Leaseback Transactions

The Company will not, and will not permit any Restricted Subsidiary to, enter into any Sale/Leaseback Transaction with respect to any property unless:

(1)

the Company or such Restricted Subsidiary would be entitled to create a Lien on such property securing the Attributable Debt associated with such Sale/Leaseback Transaction without equally and ratably securing the notes pursuant to the covenant described under “— Limitation on Liens”;

(2)

the net proceeds of the sale of the property to be leased are at least equal to such property’s fair market value, as determined by the Company’s board of directors, and the proceeds are applied within 365 days of the effective date of the Sale/Leaseback Transaction to the purchase, construction, development, or acquisition of assets or to the repayment of any Indebtedness of the Company that ranks equally with the notes or any Indebtedness of one or more Restricted Subsidiaries; provided that the amount required to be applied to the repayment of any such Indebtedness pursuant to this clause (2) shall be reduced by the principal amount of any notes delivered within 365 days after such sale to the trustee for retirement and cancellation;

(3)

such transaction was entered into prior to the Issue Date;

(4)

such transaction involves a lease for not more than three years (or which may be terminated by the Company or a Restricted Subsidiary within a period of not more than three years);

(5)

such transaction was for the sale and lease between only the Company and a Subsidiary of the Company or only between Subsidiaries of the Company; or

such transaction involves a sale and lease of property executed by the time of, or within 18 months after the latest of, the acquisition, the completion of construction or improvement, or the commencement of commercial operation of the property.

Notwithstanding the restrictions outlined in the preceding paragraph, the Company and its Restricted Subsidiaries will be permitted to enter into Sale/Leaseback Transactions, without complying with the requirements of the preceding paragraph, if, after giving effect thereto, the aggregate amount of all Attributable Debt associated with Sale/Leaseback Transactions not otherwise permitted by the preceding paragraph that is outstanding at such time, together with the aggregate amount of all outstanding Indebtedness secured by Liens permitted under the second paragraph under “— Limitation on Liens” above, does not exceed the greater of (i) 20% of the Consolidated Net Tangible Assets of the Company measured at the date of the Sale/Leaseback Transactions, and (ii) $3.0 billion.

Merger and Consolidation

The indenture provides that we will not consolidate with or merge with or into, or convey, transfer, or lease all or substantially all of our properties and assets to, another person, unless (i) the resulting, surviving, or transferee person, if not the Company, is a person organized and existing under the laws of the United States of America, any state thereof, or the District of Columbia; (ii) immediately after giving effect to such transaction, no default has occurred and is continuing under the indenture; and (iii) the resulting, surviving, or transferee person, if not the Company, expressly assumes by supplemental indenture all of our obligations

S-15

TABLE OF CONTENTS

under the notes and the indenture. Upon any such consolidation, merger, or transfer, the resulting, surviving, or transferee person shall succeed to, and may exercise every right and power of, the Company under the indenture.

Events of Default

An “Event of Default” with respect to a series of notes is defined in the indenture as:

(1) default in any payment of interest on any note of such series when due and payable and the default continues for a period of 30 days;

(2) default in the payment of principal of any note of such series when due and payable at its stated maturity, upon acceleration, or otherwise;

(3) failure by us to comply with our obligations under “— Certain Covenants — Merger and Consolidation”;

(4) failure by us for 60 days after written notice from the trustee or the holders of at least 25% in principal amount of the notes of such series then outstanding has been received to comply with any of our other covenants or agreements contained in the notes of such series or indenture;

(5) default by us or any majority owned subsidiary in the payment of the principal or interest on any mortgage, agreement, or other instrument under which there may be outstanding, or by which there may be secured or evidenced, any debt for money borrowed in excess of $100 million in the aggregate of the Company and/or any subsidiary, whether such debt now exists or shall hereafter be created, which default results in such debt becoming or being declared due and payable, and such acceleration shall not have been rescinded or annulled within 30 days after written notice of such acceleration has been received by us or such subsidiary; or

(6) certain events of bankruptcy, insolvency, or reorganization (the “bankruptcy provisions”) of the Company or any of our significant subsidiaries as defined in Rule 1-02 of Regulation S-X promulgated by the SEC as in effect on the date of the indenture.

If an Event of Default with respect to any series of notes occurs and is continuing, the trustee by notice to us, or the holders of at least 25% in principal amount of the outstanding notes of such series by written notice to us and the trustee, may, and the trustee at the written request of such holders shall, declare 100% of the principal of and accrued and unpaid interest on all the notes of such series to be due and payable. Upon such a declaration, such principal and accrued and unpaid interest will be due and payable immediately. Upon an Event of Default arising out of the bankruptcy provisions, however, the aggregate principal amount and accrued and unpaid interest will be due and payable immediately.

The holders of a majority in principal amount of the outstanding notes of a series may waive an existing default (except with respect to nonpayment of principal or interest or certain other matters) and may rescind any acceleration with respect to the notes of such series and its consequences if (1) rescission would not conflict with any judgment or decree of a court of competent jurisdiction, and (2) all existing Events of Default, other than the nonpayment of the principal of and interest on the notes of such series that have become due solely by such declaration of acceleration, have been cured or waived.

Subject to the provisions of the indenture relating to the duties of the trustee, if an Event of Default occurs and is continuing, the trustee will be under no obligation to exercise any of the rights or powers under the indenture at the request or direction of any of the holders unless such holders have offered to the trustee indemnity and/or security satisfactory to it against any loss, liability, or expense. Except to enforce the right to receive payment of principal or interest when due, no holder may pursue any remedy with respect to the indenture or the notes of a series unless:

(1)

such holder has previously given the trustee notice that an Event of Default is continuing;

(2)

holders of at least 25% in principal amount of the outstanding notes of such series have requested the trustee in writing to pursue the remedy;

S-16

TABLE OF CONTENTS

(3)

such holders have offered the trustee security and/or indemnity satisfactory to it against any loss, liability, or expense;

(4)

the trustee has not complied with such request within 60 days after the receipt of the request and the offer of security and/or indemnity; and

(5)

the holders of a majority in principal amount of the outstanding notes of such series have not given the trustee a direction that is inconsistent with such request within such 60-day period.

Subject to certain restrictions, the holders of a majority in principal amount of the outstanding notes of a series are given the right to direct the time, method, and place of conducting any proceeding for any remedy available to the trustee or of exercising any trust or power conferred on the trustee. The trustee, however, may refuse to follow any direction that conflicts with law or the indenture or that the trustee determines is unduly prejudicial to the rights of any other holder (it being understood that the trustee does not have an affirmative duty to ascertain whether or not any such directions are unduly prejudicial to such holder) or that would involve the trustee in personal liability. Prior to taking any action under the indenture, the trustee will be entitled to indemnification and/or security satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action. The indenture provides that in the event an Event of Default has occurred and is continuing, the trustee will be required in the exercise of its powers to use the degree of care that a prudent person would use in the conduct of its own affairs.

The indenture provides that if a default with respect to a series occurs and is continuing and is actually known to a responsible officer of the trustee, the trustee must send to each holder of such series notice of the default within 90 days after it occurs. Except in the case of a default in the payment of principal of or interest on any note of a series, the trustee may withhold notice if and so long as it in good faith determines that withholding notice is in the interests of the holders of such series. In addition, we are required to deliver to the trustee, within 120 days after the end of each fiscal year, a certificate indicating whether the signers thereof know of any default that occurred during the previous year.

Modification and Amendment

Subject to certain exceptions, the indenture or the notes may be amended with the consent of the holders of at least a majority in principal amount of the notes of all series under the indenture then outstanding and affected by such amendment, voting as a single class (including consents obtained in connection with a purchase of, or tender offer or exchange offer for, notes). Without the consent of each holder of an outstanding note affected, however, no amendment may, among other things:

(1) make any change to the percentage of principal amount of the notes of such series the holders of which must consent to an amendment;

(2) reduce the principal amount of, premium, or interest on, or extend the stated maturity or interest payment periods, of the notes of such series;

(3) make any note of such series payable in money or securities other than as stated in such note;

(4) impair the right to institute suit for the enforcement of any payment with respect to the notes of such series; or

(5) waive a default in payment of principal of, premium, if any, or interest on the notes of such series or modify any provisions of the indenture relating to modification or amendment thereof.

Without the consent of any holder, we and the trustee may amend the indenture with respect to a series of notes to, among other things:

(1) evidence the succession of another person pursuant to the provisions of the indenture relating to consolidations, mergers, and sales of assets and the assumption by such successor of the covenants, agreements, and obligations in the indenture and in the notes of such series;

(2) surrender any right or power conferred upon us by the indenture, to add to our covenants such further covenants, restrictions, conditions, or provisions for the protection of the holders of the

S-17

TABLE OF CONTENTS

notes of such series as our board of directors will consider to be for the protection of the holders of such series of notes, and to make the occurrence, or the occurrence and continuance, of a default in respect of any of such additional covenants, restrictions, conditions, or provisions a default or an Event of Default under the indenture (provided, however, that with respect to any such additional covenant, restriction, condition, or provision, such supplemental indenture may provide for a period of grace after default, which may be shorter or longer than that allowed in the case of other defaults, may provide for an immediate enforcement upon such default, may limit the remedies available to the trustee upon such default or may limit the right of holders of a majority in aggregate principal amount of the notes of such series to waive such default);

(3) cure any ambiguity or correct or supplement any provision contained in the indenture, in any supplemental indenture or in any note that may be defective or inconsistent with any other provision contained therein;

(4) convey, transfer, assign, mortgage, or pledge any property to or with the trustee, or to make such other provisions in regard to matters or questions arising under the indenture as will not adversely affect in any material respect the interests of any holders of the notes of such series;

(5) modify or amend the indenture in such a manner as to permit or maintain the qualification of the indenture or any supplemental indenture under the Trust Indenture Act as then in effect;

(6) add guarantees with respect to the notes of such series or to secure the notes of such series;

(7) make any change that does not adversely affect the rights of any holder in any material respect;

(8) add to, change, or eliminate any of the provisions of the indenture with respect to the notes of such series, so long as any such addition, change, or elimination not otherwise permitted under the indenture will (a) neither apply to any note created prior to the execution of such supplemental indenture and entitled to the benefit of such provision nor modify the rights of the holders of any such note with respect to such provision, or (b) become effective only when there is no such note outstanding; or

(9) evidence and provide for the acceptance of appointment by a successor or separate trustee with respect to the notes of such series and to add to or change any of the provisions of the indenture as will be necessary to provide for or facilitate the administration of the indenture by more than one trustee.

