The group – which saw founder and Newcastle United owner Mike Ashley step in to replace Dave Forsey as chief executive last month – said Matt Pearson was leaving at the end of the year to take a role with another firm.
Sports Direct said Herbert Monteith, an “experienced and long-standing” member of its finance team, has been appointed as interim head of finance, which is not a board position.
The moves comes after the retailer warned last week over a profits hit from the tumbling pound, which sparked concerns that Pearson was still employed on an acting basis and that the group had not moved to appoint a permanent finance chief.
Sports Direct has been embroiled in controversy in recent months, with Ashley hauled before MPs to be grilled over working conditions, the company hosting a tumultuous “open day” at its headquarters and Forsey quitting as its chief executive.
Ashley said today: “Matt has been a valued member of the Sports Direct family for over nine years and he will be a loss to the company. I wish him all the best for the future and would like to thank him for his time at Sports Direct.”
