Minority shareholders of Russia's largest gold producer Polyus Gold have agreed to sell a 59% stake in the company to billionaire Suleiman Kerimov, who plans to delist Polyus and take the company private, Bloomberg reported on November 4.

Currently the Kerimov family holds 40% in Polyus and will be able to increase the stake to over 98%, the agency reports, citing a regulatory claim filed by Sacturino Ltd controlled by Suleiman's son Said.

Polyus reportedly intends to delist its shares from the London Stock Exchange on December 3. The company has been considering following the Kremlin's exhortation for large corporates to return to Russia after it took its primary listing to London in 2012.

Sacturino will buy Polyus shares at $2.97, valuing the gold miner at $9bn, according to earlier reports.

Previously, the Kerimovs said that co-owners of the company Gavriil Yushvaev and Oleg Mkrtchan agreed to sell their stakes totalling some 40%, suggesting that another 18% will be acquired from other minority owners.

An independent committee set up by Polyus had said that the offer "materially" undervalued the company, although an improved or an alternative offer is not expected.

In September, Sberbank CIB estimated Polyus Gold's 2015 Ebitda at around $1bn-$1.1bn. The offer made by the Kerimovs therefore imply a 2015 EV/Ebitda of roughly 8.5-9, depending on the net result of both FX and gold hedging derivatives transactions, which have yet to expire and be settled, the analysts said.