The consent of the holders is not necessary under the indenture to approve the particular form of any proposed amendment. It is sufficient if such consent approves the substance of the proposed amendment. After an amendment under the indenture becomes effective, we are required to mail to the holders a notice briefly describing such amendment. The failure to give such notice to all the holders, or any defect in the notice, however, will not impair or affect the validity of the amendment. The principal amount of notes of any series issued under the indenture denominated in a currency other than U.S. dollars shall be the U.S. dollar equivalent, as determined by the Company by reference to the noon buying rate in The City of New York for cable transfers for such currency, as such rate is certified for customs purposes by the Federal Reserve Bank of New York on the date of original issuance of such notes, of the principal amount of such notes.

Satisfaction and Discharge of the Indenture

The indenture will generally cease to be of any further effect with respect to the notes of a series if (a) we have delivered to the trustee for cancellation all notes of such series (with certain limited exceptions), or (b) all notes of such series not theretofore delivered to the trustee for cancellation will have become due and payable, or are by their terms to become due and payable within one year or are to be called for redemption within one year, and we will have deposited with the trustee as trust funds the entire amount sufficient to pay at maturity or upon redemption all such notes (and if, in either case, we will also pay or cause to be paid all other sums payable under the indenture by us).

Defeasance

We may terminate at any time all our obligations with respect to the notes of a series and the indenture, which we refer to as “legal defeasance,” except for certain obligations, including those respecting the defeasance

S-18

TABLE OF CONTENTS

trust and obligations to register the transfer or exchange of the notes, to replace mutilated, destroyed, lost, or stolen notes and to maintain a registrar and paying agent in respect of the notes. We may also terminate at any time our obligations with respect to the notes of a series under the covenants described under “— Certain Covenants” and the operation of certain Events of Default, which we refer to as “covenant defeasance.” We may exercise the legal defeasance option notwithstanding our prior exercise of the covenant defeasance option.

If we exercise our legal defeasance option with respect to the notes of a series, payment of the notes of such series may not be accelerated because of an Event of Default with respect thereto. If we exercise the covenant defeasance option with respect to the notes of a series, payment of the notes of such series may not be accelerated because of an event of default specified in clause (3), clause (4), or clause (5) of the definition of “Event of Default.”

The legal defeasance option or the covenant defeasance option with respect to the notes of a series may be exercised only if:

(1)

we irrevocably deposit in trust with the trustee cash or U.S. Government obligations or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized independent registered public accounting firm, to pay the principal of and interest on the outstanding notes of such series to maturity or the applicable redemption date;

(2)

such legal defeasance or covenant defeasance shall not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than the indenture) binding on us;

(3)

no default or Event of Default has occurred and is continuing either (a) on the date of such deposit (other than a default or Event of Default resulting from the borrowing of funds to be applied to such deposit) or (b) insofar as defaults arising out of the bankruptcy provisions are concerned, at any time during the period ending on the 91st day after the date of deposit;

(4)

in the case of the legal defeasance option, we deliver to the trustee an opinion of counsel in the United States reasonably acceptable to the trustee stating that:

we have received from the U.S. Internal Revenue Service (the “IRS”) a letter ruling, or there has been published by the IRS a Revenue Ruling, or

since the date of the indenture, there has been a change in the applicable U.S. federal income tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the beneficial owners of the notes of such series will not recognize income, gain, or loss for U.S. federal income tax purposes as a result of such legal defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such legal defeasance had not occurred;

(5)

in the case of the covenant defeasance option, we deliver to the trustee an opinion of counsel in the United States reasonably acceptable to the trustee to the effect that the beneficial owners of the notes of such series will not recognize income, gain, or loss for U.S. federal income tax purposes as a result of such covenant defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred;

(6)

we deliver to the trustee an opinion of counsel to the effect that on the 91st day after the date of deposit, the trust funds deposited will not be subject to the effect of any applicable bankruptcy, insolvency, reorganization, or similar laws affecting creditors’ rights generally;

S-19

TABLE OF CONTENTS

(7)

we deliver to the trustee an officers’ certificate stating that the deposit was not made with the intent of preferring the holders of the notes of such series over any other of our creditors or with the intent of defeating, hindering, delaying, or defrauding any other of our creditors; and

(8)

we deliver to the trustee an officers’ certificate and an opinion of counsel, each stating that all conditions precedent to the legal defeasance or covenant defeasance have been complied with as required by the indenture.

If we defease our obligations under the indenture, we will be released from our obligations under the provisions described under “— Certain Covenants.”

Reports

So long as any notes of a series are outstanding, we will furnish to the trustee and the holders of the notes of such series, within the time periods (including any extensions thereof) specified in the SEC’s rules and regulations, copies of our annual report and quarterly reports that we are required to file with the SEC pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Documents filed by us with the SEC via the EDGAR system will be deemed to have been furnished to the trustee and the holders of the notes of such series as of the time such documents are filed via EDGAR; provided, however, that the trustee shall have no obligation whatsoever to determine whether or not such information, documents, or reports have been filed via EDGAR.

Global Notes, Book-Entry Form

We have obtained the information in this section concerning Clearstream and Euroclear and their book-entry systems and procedures from sources that we believe to be reliable. We take no responsibility for an accurate portrayal of this information. In addition, the description of the clearing systems in this section reflects our understanding of the rules and procedures of Clearstream and Euroclear as they are currently in effect. Those clearing systems could change their rules and procedures at any time.

The notes will initially be represented by one or more fully registered global notes. Each such global note will be deposited with, or on behalf of, a common depositary, and registered in the name of the nominee of the common depositary for the accounts of Clearstream and Euroclear. Except as set forth below, the global notes may be transferred, in whole and not in part, only to Euroclear or Clearstream or their respective nominees. You may hold your interests in the global notes in Europe through Clearstream or Euroclear, either as a participant in such systems or indirectly through organizations that are participants in such systems. Clearstream and Euroclear will hold interests in the global notes on behalf of their respective participating organizations or customers through customers’ securities accounts in Clearstream’s or Euroclear’s names on the books of their respective depositaries. Book-entry interests in the notes and all transfers relating to the notes will be reflected in the book-entry records of Clearstream and Euroclear.

The distribution of the notes will be cleared through Clearstream and Euroclear. Any secondary market trading of book-entry interests in the notes will take place through Clearstream and Euroclear participants and will settle in same-day funds. Owners of book-entry interests in the notes will receive payments relating to their notes in euro, except as described under “— Issuance in Euro.”

Clearstream and Euroclear have established electronic securities and payment transfer, processing, depositary, and custodial links among themselves and others, either directly or through custodians and depositaries. These links allow the notes to be issued, held, and transferred among the clearing systems without the physical transfer of certificates. Special procedures to facilitate clearance and settlement have been established among these clearing systems to trade securities across borders in the secondary market.

The policies of Clearstream and Euroclear will govern payments, transfers, exchanges, and other matters relating to the investor’s interest in the notes held by them. We have no responsibility for any aspect of the records kept by Clearstream or Euroclear or any of their direct or indirect participants. We also do not supervise these systems in any way.

S-20

TABLE OF CONTENTS

Clearstream and Euroclear and their participants perform these clearance and settlement functions under agreements they have made with one another or with their customers. You should be aware that they are not obligated to perform or continue to perform these procedures and may modify them or discontinue them at any time.

Except as provided below, owners of beneficial interests in the notes will not be entitled to have the notes registered in their names, will not receive or be entitled to receive physical delivery of the notes in definitive form and will not be considered the owners or holders of the notes under the indenture, including for purposes of receiving any reports delivered by us or the trustee pursuant to the indenture. Accordingly, each person owning a beneficial interest in a note must rely on the procedures of the depositary and, if such person is not a participant, on the procedures of the participant through which such person owns its interest, in order to exercise any rights of a holder of notes.

We have been advised by Clearstream and Euroclear, respectively, as follows:

Clearstream

Clearstream advises that it is incorporated under the laws of Luxembourg as a professional depositary. Clearstream holds securities for its participating organizations (“Clearstream Participants”) and facilitates the clearance and settlement of securities transactions between Clearstream Participants through electronic book-entry changes in accounts of Clearstream Participants, thereby eliminating the need for physical movement of certificates. Clearstream provides to Clearstream Participants, among other things, services for safekeeping, administration, clearance and settlement of internationally traded securities and securities lending and borrowing. Clearstream interfaces with domestic markets in several countries. As a professional depositary, Clearstream is subject to regulation by the Luxembourg Commission for the Supervision of the Financial Sector (Commission de Surveillance du Secteur Financier). Clearstream Participants are recognized financial institutions around the world, including underwriters, securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations and may include the underwriters. Indirect access to Clearstream is also available to others, such as banks, brokers, dealers, and trust companies that clear through or maintain a custodial relationship with a Clearstream Participant, either directly or indirectly.

