Klein, former chief financial officer of Microsoft, joined WME in December to help the agency navigate its $2.4 billion acquisition of sports and marketing powerhouse IMG.
Klein’s departure has stirred up chatter in tenpercentery and finance circles about WME facing challenges in absorbing its much larger rival. WME and its equity partner, Silver Lake, laid out a premium price of $2.4 billion to acquire IMG in a bidding process held last December.
Sources close to the situation said there were personal considerations behind Klein’s decision to step down, among other issues.
Klein’s hire was seen as a sign that the enlarged WME was preparing to be much more active in the Wall Street and financial community. There are persistent rumors that WME will at some point mount an IPO. Klein had spent 11 years with Microsoft before departing last year.
