Mansha's conglomerate greatly benefited from the privatization drive by the governments of the 1990s. Through this period, he made a number of acquisitions and buy-outs, including engineering at least one hostile takeover. When the dust settled, Mansha had acquired a controlling position in Adamjee Group, the country's largest non-life insurer. Nishat Mills also acquired two thermal plants near its DG Khan Cement Plants located in Dera Ghazi Khan District, Punjab, previously owned by the Saigol family.
