May 12 (Reuters) - Under Armour UAA.N forecast a drop in annual revenue on Tuesday, as the athletic apparel struggles with weak consumer spending and macroeconomic uncertainty in its key North American market.

The company expects revenue for its fiscal year 2027 to fall a low single-digit, compared with analysts' average expectation of a 1.6% rise to $5.05 billion, according to data compiled by LSEG.
