The Signa Retail Group, which already owns Karstadt Sports and a group of sports-specific e-tailers called Signa Sports United, has signed a letter of intent with the Otto Group to take over its SportScheck chain of sporting goods stores, according to Germany’s Lebensmittelzeitung. The report could not be confirmed, but as previously indicated, the acquisition would make sense because of SportScheck’s recent losses and its strong commitment to omni-channel solutions.
