Turkey's largest soft drink bottler, Coca-Cola Icecek AS, plans to float on the Istanbul Stock exchange in May or June, in what is believed to be the largest Coca-Cola float since Coca-Cola Hellenic Bottling went public five years ago.

A company board member, speaking to Dow Jones newswire, said between 25% and 30% will be offered in an IPO to domestic and foreign investors.

CCI is 40% owned by Turkish brewing company Anadolu Efes Biracilik Ve Malt Sanayi AS (C.AEF), the flagship of Efes Beverage Group. The remaining 20% is controlled by the Ozgorkey family.

The plan for the IPO is to have both primary and secondary offerings, while existing shareholders will also sell some shares.
