McDonald's Q3 2026 global comparable sales face pressure from U.S. softness that offset international gains in the prior quarter. U.S. comparable sales grew just 0.8% in Q2 amid execution shortfalls on value-menu promotions and traffic declines, while global comps reached 1.3% and international operated markets advanced 1.5%. Management expects international segments to accelerate, supported by a new $8.5 billion franchisee support plan and productivity targets announced in mid-October that aim to lift margins and market share. With earnings scheduled for November 4, trader consensus reflected in the 61.5% implied probability on 1-2% growth prices in modest sequential improvement but limited upside from lingering domestic challenges.
