Kirill Shamalov

In April 2018, the United States imposed sanctions on him and 23 other Russian nationals. Since his February 2013 marriage to Vladimir Putin's daughter Katerina and to join the elite billionaires group close to Vladimir Putin, Shamalov had become a major shareholder in Sibur in less than 18 months and a year later had received a billion dollar loan from Gazprombank, which was under United States sanctions (EO 13662), and had purchased a 17% stake in Sibur from Gennady Timchenko, who was under United States sanctions (EO 13661).

In April 2017, Bloomberg reported that Shamalov sold his shares of Sibur that he purchased from Timchenko to Leonid Mikhelson, the other owner of Sibur.

In February 2013 at Igora, a small ski resort at the 54 km marker along the Priozerskoe highway (Russian: Приозерское шоссе ; A-121) near Sosnovo (Russian: Сосново ) in the Priozersky District of the Leningrad Oblast, Shamalov married Katerina Tikhonova, Putin's second daughter. In January 2018, Shamalov separated from his wife. He allegedly lost 50% of his wealth due to this separation.

Shamalov became an industry leader in 2012 when the owners of Sibur promoted him from Vice President of Business Administration to Deputy CEO. He was given a 4.3% stake in the company. With the help of a loan from Gazprombank, Shamalov purchased an additional 17% of Sibur from Gennady Timchenko, owner of Sibur, for roughly $2.2 billion.
