Producer
Rocky Mountain Steel / Orion Steel (Atlas Holdings)

Did you know2022
From 2006 until 2025, the largest supplier of heavy rail for the US freight railroad network — the backbone of US commerce and military logistics — was controlled by EVRAZ plc, a company majority-owned by Russian oligarch Roman Abramovich. EVRAZ acquired the Pueblo facility in 2006 and operated it as EVRAZ Rocky Mountain Steel. After Russia's February 2022 invasion of Ukraine and British government sanctions on Abramovich and EVRAZ plc, EVRAZ North America was placed for sale. For 19 years, the company that produced nearly half of all US freight railroad track was ultimately controlled by a Russian billionaire whose assets were subsequently frozen by the UK government. The sale to Atlas Holdings (Connecticut private equity) in June 2025 was the culmination of a 3-year process triggered by geopolitical sanctions — during which the largest US rail mill was in ownership limbo.
