Item 5.07 – Submission of Matters to a Vote of Security Holders.

Annual Meetings

The annual meetings of shareholders of Carnival Corporation and Carnival plc were held on April 17, 2026 (the “Annual Meetings”). On all matters which came before the Annual Meetings, holders of Carnival Corporation common stock and Carnival plc ordinary shares were entitled to one vote for each share held. Proxies for 1,205,637,579 shares entitled to vote were received in connection with the Annual Meetings.

All of the nominees were elected at the Annual Meetings to serve as directors of Carnival Corporation and Carnival plc until the next annual meetings of shareholders. Carnival Corporation and Carnival plc’s shareholders also approved all other proposals that were submitted at the Annual Meetings, as recommended by the Boards of Directors.

The matters which were submitted to Carnival Corporation and Carnival plc’s shareholders for approval at the Annual Meetings and the tabulation of the final votes with respect to each such matter were as follows:

Director Elections.

Carnival plc Court Meeting

In addition, the Carnival plc Court Meeting (the “Court Meeting”) was held on April 17, 2026, in connection with the proposed unification of Carnival Corporation and Carnival plc’s dual listed company structure and the redomiciliation of Carnival Corporation from Panama to Bermuda (the “DLC Unification and Redomiciliation Transactions”).

The table below sets out the results of the poll at the Court Meeting. Each Scheme Shareholder present (in person or by proxy) was entitled to one vote per Scheme Share held at 6:30 p.m. BST on April 15, 2026. In summary, the requisite majority of Scheme Shareholders present and voting (in person or by proxy), being a majority in number of Scheme Shareholders present and voting (either in person or by proxy) voted in favor of the Scheme at the Court Meeting, and they represented not less than 75 per cent. in value of the Scheme Shares held by such Scheme Shareholders.

Notes:

* Where a Scheme Shareholder cast some of their votes "FOR" and some of their votes "AGAINST" the resolution, such Scheme Shareholder has been counted as having voted both "FOR" and "AGAINST" the resolution for the purposes of determining the number and percentage of Scheme Shareholders who voted.

** All percentages have been rounded to the nearest two decimal places.

*** The aggregate of Scheme Shareholders voting "FOR" and "AGAINST" the resolution as set out in this row exceeds the total number and percentage of Scheme Shareholders who voted because 14 registered members gave instructions for votes to be cast "FOR" the resolution in respect of part of their holding of Scheme Shares and "AGAINST" the resolution in respect of another part of their holding of Scheme Shares.

Special Meetings

The Carnival plc General Meeting of shareholders and the Carnival Corporation Extraordinary General Meeting of shareholders (collectively, the “Special Meetings”) were held on April 17, 2026, in connection with the DLC Unification and Redomiciliation Transactions. On all matters which came before the applicable Special Meeting, holders of Carnival Corporation common stock and Carnival plc ordinary shares were entitled to one vote for each share held.

Proxies for 70,153,263 shares entitled to vote were received in connection with the Carnival plc General Meeting of shareholders. Proxies for 845,904,932 shares entitled to vote were received in connection with the Carnival Corporation Extraordinary General Meeting. Carnival Corporation and Carnival plc’s shareholders approved all proposals that were submitted at the Special Meetings, as recommended by the Boards of Directors.

The matters which were submitted to Carnival plc’s and Carnival Corporation’s shareholders for approval at the Special Meetings and the tabulation of the final votes with respect to each such matter were as follows:

Notes:

1 An "abstained" vote is not a vote in law and is not counted in the calculation of the proportion of votes "FOR" or "AGAINST" the resolution.

2 Resolutions 1, 4, 5 and 6 are class rights actions. Each of these resolutions were approved by the requisite majorities of Carnival plc Shareholders and Carnival Corporation Shareholders voting separately (and excluding the holder of the Carnival plc special voting share and the holder of the Carnival Corporation special voting share). The number of votes "FOR" and "AGAINST" resolutions that are class rights actions are therefore different and lower than the number of votes "FOR" and "AGAINST" resolutions that are joint electorate actions.
