Senior Notes

On May 7, 2026, Booking Holdings Inc. (the “Company”) executed an Officers’ Certificate (the “Officers’ Certificate”), in accordance with Sections 2.02 and 10.04 of the Indenture dated August 8, 2017 (the “Base Indenture” and, together with the Officers’ Certificate, the “Indenture”) between the Company and U.S. Bank Trust Company, National Association (as successor in interest to U.S. Bank National Association), as trustee (the “Trustee”) and registrar, in connection with the sale of $750,000,000 aggregate principal amount of the Company’s 5.375% Senior Notes due 2036 (the “Senior Notes”). The Senior Notes will mature on May 7, 2036, unless earlier redeemed or repurchased. The Senior Notes are the Company’s general senior unsecured obligations and rank equally with the Company’s other senior unsecured obligations.

The Company will pay interest on the Senior Notes at a semi-annual rate of 5.375% payable on May 7 and November 7 of each year, beginning on November 7, 2026.

Prior to February 7, 2036, the date that is three months prior to the maturity date of the Senior Notes (the “Par Call Date”), the Company may redeem some or all of the Senior Notes at a redemption price equal to the greater of the following amounts plus, in each case, accrued and unpaid interest thereon, if any, to, but excluding, the redemption date: (1) 100% of the aggregate principal amount of the Senior Notes to be redeemed and (2) the sum of the present values of the remaining scheduled payments of principal and interest on the Senior Notes to be redeemed that would be due if such Senior Notes matured on the Par Call Date, not including any portion of the payments of interest accrued to the date of redemption, discounted to such redemption date on a semi-annual basis at the Treasury Rate (as defined in the Officers’ Certificate), plus 15 basis points. The Company may also redeem some or all of the Senior Notes on or after the Par Call Date at 100% of the principal amount of the Senior Notes, plus accrued and unpaid interest, if any, to, but excluding, the redemption date.

The Indenture contains customary events of default with respect to the Senior Notes, including failure to make required payments, failure to comply with certain agreements or covenants, acceleration of certain other indebtedness, and certain events of bankruptcy and insolvency. Events of default under the Indenture arising from certain events of bankruptcy or insolvency will automatically cause the acceleration of the amounts due under the Senior Notes. If any other event of default under the Indenture occurs and is continuing with respect to a series of Senior Notes, the Trustee or the holders of at least 25% in aggregate principal amount of the then outstanding Senior Notes of such series may declare the acceleration of the amounts due under the Senior Notes of such series.

The foregoing description of the Senior Notes is qualified in its entirety by reference to the full text of the Base Indenture, which was previously filed as Exhibit 4.4 to the Company’s shelf registration statement on Form S-3 (Registration File No. 333-273678) (the “Registration Statement”), the Form of Senior Note, which is filed as Exhibit 4.1, the Officers’ Certificate relating to the Senior Notes, which is filed as Exhibit 4.2, each of which is incorporated by reference.