Distributions with respect to interests in the notes held beneficially through Clearstream will be credited to cash accounts of Clearstream Participants in accordance with its rules and procedures.

Euroclear

Euroclear advises that it was created in 1968 to hold securities for participants of Euroclear (“Euroclear Participants”) and to clear and settle transactions between Euroclear Participants through simultaneous electronic book-entry delivery against payment, thereby eliminating the need for physical movement of certificates and any risk from lack of simultaneous transfers of securities and cash. Euroclear includes various other services, including securities lending and borrowing and interfaces with domestic markets in several countries. Euroclear is operated by Euroclear Bank SA/NV (the “Euroclear Operator”). All operations are conducted by the Euroclear Operator, and all Euroclear securities clearance accounts and Euroclear cash accounts are accounts with the Euroclear Operator. Euroclear Participants include banks (including central banks), securities brokers and dealers and other professional financial intermediaries and may include the underwriters. Indirect access to Euroclear is also available to other firms that clear through or maintain a custodial relationship with a Euroclear Participant, either directly or indirectly.

The Terms and Conditions Governing Use of Euroclear and the related Operating Procedures of the Euroclear System, or the Euroclear Terms and Conditions, and applicable Belgian law govern securities clearance accounts and cash accounts with the Euroclear Operator. Specifically, these terms and conditions govern:

•

transfers of securities and cash within Euroclear;

•

withdrawal of securities and cash from Euroclear; and

•

receipt of payments with respect to securities in Euroclear.

S-21

TABLE OF CONTENTS

All securities in Euroclear are held on a fungible basis without attribution of specific certificates to specific securities clearance accounts. The Euroclear Operator acts under the terms and conditions only on behalf of Euroclear Participants and has no record of or relationship with persons holding securities through Euroclear Participants.

Distributions with respect to interests in the notes held beneficially through Euroclear will be credited to the cash accounts of Euroclear Participants in accordance with the Euroclear Terms and Conditions.

Clearance and Settlement Procedures

We understand that investors that hold their notes through Clearstream or Euroclear accounts will follow the settlement procedures that are applicable to conventional eurobonds in registered form. Notes will be credited to the securities custody accounts of Clearstream and Euroclear participants on the business day following the settlement date, for value on the settlement date. They will be credited either free of payment or against payment for value on the settlement date.

We understand that secondary market trading between Clearstream and/or Euroclear participants will occur in the ordinary way following the applicable rules and operating procedures of Clearstream and Euroclear. Secondary market trading will be settled using procedures applicable to conventional eurobonds in registered form.

You should be aware that investors will only be able to make and receive deliveries, payments, and other communications involving the notes through Clearstream and Euroclear on days when those systems are open for business. Those systems may not be open for business on days when banks, brokers, and other institutions are open for business in the United States.

In addition, because of time-zone differences, there may be problems with completing transactions involving Clearstream and Euroclear on the same business day as in the United States. U.S. investors who wish to transfer their interests in the notes, or to make or receive a payment or delivery of the notes, on a particular day, may find that the transactions will not be performed until the next business day in Luxembourg or Brussels, depending on whether Clearstream or Euroclear is used.

Clearstream or Euroclear will credit payments to the cash accounts of Clearstream customers or Euroclear participants, as applicable, in accordance with the relevant system’s rules and procedures, to the extent received by its depositary. Clearstream or the Euroclear Operator, as the case may be, will take any other action permitted to be taken by a holder under the indenture on behalf of a Clearstream customer or Euroclear participant only in accordance with its relevant rules and procedures.

Clearstream and Euroclear have agreed to the foregoing procedures in order to facilitate transfers of the notes among participants of Clearstream and Euroclear. They are under no obligation, however, to perform or continue to perform those procedures, and they may discontinue those procedures at any time.

Information Concerning the Trustee and the Paying Agent

We have appointed U.S. Bank Trust Company, National Association as the trustee under the indenture and as registrar and transfer agent, and we have appointed U.S. Bank Europe DAC, UK Branch as paying agent. The trustee, the paying agent and/or their respective affiliates may provide banking and other services to us in the ordinary course of their business.

Governing Law

The indenture is, and the notes will be, governed by, and construed in accordance with, the laws of the state of New York but without giving effect to applicable principles of conflicts of law to the extent that the application of the laws of another jurisdiction would be required thereby.

Material U.S. Federal Income Tax Considerations

The following is a summary of certain material U.S. federal income tax consequences of the purchase, ownership, and disposition of the notes as of the date of this prospectus supplement. Unless otherwise stated, this summary deals only with notes held as capital assets for U.S. federal income tax purposes by persons who purchase the notes for cash pursuant to this offering at their initial offering price.

As used herein, a “U.S. Holder” means a beneficial owner of the notes that is for U.S. federal income tax purposes any of the following:

•

an individual who is a citizen or resident of the United States;

•

a corporation (or any other entity treated as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States, any state thereof, or the District of Columbia;

•

an estate the income of which is subject to U.S. federal income taxation regardless of its source; or

•

a trust if it (i) is subject to the primary supervision of a court within the United States and one or more U.S. persons have the authority to control all substantial decisions of the trust, or (ii) has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person.

The term “non-U.S. Holder” means a beneficial owner of the notes (other than a partnership or any other entity or arrangement treated as a partnership for U.S. federal income tax purposes) that is not a U.S. Holder.

This summary does not address U.S. federal income tax consequences applicable to you if you are a person subject to special tax treatment under the U.S. federal income tax laws, including, without limitation:

•

a dealer in securities or currencies;

•

a financial institution;

•

a regulated investment company;

•

a real estate investment trust;

TABLE OF CONTENTS

result in U.S. federal income tax consequences different from those summarized below. This summary does not represent a detailed description of the U.S. federal income tax consequences to you in light of your particular circumstances and does not address the U.S. federal gift or estate tax or the effects of any state, local, or non-U.S. tax laws. No ruling from the IRS has been or is expected to be sought with respect to the matters discussed herein. There can be no assurance that the IRS will not take a different position concerning the purchase, ownership, or disposition of the notes or that such position would not be sustained. If the IRS contests a conclusion set forth herein, no assurance can be given that an investor would ultimately prevail in a final determination by a court.

If any entity or arrangement classified as a partnership for U.S. federal income tax purposes holds the notes, the tax treatment of a partner will generally depend upon the status of the partner and the activities of the partnership. If you are a partnership or a partner in a partnership holding the notes, you should consult your own tax advisors.

This summary is for general information only and is not intended to be, nor should it be construed to be, legal or tax advice to any holder or prospective holder of the notes and no opinion or representation with respect to U.S. federal income tax consequences to any holder or prospective holder is made.

If you are considering the purchase of notes, you should consult your own tax advisors concerning the particular U.S. federal income tax consequences to you of the ownership of the notes, as well as the consequences to you arising under any other tax law including the laws of any other taxing jurisdiction.

Classification of the Notes

In certain circumstances, we may be obligated to pay amounts in excess of stated interest or principal on the notes (see “Description of Notes — Optional Redemption,” “Description of Notes — Payment of Additional Amounts,” “Description of Notes — Redemption for Tax Reasons”). Our obligation to pay such excess amounts may implicate the provisions of the U.S. Treasury regulations relating to “contingent payment debt instruments.” Under these regulations, however, one or more contingencies will not cause a debt instrument to be treated as a contingent payment debt instrument if, as of the issue date, such contingencies in the aggregate are considered “remote” or “incidental.” In addition, these provisions do not apply where a debt instrument provides for alternative payment schedules applicable upon the occurrence of one or more contingencies, including an unconditional option held by the issuer or holder, and the timing and amounts of payments that comprise each payment schedule are known as of the issue date, in which case the option will be deemed to be exercised in a manner that maximizes (in the case of an option held by the holder) or minimizes (in the case of an option held by the issuer) the yield on the debt instrument.

We believe and intend to take the position that the contingencies on the notes described above should not cause the contingent payment debt instrument rules of the U.S. Treasury regulations to apply. Our position is binding on a holder, unless the holder discloses in the proper manner to the IRS that it is taking a different position. However, we can give no assurance that our position would be sustained if challenged by the IRS. A successful challenge of this position by the IRS could require a holder subject to U.S. federal income taxation to accrue ordinary income at a rate that is higher than the stated interest rate and to treat any gain recognized on a sale or other taxable disposition of a note as ordinary income, rather than capital gain. The remainder of this disclosure assumes that the notes will not be considered contingent payment debt instruments for U.S. federal income tax purposes. Prospective acquirors are urged to consult their own tax advisors regarding the potential application to the notes of the contingent payment debt instrument U.S. Treasury regulations and the consequences thereof.

Material Tax Consequences to U.S. Holders

The following is a summary of material U.S. federal income tax consequences that will apply to U.S. Holders of the notes.

Payments of Stated Interest. Stated interest on a note generally will be taxable to you as ordinary income at the time it is paid or accrued in accordance with your method of accounting for U.S. federal income tax purposes and will be treated as U.S. source income.

S-27

TABLE OF CONTENTS

If you use the cash basis method of accounting for U.S. federal income tax purposes, you will be required to include in income the U.S. dollar value of the stated interest received, determined by translating euros received at the spot rate of exchange on the date such payment is received regardless of whether the payment is in fact converted into U.S. dollars. You will not recognize exchange gain or loss with respect to the receipt of such payment of stated interest, but may recognize exchange gain or loss attributable to the actual disposition of the euros so received, as described below under “— Exchange Gain or Loss.”

