Dick’s Cuts Guidance as Foot Locker Turnaround Reverses

Shares of Dick’s Sporting Goods Inc (NYSE:DKS) sank by more than 28% Tuesday after management slashed full-year profit expectations, driven largely by a reversal at Foot Locker, the sneaker chain Dick’s bought for $2.5 billion less than 12 months earlier.

Foot Locker posted a $31.9 million segment loss for the quarter, a stark reversal from the $110 million to $150 million in annual profit executives had guided toward just three months prior, and comparable sales at the chain fell 3.6% after rising 0.6% the prior quarter. Executive Chairman Ed Stack cited a more promotional retail landscape along with Foot Locker’s heavy exposure to sneaker drops, throwback releases and older shoe models as the main factors behind the shortfall.
