CARNIVAL CORPORATION & PLC REPORTS

THIRD QUARTER EARNINGS

MIAMI (September 21, 2010) – Carnival Corporation & plc (NYSE/LSE: CCL; NYSE: CUK) reported net income of $1.3 billion, or $1.62 diluted EPS, on revenues of $4.4 billion for its third quarter ended August 31, 2010. Net income for the third quarter of 2009 was $1.1 billion, or $1.33 diluted EPS, on revenues of $4.1 billion.

Carnival Corporation & plc Chairman and CEO Micky Arison noted that earnings per share for the third quarter 2010 increased 22 percent over 2009 and were just 3 percent shy of third quarter record profits. The third quarter 2010 operating results were significantly better than anticipated in the company’s June guidance due to the combination of higher than expected revenue yields and lower than expected unit costs.

Commenting on the third quarter, Arison said, “Despite ongoing economic concerns, cruise ticket prices remained strong close to sailing rewarding consumers that booked early. We enjoyed robust demand across all products during our seasonally strong summer period. Our North American brands experienced a significant rebound in peak season revenue yields, increasing more than 10 percent over weak 2009 comparisons. Revenue yields for our European brands, which absorbed an 8 percent capacity increase, were up 1 percent (constant dollars) cycling relatively strong performance in the prior year. At the same time, our ongoing cost control efforts continued to bear fruit as we drove down operating, selling and administrative costs globally.”

Key metrics for the third quarter 2010 compared to the prior year were as follows:

• On a constant dollar basis net revenue yields (net revenue per available lower berth day) increased 6.2 percent for 3Q 2010, which was slightly above the company’s June guidance, up 5 to 6 percent. Net revenue yields in current dollars increased 2.5 percent due to unfavorable currency exchange rates. Gross revenue yields increased only 1.2 percent in current dollars driven by lower air transportation revenue.

• Excluding fuel, net cruise cost per available lower berth day (“ALBD”) declined 2.4 percent in constant dollars, which was significantly better than June guidance, up 1 to 2 percent.

• Including fuel, net cruise costs per ALBD increased 0.6 percent on a constant dollar basis (decreased 1.8 percent in current dollars). Gross cruise costs per ALBD decreased 2.8 percent in current dollars.

• Fuel prices increased 17 percent to $473 per metric ton for 3Q 2010 from $405 per metric ton in 3Q 2009 but were slightly lower than June guidance of $493 per metric ton.

• The third quarter 2010 was impacted by two unusual items, which reduced earnings by $24 million ($0.03 per share) – a $41 million charge to operating expense relating to a billing from the British Merchant Navy Officers Pension Fund partially offset by a $17 million litigation settlement.

Continuing with its strategic growth initiatives, the company took delivery of Holland America Line’s 2,106-passenger Nieuw Amsterdam, and signed a new ship order with Germany’s Meyer Werft for the construction of a 2,192-passenger cruise ship for AIDA Cruises to be delivered spring 2013. This marks the seventh new ship ordered for the flourishing German cruise market in the past six years.

2010 Outlook

Since June, booking volumes for the remainder of 2010 and the first half 2011 are running ahead of the prior year at prices in line with prior year levels. At this time, cumulative advance bookings for the remainder of the year and the first half 2011 are at higher prices (constant dollars) with occupancies for the fourth quarter 2010 in line with the prior year and for the first half 2011 slightly behind last year.

Arison noted, “The booking environment has remained solid and we expect revenue yields to continue to improve in 2011 and beyond as the economy regains its footing. Consumers continue to embrace vacations as a much needed escape from the rigors of daily life, while cruising remains an increasingly attractive option for those seeking greater value for their vacation dollar.”

The company expects full year 2010 net revenue yields, on a constant dollar basis, to increase 2.5 percent, in line with its June guidance of an increase of 2 to 3 percent. However, currency exchange rates have moved favorably since June guidance was provided. As a result, the company now expects net revenue yields on a current dollar basis to increase 1 percent for the full year 2010 compared to 2009.

Based primarily on lower costs achieved in the third quarter, the company now expects net cruise costs excluding fuel per ALBD for the full year 2010 to be down 4 percent on a constant dollar basis, which is better than its June guidance of down 2.5 to 3.5 percent. Since June guidance, favorable changes in currency exchange rates have increased earnings by $30 million. In addition, a decline in fuel prices has reduced forecasted fuel costs by $27 million. Based on current spot prices, fuel costs for full year 2010 are now expected to increase $410 million compared to 2009, costing an additional $0.51 per share.

Taking all the above factors into consideration, the company now forecasts full year 2010 fully diluted earnings per share to be in the range of $2.48 to $2.52, which is above June guidance of $2.25 to $2.35 and 2009 earnings of $2.24 per share.

