TABLE OF CONTENTS

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.

RISK FACTORS

Investing in our securities involves risks. Potential investors are urged to read and consider the risk factors and other disclosures relating to an investment in securities issued by us described in our Annual Report on Form 10-K for the fiscal year ended December 31, 2025 and our Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2026, as updated by annual, quarterly, and other reports and documents we file with the SEC after the date of this prospectus and that are incorporated by reference herein.

The risks and uncertainties we have described are not the only ones we face. Additional risks and uncertainties not presently known to us or that we currently consider immaterial may also affect our business operations. To the extent a particular offering implicates additional known material risks, we will include a discussion of those risks in the applicable prospectus supplement.

USE OF PROCEEDS

Unless otherwise indicated in a prospectus supplement, we intend to use the net proceeds from the sale of our securities for general corporate purposes, which may include future repayments of indebtedness, share repurchases, and corporate acquisitions, or for such other purposes as may be specified in the applicable prospectus supplement.

DESCRIPTION OF COMMON STOCK

We currently have 25,000,000,000 authorized shares of common stock, par value $0.008 per share. This authorized share amount reflects the 25-for-1 stock split that the Company effected on April 2, 2026. Common stock may be issued independently or together with any other securities and may be attached to or separate from the other securities. As of July 27, 2026, we had 751,380,500 shares of common stock outstanding.

Subject to preferences that may apply to shares of preferred stock outstanding at the time, the holders of outstanding shares of common stock are entitled to receive dividends out of assets legally available therefore at such times and in such amounts as the board of directors may from time to time determine. Each stockholder is entitled to one vote for each share of common stock held on all matters submitted to a vote of stockholders. Cumulative voting for the election of directors is not provided for in our restated certificate of incorporation, as amended (our "certificate of incorporation"), which means that the holders of a majority of the shares voted can elect all of the directors then standing for election. The common stock is not entitled to preemptive rights and is not subject to conversion or redemption. Upon the occurrence of a liquidation, dissolution or winding-up, the holders of shares of common stock would be entitled to share ratably in the distribution of all of our assets remaining available for distribution after satisfaction of all our liabilities and the payment of the liquidation preference of any outstanding preferred stock. Each outstanding share of common stock is fully paid and nonassessable.

DESCRIPTION OF DEBT SECURITIES

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

We may issue debt securities from time to time in one or more series. The debt securities will be general obligations of Booking Holdings Inc. The debt securities may be fully and unconditionally guaranteed on a secured or unsecured senior or subordinated basis, jointly and severally, by guarantors, if any. In the event that any series of debt securities will be subordinated to other indebtedness that we have outstanding or may incur, the terms of the subordination will be set forth in the prospectus supplement relating to the subordinated debt securities. Debt securities will be issued under one or more indentures (the "indenture") between us and one or more trustees named in the prospectus supplement (the "trustee"). The indenture has been filed as an exhibit to the registration statement of which this prospectus is a part. The following discussion of certain provisions of the indenture is a summary only and is qualified by reference to the provisions of the indenture, including the definition of certain terms used below. You should refer to the indenture for the complete terms of the debt securities.

​

Unless otherwise provided in the applicable prospectus supplement, securities in registered form may be transferred or exchanged at the office of the trustee at which its corporate trust business is principally administered in the United States or at the office of the trustee or the trustee's agent at which its corporate agency business is conducted, subject to the limitations provided in the indenture, without the payment of any service charge, other than any tax or governmental charge payable in connection therewith. Securities in bearer form will be transferable only by delivery. Provisions with respect to the exchange of securities in bearer form will be described in the prospectus supplement relating to those securities in bearer form.

All funds that we pay to a paying agent for the payment of principal, premium, or interest with respect to any debt securities that remain unclaimed at the end of two years after that principal, premium or interest

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

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

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

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

​

•

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

​

•

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.

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.

As of August 4, 2026, 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

Each series of warrants will be issued under a separate warrant agreement to be entered into between us and a bank or trust company, as warrant agent.

The depositary shares will be evidenced by depositary receipts issued pursuant to the deposit agreement.

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.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 14. Other Expenses of Issuance and Distribution

The following table sets forth the estimated costs and expenses, other than underwriting discounts and commissions, payable by Booking Holdings Inc. (the "registrant") in connection with the sale or distribution of the securities registered under this registration statement.

​

*

Under Rules 456(b) and 457(r) of the Securities Act, applicable SEC registration fees have been deferred and will be paid at the time of any particular offering of securities under this registration statement, and are therefore not estimable at this time.

​

**

Because an indeterminate amount of securities is covered by this registration statement, the expenses in connection with the issuance and distribution of the securities are not currently determinable.

