SEATTLE — An alleged war on Christmas by Starbucks apparently didn’t dampen the chain’s holiday sales, but its outlook going forward fell short of Wall Street expectations.

The Seattle-based company said Thursday sales rose 9 percent in its flagship U.S. market during the final three months of the year. The jump was the result of an increase in customer visits as well as spending on items like breakfast sandwiches.

The higher sales came despite an online backlash from some corners when Starbucks unveiled its minimalist red cups for the holidays bearing only its logo. That was a change from past years, when the company’s holiday cups were decorated with reindeer, snowflakes and Christmas ornaments.

Its performance overseas was weaker. In Western Europe, the company said it noticed a “dramatic decline in consumer and tourist activity” after the terrorist attacks in Paris in November. Sales for the unit including Europe, the Middle East and Africa rose 1 percent at established locations, down from growth of 5 percent in the prior quarter.
