OMZ was formed in 1996 in an incorporation of Ural Machine-Building Plants with ZSMK. Izhora Plants merged with OMZ in 1999 and the company was renamed OMZ (Uralmash-Izhora Group). In 2003 the company combined with Pilsen Steel and Skoda JS, the former steel and nuclear subsidiaries of Skoda Works. In 2008 CHETENG Engineering also joined.

The company's shares were delisted from the Moscow and London stock exchanges in 2014 "due to the economic inexpedience of supporting the insignificant free-float of less than 0.33% of the capital."[5]
