CCL: Company disclosure

Item 7.01 Regulation FD Disclosure. On August 5, 2026, Carnival Corporation Ltd. (the “Company”) issued a notice of redemption for all of the $500,000,000 aggregate principal amount of its 7.000% First-Priority Senior Secured Notes due 2029 (the “2029 Notes”) to be redeemed on August 15, 2026 (the “Redemption Date”) at a redemption price equal to 103.50% of the principal amount of the 2029 Notes. Because the Redemption Date will fall on an interest payment date, accrued and unpaid interest will be paid to the holders registered as such at the close of business on July 31, 2026 (the record date preceding the August 15, 2026 interest payment date). On June 25, 2026, pursuant to the indenture governing the 2029 Notes, the collateral securing the 2029 Notes fell away upon the Company’s receipt of a second investment grade credit rating, resulting in the 2029 Notes becoming unsecured. The Company is furnishing the information in Item 7.01 of this Current Report on Form 8-K to comply with Regulation FD. Such information shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, and shall not be deemed to be incorporated by reference into any of the Company’s filings under the Securities Act or the Exchange Act, whether made before or after the date hereof and regardless of any general incorporation language in such filings, except to the extent expressly set forth by specific reference in such filing. SIGNATURES Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
