**A.**Stock Swap Program

Our Stock Swap Program allows us to realize a net cash benefit when Carnival Corporation common stock is trading at a premium to the price of Carnival plc ordinary shares. Under the Stock Swap Program, we may elect to offer and sell shares of Carnival Corporation common stock at prevailing market prices in ordinary brokers’ transactions and repurchase an equivalent number of Carnival plc ordinary shares in the UK market.

Under the Stock Swap Program effective June 2021, the Boards of Directors authorized the sale of up to $500 million of shares of Carnival Corporation common stock in the U.S. market and the repurchase of an equivalent number of Carnival plc ordinary shares.

We may in the future implement a program to allow us to realize a net cash benefit when Carnival plc ordinary shares are trading at a premium to the price of Carnival Corporation common stock.

Any sales of Carnival Corporation common stock and Carnival plc ordinary shares have been or will be registered under the Securities Act of 1933, as amended. Since the beginning of the Stock Swap Program, first authorized in June 2021, we have sold 17.2 million shares of Carnival Corporation common stock and repurchased the same amount of Carnival plc ordinary shares, resulting in net proceeds of $29 million. During the three months ended May 31, 2024, there were no sales or repurchases under the Stock Swap Program. During the three months ended May 31, 2024, no shares of Carnival Corporation common stock or Carnival plc ordinary shares were repurchased.
