Woolworths has said that each of its businesses must “stand on its own two feet”. For Big W, perhaps it could be cut off at the knees at some point. While an exit is hard to execute, in some form, we expect it may occur over the next 18 months. For the retail industry it will be highly disruptive given the floor space needs to generate more sales and gross profit. A mix of other retailers could generate as much as $2.3 billion, or 50%, more in sales than the prevailing level.  While in the short-run, it may benefit a retailer like Kmart, the medium-term risk is all major retailers with geographic overlap lose some sales, namely Coles, Woolworths, Kmart and Target.
