The international arm of Domino’s Pizza reported a 68% rise in first quarter profit to $23.8m (£16.02m), up from $14.1m a year earlier.
The company saw international same store sales rise 6.6% and US same store sales increased 1%.
The pizza chain said that the rise in net income has been primarily as a result of it repurchasing a portion of debt at deep discounts. It had around $1.7bn in total debt at the end of the quarter.
It said that growth across its international business had been offset by the negative effect of foreign exchange.
US franchised stores saw sales rise 1.1%, while US company-owned store sales fell 0.1%, as the company said its domestic franchise system was starting to regain some positive momentum.
David Brandon, Domino's chairman and chief executive, said: "I am very satisfied with our operational performance during the quarter, and I am cautiously optimistic about our first half outlook.
“We are re-establishing our industry leadership position in the areas of product and technology innovation, marketing and retail execution -- and our domestic franchisees outperformed our team US stores in same store sales for the first time in many quarters.”
The announcement follows Domino’s Pizza UK and Ireland division reporting a 9.3% increase in first quarter sales at its mature stores.
