Listed US buyout major KKR is looking to gain control of German market research business after picking up a minority stake.
The firm has bought 14.1 per cent of GFK according to regulatory filings, and is looking to raise that to more than 75 per cent in collaboration with current majority shareholder GFK Verein.
That process is potentially under threat from fellow GFK stakeholder Michael Dell, who currently owns about 10 per cent of the business.
GfK currently employs more than 13,000 market research experts according to its website, and works in areas including consumer goods analysis and television audience ratings.
Last month KKR agreed to buy Hitachi power tools unit Hitachi Koki Co for about $1.3bn.
Hitachi Koki is a global supplier of high performance, high quality power tools and life science equipment.
