Nebius
Nebius Group is a Dutch holding company that was the former parent entity of the Russian technology company Yandex. The company's primary business was its ownership stake in Yandex's international assets prior to their divestment. Its most notable corporate action was the July 2024 sale of all its Russian assets, including the search engine and Yandex Taxi businesses, to a consortium of Russian investors for $5.3 billion. This transaction was a direct result of international sanctions and restrictions on foreign ownership of Russian assets following the invasion of Ukraine.
