"Over the long-term I think a strong dollar is a good thing, as it draws investment into the U.S." he said in an interview. "From an earnings perspective short-term, it hits us, but I look at it as banked earnings growth for the future," he said.
While Doyle wouldn't say if second-quarter revenue will top first-quarter's impressive 10.6% increase, he said the company has plenty of momentum globally. "First-quarter was incredibly strong, up 14.5 percent on our domestic same-store sales," he said, referring to a key industry metric.
The company has also been working to integrate its "pizza theatre" concept into its restaurants, which allows customers to watch as their pizza is prepared, among other features.
But Doyle said that goal doesn't trump opening new locations. "We need to do both," he said. "We need to be growing new locations and reimaging the ones we have. Pizza Theatre is about opening up our kitchens and letting customers see the quality of the ingredients."
He said all stores will be reimaged by the end of 2017 and some 25% have been completed so far. The company's store count as of March stands at 11,739.
Domino's Pizza is also taking advantage of the digital world, as half its sales stem from digital platforms.
"If you look at the pizza category overall in the U.S., only 15-17% of sales are digital," he said. "With us at 50%, I think you will continue to see the category shift that way, and hopefully we can take more of the share of that growth."
Restaurant chain Panera Bread (PNRA) is also in the process of reworking stores to become more technologically advanced. The company wants to take advantage of the growing digital trend by integrating iPad kiosks into stores, enabling customers to place orders.
Shares of Domino's Pizza have returned 15% since the start of the year.
