Shares of Dunkin' Brands Group (NASDAQ: DNKN) rose 6% on Thursday after the coffee and donut chain bested Wall Street's earnings estimates and boosted its full-year profit guidance.
Dunkin' Brands' revenue rose 1.7% year over year to $355.9 million. The gains were driven by new store openings and a 1.5% increase in comparable-store sales.
Comp sales rose as price increases and strong sales of premium espresso drinks helped to offset a decline in traffic. Tepid traffic trends have been a prevalent theme in the restaurant industry in recent years and a persistent challenge for Dunkin' Brands.