Fourth Quarter 2010

Fourth quarter constant dollar net revenue yields are expected to increase 2.5 to 3.5 percent (down 1 to 2 percent on a current dollar basis) compared to the prior year. Net cruise costs excluding fuel per ALBD for the fourth quarter are expected to be 1 to 2 percent lower on a constant dollar basis (down 5 to 6 percent on a current dollar basis). For the fourth quarter, unfavorable currency exchange rates and fuel costs are expected to impact earnings by $60 million compared to the prior year, costing an additional $0.07 per share.

Based on the above factors and using current fuel prices and currency exchange rates, the company expects earnings for the fourth quarter 2010 to be in the range of $0.32 to $0.36 per share, compared to $0.24 per share in 2009.

During the fourth quarter Cunard Line’s 2,092-passenger Queen Elizabeth will be christened by Her Majesty Queen Elizabeth II in a much anticipated ceremony in Southampton, England. This will be the sixth ship to be delivered this year furthering the company’s strategy to expand its global presence.

NOTES TO NON-GAAP FINANCIAL MEASURES

(a) We use net cruise revenues per ALBD (“net revenue yields”) and net cruise costs per ALBD as significant non-GAAP financial measures of our cruise segment financial performance. These measures enable us to separate the impact of predictable capacity changes from the more unpredictable rate changes that affect our business. We believe these non-GAAP measures provide a better gauge to measure our revenue and cost performance instead of the standard U.S. GAAP-based financial measures. There are no specific rules for determining our non-GAAP financial measures and, accordingly, it is possible that they may not be exactly comparable to the like-kind information presented by other cruise companies, which is a potential risk associated with using these measures to compare us to other cruise companies.

Net revenue yields are commonly used in the cruise industry to measure a company’s cruise segment revenue performance and for revenue management purposes. We use “net cruise revenues” rather than “gross cruise revenues” to calculate net revenue yields. We believe that net cruise revenues is a more meaningful measure in determining revenue yield than gross cruise revenues because it reflects the cruise revenues earned net of our most significant variable costs, which are travel agent commissions, cost of air transportation and certain other variable direct costs associated with onboard and other revenues. Substantially all of our remaining cruise costs are largely fixed, except for the impact of changing prices, once our ship capacity levels have been determined.

Net cruise costs per ALBD is the most significant measure we use to monitor our ability to control our cruise segment costs rather than gross cruise costs per ALBD. We exclude the same variable costs that are included in the calculation of net cruise revenues to calculate net cruise costs to avoid duplicating these variable costs in these two non-GAAP financial measures.

We have not provided estimates of future gross revenue yields or future gross cruise costs per ALBD because the reconciliations of forecasted net cruise revenues to forecasted gross cruise revenues or forecasted net cruise costs to forecasted cruise operating expenses would require us to forecast, with reasonable accuracy, the amount of air and other transportation costs that our forecasted cruise passengers would elect to purchase from us (the “air/sea mix”). Since the forecasting of future air/sea mix involves several significant variables that are relatively difficult to forecast and the revenues from the sale of air and other transportation approximate the costs of providing that transportation, management focuses primarily on forecasts of net cruise revenues and costs rather than gross cruise revenues and costs. This does not impact, in any material respect, our ability to forecast our future results, as any variation in the air/sea mix has no material impact on our forecasted net cruise revenues or forecasted net cruise costs. As such, management does not believe that this reconciling information would be meaningful.

In addition, because a significant portion of our operations utilize the euro or sterling to measure their results and financial condition, the translation of those operations to our U.S. dollar reporting currency results in decreases in reported U.S. dollar revenues and expenses if the U.S. dollar strengthens against these foreign currencies and increases in reported U.S. dollar revenues and expenses if the U.S. dollar weakens against these foreign currencies. Accordingly, we also monitor and report our two non-GAAP financial measures assuming the 2010 periods’ currency exchange rates have remained constant with the 2009 periods’ rates, or on a “constant dollar basis,” in order to remove the impact of changes in exchange rates on our non-U.S. dollar cruise operations. We believe that this is a useful measure since it facilitates a comparative view of the growth of our business in a fluctuating currency exchange rate environment.

On a constant dollar basis, net cruise revenues and net cruise costs would be $3.7 billion and $1.9 billion for the three months ended August 31, 2010 and $8.7 billion and $5.6 billion for the nine months ended August 31, 2010, respectively. On a constant dollar basis, gross cruise revenues and gross cruise costs would be $4.4 billion and $2.6 billion for the three months ended August 31, 2010 and $10.5 billion and $7.4 billion for the nine months ended August 31, 2010, respectively.

(b) ALBDs is a standard measure of passenger capacity for the period, which we use to perform rate and capacity variance analyses to determine the main non-capacity driven factors that cause our cruise revenues and expenses to vary. ALBDs assume that each cabin we offer for sale accommodates two passengers and is computed by multiplying passenger capacity by revenue-producing ship operating days in the period.
