ANN ARBOR, MICH. – Third-quarter net income for Domino’s Pizza, Inc. increased 18% thanks to same-store sales growth, store count growth and a lower effective tax rate.

Domestic same-store sales grew 5.4% during the quarter versus the year-ago period. The international division had same-store sales growth of 5%. Ann Arbor-based Domino’s Pizza had global net store growth of 126 stores in the third quarter and had 10,566 stores total as of Sept. 8.
