Under Armour's stock experienced a sharp decline of 17.09% during intraday trading on Tuesday, reflecting a significant sell-off following the release of its latest financial results.

The sportswear brand reported a fiscal fourth-quarter adjusted loss per share of $0.03, which missed analyst expectations. More critically, the company issued a subdued outlook for its fiscal 2027, projecting adjusted earnings per share in the range of $0.08 to $0.12, well below the average analyst estimate of $0.23. Under Armour also expects annual revenue to decline slightly, contrasting with market expectations for growth.

The disappointing guidance and earnings miss highlight ongoing challenges, including weak consumer spending in the key North American market, higher costs from tariffs and product-price inflation, and increased expenses related to the company's extended restructuring plan.