If you use the accrual method of accounting for U.S. federal income tax purposes, you will be required to include in income (as ordinary income) the U.S. dollar value of the stated interest that has accrued with respect to your notes during an accrual period. The U.S. dollar value of such euro denominated accrued interest may be determined in accordance with either of two methods. Under the first method, you will be required to translate such stated interest at the average rate of exchange for the period or periods during which such stated interest accrued or, in the case of an accrual period that spans two taxable years of a U.S. Holder, the part of the period within the taxable year. Under the second method, you may elect to translate stated interest income at the spot rate of exchange on:

•

the last day of the accrual period (or the date the stated interest payment is received if such date is within five business days of the last day of the accrual period), or

•

the last day of the taxable year, if the accrual period straddles your taxable year, for the portion of the accrual period ending on the last day of such taxable year.

This election will apply to all debt obligations you hold from year to year and cannot be changed without the consent of the IRS. You should consult your own tax advisor as to the advisability of making the above election.

In addition, if you use the accrual method of accounting for U.S. federal income tax purposes, upon receipt of a stated interest payment on a note (including amounts received upon the sale or other taxable disposition of a note attributable to accrued interest previously included in income), you will recognize ordinary income or loss (and not interest income and expense) in an amount equal to the difference, if any, between the U.S. dollar value of such payment (determined by translating the euros received at the spot rate of exchange on the date such payment is received) and the U.S. dollar value of the stated interest income you previously included in income with respect to such payment, regardless of whether the payment is actually converted into U.S. dollars.

Sale, Exchange, Redemption, Retirement, or Other Taxable Disposition of Notes. Upon the sale, exchange, redemption, retirement, or other taxable disposition of a note, you generally will recognize gain or loss equal to the difference between the amount realized upon the sale, exchange, redemption, retirement, or other taxable disposition (less an amount equal to any accrued but unpaid stated interest, which will be treated as interest income to the extent not previously included in income) and your adjusted tax basis in the note. Your adjusted tax basis in a note generally will be your U.S. dollar cost for that note. If you purchased your note with euros, your cost generally will be the U.S. dollar value of the euros paid for such note determined at the spot rate on the date of such purchase of such note. If your note is sold, exchanged, redeemed, retired, or otherwise disposed of in a taxable transaction for euros, the amount realized generally will be the U.S. dollar value of the euros received on the date of sale, exchange, redemption, retirement, or other taxable disposition. If you are a cash method taxpayer and the notes are traded on an established securities market, euros paid or received will be translated into U.S. dollars at the spot rate on the settlement date of the sale, exchange, redemption, retirement, or other taxable disposition. An accrual basis U.S. Holder may elect the same treatment with respect to the purchase or disposition of the notes traded on an established securities market, provided that the election is applied consistently to all debt instruments from year to year. Such election cannot be changed without the consent of the IRS. An accrual basis U.S. Holder that does not make such election will recognize exchange gain or loss to the extent that there are exchange rate fluctuations between the disposition date and the settlement date, as discussed below under “— Exchange Gain or Loss.” You should consult your tax advisor regarding the foreign currency tax consequences of a disposition (including whether the U.S. dollar value of the amount realized should be determined on the trade date or the settlement date).

Subject to the foreign currency rules discussed below, your gain or loss will generally be capital gain or loss and will be long term capital gain or loss if at the time of sale, exchange, redemption, retirement, or

S-28

TABLE OF CONTENTS

other taxable disposition, you have held the note for more than one year. Capital gains of non-corporate U.S. Holders, including individuals, derived with respect to capital assets held for more than one year are eligible for reduced rates of taxation. The deductibility of capital losses is subject to limitations. Gain or loss realized by you on the sale, exchange, redemption, retirement, or other taxable disposition of a note generally will be treated as U.S. source gain or loss.

Exchange Gain or Loss. Gain or loss recognized upon the sale, exchange, redemption, retirement, or other taxable disposition of a note that is attributable to changes in currency exchange rates relating to the principal amount of such note will be treated as exchange gain or loss. Exchange gain or loss will be treated as ordinary income or loss and generally will be U.S. source gain or loss. For these purposes, the principal amount of the note is your purchase price for the note calculated in euros on the date of purchase, and the amount of exchange gain or loss recognized is equal to the difference between (i) the U.S. dollar value of the principal amount determined on the date of the sale, exchange, redemption, retirement, or other taxable disposition of the note (or on the settlement date, if applicable, in the case of cash basis or electing accrual basis U.S. Holders, provided the note is traded on an established securities market), and (ii) the U.S. dollar value of the principal amount determined on the date you purchased the note (or on the settlement date, if applicable, in the case of cash basis or electing accrual basis U.S. Holders, provided the note is traded on an established securities market). The amount of exchange gain or loss (with respect to both principal and accrued and unpaid stated interest) will be limited to the amount of overall gain or loss realized on the disposition of the note.

Upon the sale, exchange, retirement, or other taxable disposition of a note, if the notes are traded on an established securities market, a cash basis U.S. Holder (or, upon election, an accrual basis U.S. Holder) will have a basis in the euro received equal to the U.S. dollar value thereof at the spot rate of exchange in effect on the settlement date of such sale, exchange, retirement, or disposition (that is, the same date that the euro are valued for purposes of determining the amount realized on the note) and will not generate any additional exchange gain or loss. In all other cases, since the amount realized is based on the spot rate of exchange in effect on the date of the sale, exchange, retirement, or other taxable disposition of the note (including the trade date if the notes are traded on an established securities market), (i) the taxpayer will realize foreign exchange gain or loss to the extent the U.S. dollar value of the euro received (based on the spot rate of exchange in effect on the date of the actual receipt) differs from the U.S. dollar value of the euro on the date of the sale, exchange, retirement, or other taxable disposition of the note, and (ii) the taxpayer’s basis in the euro received will equal the U.S. dollar value of the euro, based on the spot rate of exchange in effect on the date of receipt.

Any gain or loss recognized by you on a sale, exchange, redemption, retirement, or other taxable disposition of the euros will be ordinary income or loss and generally will be U.S. source gain or loss.

Additional Tax on Net Investment Income. The “net investment income” (or undistributed “net investment income,” in the case of a trust or estate) of certain U.S. Holders that are individuals, trusts, or estates and that have modified adjusted gross income (or adjusted gross income, in the case of a trust or estate) above a certain threshold (which in the case of an individual is between $125,000 and $250,000, depending on the individual’s circumstances) is subject to a 3.8% tax, in addition to otherwise applicable U.S. federal income tax. “Net investment income” generally includes, among other things, interest income on and capital gain from the disposition of securities like the notes, subject to certain exceptions. If you are a U.S. Holder that is an individual, estate, or trust, you are urged to consult your own tax advisor regarding the applicability of this tax to your investment in the notes.

Reportable Transactions. U.S. Treasury regulations meant to require the reporting of certain tax shelter transactions could be interpreted to cover transactions generally not regarded as tax shelters, including certain foreign currency transactions. Under the U.S. Treasury regulations, certain transactions are required to be reported to the IRS including, in certain circumstances, a sale, exchange, redemption, retirement, or other taxable disposition of a foreign currency note, or foreign currency received in respect of a foreign currency note to the extent that such sale, exchange, redemption, retirement, or other taxable disposition results in a tax loss in excess of a threshold amount. Prospective investors considering the purchase of the notes should consult with their own tax advisor to determine the tax return obligations, if any, with respect to an investment in the notes, including any requirement to file IRS Form 8886 (Reportable Transaction Disclosure Statement).

TABLE OF CONTENTS

Material Tax Consequences to Non-U.S. Holders

The following is a summary of the material U.S. federal income tax consequences that will apply to non-U.S. Holders of the notes.

U.S. Federal Withholding Tax. Subject to the discussion below regarding effectively connected income, FATCA, and backup withholding, interest paid on a note to a non-U.S. Holder generally will not be subject to U.S. federal income or withholding tax under the “portfolio interest” exemption, provided that:

•

such interest is not effectively connected with your conduct of a trade or business in the United States;

•

you do not directly or indirectly (actually or constructively) own 10% or more of the total combined voting power of all classes of our voting stock within the meaning of the Code and applicable U.S. Treasury regulations;

•

you are not a controlled foreign corporation that is related to us through stock ownership;

•

you are not a bank whose receipt of interest on the notes is described in Section 881(c)(3)(A) of the Code; and

•

either (a) you provide your name and address on an applicable IRS Form W-8 and certify, under penalties of perjury, that you are not a U.S. person, or (b) you hold your notes through certain foreign intermediaries and satisfy the certification requirements of applicable U.S. Treasury regulations. Special certification rules apply to non-U.S. Holders that are pass-through entities rather than corporations or individuals.

If you cannot satisfy the requirements described above, payments of interest made to you will be subject to a 30% U.S. federal withholding tax, unless you provide the applicable withholding agent with a properly executed:

•

IRS Form W-8BEN or W-8BEN-E (or other applicable form) certifying an exemption from or reduction in withholding under the benefit of an applicable income tax treaty; or

•

IRS Form W-8ECI (or other applicable form) certifying interest paid on the notes is not subject to withholding tax because it is effectively connected with your conduct of a trade or business in the United States (as discussed below under “— U.S. Federal Income Tax”).

The 30% U.S. federal withholding tax generally will not apply to any payment of principal or gain that you realize on the sale, exchange, redemption, retirement, or other disposition of a note.

U.S. Federal Income Tax. If you are engaged in a trade or business in the United States and interest on the notes is effectively connected with the conduct of that trade or business (and, if required by an applicable income tax treaty, is attributable to a U.S. permanent establishment or fixed base), then you will be subject to U.S. federal income tax on that interest on a net income basis (although you will be exempt from the 30% U.S. federal withholding tax, provided the certification requirements discussed above in “— U.S. Federal Withholding Tax” are satisfied) in generally the same manner as if you were a U.S. person. In addition, if you are a foreign corporation, you may be subject to a branch profits tax equal to 30% (or lower applicable income tax treaty rate) of your effectively connected earnings and profits, subject to adjustments.

