MySale, which counts Sir Philip Green among its major shareholders as he holds 22 per cent through the Shelton Capital fund controlled by his wife, runs clearance sales for a wide range of fashion brands.
It had a rough start to life on the Alternative Investment Market after its shares were mistakenly listed at the wrong price on Monday which triggered a major sell-off. The business was valued at £340.5 million at its original 226p price.
Sports Direct, which has a growing international presence, said it is hopeful of working on areas including joint venture opportunities in Australasia and Asia.
Shares in MySale closed up 13.5p at 201p yesterday.
