As of 31 December 2009[update] 69.92% of shares were owned by Highstat Limited, a company controlled by Alexei Mordashov. 25% of shares were owned by Siemens and 5.08% by minor shareholders.
In December 2011 Highstat acquired Siemens's stake in Power Machines for less than US$280 million (3.6 rubles per share), below the market price (4.9 rubles per share).[6] Power Machines was subsequently delisted from the MICEX-RTS stock exchange.[7] In August 2012 Highstat made a mandatory offer of 4.53 rubles (US$0.139) per share to the remaining minority shareholders, which the Investor Protection Association said was significantly undervalued.[7] Following a complaint filed by the association, the Federal Financial Markets Service fined Highstat 250,000 rubles.[8]
In 2017, the company's CEO Roman Filippov was placed under temporary arrest on suspicions of divulging State secrets.[9] Machine Powers was placed under US sanctions in 2018 for working to “support Russia’s attempted annexation of Crimea”,[10] leading to the loss of a $500-million contract in Vietnam,[11] a failed payment for a contract completed for Ukraine's DTEK,[12] and the sale of its 35% stake in Siemens Gas Turbine Technologies LLC.[13] In 2020, it was awarded the contract to build the 1.4 gigawatt Sirik power plant in Iran.[14] In 2022, Power Machines assembled and tested its first domestically made high-power gas turbine, enabling Russia to replace imported equipment made unavailable since US sanctions.[15]
