Dec 3 (Reuters) - Russian business conglomerate Sistema is not planning to further reduce its stake in online retailer Ozon , CEO Vladimir Chirakhov said on Thursday.

Ozon raised nearly $1 billion from its New York share listing on Nov. 24, marking Russia's biggest IPO in three years as investors rushed to capitalise on an e-commerce boom.

It is trading both on Nasdaq and the Moscow Exchange.

"Now we have a 180-day lock-up. But I can add that we don't plan to monetise our share in Ozon at all... We believe that the company's shares will grow within a few years," Chirakhov said during a conference call.

After all IPO procedures are completed, Sistema's stake in Ozon will decrease to 33.1% from 45%. (Reporting by Nadezhda Tsydenova; Writing by Caleb Davis; Editing by Susan Fenton)
