The firm said the agreement was signed with Saudi investment firm Kingdom Holding and Bahrain’s Batelco, on the terms previously set by Zain.

Kingdom Holding and Batelco made a joint offer for the stake last month.

“Zain signed the term sheet for the non-binding offer, with Kingdom Holding-Batelco consortium...to buy Zain’s 25 percent stake in Zain Saudi,” the firm said in a statement.

Offloading the 25-percent holding in Zain Saudi was the pre-requirement of a $12 billion takeover of parent Zain by the UAE’s Etisalat.

The deal fell through last month after Etisalat walked away.

Yet Zain is still pursuing the Zain Saudi stake sale, despite Etisalat withdrawing its offer last month, citing Zain’s divided board and regional unrest.
