Kohl's and other retailers are facing a challenging environment for growth as consumers tame discretional spending. The company said its same-store sales fell less than a percent in August as apparel demand slowed.

Same-store sales, or sales at stores open at least a year, is a key indicator of retailer performance since it measures growth at existing stores rather than newly opened ones.

The indicator's August "softness and heavy inventory levels in the context of a tougher consumer backdrop make it challenging for us to get more positive on the stock," said JPMorgan analyst Charles Grom in a note Monday.

Kohl's Chairman and Chief Executive Larry Montgomery said the new top-level executives, who were all chosen internally, "possess an extensive understanding of our business and are instrumental to our continued success."

Kohl's shares rose 4 cents to $53.19 in after-hours trading.
