Starbucks’ revenue fell one percent in the April-June period as customer traffic weakened in the US and China.

But the Seattle coffee giant expressed optimism Tuesday that successful new products and improvements in efficiency — including faster drive-thru service and better equipment — will help turn things around in its next fiscal year, which begins later this fall.

“We are focused on what we can control in a consumer environment that can best be described as ‘complex,’” Starbucks CEO Laxman Narasimhan said during a conference call with investors.

Narasimhan said consumers in many markets have gotten more cautious with their spending and are staying home. Starbucks’ comments mirrored those at McDonald’s, which said earlier this week that its same-store sales fell 1 percent in the April-June period.

Starbucks’ same-store sales — or sales at locations open at least a year — fell three percent. That was slightly higher than the 2.7 percent drop Wall Street had expected, according to analysts polled by FactSet.

In China, where Starbucks is feeling pressure from lower-priced rivals, same-store sales plunged 14 percent. Chinese customers visited less often and spent less per visit, Starbucks said.

Narasimhan said Starbucks believes it still has immense opportunity in China, which is its second-largest market with 6,500 stores. But he said the company is in the early stages of exploring a strategic partnership or joint venture in China that could help it accelerate its growth. Such a partnership could also lessen Starbucks’ exposure to the market’s volatility.

“What we want to be sure of is that we are further strengthening our advantage in this market because the long-term opportunity for us is significant,” he said.

In the US, same-store sales fell two percent. Starbucks said higher spending per visit helped offset a six percent slowdown in traffic.

Narasimhan said there were some bright spots in the US. The company’s new Summer-Berry Refresher, which has boba-like raspberry pearls, saw the highest first-week sales for a new product in the company’s history. Starbucks also noted a seven percent increase in US loyalty members during the quarter.

But Narasimhan said the company has work to do to increase afternoon sales and improve its supply chain. The Summer-Berry Refresher was so popular the company ran out of ingredients and had to pull back on marketing, he said. Starbucks has also trouble keeping its food items in stock.

Narasimhan said Starbucks also still faces boycotts of its stores in the Middle East, Southeast Asia, and parts of Europe for its perceived support of Israel in the war in Gaza.

Starbucks reported revenue of $9.1 billion for its fiscal third quarter. That was lower than the $9.2 billion Wall Street anticipated, according to analysts polled by FactSet.

Net income fell 7.6 percent to $1.05 billion, or 93 cents per share. That was in line with analysts’ forecasts.

Narasimhan confirmed recent reports that activist investor Elliott Investment Management has taken a stake in the company.

“Our conversations to date have been constructive,” he said.

Starbucks shares rose three percent in after-hours trading Tuesday. The stock has fallen 25 percent in the last 12 months.
