May 13 (Reuters) - Under Armour ( UAA ) on Tuesday

posted a smaller-than-expected drop in fourth-quarter revenue,

helped by the sportswear maker's efforts to streamline its

product lines that drove improved sales.

The Maryland-based retailer has been attempting to reset

its business to reverse last year's sales slump by focusing on

full-price sale of its products, lower promotions, inventory and

workforce reductions.

The company's quarterly revenue fell 11% to $1.18

billion from a year ago, compared with analysts' average

estimate of a 12.4% drop to $1.17 billion, according to data

compiled by LSEG.

The company, however expects revenue for the current quarter

to decline 4% to 5%, compared with analysts' expectations of a

1.9% fall, according to data compiled by LSEG.

It also refrained from providing an annual forecast, citing

uncertainty surrounding trade policies and the macroeconomic

environment, including potential demand-related and cost impacts

from tariffs.