Subject to the discussion below regarding FATCA and backup withholding, any gain realized on the disposition of a note (excluding any amount allocable to accrued but unpaid interest) generally will not be subject to U.S. federal income tax unless:

•

the gain is effectively connected with your conduct of a trade or business in the United States (and, if required by an applicable income tax treaty, is attributable to a U.S. permanent establishment or fixed base); or

•

you are an individual who is present in the United States for 183 days or more in the taxable year of that disposition, and certain other conditions are met.

Proceeds from a disposition of a note that are accrued but unpaid interest generally will be subject to, or exempt from, tax to the same extent as described above with respect to interest paid on a note.

S-30

TABLE OF CONTENTS

Information Reporting and Backup Withholding

U.S. Holders. In general, information reporting requirements will apply to certain payments of interest and principal paid on the notes and to the proceeds of the sale or other disposition (including a redemption) of a note paid to you (unless you are an exempt recipient). Backup withholding may apply to such payments if you fail to provide a correct taxpayer identification number or a certification that you are not subject to backup withholding.

Backup withholding is not an additional tax and any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against your U.S. federal income tax liability provided the required information is timely furnished to the IRS.

Non-U.S. Holders. Generally, the amount of interest paid to you and the amount of tax, if any, withheld with respect to those payments will be reported to the IRS. Copies of the information returns reporting such interest payments and any withholding may also be made available to the tax authorities in the country in which you reside under the provisions of an applicable tax treaty.

In general, you will not be subject to backup withholding with respect to payments of interest on the notes that we make to you provided that the applicable withholding agent does not have actual knowledge or reason to know that you are a U.S. person, and such withholding agent has received from you the required certification that you are not a U.S. person as described above in the fifth bullet point under “Material Tax Consequences to Non-U.S. Holders — U.S. Federal Withholding Tax.”

Information reporting and, depending on the circumstances, backup withholding will apply to the proceeds of a sale or other disposition of notes within the United States or conducted through certain U.S.-related financial intermediaries, unless you certify to the payor under penalties of perjury that you are not a U.S. person (and the payor does not have actual knowledge or reason to know that you are a U.S. person), or you otherwise establish an exemption.

FATCA Withholding

Under Sections 1471 through 1474 of the Code (such Sections commonly referred to as “FATCA”), a 30% U.S. federal withholding tax may apply to any interest income paid on the notes paid to (i) a “foreign financial institution” (as specifically defined in the Code) that does not provide sufficient documentation, typically on IRS Form W-8BEN-E, evidencing either (x) an exemption from FATCA, or (y) its compliance (or deemed compliance) with FATCA (which may alternatively be in the form of compliance with an intergovernmental agreement with the United States) in a manner that avoids withholding, or (ii) a “non-financial foreign entity” (as specifically defined in the Code) that does not provide sufficient documentation, typically on IRS Form W-8BEN-E, evidencing either (x) an exemption from FATCA, or (y) adequate information regarding the “substantial United States owners” (as specifically defined in the Code) of such entity (if any). If an interest payment is both subject to withholding under FATCA and subject to the withholding tax discussed above under “Material Tax Consequences to Non-U.S. Holders — U.S. Federal Withholding Tax,” the withholding under FATCA may be credited against, and therefore reduce, such other withholding tax. If you are a foreign financial entity or a non-financial foreign entity in a jurisdiction that has entered into an intergovernmental agreement with the United States, you may be subject to different rules. You should consult your own tax advisor regarding these rules and whether they may be relevant to your ownership and disposition of notes.

Standard Chartered Bank will not effect any offers or sales of any notes in the United States unless it is through one or more U.S. registered broker-dealers as permitted by the regulations of the Financial Industry Regulation Authority.

ICBC Standard Bank Plc is restricted in its U.S. securities dealings under the United States Bank Holding Company Act and may not underwrite, subscribe, agree to purchase or procure purchasers to purchase notes that are offered or sold in the United States. Accordingly, ICBC Standard Bank Plc shall not be obligated to, and shall not, underwrite, subscribe, agree to purchase or procure purchasers to purchase notes that may be offered or sold by other underwriters in the United States. ICBC Standard Bank Plc shall offer and sell the notes constituting part of its allotment solely outside the United States.

The underwriting agreement provides that the underwriters’ obligations to purchase the notes depend on the satisfaction of the conditions contained in the underwriting agreement, and that if any notes of a series are purchased by the underwriters, all of the notes of such series must be purchased. The offering of the notes by the underwriters is subject to receipt and acceptance and subject to the underwriters’ right to reject any order in whole or in part. The conditions contained in the underwriting agreement include the condition that all the representations and warranties made by us to the underwriters are true, that there has been no material adverse change in our condition or that of the financial markets, and that we deliver to the underwriters customary closing documents.

The following table shows the underwriting discounts to be paid to the underwriters by us in connection with this offering.

dealers at such price less a concession not in excess of % of the principal amount of the 20 Notes and % of the principal amount of the 20 Notes.

The underwriters may allow, and such dealers may reallow, a concession not in excess of % of the principal amount of the 20 Notes and % of the principal amount of the 20 Notes to certain other dealers. If all the notes are not sold at the initial offering price, the underwriters may change the offering price and the other selling terms.

The expenses of the offering, not including the underwriting discounts, are estimated to be approximately € and are payable by us.

Each series of the notes will constitute a new issue of securities with no established trading market. We intend to file an application to list each series of notes on Nasdaq. If the application is approved, trading of the notes on Nasdaq is expected to begin within 30 days after the original issue date of the notes. The underwriters have advised us that they intend to make a market in the notes prior to commencement of any trading on Nasdaq. However, the underwriters will have no obligation to do so, and a market for the notes may not develop prior to commencement of trading on Nasdaq or, if developed, may not be maintained.

In connection with the offering, one or more of the underwriters may engage in transactions that stabilize, maintain, or otherwise affect the market price of the notes during and after the offering. Specifically, such persons may over-allot or create a short position in the notes for their own account by selling more notes than have been sold to them by the Company. Such persons may also elect to cover any such short position by purchasing notes in the open market. In addition, such persons may stabilize or maintain the price of the notes by bidding for or purchasing notes in the open market and may impose penalty bids, under which selling concessions allowed to syndicate members or other broker-dealers participating in the offering of the notes are reclaimed if notes previously distributed in the offering are repurchased in connection with stabilization transactions or otherwise. The effect of these transactions may be to stabilize or maintain the market price of the notes at a level above that which might otherwise prevail in the open market. The imposition of a penalty bid may also affect the price of the notes to the extent that it discourages resales thereof. No representation is made as to the magnitude or effect of any such stabilizing or other transactions. Such transactions, if commenced, may be discontinued at any time.

We have agreed to indemnify the underwriters against, or to contribute to payments that the underwriters may be required to make in respect of, certain liabilities, including liabilities under the Securities Act of 1933, as amended.

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing, and brokerage activities. Certain of the underwriters and their respective affiliates have, from time to time, performed, and may in the future perform, various financial advisory, commercial banking, and investment banking services for the issuer, for which they received or will receive customary fees and expenses.

Certain of the underwriters or their affiliates are agents and/or lenders under our credit facility and may hold some of our outstanding senior notes. As a result, to the extent we use any of the net proceeds from this offering to repay outstanding amounts thereunder, certain of the underwriters and/or their affiliates may receive a portion of the net proceeds from this offering. U.S. Bancorp Investments, Inc., one of the underwriters, is also an affiliate of the trustee, registrar and transfer agent.

In the ordinary course of their various business activities, the underwriters and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers, and such investment and securities activities may involve securities and/or instruments of the issuer. Certain of the underwriters and their affiliates that have a lending relationship with us routinely hedge, and certain other of those underwriters or affiliates thereof may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, such underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including

S-33

TABLE OF CONTENTS

potentially the notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the notes offered hereby. The underwriters and their respective affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

We expect that the notes will be delivered against payment therefor on or about , 2025, which will be the business day following the date of pricing of the notes (this settlement cycle being referred to as “T+ ”). Under Rule 15c6-1 of the Exchange Act, trades in the secondary market generally are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes prior to the first business day before delivery of the notes hereunder will be required, by virtue of the fact that the notes will initially settle in T+ , to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of the notes who wish to trade the notes prior to the first business day before the date of delivery should consult their own advisors.

Sales Outside the United States

The notes may be offered and sold in the United States and certain jurisdictions outside the United States in which such offer and sale is permitted.

Each underwriter has represented and agreed that it has not offered, sold or delivered and it will not offer, sell, or deliver, directly or indirectly, any of the notes or distribute this prospectus supplement, the accompanying prospectus or any other offering material relating to the notes, in or from any jurisdiction except under circumstances that will, to the best of its knowledge and belief, result in compliance with the applicable laws and regulations thereof and that will not impose any obligations on us except as agreed to with us in advance of such offer, sale, or delivery.

Prohibition of sales to EEA Retail Investors

Each underwriter has represented and agreed that it has not offered, sold or otherwise made available and will not offer, sell, or otherwise make available any notes to any retail investor in the European Economic Area. For the purposes of this provision, the expression “retail investor” means a person who is one (or more) of the following:

•

ABOUT THIS PROSPECTUS

This prospectus is part of an automatic registration statement on Form S-3 that we filed with the SEC using the “shelf” registration process under the Securities Act of 1933, as amended (the “Securities Act”). Under the shelf registration process, we may from time to time sell the securities described in this prospectus in one or more offerings.

