Under Armour suffered an 11 percent drop in its share value after warning investors that its sales are likely to be flat in North America in 2019, growing overall by between 3 and 4 percent against a consensus estimate of 5 percent. On the other hand, the gross margin for this year is now expected to be flat instead of a previous forecast that it will be flat or down slightly. Revising its longer-term targets, UA said its sales should grow between 2020 and 2022 at a compound annual rate in the low single digits in North America, in the mid-teens in the EMEA region, at a double-digit rate in Latin America and in the mid-20s in Asia-Pacific.
