Starbucks reported first-quarter revenue of $9.4 billion, up 8% year-over-year but missing estimates of $9.6 billion. Adjusted EPS was $0.90, also below expectations. US same-store sales grew 5% year-over-year versus the estimated 5.73%, and foot traffic rose only 1%, while check size went up 4%. Starbucks lowered its FY2024 total revenue growth guidance to 7 to 10% from 10 to 12% previously. Starbucks aims to boost U.S. foot traffic further by launching three new flavor lines targeting Gen Z and introducing new drinks for Valentine's Day.