This prospectus provides you with a general description of the securities that we may offer. Each time we sell securities in a manner not described herein, we will provide you with a prospectus supplement containing specific information about the terms of the offering and the means of distribution of the securities. The prospectus supplement may also add, update, or change information contained in this prospectus and may include other special considerations applicable to such offering of securities. If there is any inconsistency between the information in this prospectus and any prospectus supplement, you should rely on the information in the prospectus supplement. You should read carefully this prospectus and any prospectus supplement together with the additional information described under the heading “Where You Can Find More Information.”

The prospectus supplement will describe: the terms of the securities offered, any initial public offering price, the price paid to us for securities, the net proceeds to us, the manner of distribution and any underwriting compensation, and any other material terms related to the offering of the applicable securities. For more detail on the terms of the securities, you should read the exhibits filed with or incorporated by reference in our registration statement of which this prospectus forms a part.

In this prospectus, unless the context otherwise requires, the terms “Booking Holdings,” “we,” “our,” “us” and the “Company” refer to Booking Holdings Inc., a Delaware corporation whose shares of common stock are listed on The Nasdaq Global Select Market under the symbol “BKNG,” and its subsidiaries.

References to “securities” include any security that we might sell under this prospectus or any prospectus supplement.

We prepare our financial statements in U.S. dollars and prepare our financial statements, including all of the financial statements incorporated by reference in this prospectus, in conformity with accounting principles generally accepted in the United States, or “U.S. GAAP.” Our fiscal year ends on December 31. In this prospectus, except where otherwise indicated, references to “$” or “dollars” are to the lawful currency of the United States.

This prospectus contains summaries of certain provisions contained in some of the documents described herein. Please refer to the actual documents for complete information. All of the summaries are qualified in their entirety by the actual documents. Copies of the documents referred to herein have been filed, or will be filed or incorporated by reference, as exhibits to the registration statement of which this prospectus is a part, and you may obtain copies of those documents as described below under “Where You Can Find More Information.”

Pursuant to this registration statement, we may offer, issue, and sell securities as set forth on the cover page of this prospectus. Because we are a “well-known seasoned issuer,” as defined in Rule 405 of the Securities Act, we may add to and offer additional securities by filing a prospectus supplement with the SEC at the time of the offer. In addition, we are able to add our subsidiaries and securities to be issued by them if we guarantee such securities.

We are only responsible for the information contained in or incorporated by reference in this prospectus, any accompanying prospectus supplement, or any free writing prospectus. We have not authorized anyone to provide you with different information. The distribution of this prospectus and sale of these securities in certain jurisdictions may be restricted by law.

will have become due and payable will be repaid to us, and the holders of those debt securities or any related coupons will thereafter look only to us for payment thereof.

Global Securities

The debt securities of a series may be issued in whole or in part in the form of one or more global securities. A global security is a debt security that represents, and is denominated in an amount equal to the aggregate principal amount of, all outstanding debt securities of a series, or any portion thereof, in either case having the same terms, including the same original issue date, date or dates on which principal and interest are due, and interest rate or method of determining interest. A global security will be deposited with, or on behalf of, a depositary, which will be identified in the prospectus supplement relating to such debt securities. Global securities may be issued in either registered or bearer form and in either temporary or definitive form. Unless and until it is exchanged in whole or in part for the individual debt securities represented thereby, a global security may not be transferred except as a whole by the depositary to a nominee of the depositary, by a nominee of the depositary to the depositary or another nominee of the depositary, or by the depositary or any nominee of the depositary to a successor depositary or any nominee of such successor.

The terms of the depositary arrangement with respect to a series of debt securities will be described in the prospectus supplement relating to such debt securities. We anticipate that the following provisions will generally apply to depositary arrangements, in all cases subject to any restrictions or limitations described in the prospectus supplement relating to such debt securities.

Upon the issuance of a global security, the depositary for such global security will credit, on its book entry registration and transfer system, the respective principal amounts of the individual debt securities represented by such global security to the accounts of persons that have accounts with the depositary (“participants”). Such accounts will be designated by the dealers or underwriters with respect to such debt securities or, if such debt securities are offered and sold directly by us or through one or more agents, by us or such agents. Ownership of beneficial interests in a global security will be limited to participants or persons that hold beneficial interests through participants. Ownership of beneficial interests in such global security will be shown on, and the transfer of that ownership will be effected only through, records maintained by the depositary (with respect to interests of participants) or records maintained by participants (with respect to interests of persons other than participants). The laws of some states require that certain purchasers of securities take physical delivery of such securities in definitive form. Such limitations and laws may impair the ability to transfer beneficial interests in a global security.

So long as the depositary for a global security, or its nominee, is the registered owner or holder of such global security, such depositary or nominee, as the case may be, will be considered the sole owner or holder of the individual debt securities represented by such global security for all purposes under the indenture. Except as provided below, owners of beneficial interests in a global security will not be entitled to have any of the individual debt securities represented by such global security registered in their names, will not receive or be entitled to receive physical delivery of any of such debt securities in definitive form, and will not be considered the owners or holders thereof under the indenture.

Payments of principal, premium, and interest with respect to individual debt securities represented by a global security will be made to the depositary or its nominee, as the case may be, as the registered owner or holder of such global security. Neither we, the trustee, any paying agent, or registrar for such debt securities nor any agent of ours or the trustee will have any responsibility or liability for:

•

any aspect of the records relating to or payments made by the depositary, its nominee or any participants on account of beneficial interests in the global security or for maintaining, supervising or reviewing any records relating to such beneficial interests;

•

the payment to the owners of beneficial interests in the global security of amounts paid to the depositary or its nominee; or

•

any other matter relating to the actions and practices of the depositary, its nominee or its participants.

Neither we, the trustee, any paying agent, or registrar for such debt securities or any agent of ours or the trustee will be liable for any delay by the depositary, its nominee or any of its participants in identifying the

TABLE OF CONTENTS

owners of beneficial interests in the global security, and we and the trustee may conclusively rely on, and will be protected in relying on, instructions from the depositary or its nominee for all purposes.

We expect that the depositary for a series of debt securities or its nominee, upon receipt of any payment of principal, premium, or interest with respect to a definitive global security representing any of such debt securities, will immediately credit participants’ accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of such global security, as shown on the records of the depositary or its nominee. We also expect that payments by participants to owners of beneficial interests in such global security held through such participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers and registered in “street name.” Such payments will be the responsibility of such participants. Receipt by owners of beneficial interests in a temporary global security of payments of principal, premium, or interest with respect thereto will be subject to the restrictions described in an applicable prospectus supplement. See “Limitations on Issuance of Securities in Bearer Form” below.

If the depositary for a series of debt securities is at any time unwilling, unable, or ineligible to continue as depositary, we will appoint a successor depositary. If a successor depositary is not appointed by us within 90 days, we will issue individual debt securities of such series in exchange for the global security representing such series of debt securities. The global security of a series shall also be exchangeable for individual debt securities of such series if an event of default with respect to such series of debt securities shall have happened and be continuing. In addition, we may at any time and in our sole discretion determine to no longer have debt securities of a series represented by a global security and, in such event, will issue individual debt securities of such series in exchange for the global security representing such series of debt securities. Furthermore, if we so specify with respect to the debt securities of a series, an owner of a beneficial interest in a global security representing debt securities of such series may, on terms acceptable to us, the trustee, and the depositary for such global security, receive individual debt securities of such series in exchange for such beneficial interests. In any such instance, an owner of a beneficial interest in a global security will be entitled to physical delivery of individual debt securities of the series represented by such global security equal in principal amount to such beneficial interest and to have such debt securities registered in its name (if the debt securities are issuable as securities in registered form). Individual debt securities of such series so issued generally will be issued:

•

as securities in registered form in denominations, unless otherwise specified by us, of $1,000 and integral multiples thereof if the debt securities are issuable as securities in registered form;

•

as securities in bearer form in the denomination or denominations specified by us if the debt securities are issuable as securities in bearer form; or

•

as either securities in registered form or securities in bearer form as described above if the debt securities are issuable in either form.

Limitations on Issuance of Securities in Bearer Form

The debt securities of a series may be issued as securities in registered form (which will be registered as to principal and interest in the register maintained by the registrar for such debt securities) or securities in bearer form (which will be transferable only by delivery). If such debt securities are issuable as securities in bearer form, the applicable prospectus supplement will describe certain special limitations and considerations that will apply to such debt securities.

Certain Covenants

If debt securities are issued, the indenture, as supplemented for a particular series of debt securities, will contain certain covenants for the benefit of the holders of such series of debt securities, which will be applicable (unless waived or amended) so long as any of the debt securities of such series are outstanding, unless stated otherwise in the prospectus supplement. The specific terms of the covenants, and summaries thereof, will be set forth in the prospectus supplement relating to such series of debt securities.

Subordination

Debt securities of a series, and any guarantees, may be subordinated (“subordinated debt securities”) to senior indebtedness (as defined in the applicable prospectus supplement) to the extent set forth in the

TABLE OF CONTENTS

prospectus supplement relating thereto. To the extent we conduct operations through subsidiaries, the holders of debt securities (whether or not subordinated debt securities) will be structurally subordinated to the creditors of our subsidiaries, except to the extent such subsidiary is a guarantor of such series of debt securities.

Events of Default

Each of the following will constitute an event of default under the indenture with respect to any series of debt securities:

•

default in payment of the principal or premium, if any, on the debt securities of that series, when such amount becomes due and payable at maturity, upon acceleration, required redemption, or otherwise;

•

failure to pay interest on the debt securities of that series when such interest becomes due and payable, and such failure continues for a period of 30 days;

•

failure to comply with the obligations described under “— Merger and Consolidation” below;

•

failure to comply for 60 days after notice with any of our other covenants or agreements in the debt securities of that series or the indenture or supplemental indenture related to that series of debt securities; or

•

certain events of bankruptcy, insolvency, or reorganization affecting us.

