Section 1—Conflict Minerals Disclosure

Item 1.01 Conflict Minerals Disclosure and Report

This is the Form SD of Carnival Corporation and Carnival plc (together, the “Corporation”) for the calendar year 2019. Certain terms in this report are defined in Rule 13p-1 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

In accordance with Exchange Act Rule 13p-1, the Corporation undertook inquiries to determine whether there was reason to believe that any “conflict minerals” necessary to the functionality or production of any product contracted by the Corporation to me manufactured originated in the Democratic Republic of the Congo (“DRC”) or an adjoining country (together with the DRC, the “Covered Countries”). Conflict minerals are defined in Section 1502(e)(4) of the Act as columbite-tantalite, also known as coltan (the metal ore from which tantalum is extracted); cassiterite (the metal ore from which tin is extracted); gold; wolframite (the metal ore from which tungsten is extracted) or their derivatives.

This report on Form SD and the information disclosed herein is publicly available on the Corporation’s website here: www.carnivalcorp.com/financial-information/sec-filings/all.

Reasonable Country of Origin Inquiry (“RCOI”)

The Corporation implemented a process intended to ensure compliance with Rule 13p-1. Specifically, the Corporation engaged in a review of those products it contracts to manufacture in order to identify any products that contain conflict minerals. The outcome of this review was that gold (which is a conflict mineral) was contained in certain jewelry items it contracted for manufacture in 2019. The gold supplier for such products provided the Corporation with a certification confirming that none of its gold products contain conflict minerals originating from the Covered Countries.

Based on its RCOI described above, the Corporation has no reason to believe the necessary conflict minerals (the gold present in jewelry products manufactured during the calendar year 2019) originated in the Covered Countries.

Section 2—Exhibits

Item 2.01 Exhibits

Based on the above RCOI, no Conflict Minerals Report is required.
