Mexican based, America Movil said it has agreed to buy back AT&T’s 8.27 percent stake in the company ending a 20 year partnership between the two.

The move enables AT&T to secure regulatory approval for its proposed takeover of DirecTV.

Its shareholders Inmobiliaria Carso and Control Empresarial de Capitales will buy the shares from AT&T International for USD 5.57 billion. AT&T said it expects to realise a profit of 8-10 cents a share from the sale, depending on the final tax on the sale.