A prospectus supplement may omit, modify, or add to the foregoing events of default.

A default described under the fourth bullet above will not constitute an event of default until the trustee or the holders of at least 25% in principal amount of the outstanding debt securities notify us of the default and we do not cure such default within the time specified after receipt of such notice.

If any event of default (other than an event of default relating to certain events of bankruptcy, insolvency or reorganization) occurs and is continuing with respect to a particular series of debt securities, either the trustee or the holders of at least 25% in aggregate principal amount of the debt securities of that series then outstanding by written notice to us (and to the trustee if such notice is given by the holders), may declare the principal amount of (or in the case of original issue discount debt securities, the portion thereby specified in the terms thereof), premium, if any, and accrued interest on the debt securities of that series to be immediately due and payable. In the case of certain events of bankruptcy, insolvency or reorganization, the principal amount of, premium, if any, and accrued interest on the debt securities of that series will automatically become and be immediately due and payable without any declaration or other act on the part of the trustee or any holders.

The holders of a majority in aggregate principal amount of the debt securities of any series then outstanding by notice to the trustee under the indenture may on behalf of the holders of all of such series of debt securities waive any existing default or event of default and its consequences under the indenture except a continuing default or event of default in the payment of interest on, or the principal of, the debt securities of such series.

Subject to the provisions of the indenture relating to the duties of the trustee in case an event of default will occur and be continuing, the trustee is under no obligation to exercise any of its rights or powers under the indenture or debt securities at the request or direction of any of the holders of any series of debt securities, unless such holders have offered to the trustee indemnity and/or security satisfactory to it against any loss, liability, or expense. Subject to such provisions for the indemnification of the trustee, the holders of at least a majority in aggregate principal amount of the outstanding debt securities of a series have the right to direct the time, method, and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee with respect to such series of debt securities. The trustee, however, may refuse to follow any direction that conflicts with law or the indenture or that the trustee determines is unduly prejudicial to the rights of any other holder of such series of debt securities (it being understood that the trustee does not have an affirmative duty to ascertain whether or not any such directions are unduly prejudicial to such holders) or that would involve the trustee in personal

TABLE OF CONTENTS

liability. Prior to taking any action under the indenture, the trustee is entitled to indemnification and/or security satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action.

Except to enforce the right to receive payment of principal, premium, if any, or interest when due, no holder of debt securities of a series has any right to institute any proceeding with respect to the indenture or debt securities of such series, or for the appointment of a receiver or a trustee, or for any other remedy thereunder, unless:

•

such holder has previously given to the trustee written notice of a continuing event of default with respect to such series of debt securities;

•

the holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series have made a written request, and such holder or holders have offered reasonable security and/or indemnity against any loss, liability or expense, to the trustee to institute such proceeding as trustee; and

•

the trustee has failed to institute such proceeding, and has not received from the holders of a majority in aggregate principal amount of the outstanding debt securities of that series a direction inconsistent with such request, within 60 days after such notice, request, and offer.

The indenture provides that if a default with respect to a series of debt securities occurs and is continuing and is known to the trustee, the trustee must mail to each holder of such debt securities notice of the default within 90 days after it occurs. Except in the case of a default in the payment of the principal, premium, if any, or accrued and unpaid interest with respect to any debt security of a series, the trustee may withhold notice if and so long as the trustee in good faith determines that withholding notice is in the interests of the holders.

The indenture requires us to furnish to the trustee, within 120 days after the end of each fiscal year, a statement by certain of our officers as to whether or not we, to their knowledge, are in default in the performance or observance of any of the terms, provisions and conditions of the indenture and, if so, specifying all such known defaults.

Street name and other indirect holders should consult their banks and brokers for information on their requirements for giving notice or taking other actions upon a default.

Modification and Waiver

Subject to certain exceptions, the indenture or the debt securities may be amended with the consent of the holders of at least a majority in principal amount of the debt securities of all series under the indenture then outstanding and affected by such amendment, voting as a single class (including consents obtained in connection with a purchase of, or tender offer or exchange offer for, debt securities). Without the consent of each holder of an outstanding debt security affected, however, no amendment may, among other things:

•

make any change to the percentage of principal amount of debt securities of any series the holders of which must consent to an amendment;

•

reduce the principal amount of, premium, if any, or interest on, or extend the stated maturity or interest payment periods of, any debt security;

•

make any debt security payable in money or securities other than that stated in such debt security;

•

make any change that adversely affects such holder’s right to require us to purchase a debt security, if any;

•

impair the right to institute suit for the enforcement of any payment with respect to the debt securities;

•

in the case of any subordinated debt security or coupons pertaining thereto, make any change in the provisions of the indenture relating to subordination that adversely affects the rights of any holder under such provisions; or

TABLE OF CONTENTS

•

waive a default in payment of principal of, premium, if any, or interest on the debt securities of a series or modify any provisions of the indenture relating to modification or amendment thereof.

Without the consent of any holder, we and the trustee may amend the indenture for one or more of the following purposes:

•

to evidence the succession of another person pursuant to the provisions of the indenture relating to consolidations, mergers, and sales of all or substantially all of our assets and the assumption by such successor of the covenants, agreements, and obligations in the indenture and in the debt securities;

•

to surrender any right or power conferred upon us by the indenture, to add to our covenants such further covenants, restrictions, conditions, or provisions for the protection of the holders of all or any series of debt securities as our board of directors will consider to be for the protection of the holders of such debt securities, and to make the occurrence, or the occurrence and continuance, of a default in respect of any of such additional covenants, restrictions, conditions, or provisions a default or an event of default under the indenture (provided, however, that with respect to any such additional covenant, restriction, condition, or provision, such amendment may provide for a period of grace after default, which may be shorter or longer than that allowed in the case of other defaults, may provide for an immediate enforcement upon such default, may limit the remedies available to the trustee upon such default or may limit the right of holders of a majority in aggregate principal amount of any series of debt securities to waive such default);

•

to cure any ambiguity or correct or supplement any provision contained in the indenture, in any supplemental indenture or in any debt securities that may be defective or inconsistent with any other provision contained therein;

•

to convey, transfer, assign, mortgage, or pledge any property to or with the trustee, or to make such other provisions in regard to matters or questions arising under the indenture as will not adversely affect in any material respect the interests of any holders of debt securities of any series;

•

to modify or amend the indenture in such a manner as to permit or maintain the qualification of the indenture or any supplemental indenture under the Trust Indenture Act as then in effect;

•

to add to or change any of the provisions of the indenture to provide that securities in bearer form may be registerable as to principal, to change or eliminate any restrictions on the payment of principal or premium with respect to securities in registered form or of principal, premium, or interest with respect to securities in bearer form, or to permit securities in registered form to be exchanged for securities in bearer form, so as to not adversely affect the interests of the holders of debt securities or any coupons of any series in any material respect or permit or facilitate the issuance of debt securities of any series in uncertificated form;

•

in the case of subordinated debt securities, to make any change in the provisions of the indenture relating to subordination that would limit or terminate the benefits available to any holder of senior indebtedness under such provisions (but only if each such holder of senior indebtedness consents to such change);

•

to add guarantees with respect to the debt securities or to secure the debt securities;

•

to make any change that does not adversely affect the rights of any holder in any material respect;

•

to add to, change, or eliminate any of the provisions of the indenture with respect to one or more series of debt securities, so long as any such addition, change, or elimination not otherwise permitted under the indenture will (a) neither apply to any debt security of any series created prior to the execution of such supplemental indenture and entitled to the benefit of such provision nor modify the rights of the holders of any such debt security with respect to such provision or (b) become effective only when there is no such debt security outstanding;

•

to evidence and provide for the acceptance of appointment by a successor or separate trustee with respect to the debt securities of one or more series and to add to or change any of the provisions of the indenture as will be necessary to provide for or facilitate the administration of the indenture by more than one trustee; or

TABLE OF CONTENTS

•

to establish the form or terms of debt securities and coupons of any series, as described under “— General” above.

Merger and Consolidation

The indenture provides that we will not consolidate with or merge with or into, or convey, transfer, or lease all or substantially all of our properties and assets to, another person, unless (i) the resulting, surviving, or transferee person, if not Booking Holdings Inc., is a corporation or limited liability company organized and existing under the laws of the United States of America, any state thereof or the District of Columbia; and (ii) immediately after giving effect to such transaction, no default has occurred and is continuing under the indenture; and (iii) the resulting, surviving or transferee person, if not Booking Holdings Inc., expressly assumes by supplemental indenture all of our obligations under the debt securities and the indenture. Upon any such consolidation, merger, or transfer, the resulting, surviving, or transferee person shall succeed to, and may exercise every right and power of, Booking Holdings Inc. under the indenture.

Satisfaction and Discharge of the Indenture; Defeasance

Unless otherwise provided for in the prospectus supplement, the indenture will generally cease to be of any further effect with respect to a series of debt securities if (i) we have delivered to the trustee for cancellation all debt securities of such series (with certain limited exceptions) or (ii) all debt securities and coupons of such series not theretofore delivered to the trustee for cancellation will have become due and payable, or are by their terms to become due and payable within one year or are to be called for redemption within one year, and we will have deposited with the trustee as trust funds the entire amount sufficient to pay at maturity or upon redemption all such debt securities and coupons (and if, in either case, we will also pay or cause to be paid all other sums payable under the indenture by us).

