CARNIVAL CORPORATION & PLC REPORTS RECORD SECOND QUARTER EARNINGS

AND ADDITIONAL $1 BILLION SHARE REPURCHASE AUTHORIZATION

MIAMI (June 28, 2016) – Carnival Corporation & plc (NYSE/LSE: CCL; NYSE: CUK) announced adjusted net income of $370 million, or $0.49 diluted EPS for the second quarter of 2016 compared to adjusted net income for the second quarter of 2015 of $193 million, or $0.25 diluted EPS. For the second quarter of 2016, U.S. GAAP net income, which included unrealized gains on fuel derivatives of $242 million and $7 million of other expenses, was $605 million, or $0.80 diluted EPS. For the second quarter of 2015, U.S. GAAP net income was $222 million, or $0.29 diluted EPS. Revenues for the second quarter of 2016 were $3.7 billion compared to $3.6 billion for the prior year.

Carnival Corporation & plc President and CEO Arnold Donald stated, “Our strong second quarter demonstrates continued momentum as we again achieved a near doubling of adjusted earnings per share. Our ongoing effort to drive demand for our brands in excess of our measured capacity growth has led to increased revenues and helped maintain the mid-point of our full year earnings guidance despite the recent currency movements and rises in fuel prices that combined represent a negative $0.17 per share.”

Donald also noted several major milestones that will contribute to the future of the company including the re-mastering of Queen Mary 2, the opening of Holland America’s Denali square complex in Alaska and the introduction of AIDA Cruises’AIDAprima, Holland America Line’s Koningsdam, and Carnival Cruise Line’s Carnival Vista. In addition, building on a legacy of pioneering achievements, Carnival Corporation became the first cruise company to begin operating voyages from the US to Cuba in more than four decades through its Fathom brand - a historic moment that captured worldwide media coverage.

Key metrics for the second quarter 2016 compared to the prior year were as follows:

2016 Outlook

At this time, cumulative advance bookings for the remainder of the year are well ahead of the prior year at slightly higher prices. Since March, bookings for the remainder of the year are at higher prices with volumes running lower than last year because there is less inventory remaining for sale than at this time in 2015.

The company expects full year 2016 net revenue yields on a constant currency basis to be up approximately 3.5 percent versus the prior year, compared to March guidance of approximately 3 percent. The company now expects full year 2016 net cruise costs excluding fuel per ALBD to be up approximately 1.5 percent compared to the prior year on a constant currency basis, better than March guidance of approximately 2.0 percent. Changes in fuel prices (including fuel derivatives) and currency exchange rates are expected to reduce full year earnings by $0.17 per share compared to March guidance.

Taking the above factors into consideration, the company expects full year 2016 adjusted earnings per share guidance to be in the range of $3.25 to $3.35, compared to March guidance of $3.20 to $3.40 and 2015 adjusted earnings of $2.70 per share.

Donald noted, “This is shaping up to be another strong year for our company as we expect over 20 percent earnings growth and are approaching a nine percent return on invested capital. We have accelerated progress toward our stated goal of achieving the double digit return threshold and have accelerated distributions to shareholders. We recently raised our dividend by 17 percent to over $1 billion per year. Since October, we have repurchased nearly $1.9 billion in shares under our stock repurchase program. Yesterday, our Board of Directors approved our third $1 billion share repurchase authorization demonstrating confidence in our outlook and reinforcing our commitment to return value to shareholders.”

Third Quarter 2016 Outlook

Third quarter constant currency net revenue yields are expected to be up 2 to 3 percent compared to the prior year. Net cruise costs excluding fuel per ALBD for the third quarter are expected to be 6 to 7 percent higher on a constant currency basis compared to the prior year driven by the timing of advertising expense and the re-mastering of Queen Mary 2 in dry-dock. Changes in fuel prices (including fuel derivatives) and currency exchange rates are expected to increase third quarter earnings by $0.01 per share compared to the prior year.

Based on the above factors, the company expects adjusted earnings for the third quarter 2016 to be in the range of $1.83 to $1.87 per share versus 2015 adjusted earnings of $1.75 per share.

Notes to Non-GAAP Financial Measures

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 and other transportation, certain other costs that are directly associated with onboard and other revenues and credit and debit card fees. Substantially all of our remaining cruise costs are largely fixed, except for the impact of changing prices and food expenses, once our ship capacity levels have been determined.

Net passenger ticket revenues reflect gross passenger ticket revenues, net of commissions, transportation and other costs. Net onboard and other revenues reflect gross onboard and other revenues, net of onboard and other cruise costs. Net passenger ticket revenue yields and net onboard and other revenue yields are computed by dividing net passenger ticket revenues and net onboard and other revenues by ALBDs.

Net cruise costs per ALBD and net cruise costs excluding fuel per ALBD are the most significant measures we use to monitor our ability to control our cruise segments’ 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 with and without fuel to avoid duplicating these variable costs in our non-GAAP financial measures. In addition, we exclude gains and losses on ship sales and ship impairments, net and restructuring and other expenses from our calculation of net cruise costs with and without fuel as they are not considered part of our core operating business.

We have not provided a reconciliation of forecasted gross cruise revenues to forecasted net cruise revenues or forecasted gross cruise costs to forecasted net cruise costs because it would be too difficult to prepare reliable U.S. GAAP forecasts of gross cruise revenues and gross cruise costs without unreasonable effort.

In addition, our Europe, Australia & Asia (“EAA”) segment and Cruise Support segment operations utilize the euro, sterling and Australian dollar as their functional currencies to measure their results and financial condition. This subjects us to foreign currency translational risk. All of our North America, EAA and Cruise Support segments’ operations also have revenues and expenses that are in a currency other than their functional currency. This subjects us to foreign currency transactional risk.

CARNIVAL CORPORATION & PLC

NON-GAAP FINANCIAL MEASURES (CONTINUED)

We report non-GAAP financial measures on a “constant dollar” and “constant currency” basis assuming the 2016 period currency exchange rates have remained constant with the 2015 period rates. These metrics facilitate a comparative view for the changes in our business in an environment with fluctuating exchange rates.

Constant dollar reporting is a Non-GAAP financial measure that removes only the impact of changes in exchange rates on the translation of our EAA segment and Cruise Support segment operations.

Constant currency reporting is a Non-GAAP financial measure that removes the impact of changes in exchange rates on the translation of our EAA segment and Cruise Support segment operations (as in constant dollar) plus the transactional impact of changes in exchange rates from revenues and expenses that are denominated in a currency other than the functional currency for our North America, EAA and Cruise Support segments.

Examples:

While we forecast realized gains and losses on fuel derivatives by applying current Brent prices to the derivatives that settle in the forecast period, we do not forecast the impact of unrealized gains and losses on fuel derivatives because we do not believe they are an indication of our future earnings performance. Accordingly, our earnings guidance is presented on an adjusted basis only.
