Exhibit 99.1

Additional Information

March 26, 2010

On March 23, 2010, Carnival Corporation & plc reported net income of $175 million, or $0.22 diluted EPS, on revenues of $3.1 billion for its first quarter ended February 28, 2010. Net income for the first quarter of 2009 was $260 million, or $0.33 diluted EPS, on revenues of $2.9 billion. The 2010 first quarter included a $0.05 gain from the sale of P&O Cruises’ Artemis. In addition, higher fuel prices reduced earnings in the 2010 first quarter by $0.22 per share as compared to the prior year.

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

• On a constant dollar basis net revenue yields (net revenue per available lower berth day) decreased 2.3 percent for Q1 2010, which was better than our December guidance of down 3 to 4 percent. Net revenue yields in current dollars increased 1.0 percent due to favorable currency exchange rates. Gross revenue yields decreased 1.3 percent in current dollars driven by lower air transportation revenue.

• Excluding fuel and the gain on the sale of Artemis, net cruise cost per available lower berth day (“ALBD”) declined 4.5 percent in constant dollars, which was better than our December guidance of down 2 to 3 percent.

• Including fuel and the gain on the ship sale, net cruise costs per ALBD increased 3.5 percent on a constant dollar basis (increased 6.2 percent in current dollars). Gross cruise costs per ALBD increased 1.7 percent in current dollars.

• Fuel price increased 80 percent to $497 per metric ton for Q1 2010 from $276 per metric ton in Q1 2009 and was higher than the December guidance of $474 per metric ton.

During the first quarter of 2010 the company announced that the Board of Directors voted to resume its quarterly dividend at $0.10 per share and the company announced a memorandum of agreement with Italian shipbuilder Fincantieri for the construction of two 3,600-passenger ships for Princess Cruises. The 139,000-ton ships would be the largest in the Princess fleet and would enter service in 2013 and 2014. Also during the first quarter of 2010, the company successfully introduced two new ships, AIDAblu and Costa Deliziosa, for its European brands.

2010 Outlook

As of March 23, 2010, we said that we expected our earnings per share for the second quarter and full year of 2010 would be in the range of $0.26 to $0.30 and $2.25 to $2.35, respectively. Our guidance was based in part on the assumptions in the table below.

	Full Year 2010	Second Quarter 2010
Fuel price per metric ton	$507	$511
Currencies
Euro	$1.38 to €1	$1.38 to €1
Sterling	$1.54 to £1	$1.52 to £1

The above forward-looking statements involve risks and uncertainties. Various factors could cause our actual results to differ materially from those expressed above including, but not limited to, economic and business conditions, foreign currency exchange rates, fuel prices, adverse weather conditions, spread of contagious diseases, regulatory changes, geopolitical and other factors that could adversely impact our revenues, costs and expenses. You should read the following forward-looking statement together with the discussion of these and other risks under “Cautionary Note Concerning Factors That May Affect Future Results.”

“Stock Swap” Programs

We use the “Stock Swap” programs in situations where we can obtain an economic benefit because either Carnival Corporation common stock or Carnival plc ordinary shares are trading at a price that is at a premium or discount to the price of Carnival plc ordinary shares or Carnival Corporation common stock, as the case may be.

In the event Carnival Corporation common stock trades at a premium to Carnival plc ordinary shares, we may elect to issue and sell Carnival Corporation common stock through an “At The Market” equity offering (“ATM Offering”) with Merrill Lynch, Pierce, Fenner & Smith, Incorporated (“Merrill Lynch”) as sales agent, and use the sale proceeds to repurchase Carnival plc ordinary shares in the UK market on at least an equivalent basis, with the remaining net proceeds used for general corporate purposes. In the ATM Offering, Carnival Corporation may issue and sell up to 19.2 million of its common stock in the U.S. market, which shares are to be sold from time to time at prevailing market prices in ordinary brokers’ transactions by Merrill Lynch. Any sales of Carnival Corporation shares have been and will be registered under the Securities Act.

In the event Carnival Corporation common stock trades at a discount to Carnival plc ordinary shares, we may elect to sell existing ordinary shares of Carnival plc, with such sales made by Carnival Investments Limited, a subsidiary of Carnival Corporation, and with Merrill Lynch International (“MLI”) as sales agent, from time to time in “at the market” transactions, and use the sale proceeds to repurchase Carnival Corporation common stock in the U.S. market on at least an equivalent basis, with the remaining net proceeds used for general corporate purposes. In the offering, Carnival Investments Limited may sell up to 25.0 million Carnival plc ordinary shares in the UK market, which shares are to be sold from time to time at prevailing market prices in ordinary brokers’ transactions by MLI. Any sales of Carnival plc shares have been and will be registered under the Securities Act.

Under the “Stock Swap” program from December 1, 2009 through February 28, 2010, Carnival Investments Limited sold 1.8 million Carnival plc ordinary shares, at an average price of $35.68 per share for gross proceeds of $63 million and paid MLI and others fees of $471 thousand and $90 thousand, respectively, for total net proceeds of $62 million. Substantially all of the net proceeds of these sales were used to purchase 1.8 million shares of Carnival Corporation common stock. During the three months ended February 28, 2010, there was no Carnival Corporation common stock sold under the “Stock Swap” program.

The purchases of Carnival Corporation common stock during the three months ended February 28, 2010 pursuant to the “Stock Swap” program were as follows:

Period	Total Number of Carnival Corporation Common Stock Purchased	Average Price Paid per Share of Carnival Corporation Common Stock		Maximum Number of Carnival Corporation Common Stock That May Yet Be Purchased Under the Carnival Corporation Stock Swap Program
December 1, 2009 through December 31, 2009	275,000	$	32.23	18,925,000
January 1, 2010 through January 31, 2010				18,925,000
February 1, 2010 through February 28, 2010	1,485,000	$	33.66	17,440,000
Total	1,760,000	$	33.44

During the quarter ended February 28, 2010, there were no stock repurchases of Carnival Corporation common stock or Carnival plc ordinary shares under the general stock repurchase authorization and no repurchases of Carnival plc ordinary shares under the “Stock Swap” program repurchase authorization.

Authorized Share Capital

Pursuant to a resolution of its shareholders dated April 15, 2009 and in accordance with the Companies Act 2006, Carnival plc ceased to have an authorized share capital with effect from October 1, 2009. However, any future issuance of shares by Carnival plc will remain subject to shareholder approval and preemptive rights (or the disapplication thereof).

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 increases in reported U.S. dollar revenues and expenses if the U.S. dollar weakens against these foreign currencies, and decreases in reported U.S. dollar revenues and expenses if the U.S. dollar strengthens against these foreign currencies. Accordingly, we also monitor and report our two non-GAAP financial measures assuming the 2010 period currency exchange rates have remained constant with the 2009 period 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. In addition, our non-U.S. dollar cruise operations’ depreciation and net interest expense were impacted by the changes in exchange rates for the three months ended February 28, 2010, compared to the prior year’s comparable period.

(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.
