Nike's shares jumped at the opening bell Friday after the company said it's shifting some production away from China. But it also warned that tariffs imposed by the Trump administration will cost it about $1 billion before it makes internal changes, which include "surgical" price increases in the U.S. starting this fall.

Nike is not the first retail company to warn of price hikes when students are heading back to school. Walmart said last month that that its customers will start to see higher prices this month and next when the back-to-school shopping season goes into high gear.

Walmart also cited higher costs from tariffs.

Nike is shifting production to avert looming tariffs in China. Production in China represents about 16% of the footwear that Nike imports into the U.S., Chief Financial Officer Matthew Friend said during a conference call late Thursday. That production will be cut to the high-single-digit range by the end of fiscal 2026 as Nike shifts production elsewhere, he said.

President Donald Trump and his Commerce Secretary Howard Lutnick said late Thursday that the U.S. and China have signed an agreement on trade, but provided no details.

Nike, Adidas, Under Armour and Puma were among 76 companies that signed on to a letter in April addressed to Trump, asking for a footwear exemption from reciprocal tariffs. The letter warned tariffs would "become a major impact at the cash register for every family."

Nike said that it will begin to implement "surgical" price increases as part of its regular approach to seasonal planning, beginning this fall, Friend said.

The potential for higher prices from Trump's tariffs have raised alarms for families, notably those who already spend a good chunk of money on equipment needed to participate in sports.

Also on Thursday, Nike reported a quarterly profit of $211 million, or 14 cents per share. Revenue totaled $11.1 billion. Both edged out Wall Street projections.

Nike is already facing a pullback in spending by Americans, who have grown anxious about the direction of the U.S. economy. While it's still the most significant brand in sportswear, a "boredom factor" seems to have settled over the Nike brand, wrote Neil Saunders, Managing Director of GlobalData.

"In markets like China, where overall market growth has slowed a little, Nike is also on the back foot for similar reasons," Saunders wrote. "We also see some anti-US brand sentiment creeping in, which is unhelpful and difficult to resolve."

Shares of Nike, based in Beaverton, Oregon, jumped 15% at the opening bell Friday.