In addition, we will have a “legal defeasance option” (pursuant to which we may terminate, with respect to the debt securities of a particular series, all of our obligations under such debt securities and the indenture with respect to such debt securities) and a “covenant defeasance option” (pursuant to which we may terminate, with respect to the debt securities of a particular series, our obligations with respect to such debt securities under certain specified covenants contained in the indenture). If we exercise our legal defeasance option with respect to a series of debt securities, payment of such debt securities may not be accelerated because of an event of default. If we exercise our covenant defeasance option with respect to a series of debt securities, payment of such debt securities may not be accelerated because of an event of default related to the specified covenants.

The applicable prospectus supplement will describe the procedures we must follow in order to exercise our defeasance options.

Regarding the Trustee

The indenture provides that, except during the continuance of an event of default, the trustee will perform only such duties as are specifically set forth in the indenture. During the existence of an event of default, the trustee may exercise such rights and powers vested in it under the indenture and use the same degree of care and skill in its exercise as a prudent person would exercise under the circumstances in the conduct of such person’s own affairs.

The indenture and provisions of the Trust Indenture Act that are incorporated by reference therein contain limitations on the rights of the trustee, should it become one of our creditors, to obtain payment of claims in certain cases or to realize on certain property received by it in respect of any such claim as security or otherwise. The trustee will be permitted to engage in other transactions with us or any of our affiliates; provided, however, that if it acquires any conflicting interest (as defined in the indenture or in the Trust Indenture Act), it must eliminate such conflict or resign.

Governing Law

The indenture and the debt securities will be governed by the laws of the State of New York.

DESCRIPTION OF PREFERRED STOCK

The following description of the terms of the preferred stock we may issue sets forth certain general terms and provisions of any series of preferred stock to which any prospectus supplement may relate. Particular terms of the preferred stock offered by any prospectus supplement and the extent, if any, to which these general terms and provisions will apply to any series of preferred stock so offered will be described in the prospectus supplement relating to the applicable preferred stock. The applicable prospectus supplement may also state that any of the terms set forth in this description are inapplicable to such series of preferred stock. This description does not purport to be complete and is subject to and qualified in its entirety by reference to applicable Delaware law and the provisions of our certificate of incorporation relating to our preferred stock.

We currently have 150,000,000 authorized shares of preferred stock, par value $0.01 per share. Preferred stock may be issued independently or together with any other securities and may be attached to or separate from the other securities. As of August 3, 2023, we had no shares of preferred stock outstanding.

Pursuant to Delaware law and our certificate of incorporation, our board of directors has the authority to provide by resolution for the issuance of shares of preferred stock, in one or more classes or series, and to fix the rights, preferences, privileges, and restrictions thereof, including dividend rights, conversion rights, voting rights, terms of redemption, liquidation preferences, the number of shares constituting any series, and the designation of such series. The issuance of preferred stock could have the effect of decreasing the market price of our common stock and could adversely affect the voting and other rights of the holders of common stock. Our board of directors, in approving the issuance of a series of preferred stock and the applicable prospectus supplement, will set forth with respect to such series, the following:

•

the number of shares constituting such series;

•

the designation of such series;

•

the voting powers, if any, of the shares of such series; and

•

the preferences and relative, participating, optional, or other special rights, if any, and any qualifications, limitations, or restrictions thereof, of the shares of such series.

The terms of each series of preferred stock will be described in any prospectus supplement related to such series of preferred stock and will contain a discussion of any material U.S. federal income tax considerations applicable to an investment in the preferred stock.

DESCRIPTION OF DEPOSITARY SHARES

The following description of the terms of the depositary shares sets forth certain general terms and provisions of the depositary shares to which any prospectus supplement may relate. The particular terms of the depositary shares offered by any prospectus supplement and the extent, if any, to which these general provisions may apply to those depositary shares will be described in the prospectus supplement relating to those depositary shares. Accordingly, for a description of the terms of a particular issue of depositary shares, reference must be made to both the prospectus supplement relating thereto and to the following description.

We may, at our option, elect to offer fractional shares of preferred stock, rather than single shares of preferred stock (to be set forth in the prospectus supplement relating to a particular series of preferred stock). In the event we elect to do so, depositary receipts evidencing depositary shares will be issued.

•

The shares of any class or series of preferred stock represented by depositary shares will be deposited under a deposit agreement between us and one or more depositaries selected by us. Subject to the terms of the deposit agreement, each owner of a depositary share will be entitled, in proportion to the applicable fraction of a share of preferred stock represented by such depositary share, to all the rights and preferences of the shares of preferred stock represented by the depositary share, including dividend, voting, redemption, and liquidation rights.

•

The depositary shares will be evidenced by depositary receipts issued pursuant to the deposit agreement. Depositary receipts will be distributed to those persons purchasing the fractional shares of the related class or series of preferred shares in accordance with the terms of the offering described in the related prospectus supplement.

We may offer and sell the securities covered by this prospectus from time to time, in one or more transactions, at market prices prevailing at the time of sale, at prices related to market prices, at a fixed price or prices subject to change, at varying prices determined at the time of sale or at negotiated prices, by a variety of methods, including the following:

•

through agents;

•

to or through underwriters;

•

in “at the market offerings,” within the meaning of Rule 415(a)(4) under the Securities Act, to or through a market maker or into an existing trading market, on an exchange or otherwise;

•

through brokers or dealers;

•

directly by us to purchasers, including through a specific bidding, auction, or other process; or

•

through a combination of any of these methods of sale.

Registration of the securities covered by this prospectus does not mean that those securities necessarily will be offered or sold.

In effecting sales, brokers or dealers engaged by us may arrange for other brokers or dealers to participate. Broker-dealer transactions may include:

•

purchases of the securities by a broker-dealer as principal and resales of the securities by the broker-dealer for its account pursuant to this prospectus;

•

ordinary brokerage transactions; or

•

transactions in which the broker-dealer solicits purchasers.

In addition, we may sell any securities covered by this prospectus in private transactions or pursuant to Rule 144 under, or pursuant to other exemptions from registration under, the Securities Act rather than pursuant to this prospectus.

We may sell offered securities through agents designated by us from time to time. Any such agent in the offer or sale of the securities for which this prospectus is delivered will be named, and any commissions payable by us to that agent will be set forth, in the prospectus supplement to the extent required. Unless indicated in the prospectus supplement, such agents will have agreed to use their reasonable best efforts to solicit purchases for the period of their appointment.

In connection with the sale of securities covered by this prospectus, broker-dealers may receive commissions or other compensation from us in the form of commissions, discounts, or concessions. Broker-dealers may also receive compensation from purchasers of the securities for whom they act as agents or to whom they sell as principals or both. Compensation as to a particular broker-dealer may be in excess of customary commissions or in amounts to be negotiated. In connection with any underwritten offering, underwriters may receive compensation in the form of discounts, concessions, or commissions from us or from purchasers of the securities for whom they act as agents. Underwriters may sell the securities to or through dealers, and such dealers may receive compensation in the form of discounts, concessions, or commissions from the underwriters and/or commissions from the purchasers for whom they may act as agents. Any underwriters, broker-dealers, agents, or other persons acting on our behalf that participate in the distribution of the securities may be deemed to be “underwriters” within the meaning of the Securities Act, and any profit on the sale of the securities by them and any discounts, commissions, or concessions received by any of those underwriters, broker-dealers agents, or other persons may be deemed to be underwriting discounts and commissions under the Securities Act.

In connection with the distribution of the securities covered by this prospectus or otherwise, we may enter into hedging transactions with broker-dealers or other financial institutions. In connection with such transactions, broker-dealers or other financial institutions may engage in short sales of our securities in the course of hedging the positions they assume with us. We may also sell securities short and deliver the securities offered by this prospectus to close out our short positions. We may also enter into option or other

transactions with broker-dealers or other financial institutions, which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus, as supplemented or amended to reflect such transaction. We may also from time to time pledge our securities pursuant to the margin provisions of our customer agreements with our brokers. Upon our default, the broker may offer and sell such pledged securities from time to time pursuant to this prospectus, as supplemented or amended to reflect such transaction.

At any time a particular offer of the securities covered by this prospectus is made, a revised prospectus or prospectus supplement, if required, will be distributed which will set forth the aggregate amount of securities covered by this prospectus being offered and the terms of the offering. Such prospectus supplement, and, if necessary, a post-effective amendment to the registration statement of which this prospectus is a part, will be filed with the SEC to reflect the disclosure of additional information with respect to the distribution of the securities covered by this prospectus. In order to comply with the securities laws of certain states, if applicable, the securities sold under this prospectus may only be sold through registered or licensed broker-dealers. In addition, in some states the securities may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from registration or qualification requirements is available and is complied with.

In connection with an underwritten offering, we would execute an underwriting agreement with an underwriter or underwriters. Unless otherwise indicated in the revised prospectus or applicable prospectus supplement, such underwriting agreement would provide that the obligations of the underwriter or underwriters are subject to certain conditions precedent, and that the underwriter or underwriters with respect to a sale of the covered securities will be obligated to purchase all of the covered securities, if any such securities are purchased. We may grant to the underwriter or underwriters an option to purchase additional securities at the public offering price, less any underwriting discount, as may be set forth in the revised prospectus or applicable prospectus supplement. If we grant any such option, the terms of that option will be set forth in the revised prospectus or applicable prospectus supplement.

Underwriters, agents, brokers, or dealers may be entitled, pursuant to relevant agreements entered into with us, to indemnification by us against certain civil liabilities, including liabilities under the Securities Act that may arise from any untrue statement or alleged untrue statement of a material fact, or any omission or alleged omission to state a material fact in this prospectus, any supplement or amendment hereto, or in the registration statement of which this prospectus forms a part, or to contribution with respect to payments which the underwriters, agents, brokers or dealers may be required to make.
