Private investors will hold a 49 per cent stake in Nagad Ltd and the postal department the rest as the government looks to run the mobile financial service as a subsidiary, its top executive said yesterday. The postal department owns 100 per cent of the shares of Nagad at the moment. Under a planned new ownership structure, private companies will collectively own 49 per cent shares of Nagad, and the rest will be controlled by the postal department, said Tanvir A Mishuk, managing director of Nagad.
