Sovcomflot reportedly intends to sell nearly a fifth of the company on the Moscow Exchange.
The Russian state-run shipping giant disclosed on Monday that it will sell a stake between 15.5% and 17%, raising RUB 42.3bn ($534m), Reuters reported.
Shares will cost between RUB 105 and RUB 117, with more pricing details expected in early October.
The newswire quotes an analyst saying those figures peg the shipowner as worth between RUB 250bn and RUB 270bn.
