On September 29, 2025, Carnival Corporation & plc issued a press release entitled “CARNIVAL CORPORATION & PLC ACHIEVES ALL-TIME HIGH FINANCIAL RESULTS WITH NET INCOME OF $1.9 BILLION (ADJUSTED NET INCOME OF $2 BILLION).” A copy of ~~this~~the press release is ~~furnished~~attached hereto as Exhibit 99.1 toand ~~this~~is ~~report.~~incorporated ~~This~~by ~~information~~reference ~~shall~~herein. ~~not~~Such bepress ~~deemed~~release ~~“filed”~~includes ~~for~~forward-looking ~~purposes~~statements. ofSee ~~Section~~“Cautionary Note 18Concerning ofForward-Looking ~~the~~Statements” ~~Securities~~within ~~Exchange~~the ~~Act~~press ofrelease ~~1934,~~for asadditional ~~amended,~~information. ~~and~~Neither isthis ~~not~~current ~~incorporated~~report ~~by reference into any filing of either Carnival Corporation or Carnival plc, whether made before or after~~ nor the ~~date~~press ofrelease ~~this~~constitutes ~~report,~~a ~~regardless~~notice of ~~any~~redemption ~~general~~with ~~incorporation~~respect ~~language~~to in the ~~filing~~2029 Unsecured Notes.

~~Section~~The 7Company is furnishing the information in this Current Report on Form 8-K, including Exhibit 99.1 hereto, to comply with Regulation FD. ~~Disclosure~~Such information shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, 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 of 1933, as amended, or the Securities Exchange Act of 1934, as amended, 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.

Item 7.01 - Regulation FD Disclosure.

On September 29, 2025, pursuant to the indenture, dated as of November 18, 2022 (the “Convertible Notes Indenture”), by and among Carnival Corporation (the “Company”), Carnival plc, the other guarantors party thereto and U.S. Bank Trust Company, National Association, as trustee, the Company issued a notice of redemption for the entire outstanding principal amount of its 5.75% convertible senior notes due 2027 (the “Convertible Notes”) to be redeemed on December 5, 2025 (the “Redemption Date”) at a redemption price equal to 100.0% of the principal amount of the Convertible Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the Redemption Date.

As a result of the Company’s call for redemption of the Convertible Notes, the Convertible Notes are convertible, at the option of the holder, at any time prior to 5:00 p.m., New York City time, on December 3, 2025, the second scheduled trading day immediately preceding the Redemption Date (the “Conversion Period”).

On September 26, 2025, the Conversion Rate (as defined in the Convertible Notes Indenture) of the Convertible Notes was 74.6714 shares of the Company’s common stock per $1,000 principal amount of Convertible Notes. Because of the Company’s call for redemption of the Convertible Notes, holders of the Convertible Notes electing to convert their Convertible Notes during the Conversion Period are entitled to 2.5589 additional shares of the Company’s common stock per $1,000 principal amount of Convertible Notes converted.

The settlement method for the Convertible Notes surrendered for conversion will be Combination Settlement (as defined in the Convertible Notes Indenture), with a Specified Dollar Amount (as defined in the Convertible Notes Indenture) of $442.0960 per $1,000 principal amount of Convertible Notes and the remainder settled in shares of the Company’s common stock in accordance with the terms of the Convertible Notes Indenture. Assuming all of the Convertible Notes are converted, the total amount of cash paid to the holders will be $500 million. Pursuant to the terms of the Convertible Notes Indenture, the total number of shares of the Company’s common stock to be issued will depend on the market price of the Company’s common stock during the observation period that will be used to determine the total settlement amount.

This redemption is a continuation of the Company’s strategy to deleverage and reduce interest expense. This current report does not constitute a notice of redemption with respect to the Convertible Notes.

The Company is furnishing the information in 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, 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 of 1933, as amended, or the Securities Exchange Act of 1934, as amended, 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.
