Domino's Pizza Inc. (DPZ) said Tuesday that its profit grew 36 percent in the first quarter, boosted by improved distribution business and sharp gains in sales both in the United States and abroad.

Revenue totaled $369.7 million, up 16 percent from $318.8 million a year earlier. Domino's (search) said results got a lift from its domestic food-distribution business, where revenue swelled 18 percent to $201.8 billion.

Meanwhile, sales from U.S. company-owned locations rose 12 percent to $98.2 million, while sales at franchised restaurants increased 13 percent to $39.2 million and international sales jumped 20 percent to $30.4 million.
