                          CARNIVAL CORPORATION REPORTS
                      FOURTH QUARTER AND FULL YEAR EARNINGS

         MIAMI (12/20/01) - Carnival Corporation (NYSE:CCL) reported net income
of $116.3 million ($0.20 Diluted EPS) on revenues of $959.1 million for its
fourth quarter ended November 30, 2001, compared to net income of $193.8 million
($0.33 Diluted EPS) on revenues of $850.3 million for the same quarter in 2000.

         Net income for the year ended November 30, 2001, was $926.2 million
($1.58 Diluted EPS) on revenues of $4.54 billion, compared to net income of
$965.5 million ($1.60 Diluted EPS) on revenues of $3.78 billion for the same
period in 2000.

         Fourth quarter 2001 net income was reduced by $33 million, comprised of
an impairment charge of $39 million, primarily related to a write-down in the
carrying value of two ships, net of a Costa tax benefit of $6 million. Fourth
quarter 2000 included a Costa tax benefit of $27 million.

         The company's fourth quarter comparable cruise results were also
adversely affected by the September 11 terrorist attacks, which impacted all
leisure travel. The significant reduction in demand for travel following the
tragic events of September 11 resulted in the company reporting lower
occupancies and prices during the 2001 fourth quarter. Comparable net revenue
yields (net revenue per available berth day) for the quarter were down by
approximately 7 percent compared to the fourth quarter of 2000.

         Commenting on fourth quarter 2001 results, Carnival Corporation
Chairman and CEO Micky Arison said that "in light of the significant impact of
the September 11 events on the vacation market, the achievement of quarterly net
income of more than $116 million with occupancies of 98 percent is a testament
to the strength of our vacation products."

         Looking to 2002, Arison indicated that booking levels have started to
recover from the significant slowdown in bookings experienced in the two months
following September 11. During the last five weeks, net booking levels have been
45 percent above prior year levels, although cumulative advance bookings for
2002 still remain well behind last year's levels at this time. Arison also noted
that 2002 pricing has improved but is still below last year's levels.

2001 Fourth Quarter Earnings - 2 At the present time the company's advance booking occupancy levels for the first quarter of fiscal 2002, are approximately 92 percent, which is approximately seven percentage points behind the levels existing at the same time last year. Based on current pricing and booking trends, management presently expects that net revenue yields for the first quarter of 2002 will be down between 10 to 15 percent compared to last year. Bookings for the second and third quarters of fiscal 2002 are also behind last year's levels at this time with occupancy down by approximately 11 percentage points each quarter. Pricing on these bookings is also down from the prior year. Arison indicated that, given the current booking trends, he is optimistic that net revenue yield comparisons for the remainder of 2002 will improve compared to the first quarter. The company also recently changed the delivery schedule for Holland America's Vista-class newbuilds, assigning one slot to Cunard Line and signing an option on a fifth newbuild. The new delivery schedule for Holland America is as follows: Zuiderdam, November 2002; Oosterdam, June 2003; Vista #3, April 2004; Vista #4, October 2005; and option ship, May 2006. The new 85,000-ton Cunard ship is scheduled for delivery in January 2005, and will target the U.K. vacation market. Based on these new delivery dates, the company's shipbuilding commitments for the fiscal years 2002 through 2005 are now estimated to be approximately $1.75 billion, $1.5 billion, $2.0 billion and $700 million, respectively. In addition, the year over year percentage increase in the company's average passenger capacity resulting from the delivery of ships currently under contract for fiscal 2002 through 2006 is expected to approximate 4.5 percent, 16.5 percent, 17.3 percent, 10.6 percent and 2.5 percent, respectively. Carnival does not expect to reschedule any further deliveries. Arison pointed out that the company continues to be confident that the fundamental long-term drivers of its growth remain intact. "To enable us to overcome challenges in these times of increased uncertainty, as well as to take advantage of opportunities as they present themselves, it is important for us to maintain our solid operating margins and strong balance sheet." Carnival currently has more than $2.4 billion of cash, short-term investments and undrawn credit lines, and also relatively low debt levels. As a result of its financial strength and operating results, the company believes that it maintains the highest credit ratings in the leisure industry. On December 16, 2001, the company announced its pre-conditional offer to acquire P&O Princess Cruises plc for approximately $4.6 billion in cash and Carnival common stock. [Note 2] [Note 3] - more -
