“In our first year as R.B.I., we set the foundation for long-term growth at Tim Hortons, while building on the momentum at Burger King,” said Daniel Schwartz, chief executive officer of Restaurant Brands International, during a Feb. 16 earnings call with financial analysts. “We continue to be focused on driving top-line growth and finding the right partners to bring great restaurants to our guests all around the world.”

For the fiscal year ended Dec. 31, 2015, the company had net income of $511.7 million, equal to 51c per share on the common stock, up 17% from net income on a pro forma basis of $437.1 million for the prior year. Revenues for the year totaled $4,052.2 million, down 3.5% from pro forma revenues of $4,200.3 million, due to the unfavorable impact of foreign currency translation. The pro forma amounts reflect consolidated financial information as if the merger between Tim Hortons and Burger King Worldwide had occurred at the beginning of 2014.

Net income for the fourth quarter advanced to $184.5 million, or 25c per share, up 242% from pro forma net income of $54 million for the year-ago period. Revenues declined 3.3% to $1,057 million from pro forma revenues of $1,092.7 million.

Comparable sales at Burger King increased 5.4% for the year and 3.9% for the quarter on a constant currency basis, behind successful new product launches and promotions, including new Chicken Fries varieties and the A.1. Halloween Whopper sandwich.

Burger King plans to launch its new flame-grilled hot dogs on Feb. 23.

“Our newest launch, grilled (hot) dogs, builds upon the momentum of our successful strategy of launching fewer and more impactful products,” Mr. Schwartz said. “Grilled dogs are a flame grilled take on one of America’s favorite foods, the hot dog, and with the launch of grilled dogs, we are now going to be serving hot dogs at more locations than any other restaurant chain in the United States.”

At Tim Hortons, comparable sales increased 5.6% for the year and 6.3% for the quarter in constant currency, driven by continued strength in beverages and new menu introductions such as Nutella pockets and grilled wraps.

Tim Hortons' sales growth was fueled by new menu item introductions, like Nutella pastry pockets.

“We had a truly historic year at Tim Hortons, with a number of successful product launches, accelerated restaurant development and strong financial results,” Mr. Schwartz said. “Our marketing success was due to a balanced strategy of defending our leadership in coffee while expanding our presence in different day parts with successful new product launches.”
