Starbucks earnings hit Wall Street's target in the latest quarter, but shares fell 3.5 percent in aftermarket trading on Thursday after the company posted its lowest same-store sales growth since 2009.
The coffee giant said same-store sales grew 3 percent during the fiscal first quarter, lower than analyst's expectations of 3.8 percent.
Same-store sales in the Americas rose 3 percent for the quarter, which was shy of the 3.9 percent estimate. President Kevin Johnson noted that same-store sales growth was hindered, in part, by growing mobile pay and ordering.
The soon-to-be CEO said during an earnings conference call that the bump in mobile ordering had caused many stores to experience congestion at the hand-off counter. Despite lines at the register being short, incoming customers would see the crowd and leave without making a purchase.
"We are now laser-focused on fixing this problem, but the nature of it, too much demand, is an operational challenge we have solved before and I can assure you we will solve again," CEO Howard Schultz said on a conference call.
The story was brighter at the company's China/Asia Pacific segment, where same-store sales rose 5 percent during the quarter, outpacing analyst expectations of 2.9 percent.
Starbucks' Europe, the Middle East and Africa segment saw same-store sales fall 1 percent during the quarter. Analysts expected the segment to grow 1.7 percent.
