LONDON, April 9 (Reuters) - British sportswear retailer

JD Sports on Wednesday forecast little or no profit

growth this year, even before any potential impact from U.S.

tariffs, with the trading environment in its key markets

expected to be "volatile".

Shares in JD have lost over a third of their value so

far this year on worries about consumer spending amid a downturn

in demand for Nike ( NKE ) products, which account for about 45%

of JD's sales. With just under 40% of its sales made in the

U.S., the group is also exposed to newly imposed U.S. tariffs.

JD said the outcome of the tariffs "is uncertain".

"We are in regular dialogue with our brand partners but

it is too early to comment on the potential sector impact," it

said.

JD forecast a year to February 1 2025 profit before tax

and adjusting items in line with its guidance in January of 915

million to 935 million pounds ($1.17-$1.20 billion).

For the 2025/26 year it forecast an outcome in line with

analysts' current consensus expectation of 920 million pounds.

However, it flagged that its forecast excludes any

potential impact from changes to tariffs.
