Burger King Takes Bite Out of McDonald's Sales Growth

The fast food landscape has shifted in favor of Restaurant Brands International's (QSR) Burger King, which posted an impressive 8.5% increase in same-store sales in the U.S. during the second quarter of 2026.

This outpaces McDonald's (MCD), its competitor and former market leader, which saw a meager 0.8% growth in the same category.

Burger King's success is attributed to its turnaround strategy, which includes remodeling existing stores and promoting its signature sandwich, the Whopper.

The parent company of Burger King, Restaurant Brands International, reported a more than 12% climb in earnings per share for the second quarter of 2026.

In contrast, McDonald's has struggled to execute effectively, with restaurants attributing the poor performance to over-reliance on new rollouts that have negatively impacted customer satisfaction and slowed service.
