Christian Haub, head of Obi's parent company Tengelmann, may be planning an IPO for the DIY store operator Obi and the clothing chain Kik. This is according to a report in the Westdeutsche Allgemeine Zeitung (WAZ). The reason is "disappointment" with his brother Georg, with whom he has been at loggerheads for some time. However, the IPO is only one of several options; institutional investors could also come into play.
