(Reuters) -Nike ( NKE ) said it would cut its reliance on production in China for the U.S. market to mitigate the impact from U.S. tariffs on imports, and forecast a smaller-than-expected drop in first-quarter revenue, sending its shares up 11% in extended trading.

U.S. President Donald Trump's sweeping tariffs on imports from key trading partners could add around $1 billion to Nike's ( NKE ) costs, company executives said on a post-earnings call after the sportswear giant topped estimates for fourth-quarter results.

China, subject to the biggest tariff increases imposed by Trump, accounts for about 16% of the shoes Nike ( NKE ) imports into the United States, Chief Financial Officer Matthew Friend said.

But the company aims to cut the figure to a "high single-digit percentage range" by the end of May 2026 as it reallocates China production to other countries.

Consumer goods is one of the most affected areas by the tariff dispute between the world's two largest economies, but Nike's ( NKE ) executives said they were focused on cutting the financial pain.

Nike ( NKE ) will "evaluate" corporate cost reductions to deal with the tariff impact, Friend said. The company has already announced price increases for some products in the U.S.

"The tariff impact is significant. However, I expect others in the sportswear industry will also raise prices, so Nike ( NKE ) may not lose much share in the U.S.," said David Swartz, analyst at Morningstar Research.

RUNNING FINDS ITS FOOTING

CEO Elliott Hill's strategy to focus product innovation and marketing around sports is beginning to show some fruit with the running category returning to growth in the fourth quarter after several quarters of weakness.

Having lost share in the fast-growing running market, Nike ( NKE ) has invested heavily in running shoes such as Pegasus and Vomero, while scaling back production of sneakers such as the Air Force 1.

"Running has performed especially strongly for Nike ( NKE )," said Citi analyst Monique Pollard, adding that new running shoes and sportswear products are expected to offset the declines in Nike's ( NKE ) classic sneaker franchises at wholesale partner stores.

Marketing spending was up 15% year-on-year in the quarter. On Thursday, Nike ( NKE ) hosted an event in which its sponsored athlete Faith Kipyegon attempted to run a mile in under four minutes. 

Paced by other star athletes in the glitzy and live-streamed from a Paris stadium, Kipyegon fell short of the goal but set a new unofficial record.

Nike ( NKE ) forecast first-quarter revenue to fall in the mid-single digits, slightly better than analysts' expectations of a 7.3% drop, according to data compiled by LSEG.

Its fourth-quarter sales fell 12% to $11.10 billion, but still beat estimates of a 14.9% drop to $10.72 billion.

China continued to be a pain point, with executives saying a turnaround in the country will take time as Nike ( NKE ) contends with tougher economic conditions and competition.

The company's inventory was flat year-over-year at $7.5 billion as of May 31.
