Carnival Corp. announced non-GAAP net income of $193 million, or $0.25 diluted EPS for the second quarter of 2015 compared to non-GAAP net income for the second quarter of 2014 of $73 million, or $0.09 diluted EPS.

For the second quarter of 2015, U.S. GAAP net income, which included unrealized gains on fuel derivatives of $34 million and $7 million of restructuring expenses, was $222 million, or $0.29 diluted EPS. For the second quarter of 2014, U.S. GAAP net income was $98 million, or $0.13 diluted EPS. Revenues for the second quarter of 2015 were $3.6 billion, in line with the prior year.

Carnival Corporation & plc President and CEO Arnold Donald noted “We more than doubled our second quarter earnings versus the comparable period a year ago and significantly exceeded our quarterly earnings guidance. Our initiatives to create demand and leverage our scale benefited both cruise ticket prices and onboard revenues contributing to 5% revenue yield improvement (constant currency) this quarter. While all of our North American brands enjoyed strong revenue yield improvement, our Carnival Cruise Line brand performed particularly well again this quarter. We thank our teams around the globe for their consistent delivery of exceptional guest experiences as well as our travel agent partners for their strong support, both of which are critical to our success.”

Significant milestones during the second quarter included the launch of “fathom”, the tenth brand in the Carnival Corporation family. Beginning in April 2016, “fathom” will introduce a new cruise category offering travelers authentic and meaningful experiences to targeted destinations, beginning with the Dominican Republic, to work alongside locals for transformational community impact. Additionally, Costa began year-round service from Shanghai on Costa Serena in April and announced the deployment of Costa Fortuna to China in 2016 bringing the total to four Costa ships dedicated to Chinese guests. Princess Cruises also announced that it will expand its presence in Asia with a new ship scheduled to enter service in mid-2017 to be based in China year-round and customdesigned specifically for Chinese guests. Already the industry leader in passenger cruise days home ported in China, these developments will further the company’s leading presence in this rapidly expanding market and attract new cruisers to the company’s brands. Also, earlier this month Carnival Corporation finalized a contract with Meyer Werft shipyard to build four next-generation ships that will feature the largest guest capacity in the world as well as the first cruise ships to be powered at sea by Liquefied Natural Gas, which is the world’s cleanest-burning fossil fuel.
