MOSCOW, March 14 (Reuters) - Russia's TCS Holding , which is controlled by the Interros group founded by Vladimir Potanin, said it will seek to integrate Rosbank into the holding to increase its share of Russia's financial market.

Potanin's Interros, one of the most powerful private investment companies in Russia, bought Rosbank from France's Societe Generale in 2022, followed by Tinkoff Bank from businessman Oleg Tinkov.

"The successful redomicilation of the group and the formation of a full-fledged corporate governance structure make it possible to launch strategic initiatives aimed at outstripping business growth, including non-organic business," Alexei Malinovsky, head Tinkoff Group's board, said.

TCS Holding, which owns online bank Tinkoff, said it would propose that shareholders consider integrating Rosbank into the group to "strengthen its financial market position".

The holding's board of directors has decided to initiate a buyback of up to 19 million of its own shares on the market, representing about 10 per cent of the company's share capital, it added.

TCS almost quadrupled net profit last year to 80.9 billion roubles ($883.5 million), it said. ($1 = 91.5650 roubles) (Reporting by Elena Fabrichnaya Editing by Guy Faulconbridge)
