A shareholder who is entitled to attend, speak and vote at the Carnival plc General Meeting may appoint one or more proxies to attend, speak and vote instead of that shareholder. Voting will take place on a poll. A proxy need not be a shareholder of the Company. A shareholder wishing to appoint someone other than the Chair of the Meeting as their proxy should insert that person's name in the space provided. If the proxy is being appointed for less than your full entitlement, please indicate in the box next to the appointed proxy's name the number of shares in relation to which that person is authorized to act as your proxy. If left blank, your proxy will be deemed to be authorized in respect of your full voting entitlement or, if this Form of Proxy has been issued in respect of a designated account for a shareholder, the full voting entitlement for that designated account. 4. A shareholder who appoints more than one proxy must appoint each proxy to exercise the votes attaching to specified shares held by that shareholder. To appoint more than one proxy, additional proxy cards may be obtained by visiting the website of our Registrar, Equiniti, at www.shareview.co.uk, or you may photocopy this proxy card. Please indicate in the box next to the proxy holder's name the number of shares in relation to which they are authorized to act as your proxy. Please also indicate by ticking the box provided if the proxy instruction is one of multiple instructions being given. All proxy cards must be signed and should be returned together in the same envelope. When two or more valid proxy appointments are delivered or received in respect of the same share for use at the same meeting, the one which was executed last shall be treated as replacing and revoking the others in their entirety as regards that share. If the Company is unable to determine which was executed last, none of them shall be valid in respect of that share. 5. To be valid, your signed and dated proxy card must be completed, signed and deposited together with any power of attorney or authority under which it is signed or a certified copy of such power of attorney or authority (whether delivered personally or by post), at the offices of the Company’s registrar, Equiniti Limited, Aspect House, Spencer Road, Lancing BN99 6DA, as soon as possible and no later than 1:40 p.m. (BST) on April 15, 2026 (or, in the case of an adjournment, not later than 48 hours before the time fixed for the adjourned meeting (excluding any part of such 48-hour period falling on a non-working day)).

Unless instructed otherwise, your proxy will have discretion to vote or abstain from voting as they see fit on the resolution and any other business which may properly come before the meeting, including amendments to resolution, and at any adjournment of the meeting. 7. The Abstain box is provided to enable you to abstain on any particular resolution. However, it should be noted that a vote ‘Abstain’ is not a vote in law and will not be counted in the calculation of the proportion of votes ‘For’ and ‘Against’ a resolution but will be counted to establish if a quorum is present. 8. Shareholders are entitled to vote online at www.shareview.co.uk. First, please log in to your Shareview Portfolio. Once you have logged in, simply click ‘View’ on the ‘My Investments’ page and then click on the link to vote and follow the on-screen instructions. If you have not yet registered for a Shareview Portfolio, please go to www.shareview.co.uk and enter the requested information. Alternatively, CREST members can submit their proxy through the CREST Electronic Proxy Appointment Service (ID RA19). 9. In the case of joint holders, the signature of one holder on a proxy card will be accepted and the vote of the senior holder who tenders a vote, whether in person or by proxy, shall be accepted to the exclusion of the votes of the other joint holders. For this purpose, seniority shall be determined by the order in which the names stand on the register of members of the Company in respect of the relevant joint holding. 10. Any corporation which is a shareholder can appoint one or more corporate representatives who may exercise, on its behalf, all of its powers as a shareholder provided that they do not do so in relation to the same shares. The corporate representative may be required to produce to Equiniti their written authority to attend, speak and vote at the meeting at any time before the start of the Carnival plc General Meeting. The representative shall not be entitled to exercise the powers conferred on them by the shareholder until any such demand has been satisfied. 11. To appoint one or more proxies or to give an instruction to a proxy (whether previously appointed or otherwise) via the CREST system, CREST messages must be received by the issuer’s agent (ID RA19) by 1:40 p.m. (BST) on April 15, 2026 (or, in the case of an adjournment, not later than 48 hours before the time fixed for the adjourned meeting (excluding any part of such 48-hour period falling on a non-working day)). For this purpose, the time of receipt will be taken to be the time (as determined by the timestamp generated by the CREST system) from which the issuer’s agent is able to retrieve the message. The Company may treat as invalid a proxy appointment sent by CREST in the circumstances set out in Regulation 35(5)(a) of the Uncertificated Securities Regulations. 12. If you are an institutional investor, you may also be able to appoint a proxy electronically via the Proxymity platform. Before you can appoint a proxy via this process you will need to have agreed to Proxymity’s associated terms and conditions. It is important that you read these carefully as you will be bound by them and they will govern the electronic appointment of your proxy. 13. Return of this proxy card will not prevent a registered shareholder from attending the meeting and voting in person. 14.
