Notification to Untraced Shareholders

MIAMI (April 24, 2026) – Carnival plc (LSE: CCL; NYSE CUK) (“Carnival”) announces that it initiated a tracing exercise earlier this year to trace certain shareholders with whom Carnival and its registrar had lost contact for a period of at least 12 years (the “Untraced Shareholders”) to help reunite those shareholders with their unclaimed entitlements.

Carnival gives notice that, in accordance with its articles of association, the shares of each Untraced Shareholder who has not contacted Carnival or its registrar since the commencement of the tracing exercise have been sold. Each Untraced Shareholder is invited to claim the net proceeds of the sale of their shares and any unclaimed payments, including dividends, to which that shareholder is entitled (the “Payments”) by contacting Equiniti Limited by telephone at +44 (0) 371 384 2665 (lines open Monday to Friday 8:30am-5:30pm BST) or online at www.Shareview.co.uk by April 24, 2027.

If no valid claim has been received by Equiniti Limited by April 24, 2027, the Payments will be forfeited by each Untraced Shareholder and will belong to Carnival.
