• Starbucks raised its fiscal 2021 outlook for earnings and revenue.
• The company topped Wall Street's earnings estimates, but its quarterly revenue fell short of expectations.
• U.S. same-store sales rose 9%, returning to pre-pandemic levels.

Starbucks on Tuesday reported mixed quarterly results and raised its full-year forecast for earnings and revenue.

While the company's earnings topped Wall Street's expectations, its revenue missed estimates, dragged down by some international markets' slower recovery.

Shares of the company dropped nearly 2% in extended trading.

Here's what the company reported compared with what Wall Street was expecting, based on a survey of analysts by Refinitiv:

• Earnings per share: 62 cents adjusted vs. 53 cents expected
• Revenue: $6.7 billion vs. $6.8 billion expected

Starbucks reported fiscal second-quarter net income of $659.4 million, or 56 cents per share, up from $328.4 million, or 28 cents per share, a year earlier.

Excluding items, the coffee chain earned 62 cents per share, topping the 53 cents per share expected by analysts surveyed by Refinitiv.

Net sales rose 11% to $6.7 billion, missing expectations of $6.8 billion. Global same-store sales grew by 15% as the company lapped a decline of 10% from the year-ago period.

U.S. same-store sales rose 9%, returning to pre-pandemic levels. A year ago, same-store sales in Starbucks' home market fell 3% as lockdowns were implemented across the United States. This quarter, customers bought larger and more expensive coffees and added food to their orders, sending the average ticket up 21%. Traffic, however, is still down by 10%. Executives said they are seeing some labor shortages in certain markets, but it's not a widespread issue.

Outside the U.S., same-store sales rose 35% despite many European countries extending lockdowns.

In China, Starbucks' second-largest market, same-store sales surged 91% as it faced comparisons with last year's 50% plummet during the same period. Transactions in China soared 93% in the quarter, but average ticket fell 1%. Starbucks executives said the company hadn't anticipated restrictions related to the pandemic in China, including discouraging nonessential travel even during the Chinese New Year holiday.

CEO Kevin Johnson told analysts that vaccination progress is key to predicting a market's recovery. Starbucks is using its artificial intelligence technology to predict how inoculation rates will impact international sales growth.

The company opened five net new cafes during the quarter. That includes the impact of closing roughly 300 locations in the U.S. and Canada, which it previously announced in June as part of a broader strategy to update its restaurant footprint.

For all of fiscal 2021, Starbucks now expects to earn $2.65 to $2.75 per share, up from its prior range of $2.42 to $2.62 per share. It's expecting earnings on an adjusted basis of $2.90 to $3 per share, up from its previous outlook of $2.70 to $2.90 per share. Analysts were expecting earnings per share of $2.85 for the fiscal year.

The company also raised its full-year outlook for revenue to a range of $28.5 billion to $29.3 billion, up from a prior range of $28 billion to $29 billion. Wall Street was forecasting revenue of $28.6 billion. Fiscal 2021 includes a 53rd week, which Starbucks expects will add about $500 million in revenue.
