International Holding Company, a full services management and investment firm, offered to acquire a 31.25% stake in Nutresa, a food-processing conglomerate, for $2.15bn. IHC said it has filed a request to tender for 25% to 31.25% of the firm at $15 per share. IHC, whose market capitalization has rocketed to $170bn within a matter of months, is controlled by the Royal Group -- a conglomerate that had backed Gilinski’s bid for Nutresa and lists Sheikh Tahnoon as its chairman.
