The rollout of COVID-19 vaccines and new rounds of government stimulus lifted consumer confidence for discretionary spending this year, helping Under Armour post a 32% increase in quarterly revenue from North America.
Revenue from the company's international segment surged 58%.
Under Armour said it would spend more on marketing its brand, stores and website, to take advantage of recovering markets, including North America, China and Germany.
It expects marketing and incentive compensations to make up about three quarters of the increase in costs this year.
Still, the sportswear maker lifted its full-year adjusted earnings per share forecast to between 28 cents and 30 cents, from 12 cents to 14 cents.
It expects full-year revenue to rise by a high-teens percentage, compared with a previous outlook of a high single-digit percentage increase. The company forecast second-quarter revenue to rise about 70% after store closures hammered sales a year ago.
Under Armour, like rival Nike Inc, also flagged transportation and logistics problems caused by the COVID-19 pandemic.
Under Armour's shares fell 2.3% to $23.60 in choppy trading. Its stock has risen about 40% this year.
"There are still industry issues to look out for such as issues with ports. It's not that the consumer doesn't want the product but we're seeing issues with getting the product in store," said Jessica Ramirez, retail analyst at Jane Hali & Associates.
Under Armour's first-quarter net revenue rose to $1.26 billion, beating estimates of $1.13 billion, according to IBES data from Refinitiv.
The company earned 16 cents per share, on an adjusted basis, beating estimates of 3 cents per share.
