UniSuper hopes to capitalise on soaring demand for digital data after spending $1 billion to take a 5 per cent stake in Dusseldorf-headquartered telecommunications infrastructure group Vantage Towers.

The $115 billion superannuation group’s head of private markets, Sandra Lee, told The Australian Financial Review that UniSuper had secured the investment in Vantage Towers – which builds and operates towers that transmit voice and data signals – at a fixed price through a relationship with US private equity group KKR.