Item 15. Indemnification of Directors and Officers

Section 145 of the Delaware General Corporation Law (the "DGCL") empowers a Delaware corporation to indemnify any persons who are, or are threatened to be made, parties to any threatened, pending, or completed legal action, suit or proceeding, whether civil, criminal, administrative, or investigative (other than an action by or in the right of such corporation) by reason of the fact that such person is or was an officer, director, employee, or agent of such corporation, or is or was serving at the request of such corporation as a director, officer, employee, or agent of another corporation, partnership, joint venture, trust, or other enterprise. The indemnity may include expenses (including attorneys' fees), judgments, fines, and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit, or proceeding, provided that such officer, director, employee, or agent acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the corporation's best interests, and, for criminal proceedings, had no reasonable cause to believe his or her conduct was unlawful. A Delaware corporation may indemnify officers and directors in an action by or in the right of the corporation under the same conditions, except that no indemnification is permitted without judicial approval if the officer or director is adjudged to be liable to the corporation. Where an officer or director is successful on the merits or otherwise in the defense of any action referred to above, the corporation must indemnify him or her against the expenses that such officer or director actually and reasonably incurred.

Article Seven of our certificate of incorporation provides that:

(1) we shall indemnify our directors and officers to the fullest extent authorized or permitted by law, provided that any proceeding initiated by any director or officer (other than a proceeding to enforce rights to indemnification) must be authorized or consented to by our board of directors;

(2) we may, to the extent authorized from time to time by our board of directors, indemnify our other employees and agents to the extent that we indemnify our officers and directors;

(3) the right to indemnification in Article Seven includes the right to be paid by us the expenses incurred in defending or otherwise participating in any proceeding in advance of its final disposition; and

(4) the rights conferred in Article Seven are not exclusive of any other right any person may have or acquire under our certificate of incorporation, our amended and restated by-laws, any statute, agreement, vote of stockholders of the Company or disinterested directors of the Company or otherwise.

Section 145 of the DGCL permits a corporation to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee, or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee, or agent of another corporation, partnership, joint venture, trust, or other enterprise against any liability asserted against such person and incurred by such person in such capacity, or arising out of their status as such, whether or not the corporation would have the power to indemnify such person against such liability. We have obtained officers' and directors' liability insurance for the members of our board of directors and executive officers for certain losses arising from claims or charges made against them while acting in their capacities as directors and officers of the Company.

In addition, Section 102(b)(7) of the DGCL provides that the certificate of incorporation of a corporation may contain a provision eliminating or limiting the personal liability of a director or officer to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, provided that such provision shall not eliminate or limit the liability of a director or officer: (i) for any breach of the director's or officer's duty of loyalty to the corporation or its stockholders; (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law; (iii) under Section 174 of the DGCL; (iv) for any transaction from which the director or officer derived an improper personal benefit; or (v) in the case of officers only, for any action by or in the right of the corporation. Article Five of our certificate of incorporation includes a provision that eliminates the personal liability of our directors or officers for monetary damages for breach of their fiduciary duty as directors to the fullest extent permitted by the DGCL.

We have also entered into indemnification agreements with certain officers of the Company and its subsidiaries, indemnifying each such person against losses, liabilities, and expenses arising out of any claims made against such person by reason of his or her being a director or officer of the Company. Among other exclusions, we shall not indemnify any person with respect to claims involving any breach of the duty of loyalty; willful or intentional misconduct, gross negligence, or a knowing and willful violation of law; unlawful payment of a dividend or distribution or unlawful stock or equity purchase or redemption; or any receipt of an improper personal benefit.

Set forth below is a list of exhibits that are being filed or incorporated by reference into this prospectus:

​

*

To be filed, if necessary, as an exhibit to a post-effective amendment to this registration statement or as an exhibit to a Current Report on Form 8-K to be filed by the registrant in connection with a specific offering, and incorporated herein by reference.

​

Item 17. Undertakings

(a) The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement (notwithstanding the foregoing, any increase or decrease in the volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement); and

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided, however, that paragraphs (i), (ii) and (iii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement;

(2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof;

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering;

(4) That, for the purpose of determining liability under the Securities Act to any purchaser:

(i) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(ii) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus (as provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof); provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date; and

(5) That, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv) Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(b) The undersigned registrant hereby further undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant's annual report pursuant to Section 13(a) or 15(d) of

the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) For an offering in which the securities to be registered are to be offered to existing security holders pursuant to warrants or rights and any securities not taken by security holders are to be reoffered to the public, the undersigned registrant hereby undertakes to supplement the prospectus, after the expiration of the subscription period, to set forth the results of the subscription offer, the transactions by the underwriters during the subscription period, the amount of unsubscribed securities to be purchased by the underwriters, and the terms of any subsequent reoffering thereof. If any public offering by the underwriters is to be made on terms differing from those set forth on the cover page of the prospectus, a post-effective amendment will be filed to set forth the terms of such offering.

(d) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

(e) The undersigned registrant hereby undertakes, if applicable, to file an application for the purpose of determining the eligibility of any trustee to act under subsection (a) of Section 310 of the Trust Indenture Act in accordance with the rules and regulations prescribed by the SEC under Section 305(b)(2) of the Trust Indenture Act.

SIGNATURES

Pursuant to the requirements of the Securities Act, the registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Norwalk, State of Connecticut, on August 4, 2026.
