Johannesburg - Bidvest Group has offered to buy shares it doesn't already own in drugmaker Adcock Ingram Holdings, it said on Monday, in a deal worth a potential 6 billion rand ($515 million).
Bidvest, a conglomerate with businesses ranging from food service to auto show rooms, already owns 34.5 percent of South Africa's second-largest drug maker and has offered 52 rand per share in cash for the remainder.
Adcock has the largest share of South Africa's over-the-counter medicines but has been trailing rivals as it struggles to raise sales while grappling with over-reliance on a heavily regulated home market and factories running below capacity.
Adcock shares jumped 5 percent to 52.76 rand at 0719 GMT, while those of Bidvest were up 1 percent.
Bidvest offered 4 billion rand to Adcock shareholders in 2013 for the initial 34.5 percent, sinking a rival bid from Chile's CFR Pharmaceuticals.
