(Reuters) - Domino's Pizza Inc (>> Domino's Pizza, Inc.) on Tuesday reported a quarterly profit that topped Wall Street's estimates, boosted by strong results overseas and its home market of the United States, where rival Pizza Hut is struggling.

The second-largest U.S. pizza chain by store count said net income rose to $35.6 million, or 63 cents per share, in the third quarter ended Sept. 7 from $30.6 million, or 53 cents per share, a year earlier.

Analysts on average had expected a profit of 61 cents per share, according to Thomson Reuters I/B/E/S.

Revenue rose 10.5 percent to $446.6 million after sales at stores open at least one year at domestic and international shops increased more than expected.

Domino's rivals include Yum Brands Inc's (>> Yum! Brands, Inc.) Pizza Hut, Little Caesars Pizza and Papa John's International Inc (>> Papa John's Int'l, Inc.).

Domino's had 5,016 domestic outlets and 6,265 international stores at the end of the quarter.
