Regarding the necessity to add value to businesses, we consider private equity firms to have a similar role as the centre of an unrelated diversified multi-business firm, and analyse survey data on 267 portfolio companies using partial least squares structural equation modelling. The results show that corporate centres can create value through vertical intervention in single business units, by reducing agency costs through governance mechanisms as part of their administrative function and, interestingly, by also providing businesses access to strategic resources during the course of their entrepreneurial function. In particular, the provision of intangible resources, i.e., the knowledge and networks of the corporate centre, shows to have a value creating effect on business units.
