NEW YORK — Starbucks reported a 23 percent increase in its fourth-quarter profit Thursday, thanks to rising sales at its coffee shops and benefiting from an extra week in the period.

The results beat Wall Street expectations, and Starbucks also raised its dividend.

Seattle-based Starbucks said its fourth-quarter sales rose 5 percent at established stores in the Americas, which includes the U.S., its biggest market. That was above the 4.9 percent rise analysts expected. Global sales rose 4 percent at established stores, which was below the 4.9 percent increase analysts expected. Sales fell 1 percent at established stores in Europe, the Middle East and Africa.
