In late 2006, Pumpyansky bought out the parts of Melnichenko and Popov, acquiring full ownership of TMK, which he listed on the London Stock Exchange and raised $1 billion. Later on, he was forced to surrender his controlling share to state-owned banks as security for a $1.85 billion loan, but Pumpyansky successfully re-gained the control of TMK two years later. Apart from TMK, he now co-owns Sinara Group along with German industrial giant Siemens. Last year, he led the supervisory board of Rosselkhozbank, an agricultural lender and the fourth-largest bank in Russia, and today, Pumpyansky serves as the Chairman of the Board of Sinara Group and TMK. Through some of his companies, he also assists the facelift to a stadium that will host the 2018 World Cup in Ekaterinburg.
