Sports Direct International (SDI) is buying additional shares in Debenhams, the British department store chain, paying 43 percent more than they were worth last Friday, according to The Financial Times. The acquisition is said to be based on options contracts signed through Goldman Sachs in 2015, which will force SDI to acquire a 10.5 percent stake in Debenhams at a set price in October and November. SDI said it has appointed a former equity research analyst, Liam Rowley, to conduct a thorough review of all its current strategic stakes. SDI has opened concessions in nine Debenhams stores, but four of them are going to be closed by next spring, says the FT.
